Clinical Trial Summary

This is an open-label, single center, non-randomized, phase Ⅱ trial to evaluate safety and efficacy of using the combination treatment of Camrelizumab with anti-angiogenic drugs and Chemotherapy of metastatic colorectal mucinous adenocarcinoma(MAC).

Description:

Colorectal cancer contains multiple pathological types, and one of the more special pathological types is mucinous adenocarcinoma. The prognosis of patients with mucinous adenocarcinoma is not ideal.Some molecular and genetic factors may be related to the characteristics of mucinous adenocarcinoma, in which microsatellite instability and loss of mismatch repair proteins are a focus of current research. Microsatellite instability is often associated with poor differentiation and higher tumor stage. Adenocarcinoma that secretes a large amount of mucus in pathological features.so,In this study, the incidence of ORR and AEs was the main endpoint, and the efficacy and safety of Camrelizumab combined with anti-angiogenic drugs in the treatment of advanced colorectal mucinous adenocarcinoma were observed and evaluated.

• 7. Estimated survival time> 3 months;

• 8. Willing to accept long-term follow-up, willing to provide tumor tissue samples, willing to provide blood samples before and after treatment;

Exclusion Criteria:

• 1. Known predisposition of inherited or acquired bleeding and thrombosis (such as hemophiliacs, coagulopathy, thrombocytopenia, etc.);

• 2. Urinary routines suggest that urine protein = ++ and a confirmed 24-hour urine protein amount> 1.0 g;

• 3. Suffering from active infection, or unexplained fever within 7 days before medication = 38.5?, or baseline white blood cell count> 15×109/L;

• 5. Active autoimmune diseases (such as vitiligo, psoriasis, hypothyroidism requiring hormone replacement therapy, etc.);

• 6. Patients with active hepatitis B or C, HIV patients, active tuberculosis, etc.;

• 7. Active infection requires antimicrobial treatment (for example, antibacterial drugs, antiviral drugs, antifungal drugs);

• 8. Known history of allogeneic organ transplantation and history of transplanted hematopoietic stem cells;

• 9. Patients with interstitial lung disease or previous history of interstitial pneumonia;

• 10. Those who have a history of psychotropic substance abuse and are unable to quit or have mental disorders;

• 11. Participated in clinical trials of other anti-tumor drugs within 2 weeks before enrollment;

• 12. Those who have used PD-1/PD-L1 and other immunotherapy drugs before entering the group;

• 13. Previous or concurrently suffering from other uncured malignant tumors, cured skin basal cell carcinoma, cervical carcinoma in situ, and superficial bladder cancer can be included;

• 14. Pregnant or lactating women; those with fertility who are unwilling or unable to take effective contraceptive measures;

• 15. According to the investigator's judgment, there are other factors that may affect the results of the study or lead to the forced termination of the study, such as alcoholism, drug abuse, other serious diseases (including mental illness) need to be treated together, and there are serious laboratory abnormalities , Accompanied by family or social factors, will affect the safety of the subject.
