A Phase 3, Multicenter, Randomized, Open-Label, Active-Controlled Trial Of JSKN003 Versus Treatment Of Physician'S Choice For HER2-low, Unresectable and/or Metastatic Breast Cancer Subjects

This study is a randomized controlled, open-label, multicenter phase III clinical study evaluating the efficacy and safety of chemotherapy selected by investigator JSKN003 s in subjects with recurrent or metastatic breast cancer who have previously failed first- or second-line chemotherapy in subjects with recurrent or metastatic breast cancer who have failed prior first- or second-line chemotherapy.
The study planned to enroll 400 subjects in a 1:1 ratio and stratified block randomization method assigned to:
Experimental group: JSKN003 monotherapy
Control group: investigator's chosen chemotherapy drug (capecitabine, gemcitabine, vinorelbine, docetaxel, albumin-bound paclitaxel, or eribulin) monotherapy

[Translation] A randomized, open, parallel-controlled, multicenter phase III clinical study of JSKN003 versus investigator-selected chemotherapy in the treatment of recurrent/metastatic breast cancer with low HER2 expression

JSKN003对比研究者选择化疗在复发/转移性乳腺癌患者中的由盲态独立中心评价的无进展生存期；JSKN003对比研究者选择化疗在复发/转移性乳腺癌患者中的总生存期；JSKN003对比研究者选择化疗在复发/转移性乳腺癌患者中的由BICR评价其他疗效指标和研究者评价疗效指标；JSKN003对比研究者选择化疗在复发/转移性乳腺癌患者中的安全性；JSKN003对比研究者选择化疗治疗复发/转移性乳腺癌的患者报告结局；评价JSKN003的药代动力学（PK）特征、免疫原性（ADA）；评价JSKN003药品暴露水平与疗效、安全性的相关性；评价生物标志物与JSKN003疗效的相关性。

[Translation]

JSKN003 compares the progression-free survival evaluated by a blinded independent center with chemotherapy selected by the investigator in patients with recurrent/metastatic breast cancer; JSKN003 compares the overall survival with chemotherapy selected by the investigator in patients with recurrent/metastatic breast cancer; JSKN003 compares other efficacy indicators evaluated by BICR and efficacy indicators evaluated by the investigator in patients with recurrent/metastatic breast cancer; JSKN003 compares the safety of chemotherapy selected by the investigator in patients with recurrent/metastatic breast cancer; JSKN003 compares patient-reported outcomes of chemotherapy selected by the investigator for the treatment of recurrent/metastatic breast cancer; evaluate the pharmacokinetic (PK) characteristics and immunogenicity (ADA) of JSKN003; evaluate the correlation between the drug exposure level of JSKN003 and its efficacy and safety; evaluate the correlation between biomarkers and the efficacy of JSKN003.

Phase I/II Clinical Study Evaluating the Safety, Tolerability, Pharmacokinetics/Pharmacodynamics, and Antitumor Activity of JSKN003 in Chinese Subjects With Advanced Solid Tumors

This is an open, multicenter study of stage I/II in Chinese subjects with unresectable locally advanced/metastatic solid tumors. It is divided into dose escalation period and cohort expansion period. A total of 9 dose groups (Q3W on the first day of intravenous administration every three weeks) were designed in the dose escalation period. The initial dose was 1.0mg/kg, Q3W, and the observation period of DLT was 21 days. In the dose expansion phase, 5 cohorts were set up.
