Additional data from the INFRONT-2 Phase 2 clinical trial of latozinemab in FTD-C9orf72 expected during the second half of 2023
Company and GSK plan to advance AL101 program in 2023, with the initiation of a PK bridging study to be followed by a global Phase 2 clinical trial in early Alzheimer’s disease
“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
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
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.
November 2022at 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.
March 2022at the AD/PD™ 2022 International Conferenceon 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
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 millionmilestone 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 millionpayment to Alector.
- AL002 targets Triggering Receptor Expressed on Myeloid cells 2 (TREM2) to increase TREM2 signaling and the functionality of microglia.
MS4A Program (AL044)
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.

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 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.
