Inclusion criteria
. Patients must be able to provide documented voluntary informed consent.
. Male or female patient aged 18-75 years.
. Histologically documented, incurable, locally advanced or metastatic epithelial origin malignant cancer, priority to include but not limited to the following tumor types:

. Patients should have an unresectable locally advanced or metastatic solid tumor that is refractory to standard therapies, or have no standard therapies, or standard treatment is not applicable at this stage.
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

What they're measuring
1
Phase I: Maximum Tolerated Dose (MTD) and Recommended Doses for Expansion (RDEs)
Timeframe: Assess up to 12 months
2
Phase II: Objective Response Rate (ORR)
Timeframe: From date of enrollment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 12 months
. International normalized ratio (INR) and activated partial thromboplastin time (aPTT) ≤ 1.5×ULN.
. Serum bilirubin ≤ 1.5 mg/dL (Patients with known Gilbert disease who have serum bilirubin level ≤ 3 ×ULN may be enrolled)., aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase ≤ 2.5 × upper limit of normal (ULN), with the exception of patients with hepatic metastases (ALT and AST ≤ 5 × ULN) and patients with hepatic and/or bone metastases (alkaline phosphatase ≤ 5 × ULN).
Exclusion criteria
. Severe or uncontrolled cardiac disease requiring treatment, congestive heart failure (New York Heart Association) III or IV, unstable angina pectoris even if medically controlled, history of myocardial infarction during the last 6 months, serious arrhythmias requiring medication (with exception of atrial fibrillation or paroxysmal supraventricular tachycardia).
. Symptomatic brain metastases or any radiation or surgery for brain metastases within 1 months of first infusion of study drug.
. Subjects with second primary cancers (except for cured in situ non-melanoma skin cancer and in situ cervical cancer with no relapse in the last 3 years).
. Require supplemental oxygen for daily activities.
. Documented Grade ≥ 2 peripheral neuropathy.
. History of documented severe dry eye syndrome, severe Meibomian gland disease and/or blepharitis, corneal disease that prevents/delays corneal healing, macular degeneration.
. Subjects previously treated with TROP 2 targeted therapies.
. Any standard cancer therapy (e.g. chemotherapy, hormonal therapy, radiotherapy, immunotherapy, biologic therapy treatment, or therapy with traditional Chinese medicines approved for anti-tumor treatment, etc.) within 4 weeks or five half-lives, whichever is shorter, of first infusion of study drug.
