Background 
 
The prevalence of nonalcoholic fatty liver disease (NAFLD) is not well defined in 
U.S. adults with HIV infection in the current era. Chronic liver disease is a major 
cause of morbidity and mortality among individuals with HIV infection (1, 2). 
With the availability of effective therapies for hepatitis B and C, NAFLD is 
predicted to become the leading cause of liver disease in the aging HIV 
population (3).  In the non-HIV population, NAFLD is associated with a) 
increased overall and liver-related mortality (4); b) increased risk for 
cardiovascular disease and type 2 diabetes (5-9); and c) increased risk for liver 
cancer even in absence of cirrhosis or significant fibrosis (10-14).  In HIV 
infected patients, the prevalence of NAFLD has not been well established. 
Reported prevalence has varied by study inclusion criteria and modality of NAFLD 
diagnosis, ranging from 15-54% when assessed by imaging modalities (15-17) 
and up to 73% in studies including liver biopsy (18).  These studies suffered 
several limitations, including the inclusion of only a small number of HIV infected 
individuals (18, 19), inclusion of patients with concurrent hepatitis C infection 
(20-23) or limiting the HIV population assessed to only military personnel and 
their dependents or to men alone (15, 16).  
 
The risk factors for NAFLD and NASH in HIV infected individuals have not been 
examined in depth. First, traditional risk factors for NAFLD in the general 
population may not apply to NAFLD in those with HIV infection. While most 
studies suggest an influence of insulin resistance, obesity and dyslipidemia on 
the risk of NAFLD in HIV infected individuals, this may not apply to male HIV 
patients who tend to be more physically fit, have similar or lower BMI and lower 
incidence of fatty liver compared to controls (16, 35, 40). Thus, it is essential to 
comprehensively evaluate NAFLD and NASH in both women and men with HIV 
infection and stratify by the metabolic syndrome and BMI to accurately 
determine prevalence in different risk groups.   
 
The impact of novel antiretroviral agents on risk for NAFLD and NASH has not 
been comprehensively evaluated. Some antiretroviral agents, particularly 
nucleoside or nucleotide reverse transcriptase inhibitors (NRTI) and protease 
inhibitors (PI), impair autophagy and mitochondrial function leading to 
lipodystrophy, insulin resistance, steatosis and steatohepatitis. (38, 41-46). There 
are, however, conflicting data from clinical studies on the contribution of ART to 
this risk and the impact of new antiretroviral agents with better metabolic 
profiles, such as integrase inhibitors, on the risk of NAFLD (15, 18, 20, 35, 47, 
48).  
 
Safe and effective therapies for NASH in HIV infected individuals are absent. 
Over the last decade, there have been several large randomized clinical trials 
(with more than a hundred ongoing Phase 2 and Phase 3 currently registered on 
Clinicaltrials.gov) to treat NASH in the general population, but the majority of 
them systematically excluded HIV infected individuals (74). Weight loss, exercise 
and therapy with vitamin E or pioglitazone have shown efficacy in improving 
NASH and are recommended for HIV uninfected patients with NASH (75). 
However, whether these measures will be effective in HIV infected individuals 
with NASH is unknown. A pilot study showed that in patients with HIV and

abdominal adiposity on stable ART, Tesamorelin, a growth hormone–releasing 
hormone analog, resulted in reduction of visceral and liver fat (76). Whether this 
expensive agent will be useful to treat NASH in HIV infected patients has not 
been established. Vitamin E is an attractive and inexpensive therapy for NASH in 
HIV infected individuals. Oxidative stress contributes to the progression of NASH 
(77-82). Based on its known function as an antioxidant (83), we and others 
have studied vitamin E used alone or with other compounds in multiple trials to 
treat NASH or NAFLD in the non-HIV population (84-93). Variable dosages 
ranging from 100-1200 IU/daily have been used with reported beneficial effects 
on liver enzymes, steatosis, inflammation, ballooning, and hepatic fibrosis. 
Duration of vitamin E monotherapy in these trials ranged from 4 to 96 weeks 
(92, 94). Vitamin E can decrease ALT levels in as early as 4 weeks (92) and 
improve histology in 6 months (87, 88). In the largest randomized trial, PIVENS 
(90), vitamin E was given at a dose of 800 IU/daily for 96 weeks and compared 
to pioglitazone or placebo. Vitamin E and pioglitazone improved ALT, steatosis, 
lobular inflammation, and ballooning and resulted in resolution of NASH in many 
patients. Vitamin E, however, was not associated with weight gain as was 
pioglitazone. Of note, low vitamin E levels were found in 7% of HIV infected men 
in one study (95), and certain ART regimens have been associated with lower 
vitamin E levels (96). Earlier small studies suggested potential reduction in 
oxidative stress and HIV viral loads and increased viability of circulating 
lymphocytes with vitamin E supplementation (97, 98). Thus, there is a strong 
rationale to investigate vitamin E as a therapy for NASH in the HIV infected 
individuals. 
 
