The invention described herein relates to the field of process control and automated industrial manufacturing. Specifically, cloud controlled manufacturing execution systems and methods used for the monitoring and execution of pharmaceutical manufacturing processes. The invention further relates to the enhancement of distributed network systems, embedded systems, cloud computing, and computer programming technologies to produce higher quality more efficient drugs thereby minimizing cost.
Process control of commercial industrial plants has evolved through many stages. Initially, control paradigms would be from panels local to the manufacturing plant. However, this required a large labor resource(s) to attend to these dispersed panels, and there was no overall view of the process. The next logical development was the transmission of all plant measurements to a permanently manned central control room. Effectively, this was the centralization of all the localized panels, with the advantages of lower manning levels and easier overview of the process. Often the controllers were behind the control room panels, and all automatic and manual control outputs were individually transmitted back to plant in the form of pneumatic or electrical signals. However, while this seemingly provided a central control focus, the arrangement was inflexible as each control loop had its own controller hardware so system changes required re-configuration of signals by re-piping or re-wiring on an individual component or sub-system basis. This situation also required continual operator movement within a large control room in order to monitor the whole process. With standardization of electronic processors, high-speed electronic signaling networks, and electronic graphic displays it became possible to replace these discrete controllers with computer-based algorithms, hosted on a network of input/output racks with their own control processors. These could be distributed around the plant and would communicate with the graphic displays in the control room. The concept of “distributed control” was realized.
The introduction of distributed control allowed flexible interconnection and re-configuration of plant controls such as cascaded loops and interlocks as well as easy interfacing with other production computer systems. It enabled sophisticated alarm handling, introduced automatic event logging, removed the need for physical records such as chart recorders, allowed the control racks to be networked and thereby located locally in the plant to reduce cabling runs, and provided high level overviews of plant status and production levels. For large control systems, the general commercial name “Distributed Control System” (DCS) was coined to refer to proprietary modular systems which had high-speed networking and a full suite of displays and control racks, which all seamlessly integrated.
While the DCS was often tailored to meet the needs of large industrial continuous processes, in industries where combinatory and sequential logic was the primary requirement, the PLC (programmable logic controller) evolved out of a need to replace racks of relays and timers used for event-driven control. The old controls were difficult to re-configure and fault-find and PLC control enabled networking of signals to a central control area with electronic displays. Accordingly, PLCs were first developed for the automotive industry on vehicle production lines, where sequential logic was becoming very complex. It was soon adopted in a large number of other event-driven applications as varied as printing presses and water treatment plants.
Supervisory Control and Data Acquisition (“SCADA”) platforms were then developed. SCADA's history is rooted in distribution applications, such as power, natural gas, and water pipelines, where there is a need to gather remote data through potentially unreliable or intermittent low-bandwidth and high-latency links. SCADA systems use open-loop control with sites that are widely separated geographically. A SCADA system uses RTUs (remote terminal units, also referred to as remote telemetry units) to send supervisory data back to a control center. Most RTU systems generally have limited capacity to handle local controls while the master station is not available. However, more recently RTU systems have grown more capable of handling local controls.
Currently, the boundaries between DCS and SCADA/PLC systems are blurring. The technical limits that drove the designs of these various systems are no longer an issue. Many PLC platforms can now perform quite well as a small DCS, using remote I/O and are sufficiently reliable that some SCADA systems actually manage closed loop control over long distances with a relatively high degree of consistency. With the increasing speed of today's processors, many DCS products have a full line of PLC-like subsystems that were not offered when they were initially developed.
A Manufacturing Execution System (“MES”), generally speaking, is a computerized system used in manufacturing, to track and document the transformation of raw materials to finished goods. MES provides information that assists manufacturing decision makers understand how current conditions on the plant floor can be optimized to improve production output. MES works in real-time to enable the control of multiple elements of the production process (e.g. inputs, personnel, machines and support services). MES may operate across multiple function areas, for example: management of product across the product life cycle, resource scheduling, order execution and dispatch, production analysis and downtime management for overall equipment effectiveness (OEE), product quality, or track-and-trace paradigms. MES creates the “as-built” record, capturing the data, processes, and outcomes of the manufacturing process. This can be especially important in regulated industries, such as pharmaceutical(s) or biopharmaceutical(s), where documentation and proof of processes, events, and actions may be required for compliance and regulatory purposes.
A wide variety of systems arose using collected data for a dedicated purpose(s). Further development of these systems during the 1990s introduced overlap in functionality. A functional hierarchy was defined in which MES were situated at Level 3 between ERP at Level 4 and process control at Levels 0, 1, 2. In 2000, the ANSI/ISA-95 standard merged this model with the Purdue Enterprise Reference Architecture (“PERA”). With the publication of the third part of the standard in 2005, activities in Level 3 were divided over four main operations: (i) production, (ii) quality, (iii) logistics and (iv) maintenance. In modern parlance, the idea of MES is generally seen as an intermediate step between, on the one hand, an enterprise resource planning (ERP) system, and a supervisory control and data acquisition (SCADA) or process control system on the other.
With the advent of cloud computing, the Internet of Things (“IoT”) is poised to fundamentally change industrial manufacturing. Generally speaking, cloud computing is a model for enabling ubiquitous access to shared pools of configurable resources (such as computer networks, servers, storage, applications and services), which can be rapidly provisioned with minimal management effort, often over the Internet. For these reasons, cloud computing has become a significant vision for improvement in automated manufacturing industries. However, the challenges in cloud computing prevail as cloud grows in large scale in order to support huge numbers of high-performance process controllers; operating concurrently in manufacturing with zero downtime and no slowness, these challenges are impacting the decision to adopt cloud computing for process controller in manufacturing.
Finally, the globalization of pharmaceutical manufacturing requires a global approach to integration keeping in mind the overall objective of strong public health protection. To accomplish these needed goals there is a need to carry out the following actions. First, the artisan should use emerging pharmaceutical science, process control technology, computer and network programming, data analytics, and cloud computing technology to enhance commercial production, quality control, and quality assurance programs to target the highest risk areas. Second, an artisan should look to modern manufacturing techniques to integrate production at all levels and across a global scale. Third, the artisan should strive for consistency and predictability in its processes with an overall goal of production transparency from the line worker to a business unit to a regulating body (e.g. The Food and Drug Administration).
From the aforementioned, it will be readily apparent to those skilled in the art that a new manufacturing paradigm is needed in the production of pharmaceuticals and biopharmaceuticals. By using modern process control and computer programming techniques in conjunction with cloud control technologies, a new process control paradigm can be achieved with the overall goal of more efficient systems, reduced waste, and lower production costs. This, in turn, will allow higher quality drugs to be produced and offered to the patients and end users at a lower price.
Given the current deficiencies associated with cloud computing, process control, pharmaceutical and biopharmaceutical manufacturing, higher drug costs, and the fact that the demand from a public health standpoint is ever increasing, it becomes clear that providing a cloud based MES for use in pharmaceutical and biopharmaceutical manufacture is desirable. Specifically, using cloud computing to control the production of pharmaceuticals and biopharmaceuticals from a “quality by design” approach (i.e. where quality is designed into the production versus testing quality post-production) is advantageous. The present invention provides this solution.

