New hope for myeloma patients: drug combo trial launches
NCT ID NCT06679101
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 3 trial tests whether a new combination of drugs—belantamab mafodotin, lenalidomide, and dexamethasone—can help people with newly diagnosed multiple myeloma who cannot have a stem cell transplant. The study will compare this new combo to the current standard treatment (daratumumab, lenalidomide, and dexamethasone) in 520 participants. The goal is to see if the new combo delays cancer progression or leads to deeper remission.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- belantamab mafodotin, lenalidomide, and dexamethasone
- What this could lead to
- If successful, this combination could offer a new, more effective first-line treatment option for people with newly diagnosed multiple myeloma who cannot have a stem cell transplant.
- What could go wrong
- This is an early-stage Phase 3 trial, so results are not guaranteed. The new combination may not be better than the current standard, and side effects like eye problems or low blood counts are possible.

Inclusion Criteria: 1. Is at least 18 or the legal age of consent in the jurisdiction in which the study is taking place, at the time of signing the informed consent. 2. Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form and in the protocol. 3. NDMM with a requirement for treatment as documented per IMWG criteria. 4. Must have at least 1 aspect of measurable disease, as assessed by the central laboratory, defined as 1 of the following: 1. Urine M-protein excretion ≥200 mg/24 hours (≥0.2 g/24 hours) And/or 2. Serum M-protein concentration ≥0.5 g/dL (≥5.0 g/L) And/or 3. Serum free light-chain (FLC) assay: involved FLC level ≥10 mg/dL (≥100 mg/L) and an abnormal serum FLC ratio (\<0.26 or \>1.65). 5. Newly diagnosed and not considered candidate for high-dose chemotherapy with autologous stem cell transplant (ASCT) due to any of the following: 1. Exclusion from treatment with ASCT due to country- or site-specific age restriction. 2. Presence of comorbid condition(s) likely to have a negative impact on tolerability of high-dose chemotherapy with ASCT. 6. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2. 7. Adequate organ system function as defined by the laboratory assessments. 8. Male participants: * Contraceptive use by men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. * Male participants are eligible to participate if they agree to the following during the Treatment Period and for at least 6 months after the last dose of study intervention to allow for clearance of any altered sperm: * Refrain from donating fresh unwashed semen PLUS either: * Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent. OR * Must agree to use contraception/barrier as detailed below * Agree to use a male condom, even if they have undergone a successful vasectomy, and female partner to use an additional highly effective contraceptive method with a failure rate of \<1% per year when having sexual intercourse with a woman of childbearing potential (WOCBP) who is not currently pregnant. Male participants should also use a condom when having sexual intercourse with pregnant females. 9. Female participants * Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. * A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least 1 of the following conditions applies: * Is not a WOCBP OR * Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of \<1% per year), preferably with low user dependency during the Treatment Period and for 4 months after the last dose of study intervention and agrees not to donate eggs (ova, oocytes) for the purpose of reproduction during this period. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study intervention. * A WOCBP must have 2 negative highly sensitive serum pregnancy tests before starting treatment, the first may be performed within 14 days from C1D1, the second within 24 hours before the first dose of study intervention. * Should pregnancy occur in a female on treatment or the female partner of a male on treatment, treatment must be stopped, and it is advised to seek advice from a physician specialized or experienced in teratology. Exclusion Criteria: 1. Diagnosis of systemic amyloid light chain amyloidosis, Waldenstrom's disease, POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma proliferative disorder, skin changes) or Primary Plasma Cell Leukemia (defined as circulating plasma cells \>5%). 2. Prior systemic therapy for multiple myeloma, or smoldering multiple myeloma. 3. Signs of meningeal or central nervous system involvement with multiple myeloma. 4.

Participants with hepatitis B will be excluded unless the defined criteria can be met. 12. Current corneal epithelial disease except for mild punctate keratopathy. 13. Intolerance or contraindications to antiviral prophylaxis. 14. Unable to tolerate antithrombotic prophylaxis. 15. Known immediate or delayed hypersensitivity reaction or idiosyncratic reaction to drugs chemically related to belantamab mafodotin, or any of the components of the study intervention. 16.
