Trader consensus on Polymarket reflects a 56% implied probability of no FDA approval for Sanofi's Tzield (teplizumab-mzwv) sBLA seeking to expand its label to delay stage 2 type 1 diabetes progression in children as young as 1 year old, driven by the absence of new developments in the past 30 days ahead of the April 29 PDUFA target action date. The filing earned priority review on January 5, 2026, supported by positive interim safety and pharmacokinetic data from the PETITE-T1D phase 4 trial showing good tolerability in young patients, yet lingering caution stems from mid-January reports of FDA delays on related Tzield expansions citing safety concerns, including a treatment-related death. No leaks or updates signal imminent approval, heightening uncertainty for this CD3-directed monoclonal antibody in the competitive type 1 diabetes space.

As of market creation, the FDA's expected decision date for the specified application is April 29, 2026.
This market will resolve to "Yes" if the U.S. Food and Drug Administration (FDA) grants full or conditional approval for Sanofi's Tzield as a treatment for delaying the onset of stage 3 type 1 diabetes in patients aged 1 year and older with stage 2 type 1 diabetes by May 13, 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.Trader consensus on Polymarket reflects a 56% implied probability of no FDA approval for Sanofi's Tzield (teplizumab-mzwv) sBLA seeking to expand its label to delay stage 2 type 1 diabetes progression in children as young as 1 year old, driven by the absence of new developments in the past 30 days ahead of the April 29 PDUFA target action date.
