News Release

CHICAGO, June 06, 2019 (GLOBE NEWSWIRE) -- 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, announced today that the U.S. Food and Drug Administration (FDA) has extended the initial Prescription Drug User Fee Act (PDUFA) goal date for its review of the Company’s New Drug Application (NDA) seeking marketing approval of Gvoke™ (ready-to-use glucagon injection) by three months. The new PDUFA goal date is September 10, 2019.

The Company received a notification letter from the FDA on June 5, 2019, which states that the Company’s recent submission in response to an information request from the FDA constitutes a major amendment to the NDA, and therefore, the FDA is extending the goal date by three months to provide time for a full review of the submission. According to FDA’s current PDUFA Performance Goals, an FDA decision to extend the review period typically is limited to situations where review of the new information could address an outstanding issue(s) and lead to approval in the current review cycle. The FDA has not requested additional clinical data in connection with the Gvoke NDA, and the Company has provided all additional information that FDA has requested to date.

“We believe that we have sufficiently responded to FDA’s requests for information throughout the review, and we look forward to working with the FDA to answer any additional questions the agency may have as it completes its review of the Gvoke NDA,” commented Paul R. Edick, Chairman and Chief Executive Officer of Xeris. “Our commercial team remains focused on preparing for the potential launch of Gvoke in the fourth quarter.”

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 indications to prevent or manage various forms of hypoglycemia and improve glucose control.

About Xeris Pharmaceuticals, Inc.
Xeris is a specialty pharmaceutical company leveraging its novel technology platforms to develop and commercialize ready-to-use, room-temperature stable injectable and infusible drug formulations. The Company’s proprietary XeriSol™ and XeriJect™ formulation technologies are being evaluated for the subcutaneous (SC) and intramuscular (IM) delivery of highly-concentrated, non-aqueous, ready-to-use formulations of peptides, small molecules, proteins, and antibodies using commercially available syringes, auto-injectors, multi-dose pens, and infusion pumps. XeriSol™ and XeriJect™ have the potential to offer distinct advantages over existing formulations of marketed and development-stage products, including eliminating the need for reconstitution, enabling long-term, room-temperature stability, significantly reducing injection volume, and eliminating the requirement for intravenous (IV) infusion. These attributes may lead to products that are easier to use by patients, caregivers, and health practitioners and reduce costs for payers and the healthcare system.
