Study of Ponatinib (Iclusig) for Prevention of Relapse After Allogeneic Stem Cell Transplantation (Allo-SCT) in FLT3-ITD AML Patients

PONALLO
Start date: December 2, 2019
Phase: Phase 2
Study type: Interventional

Recent advances in acute myeloid leukemia (AML) have been characterized by a better understanding of disease biology. As such, FMS-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) have been recognized as conferring a poor prognosis. The FLT3-ITD molecular mutation is observed in about one-quarter of patients diagnosed with AML. Patients presenting with this abnormality are referred for early allogeneic stem-cell transplantation (allo-SCT). However, some data suggest that FLT3-ITD remains associated with a poor prognosis even after allo-SCT because of higher risk of relapse and strategies for preventing relapse in the post-transplant setting are required (Hu et al, Expert Rev Hematol, 2014). For example, in a large cohort of patients (Brunet et al, JCO, 2012), the incidence of relapse for FLT3-ITD AML patients after allo-SCT was 30% at 2-years, significantly higher compared to FLT3-ITD negative patients (p=0.006). Ponatinib (Iclusig®) is an orally available, tyrosine kinase inhibitor with a unique binding mechanism allowing inhibition of BCR-ABL kinases, including those with the T315I point mutation. Ponatinib also has in vitro inhibitory activity against a discrete set of kinases implicated in the pathogenesis of other hematologic malignancies, including FLT3, KIT, fibroblast growth factor receptor 1 (FGFR1), and platelet derived growth factor receptor α (PDGFRα). In vitro activity of ponatinib in AML has been already demonstrated (Gozgit et al, Mol Cancer Ther, 2011; Smith et al, Blood 2013). If some trials are on-going to test ponatinib alone or in combination with chemotherapy in FLT3-ITD AML (Clinical.trials.gov), no study is dedicated to the use of ponatinib in the post-transplant setting in order to prevent relapse in these patients. The main goal of this study will be to determine the maximal tolerated dose (MDT) of ponatinib after allo-SCT in FLT3-ITD AML patients, then to investigate the efficacy of ponatinib in a larger cohort of patients

NCT ID: NCT03689231 Active, not recruiting - Clinical trials for Neuroendocrine Tumors

Volumetric Imaging Follow up of Patients With Liver Metastases of Small Intestinal Neuroendocrine Tumors (NETs).

VOLUNET
Start date: March 1, 2018
Phase:
Study type: Observational

More than 50% of intestinal NETs are metastatic at the time of diagnosis, the liver being the main affected organ in 50-90% of cases. Initial liver tumor burden and slope of the tumor growth rate are two major prognostic factors in patients with intestinal NETs, followed by tumor grade at pathology. They are used in routine practice by oncologists to adapt patient treatment. Unlike other tumors, most NETs metastases are slow-growing tumors. Previous studies have shown that approximately half of the patients diagnosed with liver metastases showed no progression over a period of 3 to 6 months. The aim of this non randomised retrospective cohort study is to investigate whether the volumetric monitoring of the total tumor burden compared to the RECIST 1.1 criteria (used in routine practice by radiologists) at baseline and early follow-up (3 to 6 months) is more suitable for NETs, making possible to predict the prognosis at the onset of the disease, and also allowing a better adaptation of the treatment. The secondary objectives are to evaluate if the initial volume of the liver tumor is a prognostic factor of time to progression, to correlate the initial liver tumor volume and the number of liver lesions to the blood concentration of Chromogranin A (CgA), the presence of extra-abdominal disease and to correlate the tumor growth rate (TGR) and KI 67 (%) at base-line.

NCT ID: NCT03684083 Active, not recruiting - Clinical trials for Stem Cell Transplantation

Inflammatory Response to Paramyxovirus Infection in an Ex-vivo Model of Bronchial Epithelial Cells in Allogeneic HSCT Recipients

ALLOVIRO
Start date: November 1, 2018
Phase:
Study type: Observational

Introduction. Chronic graft-versus-host-disease (GVHD) is the main late noninfectious complication after allogeneic hematopoietic stem cell transplantation (HSCT) that can affect several organs. Bronchiolitis obliterans syndrome (BOS) is recognized as pulmonary chronic GVHD. A diagnosis of a lower respiratory tract infection in the first 100 days following transplant has been associated to the development of BOS. One hypothesis is that the first stage driving to BOS is a previous aggression of bronchial epithelial cells by various factors such as chemotherapy and radiotherapy. Thereafter, data suggest that viral infections, in particular Parainfluenza viruses could be a trigger for BOS. The alloimmune reaction activated by the respiratory virus could lead to the fibrosis process. Our hypothesis is that the bronchial epithelium of allogeneic HSCT recipients has phenotypic specificities that are associated with a specific response to the viral respiratory infections (in particular paramyxovirus) leading to the development of BOS. Main objective. To characterize and compare the inflammatory response after infection with Parainfluenza 3 virus in an ex-vivo model of bronchial epithelial cells obtained from allogeneic HSCT recipients and controls. Objective secondary. To characterize the phenotypic specificities of allogeneic HSCT recipients' bronchial epithelium. Methodology, and experimental plan. Prospective, monocentric research. Bronchial biopsies obtained from patients, will be completely differentiated after 21 days of culture. Epithelial cells will be infected by the virus strain Parainfluenza 3. Transcriptome of the cells from both allogeneic HSCT patients and controls, infected and non-infected will be analyzed 48 hours after infection.

