Spruce Biosciences terminated its collaboration and license agreement with Kaken Pharmaceutical for tildacerfont in Japan, effective March 31, 2026, eliminating rights to up to approximately $65.0 million in potential milestone payments and future royalties, though no early termination penalties apply.
The company reported full-year 2025 net loss of $39.0 million, improved from $53.0 million in 2024, as total operating expenses fell to $36.5 million from $61.1 million, driven by ending tildacerfont development and focusing on tralesinidase alfa enzyme replacement therapy (TA-ERT) for Sanfilippo syndrome type B.
Cash and cash equivalents were $48.9 million as of December 31, 2025, and a loan facility with Avenue Capital provides up to $50 million, including an initial funded tranche of $15 million. Positive FDA Type B meetings support a planned biologics license application for TA-ERT in the fourth quarter of 2026, and new commercial and development leaders were added ahead of a potential launch.

Spruce Biosciences, Inc. entered a new Open Market Sale agreement with Jefferies that allows at‑the‑market issuances of common stock under its existing shelf registration, replacing a 2022 sales agreement.

For 2025, Spruce reported cash and cash equivalents of $48.9 million as of December 31, 2025, excluding $15.0 million of loan proceeds received in January 2026, and expects this cash to fund operations into early 2027.

Total operating expenses declined to $36.5 million from $61.1 million, and net loss narrowed to $39.0 million from $53.0 million.

Spruce Biosciences files its Annual Report outlining a high‑risk but focused rare‑disease strategy and a challenging financial position. The company highlights substantial doubt about its ability to continue as a going concern and says it lacks sufficient working capital for the next twelve months without new funding.
Its lead program, TA‑ERT, targets ultra‑rare MPS IIIB, where no FDA‑approved therapies exist. Long‑term studies showed normalization of key biomarkers and stabilization of cognitive function, and the FDA has agreed that CSF HS‑NRE may support accelerated approval if a confirmatory Phase 3 trial is started during biologics license review. Spruce is preparing a BLA submission, now anticipated in late 2026.
The report also details earlier‑stage assets, including tildacerfont with the Cortibon diagnostic for major depressive disorder, where a Phase 2 trial was discontinued after a serious liver enzyme elevation, and SPR202 for congenital adrenal hyperplasia, licensed from HBM with milestones up to $390.0 million. As of June 30, 2025, non‑affiliate common stock held a market value of about $2.8 million, and 1,372,043 shares were outstanding as of March 3, 2026; these figures frame the small scale of the company against its extensive development and licensing obligations.
