Active clinical trials for "Colorectal Neoplasms"

This clinical trial is looking at a combination of drugs called trastuzumab and pertuzumab. This combination of drugs is approved as standard of care treatment for adult patients with metastatic breast cancer. This means it has gone through clinical trials and been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Trastuzumab and pertuzumab work in patients with these types of cancers which have a molecular alteration called HER2 amplification or HER2 activating mutation. Investigators now wish to find out if it will be useful in treating patients with other cancer types which are also HER2 amplified or HER2 mutated. If the results are positive, the study team will work with the NHS and the Cancer Drugs Fund to see if these drugs can be routinely accessed for patients in the future. This trial is part of a trial programme called DETERMINE. The programme will also look at other anti-cancer drugs in the same way, through matching the drug to rare cancer types or ones with specific mutations.

BDTX-4933-101 is a first-in-human, open-label, Phase 1 dose escalation and multiple expansion cohort study designed to evaluate the safety and antitumor activity of BDTX-4933. The study population comprises adults with recurrent advanced/metastatic cancers harboring BRAF (Class I, II, and III), KRAS (other than G12C such as G12D, G12V), or NRAS mutations including non-small cell lung cancer (NSCLC), melanoma, histiocytic neoplasms, thyroid cancer, colorectal cancer, and other solid tumor cancers with or without brain metastases. All patients will self-administer BDTX-4933 orally in 28-day cycles until disease progression, toxicity, withdrawal of consent, or termination of the study.

In this study, Chinese participants with MSI-H or dMMR advanced colorectal cancer will be assigned to receive either pembrolizumab or the Investigator's choice of 1 of 6 standard of care (SOC) chemotherapy regimens for treatment. There is no hypothesis testing for this study.

This study is a prospective single-arm phase II clinical study. Advanced gastric and colorectal tumor patients with FGFR 1-3 alterations who have failed standard therapy will be enrolled in this study once they have signed the informed consent form (ICF) and been identified as eligible in screening. The patients will receive 13.5 mg of pemigatinib once a day (QD) orally following a 2-week administration/1-week interruption regimen. They will be dosed until disease progression or intolerable toxicity. During treatment, clinical tumor imaging evaluation will be performed according to RECIST v1.1 every 6 weeks (± 7 days) and then every 9 weeks (± 7 days) after week 48. Safety will be assessed according to NCI-CTCAE 5.0.

Colorectal Cancer (CRC) is a leading cause of cancer-related death. Around 30% of patients present with advanced disease and 50% of those that attempt curative surgery will eventually relapse. The potential synergism of combining PARP inhibitor and PD-L1 is based on the hypothesis that pharmacological inhibition of PARP by olaparib will result in enhanced immunogenicity which can be further enhanced with an immune checkpoint inhibitor such as pembrolizumab. This may occur through a number of mechanisms, such as increased production of cytokines and chemokines that have the potential to promote antitumour immunity, upregulation of surface receptors which render tumour cells more visible to detection by cytotoxic T cells thereby leading to death of tumour cells and release of neoantigens, that help promote antigen presentation and immune priming. This hypothesis is supported by preclinical studies in mouse models of cancer, demonstrating that administration of a PARP inhibitor to sensitive tumour types resulted in increased T cell infiltration and immune activation within tumours. The primary hypothesis is that Olaparib and pembrolizumab combination will lead to an increase in objective response rate in patients with refractory metastatic colorectal cancer (mCRC) with DNA homologous-recombination-repair deficiency (HRD) from 1.5% in benchmark studies to up to >10%. The primary objective of the study is to determine the objective response rate (ORR) of pembrolizumab in combination with olaparib, assessed by the investigator per RECIST criteria version 1.1. Secondary objectives include efficacy in terms of disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and duration of response (DOR); safety and an exploratory study of biomarkers associated with treatment efficacy and disease prognosis.

Evaluate the clinical safety and feasibility of NKG2D CAR-T administrated by hepatic artery transfusion for patients with previously treated liver metastatic colorectal cancer.

In this open-label phase III study, patients with local advanced colon cancer (TanyN+ ,M0, dMMR/MSI-H, at least 10cm from the anus verge)will be scheduled to Group A: receive anti-PD-1 antibody alone (8 cycles, 200mg iv drip Q3W) and Group B (4 or 8 cycles of XELOX: oxaliplatin 130mg/m2 day 1, capecitabine 2000mg/m2 days 1-14, repeated every 21 days). The primary endpoint was 3 Disease-free survival; analyses were done based on all patients with post-randomization data.

The Phase 1b part of this study is conducted to assess the safety and tolerability of E7386 in combination with pembrolizumab in participants with previously treated selected solid tumors, and to determine the recommended Phase 2 dose (RP2D) of E7386 in combination with pembrolizumab. The Phase 2 part of this study is conducted to assess the objective response rate (ORR) of E7386 in combination with pembrolizumab (melanoma, colorectal cancer [CRC], hepatocellular carcinoma [HCC]) or of E7386 in combination with pembrolizumab plus lenvatinib (HCC) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

This is a two-group, parallel, randomized, standard-control phase II study comparing the safety and efficacy of trifluridine/tipiracil combined with oxaliplatin and bevacizumab versus XELOX plus bevacizumab in the first-line treatment of advanced colorectal cancer. This study was conducted in the Department of Gastrointestinal Medical Oncology, Tianjin Medical University Cancer Institute and Hospital. Patients with advanced colorectal cancer will be randomly assigned (1:1) to trifluridine/tipiracil combined with oxaliplatin and bevacizumab (experimental group) or XELOX plus bevacizumab (control group) after signing informed consent. In this study, 184 patients will be enrolled, 92 patients will receive trifluridine/tipiracil combined with oxaliplatin and bevacizumab and 92 patients will receive standard therapy. In the experimental group, the treatment regimen is trifluridine/tipiracil 35mg/m2 orally taken on d1-5 and d8-12, oxaliplatin 85mg/m2 and bevacizumab 5mg/kg intravenously infused on d1 and d15 every 4 weeks, up to 6 cycles. Then patients will be given trifluridine/tipiracil and bevacizumab maintenance treatment. Patients enrolled in this group could acquire trifluridine/tipiracil free of charge. The control group was XELOX plus bevacizumab regimen, bevacizumab 7.5mg/kg, d1 oxaliplatin 130mg/m2, d1, capecitabine 1000mg/m2, orally, bid (half an hour after breakfast and dinner), d1-14, every 3 weeks, up to 8 cycles. Then patients will be given capecitabine and bevacizumab maintenance treatment. Patients received regular and periodic reviews, with imaging evaluations every 8 weeks. Safety will be evaluated by AE and laboratory tests. All patients were followed up every 3 months until death according to the plan.

For high-risk stage II and stage III colorectal cancer, even after radical resection and postoperative adjuvant chemo/radiotherapy, 30-40% of patients will still have recurrence and metastasis. Thymosin-alpha 1 is believed to improve immunity and may help promote tumor immunity to reduce the incidence of recurrence and metastasis. This study hopes to verify the effecacy and safety of thymosin-alpha 1 for adjuvant treatment of high-risk stage II and stage III colorectal cancer after radical resection.
