Xeris to develop an ultra-concentrated, ready-to-use, subcutaneous injection of teprotumumab
Xeris Biopharma Holdings, Inc. (Nasdaq: XERS), a growth-oriented biopharmaceutical company committed to improving patient lives by developing and commercializing innovative products across a range of therapies, today announced that it has entered into a research collaboration and option agreement with Horizon Therapeutics plc (Nasdaq: HZNP). Under the terms of the agreement, Xeris will use its proprietary formulation technology platform, XeriJect™, to develop an ultra-concentrated, ready-to-use, subcutaneous injection of teprotumumab and Horizon will have an option to license the Xeris technology. Teprotumumab is the first and only medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment of Thyroid Eye Disease (TED) – a serious, progressive and potentially vision-threatening rare autoimmune disease. Teprotumumab-trbw is known as TEPEZZA® in the United States. Xeris will receive an upfront payment, and may be entitled to receive development milestones, regulatory milestones, and sales-based milestones, as well as royalties based on future sales if the commercial license option is exercised. Specific financial terms of the agreement were not disclosed.
“We are excited to announce our collaboration with Horizon for the development of a subcutaneous formulation of teprotumumab using our XeriJect technology to potentially enhance the patient experience and delivery of the treatment for Thyroid Eye Disease,” said Paul R. Edick, Chairman and CEO of Xeris. “This partnership demonstrates the potential value of our technology to enable large molecule subcutaneous injections that provide a more patient friendly regimen that is effective, safe, and more convenient, with potential for improved adherence.”
XeriJect formulations are innovative, ready-to-use, viscoelastic pharmaceutical suspensions that have the potential to improve drug delivery, lower treatment burden and improve patients' lives across a broad range of therapeutic categories. XeriJect suspensions maximize drug loadings at >400mg/mL, enable small volume subcutaneous injections and do not settle on storage. The suspensions use FDA-approved excipients and leverage known manufacturing processes. XeriJect formulation technology is well suited for drugs and biologics including large molecules such as proteins, monoclonal antibodies, and vaccines. The technology is protected by an extensive patent estate, trade secrets and know-how, and it is available for licensing.

IMPORTANT SAFETY INFORMATION
Warnings and Precautions
Infusion Reactions: TEPEZZA may cause infusion reactions. Infusion reactions have been reported in approximately 4% of patients treated with TEPEZZA. Reported infusion reactions have usually been mild or moderate in severity. Signs and symptoms may include transient increases in blood pressure, feeling hot, tachycardia, dyspnea, headache and muscular pain. Infusion reactions may occur during an infusion or within 1.5 hours after an infusion. In patients who experience an infusion reaction, consideration should be given to premedicating with an antihistamine, antipyretic, or corticosteroid and/or administering all subsequent infusions at a slower infusion rate.
Preexisting Inflammatory Bowel Disease: TEPEZZA may cause an exacerbation of preexisting inflammatory bowel disease (IBD). Monitor patients with IBD for flare of disease. If IBD exacerbation is suspected, consider discontinuation of TEPEZZA.
Hyperglycemia: Increased blood glucose or hyperglycemia may occur in patients treated with TEPEZZA. In clinical trials, 10% of patients (two-thirds of whom had preexisting diabetes or impaired glucose tolerance) experienced hyperglycemia. Hyperglycemic events should be managed with medications for glycemic control, if necessary. Monitor patients for elevated blood glucose and symptoms of hyperglycemia while on treatment with TEPEZZA. Patients with preexisting diabetes should be under appropriate glycemic control before receiving TEPEZZA.
The most common adverse reactions (incidence ≥5% and greater than placebo) are muscle spasm, nausea, alopecia, diarrhea, fatigue, hyperglycemia, hearing impairment, dysgeusia, headache, dry skin, and menstrual disorders.
