PhaseBio will be responsible for all development, manufacturing and commercialization of PB6440. In preclinical studies completed to date, PB6440 was observed to be a highly potent and selective inhibitor of aldosterone synthase (CYP11B2) versus the closely-related steroid 11β-hydroxylase enzyme (CYP11B1). PB6440 demonstrated dose-dependent aldosterone reduction without a significant increase in 11-deoxycorticosterone or deoxycortisol in both rodent and primate models. The oral bioavailability and pharmacokinetic profiles appear suitable for once-daily dosing in humans. To date, no evidence of toxicity has been observed in either in vitro toxicity studies or in animal models, including primates. PhaseBio is planning to initiate clinical development of PB6440 pending the completion of nonclinical Investigational New Drug Application (“IND”)-enabling studies planned for 2020, which are expected to be followed by an IND filing and a first-in-human study in early 2021.
“Hypertension is one of the key risk factors for cardiovascular disease and has been linked to significant morbidity and mortality,” said
About PB6440
PB6440 is a highly selective aldosterone synthase inhibitor being developed for treatment-resistant hypertension. PB6440 modulates the renin-angiotensin-aldosterone system, which plays a critical role in regulation of systemic blood pressure. Despite the broad range of currently available antihypertensive therapies, approximately 10 million, or 20%, of drug-treated
