Expanded Access [EXPANDED ACCESS =A process regulated by the Food and Drug Administration (FDA) that allows manufacturers to provide investigational new drugs to patients with serious diseases or conditions who cannot participate in a clinical trial.

1. This is good news. Anytime a drug that has a positive effect is available for more folks in need, that is a very good thing indeed.
2. In the pandemonium that has surrounded this announcement it is important to remember what studies show this drug can offer. In Merck's first Phase 1B study with this anti-PD1 product, once follow-up data was added, overall response rate was 41%, with 88% of patients who demonstrated partial or complete responses, showing no evidence of disease progression.
3. For what it is worth, Dr. Weber, who is currently running trials with both the BMS and Merck anti-PD1 drugs, feels that they will both pan out with approximately the same overall results.
1. Exclusions include - "history of life-threatening or severe immune-related adverse event" on prior immunotherapy. Who decides? Is an admission for colitis on ipi, though now recovered, considered a "severe immune-related adverse event"? Is ipi induced hypothyroidism?
2. I assume that "failed or progressed on standard of care systemic therapy including ipi" also includes IL2? other anti-PD1 products? (Various folks on the forums are saying that failing anti-PD1 products other than Merck's allow inclusion, though it is not clearly stated here.)
3. If BRAF positive, it seems that you must go ahead and use that option, then fail/progress in order to gain access to MK-3475. Would this be something I wanted to do first, if I had minimal disease burden? I don't know the answer to that. But, I think it would be a hard thing for me to decide.
4. Since not explicitly stated, must one have failed on ALL of the above? If you have one of these "systemic therapies" left untried, must you do, say...IL2, before you can gain access? Even though you failed ipi and BRAF?
5. An additional exclusion, is if you are "eligible for an accessible MK-3475 clinical study." Does this mean that if there were a study with MK-3475 vs say...dacarbazine...and you got the dacarbazine arm....you are stuck with that and ineligible for expanded access? What is accessible? If there is an expanded access option within 30 minutes of your home, but an MK-3475 trial slot open several hours away....must you take the trial slot?
6. Who will pay for the drug? I am not saying there will be a charge, but it doesn't say there will NOT be, either. The company could petition the FDA for the ability to charge the patient. Additionally, will facilities providing the drug charge the patient? Again, they could petition the FDA as well. You can check the links below for additional info.
Hopefully the answers to these questions will be clarified very soon and patients with few remaining options will be given another viable solution!!!
Fingers crossed - c
