The Phase 3 trial is a randomized, double-blind, placebo-controlled trial investigating the efficacy, safety, and tolerability of buntanetap. The trial will enroll a total of 450 early PD patients to be treated with 10mg buntanetap, 20mg buntanetap or a placebo, on top of their standard of care for six months.
Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II and III will be used as primary endpoints, while total MDS-UPDRS and Participant Global Impression of Change will be secondary endpoints. In addition, Wechsler Adult Intelligence Scale, plasma biomarkers and Mini-Mental State Examination will be evaluated as exploratory endpoints.
The Company previously reported results from its Phase 2a study of buntanetap in PD patients, which were treated with 5mg, 10mg, 20mg, 40mg or 80mg daily with no clinically significant adverse events. Additionally, treatment with buntanetap resulted in statistically significant improvement in motor function and its pharmacokinetics were found to be in line with levels measured earlier in humans, meeting both the primary and secondary endpoints.
Maria L. Maccecchini, Ph.D., Founder, President, and CEO of Annovis Bio said: "Buntanetap has shown promising preliminary safety data in all clinical work to date. Just as encouraging is the significant improvement in speed of movement, motor function and cognitive function observed in early to moderate PD patients treated with buntanetap in the Phase 2a trial. Now, as we officially advance buntanetap into a Phase 3 trial, with a longer treatment duration and a dose range shown to be efficacious in early studies, we are one step closer to delivering a solution that can transform the lives of patients with Parkinson's Disease."
Buntanetap (previously known as ANVS401 or Posiphen) is an oral translational inhibitor of neurotoxic aggregating proteins (TINAPs), which mode of action leads to lower levels of neurotoxic proteins and consequently less toxicity in the brain. In a Phase 2a clinical trial in AD and PD patients, treatment with buntanetap resulted in statistically significant improvement in motor function in PD patients and cognition in AD patients. Additionally, buntanetap was shown to reduce biomarkers associated with AD or PD, it was well-tolerated and safe, and its pharmacokinetics were found to be in line with levels measured earlier in humans, meeting primary, secondary and exploratory endpoints.
About Annovis Bio, Inc.
Headquartered in Berwyn, Pennsylvania, Annovis Bio, Inc. is a late-stage clinical drug platform company developing transformative therapies that treat neurodegenerative disorders such as Alzheimer's disease (AD), Parkinson's disease (PD) and other chronic and acute neurodegenerative diseases. The Company believes that it is the only company developing a drug that inhibits more than one neurotoxic protein, improves the information highway of the nerve cell, known as axonal transport, reduces inflammation and protects nerve cells from dying in chronic and acute neurodegeneration. Annovis conducted two Phase 2 studies: one in AD patients and one in both AD and PD patients. In the AD/PD study, buntanetap showed improvements in cognition and memory in AD as well as body and brain function in PD patients.
