Quality & Equivalence of Topical Products & NaNOTECHNOLOGY CHALLENGES hybrid workshop

On 6 April 2021


EMA’s proposed guideline on quality and equivalence of topical products - future advances and challenges of nanotechnology

Realising the new guideline on EMA Quality and Equivalence of Topical Products will be enacted soon and such guideline will have both immediate as well as long term consequences on the industry, Dr. Hasler-Nguyen thus decided to organise this special workshop by bringing together a panel of four international experts, who will share their research and practical experiences on the challenges and potential benefits of this new guideline. By contrast, nanotechnology, which brings innovation in medicines development has not yet any guideline.  Nanotechnology challenges will be addressed too.

Panel Discussion







Professor Kalia has worked in biopharmaceutics (speciality: transdermal drug delivery), first at the University of California – San Francisco since 1994 and since 1997 at the University of Geneva.

He has published ~130 papers (h-index 49 (8007 total citations (Harzing’s Publish or Perish, v.; 59 papers as corresponding author), 17 book chapters and presented ~180 communications at national / international conferences and he is a co-inventor on 4 patents. Currently he serves on the Editorial Boards of the European Journal of Pharmaceutics and Biopharmaceutics and Expert Opinion on Drug Delivery; He is also a reviewer for several journals in the fields of pharmaceutical and biomedical sciences.


Professor Richard Guy received an M.A. in Chemistry from Oxford University, and his Ph.D. in Pharmaceutical Chemistry from the UCL School of Pharmacy. He has held academic posts at the University of California, San Francisco and the University of Geneva. In 2004, he joined the University of Bath as Professor of Pharmaceutical Sciences in the Department of Pharmacy & Pharmacology. Dr. Guy’s research focuses on skin barrier function characterization, transdermal drug delivery, enhancement of percutaneous absorption, iontophoresis, noninvasive biosensing, and the prediction and assessment of skin penetration and topical bioavailability. He has published 380+ peer-reviewed articles and over 70 book chapters. He has co-authored one book, co-edited 7 others, and he is co-inventor of 12 patents. In 2016, he was awarded the degree of Doctor of Science from Oxford University and the Maurice-Marie Janot Award from APGI for original and innovative research in pharmaceutics, biopharmaceutics and pharmaceutical technology. Having received the Founders’ Award of the Controlled Release Society (CRS) in 2013, Dr. Guy was the first recipient of the CRS Transdermal Delivery Kydonieus Foundation Award in 2018.

Professor Mühlebach is a trained hospital pharmacist and pharmacologist. He worked for 25 years as head pharmacy in the hospital of Biel/Bienne and Aarau (Switzerland). He got his venia docendi in 1993 in Bern and was promoted professor for pharmacology and hospital pharmacy 2004 at the University of Basel. He worked from 2005-2008 with the National Agency for Therapeutic Products (Swissmedic), was head of the pharmacopoeia and of their delegation at EDQM in Strasbourg. With his role in Industry (Vifor Pharma Ltd from 2009-2019 as a regulatory science lead for Non-Biologcal Complex Drugs (NBCDs) / Nanomedicines) he focused on the regulatory and scientific challenges with these products and their follow-on versions (similars) and their appropriate use also as the chair of the NBCD Working Group at Lygature in the Netherland. Most of his peer-reviewed publications in pharmacology, hospital pharmacy, clinical nutrition, nanomedicines, and regulatory sciences, are cited in PubMed. Based on 230 articles, several books/book chapter (12), Google Scholar indicates a citation number in total (since 2014) of 2967 (2225), an h-index 24 (18) and an i10 index of 35 (31). A total of over 400 oral presentations accumulated over time. Stefan Mühlebach is also a member and Fellow of the Swiss Academia of Pharmaceutical Sciences, serving as Vice-president from 2009-2018. He holds numerous national and international scientic awards and got in 2019 an honorary doctorate from the Pharmacy Faculty of the Semmelweis University for his multiple academic contributions in pharmacy.
