If you would like to find out if you are eligible for any clinical trials that include new therapies for the treatment or prevention of PCP, there is an interactive web site run by ACRIA, the AIDS Community Research Initiative of America. Another useful service for finding clinical trials is AIDSinfo.nih.gov, a site run by the U.S. National Institutes of Health. They have "health information specialists" you can talk to at their toll-free number at 1-800-HIV-0440 (1-800-448-0440).
