Pulmonary Hypertension
Conditions
Brief summary
mTOR activation has been shown to be relevant in the development and progression of pulmonary hypertension. Inhibition of mTOR has been shown to reverse or regress pulmonary hypertension in animal models. nab-Sirolimus (also known as ABI-009, nab-rapamycin) is an albumin-bound mTOR inhibitor with improved penetration in lung tissue.
Detailed description
nab-Sirolimus, an mTOR inhibitor, is a novel formulation of albumin-bound sirolimus nanoparticles and has produced encouraging results in oncology at doses up to 100 mg/m2 given once weekly IV. This study is aimed to determine the optimal clinial dose of once weekly IV nab-sirolimus in patients with PAH and safety of 16 weeks of therapy (Phase 1, Dose finding Safety Part) followed optionally by up to 32 weeks of therapy (Extension Part).
