**Trader consensus strongly favors "No" at 98.3% implied probability following the U.S. Food and Drug Administration's extension of the Prescription Drug User Fee Act date for Sanofi's subcutaneous Sarclisa (isatuximab) from April 23 to July 23, 2026, announced April 22.** This delay stems from additional review needs for the on-body injector delivery system in the biologics license application, which seeks approval for the CD38 monoclonal antibody in relapsed/refractory multiple myeloma indications matching the approved intravenous formulation, supported by pharmacokinetic bridging studies demonstrating bioequivalence. No approval decision emerged by the original PDUFA deadline, solidifying trader confidence amid routine FDA extensions for novel delivery methods. Realistic shifts could arise from accelerated review or unexpected early positive data release, though official guidance underscores ongoing evaluation uncertainties prior to the new target date.

This market will resolve to "Yes" if the U.S. Food and Drug Administration (FDA) grants full or conditional approval for Sanofi’s Subcutaneous Sarclisa as a treatment for multiple myeloma by May 7, 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.
