Excerpt
Up until the last decade, the treatment options for metastatic renal cell carcinoma (mRCC) patients were limited. mRCC is resistant to systemic cytotoxic chemotherapy [
1] and cytokine-based therapies like IFN-α and IL-2 resulted in modest response rates and little survival benefit [
2]. Over the past decade, the treatment of mRCC has changed considerably with the introduction of targeted therapies and, more recently, immune checkpoint inhibitors (ICI) [
3]. Although the introduction of targeted therapies has markedly improved patient outcome, they rarely induce complete responses, and most patients eventually develop resistance to these therapies. Clinical trials with ICI nivolumab (anti PD-1) and ipilimumab (anti CTLA-4) in mRCC reconfirmed the relative tractability of this tumor type to immunotherapy. However, the objective response rate of mRCC patients who received combination treatment of nivolumab and ipilimumab is still only 42% and comes at the cost of substantial (although often manageable) toxicity [
4]. Therefore, further exploration of immunotherapeutic combination approaches is warranted for the treatment of mRCC. …
