Trial Information

A Phase I/II Trial of SGN-00101 in the Treatment of High-Grade Anal Intraepithelial Neoplasia (AIN) in HIV-Positive Individuals


OBJECTIVES:

I. Determine the safety and maximum tolerated dose of SGN-00101 in HIV-positive patients
with high-grade anal squamous intraepithelial lesions.

II. Determine clinical response and histologic/cytologic regression in patients treated with
this drug.

III. Determine immune response in patients treated with this drug. IV. Determine the effect
of this drug on HIV viral load and CD4 level in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive SGN-00101 subcutaneously once on weeks 0, 4, and 8. Treatment continues in
the absence of disease progression or unacceptable toxicity.

Cohorts of 5-6 patients receive escalating doses of SGN-00101 until the maximum tolerated
dose (MTD) is determined. The MTD is defined as the dose at which no more than 1 of 6
patients experience dose-limiting toxicity.

Patients are followed at 1, 4, and 10 months.

Inclusion Criteria


DISEASE CHARACTERISTICS:

- Histologically confirmed high-grade anal squamous intraepithelial lesions (HSIL) with
residual HSIL of the anal canal or margin by high-resolution anoscopy

- Declined routine surgery or not a candidate for surgical excision of HSIL

- Must have received stable highly active antiviral therapy (HAART) for at least 4
weeks before study

- HAART defined as 3 or more agents, including a protease inhibitor or
nonnucleoside reverse transcriptase inhibitor that is approved or available
through expanded access combination antiviral therapy
