Who can take part

You may be able to join if

1. Previously untreated patients with histologically- or cytologically- documented NSCLC who present stage IIA, IIB, IIIA or IIIB (only T3N2) disease (according to 8th version of the International Association for the Study of Lung Cancer Staging Manual in Thoracic Oncology)
10. For female patients of childbearing potential, agreement (by patient and/or partner) to use a highly effective form(s) of contraception that results in a low failure rate (< 1% per year) when used consistently and correctly, and to continue its use for 6 months after the last dose of trial treatment.
11. For male patients with female partners of childbearing potential, agreement (by patient and/or partner) to use a highly effective form(s) of contraception that results in a low failure rate [< 1% per year] when used consistently and correctly, and to continue its use for 6 months after the last dose of trial treatment. Male patients should not donate sperm during this study and for at least 6 months after the last dose of trial treatment.
12. Oral contraception should always be combined with an additional contraceptive method because of a potential interaction with the study drugs. The same rules are valid for male patients involved in this clinical study if they have a partner of childbirth potential. Male patients must always use a condom.

14. Patients is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up

You likely can't join if

1. Patients with known sensitizing mutation or an amplification in the epidermal growth factor receptor (EGFR) gene or any variety of alterations of ALK oncogene.
10. Pleural or pericardial effusion, both will be considered indicative of metastatic disease unless proven otherwise. Patients with pleural effusion not visible on chest-X-ray or too small to perform diagnostic puncture safely may be included.
11. Patients who have experienced untreated and/or uncontrolled cardiovascular conditions and/or have symptomatic cardiac dysfunction. Patients with a significant cardiac history, even if controlled, must have a LVEF > 50% within 12 weeks prior to randomization.
12. Positive test for HIV. All patients will be tested for HIV prior to inclusion into the study; patients who test positive for HIV will be excluded from the clinical study.
13. Patients with positive test for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus ribonucleic acid (HCV antibody) indicating acute or chronic infection. Patients with past hepatitis B virus (HBV) infection or resolved HBV infection (defined as the presence of hepatitis B core antibody [HBcAb] and absence of HBsAg) are eligible only if they are negative for HBV DNA (vaccinated patients are excluded). Patients positive for hepatitis C virus (HCV) antibody are eligible only if PCR is negative for HCV RNA."
14. Patients with history of allergy to study drug components/excipients or allergy to Rifaximin
