“We are encouraged by these initial results, which further highlight the potential of TSLP inhibition, a clinically validated target that plays an important role in promoting immune cell recruitment and activation,” said Carl Dambkowski, M.D., Chief Medical Officer of Apogee. “APG333’s PK profile supports the potential for dosing two to four times a year, a significant advancement over the current standard of care. These data unlock our combination of APG777 and APG333, which together demonstrated suppression of complementary pathways implicated in obstructive airway disease and may enable quarterly or less frequent dosing, expanding options for patients with limited available treatments.”
About APG333
APG333 is a novel, SQ extended half-life mAb targeting TSLP, an epithelial cell-derived cytokine that has emerged as an attractive, clinically validated target for the treatment of I&I indications because the target plays an important role in promoting immune cell recruitment and activation. In addition, a TSLP-targeting mAb may be used in combination with other mAbs for potentially greater efficacy in broader populations. TSLP inhibition has been clinically validated, with one approved product on the market for the treatment of severe asthma without biomarker or phenotype restrictions.
About Apogee
Apogee Therapeutics is a clinical-stage biotechnology company advancing optimized, novel biologics with potential for best-in-class profiles in the largest I&I markets, including for the treatment of Atopic Dermatitis (AD), asthma, Eosinophilic Esophagitis (EoE), 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 profiles 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.
