Description

FIELD OF THE INVENTION

The present invention generally pertains to a system and methods for delivering aerosolized substance to a natural orifice of the body.

BACKGROUND OF THE INVENTION

Blow-Fill-Seal (BFS) technology is a manufacturing technique used to produce small (0.1 ml) and large (<500 ml) liquid-filled containers. The basic concept of blow-fill-seal and form-fill-seal (referred to interchangeably hereinafter as BFS) is that a container is formed, filled and sealed in a continuous process without human intervention in a sterile or aseptic enclosed area. Thus, this technology can be used to sterile or aseptically packaging and manufacturing of pharmaceutical liquid dosage forms.

There are several ways of manufacturing. According to one method, the processes begun as pharmaceutical grade plastic resin is vertically heat-extruded through a circular throat to form a hanging tube (parison). This extruded tube is then enclosed within a two-part mold and the tube is cut above the mold. The mold is zone, or a sterile filling space, where filling needles (mandrels) are lowered and used to inflate the plastic to form a container within the mold. Following formation of the container, the mandrel is used to fill the container with the liquid. Following filling, the mandrels are retracted and a secondary top mold seals the container. All actions take place within the sterile enclosed area, a sterile shrouded chamber within the machine. The product can then be discharged to a non-sterile area for labeling, packaging and distribution.

BFS technology reduces personnel intervention, making it a more robust method for aseptic preparation of sterile pharmaceuticals. BFS is used for the filling of vials for parenteral preparations and infusion, eye drops, and inhalation products. Generally, the containers are made of polyethylene and polypropylene.

It is therefore a long felt need to provide a system which provides an efficient delivery of a substance to a target site from such BFS containers, provides sufficient material to the target site, and ensures reproducibility.

In preferred embodiments of the device, the device comprises a delivery mechanism and a medicament capsule, as described hereinbelow. The device can apply a broad range of drugs and materials to the nasal cavity for local effect, deliver a broad range of drugs and materials through the nasal cavity to the systemic circulation, deliver a broad range of drugs and materials through the nasal cavity to the central nerve system (CNS) the brain, spinal cord and associated nerves, and any combination thereof.

The drugs to be applied could be, but are not limited to, pharmaceuticals, natural compounds, biologics, hormones, peptides, proteins, viruses, cells, stem cells and any combination thereof.

However, it should be emphasized that the device can be provided alone as well as in combination with a capsule.

In some cases, the capsule would be provided with a known medicament within the same and in other cases the capsule would be ‘filled’ with the medicament just before use.

In some embodiments of the present invention, the device operating characteristics and the substance characteristics can be jointly optimized to maximize uptake of the substance at the desired site. In preferred variants of such embodiments, uptake is further optimized by exploiting synergies between delivery characteristics generated by the device and by the formulation or composition of the delivered material

In some embodiments, the substance comprises one or more agents to optimize delivery through the mucosal membrane by means of mucoadhesive agent and/or a permeability enhancer agent and/or a particulate formulation in the nano-particle or macro-particle range, and any combination thereof. In such embodiments, the combination of the device and substance enhance the delivery of the active agent to the target area (nasal epithelium and more specifically olfactory epithelium) and from there to the target tissue (for example the brain).

A non-limiting example is a composition comprising a drug to be delivered and at least one chemical permeation enhancer (CPE). In a preferred embodiment, the composition contains two or more CPEs which, by using a nasal delivery device, affect in an additive manner or behave synergistically to increase the permeability of the epithelium, while providing an acceptably low level of cytotoxicity to the cells. The concentration of the one or more CPEs is selected to provide the greatest amount of overall potential (OP). Additionally, the CPEs are selected based on the treatment. CPEs that behave primarily by transcellular transport are preferred for delivering drugs into epithelial cells. CPEs that behave primarily by paracellular transport are preferred for delivering drugs through epithelial cells. Also provided herein are mucoadhesive agents that enable the extension of the exposure period of the target tissue/mucus membrane to the active agent, for the enhancement of delivery of the active agent to and through the mucus membrane.

In contrast to prior-art nasal delivery devices and technologies, the devices of the present invention can produce a fine aerosol in the nasal cavity or other desired body orifice at the target area and at the location of the target tissue instead of producing the aerosol only within the device or immediately after exit from the device. Utilizing the pressure as a driving force and the air as a carrier allows the material to be released from the nozzle as a mixture of aerosol and a pre-aerosolized state. The properties of the resultant aerosol are typically dependent on the properties of the device and of the medium into which the device is discharged. The properties of the device which affect the aerosol characteristics are the delivery pressure, the volume of the delivery gas, the characteristics of its orifice and time of activate.

In some embodiments, the aerosol properties are fairly independent of the delivered substance, while, in other embodiments, the pressure, volume, orifice characteristics, and delivered substance properties can be co-optimized.

In prior-art devices the aerosol is produced in proximity exit of the device. Typically, the aerosol comprises a wide “fan” of aerosol and a low driving force. Therefore, large droplets typically deposit very close to the exit from the device, while smaller droplets tend to quickly contact the walls of the passage, so that deposition is typically predominantly close to the delivery end of the device, with little of the substance reaching desired sites deeper in the body orifice, such as the middle and superior turbinates of the nose. In the present invention the aerosol created, due to the pressurized air carrier, reaches the upper regions of the nasal cavity.

Reference is now made to FIG. 1A-B, disclosing a device according to one embodiment of the present invention. FIG. 1A shows an exploded view of the device, while FIG. 1B shows the device fully assembled.

The pressurized-fluid container (2) will fit over the air chamber gate (3), with the first gate O-ring and the second gate O-ring providing airtight seals before activation so that compressed gas is storable between the air chamber gate (3) and the pressurized-fluid container (2).

As shown in the Figs. the base of the device forms the activation button (4); to activate, the activation button (4) is pressed upward, then the air chamber gate (3) is drawn downwardly, which removes the sealing of the upper O-ring (78 in FIGS. 7A-7B). The movement of the air chamber gate (3) opens a gap between the pressurized-fluid container (2) and the BFF nose piece (1), allowing the pressurized-fluid to escape from container 2, enter BFF nose piece (1) (after the same has been pierced by the piercing needle 79, shown in FIGS. 7A-7B), and entrain the substance to the nasal cavity.

Subsequently, as depicted in FIG. 6E, pressurized fluid (air, nitrogen etc.) flows from its container (62) to the drug-containing BFS and carries the drug (liquid phase, solid powder particles etc.) (51) outwardly.

One should also note that this example is shown for the same invention but with another kind of pressurized gas container and a different way of compressed gas discharge (by puncturing the container rather than the gate that is shown in the previous figures.
