Inclusion criteria
. Male or female participant aged ≥ 18 years of age.
. Estimated life expectancy ≥12 weeks.
. Eastern Cooperative Oncology Group (ECOG) performance status \< 2.
. Women of childbearing potential (WOCBP) must use a highly effective method of birth control during study treatment until at least 6 months after the last dose of investigational medicinal product (IMP). In case of use of oral contraception, women should have been stable on the same contraceptive drug (i.e. same active principle) for at least 3 months prior to the first IMP administration.
. Male participants with WOCBP partners must use a condom during the study and until at least 6 months after the last dose of IMP. In addition, contraception should be considered for their female partners. Contraceptive measures do not apply if the participant is sterile, vasectomized or sexually abstinent. Sperm donation will not be allowed during the study and for 6 months after the last dose of IMP.
. Obtained informed consent (ICF) prior to any study-specific procedure.
. Participants with histologically confirmed advanced or metastatic esophageal squamous cell carcinoma that has failed to respond to or has progressed after treatment with standard fluorouracil and platinum-based chemotherapy, or with an anti-PD1 or PD-L1 antibody and not previously treated with a taxane.
. Participants who have received one or two prior lines of systemic therapy.
Exclusion criteria
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
Dose-limiting toxicities (DLTs) associated with S095033 administration during the first cycle of treatment (Phase 1)
Timeframe: At the end of Cycle 1 (each cycle is 28 days)
2
Adverse events (AEs) (Phase 1)
Timeframe: up to 28 days after the last IMP administration (for all AEs) or up to 4 years (for all SAE related to the research)
3
Changes in laboratory assessments (hematology and blood biochemistry) (Phase 1)
Timeframe: Screening, Day1(D1) D8 D15 and D22 from Cycle 1 to Cycle 4 (each cycle is 28 days),D1 and D15 from Cycle 5 (each cycle is 28 days) up to 28 days after the last IMP administration
4
Changes in physical examination and in performance status (ECOG) (Phase 1)
Timeframe: Screening, D1 and D15 of Cycle 1, D1 for all the remaining cycles up to 28 days after the last IMP administration
5
Abnormalities in 12-lead ECG parameters (Phase 1)
Timeframe: Screening, D1 and D2 of Cycle 1, D1 for all the following cycles until withdrawal visit (within 5 days after the last IMP administration)
6
Changes in vital signs: SBP, DBP, respiratory rate and temperature (Phase 1)
