One of the treatments generally used to treat this disease is a chemotherapy called FOLFIRI. The purpose of this study is to improve the efficacy of the chemotherapy by adding a protein, similar to immunoglobulins, aflibercept, and to assess their tolerance. Aflibercept is a protein that has already been studied in the treatment of metastatic colorectal cancers, in combination with a chemotherapy involving irinotecan in addition to 5FU (fluoropyrimidine) ( (FOLFIRI) as 2nd line treatment. It is marketed in Europe and it is authorized in the United States. Its addition to this chemotherapy combination has in fact brought about a benefit in terms of progression-free survival and overall survival. The purpose of the study is to evaluate the efficacy and tolerance of this combination rather in the initial approach to the treatment of metastatic colorectal cancers and hence to evaluate it as 1st line treatment
The AMALTHEA (Aflibercept MAintenance after first-Line THErapy with FOLFIRI+Aflibercept in metastatic colorectal cancer patients) trial is an investigator-initiated, single arm, open-label, phase II study. Patients with histologically proven metastatic colorectal carcinoma will be treated with a combination of FOLFIRI and aflibercept for 6 months. Both Kirsten rat sarcoma viral oncogene homolog (KRAS) wild type (wt) and mutant (mut) patients wil be enrolled. In the absence of Progressive Disease (PD) after 6 months of the combination of chemotherapy and aflibercept, the patient will be treated with a maintenance therapy with aflibercept alone until PD or unacceptable toxicity, investigator's decision or patient's refusal of further treatment or death, whichever comes first.
Since its introduction, 5-fluorouracil (5-FU) has been the cornerstone of treatment for metastatic colorectal cancer (mCRC). Meanwhile the oral 5FU pro-drug Capecitabine (Xeloda®) proved equivalence to 5-FU and is a well tolerated alternative combination partner for Irinotecan (XELIRI) or Oxaliplatin (XELOX) which are widely used for first line treatment of mCRC. Recent advances in molecular biology have resulted in the development of an inhibitor of the vascular endothelial growth factor (VEGF) by the monoclonal humanized antibody bevacizumab (Avastin®). XELOX or XELIRI +bevacizumab have been investigated in several trials, but not in an approach with clearly defined cross-wise XELIRI-XELOX change criteria. This trial investigates two different sequential treatment options with XELIRI/ XELOX in first and second line with the addition of bevacizumab and tries to give answer to the question if there is an optimal sequence for the benefit of the patient. This is a prospective, randomized, open-label, 2-arm pilot trial in patients with mCRC who did not receive systemic treatment for their metastatic disease. The study is designed to evaluate the efficacy of XELIRI followed by XELOX and XELOX followed by XELIRI + bevacizumab in terms of Duration of Disease Control (DDC). Patients will be treated with an established first line therapy consisting of either XELOX or XELIRI + bevacizumab. The chemotherapy treatment will be given for 6 months except prior disease progression, unacceptable toxicity or patient refusal. Bevacizumab will be given until disease progression, unacceptable toxicity or patient refusal. Capecitabine can be given in addition at the investigators' discretion until disease progression, unacceptable toxicity or patient refusal. If serious side effects occur despite adequate dose reduction, Oxaliplatin or Irinotecan should be discontinued. In case of Oxaliplatin or Irinotecan-related discontinuation Capecitabine and Bevacizumab should be continued. If Capecitabine also has to be discontinued in first line treatment bevacizumab should be continued. In case of permanent discontinuation of bevacizumab for toxicities, chemotherapy should be continued. Upon completion of first line chemotherapy patients with disease control will receive bevacizumab maintenance treatment. On investigators decision patients can receive Capecitabine as additional maintenance treatment. The primary endpoint is to determine the efficacy of a modified XELIRI + bevacizumab followed by XELOX + bevacizumab scheme at progression in comparison with the reverse sequence based on DDC. Secondary endpoints are first line progression-free survival (PFS), second line PFS, overall response rate, time to response, duration of response, overall survival, tumor assessments (based on RECIST criteria) using CT scans, MRI scans, X-ray, bone scan, clinical examination.
