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

  • Metastatic prostate cancer (positive bone scan or measurable disease)
  • Total testosterone of less than 50 ng/dL, except for patients with prior orchiectomy, where testosterone does not need to be measured.
  • Patients who are receiving an antiandrogen as part of primary androgen ablation must demonstrate disease progression following discontinuation of antiandrogen and completion of a washout period and then observe disease progression.
  • Patients must stop using any herbal product known to decrease PSA levels (eg., saw palmetto and PC-SPES) or any systemic or topical corticosteroid at least 4 weeks prior to screening. Progressive disease must be documented after discontinuation of these products.

  • Prior radiation therapy completed at least 4 weeks prior to enrollment. No prior radiopharmaceuticals (strontium, samarium) within 8 weeks prior to enrollment.

Exclusion Criteria:

  • Bone pain due to metastatic bone disease severe enough to require routine narcotic analgesic use.
  • History of severe hypersensitivity reactions to drugs formulated with polysorbate 80.
  • Patients with active autoimmune disease or a history of autoimmune disease that required systemic steroids or immunosuppressive medications, except for patients with vitiligo.
  • Prior therapy with any anti-cytotoxic T-lymphocyte antigen 4 (anti-CTLA-4) antibody.
