When Alternatives Make Sense

Sometimes pursuing Aetna's preferred alternatives first can actually speed your path to Hemlibra approval. Consider alternatives when:

  • Initial PA is denied for step therapy reasons - demonstrating failure of preferred agents strengthens your case
  • You haven't tried factor VIII products recently - current treatment history may be required
  • Urgent bleeding control is needed - some alternatives work faster for acute episodes
  • Cost considerations - while awaiting appeals, alternatives may provide interim coverage

Important: Never switch treatments without your hematologist's guidance. Factor VIII and Hemlibra have different mechanisms and monitoring requirements.

Typical Formulary Alternatives

Factor VIII Concentrates (Preferred for Non-Inhibitor Patients)

  • Kovaltry - Often Aetna's preferred agent
  • Advate, Kogenate, Recombinate - May require step therapy from Kovaltry
  • Coverage: Generally covered with PA for prophylaxis and on-demand treatment
  • Requirements: Hemophilia A diagnosis, weight-based dosing plan

Bypassing Agents (for Inhibitor Patients)

  • Activated Prothrombin Complex Concentrate (aPCC)
  • Recombinant Factor VIIa (rFVIIa)
  • Coverage: Typically for acute bleeding episodes, not routine prophylaxis
  • Limitations: Higher cost, more complex administration

Emerging Non-Factor Options

  • Concizumab, Hympavzi - Newer agents with limited formulary placement
  • Coverage: Varies significantly by plan; often require extensive documentation
From our advocates: We've seen patients successfully transition from factor VIII to Hemlibra by maintaining detailed bleeding logs during the alternative therapy trial. This documentation becomes crucial evidence for medical necessity when resubmitting for Hemlibra approval.

Pros and Cons Overview

Factor VIII Concentrates

Pros:

  • Well-established coverage pathways
  • Multiple dosing options
  • Extensive clinical experience
  • Can be used for both prophylaxis and acute treatment

Cons:

  • Requires more frequent dosing than Hemlibra
  • Risk of inhibitor development
  • IV administration vs. subcutaneous
  • May not be effective for patients with high-titer inhibitors

Hemlibra (emicizumab-kxwh)

Pros:

  • Subcutaneous administration
  • Less frequent dosing (weekly to monthly)
  • Effective regardless of inhibitor status
  • Reduced treatment burden

Cons:

  • Requires specialty pharmacy coordination
  • Cannot be used with routine factor VIII prophylaxis
  • Limited experience with breakthrough bleeding management
  • Higher initial access barriers

Exception Strategy

When to Request a Formulary Exception

Request an exception when:

  • Step therapy is inappropriate due to inhibitors or documented factor VIII failure
  • Medical contraindications exist to preferred alternatives
  • Previous treatment failures are well-documented
  • Urgent clinical need exists (active bleeding, upcoming surgery)

Evidence That Helps

Re-trying for Hemlibra Later

What to Document During Alternative Therapy Trial

Bleeding Episodes:

  • Date, location, severity (1-4 scale)
  • Treatment used (product, dose, response)
  • Time to resolution
  • Any complications or hospitalizations

Treatment Burden:

  • Frequency of dosing
  • Administration difficulties
  • Impact on quality of life
  • Adherence challenges

Laboratory Monitoring:

  • Factor levels achieved
  • Inhibitor titer changes
  • Any safety concerns

Clinical Outcomes:

  • Bleeding frequency compared to baseline

Strengthening Your Resubmission

After a documented trial period (typically 3-6 months), resubmit with:

  • Comparative analysis of bleeding rates

  • Updated medical necessity letter
  • Any new clinical evidence or guideline updates

The key is demonstrating that alternatives were genuinely tried but proved inadequate for your specific clinical situation.

FAQ

How long does Aetna (CVS Health) PA take in New York?
Standard PA decisions take 30-45 days. Expedited reviews (for urgent medical needs) must be completed within 72 hours. Submit complete documentation initially to avoid delays.

What if Hemlibra is non-formulary on my specific plan?
Request a formulary exception with medical necessity documentation. Non-formulary doesn't mean non-covered—it typically means higher cost-sharing and additional approval requirements.

Can I request an expedited appeal in New York?
Yes. If delay poses serious risk to your health, both Aetna and New York DFS offer expedited review processes with 72-hour timelines (24 hours for urgent drug denials through DFS).

Does step therapy apply if I've failed treatments outside New York?
Prior treatment history from any location should count toward step therapy requirements. Ensure your new provider has complete records from previous physicians.

What happens if my appeal is denied?
After exhausting Aetna's internal appeals, you can request external review through New York DFS. Their decision is binding on the insurer and has a good success rate for medically appropriate requests.

How much does Hemlibra cost with Aetna coverage?
Costs vary by plan. Specialty drugs typically fall on higher formulary tiers. Check for manufacturer copay assistance programs and patient foundation grants to reduce out-of-pocket expenses.

Can I switch back to factor VIII if Hemlibra doesn't work?
Yes, but coordinate carefully with your hematologist. Monitor for inhibitor development and ensure proper transition timing to avoid bleeding risks.

What if I move to another state?
Your Aetna coverage should continue, but appeal rights and external review processes vary by state. Research your new state's insurance appeal laws before moving.
