Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
1. Participant has provided written consent
2. In the Investigator's opinion, the participant is able to understand and comply with protocol requirements, instructions, and protocol stated restrictions and is likely to complete the study as planned
3. Male or female, 18-70 years of age
4. Body mass index (BMI) 18-35 kilogram per meter square (kg/m^2), inclusive
5. A woman of childbearing potential must have a negative serum (beta-human chorionic gonadotropin) pregnancy test at screening
6. Female participants must either:

* not be of childbearing potential defined as: i. Postmenopausal for at least 12 months (that is [i.e.], 2 years of amenorrhea without an alternative medical cause) and a serum follicle stimulating hormone (FSH) level in the postmenopausal range (per reference laboratory), OR ii. Surgically sterile (example [e.g.], underwent total hysterectomy, bilateral oophorectomy, or bilateral tubal ligation/bilateral tubal clips without reversal operation), or otherwise incapable of becoming pregnant, OR
* be of childbearing potential AND
* not heterosexually active (e.g., abstinent or homosexual) from screening until 6 months after study drug administration (or longer, if dictated by local regulations), OR
* if heterosexually active

* have a vasectomized partner (confirmed sterile per verbal account of the participant), OR
* using an acceptable method of birth control from screening and agree to continue to use the same method of contraception throughout the study and for 6 months after study drug administration (or longer, if dictated by local regulations). Oral hormone based contraceptives are not allowed from 14 days before the planned study drug administration until 6 months after the last dose of treatment due to the potential for drug-drug interactions which might undermine their efficacy. An intrauterine device (IUD), being either hormonal (i.e., Intra-Uterine System [IUS*]) or non-hormonal, is considered highly effective and reliable; therefore participants using an IUD/IUS are not required to use additional contraceptive methods (no double-barrier method is required). Other non-oral hormone-based contraception methods (e.g., injectable, implants, transdermal system, vaginal ring) may be continued, but as the interaction of the study drug with hormone-based contraception is unknown, these methods are not considered to be reliable and therefore participants should use a double-barrier method (e.g., male condom+either diaphragm or cervical cap with or without spermicide).

* An IUS does not rely on systemic plasma concentrations and is therefore not expected to be impacted by a potential drug-drug interaction (DDI)

Note 1: Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study drug. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the study and the preferred and usual lifestyle of the participant.

Note 2: A male and female condom should not be used together due to risk of breakage or damage caused by latex friction
7. A post-menopausal female who is receiving hormone replacement therapy and is willing to discontinue hormone therapy 30 days before study drug dosing and agrees to remain off hormone replacement therapy for the duration of the study may be eligible for study participation.

* Male participants must either:
* be surgically sterile (had a vasectomy), or otherwise incapable of fathering a child, OR
* not be heterosexually active (e.g., abstinent or homosexual) from enrollment (Day 1) in the study until at least 6 months after study drug administration, OR
* if heterosexually active:

* have a partner who is postmenopausal (2 years amenorrhea), surgically sterile (e.g., has had a total hysterectomy, bilateral oophorectomy, or bilateral tubal ligation/bilateral tubal clips without reversal operation), or otherwise incapable of becoming pregnant OR
* be practicing an acceptable method of birth control from enrollment in the study (Day 1) and agree to continue to use the same method of contraception throughout the study and for at least 6 months after study drug administration (or longer, if dictated by local regulations). An acceptable method of birth control for male participants is a double-barrier method (e.g., male condom+either diaphragm or cervical cap with or without spermicide).

Note: Male participants with a female partner who uses hormonal contraceptives (oral, injectable, implants) or a hormonal (IUS) or non-hormonal IUD and male participants who are vasectomized or otherwise incapable of fathering a child are not required to use additional contraceptive methods.

Note 1: Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study drug. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the study and the preferred and usual lifestyle of the participant.

Note 2: A male and female condom should not be used together due to risk of breakage or damage caused by latex friction.

NOTE: Contraceptive use by men and women should be consistent with local regulations regarding the use of contraceptive methods for participants participating in clinical studies if these are stricter than what is proposed in these inclusion criteria
8. Participants must agree to refrain from sperm/egg donation from start of dosing through 6 months after the completion of study drug administration
9. Genotype (GT) 1a or 1b or GT2 or 3 chronic hepatitis C (CHC), depending on cohort, with positive Hepatitis C virus (HCV) antibody and a positive HCV ribonucleic acid (RNA) at screening including documentation of CHC infection for at least 6 months. Genotype testing must occur at a screening visit. NOTE: GT1 patients are eligible for inclusion even if they cannot be successfully subtyped unless a specific subtype is required for a cohort
10. Screening HCV RNA viral load greater than or equal to (>=) 50,000 International Units per milliliter (IU/mL), except for participants with compensated cirrhosis (Child Pugh Class A) who may have HCV RNA viral load >=10^4 IU/mL
11. No prior treatment for CHC (defined as no prior exposure to any approved or investigational drug including direct-acting antivirals, and interferon-based treatments)
12. Fibroscan, collected within 6 months of baseline visit, with liver stiffness score less than or equal to (<=) 12.5 kilo Pascal (kPa) to be eligible (except for participants with cirrhosis, see below).

* participants with compensated cirrhosis must meet the Child-Pugh Class A definition (see Appendix G) and at least one of the following criteria: i. Liver biopsy result indicating the presence of cirrhosis (e.g., Metavir F4; Ishak >5) or ii. Fibroscan evaluation with a liver stiffness score >12.5 kPa
13. Participant is otherwise in good health as deemed by the investigator, based on the findings of a medical evaluation including medical history, physical examination, laboratory tests and electrocardiogram (ECG)
14. Willing to avoid prolonged sun exposure and use of tanning devices while taking Simeprevir (SMV) and through 4 weeks of follow up. Participant should also be advised to use a broad-spectrum sunscreen and lip balm of at least sun protection factor >30 to help protect against potential sunburn
