Active clinical trials for "Colorectal Neoplasms"

This phase I/II trial studies the best dose and how well trifluridine/tipiracil hydrochloride combination agent TAS-102 (TAS-102) and nanoliposomal irinotecan work in treating patients with gastrointestinal cancers that have spread to other places in the body (metastatic) or cannot be removed by surgery. Drugs used in the chemotherapy, such as trifluridine/tipiracil hydrochloride combination agent TAS-102 and nanoliposomal irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

This trial will study tisotumab vedotin to find out whether it is an effective treatment for certain solid tumors and what side effects (unwanted effects) may occur. There are seven parts to this study. In Part A, the treatment will be given to participants every 3 weeks (3-week cycles). In Part B, participants will receive tisotumab vedotin on Days 1, 8, and 15 every 4-week cycle. In Part C, participants will receive tisotumab vedotin on Days 1 and 15 of every 4-week cycle. In Part D, participants will be given treatment on Day 1 of every 3-week cycle. Participants in Part D will get tisotumab vedotin with either: Pembrolizumab or, Pembrolizumab and carboplatin, or Pembrolizumab and cisplatin In Part E, participants will receive tisotumab vedotin on Days 1 and 15 of every 4-week cycle. In Part F, participants will receive tisotumab vedotin on Days 1, 15, and 29 of every 6-week cycle. Participants in Part F will get tisotumab vedotin with pembrolizumab. In Part G, participants will receive tisotumab vedotin on Days 1, 15, and 29 of every 6-week cycle. Participants in Part G will get tisotumab vedotin with pembrolizumab and carboplatin.

Background: - Durvalumab is a drug that may help people s immune systems respond to and kill cancer cells. Olaparib is a drug that may inhibit repairing DNA damage of cancer cells. Cediranib is a drug that may stop the blood vessel growth of cancer cells. This study has two components. In the phase 1 component of the study, researchers want to investigate how well participants tolerate the combination of these drugs in treating advanced solid tumors, and in the phase 2 part of this study, researchers want to study if the combination treatments are effective in ovarian cancer. Objectives: - Phase 2 part of the study: To determine how effective this combination is in treating ovarian cancer. Eligibility: - Phase 2 part of the study: Adults age 18 or older with advanced or recurrent ovarian cancer that has no standard treatment. Design: Participants will be screened with medical history, physical exam, and blood and urine tests. They will have CT or MRI scans. For these, they will lie in a machine that takes pictures of their bodies. Phase 2 part of the study requests the participants to have tumor samples removed. Participants will get Durvalumab through an IV. A small plastic tube will be inserted into a vein. The drug will be given every 4 weeks until disease progression. Participants will take olaparib or cediranib by mouth every day. Every 28 days will be 1 cycle. For cycle 1, participants will have 2 study visits. All other cycles, they will have 1 visit. At these visits, they will repeat the screening procedures. Patients will keep a drug and diarrhea diary. Patients on cediranib will monitor their blood pressure and keep a blood pressure diary. Participants who can become pregnant, or have a partner who can become pregnant, must practice an effective form of birth control. After 12 cycles, participants will have 1-3 months of follow-up.

This phase II trial studies how well chemotherapy and/or metastasectomy work in treating patients with colorectal adenocarcinoma that has spread to the lungs (metastases). Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Metastasectomy is a surgical procedure that removes tumors formed from cells that have spread from other places in the body. It is not yet known if chemotherapy and metastasectomy together works better in treating patients with metastatic colorectal adenocarcinoma with lung metastases.

Cancer immunotherapy with immunostimulatory antibodies targeting the CTLA-4 or PD-1/PD-L1 pathways has demonstrated its efficacy in variable proportions of cancer. For metastatic colorectal cancer (mCRC) it appeared that only the small subgroup of patients with MSI-H tumors (microsatellite instability-high phenotype) had a clinically meaningful response to the anti-PD-1- L1 antibodies. In the majority group of non-MSI-H CRC (90-95% of patients), current research expect that additional means would be able to render the tumor "immunogenic" (like MSI-H CRC) and increase the intratumoral immune infiltrate which is the prerequisite to observe a benefit from PD1-PD-L1 inhibitors. Combinations of immune checkpoint inhibitors and procedures that increase intratumoral immune responses, such as targeted therapy, are actively explored.

