Pfizer is conducting a phase one, randomized, double-blind, placebo controlled human trial to evaluate the safety, tolerability, and pharmacokinetics of PF-06755347, a recombinant fragment crystallisable (rFc), in healthy adult male patients between 18-40 years of age. Male participants much have no evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing). Participants with a history of autoimmune disorders and other conditions that compromise or impair the immune system are also excluded from participating. It is hoped that this therapy could be used to treat ITP if tolerable and safe in healthy controls.
