* Development of an ELISA to detect circulating anti-asparaginase antibodies in dogs with lymphoid neoplasia treated with Escherichia coli l-asparaginase.

- Resistance to Escherichia coli l-asparaginase in canine lymphoma occurs frequently with repeated administration, a phenomenon often attributed, without substantiation, to the induction of neutralizing antibodies. To test the hypothesis that treated dogs develop antibodies against the drug, we created an enzyme-linked immunosorbent assay (ELISA) to measure plasma anti-asparaginase immunoglobulin G responses. Using samples from dogs that had received multiple doses, specific reactivity against l-asparaginase was demonstrated, while naïve patients' samples were negative. The optimized ELISA appeared sensitive, with endpoint titers >1 600 000 in positive control dogs. Intra- and inter-assay coefficients of variation were 3.6 and 14.5%. The assay was supported by the observation that ELISA-positive plasma could immunoprecipitate asparaginase activity. When clinical patients were evaluated, 3/10 dogs developed titers after a single injection; with repeated administration, 4/7 dogs were positive. l-asparaginase antibodies showed reduced binding to the PEGylated drug formulation. The ELISA should prove useful in investigating the potential correlation of antibody responses with resistance.
