About this study

Official title: 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.

    AEs graded using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0. AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Grade (Gr) 1=Mild, Gr 2=Moderate, Gr 3=Severe, Gr 4= Potentially Life-threatening or disabling, Gr 5=Death. Related=relationship to study drug reported as certain, probable, possible, or missing. Immune-related AE (irAE) was defined as a clinically significant AE of any organ that is associated with drug exposure, of unknown etiology, and is consistent with an immune-mediated mechanism. Day 1=first day of study treatment.

    Measured: Day 1 to last day of study treatment (+70 days) up to 2 years

  2. Number of Participants With Best PSA Response at Day 85 by Category - PSA Evaluable Participants

  2. Number of Participants With Best Overall Tumor Response by Category - Tumor Evaluable Participants

    For those with measurable disease, tumor response based upon tumor lesions (per investigator) using Response Evaluation Criteria in Solid Tumors (RECIST). Best Overall=Participants with a best tumor response of CR or PR at anytime during the study. CR=Disappearance of all target lesions; PR=At least a 30% decrease in the sum of the longest diameter (LD) of target lesions taking as reference, baseline sum LD. For a status of CR or PR, changes in tumor measurements were confirmed by repeat studies no less than 4 weeks after the criteria for response were first met; Unconfirmed=not confirmed by repeat measurements; SD=Neither sufficient decrease to qualify for PR nor sufficient increase to qualify for progressive disease (PD), taking as reference the smallest sum LD since the treatment started; PD=At least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.

    Measured: Day 1 to last day of study treatment (+70 days) up to 2 years

  3. Time to PSA Response at Day 85 in Participants With Complete Response (CR) or Confirmed Partial Response (PR) at Day 85

    Time to PSA response was measured in months. Time to PSA response was analyzed in those participants with CR or PR at Day 85. CR=PSA concentration < 2 ng/mL, confirmed at least 4 weeks after 1st value; PR=PSA concentration ≤ 50% of PSA reference, confirmed at least 4 weeks after 1st value.

    Measured: Day 1 to Day 85

  4. Overall Tumor Response Rate in 10 mg/kg Ipilimumab Monotherapy and Ipilimumab/XRT Combination Therapy

    Tumor response rate was defined as the number of participants with a best response of partial or complete response divided by the total number of tumor evaluable participants. Overall Tumor Response was defined as participants with a tumor response of CR or PR at anytime during the study. CR=Disappearance of all target lesions; PR=At least a 30% decrease in the sum of the longest diameter (LD) of target lesions taking as reference, baseline sum LD. For a status of CR or PR, changes in tumor measurements were confirmed by repeat studies no less than 4 weeks after the criteria for response were first met

  5. PSA Response Rate at Day 85 and Overall PSA Response Rate in 10 mg/kg Monotherapy and Combination Therapy

    PSA response rate was defined as the number of participants with a PSA response (PR or CR) divided by the total number of PSA evaluable participants. PSA response at Day 85, as reported by the investigator, was defined as a PSA concentration < 50% of the PSA reference value occurring on or before Day 85 and this response was confirmed at least 4 weeks after the first determination. The PSA reference value was the PSA concentration measured immediately prior to treatment. Overall Response is < 50% of the PSA reference value occurring anytime after treatment was initiated and this response was confirmed at least 4 weeks after the first determination. Complete response=PSA concentration < 2 ng/mL, confirmed at least 4 weeks after first value; Partial response=PSA concentration ≤ 50% of PSA reference value, confirmed at least 4 weeks after first determination.

Primary causes of deaths are listed under each timepoint.

    Measured: Day 1 to 5 years post treatment

  7. Overall Survival at Completion of Follow Up Period - Treated Participants

    Overall Survival (OS) was defined as the time from the first date of study treatment until the date of death and was measured in months. For those participants who have not died, OS was censored at the last date the participant was known to be alive. Completion of follow-up for OS was a minimum time of eligibility 54 months to a maximum of 85 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing MDX-010 in people with Prostate Cancer and Neoplasm Metastasis, run by Bristol-Myers Squibb at 14 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 28 Aug 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Serious AEs (SAEs), Adverse Events (AEs) Leading to Discontinuation, and Immune-related AEs - Treated Participants (time frame: Day 1 to last day of study treatment (+70 days) up to 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00323882, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Aug 2014; AzTrials last refreshed its copy on 7 Nov 2026.
