Evaluating Cancer Drugs in Patients With Central Nervous System 
Metastases; Guidance for Industry; Availability

AGENCY: Food and Drug Administration, HHS.

[[Page 35306]]

ACTION: Notice of availability.

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

SUMMARY: The Food and Drug Administration (FDA or Agency) is announcing 
the availability of a final guidance entitled ``Evaluating Cancer Drugs 
in Patients with Central Nervous System Metastases; Guidance for 
Industry.'' The guidance document provides recommendations regarding 
the design of clinical trials of drugs and biological products 
regulated by the Center for Drug Evaluation and Research (CDER) and the 
Center for Biologics Evaluation and Research (CBER) that are intended 
to support product labeling describing the antitumor activity in 
patients with central nervous system (CNS) metastases from solid tumors 
originating outside the CNS. The guidance includes study design 
recommendations regarding the patient population, available therapy, 
prior therapies, assessment of CNS disease, study endpoints, and 
leptomeningeal disease. The guidance announced in this notice finalizes 
the draft guidance of the same title dated August 2020.

DATES: The announcement of the guidance is published in the Federal 
Register on July 2, 2021.

SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a document entitled 
``Evaluating Cancer Drugs in Patients with Central Nervous System 
Metastases.'' This guidance provides recommendations for sponsors 
designing clinical trials of drugs and biological products regulated by 
CDER and CBER that are intended to support product labeling describing 
the antitumor activity in patients with CNS metastases from solid 
tumors originating outside the CNS. Specifically, the guidance includes 
recommendations regarding the patient population, available therapy, 
prior therapies, assessment of CNS disease, study endpoints, and 
leptomeningeal disease. The guidance describes that CNS metastases 
should be evaluated in the context of the entire disease burden and 
discusses how treatment effects may be described in drug labeling. The 
recommendations pertain to clinical trials for systemic anticancer 
drugs where patients with CNS metastases are included in the study 
population. These recommendations are also applicable to

[[Page 35307]]

trials conducted exclusively in patients with CNS metastases.
    CNS metastases are associated with significant morbidity and 
mortality and development of therapeutic products for patients with CNS 
metastases is needed. FDA has participated in efforts to facilitate 
drug development for patients with CNS metastases, including a March 
2019 ``Workshop on Product Development for CNS Metastases.'' 
Stakeholders at this meeting stated there is a need for further FDA 
guidance on specific topics, including identifying optimal study 
endpoints. Study design challenges for CNS metastases include 
uncertainty regarding optimal endpoints, lack of standardized response 
assessments, understanding how CNS metastases are evaluated in the 
context of the entire burden of metastatic disease to characterize a 
drug's potential benefit (e.g., timing of CNS radiographic assessments 
relative to other sites of metastases), and interpreting radiographic 
response in the setting of recent radiation therapy or surgery. This 
guidance is intended to provide recommendations on these study design 
challenges.
    In the Federal Register of August 27, 2020 (85 FR 53007), FDA 
announced the availability of the draft guidance ``Evaluating Cancer 
Drugs in Patients with Central Nervous System Metastases'' dated August 
2020. FDA received several comments on the draft guidance and those 
comments were considered as the guidance was finalized. A summary of 
changes includes: Clarification on the number of stratification factors 
the protocol should specify in order to minimize bias, confirmation of 
the version of Response Evaluation Criteria in Solid Tumours (RECIST) 
that should be referred to when evaluating CNS disease, clarification 
that both CNS and systematic duration of response should be captured 
and the addition of a 6-month timepoint, and the addition of 
progression-free survival in patients with brain metastasis as another 
measurement to be reported when CNS is a common metastatic site. In 
addition, editorial changes were made to improve clarity. The guidance 
announced in this notice finalizes the draft guidance dated August 27, 
2020.
    This guidance is being issued consistent with FDA's good guidance 
practices regulation (21 CFR 10.115). The guidance represents the 
current thinking of FDA on ``Evaluating Cancer Drugs in Patients with 
Central Nervous System Metastases.'' 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; the collections 
of information in 21 CFR part 601 have been approved under 0910-0338; 
and the collections of information in 21 CFR 201.56 and 201.57 have 
been approved under OMB control number 0910-0572.