Colorectal cancer (CRC) is one of the most common gastrointestinal tumors. According to the latest cancer report, the incidence and mortality rates of CRC are both ranked top 5 among malignant tumors worldwide and continue to rise. Patients who receive treatment in the early stage (stage I) have a 5-year survival rate of approximately 90%. However, for high-risk stage II and III colorectal cancer patients, the 5-year survival rate is only 40%-70%, and almost half of the patients experience postoperative recurrence and metastasis. Evidence suggests that Stage III CRC patients can benefit from standard adjuvant chemotherapy. It is worth noting that some high-risk stage II patients, especially those with T4N0, have a poorer prognosis compared to stage IIIA (T1-2N+). Adjuvant chemotherapy is now also recommended for postoperative cases of high-risk stage II CRC. Given the high effectiveness of the three-drug FOLFOXIRI regimen in treating metastatic CRC and the success of adjuvant chemotherapy in treating pancreatic cancer, the combination of 5-fluorouracil, oxaliplatin, and irinotecan may have a synergistic effect. Extensive study results have shown that: (a) The status of ctDNA methylation after surgery is significantly correlated with patient prognosis, and patients who are positive for ctDNA methylation in the first 1-4 weeks after surgery (before adjuvant chemotherapy) have a poor prognosis. (b) Patients who are ctDNA methylation positive in the first 1-4 weeks after surgery (before adjuvant chemotherapy) can benefit from adjuvant chemotherapy, and achieving ctDNA methylation negativity through adjuvant chemotherapy significantly improves patient prognosis. This project focuses on exploring the optimized mode of postoperative adjuvant chemotherapy for high-risk stage II and III CRC guided by ctDNA methylation, which has high scientific and innovative value. This multicenter, prospective, and randomized controlled cohort study uses a single-tube methylation-specific quantitative PCR (mqMSP) detection, which detects 10 different methylation markers and can quantitatively analyze plasma samples containing tumor DNA as low as 0.05%. This study will use this ctDNA methylation detection technology to perform quantitative detection of ctDNA methylation in the plasma of enrolled patients, and explore the effect of different chemotherapy regimens on ctDNA clearance rate and the prognostic value for ctDNA positive patients. We hope to screen out high-risk populations for recurrence through postoperative ctDNA testing, and administer more intensive chemotherapy regimens (chemotherapy upgrading) as early as possible to improve ctDNA clearance rate and patient prognosis.

This phase I/II trial studies the best dose and side effects of encorafenib, cetuximab, and nivolumab and how well they work together in treating patients with microsatellite stable, BRAFV600E gene mutated colorectal cancer that cannot be removed by surgery (unresectable) or has spread to other places in the body (metastatic). Encorafenib and cetuximab may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.Giving encorafenib, cetuximab, and nivolumab may work better in treating patients with colorectal cancer compared to cetuximab alone.

This is a multi-center, non-randomised Phase 1b study to evaluate the safety and tolerability of ATP128 alone or in combination with BI 754091 and of heterologous prime-boost ATP128 + VSV-GP128 in combination with BI 754091. ATP128 is a self-adjuvanted chimeric recombinant protein vaccine being developed in combination with programmed cell death 1 (PD-1) blockade for the treatment of microsatellite stable (MSS) patients not responding to PD-1 blockade. The PD-1 inhibitor being tested with ATP128 is the BI 754091 (Ezabenlimab) compound which belongs to the human immunoglobulin G4 (IgG4) subclass of antibodies. VSV-GP is a recombinant chimeric vesicular stomatitis virus (VSV, Indiana strain Rhabdoviridae) which carries the envelope glycoprotein (GP) of the visceral non neurotropic WE-HPI strain of the Lymphocytic choriomeningitis virus (LCMV, Arenaviridae) instead of the native VSV glycoprotein (G) and is developed as integral part of the prime-boost regimen together with ATP128. The Sponsor plans to enrol 96 patients with histologically or cytologically confirmed stage IV colorectal cancer coming form three different patient populations: Cohort 1a: 6 patients with stage IV colorectal cancer (CRC) having failed standard of care (SoC) therapies Cohorts 1b, 2a, 2c: 30 patients with stage IV microsatellite stable/mismatch repair-proficient (MSS/MMRp) CRC being in stable disease (SD) or partial response (PR) after first line of SoC (4-6 months duration at minimum) Cohorts 2b, 4b: 30 patients with stage IV MSS/MMRp liver-limited disease Patients eligible for this study will be enrolled in one of the 8 cohorts depending on their disease: Patients in Cohort 1a will receive ATP128 as single agent Patients in Cohorts 1b, 2a, 2b, 2c will receive ATP128 in combination with BI 754091 Patients in Cohorts 3, 4a, 4b will receive ATP128 and VSV-GP128 in combination with BI 754091

This study would like to assess the efficacy of pressurised intraperitoneal aerosol chemotherapy (PIPAC). This technique delivers chemotherapy directly into the abdomen via a less invasive laparoscopic or 'keyhole' form of surgery. This type of chemotherapy takes the form of an aerosol, similar to the spray of a deodorant for example. The aerosol is administered into the abdomen under pressure, pushing the chemotherapy deeper into the tissues and cancer. This approach does not involve any surgical removal of the cancer.
