Sosei Heptares Notes New Positive Phase II Data for QVM149, a Potential Novel Inhaled Combination for Treating Asthma, Were Presented at ATS 2019

- QVM149 demonstrates significant improvements over current standard-of-care inhaled treatment for asthma

- Improvements in lung function versus placebo also established irrespective of administration time

TOKYO and LONDON, May 22, 2019 /PRNewswire/ -- Sosei Group Corporation ("the Company"; TSE: 4565) notes that its partner Novartis presented key Phase II data for QVM149, a potential new inhaled combination therapy for asthma, at the 2019 annual international congress of the American Thoracic Society (ATS) in Dallas, USA (17–22 May 2019).

QVM149 is an investigational, once-daily, fixed dose combination asthma treatment containing indacaterol acetate, glycopyrronium bromide and mometasone furoate (IND/GLY/MF), delivered with the dose-confirming Breezhaler® inhalation device. Glycopyrronium bromide and certain intellectual property relating to its use and formulation were exclusively licensed to Novartis in April 2005 by Sosei Heptares and Vectura Group PLC (LSE: VEC). Novartis is responsible for the development and commercialization of QVM149, which is currently being investigated in a Phase III clinical program expected to complete in Q3 2019.

In two Phase II clinical studies1, QVM149 was shown to be superior to the comparators, salmeterol/fluticasone propionate (the standard-of-care treatment) and placebo, separately by demonstrating improvement in lung function in patients with asthma. In one study, QVM149 also demonstrated improvements versus placebo irrespective of administration time of morning or evening. The safety data from both studies also suggest that QVM149 has a favorable safety and tolerability profile.

"These data continue to support QVM149's therapeutic benefits in patients with asthma," said Shinichi Tamura, Chairman, President and CEO of Sosei Heptares. "We look forward to results from the Phase III clinical program and further progress in the development of this novel inhaled combination therapy."

About QVM149 (IND/GLY/MF)

Indacaterol acetate, glycopyrronium bromide and mometasone furoate (IND/GLY/MF) is currently in Phase III clinical development. This formulation combines comprehensive bronchodilation of indacaterol acetate (a LABA [long-acting beta agonist]) and glycopyrronium bromide (a LAMA [long-acting muscarinic receptor antagonists]) with mometasone furoate (high- or medium-dose ICS [inhaled corticosteroid]) in a precise once-daily formulation, delivered with the dose-confirming Breezhaler® inhalation device.

About the referenced Phase II clinical studies with QVM149

CQVM149B2208 study (ClinicalTrials.gov Identifier: NCT03063086) was a Phase II, randomized, double-blind, double-dummy, active-controlled, 3-period complete cross-over study to assess the bronchodilator effect and safety of two doses of QVM149 compared to a fixed dose combination of salmeterol/fluticasone in patients with asthma.

CQVM149B2209 study (ClinicalTrials.gov Identifier: NCT03108027) was a Phase II, randomized, double-blind, repeat dose cross-over study to assess the bronchodilator effects of once daily QVM149 following morning or evening dosing for 14 Days compared to placebo in patients with asthma.
