ZG005 plus gecacitinib for advanced non-small cell lung cancer

A Multicenter, Open-label, Dose-Escalation and Dose-Expansion Phase I/II Study of ZG005 Combined With Gecacitinib in Patients With Advanced Non-Small Cell Lung Cancer

Phase1; Phase2 Interventional Suzhou Zelgen Biopharmaceuticals Co.,Ltd · NCT06903377

This trial tests whether giving ZG005 by injection together with oral gecacitinib is safe and may help adults 18–75 with advanced non-small cell lung cancer that progressed after PD‑1/PD‑L1 therapy.

What this trial studies

This is a multicenter Phase 1/2 trial of ZG005 combined with gecacitinib in adults with locally advanced, recurrent, or metastatic non-small cell lung cancer who have failed prior PD‑1/PD‑L1 therapy. The Phase 1 portion focuses on defining safety, tolerability, and an appropriate dose or regimen of the combination, while the Phase 2 portion examines preliminary anti-tumor activity. Key eligibility includes histologically confirmed squamous or non-squamous NSCLC, age 18–75, and unsuitability for curative therapy; patients with central nervous system metastases or other malignancies within 5 years are excluded. Participants will receive ZG005 injections and oral gecacitinib with clinical and radiologic follow-up to monitor adverse events and tumor response.

Who should consider this trial

Good fit: Adults aged 18–75 with locally advanced or metastatic squamous or non-squamous NSCLC who progressed on PD‑1/PD‑L1 therapy and do not have CNS metastases or recent other cancers are ideal candidates.

Not a fit: Patients with brain metastases, another malignancy within the past five years, or those judged unsuitable by the investigator are unlikely to benefit or be eligible for this trial.

Why it matters

Potential benefit: If successful, the combination could offer a new treatment option for patients whose NSCLC has progressed after PD‑1/PD‑L1 therapy.

How similar studies have performed: Combining antibody therapies with JAK-pathway inhibitors is an emerging approach with limited early-phase data and some preliminary signals but has not yet been proven in larger trials.
