This study highlights that combining offline, at-line, in-line, and online DLS methods enables thorough monitoring across the entire lipid nanoparticles production process. This integrated approach streamlines operations, supports real-time process adjustments, and ensures dependable quality control both post-production and during storage.

In Vitro In Silico Correlation of Lidocaine HCl Skin Permeation - A Comparative Study of Gel Cream and Bigel formulations

  • Poster

ECP - Mar 2025

Manon Rossano, Delphine Pélisson, Malaury Ducros, Elise Dauphin-Chanard, Philippe Caisse

In this work, the effectiveness of Skin-in-Silico™ software for simulating dermal absorption and permeation of lidocaine hydrochloride in gel, cream, and bi-gel forms was evaluated. By combining in silico predictions with in vitro experiments, we explore the correlation between these methods and their role in optimizing topical drug formulations.

A QbD-based UPLC-ELSD method for quantifying medium-chain triglycerides in Labrafac™ WL 1349 for nanoemulsion applications

Molecules - Jan 2025

Alessio Gaggero, Viktoria Marko, Dalibor Jeremic, Carolin Tetyczka, Philippe Caisse, Jesús Alberto Afonso Urich

This article showcases the development and validation of a robust UPLC-ELSD method, using analytical Quality-by-Design principles, to accurately quantify medium-chain triglycerides in a lipid-based excipient for nanoemulsion applications, ensuring compliance with regulatory standards.

Toward improving the in vitro in vivo correlation of lipid-based formulations using a simplified gastro-intestinal lipolysis protocol

  • Poster

AAPS - Oct 2024

Elise Dauphin-Chanard, Stéphanie Chevrier, Malaury Ducros, Philippe Caisse

Lipid-based formulations (LBF) enhance the oral bioavailability of poorly water-soluble drugs by maintaining them in a solubilized state during digestion. This study aims to establish a robust protocol to evaluate the impact of gastro-intestinal lipolysis on LBF performance, using cinnarizine as a model drug.

Rheology as a tool for characterizing topical product formulations: impact of solubilizer variation on stability and structure

  • Poster

CRS - Jul 2024

Manon Rossano, Delphine Pélisson, Elise Dauphin-Chanard, Philippe Caisse

The use of solubilizers in a topical formulation helps solubilization of poorly soluble APIs. Therefore, it is essential to have a formulation chassis that can be modulated to incorporate this quantity of solubilizer. In this poster, the influence of different excipients as solubilizers and their variation on the stability and rheological properties of topical creams is investigated.

Formulation forum – A Quick Approach for Evaluation of Drug-Excipient Compatibility: Case of Acetylsalicylic Acid

  • Whitepaper

Drug Development & Delivery - 2021

Dr. Masumi Dave, Rollie Fuller

In this study, the authors monitor acetylsalicylic acid (ASA) hydrolysis in different formulations using UPLC and TAM with the objective of comparing these methods for agreement, speed, and efficiency in predicting drug stability. In parallel, we assess the impact of the excipient choices on the stability of the ASA.

TAM Technique for Identifying API-Lipid Excipient Compatibility Issues Upstream in the Development Process

  • Poster

AAPS PharmSci 360 – Washington DC (USA)  - Nov 2018

Masumi Dave, M.S., Jason Le Pree, Ph.D., R.Ph. – Gattefossé USA

In this study the authors showed that Thermal Activity Monitoring is a useful technique to detect at early stage potential interaction between APi and excipients, using less time and resources than conventional techniques. 

TAM technique is used routinely in Gattefossé North America Technical Center of Excellence to speed up formulation development.
