Clinical trials

The goal of this clinical trial is to learn if investigational drug called SYS6043 works in adults with advanced or metastatic solid tumors that have spread or cannot be treated with standard therapies. The main goals of the study are to understand how safe SYS6043 is, what side effects it may cause, and what dose can be given safely. Researchers will also study how the drug moves through the body and whether the immune system reacts to it. In addition, the study will look for early signs that SYS6043 may help slow or shrink tumors and explore whether the amount of a tumor protein called B7-H3 is related to how well the treatment works. Participants will: * Provide written informed consent * Undergo screening tests to ensure they are eligible for study treatment * Attend all required study visits and receive SYS6043 by intravenous infusion once every 3 weeks (Q3W), with 21 days as one treatment cycle until the study doctor determines that study treatment should be stopped based on how well a participant is doing on treatment. * Have safety follow-up (SFU), and long-term follow-up. * Be followed until progression.

The goal of this clinical trial is to test CPO301, a type of drug called an antibody drug conjugate in adult patients with advanced or metastatic solid tumors. The main questions it aims to answer are: * To assess the safety and tolerability of CPO301 at increasing doses and determine the dose to be used in the second part of the study (Part A) * To assess the safety and tolerability of CPO301 at the dose determined to be safe and tolerable in Part A in patients with Non-Small Cell Lung Cancer and potentially other tumor types (Part B) * To evaluate how quickly CPO301 is metabolized by the body (pharmacokinetics or PK) * To evaluate if antibodies to the study drug develop (immunogenicity) * To evaluate preliminary efficacy to the drug * To correlate preliminary efficacy with mutations in a biomarker called EGFR Participants will: * Provide written informed consent * Undergo screening tests to ensure they are eligible for study treatment * Attend all required study visits and receive CPO301 by intravenous injection every 3 weeks until the study doctor determines study treatment should be stopped, based on how well a participant is doing on treatment * Be followed for progression every 3 months for up to 2 years

The goal of this clinical trial is to test JMT108, a type of drug called a bispecific antibody in adult patients with locally advanced or metastatic solid tumors. The main questions it aims to answer are: * To assess the safety and tolerability of JMT108 at increasing doses and determine the dose and schedule to be used in the second part of the study (Phase 1a) * To assess effectiveness of JMT108 in participants with locally advanced or metastatic tumors (Phase 1b) * To evaluate how quickly JMT108 is metabolized by the body (pharmacokinetics or PK) * To evaluate if antibodies to the study drug develop (immunogenicity) * To evaluate preliminary efficacy to the drug * To explore the pharmacodynamic (PD) characteristics of JMT108 * To explore the correlation between biomarker levels and preliminary efficacy Participants will: * Provide written informed consent * Undergo screening tests to ensure they are eligible for study treatment * Attend all required study visits and receive JMT108 by intravenous injection every 2 weeks until the study doctor determines study treatment should be stopped, based on how well a participant is doing on treatment * Be followed for progression every 3 months for up to 2 years
