AUSTIN, Texas, May 06, 2020 (GLOBE NEWSWIRE) -- Cassava Sciences, Inc. SAVA, a clinical-stage biotechnology company focused on Alzheimer's disease, today announced recent business highlights and financial results for the first quarter ended March 31, 2020. Net loss was $1.2 million, or $0.05 per share, compared to a net loss of $1.4 million, or $0.08 per share, for the same period in 2019. Net cash used in operations was $1.2 million during the first quarter of 2020. Net cash use in full-year 2020 is expected to be approximately $5 million. Cash and cash equivalents were $25.6 million as of March 31, 2020, with no debt.

"Cassava Sciences had a productive quarter with its research programs in Alzheimer's disease," said Remi Barbier, President & CEO. "As a result, we anticipate having top-line results for our Phase 2b study of PTI-125, our lead drug candidate for Alzheimer's, earlier than mid-2020."

Phase 2b Study – Early data readout on effects of PTI-125 on tau protein anticipated
In March 2020, Cassava Sciences announced the completion of a double-blind, randomized, placebo-controlled study of PTI-125 in 64 patients with mild-to-moderate Alzheimer's disease, 50-85 years of age, with 16 ≤ MMSE ≤ 26. Study participants received PTI-125 100 mg, 50 mg or matching placebo, twice-daily, for 28 continuous days.  The primary efficacy endpoint is the effect of PTI-125 vs placebo on CSF levels of tau protein, and other biomarker assessments.

Open-label Study – Initiated in March, approximately 20% enrolled
In March 2020, Cassava Sciences announced the initiation of an open-label, multi-center study of PTI-125 at 100 mg twice-daily for 12 months. Every study participant receives drug treatment in an open-label design. This on-going study has a target enrollment of approximately 100 patients with mild-to-moderate Alzheimer's disease. The study is approximately 20% enrolled.

Finance Update – $2.9 million of new NIH research grant awards announced in 2020
Cassava Sciences' scientific programs continue to be supported by research grant awards from the National Institutes of Health (NIH), the nation's foremost medical research agency. In April 2020, the Company announced it had been awarded a new $2,500,000 research grant from NIH. In March 2020, NIH awarded the Company supplemental research funding in the amount of $374,000. The NIH's National Institute on Aging awarded the Company these research grant award following an in-depth, peer review of PTI-125. Peer review, one of the gold standards of science, is a process where independent, outside scientists evaluate the merits of new research.

Operations Update – No major disruptions to date
In these times of pandemic, Cassava Sciences' top priorities are to protect the health, well-being, and safety of its employees and partners, while still focusing on the key drivers of its business. The company believes it remains on-track to achieve its major strategic objectives for 2020. The Company has not experienced major disruptions across its drug manufacturing operations or supply of materials. Its broad spectrum of technical consultants, scientific advisors and service providers continue to provide timely services. The Company has adapted flexible business practices, such as remote work arrangements and temporary travel restrictions, to insure it continues to operate safety and cautiously while meeting its public health responsibilities.

Cassava Sciences recognizes the on-going pandemic has created an unstable and uncertain situation in the national economy. The Company continues to closely monitor the latest information to make timely, informed business decisions and public disclosures regarding the potential impact of pandemic on its operations. However, the scope of this pandemic is unprecedented and its long-term impact on the Company's operations and financial condition cannot be reasonably estimated at this time.

Financial Highlights for First Quarter 2020

• At March 31, 2020, cash and cash equivalents were $25.6 million, compared to $23.1 million at December 31, 2019, with no debt.

• Cash balance included $3.6 million in proceeds from exercise of warrants in the first quarter of 2020. Approximately 1.6 million warrants remain outstanding, each with an exercise price of $1.25 per share. All warrants expire February 2021.

• Net cash used in operations during the quarter ended March 31, 2020 was $1.2 million, net of reimbursements received from NIH grant awards.
   
• Net cash use for full year 2020 is expected to be approximately $5.0 million, consistent with previous financial guidance.

• Research grant funding reimbursements of $1.3 million were received from NIH and recorded as a reduction in research and development (R&D) expenses. This compared to $0.8 million of NIH grant receipts received for the same period in 2019.

• R&D expenses were $0.5 million. This compared to $0.6 million for the same period in 2019, representing a 5% decrease. While Phase 2 clinical program expenses were higher in Q1 2020, overall expense was reduced by greater NIH reimbursement.

• General and administrative (G&A) expenses were $0.8 million. This compared to $0.9 million for the same period in 2019, representing a 11% decrease. The decrease was due primarily to lower stock-based compensation expense compared to 2019.

About PTI-125
Cassava Sciences' lead therapeutic product candidate is for the treatment of Alzheimer's disease.  PTI-125 is a proprietary, small molecule (oral) drug that restores the normal shape and function of altered filamin A (FLNA), a scaffolding protein, in the brain. Altered FLNA in the brain disrupts the normal function of neurons, leading to Alzheimer's pathology, neurodegeneration and neuroinflammation. The underlying science is published in peer-reviewed scientific journals, including Journal of Neuroscience, Neurobiology of Aging, Journal of Biological Chemistry and Journal of Prevention of Alzheimer's Disease. The Company is also developing an investigational diagnostic, called SavaDx, to detect Alzheimer's disease with a simple blood test.

About Alzheimer's Disease
Alzheimer's disease is a progressive brain disorder that destroys memory and thinking skills. Currently, there are no drug therapies to halt Alzheimer's disease, much less reverse its course. In the U.S. alone, approximately 5.8 million people are currently living with Alzheimer's disease, and approximately 487,000 people age 65 or older developed Alzheimer's in 2019.¹ The number of people living with Alzheimer's disease is expected to grow dramatically in the years ahead, resulting in a growing social and economic burden.²
