CMMC Symposium in Molecular Medicine

From Concepts to Clinic:
a New Era of Nucleic Acid Therapeutics

September 18 - 20, 2023 in Cologne, DE

Many thanks to our speakers, participants, sponsors and supporters!

We were delighted to welcome 320 participants from 11 different countries at the CMMC Symposium 2023 and we were particularly pleased that junior researchers (PhD, Master and Medical Students) were represented by 155 participants.

Nucleic acid-based compounds are highly target-specific and it is now the time to overcome the last hurdles towards the widespread application of this therapeutic opportunity in a growing number of diseases. This goal requires an in-depth understanding of the chemical, biological and clinical challenges in the field. The CMMC Symposium 2023 addressed these challenges and successfully contributed to intensify the interdisciplinary exchange between physicians, clinical scientists, molecular biologists, bioinformaticians, physicists, chemists and other life science professionals.

A special thank you to all speakers for their commitment, time and engagement in making this symposium an outstanding event providing a fascinating and impressive journey of nucleic acid therapeutics spanning the arch from basic science to therapy in the clinic.

Another highlight was the poster session, which was used intensively for scientific exchange and during which the three best poster contributions were awarded with the CMMC Poster Prize of the CMMC Symposium 2023.

The lively discussions after the talks and during the poster presentations, as well as the scientific exchange throughout the meeting, were extremely fruitful and remarkable resulting in a vibrant atmosphere during the entire conference. The discussions following the inspiring talks will certainly continue in the various departments of the medical and science faculties for a long time.

Finally, we would like to express our sincere gratitude to the Fritz Thyssen Stiftung and the research institutions - CECAD, the CRCs 1451, 1403, 1310, 1399, 1530 and the KFO 329 as well as the Cologne Convention Bureau - for their support. We were also pleased to interact with our industry sponsors and the chance to exchange ideas and to network with the participants directly on site.

Many thanks to all of you - your participation has contributed significantly to the success of the CMMC Symposium 2023.

Yours sincerely,

The annual, international Symposia Series in Molecular Medicine is one key highlight at the biomedical and life science campus of the University of Cologne. Originally named ‘Ernst Klenk Symposia’, the series was renamed upon the 25th anniversary of the Center for Molecular Medicine Cologne, and is now organized as the ‘CMMC Symposium in Molecular Medicine’. 2023 will be the 37th anniversary of this premier biomedical science meeting, which brings together over 400 national and international participants, including both Junior and Senior Faculty and other stakeholders from all over Europe and abroad.


Sustainability and climate protection are of the highest and most urgent importance.
The CMMC Symposium 2023 will also contribute to sustainability in some aspects.

  • we will go paperless – QR codes for program and poster abstract book
  •  food & drinks
    - we offer vegetarian or vegan food
    - we offer water (carbonated and non-carbonated) only in reusable bottles
    - we use water glasses and porcelain coffee cups and plates
  • waste separation - we separate plastic/recyclable (yellow), paper (blue) and residual (black) waste in garbage cans. Please check for the matching colour.
  • conference bags made of fabric (OEKO-TEX® STANDARD 100)
  • re-using the name tags - please return your name badge on your last day of the symposium
  • good accessibility by train and public transport - you can reach Cologne from all over Germany and Europe by train. After reaching Cologne main station, you only need one streetcar to get to the venue.  Special offer from the “Deutsche Bahn”- please check “Information” on our website
