An off-label primary therapy combination with carfilzomib, lenalidomide, and dexamethasone is listed but requires the prescriber to submit supporting evidence. Coverage is subject to the policy's specified dosing, prior therapy, prescriber, and documentation requirements.

Prior Authorization

Prior authorization required

Prior authorization may be required for Sarclisa and for listed prior therapies per plan processes. Providers should anticipate PA requirements for lenalidomide, bortezomib, carfilzomib (Kyprolis), and ixazomib (Ninlaro) when requesting coverage for isatuximab-containing regimens or when documenting prior lines of therapy.

Documentation Required

Submit supporting documentation

Submit supporting documentation such as office chart notes, laboratory results, and other clinical information that demonstrate the member meets all approval criteria for Sarclisa (diagnosis, prior therapies, prescriber specialty, age, dosing, and regimen requirements).

Clinical Evidence & References

Primary evidence sources used to align coverage: Sanofi Sarclisa Prescribing Information (October 2024); key clinical trial ICARIA-MM (Lancet 2019) evaluating isatuximab + pomalidomide + dexamethasone; and the NCCN Multiple Myeloma Version 1.2025 guideline/compendium.

Background

Isatuximab-irfc (Sarclisa) is a CD38-directed cytolytic antibody indicated in combination regimens for adult patients with multiple myeloma. This policy aligns coverage to FDA-approved indications and NCCN recommendations, and specifies dosing schedules, duration (treat until disease progression or unacceptable toxicity), and prior therapy requirements. Definitions: MM = multiple myeloma; PI = proteasome inhibitor (e.g., bortezomib, carfilzomib, ixazomib); ASCT = autologous stem cell transplant.
