ENDEAVOR: Kd beat Vd (PFS 18.7 vs 9.4 months, OS benefit). Used in KRd and Isa-Kd/Dara-Kd; ENDURANCE showed no frontline advantage of KRd over VRd in standard-risk disease. Amgen.

- 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. HCPCS J9047.
- 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.
- Assistance programmes
- Amgen SupportPlus
- Amgen Safety Net Foundation
- PAN Foundation — Disease-specific co-pay and premium funds; open and closed funds change monthly.
- HealthWell Foundation
- CancerCare Co-Payment Assistance Foundation
- Patient Advocate Foundation Co-Pay Relief
- Leukemia & Lymphoma Society financial support
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.