Vitamin E for NASH in the non-HIV infected population: The efficacy of vitamin E 
for NASH was best established with the PIVENS study, one of the largest 
randomized trials in NASH to date (90). Indiana University was a major 
participating center in this study. Vitamin E was given at dose of 800 IU/daily for 
96 weeks and compared to pioglitazone or placebo. Vitamin E and pioglitazone 
improved ALT, steatosis, lobular inflammation, and ballooning and resulted in 
resolution of NASH in a significant number of patients (Figure.4). Vitamin E has 
not been tested previously as a therapy for NASH in HIV infected individuals.

Rationale and Specific Aims 
 
The aim of this study is to conduct a proof-of-concept clinical trial to evaluate the 
efficacy of vitamin E for treatment of NASH in HIV infected individuals.   
 
This project is a proof-of-concept, randomized controlled trial to test the 
hypothesis that vitamin E improves hepatic steatosis and markers of hepatic 
necroinflammation in HIV infected individuals with biopsy-proven NASH. In this 
placebo-controlled, double-blind, randomized pilot clinical trial we will randomize 
56 eligible participants at two different sites to receive 800 IU/daily of vitamin E 
or matching placebo for 6 months. The primary endpoint is the change in hepatic 
fat content from baseline to end of treatment in the two groups.  Subjects will 
undergo MR imaging to measure hepatic fat content using MR-PDFF at baseline 
and at the end of treatment. In the randomization visit, all participants will 
receive standard recommendations about lifestyle modifications including healthy

dieting, exercise, and weight loss, and use of alcohol and dietary and herbal 
supplements. 
 
 
Vitamin E is a well-established therapy for NASH in the non-HIV population (see 
section B.5 in Significance). While variable dosages ranging from 100-1200 
IU/daily have been used with reported beneficial effects on liver enzymes and 
histology, including steatosis, the dose chosen in this trial is the same used in 
PIVENS, the largest randomized clinical trial establishing the efficacy of vitamin E 
(90) and is the dose recommended by the multi-society guidelines for treatment 
of NASH in the non-HIV population (75). As vitamin E effects on ALT could be seen 
in as early as 4 weeks (92) and on histology in 6 months (87, 88), we believe the 
6 month duration of the proposed proof-of-principle study is rational. Further, 
there is emerging data to suggest low vitamin E level may be seen is small subset 
(7%) of HIV infected men (95) and in association with use of certain ART (96). 
Benefits reported with vitamin E use in the HIV infected patient in earlier small 
studies include reduction in oxidative stress and HIV viral load and increased 
viability of circulating lymphocytes with (97, 98). Finally, vitamin E is relatively 
inexpensive and has no interactions with any ART drugs. Thus, there is a strong 
rationale to investigate vitamin E as a therapy for NASH in the HIV infected 
individuals. 
 
A total of 56 subjects at two sites will be enrolled in this trial, with approximately 
28 individuals included at IU and 28 at Massachusetts General Hospital.  Subjects 
will be randomly assigned to either Group A or Group B. 
 
Group A:  Vitamin E (RRR alpha-tocopherol) 800 IU/daily for 24 weeks.  
Group B: Matching placebo for 24 weeks.

800 IU/d for 6 months (n = 28) or Group B:  matching placebo for 6 months (n = 28). 
We will use a stratified randomization plan based on one factor, diabetes, similar to the 
recent FLINT trial (142). This will ensure two treatment groups having similar 
distribution of diabetes. A stratum specific computer-generated randomization list will be 
prepared by the study statistician to randomly assign study subjects in one of the two 
treatment groups. A block size of four will be used to ensure balance in number of 
subjects recruited in the two groups.   Participants will be given sufficient drug for daily 
dosing and will be given detailed instructions about how to take the medicine.

IRB study number 1807274844                                                       10 
 
Risks of blood draw include pain and bruising at the site.  Blood will be drawn by 
experienced personnel. 
 
Risks of completing the questionnaires include embarrassment or being uncomfortable 
with the questions asked.  Subjects can refuse to answer any questions to which they do 
not wish to respond. 
 
Risks of transient elastography include being uncomfortable lying supine pain, soreness 
at the site and a small chance of allergic reaction to the ultrasound gel. These study 
procedures will be performed by experienced personnel. 
 
Risks of MRI include being uncomfortable lying still for a period of time and experiencing 
claustrophobia (feeling closed in or trapped). 
 
Risks of taking Vitamin E include allergic skin reactions (inflammation or itching), blurred 
vision, changes in cholesterol levels, changes in insulin resistance, diarrhea, dizziness, 
fatigue, flu-like symptoms, headache, heart conditions, increased risk of death, 
increased risk of fainting or falls, increased risk of heart failure, increased risk of high 
blood pressure in pregnancy, increased risk of stroke, increased risk of tuberculosis, 
kidney dysfunction, nausea, severe response to infection (in preterm babies), sexual 
dysfunction, stomach pain, vision loss, and weakness. 
 
There is a risk of loss of confidentiality. 
 
