Official title
A First-in-Human, Open-label, Phase 1/2 Clinical Trial to Assess the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of HMBD-501 in Patients With Advanced-Stage, Relapsed/Refractory HER3-Expressing Solid Tumors
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is a Phase 1/2, first-in-human, open-label, clinical trial to assess the safety, tolerability, pharmacokinetics and preliminary efficacy of HMBD-501 in patients with advanced-stage, relapsed and/or refractory human epidermal growth factor receptor 3 (HER3)-expressing solid tumors. The study consists of 2 phases: a dose escalation phase (Phase 1) and a dose expansion phase (Phase 2). The primary objectives of Phase 1 are to characterize the overall safety and tolerability profile of increasing doses of HMBD-501 in patients with advanced-stage solid tumors and identify the recommended Phase 2 dose (RP2D) of ENV-501. During Phase 1, successive cohorts of patients will receive escalating doses of HMBD-501. The results of the dose escalation will determine the RP2D and dosing schedule of HMBD-501 to be administered in the Phase 2 part of the study. The primary objective of Phase 2 is to evaluate the preliminary clinical efficacy of HMBD-501 in dose expansion cohorts.
