A new treatment approach for relapsed or refractory multiple myeloma in adults

Official title: A Phase 3 Randomized Study Comparing IBI3003 Versus Treatment Per Investigator's Choice in Participants With Relapsed or Refractory Multiple Myeloma

Run by Innovent Biologics (Suzhou) Co. Ltd. · NCT07623798 · Data updated 2026-11-12

This study tests if IBI3003 works better than the investigator's choice treatment for adults whose multiple myeloma has returned or persisted after prior therapy.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with relapsed or refractory multiple myeloma who have had 1–4 prior therapies and prior exposure to proteasome inhibitors, immunomodulators, and anti-CD38 antibodies.

Probably not a fit

Patients whose disease does not respond to IBI3003 or who experience intolerable side effects may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a multicenter, open-label Phase 3 trial comparing IBI3003 to the investigator's choice regimen (DPd, PVd, or SVd) in adults with relapsed or refractory multiple myeloma who have had 1–4 prior therapies and exposure to three drug classes. Approximately 255 participants will be randomized in a 2:1 ratio, with the experimental group receiving IBI3003 and re-treatment considered after stopping criteria are met. The study includes standard myeloma-directed agents (pomalidomide, bortezomib, daratumumab) in the regimens and allows for re-treatment with IBI3003 upon re-treatment criteria in discussion with investigators and sponsor. Safety and efficacy outcomes will guide comparisons between the experimental and control arms.

Why it matters

Potential benefit: If successful, participants may experience improved disease control and longer responses with IBI3003 compared with standard regimens.

How similar studies have gone: Previous trials in similar relapsed/refractory myeloma settings have shown potential benefits with novel agents in comparable populations, but this exact approach is specific to IBI3003.

Inclusion Criteria:

1. Age ≥18 years.
2. Documented initial diagnosis of multiple myeloma according to IMWG diagnostic criteria.

   * Serum M-protein ≥ 5 g/L(For IgA and IgD subtypes, it is recommended to use quantitative immunoglobulin measurements instead of M protein)
   * Urine M-protein ≥200 mg/24h
   * Serum free light chain (FLC) test: affected FLC level ≥100 mg/L and abnormal serum FLC ratio (\<0.26 or \>1.65)
4. Life expectancy ≥3 months.

For participants in the clinical trial, contraceptive measures must comply with local regulations regarding the use of contraceptive methods. Females and males must agree not to donate eggs (ova, oocytes) or sperm during the study and for 90 days after the last dose of the investigational drug.
6. Willing and able to comply with the prohibitions and restrictions specified in this protocol.

2. Known active CNS involvement or exhibits clinical signs of meningeal involvement of multiple myeloma.
3. Spinal cord compression that leads to limited self-care ability occurs within six months prior to informed consent or is expected to occur in the near future.
