A Phase I Clinical Study to Evaluate the Safety, Tolerability and Preliminary Efficacy of SSGJ-705 Monotherapy in Patients with Advanced Malignant Tumors

This study was an open-label phase I study to evaluate the safety, tolerability, PK profile and potential efficacy of SSGJ-705 as a single agent in patients with advanced malignancies.

This study includes 4 Parts: Part 1 (dose escalation and dose extension for QW administration), Part 2 (dose escalation and dose extension for Q2W administration), Part 3 (dose escalation and dose extension for Q3W administration), and Part 4 (indication extension, such as HER2 expression, PD-L1 high expression, driver gene negative newly treated advanced NSCLC, or other tumors).

Inclusion Criteria:

1. Males and/or females over age 18
2. Histologically and/or cytologically documented local advanced or recurrent or metastatic malignancies
3. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
4. Expected survival >3 months.
5. Signed informed consent form.
6. Must have adequate organ function.

Exclusion Criteria:

2. Pregnant or nursing women or women/men who are ready to give birth
3. Symptomatic central nervous system metastasis.
4. Allergy to other antibody drugs or any excipients in the study drugs.
5. Severe dyspnea at rest due to complications of advanced malignant tumors, or needing supplemental oxygen therapy.
6. Participated in any clinical study of medical devices or drugs within 1 month prior to screening (excluding non-intervention clinical studies or follow-up period of intervention clinical studies) .
