Getting Blenrep (Belantamab Mafodotin) Covered by Humana in North Carolina: PA Requirements, Appeals, and Alternative Options

Answer Box: Fast Track to Blenrep Coverage

Blenrep (belantamab mafodotin) received FDA approval on October 23, 2025, for relapsed/refractory multiple myeloma after 2+ prior therapies. Humana Medicare typically covers FDA-approved oncology drugs but requires prior authorization. Your fastest path: 1) Have your oncologist submit Humana's "Request for Medicare Prescription Drug Coverage Determination" form with detailed medical necessity documentation, 2) Request expedited review if treatment delay risks harm, 3) If denied, file internal appeal within 65 days. North Carolina residents can escalate to external review through Smart NC within 120 days of final denial.

When Blenrep Alternatives Make Sense

Since Blenrep (belantamab mafodotin) just received FDA approval in October 2025, many Humana formularies may not yet include it or may place it on higher tiers requiring substantial copays. Understanding when formulary alternatives are clinically appropriate—and when they're not—helps you and your oncologist develop the strongest coverage strategy.

Alternatives may be appropriate when:

  • You haven't yet tried standard BCMA-targeted therapies
  • Blenrep faces significant access delays (specialty pharmacy, REMS monitoring setup)
  • Your insurance covers alternatives at lower tiers with faster approval

Alternatives are typically NOT appropriate when:

  • You've failed prior BCMA-targeted treatments
  • You have contraindications to daratumumab, bortezomib, or other standard agents
  • Your disease is rapidly progressing and requires immediate BCMA targeting

The key is documenting why alternatives won't work for your specific situation—this becomes crucial evidence for formulary exception requests.


Typical Formulary Alternatives by Class

BCMA-Targeted Therapies

CAR-T Therapies (Carvykti, Abecma): Require ≥4 prior lines including proteasome inhibitor, immunomodulatory agent, and anti-CD38 antibody. Coverage follows CMS criteria but requires specialized infusion centers and hospitalization.

Bispecific Antibodies (Teclistamab, Elranatamab): Newer BCMA-targeted options with outpatient potential but may face similar formulary placement challenges as Blenrep.

Standard Triplet Regimens

DVd (Daratumumab/Bortezomib/Dexamethasone): Control arm in Blenrep's DREAMM-7 trial. FDA-approved for relapsed/refractory multiple myeloma but showed inferior outcomes compared to Blenrep combinations.

Other Daratumumab Combinations: Various formulations typically covered on Humana formularies with established PA pathways.

When Blenrep Isn't the Right Choice

Sometimes pursuing formulary alternatives makes clinical and practical sense. Consider this approach when:

Access Barriers Are Significant:

  • REMS monitoring requirements create substantial delays
  • Specialty pharmacy coordination is complex
  • Your treatment center lacks ophthalmology support for required eye exams

Alternative Therapies Are Clinically Appropriate:

  • You haven't exhausted standard BCMA-targeted options
  • CAR-T therapy is available and you meet criteria
  • Clinical trial enrollment is possible

Insurance Coverage Is Substantially Better:

  • Formulary alternatives are tier 2-3 vs. tier 5 for Blenrep
  • Step therapy requirements can be met quickly
  • Your plan has established PA pathways for alternatives

The goal is always getting you the most effective treatment with the least delay. Sometimes that means starting with a covered alternative while simultaneously appealing for Blenrep coverage.


Re-trying for Blenrep Later

If you start with an alternative therapy, document everything for a future Blenrep appeal:

Track Treatment Response:

  • Regular lab values and imaging results
  • Side effects and quality of life impacts
  • Time to progression or treatment failure

Maintain Appeal Rights:

  • New PA requests aren't bound by previous denials
  • Changed clinical circumstances support new requests
  • Additional evidence (real-world data, updated guidelines) strengthens cases
