InnoCare Announce First Subject Dosed in Phase 1 Clinical Trial of ICP-054, a Novel Potentially Best-in-Class Oral IL-17AA/AF Inhibitor

– Phase 1 trial designed to evaluate the safety, tolerability, and pharmacokinetic properties of ICP-054 (ZB021) in healthy volunteers 
– Phase 1 SAD and MAD data expected by year-end 2026

BEIJING, May 13, 2026 (GLOBE NEWSWIRE) — InnoCare Pharma (HKEX: 09969; SSE: 688428), a leading biopharmaceutical company focusing on the treatment of cancer and autoimmune diseases, announced today that the first subject has been dosed in the Phase 1 trial of ICP-054 (ZB021), a novel potentially best-in-class oral IL-17AA/AF inhibitor.

The Phase 1 trial is supported by robust preclinical data demonstrating a desirable pharmacology and toxicology profile. In addition to potent inhibition of IL-17AA/AF signaling, and anti-inflammatory activity demonstrated in preclinical animal models, excellent oral bioavailability was observed across multiple preclinical species, including non-human primates. Together, these data support the potential of ICP-054 to be a differentiated oral therapy for autoimmune and inflammatory diseases associated with dysregulated IL-17 signaling.

The Phase 1 study is designed to evaluate the safety, tolerability, and pharmacokinetic profile of single ascending doses (SAD) and multiple ascending doses (MAD) of ICP-054 in healthy volunteers and is being conducted in partnership with Zenas BioPharma in China. These data are expected by year-end 2026. Upon completion of the study, InnoCare plans to advance clinical development of ICP-054 to establish its proof-of-concept in the field of autoimmune diseases.

Dr. Jasmine Cui, the Co-founder, Chairwoman, and CEO of InnoCare, said, “We are committed to developing innovative drugs in the field of autoimmune diseases. We will accelerate the clinical development of the oral IL-17, and we believe that this novel therapy will become a better treatment option for patients with autoimmune diseases.”

About ICP-054 (ZB021)

ICP-054 is a novel potentially best-in-class oral small molecule IL-17AA/AF inhibitor being developed by InnoCare in partnership with Zenas BioPharma. ICP-054 is designed to selectively block the signal transduction pathways of both the IL-17AA homodimer and IL-17AF heterodimer, inhibiting downstream pro-inflammatory cytokine and chemokine release. Preclinical studies have demonstrated potent anti-inflammatory activity, a favorable safety profile, and excellent Absorption, Distribution, Metabolism, and Excretion (ADME) properties. The IL-17 pathway has demonstrated broad utility across many rheumatic and dermatologic indications. Currently, no oral IL-17 inhibitors have been approved or are in late-stage development globally. ICP-054’s oral, small molecule profile may offer meaningful advantages over currently approved biologic IL-17 therapies in terms of convenience, compliance, and accessibility. Zenas BioPharma licensed the exclusive rights from InnoCare Pharma to develop, manufacture, and commercialize ICP-054 in all fields of use worldwide, excluding greater China and Southeast Asia.
