Brief summary:
Retrospective/Prospective, open-label study using sofosbuvir based DAA therapy to treat HIV/HCV coinfected pre or post liver transplant participants

Detailed description:
Approximately fifty HIV/HCV coinfected patients with decompensated liver disease will be enrolled in the study. Ten (up to twenty) subjects will be treated with FDC SOF/LDV pre or post liver transplant and followed prospectively. Forty + subjects will be enrolled retrospectively with the intent to capture all patients who have been exposed to sofosbuvir based DAA therapies at participating sites since 1/2014, and to mirror the population being enrolled prospectively.

In addition, participants in the retrospective arm will be contacted to consent to one prospective study visit for liver staging to determine rates of reversal of decompensation, reversal of cirrhosis and improvements in graft survival post treatment, and for future contact by the NIH Clinical Center to assess longer term outcomes when this study ends.

INTRODUCTION 
 
We invite you to take part in a medical research study at the [ NAME OF CENTER]. Your study doctor(s) 
[NAMES, MD] from the [NAME OF CENTER] will explain the study to you. 
 
First, we want you to know that: 
 
Taking part in this research is entirely voluntary. 
 
You may choose not to take part, or you may withdraw from the study at any time. In either case, you will 
not lose any benefits to which you are otherwise entitled. 
 
You may receive no benefit from taking part. The research may give us knowledge that may help people in 
the future. 
 
Second, some people have personal, religious or ethical beliefs that may limit the kinds of medical or research 
treatments they would want to receive (such as blood transfusions). If you have such beliefs, please discuss them 
with your [NAME OF CENTER] doctors or research team before you agree to the study. 
 
A description of this clinical trial will be available on http://www.Clinicaltrials.gov. This Web site will not include 
information that can identify you. At most the Web site will include a summary of the results. You can search this 
Web site at any time. 
 
Now we will describe this research study. Before you decide to take part, please take as much time as you need to 
ask any questions and discuss this study with anyone at [NAME OF CENTER], or with family, friends or your 
personal physician or other health professional. 
 
Study Team 
Your study team consists of doctors, nurses and other specialized medical professionals, who are experienced in 
taking care of patients with hepatitis C virus (HCV). You will be interacting with some if not all of the study team 
members at specific study visits. However, a study team member will always be available to you if you have a 
question about the study, your response to treatment, or the study drugs. 
 
 
Why is this study being done? 
You are being asked to participate in this study because you have HIV infection and you have liver disease caused 
by infection with HCV. Your blood tests show that the HCV infection continues to be present (i.e., the virus continues 


3 
 
to reproduce), causing a chronic infection. Currently there are about 4 million people with HCV in the US and only 
about 10 – 20% are being treated for their HCV, many with severe or advanced liver disease. In your case you have 
been diagnosed as having severe liver disease and your HCV virus is still active. 
 
Sofosbuvir (SOF) and ledipasvir (LDV) are combined in one pill called HARVONI that is now approved in the US for the 
treatment of chronic hepatitis C genotype 1 infection in adults. This study will also enroll participants with genotypes 1, 
4, 5 and 6. The safety, tolerability and efficacy of SOF/LDV have not been established in patients with decompensated 
cirrhosis (clinical evidence of cirrhosis such as internal bleeding, fluid in the belly, or yellowing of the eyes and skin) or 
after liver transplantation. The purpose of this study is to determine whether SOF/LDV in combination for 12 to 24 
weeks can be safe, tolerated and effective for treating HCV infection before or after liver transplantation in people who 
also have HIV infection. This drug works by blocking the HCV from dividing in your body. 
 
How many people will take part in the study? 
This study will enroll 10 - 20 participants with HIV infection who also have HCV infection with severe liver disease or 
who have had a liver transplant. Participants will receive 12 weeks of SOF/LDV (up to 24 weeks for pre liver 
transplant participants and for people who have had a liver transplant and now have cirrhosis). SOF/LDV for 12 weeks 
has been shown to be effective in HCV patients with HIV with high cure rates. Rates of cure were slightly lower in 
people who had failed previous HCV treatment or had cirrhosis. Increasing SOF/LDV therapy from 12 to 24 weeks 
increased the cure rate in prior studies.  
 
The drug will be provided by the manufacturer, Gilead Sciences, Inc. You will be followed during the treatment and 
for 24 weeks afterwards. After starting the study drugs, if you have to stop them for any reason, you will be 
offered treatment with an effective regimen based on prior response to the treatment, whether the HCV has become 
resistant or not, and other factors.  
 
 
 
 
 
What will happen if you take part in this research study? 
 
Your participation in the study involves multiple visits to the [name of center] over a period of up to 1 year from 
the start of study treatment. In general, each visit will require collection of blood to be used for safety labs (blood 
counts, blood clotting tests, kidney function, muscle and liver tests, blood minerals, and electrolytes), as well as labs to 
determine the amount of HCV in your blood (HCV viral load), and levels of SOF/LDV. Your weight will also be 
measured at all main study visits. All these tests are routinely performed for the care of individuals with chronic 
HCV or HIV infection or who have had a liver transplant.  
 
Participation in this protocol might affect the timing of liver transplantation if you have not had one yet.  If a liver 
becomes available before you have completed therapy, your physician will discuss with you the best course of action 
and you will collectively decide how to proceed. 
 
Study Drugs 
The study drugs include SOF/LDV. These are given as a single combination pill each morning either with or without 
food. The pill includes 400mg of SOF and 90mg of LDV. Because we will check the levels of the study drugs in your 
blood during your visits, we ask that you wait until after your blood is drawn to take your dose on study visit days. 
We will supply enough study drugs at each visit to last until your next visit. 
 
Other Medications 
You will continue to take all the other medication prescribed by your doctor during the study. They will be 
reviewed during the screening visit and approved if you are eligible for the study. It is extremely important to provide 
an accurate list of all your medications (prescribed, over-the-counter, and herbal) at each visit, or if there are changes 
between visits, so that we can determine if there is an interaction between any of your medications and the study 
drugs. However, we will not supply other medications. 
 
Before you begin the main part of the study… 
During screening, you will review this consent prior to any study procedures. After the consent is signed, your medical 


4 
 
history, allergies, and medications will be reviewed with a nurse. You will have laboratory tests done to help determine 
your eligibility (unless completed within the last 8 weeks). Some of the blood will be obtained to study the immune 
response to HCV, and it will be stored for possible evaluation of the HCV resistance to antiviral medications. Some labs 
will be done to evaluate your liver disease and to help determine whether HCV is the only cause  
of your liver disease. Urine testing will be done. You will have a physical examination and your weight measured and 
your medical history will be reviewed by a doctor, physician assistant or nurse practitioner.  
 
The severity of your liver disease must be documented by standard of care method prior to enrollment. This may 
involve a liver biopsy or transient elastography (FibroScan®) if you have not had o n e  p e r f o r m e d  w i t h i n  
1 2  m o n t h s . We will explain in great detail the process it involves, and the risks it may also present. You may 
have a liver ultrasound or other imaging done prior to the liver biopsy if the study doctor feels it is necessary. At the 
time of liver biopsy, you will sign another consent that will explain the procedure and risks in greater detail. 
 
During the main part of the study… 
 
Day 0 (Start of SOF/LDV) 
On this day you will have a physical examination and your vital signs will be taken. Blood will be drawn for standard of 
care labs, including blood drawn to measure the amount of HCV in your blood (HCV viral load).  Blood will also be 
drawn for HCV and immunology research purposes. If you are a female of childbearing potential, you will have a 
pregnancy test. You will then receive your first dose of SOF/LDV (which are given in one pill). You will receive teaching 
about the study drugs. 
 
Other Visits: Week 4, and 12 (+ weeks 24 for those receiving 24 weeks of treatment)  
These visits are aimed at determining how well the study drugs are reducing HCV viral load and how you are 
tolerating them. Blood tests as noted above (e.g., safety labs, viral loads, study drug levels, and immunology 
studies) will be done, and your weight will be measured at all study visits. At week 4 and week 12 or 24 (when you 
stop taking the study medication) you will have a physical exam with a medical provider in addition to having labs 
collected and potential side effects reviewed. The last dose of study medications will be taken after receiving them 
for 12 or 24 weeks.  
 
End of Treatment Visit Week 12 (or Week 24 for those receiving 24 weeks of treatment)  
 
You will have a liver biopsy performed at the end of treatment as part of standard of care. If you do not have a liver 
biopsy performed as part of standard of care, you will have liver staging performed by another method, which may 
include a FibroScan®.  
 
HCV Viral Load Results from Week 4  
By Week 4 on treatment, if you do not have a significant drop in your HCV viral load you may be discontinued 
from therapy. If you are discontinued from treatment, you will be advised of your options. If you were to continue to 
take the study drugs you would have a risk of becoming resistant to this drug or other similar drugs. If you stop 
study medications early you will continue to be seen every 12 weeks for safety monitoring and may complete the 
week 12 labs and procedures as an end of treatment visit. 
 
Other 
If you have not yet had a liver transplant when you start taking the study drug to treat your hepatitis C, we will collect 
some of the tissue from your liver when we remove it for transplant. The tissue will not be used to make clinical 
decisions about your care. The study investigators would like to see if they can detect the hepatitis C virus in the liver 
when it is removed, even if you have been treated and have an undetectable amount of hepatitis C virus in your 
blood. This is solely for research purposes. It is possible that some of this tissue will be made available to researchers 
outside of this study. If so, it will be done in a way that will not identify you.   
 
When you are finished receiving study drug (SOF/LDV)… 
 
Follow up post treatment month 3 and month 6   
You will be asked to return for blood tests, blood draw for research purposes, weight measurements, and routine clinic 
visits. During the last visit, the results of the study will be discussed with you and as your results are available someone 
from the study team will keep you up to date on the status of your HCV infection after treatment.

What side effects or risks can I expect from being in the study? 
 
You may have side effects while on the study. Everyone taking part in the study will be watched carefully for any side 
effects. However, doctors don’t know all the side effects that may happen. Side effects may be mild or serious. You 
should talk to your study doctor about any side effects you experience while taking part in the study 
 
Side Effects of SOF/LDV 
The drugs used in this study may have side effects, some of which are listed below. Please note that these lists do not 
include all the side effects, but includes the more common side effects with a known or possible relationship. If you 
have questions concerning study drug side effects please ask the medical staff at your site.  
 
There is a risk of serious and/or life-threatening side effects when non-study medications are taken with the study 
drugs. For your safety, you must tell the study doctor or nurse about all medications you are taking before you start 
the study drug and also before starting any new medications while in the study. Also, you must tell the study doctor or 
nurse before enrolling in any other clinical trials while in this study. 
 
In studies, this drug has been generally well tolerated. Risks and side effects related to SOF/LDV include: 
 
Most Common 
 
Tiredness 
 
Headache 
Less Common 
 
Nausea 
 
Diarrhea 
 
Insomnia 
 
Cardiac disorders when co-administered with amiodarone 
 
Resistance 
We do not know how effective SOF/LDV will be in eliminating HCV in people with HIV. This is one of the purposes 
of our study. One of the main risks of participating in this study is the possibility that HCV may become resistant to the 
medication and may limit your future treatment options. The likelihood of resistance developing is higher if you 
skip doses or do not follow the study recommendations. If you show possible resistance to the study drugs by having 
an increase in your HCV viral load while on treatment, you will be asked to return to repeat the HCV viral load test 
quickly, and will be taken off the SOF and LDV if the repeat test shows the same. You will still be followed for the 
study but less frequently (every 12 weeks).  
 
If you do not respond to treatment with SOF/LDV there is a potential risk of not being able to respond to other 
drugs in the same class (that are being developed) in the future. However this should not affect how you respond to 
other available treatments such as interferon, RBV and HCV protease inhibitors. 
 
HIV Virologic Rebound 
If you are on HIV medicines and during treatment your HIV viral load reaches more than 1000 copies/mL, we will ask 
you to come back to repeat the test and check for resistance to your antiretroviral drugs. If resistance is detected, 
you may be asked to switch to a different combination of HIV medicines or possibly the study doctor may ask 
you to hold off taking HIV medicines until you finish taking the HCV study drugs. 
 
Potential Risk of Kidney Problems 
In participants on HIV medicines that contain tenofovir, there is a possibility that the drug levels might be raised to 
higher than normal levels. Because of this, all participants on study will receive increased monitoring of kidney 
function. This will be done through blood and urine testing during study visits. If this would happen, a study doctor 
would explain it to you and it is possible that the dose amount of your HIV medicine may have to be adjusted or 
stopped. 
 
