Active clinical trials for "Colorectal Neoplasms"

The goal of this laboratory research is to look for genetic and epigenetic markers that can predict which patients with stage III colorectal cancer will benefit from fluorouracil-based adjuvant chemotherapy.

Primary objectives: Use both listed and relatively safe drug, Silymarin,s to improve the intestinal side effect of the patients undergoing FOLFIRI chemotherapy.

The immune system plays an important role in helping to kill and prevent cancers. Cells of the immune system, such as natural killer (NK) cells and T cells, do not work as well following surgery. Arginine, an amino acid, is fundamental in metabolic processes of the body. Surgery has shown to cause a reduction of arginine in the body. In turn, this deficiency causes NK cell suppression. In this study, we want to look at the effects of arginine supplementation before and after surgery on NK cell function in surgery patients. In this study, we will be using a nutritional supplement containing arginine and a placebo drink (provided by Enhanced Medical Nutrition) that will be taken by colorectal cancer patients 5 days before surgery and 5 days after surgery. Using patient blood samples, we will measure NK cell levels, arginine levels and also arginase activity.

The purpose of this study is to determine the safety and tolerability of entinostat used in combination with pembrolizumab in patients with Non-small Cell Lung Cancer. Additionally, the purpose of the study is to assess how effective entinostat and pembrolizumab are in combination in patients with Non-small Cell Lung Cancer, Melanoma, and Mismatch-Repair Proficient Colorectal Cancer

To investigate whether cetuximab alone (given until progression or cumulative toxicity) after 8 cycles of FOLFIRI + cetuximab results in a non inferior Progression Free Survival when compared with continuous FOLFIRI + cetuximab (given until progression or cumulative toxicity). To assess whether an improvement in the incidence of grade 3-4 hematological and non-hematological adverse events (AEs) can be achieved in the experimental arm (cetuximab alone after 8 cycles FOLFIRI + cetuximab) as compared to the continuous chemotherapy arm (FOLFIRI plus cetuximab) To explore the possibility of using liquid biopsies for molecular profiling as well as monitoring treatment activity in mCRC pts receiving cetuximab based therapy

The goal of the Phase I portion of this study is to find the highest tolerable dose of azacitidine combined with capecitabine and oxaliplatin (CAPOX) that can be given to patients with metastatic colorectal cancer. The goal of the Phase II portion of this study is to learn if azacitidine, given in combination with CAPOX, can help to control metastatic colorectal cancer. The safety of this drug combination will also be studied.

This trial is for patients with colon cancer, head and neck cancer and lung cancer that has not responded to standard therapy. Cetuximab targets a receptor on cancer cells called the Epidermal Growth Factor Receptor or EGFR. It is thought that this receptor is turned "on" in some cancers, enabling cancer cells to divide and grow. Blocking this receptor can turn this signal off. Cetuximab blocks this receptor from the outside of cancer cells. It is thought that cancer cells can turn this signal back on by the EGFR joining with a related receptor called ErbB2. Lapatinib blocks both EGFR and ErbB2 from the inside of cancer cells. In laboratory experiments it has been found that combining drugs that target both EGFR and ErbB2 might work better in turning this signal back off. The purpose of this study is to determine the maximum dosages that patients can tolerate when these two medicines are given at the same time. In addition, in order to be on this trial, patients must agree to have a tumor biopsy before starting treatment on this study and 21 days after starting treatment. These biopsies are a required part of the study. Patients must also agree to have blood drawn for research testing to see whether genetic differences between patients explain different reactions to and side effects from, these medicines.

Eicosapentaenoic acid (EPA) is a naturally occuring omega-3 polyunsaturated fatty acid found in oily fish. EPA has anti-colorectal (bowel) cancer activity in experimental models. This trial will test whether EPA reduces markers of tumour growth, and is safe and well tolerated,in patients with colorectal cancer liver metastases awaiting surgery.

A multicentre two-part phase I/II study evaluating response and safety of SORAFENIB in combination with irinotecan in the second line treatment or more of metastatic colorectal cancer with K-RAS mutation.

This study is being done with a new therapy called "Selective Internal Radiation Therapy" (known as SIRT). Radiation is an effective treatment for destroying tumors. It is widely used in cancer treatment. However, radiation can harm normal tissue. SIR-Spheres are tiny plastic beads. They contain a radioactive agent called Yttrium-90. These beads can be delivered through a small tube inserted into the blood vessel that goes directly to the tumor. The radiation goes directly to the tumor. This spares healthy parts of your liver.
