Diabetic Retinopathy in HIV Subjects Treated With EGRIFTA®

To date, EGRIFTA® has not been studied for longer than 1 year in human subjects, nor has
EGRIFTA® been studied in Type 2 diabetic HIV-infected subjects who are receiving oral
hypoglycemic agents, GLP-1 analogues, or insulin. The present study will assess the potential
of EGRIFTA® to induce or exacerbate DR in HIV-infected subjects on antiretroviral therapy who
have concomitant abdominal lipohypertrophy and T2DM, and explore the long-term effects of
EGRIFTA® on glycemic control and major adverse cardiovascular event (MACE) in this
population.

Inclusion criteria:

1. Subject has given written informed consent and is willing to comply with the
requirements of the protocol;

2. Subject is an adult man or woman (≥ 18 years old);

5. Subject has physical evidence of abdominal lipohypertrophy, as determined by the
examining study physician;

6. Subject has T2DM as determined by previous HbA1c ≥ 6.5%, previous fasting plasma
glucose

- ≥ 126 mg/dL (7.0 mmol/L), and/or previous 2-hour plasma glucose ≥ 200 mg/dL (11.1
mmol/L) during oral glucose tolerance testing (OGTT), and/or previous random
plasma glucose ≥ 200 mg/dL (11.1 mmol/L) with symptoms of uncontrolled DM;

- if subject has been diagnosed with T2DM and is on glucose lowering medications
for greater than 1 year the above glucose parameters do not apply;

7. Subject, at the time of screening, has HbA1c between 6.0% and 12.0%;

8. Subject's diabetes has been treated for at least 1 year by diet alone, individuals who
are on a stable dose (at least 3 months) of insulin, an OHA, or a GLP-1 analogue plus
insulin to control diabetes are permitted if their HbA1C is below 6.0%. OHA, GLP-1
analogue, or OHA/GLP-1 analogue plus insulin according to current American Diabetes
Association (ADA) guidelines, and doses have been stable for at least 3 months;

9. If the subject is using lipid lowering drugs, the dose must be stable for at least 2
months prior to screening;

abnormalities within 6 months prior to screening;

11. Pre-menopausal women of childbearing potential are eligible only if they are not
pregnant (negative urine pregnancy tests at screening and baseline) or lactating and
are using an acceptable form of birth control prior to study entry and for at least 2
months after completing treatment. Acceptable contraception is defined as two barrier
methods, or one barrier method with a spermicide, or an intrauterine device, or an
oral contraceptive;

12. Women of non-childbearing potential must be post-menopausal (no menses for more than 1
year) or surgically sterile (tubal ligation or hysterectomy);

13. Women over 40 years old must have a negative mammogram within 6 months prior to
screening or a mammogram will be taken at screening;

14. Men must have a normal prostate exam and a prostate specific antigen (PSA) Individuals
who are on a stable dose (at least 3 months) of insulin, less than or equal to 5 ng/mL
within 6 months prior to screening or PSA and, for men 50 years of age or older, a
prostate specific antigen will be measured at screening

Exclusion Criteria:

1. Subject has Type 1 DM;

2. Subject has body mass index (BMI) < 18.5 kg.m2;

3. Subject has or has had an opportunistic infection or acquired immune deficiency
syndrome (AIDS)-defining illness within 3 months of screening;

4. Subject has or has had a malignancy or, for women, personal or family (first degree
relative) history of breast cancer. Exceptions are basal cell carcinoma, in situ
carcinoma of the cervix, in situ anal carcinoma, treated and stable cutaneous squamous
cell carcinoma. and stable Kaposi's sarcoma;

5. Pre-existing PDR or severe non-PDR (NPDR), defined as an ETDRS level of ≥ 53 in either
eye;

6. Subject has or has had cytomegalovirus (CMV) retinitis, toxoplasmosis, or any other
ocular infection that would prevent evaluation of DR;

7. Subject has previously been treated for DR (treatments such as laser photocoagulation,
intravitreal injection, or vitrectomy);

8. Subject has any of the following illnesses or conditions:

1. hypopituitarism, history of pituitary tumor or pituitary surgery;

2. untreated hypothyroidism;

3. head irradiation or head trauma that has affected the somatotropic axis;

4. uncontrolled hypertension, defined as systolic pressure > 140 mm Hg and diastolic
pressure > 90 mm Hg;

5. unstable CV condition, defined as:

i. acute MI; ii. unstable angina; iii. decompensated congestive heart failure (CHF,
new onset or exacerbation); iv. stroke; v. history of any of the above within 6 months
prior to screening; f. hepatic abnormality, defined as aspartate aminotransferase
(AST) or alanine aminotransferase (ALT) > 3 times the upper limit of normal (3 x ULN);
g. renal abnormality, defined as serum creatinine > 2 x ULN; h. lipid metabolism
abnormality, defined as fasting triglycerides > 1500 mg/dL; i. anemia, defined as
hemoglobin ≤ 7 g/dL;

9. Drug or hormone use as follows

1. Men: change in regimen or supraphysiological dose of testosterone within 2 months
prior to screening;

screening;
