Active clinical trials for "Colorectal Neoplasms"

This phase II trial studies whether tucatinib combined with trastuzumab and TAS-102 works to shrink tumors in patients with HER2 positive colorectal cancer that has spread to other parts of the body (metastatic) and has one of the following gene mutations detected in blood: PIK3CA, KRAS, NRAS, or BRAF V600. Tucatinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals tumor cells to multiply. This helps stop or slow the spread of tumor cells. Trastuzumab is a form of targeted therapy because it attaches itself to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When trastuzumab attaches to HER2 receptors, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. TAS-102 is a combination of 2 drugs; trifluridine and tipiracil. Trifluridine is in a class of medications called thymidine-based nucleoside analogues. It works by stopping the growth of tumor cells. Tipiracil is in a class of medications called thymidine phosphorylase inhibitors. It works by slowing the breakdown of trifluridine by the body. Giving tucatinib, trastuzumab, and TAS-102 together may work better than usual treatment for metastatic colorectal cancer.

A small number of colorectal cancer patients with limited oligometastases may be candidates for local treatment of metastases (e.g., resection, ablation). However, it is unclear if patients with more extensive metastatic disease benefit from local therapies to control visible metastasis. The purpose of this study is to assess the impact of stereotactic body radiation therapy (SBRT) in combination with systemic therapy compared to systemic therapy alone on safety and efficacy in patients with metastatic colorectal cancer (mCRC) and ≤10 metastases.

This is a Phase 3, multicenter, randomized and double-blind study assessing the interchangeability between TRS003 and China-approved Bevacizumab® (also called China-approved Avastin) for first-line treatment of patients with metastatic Colorectal Cancer (CRC), approximately 126 patients will be enrolled in this study. Patients who sign the informed consent, meet the eligibility criteria and are confirmed as non-progressors after lead-in treatment period with Bevacizumab® in combination with modified FOLFOX6 chemotherapy for 6 cycles, will be randomized (1:1) to either the non-switching arm and receive Bevacizumab® + modified FOLFOX6 for all subsequent cycles or to the switching arm and receive TRS003 alternating with Bevacizumab® in combination with mFOLFOX6 until disease progression or intolerability.

Many studies have confirmed the analgesic effect of intravenous infusion of lidocaine in abdominal surgery. Transversus abdominis plane (TAP) block is also often recommended for abdominal surgery. Ropivacaine TAP block and intravenous lidocaine infusion are important components of multimodal analgesia for colorectal surgery. However, both of them are the local anesthetics and the safety of combination is unknown, so we design the study to explore the safety of the synergistic application of ropivacaine TAP block and intravenous lidocaine infusion in patients undergoing colorectal surgery.

Objective: To investigate the efficacy, safety and tolerability of SI-B003 monotherapy and BL-B01D1+SI-B003 dual agents in patients with locally advanced or metastatic esophageal cancer, gastric cancer, colorectal cancer and other gastrointestinal tumors, and to further explore the optimal dose and mode of combination.

This study is a phase Ⅱ, randomized, controlled, open-label, multi-center study with safety run-in to evaluate the efficacy and safety of JMT101 combined with Irinotecan and SG001 in Patients with Metastatic Colorectal Cancer (mCRC).

To find the recommended dose of ulixertinib that can be given in combination with cetuximab and/or encorafenib to patients with unresectable/metastatic CRC and who have received EGFR or BRAF-directed therapy in the past.

Approximately two-thirds of all colorectal cancer patients undergo surgery with the aim of curing them. However, despite the surgery, 20-25% of them experience relapse. It is possible to reduce the risk of relapse with chemotherapy, but as chemotherapy is associated with significant side effects, it is only given to patients at high risk of relapse. Currently, the risk is assessed based on an examination of the removed tumor tissue. In a previous research project, blood samples were taken after patients' surgery and examined for the presence of circulating tumor DNA (ctDNA). When cancer cells in solid tumors die, they release DNA, which can be detected in the blood. DNA in the blood has a half-life of less than 2 hours, so if ctDNA is found in a blood sample taken, e.g., 14 days after surgery, the patient most likely still has cancer cells in their body. The results show that if a patient has ctDNA in their blood after surgery, the risk of relapse is high. The presence of ctDNA in the blood has the potential to be a better indicator of the risk of future relapse than the tumor examination used today. Therefore, ctDNA analysis has the potential to become a marker that will be used in the future clinical setting for monitoring colorectal cancer. The overall objective of this study is to confirm that ctDNA found in a blood sample after intended curative treatment for CRC is a marker of residual disease and risk of recurrence and is applicable in clinical practice.

This study is to validate the safety and feasibility of ArtiSential (Articulating laparoscopic instrument) colorectal surgery and compare it with robotic surgery for patients with rectal cancer and rectosigmoid junction cancer.

RAS mutations are found in nearly half of colorectal cancer patients. However, there is no targeted driver gene drugs have been approved for RAS-mutated patients. For RAS mutant metastatic colorectal cancer, the commonly used treatment regimen is bevacizumab combined with chemotherapy.
