Dunno if this info helps but I saw my local doc yesterday and was suprised to hear some of his patients he sent to mayo have been turned away from Merck's EAP PD1 NCT02083484. He said it is because they were in wheel chairs.
As we see on clinicaltrials.gov this does require a 0 or 1 for the Eastern Cooperative Oncology Group Performance. I guess I never noticed that before eventhough I had read it several times. So if you are trying for this trial and are in a wheel chair I dunno what to say about it other than my own story. Back in February the docs were saying I was a hairs breath from being paralyzed. They said anyone else with that much spinal cord damage would already be paralyzed. So yeah I was in a wheel chair some. But I got some good radiation to the tumor that was pressing on my spinal cord that shrank it by about half so now I walk my 2 miles a day and get this PD1 just fine. Also before the radiation they gave me steroids that a scan in preparation for the radiation proved in the matter of a week or so provided more room in the spinal canal for the cord thus making walking much easier. So I dunno what else to say but I hope everyone who needs this medicine gets it somehow.
