CHICAGO--(BUSINESS WIRE)--Xeris Pharmaceuticals, Inc. (Nasdaq: XERS), a specialty pharmaceutical company leveraging its novel technology platforms to develop and commercialize ready-to-use injectable and infusible drug formulations, today announced positive topline results from the in-clinic stage of a Phase 2 study of its developmental ready-to-use (RTU) glucagon in patients who experience postprandial hypoglycemic episodes following bariatric surgery.

This is a Phase 2 prospective, randomized, placebo-controlled, double-blind study that comprises an in-clinic stage followed by a 12-week outpatient stage. Subjects are randomly assigned to receive RTU glucagon or placebo during two separate meal challenges in an in-clinic stage crossover design, and then enter a parallel design outpatient stage where they are assigned to an investigational product for 12 weeks. In this study, subjects self-administer a mini dose (300 g) of RTU glucagon or placebo when they experience hypoglycemia symptoms (e.g., anxiety, nausea, sweating, tremors, palpitations), and blood glucose response is measured after the study drug is self-administered. In situations where hypoglycemia (blood glucose 70 mg/dl) is present at mini-dosing or continues after treatment, oral glucose tabs are used in addition to the study drug. The in-clinic stage is now complete, and this study is currently ongoing in the outpatient stage, where both subjects and investigators remain blinded.

Results from the in-clinic stage of this Phase 2 study demonstrate that most subjects experienced postprandial hypoglycemia within 90-120 minutes after finishing the meal. Of patients with a successful meal challenge, all subjects were also able to self-administer a mini dose of study drug, as directed, during the setting of declining blood glucose. A mini dose of RTU glucagon was adequate to restore or maintain normal blood glucose levels within 15 minutes of administration. This effect was maintained at 30 minutes, and hyperglycemia was not observed. The incidence of a follow-on episode of hypoglycemia (rebound hypoglycemia) requiring oral glucose for rescue was less with RTU glucagon compared to placebo. Treatment emergent adverse events with a mini dose of RTU glucagon were comparable to placebo, including negligible injection site reactions. Mini doses of RTU glucagon appear safe and well tolerated, and no serious adverse events occurred.

We are encouraged by the results of the in-clinic stage of our PBH study. The first half of this study is an important first step in demonstrating the utility of liquid, stable, ready-to-use glucagon in conditions beyond rescue for severe hypoglycemia and demonstrating safety and effectiveness in situations that require self-administration by the patient, said Paul R. Edick, Xeris Chairman and CEO. We believe the second half of the study, which is outside of the controlled in-clinic environment, will go further in establishing the safety profile of mini dosing RTU glucagon. That additional data will be available in the first half of 2020.

About Post-Bariatric Hypoglycemia (PBH)

Approximately 200,000 weight loss (bariatric) surgeries are performed annually in the United States. Hypoglycemia that occurs after bariatric and other forms of upper gastrointestinal surgery is a condition called post-bariatric hypoglycemia (PBH). It usually occurs >6 months to 8 years after surgery and is an uncommon and rarely reported metabolic complication that can be severe and disabling for some patients. Hypoglycemia episodes from PBH occur 1-3 hours after meals (postprandial hypoglycemia), often at a frequency of >10 times per month. Persistent or unrecognized hypoglycemia from PBH can progress to severe hypoglycemia (blood glucose <54 mg/dL) with symptoms such as loss of consciousness, seizures, coma, and even death. When postprandial hypoglycemia episodes in PBH occur, they can be difficult to acutely treat with oral carbohydrates alone, because an overcompensation with oral carbohydrates can frequently trigger a subsequent hypoglycemia episode (rebound hypoglycemia).

About Glucagon

Glucagon is a metabolic hormone secreted by the pancreas that raises blood glucose levels by causing the liver to rapidly convert glycogen (the stored form of glucose) into glucose, which is then released into the bloodstream. Glucagon and insulin are two critical hormones in a glycemic control system that keep blood glucose at the right level in healthy individuals. In people with diabetes who are dependent on insulin, this control system is disrupted, and insulin must be injected to avoid high levels of blood glucose (hyperglycemia). The opposite effect, or low blood glucose (hypoglycemia), is also prevalent in this population due to dysregulated glucagon secretion. Severe hypoglycemia is a serious condition and can lead to seizures, coma, potential brain injury and, if untreated, death.

Glucagon is the standard of care for treating severe hypoglycemia. According to the American Diabetes Association, glucagon should be prescribed for all individuals at increased risk of clinically significant hypoglycemia, defined as blood glucose <54 mg/dL (3.0 mmol/L). Leveraging XeriSol, one of Xeris two proprietary formulation technology platforms, Xeris has the potential to provide the first ready-to-use, room-temperature stable liquid glucagon for use by people with diabetes and other conditions to prevent or manage various forms of hypoglycemia and improve glucose control.
