Stallergenes Greer announces completion of enrollment in largest phase III study to treat house dust mites allergy

LONDON--(BUSINESS WIRE)-- Regulatory News:

Stallergenes Greer (Paris:STAGR), a biopharmaceutical company specialising in treatments for respiratory allergies, announced today that it completed enrollment in a pivotal Phase III clinical study to evaluate the safety and efficacy of its investigational sublingual immunotherapy tablet STG320 for the treatment of house dust mite (HDM) induced allergic rhinitis. The study recruited over 1,600 patients from 13 countries with 231 participating investigative sites, and is the largest study of its kind. Principal investigators are Pascal Demoly, MD, from University Hospital of Montpellier, France, and the President of the French Allergy Federation, and Thomas Casale, MD, Professor of Medicine and Pediatrics at the University of South Florida.

“This is the largest study undertaken to measure the efficacy of sublingual immunotherapy (SLIT) treatment against HDM-induced allergic rhinitis and this study has the potential to bring more options for patients,” said Professor Casale. “In the United States, subcutaneous immunotherapy treatment for patients with allergic rhinitis is administered through injections at the doctor’s office; the tablet formulation offers an effective alternative treatment option for patients that may prefer oral administration at home.”

“Our aim is to bring innovation to patients suffering from HDM-induced allergic rhinitis, one of the most prevalent allergies in the world⁴. Completion of patient enrollment in this pivotal study is a significant milestone for Stallergenes Greer towards achieving this goal,” said Fereydoun Firouz, CEO of Stallergenes Greer. “We are committed to our purpose – to enable people with allergies to live normal lives – and continue to focus on developing evidence based solutions to prevent and treat all allergies.”

This Phase III study, together with other clinical data, will form the company’s submission for a Biologics License Application (BLA) in the United States planned for 2019 and for additional marketing authorizations in European and international markets. To date, the product is already approved for commercialisation in Japan, Australia and South Korea.

ABOUT THE STG320 STUDY
The study is global, multi-center, randomized, double-blind and placebo controlled. It evaluates the safety and efficacy of STG320 at a daily dose of 300IR administered to adult and adolescent patients aged 12-65 with HDM-induced allergic rhinitis. Patients who experienced HDM-associated allergic rhinitis for at least one year, who are sensitized to D. pteronyssinus and/or D. farinae mites as defined on a skin prick test and HDM-specific serum immunoglobulin E, were eligible for participation.

ABOUT HOUSE-DUST MITE INDUCED ALLERGIC RHINITIS
Allergic rhinitis is a worldwide disease affecting over 500 million people and the risk of developing asthma is about six times higher in patients with allergy to House Dust Mites (HDM) than those allergic to pollens^1-4. Allergic rhinitis can include symptoms such as sneezing, runny nose, wheezing, cough, itching, and watery/itchy eyes, among others^1,2. Symptoms may be severe and significantly impact the patient’s quality of life, as well as worsen over time with progression towards asthma^1-3,5-8.

Symptomatic treatments such as antihistamines and nasal corticosteroids provide only temporary relief to patients^1,8. The primary therapeutic goals of allergy immunotherapy (AIT) include reducing symptoms, reducing symptomatic medication use, and improving allergy-related quality of life. The evidence is strong that AIT achieves these goals and can alter the course of the disease, with benefits persisting in many patients for several years after treatment discontinuation^1,2,10-16.
