Filter by:This phase I trial studies the side effects and best dose of cabozantinib S-malate in treating younger patients with solid tumors that have come back or no longer respond to treatment. Cabozantinib S-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Background: Hepatitis C recurrence, which invariably occurs in viremic liver transplant (LT) recipients, associated with accelerated liver fibrosis leading to established graft cirrhosis in 40-20% of patients in 5 years with another 5% experiencing an aggressive form with cirrhosis and graft loss in 1 year. Since treatment after LT has a low efficacy, the overall survival of HCV-infected LT recipients is shorter than that of uninfected LT patients. New immunosuppressive agents such as mTOR inhibitors (Everolimus/Sirolimus) reduce the risk of liver graft rejection, have antifibrotic properties and do not worsen HCV recurrence. Moreover new directly-acting antiviral agents have increased efficacy of interferon-based treatment but their use in LT recipients may be limited by side effects. Hypothesis: Use of individualized immunosuppressive regimen and early personalized anti-viral treatment based on recipient and viral factors would improve outcome of HCV infected liver transplant recipients. Objectives: 1. To evaluate safety and efficacy of two steroid-free immunosuppressive regimens to reduce hepatitis C recurrence associated to fibrosis progression (F≥2 under ISHAK score) at one year post-transplant. 2. To identify viral and recipient factors associated with liver fibrosis progression using ultra-deep pyrosequencing (UDPS).
The purpose of this study is to determine the efficacy and the safety of the association of carboplatine and liposomal doxorubicin in patient with ovarian cancer in relapse, sensitive to platin.
Prostate cancer is the most commonly diagnosed cancer in men in Canada. Over 30% of men over the age of fifty have histological evidence of prostate cancer on biopsy. Despite the stage migration afforded by early detection with serum prostate specific antigen (PSA) testing and an apparent trend toward improved survival over the past several years, prostate cancer remains a significant cause of morbidity and mortality. Biochemical failure after primary therapy (surgery or radiation) remains a significant health care burden and strategies to delay clinical prostate cancer progression and prolong the interval from treatment failure to systemic therapy would be of significant clinical benefit for those men suffering from a finding of PSA recurrence. PSA is widely accepted as the most useful prognostic marker of prostate cancer progression, particularly after primary therapy with radical surgery or radiation. 5 Despite improved cancer control rates with definitive management of early stage prostate cancer, a PSA recurrence is unfortunately a common occurrence (25-50%) in most large case series. Microenvironmental factors have been demonstrated to play a pivotal role in the selection of neoplastic cell subpopulations expressing more malignant phenotypes and contributing to the progression of localized and metastatic disease. Very low levels of O2 (< 10 mmHg) has been well described in many solid tumours (including prostate cancer) and the extent of hypoxia has been demonstrated to represent an independent marker of a poor prognosis for patients with various types of cancers. Tumour hypoxia contributes to numerous adaptive phenotypes including increased invasion and metastasis, as well as evasion of immune cell surveillance increased resistance to radiotherapy and chemotherapy. Although cellular adaptive responses to hypoxia are likely mediated by various mechanisms, our previous preclinical studies suggest that decreased nitric oxide (NO)-dependent signalling plays a significant role in this progression of a malignant phenotype.
The overall objective of this protocol is to improve the cure rate of relapsed precursor B-cell acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma. This phase II trial is studying risk-directed therapy for B-lymphoblastic leukemia or lymphoma in first relapse. Standard risk (SR) and high risk (HR) participants will receive different therapy. Treatment will consist of chemotherapy for SR participants, and chemotherapy followed by hematopoietic stem cell transplant (HSCT) for HR in first relapse. Induction therapy consists of three blocks of chemotherapy. The first block is a novel immunotherapy regimen that includes chemotherapy, rituximab and infusion of haploidentical natural killer (NK) cells. SR participants will continue to receive chemotherapy for a total duration of approximately 2 years. HR participants will be candidates for HSCT and will proceed to transplant once a suitable donor is found and their minimal residual disease (MRD) is negative.
A double-blind, multicentre, stratified by centre, randomised, parallel study with two groups of adult patients operated on for Crohn's disease, to determine if oral ingestion of probiotics could prevent the appearance of Crohn's disease recurrent endoscopic ileo-colonic lesions 12 months after surgery. Patients will consume 900 mg/day of active product (N=56) or control product (N=56) during one year.
The objectives of this Phase I/II study are: 1. To find out the maximum tolerated dose (MTD) of PG2 in patients with advanced malignancy receiving chemotherapy and to define a "Study Dose" for Phase II. 2. To evaluate the hematopoietic and immunological responses after administering of PG2. Primarily to study the biological response of PG2, defined as WBC count in this study, and secondarily to study the immunological factors, IL-2, IL-6, TGF-beta, and G-CSF.
This phase II trial studies how well ipilimumab works in treating patients with human papilloma virus (HPV)-related cervical cancer that has come back or that has spread to other areas of the body. Monoclonal antibodies, such as ipilimumab, can find tumor cells and help kill them or carry tumor-killing substances to them.
The folate receptor is overexpressed in many types of cancer, including ovarian and endometrial cancer, and the level of folate receptor expression increases with the stage of the disease. Technetium Tc 99m EC20 (99mTc-EC20; FolateScan), a folate-targeted diagnostic radiopharmaceutical, is designed to bind to the folate receptor. Thus, FolateScan may provide an effective method to determine folate receptor-positive (FR+) target tumors, thereby assisting in the identification of those patients who may benefit from folate-targeted therapy.
The folate receptor is over-expressed on many types of cancer cells and new folate receptor targeted therapies are being developed to target cancer cells that over-express the folate receptor. As with other targeted therapies, it is important to develop diagnostic tests that will provide accurate information on folate receptor status and aid in selecting patients that may benefit from folate-targeted therapy.
