Biologics License Application (BLA) for TA-ERT for the Treatment of MPS IIIB Anticipated in the Fourth Quarter of 2026
TrAnsform Confirmatory Study Required for Potential FDA Accelerated Approval of TA-ERT Expected to Initiate in the Fourth Quarter of 2026
Strengthened Leadership Team with the Appointments of Adrian Quartel, M.D., FFPM, as Chief Medical Officer and Jessica Cohen Pfeffer, M.D., as Vice President, Clinical Development
“The second quarter was a period of significant execution as we advanced TA-ERT toward our planned BLA submission in the fourth quarter, which would be a transformative milestone for Spruce and for the children and families living with MPS IIIB,” said Javier Szwarcberg, M.D., M.P.H., Chief Executive Officer of Spruce Biosciences. “As we prepare for the submission, we are also preparing to initiate our TrAnsform confirmatory study in the fourth quarter of 2026. We are honored and grateful that Cure Sanfilippo Foundation and the National MPS Society have made a combined
TA-ERT Program Updates
- BLA submission for TA-ERT for the treatment of MPS IIIB anticipated in the fourth quarter of 2026: Spruce continues to advance manufacturing readiness, regulatory interactions and commercial planning to support an anticipated BLA submission in the fourth quarter of 2026, seeking accelerated approval based on cerebrospinal fluid heparan sulfate non-reducing end (CSF HS-NRE) as a reasonably likely surrogate endpoint of clinical benefit. There is currently no FDA-approved therapy for the treatment of MPS IIIB, and disease management consists of limited palliative care.
- TrAnsform confirmatory study required for potential FDA accelerated approval of TA-ERT expected to initiate in the fourth quarter of 2026: The planned TrAnsform confirmatory study is a randomized, single-blind, parallel-group, controlled, multicenter study evaluating the safety, tolerability and efficacy of intracerebroventricular (ICV)-administered TA-ERT compared to standard of care in children 1 to 5 years of age with severe (non-attenuated) MPS IIIB. The study is expected to enroll approximately 14 participants, with the primary objective of evaluating the effect of TA-ERT on cognition. As a condition of potential FDA accelerated approval of TA-ERT, the FDA requested that the company initiate the TrAnsform confirmatory study while the planned BLA submission for TA-ERT is under review. More information about the TrAnsform confirmatory study can be found at ClinicalTrials.gov.
Strengthening Clinical Development and Medical Leadership
During and subsequent to the quarter, Spruce further strengthened its clinical development and medical leadership with two senior appointments to support the planned TA-ERT BLA submission, potential FDA approval and commercial readiness:
- Adrian Quartel, M.D., FFPM, Chief Medical Officer: Dr. Quartel was appointed Chief Medical Officer effective July 27, 2026. He brings more than 25 years of international pharmaceutical experience across clinical development, pharmacovigilance and medical affairs, with a track record of advancing and launching enzyme replacement therapies for rare diseases. He joins Spruce from Zevra Therapeutics, where he served as Chief Medical Officer, and previously served as Chief Medical Officer of Acer Therapeutics and of Adamas Pharmaceuticals. Earlier, as Group Vice President of Global Medical Affairs at BioMarin Pharmaceutical, he helped lead the launch of six treatments for rare diseases and genetic disorders, including the enzyme replacement therapies NAGLAZYME®, VIMIZIM® and Brineura® (cerliponase alfa).
- Jessica Cohen Pfeffer, M.D., Vice President, Clinical Development: Dr. Cohen Pfeffer was appointed Vice President, Clinical Development effective August 3, 2026. She brings more than a decade of biopharmaceutical experience across clinical development, product portfolio development and medical affairs, including a track record of supporting global regulatory approvals for enzyme replacement therapies for rare pediatric neurodegenerative disorders. She joins Spruce from BioMarin Pharmaceutical, where she most recently served as Executive Medical Director and clinical sciences lead for Brineura® (cerliponase alfa).
Strategic Investment from the Patient Advocacy Community
Today, Spruce separately announced that Cure Sanfilippo Foundation and the National MPS Society have made a combined
Second Quarter 2026 Financial Results

for the second quarter of 2026 and$12.2 million for the first six months of 2026, compared to$19.7 million for the first six months of 2025. The increase was primarily attributable to increased expenses to advance TA-ERT, including manufacturing scale-up and clinical development, partially offset by lower one-time product acquisition costs and the discontinuation of the tildacerfont congenital adrenal hyperplasia development program.$10.4 million -
General and Administrative (G&A) Expenses: G&A expenses were
for the second quarter of 2026 and$4.3 million for the first six months of 2026, compared to$8.8 million for the first six months of 2025.
