Judy….. Most major centers are involved in these studies. You might want to start with the treating physician, as he/she may be able to lead you to a center closest for participation. I believe that once approved for a different cancer, physicians will then use the “off label” and the pd-1 and anti pd-L1 pembrolizumab (lambrolizumab) drug are under investigation and are expected to be released by the end of this year.
From what I have learned the NIH is overrun with request, but Melinda’s study is recruiting:

The newest in the making are the n-of-1 trials (single patient trials) part of personalized medicine. But, I have little information on this.
