Hello from the Post-Trial Responsibilities conference! I will be live blogging session 2: where speakers will be providing important perspectives on PTA. Barbra Bierer is monitoring the discussion.
We started with Richard Klein calling in from FDA:
Richard is talking about post-trial responsibilities. He points out that there is a justice issue here with ensuring access to health care and up to date interventions. He points out that while the FDA can encourage Post-Trial Access (PTA), it has no authority to require or ensure it. He points to moral authority, rather than legal. Foreign trials, however, are a different story, as the FDA has sway over protocol applications that are submitted in the US. Richard begins highlighting some specific considerations for protocol drafters and IRBs: particularly focusing on determining monitoring plans, as well as figuring out financial responsibilities for the provision of PTA.
He moves on to highlight that there is more of a moral obligation than a legal obligation. FDA is supportive of the provision of PTA. He believes that enthusiasm must be tempered, as there are situations when PTA is not appropriate. These include studies that have significant safety concerns, studies of bio-markers as well as validation studies that do not specifically examine safety and effectiveness. There are also situations where PTA is simply not feasible, particularly if additional drugs do not exist (one thinks of the recent Ebola treatment), if there is insufficient safety data, or if there is no practical capacity or resources to provide safety monitoring. We must also be aware of financial limitations, especially for start-up biotech firms that might not have deep pockets.
