Trader consensus on Polymarket reflects an 89.5% implied probability against FDA approval of AstraZeneca's camizestrant, driven by today's Oncologic Drugs Advisory Committee (ODAC) 6-3 vote rejecting its clinical benefit in HR-positive, HER2-negative advanced breast cancer with ESR1 mutations. FDA briefing documents highlighted deep skepticism over the SERENA-6 phase 3 trial's novel ctDNA-guided early switch design from aromatase inhibitors before radiographic progression, lack of overall survival data, uncertain long-term benefits, and potential cardiac toxicity signals. While ODAC votes predict FDA decisions with 97% concordance for initial approvals, the PDUFA date coincides today, leaving slim room for override amid these unresolved regulatory hurdles.

This market will resolve to "Yes" if the U.S. Food and Drug Administration (FDA) grants full or conditional approval for AstraZeneca's Camizestrant as a treatment for HR+/HER2- advanced or metastatic breast cancer with ESR1 mutation by May 14, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No."
An approval is defined as:
For new drugs: FDA issuance of an approval letter for a New Drug Application (NDA) or Biologics License Application (BLA)
For already-marketed drugs seeking new indications: FDA approval of a supplemental NDA (sNDA) or supplemental BLA (sBLA) for the specific indication referenced
For generic drugs: FDA approval of an Abbreviated New Drug Application (ANDA)
For biosimilars: FDA approval of a 351(k) application
The following constitute qualifying approvals:
Standard approval (traditional approval based on clinical benefit), Accelerated approval (based on surrogate endpoints), Approval with Risk Evaluation and Mitigation Strategy (REMS), Approval with restricted distribution or indication limitations, except compassionate use/expanded access programs
The following do not constitute qualifying approvals:
Approvable letters that require additional actions before approval
Tentative approvals pending patent or exclusivity expiration
FDA requests for additional information or studies
Extension of Prescription Drug User Fee Amendments dates
Approval for compassionate use or expanded access programs only
Approval only for export or for use outside the United States
Emergency Use Authorization (EUA) without full approval
Complete Response Letters (CRLs) indicating the application cannot be approved in its current form
This market will immediately resolve to "No" if the FDA issues a Complete Response Letter (CRL) or explicitly declines to approve the application. If the drug sponsor withdraws the application before the end of the specified period, the market will resolve to "No" immediately.
If the listed drug is approved before the end of the specified period, the market will resolve to "Yes," regardless of potential Advisory Committee votes against approval or later withdrawal of approval.
Conditional approvals may include post-marketing requirements or commitments and still qualify.
The primary resolution source will be official information from the FDA; however, a consensus of credible reporting will also be used.
