About

The purpose of this study is to find out how effective 177Lu -J591 is in the treatment of patients with metastatic, androgen-independent prostate cancer.

Full description

To determine the clinical activity of 177Lu -J591 for the treatment of patients with metastatic, androgen-independent prostate cancer.

Patients will receive a single dose of J591 (total antibody of 20 mg) consisting of antibody chelated with 177Lu at a dose of 65 or 70 mCi/m2 with a specific activity of 12-15 mCi/mg plus non-radiolabeled antibody.

Enrollment: 47 patients

Sex: Male

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Description:

Eligible patients will receive a single dose of 177Lu-J591 (65 or 70 mCi/m2) consisting of J591 chelated at a specific activity of 12-15 mCi of 177Lu per mg of antibody plus sufficient non-radiolabeled, non-DOTA-conjugated ("naked") J591 to achieve a total antibody dose of 20 mg. Each dose will be administered by an IV infusion at a rate not to exceed 5 mg/min.