NCT ID: NCT03681938 Active, not recruiting - Lymphoma, B-Cell Clinical Trials

Indication to Transplant Patients With High Risk B Cells Lymphoma in Metabolic Complete Remission?

Start date: July 3, 2017
Phase:
Study type: Observational

The autograft of patients with prognostically unfavourable B-cells lymphoma cells in first remission remains controversial, in particular since the association of Rituximab with chemotherapy. Even though many randomized and non-randomized studies have been conducted, their is still no standard procedure . Recently, the use of early TEP (positron emission topography) answer, after 2 in 3 cures of chemotherapy allowed to select the poor-responder patients who remain candidate to autograft in front-line. Nevertheless, in good-responder patients, the benefits of an intensification therapy ins term of long-lasting disease control remains discussion. This institutional retrospective study aims at comparing the outcome of early metabolic responder patients who received an intensification treatment to those who received a standard chemotherapy.

NCT ID: NCT03679572 Active, not recruiting - Renal Cancer Clinical Trials

NCT ID: NCT03676998 Active, not recruiting - Clinical trials for Prolonged Mechanical Ventilation

Diaphragm Dysfunction During Prolonged Mechanical Ventilation

DD-SRPR
Start date: February 22, 2019
Phase: N/A
Study type: Interventional

The transition to unassisted breathing after invasive ventilation often proves challenging. Persistent ventilator dependence predisposes patients to nosocomial complications and death and increases the economic burden of critical illness. Ventilator-dependence results from an imbalance between the load and capacity of the respiratory muscle pump. Patients who fail a trial of spontaneous breathing commonly exhibit excess respiratory loads secondary to weaning-induced pulmonary edema, atelectasis or dynamic hyperinflation. At the same time, many ventilator-dependent patients exhibit striking loss of respiratory pump capacity due to diaphragm dysfunction which predisposes to prolonged ventilator dependence. Diaphragm dysfunction is common in ventilated patients. By prolonging ventilator dependence it may be an important contributor to the poor long-term clinical and functional outcomes of survivors of critical illness. While some main risk factors for diaphragm dysfunction have been already described (diaphragm disuse induced by mechanical ventilation, sepsis, initial severity upon admission), the determinants of recovery of diaphragm dysfunction are unknown, as well it has not been elucidated whether diaphragm function can simply improve after the acute phase of ICU admission. Therefore, the goal of this study is to investigate the time course evolution of diaphragm function in patients exposed to prolonged duration of mechanical ventilation (i.e. in a weaning center) and to determine which factors are associated with an improvement of the diaphragm function leading to a safe mechanical ventilation discontinuation.

Survival Endpoints for Treatment Evaluation in Subjects Treated for Metastatic Breast Cancer: Contribution of Real-life Databases

Start date: September 1, 2017
Phase:
Study type: Observational

Overall survival (OS) is considered the most reliable cancer endpoint and used by the Health Rregulatory authorities (HRA). OS presents multiple advantages in cancer randomized controlled trials (RCT): it is universally accepted as a measure of clinical benefit for the patient; it is objectively defined, both in terms of events and date of incidence; it is easily and precisely measured and thus reproducible; it can be exhaustively collected. As such, OS has been validated by HRAs. On the other hand, OS presents some limitations. Observing a benefit on OS may require a large number of patients and/or considerable time for patient follow-up. Costs for trials may be increased, and there might be delays in the introduction of possible beneficial treatments for patients. The development of alternative endpoints that could capture treatment benefit appropriately and be measurable earlier, is central for the evolution of clinical research in oncology. Real world data (RWD) are defined as other sources than clinical trials such as: electronic medical records, registries, insurance claims, pharmacy records, death certificates and other patient-generated data. This research is aimed at (i) describing the existing endpoints of survival in real-life setting, (ii) comparing the correlation at individual level with data to clinical trials for related to anti-HER2 targeted therapies and endocrine therapies in MBC. We will investigate the individual correlation between candidate surrogate endpoints and overall survival in a population-based record-computerized database centralizing data on about 20,000 patients from 2008 to 2017 in France. This work should lead to the estimation of various time-to event endpoints (e.g. OS, PFS, etc), in the real-life setting, for mBC patients. In addition, we will estimate their individual correlation with OS, which should help us highlight potential surrogate endpoints in this setting. We will focuss on three distinct population, accounting for a large population of mBS patients: : patients treated with anti-HER2 targeted agents, patients treated with endocrine therapies and elderly population.

Efficacy Endpoints to Assess Treatment Efficacy in Randomized Controlled Trials in Elderly Cancer Patients

DATECANelderly
Start date: September 1, 2017
Phase:
Study type: Observational

Context and hypothesis: In cancer randomized controlled trials (RCT), the validated and most objective criterion to assess treatment efficacy is overall survival (OS). In the elderly population, OS presents limitations as it can be affected by factors other than treatment such as comorbidity or severe toxicity. Although mortality reduction is important for patients of all ages, alternative outcomes such as the ability to live independently or with a better quality of life, may be more important for older patients. Reviews of RCT have highlighted (i) the heterogeneity of such alternative efficacy outcomes and (ii) an absence of standardized definitions for these endpoints. As a result, this may limit the quality of RCT as well as the comparison of results across trials. Our objective is to provide guidelines for standardized definitions of such alternative endpoints to assess treatment efficacy in cancer RCT in elderly populations. The development of guidelines will follow a formal consensus method (questionnaires + in-person meetings). A large panel of international experts will participate. Guidelines are awaited due to the heterogeneity of endpoints and absence of standardized definitions. Standardizing definitions will improve the quality and design of future trials and enhance comparison between trials.
