VQ-101 / Vanqua Bio - LARVOL DELTA

VQ-101 DEMONSTRATES SUSTAINED ACTIVATION OF LYSOSOMAL GLUCOCEREBROSIDASE (GCASE) IN PEOPLE WITH PARKINSON'S DISEASE (ADPD 2026) - "In individuals with PD, VQ-101 demonstrated favorable tolerability, full CNS penetrance, and sustained activation of GCase, consistent with previously reported data from HV. The patient PK and pharmacodynamics profiles support once/daily oral administration and demonstrate dose-dependent target engagement. These results, together with preclinical and HV data, support the potential for VQ-101 to slow or stop the progression of PD by increasing lysosomal GCase activity, re-establishing lysosomal homeostasis, and consequently blocking the accumulation of misfolded aSyn."

Vanqua Bio to Present at the AD/PD 2026 International Conference (GlobeNewswire) - "The presentation will detail interim results from the ongoing Phase 1 clinical trial of VQ-101 in healthy volunteers and people with Parkinson’s disease (PD). The Phase 1b portion of the trial consists of a randomized, double-blind, placebo-controlled one-month dosing period followed by an optional open-label extension. In GBA-Parkinson’s patients, VQ-101 achieved robust peripheral and central exposure, was well tolerated, and demonstrated sustained activation of live-cell lysosomal GCase by more than 50%....The open-label extension portion of the study is expected to be completed in mid-2026. Vanqua looks forward to sharing additional data on idiopathic Parkinson’s subjects...at future medical meetings."

The Small Molecule VQ-101 Demonstrates Sustained Lysosomal Glucocerebrosidase (GCase) Activation in Idiopathic Parkinson's Disease (AAN 2026) - "Consistent with previously reported data in GBA-PD, VQ-101 confirmed its favorable safety profile, full CNS penetrance, and sustained activation of GCase in iPD individuals. These results, together with preclinical data, support the potential for VQ-101 to slow or stop the progression of PD by increasing lysosomal GCase activity, restoring lysosomal function, and consequently blocking the accumulation of misfolded aSyn."

VQ-101, a CNS-Penetrant Small Molecule Allosteric Activator of Glucocerebrosidase (GCase), Demonstrates Favorable Tolerability and Sustained Activation of Lysosomal GCase in Individuals with Parkinson's Disease (MDS Congress 2025) - "VQ-101 was well tolerated at all dose levels evaluated in both HVs and participants with PD, with and without a GBA1 mutation. VQ-101 has a favorable CSF and plasma PK profile, supporting once daily oral dosing and demonstrated dose-dependent target engagement. These results, together with preclinical data, support the potential for VQ-101 to slow or stop the progression of PD by increasing GCase activity and blocking the accumulation of misfolded aSyn."

Vanqua Bio Highlights Positive Interim Data from its Ongoing Phase 1b Clinical Trial of VQ-101, an Allosteric Activator of GCase for the Treatment of GBA-Parkinson’s and Related Disorders, at The International Congress of Parkinson’s Disease and Movement Disorders (GlobeNewswire) - "Following 28 days of dosing, VQ-101 exceeded the study’s target engagement goal, 50% lysosomal GCase activation, at all doses tested....Consistent with the robust target engagement observed in the study, VQ-101 demonstrated a favorable safety and pharmacokinetics profile. No dose-limiting or serious adverse events were reported, and all treatment-emergent adverse events were mild or moderate in severity....The open label extension portion of the Phase 1b study in Parkinson’s patients is ongoing; additional data are expected in early 2026."

VQ-101 has a favorable CSF and plasma PK profile, supporting once daily oral dosing and demonstrates dose-dependent target engagement in HVs. These results, together with preclinical data, support the potential for VQ-101 to slow or stop the progression of PD by increasing GCase activity and blocking the accumulation of misfolded aSyn."

Vanqua Bio Announces Positive Interim Results from Phase 1 Clinical Trial of VQ-101, an Orally Administered, Brain-Penetrant, Allosteric Activator of GCase for the Treatment of GBA-Parkinson’s and Related Disorders (GlobeNewswire) - "In healthy volunteers, VQ-101 activated lysosomal GCase by more than 75% in single dose cohorts, and activation was sustained following multiple doses. This exceeded the study’s target engagement goal of 50% activation...In addition to robust target engagement, VQ-101 achieved significant levels in the CSF; the mean CSF:unbound plasma ratios were ≥1, indicating full central nervous system penetrance. Lastly, in both the single and multiple ascending dose cohorts of this Phase 1a study, VQ-101 was well-tolerated, with no dose-limiting or serious adverse events reported. All treatment-emergent adverse events were mild or moderate in nature and there were no study discontinuations due to adverse events."
