SUPPLEMENTARY INFORMATION:

I. Background

    FDA is announcing the availability of a final guidance for industry 
entitled ``Expansion Cohorts: Use in First-in-Human Clinical Trials to 
Expedite Development of Oncology Drugs and Biologics.'' The purpose of 
this guidance is to provide advice to sponsors regarding the design and 
conduct of FIH clinical trials intended to efficiently expedite the 
clinical development of oncology drugs, including biological products, 
through multiple expansion cohort trial designs. These are trial 
designs that employ multiple, concurrently accruing, subject cohorts, 
where individual cohorts assess different aspects of the safety, 
pharmacokinetics, and antitumor activity of the drug product. This 
guidance provides FDA's current thinking regarding (1) characteristics 
of drug products best suited for consideration for development under a 
multiple expansion cohort trial; (2) information to include in 
investigational new drug application submissions to support the use of 
individual cohorts; (3) when to interact with FDA on planning and 
conducting multiple expansion cohort trials; and (4) safeguards to 
protect subjects enrolled in FIH expansion cohort trials.
    This guidance finalizes the draft guidance of the same name issued 
August 13, 2018 (83 FR 40055). Changes made to the guidance took into 
consideration public comments received. Major changes from the draft to 
the final guidance include the following:
     Language added stating that designs other than Simon two-
stage (e.g., Bayesian statistical design) may be used to assess 
antitumor activity in a nonrandomized cohort to limit the number of 
subjects that could be exposed to a potentially ineffective drug.
     Statement added to indicate that in trials of limited 
sample size, a safety assessment committee could be a group within the 
sponsor's organization alone that is not otherwise involved in trial 
conduct or management or with external representation in lieu of an 
independent data monitoring committee.
     Language added to state that development of an age-
appropriate formulation may be necessary for pediatric populations.
     Minor changes added to various sections to clarify 
criteria for drug products suitable for investigation in clinical 
trials with FIH multiple expansion cohorts, the procedure for obtaining 
a risk assessment if an in vitro diagnostic will be used for patient 
management, and the information to be submitted to the FDA to support 
amendments to expand the protocol.
    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 ``Expansion Cohorts: Use in First-in-Human 
Clinical Trials to Expedite Development of Oncology 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.
