Mogamulizumab

Mogamulizumab is an antibody that clears cancerous T cells from the blood in mycosis fungoides and Sézary syndrome, the leukaemic form of skin lymphoma.

MAVORIC (2018): PFS 7.7 vs 3.1 months versus vorinostat, with the best responses in blood compartment and Sézary syndrome. Approved in Japan (2012) for ATLL and CCR4+ PTCL/CTCL; US/EU 2018 for MF/SS after one systemic therapy. Rash (mogamulizumab-associated rash) and increased GVHD risk after subsequent allogeneic transplant.

Medicare
Part B (clinician-administered)

Given by infusion or injection in a clinic or hospital outpatient department, so it is a Part B drug: Medicare pays 80% after the Part B deductible and the patient owes 20% coinsurance, uncapped in Original Medicare unless a Medigap policy applies.

Commercial insurance
covered with prior authorisation

Covered under the medical benefit with prior authorisation confirming diagnosis, biomarker status and line of therapy; site-of-care policies may steer infusions away from hospital outpatient departments.

20% Part B coinsurance on a high-cost infusion adds up quickly: Medigap Plan G or N, Medicare Advantage maximum out-of-pocket, Medicaid dual eligibility, or a charity fund are the usual buffers.
