Next-generation nanotechnology know-how, today.
Creating formulations that are truly effective means finding an answer to the question of solubility – and that answer can be found in leon’s unique approach to nano. For New Chemical Entities and generics alike, our intelligence in nanotechnology provides a clear solution for addressing poor solubility and smoothing the path for downstream processing to answer unmet patient needs and unlock new value from APIs for pharmaceutical partners.
It is based on patented technology to deliver a classic bottom-up approach to the synthesis of SMART nanoparticles or microparticles. This results in the continuous precipitation of particle sizes for nano between 10nm and 1000nm and for micro 1-70 µm with consistent reproducibility and at a cost comparative to standard technologies.
Our definition of SMART
Stable crystalline or polymeric particles
Measurable tailored size: 10-1000nm & 1-70µm
Achievable easy scale-up: bench to commercial
Relevant for all application forms
Timebound: fast continuous precipitation
< 0.1ms easily integrated into downstream processes
Scalability is built into our development pathway, with easy scale-up facilitating transfer between the process used to test prototype nano formulations and the process to support clinical and commercial availability. With us, new formulations can be developed faster and the process successfully validated sooner, so that positive impacts can be felt by patients more quickly
- Standardized, continuous processing
- Easily scalable
- Proprietary technology
- Particle tolerances between 10nm-1000nm
- Suitable for range of drug delivery methods and dose formats
Our technology: High-precision particle synthesis.
At leon, we employ proprietary nano technology (including (MJR®)) to provide a highly controlled environment for the repeatable production of stable nanoparticles between 10nm and 1000nm in size.
Because we take a bottom-up approach to particle synthesis, we avoid the known difficulties associated with top-down nano methods, such as wet-milling, where the presence of heat and the impact of shearing, together with the inherently high investment cost and the high failure rate, make it an unsuitable option for many candidate molecules and their organizations.
leon can quickly and reliably produce a wide range of nano particles by tailoring to the API and modifying process conditions. These include surface-stabilized nanocrystals, micelles, liposomes, nanoemulsions, polymer nanoparticles and even solid lipid nanoparticles. Our proprietary approach shares the same fundamental process for small-scale testing as it does for full-scale production, providing a swift and cost-effective route to commercial development.
How it works
- A solvent and non-solvent collide inside the reactor’s chamber.
- This results in the precipitation of insoluble compounds.
- Nanoparticles suspended in the liquid are ready for downstream processing.
leon offers a broad range of particle types to meet a variety of needs, whenever there is a need to re-produce easily and with scale, including:
- Surface-stabilised crystalline nanoparticles
- Polymeric nanoparticles
- Core-shell nanoparticles
- Solid-lipid nanoparticles
