Current Status: Why Blenrep Coverage is Denied

Blenrep (belantamab mafodotin) was voluntarily withdrawn from the U.S. market by GSK in November 2022 after the DREAMM-3 confirmatory trial didn't meet its primary endpoint. This means Aetna CVS Health cannot provide standard commercial coverage because the drug lacks FDA marketing approval.

However, there's hope on the horizon. GSK has resubmitted Blenrep to the FDA based on positive results from the DREAMM-7 trial, which showed the combination of Blenrep plus bortezomib and dexamethasone reduced the risk of disease progression or death by 59% compared to a Darzalex-based combination. The FDA's target decision date is October 23, 2025.

Eligibility Triage: Do You Qualify for Access?

Since standard coverage isn't available, let's determine your best path to access:

Likely Eligible for Clinical Trial or Compassionate Use

You likely qualify if you have:

  • Confirmed relapsed/refractory multiple myeloma
  • Failed 4 or more prior therapies
  • No suitable treatment alternatives available
  • ECOG performance status 0-2
  • Adequate organ function
  • Oncologist willing to enroll you in REMS program

Possibly Eligible

⚠️ You might qualify if you have:

  • Relapsed/refractory multiple myeloma with 2-3 prior therapies
  • Contraindications to other available treatments
  • Rapidly progressive disease
  • Previous response to anti-BCMA therapy

Not Yet Eligible

Consider alternatives first if you have:

  • Newly diagnosed multiple myeloma
  • Haven't tried standard therapies (lenalidomide, bortezomib, dexamethasone combinations)
  • Suitable clinical trial options for other investigational agents
  • Good response to current therapy

If You're Likely Eligible: Clinical Trial and Compassionate Use Paths

Document Checklist

Before contacting GSK or clinical trial sites, gather:

  • Medical records showing multiple myeloma diagnosis with ICD-10 codes
  • Prior therapy documentation including dates, doses, and reason for discontinuation
  • Recent lab results (CBC, comprehensive metabolic panel, LDH, beta-2 microglobulin)
  • Imaging studies showing current disease status
  • Ophthalmologic evaluation (required due to Blenrep's ocular toxicity)

Submission Path: Compassionate Use

Step 1: Your oncologist must initiate the request

Step 2: Complete regulatory requirements

  • IRB approval (if required by institution)
  • Informed consent process
  • REMS training completion
From Our Advocates: We've seen patients successfully access Blenrep through compassionate use when their oncologist documented exhaustion of all other BCMA-targeted options and provided clear evidence of progressive disease. The key is having a specialist familiar with the REMS requirements who can articulate why this specific therapy is medically necessary.

If You're Possibly Eligible: Building Your Case

Tests to Request

Ask your oncologist about:

  • Flow cytometry to confirm BCMA expression on plasma cells
  • Cytogenetics/FISH to identify high-risk features
  • PET/CT scan to document extent of disease
  • Comprehensive ophthalmologic exam with optical coherence tomography

What to Track

Document everything that could strengthen your case:

  • Response duration to prior therapies
  • Adverse events that limited other treatments
  • Quality of life impacts from current disease burden
  • Rate of progression between treatments

Timeline to Re-apply

  • Clinical trials: New studies open regularly; check monthly
  • Compassionate use: Can reapply if disease progresses or other options fail
  • Commercial coverage: Monitor FDA decision expected October 23, 2025

If Not Yet Eligible: Alternative Treatments

Q: Can I get Blenrep through my Aetna plan right now? A: No, because GSK withdrew it from the U.S. market. Access is only through clinical trials or compassionate use programs.

Q: What's the success rate for appeals in California? A: California's Independent Medical Review has a 55-72% success rate for specialty oncology drugs, significantly higher than the national average.

Q: Do I need to try CAR-T therapy before Blenrep? A: When Blenrep returns, step therapy requirements will depend on Aetna's updated policy. Currently, ide-cel and cilta-cel are FDA-approved alternatives.

Q: How long does compassionate use approval take? A: Typically 2-4 weeks once your oncologist submits a complete request through GSK's portal.

Q: What if my oncologist isn't familiar with the REMS program? A: GSK provides training materials and support. The REMS program is mandatory due to Blenrep's potential for serious eye problems.

Q: Can I appeal to California regulators if denied compassionate use? A: Compassionate use decisions are made by GSK, not insurance companies. However, you can file complaints with the FDA if you believe you're inappropriately denied access.
