Active clinical trials for "Colorectal Neoplasms"

This is a prospective, single-center, single-arm phase II clinical trial.This study aims to evaluate the safety and tolerability of stereotactic ablative radiotherapy (SABR) in combination with Fruquintinib and Tislelizumab, and to examine the impact of the combination therapy on tumor control, long-term survival and quality of life in patients with Metastatic colorectal cancer. A total of 68 metastatic colorectal cancer patients who have failed the first-line standard treatment, will be recruited and receive multisite SABR(8-12 Gy, 4-5 times) followed by fruquintinib(5mg, qd) and tislelizumab(200mg, q3w) within two weeks from completion.The overall response rate (ORR), disease control rate(DCR), progression-free survival(PFS) and overall survival(OS) will be analyzed.

Long course radiotherapy plus neoadjuvant chemotherapy followed by resection total mesorecta excision has accepted widespread recognized in the treatment of locally advanced rectal cancer (LARC). Tislelizumab, an anti-PD1(programmed death 1) humanized IgG4 (Immunoglomin G4) monoclonal antibody, has been demonstrated with clinical activity and is approved for treating recurrent/refractory classical Hodgkin lymphoma and locally advanced/metastatic urothelial carcinoma in China. The aim of This NCRT-PD-1-LARC trial is to evaluate the efficacy and safety of long course neoadjuvant chemoradiotherapy plus tislelizumab followed by total mesorecta excision for LARC. This NCRT-PD-1-LARC trial will be a prospective, multicenter and phase Ⅱ clinical trial designed to evaluate the safety and efficacy of LARC patients treated with long course neoadjuvant chemoradiotherapy plus tislelizumab followed by total mesorecta excision. It will consecutively enroll 50 stage II/III LARC patients (cT3N0M0 and cT1-3N1-2M0) with the tumor distal location ≤ 10cm from anal verge at 7 centers in China. The enrolled patients will receive long course radiotherapy (50 Gy/25 f, 2 Gy/f, 5 days/week) and three 21-day cycles capecitabine (1000 mg/m2, bid, po, day1-14) plus three 21-day cycles tislelizumab (200 mg, iv.gtt, day8), followed by total mesorecta excision 6-12 week after the end of radiotherapy. The primary efficacy endpoint will be the pathological complete response (pCR) rate, which is defined as absence of viable tumor cells in the primary tumor and lymph nodes.

This is a single arm phase II study of adjuvant intra-dermal NA DC vaccine combined with intravenous nivolumab in patients with resectable HCC (group A) or CRLM (group B) planned for curative surgery (with/without local ablation).

Immunotherapy has achieved significant therapeutic effect in DNA mismatch repair-deficient or microsatellite instability-high (dMMR/MSI-H) colorectal cancer (CRC). However, for proficient mismatch repair(pMMR)/microsatellite stable(MSS) CRC, the curative effect of PD-1 monoclonal antibody was poor and most of the data came from stage Ⅳ patients with distant metastasis. Among the whole CRC patients, more than eighty-five percent were pMMR/MSS CRC. It would be very inspiring when major CRC patients(pMMR/MSS) could be benefit from immunotherapy. For T4NxM0 CRC patients, R0 resection was difficult to achieve. If the patients could not got R0 resection, which means the tumors were almost destined to recurrent and patients life time were counting down. Whether combined treatment of mFOLFOX6+ Bevacizumab+PD-1 monoclonal antibody could maximize the curative effect was still unknown. This study aims to evaluate the effect and safety of mFOLFOX6+ Bevacizumab+PD-1 monoclonal antibody treatment combinations in patients with local advanced(T4NxM0) pMMR/MSS CRC.

Sintilimab (R&D code: IBI308) is a recombinant human-derived IgG4 type PD-1 monoclonal antibody. PD-1 inhibitor combined with chemotherapy has synergistic effect to further enhance anti-tumor immunity. This study is a phase III clinical study of a three-week regimen of sintilimab combined with the XELOX+ bevacizumab for RAS-mutant metastatic colorectal cancer patients who had not received any treatment before. The purpose of this study is to explore the efficacy of sintilimab combined with XELOX + bevacizumab as first line therapy.

This is an exploratory, non-controlled, multi-cohort, phase II small-sample clinical study designed to evaluate the clinical benefit of second-line treatment with anlotinib plus irinotecan or further in combination with a PD-1 monoclonal antibody (penpulimab) in patients with advanced colorectal cancer after first-line treatment failure. To explore the rationality of the combination of chemotherapy and targeted therapy and immunotherapy strategy and obtain relevant survival and safety data. The study will fully evaluate the efficacy, PFS, OS, safety and related biomarkers of the regimen.

The study consists of the two parts, phase IIa and phase IIb.

Doctors leading this study hope to learn about the safety of combining the study drug VS-6766 with another drug called cetuximab in colorectal cancer. This study is for individuals who have advanced colorectal cancer and their cancer has progressed while getting previous treatment or individuals who cannot take/tolerate previous treatments. If you choose to participate, your time in this research will last up to 24 months.

This study will take progression-free survival and overall survival as the main evaluation indexes, to evaluate the Efficacy of Jianpi Huatan Decoction in the Treatment of Advanced Colorectal Cancer. Decision Trees and Discriminant Analysis will be used to analyze the characteristics of dominant population combined with clinical data of patients. DNA methylation of the subjects will be detected to study the methylation characteristics of the preponderant population of Jianpi Huatan Decoction.

This feasibility (small) study aims to see if it is possible to run a large study looking at the effect of lidocaine on large bowel cancer recurrence after surgery in the NHS hospitals.
