SOUTH SAN FRANCISCO, Calif., Aug. 03, 2023 (GLOBE NEWSWIRE) -- Alector, Inc. (NASDAQ:ALEC), a clinical-stage biotechnology company pioneering immuno-neurology, today reported second quarter 2023 financial results and recent portfolio and business updates. As of June 30, 2023, Alector's cash, cash equivalents and investments totaled $630.0 million.

"We expect to complete enrollment in the INVOKE-2 Phase 2 clinical trial of AL002 in early Alzheimer's disease in the third quarter," said Arnon Rosenthal, Ph.D., Chief Executive Officer of Alector. "We have received positive feedback from the FDA and the EMA to conduct a primary analysis on approximately 90-100 symptomatic participants in our pivotal INFRONT-3 Phase 3 clinical trial of latozinemab in FTD-GRN. We anticipate completing enrollment in INFRONT-3 in the fourth quarter of this year."

Sara Kenkare-Mitra, Ph.D., President and Head of Research and Development at Alector added, "While we continue to progress our late-stage clinical programs, we are also strategically advancing our innovative research portfolio to fuel our pipeline. I am particularly excited about the ongoing development of our blood brain barrier technology and the progress on our preclinical program targeting GPNMB for the treatment of Parkinson's disease."

Recent Clinical Updates

Immuno-Neurology Portfolio

TREM2 Program (AL002) Being Developed in Collaboration with AbbVie

• Alector closed screening and plans to complete enrollment in the INVOKE-2 clinical trial in the third quarter of 2023, with data expected in the fourth quarter of 2024. The INVOKE-2 Phase 2 trial is designed to evaluate the efficacy and safety of AL002 in slowing disease progression in individuals with early Alzheimer's disease (AD).

• Alector presented an update on INVOKE-2 at the Alzheimer's Association International Conference (AAIC) in July 2023. The presentation highlighted that treatment-emergent MRI findings resembling amyloid-related imaging abnormalities (ARIA) in INVOKE-2 are similar to the ARIA reported following treatment with anti-amyloid beta antibodies.
  • Alector previously presented results from a Phase 1 trial of AL002 in healthy volunteers, which demonstrated both dose-dependent target engagement and activation of microglia.
  • Microglial activation is hypothesized to not only enhance clearance of misfolded proteins that accumulate and form amyloid plaques but also perform other supportive microglia functions, including maintenance of neuronal and synaptic health.

• At AAIC, the company also presented a poster on mouse model data demonstrating that TREM2 activation improved AD biomarkers, including amyloid and tau.

Progranulin Programs (latozinemab (AL001) and AL101/ GSK4527226) Being Developed in Collaboration with GSK

• Alector and GSK held a Type C meeting with the U.S. Food and Drug Administration (FDA) and received scientific advice from the European Medicines Agency (EMA) regarding the pivotal INFRONT-3 Phase 3 clinical trial of latozinemab in participants with frontotemporal dementia due to progranulin gene mutation (FTD-GRN).
  • Alector and GSK aligned with the FDA and EMA to conduct the primary analysis on symptomatic participants in INFRONT-3. Based on feedback from the regulatory agencies, the companies performed a sample size re-estimation that is anticipated to support a more focused enrollment of approximately 90-100 symptomatic participants for a treatment duration of 96 weeks.
  • Alector plans to complete enrollment in INFRONT-3 in the fourth quarter of 2023.

• In a recent data cut from the FTD-C9orf72 cohort of the open label INFRONT-2 Phase 2 clinical trial of latozinemab, Alector confirmed a two- to threefold elevation in progranulin levels in CSF and plasma. The company conducted an analysis of disease progression rates for the 14 participants who were treated with latozinemab compared with baseline-matched controls from the ALLFTD registry. The small sample size and a high degree of variability in disease progression in both groups rendered the results uninformative regarding treatment effect.

• In June 2023, Alector published a manuscript in the Journal of Translational Medicine titled "Latozinemab, a novel progranulin-elevating therapy for frontotemporal dementia." This publication details Alector's development of latozinemab and highlights findings demonstrating that the sortilin receptor is a viable target for PGRN-elevating therapy, particularly in patients who have a PGRN deficiency leading to FTD.

• Alector and GSK plan to initiate a global Phase 2 clinical trial with AL101/GSK4527226 in early AD. The companies also plan to present a poster on the pharmacokinetic and pharmacodynamic modeling of PGRN elevation in blood and CSF based on a Phase 1 trial of AL101 at the American College of Clinical Pharmacology (ACCP) being held in Bellevue, Washington from September 10-12, 2023.

Early Research Pipeline

• Alector is developing its proprietary, versatile blood brain barrier technology to selectively support its next-generation product candidates. 

• The company is developing an investigational therapy, ADP027, which modulates GPNMB for the treatment of Parkinson's disease.

Recent Corporate Updates

• In the second quarter of 2023, the U.S. Patent and Trademark Office issued patents covering methods of treatment using AL002. The European Patent Office also issued a patent in the second quarter of 2023 covering AL002 compositions and methods of use.

Second Quarter 2023 Financial Results

Revenue. Collaboration revenue for the quarter ended June 30, 2023, was $56.2 million, compared to $79.9 million for the same period in 2022. The $23.6 million decrease was mainly due to $68.9 million of collaboration revenue recognized in the second quarter of 2022 due to changes in estimated costs to satisfy the performance obligations resulting from the termination of the AL003 program and a $16.7 million decrease in revenue recognized for the latozinemab programs. This was offset by a $33.5 million increase in revenue recognized for the AL101 programs, including a cumulative non-cash revenue adjustment due to contract modification to have GSK operationalize the AL101 Phase 2 trial, and a $28.5 million increase to collaboration revenue for the AL002 program due to changes in total expected costs and the addition of AL002 LTE and patient replacement revenue in 2023.

R&D Expenses. Total research and development expenses for the quarter ended June 30, 2023, were $46.2 million, compared to $54.5 million for the quarter ended June 30, 2022. The decrease of $8.4 million was mainly due to the Company's strategy to prioritize late-stage programs and higher cost share amounts with GSK that are recorded as contra expense.

G&A Expenses. Total general and administrative expenses for the quarter ended June 30, 2023, were $13.6 million, compared to $15.8 million for the same period in 2022. The decrease of $2.2 million was primarily due to a decrease in consulting expenses related to accounting, recruiting, IT, and other general expenses.

Net Income. For the quarter ended June 30, 2023, Alector reported a net income of $1.4 million, or $0.02 net income per share, compared to a net income of $9.9 million, or $0.12 net income per share, for the same period in 2022.

Cash Position. Cash, cash equivalents, and investments were $630.0 million as of June 30, 2023. Management continues to expect that this will be sufficient to fund current operations through 2025.

2023 Guidance. Management is revising guidance for the year ending 2023, increasing collaboration revenue to now be between $90 million and $100 million, decreasing total research and development expenses to now be between $210 million and $220 million and tightening expectations for total general and administrative expenses to now be between $60 million and $65 million.
