About this trial
Acute lymphoblastic leukemia (ALL) is the most common cancer seen in pediatric oncology. The necessary chemotherapy for pediatric and adolescent and young adult (AYA) patients with ALL includes steroids, anthracyclines, asparaginase, and vincristine. One of the most hepatotoxic chemotherapy agents is asparaginase, with treatment-associated hepatotoxicity (TAH) observed in up to 60% of patients. The frequency of TAH is increased in overweight or obese patients of Latino heritage. Carnitine is a naturally-derived compound that is produced in the liver and kidneys; it is found in certain foods, such as meat, poultry, fish, and some dairy products. Endogenous carnitine transports long-chain fatty acids into the mitochondria, where they are oxidized to produce energy, and acts as scavengers of oxygen free radicals. Thus, carnitine can reduce oxidative stress and modulate inflammatory response. Levocarnitine is a supplement form of carnitine used typically in the care and management of patients with carnitine deficiency. Pediatric and AYAs with ALL will be given oral levocarnitine as a supplement during their initial phases of treatment, when the most hepatotoxic agents are administered, to determine if the incidence of liver toxicity can be reduced or eliminated.

Treatment groups
Trial outcomes
Primary outcomes
Primary Outcome #1
Calculate proportion of patients who experience hepatotoxicity, as measured by the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 grade ≥ 3 elevated alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total and direct bilirubin.
Primary Outcome #2
Calculate prevalence of hepatotoxicity in patients who self-identify as Latino or non-Latino, using laboratory assessments and self-reported measures of ethnicity and/or race.
Secondary outcomes
Secondary Outcome #1
Calculate body mass index (BMI), from recorded height and weight obtained at time of initial diagnosis and determine if there is increased risk of hepatotoxicity in patients who are overweight or obese at diagnosis as determined by Centers for Disease Control and Prevention (CDC) clinical growth charts for study participants 5 to \< 20 years of age and by a BMI of ≥ 25.0 for study participants 20 to \< 30 years of age.
Secondary Outcome #2
Quantify disease response, using end of Induction minimal residual disease (MRD) results, where an MRD value \< 0.01 is considered "negative."
Secondary Outcome #3
Calculate incidence of nonalcoholic fatty liver disease (NAFLD), using ultrasound elastography, in pediatric and AYA patients newly diagnosed with ALL.
Secondary Outcome #4
Calculate proportion of patients who experience other known toxicities of asparaginase treatment, as measured by CTCAE version 5.0 grade ≥ 3 hyper/hypoglycemia, hypertriglyceridemia, pancreatitis, and thrombosis.
