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

July 22, 2024 updated by: Heidelberg Pharma AG

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

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Time Frame: Up to Day 21 (from first dose)
Up to Day 21 (from first dose)
Objective response rate (ORR)
Time Frame: Through study completion, an average of 1 year
Proportion of enrolled subjects who achieve a partial response (PR) or better, i.e. stringent complete response (sCR), complete response (CR), very good partial response (VGPR) and PR, according to the IMWG criteria.
Through study completion, an average of 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Assess the safety and tolerability of HDP-101
Time Frame: Through study completion, an average of 1 year
Number of patients with serious and non-serious adverse events grouped by system organ class and preferred terms based on Common Terminology Criteria for Adverse Events (CTCAE v 5.0) classification.
Through study completion, an average of 1 year