A Data Safety and Monitoring Board (DSMB) will be organized and instituted to review 
study and safety data as well as reporting adverse events/unanticipated problems and 
will meet as necessary for a thorough review of this study. The DSMB will consist of a 
hepatologist, an infectious disease specialist, and a biostatistician.

Study Withdrawal/Discontinuation 
 
It is anticipated that this study will be completed within the time frame proposed and 
that it will establish that vitamin E is beneficial in HIV infected patients with NASH. If 
vitamin E is found to exert beneficial effects on hepatic fat content and markers of 
NASH, it will justify undertaking larger multicenter randomized trials with histological 
end points to evaluate the efficacy and safety of vitamin E in this population.  
 
Inability to meet target enrollment in a timely fashion is always a concern for any clinical 
trial.  However, the sample size is realistic and enrollment is spread across several 
funding years and at two leading liver centers. People with cirrhosis have been excluded 
from this trial, as hepatic fat usually diminishes or disappears with progression to 
cirrhosis and will likely be difficult to measure at baseline in these patients. To minimize 
observer variability, MR-PDFF images will be centrally read by the study radiologist. 
Although concerns have emerged about increased risk for prostate cancer with vitamin E 
use in healthy men (144), this should be less of concern in HIV infected men who are at 
lower risk for prostate cancer than non-HIV infected men, possibly due to hypogonadism 
(145). Assuming 10% drop out rate with the clinical trial, about ten percent more 
subjects than needed to get the statistical power to evaluate the primary outcome will 
be recruited.

Because host genetic factors contribute to the response to therapy, pre-therapy baseline 
liver expression profiles will be studied to identify expression signature that predict 
response to vitamin E therapy. This approach has been used in other liver disease such 
as hepatitis C. For example, in one study, pre-treatment peripheral blood monocytes 
gene expression signature predicted response to hepatitis C therapy with 94% accuracy 
(143).  
 
Quantitative global gene expression analysis on fresh frozen liver tissue from subjects 
participating in the clinical trial will be performed.  Based on prior experience, it is 
expected to have a portion of the liver biopsy snap frozen and available for expression 
analysis on a sizable proportion of the subjects (>50%) undergoing liver biopsies as part 
of Specific Aim 2 who are the primary source for the proposed clinical trial. As such, 
HumanHT-12 v4 Expression BeadChip will be used for this aim. This chip provides 
genome-wide transcriptional coverage of well-characterized genes and their splice 
variants, and targets more than 47,000 probes derived from the NCBI RefSeq Release 
38 (November 7, 2009) and other sources.  
 
After detectable transcripts are identified, expression data will be standardized. The t- 
test statistic will be utilized to measure the expression difference between the sample 
means (responders vs. non-responders) in units of the standard deviation for which the 
difference can be tested using certain p value. For this, a significance cut-point of 
p<0.001 will be used. Then hierarchical clustering and gene network and pathway 
analysis will be performed to identify those predicting response to vitamin E therapy. A 
logistic multivariate-based analysis will be used to build up a receiver operating 
characteristic (ROC) curve, and the area under the ROC curve (AUC) will be calculated 
to assess the average sensitivity of the biomarker in discriminating the responders and 
non-responders.  
 
All endpoints are measured as the change from baseline to 24 weeks. The primary 
outcome measure is the change in hepatic fat content as measured by central reading of 
MR-PDFF performed at baseline and end of study. Secondary endpoints will be changes 
in inflammatory markers (liver enzymes, TNF-alpha, IL-10 levels), serum K-18, Liver 
stiffness and CAP measurement by TE, and MDA level as a marker of oxidative stress. 
 
The primary outcome is the improvement in liver fat as assessed by MR-PDFF at end of 
treatment compared to baseline. To our knowledge, there are no data on studying the 
effect of vitamin E on MR-PDFF in NASH patients with HIV. Using an alpha of 5% and a 
two-sample independent t-test and equal variance assumption, a sample size of 25 per 
group will have 91% power to detect an effect size of 0.97 and will have 80% power to 
detect an effect size as small as 0.81. To ensure this number is achieved, 28 subjects per 
group will be recruited, allowing for 10% drop-out during the trial. The primary purpose 
of this pilot study is to generate preliminary data to estimate the mean and variability of 
improvement in liver fat with vitamin E in HIV infected patients with NASH.  
 
Primary outcomes analysis: The primary analysis will be based on an analysis of covariance 
(ANCOVA) to compare the improvement in liver fat due to vitamin E relative to placebo. 
The model will include one dummy variable for treatment group indicator as well as 
baseline demographic characteristics and baseline liver fat.  The 95% confidence intervals 
for the difference between the two treatment groups will be reported.   
 

Vitamin E for NASH Treatment in HIV Infected Individuals 
 
Protocol date:  September 2, 2020 
IRB study number 1807274844                                                       12 
 
Secondary outcomes analysis: Secondary efficacy end points are continuous and as such 
the ANCOVA model will be used as described for analyzing the primary outcome except 
that the model will include the baseline value of the response variable.
