SUPPLEMENTARY INFORMATION: I. Background FDA is announcing the availability of a draft guidance for industry entitled ``Adaptive Designs for Clinical Trials of Drugs and Biologics.'' This document provides guidance to sponsors and applicants submitting INDs, NDAs, BLAs, or supplemental applications on the appropriate use of adaptive designs [[Page 49401]] for clinical trials to provide evidence of the effectiveness and safety of a drug or biologic. The guidance describes the basic principles for designing, conducting, and reporting the results from an adaptive clinical trial. The guidance also advises sponsors on the types of information FDA needs to evaluate the results from clinical trials with adaptive designs, including Bayesian adaptive designs and complex designs that rely on computer simulations for their design. This guidance meets FDA's performance commitment under PDUFA (Prescription Drug User Fee Act) VI to publish draft guidance on complex adaptive (including Bayesian adaptive) trial designs by the end of fiscal year 2018. The primary focus of this guidance is on adaptive designs for clinical trials intended to support the effectiveness and safety of drugs or biologics. The concepts discussed are also useful for early phase or exploratory clinical trials as well as trials conducted to satisfy postmarketing commitments or requirements. The draft guidance will replace the 2010 draft guidance for industry entitled ``Adaptive Design Clinical Trials for Drugs and Biologics.'' This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on ``Adaptive Designs for Clinical Trials of Drugs and Biologics.'' It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations. This guidance is not subject to Executive Order 12866. II. Paperwork Reduction Act of 1995 Under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501- 3520), Federal Agencies must obtain approval from the Office of Management and Budget (OMB) for each collection of information that they conduct or sponsor. ``Collection of information'' is defined in 44 U.S.C. 3502(3) and 5 CFR 1320.3(c) and includes Agency requests or requirements that members of the public submit reports, keep records, or provide information to a third party. Section 3506(c)(2)(A) of the PRA (44 U.S.C. 3506(c)(2)(A)) requires Federal Agencies to provide a 60-day notice in the Federal Register for each proposed collection of information before submitting the collection to OMB for approval. To comply with this requirement, FDA is publishing this notice of the proposed collection of information set forth in this document. With respect to the collection of information associated with this draft guidance, FDA invites comments on the following topics: (1) Whether the proposed information collected is necessary for the proper performance of FDA's functions, including whether the information will have practical utility; (2) the accuracy of FDA's estimated burden of the proposed information collected, including the validity of the methodology and assumptions used; (3) ways to enhance the quality, utility, and clarity of the information collected; and (4) ways to minimize the burden of information collected on the respondents, including through the use of automated collection techniques, when appropriate, and other forms of information technology. The draft guidance discusses several collections of information that have been approved by OMB. For example, the draft guidance explains that sponsors who have questions about adaptive design elements in an early-phase exploratory trial should seek FDA feedback by either identifying specific questions in a submission containing the protocol or by requesting a meeting to discuss those questions. Discussion of the plans for an adaptive trial can be the basis for requesting a Type C meeting. Regulatory mechanisms for obtaining formal, substantive feedback from FDA on clinical trials may also include end-of-phase 2 meetings. The draft guidance also recommends that special protocol assessments (given the 45-day response timeline) are submitted for trials with complex adaptive designs only if there has been extensive previous discussion between FDA and the sponsor regarding the proposed trial and design. The draft guidance explains that in their submissions, the sponsors should pre-specify the details of the adaptive design and provide justification that the chances of erroneous conclusions will be adequately controlled, estimation of treatment effects will be sufficiently reliable, and trial integrity will be appropriately maintained. The draft guidance notes that the sponsor should advise FDA during the course of a trial of any proposed changes to the trial design (usually through protocol amendments), and that FDA may request that the sponsor submit minutes from open sessions of a monitoring committee during an ongoing trial. FDA has OMB approval under the PRA for the submission of INDs, including protocol amendments and information amendments, in 21 CFR part 312, subpart B, and sponsors may request comment and advice on an IND as well as request meetings with FDA under subpart C (OMB control number 0910-0014). In addition, the following collections of information that have been approved by OMB would cover other submissions discussed in the draft guidance: Guidance for industry on formal meetings with sponsors and applicants for PDUFA products (OMB control number 0910-0429); Guidance for Industry on special protocol assessment (OMB control number 0910-0470); Guidance for industry on clinical trial data monitoring committees (OMB control number 0910-0581); Guidance for industry on oversight of clinical investigations (OMB control number 0910-0733); International Council for Harmonization guidance for industry ``E6(R2) Good Clinical Practice'' (OMB control number 0910- 0843); Protection of Human Subjects: Informed Consent; Institutional Review Boards (21 CFR parts 50 and 56) (OMB control number 0910-0755); Institutional Review Boards (21 CFR 56.115) (OMB control number 0910-0130); and Requirements on Content and Format of Labeling for Human Prescription Drug and Biological Products (OMB control number 0910- 0572). In addition, the submission of NDAs, including 21 CFR 314.50(d)(5) (clinical data section) and (d)(6) (statistical section), has been approved under OMB control number 0910-0001. The submission of BLAs and their supplements has been approved under OMB control number 0910-0338. The draft guidance also requests the submission of information that has not been approved by OMB under the PRA. In section VIII.B, the