Asparaginase is a drug which is given at the same time as chemotherapy drugs. It is an enzyme which deprives leukaemia cells of essential nutrients so that they die.
Three children Alejandro Gutierrez, MD, treated for leukemia during his fellowship at Boston Children's Hospital still haunt him more than a decade later.
Cancer cells are, in some respects, impressive: They can grow relentlessly, sidestep the aging process by becoming immortal, and evade the immune system's persistent attacks. But in the process of acquiring such superpowers, the cells must occasionally relinquish other, more mundane skills--including the ability to produce certain nutrients.
Researchers from Cambridge have come up with a new study that shows that some foods may influence the spread of certain cancers. Asparagine for example is a nutrient present in asparagus. If this nutrient is absent, the growth of breast cancer can be slowed, they note. The results of the study are published in the latest issue of the journal Nature.
Scientists have discovered that an amino acid called asparagine is essential for breast cancer spread, and by restricting it, cancer cells stopped invading other parts of the body in mice, according to research part-funded by Cancer Research UK and published in the journal Nature today, (Wednesday).
Researchers from RUDN University and Institute of Biomedical Chemistry of the Russian Academy of Sciences have identified an alternative mechanism for the effective antitumor drug -- an enzyme called L-asparaginase.
ERYTECH Pharma, a French clinical-stage biopharmaceutical company developing innovative therapies for rare forms of cancer and orphan diseases, today announced that it has entered into a research collaboration with Queen's University in Canada to advance the preclinical development of ERYTECH's eryminase program specifically for the treatment of arginase-1 deficiency, a rare and severe metabolic disorder related to arginine metabolism.
An enzyme identified in Saccharomyces cerevisiae, commonly known as brewer's or baker's yeast, has passed in vitro trials, demonstrating its capacity to kill acute lymphoblastic leukemia (ALL) cells.
Researchers have identified a rare genetic variation associated with a dramatically increased risk of severe acute pancreatitis in acute lymphoblastic leukemia (ALL) patients treated with the chemotherapy agent asparaginase. St. Jude Children's Research Hospital led the study, which appears today in the Journal of Clinical Oncology.
Blood-contacting implantable medical devices, such as stents, heart valves, ventricular assist devices, and extracorporeal support systems, as well as vascular grafts and access catheters, are used worldwide to improve patients' lives. However, these devices are prone to failure due to the body's responses at the blood-material interface; clots can form and inflammatory reactions can prevent the device from performing as indicated. Currently, when this occurs, the only solution is to replace the device.
Using a pediatric chemotherapy regimen to treat young adults with acute lymphoblastic leukemia (ALL) significantly improved their outcomes compared to what has historically been achieved with 'adult' treatment protocols, report Dana-Farber Cancer Institute scientists.
Phase III trial results support the use of intravenously administered PEGylated Escherichia coli asparaginase as the preparation of choice in children and adolescents with acute lymphoblastic leukaemia.
Jazz Pharmaceuticals plc announced today that the first patients have been enrolled in a Phase 3 clinical development program evaluating the safety and efficacy of its investigational drug candidate, JZP-110, as a wake-promoting agent in the treatment of excessive daytime sleepiness (EDS) in adult patients with narcolepsy or with obstructive sleep apnea (OSA).
A patent application for a drug that could destroy the deadly childhood disease known as acute lymphoblastic leukemia — and potentially other cancers as well — has been submitted by researchers at Sandia National Laboratories, the University of Maryland and the MD Anderson Cancer Center in Houston.
Jazz Pharmaceuticals plc announced today that researchers will present data on the use of defibrotide, an investigational medicine being studied in the United States (U.S.) for the treatment of hepatic veno-occlusive disease (VOD), a rare, potentially life-threatening, early complication in patients undergoing hematopoietic stem-cell transplantation (HSCT) therapy.
Jazz Pharmaceuticals plc today announced that the U.S. Food and Drug Administration approved the intravenous administration of Erwinaze (asparaginase Erwinia chrysanthemi). Erwinaze is indicated as a component of a multi-agent chemotherapeutic regimen for the treatment of patients with acute lymphoblastic leukemia (ALL) who have developed hypersensitivity to E. coli-derived asparaginase.
An enzyme that usually triggers strong allergic reactions now circulates in the veins of a group of mice without alerting the immune system. As INRS Énergie Matériaux Télécommunications Research Centre Professor Marc A. Gauthier explains in an article published in the journal Nature Communications, a polymer was used to camouflage the enzyme before it was injected into the rodents. This was achieved by coating the enzyme to avoid an immune response in a manner that does not compromise its activity.
Jazz Pharmaceuticals plc today announced that Jazz Investments I Limited, its wholly-owned subsidiary, priced its previously announced offering of $500 million aggregate principal amount of exchangeable senior notes due 2021.
Sigma Tau Pharma Ltd. (hereinafter referred to as Sigma-Tau Rare Disease), today announced the submission of an application to the European Medicines Agency for use of its pegylatedL-asparaginase, Oncaspar (pegaspargase) for the treatment of Acute Lymphoblastic Leukaemia (ALL) as part of a multi-agent chemotherapeutic regimen.
Jazz Pharmaceuticals plc today presented data from the Phase 2b study evaluating JZP-110 (formerly known as ADX-N05) as a potential new treatment for the symptoms of excessive daytime sleepiness (EDS) in adults with narcolepsy.
ERYTECH Pharma, a French biopharmaceutical company that develops innovative treatments for acute leukemia and other oncology indications with unmet medical needs, announces that the ANSM, French healthcare agency, has granted the authorization to start a Phase II study in second line treatment of patients affected by pancreatic cancer.