Liver Biopsy 
Doctors who specialize in this procedure, Interventional Radiologists, will perform the liver biopsy. The liver biopsy will 
be done as an outpatient procedure and you will need to have someone come to the procedure to accompany 


6 
 
you home. As a precaution, we will ask you to remain in the hospital for at least 6 hours after the procedure 
to be observed and evaluated for any possible complications from the procedure. We will try to make the experience 
as comfortable for you as possible. We try to make you sleepy by giving you a medication called Versed (midazolam) 
through an intravenous line (a line that goes into your vein) before the process. A numbing medication called 
Xylocaine (lidocaine hydrochloride) is injected under your skin to make the area numb before a larger needle is put 
through to do the biopsy. The medications mentioned above are safe at the doses that they will be used. However, 
in rare incidences, you may have an allergic reaction to them. The doctors who will do the liver biopsy will use an 
ultrasound scan to locate your liver and a needle to get some small pieces of your liver. However, occasionally a 
liver biopsy can cause problems such as bleeding and infection. Rarely, the biopsy needle misses the liver and can 
hit another organ and cause damage to that organ. If the problems of bleeding, infection, and organ damage are 
very serious, it may very rarely result in death. 
 
 
FibroScan® 
The FibroScan® technique will be used to measure the amount of liver fibrosis in a non-invasive and painless manner. 
Performed at the bedside in the clinic, a machine will generate a pulse wave at the skin surface, which will spread 
through the liver. The speed of the wave will be measured by ultrasound. In general, the whole examination process 
can be completed within 15 minutes. 
 
This Fibroscan will be performed by technical personnel and/or hepatologist and the results will be reported to the 
investigators. There are no potential discomforts or risks involved with the Fibroscan procedure. However, according to 
the recommendations of use and based on safety and efficacy matters; pregnant women, patients with ascites (fluid in 
the abdomen), persons with active implantable medical devices and persons with a waist size more than 100cm will be 
excluded from this procedure.  
 
Pregnancy/Birth Control 
No adequate human data are available to establish whether or not SOF/LDV poses a risk to pregnancy outcomes. 
Animal studies have not found a risk to the fetus, but there are no well-controlled studies in pregnant women. Women 
of child bearing potential must have a negative urine pregnancy test on the day study drug is started.  
 
If you become pregnant during the study, it is important that you tell us right away. You may need to stop taking the 
study drugs, but we will continue to follow you and the outcome of the pregnancy. 
 
Blood Drawing  
The potential risks of the needle stick to draw blood include pain, bruising, bleeding, fainting, and infection. 
Discomfort from this procedure is generally short lasting, and serious side effects are extremely rare. Some people 
experience feelings of lightheadedness or dizziness after having blood drawn. The amount of blood drawn will be 
within the limits allowed for adult participants. 
 
Genetic Testing 
Some of the blood drawn from you as part of this study will be used for genetic tests. Genetic tests can help 
researchers learn about potential relationships between response to HCV treatment and genetic factors. HLA 
testing may also be completed. This is a genetic test of markers of the immune system. It is usually used to match 
bone marrow or organ transplants. Some HLA types have been associated with an increased risk of certain 
diseases like arthritis and other rheumatologic problems. However, simply having those HLA types doesn’t mean 
you will develop these diseases For research, HLA testing might be used to try to identify factors associated 
with the progression of disease or related conditions. In addition, determining HLA type is necessary to be able to 
perform certain research studies. 
 
Results of HLA testing may become a part of your medical record if done outside of the study requirements, but will be 
confidential. Records containing this information will be kept on password-protected computer systems and in locked 
and secured quarters within the hospital. We will not release any information about you or your family to relatives, 
any insurance company, employer, or your primary care physician without your written permission. There may be a 
risk that genetic information obtained as a result of participation in research could be misused for discriminatory 
purposes. However, state and federal laws provide some protections against genetic discrimination. Researchers who 
will have access to genetic information about you will take measures to maintain the confidentiality of your genetic 
information.  Although we are committed to confidentiality, a court could still subpoena your medical records. All of 


7 
 
these issues should be carefully considered before joining the study. 
 
Are there benefits to taking part in the study? 
SOF/LDV (combined in one pill called Harvoni), is approved for the treatment of chronic HCV. The safety and 
efficacy of Harvoni has not been established in people with decompensated cirrhosis or in people after liver 
transplantation. The information from this study may help the researchers learn more about SOF/LDV in the 
treatment of people with HCV and HIV that are pre or post liver transplant.  It is possible that you would receive no 
benefit from the study treatment and possible that you may effectively treat your HCV and no longer have chronic 
HCV after completion of the study treatment. 
 
What other choices do you have if you do not take part in this study? 
We encourage you to discuss this study with your physician and to explore other treatment options. Other 
treatment options for chronic HCV infection include other oral combinations of medications or choosing not to pursue 
treatment of HCV at this time. 
 
Can you stop being in the study? 
Yes. You can decide to stop at any time. Tell the study doctor if you are thinking about stopping or decide to stop. He 
or she will tell you how to stop your participation safely. It is important to tell the study doctor if you are thinking 
about stopping so that your doctor can evaluate any risks and discuss what alternative follow-up care and testing 
could be most helpful for you. 
 
Reasons for Stopping Study Medications 
If you are not responding to the study medications (checked frequently by measuring the levels of HCV in your blood) 
or develop a potential life threatening complication from the medication, we will stop the study medications 
completely. However, you will still be followed but less frequently (every 12 weeks). Regardless of the stage of liver 
disease, the recommendations are to treat HCV if medically possible, however some physicians might choose to wait 
and not treat in the immediate future. 
 
Reasons for Withdrawal or Study Discontinuation 
Your involvement in this study is entirely up to you. You may leave the study at any time and for any reason. If 
you decide to leave, we may ask you to return for a final visit to perform tests and exams to ensure safety. However, 
you will not be required to return for this visit. 
 
You may be discontinued from the study (taken off the study without our asking for your permission) if: 
• 
You become pregnant while undergoing treatment with SOF/LDV. 
• 
We cannot locate you, or if you miss multiple visits or study drug doses. 
• 
You develop a condition that it is life threatening or any other significant risk as judged by the Investigator. 
• 
We or your primary care provider believe that it is in your best interest to stop taking the study medications 
even if the criteria required for stopping treatment have not been met. 
• 
Either SOF or LDV are no longer produced by the company, or if a decision is made to stop the study. 
• 
Refusal to have your samples stored will be treated as a withdrawal of consent and you will be removed from 
the study. 
 
What are the costs of taking part in this study? [Excluding NIH Clinical Center] 
The costs of all visits and tests described above will be billed to you or your insurance carrier, with the exception of 
the optional non-standard of care research biopsy, the blood draw for research purposes, and the study drug, which 
will be paid for by the study sponsor.  Insurance companies and other carriers sometimes refuse to pay the costs of 
treatment when individuals are participating in research.  If this happens in your case, you will be billed for the care 
your insurance will not cover.  Financial counselors are available through the hospital accounting department to 
discuss this with you. 
  
Will you be paid for taking part in this study? 
 
You will not be paid for participating in this study. If you are injured as a result of being in this study, CENTER NAME 
will provide necessary medical treatment.  The costs of the treatment may be billed to you or your insurer just like any 
other medical costs.  CENTER NAME and the U.S. National Institutes of Health (NIH) do not have a mechanism to 
provide compensation for research related injury.  For further information about this, you may call XXX at XXX- XXX-

What are your rights if you take part in this study? 
Taking part in this study is your choice. You may choose either to take part or not to take part in the study. If you decide 
to take part in this study, you may leave the study at any time. No matter what decision you make, there will be no 
penalty to you and you will not lose any of your regular benefits to which you are otherwise entitled.  Refusal to 
participate will not affect your legal rights or the quality of care that you may receive at this center. 
 
You will be informed by the research team if any important new findings develop during the course of the study that 
may affect your decision to continue. 
 
Who can answer your questions about the study? 
You can talk to your study doctor about any questions, concerns, or complaints you have about this study. Contact your study 
doctor(s) [name(s)] at [telephone number(s)] 
 
Stored Samples and Future Research 
If you agree to participate in this study, you also agree to let us store your samples for future research. These 
stored samples may help us learn more about HCV. We will label your stored samples with a code that only the study 
team can link to you. We will keep any information that can be traced back to you as private as possible. If you 
change your mind and decide you do not want us to store your samples, please contact us. We will do our best to 
comply with your request, but cannot guarantee that we will always be able to destroy all your samples. 
 
We might send your samples to other investigators for their research, without any information that can identify you. 
We might also share information such as your sex, age, health history, or ethnicity. We will not sell your samples and 
you will not be paid for any products that result from the research. Some future studies may need health 
information (such as smoking history or present health status) that we don’t already have. If so, our study team 
will contact you. Future research that uses your samples will probably not help you, but it may help us learn more 
about how to treat or prevent HCV and other health problems. In general, the research tests we perform are not like 
routine medical tests, and may not relate directly to your medical care. 
 
How will information about you be kept confidential? 
Your medical records will be kept confidential to the extent allowed by the law. Your name or any other data that 
might identify you will not be used in any reports or publications resulting from this study. Because of your 
consent to participate, your medical records may be reviewed by NIH staff, by the study Sponsor  and by the IRB 
(the body responsible for making sure that the study follows the guidelines for the protection of human research 
subjects) with the understanding that these records will be used only in connection with carrying out obligations 
relating to this clinical study. We will be routinely supplying information about you to your personal physician(s). You 
may change physicians whenever you like, but we need to have a physician with whom we can communicate about 
you. We would not ask your permission for each of these contacts. 
 
Conflict of Interest 
The National Institutes of Health reviews NIH staff researchers at least yearly for conflicts of interest. The following 
link contains details on this process http://ethics.od.nih.gov/procedures.htm#protocol. You may ask your research 
team for additional information or a copy of the Protocol Review Guide. 
 
This protocol may have Investigators who are not NIH employees. Non-NIH Investigators are expected to adhere to 
the principles of the Protocol Review Guide but are not required to report their personal financial holdings to the NIH.

Study Design: 
Retrospective/Prospective, open-label study using sofosbuvir based DAA 
therapy to treat HIV/HCV coinfected pre or post liver transplant 
participants   
Primary Objectives: 
1. To assess the safety, tolerability, and efficacy of sofosbuvir based DAA 
therapy for 12 - 24 weeks in HIV/HCV coinfected participants pre- and 
post-liver transplant. 
 
2.  To assess the safety, tolerability, and efficacy of a fixed dose 
combination (FDC) of sofosbuvir and ledipasvir (SOF/LDV) for 12 - 24 
weeks in HIV/HCV coinfected participants pre- and post-liver transplant 
 
 
Secondary Objectives: 
1. To evaluate changes in HCV viral kinetics with fixed dose combination (FDC) SOF/LDV or 
sofosbuvir based DAA therapies in HIV/HCV coinfected subjects with pre or post liver 
transplant HCV 
 
2. To evaluate the proportion of subjects with HCV viral loads below the level of quantification at 
various time points of the study 
 
3. To determine sustained virologic response rates with FDC SOF/LDV or sofosbuvir based DAA 
therapies.

4. To identify the determinants of response to interferon sparing therapy in eradicating HCV in pre 
or post liver transplant HIV/HCV coinfected subjects  
 
5. To identify the host genetic, protein, gene, and proteomic factors that are associated with 
responses to interferon (IFN) sparing therapy in pre or post liver transplant HIV/HCV coinfected 
subjects (prospective arm only) 
 
6. To determine if levels of interferon-stimulated genes (ISG) expression in PBMCs or liver can 
predict rapid virologic response (RVR), end treatment response (ETR), and sustained virologic 
response (SVR) in subjects receiving IFN sparing therapy (prospective arm only) 
 
7. To evaluate the proportion of subjects whose ALT normalizes during therapy and between 
baseline and SVR 
 
8. To evaluate the emergence of viral resistance during therapy with FDC SOF/LDV or sofosbuvir 
based DAA therapies.  
 
9. To evaluate change in liver fibrosis and liver function before and after treatment with FDC 
SOF/LDV or sofosbuvir based DAA therapies.

PRÉCIS 
 
Liver transplantation (LT) in HIV/HCV patients results in worse outcomes than in HCV or HIV patients 
[1-4]. Similarly, survival rates after LT are significantly lower in HIV/HCV patients than HCV patients 
[1, 2, 5, 6]. While 1- year and 3- year survival rates in HCV monoinfection are reported at 76-92% and 
72-79%, rates with HIV and HCV coinfection are reported at 67-88% and 56-62%. Spontaneous HCV 
clearance after LT is rare and reinfection with hepatitis C after liver transplantation is nearly universal. 
Post-transplant hepatitis C is a common problem in the management and survival of HIV/HCV 
coinfected patients after liver transplantation. HCV treatment is often initiated after LT to remove the 
viral antagonist prior to further disease progression or decompensation. Rates of sustained virologic 
response to treatment with interferon (IFN) and ribavirin (RBV) after liver transplantation are low 
(around 14.8%). Moreover, overlapping toxicities between antiretrovirals (ARVs) and 
interferon/ribavirin can cause toxicities in coinfected patients that require treatment cessation, ultimately 
leading to fewer patients who are able to complete treatment.  
 