“interface” means the communication boundary between two or more entities, such as a piece of software, a hardware device, or a user. It generally refers to an abstraction that an entity provides of itself to the outside. This separates the methods of external communication from internal operation, and allows it to be internally modified without affecting the way outside entities interact with it, as well as provide multiple abstractions of itself. It may also provide a means of translation between entities which do not speak the same language, such as between a human and a computer. The interface between a human and a computer is called a user interface. Interfaces between hardware components are physical interfaces. Interfaces between software exist between separate software components and provide a programmatic mechanism by which these components can communicate.

Such systems can range from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems with many thousands of field connections. All systems receive data received from remote sensors measuring process variables (PVs), compare these with desired set points (SPs) and derive command functions which are used to control a process though the final control elements (FCEs), such as control valves. The larger systems are usually implemented by Supervisory Control and Data Acquisition (SCADA) systems, or distributed control systems (DCS), and programmable logic controllers (PLCs), though SCADA and PLC systems are scalable down to small systems with few control loops.
“Internet of Things” (“IoT”) means the interconnection via the Internet of computing devices embedded in everyday objects, enabling them to send and receive data. The IoT allows objects to be sensed or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention.

“low-level language” means a programming language that provides little or no abstraction from a computer's instruction set architecture, commands or functions in the language map closely to processor instructions. Generally this refers to either machine code or assembly language. The word “low” refers to the small or nonexistent amount of abstraction between the language and machine language; because of this, low-level languages are sometimes described as being “close to the hardware”. Programs written in low-level languages tend to be relatively non-portable, mainly because of the close relationship between the language and the hardware architecture.
“memorization” means an optimization technique used primarily to speed up computer programs by storing the results of expensive function calls and returning the cached result when the same inputs occur again.
“microcontroller” means a small computer on a single integrated circuit. In modern terminology, it is similar to, but less sophisticated than, a system on a chip or SoC; an SoC may include a microcontroller as one of its components. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of Ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips.
“Mobile Wireless Sensor Network”) (“MWSN”) means mobile spatially distributed autonomous sensors, to monitor physical or environmental conditions, such as temperature, sound, pressure, pH, concentration, DO, pressure, magnetic, moisture, flow, fluid velocity, density, temperature, heat, etc. and to cooperatively pass their data through the network to other locations. The more modern networks are bi-directional, also enabling control of sensor activity.
“modbus” means a communication protocol used to share data between controllers. It was originally designed for Modicon PLCs but was adopted by many other manufacturers since it is an open architecture and thus has become an industry standard.
“Modular Programming” means a software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect of the desired functionality.
“MQ Telemetry Transport” means The IBM MQ Telemetry Transport (MQTT) v3 protocol is designed for exchanging messages between small devices on low bandwidth, or expensive connections, and to send messages reliably. It uses TCP/IP.
“multi-paradigm programming” means a programming language that supports more than one programming paradigm. The design goal is to allow programmers to use the best tool for the job. The concept is to provide a framework in which programmers can work in a variety of styles. This is common in complex systems architecture.
“Network latency” means time interval between the stimulation and response, or, from a more general point of view, a time delay between the cause and the effect of some physical change in the system being observed. Network latency in a packet-switched network is measured either one-way (the time from the source sending a packet to the destination receiving it), or round-trip delay time (the one-way latency from source to destination plus the one-way latency from the destination back to the source). Round-trip latency is more often quoted, because it can be measured from a single point. Note that round trip latency excludes the amount of time that a destination system spends processing the packet.
“OPC” means a set of standards that specify the communication of data between software applications and automation hardware. The acronym OPC originally stood for OLE for Process Control because it was based upon the Microsoft OLE (Object Linking and Embedding) technology. In fact, it was meant as the automation industries version of OLE but with the changes in Microsoft technology the term OLE has been dropped from the acronym. OPC now stands as a phrase to describe a set of standards for open connectivity in automation and process control.
“open Loop” means a system that does not monitor the output to adjust control. This is typically used on well behaved systems.
“paradigm” means a typical example or pattern; a model.
“process automation system” means a system interconnecting sensors, controllers, operator terminals and actuators to a computer for process automation control. A PAS is based on open standards in contrast to a DCS (distributed control system), which is traditionally proprietary.

It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered, and error-checked delivery of a stream of octets between applications running on hosts communicating by an IP network. Major Internet applications such as the World Wide Web, email, remote administration, and file transfer rely on TCP.
“transmission rate” means the number of bits which can be extracted from a medium. The maximum transmission rate describes the fundamental limitation of a network medium.

“inactive ingredient” (a.k.a. excipient) means a substance used as a carrier for the active ingredients of a drug or biologic. In addition, excipients can be used to aid the process by which a drug or biologic is manufactured. The active drug or biologic ingredient is then dissolved or mixed with an excipient. Excipients are also sometimes used to bulk up formulations with active drugs or biologics ingredients, to allow for convenient and accurate dosage. Examples of excipients, include but are not limited to, thickeners, binders, starches, gums, diluents, flavors, colors, emulsifiers, and preservatives.

Some of the ways by which crystals form are precipitating from a solution, melting, or more rarely deposition directly from a gas.
“chromatography” means a technique for the separation of mixtures. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation. Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for later use, and is thus a form of purification. Analytical chromatography is done normally with smaller amounts of material and is for establishing the presence or measuring the relative proportions of analytes in a mixture. The two are not mutually exclusive.

Essentially, a 5GL of the present invention is designed to make the computer solve the problem (i.e. higher quality more efficient pharmaceutical or biopharmaceutical production). This way, a programmer only needs to worry about what problems need to be solved and what conditions need to be met, without worrying about how to implement a routine or algorithm to solve them. In one embodiment, a 5GL of the present invention uses Prolog, OPS5, STRIPS, POP-11, C++, Perl, or Mercury programming language.

It will also be appreciated by those skilled in the art that the various steps herein for pharmaceutical or biopharmaceutical production are not required to be all performed or exist in the same production series. Thus, while in some embodiments, all steps and/or software programs and/or manufacturing execution systems described or mentioned herein are performed or exist, in other embodiments, one or more steps are optional (e.g., omitted, changed (in scope, order, placement, etc.) or the like. Accordingly, those of skill in the art will recognize that many modifications may be made without departing from the scope of the present invention.
The invention provides for a method of analyzing data that is compiled as a result of the manufacturing pharmaceuticals or biopharmaceuticals.

In a further embodiment, the invention provides for data analysis using path analysis. The path analysis will be initiated after the design phase and will be used to confirm the design level. On of ordinary skill in the art will appreciate that the path analysis will be a dynamic analysis depending on the complexity of the program modification. For example, the path analysis on the output of a drug product will be inherently more complex that the path analysis for the validation of an in-process material.

Another aspect of the invention relates to taking the data compiled during pharmaceutical or biopharmaceutical manufacture and using the analyzed data to create a historic record of the pharmaceutical or biopharmaceutical manufacture. The historic record is them transmitted via wireless distributed system of the invention and stored in one or a plurality of “cloud” based databases.

