Home Treatment of HIV-Infected Patients With Interleukin-2 With or Without a Tumor Necrosis Factor Antagonist

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00001475

Brief Summary:

Patients enrolled in NIH protocol 95-I-0133 at the Clinical Center may participate in an extension phase of this study in which the drug prednisone will be eliminated from the treatment regimen. Prednisone is associated with avascular necrosis, a condition that has been found in a number of patients in this study. Also, certain patients in this protocol may receive future interleukin-2 treatment cycles at home. 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.

To be eligible for home administration of IL-2, patients must:

  • Be enrolled in a current NIAID protocol for IL-2 therapy and have received at least 1 year of treatment on the protocol, with at least two well-tolerated outpatient cycles at a stable dose.
  • Have a history of tolerable side effects while receiving IL-2 without frequent medical interventions, intravenous fluid replacement or dose reductions.
  • Not have had any significant clinical or laboratory abnormalities during days 0 to 5 of the last two outpatient cycles.
  • Have a strong relationship with a private physician or health-care provider who has been involved in the patient's care and is willing to help supervise the patient's care during each home IL-2 cycle.
  • Live in a home with easy telephone access and have proved reliable in responding to telephone calls from clinic staff.
  • Give the clinic staff contact information for a close friend or relative who will agree to serve as a caregiver during each home cycle, providing the patient non-medical assistance and checking on his or her condition daily.
  • Have reasonable access to emergency medical services and a nearby medical facility.
  • Have proved reliable and consistent in using sterile technique, reconstituting IL-2 vials and administering subcutaneous IL-2 injections.
  • Be receiving outpatient IL-2 injections cycles at least once every 6 months as part of their normal protocol participation.
  • Have access to a home weight scale and be able to weigh themselves each day for safety monitoring.

Participants will receive IL-2 cycles on the same schedule they followed in their original protocol participation. 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 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 any complications or other problems that develop with therapy.

Condition or disease Intervention/treatment Phase
Acquired Immunodeficiency Syndrome HIV Infection Drug: IL-2 plus Anti-TNF or Thalidomide Phase 2

Detailed Description:

In the initial phase of this study, HIV-infected patients with CD4 counts between 200 and 500 were randomized to receive either IL-2 alone by continuous IV infusion for 5 days every 8 weeks, IL-2 plus anti-TNF antibody, or IL-2 plus thalidomide. The primary endpoints of this study are safety and tolerability of the IL-2/TNF inhibitor combination. Secondary endpoints will include changes in CD4 counts, frequency and severity of IL-2 related side effects, changes in serum TNF levels, and plasma viral load changes. The study period is one year, with an optional extension period to follow. Enrollment was for up to forty-five IL-2-naive patients.

In the amended phase of this study, up to 60 patients with HIV infection and CD4 counts equal to or greater than 350 will be studied to determine the ability of prednisone to ameliorate IL-2 related toxicity. Patients will be randomized to one of four groups: IL-2 alone; IL-2 plus prednisone; prednisone alone; no treatment. All four groups will be treated with a combination regimen of antiretrovirals to include at least one protease inhibitor. IL-2 will be dosed SQ at a starting dosage of 7.5 mlU bid x 5 days every 8 weeks, and prednisone (or placebo) will be dosed at 0.5 mg/kg/day during IL-2 cycles. Primary endpoints are frequency of IL-2 associated fatigue and fever, CD4 count changes, and viral load changes. Secondary endpoints include frequency of other IL-2 side effects, concomitant medication use, steroid associated side effects, cytokine changes during IL-2, and IL-2 total exposure in the IL-2 plus steroid vs. IL-2 plus placebo arms. The study period is one year with an optional extension period to follow.

Current treatment with a stable regimen or licensed anti-retroviral therapy for at least 2 weeks.

Adequate venous access in the upper extremities for repeated blood drawing and intravenous catheter placement.

No prior IL-2 therapy.

No patients exhibiting psychiatric disturbance or illness which in the assessment of the protocol team may affect patient safety or compliance.

No patients with significant cardiac, pulmonary, rheumatologic, thyroid, kidney, gastrointestinal or neurological disease that could either decrease absorption of oral therapy, prove a cardiovascular risk during the fluid shifts and stresses that occur with IL-2 therapy, or that could have an inflammatory/immune etiology and thus might be activated or worsened by IL-2.

No patients with hypertension requiring continuous anti-hypertensive therapy.

No pregnant or lactating patients.

Women of childbearing potential must agree to practice abstinence or use 2 forms of contraception simultaneously beginning 1 month prior to receiving study medication and continuing thereafter until 1 month after the last dose of study medication.

Active participation in protocols 91-CC-0113 or 93-CC-0143.

Negative urine pregnancy test within 2 weeks prior to study entry (for women of childbearing potential).
