Apogee Therapeutics Announces First Participants Dosed in Phase 1 Clinical Trial of APG990, its Novel Half-Life Extended OX40L Antibody for the Treatment of Atopic Dermatitis and Other Inflammatory Diseases
Interim safety and pharmacokinetic data from Phase 1 healthy volunteers trial anticipated in 2025
Initiation of the first clinical trial of APG777 and APG990 combination expected to commence in 2025 with the potential for greater efficacy in atopic dermatitis and across I&I diseases
SAN FRANCISCO and WALTHAM, Mass., Aug. 19, 2024 (GLOBE NEWSWIRE) -- Apogee Therapeutics, Inc., (Nasdaq: APGE), a clinical-stage biotechnology company advancing novel biologics with potential for differentiated efficacy and dosing in the largest inflammatory and immunology (I&I) markets, including for the treatment of atopic dermatitis (AD), asthma, chronic obstructive pulmonary disease (COPD) and other I&I indications, today announced that it has initiated dosing of healthy volunteers in its first clinical trial for APG990, a novel, subcutaneous (SQ) half-life extended monoclonal antibody targeting OX40L, which is being developed initially as a treatment for people living with AD.
“The early initiation of the APG990 Phase 1 clinical trial marks another significant milestone for Apogee as we continue to focus on excellence in execution. We have advanced three of our programs into clinical trials in just 12 months, bringing potentially differentiated treatments closer to patients living with the largest I&I diseases,” said Michael Henderson, M.D., Chief Executive Officer of Apogee. “We are initially exploring APG990 for AD, and we believe combining two of the most active, orthogonal mechanisms of IL-13 (APG777) with OX40L (APG990) has the potential to expand patient reach with best-in-class efficacy and dosing. This approach underscores our relentless pursuit for the next wave of innovation in treating patients with AD. We refuse to stop at ‘good enough.’”
The APG990 Phase 1 clinical trial is designed as a double-blind, placebo-controlled, first-in-human, single-ascending dose trial in healthy volunteers. The study will evaluate the safety, tolerability and pharmacokinetics (PK) of APG990 and is expected to enroll approximately 40 healthy adults into 5 cohorts. Apogee expects interim data from the trial in 2025. Pending positive results from the Phase 1 clinical trial and following submission of an Investigational New Drug application or foreign equivalent, the company plans to initiate a Phase 1 clinical trial of APG777 and APG990 as a potential first-in-class approach to test the combination of deep and sustained inhibition of Type 2 inflammation via APG777’s targeted inhibition of IL-13 with broader inhibition of Type 1-3 inflammation through APG990’s inhibition of OX40L. The company plans to initiate the first clinical trial of the APG777 and APG990 combination in 2025.
“The progression of the APG990 program represents an important advancement in our efforts to enhance treatment options for patients with AD,” said Carl Dambkowski, M.D., Chief Medical Officer of Apogee. “AD is a heterogeneous disease where Type 2 inflammation is the core pathway with varying involvement of Type 1 and Type 3 inflammation. While currently available treatments are targeted at the Type 2 pathway, OX40L has been clinically validated to provide broad inhibition of all three inflammation pathways and could enhance treatment options for patients. We plan to investigate APG777 and APG990, our extended half-life mAbs, which could provide both deeper and broader responses, delivering the potential for better overall outcomes and best-in-class dosing for patients living with AD and other I&I diseases.”
About APG990
APG990 is a novel, SQ half-life extended mAb targeting OX40L, initially being developed for AD. OX40L is located further upstream in the inflammatory pathway than IL-13 or IL-4Rα and targeting it could potentially have broader impact on the inflammatory cascade by inhibiting Type 1, Type 2 and Type 3 pathways. AD is a heterogeneous disease and varies by age, severity and ethnicity. With current approved biologics only targeting two mechanisms of action (IL-13 and IL4Rα) in AD, OX40L could represent another therapeutic option for patients, especially the portion of patients who do not benefit from currently available treatments. In our head-to-head preclinical assays, APG990 has demonstrated similar or improved potency to amlitelimab. In our head-to-head studies of APG990 and amlitelimab in non-human primates, APG990 demonstrated a half-life of 26 days versus 21 days for amlitelimab. In addition, based on our preclinical studies, we believe APG990 can be dosed every three to six months in maintenance, which, if our clinical trials are successful, would represent a significant improvement compared to first generation OX40L antibodies that are expected to be dosed every four to twelve weeks.
About Apogee
Apogee Therapeutics is a clinical-stage biotechnology company advancing novel biologics with potential for differentiated efficacy and dosing in the largest inflammatory and immunology (I&I) markets, including for the treatment of atopic dermatitis (AD), asthma, chronic obstructive pulmonary disease (COPD) and other I&I indications. Apogee’s antibody programs are designed to overcome limitations of existing therapies by targeting well-established mechanisms of action and incorporating advanced antibody engineering to optimize half-life and other properties. APG777, the company’s most advanced program, is being initially developed for the treatment of AD, which is the largest and one of the least penetrated I&I markets. With four validated targets in its portfolio, Apogee is seeking to achieve best in class efficacy and dosing through monotherapies and combinations of its novel antibodies. Based on a broad pipeline and depth of expertise, the company believes it can deliver value and meaningful benefit to patients underserved by today’s standard of care.
