Apogee Therapeutics, Inc. (NASDAQ:APGE) on Tuesday shared interim data from the Phase 1b trial of zumilokibart (APG777) in patients with mild-to-moderate asthma.

The data covers 19 adult patients with mild-to-moderate asthma. The trial also evaluated fractional exhaled nitric oxide (FeNO) suppression, a key biomarker of Type 2 inflammation. Zumilokibart demonstrated:

Robust and durable suppression of FeNO, a biomarker of Type 2 inflammation that has shown the strongest correlation with exacerbations in asthma, following a single dose.

Data

Maximum absolute mean FeNO reduction of 45 ppb (60% decrease from baseline) after a single dose.

Durable FeNO suppression through 16 weeks for all patients. Suppression of FeNO through 32 weeks for patients with available follow-up, supporting potential for 3- or 6-month dosing.

Positive trends were observed in forced expiratory volume in one second (FEV1) and across Type 2 biomarkers for all available data. FEV1 is a pharmacodynamic measure of lung function.

Zumilokibart was well-tolerated in patients with mild-to-moderate asthma. No conjunctivitis, injection site reactions, or anti-drug antibodies were observed.
