When Alternatives to Haegarda Make Sense

Humana's formulary typically requires patients to try other HAE prophylaxis medications before approving Haegarda. This step therapy approach makes clinical and financial sense in many cases, as the alternatives may be equally effective with different administration routes or side effect profiles.

Key scenarios where alternatives are appropriate:

  • First-time prophylaxis patients without previous treatment failures
  • Patients preferring oral medication over subcutaneous injections
  • Those with injection site reaction concerns or needle phobia
  • Patients seeking less frequent dosing (lanadelumab every 2 weeks vs. Haegarda twice weekly)
Note: Step therapy doesn't mean you can't eventually get Haegarda—it means documenting why other options didn't work for your specific situation.

Typical HAE Prophylaxis Alternatives

Coverage at a Glance

Medication Route Frequency Humana Coverage Common Issues
Berotralstat (Orladeyo) Oral Daily Often preferred first-line GI side effects, QT prolongation risk
Lanadelumab (Takhzyro) Subcutaneous Every 2 weeks Covered with PA Injection site reactions
Haegarda Subcutaneous Twice weekly Requires step therapy More frequent injections

Primary Alternatives Humana May Require First

Berotralstat (Orladeyo)

  • Only oral HAE prophylaxis option
  • Daily dosing with food
  • Common side effects: abdominal pain, nausea, diarrhea
  • Requires EKG monitoring for QT prolongation in high-risk patients

Lanadelumab (Takhzyro)

  • Subcutaneous injection every 2 weeks
  • May allow dose interval extension after 6 months
  • Generally well-tolerated with injection site reactions as primary concern
  • Often preferred over Haegarda due to less frequent dosing

Pros and Cons Overview

Berotralstat (Orladeyo) Considerations

Advantages:

  • No injections required
  • No cold storage needs
  • Can be taken at home without training

Potential drawbacks:

  • Gastrointestinal side effects common (30-40% of patients)
  • Daily dosing requirement
  • Drug interactions with certain medications
  • Not suitable for patients with significant GI disease

Lanadelumab (Takhzyro) Considerations

Advantages:

  • Less frequent dosing than Haegarda
  • Strong efficacy data
  • May allow interval extension
  • Established safety profile

Potential drawbacks:

  • Subcutaneous injection required
  • Cold storage and specialty pharmacy coordination
  • Higher upfront cost per dose
  • Injection site reactions

When Haegarda May Be Preferred

  • Previous C1-INH experience: Patients stable on IV C1-INH (Cinryze) transitioning to self-injection
  • Berotralstat intolerance: Persistent GI side effects or contraindications
  • Lanadelumab failure: Inadequate response or injection site issues
  • Patient preference: Some prefer more frequent, smaller volume injections

Exception Strategy for Haegarda

  • ICD-10 codes: D84.1 (hereditary angioedema)
  • Family history if applicable

2. Step Therapy Documentation

  • Detailed trial history of berotralstat or lanadelumab
  • Specific reasons for failure: lack of efficacy, intolerable side effects, contraindications
  • Duration of trials and clinical outcomes
  • Hospital admissions or emergency visits during alternative therapy

3. Clinical Necessity for Haegarda

  • Why subcutaneous C1-INH is medically necessary
  • Contraindications to oral or other injectable options
  • Prior experience with C1-INH products if applicable
Clinician Corner: Include specific clinical details like attack frequency reduction goals, quality of life impacts, and references to FDA labeling for Haegarda's approved indications.

Supporting Evidence to Include

  • Recent clinic notes documenting HAE attacks and severity
  • Emergency department records showing breakthrough attacks on current therapy
  • Laboratory values confirming diagnosis
  • Documentation of injection training completion (if switching from oral therapy)

FAQ

How long does Humana prior authorization take in Illinois? Standard requests: 3-5 business days. Expedited requests for urgent medical needs: 24 hours. Humana PA timelines are consistent across states.

What if Haegarda is non-formulary on my plan? Request a formulary exception with medical necessity documentation. Your prescriber must show why formulary alternatives are inappropriate for your condition.

Can I request an expedited appeal if I'm having frequent attacks? Yes, if your prescriber documents that delays in treatment would seriously jeopardize your health. Both internal and external expedited appeals are available in Illinois.

Does step therapy apply if I failed these medications in another state? Yes, previous documented failures should satisfy step therapy requirements regardless of where they occurred. Ensure your prescriber includes complete treatment history.

What's the difference between a prior authorization and formulary exception? Prior authorization is required for covered drugs with restrictions. A formulary exception requests coverage for non-formulary medications or waiver of restrictions.

How much does Haegarda cost without insurance? Retail cost varies by weight-based dosing but typically ranges in the high four to five figures monthly. CSL Behring patient assistance programs may help with costs.

Can I get help with the appeals process in Illinois? Yes, contact the Illinois Department of Insurance Consumer Helpline at 877-527-9431 or the Illinois Attorney General's Health Care Helpline at 877-305-5145 for assistance with appeals.
