I1. Is capable of giving signed informed consent, including compliance with the requirements and restrictions listed in the ICF and in this protocol.
I2. Is at least 18 years of age at the time of signing the ICF.
I3. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
I4. Life expectancy ≥ 12 weeks.
I5. Has adequate organ function.
I6. Pregnancy and Contraception: Female participants agree not to be pregnant or lactating from beginning of the study screening until 6 months after receiving the last treatment. Male participants with partners of childbearing potential and female participants of childbearing potential are willing and able to employ a highly effective method of birth control/contraception to prevent pregnancy from beginning of the study screening until 6 months after receiving the last treatment of MST-168.
I7. Has a pathologically documented advanced/unresectable or metastatic solid tumor that is refractory to or intolerable with standard treatment, or for which no standard treatment is available.
Exclusion Criteria:
* Participants are excluded from the study if any of the following criteria apply:
E1. Has untreated brain or CNS metastases or brain/CNS metastases that have progressed \[e.g., evidence of new or enlarging brain metastasis or new neurologic symptoms attributable to brain/CNS metastases\]. Participan…
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
Incidence of dose-limiting toxicities (DLT)
Timeframe: Day 1 - Day 28
2
Incidence and severity of AEs, clinically significant changes from Baseline (pre-dose on D1) through to the EOT in vital signs, laboratory tests, physical examinations, 12-lead ECG, and ECHO/MUGA.
Timeframe: Through study completion, up to 25 months
