Study to Assess Safety of HDP-101 in Patients With Relapsed Refractory Multiple Myeloma

Официальное название

A Phase 1/2a, First-in-human Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Efficacy of HDP-101 in Patients With Plasma Cell Disorders Including Multiple Myeloma

Обзор

This study will assess the safety, tolerability, pharmacokinetics (PK) and the therapeutic potential of HDP-101 in patients with plasma cell disorders including multiple myeloma.

Подробное описание

The study will consists of two parts: a Part 1 dose escalation phase and a Part 2a expansion phase for safety, tolerability, PK, PD, and clinical activity testing. The study will enroll subjects with relapsed/refractory MM or other plasma cell disorders expressing BCMA. An adaptive 2-parameter Bayesian logistic regression model (BLRM) for dose-escalation with overdose control will be used in the dose-escalation phase for determination of the MTD or the RP2D. Dose-expansion phase of the study aims to collect preliminary evidence of antitumor activity and to confirm the safety of the HDP-101 as a monotherapy.
