Study Details

Study Description

Brief Summary

MS-20 was approved as the first oral cancer adjuvant new drug indicated for ameliorating fatigue and appetite loss associated with cancer chemotherapy via reshaping human gut ecosystem and restoring immunity. MS-20 has also been shown to be anti-PD-1 booster by activating tumor-infiltrating lymphocytes (TILs) in mice cancer models, particularly promoting migration of TILs into tumors and increasing the amount of TILs inside tumors. Therefore, this study is designed to explore the safety and relationship between gut microbiome and potential clinical outcomes in NSCLC patients under combination therapy with pembrolizumab and MS-20.

The life expectancy is not less than 3 months.
The subject whose liver and kidney functions must meet all of the following conditions:

Liver function: aspartate aminotransferase (AST) value < 2.5 x ULN, alanine aminotransferase(ALT) value < 2.5 x ULN and total bilirubin (T-bilirubin) value < 1.5 x ULN. For the subjects who have liver metastases, total bilirubin value should be < 5 x ULN.
Kidney function: Serum creatinine value < 1.5 x ULN. If subject's serum creatinine value is ≥ 1.5 x ULN, his/her creatinine clearance value should be > 40 mL/min based on Cockcroft and Gault formula.
