ICPR 2024, 6-8 June > Speakers > Friederike Holze

Friederike Holze, PhD

Postdoctoral researcher at University Hospital Basel


At ICPR 2022, Dr. Friederike Holze will present the preliminary results of the first study investigating the effect of LSD-assisted therapy in people suffering from psychiatric anxiety disorders. She will present the development of the study, the background of psychedelic research in Switzerland and venture a view into the future of LSD research.



Dr. Friederike Holze received her MSc in Pharmacy from the University of Basel in 2016. During her Master’s she worked in the Psychopharmacology research lab of Prof. Matthias E. Liechti at the University Hospital Basel where she conducted a clinical study investigating the emotional and social cognitive effects of alcohol. In 2017, she rejoined the research group of Prof. Matthias Liechti where she received her PhD in 2021 and where she is currently affiliated as a postdoctoral researcher. 

Her research interests lie in the pharmacology of psychoactive substances, in particular psychedelics. She conducted several Phase I studies investigating the pharmacokinetics and pharmacodynamics of LSD and established a dose-effect relationship in doses from 5-200 µg. Additionally, she described the distinct acute pharmacological effects of LSD, MDMA and d-amphetamine. In this function, she has accompanied over 200 psychedelic experiences in healthy test subjects. Furthermore, she is involved in a Phase II study investigating the potential therapeutic effects of LSD in patients suffering from anxiety disorders without relation to somatic illnesses.

From 2017 to 2021, Dr. Holze and a team of therapists conducted a phase II trial in collaboration with Prof. M. Liechti’s research group at the University Hospital of Basel, investigating LSD-assisted therapy in people suffering from anxiety symptoms in severe somatic diseases or in psychiatric anxiety disorders. The team used a double-blind, randomised, 2-period, cross-over design in 40 patients employing well-validated and internationally established questionnaires and tools. This is the largest study investigating LSD as therapy in recent times, and it is an example of  successful research collaboration between university know-how and private practice hands-on psychiatric research.

Dr. Holze will present the development of the study, the background of psychedelic research in Switzerland, show the (yet unpublished) results, and venture a view into the future of LSD research.
