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.
- Documented progression on prior line of therapy.
- Participants must have at least one measurable lesion, as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 for solid tumors.
- For participants with MTAP deletion, evidence of homozygous loss of MTAP in archival or fresh tumor tissue.
- For participants with MTAP wild type, evidence of the presence of MTAP in archival or fresh tumor tissue.
- Adequate hematological function based on the last assessment performed within 7 days prior to the first IMP administration.
- Adequate coagulation function for all participants. For participants receiving anti- coagulant therapy (except platelet anti-aggregants), the adequate therapeutic levels of INR should be confirmed.
- Adequate renal function based on the last assessment performed within 7 days prior to the first IMP administration.

- History of gastrointestinal perforation and /or fistula or aorto-esophageal fistula within 6 months prior to randomization.
- Apparent tumor invasion into organs located adjacent to the esophageal disease site (e.g. aorta or respiratory tract) at an increased risk of fistula in the study treatment assessed by investigator.
- Have a degenerative retinal disease that could increase the risk for visual loss with S095033 or confound the interpretation of retinal changes in the course of S095033 treatment.
- Severe or uncontrolled active acute or chronic infection.
- Participants with a known clinically significant cardiovascular disease or condition.
- Participants with thrombosis, or a history of deep vein thrombosis or pulmonary embolism, within 4 weeks prior to first IMP administration.

The participants will also receive paclitaxel intravenously on D1, D8 and D15 last for 28 days. Dose expansion - phase 2: Participants with MTAP-deletion and those with MTAP-wild type tumors will be evaluated in separate and independent dose expansion subpopulations.S095033 will be administrated every day during a 28-day cycle at recommended phase 2 dose (RP2D). Paclitaxel given intravenously on D1, D8, and D15 during a 28-day cycle. |

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
IPD Plan Description
Qualified scientific and medical researchers can request access to anonymized patient-level and study-level clinical trial data.
Access can be requested for all interventional clinical studies:
- used for Marketing Authorization (MA) of medicines and new indications approved after 1 January 2014 in the European Economic Area (EEA) or the United States (US).
- where Servier is the Marketing Authorization Holder (MAH). The date of the first MA of the new medicine (or the new indication) in one of the EEA Member States will be considered for this scope.
In addition, access can be requested for all interventional clinical studies in patients:
- sponsored by Servier.
- with a first patient enrolled as of 1 January 2004 onwards.
- for New Chemical Entity or New Biological Entity (new pharmaceutical form excluded) for which development has been terminated before any Marketing authorization (MA) approval.
