Right now most trials are closed for PD1. The IPI naïve (never had IPI/Yervoy) has a few recruiting. If you are interested, email me for locations: cpoole@melanomainternational.org
Also, the PDL with Braf/mek or mek only for braf negative folks is opening at various locations. The company has not gotten back to me after numerous contacts but you can look at the listing:
