Peloton Therapeutics, Inc. announced the initiation of patient dosing in a Phase 2 study of PT2385, the Company’s investigational first-in-class small molecule drug targeting hypoxia-inducible factor 2a (HIF-2a), for patients with von Hippel-Lindau (VHL) disease-associated kidney cancer. The primary objective of the study is to assess the overall response rate (ORR) of VHL disease-associated clear cell renal cell carcinoma (ccRCC) tumors in untreated VHL patients who received PT2385. The study is being conducted in collaboration with the National Cancer Institute (NCI). PT2385 is a selective, orally active agent that blocks HIF-2a with potent anti-cancer activity in preclinical models of ccRCC. This open-label Phase 2 study will evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamics of PT2385 in patients with VHL disease who have at least one measurable VHL disease-associated ccRCC tumor (as defined by RECIST 1.1). PT2385 will be administered orally and treatment will be continuous unless there is disease progression. Changes in VHL disease-associated non-ccRCC lesions will also be evaluated.
