Brief Summary of Protocol:
The reason for doing this research is to determine the safety and tolerability of 3 infusions (the introduction of fluid into a vein) over 2 weeks of the experimental study drug KD-247 in HIV-1 seropositive (infected) individuals.

We also want to know how much of the drug gets into your bloodstream and what effect KD-247 has on plasma HIV-1 RNA load (amount of virus in your blood, also called ‘viral load’) and on CD4+ T cell counts (CD4+ count measures the number of a type of white blood cell in the body that fights infection).

Detailed Description of Protocol:
Your participation in the study will last approximately 17 weeks, which includes a minimum 3 weeks between screening and baseline, 2 weeks of weekly KD-247 or placebo intravenous (IV) infusions given on three occasions 1 week apart, and a 12-week follow-up period.

At the time you get infusions of KD-247 there will be pharmacokinetic studies done. Pharmacokinetic (PK) means determining how much study drug is getting into your blood. PK blood samples will be collected (drawn from an IV that is placed in a vein in your arm) at the following times

Day 1 and 15: pre-dose, 30 minutes, and 1 hr, 2 hrs, 3 hrs, 6hrs, and 24 hours from start of dose infusion.

On Day 8 (infusion #2) blood samples for PK will be collected at pre-dose, 2 hrs and 24 hrs from start of dose infusion.

On Days 17 and 18 (48 hrs and 72 hours after Day 15 treatment [infusion #3]), a single blood sample will be collected. You will also have one PK sample collected at each visit for Week 3, Week 4, Week 7, Week 10 and Week 14 (1, 2, 5, 8 and 12 weeks after the last infusion, respectively).

The study consists of 15 visits. Profile:
If you join the research study, you will take part for about 17 weeks. The research study as a whole will last about 1 year.

About 36 people will take part in the research study. About 6 participants will be recruited at this site.
