Study Details

Study Description

Brief Summary

Multiple myeloma (MM) is a rare cancer caused by abnormal survival of plasma cells (blood cells). Most trial participants with MM relapse (cancer has come back) or become non- responsive to treatment and remission gets shorter after each line of treatment. This is a study to determine recommended Phase 2 dose and change in disease symptoms of eftozanermin alfa in combination with bortezomib and dexamethasone to assess how efficient the treatment is in adult participants with relapsed/refractory (R/R) MM.

Eftozanermin alfa (ABBV-621) is an investigational drug being developed for the treatment of R/R Multiple Myeloma (MM). Study doctors put the participants in 1 of the 2 groups, called treatment arms. Each group receives a different treatment. Participants in one arm will receive different doses of eftozanermin alfa in combination with bortezomib and dexamethasone to determine phase 2 dose (RP2D). Participants in the other arm will receive eftozanermin alfa at RP2D in combination with bortezomib and dexamethasone. Around 40 adult participants with relapsed/refractory multiple myeloma will be enrolled at approximately 20 sites across the world.

Participants will receive eftozanermin alfa as an infusion into the vein in combination with bortezomib as an infusion into the vein or an injection under the skin and oral dexamethasone tablets for 12 cycles. Each cycle is 21 days for cycles 1-8 and 35 days for cycles 9-12.

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 a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects.

    Outcome Measures

    Primary Outcome Measures

    1. Recommended Phase 2 Dose (RP2D) of Eftozanermin Alfa in Combination With Bortezomib and Dexamethasone (Safety Lead-In Arm) [Up to approximately 3 weeks after the first dose of study drug]

      RP2D of eftozanermin alfa in combination with bortezomib and dexamethasone will be determined.

    2. Objective Response Rate (ORR) (Dose Expansion Arm) [Up to approximately 44 weeks after the first dose of study drug]

      ORR is defined as percentage of participants with a response of partial response (PR) or better per IMWG criteria.

    Secondary Outcome Measures

    1. Rate of VGPR or Better per IMWG Criteria [Up to approximately 44 weeks after the first dose of study drug]

      Percentage of participants with a response of VGPR or better per IMWG criteria will be assessed.

    2. Duration of Response (DOR) for ORR [Up to approximately 44 weeks after the first dose of study drug]

      DOR for ORR is defined as the number of days from the date of first response (PR or better) to the date of first occurrence of progressive disease (PD) or death from any cause, whichever occurs first.

    3. Duration of Response (DOR) for VGPR or Better [Up to approximately 44 weeks after the first dose of study drug]

      DOR for VGPR or better rate is defined as the number of days from the date of first response (VGPR or better) to the date of first occurrence of PD or death from any cause, whichever occurs first.

    4. Number of Participants With Dose-Limiting Toxicities (DLTs) [Up to approximately 3 weeks after the first dose of study drug]

      DLTs are any of the hematologic, nonhematologic toxicities, adverse events (AEs) occurring following administration of study drug as described in the protocol and evaluated by the Investigator and the sponsor.

    5. Number of Participants With Adverse Events (AEs) [Up to approximately 44 weeks after the first dose of study drug]

      An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. The investigator will assess the relationship of each event to the use of study drug as being of reasonable possibility or no reasonable possibility. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the subject and may require medical or surgical intervention to prevent any of the outcomes listed above.

    6. Change in Vital Sign Measurements [Up to approximately 44 weeks after the first dose of study drug]

      Change from baseline in vital sign measurements such as systolic and diastolic blood pressure will be assessed.

    7. Electrocardiogram (ECG) [Up to approximately 44 weeks after the first dose of study drug]

      Participants with change from baseline in ECG variables will be assessed.

    8. Number of Participants With Abnormal Clinical Laboratory Test Results [Up to approximately 44 weeks after the first dose of study drug]

      Number of participants with abnormal clinical laboratory test results like hematology will be assessed.

    9. Trough Concentration (Ctrough) of Eftozanermin Alfa [Up to Day 106]

      Serum concentration prior to administration of study drug.

    10. Maximum Serum Concentration (Cmax) of Eftozanermin Alfa [Up to Day 8]

      Serum concentration at 15 min after end of infusion.
