Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with histologically confirmed locally advanced or metastatic neuroendocrine carcinomas or other selected solid tumors who progressed after platinum-based therapy, have at least one measurable lesion, ECOG 0–1, and can provide tumor tissue for testing.

Probably not a fit

Patients with active central nervous system or leptomeningeal metastases, another progressing malignancy that requires treatment, prior exposure to ADCs with topoisomerase I payloads, or poor performance status (ECOG ≥2) are unlikely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This open-label, multicenter Phase 1b/2 study gives ZL-1310 to adults with selected advanced or metastatic solid tumors to characterize safety, tolerability, and preliminary anti-tumor activity. Participants must have measurable disease, ECOG performance status 0–1, life expectancy of at least three months, and must provide a tumor biopsy or archived tissue. Key exclusions include clinically active CNS or leptomeningeal metastases, another progressing malignancy requiring treatment within the past two years, prior treatment with antibody-drug conjugates carrying topoisomerase I payloads, and recent systemic anti-cancer therapy. The trial is run at multiple Zai Lab sites in the United States and follows a Phase 1b/2 design with dose-finding and expansion elements.

Why it matters

Potential benefit: If successful, ZL-1310 could provide a new treatment option that shrinks tumors or controls disease in patients whose cancers no longer respond to platinum chemotherapy.

How similar studies have gone: Similar antibody-drug conjugates delivering topoisomerase I inhibitors have shown activity in several solid tumors, so the approach has clinical precedent even though ZL-1310 itself is novel.
