About a month ago..I applied for participation in the Merck phase 2 anti pd1 trial..I was disqualified due to having received two out of the four chemo options in a previous trial (but that’s another story). It is my understanding they had doubled the amount of available slots and have more than what they need in participants. People flocked to the Merck trial because of the cross over option..the only other pd1 option that I am aware of that’s ongoing at this time is the BMS phase 3..pd1 or chemo…no crossover. The Merck and BMS trials I was opting for were being held at NYU. There may be an outside chance they still have slots…it may be worth a try to call their trial dept.
