Gothenburg, Sweden, February 20, 2026. IRLAB Therapeutics (Nasdaq Stockholm: IRLAB A), a company discovering and developing novel treatments for Parkinson’s disease, today announced that its scientific advisory board has provided important guidance on the continued development and plans for its drug candidate, pirepemat. The advisory board concludes that the pharmacological rationale for pirepemat is sensible and that the reduction in falls observed in the Phase IIb trial is clinically meaningful, warranting further development.
Gothenburg, Sweden, February 20, 2026. IRLAB Therapeutics (Nasdaq Stockholm: IRLAB A), a company discovering and developing novel treatments for Parkinson’s disease, today announced that its scientific advisory board has provided important guidance on the continued development and plans for its drug candidate, pirepemat. The advisory board concludes that the pharmacological rationale for pirepemat is sensible and that the reduction in falls observed in the Phase IIb trial is clinically meaningful, warranting further development.
In late December 2025, IRLAB arranged a scientific advisory board meeting to assess the results from its Phase IIb clinical study of pirepemat (REACT-PD) and discuss next steps in the development plan for the drug candidate. The advisory board comprises four esteemed key opinion leaders (KOLs) from North America, Europe and Scandinavia, recognized for their expertise in Parkinson’s disease with special focus on falls, complications related to falls and the underlying mechanisms.
The members unanimously agreed that falls among patients are a significant unmet medical need in Parkinson’s care, with no available pharmaceutical treatment. The advisory board highlighted that the occurrence of falls is a key clinical indicator and should remain a primary focus in upcoming clinical studies. The decrease in fall occurrences observed in the Phase IIb study was considered highly clinically meaningful. Furthermore, the pharmacologic rationale and mechanism of action of pirepemat are deemed compatible with a biphasic concentration–response relationship. The advisory board concluded that pirepemat is a promising candidate to offer meaningful therapeutic benefits and that further development is warranted.
"We are pleased to have convened such a distinguished group of Parkinson’s experts to guide the development of pirepemat. The feedback from our advisory board unanimously confirms the potential of pirepemat to address a treatment gap with profound consequences for patients' quality of life, and we remain committed to bringing this highly meaningful therapeutic option to people living with Parkinson’s disease and their loved ones,” says Nicholas Waters, Executive Vice President & Head of R&D.
