Commentary on the Quarter:

"We continue to make significant progress in building our pipeline of novel immuno-neurology and immuno-oncology drug candidates which engage the innate immune system to treat neurodegeneration and cancer," said Arnon Rosenthal, Ph.D., Chief Executive Officer of Alector.

"With the recent submission of an Investigational New Drug Application (IND) for our next first-in-class clinical drug candidate, AL044, Alector continues to build its position as an innovator in developing new approaches to tackle Alzheimer’s disease (AD) and other serious neurodegenerative disorders. The company is planning its first AL044 study in healthy volunteers. AL044 modulates MS4A, which is a genetic risk locus for AD and an immune checkpoint expressed on microglia cells. MS4A activity is associated with multiple AD pathologies, including: Abeta and Tau accumulation, earlier age of onset, and increased rate of cognitive decline. We believe that AL044 has significant potential to be effective in the treatment of AD."

"Patient enrollment is progressing in INVOKE-2, a Phase 2 study of AL002, which is our first-in-class anti-TREM2 antibody for early AD. Following a voluntary exclusion of APOE e4/e4 homozygous patients, we have not observed additional serious adverse events related to amyloid-related imaging abnormalities (ARIA). We are implementing earlier patient monitoring to the trial that is consistent with recently published guidelines for ARIA monitoring and management as we continue to prioritize patient safety. TREM2 is an important risk gene for AD and is believed to control the survival, function, proliferation, and migration of microglia, the brain’s immune cells."

"In addition to our robust AD portfolio, we are opening additional sites and expanding recruitment efforts to enroll our Phase 3 INFRONT-3 pivotal study of latozinemab for frontotemporal dementia (FTD) with progranulin mutations (FTD-GRN). Later this year, we also expect to share new data from the Phase 1 study of AL101, the second product candidate from the company’s progranulin portfolio."

Sara Kenkare-Mitra, Ph.D., President and Head of Research and Development at Alector, added, "We are pleased to announce that the company has completed IND enabling studies for our immuno-oncology program, AL009, and anticipates submitting an IND in 2022. AL009 is a first-in-class multi Siglec inhibitor that works to enhance both the innate and adaptive immune system response to tumors by blocking a critical glycan checkpoint pathway that drives immune inhibition. As a leader in targeting myeloid biology, this brings us closer to achieving our goal of building a portfolio of innate immuno-oncology therapies by utilizing the company’s expertise in the central and peripheral innate immune system."

"Alongside these encouraging clinical updates, Alector continues to attract world class talent and we are delighted to announce that Peter Heutink, Ph.D., will be joining us as Chief Scientific Officer. Peter brings considerable experience in human genetics of neurodegenerative diseases, functional genomics, and induced pluripotent stem cell (iPSC) technology that will help drive science and discovery at Alector."

Clinical Programs

Immuno-Neurology Portfolio
Progranulin Assets (Latozinemab, AL101)

Alector continues to progress the INFRONT-3 randomized, placebo-controlled, pivotal Phase 3 trial evaluating the efficacy and safety of latozinemab in at-risk and symptomatic patients with FTD-GRN. The company continues to build awareness of FTD, support genetic testing and educate the FTD patient community about the INFRONT-3 pivotal study to support clinical trial enrollment.

The company expects to report data at a medical conference later this year from the Phase 1 trial of AL101 in healthy volunteers. AL101 is being developed to elevate progranulin levels in a manner similar to latozinemab (AL001) with plans to investigate AL101 for the treatment of AD and Parkinson’s disease.
TREM2 and SIGLEC 3 Assets (AL002, AL003)

Enrollment in the INVOKE-2 Phase 2 study of AL002 continues with no additional serious adverse events related to ARIA following the exclusion of APOE e4/e4 homozygous patients. The company is implementing MRI monitoring prior to dose escalation for all clinical trial participants, consistent with recently published guidelines for ARIA monitoring and management. 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 brain specific immune cells.

As previously announced, AbbVie decided to terminate the CD33 collaboration program after Alector and AbbVie collaboratively reviewed next steps for AL003, which targets CD33. Both companies concluded the program did not warrant further development based on insufficient evidence of an effect on pharmacodynamic biomarkers from a Phase 1 study. This decision allows Alector to focus its resources on other more promising programs.
Novel MS4A Asset (AL044)

Alector has submitted a U.S. IND for AL044, which targets MS4A, a major genetic risk locus for AD and an immune checkpoint expressed on microglia immune system cells. Preclinical data suggest that AL044 may mimic or surpass the effects of a genetic variant of MS4A that is protective against AD.
Immuno-Oncology Portfolio
SIRPα and Multi-Siglec Assets (AL008, AL009)

The company intends to re-acquire the rights that were granted to Innovent Biologics for the development and commercialization of AL008. Innovent submitted an IND to the Chinese regulatory authorities, and Alector plans to utilize data and documentation from this regulatory filing to support a potential IND submission in the U.S. AL008 is a novel innate immuno-oncology candidate with a dual mechanism of action combining the inhibition of the CD47-SIRP-alpha (SIRPα) pathway with the activation of Fc receptors to promote immuno-stimulatory pathways that drive anti-tumor immunity.

The company has completed IND enabling studies for its first-in-class AL009 immuno-oncology program and anticipates submitting an IND later this year. 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.
Recent Corporate Updates

Dr. Peter Heutink, Ph.D., will join Alector as its soon-to-be new Chief Scientific Officer (CSO) in the fall of 2022. Dr. Heutink is a full professor, a group leader and the site speaker of the German Center for Neurodegenerative Diseases (DZNE) – Tübingen.

Second Quarter 2022 Financial Results

Revenue. Collaboration revenue for the quarter ended June 30, 2022, was $79.9 million, compared to $6.6 million for the same period in 2021. The increase of $73.3 million was due to a $52.0 million net increase to collaboration revenue under the AbbVie Agreement due to changes in estimated costs to satisfy the performance obligations resulting from the termination of the AL003 program, partially offset by increases in total expected costs for the AL002 program. The increase was also due to a $21.3 million increase in revenue recognized from the GSK Agreement.

R&D Expenses. Total research and development expenses for the quarter ended June 30, 2022, were $54.5 million, compared to $47.8 million for the quarter ended June 30, 2021. The increase in R&D expenses was mainly driven by increased personnel-related expenses, including stock-based compensation, as well as an increase in AL101 expenses.

G&A Expenses. Total general and administrative expenses for the quarter ended June 30, 2022, were $15.8 million, compared to $14.1 million for the same period in 2021. The increase was primarily due to an increase in personnel-related expenses, including stock-based compensation, offset by reduced legal expenses mainly to support the GSK collaboration deal in 2021.

Net Income (Loss). For the quarter ended June 30, 2022, Alector reported net income of $9.9 million, or $0.12 net income per share, compared to a net loss of $55.1 million, or $0.69 net loss per share, for the same period in 2021.

Cash Position. Cash, cash equivalents, and investments were $808.9 million as of June 30, 2022. Management anticipates that this will be sufficient to fund current operations into the second half of 2024.
