Exhibit 99.1
Allakos Announces Positive Results from its Ongoing Phase 1 Trial of AK006 in Healthy Volunteers, with AK006 Demonstrating High Receptor Occupancy on Mast Cells and a Favorable Safety Profile
– AK006 achieved serum concentrations consistent with levels demonstrating inhibitory activity in preclinical experiments –
– Skin biopsies from subjects treated with AK006 show high receptor occupancy –
– AK006 was well-tolerated with a favorable safety profile –
SAN CARLOS, Calif., June 25, 2024 (GLOBE NEWSWIRE) -- Allakos Inc. (Nasdaq: ALLK), a biotechnology company developing AK006 for the treatment of mast cell-driven diseases, today announced positive results from the single and multiple ascending Phase 1 study of intravenous (IV) AK006 in healthy volunteers. AK006 is a Siglec-6 monoclonal antibody that selectively inhibits mast cells. Inappropriate activation of mast cells has been identified as a pathogenic driver of multiple diseases, including chronic spontaneous urticaria, food allergy and asthma.
Phase 1 Study Results
Phase 1 AK006 Study in Healthy Volunteers and Patients with Chronic Spontaneous Urticaria
AK006 is being studied in an ongoing Phase 1 single IV and subcutaneous (SC) ascending dose (SAD) and multiple IV ascending dose (MAD) trial that includes a randomized, double-blind, placebo-controlled CSU arm (NCT06072157). The data announced today are from Parts A and B of the randomized, double-blind, placebo-controlled SAD and MAD IV cohorts of the study. In these cohorts, healthy volunteers were randomized 6:2 to receive doses of intravenous AK006 or placebo. AK006 was tested across five single ascending doses (5, 20, 80, 240 and 720 mg) and three MAD (80, 240 and 720 mg monthly) dose cohorts. The primary objective was to evaluate the safety and tolerability of single ascending doses and
multiple ascending IV doses of AK006 in healthy volunteers and to explore Siglec-6 receptor occupancy on mast cells in skin biopsy samples.
AK006 is also being studied in an ongoing randomized, double-blind, placebo-controlled cohorts of healthy volunteers receiving SC AK006 and also in a cohort of patients with CSU receiving IV AK006. In the CSU cohort, approximately 60 adult patients with antihistamine refractory CSU (including patients with prior biologics treatment), will be randomized 2:1 to receive 720 mg of IV AK006 or placebo once every four weeks (Q4W). The primary efficacy analysis will be the change in the urticaria activity score (UAS7) at week 14. Data from approximately 30 patients is expected at year end 2024.
About AK006
AK006 is a humanized IgG1 monoclonal antibody which activates the inhibitory receptor Siglec-6. Siglec-6 is found on the surface of mature mast cells and offers a way to selectively target mast cells. In preclinical experiments, AK006 inhibits IgE-dependent and IgE-independent mast cell activation including activation through IgE, MRGPRX2 and KIT receptors. In these experiments, AK006 drives deep mast cell inhibition and, in addition to its inhibitory activity, can reduce mast cell numbers via antibody-dependent cellular phagocytosis in the presence of activated macrophages.
About Allakos
Allakos is a clinical stage biotechnology company developing therapeutics that target immunomodulatory receptors present on immune effector cells involved in allergy, inflammatory and proliferative diseases. Activating these immunomodulatory receptors allows for the direct targeting of cells involved in disease pathogenesis and, in the setting of allergy and inflammation, has the potential to result in broad inhibition of inflammatory cells. The Company’s most advanced antibody in ongoing clinical development is AK006. AK006 targets Siglec-6, an inhibitory receptor expressed on mast cells. Mast cells are widely distributed in the body and play a central role in the inflammatory response. Inappropriately activated mast cells have been identified as key drivers in a number of severe diseases affecting the gastrointestinal tract, eyes, skin, lungs and other organs. In preclinical studies, AK006 appears to provide deep mast cell inhibition and, in addition to its inhibitory activity, reduce mast cell numbers.
