Background: The current therapeutic strategy of applying pediatric-based regimens for acute lymphoblastic leukemia (ALL) to adults with ALL exposes these patients to multiple doses of asparaginase (ASP). Exposure to long-acting or pegylated ASP is particularly prominent due to dosing convenience, since pegylated ASP can be administered intravenously and requires fewer doses than shorter-acting forms. Previously, adult patients were much less likely to be treated with ASP-containing regimens due to reports from the 1970s of increased toxicity from ASP in adults compared with children. We report on the toxicities encountered in 3 protocols that include multiple doses of pegylated ASP as part of therapy for ALL in adult patients. Methods: Thus far, the 3 protocols have enrolled 92 patients between the ages of 14 and 71 years. The pegylated ASP dose ranges from 2000–2500 IU/m2. Approximately 330 doses of pegylated ASP have been given. Results: Grade 3–4 hepatic toxicity is the most prominent; grade 3–4 transaminase elevation occurred in 47 (51%) patients, and grade 3–4 hyperbilirubinemia was seen in 22 (24%) patients (Table). Hyperglycemia was grade 3–4 toxicity in 30 (33%) patients. Grade 3–4 allergic reactions to pegylated ASP occurred in 5 (5%) patients. Twelve (13%) patients developed thromboses. Of note, 3 (3%) patients have had leukoencephalopathy on magnetic resonance imaging scans with reversible stroke-like symptoms. The majority of hepatic toxicities resolve spontaneously, allowing patients to continue chemotherapy. All of the patients with stroke-like symptoms have fully recovered. Conclusions: Considerable hepatotoxicity and hyperglycemia occur in adult ALL patients treated with polychemotherapy that includes long-acting ASP. Other toxicities occur with a frequency similar to that seen in pediatric patients treated with a long-acting ASP. This toxicity profile warrants close monitoring and continued data collection from clinical trials that use pegylated ASP in adults with ALL.
