This Non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No(s). TW106118744 filed in Taiwan, Republic of China Jun. 6, 2017, the entire contents of which are hereby incorporated by reference.
The present invention relates to a method for producing standard-compliant application document, and more particularly, to a method for producing a submission document conforming to a new medicine or a medical material application.
With clinical research gradually towards electronic, which is called eClinical trial, the using of the Clinical Data Management System (CDMS) becomes more popular. Like the hospital information system (HIS), the clinical trial management system does not refer to a single system, but contains all relevant information systems involved in the clinical trials, such as electronic data capture system, study subject management system and regulatory data tabulation system, etc. In a broader definition, the trial application and management system of Institutional Review Board (IRB) can also be incorporated into the implementation process. The standardization of electronic clinical trial data will become the future development trend, which can ensure the quality of test data and accelerate the process of data integration analysis.
The Clinical Data Interchange Standards Consortium (CDISC) is an international standards development organization. Its main task is to establish a series of clinical research data collection, exchange, submission and archiving standards, including such as Clinical Data Acquisition Standards Harmonization, (CDASH), Study Data Tabulation Model (SDTM), the Standard for Exchange of Nonclinical Data (SEND), and the Analytical Data Model (ADM), which covering the entire clinical trial process.
For an example, in the drug permit license application, it will require applicant to fill the necessary information in a standard form. However, most of applicants may neglect parts of detailed data; It will not only take a lot of time and manpower to repeat supplement experiment, but is also possible to find some incomplete information needed for the regulatory review. For the companies, each time extension may generate additional costs and reduce revenue. Therefore, why we do not consider an experiment according to the standard at the beginning of the trial, meaning the stage of “design”, and an information system can be introduced to lead the researchers in collecting structured information that would avoid missing data, so as to increase the administrative efficiency.
CDISC has developed the Protocol Representation Model (PRM) for clinical trial design and planning, which is refers to the Good Clinical Practice (GCP) guideline, to suggest project content that should be included in the study plan. In addition to standardizing the contents of the study protocol, the file format for the study protocol is also regulated. With the practice of consistency, it is possible to increase the interoperability of the study protocol, so as to achieve the purpose and convenience of the secondary use of the data.
After completing a study protocol, the Institutional Review Board (IRB) will review whether the test design conform ethical, and the statistical examination will confirm the test assessment and the appropriateness according to ethics and statistics regulation.
End of the above reexaminations, the investigators had to execute clinical trials and to collect information from subjects. In the implementation of clinical trials, GCP needs to be followed during the trial. In addition to constantly check the information content is correct, but also to report the test bias and serious adverse events. Auditing and inspection is also needed to ensure the compliance with the provisions of the implementation plan. When the clinical trial is completed, if the drug is intended to be listed, the study protocol and the clinical data of the subject, etc., shall be submitted to the regulatory authority electronically in standard format.
The above states show that the data of a study protocol is constantly used in each stage of the trial. However, the current study protocol belongs a text file, and many of the research information may be scattered throughout the narrative of different paragraphs, it is difficult to be checked by a common system, such as verifying the completeness of the required information. If any information being lost or is incorrect, the drug permit license application will be required to continually supplement the information, and the experimental data is also needed to be complied with regulations.
Accordingly, the present invention has been used to informative and systematize the workflow of experienced large clinical trial companies through information technology, so as to reduce the burden of designing new trials. The object of the present invention can be used to design the steps of experimental and provide a standardize application form according to the international standard regulation through the system, further to establish the inspection mechanism for forming a complete process.
The present invention provides a method for producing a standard-compliant application document, which comprises:
(a) inputting a plural of standard specifications into a rule validation engine to establish a plural of validation rules, wherein the standard specification is plain text document;
(b) designing a plural of fields through a study protocol design system based on the validation rules, and submitting the plural of filled fields to the rule validation engine to check whether they meet the validation rules; the step (c) is carried out if the plural of fields meet the validation rules, and the study protocol design system would show an error field if the plural of fields do not meet the validation rules;
(c) outputting a study protocol from the study protocol design system;
(d) submitting the study protocol by an institutional review board (IRB) review system or a statistical review system to verify whether the study protocol meets an ethics and statistics regulation; the step (e) is carried out if the study protocol meets the ethics regulation and statistics methodology, and the study protocol design system would show a rejection if the study protocol do not meet the ethics regulation and statistics methodology;
(e) outputting an approved study protocol from the IRB review system or the statistical review system, and transmitting the approved study protocol into a data tabulation system and a clinical trial management system for collecting a plural of test results in different stages; and
(f) submitting the plural of test results collected from the clinical trial management system to the data tabulation system, and the rule validation engine will verify whether the test results meet the validation rules; the data tabulation system would output the standard-compliant application document if the test results meet the validation rules, otherwise the data tabulation system would show the error fields of the collected test results if the test results do not meet the validation rules.
