| Purpose: |
|
To conduct a randomized dose-ranging study to evaluate the safety and activity of orally
administered low dose interferon alfa-n3 as an immunomodulator in subjects with asymptomatic
HIV-1 infection. The primary endpoints of the study will include an increase or
upregulation in genes known to be mediators of interferon response. Secondary endpoints
will include the absolute CD4 count and plasma HIV RNA levels.

| Study summary: |
|
This study will be an open-label, randomized outpatient study in HIV infected subjects using
a range of doses of Alferon LDO. The first nine (9) patients enrolled will not be
randomized. Instead, the first three (3) patients will receive 500 IU, the second three (3)
patients will receive 1000 IU, and the final three (3) patients will receive 2000 IU. Once
three (3) patients at a given dose level have received at least 8 doses without grade 3
toxicity, patients may be enrolled at the next higher dose level. Following enrollment of
the first nine (9) patients, additional patients will be randomized to receive one of the
three (3) dose levels of Alferon® LDO. The Alferon LDO (natural interferon alfa-n3) will be
in a buffer solution and taken orally once each day for 10 consecutive days at doses equal
to 500 IU, 1000 IU, or 2000 IU.
Pretherapy baseline evaluations will be performed within the three (3) week period prior to
randomization.
Drug will be dispensed for a ten day treatment period, during which time any clinical
symptoms and adverse events will be evaluated. Laboratory samples (2.5 ml blood) for
microarray analysis evaluations will be made twice during baseline and 12-14 hours following
doses 1, 4, and 10 on study days 2, 5, and 11, respectively. |

Inclusion Criteria:
1. 18 years of age or older.
2. HIV-1 plasma RNA > 500 copies/ml (Roche Amplicor assay) or similar assay within 45
days of starting oral dosing.
3. Karnofsky performance status of 100
4. Subjects must be asymptomatic with regard to HIV related clinical symptoms including
the following opportunistic infections: Oral candidiasis (thrush), cutaneous herpes
simplex, fever, diarrhea, weight loss ≥ 10% of body weight, seborrheic dermatitis,
chronic mucocutaneous fungal infections or Kaposi’s sarcoma. Subjects with a history
of AIDS are not eligible.
5. Serum creatinine ≤ 1.5 ULN; serum bilirubin ≤ 2.0 ULN.
6. Total WBC ≥ 3000/mm3, platelet count ≥ 100,000/mm3 and granulocytes ≥ 1500 mm3.
7. Absolute CD4 cell count greater than 400 (based on the average CD4 count from the two
pretherapy tests).
8. Hemoglobin > 10.0 g/dl.
9. AST < 4 times upper normal limit.
10. ALT < 4 times upper normal limit.
11. Serum Albumin > 2.0 g/dl.
12. Written informed consent.
13. Females must either be of non-child bearing potential, or utilize an effective form
of contraception and have a negative pregnancy test within 14 days of entry.
14. For those subjects who are on antiretroviral therapy, they must have been on a stable
dose schedule for at least 90 days prior to study entry and must continue on the same
schedule during the treatment phase of this study.
Exclusion Criteria:
1. Pregnant or nursing women, or women not using an effective form of contraception.
2. Less than 18 years of age.
3. Active IV drug users.
4. Absolute CD4 ≤ 400 mm3 (based on the average CD4 counts from the two pretherapy
tests).
5. Receipt of any immunosuppressive agent, chemotherapy, or systemic steroids within 45
days of study entry.
6. Receipt of any immunomodulator such as BCG vaccine, isoprinosine, or similar
experimental agents within 45 days of study entry.
7. Evidence of chronic hepatitis, or other active gastrointestinal, renal, respiratory,
endocrine, hematologic, cardiovascular, neurological, or psychiatric disorder that
would limit the subject’s ability to complete the study period.
8. Unlikely or unable to comply with the requirements of the protocol.
9. Patients unwilling or unable to give informed consent.
10. Patients on any other concurrent experimental medication.
11. Concurrent, chronic prophylactic use of any systemic antifungal medication (e.g.
ketoconazole, fluconazole, clotrimazole) or of any systemic anti-viral (e.g.
acyclovir or ganciclovir) except for antiretroviral therapy.
12. Patients using any form of interferon therapy during the 6 weeks prior to study
entry. If prior interferon therapy has been received, the subject must not have known
development of antibodies to interferon.
13. Hospitalized subjects, or those with an active viral infection other than HIV, within
2 weeks of study entry.
14. Transfusion dependent subjects (subjects requiring > 1 unit of packed RBC per month
within the 3 months prior to study entry).
15. Subjects who are symptomatic of their HIV infection at study entry. |
