Annovis Bio, Inc. (NYSE: ANVS) ("Annovis" or the "Company"), a clinical-stage drug platform company addressing neurodegenerative diseases, today announced that the independent statistical group concluded that its Phase 2/3 AD study was sufficiently powered to continue as originally planned without the addition of patients. This phase 2/3 AD study is designed to enroll a total of 320 mild to moderate AD patients, who are randomly assigned to receive 7.5, 15, 30 mg of buntanetap or placebo once per day. The trial’s co-primary endpoints are the change from baseline to the end of treatment of Alzheimer’s Disease Assessment Scale-Cognitive Subscale 11 (ADAS-Cog11) and Alzheimer’s Disease Cooperative Study Clinician’s Global Impression of Change (ADCS-CGIC), which assess cognition and activities of daily living.

The Company has received the results of the pre-planned interim analysis conducted by an independent data analytics provider. The interim analysis was based on 107 patients at 6 weeks from all cohorts collectively and showed that the AD trial should continue as planned with the same trial size to maintain the statistical power for both co-primary endpoints.

The Company remains blinded to the Phase 3 trial and does not have safety or efficacy data from the trial. A separate safety interim analysis is in process and we expect that interim analysis to be released in two weeks.

Maria L. Maccecchini, Ph.D., Founder, President, and CEO of Annovis, commented: “Although we remain blinded to the data, results from this interim analysis supports our original statistical powering for enrolling 320 patients into the Phase 2/3 Alzheimer’s study. Therefore, sample size re-estimation for the study is not necessary, which in our view, may signal an emerging positive treatment effect in patients receiving buntanetap versus those receiving placebo after just 6 weeks of treatment. While the interim analysis does not mean that the trial will necessarily be successful, it does mean that the trial is powered for potential success.”

Update and projections of our ongoing activities:

Alzheimer’s disease

  • to date, 230 patients have been enrolled and 62 have finished the study;
  • safety interim analysis, conducted by the DSMB on October 18, will be released the week of October 23;
  • full enrollment anticipated in November;
  • completion of treatment expected in February 2024;
  • phase 2/3 data expected in March 2024.

Parkinson’s disease

  • to date, 305 patients have finished the study;
  • completion of study expected by the end of November;
  • phase 3 data expected in January 2024.

In addition to the ongoing clinical studies, we are also excited about the novel crystal form of buntanetap - ANVS402. We expect to discuss with the FDA the transition buntanetap to ANVS402 and the development of the new form. The bridge studies are expected to be completed in Q1 2024.

As we move forward with our advanced, clinical-stage AD and PD programs, we hope to demonstrate buntanetap’s unique ability to inhibit the accumulation of pro-inflammatory, neurotoxic proteins and potential to address unmet medical need across a number of neurodegenerative conditions and diseases.

About BuntanetapBuntanetap (previously known as ANVS401 or Posiphen) is an investigational, oral translational inhibitor of neurotoxic aggregating proteins (TINAPs), which mode of action is thought to lead to a lower level of neurotoxic proteins and consequently less toxicity in the brain. In a Phase 2a clinical trial in AD and PD patients, buntanetap was shown to be generally well-tolerated, and its pharmacokinetics were found to be in line with levels measured earlier in humans, meeting both the primary and secondary endpoints. Additionally, exploratory endpoints were also met, as treatment with buntanetap resulted in statistically significant improvement in motor function in PD patients and cognition in AD patients. Presently buntanetap is being studied in a Phase 3 early PD study and in a Phase 2/3 study in AD patients.

About Annovis Bio, Inc.Headquartered in Berwyn, Pennsylvania, Annovis Bio, Inc. (Annovis) is a clinical-stage, drug platform company addressing neurodegeneration, such as Alzheimer's disease (AD), Parkinson's disease (PD), and other chronic neurodegenerative diseases. We believe that we are the only company developing a drug for AD and PD that inhibits more than one neurotoxic protein and, thereby, improves the information highway of the nerve cell, known as axonal transport. When this information flow is impaired, the nerve cell gets sick and dies. 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.
