Official title
Single-Center Randomized Controlled Phase II Study of Safety and Efficacy of FK-506 (Tacrolimus) in Pulmonary Arterial Hypertension
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Mutations in bone morphogenetic protein receptor 2 (BMPR2) are present in \>80% of familial and \~20% of sporadic pulmonary arterial hypertension (PAH) patients. Furthermore dysfunctional BMP signaling is a general feature of pulmonary hypertension even in non-familial PAH. We therefore hypothesized that increasing BMP signaling might prevent and reverse the disease. We screened \> 3500 FDA approved drugs for their propensity to increase BMP signaling and found FK506 (Tacrolimus) to be a strong activator of BMP signaling. Tacrolimus restored normal function of pulmonary artery endothelial cells, prevented and reversed experimental PAH in mice and rats. Given that Tacrolimus is already FDA approved with a known side-effect profile, it is an ideal candidate drug to use in patients with pulmonary arterial hypertension. The aims of our trial are: 1. Establish the Safety of FK506 in patients with PAH. 2. Evaluate the Efficacy of FK506 in PAH 3. Identify ideal candidates for future FK506 phase III clinical trial.