In one embodiment, the continuous analytics are used in an Enterprise Resource Planning (“ERP”) system or in a preferred embodiment; continuous analytics are used in an MES, which possesses attributes of an ERP system.
In another aspect of the present invention, predictive analytics are disclosed herein. One of ordinary skill in the art will appreciate that utilizing the historic record of the pharmaceutical or biopharmaceutical manufacturing processes will allow for more efficient manufacturing in subsequent production runs through the use of predictive analytics modeling on each pharmaceutical or biopharmaceutical sub-process as well as the entire pharmaceutical or biopharmaceutical manufacturing system at-large.

One of ordinary skill will understand that by separating the historic data will provide for greater data integrity since only those end users will a relevant need for the data will be able to access the data. In addition, more efficient transmission of data will occur over the wireless distributed system of the invention since the data can be partitioned and segregated.

By way of brief background, the Purdue Enterprise Reference Architecture (PERA) is a 1990s reference model for enterprise architecture developed by Dr. Theodore J. Williams and other members of the Industry-Purdue University Consortium for Computer Integrated Manufacturing. Generally speaking, the Purdue Reference Model, “95” provides a model for enterprise control, which end users, integrators, and vendors can share in integrating applications at key layers in the enterprise. The standard 5 level (Levels 0-4) structure was modified by the Manufacturing Enterprise Solutions Association (“MESA”). MESA introduced some structure into an MES by defining eleven (11) functions that set the scope of MES. In 2000, the ANSI/ISA-95 standard merged the MESA model with the Purdue Reference Model (“PRM”). From 2005-2013, additional or revised parts of the ANSI/ISA-95 standard defined the architecture of an MES into more detail, covering how to internally distribute functionality and what information to exchange internally as well as externally. Currently, the ANSI/ISA-95 is the global international standard for developing an automated interface between enterprise and control systems. For a graphical representation of the PERA reference model and the ANSI/ISA-95 standard, see

The analysis and analytics of the pharmaceutical or biopharmaceutical manufacturing occurs using any of the methods disclosed herein. (See, section V entitled “Data and Process Analytics”). The program executes, controls, and monitors and processes the data and stores the data in a using methods disclosed herein (See, section II entitled “Cloud Based Distributed Systems”).

Utilizing the historical record will provide pharmaceutical or biopharmaceutical manufacturers an “intelligent” perspective to manufacturing. Over time, the manufacturing execution system will teach itself and modify the pharmaceutical or biopharmaceutical manufacturing process in a way to obviate previous failures while at the same time continuously monitoring for new or potential failures. In addition, the invention comprises monitoring the data from initial pharmaceutical process, monitoring the data at the end of the pharmaceutical process, and monitoring the data from a routine maintenance schedule to ensure the system maintain data integrity and validation standards predetermined by the quality control unit.
Yet another aspect of the invention provides for the control and execution of a pharmaceutical or biopharmaceutical. manufacturing process from a MES of the invention whereby the MES controls and executes a start/stop paradigm and a corrective action paradigm.

In one embodiment, a MES of the present disclosure interfaces via a Soft PLC and/or a sensor note (a.k.a. a mote) to a sensor used to produce a measurable response to a change in physical condition in a pharmaceutical or biopharmaceutical manufacturing system, device or devices. One of ordinary skill understands that generally sensors are classified into three categories: (i) passive omni-directional sensors; (ii) passive narrow-beam sensors; and (iii) active sensors. Passive sensors sense the data without actually manipulating the environment by active probing. They are self powered; that is, energy is needed only to amplify their analog signal. Whereas, active sensors actively probe the environment, for example, a sonar or radar sensor, and they require continuous energy from a power source. Narrow-beam sensors have a well-defined notion of direction of measurement, similar to a camera. Omni-directional sensors have no notion of direction involved in their measurements. In one embodiment, the sensor(s) of the present invention can be passive or active. In a preferred embodiment, the sensor(s) of the invention are active to a pharmaceutical or biopharmaceutical manufacturing environment.
It will be appreciated by one of skill in the art that the type of sensor needed will be a direct function to the pharmaceutical or biopharmaceutical manufacturing process being controlled, executed, and/or monitored. For example, monitoring the potency of a vaccine will require different monitoring parameters that monitoring the pH of an antibiotic, which in turn will require different monitoring parameters that monitoring the temperature of a biologic product. In these situations, it will be appreciated by one of ordinary skill that either (i) the same sensors can be used with different detecting criteria or (ii) different types of sensors can be used to achieve the best level of monitoring for a specific pharmaceutical or biopharmaceutical manufacturing process.

