Rolf Lewensohn's Group

Development of novel treatments for lung cancer. Our aim is to develop new oncological treatments in the form of novel drug candidates and precision radiotherapy, with a personalized cancer medicine approach.

From all types of cancer, lung cancer is the leading cause of cancer-related mortality. Each year approximately 1.4 million people die worldwide because of lung cancer. Possibilities to increase survival of lung cancer patients are rapidly emerging. Early stages of lung cancer in the form of a localized intra-thoracic tumor or a tumor with a limited number of metastases may now be attacked with curative intent. However, lung cancer is often detected only at a late stage. Moreover, after an initial response to treatment, therapy-resistant clones inevitably start growing resulting in rapid disease progression. New knowledge of lung cancer-specific mutations, identification of biomarkers to predict therapy response, and understanding of the molecular mechanisms of action of novel drugs opens up for personalization of treatment.

A number of novel drug candidates, among which some are reacting with tumor DNA and/or directed to interfering with DNA repair, are being developed in our laboratory through a full preclinical test system preceding clinical trials. This includes analysis of biochemical mechanisms of action of these drugs and identification of corresponding putative biomarkers to create precision in selecting patients with sensitive tumors for a specific treatment. The research comprises of work on primary tumor material, biobanking thereof, genomics and proteomics analyses, and also in vivo experiments to determine proof-of-principal and pharmacological parameters. We have brought one compound Mel-flufen, which is a conjugate of a peptide and a DNA-alkylator, to phase II clinical trial.

In parallel, we run clinical trials on lung cancer in our clinical trial unit at Karolinska university hospital, in collaboration with pharmaceutical partners. A clinical trial program on precision-based hypofractionated radiotherapy (SBRT) is ongoing and rapidly being further developed. SBRT seems promising in treatment of inoperable tumors, to improve lung cancer survival. In several clinical trials, drug and radiotherapy are also combined as a novel strategy to cure cases with both early localized and early metastasized disease.

Furthermore, the group has a leading role in EurocanPlatform, an EU-funded project to bring together 28 European cancer institutions and organizations, with the aim to improve outcomes for cancer patients and reduce mortality. Within the Karolinska Institutet and Karolinska university hospital, Prof. Lewensohn is the primary initiator of the development of a personalized cancer medicine program. The ultimate goal of this program is to quickly and efficiently translate the latest scientific advances into a concrete improvement of the care for cancer patients.
