Asparaginase-based drugs are highly successful (up to 97%) against childhood acute lymphoblastic leukaemia (ALL), however, they occasionally induce a serious side effect Acute pancreatitis (AP) that often forces to discontinue the treatment. AP is a potentially deadly disease with no specific therapy in the clinic. Previous investigations into the mechanisms of AP (recently reviewed in Petersen et al 2021) established that intracellular ATP loss is a crucial factor exacerbating calcium overload and necrosis. We have recently reported that glucose metabolism and hence ATP production are severely inhibited under AP conditions. Severe ATP loss and calcium overload potentiate each other leading to massive necrosis. We have suggested supplementing glucose with galactose and found both significant and substantial reductions of all crucial hallmarks of asparaginase-induced AP in vitro and in vivo. Conclusion & Significance: Galactose as an oral supplement effectively protects pancreas in different models, including asparaginase-induced mouse model of AP. Galactose supplementation has been shown also to increase ATP levels in control cells, suggesting that its use is not limited to AP cases. Available data suggest that galactose oral supplementation can be used to reduce side effects of asparaginase-based drugs for ALL and potentially other cancer drugs where ATP loss and necrosis limit their therapeutic potential.