Recently, several trials have confirmed the efficacy of potent direct acting antiviral (DAA) therapy 
without concomitant IFN in the treatment of HCV.  One such drug has been sofosbuvir, an NS5B 
inhibitor which in combination with IFN-based or IFN free regimens in several trials [7-9] has been 
highly effective. In HCV infected pre transplant subjects, the use of sofosbuvir and ribavirin treatment 
prior to transplantation prevented HCV recurrence in the majority of subjects who had HCV RNA 
suppressed for at least 4 weeks prior to transplant [10]. In subjects who developed recurrent hepatitis C 
post-transplant, the use of sofosbuvir and ribavirin showed promising early results with over 70% of 
subjects achieving early sustained virologic response (SVR) [11]. More recently, the use of fixed dose 
combination (FDC) sofosbuvir-ledipasvir with or without ribavirin has been shown to be effective in 
HCV monoinfected subjects including cirrhotics with SVR rates of at least 95%. [12, 13] [14, 15] Drug 
interaction studies have been completed with several HIV antiretrovirals and treatment trials of 
SOF/LDV in HIV/HCV coinfected subjects have been initiated. Hence, an ideal regimen to treat this 
difficult patient population will be an interferon-free, directly acting antiviral treatment.

INTRODUCTION 
Chronic hepatitis C virus infection is a major public health problem with an estimated 180 million 
people infected worldwide [1]. In the United States an estimated 4.1 million people are infected and is 
the principal cause of death from liver disease and leading indication for liver transplantation in the U.S 
[16-18]. Significant advances have been made with the advent of directly acting antivirals (DAA) 
against HCV over the last few years.  
 
Liver transplantation for hepatitis C and HIV coinfection has become a controversial indication for liver 
transplantation because of recently reported poor outcomes.  At the same time, the demand for liver 
transplantation in this challenging cohort of patients has been increasing, as the incidence of HCV has 
been reported to be between 23-33% in HIV infected people. Natural history studies have demonstrated 
accelerated rates of hepatic fibrosis as well as complications of cirrhosis as compared to HCV 
monoinfected people.  As a result, liver disease has now become a leading cause of death in HIV-
infected subjects.    
 
Survival rates following liver transplantation in HBV/HIV coinfected recipients are excellent and 
comparable to HBV monoinfected recipients. This is the proof that liver transplantation in the HIV 
infected recipient is safe and effective providing the coinfection can be controlled in the 
immunosuppressed HIV-infected recipient.  Unfortunately, the 1-year and 3-year survival rates are 
reported at 76-92% and 72-79% in the HCV monoinfected recipients, compared to 67-88% and 56-62% 
in HCV/HIV coinfected recipients. The poorer results in the coinfected recipients are related to 
accelerated recurrence of HCV, and higher incidence of multisystem organ failure in the presence of 
recurrent HCV. Furthermore, the accelerated pace of HCV recurrence has been exacerbated by a 
surprisingly high incidence of rejection in the HIV/HCV coinfected recipients, and the requirement for 
additional immunosuppression to reverse the rejection.  Therapy to treat HCV with interferon and 
ribavirin both pre- and post-transplant has yielded dismal results, with sustained virologic response less 
than 15%. The overall success in eliminating HCV are poor in HCV monoinfected recipients, but even 
worse in the HCV/HIV coinfected recipient as a result of overlapping toxicities between ARVs and 
interferon causing toxicities that require treatment cessation. The use of interferon-based regimens in the 
post-transplant period is further problematic based on the surprising high rejection rates observed in the 
HIV infected recipients. Furthermore, use of RBV in HIV/HCV coinfected subjects is associated with an 
increased incidence of anemia that requires dose reductions, interruptions and treatment with 
erythropoietin. All these increase the cost and adverse event profile of the therapeutic regimen, which is 
heightened in pre and post, transplant HIV-infected recipients.  Since liver transplantation uses a scarce 
resource, and results are closely monitored by regulatory agencies, many centers have stopped 
performing this procedure. Sadly, the cessation of transplanting HIV/HCV coinfected recipients is 
occurring just as potent DAA therapy is dramatically improving the safety and efficacy of anti-HCV 
therapy. The ability to safely treat HCV with interferon-free, ribavirin free directly acting antiviral 
agents with low-potential for drug interactions will be a major clinical feat that will lead to a reduction 
in the need for liver transplants, improved graft survival and improved overall morbidity and mortality 
in this challenging patient population.  
 
Recently, several trials have confirmed the efficacy of potent DAA therapy without concomitant IFN in 
the treatment of HCV.  One such drug has been sofosbuvir, an NS5B inhibitor which in combination 
with IFN-based or IFN free regimens in several trials [7-9] has been to be highly effective. In HCV 
infected pre transplant subjects, the use of sofosbuvir and ribavirin treatment prior to transplantation

prevented HCV recurrence in the majority of patients who were HCV RNA suppressed at transplant 
[10]. In subjects who developed recurrent hepatitis C post-transplant, the use of sofosbuvir and ribavirin 
showed promising early results with over 70% of subjects achieving early sustained virologic response 
(SVR) [11]. More recently, the use of FDC SOF/LDV with or without ribavirin has been shown to be 
effective in HCV monoinfected subjects including cirrhotics with SVR rates of at least 95% [12, 13] [14, 
15]. The ongoing NIAID SYNERGY trial of the FDC SOF/LDV has shown SVR4 rates of 100% in 
HCV-monoinfected subjects including cirrhotics [19]. Drug interaction studies have been completed 
with several HIV antiretrovirals and treatment trials of SOF/LDV in HIV/HCV coinfected subjects have 
been initiated. The first of such is the ongoing NIAID ERADICATE study using the FDC of SOF/LDV  
in HIV/HCV coinfected subjects on or off antiretrovirals. In this study, viral suppression occurred 
rapidly, no major toxicities or HIV breakthroughs were observed and treatment was safe and well 
tolerated. 
1.1 
RATIONALE FOR THE STUDY 
 
In the United States 4.1 million people are infected with hepatitis C virus (HCV) and 1.1 million people 
are infected with human immunodeficiency virus (HIV)[16]. It is estimated that about one third of HIV-
infected individuals are also infected with hepatitis C, likely due to shared risk factors for transmission 
[20-23]. While morbidity and mortality resulting from HIV infection has dramatically decreased over 
the past three decades due to the advent of antiretroviral (ARV) therapy, deaths related to HCV are 
substantial [24, 25]. HCV treatment in HIV/HCV coinfected individuals is associated with decreased 
rates of virologic response and is further complicated by drug interactions and high rates of toxicities 
[26, 27].  In the United States and Western world, hepatitis C is the principal cause of death from liver 
disease and the leading indication for liver transplantation and, currently, HCV-associated deaths are 
comparable to HIV-associated deaths [22]. Coinfection leads to accelerated progression of fibrosis and 
cirrhosis [28-31], increased risk of developing decompensated liver disease and increased risk for 
hepatocellular carcinoma (see table) [30, 32-34].  
 
Liver transplantation (LT) is the only viable option for patients with advanced HCV-induced cirrhosis 
and liver failure. Although historically HIV was considered a contraindication for liver transplantation, 
studies have shown good transplantation outcomes and minimal HIV-related complications in ARV 
treated patients [35]. Nevertheless, HIV infected patients are not only less likely to receive a LT than 
non-infected patients, but they are also at a higher risk of death during the waiting period prior to LT 
[36]. 
 
Liver transplantation in HIV/HCV patients results in worse outcomes than in HCV or HIV patients [1-
4]. Similarly, survival rates after LT are significantly lower in HIV/HCV patients than HCV patients [1, 
2, 5, 6]. While 1- year and 3- year survival rates in HCV monoinfection are reported at 76-92% and 72-
79%, rates with HIV and HCV coinfection are reported at 67-88% and 56-62% [1, 6, 35, 37] Recent 
studies have shown increased levels of graft loss and acute rejection [6, 35] in coinfected subjects. 
Spontaneous HCV clearance after LT is rare [35] and reinfection with hepatitis C after liver 
transplantation is nearly universal. Recurrence of HCV disease is often more severe in subjects with 
coexistent HIV infection [1, 37] Several studies have demonstrated that progression of fibrosis in post 
LT is significantly faster than the expected natural history of the disease in the normal host [35, 37, 38]. 
Resultantly, HIV/HCV patients have more fibrosing cholestatic hepatitis, fibrosis, cirrhosis, severe graft 
fibrosis and acute HCV events than HCV monoinfected patients. HCV recurrence is the leading cause of 


 
Version 3.0 
 
13

death in both groups, but is more frequent in the HIV/HCV group. In this regard, post-transplant 
hepatitis C is a common problem in the management and survival of HIV/HCV coinfected patients after 
liver transplantation. [6, 35] 
 
A second transplantation is not a realistic option for most patients, thus, HCV treatment is often initiated 
after LT to remove the viral antagonist prior to further disease progression or decompensation. In 
coinfected subjects, the durations of treatment and doses used were lower than in monoinfected subjects, 
mainly because of drug-drug interactions with the ARVs that subjects are receiving for the treatment of 
HIV [37] Rates of sustained virologic response to treatment with interferon (IFN) and ribavirin (RBV) 
after liver transplantation are similar in both groups (All 4), albeit very low (around 14.8%) However, 
overlapping toxicities between ARVs and interferon can cause toxicities in coinfected subjects that 
require treatment cessation, ultimately leading to fewer subjects who are able to complete treatment 
[37]. Graft rejection associated with the use of pro-inflammatory cytokines such as interferon alpha 
makes post-transplant treatment of hepatitis C less desirable in this patient population Hence, an ideal 
regimen to treat this patient population will be an interferon-free, directly acting antiviral treatment. 
Several studies have now demonstrated the efficacy of SOF/LDV in subjects with cirrhosis and 
SOF/RBV in transplant subjects [10-13].  SOF/LDV (HARVONI) is now approved in the US for the 
treatment of chronic hepatitis C (CHC) genotype 1 infection in adults. Safety and efficacy of SOF/LDV 
have not been established in subjects with decompensated cirrhosis. Hence, we propose to perform a 
pilot study using SOF/LDV fixed dose combination for 12 - 24 weeks to treat HIV/HCV coinfected 
subjects who are awaiting liver transplant or have received a liver transplantation and present with post-
transplant hepatitis C. This study will provide a proof of concept to eradicate chronic hepatitis C in this 
vulnerable population and alter the natural history of post-transplant hepatitis C.

Rationale for the Current Study Design 
The overarching goal of this study is to provide the transplant community with guidance on treatment 
strategies using sofosbuvir based DAA therapies in patients with HIV-HCV pre and post-liver 
transplant. The study design includes both a retrospective and a prospective component.  
 
10-20 subjects will be enrolled in the prospective arm   designed to evaluate the efficacy and safety of 
the SOF/LDV FDC tablet, for treatment durations of 12 to 24 weeks, in chronic genotypes 1, 4, 5 & 6 in 
HIV/HCV coinfected subjects with pre or post liver transplant HCV. Pre-transplant subjects will be 
treated for 12 - 24 weeks or up to the time of liver transplant (LT). Post-transplant subjects without 
cirrhosis will be treated for 12 weeks and post-transplant patients with cirrhosis will be treated for 24 
weeks. 
 
In addition, the safety and efficacy of  sofosbuvir based DAA therapies will be elucidated from 
retrospective data and contribute to this goal.  Very little is known about the long-term benefits of DAA 
therapy in the transplant candidates and recipient, and the retrospective cohort arm allows longitudinal 
follow-up of those who have been previously cured with sofosbuvir based DAA therapy to determine 
rates of reversal of decompensation, reversal of cirrhosis and improvements in graft survival. 
 
There is a significant unmet medical need for IFN-free all oral regimens for the treatment of chronic 
HCV infection in HIV/HCV coinfection patients, particularly in patients with advanced disease and 
those with post-transplant hepatitis C given the toxicity and tolerability issues associated with these 
medications, the unwillingness of many patients to be treated with PegIFN and/or RBV, as well as the 


 
Version 3.0 
 
15

substantial numbers of patients who cannot receive PegIFN and/or RBV due to contraindications 
[41].One such drug has been sofosbuvir, an NS5B inhibitor which in combination with IFN-based or 
IFN free regimens in several trials (1-3) has been shown to be highly effective. In HCV infected 
pretransplant patients, the use of sofosbuvir and ribavirin treatment prior to transplantation prevented 
HCV recurrence in the majority of patients who were HCV RNA suppressed at transplant (4). In patients 
who developed recurrent hepatitis C post-transplant, the use of sofosbuvir and ribavirin showed 
promising early results with over 70% of patients achieving sustained virologic response 4 weeks post 
treatment (SVR4). (5) FDC SOF/LDV for 12 weeks with or without ribavirin has been shown to be 
effective in HCV monoinfected patients with SVR rates of at least 95% [13-15]. Rates of SVR were 
slightly lower (86-88%) in treatment experienced patients with cirrhosis treated for 12 weeks but SVR 
increased to 100% with treatment for 24 weeks. The ongoing NIAID SYNERGY trial of the FDC 
SOF/LDV has shown SVR12 rates of 100% in HCV-monoinfected subjects including cirrhotics (8). 
Drug interaction studies have been completed with several HIV antiretrovirals and treatment trials of 
SOF/LDV in HIV/HCV coinfected subjects have been initiated. The first of such is the NIAID 
ERADICATE study using the FDC of SOF/LDV in HIV/HCV coinfected subjects on or off 
antiretrovirals. In this study, viral suppression occurred rapidly, no major toxicities or HIV 
breakthroughs were observed and treatment was safe and well tolerated. 
 