A.) Powder Blending Processes/Systems
The mixing of free-flowing powders is a necessity in pharmaceutical or biopharmaceutical production. An effective mixing geometry is the starting point for many of these processes. Some geometries mix well; others do not. Particle properties generally include size distribution, shape, particle density, composition and internal structure. Bulk properties include flowability, bulk density, mixture quality, segregation tendency, dustiness and rheology. Fluctuations in raw material composition, feed rate, and process variables will also impact particle properties which can lead to off-specification drug product, active ingredients, inactive ingredients, components, in-process materials and equipment downtime. Furthermore, in a continuous manufacturing process of an active ingredient the last step whereby a variance can be introduced, mitigated, or managing effectively is the blending step. Accordingly, one of skill in the art, will understand that an MES of the present disclosure will be an advantage, since a variance in the active ingredient will obviate a production run. Accordingly, controlling, executing, and monitoring a powder blending system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure will be advantageous.
B.) Granulation Processes/Systems
Granulation is the process in which primary powder particles are made to adhere to form larger, multparticle entities called granules. It is generally occurs prior to tableting or pelleting. The granulation process combines one or more powder particles and forms a granule that will allow tabletting or the spheronization process to be within required limits. This way predictable and repeatable process is possible and quality tablets or pellets can be produced using tabletting or spheronization equipment.
One of skill in the art understands that granulation is carried out for various reasons, one of which is to prevent the segregation of the constituents of powder mix. Segregation is due to differences in the size or density of the component(s) of the mix. Normally, the smaller and/or denser particles tend to concentrate at the base of the container with the larger and/or less dense ones on the top. An ideal granulation will contain all the constituents of the mix in the correct proportion in each granule and segregation of granules will not occur. Many powders, because of their small size, irregular shape or surface characteristics, are cohesive and do not flow well. Granules produced from such a cohesive system will be larger and more isodiametric, both factors contributing to improved flow properties.
Additionally, some powders are difficult to compact even if a readily compactable adhesive is included in the mix, but granules of the same powders are often more easily compacted. This is associated with the distribution of the adhesive within the granule and is a function of the method employed to produce the granule.
For example, if one were to make tablets from granulated sugar versus powdered sugar, powdered sugar would be difficult to compress into a tablet and granulated sugar would be easy to compress. Powdered sugar's small particles have poor flow and compression characteristics. These small particles would have to be compressed very slowly for a long period of time to make a worthwhile tablet. Unless the powdered sugar is granulated, it could not efficiently be made into a tablet that has good tablet characteristics such as uniform content or consistent hardness.
In pharmaceutical or biopharmaceutical production, there are generally two (2) types of granulation. Wet granulation and dry granulation.
(i) Granulation Processes/Systems
In wet granulation, granules are formed by the addition of a granulation liquid onto a powder bed which is under the influence of an impeller (e.g. high-shear granulator), screws (e.g. twin screw granulator) or air (e.g. a fluidized bed granulator). The agitation resulting in the system along with the wetting of the components within the formulation results in the aggregation of the primary powder particles to produce wet granules. The granulation liquid contains a solvent which must be volatile so that it can be removed by drying, and be non-toxic. Typical liquids include water (WFI or pure water), ethanol, and isopropanol either alone or in combination. The liquid solution can be either aqueous based or solvent-based. Aqueous solutions have the advantage of being safer to deal with than solvents.
Water mixed into the powders can form bonds between powder particles that are strong enough to lock them together. However, once the water dries, the powders may fall apart. Therefore, water may not be strong enough to create and hold a bond. In such instances, a liquid solution that includes a binder is required. polyvinyl pyrrolidone (PVP), is one of the most commonly used pharmaceutical binders. PVP is dissolved in water or solvent and added to the process. When PVP and a solvent/water are mixed with powders, PVP forms a bond with the powders during the process, and the solvent/water evaporates (dries). Once the solvent/water has been dried and the powders have formed a more densely held mass, then the granulation is milled. This process results in the formation of granules. The process can be very simple or very complex depending on the characteristics of the powders, the final objective of tablet making, and the equipment that is available. In the traditional wet granulation method the wet mass is forced through a sieve to produce wet granules which is subsequently dried. Wet granulation is traditionally a batch process in the pharmaceutical production, however, the batch type wet granulations are not as efficient as continuous wet granulation. Accordingly, controlling, executing, and monitoring a wet granulation system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure will be advantageous.
(ii) Granulation Processes/System
In contrast, dry granulation is used to form granules without using a liquid solution because the product granulated may be sensitive to moisture and heat. Forming granules without moisture requires compacting and densifying the powders. In this process the primary powder particles are aggregated under high pressure. Sweying granulator or a roll compactor can be used for dry granulation. Generally, an artisan understands that dry granulation can be conducted under two processes; either a large tablet (slug) is produced in a heavy-duty tabletting press or the powder is squeezed between two counter-rotating rollers to produce a continuous sheet or ribbon of materials (roller compactor). When a tablet press is used for dry granulation, the powders may not possess enough natural flow to feed the product uniformly into the die cavity, resulting in varying degrees of densification. The roller compactor (granulator-compactor) uses an auger-feed system that will consistently deliver powder uniformly between two pressure rollers. The powders are compacted into a ribbon or small pellets between these rollers and milled through a low-shear mill. When the product is compacted properly, then it can be passed through a mill and final blend before tablet compression. Typical roller compaction processes consist of the following steps: (i) convey powdered material to the compaction area; (ii) compact powder between two counter-rotating rolls with applied forces; (iii) mill resulting compact to desired particle size distribution. Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a dry granulation system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure.
C.) Crystallization Processes/Systems
Generally speaking, crystallization is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Attributes of the resulting crystal depend largely on factors such as temperature, air pressure, and in the case of liquid crystals, time of fluid evaporation. Crystallization occurs in two major steps. The first is nucleation, the appearance of a crystalline phase from either a super cooled liquid or a supersaturated solvent. The second step is known as crystal growth, which is the increase in the size of particles and leads to a crystal state. An important feature of this step is that loose particles form layers at the crystal's surface lodge themselves into open inconsistencies such as pores, cracks, etc.
Crystallization is a key component of almost all processes in the manufacturing of pharmaceuticals. Whether for purification of intermediates, formation of a drug product, or prevention of crystallization in amorphous products, crystallization is essential in both processing and development. One of ordinary skill in the art will appreciate that several types of crystallizers are within the scope of the invention. For example, tubular crystallizers and mixed-suspension mixed-product removal (MSMPR) crystallizers. One of ordinary skill will appreciate that to effectively control the crystallization process in a pharmaceutical or biopharmaceutical environment, one needs to control time points and crystal mass to obtain optimum conditions. Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a crystallization system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure.
D.) Table Press Processes/Systems
The manufacture of oral solid pharmaceutical or biopharmaceutical dosage forms such as tablets is a complex multi-stage process under which the starting materials change their physical characteristics a number of times before the final pharmaceutical or biopharmaceutical dosage form is produced. Traditionally, tablets have been made by granulation (discussed supra), a process that imparts two primary requisites to formulate: (i) compatibility and (ii) fluidity. Both wet granulation and dry granulation (slugging and roll compaction) are used. Regardless of whether tablets are made by direct compression or granulation, the first step, milling and mixing, is the same; subsequent steps differ. Numerous unit processes are involved in making tablets, including (i) particle size reduction and sizing, (ii) blending, (iii) granulation, (iv) drying, (v) compaction, and (vi) coating. One of ordinary skill in the art will appreciate that various factors associated with these processes can seriously affect content uniformity, bioavailability, or stability.