The metastatic colon cancer is a major public health problem despite advances in chemotherapy; few new drugs are in development for the treatment of this pathology. Many studies have shown that human colon cancer is a tumor that is recognized by the immune system and the presence of lymphocytic infiltrates in the tumor bed is associated with a better prognosis. Conversely, the effect of chemotherapy on the immune response is little studied. Recently the importance of myeloid suppressor cells (MDSC) in the development of colon cancer and the effect of 5- fluorouracil on this cell population has been highlighted. An accumulation of these cells in the blood and lymphoid organs during tumor progression is observed. Moreover, it has been established that the death of MDSC induced by 5-fluorouracil induces activation of caspase -1 and IL-1beta by these MDSC. These events promote the polarization of CD4 T cells in intratumoral Th17 lymphocytes. The IL- 17 produced by these cells exerts a pro-angiogenic effect in inducing proliferation of endothelial cells expressing and thus limits the effect of 5- fluorouracil endoglin. In humans, it has also been observed that chemotherapy using 5- fluorouracil and in particular LV5FU2 association +/- bevacizumab induces rapid death of blood MDSC as well as activation of caspase 1 in these cells. Thus, production of IL - 1 is detected in the serum of patients after 24 hours of the administration of 5-fluorouracil. Chronic inflammation and the production of interleukin- 1 can alter the effectiveness of anti -tumor immune responses and facilitate angiogenesis. Many preclinical data suggest a role of anti -tumor inhibition of IL- 1beta, but the effect of a combination of chemotherapy and an inhibitor of IL - 1beta has not yet been tested in human. Anakinra is a drug used in humans for many years to treat signs and symptoms of rheumatoid arthritis. In combination with methotrexate, in patients whose response to methotrexate alone is not satisfactory it had shown interesting results. The dose used clinically is 100 mg per day which is the dose that is proposed to be tested in this study. In this context it should be remembered that methotrexate is a chemotherapeutic agent from the class of antimetabolites such as 5- fluorouracil. RCP of this drug indicate that in studies originator toxicity was similar between the control arm and anakinra arm with an increase in serious infections (1.8 % vs 0.7 %) and an increased incidence of neutropenia (2.5 % neutropenia > grade = 1). The main toxicity observed is a painful inflammatory reaction at the injection site in 70 % of patients The investigators believe that this project could permit to validate in man preclinical observations showing an anti-tumor potential for combination anakinra and 5 fluorouracil.
This is a Phase 2, open-label, randomized, 3-arm trial investigating the efficacy of two Sym004 doses (Arm A and Arm B) compared with a control group (Arm C) in subjects with metastatic colorectal cancer (mCRC) and acquired resistance to anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (mAbs).
PURPOSE: A primary aim of phase II FOCULM study is to explore whether cetuximab in combination with FOLFOXIRI as first treatment could improve surgical conversion in patients with KRAS/NRAS wild-type, unresectable liver - only metastases of colorectal cancer. The first secondary aim is to evaluate the safety and tolerability of the chemotherapy of FOLFOXIRI plus Cetuximab targeted therapy regimen in this patient population. Secondary aims include determination of objective response rate, progression free survival, quality of life and time to recurrence for patients undergoing complete resection and/or ablation of liver.
The primary objective of this study is to evaluate whether the management of colorectal cancer (CRC) patients with 5-fluorouracil (5-FU) exposure optimization testing reduces 5-FU related toxicities and improves outcomes compared to the current standard of care. A secondary objective is to characterize the variability of 5-FU levels among CRC patients managed with 5-FU exposure optimization testing and the impact of such management on 5-FU plasma levels and drug doses during the course of chemotherapy.
This is a multicentre, open-label, Phase I/II study of enadenotucirev in patients with either solid tumour of epithelial origin not responding to standard therapy or for whom no standard treatment exists (Phase I dose escalation stage Single cycle), mCRC not responding to standard therapy (Phase I dose escalation Repeat cycle cohort expansion stage ), mCRC not responding to standard therapy or advanced or metastatic bladder cancer not candidate for chemotherapy (Phase Ib) or mCRC in stable disease or partial response after 3-4 months of first line standard of care chemotherapy (Phase II).
Regorafenib is a valuable treatment option for metastatic colorectal cancer patients who have progressed after prior standard treatments. Prior progression-free survival data suggest that there could be a distinct subgroup of patients that may benefit from regorafenib. The aim of this study is to identify predictive biomarker of regorafenib in terms of its efficacy.
