Comments on Breakthrough Therapy Recission Draft

Share

Pharmaceutical Research and Manufacturers of America (PhRMA) is calling on FDA to identify the legal authority for rescinding breakthrough therapy designations (BTDs) as described in a draft guidance. Its comment letter also says the agency should (1) explicitly incorporate procedural details from relevant SOPPs (standard operating policies and procedures) and MAPPs (Manual of Policies and Procedures), and (2) clarify the examples on when it may, or may not, rescind a BTD.

Gilead says it supports FDA’s thinking on partnering with sponsors and clinical trial design, endpoint, and other evaluative data flexibility under BTDs based on new data that may arise during the clinical trial process. It asks that the agency further consider integrating any final version of the draft guidance with an existing guidance on expedited programs for serious conditions, include the process for sponsors to respond to an FDA request to rescind a BTD, and add an acknowledgment that sponsors may request that a BTD be rescinded.

The Cystic Fibrosis Foundation says it believes that an FDA policy of rescinding BTDs under an alternative drug provision “undermines the legitimate benefits of rapidly bringing multiple drug products for underserved conditions to market.” It says the agency should explicitly take varying patient response profiles and serious adverse events into account when determining whether to continue BTD in these situations.
