  • Performance status and overall clinical condition

Prior Treatment Failures:

  • Chronological list of previous therapies

  • Concomitant medication review

Peer-to-Peer Support Strategy

If your initial authorization is denied, your oncologist may request a peer-to-peer review with the insurance company's medical director.

Preparing Your Doctor

Offer to help by:

  • Providing availability windows when your doctor can take the call
  • Summarizing key points in a one-page brief
  • Gathering recent test results that support medical necessity

Key Discussion Points for Your Doctor

  • Urgency of treatment in relapsed/refractory AML
  • Lack of effective alternatives for FLT3-mutated disease
  • Patient-specific factors supporting Xospata use
  • Monitoring capabilities at your treatment center
From our advocates: "We've seen peer-to-peer reviews succeed when the treating oncologist emphasizes both the time-sensitive nature of AML and the specific molecular targeting that makes Xospata uniquely appropriate for FLT3-mutated disease. Having recent bone marrow results readily available during the call often helps demonstrate ongoing medical necessity."
