Inclusion criteria
. Male or female, at least 18 years of age.
. Eastern Cooperative Oncology Group (ECOG) performance status score of 0 to 1.
. Estimated life expectancy \>12 weeks.
. Patients must have at least one assessable lesion in dose-escalation part and one measurable lesion in dose-expansion part per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

. Patients must have adequate organ function as defined in the below:
Questions worth asking your doctor
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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Phase I: Determine the dose-limiting toxicities (DLT) during the first 28-day cycle of SY-5007 treatment
Timeframe: Dose-escalation Cycle 1 (each cycle is 28 days)
2
Phase I: Number of patients with adverse events and serious adverse events
Timeframe: Up to 24 months
3
Phase II: Overall Response Rate (ORR) as assessed by RECIST 1.1 criteria
. Female patients with reproductive potential must have a negative serum pregnancy test within 7 days prior to the first dose, male and female patients of childbearing potential must be willing to completely abstain or agree to use an appropriate method of contraception during the entire study duration and for at least 3 months after the last dose of study medication.
. Willingness and ability to give informed consent and follow protocol procedures, and comply with follow-up visit requirements.
Exclusion criteria
. Dose-expansion Part: Patient's cancer has a known primary driver alteration other than RET. e.g. EGFR, ALK, ROS1, KRAS, etc.
. Dose-expansion Part: Patients previously treated with a selective RET inhibitor.
. Patients received systemic antitumor therapy, including chemotherapy, radiotherapy, biologic therapy, endocrine therapy, or immunotherapy within 3 weeks prior to the first dose, except for the following:
. Patients received other unlisted clinical trial drugs or treatments within 4 weeks prior to the first dose.
. Patients underwent major organ surgery (excluding puncture biopsy) or had significant trauma within 4 weeks prior to the first dose.
. Adverse effects of previous anti-tumor therapy have not recovered to CTCAE 5.0 grade rating of ≤ grade 1 (except for toxicity judged by the investigator be of no safety risk, such as alopecia, grade 2 peripheral neurotoxicity, etc.)
. Patients have symptomatic central nervous system (CNS) metastases, meningeal metastases, or a primary CNS tumor that is associated with progressive neurological symptoms.
. Patients with active uncontrolled systemic bacterial, viral, or fungal infection despite optimal treatment (chronic disease screening not required).
