Filter by:The purpose of this study is to determine the maximum tolerated dose(MTD)/Recommended Phase 2 Dose(RP2D) and to evaluate the safety and tolerability of GC1118 when given by intravenous (IV) infusion to patients with stage IV solid tumors. The study will also evaluate pharmacokinetics, immunogenicity and antitumor effect of GC1118 and explore prognostic biomarkers and pharmacodynamic biomarkers.
BACKGROUND: For patients with liver-limited metastatic colorectal cancer (mCRC), complete resection of liver metastases is the only potentially curative treatment. The current goal of medical treatment for colorectal cancer with initially unresectable liver metastases is to maximize the rate of secondary resection and prolong overall survival (OS). A strong correlation was found between response rate and secondary resection rate of metastases, and the triple drugs combination of infusional 5-fluorouracil/leucovorin (5-FU/LV), irinotecan, and oxaliplatin (FOLFOXIRI) was recommended can be used in selected patients with potentially resectable metastases in order to improve response rate and make resection more possible. The addition of a anti-VEGFs monoclonal antibody such as bevacizumab to chemotherapy has been shown to increase response rate, resection rate and improve OS in the first-line treatment of mCRC patients. The efficacy and safety of bevacizumab in addition to triplet drugs were previously tested in OLIVIA trial, the resection rate of liver metastases of 49% was reported, and the response rate was 81%; most common grade 3-4 adverse events was neutropenia. On the basis of such promising results, we conducted the present randomized study to explore whether FOLFOXIRI plus bevacizumab compared with FOLFOXIRI alone as first-line treatment could improve radical resectability in patients with RAS mutation-type, unresectable liver-only metastatic colorectal cancer. OBJECTIVE: The primary objective of the FOBULM study is to evaluate the efficacy of FOLFOXIRI plus bevacizumab compared to FOLFOXIRI alone in patients with initially unresectable liver-limited RAS mutation-type mCRC. Secondary objectives are safety and tolerability of the treatment, efficacy in terms of objective response rate (ORR), OS, progression free survival (PFS), quality of life and an assessment of biomarkers for predictive response and prognosis.
Surgical resection is still recommended as the optional treatment for colorectal liver metastasis (CLM) patients. There are two main concerns for resectable colorectal liver metastasis which remain controversial: surgical time and surgical type. As for the former, synchronous resection of primary colorectal tumor and liver metastasis, with the reason of fare overall survival rate and absence of a second surgery, has gained wide population from gastrointestinal surgeons who believe it will bring benefits to CLM patients. With regard to surgical type, Open liver resection is the optimum choice for CLM patients no matter what the metastasis profile is. And for management of primary tumor, laparoscopic procedure is mature in surgical skill and has been evidenced equivalent overall survival rate compared with open resection. So, primary colorectal tumor resection could be either open or laparoscopic procedure. Therefore, the investigators team conducted the controlled trial to compare two surgical procedures in treatment of resectable colorectal liver metastasis. Patients will be randomly assigned into conventional laparotomy group for simultaneously resection of both primary colorectal tumor and liver metastasis, or laparoscopic-assisted small-incision group for resection of laparoscopic colorectal tumor combined with synchronously small-incision open resection of liver metastasis. The aim of this trial is to observing short-term operative effects after surgeries.
The main purpose of this research is to verify the safety of CEA targeted chimeric antigen receptor T cells and to determine the proper dosage of CAR T cells infused.
ColoCare is an international prospective cohort study of stage I-IV colorectal cancer patients (ICD-10 C18-C20).
This is a Phase I, open label study to evaluate the safety, tolerability, and immunogenicity of INO-1400 alone or in combination with INO-9012, delivered by electroporation in subjects with high risk breast, lung, or pancreatic cancer with no evidence of disease after surgery and adjuvant therapy. Subjects will be enrolled into one of six treatment arms. Subjects will be assessed according to standard of care. Restaging and imaging studies will be performed to assess disease relapse per NCCN guidelines. RECIST will be used to validate the findings in cases of relapse.
Detect plasma Hsp90α concentration of colorectal cancer patients, healthy volunteers, benign colorectal diseases patients.
Objectives: 1. Determine the surveillance practice patterns following curative resection of colorectal cancer 2. Identify patient characteristics related to eligibility for treatment after the detection of a colorectal cancer recurrence
Approximately half of colorectal cancer (CRC) patients were first diagnosed after 70 years old. However, compared with younger patients, elderly patients were often undertreated in chemotherapy due to their impaired tolerance. Recently, there have been great controversy on adjuvant chemotherapy strategy for stage II/III CRC patients. As an oral fluoropyrimidine, capecitabine has been demonstrated to be equivalent to i.v. 5-Fu/leucovorin regimen in stage III CRC patients. In light of fewer adverse effects and better flexibility, capecitabine was regarded as an ideal alternative for elderly CRC patients, but the optimal dosage for stage II/III elderly CRC patients still remains inconclusive. Our trial expected to prospectively randomized 710 postoperative stage II/III elderly CRC patients (between 70 and 90 years of age) to adjuvant mono-chemotherapy with a standard dose of capecitabine (2500 mg/m2/day) or a reduced dose (2000 mg/m2/day). This is a non-inferiority phase 3 trial with a primary endpoint of 3-year disease free survival (DFS), and other outcomes include 3-year overall survival(OS), completion rate, toxic and adverse effects and quality of life(Qol). By this trial, we aimed to achieve more precise evidence on the individualized adjuvant chemotherapy strategy for stage II/III elderly CRC patients.
Severity of colorectal cancer (CRC) is evaluated by its local staging, locoregional and general ( presence of metastases , usually liver ). This is the most common cancer in France and, despite surgical treatment of the primary tumor, it is still subject to a high mortality rate due to metastatic evolution, mainly hepatic . There is currently no specific marker for predicting cancer, the same hardly changed , which would modulate the aggressive therapeutic strategy . antigen (CEA) is used in the monitoring of JRC made.Tissue factor (TF) is the VII tissue factor receptor. it initiates the coagulation cascade. it was noted as a true cell marker tumorale1 aggressiveness. Corroborating evidence that the way the TF plays an important role in the invasive and metastatic potential of CRC. First, various human cancer cell lines express the FT colic. Furthermore, there is a relationship between the importance of monocyte TF expression and the evolutionary potential of human CRC. The investigators hypothesize that these interest intra-platelet and plasma markers are a reflection of tumor angiogenic potential. And the investigators will verify the superiority of their preoperative levels in the CRC group compared with the control group, normalization of postoperative after surgical resection rates and their possible re-ascent in case of tumor recurrence in the CRC group. The levy to one month in controls allow us to verify the absence of secondary modification to laparotomy, the colectomy and general anesthesia. The investigators assume that the rate of soluble TF in peripheral blood of the holders of CRC patients may be a marker of invasion and aggression (i.e. prognosis).
