Active clinical trials for "Colorectal Neoplasms"

230 patients with colorectal cancer liver metastases will be randomly assigned to resection or thermal ablation.

This project plans to use CIK combined with chemotherapy, immunotherapy and targeted therapy to treat CRC patients, so as to explore the effectiveness of CIK treatment and the CRC subtypes more suitable for CIK treatment, thereby improving the survival rate and quality of life of CRC patients.

Colorectal liver metastases (CLM) are currently considered an absolute contraindication for liver transplantation (Lt) although Lt for other primary and secondary liver malignancies show excellent outcome in selected patients. Before 1995, several Lts for CLM were performed, but the outcome was poor (18% 5-year survival) and Lt for CLM was stopped. Since then, several advances have been achieved and survival following Lt has improved by almost 30%. Thus, a 5-year survival of about 50% following Lt for CLM could be anticipated. The investigators have previously included 21 patients in a pilot study. All patients had advanced CLM at the time of Lt. Long term overall survival (OS) exceeds by far previously reported outcome for this patient group and is comparable or better than survival following repeat Lt for non-malignant diagnoses. Development of robust selection criteria may further improve the results. The investigators will conduct a randomized controlled trial to explore whether liver transplantation in selected patients with liver metastases from CRC can obtain significant life extension and better health related quality of life compared to patients receiving surgical resection. The investigators will also explore if patient selection according to nomo-grams for outcome of colorectal cancer can define a subgroup of patients with a 5 year survival of at least 50% or even cure from the disease.

This phase II trial tests how well CPI-613 (devimistat) in combination with hydroxychloroquine (HCQ) and 5-fluorouracil (5-FU) or gemcitabine works in patients with solid tumors that may have spread from where they first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that have not responded to chemotherapy medications (chemorefractory). Metabolism is how the cells in the body use molecules (carbohydrates, fats, and proteins) from food to get the energy they need to grow, reproduce and stay healthy. Tumor cells, however, do this process differently as they use more molecules (glucose, a type of carbohydrate) to make the energy they need to grow and spread. CPI-613 works by blocking the creation of the energy that tumor cells need to survive, grow in the body and make more tumor cells. When the energy production they need is blocked, the tumor cells can no longer survive. Hydroxychloroquine is a drug used to treat malaria and rheumatoid arthritis and may also improve the immune system in a way that tumors may be better controlled. Fluorouracil is in a class of medications called antimetabolites. It works by killing fast-growing abnormal cells. Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill tumor cells. CPI-613 (devimistat) in combination with hydroxychloroquine and 5-fluorouracil or gemcitabine may work to better treat advanced solid tumors.

This is an open-label, nonrandomized, Phase 2 clinical trial evaluating therapy with an oncolytic immunotherapy (RP2 or RP3) in combination with atezolizumab and bevacizumab in patients with advanced Microsatellite Stable and Mismatch Repair Proficient Colorectal Carcinoma.

The primary objective of the study is to estimate the antitumor efficacy of nanrilkefusp alfa (SOT101) in combination with cetuximab in RAS wild-type colorectal cancer.

This is an open-label, multicenter, randomized parallel-group phase 2 study evaluating the efficacy and safety of Fruquintinib alternating with Bevacizumab plus Capecitabine versus Bevacizumab plus Capecitabine as maintenance therapy following first-line treatment for metastatic colorectal cancer. Approximately 40 patients with metastatic colorectal cancer who have achieved partial remission after completing 8 cycles of standard first-line chemotherapy (FOLFOX combined with Bevacizumab) but are still in un-resectable state will be assigned to 2 maintenance treatment groups by randomization in a 1:1 ratio to receive Fruquintinib alternating with Bevacizumab plus Capecitabine (Arm A) or Bevacizumab plus Capecitabine (Arm B). The study contains a safety lead-in phase in which the safety and efficacy of Fruquintinib alternating with Bevacizumab plus Capecitabine will be assessed in approximately 20 patients. All patients from Arm A and Arm B will be treated until unacceptable toxicity, withdrawal of informed consent, death, or other criteria for ending the study (whichever occurs earlier). The study will evaluate PFS, ORR, DCR, OS and safety.

Hepatic metastases of colorectal cancer (CRC) are partially necrotic tumors mainly vascularized by the hepatic artery. When resectable, these metastases must be removed with a safety margin of 1 mm. Resection margins greater than 1 cm are associated with better disease-free survival and no local recurrence. Thermoablation systems allow for ablation zones of approximately 4.5-5 cm in diameter. For tumors <3 cm, subject to perfect targeting, it is possible to obtain ablation margins of 1 cm, which would greatly reduce the local recurrence rate. Accurate assessment of these tumor boundaries and characterization of these margins are paramount to ensure complete ablation. Thermoablation for these small liver metastases (<3cm) has shown equivalent efficacy to surgery in terms of recurrence and survival with fewer complications. Thermoablation treatment is indicated for patients with stable disease undergoing chemotherapy. This leads to liver remodeling and metastases become difficult to see on ultrasound and CT scans. The study authors hypothesize that the porto-scanner guidance technique with Angio-CT for thermoablation treatment of CRC liver metastases will allow a better exploration of these metastases by allowing a better identification of the margins and thus ensure a more accurate and complete treatment for patients.

This phase I/II trial studies the side effects and best dose of temozolomide and M1774 and how well they works in treating patients with cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and may have spread to nearby tissue, lymph nodes, or distant parts of the body (advanced). Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill tumor cells and slow down or stop tumor growth. M1774 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Adding M1774 to temozolomide may shrink or stabilize cancer for longer than temozolomide alone.

The current study is to investigate the safety and efficacy of fruquintinib combined with HAIC in patients with advanced colorectal liver metastases who have failed second-line systemic standard treatment, in order to provide more survival opportunities for the second progression of advanced colorectal liver metastases.
