This clinical trial compares minimal residual disease (MRD) testing with the Haystack blood test (assay) to the Signatera® assay for the early detection of the cancer returning (cancer recurrence) in patients with stage II-IV colorectal cancer (CRC) that can be removed by surgery (resectable). MRD testing looks for evidence of remaining tumor following treatment that is only apparent using highly sensitive techniques. There are few effective tools available outside of imaging to identify CRC patients with MRD who may be at the highest risk for cancer recurrence after surgery. Early detection of CRC recurrence after surgery is important, as it may increase the chance of curative (ability to cure) outcomes for patients with cancer recurrence. Currently, the Signatera assay is used to monitor whether CRC recurs after surgery, however it is not a very sensitive test. Early work with the Haystack assay suggests it may be more sensitive than the Signatera assay, which may be more effective for the early detection of cancer recurrence in patients with resectable stage II-IV CRC.
This is a randomized, double-blind, placebo-controlled study of B07, administered daily by subcutaneous (SC) injection, in up to 120 patients with newly diagnosed metastatic colorectal cancer. This study will evaluate different doses of B07 on weight, body composition and BMI in patients with sub-optimal BMIs (≤ 29 kg/m\^2). Treatment will start at the second cycle of first-line cancer chemotherapy and continue for 12-weeks with the goal of maintaining body weight and muscle mass in patients undergoing chemotherapy relative to control.
This phase II trial studies how well CBX-12 works in treating patients with microsatellite stable colorectal cancer that has spread to other parts of the body (metastatic) and is no longer responding to chemotherapy treatment (chemotherapy-refractory). The usual approach to treating colorectal cancer includes treatment with surgery, radiation, or Food and Drug Administration (FDA)-approved drugs such as trifluridine-tipiracil, bevacizumab, regorafenib, or fruquintinib. However, most metastatic colorectal patients progress through all approved treatments and eventually succumb to their disease. CBX-12 is a drug that contains a peptide (a substance that contains many amino acids \[molecules that join together to form proteins\]) called pHLIP, linked to an anticancer substance called exatecan. Upon administration, pHLIP gets inserted into the cellular membrane of tumor cells, delivering exatecan to kill them. Giving CBX-12 may work better than the usual approach in treating patients with metastatic chemotherapy-refractory microsatellite stable colorectal cancer.
Although implementation intentions (I2)-based tools enhance colorectal cancer (CRC) screening uptake, prior studies have not tested their implementation into routine primary care delivery. In this study, investigators will conduct a cluster-randomized trial in 20 US primary care clinics. Specific aims for the project will be: 1) to test whether a Normalization Process Theory-informed Participatory Learning in Action (NPT-PLA intervention) implementation of a proven implementation Intentions-based colorectal cancer screening tool ("I2") improves screening uptake (i.e. screening order and completion) within 6 months of patient enrollment versus usual quality improvement (control) implementation; and 2) to evaluate the facilitators and barriers of each implementation arm using the 2022 expanded Normalization Process Theory (NPT) framework. Multi-disciplinary clinic 'implementation teams' that include clinic staff and patients whose preferred language is Spanish will meet monthly during the first 6 months of clinic participation and aim to integrate into routine primary care the "I2" CRC screening tool, using the NPT-PLA intervention or control approach. The I2 tool addresses the "when," "where" and "how" details of stool sample or colonoscopy screening. The I2 tool will be delivered via an on-line survey or (if patients prefer) by paper form customized for use in English or Spanish. At least 100 patients in each clinic will be enrolled in the first 6 months of clinic participation (2000 in total). All patients eligible for CRC screening will be offered the I2 tool. Their choices will be communicated automatically to clinics for order entry. Primary (Aim 1) outcomes will be CRC screening orders placed (by clinic staff); completion of the I2 tool and CRC screening completion (by patients) over 6 months of patient follow-up. For Aim 2, surveys based on the NPT domains (the "NOMAD") will be used to assess staff comprehension of their role in implementing the I2-based CRC screening tool, its salience, their buy-in, feasibility of altering workflows, and the potential impact of using the tool in their setting. Investigators will conduct summative qualitative focus group discussions in all participating clinics after 6 months of clinic participation. The study will provide important information on barriers and facilitators of embedding NPT-PLA interventions in "real-world" primary care clinical settings.
This phase I trial tests the safety, side effects, and best dose of abemaciclib in combination with 5-fluorouracil and how well it works in treating patients with colorectal cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and that has not responded to treatment (refractory). Abemaciclib, a type of cyclin-dependent kinase inhibitor, blocks certain proteins, which may help keep tumor cells from growing. 5-fluorouracil, a type of antimetabolite, stops cells from making deoxyribonucleic acid (DNA) and may kill tumor cells. Giving abemaciclib in combination with 5-fluorouracil may be safe, tolerable, and/or effective in treating patients with metastatic and refractory colorectal cancer.
Phase 1 study to evaluate safety, tolerability and anti-tumor activity of RGT-61159 in patients with ACC or CRC
This study aims to develop a highly sensitive, specific, and cost-effective blood assay for early detection of colorectal adenomas and cancer, using advanced machine learning and state-of-the-art biological analyses.
This phase I/II trial studies the side effects and how well fluorescence image guided surgery followed by intraoperative photodynamic therapy for improving local tumor control in patients with colorectal cancer that has spread to nearby tissue or lymph nodes (locally advanced) or that has come back after a period of improvement (recurrent). Fluorescence image guided surgery uses a drug named aminolevulinic acid hydrochloride. Aminolevulinic acid hydrochloride is a photosensitizing agent, meaning that is activated by light and, is converted to another drug in cancer cells more than in normal cells. The converted drug emits fluorescence red light when activated with low power blue light. It is used to assist the surgeon to see cancer cells and small cancerous tissue that may have been missed during routine surgery. In addition to emitting fluorescence light, the converted drug in the cancer cells and tissue can be activated with red laser light to kill cancer cells. This procedure is called photodynamic therapy (PDT). Performing fluorescence image guided surgery followed by intraoperative photodynamic therapy after the surgical removal of the colorectal tumor before the surgical site will be closed may be effective and improve outcomes in patients with locally advanced or recurrent colorectal cancer.
This phase I trial tests the safety, side effects, and best dose of intraperitoneal oxaliplatin and fluorouracil in treating patients with colorectal cancer that has spread to the peritoneal cavity (peritoneal metastasis). Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill cancer cells. Fluorouracil stops cells from making DNA and it may kill cancer cells. Both oxaliplatin and fluorouracil are approved by the Food and Drug Administration to treat patients with colorectal cancer, however administration of these drugs directly into the area between the muscles and organs in the abdomen (intraperitoneal) for the treatment of peritoneal metastases is experimental. Giving oxaliplatin and fluorouracil directly into the peritoneal space may be a safe and effective way of treating patients with peritoneal metastases from colorectal cancer.
The purpose of this study is to evaluate the safety and clinical activity of cemiplimab and the combination of cemiplimab/fianlimab in microsatellite unstable localized or locally advanced colorectal cancer diagnosed in patients age 70 or greater or in patients age 18 or greater considered poor candidates for surgery.
