About this study
Official title: A Phase 1/2, Dose and Schedule Evaluation Study to Investigate the Safety and Clinical Activity of Belantamab Mafodotin Administered in Combination With Daratumumab, Pomalidomide and Dexamethasone in Patients With Relapsed/ Refractory Multiple Myeloma Previously Treated With One Line of Therapy Who Are Lenalidomide Refractory.
This is a phase 1/2, open label, single-center study designed to assess the safety and preliminary clinical activity of different belantamab mafodotin doses in combination with daratumumab, pomalidomide, and dexamethasone (DPd) in patients with Relapsed/ Refractory Multiple Myeloma (RRMM) previously treated with one line of therapy who are lenalidomide refractory.
This will be a 2-Part study. Part 1 will evaluate the safety of belantamab mafodotin in combination with DPd in 2 cohorts and determine the Recommended Phase 2 Dose (RP2D). In the dose expansion phase (Part 2) an expansion cohort will be treated with the RP2D. The expansion cohort will randomize participants (1:1) in two groups to evaluate two alternate dose modification guidelines for corneal AEs. Part 2 will further evaluate the safety and assess the preliminary clinical activity of the belantamab mafodotin RP2D in combination with DPd.
Overall, approximately 48 participants will be enrolled in the study. Participant follow-up will continue up to 3 years after the last participant is randomized. The estimated accrual period will be 12 months corresponding to an approximate total study duration of 4 years.

This will be a 2-Part study. Part 1 will evaluate the safety of belantamab mafodotin in combination with DPd in 2 cohorts and determine the Recommended Phase 2 Dose (RP2D). In the dose expansion phase (Part 2) an expansion cohort will be treated with the RP2D. The expansion cohort will randomize participants (1:1) in two groups to evaluate two alternate dose modification guidelines for corneal AEs. Part 2 will further evaluate the safety and assess the preliminary clinical activity of the belantamab mafodotin RP2D in combination with DPd.
Overall, approximately 48 participants will be enrolled in the study. Participant follow-up will continue up to 3 years after the last participant is randomized. The estimated accrual period will be 12 months corresponding to an approximate total study duration of 4 years.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Belantamab Mafodotin-Blmf, Daratumumab and Pomalidomide in people with Multiple Myeloma and Multiple Myeloma in Relapse, run by Hellenic Society of Hematology.
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 37 inclusion and 45 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: status not confirmed, as of the sponsor's last update on 17 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.
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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Maria Pagoni, Dr (+302107211806, info@eae.gr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Part 1: Dose-Limiting Toxicity (DLT) (time frame: Up to 28 days). 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?
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 17 Oct 2022.
