Trial Information

Phase II Trial of Atragen and Interferon Alfa-2b in Patients With Advanced Renal Cell Carcinoma


- Determine the response in patients with metastatic renal cell carcinoma treated with
tretinoin liposome and interferon alfa-2b.

- Determine the toxicity of this regimen in these patients.

- Study retinoic acid receptor expression on tissue obtained from selected patients who
have tumor biopsies.

OUTLINE: This is a dose-escalation study of tretinoin liposome with concurrent individual
dose escalation of interferon alfa-2b. (Phase I closed to accrual as of 9/24/03.)

Patients receive tretinoin liposome IV over 30 minutes once weekly and interferon alfa-2b
subcutaneously on five consecutive days (M-F) for 8 weeks. Courses repeat every 8 weeks in
the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of tretinoin liposome until the maximum
tolerated dose (MTD) has been determined. The MTD is defined as the dose preceding that at
which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is
determined additional patients are accrued and treated at that dose. (Phase I closed to
accrual as of 9/24/03.)

During the first 3 weeks of the study, patients receive interferon alfa-2b at weekly dose
escalations. After week 3, patients continue at the highest acceptable dose level of
interferon alfa-2b for the remainder of the study. (Phase I closed to accrual as of

Patients are followed at 30 days after the last treatment.

PROJECTED ACCRUAL: A total of 3-18 patients will be accrued into the phase I portion of this
study (Phase I closed to accrual as of 9/24/03). A total of 14-25 patients will be accrued
into the phase II portion of this study.
