Summary Background The most commonly used second‐line Helicobacter pylori eradication regimens are bismuth‐containing quadruple therapy and levofloxacin‐containing triple therapy, both offering suboptimal results. Combining bismuth levofloxacin may enhance the efficacy of rescue regimens. Aims To evaluate tolerability a regimen containing in patients whose previous H. treatment failed.

Gut microbiota is involved in immune modulation and checkpoint inhibitors (ICIs) efficacy. Single-arm phase II CAVE-mCRC CAVE-LUNG clinical trials investigated cetuximab + avelumab combination RAS wild-type (WT) metastatic colorectal cancer (mCRC) chemo-refractory nonsmall cell lung (NSCLC) patients, respectively. A comprehensive gut genetic analysis was done basal fecal samples of 14 patients from trial with circulating tumor DNA (ctDNA) RAS/BRAF WT microsatellite stable (MSS) disease....
