What the trial was testing
The MT-12 enrolled 1,460 patients with allergic rhinitis. The study was sponsored by ALK-Abelló and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
22% relative reduction in combined symptom score on the dust mite tablet.
The Lancet Regional Health - Europe · 2025 · NCT04145219
These findings — that in combined rhinitis symptoms on the dust mite tablet vs. inactive tablet — were published in the The Lancet Regional Health - Europe and represent the headline result of the study.
Researchers tracked outcomes across 1,460 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with allergic rhinitis, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
House dust mite sublingual tablets (Odactra) are FDA-approved for adults but the pediatric indication is still under review in the U.S. as of early 2026. The tablet is approved in many other countries for children. Ask an allergist about access or oral allergy drops as alternatives.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.
Open allergic rhinitis trials
Study of Yupingfeng Powder Treating Allergic Rhinitis (AR)
Rhinitis is broadly defined as inflammation of the nasal mucosa. It is a common disorder that affects up to 40% of the population. Allergic rhinitis (AR) is the most common type of chronic rhinitis, affecting 10-20% of the population, and evidence suggests that the prevalence of the disorder is increasing. AR is a very common clinical disease that can occur at any age. Severe allergic rhinitis has been associated with significant impairments in quality of life, sleep and work performance. Nowadays, the main treatment for allergic rhinitis is the use of western medicine, such as steroids and antihistamines. However, many clinical studies have found that the curative effect of western medicine is often not ideal. From the perspective of Chinese medicine, this disease is resulted from the deficiency of Qi and Yang Qi in the lungs, spleen and kidneys. Therefore, according to Chinese medicine theory, tonifying lung and spleen qi is the treatment principle for AR patients. Among different Chinese herbal formulae for AR, Yupingfeng Powder is commonly used for allergic diseases and in AR patients, due to its warm nature and able to improve the functions of the lungs and spleen. Yupingfeng Powder can improve symptoms and quality of life, as well as decrease the levels of interleukin and IgE in AR patients. This study will use Yupingfeng Powder with variation to evaluate its effectiveness and safety in treating AR. Hence, a double-blind, randomized, placebo-controlled clinical trial design with strong scientific rigor will be employed in this study, and it would be able to provide robust clinical evidence on the efficacy and safety of Yupingfeng Powder with variation for AR. Recruited subjects will be randomly assigned to receive orally Yupingfeng Powder with variation or placebo twice a day for 8 weeks, with follow-up for another 8 weeks after stopping the treatment to observe the duration of efficacy. In our previous study, it is shown that Yupingfeng Powder can significantly improve the symptoms of AR, and there was no serious adverse event reported by the subjects. And in this project, we modify the design of the trial to further investigate the efficacy of Yupingfeng Powder with variation for AR patients with a larger sample size.
EmoTIChealth: Promoting Adolescent Health Through a Serious Game.
The intervention program targets adolescents between 12 and 16 years of age. The intervention program is designed for adolescents during a critical developmental stage marked by significant life transitions, where building strong personal resources and receiving psychological support is essential to foster socioemotional skills and overall well-being. The serious game aims to promote psycho-emotional health in the general adolescent population, supporting healthy development and preventing future emotional difficulties. At the same time, it incorporates specific modules for adolescents living with chronic conditions such as asthma, food allergy, type 1 diabetes, and allergic rhinitis, who may face additional risks of psychological challenges that can complicate treatment and prognosis. By combining universal health promotion with tailored support, the program addresses both the needs of healthy adolescents and those with chronic illnesses. The platform integrates digital and technological tools for dynamic and personalized intervention. Artificial intelligence adapts activities and feedback to each participant's socio-demographic profile and evolving needs, this supports directly in participants' daily lives and natural environments, making the experience more relevant and impactful. The serious game, proven effective in engaging young people, goes beyond traditional psychoeducation by creating an interactive environment where adolescents develop socio-emotional competencies, resilience, and health-related knowledge. Through its six thematic areas, the game promotes overall well-being and healthy habits, while its condition-specific modules provide targeted guidance and coping strategies for asthma, food allergies, type 1 diabetes, and allergic rhinitis.