Rationale for Studying HIV/HCV Coinfected Subjects 
HIV/HCV coinfected subjects have lower rates of SVR when treated with combination therapy using 
PegIFN/RBV when compared to HCV monoinfected subjects. HIV/HCV coinfected subjects also have 
faster rates of progression and a higher likelihood of development of end stage liver disease and 
decompensated liver failure [26, 42]. DAAs that do not rely on host immune system exclusively to 
abrogate HCV replication may be an effective approach among HIV/HCV coinfected subjects regardless 
of race and IL28B genotype.  
 
Furthermore, use of RBV in HIV/HCV coinfected subjects is associated with an increased incidence of 
anemia that requires dose reductions, interruptions and or treatment with erythropoietin. All these 
increase the cost and adverse event profile of the therapeutic regimen. The development of a treatment 
regimen without PegIFN/RBV for genotype 1 patients co-infected with chronic HCV infection and HIV-
1 infection would allow for increased access to successful treatment to a significant proportion of the 
HCV-infected population. Safety, tolerability and efficacy of IFN free regimens appear comparable 
between the HIV/HCV coinfected and HCV monoinfected subjects supporting the evaluation of similar 
regimens to those under evaluation in HCV monoinfection. Furthermore, certain studies suggest that 
patients with a robust immune status respond better to HCV therapy [43].  
 
 
Overall Risk/Benefit Assessment 
The SOF/LDV FDC product combines a potent HCV nucleotide inhibitor and a potent HCV NS5A 
inhibitor, and has the potential to be a once-daily regimen for the treatment of chronic genotype 1 HCV 
infection.  
 
The potential benefits of SOF/LDV FDC product for the treatment of chronic HCV are: 
 Greater antiviral efficacy (i.e., rapid and durable eradication of HCV) compared to the current 
standard of care  


 
Version 3.0 
 
16 
7/11/2017 
 A reduction in the AEs currently associated with the use of PegIFN, RBV, and/or available 
protease inhibitors (telaprevir, boceprevir) 
 Shortened duration of therapy  
 Increased adherence to therapy with the convenience of a once daily, all oral, FDC   
 
The combination of sofosbuvir 400 mg and ledipasvir 90 mg has been administered in studies to over 
2,500 subjects.  A review of the safety data from completed studies shows that treatment with sofosbuvir 
and ledipasvir or FDC has been generally well tolerated.  No deaths or discontinuations of study drug 
due to AEs have been reported.  No Grade 4 or clinically relevant Grade 3 laboratory abnormalities have 
been reported.  No trends in vital sign changes have been observed following administration. The 
favorable safety and efficacy profiles of support further evaluation of this combination. 
 
Postmarketing cases of symptomatic bradycardia, including fatal cardiac arrest and cases requiring 
pacemaker intervention have been reported when amiodarone is coadministered with SOF/LDV FDC. 
Bradycardia has generally occurred within hours to days, but cases have been observed up to 2 weeks 
after initiating HCV treatment. Patients also taking beta blockers, or those with underlying cardiac 
comorbidities and/or advanced liver disease may be at increased risk for symptomatic bradycardia with 
coadministration of amiodarone. Bradycardia generally resolved after discontinuation of HCV treatment. 
The mechanism for this effect is unknown. Coadministration of amiodarone with SOF/LDV FDC is not 
recommended.  
  
Rationale for the use of Interferon-free, all Oral Regimen 
HIV-infected subjects seem to have lower responses to HCV treatment using interferon based regimens. 
Since HIV infection is by itself an immunoregulatory disease, it is believed that these subjects will have 
less optimal responses to immune based therapies. However, use of non-immune based directly acting 
antiviral therapies that do not rely on host immunity excessively, seem to work very well in HIV 
infected subjects. For example, HIV infected subjects respond to antiretroviral therapy regardless of 
baseline CD4 T cell counts. Hence, it is expected that HIV-infected subjects would have better rates of 
SVR when treated with non-immune based, directly acting agents for HCV. Second, we have previously 
demonstrated that HIV-infected subjects who control HIV replication by themselves without the aid of 
ART seem to have faster clearance than those subjects with similar CD4 T cell counts, but requiring 
ART to suppress HIV replication [28]. Third, we are using an extended treatment duration for these 
subjects (12 to 24 weeks). We believe this would allow us to maximize the rates of SVR for HIV 
infected pre and post liver transplant subjects in which relapse can be severe and associated with 
significant worsening of decompensation.[44]

STUDY DESCRIPTION 
Approximately fifty HIV/HCV coinfected patients with decompensated liver disease will be enrolled in 
the study. Ten (up to twenty) subjects will be treated with FDC SOF/LDV pre or post liver transplant 
and followed prospectively. Forty + subjects will be enrolled retrospectively with the intent to capture 
all patients who have been exposed to sofosbuvir based DAA therapies at participating sites since 
1/2014, and to mirror the population being enrolled prospectively.  
 
In addition, participants in the retrospective arm will be contacted to consent to one prospective study 
visit for liver staging to determine rates of reversal of decompensation, reversal of cirrhosis and 
improvements in graft survival post treatment, and for future contact by the NIH Clinical Center to 
assess longer term outcomes when this study ends.

Retrospective Arm 
Participating sites will collect clinical data on all of the HIV/HCV co-infected patients with 
decompensated liver disease (CPT >7 pre or post liver transplant) treated with sofosbuvir based DAA 
therapies since 1/2014 at their center. This will be done under IRB approved waiver of consent  if 
possible so that all treated patients meeting the inclusion criteria can be included to avoid statistical bias. 
Data collected will mirror the data collected in the prospective arm. In addition, participants will be 
contacted to provide consent to return to the site for one visit for current liver staging to evaluate 
reversal of fibrosis (unless liver staging by Fibroscan or liver biopsy was done in the previous 12 
months),  and to be contacted in the future by the NIH Clinical Center for long term follow-up. 
 
 Efficacy will be defined as HCV RNA undetectable ≥ 12 weeks post end of sofosbuvir based 
DAA therapy.  
 Safety and tolerability will be defined by  
o discontinuation rates 
o rates of hospitalization during DAA therapy 
o frequency of anemia requiring blood transfusion or EPO 
o survival. 
 Reversal of decompensation: defined by CP score and MELD score at last follow-up (evaluated 
at time to event given the variability in length of follow-up post treatment) 
 Reversal of fibrosis: defined by liver fibrosis by Fibroscan or biopsy at last follow-up (evaluated 
at time to event given the variability in length of follow-up post treatment) 
3.2 
Prospective Arm 
The cohort of pre-transplant patients with cirrhosis due to hepatitis C will be treated with SOF/LDV 
until LT or for a maximum of 24 weeks. Patients with and without HCC within Milan criteria are 
eligible. Another cohort of liver transplant recipients with recurrent HCV infection post liver transplant 
will also be treated with SOF/LDV for a period of 12 weeks (no cirrhosis) or 24 weeks (cirrhosis). 
Patients with fibrosing cholestatic hepatitis are eligible and will be treated for 12 weeks. 
 
Starting with Day 0, all subjects will receive SOF/LDV for 12 or up to 24 weeks. The total amount of 
time required to complete all the study visits is approximately 56 - 68 weeks from the screening period 
through the end of the follow-up visits:  
 
Up to 8 weeks Screening period 
 12 or 24 week treatment period  
 12 and 24 week post-treatment follow-up visits (SVR12 and SVR24) 
 36 weeks post-treatment to assess late viral relapse 
Subjects identified to have mutations leading to SOF or LDV resistance following sequencing and 
phenotypic analysis will be requested to return at 12-week intervals for up to 36 weeks to determine the 
time required for the resistant virus to return to background levels.

STATISTICAL ANALYSIS 
4.1 Sample Size Requirements 
The sample size of 50 was chosen for 3 reasons: 
 
1. This is an achievable sample size given the number of known pool of HCV/HIV coinfected liver 
transplant candidates and recipients at the participating study sites and the available time for 
recruitment. This sample size will also represent the largest experience with interferon- and 
ribavirin-free therapy in this specific population. In terms of the primary efficacy endpoint, 
combined (pre and post-transplant) and separate analyses of SVR12 will be estimated. Table 1 
shows the width of a 95% exact confidence interval for the probability of SVR12 as a function of the 
number of SVRs in a sample size of 50. For instance, if all 50 subjects have sustained virologic 
response, we can be 95% confident that the true SVR probability is between 0.929 and 1.

2. A sample size of 50 (pre and post-transplant) is sufficient to address the safety endpoints.  If the 
true event probability is 5% or more, there is about a 92% chance of observing at least one such 
adverse event (Table 2).  Consequently, if no one has a given type of AE, we can be confident that 
its true probability is under 5%. This trial will provide preliminary evidence on the safety and 
efficacy of FDC in pre or post liver transplant HIV/HCV coinfected subjects.

For AE probabilities shown in row 1, row 2 gives the probabilities of observing at least 1 
participant with the AE among 50 total participants. 
 
3. A sample size of 50 is adequate to support the mechanistic virologic and immunologic studies. 
4.1.1 Primary Endpoint 
The primary efficacy endpoint is SVR12 (HCV RNA <LLOQ 12 weeks after cessation of therapy).  
4.1.2 Secondary Endpoints 
Secondary efficacy endpoints include: HCV RNA < LLOQ at 4 and 24 weeks after discontinuation of 
therapy (SVR4 and SVR24); viral breakthrough; and relapse. 
4.1.3 Safety Endpoints 
The primary safety endpoint is any AE leading to permanent discontinuation of study drug(s).  
4.1.4 Other Endpoints of Interest 
Additional efficacy evaluations may include HCV RNA change from Day 0; ALT normalization; and 
viral kinetic parameters.

The primary analysis population for efficacy analysis will be defined as all participants who received at 
least one dose of study drug. 
 
4.2.2 Safety Population   
The primary analysis set for safety analyses will include subjects who received at least one dose of study 
drug. 


 
Version 3.0 
 
21 
7/11/2017 
On treatment data will be analyzed and defined as data collected from the first dose of study drug 
through the date of last dose of study drug plus 30 days.  
4.3 Data Handling Conventions 
Missing data can have an impact upon the interpretation of the trial data. Other than the endpoints 
discussed below, values for missing data will not be imputed.  
For the analysis of post-baseline categorical efficacy endpoints, if a data point is missing and is preceded 
and followed in time by values that are deemed successes, then the missing data point will be termed a 
success; otherwise the data point will be termed a failure. 
Any subject with missing data due to premature discontinuation of the study medication will be 
considered a failure at the time points on, or following, the date of discontinuation. If no HCV RNA 
values are obtained after the last dose of study medication, the subject will be considered a treatment 
failure for the SVR endpoints.  
Where appropriate, safety data for subjects that did not complete the study will be included in summary 
statistics. For example, 
 If a subject received study medication, the subject will be included in a summary of adverse events 
according to the treatment received; otherwise, if the subject is not dosed then they will be excluded 
from the summary. 
 If safety laboratory results for a subject are missing for any reason at a time point, the subject will be 
excluded from the calculation of summary statistics for that time point. If the subject is missing a 
pre-dose value, then the subject will be excluded from the calculation of summary statistics for the 
pre-dose value and the change from pre-dose values. 
Values for missing vital signs data will not be imputed; however, a missing Day 0 result will be replaced 
with a screening result, if available. 
4.4 Efficacy Analyses 
4.4.1 Primary Analysis 
The primary efficacy endpoint is SVR12 (HCV RNA <LLOQ 12 weeks after cessation of therapy.)  
There is no active comparator group for this study (as in most clinical trials with all oral therapies in 
these populations).  
 
In the primary efficacy analysis, an exact Clopper-Pearson 95% confidence interval will be computed 
for the SVR12 rate. 
 
The primary analysis will be performed after all enrolled subjects have been followed through 12 weeks 
post-treatment or discontinued from study. 


 
Version 3.0 
 
22 
7/11/2017 
4.4.2 Secondary Analysis 
The proportion of subjects with HCV RNA below the LLOQ over time (including SVR endpoints) will 
be presented.  
Descriptive summaries and listings will be provided for additional efficacy evaluations of the proportion 
of subjects who experience virologic failure and other endpoints of interest including ALT 
normalization, plasma HCV RNA actual values, and change from baseline. Heterogeneity among the 
study populations (pre- versus post-transplant, severity of liver disease, type of ARVs, baseline 
characteristics and others) and limited sample size will preclude us from performing extensive 
multivariate models to determine predictors of treatment success or failure.  
Exploratory regression analyses may be performed to assess the relationship between demographic, 
baseline characteristics, (including baseline viral load, genotype, age, sex, race, ethnicity, 
presence/absence of cirrhosis, baseline ALT level, prior treatment experience, response to previous 
treatment [if applicable], and BMI) and antiviral activity (as measured by HCV RNA log reduction).  
Details on efficacy analyses will be described in the statistical analysis plan. 
4.5 Safety Analysis 
Safety will be evaluated by assessment of clinical laboratory tests, physical examinations, and vital signs 
measurements at various time points during the study, as well as the documentation of AEs.

