This is the first compound in Zai’s portfolio of internally developed drugs to advance into Phase 2, demonstrating Zai’s global capabilities
Based on a proof-of-concept study, ZL-1102 is the first topical biologic to show penetration of psoriatic skin resulting in a clinical response
SHANGHAI, China & CAMBRIDGE, MA, USA I May 22, 2024 I Zai Lab Limited (NASDAQ: ZLAB; HKEX: 9688) today announced that the first patient has been dosed in a global Phase 2 clinical trial (NCT06380907) evaluating the efficacy and safety of the company’s internally developed anti-IL-17 investigational therapy, ZL-1102, for the treatment of chronic plaque psoriasis (CPP). ZL-1102 is a novel human VH antibody fragment (Humabody®) targeting the IL-17 cytokine. Emphasizing its unique approach, ZL-1102 is being developed as a topical treatment for mild-to-moderate CPP, differentiating it from other anti-IL-17 products that target moderate-to-severe forms of the disease through systemic administration.
“This study marks an important milestone in Zai’s evolution and is a testament to our outstanding internal R&D team’s commitment to develop novel therapies to help patients across the globe,” said Josh Smiley, President and Chief Operating Officer, Zai Lab.
“ZL-1102 is the first IL-17 targeted topical treatment in development for patients with less severe forms of CPP. Formulated to be applied directly to psoriatic skin lesions, we hope it can bypass unnecessary tissue exposure and avoid systemic toxicity commonly associated with intravenous or subcutaneous therapies,” said Harald Reinhart, M.D., President and Head of Global Development, Neuroscience, Autoimmune & Infectious Diseases, Zai Lab. “ZL-1102 exemplifies the innovative, patient-focused R&D programs in our internal discovery and development pipeline. We aim to bring this novel treatment option to patients in need as quickly as possible.”
Psoriasis affects about 125 million people worldwide; 80% to 90% of these individuals have plaque psoriasis and 70% to 80% of these cases are mild-to-moderate. Most systemic agents, i.e., oral and injectable medications, are prescribed for moderate-to-severe psoriasis. Zai Lab previously reported data from the proof-of-concept study in patients with mild-to-moderate CPP in which topical treatment with ZL-1102 showed a 45% relative improvement compared to placebo in the local Psoriasis Area Severity Index (PASI) score of the target lesion at four weeks, and consistently higher responder rates over time compared to placebo during and after the end of treatment.1
The Phase 2 global clinical trial of ZL-1102 is a randomized, double-blind, vehicle-controlled, dose-ranging study in patients with mild-to-moderate CPP. In this 5-arm trial, approximately 250 patients will receive topical therapy for 16 weeks. The primary endpoint is the proportion of patients achieving modified PASI75, which is at least a 75% reduction in the modified PASI score from baseline, at week 16. The study will also determine the efficacy of different doses of ZL-1102 compared to placebo at the end of therapy. Secondary objectives include efficacy throughout the treatment period, safety, tolerability, pharmacokinetics and anti-drug antibody (ADA).

About ZL-1102
ZL-1102 is an investigational, novel human VH antibody fragment, targeting the IL-17A cytokine, formulated as a hydrogel for topical use in the treatment of chronic plaque psoriasis. Due to its small size and other features unique to this class of molecules, ZL-1102 has improved target affinity and tissue penetration compared to full-sized monoclonal antibodies. With potentially improved safety and tolerability, this topical therapeutic may bring the potential of IL-17-targeted treatments to the large patient population with less severe CPP.
About Mild-to-Moderate Chronic Plaque Psoriasis
Plaque psoriasis is a common chronic, systemic, inflammatory autoimmune skin disease characterized by red patches and plaques with silvery scales on the skin. Psoriasis affects approximately 125 million people worldwide. Plaque psoriasis is the most common type, affecting 80%-90% of those with psoriasis. 70–80% of plaque psoriasis cases are mild-to-moderate, and marketed IL-17 inhibitors are currently not indicated for such cases. Topical therapies are the standard of care for treatment of mild-to-moderate disease. However, current treatment options provide limited efficacy or have safety concerns with long-term use.
