Research interests/projects:

SW co-leads the translational research lab at the section for Cellular therapy, OUS, a newly established pre-clinical entity directly connected to the immunomonitoring unit. SW leads the molecular biology of the T-cell receptor (TCR) and the Chimeric Antigen Receptor (CAR) development platforms.

The TCR platform has led to the filling of numerous patents, the establishment of a biotech (Zelluna Immuntherapy AS, 2016) and the first TCR tested in human in Norway (ClinicalTrials.gov Identifier: NCT03431311).

The CAR platform has completed the pre-clinical development of 2 candidates and is working on around 15 new constructs, most of them directed against solid tumours.

Advanced universal therapeutic solutions are also in our pipeline (3 patents), and different innovative tools in the immunotherapeutic field (vaccination, effector cell improvement, etc.).
