FDA Decision Calendar
Upcoming PDUFA target action dates, each one traced to the company press release that set it. Extensions are tracked on the row with the superseded date still visible, because a moved date repeated as current is the most common error on FDA calendars, and two of the widely syndicated dates were stale on the day this one launched.
When Is the Next FDA Decision?
CAPR (Capricor Therapeutics): the FDA's target action date for deramiocel in duchenne muscular dystrophy, refined to a proposed indication focused on upper limb function is November 22, 2026. A PDUFA date is a by-date rather than an on-date: the decision can arrive early, and a weekend date resolves by the preceding business day in practice.
Upcoming Decisions

Capricor Therapeutics · BLA (Class 2 resubmission, amended August 2026 and classified a major amendment) · Duchenne muscular dystrophy, refined to a proposed indication focused on upper limb function
Was: August 22, 2026
Advisory committee: Advisory committee voted 3-9 against on July 29, 2026, on the cardiomyopathy framing.
Extended three months from August 22 after Capricor submitted 24-month open-label extension data from the pivotal Phase 3 HOPE-3 study, plus robustness analyses, in support of a refined indication focused on upper limb function. The FDA classified the submission as a major amendment, which carries the standard three-month extension: August 22 plus three months is November 22, and the agency's own letter gives that date. November 22 is a Sunday, so the practical window closes with the preceding business day. The advisory committee's 3-9 vote of July 29 was taken on the cardiomyopathy framing, which is not the indication now under review.

Savara · BLA · Autoimmune pulmonary alveolar proteinosis
Was: August 22, 2026
Extended three months from August 22 after the FDA classed Savara's responses to information requests as a major amendment. The company announced the extension on April 15, 2026, and the FDA cited no safety, efficacy or manufacturing concern. Several aggregator calendars still carry the old August date. November 22 is a Sunday, so the practical window closes with the preceding business day.

GSK plc (Nuvalent) · NDA · TKI pre-treated advanced ALK-positive non-small cell lung cancer
The second of the two Nuvalent decisions, and the one still pending. GSK completed its $10.6bn acquisition of Nuvalent on July 15, 2026, so NUVL no longer trades and this decision now sits with GSK. GSK's own release on the July 22 zidesamtinib approval restates the November 27 target decision date.

- November 30, 2026MondayCOGT: Bezuclastinib in combination with sunitinibPriority review
Cogent Biosciences · NDA · Gastrointestinal stromal tumors, second line, after prior imatinib
Advisory committee: FDA communicated no plan to hold an advisory committee.
The second of Cogent's three bezuclastinib applications. Aggregator calendars often attach this November 30 date to the non-advanced systemic mastocytosis row, which is a different application on December 30. Supported by the Phase 3 PEAK study: median progression-free survival of 16.5 months on the combination against 9.2 months on sunitinib alone, a hazard ratio of 0.50, with a 46% objective response rate against 26%. November 30 is a Monday. Cogent restated the date on September 15, 2026.

Cogent Biosciences · NDA · Non-advanced systemic mastocytosis
Advisory committee: FDA communicated no plan to hold an advisory committee and no review issues identified at acceptance.
Three bezuclastinib applications are under review at once, on three separate action dates, which is why aggregator calendars disagree about this one. This row is the non-advanced systemic mastocytosis NDA, and Cogent's own releases put it on December 30, 2026. The November 30 date that some calendars attach to this drug belongs to the GIST application, which is its own row here. The advanced systemic mastocytosis NDA was accepted on September 15, 2026 with a June 29, 2027 action date, which sits beyond this calendar's window.

