Stallergenes: Staloral(R) Mites 300 Clinical Study in China: Efficacy is Demonstrated
announces the results of a phase III clinical trial (VO55.06) conducted in
(Staloral(R) mites 300) in adult patients suffering from asthma triggered by
house dust mites.
Study VO55.06 is a phase III randomized, double-blind, placebo-controlled
study conducted over a period of 15 months in 14 centers located in
main cities. After an observation period of 3 months, 484 adult patients with
mild to moderate asthma well controlled under inhaled corticosteroid therapy
were divided into two groups, one treated with Staloral(R) 300 and one given
a placebo for a period of 12 months. Throughout the duration of the study,
the patients received inhaled corticosteroid therapy at gradually reduced
dosages. The patients were assessed on the basis of the level of asthma
control as defined by GINA(1).
Staloral(R) 300 demonstrated statistically significant efficacy versus
placebo for the control of asthma, on the basis of the following criteria:
“well-controlled asthma” and “totally controlled asthma” in GINA 3 patients
(moderate asthma stabilized with corticosteroids by bronchial route). In this
population, the probability of a patient having his/her asthma well or
totally controlled is more than twice as high with Staloral(R) 300 as it is
in the placebo group (odds ratios and 95% confidence intervals of 2.10 [1.01;
4.36] and 2.43 [1.28; 4.61] respectively).
The treatment was well tolerated. There were no pulmonary side effects
related to worsening of asthma or deterioration in lung function.
“We are very pleased with the outstanding outcomes of this large-scale
study, conducted in
better asthma management and improved quality of life for patients”,
emphasizes Prof. YIN Jia, Principal Coordinator and Head of the Allergy
Department at the Peking Union Medical College Hospital and President of the
Chinese Allergology Society.
“For the first time, the efficacy of sublingual allergen immunotherapy
has been demonstrated in the stabilization of allergic asthma due to mites in
adults through a large-scale clinical trial. This very good outcome will
enable us to apply for registration of Staloral(R) mites 300 in
near future. Obviously, these results will lead the clinical development
program for Actair(R), our sublingual immunotherapy tablet for the treatment
of allergic rhinitis triggered by dust mites, to also focus on the treatment
of asthma in patients allergic to mites”, adds
CEO of Stallergenes.
ABOUT ALLERGIC ASTHMA
Asthma is a chronic inflammatory disease of the airways, very often
linked to allergic rhinitis: 80% of allergic asthma sufferers also have
allergic rhinitis and 40% of patients with untreated rhinitis go on to
Particularly common in children, asthma is a major public health problem.
The frequency of the condition varies from one country to another; in the
great majority of developed countries, between 5 and 15% of the adult
population and 3 to 7% of the pediatric population are affected. The
prevalence of asthma has been gradually increasing over the last 20 years in
industrialized countries, at a rate of around 5% per year.

populations, 2 out of 3 allergic rhinitis sufferers are consulting a