The present invention can be applied to the clinical trial design and management system, the information system of the contract research organization (CRO), etc., which can support designing the clinical trial protocols under the regulation of Good Clinical Practice (GCP).
For clarity of disclosure, and not by way of limitation, the detailed description of the invention is divided into the subsections that follow. The present invention provides merely an example of the different types of functional arrangements that may be employed to implement the operation in the various components of a system, such as a computer connected to a detector, a multiprocessor computing device, and so forth.
The method execution steps of the present invention may include application specific software which may store in any portion or component of the memory including, such as random access memory (RAM), read-only memory (ROM), hard drive, solid-state drive, magneto optical (MO), IC chip, USB flash drive, memory card, optical disc such as compact disc (CD) or digital versatile disc (DVD), floppy disk, magnetic tape, or other memory components.

In step S105, the study protocol design system 13 outputs study protocol 14 after be completed filling. During this step, the study protocol 14 is designed under the Operational Data Model (ODM)/Study Trial Modulation (SDM) format of CDISC standard, and its contents should contain at least one protocol data, an experimental design, a schedule of activities and a case report form.
In one embodiment of the present invention, the content of the protocol information includes the purpose of the trial, the eligibility criteria of the subject, the intended test effect, the possible injury and the manner of treatment, etc. Besides, the experimental design includes the number of subjects, the grouping method, the randomization method, the experimental intervention design, etc. Wherein the schedule of activities includes schedule of the subject to be tested, measured, interviewed, tracked and other test evaluated in the program etc. In addition, the case report form includes the test data of subjects, basic demographic data, past medical history, may also include, but not limited to, questionnaires, scales, vital signs, or laboratory tests.
According to
Furthermore, in steps S107 and S109, the study protocol 14 is submitted to an IRB review system 15 or a statistical review system 16 to validate whether the study protocol 14 meet the ethics and statistics regulation. Then, the step S111 is performed if the study protocol 14 is allowed; otherwise, the rejection with reasons is showed if the study protocol 14 does not meet the ethics and statistics regulation. The study protocol 14 can be revised and modified for several times according to the review result until there is no error in the study protocol. In step S111, after completion of the review, the study protocol design system 13 will generate the approved study protocol 17.
Preferably, the approved study protocol 17 is imported into a clinical trial management system 18 in step S113. The test subjects should follow the design of approved study protocol 17 and set up the schedule. It does not only remind stages should be done, but also assist the user to collect the experiment data.
In step S115, the approved study protocol 17 is also imported to the data tabulation system 19. After completing the experiment, the test result would be export from the clinical trial management system 18 to the data tabulation system 19 in step S118. Then, the data tabulation system 19 is further to develop the collected data into the electronic case report form (eCRF) according to the approved study protocol 17.
Furthermore, in step S117, whenever the user has filled in the test result of each time period, the rule validation engine will verify the plural of test results whether meet the validation rules. The data tabulation system 19 would output the electronic case report form (eCRF), which includes the study protocol, the trial data, the CRF and the analysis result, if the test results meet the validation rule; otherwise, the data tabulation system 19 would show the error fields of the collected test results if the test results do not meet the validation rule. Therefore, the eCRF may follow the requirement of relation license application, such as drug permit license or permit for manufacturing etc,
The previous protocol design system requires the user to transform the clinical trial data into a standard-compliant document in accordance with the experience, and each time the different protocols are to be redesigned. The present invention designs a set of writing process based on the international clinical research organization specifications, and the text of the CDISC guidelines is built in the fields of the form, as an example prompted to help the protocol to be met the standard. In addition, the present invention facilitates the user to establish the rules to be checked by the users themselves, and to introduce the FDA guidance, to classify the rules according to the different stages, to establish the rules to be checked, to check at different stages so as to achieve immediate inspection, so as to reduce the probability of errors.
The electronic clinical trial protocol designed by the present invention can be imported into an electronic IRB review system, to review the process of experiment whether is based on ethics and statistics regulation by an independent organization, and may be further linked to a clinical trial electronic data acquisition (EDC) system. (Such as the number of subjects, assignments, visits, etc.) The collection and management of the clinical data of the subjects is carried out in the EDC system.
