Brief summary

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.

Detailed 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.

Interventions

DRUG177Lu Radiolabeled Monoclonal Antibody HuJ591 (177Lu -J591)

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.

Define the Measurable Disease Response Rate.Disease will be assessed at baseline and day 85.Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression). Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study

Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression). Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study
