Active clinical trials for "Colorectal Neoplasms"

This is a single arm, open phase II study to evaluate the efficacy and safety of tislelizumab combined with cetuximab + irinotecan in the treatment of Ras wild-type recurrent and refractory colorectal cancer. This study will include Ras wild-type colorectal cancer that failed at least second-line treatment in the past, including chemotherapy (oxaliplatin, irinotecan, fluorouracil) with or without targeted drugs (cetuximab, bevacizumab). 33 patients were planned to be treated with tislelizumab combined with cetuximab + irinotecan every 2 weeks. The enrollment time is expected to be 12 months and the follow-up is 24 months.

The goal of this study is to improve use of colorectal cancer screening among screening eligible African Americans who are served by Federally Qualified Health Centers in Michigan. The main questions it aims to answer are: To what extent to individual prefer and select to complete screening with colonoscopy versus stool-based (FIT Kit or sDNA) options? Can full completion of (i.e. follow-through with) screening with a selected modality be enhanced by delivery of a culturally targeted intervention? Participants will learn about colonoscopy, FIT Kit and sDNA as recommended and widely used screening options. They will select a modality to complete their own screening with. Participants will then be randomized to one of three arms (usual care, standard intervention, culturally targeted intervention). Researchers will compare the extent to which intervention arms enhance completion rates across each of the three screening modalities.

In this study, MMRd metastatic colorectal cancer (mCRC) patients who failed standard therapies will undergo treatment with pembrolizumab, while RAS-extended mutated MMR-proficient mCRC patients will be tested for o6-methylguanine-DNA-methyltransferase (MGMT) expression (IHC) and then for MGMT promoter methylation. MGMT IHC-negative, promoter methylation positive patients will be treated with temozolomide (TMZ). Patients progressing under temozolomide will be tested for tumor mutational burden (TMB) and proceed to pembrolizumab if TMB is > 20 mutations/Mb. The primary study hypothesis is that tumors with acquired resistance to temozolomide become hypermutated and are sensitive to pembrolizumab.

This phase I trial studies the side effects and best dose of romidepsin in treating patients with lymphoma, chronic lymphocytic leukemia, or solid tumors with liver dysfunction. Romidepsin may stop the growth of cancer cells by entering the cancer cells and by blocking the activity of proteins that are important for the cancer's growth and survival.

The purpose of this study is to assess if panitumumab is active enough to warrant comparative studies in patients with metastatic colorectal cancer that has progressed after treatment with cetuximab.

Objectives: In this Radboud University Nijmegen Medical Centre (RUNMC) initiated study our first objective is to investigate toxicity (safety and feasibility) of vaccination with frameshift-derived neoantigen-loaded DC of CRC patients with an MSI-positive CRC and persons who are known to be carrier of a germline MMR-gene mutation with no signs of disease yet. The secondary objectives of the study are: to demonstrate that peptide-loaded DC can induce or enhance an immune response to tumor-associated antigen CEA and specific frameshift-derived neoantigens in the study population. to study the pathological and clinical responses, e.g. disease-free survival, determined according to the standard protocol. Study design: This study is a phase I/II open-label study. Study population: Two groups of adults will be vaccinated: Group I) CRC patients, who are known to carry a germline MMR-gene mutation and patients with an MSI-positive CRC and yet unknown or negative MMR-gene mutation status. Group II) persons who are known to be carrier of a germline MMR-gene mutation with no signs of disease yet. All participants need to be HLA-A2.1 positive.

This is a non-randomized study, open label phase II study. The purpose of this study is to evaluate disease control rate (DCR) by RECIST and iRECIST at 12 weeks. Evaluation of RECIST and iRECIST will be done in each center in order to choose the optimal therapy (Assessment by Investigators). A centralized evaluation of RECIST and iRECIST, will be organized in Saint-Antoine.

The main purpose of this study is to test the safety, tolerable side effects, and determine the highest tolerable dose of the combination of Regorafenib and Nivolumab. Researchers want to find out if this combination of Regorafenib and Nivolumab can help people with metastatic colorectal cancer with mismatch repair (MMR) proficiency.

This trial studies how well the drug tucatinib works when given with trastuzumab and when given by itself. The participants in this trial have HER2-positive (HER2+) metastatic colorectal cancer (mCRC). 'Metastatic' means that the cancer has spread to other parts of the body. In the first part of this study, participants enrolled into Cohort A and received both tucatinib and trastuzumab. In the second part of this study, participants are randomly assigned to either Cohort B or Cohort C. Participants in Cohort B will receive tucatinib and trastuzumab. Participants in Cohort C will receive tucatinib. Participants in Cohort C who do not respond to therapy may have an option to receive tucatinib plus trastuzumab.

An open-label, single-arm, phase II, multicentre clinical trial to determine the rate of durable clinical benefit of nivolumab in patients with class II expressing microsatellite stable colorectal cancer.
