Set Your Goal: What Approval Requires

Getting Zanzalintinib (XL092) covered by Aetna CVS Health in New York requires understanding that this isn't a typical prior authorization—it's an investigational drug approval process that demands exceptional documentation.

Your partnership with your oncologist centers on two parallel tracks:

  1. Compassionate Use Access: Your doctor must apply to Exelixis for expanded access via FDA Form 3926, demonstrating you're ineligible for clinical trials but have exhausted standard options.
  2. Insurance Coverage: Even with compassionate use approval, Aetna must separately approve coverage, typically requiring proof that standard therapies have failed and this represents your best remaining option.
Note: Unlike approved drugs where prior authorization focuses on formulary placement, investigational drugs require proving medical necessity under "experimental/investigational" policies that vary by plan.

Visit Preparation: Building Your Case

Come to your appointment prepared to document why Zanzalintinib represents your best option. Your oncologist needs specific details to build a compelling case.

Prepare Your Treatment Timeline:

  • List every cancer treatment you've tried, with start/stop dates
  • Document why each treatment was discontinued (progression, intolerance, contraindication)
  • Note any dose reductions or treatment delays
  • Include supportive care medications that failed

Symptom and Functional Impact Documentation:

  • Current symptoms affecting daily activities
  • ECOG performance status changes over time
  • Quality of life impacts from disease progression
  • Any urgent medical needs requiring expedited review

Bring These Documents:

  • Complete pathology reports with molecular testing results
  • Recent imaging showing disease progression
  • Laboratory results demonstrating organ function
  • Prior treatment records from other oncologists
  • Insurance denial letters if you've already attempted coverage
Tip: Request copies of all clinic notes from your visit—you'll need these for appeals documentation.

Evidence Kit Assembly

Your oncologist will need comprehensive evidence to support both the compassionate use application and insurance coverage request. Help them gather:

Clinical Evidence:

  • Biomarker testing confirming your cancer type matches Zanzalintinib's targets
  • Imaging demonstrating measurable disease progression
  • Documentation of ECOG performance status 0-2 (required for compassionate use)
  • Proof of adequate organ function for treatment safety

Treatment History Documentation:

  • Detailed records of all prior therapies with specific reasons for failure
  • Evidence of contraindications to standard alternatives
  • Documentation of treatment-related toxicities requiring discontinuation

Literature Support:

Counterforce Health specializes in assembling exactly this type of evidence package, helping patients and providers identify the strongest clinical and literature support for investigational drug appeals.

Medical Necessity Letter Structure

Your oncologist's medical necessity letter serves as the foundation for both compassionate use and insurance approval. Here's the essential structure:

Header and Patient Information:

  • Clear statement: "Requesting coverage for Zanzalintinib (XL092) for [specific diagnosis]"

Clinical Rationale Section:

  1. Diagnosis and Staging: Include primary diagnosis, date of diagnosis, current staging, and molecular characteristics
  2. Prior Treatment History: Chronological list of all therapies tried, duration, response, and reason for discontinuation
  3. Current Clinical Status: Recent labs, imaging, performance status, and disease progression evidence
  4. Treatment Justification: Why Zanzalintinib is medically necessary given exhausted standard options

Supporting Evidence:

  • Citations to clinical trial data showing efficacy
  • References to FDA guidance on compassionate use
  • NCCN guideline excerpts showing standard options are exhausted
  • Peer-reviewed literature supporting the treatment approach

Monitoring and Safety Plan:

  • Proposed dosing regimen and administration schedule
  • Laboratory monitoring plan for toxicity management
  • Response assessment timeline with imaging intervals
Clinician Corner: Include specific language like "no reasonable alternative exists" and "potential benefit outweighs risks"—these phrases align with both FDA compassionate use criteria and insurance medical necessity standards.

Peer-to-Peer Support

FAQ

How long does Aetna prior authorization take for investigational drugs? Standard prior authorization decisions take 30-45 days, but investigational drugs often require additional clinical review. Request expedited review (72 hours) if your oncologist can document urgent medical need.

What if Zanzalintinib isn't on Aetna's formulary? Investigational drugs typically aren't on formularies. You'll need to request a formulary exception based on medical necessity and lack of covered alternatives.

Can I appeal if I've failed treatments outside New York? Yes. New York appeals accept treatment history from any location. Ensure your oncologist documents all prior therapies with specific failure reasons.

Does Aetna require step therapy for investigational drugs? Step therapy requirements vary by plan, but investigational drugs typically bypass standard step therapy if you can demonstrate failure of or contraindications to all approved alternatives.

What happens if my external appeal is approved? Aetna must cover the treatment and refund your $25 appeal fee. The decision is binding and cannot be overturned by the insurance company.

How do I find similar cases in the NY appeals database? Search the DFS database using terms like "investigational drug," "experimental treatment," or your specific cancer type to find precedent decisions.

Can I get help with the compassionate use application? Yes. Contact Exelixis directly through their medical information department, or work with patient advocacy organizations that specialize in expanded access applications.

What if my oncologist is hesitant to pursue compassionate use? Request a second opinion or ask for referral to an oncologist experienced with investigational drug access. Some cancer centers have dedicated expanded access coordinators.


From Our Advocates: We've seen patients successfully obtain coverage for investigational TKIs by emphasizing the "no reasonable alternative" standard in their appeals. One patient's case was strengthened by including a detailed timeline showing progression through every NCCN-recommended therapy, plus molecular testing results that specifically supported the investigational drug's mechanism. The key was demonstrating that standard care had truly been exhausted, not just that the investigational option seemed promising.
