A Phase I/II dose-escalation trial investigating the oncolytic virus TMV-018 in combination with a chemotherapy precursor (5-Fluorocytosine) or an immunotherapeutic agent (anti-PD-1 therapy) in patients with tumors of the gastrointestinal tract in terms of safety, clinical activity as well as pharmacokinetics and pharmacodynamics.

Phase 1
Conditions
Patients with histologically confirmed diagnosis of colorectal carcinoma (left-sided or rectal), esophageal carcinoma, or gastric cancer.

2. At least 18 years of age on the day of signing the informed consent.
3. Histologically confirmed diagnosis of tumors of the gastrointestinal tract (colo¬rectal cancer (left side or rectal), gastric cancer, esophageal cancer being accessible for endoscope guided injection (without intake of oral laxatives) and sub¬sequent repetitive biopsy taking.
4. Before enrolment (i.e., at least 4 weeks before study treatment): Prior chemotherapy, targeted therapy (e.g., bevacizumab), radiotherapy, to treat cancer or major surgery have to be stopped at least 4 weeks prior to enrolment.

informed consent), unstable angina pectoris, congestive heart failure (New York Heart Association Class II or above), or severe arrhythmia, which cannot be controlled with drugs or have potential impact on treatment.
4. Patients with other serious organic diseases or mental disorders.

16. Patients with active autoimmune disease.
17. Other medical condition or laboratory abnormality that in the judgment of the Investigator may increase the risk associated with study participation or may interfere with
interpretation of study results.
