- Title:
A Ph I/IIa Rand Placebo Ctrl, S-Blind Multictr Dose-Esc Study of SC Intermittent Interleukin-7 CYT107 in Chronically HIV-Infected Pts with CD4 T Lymphocyte Counts 101-400 Cells-/mm(3) and Plasma HIV RNA Less Than 50 copies/mL After at Least 12 M of HAART
- Number:
07-I-0155
- Summary:
This study will evaluate the safety of a new experimental drug, IL-7, in people with HIV infection. Animal studies have shown that IL-7 can improve the function and number of infection-fighting cells called T lymphocytes, or T cells. If this study shows that IL-7 is safe, additional studies will be done to see if it can improve the function or numbers of T-cells in HIV-infected persons.
HIV-infected pesrons who have been receiving HAART therapy for at least 12 months before enrolling in the study and have been stable on this treatment for at least 3 months before enrollment may be eligible for this study.
Participants have about 10 clinic visits over 3 months. They receive three injections of IL-7, one injection a week for 3 consecutive weeks. The injections are given as a shot under the skin in the arm or leg. On the day of each injection, the participant stays in the clinic for up to 8 hours or longer for observation and collection of blood samples. Three additional visits (one every 3 months) may be scheduled.
During the study visits the following may be done:
-Medical history, physical examination, blood tests every visit.
-Electrocardiogram (EKG) at study days 0 (day of first dose), 1, 7 (day of second dose), 14 (day of third dose) and 21.
-Chest x-ray study on day 21.
-Blood sample collections at frequent intervals during the first 96 hours after the first dose administration. A catheter (thin plastic tube) is put into a vein in the arm and left in place to allow several blood samples to be drawn without repeated needle sticks.
-Urine tests several times during the study.
