Overview

Hamsyl Junior is a pediatric-specific formulation of pegaspargase, a covalent conjugate of Escherichia coli-derived L-asparaginase with monomethoxypolyethylene glycol (mPEG). Developed by Gennova Biopharmaceuticals, it is used as a component of a multi-agent chemotherapeutic regimen for the treatment of pediatric patients with acute lymphoblastic leukemia (ALL). The drug functions by depleting systemic levels of the amino acid asparagine; while normal cells can synthesize asparagine, leukemic lymphoblasts lack asparagine synthetase and depend on exogenous sources for protein synthesis, leading to selective apoptosis of cancer cells. Launched in India in March 2024, this formulation provides a 1500 IU pack size (750 IU/mL) specifically designed to reduce drug wastage and ensure appropriate dosing for children's smaller body sizes.
