   • Total bilirubin >1,5 x ULN (except for hyperbilirubinemia caused by Gilbert's syndrome)
   • Alanine Transaminase (ALT) activity, Aspartate Transaminase (ASPAT) >2,5 x ULN
   • Alkaline phosphatase activity >2,5 x ULN
3. Prior treatment with any unauthorized medication or investigational treatment before the 5 half-lives of that substance or 4 weeks prior to study entry (a longer period of time should be assumed), or subjects currently enrolled to other interventional clinical trials.
4. Concomitant malignancy or history of a malignancy with a significant potential impact to tolerability or effectivity of iCHRTL.
5. Chronic or active infection requiring antibiotic, antifungal or antiviral treatment, such as, but not limited to: chronic kidney infection, chronic respiratory tract infection with bronchospasm, tuberculosis or active hepatitis C virus infection.

10. Active hepatitis B virus (HBV) infection, defined as having a positive Hepatitis B surface antigen (HBsAg) test. Moreover, in case of a negative HBsAg test result but a positive Hepatitis B core Antibody (HBcAb) test result (regardless of HBsAb status), HBV DNA should be determined and in case of a positive result the patient cannot be included to the study.
11. Active hepatitis C virus (HCV) infection, defined as having a positive Hepatitis C Antibody (HCAb) test, in which case Hepatitis C virus recombinant immunoblot assay (HCV RIBA) should be determined from the same sample to confirm the result.
12. Pregnancy or breastfeeding (women of childbearing potential must have pregnancy test performed during screening).
13. Women of childbearing potential, including women whose last menstrual period occurred in less than one year before screening, who cannot or do not want to use adequate contraception methods from the beginning of the study until 6 months after the last dose of study drug.
