- Sex and Contraception/Barrier Requirements (Female):
- 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 woman of childbearing potential (WOCBP) or Due to lenalidomide being a thalidomide analogue with risk for embryofetal toxicity and prescribed under a pregnancy prevention/controlled distribution program, and bortezomib having the potential to cause fetal harm, WOCBP participants will be eligible if they commit to either: abstain continuously from heterosexual sexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent OR to use birth control as follows: Two methods of reliable birth control (one method that is highly effective and one additional effective (barrier) method), beginning 4 weeks prior to initiating treatment with lenalidomide, during therapy, during dose interruptions and continuing for 4 weeks following discontinuation of lenalidomide treatment. Thereafter, WOCBP participants must use one method of reliable birth control that is highly effective for a further 3 months following discontinuation of belantamab mafodotin, or a further 6 months following discontinuation of bortezomib, whichever is longer. WOCBP must also agree not to donate eggs (ova, oocytes) for the purpose of reproduction during treatment, during dose interruptions and for 28-days following the last dose of lenalidomide, 4 months following discontinuation of belantamab mafodotin treatment or 7-months following the last dose of bortezomib, whichever is longer. Two negative pregnancy tests must be obtained prior to initiating therapy. The first test should be performed within 10-14 days and the second test within 24 hours prior to prescribing the start of lenalidomide therapy.
- The participant should not receive lenalidomide until the investigator has verified that the results of these pregnancy tests are negative. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study intervention. The Investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.
- Sex and Contraception/Barrier Requirements (Male):
- 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 from the time of first dose of study treatment until 28-days after the last dose of lenalidomide, 4-months after the last dose of bortezomib, or 6 months after the last dose of belantamab mafodotin, whichever is longer, to allow for clearance of any altered sperm: Refrain from donating sperm - 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 WOCBP. Male participants should also use a condom when having sexual intercourse with pregnant females.

About this study
Official title: A Phase 1, Randomized, Dose and Schedule Evaluation Study to Investigate the Safety, Pharmacokinetics, Pharmacodynamics and Clinical Activity of Belantamab Mafodotin Administered in Combination With Standard of Care in Participants With Newly Diagnosed Multiple Myeloma
This study will evaluate the safety, pharmacokinetics, pharmacodynamics and clinical activity of belantamab mafodotin in combination with Velcade (bortezomib), Revlimid (lenalidomide), dexamethasone (VRd) and will determine recommended phase 3 dose (RP3D) in adult participants with newly diagnosed multiple myeloma (NDMM). Participants will receive the combination of bortezomib, lenalidomide and dexamethasone (VRd) on a 3-week cycle until cycle 8, followed by the combination of lenalidomide and dexamethasone (Rd) on a 4-week cycle thereafter as per dosing schedule. Participants will receive belantamab mafodotin on a schedule that is dependent on the cohort to which they are assigned. Belantamab mafodotin will be administered in combination with VRd every 3 weeks (Q3W), every 6 weeks (Q6W), or every 9 weeks (Q9W) to Cycle 8, and then in combination with Rd every 4 weeks (Q4W), every 8 weeks (Q8W), or every 12 weeks (Q12W) thereafter. Participants will complete an End of Treatment (EOT) visit at the point of study treatment discontinuation, followed by a Safety Follow-up visit 70 days after EOT.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Belantamab mafodotin, Bortezomib and Lenalidomide in people with Multiple Myeloma, run by GlaxoSmithKline at 30 sites in 10 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 17 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 28 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 30 sites in Spain, Germany, United States, Australia, South Korea and 5 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of participants with dose-limiting toxicities (DLTs) (time frame: Treatment cycle 1 to 3 (each cycle of 21 days)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Nov 2025.
