Under the terms of the partnership agreement, Stallergenes Greer and Nuance Pharma will work together on the development and registration of Actair® in China. Nuance Pharma would be responsible for the subsequent commercialisation of Actair® on the Chinese market.
“We are excited by the prospects of this strategic partnership for Actair® in China. By leveraging Stallergenes Greer’s strong heritage in respiratory allergen immunotherapy (AIT) and Nuance Pharma’s provenexpertise in market access as well as their established commercial platform in China, we aim to accelerate access to Actair® for patients in need. This major step forward underscores Stallergenes Greer’s determination to provide valuable evidence-based treatment options for individuals suffering from house-dust mite allergies. It also supports our broader ambition to expand the availability of our AIT treatments across more geographies, while unlocking the full potential of Actair®,” stated Dr Andreas Amrein, CEO of Stallergenes Greer.
“Respiratory disease is among Nuance's core areas of focus, and we are actively building a franchise with innovative solutions. Actair® is a perfect fit for our portfolio and strategy, as it represents a differentiated solution to address the medical needs in allergy. We look forward to a successful partnership with Stallergenes Greer, a leader in allergy therapeutics, on Actair® and beyond, to bring innovative therapies to Chinese patients” stated Mark Lotter, CEO and founder of Nuance Pharma.
Nearly 18% of China’s population suffers from HDM-induced allergic rhinitisi. Over the past five years, the number of AIT-treated patients posted double-digit growth, driven by the rising burden of HDM-induced respiratory allergies and thus highlighting the significant treatment gap. AIT has the potential to reach €1 billion within 10 years, making it the largest AIT market in the world.
Current Chinese guidelines and expert reviews recommend AIT as a first-line treatment for allergic rhinitis, particularly in moderate to severe cases. However, uptake remains limited by infrastructure and awareness hurdles. With the introduction of Actair®, Stallergenes Greer’s HDM tablet, more patients will gain access to a convenient treatment option, addressing the needs of those living with HDM-induced allergies.
Stallergenes Greer’s SLIT tablet for HDM-induced allergic rhinitis is already commercialised in 21 countries and territories with more to follow under the brand names Actair®, Orylmyte® or Aitmyte®.
With this agreement, Stallergenes Greer continues to advance its mission of improving allergy care by making immunotherapy treatments accessible in new and high-need markets.

Forrester: Three Years Into GenAI, Enterprises Are Still Chasing Its True Transformative Value2.4.2026 16:00:00 CEST | Press Release
According to Forrester’s (Nasdaq: FORR) latest report, Accelerate Your AI Voyage, most enterprises are struggling to turn growing AI adoption and investment into measurable business impact. One of the key factors holding businesses back is low artificial intelligence quotient (AIQ) — Forrester’s measure of AI aptitude — with many employees lacking a clear understanding of how to use AI. Other barriers include an overemphasis on productivity-focused use cases, difficulty measuring impact, and siloed adoption within individual functions. While these challenges can leave firms frozen in doubt or indecision, the wait-and-see approach to AI adoption is no longer viable. To unlock AI’s full potential, organizations need to focus on four key areas: Define the business outcomes and success metrics for what they want AI to achieve; identify specific use cases for AI deployment aligned to those business outcomes; establish a structured runway to plan, test, and strategically time the deployment
