NCT00678145 ↗ Mechanisms of Hypoglycemia Associated Autonomic Failure Active, not recruiting National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Phase 2 2008-03-01 Intensive glucose control in type 1 diabetes mellitus (T1DM) is associated with clear health benefits (1). However, despite development of insulin analogs, pump/multi-dose treatment and continuous glucose monitoring, maintaining near-normal glycemia remains an elusive goal for most patients, in large part owing to the risk of hypoglycemia. T1DM patients are susceptible to hypoglycemia due to defective counterregulatory responses (CR) characterized by: 1) deficient glucagon release during impending/early hypoglycemia; 2) additional hypoglycemia-associated autonomic failure (HAAF) and exercise-associated autonomic failure (EAAF) that blunt the sympathoadrenal responses to hypoglycemia following repeated episodes of hypoglycemia or exercise as well as degrading other CR; and 3) hypoglycemia unawareness (HU), lowering the threshold for symptoms that trigger behavioral responses (e.g. eating). Thus, the risk of hypoglycemia in T1DM impedes ideal insulin treatment and leads to defaulting to suboptimal glycemic control (2). There are two approaches that could resolve this important clinical problem: 1) perfection of glucose sensing and insulin and glucagon delivery approaches (bioengineered or cell-based) that mimic normal islet function and precisely regulate glucose continuously, or 2) a drug to enhance or normalize the pattern of CR to hypoglycemia. Despite much research and important advances in the field, neither islet transplantation nor biosensor devices have emerged as viable long-term solutions for the majority of patients (3, 4). Over the past several years, our lab has explored the approach of enhancing CR by examining mechanisms responsible for HAAF/EAAF and searching for potential pharmacological methods to modulate the CR to hypoglycemia (5-11). Our work has led to a paradigm shift in the field of hypoglycemia, exemplified by the novel hypothesis and published experimental data supporting a role for opioid signaling that resulted in the initiation of exploratory clinical trials by other research groups.
