This is a Phase I open, multi-center, first-in-human study evaluating JSKN016 in subjects with advanced metastatic solid tumors, divided into dose escalation and dose extension.
1. Subjects can understand the informed consent form, voluntarily participate in and sign the informed consent form; 2. The subjects were ≥18 years old on the day of signing the informed consent, male or female; 3. Subjects with histologically and/or cytologically confirmed advanced unresectable or metastatic epithelial malignancies that have failed or are intolerable to previous standard therapies, preferentially but not limited to the following types: AGA-positive non-small cell lung cancer, HER2 IHC 0 breast cancer, etc.
For the enrolled subjects, the above driver gene mutations were not tested, but the previous test results confirmed by the investigators were accepted;
If only EGFR overexpression without driver gene mutation can not be included;
Prior osimertinib therapy is required if EGFR T790M mutation is present;
1. Patients with symptoms of active central nervous system metastases, except those with stable parenchymal brain metastases as assessed by investigators, were defined as seizure-free for more than 12 weeks with or without the use of antiepileptic drugs; No need for glucocorticoids; At least one MRI showed that the patient was stable on imaging. Or stable after treatment for more than 1 month without symptoms; 2. Received any investigational drug within 28 days before dosing; 3. Receipt of other antineoplastic therapy within 28 days before dose or within 5 half-lives of previous antineoplastic drugs, whichever is shorter but requires a minimum of 14 days; Received Chinese herbal medicine with clear anti-tumor indications within 14 days before drug administration; 4. Local palliative treatment within 14 days before administration; 5. Major surgical treatment (such as transabdominal or transthoracic surgery) within 28 days before drug administration; Excluding minor procedures such as diagnostic punctures or infusion device implantation or biliary stenting) or anticipated need for major surgical treatment during the study period; 6. Gastrointestinal abnormalities with obvious clinical manifestations, including but not limited to: intestinal obstruction or the presence of symptoms and signs of intestinal obstruction within 6 months before drug administration, but if the obstruction was completely removed after surgical treatment, screening could be performed (patients with previous intestinal stent implantation and the intestinal stent was not removed during the screening period were not allowed); Patients with gastrointestinal perforation, gastrointestinal fistula, intra-abdominal abscess and non-gastrointestinal fistula (such as tracheoesophageal fistula) within 6 months before administration; Patients with gastrointestinal bleeding (CTCAE≥ grade 3) within 6 months before treatment, or gastrointestinal bleeding (melena, bloody stool, etc.) within 1 month before randomization were eligible if hemorrhoid bleeding was confirmed or only showed positive fecal occult blood.
Active HBV or HCV infection Patients with HBsAg (+) and HBV-DNA< 2500 copies /mL or 500 IU/mL were allowed to be enrolled. HCV-Ab (+) and HCV-RNA negative were allowed to enroll.
