Study of MDX-010 in Patients With Metastatic Hormone-Refractory Prostate Cancer

August 14, 2014 updated by: Bristol-Myers Squibb

A Phase I/II, Open-label, Dose-escalation Study of MDX-010 Administered Every 3 Weeks for 4 Doses in Patients With Metastatic Hormone-Refractory Prostate Cancer

Multicenter study in which patients with metastatic hormone refractory prostate cancer (HRPC), who have not had previous chemotherapy or immunotherapy treatments, received MDX-010 every 3 weeks for 4 doses (12 weeks total duration of induction). MDX-010 was administered at escalating dosage levels of 3, 5, and 10 mg/kg/dose infusions. At least 6 patients were to be enrolled in each dosage level. Patients who tolerated and responded to treatment or who had stable disease for 3 months or longer and who subsequently progressed during the follow up phase of the study had the option to receive additional treatment with MDX-010, up to 4 cycles. Patients were followed in the study for response up to 2 years and were followed for survival status for up to 5 years after enrollment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:
