Brief Summary

This study was an open, multicenter Phase I/II clinical study of WJ05129 in patients with locally advanced or metastatic malignant solid tumors in China, which was divided into three stages: Single-dose escalation,Combined dose extension and efficacy extension. The study included screening, treatment and follow-up periods. The starting dose of this dose-escalation study was set at 2.5 mg/day. Five dose levels were preset.A more flexible "BOIN" dose escalation method was adopted. The maximum tolerated dose observation period was the first treatment cycle of single administration and multiple consecutive administrations (a total of 2 days) + 21 days = 23 days; In this stage, the two dosage levels of the injectable WJ05129 (RP2D dosage and the lower dose before RP2D) will be selected as the escalating doses for the combined use of WJ05129. The "BOIN" design will be adopted for dose escalation. Paclitaxel 80mg/m2 will be intravenously infused on days 1, 8, and 15. A 28-day cycle will be used, with the first cycle being the DLT observation period.Efficacy expansion phase: It is preliminarily planned to expand three cohorts of Rb negative TNBC and SCLC andOther solid tumors（Such as gastric and esophageal adenomas, gynecological tumors, etc.）, and recruit about 20-40 people in each cohort.
