Exosome Nasal Formulation Development

Innovating Non-Invasive Delivery Routes for Next-Generation Exosome Therapeutics

Why Inhaled Exosomes?

Inhaled delivery offers unique advantages for exosome therapeutics, including: 

  1. Targeted Pulmonary Delivery

    Ideal for lung-related diseases such as asthma, COPD, ARDS, fibrosis, and viral respiratory infections.
    Provides high local concentration with reduced systemic side effects.

  2. Non-Invasive and User-Friendly

    Eliminates injectable routes, have the potential to improve patient compliance towards treatment, and supports at-home administration.

  3. Rapid Absorption & Systemic Reach

    Nasal delivery enables fast uptake and the potential for nose-to-brain transport via the olfactory pathway.

  4. Maintained Exosome Integrity

    Formulations are designed to preserve vesicle structure, bioactivity, and therapeutic performance throughout aerosol generation.

  5. Scalable & Stable Formats

    Spray-dried and freeze-dried exosomes minimize cold-chain reliance and simplify global distribution.

Overview

Esco Aster offers advanced formulation solutions for inhalation-based exosome delivery, enabling developers to transform exosome candidates into nasal spray, nebulizer-ready, or dry powder inhalation products. By integrating specialized particle engineering, stability studies, and aerosolization expertise, we support the development of inhaled exosome therapeutics designed for respiratory, neurological, and systemic indications.

Our Formulation Capabilities

Nasal Spray Exosome Formulation 

Esco Aster formulates exosomes for nasal delivery, optimizing for efficient mucosal absorption and stability.
Available formats include:

This route supports rapid systemic uptake and potential nose-to-brain delivery.

Nebulizer-Compatible Exosome Formulations  

Exosomes can be engineered for compatibility with common jet and mesh nebulizers, ensuring structural integrity and consistent aerosol performance.
Capabilities include: 

Each formulation is optimized to withstand aerosolization stress without compromising therapeutic potency.

Spray-Dried & Freeze-Dried Exosome Powders 

For long-term stability and global distribution, Esco Aster offers advanced drying approaches: 

These enable reduced cold-chain requirements and scalable manufacturing.
