Filter by:This trial is a pilot, Phase 2, sequential two-cohort study designed to test two de-escalated whole brain radiation therapy (WBRT) dose levels and assess their ability to maintain acceptable in-brain distant control. The WBRT dose would decrease as the study moves forward, both in terms of absolute value and equivalent dose in 2 Gray fractions (EQD2) (as determined by the linear quadratic radiobiological model). The absolute value of the simultaneous integrated boost (SIB) dose will change with each dose level because the number of fractions delivered will depend on the WBRT dose. As such, the SIB dose will be manipulated such that the EQD2 will remain essentially equivalent despite the difference in the number of fractions delivered. This design will ensure that the only variable is the change in WBRT dose. The concept is that WBRT with SIB would be expected to maximize both local and in-brain distant control as has already been shown in studies exploring WBRT with SRS boost. However, by itself WBRT with SIB does not address the concern over neurocognitive outcomes. Therefore, investigators hypothesize that there is a lower WBRT dose threshold that will maintain acceptable in-brain distant control, particularly in the setting of a SIB to gross lesions to maintain treated lesion control. In addition, lower overall brain dose (including lower hippocampal dose without specific hippocampal avoidance) may potentially improve neurocognitive function. Investigators are also interested in evaluating treated lesion control, overall survival, neurocognitive sequelae of therapy, quality of life, performance status, and adverse effects of therapy. Biomarker identification for potential correlative circulating tumor DNA and microRNA is an exploratory endpoint to generate data for future prospective evaluation.
To provide treatment guidelines for patients with long bone metastatic disease based on observational study and to propose an algorithm to guide orthopedic surgeons in decision-making for these patient.
According to American Heart Association criteria, patients who have had Rheumatic Fever (RF) should be treated with antibiotic prophylaxis. Continuous prophylaxis is recommended in patients with well-documented histories of RF and in those with evidence of rheumatic heart disease. There is a limited data regarding adherence of patients to treatment and efficacy of treatment. In this study, patients with RF who are older than 21 years will be collected from a computerized database of 'Maccabi Healthcare Services', one of the biggest Israeli Health Funds. Patients will be assigned to the study after obtaining informed consent. Previous adherence to antibiotic prophylaxis will be examined according to computerized database of drugs which were issued to the patient since RF diagnosis. Past history of cardiac involvement, including past Echocardiograms, will be collected from computerized database. In addition, the current cardiac state will be assessed by an experienced cardiologist, including a full new Echocardiogram examination.
This is an observational, prospective (study following participants forward in time), multi-center (study conducted in more than 1 center) study to identify the risk factors, then develop and validate the predictive Nomogram of metastatic castration-resistant prostate cancer (mCRPC) that will effectively predict the early onset mCRPC in patients receiving androgen-deprivation therapy (ADT). The entire duration of study will be approximately 3 year. Participants will primarily be evaluated for achieving biochemical or radiological progression after receiving ADT based on EAU 2017 practice guideline criteria. Serum testosterone, prostate specific antigen (PSA), alkaline phosphatase (ALP) and blood routine will be monitored throughout the study.
This is a pilot study designed to evaluate the cutaneous effect of systemic inhibition of the tyrosine kinase pathway in the presence or absence of solar simulated light exposure. A maximum of 45 subjects will be accrued into the overall study we anticipate approximately 25 patients in the Raf inhibitor group and 10 patients each into the Tyrosine Kinase and MEK inhibitor arms of the study.
The proposed study will evaluate if "curative intent" SBRT can provide high response rates and clinically meaningful cancer control with acceptable toxicity specifically in patient with metastatic colorectal cancer (mCRC) who do not have surgical options and are no longer responding to systemic therapy
This is a multicentre, open labeled, single arm study to determine effectiveness and safety of chemoembolization with Irinotecan-Eluting Bead(DEBIRI) in the treatment of unresectable liver metastases in patients with colorectal cancer after chemotherapy failure.
This phase II-III study will be randomized (2:1) patients starting first-line oral targeted therapies (OTT) for metastatic cancer between an individualized supervised physical exercise programs (SPEP) by a personal coach, and recommended physical exercises via a booklet. Eligible patients will have received ≤2 lines of metastatic chemotherapy, Eastern Cooperative Oncology Group Performance status (ECOG PS) ≤2, controlled pain (visual analogue scale (VAS) <3/10), and life expectancy ≥3 months.
The main objective of the dose-escalation parts of the trial is to determine the maximum tolerated dose (MTD), based on the frequency of patients experiencing dose-limiting toxicities (DLTs), and/or the recommended dose for further development of BI 891065 monotherapy as well as of BI 891065 in combination with BI 754091, and to evaluate its safety and tolerability by monitoring the occurrence and severity of adverse events (AEs). Secondary objectives are the determination of the pharmacokinetic (PK) profile of BI 891065 monotherapy as well as of BI 891065 in combination with BI 754091, and the preliminary assessment of anti-tumour activity.
To compare 2 different image creation/processing techniques during a standard CT scan in order to "see" problems in the liver and learn which method provides better image quality. The techniques use new artificial intelligence software to decrease image noise, which helps the radiologist to evaluate.
