Overview
Brief Summary
This is a multicenter, open-label Phase I/II study consisting of two parts:
Part 1 is a Phase I dose-escalation study of ZG006, aimed at evaluating the safety and tolerability of ZG006 in Participants with advanced small-cell lung cancer or neuroendocrine carcinoma. Upon completion of Part 1, the investigators and sponsor will jointly determine two preliminary recommended Phase II doses for Part 2, based on the available safety, preliminary efficacy, and pharmacokinetic data.
Part 2 is a Phase II dose-expansion study of ZG006, designed to explore and confirm the efficacy and safety of ZG006 monotherapy in advanced small-cell lung cancer.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Fully understand the study and voluntarily sign the informed consent form;
- •Male or female 18\~75 years of age;
- •Eastern Cooperative Oncology Group(ECOG) Performance Status of 0 or 1;
- •Life expectancy ≥ 3 months;
- •Participants with histologically or cytologically confirmed advanced solid tumors who also fulfill the following: Part 1: advanced small-cell lung cancer (SCLC) or neuroendocrine carcinoma.Part 2: advanced SCLC.Specifically for Part 2 Cohort 1: de-novo SCLC (composite SCLC excluded).Stage 2 restricted to third-line or later.Cohort 2: transformed SCLC.Cohort 3: large-cell neuroendocrine carcinoma of the lung and composite SCLC.
Exclusion Criteria

Arms & Interventions
Part1 ：Dose Escalation
A total of six dose escalations were preset: 0.1 mg, 0.3 mg, 1 mg, 3 mg, 10 mg, and 30 mg.
Intervention: ZG006
Part2 ：Dose Expansion
Part 2 consists of three cohorts. Cohort 1 is divided into two stages: Stage 1 is for dose optimization: approximately 30 patients will be enrolled in each of the two preliminary RP2D groups; the better-performing dose will be selected for Stage 2 based on emerging data. Stage 2 is the pivotal, registrational study, intended to enroll patients with advanced small-cell lung cancer who are in third-line or later lines of therapy.
Intervention: ZG006
Outcomes
Primary Outcomes
Objective response rate (ORR)
Time Frame: up to approximately 2 years
ORR is defined as the percentage of participants achieving a confirmed complete response (CR) or partial response(PR) based on RECIST 1.1 criteria.
Secondary Outcomes
- Duration of response (DOR)(Up to approximately 2 years)
- Disease control rate (DCR)(Up to approximately 2 years)
- Number of participants with adverse events (AEs)(Up to approximately 2 years)
- Number of participants with serious adverse events (SAEs)(Up to approximately 2 years)
