This clinical trial is focused on studying advanced solid tumors, specifically Non-Small Cell Lung Cancer (NSCLC) and Renal Cell Carcinoma (RCC). The study involves a treatment called Oncobax®-AK, which is a capsule containing live bacteria known as Akkermansia muciniphila, strain P2261. This treatment will be used in combination with various immunotherapy drugs, including YERVOY (ipilimumab), Tecentriq (atezolizumab), KEYTRUDA (pembrolizumab), OPDIVO (nivolumab), and LIBTAYO (cemiplimab). These drugs are administered through an intravenous infusion, which means they are given directly into a vein.
The purpose of this study is to evaluate the safety and effectiveness of Oncobax®-AK when used alongside these immunotherapy treatments. The study is divided into two phases. In the first phase, the focus is on understanding how safe and tolerable the combination of Oncobax®-AK and immunotherapy is for patients with metastatic NSCLC or RCC who have low levels of Akkermansia bacteria. The second phase aims to assess how well this combination works in treating these cancers.
Participants in the study will receive repeated doses of Oncobax®-AK along with their immunotherapy treatment. The study will monitor the patients’ response to the treatment and any side effects they may experience. The goal is to gather information that could help improve treatment options for patients with advanced NSCLC and RCC. This study is expected to continue until September 2025.
