February 13, 2025 updated by: Genentech, Inc.

A Phase Ib, Open-Label, Multicenter, Dose-Escalation Study to Evaluate the Safety and Pharmacokinetics of XMAB24306 in Combination With Daratumumab in Patients With Relapsed/Refractory Multiple Myeloma

This study will evaluate the safety, tolerability, pharmacokinetics, and activity of XmAb24306 in combination with a multiple myeloma (MM)-targeting monoclonal antibody capable of inducing antibody-dependent cellular toxicity (ADCC) in participants with relapsed or refractory (R/R) MM who have received a minimum of three prior treatments, including at least one immunomodulatory drug (IMiD), one proteasome inhibitor (PI), and one anti-CD38 monoclonal antibody.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  • Participants must have received a minimum of 3 prior lines of therapy, including at least one PI, one IMiD, and an anti-CD38 monoclonal antibody
  • Best response of stable disease or better with at least one prior anti-CD38 monoclonal antibody containing line of treatment

Exclusion Criteria:

  • Any anti-cancer therapy within 3 weeks prior to initiation of study treatment, with exceptions defined by the protocol
  • Prior allogeneic stem cell or solid organ transplantation

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
Time Frame

Time Frame: Up to approximately 3 years
Up to approximately 3 years

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
Time Frame
Serum concentration of XmAb24306
Time Frame: Baseline to approximately 3 years
