He was urinating constantly, and no amount of water could abate his thirst. A blood test revealed glucose levels that were through the roof.

Eventually, researchers involved in the project hope to discover new therapeutic strategies for preventing diabetic complications without sacrificing any of the cancer-destroying potential of livesaving immunotherapy drugs.
