Clinical Trial Considerations To Support Accelerated Approval of 
Oncology Therapeutics; Draft Guidance for Industry; Availability

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a draft guidance for industry entitled ``Clinical 
Trial Considerations to Support Accelerated Approval of Oncology 
Therapeutics.'' The purpose of this guidance is to provide 
recommendations to sponsors of anti-cancer drugs or biological products 
on considerations for designing trials intended to support accelerated 
approval. The accelerated approval pathway is commonly used for 
approval of oncology drugs due to the serious and life-threatening 
nature of cancer. Although single-arm trials have been commonly used to 
support accelerated approval, a randomized controlled trial is the 
preferred approach as it provides a more robust efficacy and safety 
assessment and allows for direct comparisons to an available therapy. 
This guidance describes considerations for designing, conducting, and 
analyzing data for trials intended to support accelerated approvals of 
oncology therapeutics.

DATES: Submit either electronic or written comments on the draft 
guidance by May 26, 2023 to ensure that the Agency considers your 
comment on this draft guidance before it begins work on the final 
version of the guidance.

ADDRESSES: You may submit comments on any guidance at any time as 
follows:

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a draft guidance for industry 
entitled ``Clinical Trial Considerations to Support Accelerated 
Approval of Oncology Therapeutics.'' The purpose of this guidance is to 
provide recommendations to sponsors of anti-cancer drugs or biological 
products on considerations for designing trials intended to support 
accelerated approval. The accelerated approval pathway is commonly used 
for approval of oncology drugs in part due to the serious and life-
threatening nature of cancer and because of available surrogate or 
intermediate clinical endpoints considered reasonably likely to predict 
clinical benefit. Single-arm trial designs and response rate endpoints 
(with duration of response as supportive) have most commonly been used 
in oncology because response rate is a marker of drug activity since 
malignant tumors do not typically regress on their own, and response 
rate can be interpreted in single-arm trials for monotherapy drug 
regimens. However, there are limitations to the use of single-arm 
trials in support of accelerated approval, including but not limited 
to: small safety datasets, low magnitude response rates that may not be 
reasonably likely to predict clinical benefit, and the inability to 
establish differential contribution of effect for combination regimens. 
Additionally, the reliance on cross-trial comparisons to historical 
trials to assess whether the observed treatment effect represents an 
improvement over available therapy is challenging. These limitations 
add uncertainty to the assessment of the safety and/or effectiveness of 
a drug such that accelerated approval based on a single-arm trial may 
not be justified in a given clinical setting.
    Given the limitations of single-arm trials, FDA considers a 
randomized controlled trial to be the most appropriate trial design to 
support accelerated approval of oncology drugs. When properly designed 
and executed, a randomized controlled trial provides a more robust 
efficacy and safety assessment and allows for direct comparisons to a 
concurrent control arm. Sponsors can, as appropriate, elect to conduct 
a single randomized controlled trial to support an accelerated approval 
and to verify clinical benefit (i.e., follow the ``one-trial'' 
approach), or they can conduct separate trials--one to support the 
accelerated approval and another, a confirmatory trial, to verify 
clinical benefit. The ``one-trial'' approach maintains efficiency in 
drug development by providing early access to an investigational drug 
using the accelerated approval pathway, while ensuring that a 
postmarketing trial is fully accrued and well underway to verify longer 
term benefit in a timely fashion.
    This guidance describes considerations for designing, conducting, 
and analyzing data for trials intended to support accelerated approval 
of oncology drugs. Specifically, the guidance provides recommendations 
addressing the design, conduct, and analyses of data for either two 
separate randomized controlled trials or for using the ``one-trial'' 
approach for accelerated approval. The guidance also provides 
recommendations for designing, conducting, and analyzing data from a 
single-arm trial intended to support accelerated approval (when 
appropriate), and the considerations for determining whether the data 
may be adequate for this purpose. Regardless of the approach under 
consideration, FDA recommends early discussion before study initiation 
and during trials, as appropriate.
    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 ``Clinical 
Trial Considerations to Support Accelerated Approval of Oncology 
Therapeutics.'' 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.

II. Paperwork Reduction Act of 1995

    While this guidance contains no collection of information, it does 
refer to previously approved FDA collections of information. Therefore, 
clearance by the Office of Management and Budget (OMB) under the 
Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501-3521) is not 
required for this guidance. The previously approved collections of 
information are subject to review by OMB under the PRA. The collections 
of information in 21 CFR part 312 have been approved under OMB control 
number 0910-0014; the collections of information in 21 CFR part 314 
have been approved under OMB control number 0910-0001; and the 
collections of information in 21 CFR part 601 have been approved under 
OMB control number 0910-0338.
