A Study to Assess Change in Disease Activity and Adverse Events (AE)s in Adult Participants With Multiple Myeloma Receiving Etentamig (ABBV-383) as an Intravenous (IV) Infusion Alone or in Combination With Oral, IV, Subcutaneous Daratumumab; Lenalidomide; Dexamethasone; Carfilzomib
What this study is about
Multiple myeloma (MM) is a cancer of the blood's plasma cells. The cancer is typically found in the bones and bone marrow (the spongy tissue inside of the bones) and can cause bone pain, fractures, infections, weaker bones, and kidney failure. Treatments are available, but MM can come back (relapsed) or may not get better (refractory) with treatment.

Multiple myeloma (MM) is a cancer of the blood's plasma cells. The cancer is typically found in the bones and bone marrow (the spongy tissue inside of the bones) and can cause bone pain, fractures, infections, weaker bones, and kidney failure. Treatments are available, but MM can come back (relapsed) or may not get better (refractory) with treatment. This is a study to determine the safety, efficacy, and pharmacokinetics of Etentamig in adult participants with MM.

Primary outcome measures
Number of Participants with Adverse Events (AE)s
Time frame: Up to Approximately 130 Months
An adverse event is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment.
Substudy 1: Dose-Limiting Toxicity (DLT) of Etentamig + Daratumumab and Lenalidomide (DR) in Participants with Transplant-Ineligible Newly Diagnosed Multiple Myeloma (TI NDMM)
Time frame: Up to Approximately 8 weeks
DLT events are defined as clinically significant adverse events or abnormal laboratory values assessed as unrelated to disease progression, underlying disease, intercurrent illness, or concomitant medications.
Substudy 2: DLT of Etentamig Monotherapy as Maintenance in Participants with Transplant-Eligible Newly Diagnosed Multiple Myeloma (TE NDMM)
Time frame: Up to Approximately 8 Weeks
DLT events are defined as clinically significant adverse events or abnormal laboratory values assessed as unrelated to disease progression, underlying disease, intercurrent illness, or concomitant medications.
Substudy 3: DLT of Etentamig +Carfilzomib and Dexamethasone (Kd) Combination in Participants with Relapsed or Refractory Multiple Myeloma (RR MM)
Time frame: Up to Approximately 8 Weeks
DLT events are defined as clinically significant adverse events or abnormal laboratory values assessed as unrelated to disease progression, underlying disease, intercurrent illness, or concomitant medications.
Substudy 4: DLT of Etentamig plus Lenalidomide when Given as Maintenance in Participants with TE NDMM
Time frame: Up to Approximately 8 Weeks
DLT events are defined as clinically significant adverse events or abnormal laboratory values assessed as unrelated to disease progression, underlying disease, intercurrent illness, or concomitant medications.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
