Background, Evidence & Definitions

Background: The guideline bases coverage decisions on the FDA labeling and recognized compendia/guidelines (CMS‑approved compendia, NCCN, ASCO, or peer‑reviewed literature meeting CMS Chapter 15). There is a US boxed warning for cytokine release syndrome (CRS); patients should be monitored for at least 16 hours after each of the first three infusions and then as clinically indicated. Exclusion criteria include disease progression on Kimmtrak, single-dose dosing that exceeds 68 mcg, and concurrent use with other anti-cancer therapies. The policy also excludes investigational or off-label uses that lack sufficient evidence as defined by the guideline. Coding information includes HCPCS code J9274 (injection, tebentafusp-tebn, 1 microgram).

Evidence	Reference
Key trial	IMCgp100-202 (Nathan P et al.), NEJM 2021 showing overall survival benefit in metastatic uveal melanoma
Prescribing information	Kimmtrak prescribing information, Immunocore Commercial LLC, 2024

Definitions: "Sufficient evidence" follows CMS compendia and Medicare Benefit Policy Manual Chapter 15 standards — evidence must be supported by CMS‑recognized compendia or acceptable peer‑reviewed literature, consider whether patient and regimen characteristics are represented, ensure regimen fidelity and appropriate study design, and demonstrate clinically meaningful outcomes (ASCO examples such as hazard ratio < 0.80 and at least a 3‑month OS/PFS benefit); case reports and meeting abstracts without full peer‑reviewed articles are generally insufficient.
