VQ-101, an allosteric activator of lysosomal glucocerebrosidase, demonstrates sustained target engagement and pathway engagement in patients with Parkinson’s disease (WPC 2026) - "In patients with PD with and without a GBA1 mutation, VQ-101 demonstrated favorable tolerability, full CNS penetrance, sustained target engagement, and significant pathway engagement. This is the first demonstration of combined target and pathway engagement for a GCase-targeted therapeutic in patients with PD."

Vanqua Bio…announced that the company will present interim data from its Phase 1b study at World Parkinson’s Congress and the GBA1 Meeting 2026 (GlobeNewswire) - "The presentations will detail interim results from the ongoing Phase 1 clinical trial of VQ-101 in healthy volunteers and patients 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. VQ-101 displayed a very promising profile in patients with PD, with and without a GBA1 mutation. Following chronic dosing, VQ-101 achieved robust peripheral and central exposure, was well tolerated, and demonstrated sustained activation of live-cell lysosomal GCase....The open-label extension portion of the study is expected to be completed mid-2026."

AAN 2026: VQ-101 reaches the brain, hits target in diverse Parkinson’s patients (Parkinson's News Today) - "In the Phase 1a part, which involved healthy volunteers, VQ-101 was well tolerated and increased GCase activity by more than 75%. More recently, data from participants with GBA-related Parkinson’s in the Phase 1b part showed that the therapy boosted GCase activity to levels seen in healthy people...Across healthy volunteers and Parkinson’s patients dosed in the study, the therapy has shown a 'very favorable safety profile,' according to the physician. The majority of side effects have been mild, and none have been serious...In Parkinson’s patients, the medication reached high levels in the cerebrospinal fluid that surrounds the brain and spinal cord, suggesting that the therapy gets into the brain as intended....Vanqua is planning on a longer-term clinical trial that could be launched as early as next year."

The Small Molecule VQ-101 Demonstrates Sustained Lysosomal Glucocerebrosidase (GCase) Activation in Idiopathic Parkinson’s Disease (AAN 2026) - "Conclusions 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 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."

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."
