REDWOOD CITY, Calif., Feb. 22, 2024 (GLOBE NEWSWIRE) -- Ashvattha Therapeutics (“Ashvattha”), a clinical-stage company advancing a new class of nanomedicine therapeutics that traverse tissue barriers to selectively target activated cells in regions of inflammation, today announced that the first patient has been enrolled in its expanded Phase 1/2 study of 18F-OP-801, a hydroxyl dendrimer (HD) imaging agent. The study will evaluate the safety, pharmacokinetics and biodistribution of an intravenously administered dose of 18F-OP-801 in patients with amyotrophic lateral sclerosis (ALS), Alzheimer’s disease (AD), multiple sclerosis (MS) and Parkinson’s disease (PD). “This study builds on preclinical data which demonstrated 18F-OP-801's ability to cross the blood-brain barrier and be taken up by activated microglia in regions of neuroinflammation in multiple disease models. We have already demonstrated in the first part of this clinical trial that there is no appreciable uptake in the brains of healthy volunteers, as expected. Our focus now turns to enrolling subjects with neurodegenerative conditions to determine the uptake of 18F-OP-801 in regions of neuroinflammation to support the use of this agent as a companion biomarker for one of our HD therapeutics,” said Jeffrey Cleland, Ph.D., Chairman, President, and CEO of Ashvattha Therapeutics. “We look forward to evaluating imaging data in this study over the next several months and also expect to have initial results from our Phase 2 trial of D-4517.2 in patients with wet AMD and DME in the first half of 2024.” The Phase 1/2 study will initially enroll up to 20 subjects with ALS, AD, MS, and PD. In addition to evaluating the safety and tolerability of 18F-OP-801, major objectives of the study are to measure the biodistribution and clearance of 18F-OP-801 and to evaluate its ability to detect regions of neuroinflammation via PET imaging in subjects with disease compared to age-matched healthy volunteers. Additional objectives include determining the correlation between PET imaging signal, biomarkers of disease activity and clinical disease assessments. The study will also assess test/retest repeatability of 18F-OP-801 uptake in a subset of subjects.
