Clinical Trial Summary

The proposal of this study is to retrospectively analyze the experience with belantamab mafodotin monotherapy in patients with RRMM included in the compassionate use or in the expanded access program in Spain between November 2019 and June 2021. The focus of the study will be on the estimation of the magnitude of the treatment effect as assessed by the overall response rate (ORR), duration of response (DOR), progression free survival (PFS), overall survival (OS), and the safety of single agent belantamab mafodotin in patients with RRMM. Subjects may receive treatment until progression. Myeloma disease status will be evaluated locally for response and progression per International Myeloma Working Group (IMWG) criteria from cycle 1 day 1 until confirmed progressive disease, death, unacceptable toxicity, or lost to follow-up (whichever occurs first).

Description:

The proposal of this study is to retrospectively analyze the experience with belantamab mafodotin monotherapy in patients with RRMM included in the compassionate use or in the expanded access program in Spain between November 2019 and June 2021. Subjects may receive treatment until progression. Myeloma disease status will be evaluated locally for response and progression per International Myeloma Working Group (IMWG) criteria from cycle 1 day 1 until confirmed progressive disease, death, unacceptable toxicity, or lost to follow-up (whichever occurs first). The study has the following objectives: Primary objective - The primary objective of this study is to evaluate the efficacy of belantamab mafodotin in terms of overall response, and the different response categories when administered as a single agent in patients with RRMM. Secondary objectives: - Describe the safety and tolerability of single-agent belantamab mafodotin. - The overall incidence of ophthalmologic complications. - Estimate duration of response (DOR). - Estimate time to response (TTR). - Estimate time to next treatment (TTNT). - Estimate progression-free survival (PFS) and overall survival (OS). - Type of treatment administered after single-agent belantamab mafodotin and estimate PFS2.
