Alector Reports Third Quarter 2021 Financial Results

Initiated Phase 2 Clinical Trial of AL001 for the Treatment of Amyotrophic Lateral Sclerosis

Executed a Global Collaboration with GSK to Co-development and Co-commercialize Alector’s Progranulin Franchise Molecules for the Treatment of a Range of Neurodegenerative Diseases

SOUTH SAN FRANCISCO, Calif., Nov. 04, 2021 (GLOBE NEWSWIRE) -- Alector, Inc. (Nasdaq: ALEC), a clinical-stage biotechnology company pioneering immuno-neurology, today reported third quarter 2021 financial results and summarized recent portfolio and business updates. As of September 30, 2021, Alector’s cash, cash equivalents and investments totaled $777.9 million.

“During the third quarter, Alector reached a significant inflection point, validating our immuno-neurology approach and advancing our lead programs as we strive to help patients with neurodegenerative diseases,” said Arnon Rosenthal, Ph.D., co-founder and Chief Executive Officer of Alector. “We reported 12-month Phase 2 data for our lead therapeutic candidate, AL001, in which progranulin levels in frontotemporal dementia patients reverted to normal, and for the first time, showed encouraging early evidence of a slowing of disease progression across diverse datapoints. The signing of a collaborative agreement with GSK will further enable us to develop our progranulin franchise programs to their full potential in frontotemporal dementia, amyotrophic lateral sclerosis, Parkinson’s disease and Alzheimer’s disease. These achievements, alongside steady progress across our portfolio, are moving us ever closer to realizing our mission of harnessing the innate immune system to halt the destruction of neurodegenerative diseases.”

Clinical Updates

Progranulin Franchise

• In September, Alector initiated a Phase 2 clinical trial of AL001 in amyotrophic lateral sclerosis (ALS) patients with a C9orf72 genetic mutation. The six-month, randomized, double-blind, placebo-controlled, multicenter study is expected to enroll approximately 45 adult participants with C9orf72-associated ALS. The primary endpoint of the study is safety, tolerability, pharmacokinetics and pharmacodynamics of AL001, including plasma and cerebrospinal fluid (CSF) progranulin levels. The Phase 2 will also gather data on changes to multiple liquid biomarkers. ALS is the first of several indications beyond frontotemporal dementia where elevating progranulin levels is thought to have potential neuroprotective benefits.
  
  
• AL001 received orphan drug designation from the European Commission for the treatment of frontotemporal dementia. Orphan drug designation in the EU may be granted for medicines in development for debilitating or life-threatening conditions that affect fewer than five in 10,000 people in the EU and provides benefits to the sponsor such as protocol assistance, reduced regulatory fees and extended market exclusivity. AL001 has previously received Fast Track and Orphan Drug designations from the U.S. Food and Drug Administration.
  
  
• Twelve-month data from the open-label INFRONT-2 Phase 2 clinical trial of AL001 in patients with frontotemporal dementia with a progranulin mutation (FTD-GRN) were presented at the Alzheimer’s Association International Conference (AAIC) held in July 2021. AL001 showed a favorable safety profile, successful elevation of progranulin levels and encouraging evidence that treatment may slow disease progression.⁽¹⁾
  
  
• In July, Alector and GlaxoSmithKline (GSK) entered into a global collaboration to co-develop and co-commercialize AL001 and AL101 for the treatment of neurodegenerative diseases, including FTD-GRN, as well as other forms of FTD, ALS, Alzheimer’s disease and Parkinson’s disease. Under the terms of the agreement, Alector will receive $700 million in upfront payments, $500 million of which was received in August 2021 with a second payment to occur in the first quarter of 2022.

Alzheimer’s Disease Portfolio

• Two posters were presented at the 2021 AAIC for Alector’s AL002 program providing data from a Phase 1 study in healthy volunteers and details on the design of the ongoing INVOKE-2 Phase 2 clinical trial. AL002 is Alector’s first-in-class monoclonal antibody that binds to the TREM2 receptor to optimize microglial activity in the brain. Alector is developing AL002 as a potential treatment for Alzheimer’s disease in collaboration with AbbVie.
  

Corporate News

• Sam Jackson, M.D., MBA, and Linda Rubinstein joined Alector’s executive leadership team assuming the roles of interim Chief Medical Officer and interim Chief Financial Officer, respectively.
  • Dr. Jackson joined Alector in 2020 as Senior Vice President, Clinical Sciences overseeing Alector’s clinical science and clinical operations functions.
  • Ms. Rubinstein brings significant industry and financial experience to Alector, having served as Chief Financial Officer or interim Chief Financial Officer to numerous biotechnology companies.
• Elizabeth Garofalo, M.D., a veteran biopharmaceutical executive with more than 25 years of experience in global clinical development and regulatory affairs with a focus on neurology, was appointed to Alector’s Board of Directors.

Third Quarter 2021 Financial Results

Revenue. Collaboration revenue for the quarter ended September 30, 2021, was $182.4 million, compared to $5.9 million for the same period in 2020. In August, Alector received $500 million as part of the collaboration agreement with GSK. The increase in 2021 third quarter revenue was mainly due to the recognition of $179.8 million of the upfront payment from GSK.

R&D Expenses. Total research and development expenses for the quarter ended September 30, 2021, were $43.1 million, compared to $43.8 million for the quarter ended September 30, 2020. The decrease in R&D expenses was attributable to timing of manufacturing of drug supply and clinical trials start-up costs.

G&A Expenses. Total general and administrative expenses for the quarter ended September 30, 2021, were $13.0 million, compared to $15.8 million for the same period in 2020. This decrease was primarily due to reduced legal fees.

Net Income (Loss). For the quarter ended September 30, 2021, Alector reported a net income of $126.6 million, or $1.56 net income per share, compared to a net loss of $52.7 million, or $0.67 net loss per share, for the same period in 2020.

Cash Position. Cash, cash equivalents, and marketable securities were $777.9 million as of September 30, 2021.

About Alector
Alector is a clinical-stage biotechnology company pioneering immuno-neurology, a novel therapeutic approach for the treatment of neurodegenerative diseases. Immuno-neurology targets immune dysfunction as a root cause of multiple pathologies that are drivers of degenerative brain disorders. Alector has discovered and is developing a broad portfolio of innate immune system programs, designed to functionally repair genetic mutations that cause dysfunction of the brain’s immune system and enable the rejuvenated immune cells to counteract emerging brain pathologies. Alector’s immuno-neurology product candidates are supported by biomarkers and target genetically defined patient populations in frontotemporal dementia and Alzheimer’s disease. This scientific approach is also the basis for the company’s immuno-oncology programs. Alector is headquartered in South San Francisco, California.