6 SCHEDULE OF VISITS AND PROCEDURES: RETROSPECTIVE ARM 
6.1 Waiver of Consent 
In order to capture all eligible candidates in the retrospective arm, data will be captured under an IRB 
approved waiver of consent if sites obtain IRB approval to do so.  
6.2 Consent for liver staging and long term follow-up 
If participants can be contacted, they will be asked if they would consent to return for one study visit for 
current liver staging unless standard of care liver staging by Fibroscan or liver biopsy has been 
performed within 12 months. Each subject will provide informed consent prior to commencement of any 
study procedures according to ICH and Code of Federal Regulations (CFR).  Each subject will be 
provided a copy of the signed informed consent form. The consent will also include approval to be 
contacted in the future by the NIH and/or co-investigators for additional longer term follow-up. 
6.3 Time-points 
Clinical data from day 0 (start of treatment), week 4, and end of treatment (week 12 or 24 depending on 
treatment duration) will be recorded in the Redcap database. Data will also be recorded at 3 months post 
treatment with DAA and again at 6 or more months post treatment with DAA. A complete list of study 
procedures to be captured is outlined in the Schedule of Events (Section 11) 
 
 
7 SCHEDULE OF VISITS AND PROCEDURES: PROSPECTIVE ARM 
Participants will be seen on each study visit at the enrolling center. A complete list of study procedures 
to be performed is in the Schedule of Events (Section 11). 
7.1 Screening (Visit 1) 
Each subject will provide informed consent prior to commencement of any study procedures according 
to ICH and Code of Federal Regulations (CFR).  Each subject will be provided a copy of the signed 
informed consent form.  
 


 
Version 3.0 
 
26 
7/11/2017 
After a subject has provided informed consent, screening evaluations will be conducted and the 
investigator and other study personnel will determine if the subject is eligible for participation in the 
study. Screening will include a review of the medical history, inclusion/exclusion criteria, concomitant 
medications, physical examination, and blood tests.  Screening tests that have been done as part of other 
studies or at an outside facility can be used if within the acceptable time frame (applicable lab tests 
within 56 days before enrollment). Some tests in the schedule of events allow the use of historic data to 
be used, such as the virology panel, HIV VL, CD4+ T-cell count, and HLA. These have been marked 
accordingly in the schedule of events. 
  
Screening procedures do not need to be repeated within the 8 week screening window unless clinically 
indicated. 
7.2 Liver Staging (Screening) 
All pre-transplant subjects must have prior standard of care liver staging consistent with F4. All post-
transplant subjects must have stage of liver disease documented within the prior year by standard of care 
liver staging methods.  
7.3 Physical Examination, including vitals signs 
All participants will have a physical visit for the final determination of protocol eligibility.  In addition, 
participants will have a physical examination performed at the following time points: Day 0, week 4, 
week 12 and (if applicable) week 24 on treatment and at 6 months post treatment visits. A targeted 
physical exam will be performed on participants as needed for AE evaluation.  
7.4 Starting SOF/LDV (Visit 2) 
The participant will be started on SOF/LDV on Visit 2 (Day 0).  For wait-listed patients, treatment start 
date should coincide with an anticipate time to transplant of at least 12 weeks (based on MELD score).  
 
Blood will be drawn for standard of care labs and for research (HCV viral loads, drug level, 
immunologic studies, and for storage). For women with childbearing potential, a urine pregnancy test 
will be done on Day 0 and must be negative prior to dosing with study agent. The Day 0 procedures are 
summarized in Schedule of Events (Section 11).  
7.5 Adverse event assessment and concomitant medications 
At each visit, participants will be asked about their state of health and use of any concomitant 
medication since screening or the previous study visit.  They will also be questioned about AEs and their 
adherence with study restrictions. In addition, participants will be seen at unscheduled visits for a grade 
3 or 4 AE or any unexpected AE (adverse event) or potential toxicity.  
7.6 Study Visits during treatment 
 
All participants will be seen on days 0, weeks 4, and week 12 EOT, (or week 24 if treated for 24 wks).  
 Weeks 4 (+/- 7 days) 
 Week 12 [and 16, 20, 24 if applicable] (+/- 10 days) 
 


 
Version 3.0 
 
27 
7/11/2017 
Plasma HCV RNA will be obtained on each visit. Subjects who fail to achieve >2 log10 HCV RNA drop 
at this time (unless >2 log drop would be below LLOQ) will be discontinued from therapy unless a 
review by the PI/Operations Committee determines otherwise. 
7.7 Week 12 or 24 Visit / End of Treatment Visit 
Week 12 or 24 will mark the last dose of SOF/LDV to be administered. In addition, if a subject’s 
participation terminates prior to end of treatment, the assessments may be performed at any end-of-
treatment visit.  
7.7.1 Liver Staging (End of Treatment):  
All subjects will have end of treatment liver staging by the same method used to stage at 
screening.  
7.8 Day of Transplant (for Pre-Transplant subjects): Liver Explant Tissue 
Subjects who receive treatment pre-transplant and achieve SVR, but who nonetheless progress to liver 
transplantation, will have a portion of the explanted liver snap frozen or placed in RNA- later on the 
day of transplant. See Laboratory Manual for processing protocol. 
7.9 Post treatment follow up visits 
After discontinuation of the study drug, subjects will be followed at post-treatment Week 12 and 24. The 
visit windows are shown below 
 Follow up visits (+/- 14 days) 
 Post treatment optional liver biopsy -7 days / +30 days (but can be done outside this window at 
the investigator’s or physician designee’s discretion). 
7.10 
Early Termination and Early Treatment Discontinuation 
Participants who elect to discontinue study drugs prior to treatment completion for medical or personal 
reasons will be given the option of being followed up at least every 12 weeks for safety and research 
labs until the end of the study. The participant should have an end of treatment visit scheduled as soon as 
possible after all therapy is discontinued. Participants with undetectable HCV RNA at the end of 
treatment should continue to follow the scheduled SVR visits following the date of their last dose of 
therapy.  
 
For the prospective arm, participants who have detectable HCV RNA at the end of treatment or who 
relapse post-treatment will be asked to return for visits to determine the persistence of any HCV 
populations with treatment-emergent substitutions conferring resistance to sofosbuvir. Samples collected 
will be used to determine the durability of response or the dynamics of any changes in resistance 
conferring mutations. The reason for any early termination should be documented. 
 
8 STUDY AGENT/INTERVENTIONS: PROSPECTIVE ARM 
8.1 Disposition and Dispensation 
Study agents will be distributed via the UCSF Investigational Pharmacy according to standard 
pharmacy procedures. 
 


 
Version 3.0 
 
28 
7/11/2017 
All drug products will be stored in a securely locked area, accessible only to authorized site personnel. 
To ensure the stability of the study drug and to ensure proper product identification, the drug product 
should not be stored in a container other than the container in which they are supplied. Consideration 
will be given to handling, preparation, and disposal through measures that minimize drug contact with 
the body. Appropriate precautions will be followed to avoid direct eye contact or exposure through 
inhalation when handling study drugs. 
8.2 Packaging and Labeling of Study Drugs 
Each bottle will be individually labeled with the patient ID number, dosing instructions, recommended 
storage conditions, the name and address of the manufacturer, Investigational Use 
Statement (“Caution: New Drug – Limited by Federal [USA] Law to Investigational Use”) and that 
the agent should be kept out of reach of children. 
8.3 Formulation of FDC SOF/LDV 
SOF/LDV fixed dose combination (FDC) tablets are orange colored, diamond-shaped, film-coated 
talets containing 400 mg of sofosbuvir and 90 mg of ledipasvir. The tablets are debossed with “GSI” 
onone side and “7985” on the other side. The SOF/LDV FDC tablets contain the following inactive 
inredients: lactose monohydrate, copovidone, microcrystalline cellulose, croscarmellose sodium, 
colloidal silicon dioxide, magnesium stearate, polyvinyl alcohol, titanium dioxide, talc, polyethylene 
glycol, FD&C yellow # 6 /sunset yellow FCF aluminum lake. 
8.4 Storage And Handling of F D C  SOF/LDV  
SOF/LDV FDC bottles should be stored at room temperature below 30°C (86°F). 
8.5 Dosage and Administration of FDC SOF/LDV 
SOF/LDV FDC tablet is to be administered once daily with or without food. Each subject must be 
given instructions to maintain approximately the same daily dosing interval between study drug doses. 
For missed dose(s) of study medication, subjects will be instructed to take the missed dose(s) of study 
medication as soon as possible during the same day.  Subjects will be cautioned never to double the 
next dose with a missed dose of study drug under any circumstances. 
8.6 Treatment of Participants  
All participants will receive 12 or up to 24 weeks of SOF/LDV. SOF/LDV will be administered as a 
single pill at dose of 400 mg and 90 mg respectively orally once a day. It can be taken with or without 
food. 
If a participant who starts treatment with study drug prior to transplant receives 4 weeks of treatment or 
less prior to transplant and has detectable HCV at time of transplant, they are eligible to receive full 
treatment post-transplant. 
If a participant who starts treatment with study drug prior to transplant has received more than 4 weeks 
of treatment prior to transplant, they are NOT eligible to receive full treatment post-transplant, 
regardless of HCV RNA level at the time of liver transplantation. Therefore, study treatment is 
discontinued at the time of transplant. 


 
Version 3.0 
 
29 
7/11/2017 
8.7 Dose Modifications/Toxicities 
Maximal suppression of HCV replication is most likely accomplished by sustained delivery of antiviral 
agents at their current recommended doses. Dose reduction, however, would compromise this goal and 
predispose to the emergence of drug-resistant viral variants.  Hence, no dose reduction will be allowed 
for SOF/LDV. If SOF/LDVis stopped due to toxicity, it must not be restarted. 
 
If treatment with study drug is interrupted for <= 5 consecutive days for reasons other than drug toxicity 
(such as discontinuation due to GFR < 30), treatment can be reinitiated and the subject can remain in the 
trial. However, if treatment is interrupted for > 5 days and/or if study drug is interrupted due to drug 
toxicity, treatment with study drug should be discontinued. 
8.8 Dose Modification for SOF/LDV 
SOF/LDV dose modifications will not be permitted. If subject meets safety or virologic criteria for 
discontinuation, the SOF/LDV will be stopped.   If a subject forgets to take the medication at the correct 
time, it may be taken later in the day; however, no more than a single dose should be taken on any 
calendar day. The subject should resume the standing dosing schedule on the next day.  Any treatment 
interruption or discontinuation will be recorded including the reason for the interruption or 
discontinuation.  
8.9 Criteria Requiring Discontinuation of SOF/LDV 
Subjects will be considered treatment failures and will discontinue SOF/LDV if they meet any of the 
following criteria while taking study drugs: 
 Plasma HCV RNA greater than LLOQ after 2 prior consecutive HCV RNA values less 
than the LLOQ 
 Greater than a 1 log10 increase in plasma HCV RNA from nadir 
 Less than a 2 log10 decline in HCV RNA after 4 weeks of treatment 
 
If any of these should occur in a subjects who is currently on study drugs, the subject should return 
within one week for a confirmatory test. If the confirmatory test also meets the same criteria, the subject 
will be considered a treatment failure and should be discontinued from therapy.  Participants will be 
referred for other treatment options. The anticipated clinical impact of discontinuation should be 
discussed in advance if possible, particularly if discontinuation is thought to pose a risk to the overall 
clinical wellbeing of the subject. Those who are discontinued will continue to follow the general study 
schedule of assessments unless unwilling to do so, in which case they may be seen at least every 12 
weeks for safety and research labs until the end of the study.  Subjects will be followed closely for 
resolution of active laboratory abnormalities or adverse events that are considered related to the study 
agents prior to starting the revised schedule. 
 
