Item 8.01 Other Events.
On December 10, 2024, Sutro Biopharma, Inc. (the “Company”) announced the selected dose from the dose-optimization portion (Part 1) of REFRαME-O1, the registration-directed trial of luveltamab tazevibulin (“luvelta”), a novel folate receptor-α (FolRα) targeting antibody drug conjugate (“ADC”), in platinum-resistant ovarian cancer (“PROC”).
REFRαME-O1 (Part 1):
REFRαME-O1 (Part 1) evaluated luvelta in patients with PROC with low, medium, and high FRα expression levels. This includes patients with ≥25% Tumor Proportion Score (TPS), defined as at least 25% of tumor cells expressing FRα, at any staining intensity. In the dose-optimization (Part 1), patients were randomized 1:1 to a 5.2 mg/kg with prophylactic pegfilgrastim (G-CSF) for 2 cycles followed by 4.3 mg/kg for subsequent cycles (5.2 mg/kg group), or a 4.3 mg/kg dose of luvelta for all cycles (4.3 mg/kg group).
Topline Results from evaluable patients (5.2 mg/kg group; N = 25):
REFRαME-O1 (Part 2) Registrational Trial:
REFRαME-O1 (Part 2) is an ongoing global registrational trial for patients with PROC, evaluating a 5.2 mg/kg dose with prophylactic pegfilgrastim (G-CSF) for the first two cycles followed by a 4.3 mg/kg dose for subsequent cycles. Part 2 will enroll approximately 500 patients, randomized 1:1 to luvelta or investigators’ choice of chemotherapy.
