About GRASPA®

GRASPA^® is a new enzyme formulation of L-asparaginase with a safer and broader range of clinical uses compared to existing forms due to the entrapment and protection of the enzyme inside the homologous red blood cell. GRASPA^®’s (encapsulating L-asparaginase in red blood cells) interest lies in overcoming all existing limitations associated with conventional L-asparaginase through  longer efficacy, better compliance, reduced dosage and an increased safety profile; making it satisfactory for every ALL patients, even high risk ones (hypersensitive, elderly patients), or patients with neutralising antibodies.

L-asparaginase is a critical and irreplaceable component of combination chemotherapy for ALL and has been used in the clinic for over 30 years. The enzyme depletes the plasmatic amino acid asparagine, which leukaemia cells require to continue their rapid, malignant growth. While normal cells are able to make a sufficient amount of asparagine internally, leukaemia cells cannot. Infusion of L-asparaginase destroys the external source of asparagine, which starves leukaemia cells of this amino acid and leads to cellular death.
