Certain patients who are participating in NIH protocols involving interleukin-2 (IL-2) therapy for HIV disease may be requested to have the following changes or additions to their study protocol:
- 3-day subcutaneous (sc) IL-2 administration: Patients currently receiving IL-2 intravenously (injections through a vein) may switch to subcutaneous administration (injections under the skin). Injections are given twice a day for 3 to 5 days (one treatment cycle), with cycles repeated no more often than every 8 weeks.
- Home treatment of sc IL-2: Home administration of IL-2 injections involves less frequent data and safety monitoring and no medical evaluations at the Clinical Center except at the beginning of each cycle. Participants will receive IL-2 cycles on the same schedule they followed in their original protocol. They will be seen at the Clinical Center at regularly scheduled follow-up visits between cycles and for a medical evaluation and blood drawing before the start of each cycle to determine the safety of administering the next cycle. During the home cycle, the patient's case manager or other team member will place monitoring telephone calls on days 2 and 4 of the cycle and again a week later. The timing and number of these calls may change depending on the findings of ongoing assessments of their usefulness. Patients will be required to notify the study team promptly of complications or other problems that develop with therapy.
- Stored specimens and HLA testing: Stored blood and tissue samples from patients will be used for future research on HIV, AIDS and related medical conditions, and the immune system. The samples may be labeled with no identifying information, with identifying information, such as the patient's name, or with a code that only the study team can link to the patient. Some of the blood drawn may be used for HLA typing, a genetic test of markers of the immune system. Usually used to match bone marrow or organ transplants, HLA type might also be used to try to identify factors associated with the progression of HIV disease or related conditions. Determining HLA type is also necessary to be able to perform certain research studies.
- Tonsillar biopsy: Examination of tonsil tissue may provide information on the effects of IL-2 on the immune system and the expression of HIV. Patients in the randomized IL-2 study (93-CC-0113) may have tonsillar biopsies done up to three times-soon after enrollment, after month 4, and after month 12. Patients in the open IL-2 study (91-CC-0143) would have procedures no more often than every 3 months, with the following exception: patients in either study who are willing to have repeat biopsies performed during IL-2 therapy will have the procedure done up to three times during a round of IL-2: before Il-2 therapy, day 2-3 or IL-2 therapy, and day 4-6 of IL-2 therapy, if the sequential biopsies can be safely performed. The area to be biopsied will be numbed with a local anesthetic and 1 to 2 small pieces of tissue will be biopsied.
- Skin biopsy: Examination of skin tissue may help to explain how IL-2 causes changes in the skin. Biopsies will be obtained from areas of the skin that have been affected by IL-2 as well as from normal, unaffected areas for comparison. Patients with Kaposi sarcoma will also have biopsies of normal skin to allow comparison with IL-2-induced changes in the Kaposi sarcoma lesions. The areas to be biopsied will be numbed with local anesthetic and a 2-mm (1/10th-inch) piece of skin will be biopsied from each site.