Dispensing is the first step in many pharmaceutical manufacturing processes. Dispensing is one of the most critical steps in pharmaceutical manufacturing; as during this step, the weight of each ingredient in the mixture is determined according to dose. Dispensing may be done purely manual by hand scooping from primary containers and weighing each ingredient by hand on a weigh scale, manual weighing with material lifting assistance like vacuum transfer and bag lifters, manual or assisted transfer with automated weighing on weigh table, manual or assisted filling of loss-in weight dispensing system, automated dispensaries with mechanical devices such as vacuum loading system and screw feed system. Issues like weighing accuracy, dust control (LAF booths, glove boxes), during manual handling, lot control of each ingredient, material movement into and out of dispensary should be considered during dispensing. In order to mitigate and potential adverse event, fully automated dispensing is a preferred embodiment of the instant disclosure.
The sizing (size reduction, milling, crushing, grinding, pulverization) is another critical step in the process of pharmaceutical tablet manufacturing. In manufacturing of compressed tablets, the mixing or blending of several solid pharmaceutical ingredients is easier and more uniform if the ingredients are about the same size. This provides a greater uniformity of dose. A fine particle size is essential in case of lubricant mixing with granules for its proper function. Potential failures exist if the tablet press process is not controlled properly. These include but are not limited to (i) a possible change in polymorphic form of the active ingredient, rendering it less or totally inactive compared to the product specification; (ii) a decrease in bulk density of active compound and/or excipients, which may cause flow problem and segregation in the mix; and/or (iii) an increase in surface area from size reduction may promote the adsorption of air, which may inhibit wettability of the drug to the extent that it becomes the limiting factor in dissolution rate. One of ordinary skill in the art will appreciate that several embodiments of mill(s) and drying equipment is utilized and within the scope of the disclosure. For example, fluid energy mills, colloidal mills, ball mills, hammer mills, cutting mills, roller mills, and conical mills are within the scope of the disclosure.
After the preparation of granules (in case of wet granulation) or sized slugs (in case of dry granulation) (See the Section entitled “Granulation”) or mixing of ingredients (in case of direct compression), they are compressed to get a drug product. The compression is done either by single punch machine (stamping press) or by multi-station machine (rotary press). The tablet press is a high-speed mechanical device. It ‘squeezes’ the ingredients into the required tablet shape with extreme precision. It can make the tablet in many shapes, although they are usually round or oval. Also, it can press the name of the manufacturer or the product into the top of the tablet.
Each tablet is made by pressing the granules inside a die, made up of hardened steel. The die is a disc shape with a hole cut through its center. The powder is compressed in the center of the die by two hardened steel punches that fit into the top and bottom of the die. The punches and dies are fixed to a turret that spins round. As it spins, the punches are driven together by two fixed cams—an upper cam and lower cam. The top of the upper punch (the punch head) sits on the upper cam edge. The bottom of the lower punch sits on the lower cam edge.
The shapes of the two cams determine the sequence of movements of the two punches. This sequence is repeated over and over because the turret is spinning round. The force exerted on the ingredients in the dies must be carefully controlled. This ensures that each tablet is perfectly formed. Because of the high speeds, they need very sophisticated lubrication systems. The lubricating oil is recycled and filtered to ensure a continuous supply. Common stages occurring during compression include (i) top punch is withdrawn from the die by the upper cam bottom punch is low in the die so powder falls in through the hole and fills the die; (ii) bottom punch moves up to adjust the powder weight-it raises and expels some powder; (iii) top punch is driven into the die by upper cam Bottom punch is raised by lower cam Both punch heads pass between heavy rollers to compress the powder; (iv) top punch is withdrawn by the upper cam Lower punch is pushed up and expels the tablet is removed from the die surface by surface plate; (v) Repeat beginning at stage (i).
An artisan will appreciate that within the scope of the instant disclosure, several ancillary steps/unit processes can be included within a pharmaceutical or biopharmaceutical tablet press system of the invention. For example, tablet coating, tablet dedusting (removal of excess powder), tablet weighting, vision inspection systems/unit operations, granulation feeding devices (to carry materials from the granulation process to the tablet press process (especially in the instance of continuous manufacturing.
Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a tablet press system (and ancillary unit operations) in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure.
E.) Chromatography Processes/Systems
Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation. Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for later use, and is thus a form of purification. Analytical chromatography is done normally with smaller amounts of material and is for establishing the presence or measuring the relative proportions of analytes in a mixture. The two are not mutually exclusive and both types (preparative and analytical) are important steps in the production and quality control characterization of biologics.
One of skill in the art will appreciate that several chromatography techniques are known in the art and an artisan will understand that specific chromatography types will be a direct function of the type of pharmaceutical or biopharmaceutical being produced. For example, chromatography techniques by bed shape include column chromatography, planar chromatography, paper and thin later (TLC) chromatography. In addition, other chromatography techniques such as displacement, gas, liquid, affinity, ion-exchange, size exclusion, expanded bed adsorption, reverse plane, hydrophobic interaction, simulated bed-moving, fast protein liquid, countercurrent, and chiral are used by an artisan to produce pharmaceutical or biopharmaceuticals.
Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a chromatography system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure.
F.) pH Processes/Systems
pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the base 10 logarithm of the molar concentration, measured in units of moles per liter, of hydrogen ions. More precisely it is the negative of the base 10 logarithm of the activity of the hydrogen ion. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are basic. Pure water is neutral, at pH 7 (25° C.), being neither an acid nor a base. Contrary to popular belief, the pH value can be less than 0 or greater than 14 for very strong acids and bases respectively. pH measurements are important pharmaceutical and/or biopharmaceutical production since pH has a vital impact on the solubility, stability, permeability of a drug or biologic. For example, continuously monitoring pH will allow for determinations on uniform and stable production in relation to a product specification. In addition, continuously monitoring and adjusting pH will during biopharmaceutical manufacturing will optimize product yield whereby keeping costs of production steady.
Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a pH system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure.
G.) Liquid Mixing Processes/Systems
In pharmaceutical manufacturing, liquid mixing is a unit operation that involves manipulation of a heterogeneous physical system with the intent to make it more homogeneous. Mixing is performed to allow heat and/or mass transfer to occur between one or more streams, components, or phases. Modern pharmaceutical or biopharmaceutical manufacture almost always involves some form of liquid mixing. Some classes of chemical reactors are also mixers. With the right equipment, it is possible to mix a solid, liquid or gas into another solid, liquid or gas. The type of operation and equipment used during mixing depends on the state of materials being mixed (liquid, semi-solid, or solid) and the miscibility of the materials being processed.
(i) Liquid-Liquid Mixing Processes/Systems
Mixing of liquids occurs frequently in pharmaceutical and biopharmaceutical manufacture. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending on the Reynolds number of the flow. Turbulent or transitional mixing is frequently conducted with turbines or impellers; laminar mixing is conducted with helical ribbon or anchor mixers. Mixing of liquids that are miscible or at least soluble in each other occurs frequently in drug and biologic manufacturing processes. Generally, the momentum of the liquid being added is sometimes enough to cause enough turbulence to mix the two, since the viscosity of both liquids is relatively low. If necessary, paddle blending vessel can be used to complete the mixing process.
(ii) Liquid-Solid Mixing Processes/Systems