Passed Dates
- October 10, 2026SaturdayMRK: Ifinatamab deruxtecan (I-DXd)Withdrawn
Merck / Daiichi Sankyo · BLA · Previously treated extensive-stage small cell lung cancer
Would have been a first-in-class B7-H3 directed antibody-drug conjugate. October 10 was a Saturday, so the practical window closed with the preceding business day. Daiichi Sankyo and Merck withdrew the application on September 25, fifteen days before the action date, after the FDA told them the Phase 2 IDeate-Lung01 response-rate data did not support accelerated approval. The Phase 3 IDeate-Lung02 trial, which compares I-DXd against physician's choice of chemotherapy, is still enrolling and is the route to any future filing.
FDA acted September 25, 2026: Daiichi Sankyo and Merck voluntarily withdrew the BLA on September 25 after discussions with the FDA, which held that the data supporting the application, including the Phase 2 IDeate-Lung01 trial, did not satisfy the requirements for accelerated approval in this indication. Not a complete response letter: the companies pulled the filing rather than take a decision on October 10. The Phase 3 IDeate-Lung02 trial continues and could support a later submission.

September 26 is a Saturday, so the practical window closes with the preceding business day, Friday September 25. Would be the first approved therapy for FOP, an ultra-rare disease with about 300 diagnosed patients in the US and 900 worldwide. Pivotal PROGRESS study reported a 99.9% reduction in new heterotopic-ossification lesions.
FDA acted September 25, 2026: Approved as Atebrioz (zilurgisertib), the first therapy for FOP, for adult and pediatric patients 12 years and older, to reduce the volume of total new heterotopic ossification.

Approved 58 days ahead of the September 18 action date. GSK completed its $10.6bn acquisition of Nuvalent on July 15, 2026, a week before the approval, so NUVL no longer trades and this row carries GSK. The ALK-selective sibling neladalkib follows on November 27.
FDA acted July 22, 2026: Approved as Jideytro (zidesamtinib) for adults with locally advanced or metastatic ROS1-positive non-small cell lung cancer who had received at least one prior ROS1 TKI. Overall response rate was 44% in the ARROS-1 trial, and 69% of responders were still responding at twelve months.

How This Is Built
A date only appears here once it has been read in the company's own press release or filing, linked on the row. Aggregator calendars are used to find candidates and never to establish a date, because they demonstrably lag extensions: on the day this page launched, two syndicated dates were three months and one month stale respectively. When the FDA extends a review, the row keeps both dates, so a reader who saw the old one can see what happened to it.
The calendar deliberately covers a curated set: decisions on names this site covers, plus the largest pending approvals. It is not an exhaustive list of every generic and supplemental application, and it does not need to be to answer the question readers bring to it.
The whole calendar is available as JSON and CSV, licensed CC BY 4.0, with the source link and status carried on every row.
PDUFA Date FAQ
- When is the next FDA decision date?
- CAPR (Capricor Therapeutics): the FDA's target action date for deramiocel in duchenne muscular dystrophy, refined to a proposed indication focused on upper limb function is November 22, 2026. A PDUFA date is a deadline for the FDA to act, not a promise of approval: the agency can approve, issue a complete response letter, or extend the review.
- What is a PDUFA date?
- The date by which the FDA has committed to act on a drug application, under the Prescription Drug User Fee Act. Standard review targets ten months from acceptance; priority review targets six. The FDA can approve, reject with a complete response letter, or extend the date, most commonly by three months when a late submission is classed as a major amendment.
- Do FDA decisions arrive exactly on the PDUFA date?
- No. The date is a by-date, not an on-date: decisions regularly land days or weeks early, and dates that fall on a weekend resolve by the preceding business day in practice. Approvals have also arrived after the stated date without any formal extension.
- Why do dates on this calendar differ from other FDA calendars?
- Because extensions move dates and most aggregators are slow to catch them. When this calendar launched, two of the widely syndicated dates were stale: Savara's molgramostim had been extended from August 22 to November 22, 2026, and Cogent's bezuclastinib date is December 30, 2026, per the company, not the November 30 some calendars carry. Every date here links the company press release that set it. Last updated October 1, 2026.
- What happens to a stock on a PDUFA date?
- A binary event: approval opens a commercial launch, a complete response letter sends the company back for more work, and the stock reprices on whichever arrives. The move is usually largest for single-asset companies where the drug is most of the market cap, and smallest for label expansions on already-approved drugs at large companies.
