Does anyone else have any experience with Anti-kir or know more about it? Cindy September 29, 2013 at 11:55 am #62623 Catherine PooleKeymaster Blocking Kir is thought to activate another branch of the immune system and might complement other immune therapies. No results yet however, but promising. September 29, 2013 at 6:56 pm #62624 cindy5Participant The other question is: the ipi/anti-kir is a phase I, the ipi/nivolumab is a phase II…does that matter? September 29, 2013 at 7:16 pm #62625 Catherine PooleKeymaster Phase 1 means they are looking for toxicity and dosage, not a lot more is known. Phase II means they are beyond the dosaging phase.