Liquid-solid mixing is typically done to suspend coarse free-flowing solids, or to break up lumps of fine agglomerated solids. In the first case, the particles can be lifted into suspension (and separated from one another) by bulk motion of the fluid; in the second, the mixer itself (or the high shear field near it) must destabilize the lumps and cause them to disintegrate. Suspension of solids into a liquid is done to improve the rate of mass transfer between the solid and the liquid. Examples include dissolving a solid reactant into a solvent, or suspending catalyst particles in liquid to improve the flow of reactants and products to and from the particles. The associated eddy diffusion increases the rate of mass transfer within the bulk of the fluid, and the convection of material away from the particles decreases the size of the boundary layer, where most of the resistance to mass transfer occurs. Axial-flow impellers are preferred for solid suspension, although radial-flow impellers can be used in a tank with baffles, which converts some of the rotational motion into vertical motion. When the solid is denser than the liquid (and therefore collects at the bottom of the tank), the impeller is rotated so that the fluid is pushed downwards; when the solid is less dense than the liquid (and therefore floats on top), the impeller is rotated so that the fluid is pushed upwards. The equipment preferred for solid suspension produces large volumetric flows but not necessarily high shear; high flow-number turbine impellers, such as hydrofoils, are typically used. Multiple turbines mounted on the same shaft can reduce power draw.
Very fine powders, such as some active ingredients, and components that have been spray dried may agglomerate or form lumps during transportation and storage. Starchy materials or those that form gels when exposed to solvent can form lumps that are wetted on the outside but dry on the inside. These types of materials are not easily mixed into liquid with the types of mixers preferred for solid suspension because the agglomerate particles must be subjected to intense shear to be broken up. In some ways, deagglomeration of solids is similar to the blending of immiscible liquids, except for the fact that coalescence is usually not a problem.
(iii) Liquid-Gas Mixing Processes/Systems
Liquids and gases are typically mixed for mass transfer to occur. For example, in the case of air stripping, gas is used to remove volatiles from a liquid. Typically, a packed column is used for this purpose, with the packing acting as a motionless mixer and the air pump providing the driving force. When a tank and impeller are used, the objective is typically to ensure that the gas bubbles remain in contact with the liquid for as long as possible. This is especially important if the gas is expensive, such as pure oxygen, or diffuses slowly into the liquid. Mixing in a tank is also useful when a slow chemical reaction is occurring in the liquid phase, and so the concentration difference in the thin layer near the bubble is close to that of the bulk. This reduces the driving force for mass transfer. If there is a relatively fast chemical reaction in the liquid phase, it is sometimes advantageous to disperse but not re-circulate the gas bubbles, ensuring that they are in plug flow and can transfer mass more efficiently.
Rushton turbines have been traditionally used do disperse gases into liquids, but newer options, such as the Smith turbine and Bakker turbine are becoming more prevalent. One of the issues is that as the gas flow increases, more and more of the gas accumulates in the low pressure zones behind the impeller blades, which reduces the power drawn by the mixer. Newer designs, such as the GDX impeller, have mitigated this problem.
At a commercial production scale for the manufacture of drugs or biologics, regardless of the type of medium being mixed (i.e. liquid-liquid, solid liquid, liquid-gas), efficient consistent mixing can be difficult to achieve. An artisan understands that a great deal of process development goes into designing and improving mixing processes. Generally, mixing at a production scale is done in batches, inline, or with help of static mixers. Some applications require the use of multi-shaft mixers, in which a combination of mixer types are used to completely blend the product. In addition to performing typical batch mixing operations, some mixing can be done continuously. However, given the high regulatory requirements of manufacturing drugs and biologics, having the ability to continuously mix at consistent reproducible quality level will be desired. One aspect of the invention achieves this need.
Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a liquid mixing system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure.
H.) Water-Based Processes/Systems
Pharmaceutical and/or biopharmaceutical water systems are critical in parenteral aseptic manufacturing processes because of their influence on final product quality. Water of pharmaceutical and biopharmaceutical quality is mainly used as a part of the product in formulation processes and as a cleaning agent for vessels and accessories in direct contact with the drug product, active ingredients, inactive ingredients, components, and in-process materials during manufacture. Pharmaceutical water installations must adhere to technical design criteria, most of which are included in international regulatory guidelines.
(i) Chilled Water Systems
Pharmaceutical chillers are important parts of the drug-manufacturing industry. Nearly all drugs or biologics require chilled water in their manufacturing, from antibiotics to complex biologic medications. Chillers provide precise control over the water-chilling process. Pharmaceutical chillers come as central process chillers and compact process chillers. Central process chillers can handle 10 to 200 tons, and compact process chillers work well for 1 to 40 tons. Compact process chillers are smaller, which makes them ideal for small spaces. All pharmaceutical chillers feature components that include evaporators, pumps, refrigerant relief valves, cooling towers and pipes, condensers, compressors, filters, fans, and tanks. They come with either an air or water condenser and come in four (4) main types reciprocating, screw-driven, centrifugal, and absorption designs.
(ii) Clean-In-Place (CIP) Systems
Clean-in-place (CIP) is a method of cleaning the interior surfaces of pipes, vessels, process equipment, filters and associated fittings, without disassembly. Up to the 1950s, closed systems were disassembled and cleaned manually. The benefit to industries that use CIP is that the cleaning is faster, less labor-intensive, and poses less of a chemical exposure risk to humans. Depending on the cleaning needed, elevated temperature and chemical detergents are often employed to enhance cleaning effectiveness. An artisan will appreciate that critical parameters must be met and remain within the production specification for the duration of the product cycle. If the specification is not reached or maintained, cleaning will not be ensured and will have to be repeated. Critical parameters include temperature, flow rate/supply pressure, chemical concentration, chemical contact time, and final rinse conductivity.
(iii) Clean Steam Systems
Clean steam is used in the manufacture of pharmaceuticals and biopharmaceuticals in processes where steam or its condensate can come into contact with a pharmaceutical or biopharmaceutical. The main use of clean steam in pharmaceutical or biopharmaceutical manufacturing is for sterilization of products, or more usually, equipment. In a majority of cases, steam cleaning is encountered in the manufacture of injectable solutions, in biopharmaceutical manufacturing where a sterile environment must be created to grow a biological production organism (bacterial, yeast, or animal cell), and in the manufacture of sterile solutions, such as ophthalmic products.
(iv) Water-For-Injection (WFI) Systems
Water for injection (WFI) is water of extra high quality without significant contamination. A sterile version is used for making solutions that will be given by injection or will come in contact with human tissue before such use other substances generally must be added to make the solution more or less isotonic. A non-sterile version may be used in manufacturing with sterilization occurring later in the production process. WFI is generally made by distillation or reverse osmosis. It should contain less than a milligram (mg) of elements other than water per 100 ml. Versions with agents that stop bacterial growth are also available.
Based on the foregoing, it will be apparent to one of ordinary skill that consistent application of a water-based system in a pharmaceutical or biopharmaceutical manufacturing process will be advantageous. Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a water-based system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure.
I.) Finishing and Packaging Processes/Systems
Finishing and packaging of pharmaceuticals are important aspects of the pharmaceutical manufacturing process given that the finished product is ultimately distributed to the consumer. The need for safe uniform packaging is apparent to one of skill in the art.
(i) Filling Systems
Aseptic filling of sterile drugs, also known as sterile filling, is one of the most critical processes in biopharmaceutical manufacturing. This is due to its highly technique driven processes and the potential safety impact to the end user, usually an already compromised patient. There are only indirect safeguards for the sterility of the filled drug after it is stoppered and capped in the cleanroom. Unlike terminal sterilized filled drugs, the stability of the aseptic filled drugs will be affected by steam autoclave, dry heat ovens, Ethylene Oxide, and irradiation, either Cobalt 60 Gamma or E Beam. Thus the need to utilize an aseptic process to fill certain biological and pharmaceutical drugs. Virtually any solution, powder, or suspension can be terminally sterilized prior to the aseptic fill/finish process. Typically sterile drugs are aseptic fill/finish in molded glass bottles, tubular glass vials, tubular glass syringes, and glass ampoules. Solutions can also be subsequently lyophilized in a sterile dryer to further stabilize drugs. The more unique the product or container system, the greater the technical or operational challenges. Accordingly, it is an object of the present invention to overcome these challenges.
