A Study of the Safety and Effectiveness of Simeprevir and Sofosbuvir for Patients With HIV and Hepatitis C

This is a research study of an investigational combination of two hepatitis C medications
call sofosbuvir (SOF) and simeprevir (SMV). Both medications are approved by the U.S. Food
and Drug Administration (FDA) for treatment of hepatitis C in combination with other
medications. The combination sofosbuvir and simeprevir has not been approved by the FDA and
is being tested as an investigational combination in research studies such as this. The
purpose of this study is to see if SOF + SMV given for 12 weeks is safe and able to clear
the Hepatitis C virus (HCV) from subjects who are co-infected with HIV-1 and who have
scarring of the liver (fibrosis of 3 or 4 on a scale of 0-4, with 4 as the most scarring,
also known as cirrhosis).

This study is an investigator-initiated clinical trial sponsored by University of
California, San Francisco (UCSF), with support and the study drug simeprevir provided by
Janssen Scientific Affairs, LLC.

Inclusion Criteria:

- Willing and able to provide written informed consent

- Male or female, age ≥ 18 years

- Body mass index (BMI) ≥ 18 kg/m2

- HCV RNA ≥ 104 IU/mL at Screening

- HCV genotype 1 at screening or with prior documentation. Any non-definitive genotype
results will exclude the subject from study participation

- Chronic HCV infection (≥ 6 months) documented by prior medical history or liver
biopsy

- Fibrosis determination: Fibrosis of Metavir F3/F4 may be established by one of the
following:

1. Liver biopsy at any point in time with Metavir score F3/F4, or equivalent on an
alternative scale.

2. Fibroscan ≥ 9.5 kPA

3. FibroSURE: ≥ 0.58

- Liver imaging within 12 months prior to Baseline/Day 1 is required in subjects with
known cirrhosis to exclude hepatocellular carcinoma (HCC). Acceptable liver imaging
includes ultrasound, CT scan or MRI.

- HCV treatment status of one of the following:

1. HCV Treatment-Naive: No prior exposure to any IFN, RBV, or other approved or
experimental HCV-specific DAA agents

2. HCV Treatment-Experienced: Virologic failure after treatment with PEG-IFN+RBVor
standard IFN +RBV. Prior exposure to HCV polymerase or protease inhibitors is
exclusionary. Prior treatment experienced patients will be categorized as one
of the following:

i. HCV Treatment-Intolerant: Subjects that discontinued HCV treatment due to
development or significant worsening of a treatment related adverse event ii. Null
responder: HCV RNA < 2 log10 decline during first 12 weeks of treatment iii. Partial
responder: HCV RNA ≥ 2 log10 decline during first 12 weeks of treatment but stopped
therapy due to inadequate virologic response iv. Relapse : Undetectable HCV RNA (HCV
RNA
- HIV-1 infection as documented by HIV-1 antibody at screening or any time prior to
screening

- HIV treatment status: For subject receiving ART, HIV RNA must be < 40 copies/ml at
screening and <200 copies/ml for at least 12 weeks prior to screening. Changes in
therapy during the 12 weeks prior to enrollment permitted as long as not due to HIV
treatment failure.

- HIV ART allowed in this study are the following and should be administered per the
prescribing information in the package insert:

- NRTIs: emtricitabine, lamivudine, tenofovir, abacavir

- Maraviroc

- Integrase inhibitors: dolutegravir or raltegravir

- NNRTI's: rilpivirine

- Enfuvitide Fixed dose combinations are permitted.

- Screening ECG without clinically significant abnormalities

- Subjects must have the following laboratory parameters at Screening and at Pre-entry
(if pre-entry visit is required):

- CD4 T-cell count >100 cells/mm3 if on ART, ≥ 350 cells/mm3 if not on ART

- ALT ≤10 x the upper limit of normal (ULN)

- AST ≤10 x ULN

- Direct bilirubin ≤1.5 ULN

- Creatinine clearance (CrClr) ≥50 mL /min, as calculated by the Cockcroft-Gault
equation

- Hemoglobin ≥10 g/dL

- Albumin ≥3g/dL

- INR ≤ 1.5 x ULN unless subject has known hemophilia or is stable on an
anticoagulant regimen affecting INR

- Alpha feto protein (AFP) levels <50. If ≥ 50, they should have a liver imaging
study (eg, ultrasound, CT scan, MRI) showing no evidence of hepatocellular
carcinoma within 3 months of study enrollment

- Female subjects of reproductive potential (defined as women who have not been
post-menopausal for at least 24 consecutive months, ie, who have had menses within
the preceding 24 months, or women who have not undergone surgical sterilization,
specifically hysterectomy and/or bilateral oophorectomy or bilateral salpingectomy)
must have a negative serum pregnancy test with a sensitivity of at least 25 mIU/mL
performed during screening, within 48 hours prior to study entry.

- All subjects must agree not to participate in a conception process (eg, active
attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization).

NOTE: Female candidates who are pregnant or breastfeeding are not eligible. A male
candidate who has a pregnant female partner is not eligible for the study.

- When participating in sexual activity that could lead to pregnancy, all subjects must
agree to use at least two non-hormonal forms of contraceptive simultaneously while
receiving protocol-specified medications, and for 4 weeks after stopping the
medications. Such methods include:

- Condoms (male or female) with or without a spermicidal agent

- Diaphragm or cervical cap with spermicide

- Intrauterine device (IUD)

- Tubal ligation NOTE: Providers and subjects should be advised that not all
contraceptive choices listed above can prevent HIV transmission and that some
may actually increase the risk of HIV acquisition. Study subjects who are
sexually active with HIV-1 negative or unknown HIV-1 serostatus partners should
be advised that they need to consider effective strategies for reducing the risk
of HIV transmission, as well as meeting the requirement for effective
contraception during their participation in the study. Study subjects should
discuss contraceptive choices and HIV risk reduction methods with their health
care provider.

- Subjects who are not of reproductive potential (women who have been post-menopausal
for at least 24 consecutive months or have undergone hysterectomy and/or bilateral
oophorectomy or salpingectomy or men who have documented azoospermia or undergone
vasectomy) are eligible without requiring the use of contraceptives. Acceptable
documentation of sterilization and menopause is specified below.

Written or oral documentation communicated by clinician or clinician's staff of one of the
following:

- Physician report/letter

- Operative report or other source documentation in the patient record (a laboratory
report of azoospermia is required to document successful vasectomy)

- Discharge summary

- Follicle stimulating hormone-release factor (FSH) measurement elevated into the
menopausal range as established by the reporting laboratory.

- Subject must be able to comply with the dosing instructions for study drug
administration and able to complete the study schedule of assessments.

Exclusion Criteria:

- Hepatic decompensation at any point in time (includes variceal bleeding, hepatic
encephalopathy, and ascites)

B, acute hepatitis A, hemochromatosis, or homozygote alpha-1 antitrypsin deficiency.

- Serious illness including malignancy within 24 weeks prior to study entry, or other
chronic medical conditions that in the opinion of the site investigator may preclude
completion of the protocol.

- Presence of active or acute AIDS-defining opportunistic infections within 12 weeks
prior to study entry.

- Use of any prohibited concomitant medications

- Child-Pugh Score 6.2.2 Pre-entry>6
