REDWOOD CITY, Calif., Nov. 09, 2020 (GLOBE NEWSWIRE) — Allakos Inc. (the “Company”) (Nasdaq: ALLK), a biotechnology company developing lirentelimab (AK002) for the treatment of eosinophil and mast cell-related diseases, today reported financial results for the third quarter ended September 30, 2020 and provided an update of its ongoing development activities.

Business Updates

• Announced positive results from our prospective prevalence study showing that 45% (181/405) of symptomatic patients biopsied with chronic unexplained gastrointestinal (GI) symptoms or functional gastrointestinal disorders (FGIDs) such as irritable bowel syndrome (IBS) and functional dyspepsia (FD) met the histologic criteria for eosinophilic gastritis (EG) and/or eosinophilic duodenitis (EoD). The results suggest that EG and/or EoD are significantly underdiagnosed among these patients. Since many people in the United States and worldwide suffer from chronic unexplained gastrointestinal symptoms or FGIDs, the results from this study suggest that EG and/or EoD may be more common than previously documented in the literature.
• Announced positive safety, pharmacokinetic, and pharmacodynamic results from a randomized, double-blind, placebo-controlled Phase 1 study of subcutaneous lirentelimab in healthy volunteers. The results showed that subcutaneously administered lirentelimab had bioavailibity of 63% and suppressed eosinophils for up to 85 days. Subcutaneously administered lirentelimab was well tolerated with no serious adverse events, no injection site reactions, and no injection reactions/infusion-related reactions.
• Announced the publication of the positive results from the Phase 2 study of lirentelimab in patients with EG and/or EoD (ENIGMA) in the
  
  New England Journal of Medicine
  
  
  .
  
• Closed an underwritten public offering in November 2020, issuing 3,506,098 shares of common stock at an offering price of $82.00 per share. Aggregate net proceeds received from the offering were approximately $271.7 million, after deducting underwriting discounts and commissions.
• The randomized, double-blind, placebo-controlled Phase 3 study of lirentelimab in patients with EG and/or EoD is ongoing with topline data expected in the second half of 2021.
• The randomized, double-blind, placebo-controlled Phase 2/3 study of lirentelimab in patients with eosinophilic esophagitis (EoE) is ongoing with topline data expected in the second half of 2021.

About Allakos

Allakos is a clinical stage biotechnology company developing antibodies that target immunomodulatory receptors present on immune effector cells involved in allergic, inflammatory, and proliferative diseases. The Company’s lead antibody, lirentelimab (AK002), is being evaluated in a Phase 3 study in eosinophilic gastritis (EG) and/or eosinophilic duodenitis (EoD) and a Phase 2/3 study in eosinophilic esophagitis (EoE). Lirentelimab targets Siglec-8, an inhibitory receptor selectively expressed on human mast cells and eosinophils. Inappropriately activated eosinophils and mast cells have been identified as key drivers in a number of severe diseases affecting the gastrointestinal tract, eyes, skin, lungs and other organs. Lirentelimab has been tested in multiple clinical studies. In these studies, lirentelimab eliminated blood and tissue eosinophils, inhibited mast cells and improved disease symptoms in patients with EG and/or EoD, EoE, mast cell gastrointestinal disease, severe allergic conjunctivitis, chronic urticaria and indolent systemic mastocytosis. For more information, please visit the Company’s website at