Subjects who meet any of the following laboratory criteria must stop all study medication(s): 
 Any Grade 3 or greater rash associated with constitutional symptoms 
 Any Grade 4 event assessed as possibly, probably, or definitely related to treatment with 
SOF or LDV 


 
Version 3.0 
 
30 
7/11/2017 
8.9.1 Treatment Failure Criteria After Stopping SOF/LDV  
 Have detectable HCV RNA during the post-treatment period (after having achieved HCV 
RNA <LLOQ at end of treatment). 
8.10 
HIV Virologic Rebound Criteria for Subjects on ARVs 
Subjects on ARVs who have at least 2 consecutive post-Day-0 visit plasma HIV-1 RNA levels ≥ 
1000 copies/mL (at least 2 weeks apart) will be considered to have HIV virologic rebound.  
Following an initial HIV-1 RNA result of ≥ 1000 copies/mL, subjects on ARVs will be asked to return 
to the clinic after 2 weeks for a scheduled or unscheduled blood draw for confirmation of HIV virologic 
rebound. If HIV virologic rebound is confirmed, the blood samples from this visit will be used for 
HIV-1 genotype/phenotype testing. If no resistance to the subject’s current ARV regimen is detected, the 
subject may continue on current ARV regimen.   
HCV study drug should be continued unless safety events warrant the discontinuation of these study 
drugs, as outlined in section 9.2 of the protocol. 
8.11 
Concomitant Medications 
Concomitant medications taken within 30 days of screening through 30 days following discontinuation 
of study treatment need to be recorded in the source documents. 
The medications listed in Table 2 are prohibited from 28 days prior to the Day 0 (start of treatment) visit 
through the end of treatment: 
 Concomitant use of certain medications or herbal/natural supplements (inhibitors or inducers of drug 
transporters i.e., P-gp) with study drug(s) may result in pharmacokinetic interactions resulting in 
increases or decreases in exposure of study drug(s).  Examples of representative medications which 
are prohibited from 28 days prior to Day 0 (start of treatment) through the end of treatment are listed 
below: 
 Medications for disease conditions excluded from the protocol  are not listed under this Concomitant 
Medication section and are disallowed in the study. 
Note: Since this table is likely to change over time, please review the most current package inserts 
before prescribing new drugs or modifying doses of concomitant medications.

Concomitant Drug Class: Drug Name 
Clinical Comment 
Acid Reducing Agents 
Ledipasvir solubility decreases as pH increases. Drugs that increase gastric pH are 
expected to decrease concentration of ledipasvir. 
Antacids (e.g., aluminum  and 
magnesium  hydroxide)  
It is recommended to separate antacid and HARVONI administration by 4 hours. 


 
Version 3.0 
 
31 
7/11/2017 
H2-receptor antagonistsb  (e.g., 
famotidine)  
H2-receptor antagonists may be administered simultaneously with or 12 hours apart 
from HARVONI at a dose that does not exceed doses comparable to famotidine 40 
mg twice daily.  
Proton-pump inhibitorsb (e.g., 
omeprazole)  
Proton-pump inhibitor doses comparable to omeprazole 20 mg or lower can be 
administered simultaneously with HARVONI under fasted conditions.  
Antiarrhythmics : 
digoxin 
amiodarone 
Coadministration of HARVONI with digoxin may increase  the concentration of 
digoxin. Therapeutic concentration monitoring of digoxin is recommended when 
coadministered with HARVONI. Coadministration of HARVONI with amiodarone 
may result in serious symptomatic bradycardia. The mechanism of this effect is 
unknown. Coadministration of amiodarone with HARVONI is not recommended; 
if coadministration is required, cardiac monitoring is recommended . 
Anticonvulsants:  
carbamazepine  
phenytoin  
phenobarbital  
oxcarbazepine  
Coadministration of HARVONI with carbamazepine, phenytoin, phenobarbital, or 
oxcarbazepine is expected to decrease the concentration of ledipasvir and 
sofosbuvir, leading to reduced therapeutic effect of HARVONI. Coadministration 
is not recommended.  
Antimycobacterials:  
rifabutin  
rifampinb  
rifapentine  
Coadministration of HARVONI with rifabutin or rifapentine is expected to 
decrease the concentration of ledipasvir and sofosbuvir, leading to reduced 
therapeutic effect of HARVONI. Coadministration is not recommended. 
Coadministration of HARVONI with rifampin, a P-gp inducer, is not 
recommended 
HIV Antiretrovirals 
 
efavirenz,  
emtricitabine,  
tenofovir disoproxil  
fumarate (DF)  
Monitor for tenofovir-associated adverse reactions in patients receiving HARVONI 
concomitantly with the combination of efavirenz, emtricitabine and tenofovir DF. 
Refer to VIREAD, TRUVADA, or ATRIPLA prescribing information for 
recommendations on renal monitoring.  
Regimens containing  tenofovir DF and a 
HIV protease inhibitor/ritonavir  
 
atazanavir/ritonavir + 
emtricitabine/tenofovir DFb 
 
darunavir/ritonavir + 
emtricitabine/tenofovir DFb 
 
lopinavir/ritonavir + 
emtricitabine/tenofovir DF 
The safety of increased tenofovir concentrations in the setting of HARVONI and a 
HIV protease inhibitor/ritonavir  has not been established. Consider alternative 
HCV or antiretroviral therapy to avoid  increases in tenofovir exposures. If  
coadministration is necessary, monitor for tenofovir-associated adverse  reactions. 
Refer to VIREAD or TRUVADA prescribing information for recommendations on 
renal monitoring. 
elvitegravir, cobicistat,  
emtricitabine, tenofovir  
DF  
The safety of increased tenofovir concentrations in the setting of HARVONI and 
the combination of elvitegravir,  cobicistat, emtricitabine and tenofovir DF has not 
been  established. Coadministration is not recommended.  
tipranavir/ritonavir 
Coadministration of HARVONI with tipranavir/ritonavir is expected to decrease 
the concentration of ledipasvir and sofosbuvir, leading to reduced therapeutic effect 
of HARVONI. Coadministration is not recommended.  
HCV Products:  
Simeprevirb 
  
Concentrations of ledipasvir and simeprevir are increased when simeprevir is 
coadministered with ledipasvir. Coadministration of HARVONI with simeprevir is 
not recommended.  
Herbal Supplements: 
St. John’s wort (Hypericum perforatum) 
Coadministration of HARVONI with St. John’s wort, a P-gp  inducer is not 
recommended

HMG-CoA Reductase Inhibitors 
rosuvastatin 
Coadministration of HARVONI with rosuvastatin may significantly increase the 
concentration of rosuvastatin which is associated with increased risk of myopathy, 
including rhabdomyolysis. Coadministration of HARVONI with rosuvastatin is not 
recommended.  
a.This table is not all inclusive.  
b. These interactions have been studied in healthy adults.  
 
9 EVALUATION OF SAFETY  
All enrolled subjects who have received SOF/LDV will be evaluated for safety. Safety will be assessed 
by physical examination, vital signs, hematology, and chemistries. The severity of signs, symptoms, and 
AEs will be determined by using the 2014 DAIDS Table for Grading the Severity of Adult and Pediatric 
Adverse Events, with edits made to allow for clinical center normal values. 
9.1 Follow-up of Abnormal Laboratory Test Values 
In the event of unexplained abnormal laboratory test values, the tests should be repeated as soon as 
possible and followed up until they have returned to the normal range and/or an adequate explanation of 
the abnormality is found.  If a clear explanation is established it should be recorded.  
9.2   Criteria for Premature Withdrawal and Stopping Rules  
Subjects have the right to withdraw from the study at any time for any reason.  Subjects who withdraw 
early or who are terminated from study by the Investigator will not be replaced unless they have 
received no study drugs.  In addition to the criteria for stopping subject treatment described in section 
8.9, the Investigator or designee also has the right to withdraw subjects from the study for any of the 
following: 
1. Participant’s desire to leave study. 
2. Pregnancy or breastfeeding.  
3. Participant’s non-compliance. If a subject misses 5 or more total study visits or > 3 weeks of 
study drug, the subject will be removed from the protocol by the study team. 
4. Termination of study. 
5. Development of a medical condition that in the opinion of the Investigator, it is in the subject’s 
best interest to discontinue study drug even if criteria requiring drug discontinuation have not 
been met. 
6. Request of the primary care provider or Investigator if s/he thinks the study is no longer in the 
best interest of the subject.  
7. Clinical reasons believed life threatening by the physician.  
 
 
10 ADVERSE EVENT REPORTING AND MONITORING 
10.1 
  Definitions 
 
Adverse Event (AE): Any untoward or unfavorable medical occurrence in a human subject, including 
any abnormal sign (e.g. abnormal physical exam or laboratory finding), symptom, or disease, temporally 
associated with the subject’s participation in the research, whether or not considered related to the 
research 
 


 
Version 3.0 
 
33 
7/11/2017 
Adverse Reaction (AR):  An adverse event that is caused by a drug. 
 
Suspected Adverse Reaction (SAR):  An adverse event for which there is a reasonable possibility that 
the drug caused the adverse event. ‘Reasonable possibility’ means that there is evidence to suggest a 
causal relationship between the drug and the adverse event. A suspected adverse reaction implies a 
lesser degree of certainty about causality than adverse reaction, which implies a high degree of certainty. 
 
Serious Adverse Event (SAE):  
A Serious Adverse Event is an AE that results in one or more of the following outcomes: 
 
 death 
 a life threatening (i.e., an immediate threat to life) event 
 an inpatient hospitalization or prolongation of an existing hospitalization 
 a persistent or significant incapacity or substantial disruption of the ability to conduct normal life 
functions 
 a congenital anomaly/birth defect 
 a medically important event* 
 Medical and scientific judgment should be exercised in deciding whether expedited reporting is 
appropriate in other situations, such as important medical events that may not be immediately life 
threatening or result in death or hospitalization but they may jeopardize the subject or may require 
intervention to prevent one of the other outcomes listed above. 
 
 
Unexpected Adverse Event:  An AE is unexpected if it is not listed in the package insert or is not listed 
at the specificity or severity that has been observed.  It is the responsibility of the Sponsor to make this 
determination. 
 
Serious and Unexpected Suspected Adverse Reaction (SUSAR):  A SUSAR is a Suspected Adverse 
Reaction that is both Serious and Unexpected.   
 
Unanticipated Problem (UP): Any incident, experience, or outcome that is 
1.    unexpected in terms of nature, severity, or frequency in relation to 
a. 
the research risks that are described in the IRB-approved research  
protocol and informed consent document; package insert or other study documents; and 
b.    the characteristics of the subject population being studied; and 
2.   related or possibly related to participation in the research; and 
3.   places participants or others at a greater risk of harm (including physical, psychological, economic, 
or social harm) than was previously known or recognized.  (Per the study sponsor, an adverse event with 
a serious outcome will be considered increased risk.) 
 
Unanticipated Problem That Is Not An Adverse Event (UPnonAE): An incident, experience or 
outcome that is not associated with an adverse event which meets the 3 criteria of a UP.  Examples 
include occurrences of breaches of confidentiality, accidental destruction of study records, and 
unaccounted-for study drug 
 
Protocol Deviation: 


 
Version 3.0 
 
34 
7/11/2017 
Any change, divergence, or departure from the IRB approved study procedures in a research protocol. 
Protocol deviations are designated as serious or non-serious and further characterized as: 
 Those that occur because a member of the research team deviates from the protocol. 
 Those that are identified before they occur, but cannot be prevented. 
 Those that are discovered after they occur 
 
Serious Protocol Deviation: A deviation that meets the definition of a Serious Adverse Event or 
compromises the safety, welfare or rights of subjects or others. 
 
Non-compliance: The failure to comply with applicable NIH HRPP policies, IRB requirements, or 
regulatory requirements for the protection of human subjects. Non-compliance is further characterized 
as 
1. Serious: Non-compliance that: 
a. Increases risks, or causes harm, to participants 
b. Decreases potential benefits to participants 
c. Compromises the integrity of the NIH-HRPP 
d. Invalidates the study data 
2. Continuing: Non-compliance that is recurring 
3. Minor: Non-compliance that, is neither serious nor continuing. 
10.2 
  Assessing Adverse Events 
If a diagnosis is clinically evident, the diagnosis rather than the individual signs and symptoms or lab 
abnormalities will be recorded as the AE. 
 
All grade 3 or higher AEs occurring from the time treatment starts on Day 0 and through the specified 
study follow-up period will be documented, recorded, and reported. The Investigator will evaluate all 
AEs with respect to Seriousness (criteria listed above), Severity (intensity or grade), and Causality 
(relationship to study agent and relationship to research) according to the following guidelines.  
10.3 
Severity Grading 
Severity of AEs will be graded according to the “Division Of AIDS Table For Grading The Severity Of 
Adult And Pediatric Adverse Events” (Version 2.0, November, 2014). 
Adverse Events not found in the Toxicity Table will be assessed for severity and classified into one of 
the categories below: 
 Grade 1 (Mild): Event requires minimal or no treatment and do not interfere with the participant’s 
daily activities. 
 Grade 2 (Moderate): Event results in a low level of inconvenience or concern with the 
therapeutic measures.  Moderate events may cause some interference with functioning. 
 Grade 3 (Severe): Event interrupts a subject’s usual daily activity or functioning and may require 
systemic drug therapy or other treatment.  Severe events are usually incapacitating. 
 Grade 4 (Potentially Life threatening):  Events causing inability to perform basic self-care 
functions OR Medical or operative intervention indicated to prevent permanent impairment, 
persistent disability, or death. 
 Grade 5 (Death) 


 
Version 3.0 
 
35 
7/11/2017 
10.4 
Causality Assessment 
Causality (likelihood that the event is related to the study agent) will be assessed from the 
time study dosing begins until 30 days following the last dose considering the factors listed 
under the following categories:  
 
Definitely Related 
   
 reasonable temporal relationship 
 follows a known response pattern 
 clear evidence to suggest a causal relationship 
 there is no alternative etiology 
 
Probably Related 
 
 reasonable temporal relationship 
 follows a suspected response pattern (based on similar agents) 
 no evidence of a more likely alternative etiology 
 
Possibly Related 
 
 reasonable temporal relationship 
 little evidence for a more likely alternative etiology 
 
Unlikely Related 
 
 does not have a reasonable temporal relationship  
OR 
 good evidence for a more likely alternative etiology 
 
Not Related 
 
 does not have a temporal relationship 
         
OR 
 definitely due to an alternative etiology 
 
Note:  Other factors (e.g., dechallenge, rechallenge) should also be considered for each 
causality category when appropriate. Causality assessment is based on available information 
at the time of the assessment of the AE. The Investigator may revise the causality assessment 
as additional information becomes available. 
10.5 
Reporting Procedures: Prospective Arm 
10.5.1 Adverse Events 
Throughout the study, the investigator must record all grade 3 or higher events based on the “Division 
Of AIDS Table For Grading The Severity Of Adult And Pediatric Adverse Events” (Version 2.0, 
November 2014), not present at baseline, on the appropriate Adverse Event Form within 5 business days 
of identification of the event. If an event is present at baseline, is clearly documented, and does not 
change in severity throughout the study, it does not need to be captured on an Adverse Event Form. 
However, if the event resolves, or begins to resolve, and then worsens again to a grade 3 or higher, it 
must be captured on an Adverse Event Form.  
 


