Abstract
Cervical cancer (CC) patients, especially those with advanced disease, are urgently in need of new treatment options that can increase their survival rate and quality of life. A promising strategy is immunotherapy, however, only a minority of patients responds to it because the cancer has developed mechanisms that evade its effects. In recent years, the RANKL/RANK signaling pathway has been implicated as one such mechanism, as it allows many cancer types - including CC - to circumvent the immune response by disrupting the communication of the immune cells. Supported by our first results, we strongly believe that blocking the RANKL/RANK signal can release the brakes on the immune system and reinvigorate the tumor's susceptibility to immunotherapy. We therefore aim to expose the best possible immunotherapeutic partner(s) for anti-RANK(L) therapy in order to achieve the most optimal anti-tumor immune effects. For this, we have unique access to CC samples retrieved from patients before and after anti-RANKL monotherapy, which we will thoroughly investigate to reveal immune related changes. Thereafter, we will perform additional laboratory tests that will allow us to pinpoint one best-in-class anti-RANKL combination strategy, which we will further optimize in CC mouse models. Finally, this project will validate a novel imaging technique to stratify patients and monitor treatment response for this therapy, thereby minimizing treatment - and economic burden.
