Annovis Bio, Inc. (NYSE:ANVS): Developing a Potential Disease-Modifying Therapy for Alzheimer's and Parkinson's

Published on September 24, 2024 | Ticker: ANVS

Annovis Bio, Inc. (NYSE:ANVS) is a clinical-stage drug platform company addressing neurodegeneration, such as Alzheimer's disease (AD) and Parkinson's disease (PD). The company's lead product candidate, Buntanetap, is a small molecule administered orally that is designed to attack neurodegeneration by entering the brain and inhibiting the translation of multiple neurotoxic proteins, thereby impeding the toxic cascade.

Business Overview

Annovis is developing Buntanetap to address the underlying mechanism of neurodegeneration in AD and PD. High levels of neurotoxic proteins, such as amyloid-beta (Aβ), tau, and alpha-synuclein, lead to impaired axonal transport, inflammation, and death of nerve cells, resulting in loss of cognition and motor function. Buntanetap is designed to lower these neurotoxic protein levels, thereby improving axonal transport, reducing inflammation, and ultimately preserving nerve cell function.

The company has completed two Phase 1/2 clinical studies in early AD and early PD patients, as well as a trial in early AD patients in collaboration with the Alzheimer's Disease Cooperative Study (ADCS). These studies demonstrated that Buntanetap was safe and well-tolerated, and also showed improvements in biomarkers and cognition in AD patients, as well as improvements in function in PD patients.

Based on the positive results from these trials, Annovis has initiated a Phase 3 study in early PD patients and a Phase 2/3 study in mild to moderate AD patients. The company recently reported interim analysis results for both studies, which allowed them to proceed with the studies as planned.

Financials

For the fiscal year ended December 31, 2023, Annovis reported an annual net loss of $56.2 million, with no revenue generated. The company's annual operating cash flow and free cash flow were both -$39.9 million.

In the first quarter of 2024, Annovis reported a net loss of $1.1 million. Research and development expenses decreased by $1.3 million compared to the prior year period, primarily due to timing of study costs. General and administrative expenses also decreased by $0.9 million, driven by lower stock-based compensation and professional fees.

The company's cash and cash equivalents balance as of March 31, 2024 was $3.1 million. Annovis believes that its existing cash, combined with the $0.8 million raised under its ELOC facility in May 2024, will be sufficient to fund operations into the fourth quarter of 2024. However, the company will need to raise substantial additional capital to complete the development and commercialization of its product candidates.

Liquidity

Annovis has financed its operations primarily through the issuance of common stock and warrants. As of March 31, 2024, the company had cash and cash equivalents of $3.1 million. The company's net cash used in operating activities was $7.0 million for the first quarter of 2024, a decrease of $4.6 million compared to the same period in the prior year.

In April 2024, Annovis entered into a Common Stock Purchase Agreement (ELOC) with an equity line investor, providing the company with the ability to offer and sell up to 2.1 million shares of common stock, subject to certain limitations. The company has already issued approximately 150,000 shares under the ELOC, resulting in net proceeds of $0.8 million.

Annovis expects its cash used in operating activities to remain elevated as it continues the development of its product candidates, including the ongoing Phase 3 study in early PD patients and the planned next Phase 3 study in AD patients. The company will need to raise substantial additional capital through public or private equity offerings, debt financings, or other financing alternatives to fund its operations and future clinical trials.

Risks and Challenges

Annovis faces several risks and uncertainties that could impact its business and financial performance. The company's ability to successfully develop and commercialize Buntanetap is dependent on the outcome of its ongoing and planned clinical trials. Delays or failures in these trials could significantly impact the company's timeline and ability to obtain regulatory approvals.

Additionally, Annovis is subject to the risks inherent in the biopharmaceutical industry, including competition from other therapies, the ability to manufacture its product candidate at scale, and the potential for adverse events or safety concerns. The company's limited operating history and history of net losses also pose risks to its long-term viability.

Outlook

Annovis recently reported positive interim analysis results for both its Phase 3 PD study and Phase 2/3 AD study, which allowed the company to proceed with the studies as planned. The company expects to report topline results from the Phase 3 PD study in June 2024 and has already reported data from the Phase 2/3 AD study in April 2024.

Following the completion of these studies, Annovis plans to discuss the AD data with the FDA and move forward with a next Phase 3 study to confirm and expand the findings in an 18-month disease-modifying trial, focusing on biomarker-positive early AD patients. The company's goal is to have conducted the required pivotal studies for Buntanetap to be able to file two new drug applications (NDAs) with the FDA by the end of 2026.

Conclusion

Annovis Bio is a clinical-stage company developing a potentially disease-modifying therapy for Alzheimer's and Parkinson's diseases. The company's lead product candidate, Buntanetap, has shown promising results in early clinical trials, demonstrating improvements in biomarkers, cognition, and function in AD and PD patients.

With ongoing Phase 3 studies in early PD and mild to moderate AD patients, Annovis is well-positioned to potentially bring a much-needed disease-modifying treatment to market for these devastating neurodegenerative disorders. However, the company faces significant risks and uncertainties, and will need to raise substantial additional capital to complete the development and commercialization of Buntanetap. Investors should closely monitor the company's progress and upcoming data readouts as it continues to advance its pipeline.
