Active clinical trials for "Colorectal Neoplasms"

This study will assess the safety and efficacy of LGX818 when combined with cetuximab or combined with cetuximab and BYL719 in patients with BRAF mutant metastatic colorectal cancer

The purpose of this study is to find out whether it is better to receive a new drug, BBI608, or better to receive no further treatment for colon or rectal cancer. To do this, half of the patients in this study will get BBI608 and the other half will receive a placebo (a substance that is designed not to do anything).

The purpose of this study is to test a new drug combination consisting of two drugs, vemurafenib (also known as ZelborafTM) and panitumumab (also known as VectibixTM). This treatment is being tested in a subgroup of patients with colorectal cancer whose tumors have changes in the BRAF gene that may make them more likely to respond to this new drug combination.

The purpose of this study is to determine if participants with metastatic colorectal cancer live longer without their cancer progressing when treated with standard chemotherapy, standard chemotherapy plus ramucirumab, or standard chemotherapy plus icrucumab.

A new approach to treating solid tumours (both operable and inoperable) has been carried out by the Cork Cancer Research Centre (CCRC) at the Mercy University Hospital, Cork, Ireland since 2002. The approach simply allows a greater concentration of chemotherapy drugs to enter the tumour cells rather than healthy cells. The uptake of the chemotherapeutic drug directly by the tumour is aided through applying short electric pulses to the tumor mass (referred to as - Electrochemotherapy or ECT). The pulses make the tumour more porous which allows the drug easier access into the cancer cells, whereas other tissues and organs in the body remain relatively poor at absorbing the drug, thereby reducing the potential side effects on healthy tissues. This approach to date has been limited to skin based tumours due to the requirement for the electrodes to be placed directly in contact with the tumour. Procedures with electrochemotherapy have been applied to human patients in other countries of the EU, the US and Japan. The drug concentration used is significantly reduced due to the more targeted absorption by the tumor and this significantly reduces side effects normally associated with chemotherapy. A large number of preclinical and clinical Phase I and I/II studies have demonstrated the efficiency and safety of ECT. These studies have included patients with melanoma, head and neck squamous cell carcinoma, merkel cell carcinomas, basal cell carcinoma and adenocarcinoma nodules. Case reports concerning other primary tumours have also been reported. The investigators have developed an endoscopic approach (EndoVe system) for delivering the electric pulses to internal cancers and are currently seeking to evaluate its efficacy in the treatment of inoperable colorectal cancer. The treatment procedure is similar to standard endoscopic colorectal examination (colonoscopy) with the added element of an intravenous injection of bleomycin followed after eight minutes by the delivery of electric pulses (each one less than 1msec in duration). The pulses are endoscopically delivered directly to the tumour mass. The entire procedure is minimally invasive and does not require intensive care follow up or stitches. If the treatment is successful the tumour will shrink in size in the weeks following the procedure. The objective of this study is to investigate the efficacy and safety of this approach in reducing the size of the tumour.

This Phase II study is open to patients with metastatic colorectal cancer who have tried but failed chemotherapy regimens containing oxaliplatin and irinotecan. Patients must not have received anti-EGFR (Epidermal Growth Factor Receptor) treatment (for example, cetuximab, panitumumab) in the past. Patients with wild-type KRAS (v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog) colorectal cancer will be randomised to receive either BIBW 2992 or cetuximab. Patients with KRAS mutated colorectal cancer will not be randomised, but will all receive BIBW 2992. The main objectives of the study are: to compare the effectiveness of BIBW 2992 with that of cetuximab in patients with KRAS wild type cancer, and to assess the effectiveness of BIBW 2992 in patients with KRAS mutated cancer.

This study will evaluate the efficacy and safety of a first-line regimen of Avastin and Xelox (Xeloda + Eloxatin) followed by Avastin and Tarceva, in patients with metastatic colorectal cancer. Patients will receive 6 x 21 day cycles of treatment with Avastin (7.5mg/kg iv on day 1), Xeloda (1000mg/m2 po twice daily on days 1 to 14) and Eloxatin (130mg/m2 iv on day 1). Patients free of disease progression will then continue with Avastin (7.5mg/kg iv once every 3 weeks) and Tarceva (150mg po daily). The anticipated time on study treatment is until disease progression, and the target sample size is <100 individuals.

This randomized, open-label, two-way crossover study will evaluate the relative bioavailabilty and safety of capecitabine rapid disintegrating tablets (RDT) versus commercial Xeloda tablets in patients with colorectal or breast cancer. Patients will be randomized to a sequence of single oral doses of capecitabine RDT or Xeloda on Days 1 and 2 of a 14-day treatment cycle with Xeloda. Follow-up will be 30 days.

The present study aims to investigate the efficacy and safety of the combination of capecitabine and gemcitabine in heavily pre-treated, treatment resistant metastatic colorectal cancer.

The main objective is to compare resection rates (R0 or R1) for hepatic metastases in the experimental arm (tri chemotherapy plus targeted therapy) versus the control arm (bi chemotherapy plus targeted therapy); in both arms the targeted therapy is selected according to K-Ras status of the patient's tumor. The secondary objectives are to evaluate the objective response rate (CR and PR) after 4 cycles of treatment, according the RECIST V1.1 evaluation scale. the rate of complete remission (CR) at 6 months after the last study treatment (hepatic surgery or last chemotherapy cycle). the specific rates of resection R0, R1, R2. the complete pathological response Rate, the relapse-free survival rate in (R0 or R1) resected patients, the response duration in non-resected patients, the toxicity according to CTC AE V4 scale except for the neurotoxicity that will be evaluated with the Levi scale, the post operative complications using the DINDO classification, the progression-free survival (PFS) and overall survival (OS). The objectives of the biological study are: to evaluate tumor-related predictive factors such as somatic mutations (KRAS, BRAF, TP53) and genetic amplification related factors (EGFR), to evaluate patient-related predictive factors in connection with genetic polymorphisms (Fc gamma and VEGF receptors), to evaluate ADCC activity via immunohistochemistry in order to analyze the lympho free and progression-free survival, to study circulating of tumor cells as prognostic factor for metastatic colorectal cancer, non- resectable at presentation.
