A Study to Assess Adverse Events and Change in Disease Activity of Oral ABBV-453 Alone or in Combination With Subcutaneous and/or Oral Antimyeloma Agents in Adult Participants With Multiple Myeloma (MM)
A Phase 1/2, Open-Label, Platform Study to Evaluate Safety and Efficacy of the BCL-2 Inhibitor Surzetoclax (ABBV-453) Given as Monotherapy or in Combination With Antimyeloma Regimens in Subjects With Multiple Myeloma
A Study to Assess Adverse Events and Change in Disease Activity of Oral ABBV-453 Alone or in Combination With Subcutaneous and/or Oral Antimyeloma Agents in Adult Participants With Multiple Myeloma (MM) (NCT06953960) is a Phase 1 / Phase 2 interventional studying Multiple Myeloma, sponsored by AbbVie. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.
About This Trial
Multiple myeloma (MM) is a plasma cell disease characterized by the growth of clonal plasma cells in the bone marrow. The purpose of this study is to assess the safety and change in disease activity of ABBV-453 in adult participants with relapsed/refractory (R/R) MM. Adverse events and change in disease activity will be assessed. ABBV-453 is an investigational drug being developed for the treatment of R/R MM. In Substudy 1 there will be a dose escalation phase where participants will receive various doses of ABBV-453 in combination with daratumumab + dexamethasone, to determine the best dose of ABBV-453. This will be followed by a dose expansion and selection phase where participants will receive 1 of 2 doses of ABBV-453 in combination with daratumumab + dexamethasone, or daratumumab + dexamethasone + pomalidomide (only during the expansion phase). In Substudy 2, there will be a dose escalation phase where participants will receive various doses of ABBV-453 alone. Approximately 130 adult participants with R/R MM will be enrolled in the study in approximately 40 sites worldwide. In Substudy 1 escalation phase, participants will receive oral ABBV-453 tablets in combination with subcutaneous (SC) daratumumab injections + oral dexamethasone tablets and in the expansion phase, will receive oral ABBV-453 tablets in combination with SC daratumumab injections + oral dexamethasone tablets or daratumumab injections + oral pomalidomide + oral dexamethasone tablets. In Substudy 2, Japanese participants will receive oral ABBV-453 tablets. The total study duration is approximately 4.5 years. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution. The effect of the treatment will be frequently checked by medical assessments, blood tests, and side effects.
What Stage of Research Is This?
Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Multiple Myeloma, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.
This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.
Target enrollment of 130 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Multiple Myeloma subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Bring the printable summary of this trial — including the NCT ID (NCT06953960), the sponsor (AbbVie), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.
Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

Who can participate in NCT06953960?
Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.
How do I contact the trial site for NCT06953960?
Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.
Is participating in a clinical trial safe?
Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