Aseptic filling is an aseptic process that requires the close coordination and complex interaction between manufacturing personnel, sterilized drug or biologic product, the fill/finish equipment system, cleanroom and support facilities, and sterilized filling components. The aseptic fill/finish methods can vary between an early clinical phase hand fill, to small volume semi-automated filling to the fully automated high-volume over multiple day production batches.
The cleanrooms are controlled areas and in conjunction with the supporting utility systems and facility infrastructure, create the environmental envelop in which the aseptic fill/finish process operates. As with the other components of the aseptic processing, the cleanrooms area complex combination of physical rooms and areas, utilizing High Efficiency Particulate Air (HEPA) to create unidirectional air patterns, maintenance of positive pressure between rooms in conjunction with constant air changes, and sanitization processes. All of this operates with constant environmental monitoring (EM). All components and supplies that are required during the aseptic fill/finish operation must be either sterilized or sanitized. Sterilization is usually completed with pass-through steam autoclaves, dry-heat oven, or tunnel and sanitized cleanroom airlocks.
One of ordinary skill will understand that the filling components can also vary per the drug and production requirements. Tubular Type I glass vials are predominately used for Small Volume Parenterals (SVP) and sterile lyophilization and blown Type II glass bottles for Large Volume Parenterals (LVP). Tubular Type I glass stock is also predominately used for aseptic syringe production.
The stoppering of the vial provides the sterile seal of the drug from the environment and a crimp-seal cap ensures the long term integrity. The stopper also provides a barrier to gas and oxygen to the drug ensuring long term stability. Elastomeric closures (stoppers) that are used for parenteral solutions are formulated to ensure product stability and patient functionality. Two of the basic styles of closures are the “plug” for sterile solutions and the “leg” for sterile lyophilization. Some of the considerations should be given to size, type and number of needle punctures, water vapor transmission rate, ability to retain bound water, gas transmission, stoppering equipment of the filling line and potential extractables.
There are many ways to aseptically fill/finish sterile drugs, which includes the traditional solution filling of glass vials and syringes, sterile powder fills, sterile lyophilization, and blow-fill-seal. In addition, an artisan will appreciate that there are many considerations in the selection of aseptic filling equipment including solution volume, fill tolerance, production throughput, drug viscosity, drug foaming, gas blanketing, drug temperature, potent compounds, drug stability, and reactivity.
Sterile preparation of the vials and bottles is achieved by rinsing/washing to remove endotoxins. The glass vials and bottles are depyrogenation usually with hot air. This is accomplished in a batch mode with an oven, or a continuous process with a tunnel that connects the bottle washer to the filling station.
The solution filling process will include the transport of sterilized vials and bottles, orientation to the filling station, a means for check weighing, stoppering and crimping stations. For high speed lines, there will also be accumulation tables and vial load/loading stations.
Industry wide, there is an increased effort from pharmaceutical and biopharmaceutical manufacturers to improve consistency in aseptic processing and pharmaceutical or biopharmaceutical filling. This is done in an effort to increase quality and decrease costs in the highly technical process. It is an object of the present invention to oversome these deficiancies.
Based on the foregoing, it will be apparent to one of ordinary skill that consistent application of a filling system in a pharmaceutical or biopharmaceutical manufacturing process will be advantageous. Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a filling system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure.
(ii) Dry Heat Sterilizers
Dry heat sterilization is an important aspect of finishing and packaging in pharmaceutical or biopharmaceutical production. The dry heat sterilization process is accomplished by conduction; that is where heat is absorbed by the exterior surface of an item and then passed inward to the next layer. Eventually, the entire. item reaches the proper temperature needed to achieve sterilization. The proper time and temperature for dry heat sterilization is 160° C. (320° F.) for 2 hours or 170° C. (340° F.) for 1 hour. Instruments should be dry before sterilization since water will interfere with the process. Dry heat destroys microorganisms by causing coagulation of proteins and thus in important for biologics. Generally speaking, there are two (2) types of hot air convection sterilizers: (i) Gravity convection and (ii) Mechanical convection. Additionally, one of ordinary skill in the art will appreciate that a plurality of instruments can be used in a dry heat sterilization process including a hot air oven and glass bead sterilizers.
Based on the foregoing, it will be apparent to one of ordinary skill that consistent application of a dry heat sterilizer system in a pharmaceutical or biopharmaceutical manufacturing process will be advantageous. Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a dry heat sterilizer system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure.
(iii) Lypholizers
Lyophilization, otherwise known as freeze-drying is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze-drying works by freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublime directly from the solid phase to the gas phase.
Pharmaceutical and biopharmaceutical companies use freeze-drying to increase the shelf life of the products, such as live virus vaccines, biologics' and other injectables. By removing the water from the material and sealing the material in a glass vial, the material can be easily stored, shipped, and later reconstituted to its original form for injection. Another example from the pharmaceutical industry is the use of freeze drying to produce tablets or wafers, the advantage of which is less excipient (components or inactive ingredient(s) as the case may be) as well as a rapidly absorbed and easily administered dosage form. Freeze-dried pharmaceutical products are produced as lyophilized powders for reconstitution in vials and more recently in prefilled syringes for self-administration by a patient.
Examples of lyophilized biological products include many vaccines such as Measles Virus Vaccine Live, Typhoid Vaccine, Meningococcal Polysaccharide Vaccine Groups A and C Combined. Other freeze-dried biological products include Antihemophilic Factor VIII, Interferon alfa, anti-blood clot medicine Streptokinase, and Wasp Venom Allergenic Extract.
Many biopharmaceutical products based on therapeutic proteins such as monoclonal antibodies require lyophilization for stability. Examples of lyophilized biopharmaceuticals include blockbuster drugs such as Etanercept, Infliximab, Rituximab and Trastuzumab. Freeze-drying is also used in manufacturing of raw materials for pharmaceutical products. Active Pharmaceutical Product Ingredients (APIs) are lyophilized to achieve chemical stability under room temperature storage. Bulk lyophilization of APIs is typically conducted using trays instead of glass vials.
Generally speaking there are four (4) stages necessary to complete the lyophilization process: (i) pretreatment, (ii) freezing, (iii) primary drying, and (iv) secondary drying.
Pretreatment includes any method of treating the product prior to freezing. This may include concentrating the product, formulation revision (i.e., addition of components to increase stability, preserve appearance, and/or improve processing), decreasing a high-vapor-pressure solvent, or increasing the surface area. In many instances the decision to pretreat a product is demanded by cycle time or product quality considerations.
In a scaled commercial production process freezing is usually done using a freeze-drying machine. In this step, it is important to cool the material below its triple point, the lowest temperature at which the solid, liquid and gas phases of the material can coexist. This ensures that sublimation rather than melting will occur in the following steps. Larger crystals are easier to freeze-dry. To produce larger crystals, the product should be frozen slowly or can be cycled up and down in temperature. This cycling process is called annealing. Usually, the freezing temperatures are between −40° C. and −90° C. and more preferably between −50° C. and −80° C. The freezing phase is the most critical in the whole freeze-drying process, because the product can be spoiled if improperly done.
During the primary drying phase, the pressure is lowered, and enough heat is supplied to the material for the ice to sublime. The amount of heat necessary can be calculated using the sublimating molecules' latent heat of sublimation and other methods known in the art. In this initial drying phase, between 91-97% of the water in the material is sublimed. In a preferred embodiment, 93% to 95% of the water in the material is sublimated. In the case of pharmaceuticals or biopharmaceuticals, this phase may be slow (in the order of 2 or 3 days), because, if too much heat is added, the material's structure may be altered, which would obviate the product specification or fall outside the quality control parameters. In this phase, pressure is controlled through the application of partial vacuum. The vacuum speeds up the sublimation, making it useful as a deliberate drying process. Furthermore, a cold condenser chamber and/or condenser plates provide a surface(s) for the water vapor to re-solidify.
