What Blue Cross Blue Shield of Michigan's policy requires for amyloidosis (cardiac attr + al)

Cited policy: BCBS Darzalex Faspro + VCd (D-VCd) for Newly-Diagnosed AL Amyloidosis

Adult with newly-diagnosed systemic AL amyloidosis confirmed by tissue biopsy + mass-spec typing OR immunoelectron microscopy identifying kappa or lambda light chains. Mayo 2012/2014 stage I-IIIa (not IIIb in many policies). Measurable hematologic disease (dFLC >=50 mg/L OR involved/uninvolved sFLC ratio abnormal OR M-protein quantifiable).

How Blue Cross Blue Shield of Michigan denies amyloidosis (cardiac attr + al) — and how to counter it

Where Blue Cross Blue Shield of Michigan pushes back: 1) Bortezomib-based induction (CyBorD) without daratumumab is sufficient first-line; 2) Reserve daratumumab for relapsed/refractory; 3) Mayo stage IIIb excluded.

Counter-arguments that hold up: ANDROMEDA (Kastritis NEJM 2021) — D-VCd vs VCd in newly-dx AL (n=388): hematologic CR 53% vs 18%, cardiac response 42% vs 22%, MRD-negativity higher with D-VCd. FDA approved Darzalex Faspro D-VCd combination on January 15, 2021 — the ONLY FDA-approved regimen specifically for AL amyloidosis. NCCN Category 1 first-line. CyBorD-without-daratumumab is now considered inferior to D-VCd for daratumumab-eligible patients. Mayo stage IIIb requires individualized review with attention to cardiac safety (slow-titration bortezomib + reduced-dose dexamethasone).
