Initial Funding of $15 Million from the First of Four Tranches, Extending Cash Runway into 2027

Facility Will Support Advancement and Potential Launch of TA-ERT for the Treatment of MPS IIIB

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Jan. 8, 2026-- Spruce Biosciences, Inc. (Spruce) (Nasdaq: SPRB), a late-stage biopharmaceutical company focused on developing and commercializing novel therapies for neurological disorders with significant unmet medical need, today announced that, on January 7, 2026, it entered into a loan facility with Avenue Venture Opportunities Fund II, L.P., a fund of Avenue Capital Group (Avenue Capital), for up to $50 million in growth capital.

The loan facility has a 42-month term and includes an initial tranche of $15 million, which will be fully funded on or around January 9, 2026, and three additional tranches totaling up to $35 million, the funding of which is subject to the satisfaction of certain terms and conditions of the loan and security agreement, including the achievement of key regulatory and commercial milestones related to the company’s development and planned commercial launch of tralesinidase alfa enzyme replacement therapy (TA-ERT) for the treatment of Sanfillipo Syndrome Type B (MPS IIIB).

“We are pleased to partner with Avenue Capital on a strategic financing agreement with attractive terms that strengthens our financial flexibility,” said Samir Gharib, President and Chief Financial Officer of Spruce Biosciences. “At the drawdown of the initial $15 million tranche, we expect our cash and cash equivalents to fund planned operations into 2027, supporting the biologics license application (BLA) filing of TA-ERT for the treatment of MPS IIIB, while also accelerating pre-launch commercial activities.”

“We believe Spruce is well-positioned to advance and potentially launch TA-ERT as the first disease-modifying therapy to treat MPS IIIB, and we’re proud to be partnering with this outstanding team to advance that mission,” said Chad Norman, Senior Portfolio Manager at Avenue Capital. “With no FDA-approved treatments currently available to treat MPS IIIB, TA-ERT has the potential to be a groundbreaking advancement for patients and families impacted by this devastating disease.”

Armentum Partners acted as the company's exclusive financial advisor on this transaction.
