Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NA

Intervention Model

SINGLE_GROUP

Eligible patients will be enrolled and treated with intravenous HDP-101 every 3 weeks. In Phase 1 dose-escalation part from Cohort 6 additional treatment arms are introduced for dose-optimization purposes with dosing every 3 weeks, split dosing weekly or split dosing in the first cycle on Day1 and Day8.

A Bayesian logistic regression model will be used to guide dose-escalation during Phase 1 and select the best dose for the Phase 2a of the study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

HDP-101

Participants will receive HDP-101 intravenously in a 21 day cycle until disease progression, intolerable toxicity, Investigator's discretion or patient withdrawal.

During the phase 1 tolerability of different dose levels will be evaluated. During the phase 2a dose expansion part the recommended phase 2 dose (RP2D) of HDP-101 will be administered.