 
Version 3.0 
 
36 
7/11/2017 
Within 5 business days of recognition of an adverse event, the Study Coordinator or site investigator 
will: 
 Complete an Adverse Event Form in the RedCap Database. 
 Record information on the adverse event in the participant’s medical chart. 
 Provide follow-up information when it becomes available 
 
10.5.2 Serious Adverse Events 
Deaths and immediately life threatening SAEs must be reported in the Redcap Database within 1 
business day after the site becomes aware of the event. All other SAEs must be reported within 3 
business days of site awareness.   
  
10.5.3 AE and SAE Recording/Documentation/Follow-up 
Adverse events will be collected from the time treatment starts on Day 0 through the end of the study 
follow-up period. Serious Adverse Events will be collected during the treatment phase plus 30 days. 
At each contact with the subject as outlined above, information regarding AEs will be elicited by 
appropriate questioning and examinations and will be immediately recorded on a source document. 
Source documents will include: progress notes, laboratory reports, consult notes, phone call summaries, 
survey tools and data collection tools. Source documents will be reviewed in a timely manner by the 
research team. The onset date, the end date, the severity of each reportable event, and the Investigator’s 
judgment of the AEs relationship to SOF/LDV will also be recorded. 
Adverse events will be followed at a minimum until resolution of the AE or a return to baseline 
laboratory value. SAEs that occur after the study follow-up period that are reported to and are assessed 
by the Investigator to be possibly, probably, or definitely related must be reported to the UCSF Project 
Manager and in the Redcap Database, as described above. 
10.5.4 Adverse Events and Serious Adverse Events Exempt from Reporting 
Elective hospitalizations or hospital admissions for the purpose of conduct of protocol mandated 
procedures are not to be reported as an SAE unless hospitalization is prolonged due to complications. 
10.6 
Reporting Procedures: Retrospective Arm 
Adverse event and safety monitoring is not required for the retrospective arm since the retrospective arm 
only involves data collection and elastography for those who consent. Elastography is ultrasound based 
and is without adverse events.  However, sites will be asked to record data on historical adverse events 
identified in the medical record for data analysis (hospitalizations during treatment with DAA therapy, 
anemia requiring transfusion or EPO during treatment with DAA therapy, and death) but the 
retrospective arm participants are exempt from ongoing safety monitoring.

12 MECHANISTIC STUDIES: PROSPECTIVE ARM 
 
Viral Kinetics  
Samples from  Days 0, week 4, and end of treatment (EOT) will be used to assess HCV viral load levels. 
 
HCV Virologic Studies 
Full length HCV genome pyro sequencing may be performed using the protocol as described and 
compared for variability of sequences [45]. 
 
rs12979860 (IL28B) Genetic Variant 
IL28B genetic variants have been shown to predict HCV treatment induced clearance. The IL28B assay 
is a real-time PCR assay that utilizes 5-prime nuclease activity of a thermostable polymerase and unique 
primers and SNP-specific probes to determine the genotype. Test results will not be used as inclusion or 
exclusion criteria, or to randomize subjects into treatment groups. 
 
Immune Responses to HCV and HIV 
Both humoral and cellular immunity against HCV and HIV will be estimated before and during 
treatment to assess the effect of HCV treatment on host immune response against HCV. We may also 
perform multiplex PCR assays to detect ISGs before and during treatment. 
 
HCV Genotypic and Phenotypic Resistance Monitoring 
Serum samples for genotypic and phenotypic monitoring will be collected  
 
Resistance monitoring will be completed in all subjects who received study drug and were virologic 
failures as defined.  
 
Subjects who are determined by sequencing and phenotypic analysis to have had mutations leading to 
SOF resistance will be requested to return at 12 week intervals for up to 48 weeks after the last dose of 
study drug to determine the time for the resistant virus to return to background levels.  
 
RNA Extraction from liver tissue 
In addition, this protocol will also allow for exploration of the potential of an HCV viral reservoir after 
achieving the primary endpoint of SVR12.   Subjects who receive treatment pre-transplant and achieve 
SVR, but who nonetheless progress to liver transplantation, will have a portion of the explanted liver 
snap frozen or placed in RNA- later.  Subsequently, liver RNA will be extracted and an attempt will be 
made to amplify residual HCV RNA using a protocol adapted from 
(http://www.ncbi.nlm.nih.gov/pubmed/22729600) that is sensitive to 2 copies of HCV RNA/ug of total 
liver RNA. If RNA is able to be amplified, the relevant sequences of the HCV genome will be 
determined as above.  The ability to obtain sufficient quantities of liver RNA for this analysis, given that 
the whole organ is explanted at transplant, is a unique opportunity to explore the possibility of residual 
HCV RNA after SVR in this cohort.

13 HAZARDS/DISCOMFORTS/RISKS: PROSPECTIVE ARM 
13.1 
Drugs 
 
The combination of SOF/LDV is well tolerated with minimal adverse events. The safety profile of SOF 
includes approximately 1600 chronic HCV-infected subjects that have been administered over 12 weeks 
of SOF in combination with a DAA, PEG-IFN, and/or RBV. No clinical safety issues related to SOF 
have been identified to date. The safety profile of LDV includes over 1000 chronic HCV-infected 
subjects, of whom over 700 have been administered more than 12 weeks of LDV, which was given in 
combination with other DAAs, PEG-IFN, and/or RBV. No clinical safety issues related to LDV have 
been identified to date. 
 
Furthermore, there is no expectation of significant overlapping or new, unexpected toxicities upon 
administration of SOF/LDV together as an FDC. To date, the SOF/LDV FDC ± RBV has been  
administered to over 500 HCV infected subjects in ongoing phase 2/3 trials, with over 200 subjects 
having received SOF/LDV FDC ± RBV for 12 weeks or more.  
 
Risk of bradycardia: People taking beta blockers, or who have an underlying cardiac condition or 
advanced liver disease, may be at increased risk for bradycardia when taking Harvoni or Sovaldi with 
amiodarone. 
 
Risk of Reduced Therapeutic Effect of Harvoni Due to P-gp Inducers: Rifampin and St. John’s wort are 
not recommended for use with Harvoni as they may significantly decrease ledipasvir and sofosbuvir 
plasma concentrations.  
 
Related Products Not Recommended: Harvoni is not recommended for use with other products 
containing sofosbuvir (Sovaldi). 
 
Adverse Reactions 
Most common (≥10%, all grades) adverse reactions were fatigue and headache. 
 
 
Resistance 
An additional possible risk is the development of class resistance to NS5B inhibitors and NS5A 
inhibitors. Development of such resistance could affect future therapeutic options. However all efforts 
will be made to manage the development of class specific mutations that could lead to cross resistance to 
other NS5B and NS5A inhibitors.  
13.2 
 Procedures 
13.2.1 Phlebotomy 
The primary risks of phlebotomy include occasional bleeding or bruising of the skin at the site of needle 
puncture, and the sensation of transient lightheadedness or rarely, fainting and infection. The amount of 
blood drawn will be within the limits allowed for adult subjects by the NIH CC.

14 HUMAN SUBJECT PROTECTIONS 
Participants will be fully counseled prior to entry into the study as to the potential risks of the study. 
Participants who, in the opinion of the study team, do not fully comprehend these potential risks will not 
be offered participation in the study. Participants will be monitored closely during their participation in 
the study.  
 
14.1 
Gender, Ethnicity, and Race Considerations 
Participants will not be excluded based on gender, ethnicity or race. 
 
14.2 
 Children and Pregnant Women 
This study will be limited to adults 18 aged years or older. Insufficient data are available to evaluate the 
safety and efficacy of SOF/LDV FDC in the pediatric population. No adequate human data are available 
to establish whether or not SOF/LDV FDC poses a risk to pregnancy outcomes. In animal reproduction 
studies, no evidence of adverse developmental outcomes was observed with SOF or LDV at exposures 
greater than those in humans at the recommended human dose. Any woman of child-bearing potential 
must have a negative urine pregnancy test on the first day of treatment (Visit 2/Day0) prior to receiving 
the first dose of FDC.  
 
14.3 
  HIV Testing   
Candidates without confirmed HIV infections will have HIV testing at screening. If HIV negative, they 
will be excluded from enrollment as this study is designed for HIV positive participants. 
 
 
15 BENEFITS/COMPENSATION/ALTERNATIVES 
15.1 
  Benefits 
Participants may have the benefit of suppression or eradication of hepatitis C virus. Study medications 
will be provided free of charge to all participants.   
 
There may be no benefits to participating in this study.  
15.2 
Alternatives 
Participants can receive approved hepatitis C treatment with all oral interferon-free regimen as provided 
by their insurance and ordered through their private physician or decide not to be treated at this time.   
  
16 DATA SAFETY AND MONITORING 
An internal Operations and Safety Committee will meet monthly via teleconference to review ongoing 
study progress, to address ongoing operational issues that arise during the conduct of the trial, and to 
monitor accumulating data affecting subject safety.  
 


 
Version 3.0 
 
43 
7/11/2017 
Monthly teleconferences: The Operations and Safety Committee will review accrual, adverse event 
summary reports, HCV viral load measurements and treatment response data, and data quality. 
 
Daily: The Operations and Safety Committee will be notified daily of any unexpected serious adverse 
events. Upon recognition of any safety concerns, a teleconference may be held with the Operations 
Committee to discuss the concern.   
 
The Operations Committee will consist of the following personnel: 
 
Study Personnel: 
 Peter Stock (PI, UCSF) 
 Henry Masur 
 Beverly Alston-Smith 
 Shyam Kotilil 
 Theo Heller 
 Marion Peters 
 Norah Terrault 
 Eleanor Wilson 
 Rodney Rogers 
16.1 
Specific Criteria to Pause Enrollment for Virologic/Therapeutic Failure and for 
Resistance 
16.1.1   Virologic/Therapeutic Failure Criteria to Pause Enrollment 
 Criteria 1: 5 of the first 20 participants experience treatment failure while receiving treatment   
16.2 
 If Criteria to Pause Enrollment are Met 
If criteria 1 is met, the viral kinetic, pharmacokinetic and resistance data will be reviewed with the study 
team and sponsor, and a decision will be made as to whether to continue further enrollment.  
 
Participants receiving study drugs at this time will continue receiving treatment and follow-up visits 
through Week 52.   
 
 
17 STUDY SITE MONITORING 
The study will be conducted in compliance with this protocol, International Conference on 
Harmonization (ICH) Guideline for Good Clinical Practices (GCP), and any applicable regulatory 
requirement(s). The investigator (and/or designee) will make study documents (e.g., consent forms, data 
pulls) and pertinent hospital or clinical records readily available for inspection by the local IRB and 
monitors under contract to NIAID/DAIDS. 
 
As per ICH-GCP 5.18 and 21 CFR 312.50, “clinical protocols are required to be adequately monitored 
by the study sponsor.” Monitors under contract to NIAID/will visit the clinical research site to monitor 
all aspects of the study in accordance with the appropriate regulations and the approved protocol. The 


 
Version 3.0 
 
44 
7/11/2017 
objectives of a monitoring visit will be: 1) to verify the existence of signed informed consent documents 
and documentation of the ICF process for each monitored subject; 2) to verify the prompt and accurate 
recording of all monitored data points, and prompt reporting of all SAEs; 3) to compare abstracted 
information (including CRIMSON data abstracts) with individual participants’ records and source 
documents (participants’ charts, laboratory analyses and test results, physicians’ progress notes, nurses’ 
notes, and any other relevant original subject information); and 4) to help ensure investigators’ 
compliance with the protocol.  The monitors also will inspect the clinical site regulatory files to ensure 
that regulatory requirements  and applicable guidelines (ICH-GCP) are being followed. During the 
monitoring visits, the investigator (and/or designee) and other study personnel will be available to 
discuss the study progress and monitoring visit.  
 
