| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| Phase 1: Characterize the safety profile and  tolerability of repeated doses of Oncobax®-AK administered in combination with PD-L1-based immunotherapy in metastatic NSCLC or RCC patients deficient in Akkermansia. 
 Phase 2:  Characterize the efficacy of repeated doses of Oncobax®-AK administered in combination with PD-L1-based immunotherapy in metastatic NSCLC or RCC patients and deficient in Akkermansia.
 |  | 
| E.2.2 | Secondary objectives of the trial | 
| Phase 1: Characterize the: - presence of Akk. p2261 in the  gastrointestinal tract of patients following Oncobax®-AK administration

 - immuno-modulatory effects of Oncobax®-AK administration
 - changes in patients’ intestinal barrier fitness.
 
 Phase 2: Characterize the:

 - presence of Akk. p2261in the gastrointestinal tract of patients following Oncobax®-AK administration
 - impact of Oncobax®-AK administration on the patients’ gastrointestinal microbiota composition
 - immuno-modulatory effects of Oncobax®-AK administration
