$712.9 million in cash, cash equivalents and investments provide runway through 2025

SOUTH SAN FRANCISCO, Calif., Feb. 28, 2023 (GLOBE NEWSWIRE) -- Alector, Inc. (Nasdaq: ALEC), a clinical-stage biotechnology company pioneering immuno-neurology, today reported fourth quarter and full year 2022 financial results and recent portfolio and business updates. As of December 31, 2022, Alector’s cash, cash equivalents and investments totaled $712.9 million.

“2022 was marked by significant momentum and focus on our programs and prioritization across our pipeline as we continued to cement our position as an innovator in advancing immuno-neurology,” said Arnon Rosenthal, Ph.D., Chief Executive Officer of Alector. “We shared positive data from our INFRONT-2 Phase 2 trial of latozinemab in patients with symptomatic FTD-C9orf72 and advanced our INVOKE-2 Phase 2 Alzheimer’s disease study with AL002, the most advanced TREM2 candidate in clinical development. We are encouraged by recent progress in the Alzheimer’s disease space and believe our first-in-class drug candidates that harness the power of microglia, the brain’s immune cells, have the potential to improve neurodegeneration outcomes either as stand-alone therapies or potentially in combination with anti-beta amyloid drugs.” 

Sara Kenkare-Mitra, Ph.D., President and Head of Research and Development at Alector added, “Last year was transformational for Alector as we continued to strengthen our world-class and seasoned leadership team and bolster key talent across the organization. Looking ahead, we believe we are well-positioned both financially and organizationally to execute on our strategic priorities in 2023 and beyond.”

Pipeline Prioritization and Cash Runway Extension Through 2025

Alector plans to prioritize its late-stage immuno-neurology programs, including its progranulin and TREM2 product candidates, to extend cash runway through 2025.

Recent Clinical Updates and 2023 Milestones

Immuno-Neurology Portfolio
Progranulin Programs (Latozinemab, AL101) Being Developed in Collaboration with GSK

  • Enrollment is ongoing globally in the INFRONT-3 randomized, placebo-controlled, pivotal Phase 3 clinical trial evaluating the efficacy and safety of latozinemab (AL001) in at-risk and symptomatic patients with frontotemporal dementia due to a progranulin gene mutation (FTD-GRN). In June 2022, the first patient from the trial was enrolled and dosed in the optional open-label extension (OLE) study, and enrollment in the OLE is ongoing. Alector is preparing to engage with regulatory authorities in mid-2023. The purpose of the meeting is to discuss statistical analysis plans based on emerging knowledge in the field that may enable Alector to complete the INFRONT-3 study with fewer patients and/or a shorter treatment duration. The company is targeting an INFRONT-3 data readout in early 2025 pending regulatory feedback.  
  • In November 2022 at the 15th Clinical Trials on Alzheimer's Disease (CTAD) conference, Alector presented positive data from the multiple-dose cohorts of the first-in-human Phase 1 study of AL101 in healthy volunteers.
    • Results demonstrated that AL101 was well tolerated and increased progranulin levels in plasma and CSF in a dose-dependent manner.
    • The pharmacokinetic (PK) and pharmacodynamic (PD) profile of AL101 supports future development in larger indications such as Alzheimer’s disease (AD) and Parkinson’s disease (PD).
    • Alector and GSK plan to advance the AL101 program in 2023, with the initiation of an Asian PK bridging study to be followed by a global Phase 2 clinical trial in early AD.
  • In March 2022 at the AD/PD 2022 International Conference on Alzheimer’s and Parkinson’s Diseases and related neurological disorders, Alector presented positive 12-month data from the INFRONT-2 Phase 2 clinical trial of latozinemab in FTD patients with a C9orf72 genetic mutation (FTD-C9orf72). These data build upon the previously disclosed study results in FTD-GRN patients and support the company’s efforts to expand the progranulin franchise into additional neurodegenerative disease indications.
    • Clinical outcome assessments using the CDR® plus NACC FTLD-SB scale found that treatment of FTD-C9orf72 patients with latozinemab resulted in a trend toward a delay of approximately 54% in annualized disease progression compared to a matched control cohort from the ALLFTD consortium.
    • Mean levels of glial fibrillary acidic protein (GFAP), a biomarker of astrogliosis that is an indicator of disease and/or injury to the central nervous system, decreased over 12 months in both plasma and cerebrospinal fluid (CSF) in latozinemab-treated FTD-C9orf72 patients.
    • Latozinemab was generally well tolerated when administered monthly for a year or more, consistent with other study cohorts.
    • The company expects to report additional data from the INFRONT-2 trial of latozinemab in FTD-C9orf72 patients during the second half of 2023.

TREM2 Program (AL002) Being Developed in Collaboration with AbbVie

  • In January 2023, the first patient was enrolled and dosed in a long-term extension (LTE) of the INVOKE-2 Phase 2 clinical trial for which Alector will receive a $17.8 million milestone payment from AbbVie. Alector plans to complete INVOKE-2 trial enrollment in the third quarter of 2023, with top-line data expected by the fourth quarter of 2024. The INVOKE-2 trial is designed to evaluate the efficacy and safety of AL002 in slowing disease progression in individuals with early AD.
  • AbbVie has an exclusive option to globally develop and commercialize AL002. AbbVie’s exercise of that option would prompt a $250 million payment to Alector.
  • AL002 targets Triggering Receptor Expressed on Myeloid cells 2 (TREM2) to increase TREM2 signaling and the functionality of microglia.

MS4A Program (AL044)

  • In September 2022, Alector commenced its first-in-human Phase 1 trial of AL044, with the intention of developing that candidate in Alzheimer’s disease and potential orphan indications. Based on initial PK and tolerability data, the company decided to close the trial. Alector is actively pursuing a back-up MS4A program to develop an IND-ready candidate with a potentially improved dosing and tolerability profile.

Recent Corporate Updates

  • In 2022, Alector expanded its management team with the appointments of Marc Grasso, M.D., as Chief Financial Officer in February, Gary Romano, M.D., Ph.D., as Chief Medical Officer in May and Peter Heutink, Ph.D., as Chief Scientific Officer in October.
  • Last year the U.S. Patent and Trademark Office issued patents covering the latozinemab composition of matter and the use of AL101 for treating AD, PD and other neurodegenerative diseases including FTD. 

Fourth Quarter and Full Year 2022 Financial Results

Revenue. Collaboration revenue for the quarter ended December 31, 2022, was $14.4 million, compared to $14.0 million for the same period in 2021. Collaboration revenue for the year ended December 31, 2022, was $133.6 million, compared to $207.1 million for the same period in 2021. The decrease in year-over-year collaborative revenue was primarily due to $173.4 million collaboration revenue recognized from AL001 FTD-GRN license provided as part of the GSK Agreement in 2021, offset by revenue recognized in 2022 for GSK and AbbVie programs, including revenue recognized from the termination of the AL003 program.
