Advantages and Challenges with Multiple Expansion Cohort Design in Oncology Studies

Food and Drug Administration (FDA) has provided a new type of study design for conducting Phase I first-in-human oncology studies.

This design, known as a multiple expansion cohort (MEC) design, allows the sponsor to have multiple experimental groups in a single study simultaneously.

The FDA guidelines explain that objective of these specially designed trials can be the assessment of anti-tumor activity in a setting specific to the disease, finding safe dose in special populations, evaluating alternative schedules or doses etc.

Each group has a different objective as explained above, therefore, multiple objectives can be achieved in a single phase.

This helps in better resource management as a sponsor can decide whether to proceed or to discontinue the drug development based on the Phase I study.

Multiple expansion cohort designs enable the investigator to know early that in which population the drug is working effectively.
