Trial Summary

What is the purpose of this trial?

The purpose of this study is to assess the pharmacokinetics (PK), safety, and tolerability of belantamab mafodotin monotherapy in Relapsed/Refractory Multiple Myeloma (RRMM) participants with impaired hepatic function and in matched RRMM participants with normal hepatic function.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug Belantamab Mafodotin for treating multiple myeloma?

Research shows that Belantamab Mafodotin has been effective in treating patients with multiple myeloma who have tried several other treatments. In one study, about 32% of patients had a positive response, and in another, 41.8% showed improvement, indicating its potential as a treatment option for this condition. ^{1 2 3 4 5}

Is Belantamab Mafodotin safe for humans?

Belantamab Mafodotin has been studied for safety in patients with multiple myeloma, showing common side effects like eye problems (keratopathy, blurred vision) and low blood platelet counts (thrombocytopenia). It is available only through a special program due to these risks, indicating that while it can be effective, it requires careful monitoring for safety. ^{2 3 6 7 8}

What makes the drug Belantamab Mafodotin unique for treating multiple myeloma?

Belantamab Mafodotin is unique because it is a first-in-class antibody-drug conjugate that targets BCMA (B-cell maturation antigen) on myeloma cells, delivering a powerful cancer-killing agent directly to the cells. This drug is specifically used for patients with multiple myeloma who have already tried several other treatments, making it a novel option for those with relapsed or refractory disease. ^{3 4 5 9 10}

Findings from Research

The budget impact analysis of belantamab mafodotin (belamaf) for patients with relapsed/refractory multiple myeloma indicates that its introduction would be budget neutral for a US health plan, with minimal cost changes over 3 years.

In a hypothetical health plan with 1 million members, only 33 patients were identified as eligible for treatment, and the analysis showed that the budget impact was most sensitive to treatment duration and drug acquisition costs.

Budget Impact of Belantamab Mafodotin (Belamaf) Adoption in the Treatment of Patients with Relapsed or Refractory Multiple Myeloma in the United States. Shah, A., Tosh, JC., Ambavane, A., et al.[2022]

In a study of 156 patients with relapsed and refractory multiple myeloma, belantamab-mafodotin (belamaf) demonstrated an overall response rate of 41.8%, with significant improvements in progression-free survival for those achieving at least minimal response (MR).

The safety profile of belamaf was manageable, with corneal events being the most common adverse effects, affecting 87.9% of patients, though only 1.3% discontinued treatment due to ocular toxicity.

Belantamab Mafodotin in Patients with Relapsed/Refractory Multiple Myeloma: Results of the Compassionate Use or the Expanded Access Program in Spain. de la Rubia, J., Alonso, R., Clavero, ME., et al.[2023]

Belantamab mafodotin (belamaf) significantly improves overall survival (OS) and duration of response (DoR) in patients with relapsed/refractory multiple myeloma compared to selinexor plus low-dose dexamethasone, with a hazard ratio of 0.53 for OS and 0.41 for DoR, indicating its efficacy as a treatment option.

Belamaf also shows a favorable safety profile, with fewer severe adverse events compared to selinexor plus dexamethasone, making it a promising single-agent therapy for patients who have already undergone multiple lines of treatment.

Belantamab mafodotin (belamaf) is an effective treatment for relapsed or refractory multiple myeloma, showing a 32% overall response rate in the phase II DREAMM-2 study with 95 patients.

While most patients experienced microcyst-like epithelial changes (MECs) as a side effect, these were generally manageable, with a high resolution rate and no permanent vision loss reported, indicating a need for careful monitoring and collaboration between eye care and oncology professionals.

Belantamab mafodotin is a first-in-class monoclonal antibody-drug conjugate designed to treat relapsed or refractory multiple myeloma by targeting B-cell maturation antigen (BCMA) and delivering a cytotoxic agent directly to cancer cells.

It received regulatory approval in the USA and EU in August 2020 based on promising results from the DREAMM-2 trial, specifically for patients who have undergone at least four prior therapies.

Belantamab Mafodotin: First Approval. Markham, A.[2021]

In a study of 106 heavily pretreated patients with relapsed/refractory multiple myeloma, belantamab mafodotin showed an overall response rate of 45.5% and a median overall survival of 14.5 months, indicating its efficacy in a real-world setting.

The treatment was associated with significant adverse effects, particularly ocular toxicity (68.4% experienced keratopathy), but the overall toxicity profile was considered tolerable, suggesting that the benefits may outweigh the risks for many patients.

Belantamab mafodotin (BLENREP) received accelerated FDA approval for treating relapsed or refractory multiple myeloma in adults who have undergone at least four prior therapies, showing an overall response rate of 31% to 34% in the DREAMM-2 trial with 2.5 or 3.4 mg/kg doses.

The most common side effect was keratopathy, affecting 71% to 77% of patients, leading to a boxed warning for ocular toxicity, indicating the need for careful monitoring and a restricted distribution program.

FDA Approval Summary: Belantamab Mafodotin for Patients with Relapsed or Refractory Multiple Myeloma. Baines, AC., Ershler, R., Kanapuru, B., et al.[2023]

Belantamab mafodotin, an antibody-drug conjugate, has shown significant efficacy and manageable safety in treating heavily pretreated relapsed/refractory multiple myeloma, as demonstrated in the phase I DREAMM-1 and phase II DREAMM-2 studies.

The recommended dose of belantamab mafodotin is 2.5 mg/kg every 3 weeks, with safety outcomes like corneal events and thrombocytopenia being closely linked to drug exposure, highlighting the importance of monitoring patient characteristics and disease burden in treatment planning.

Exposure-Response Analyses for Therapeutic Dose Selection of Belantamab Mafodotin in Patients With Relapsed/Refractory Multiple Myeloma. Ferron-Brady, G., Rathi, C., Collins, J., et al.[2022]

Belantamab mafodotin (belamaf) is an approved treatment for adults with relapsed/refractory multiple myeloma, showing effectiveness by targeting BCMA and eliminating myeloma cells through multiple mechanisms.

The ongoing DREAMM-5 study is exploring the safety and efficacy of belamaf in combination with other novel therapies, which may enhance its anticancer effects compared to belamaf alone.

In the DREAMM-2 study, after 13 months of follow-up, 32% of patients with relapsed or refractory multiple myeloma achieved an overall response to belantamab mafodotin (belamaf) at a dose of 2.5 mg/kg, indicating its efficacy in a heavily pretreated population.

The study found that belamaf maintained clinical activity without new safety concerns, even in patients experiencing prolonged dose delays due to corneal events, suggesting it is a safe treatment option for this patient group.
