REGULATORY CORNER

The new FDA draft guidance, Key Information and Facilitating Understanding in Informed Consent, (March 2024) provides some food for thought regarding the informed consent process and how we should organize our informed consents to best inform potential study participants about the studies we are conducting. I’ve recently read Patient H.M. (Luke Dittrich, 2016), about a patient with severe epilepsy who was treated with a lobotomy in an effort to reduce the seizures. While seizures remained severe, the procedure resulted in eliminating the patient’s ability to establish short-term memory and erased or jumbled most of the patient’s long-term memory. While it was noted that this particular patient did consent to the procedure, the book also chronicles stories of asylum patients with mental disorders who were given lobotomies without their or their legal representative’s prior consent. I am always both amazed and horrified when reminded that these types of research methods occurred in my lifetime. The processes we currently follow in generating informed consent forms (ICFs) for use in today’s clinical studies were not always standard procedure. Remembering this and understanding the importance of having each trial subject freely give consent, after being fully informed of the trial’s objectives, risks and benefits, is an interesting, important and relevant topic for consideration as we design and execute clinical studies.

I used to think of a Benefit Risk Assessment as part of a marketing application. However, FDA’s recent guidance, Benefit-Risk Assessment for New Drug and Biologic Products, published in October 2023, clearly highlights the role that Benefit-Risk Assessments play throughout the lifecycle of a product, not only at the time of New Drug Application (NDA) or Biologic Licensing Application (BLA) review.

In this blog, I will be referencing data in the public domain to compare and contrast the studies submitted to FDA to support label expansions for two marketed products and the similarities and differences in the FDA review and outcomes. By way of disclosure, PROMETRIKA has not worked on either of the two products discussed and all information presented is in the public domain (the October 5, 2023 Oncologic Drugs Advisory Committee (ODAC) FDA slides and ODAC vote for the first and the April 1, 2022 Clinical Review and Evaluation and Statistical Review for the second).
