Evaluating the Efficacy of Chidamide in the Treatment of Initial Unresectable Metastatic Colorectal Cancer With High Expression of SULF1

Korábbi kezelés

• Previous or concurrent other active malignancy (except malignancies that have been treated with curative intent and have had no recurrence for more than 5 years, or carcinoma in situ that can be cured with adequate treatment).
• Major surgery such as laparotomy, thoracotomy, or laparoscopic organ resection, or severe trauma within the previous 2 weeks.
• Active coronary artery disease, severe/unstable angina, newly diagnosed angina, or myocardial infarction within 12 months before study participation.
• Thrombotic or embolic events within the previous 6 months, such as cerebrovascular accident (including transient ischemic attack), pulmonary embolism, or deep vein thrombosis.
• Any unresolved CTCAE grade 2 or higher toxicity caused by prior treatment (except anemia, alopecia, and skin pigmentation).
• Patients scheduled to undergo local treatment (surgery, intervention, radiotherapy, etc.) in the near future (within 2 months).
• Receipt of radiotherapy within < 4 weeks before the first dose of study drug, or receipt of chemotherapy, biological therapy, endocrine therapy, or small-molecule targeted therapy before the first dose of study drug (enrollment is permitted if the washout period is ≥ 5 half-lives from the first dose of study drug).
• Insufficient hematopoietic function or organ function (blood products such as transfusion are not permitted to correct this within ≤ 14 days before the first dose of study drug).

Más betegség

• The patient has severe infection, obstruction, active bleeding, or perforation and requires emergency surgery or stent placement.
• New York Heart Association (NYHA) class II or higher congestive heart failure.
• Known human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS)-related disease, or active hepatitis B or hepatitis C.
• Active inflammatory bowel disease or other colorectal diseases causing chronic diarrhea.
• History of known or suspected allergy to any relevant drug used in the study.
• Any medical condition that is unstable or may affect patient safety and study compliance.
• Vulnerable populations, including individuals with mental illness, cognitive impairment, critically ill patients, minors, pregnant women, illiterate individuals, etc.

Egyéb

• Patients meeting any of the following criteria will be excluded from the study:

• This study intends to enroll patients diagnosed with advanced colorectal cancer who are treated at Sir Run Run Shaw Hospital, Zhejiang University School of Medicine.
• Age ≥ 18 years.
• Voluntary participation in this study and signing of the informed consent form.
• Confirmed by definitive histological evidence as colon or rectal adenocarcinoma.
• ECOG performance status score of 0-1.
