Commentary on the Quarter:

"In the third quarter, we expanded our first-in-class clinical immuno-neurology pipeline with AL044, a biologic targeting MS4A, a brain immune checkpoint molecule and a genetic risk factor for Alzheimer’s disease. We also continued to advance our INFRONT-3 Phase 3 pivotal study of latozinemab for frontotemporal dementia with progranulin mutations, or FTD-GRN, and our INVOKE-2 Phase 2 Alzheimer’s disease study with AL002, which activates TREM2 receptor signaling," said Arnon Rosenthal, Ph.D., Chief Executive Officer of Alector. "We will be reporting new data from the Phase 1 study of AL101 later this year at CTAD in addition to follow-up data from the INFRONT-2 Phase 2 trial in patients with symptomatic FTD-C9orf72 in 2023."

"We anticipate biomarker data from the AL044 healthy volunteer study and completion of enrollment in our INVOKE-2 study in 2023. We believe that our immuno-neurology drug candidates, which are designed to regulate key aspects of microglial proliferation, survival, migration, lysosomal function and immune response, could prove important in effectively treating neurodegeneration 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, "Our immuno-oncology pipeline continues to advance as well. We remain on track to submit an IND for AL009, Alector’s first-in-class multi-Siglec inhibitor, by the end of the year."

"We are also thrilled to have expanded our talented leadership team over the past quarter as we welcomed Peter Heutink, Ph.D., as Chief Scientific Officer," said Dr. Kenkare-Mitra. "Peter’s expertise in the human genetics of neurodegenerative disease is important to our efforts at Alector."

Immuno-Neurology Portfolio

Progranulin Assets (Latozinemab, AL101)

Enrollment is ongoing globally in the INFRONT-3 randomized, placebo-controlled, pivotal Phase 3 trial evaluating the efficacy and safety of latozinemab (AL001) in at-risk and symptomatic patients with FTD-GRN. The first patient has been enrolled in the open-label extension study.

The company expects to report follow-up data from the INFRONT-2 Phase 2 clinical trial of latozinemab in frontotemporal dementia patients with a C9orf72 genetic mutation (FTD-C9orf72) in 2023.

Alector will present a poster, Repeat IV and SC dosing of the Anti-Sortilin Antibody AL101, with data from the Phase 1 trial of AL101 in healthy volunteers at the 15th Clinical Trials on Alzheimer’s Disease (CTAD) conference, being held in San Francisco, California from November 29 to December 2, 2022. AL101 is intended to elevate progranulin levels in a manner similar to latozinemab, and the company plans to investigate AL101 for the treatment of Alzheimer’s disease (AD) and Parkinson’s disease (PD).

Latozinemab and AL101 are being developed in collaboration with GSK.

TREM2 Asset (AL002)

Enrollment in the INVOKE-2 Phase 2 study of AL002 continues. The INVOKE-2 Phase 2 clinical trial is designed to evaluate the efficacy and safety of AL002 in slowing disease progression in individuals with early AD. AL002 is being developed in collaboration with AbbVie and targets Triggering Receptor Expressed on Myeloid cells 2 (TREM2) to increase TREM2 signaling and the functionality of microglia, which are brain-specific immune cells.

Novel MS4A Asset (AL044)

The company commenced its first-in-human Phase 1 trial of AL044, the first clinical-stage drug candidate to target MS4A, a major genetic risk factor for AD and an immune checkpoint expressed on microglia. The study, initiated in September of this year, is investigating the safety profile, pharmacokinetics (PK), pharmacodynamics (PD) and target engagement of AL044 in healthy adults. Safety and biomarker data from this study are anticipated in 2023. The company views MS4A as a master inhibitory checkpoint for the brain’s immune system and believes its inhibition will activate microglia in a disease-selective manner to broadly counteract Alzheimer’s disease and potentially orphan neurodegenerative indications.

Immuno-Oncology Portfolio

Multi-Siglec and SIRPα Assets (AL009, AL008)
anticipates submitting an IND for its AL009 innate immuno-oncology program before the end of the year. The company will present a poster, Characterization of suppressive myeloid cells in solid tumors to refine disease selection in a Phase 1 study of the multi-Siglec inhibitor AL009, at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 37th Annual Meeting being held in Boston, Massachusetts and virtually from November 8 to 12, 2022. AL009 is a dual function biologic that inhibits multiple Siglec receptors on myeloid cells and simultaneously activates a stimulating receptor on the same cells. The company plans to prioritize tumor types that have immunosuppressive phenotypes and expects to study AL009 as a monotherapy and in combination with standard of care.

The company plans to utilize data and documentation from a regulatory filing previously submitted by Innovent to Chinese authorities for AL008 to support a potential IND submission in the U.S. AL008 is a novel innate immuno-oncology candidate with a dual mechanism of action, targeting SIRP-alpha (SIRPa) to inhibit the CD47- SIRPα pathway and activating Fc receptors to promote immuno-stimulatory pathways that drive anti-tumor immunity.

Recent Corporate Updates

Peter Heutink, Ph.D., began his role as Alector’s Chief Scientific Officer in October. Leveraging nearly 30 years of experience in the neurodegenerative disease space, Dr. Heutink provides scientific oversight of the company’s significant research pipeline and helps drive business strategy.

Third Quarter 2022 Financial Results

Revenue. Collaboration revenue for the quarter ended September 30, 2022, was $14.9 million, compared to $182.4 million for the same period in 2021. The decrease of $167.6 million was due to $173.4 million collaboration revenue recognized from AL001 FTD-GRN license provided as part of the GSK Agreement in 2021.

R&D Expenses. Total research and development expenses for the quarter ended September 30, 2022, were $48.3 million, compared to $43.1 million for the quarter ended September 30, 2021. The increase in R&D expenses was mainly driven by increased personnel-related expenses as well as an increase in AL002 expenses.

G&A Expenses. Total general and administrative expenses for the quarter ended September 30, 2022, were $14.3 million, compared to $13.0 million for the same period in 2021. The increase is primarily due to personnel-related expenses.

Net Income (Loss). For the quarter ended September 30, 2022, Alector reported net loss of $46.1 million, or $0.56 net loss per share, compared to a net income of $126.6 million, or $1.56 net income per share, for the same period in 2021.
