Summary

This study offers continued treatment with isatuximab (a targeted antibody) to adults with multiple myeloma who were already benefiting from it in earlier trials. About 70 participants will receive the drug, possibly combined with other medications, to monitor long-term safety. The goal is to ensure patients can keep accessing a therapy that works for them.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Isatuximab (with possible cemiplimab, dexamethasone, lenalidomide, or pomalidomide)
What this could lead to
If successful, this study could show that long-term isatuximab treatment is safe and continues to control multiple myeloma, offering ongoing benefit to patients.
What could go wrong
This is a small, open-label extension study (70 participants) focused on safety, not on proving new effectiveness. It may not show clear long-term benefits or apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Participant must be ≥18 years of age (or the legal age of consent in the jurisdiction in which the study is taking place), at the time of signing the informed consent. * Participants of a parental Phase 1, 2, or 3 clinical study assessing isatuximab monotherapy or in a combination regimen with all the study objectives completed. * Participants still receiving isatuximab at the time of the parental study closure, who are continuing to benefit from isatuximab as monotherapy or in combination, as determined by the treating physician, and who meet the criteria to initiate a subsequent cycle of therapy as described in the parental study protocol. A participant not receiving isatuximab at the end of the parental study who does not have access locally to the ongoing treatment may also be included. * Contraception (with double contraception methods) for male and female participants; not pregnant or breastfeeding for female participants; no sperm donation for male participants. * Capable of giving signed informed consent. Exclusion Criteria: * Participant has evidence of progressive disease during or at the time of the parental study closure. * Participant has not recovered to ≤Grade 2 from nonhematologic AEs (as per NCI CTCAE v5.0) related to any anticancer therapy received prior to signing informed consent on the extension study. * As the latest line of treatment participant received an antimyeloma therapy other than the isatuximab-based therapy in the parental study before the first IMP in this study. * Individuals accommodated in an institution because of regulatory or legal order; prisoners or participants who are legally institutionalized. * Participant not suitable for participation, whatever the reason, as judged by the Investigator, including medical or clinical conditions, or participants potentially at risk of noncompliance to study procedures. * Participants are employees of the clinical study site or other individuals directly involved in the conduct of the study, or immediate family members of such individuals. * Any country-related specific regulation that would prevent the participant from entering the study. The above information is not intended to contain all considerations relevant to a potential participation in a clinical trial.