draft guidance states that the documented plan for a clinical trial with a proposed adaptive design should include the information described below. The information could be included in the clinical trial protocol and/or in separate documents, such as a statistical analysis plan, a data monitoring committee (DMC) charter, or an adaptation committee charter. Although different types of information might be included in different documents, all important information described below should be submitted to FDA during the design stage so that FDA has sufficient time to provide feedback prior to initiation of the clinical trial: A rationale for the selected design; A detailed description of the monitoring and adaptation plan, including the anticipated number and [[Page 49402]] timing of interim analyses, the specific aspects of the design that may be modified, and the specific rule that will be used to make adaptation decisions; Information on the roles of the bodies responsible for implementing the adaptive design, such as the DMC and/or the dedicated adaptation committee; Pre-specification of the statistical methods that will be used to produce interim results and guide adaptation decisions, and to carry out hypothesis tests, estimate treatment effects, and estimate uncertainty in treatment effect estimates at the end of the trial; Evaluation and discussion of the design operating characteristics; When simulations are the primary or sole technique for evaluating trial operating characteristics, a detailed simulation report should be submitted, including: [cir] An overall description of the trial design; [cir] Example trials, in which a small number of hypothetical trials are described with different conclusions, such as a positive trial with the original sample size, a trial stopped for futility after the first interim look, a positive trial after increasing the sample size; [cir] A description of the set of parameter configurations used for the simulation scenarios, including a justification of the adequacy of the choices; [cir] Simulation results detailing the estimated Type I error probability and power under the various scenarios; [cir] Simulation code that is readable and adequately commented and should include the random seeds used to generate the simulation results; [cir] A summary providing overall conclusions. A comprehensive written data access plan defining how trial integrity will be maintained in the presence of the planned adaptations. This documentation should include the following information: (1) The personnel who will perform the interim analyses; (2) the personnel who will have access to interim results; (3) how that access will be controlled; (4) how adaptive decisions will be made; and (5) what type of information will be disseminated following adaptive decisions, and to whom it will be disseminated. The data access plan should describe what information, under what circumstances, is permitted to be passed to the sponsor or investigators. In addition, it is recommended that sponsors establish procedures to evaluate compliance with the data access plan and to document all interim meetings of the committee tasked with making adaptation decisions, i.e., the DMC or other adaptation committee (e.g., with written minutes describing what was reviewed, discussed, and decided). In section VIII.C, the draft guidance states that a marketing application to FDA that relies on a trial with an adaptive design should include, in addition to the typical content of that marketing application, sufficient information and documentation to allow FDA to thoroughly review the results, including: All prospective plans, any relevant committee charters (e.g., the DMC or adaptation committee charter), and any supporting documentation (e.g., literature references, programming code, simulation report); Information on compliance with the planned adaptation rule and with the procedures outlined in the data access plan to maintain trial integrity; Records of deliberations and participants for any interim discussions by any committees involved in the adaptive process; Results of the interim analyses used for the adaptation decisions; Appropriate reporting of the adaptive design and trial results in the proposed package insert. For example, the trial summary should describe the adaptive design utilized. In addition, treatment effect estimates should appropriately take the design into account, or if na[iuml]ve estimates such as unadjusted sample means are used, the extent of bias should be evaluated and estimates should be presented with appropriate cautions regarding their interpretation. Based on our review of INDs, NDAs, BLAs, and supplemental applications for the use of adaptive designs for clinical trials to provide evidence of effectiveness and safety, we estimate that approximately 40 sponsors or applicants (``number of respondents'' in table 1, row 1) will prepare approximately 240 documented plans for clinical trials containing a proposed adaptive design and analysis plan and will submit this information to FDA in a clinical trial protocol and/or in separate documents such as a statistical analysis plan, a DMC charter, or an adaptation committee charter (``total annual responses'' in table 1, row 1), and that preparing and submitting this information will take approximately 50 hours per sponsor or applicant (``average burden per response'' in table 1, row 1). In addition, we estimate that approximately 15 sponsors or applicants (``number of respondents'' in table 1, row 2) will prepare and submit to FDA approximately 20 marketing applications that rely on a trial with an adaptive design (``total annual responses'' in table 1, row 2), and that preparing and submitting this information will take approximately 50 hours per sponsor or applicant (``average burden per response'' in table 1, row 2). FDA estimates the burden of this collection of information as follows: Table 1--Estimated Annual Reporting Burden \1\ ---------------------------------------------------------------------------------------------------------------- Guidance on adaptive designs for Number of Average clinical trials of drugs and Number of responses per Total annual burden per Total hours biologics respondents respondent responses response ---------------------------------------------------------------------------------------------------------------- Clinical trial protocols and 40 6 240 50 12,000 related submissions to FDA with an adaptive design and analysis plan should contain the information in section VIII.B..
