MALVERN, Pa., May 09, 2024 (GLOBE NEWSWIRE) -- Annovis Bio, Inc. (NYSE: ANVS) ("Annovis" or the "Company"), a clinical-stage drug platform company developing novel therapies for neurodegenerative diseases, today announced successful completion of data cleaning for its Phase III study of buntanetap in patients with early Parkinson's disease (PD). Topline efficacy data is expected in June.
The Phase III study was completed in 4Q 2023 with an original plan for data announcement in 1Q 2024, however the Company faced a delay in the process of data cleaning beyond the original prognosis. Maria Maccecchini, Ph.D., Founder, President, and CEO of Annovis, explains in detail the reason behind this delay:
"When we reached the point of unblinding the data for the PD Phase III study, we discovered an unexpected issue: too many plasma samples showed no presence of buntanetap. We were expecting 33% blank samples from the placebo group, but we saw over 50% blank samples. We were afraid that we had mixed up bottles and that patients weren't given what they were supposed to. If that had happened, the study would have been worthless. We promptly started searching for a possible explanation at every step of the way. We checked the content of the bottles - correct. We checked the distribution of the bottles - correct. We checked the labeling of the plasma samples - correct. We checked the distribution of the plasma samples - correct. So, we were left with the pharmacokinetic (PK) measurements. PK is measured by LC-MS/MS with a very expensive set of equipment under GLP, GCP, GMP, and is regulated by very strict FDA rules. It turns out that the group, which was evaluating the PK, modified the method, unfortunately affecting the measurements. We repeated the PK of the same samples and obtained an expected 33% of blank samples accounting for placebo.
The whole process took us 2 months, which caused the delay in data announcement. However, due to our effort and immediate actions, we are now confident and ready to evaluate the data for the public and the FDA and report topline results in June.
Thank you very much for your understanding and patience."
