Pilot Study of p53 Intralesional Gene Therapy With Chemotherapy in Breast Cancer


OBJECTIVES:

I. Determine the effect of adenovirus p53 (Ad-p53) on chemotherapy-induced apoptosis in
lesions in patients with breast cancer.

II. Determine p53 protein expression following intralesional injections of Ad-p53 by
immunohistochemistry and reverse transcriptase polymerase chain reaction in this patient
population.

III. Determine the time course and magnitude of the development of a humoral antibody
response to the adenoviral vector in this patient population.

IV. Determine the ability of transfected p53 to upregulate downstream signals important in
G1 arrest by assaying for WAF1 mRNA and apoptosis in this patient population.

V. Determine the toxicities and side effects of intralesional injections of Ad-p53 given in
combination with standard chemotherapy in patients with cutaneous and subcutaneous
metastatic breast cancer amenable to injections and biopsies.

VI. Determine if there is an increase in apoptosis induced by Ad-53 compared to baseline in
this patient population.

OUTLINE:

Patients undergo biopsy of one of their skin nodules prior to any treatment. Patients
receive the Ad-p53 gene therapy in one nodule and injection of a second nodule with
Dulbecco's phosphate buffered saline. The next day, patients begin chemotherapy, which may
be given weekly and continues every 21-28 days for up to 6 courses. On day 3, patients
return for biopsy of injected nodules. Biopsies are only performed during the first course.
Patients may receive further injections of the Ad-p53 gene with subsequent courses of
chemotherapy, for up to six courses.

Patients are followed monthly for 4 months.