A specific protocol monitoring plan will be discussed with the Principal Investigator and study staff 
prior to enrollment. The plan will outline the frequency of monitoring visits based on such factors as 
study enrollment, data collection status and regulatory obligations. 
 
 
18 STORED SAMPLES AND FUTURE RESEARCH: PROSPECTIVE ARM 
Extra blood and tissue samples will be stored using a code name that only the study team can link back 
to the participants. These samples will be stored for future research. Other investigators may want to 
pursue additional research using these stored samples. If so, the study team will seek IRB approval prior 
to sharing of any samples.  After approval, the study team may send these samples to them, along with 
the coded label. Investigators will use stored samples only for research. At the completion of the 
protocol, samples and data will either be destroyed, or after IRB approval, will be transferred to another 
existing protocol. The IRB will be notified in writing of any loss or destruction of stored samples.  
 
18.1 
Research Use of Stored Human Specimens and Data 
Samples and data collected under this protocol may be used to study mechanisms involved in the 
hepatitis C treatment response among participants.  Genetic testing will be performed. 
 
 
Access to research samples will be limited using a locked freezer. Samples and data will be stored using 
codes assigned by the investigators’ designees. Data will be kept in a password-protected computer. 
Only investigators and their designees will have access to the samples and data. Samples will be stored 
and tracked utilizing the NCI FCRF Repository operated by Leidos Biomedical Research Inc.   
 
In the future, other investigators (both at NIH and outside) may wish to study these samples and/or data. 
In that case, IRB approval must be sought prior to any sharing of samples. Any clinical information 
shared about the sample with or without patient identifiers would similarly require prior IRB approval. 
The research use of stored, unlinked or unidentified samples may be exempt from the need for 
prospective IRB review and approval. Exemption requests will be submitted in writing to the NIH 
Office of Human Subjects Research, which is authorized to determine whether a research activity is 
exempt.   
 


 
Version 3.0 
 
45 
7/11/2017 
The NIH Intramural Protocol Deviation definition related loss of or destruction of samples (for example, 
due to freezer malfunction) will be followed in reporting to the IRB: The deviation compromises the 
scientific integrity of the data collected for the study. 
 
Any loss or unanticipated destruction of >25% samples (for example, due to freezer malfunction) or data 
(for example, misplacing a printout of data with identifiers) will be reported to the IRB. 
 
Additionally, participants may decide at any point not to have their samples stored. This will be treated 
as a withdrawal of the consent and in this case, the principal investigator will request destruction of all 
known remaining samples and report what was done to both the subject and to the IRB. This decision 
will affect the subject’s participation in this protocol but may not affect participations in any other 
protocols. 
 
19 DATA MANAGEMENT PLAN 
All research data and results will be collected centrally at UCSF using a Redcap data system. The 
Redcap data will be stored in a professionally managed, secure, web based, collaborative environment 
which can be made available to co-investigators if needed for analysis and review.  
 
 
 
The site Principal Investigator will be responsible for assuring that the clinical data collected is 
complete, accurate, and recorded in a timely manner.  Source documentation (the point of initial 
recording of information) should support the data collected, and must be signed and dated by the person 
recording and/or reviewing the data.  Source documents include all recordings of observations or 
notations of clinical activities, and all reports and records necessary for the evaluation and 
reconstruction of the clinical trial.  Source documents include, but are not limited to, the subject’s 
medical records, laboratory reports, biopsy reports, progress notes, pharmacy records, and any other 
similar reports or records of procedures performed during the subject’s participation in the study. 
 
All exploratory mechanistic data and stored samples will be recorded and maintained using only the 
subject’s code for identification purposes, and will be maintained by the NIH Intramural investigators.  
 
All research data will be made available to scientific collaborators and supervisors for immediate 
review, consistent with requirements of confidentiality. All research data, including the primary 
experimental results, will be retained for a minimum of 5 years to allow for analysis and repetition by 
others of published material resulting from the data.  Data management, including the decision to 
publish, will be the responsibility of the PI. After publication, all research data that form the basis of that 
communication will be made available promptly and completely to all responsible scientists seeking 
further information. Exceptions include those requests that would infringe on confidentiality of clinical 
data or if unique materials were obtained under agreements that preclude their dissemination. 
 
20 STUDY RECORDS RETENTION 
The investigator is responsible for retaining all essential documents listed in the ICH Good Clinical 
Practice Guideline.  All essential documentation for all study subjects is to be maintained by the 
investigators in a secure storage facility for a minimum of three years per NIAID policies.  These 


 
Version 3.0 
 
46 
7/11/2017 
records are also to be maintained in compliance with IRB/EC, state, and federal medical records 
retention requirements, whichever is longest. All stored records are to be kept confidential to the extent 
required by federal, state, and local law.  
 
Should the investigator wish to assign the study records to another party and/or move them to another 
location, the investigator must provide written notification of such intent to NIAID with the name of the 
person who will accept responsibility for the transferred records and/or their new location. NIAID must 
be notified in writing and written NIAID permission must be received by the site prior to destruction or 
relocation of research records. 
 
21 ANONYMITY AND CONFIDENTIALITY 
As each volunteer provides consent and is then enrolled, he or she will be allocated a unique study 
number. To ensure subject confidentiality, these numeric codes will substitute for personal identifiers on 
non-clinical research results and stored samples. The information obtained during the conduct of this 
clinical study is confidential, and disclosure to third parties other than those noted is prohibited. The 
results of the research study may be published, but participants’ names or identities will not be revealed. 
Records will remain confidential. To maintain confidentiality, the PI will keep records in locked 
cabinets and the results of tests will be coded to prevent association with subject names. It is expected 
that this data will be reported in scientific journals and scientific meetings. Confidentiality of 
participants will be maintained in all forms of reporting. Participants will be informed in general terms 
of the results as soon as practical.  
 
22 PROTOCOL REGISTRATION 
 
Prior to implementation of this protocol, and any subsequent full version amendments, each site must 
have the protocol and the protocol consent form approved, as appropriate, by their local institutional 
review board (IRB)/ethics committee (EC) and any other applicable regulatory entity (RE). Upon 
receiving final approval, sites will submit all required protocol registration documents to the DAIDS 
Protocol Registration Office (DAIDS PRO) at the Regulatory Support Center (RSC).  The DAIDS 
PRO will review the submitted protocol registration packet to ensure that all of the required documents 
have been received.   
  
  
Site-specific informed consent forms (ICFs) WILL be reviewed and approved by the DAIDS PRO and 
sites will receive an Initial Registration Notification from the DAIDS PRO that indicates successful 
completion of the protocol registration process. A copy of the Initial Registration Notification should 
be retained in the site's regulatory files. 
 
Upon receiving final IRB/EC and any other applicable RE approval(s) for an amendment, sites should 
implement the amendment immediately.  Sites are required to submit an amendment registration 
packet to the DAIDS PRO at the RSC.  The DAIDS PRO will review the submitted protocol 
registration packet to ensure that all the required documents have been received. Site-specific ICF(s) 
WILL NOT be reviewed and approved by the DAIDS PRO and sites will receive an Amendment 
Registration Notification when the DAIDS PRO receives a complete registration packet. A copy of the 
Amendment Registration Notification should be retained in the site's regulatory files.

initial and amendment registrations, refer to the current version of the DAIDS Protocol Registration 
Manual. 
 
 
23 CONSENT PROCEDURES 
No screening procedures or tests for this study will be done before the consent process is completed.  
The protocol will be discussed verbally between the participant and one of the investigators or their 
designee during the screening visit. The participant will be given ample opportunity to discuss any 
questions. The patient will then be given the consent document to read. After the participant has read 
this information, there will be further opportunity for discussion with one of the investigators. If 
protocol enrollment is then agreeable, the participant will sign the standard consent document and be 
given a copy of the signed document.  After the standard consent is signed, screening for study 
eligibility will commence.

INTRODUCTION 
 
We invite you to take part in a medical research study at the [ NAME OF CENTER]. Your study doctor(s) 
[NAMES, MD] from the [NAME OF CENTER] will explain the study to you. 
 
You are being asked to take part in this study because you are HIV positive and you were treated for hepatitis C using 
a sofosbuvir based direct acting antiviral (DAA), and you had decompensated liver disease at the time of that 
treatment. The researchers would like to learn more about how the treatment worked.  About 50 people will 
participate in this study. 
 
Why is this study being done? 
The researchers have a study that is enrolling people with HIV and hepatitis C and liver disease. The study involves 
treating patients with a sofosbuvir based DAA to treat their hepatitis C. You are being asked to participate in a separate 
arm of that study since you were already treated with a similar drug for your hepatitis C.  This will help the researchers 
learn more about long term outcomes in the treatment of hepatitis C in people with HIV who have or had liver disease. 
 
The safety, tolerability and efficacy of SOF/LDV have not been established in patients with decompensated cirrhosis 
(clinical evidence of cirrhosis such as internal bleeding, fluid in the belly, or yellowing of the eyes and skin) or after liver 
transplantation. The purpose of this study is to determine whether SOF/LDV in combination for 12 to 24 weeks can be 
safe, tolerated and effective for treating HCV infection before or after liver transplantation in people who also have HIV 
infection. This drug works by blocking the HCV from dividing in your body. 
 
What will happen if sign this form? 
 
When you sign this form, you are giving consent for three things:  
 
 
The investigators will take information from your [site name] medical records and enter the data into a 
database.  This information will be kept indefinitely, unless you withdraw your permission. It will be anonymous 
and confidential. The data collection will end by December of 2018. 
 
You will be asked if you agree to allow the investigators and collaborators to contact you in the future once this 
short study is over, so they may obtain even longer follow-up data on how your hepatitis and liver are doing. 
 
Finally, if you agree, you will return to [site name] for a Fibroscan so that the researchers can see how your 
liver is doing now. If you have had liver staging by Fibroscan or liver biopsy within the previous 12 months, we 
will record the results and you would not need to return for a Fibroscan. 
 
Declining to participate will have no influence on your present or future status as a patient in this clinic. You will receive 
the same care as any other patient seen in this clinic. There will be no penalty or loss of benefits to which you are

otherwise entitled.  
 
Are there any risks to me or my privacy? 
We will do our best to protect the information we collect from you.  Information that identifies you will be kept secure.  
The data collected will not include details that directly identify you, such as your name or address.  If this study is 
published or presented at scientific meetings, names and other information that might identify you will not be used. 
 
Participation in research may involve some loss of privacy. However, your records will be handled as confidentially as 
possible. Access will be limited to the research team at [site name] and the doctor organizing the study. Your contact 
information will not be shared with anyone outside this clinic. 
 
If you agree to come in for a FibroScan®: The FibroScan® technique will be used to measure the amount of liver fibrosis 
in a non-invasive and painless manner. Performed at the bedside in the clinic, a machine will generate a pulse wave at 
the skin surface, which will spread through the liver. The speed of the wave will be measured by ultrasound. In general, 
the whole examination process can be completed within 15 minutes. 
 
This Fibroscan® will be performed by technical personnel and/or hepatologist and the results will be reported to the 
investigators. There are no potential discomforts or risks involved with the Fibroscan procedure. However, according to 
the recommendations of use and based on safety and efficacy matters, pregnant women, patients with ascites (fluid in 
the abdomen), persons with active implantable medical devices and persons with a waist size more than 100cm will be 
excluded from this procedure.  
 
Are there benefits to taking part in the study? 
 
There is no direct benefit to you. However, the information from this study may help the researchers learn more about 
sofosbuvir based DAA therapy in the treatment of people with HCV and HIV that are pre or post liver transplant.   
 
What other choices do you have if you do not take part in this study? 
We encourage you to discuss this study with your physician and to explore other treatment options. Other 
treatment options for chronic HCV infection include other oral combinations of medications or choosing not to pursue 
treatment of HCV at this time. 
 
Are there financial considerations? 
There will be no cost or payment to you if you sign this form. 
 
How will information about you be kept confidential? 
Your medical records will be kept confidential to the extent allowed by the law. Your name or any other data that 
might identify you will not be used in any reports or publications resulting from this study. Because of your 
consent to participate, your medical records may be reviewed by NIH staff, by the study Sponsor and by the IRB (the 
body responsible for making sure that the study follows the guidelines for the protection of human research 
subjects) with the understanding that these records will be used only in connection with carrying out obligations 
relating to this clinical study. We will be routinely supplying information about you to your personal physician(s). You 
may change physicians whenever you like, but we need to have a physician with whom we can communicate about 
you. We would not ask your permission for each of these contacts. 
 
 
 
What do I do if I have questions, now or later?   
You can talk with the study researcher about any questions, concerns or complaints you have about this study.  Contact 
the study researcher(s) __________________ [name(s)] at __________________ [telephone number(s)].
