Introduction:
Although new drug classes have significantly extended survival of patients with multiple myeloma, they continue to experience multiple relapses and/or become refractory to treatment. Therefore, novel therapies and treatment combinations with different mechanisms of action are needed to improve the outcomes of patients with relapsed/refractory multiple myeloma.
Areas Covered:
Here, the authors review the published data regarding the development and clinical investigation of isatuximab, a CD38 monoclonal antibody, for treatment of patients with relapsed/refractory multiple myeloma. The mechanisms of action, clinical efficacy, and safety of isatuximab treatment are summarized.
Expert Opinion:
Isatuximab is approved in combination with pomalidomide/dexamethasone for the treatment of adults with relapsed/refractory multiple myeloma who have received at least two prior therapies, including lenalidomide and a proteasome inhibitor. Isatuximab displays a manageable safety profile, with infusion reactions being the most common adverse events. Isatuximab is currently being further evaluated in combination with other backbone regimens in relapsed/refractory and newly diagnosed multiple myeloma.
Insights
Isatuximab, a CD38 monoclonal antibody, offers a new treatment option for relapsed/refractory multiple myeloma. It shows a manageable safety profile and is being evaluated in further combinations for improved patient outcomes.
Area of Science:
- Oncology
- Immunotherapy
- Hematology
Background:
- Multiple myeloma patients often face relapses and treatment resistance despite new therapies.
- Novel treatment strategies are crucial for improving outcomes in relapsed/refractory multiple myeloma.
Purpose of the Study:
- To review the development and clinical investigation of isatuximab for relapsed/refractory multiple myeloma.
- To summarize the mechanism of action, efficacy, and safety of isatuximab.
Main Methods:
- Review of published data on isatuximab's development and clinical trials.
- Summary of isatuximab's mechanism of action, efficacy, and safety profile.
Main Results:
- Isatuximab is approved in combination with pomalidomide/dexamethasone for specific relapsed/refractory multiple myeloma patients.
- Isatuximab has a manageable safety profile, with infusion reactions as the most common adverse events.
Conclusions:
- Isatuximab represents a valuable therapeutic option for relapsed/refractory multiple myeloma.
- Ongoing evaluations of isatuximab in combination regimens aim to further enhance treatment efficacy.
