Into the first quarter of 2027 outlook
- NoteGossamer expects the combination of current cash, cash equivalents and marketable securities will be sufficient to fund its operating and capital expenditures into the first quarter of 2027.
- NoteThe Company intends to submit an NDA supported by one adequate and well-controlled study (Phase 3 PROSERA) plus confirmatory evidence (Phase 2 TORREY and supportive analyses) in September 2026.
- NoteIf accepted for filing, seralutinib could be eligible for an FDA approval decision in the third quarter of 2027.
What drove it
- Revenue associated with Gossamer's collaboration with Chiesi included $6.1 million of cost reimbursement revenue.
- The decrease in R&D expenses was primarily driven by lower costs associated with clinical trials for seralutinib.
- Gossamer and Chiesi agreed to terminate their Collaboration and License Agreement, and Gossamer reacquired worldwide development and commercial rights to seralutinib.
- The termination agreement required Chiesi to make a one-time $5 million payment to Gossamer, settling all outstanding and future obligations under the prior collaboration, including second quarter 2026 costs.
- Gossamer made no upfront cash payment to reacquire the rights.
- The termination dissolves the prior U.S. 50/50 profit share and returns ex-U.S. rights to Gossamer.
Concerns
- The FDA characterized the degree of statistical significance and the magnitude of the treatment effect observed in PROSERA as review issues rather than filing issues.
- The FDA’s ultimate determination on approvability will be made upon review of the complete NDA.
- The FDA may determine that the planned NDA does not qualify for filing.
- The Company’s future performance is dependent entirely on the success of seralutinib.
- Any path forward may require additional capital and other resources, which may not be available on reasonable terms, if at all, or may limit the commercial opportunity for seralutinib.
- Stockholders authorized the Board to effect a reverse stock split, with the timing and final ratio subject to Board approval.
What to watch
- Submission of the seralutinib NDA in September 2026.
- FDA acceptance for filing of the planned NDA.
- Potential FDA approval decision in the third quarter of 2027, if the NDA is accepted for filing.
- The Company's cash runway expectation into the first quarter of 2027.
- Board action on the timing and final ratio of a reverse stock split.
- The regulatory and commercial milestone payments and capped worldwide net-sales royalty payable to Chiesi.

- Gossamer exchanged approximately $181.1 million, or 90.5%, of the $200.0 million aggregate principal amount of 2027 Notes outstanding for approximately $65.2 million of new 7.50% Convertible Senior Secured First Lien Notes due 2030, together with equity securities and warrants.

Management, verbatim
We completed a productive Pre-NDA Type B meeting with the FDA, received the official minutes and remain on track to submit our NDA for seralutinib in PAH in September. We also reacquired worldwide rights to seralutinib and completed a convertible note exchange that substantially reduced our debt. We are in a better position today, and our focus remains on the work required to move seralutinib forward.
