Trial Information

A Phase I Trial of Recombinant Vaccinia Virus That Expresses DF3/MUC1 in Patients With Metastatic Adnocarcinoma of the Breast

OBJECTIVES: I. Determine the toxicity associated with repeated vaccination with recombinant
vaccinia DF3/MUC1 vaccine (rV-DF3/MUC1) in patients with metastatic breast cancer. II.
Determine the maximum tolerated dose of rV-DF3/MUC1, based on cellular and humoral immunity,
in these patients. III. Determine whether vaccination with rV-DF3/MUC1 is associated with
antitumor activity in these patients.

OUTLINE: This is an open label, dose escalation study. Patients receive recombinant vaccinia
DF3/MUC1 vaccine (rV-DF3/MUC1) intradermally. Treatment repeats every month for 3 courses in
the absence of disease progression or unacceptable toxicity. Cohorts of at least 6 patients
receive escalating doses of rV-DF3/MUC1 until the maximum tolerated dose (MTD) or the
highest dose level to be tested is reached. The MTD is defined as the dose preceding that at
which 2 of 6 patients experience dose limiting toxicity. Patients are followed monthly for 6

PROJECTED ACCRUAL: A total of 16-28 patients will be accrued for this study within 1-2
