Concomitant drugs may explain PEG-ASP liver toxicities in ALL

REPORTING FROM EHA CONGRESS
“Notably, none of the patients undergoing full pediatric induction, which contains higher cumulative doses of PEG-ASP, experienced grade 4 hepatotoxicity regardless of age,” Dr. Guolo and his colleagues wrote in their poster presentation.
In multivariate analysis controlling for age, BMI, drug regimen, and concomitant therapies, idarubicin remained a significant risk factor for severe hepatotoxicity (P = .004), and vancomycin remained as a borderline risk (P = .054).
Dr. Guolo acknowledged that the investigators could not account for the potential contribution of over-the-counter medications with known risk for hepatotoxicity, such as acetaminophen.
He noted that in his group’s experience, the toxicity profile of PEG-ASP in adults, including high-dose regimens, was manageable without excess toxicities as long as clinicians paid close attention to the use of concomitant agents.
The study was internally funded. The authors reported having no relevant conflicts of interest.
