Active clinical trials for "Precursor Cell Lymphoblastic Leukemia-Lymphoma"

The purpose of this extension study is to provide venetoclax and obtain long-term safety data for subjects who continue to tolerate and derive benefit from receiving venetoclax in ongoing studies.

A multi-centre phase II trial of GvHD prophylaxis following unrelated donor stem cell transplantation comparing Thymoglobulin vs. Calcineurin inhibitor or Sirolimus-based post-transplant cyclophosphamide.

To gain a better understanding of the underlying dysmotility in constipation in children, we will use a novel minimal invasive method called 3D Transit. We will examine four groups of children aged 7 to 17 years: healthy children, chronically constipated children (ROM IV criteria), children with neurofibromatosis type 1 and finally children receiving chemotherapy (vincristin) for acute lymphoblastic leukemia.

Acute lymphoblastic leukemia (ALL) is the most common malignant disease among children. Treatment results have improved over time due to intensive risk-adapted therapy and the 5-year survival rate is now above 90%. However, the burden of therapy has increased proportionally. Many children develop serious acute and chronic side effects, which impact on the patients expected lifespan and impair their quality of life as a result of therapy. Treatment with PEG-asparaginase and dexamethasone increases the levels of triglycerides and total cholesterol. Consequently, the incidence of hyperlipidemia is high during initial ALL therapy. Studies have suggested that hyperlipidemia is a risk factor for development of osteonecrosis, thrombosis and possibly acute pancreatitis. Long-chained marine omega-3 fatty acids, found in fish oil, decrease levels of triglycerides and total cholesterol in hyperlipidemic patients. Due to the high survival rate, it is of great interest to develop methods to reduce treatment related toxicities. The investigators hypothesise that daily intake of fish oil will prevent development of hyperlipidemia during ALL treatment phases with dexamethasone and PEG-asparaginase compared to placebo and that fish oil intake may reduce the incidence of severe adverse events related to ALL treatment.

Childhood ALL patients are treated with high dose steroids. The study will follow the intraocular pressure of children treated in according to an AIEOP-BFM protocol, during the induction phase that will be compared to the pressure before treatment. Potential risk factors for developing elevated intraocular pressure will be estimated.

Mortality in case of SARS-CoV-2 infection (Covid-19) during acute leukemia (AL) treatment is around 30%, i.e. more than 10 times the one of general population. Severe forms are reported in children receiving chemotherapy for AL. However, the main risk, largely underestimated, is related to delay in chemotherapy administration in case of infection, leading to an increased risk of relapse. Therefore, it is justified to propose an anti-Covid-19 vaccination to these patients. Vaccination of siblings also seems necessary given the uncertainty regarding vaccine response in children with AL and given that household is the main source of contamination. The messenger ribonucleic acid (mRNA) vaccine COMIRNATY® (BNT162b2) is already approved by health authorities for individuals older than 12. In immunocompromised children with AL, safety and efficacy data are unknown. The benefit/risk balance encourages to use the vaccine without health authority approval in children aged 1 to 15 with AL. Regarding household, parents are vaccinated for several months as standard of care, but vaccination will be proposed to siblings aged 12 to 15 years old in this protocol. The primary objective of this study is to evaluate safety and immunogenicity of COMIRNATY® (BNT162b2) vaccine (two injections 21-28 days apart) in children with acute leukemia (1 to 15 years old) and their siblings (≥12-15 years old). A secondary objective of the study is to compare the quality of humoral and cellular vaccine responses in children with AL and healthy children.

This randomized clinical trial will evaluate two approaches of GvHD prophylaxis; the standard of care GVHD prophylaxis regimen (methotrexate/calcineurin inhibitors) and post-transplant cyclophosphamide with calcineurin inhibitors for their efficacy as a new GVHD prophylaxis strategy.

The purpose of this study is to evaluate the efficacy of supplementation with Omega 3, Vitamin D and Calcium, in a cohort of children with ALL undergoing treatment and compare changes in the concentrations of biomarkers of bone resorption (TRAP5b, CTX, and RANKL), the RANKL/OPG ratio, and biomarkers of bone formation (BALP, OC, PINP, PICP and OPG) after 6 and 12 weeks of supplementation.

A single-arm, non-randomized four-month trial of the adapted family-based behavioral weight loss treatment (FBT) intervention will be conducted to evaluate its acceptability, feasibility, and preliminary indications of efficacy including measures of relative weight change and associated secondary outcomes (e.g., weight related health behaviors, health related quality of life), among 40 childhood acute lymphoblastic leukemia (ALL) survivors and their families.

CiproPAL is a randomised trial comparing daily ciprofloxacin with local standard care during the induction phase of paediatric ALL treatment, and aims: To assess the efficacy of ciprofloxacin prophylaxis in the reduction of infection during the induction phase of treatment for paediatric Acute Lymphoblastic Leukaemia within the ALLTogether-1 Trial. To evaluate the impact of ciprofloxacin prophylaxis on antimicrobial resistance, both of invasive infections and colonising organisms.
