Welcome to the 4th Annual Conference on Soft Mist Inhalers (SMIs)

SMI.London 2026
will take place on
Wednesday 10 June 2026
at the
Royal College of General Practitioners
30 Euston Square
London

This year we will focus on innovations from academia and early phase research. As we prepare the programme for the day, we invite academic researchers engaged in SMI R&D to send in their ideas for oral and poster presentations during the event. We would be pleased to consider them and help the academic community contribute fully to the SMI field. Send us an email with your ideas at info@smi.london to ask for an invitation.

Soft mist inhalers now represent nearly half of the portable inhaler market, reflecting their growing importance in both clinical and sustainability contexts. Recognized for their exceptional aerosol performance, deep-lung deposition, and reduced carbon footprint, SMIs are redefining standards in inhaled drug delivery. Their adaptability, user-friendly design, and strong compatibility with biologic therapies make them a vital platform for the next generation of respiratory and systemic treatments.

SMI are the essential “green inhaler”, ahead of pMDIs, nebulisers. They are also the tool for early phase clinical studies and ensure the smoothest transition to finished dosage form and market launch.

About

SMI.London 2026 – Advancing the Science of Soft Mist Inhalers

Building on the insightful discussions started in 2023, SMI.London 2026 continues to serve as the world’s leading hub for knowledge exchange and collaboration between academic researchers, industry innovators, and regulatory experts in inhaled drug delivery.

Participants will gain insights from key opinion leaders and pioneers in the field of inhaled therapeutics, sharing the latest advances in device design, aerosol performance, and formulation science.

SMI.London 2026 will take place on Wednesday, 10 June 2026, at 30 Euston Square, London.

Exhibition and partnership opportunities are available for organisations involved in SMI technologies, analytical services, and drug delivery innovation.

Join us in shaping the future of inhaled therapy.
Let’s make the future together

Speakers

Digital Twin Evaluates Breath Actuated SMI Lung Dose

  • Simulation of aerosol transport and regional deposition using CT-derived airway geometries and a physics-based whole-lung model

Improving ICU aerosol therapy with soft mist technology

  • On-demand absolute humidification using a soft mist nozzle decouples gas flow humidification from heating, while maintaining clinical safety thresholds

  • Improved drug delivery efficiency by reducing undesired deposition in breathing circuits through partial evaporation of drug droplets, for both high-flow nasal cannula (HFNC) therapy and invasive mechanical ventilation (IMV)

  • Bench measurements translated to regional respiratory tract deposition using simulations, providing insights into effective dose in target regions

  • Pulmonary diseases alter regional deposition, highlighting the potential need for adaptive aerosol therapy strategies

Darragh Murnane

Merxin Ltd

Building The Future: Inhaled Therapies In Development

  • A range of novel therapeutic modalities are emerging for respiratory delivery

  • There are few examples of novel modalities with regulatory approvals to guide the pathway for development

  • This talk will examine the types of therapeutic modalities currently in clinical trials and assess progression success through translational phases

  • We will identify the range of therapeutic modalities which inhaler device specialists can expect to manage in the coming years.  

Hao-Ying Li

Researcher, King’s College London

Targeted Delivery Enabled By Rayleigh SMIs

  • Elucidate the essence of the formation of LNP-mRNAs.

  • Insights into the changes of LNP-mRNAs under shear stress (theoretically explain their instability under HFMV)

  • Soft mists for the delivery of LNP-mRNAs to targeted regions in nasal cavity

  • Soft mists for the delivery of LNP-mRNAs to the lungs

  • Some corrigendum of concepts

Laleh Golshahi

PhD, Associate Professor, VCU & Founder & CEO, 3DInhale

How to Tune a Nasal SMI Product

  • Existing pre-clinical tools fail to capture combined device–technique–breathing effects. 

  • Anatomical nasal casts enable controlled multi-parameter deposition evaluation. 

  • Spray design and plume geometry dominate deposition over breathing. 

  • Administration orientation drives regional coverage; generalized guidance is achievable. 

  • Olfactory targeting likely requires device-specific, not generalized, strategies.

Clive P. Page

Professor of Pharmacology, King’s College London

The Ensifentrine Story: A Bifunctional Therapy For Respiratory Diseases

  • The need for new therapies for asthma and COPD

  • Will discuss the discovery and development of ensifentrine

  • First in class inhaled "bifunctional" drug combining anti-inflammatory and bronchodilator activity in a single molecule

  • Positioning of ensifentrine in the treatment of COPD

  • Future developments
