Recent Business Highlights

Progranulin Portfolio: AL001, AL101

• In December 2019, the U.S. Food and Drug Administration (FDA) granted Fast Track Designation for AL001 for the treatment of FTD-GRN patients.
  
  
• In December 2019, Alector reported Phase 1b results of AL001 in symptomatic FTD-GRN patients. In the trial, AL001 met all primary and secondary endpoints. Treatments with AL001 also showed a statistically significant normalization in a number of disease-associated proteins and an initial trend of decreasing levels of plasma Neurofilament (NfL) in patients compared to baseline.
   
• Alector initiated an open-label Phase 2 trial investigating the use of AL001 in patients with FTD-GRN and FTD-C9orf72 in September 2019. The company plans to present data from the ongoing Phase 2 study of AL001 patients at a conference later this year and advance AL001 into a pivotal Phase 3 study in 2020.
   
• In January 2020, Alector initiated a Phase 1 study of AL101 in healthy volunteers.
  
  
• In February 2020, the FDA granted AL101 Fast Track Designation for the treatment of patients with FTD-GRN.

Alzheimer’s Disease Portfolio: AL002, AL003, AL014

• In December 2019, Alector reported results from the single ascending dose phase of the Phase 1 study of AL002 in healthy volunteers at the 12th Clinical Trials on Alzheimer’s Disease (CTAD) Meeting. AL002 achieved all primary and secondary endpoints, including safety. AL002 was generally well-tolerated and reduced CSF soluble TREM2 (sTREM2) in a dose-dependent manner. AL002 is being developed by Alector in collaboration with its partner AbbVie.
  
  
• In December 2019, Alector designated AL014 as its third prioritized product candidate in Alzheimer’s disease. AL014 targets MS4A4A, a transmembrane receptor protein that is expressed selectively in microglia in the brain and is associated with control of microglia functionality and/or viability. Alector plans to initiate Phase 1 development for AL014 within the next 12-15 months.
  
  
• In January 2020, Alector announced the dosing of the first Alzheimer’s disease patient in the Phase 1b portion of the clinical study of AL003. AL003 is being developed in collaboration with its partner, AbbVie.

Fourth Quarter and Full Year 2019 Financial Results

Revenue. Collaboration revenue for the quarter ended December 31, 2019, was $6.0 million compared to $9.1 million for the same period in 2018. Collaboration revenue for the year ended December 31, 2019, was $21.2 million compared to $27.5 million for the same period in 2018. This decrease was primarily due to an increase in total expected costs for the AL002 and AL003 programs through the completion of proof-of concept.

R&D Expenses. Total research and development expenses for the quarter ended December 31, 2019, were $25.8 million compared to $24.1 million for the same period in 2018. Total research and development expenses for the year ended December 31, 2019, were $100.5 million compared to $73.0 million for the same period in 2018. This increase was driven by an increase in personnel-related expenses as headcount grew to support the advancement of the clinical and preclinical programs. There was an increase in facilities and other unallocated research and development related to the lease expense for the new headquarters and higher depreciation expense. Expenses for AL101 increased as well as for other early stage programs as investment in research and clinical pipeline continues. 

G&A Expenses. Total general and administrative expenses for the quarter ended December 31, 2019 were $12.6 million compared to $4.1 million for the same period in 2018. Total general and administrative expenses for the year ended December 31, 2019 were $35.1 million compared to $11.9 million for the same period in 2018. This increase was primarily due to an increase in personnel-related expenses due to increased headcount. Facilities and general overhead expenses increased due to additional lease expense related to the lease for the new headquarters, higher depreciation expense, directors and officers’ insurance, and additional legal, information technology, and human resources costs to operate as a public company.

Net Loss. For the quarter ended December 31, 2019, Alector reported a net loss of $30.5 million, compared to a net loss of $17.4 million for the same period in 2018.