The secondary drying phase aims to remove unfrozen water molecules, since the ice was removed in the primary drying phase. This part of the freeze-drying process is governed by the material's adsorption isotherms. In this phase, the temperature is raised higher than in the primary drying phase, and can even be above 0° C., to break any physico-chemical interactions that have formed between the water molecules and the frozen material. Usually the pressure is also lowered in this stage to encourage desorption. After the freeze-drying process is complete, the vacuum is usually broken with an inert gas, such as nitrogen, before the material is sealed. At the end of the operation, the final residual water content in the product is extremely low, around 0.5% to 6%. In a preferred embodiment, the residual water content is between 1% to 4%.
Based on the foregoing, it will be apparent to one of ordinary skill that consistent application of a pyophilizaton system in a pharmaceutical or biopharmaceutical manufacturing process will be advantageous. Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a lyophilizer system in a pharmaceutical or biopharmaceutical manufacturing process utilizing a “cloud” based MES of the present disclosure.
(iv) Vial Inspection Systems
A vial inspection system is an important aspect of finishing and packaging of pharmaceutical and biopharmaceutical manufacture. It is an important criteria for the quality control release and must be consistently applied in order to detect drug products that are outside of critical quality control parameters. Vial inspection systems come in a variety of forms, with some being manual (i.e. visually inspected by humans). Other automated or semi-automated vial inspection systems exists and use a wide range of technologies. For example, some systems utilize light scattering processes, photo equipment, or a hybrid of technologies to detect defects in both the drug products and defect on the vials.
Irrespective of the technology selected for automated inspection, several operational parameters (e.g., machine settings) and product properties play a key role in determining the performance of the system. Detailed characterization and optimization of these parameters are critical to developing a consistent vial inspection process. Each technology needs to be qualified for its ability to detect faulty containers and to ensure that non-defect containers will not be rejected. This qualification requires a series of experiments using standard defect sets to challenge the AIM. Careful selection of experimental conditions (i.e., defect sets and machine settings) is important to minimize the number of evaluations and still generate conclusive data for entire process space.
Given the importance of conforming to a quality control specification and the fact that vial inspection occurs near the end of the pharmaceutical or manufacturing process, it will be apparent to one of ordinary skill that consistent application of a vial inspection system in a pharmaceutical or biopharmaceutical manufacturing process will be advantageous. Accordingly, in one embodiment, the invention comprises controlling, executing, and monitoring a vial inspection system in a pharmaceutical or biopharmaceutical-manufacturing process utilizing a “cloud” based MES of the present disclosure.
(v) Supply Chain Management
Proper supply chain management of packaged drugs or biologics is critical to provide quality drug products to end-users. This includes monitoring traditional areas of the supply chain including vial inspection, packaging, product protection, storage, and distribution. Specifically, from the point when the drug or biologic is packaged until it reaches the end-user (See,
(vi) Track and Trace Systems
In the context of pharmaceutical or biopharmaceutical manufacture and distribution, tracking and tracing relates to the process of determining the current and past locations of a unique drug or biologic (or a pallet, or carton, as the case may be). In response to a growing number of recall incidents, a wave of software, hardware, consulting and systems vendors have emerged over the last few years to offer a range of traceability solutions and tools for industry. Radio-frequency identification and barcodes are two common technology methods used to deliver traceability. RFID is synonymous with track-and-trace solutions, and has a critical role to play in supply chains. RFID is a code-carrying technology, and can be used in place of a barcode to enable non-line of sight-reading. Deployment of RFID was earlier inhibited by cost limitations but the usage is now increasing. Barcoding is a common and cost-effective method used to implement traceability at both the item and case-level. Variable data in a barcode or a numeric or alphanumeric code format can be applied to the packaging or label. The secure data can be used as a pointer to traceability information and can also correlate with production data such as time to market and product quality.
Based on the foregoing, an artisan will appreciate that a disadvantage of the current state of the art does not allow for additional data to be inserted onto the drug or biopharmaceutical “tag” after it is placed into the supply chain. It is an object of the present invention to provide an advantage to track and trace systems in the pharmaceutical or biopharmaceutical supply chain. Accordingly, in one embodiment of the present invention, quality control and production data is included into the product “tag” for a certain drug or biologic produced with a “cloud” based MES of the present disclosure. One of ordinary skill in the art, will appreciate that continuous monitoring of quality control parameters in the supply chain will provide for more accurate quality control of drugs or biologics by the time it reaches the end user. For example, depending on the geographic location of the end-user and circumstances surrounding the need for treatment (i.e. a natural disaster, etc), delivery of the drugs or biopharmaceuticals could take weeks, months, etc.
Additionally, not all cold chain products are the same and the need for monitoring temperature and other quality parameters differs for each type of drug product.
In one embodiment, the invention provides for a method of monitoring quality of a drug product utilizing a “cloud” based MES of the instant disclosure whereby the drug product quality information is transmitted via wireless DCS of the invention and whereby the quality parameters are set forth by the quality control unit are transmitted via a “cloud” based storage database.
J.) Cell Culture Processes/Systems
Cell culture is the process by which cells are grown under controlled conditions, generally outside of their natural environment. Cell culture conditions can vary for each cell type, but artificial environments consist of a suitable vessel with substrate or medium that supplies the essential nutrients (amino acids, carbohydrates, vitamins, minerals), growth factors, hormones, and gases (CO2, O2), and regulates the physio-chemical environment (pH buffer, osmotic pressure, temperature). The cell culture process is an important step in the production of biopharmaceuticals.
(i) Cell Banking
A cell bank is a facility within a pharmaceutical or biopharmaceutical (or sometimes off-site) that stores cells of specific genome for the purpose of future use in a product or medicinal needs. They often contain expansive amounts of base cell material that can be utilized for various production runs. The advantages of cell banks, if properly monitored, is that the facilities will include a detailed description and history of the cells and thus initial quality control parameters will be readily determined by a quality control unit.
(ii) Bioreactor
A bioreactor refers generally to any manufactured or engineered device that supports a biologically active environment. Bioreactor design is a relatively complex engineering task, which is studied in the discipline of biochemical engineering. Under optimum conditions, the microorganisms or cells are able to perform their desired function with limited production of impurities. The environmental conditions inside the bioreactor, such as temperature, nutrient concentrations, pH, and dissolved gases (especially oxygen for aerobic fermentations) affect the growth and productivity of the organisms. The temperature of the fermentation medium is maintained by a cooling jacket, coils, or both. Particularly exothermic fermentations may require the use of external heat exchangers. Nutrients may be continuously added to the fermenter, as in a fed-batch system, or may be charged into the reactor at the beginning of fermentation. The pH of the medium is measured and adjusted with small amounts of acid or base, depending upon the fermentation. For aerobic (and some anaerobic) fermentations, reactant gases (especially oxygen) must be added to the fermentation. Since oxygen is relatively insoluble in water (the basis of nearly all fermentation media), air (or purified oxygen) must be added continuously. The action of the rising bubbles helps mix the fermentation medium and also “strips” out waste gases, such as carbon dioxide. In practice, bioreactors are often pressurized; this increases the solubility of oxygen in water. In an aerobic process, optimal oxygen transfer is sometimes the rate limiting step. Oxygen is poorly soluble in water—even less in warm fermentation broths—and is relatively scarce in air (20.95%). Oxygen transfer is usually helped by agitation, which is also needed to mix nutrients and to keep, the fermentation homogeneous. Gas dispersing agitators are used to break up air bubbles and circulate them throughout the vessel.
