  • Female participants: contraceptive use 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 one of the following conditions applies:
  • Is not a woman of childbearing potential (WOCBP) OR
  • Is a WOCBP and using 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. 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 or 4 months following discontinuation of belantamab mafodotin treatment whichever is longer. For contraception guidance please refer to Appendix 2.
  • A WOCBP must have two negative pregnancy tests prior to initiating therapy. The first test should be performed within 10-14 days and the second test within 24 hours prior to 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 a nearly undetected pregnancy.
  • WOCBP is a female who:
  • has achieved menarche at some time point
  • has not undergone a hysterectomy or bilateral oophorectomy or

  • Male participants: contraceptive use 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 intervention period and until 28 days after the last dose of lenalidomide 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 as when having sexual intercourse with a woman of childbearing potential (including pregnant females).
  • Participants must be able to understand the study procedures and agree to participate in the study by providing written informed consent.

About this study

Official title: A Phase 1/2 Study of Belantamab Mafodotin in Combination With Lenalidomide and Dexamethasone in Transplant-ineligible Patients With Newly Diagnosed Multiple Myeloma

This is a phase 1/2, open label, study designed to assess the safety and clinical activity of different Belantamab Mafodotin doses in combination with lenalidomide and dexamethasone.

Read the detailed description

This is a phase 1/2, open label, study designed to assess the safety and clinical activity of different Belantamab Mafodotin doses in combination with lenalidomide and dexamethasone.

The study is comprised of two distinct parts: Part 1 will evaluate different doses of belantamab mafodotin in combination with lenalidomide and dexamethasone in up to 3 cohorts and will determine the recommended Phase 2 dose (RP2D) to be further evaluated for safety and clinical activity in the dose expansion cohort (Part 2). The RP2D dose will be used for future studies in the transplant-ineligible newly diagnosed MM setting. Part 2 of the study will also evaluate an alternative dose modification guideline for corneal adverse events.

Participants will undergo visits and assessments in accordance with the Schedule of Assessments (SoA).

Overall, approximately 66 participants will be enrolled in the study. Participant follow up will continue until 5 years after the last participant is randomized. The estimated accrual period will be 12 months corresponding to an approximate total study duration of 6 years.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Belantamab mafodotin in people with Multiple Myeloma, run by Hellenic Society of Hematology at 1 site in Greece.

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 45 inclusion and 39 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 24 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Greece. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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) in each of the cohorts 1-3 (time frame: Five (5) years after last participant randomization). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04808037, which also lists 2 linked publications.

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 24 Oct 2023.
