Active clinical trials for "Colorectal Neoplasms"

The study will use previously established doses of panitumumab or cetuximab in the metastatic setting for the treatment of unresectable colorectal cancer (CRC). It is designed to investigate an alternative treatment strategy to maximize the benefit to inhibition of epidermal growth factor receptor (EGFR) for a highly selected patient population. It will enroll 110 participants with left-sided, unresectable metastatic CRC. Participants will be on study up to 5 years.

This phase Ib/II trial investigates the side effects and best dose of LY3214996 when given together with cetuximab alone or in combination with abemaciclib and to see how well they work in treating patients with colorectal cancer that cannot be removed by surgery (unresectable) and/or has spread to other places in the body (metastatic). Cetuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. LY3214996 and abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving LY3214996 and cetuximab alone or in combination with abemaciclib may help treat patients with colorectal cancer.

A study investigating if analysis of circulating tumor DNA (ctDNA) can guide adjuvant treatment in patients with advanced colorectal cancer (CRC)

The investigators have developed an innovative mobile health (mHealth) coping skills training protocol, mCOPE, that is adapted to meet the multiple symptom needs and stage-of-life challenges faced by young and middle-aged adults with cancer, and delivered in a convenient and flexible format that does not incur further demands. Young and middle-aged colorectal cancer patients who report pain, fatigue, and psychological distress will be invited to participate in the study. Participants will be randomly assigned to one of two conditions: mCOPE or standard care. mCOPE will teach patients coping skills to manage their cancer-related symptoms (pain, fatigue and distress) in the context of unique age-related challenges; session content will be tailored based on participants' report. mCOPE sessions will be delivered via videoconferencing to the patient in his/her own environment and scheduled at times that are convenient to the patient. mHealth technology, including a mobile app, will be used to capture daily symptom and coping skills use data, allowing the study team to provide personalized real-time feedback to patients. Investigators want to understand the impact of the mCOPE intervention delivered to young and middle-aged colorectal cancer patients with pain, fatigue, and distress. mCOPE is expected to lead to reduced symptom severity and improved quality of life. Study aims include: testing the efficacy of mCOPE for improving symptoms and quality of life and examining improved self-efficacy for symptom management as a mediator of symptom severity.

A phase II study to assess the efficacy and safety of Surufatinib combined with Sintilimab as a second-line treatment in patients with advanced MSS-Type CRC.

This study intends to perform high-intensity focused ultrasound combined with REGOTORI in patients with multiline drug-resistant metastatic colorectal cancer to explore the safety and efficacy of patients. Patients receive HIFU local treatment combined with REGOTORI treatment, and receive corresponding clinical data collection at different follow-up points, including necessary data from various laboratories, CT/MRI, and immune function tests that are exactly the same as before surgery collection.

The study aims to estimate the efficacy and safety of systemic therapy sequenced radical surgery in treating patients with synchronous isolated para-aortic lymph node metastasis of colorectal cancer.

This study is a prospective, randomized phase III, to evaluate if in patients with mCRC RAS/BRAF wild type on tumor tissue and RAS mutations on liquid biopsy, treating in first line with antibody anti-VEGF (bevacizumab) plus chemotherapy (FOLFIRI) is superior in terms of PFS compared to standard treatment with antibody anti-EGFR (cetuximab) plus FOLFIRI, and then in patients RAS/BRAF wild type on tumor tissue who develop RAS mutations on liquid biopsy after the beginning of the first line treatment with cetuximab plus FOLFIRI, in the absence of a clinical or radiological progression disease, to anticipate a change of treatment with bevacizumab plus FOLFIRI further impacts on the PFS.

The association of doublet chemotherapy (FOLFOX and FOLFIRI) and anti-EGFR-moAbs (panitumumab or cetuximab) is a standard option for the first-line treatment of unresectable RAS and BRAF wt mCRC patients, especially with left-sided primary tumour. In RAS wt mCRC patients refractory to chemotherapy and anti-EGFR naive, the standard treatment sequence is an anti-EGFR-based therapy (panitumumab or cetuximab +/- irinotecan) followed by regorafenib. In a phase II randomized Japanese study named REVERCE, a higher OS was reported in favour of an experimental strategy of regorafenib followed at progression by cetuximab +/- irinotecan compared with the reverse standard sequence in chemorefractory and anti-EGFR-naïve, RAS wt mCRC patients. However, the limitations of the REVERCE study (phase II trial with a premature conclusion for poor accrual) do not allow us to draw definitive conclusions. In addition, nowadays, patients candidates to an anti-EGFR-based treatment, receive anti-EGFRMoAbs in earlier lines of therapy thus affecting the translation of these results in the current clinical practice. Retrospective analyses and a phase II single-arm trial showed promising activity of anti-EGFR rechallenge in patients who previously achieved benefit from a first-line anti- EGFR-based treatment and not bearing RAS mutation on ct-DNA at the rechallenge baseline. Based on these considerations, the Investigators designed the present phase II randomized study of panitumumab followed at progression by regorafenib versus the reverse sequence in RAS and BRAF wt mCRC patients with the following characteristics: previous treatment with, or not considered candidates for, fluoropyrimidine, oxaliplatin, irinotecan and an anti-angiogenic agent (bevacizumab or aflibercept); RECIST response or stable disease lasting at least 6 months to a previous first-line anti-EGFR-based treatment; RAS and BRAF wt ct-DNA at the time of screening. The aim of this study is to compare the two sequences in a Caucasian population of patients candidates to anti-EGFR rechallenge.

Regorafenib has demonstrated a significant benefit in overall survival in metastatic colorectal cancer (mCRC) patients. However, more than 50% of patients had severe adverse events (grade 3-4), leading to temporary or definitive discontinuation of treatment. The RePERSO study proposes to adapt the regorafenib dose regimen taking into account firstly the measurement of sum of metabolites M-2 and M-5 and secondly the occurrence of toxicity during treatment. This treatment personalization through therapeutic drug monitoring pharmacological dosing optimization strategy aims at validating the proof of concept of regorafenib therapeutic drug monitoring and at improving the benefit in OS in patients, using the previously defined Csum therapeutic range.
