Annovis Provides Corporate Updates and Second Quarter 2026 Financial Results

·Pivotal Phase 3 Alzheimer’s disease (AD) trial is fully enrolled with a total number of 850 patients, exceeding original projections.

·Parkinson’s disease (PD) open-label extension (OLE) study has enrolled 266 patients with full enrollment projected in Q4 2026.

·Annovis will host a corporate update webinar on Wednesday, September 2, 2026, at 4:00 pm EDT.

Malvern, PA, August 14, 2026 -- Annovis Bio, Inc. (NYSE: ANVS) (“Annovis” or the “Company”), a Phase 3 clinical-stage biotechnology company developing the investigational oral therapy, buntanetap, for neurodegenerative diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD), today provided business updates and reported financial results for the second quarter ended June 30, 2026.

“Our company witnessed major clinical strides during the second quarter,” said Maria Maccecchini, Ph.D., President and CEO of Annovis. “We reached an important milestone – full enrollment of our pivotal Phase 3 study in early AD – having recruited 850 patients. This number tells us how urgently patients and families need new options and underscores their faith in our approach to treating AD. We also plan to continue the ongoing study with an open-label extension (OLE) so AD patients can continue buntanetap treatment after finishing the trial. With topline data on track for early 2027, our team has already begun preparing for regulatory submission so that we are ready to move once the results are in hand.”

Clinical highlights

Alzheimer’s disease – pivotal Phase 3 trial

·Enrollment: The trial is fully enrolled with 850 patients, exceeding the original target enrollment number of 760 patients.

·Patients: The pivotal Phase 3 AD trial includes patients diagnosed with early AD (MMSE 20-28) who are also positive for plasma pTau217 biomarker, confirming the presence of amyloid and tau pathology in the brain.

·Study design: The study measures cognition (ADAS-Cog13) and function (ADCS-iADL) as co-primary endpoints, supported by volumetric MRI, pTau217, and other biomarkers to evaluate changes in disease pathology. The study is designed to test both symptomatic (6 months) and disease-modifying (18 months) effects of buntanetap.

·Timeline: The Company plans a database lock for the 6-month analysis in Q1 2027, with the top-line symptomatic data readout anticipated in the same quarter. The disease-modifying data readout is expected a year later.

Alzheimer’s disease – OLE study

·Start: The AD OLE study is expected to initiate in October 2026.

·Aim and patients: The AD OLE study will allow patients who are currently in the pivotal Phase 3 trial to receive buntanetap after completing their 18-month treatment period. Patients from both arms – buntanetap and placebo – will be allowed to join. The initiation of the AD OLE is timed to coincide with the first patient finishing their 18-month treatment, ensuring seamless transition into the extension study. The AD OLE will also be open to participants from Annovis’ prior AD clinical trials.

Parkinson’s disease – OLE study

·Enrollment: The study has so far enrolled 266 patients toward its estimated enrollment goal of 500. It accepts participants who were in prior Annovis’ clinical trials as well as new patients who have deep brain stimulation (DBS).

·Site activation: 26 clinical sites have been activated across the US.

·Study design: The PD OLE study is designed to evaluate buntanetap's safety and long-term efficacy over the period of 36 months, supported by NeuroRPM, a real-time digital biomarker that measures core PD symptoms, and a skin biopsy test for alpha-synuclein pathology.

Corporate highlights

·Management: Annovis promoted Cheng Fang, Ph.D., to Chief Scientific Officer (CSO), where she will oversee the clinical execution and scientific advancement of buntanetap as the Company approaches key regulatory milestones.
