Oxaliplatin and Pemetrexed Disodium in Treating Patients With Refractory Hormone-Resistant Prostate Cancer

February 5, 2014 updated by: University of Southern California

A Phase II Trial of Oxaliplatin and Pemetrexed in Hormone Refractory Prostate Cancer

This phase II trial studies how well giving oxaliplatin and pemetrexed disodium together works in treating patients with refractory hormone-resistant prostate cancer. Drugs used in chemotherapy, such as oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Pemetrexed disodium may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving oxaliplatin together with pemetrexed disodium may kill more tumor cells.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

PRIMARY OBJECTIVES: I. To determine the response rate by Response Evaluation Criteria In Solid Tumors (RECIST) criteria, prostate-specific antigen (PSA) response by the PSA Working Group criteria, and overall clinical benefit defined by summation of RECIST complete responses (CR) plus RECIST partial responses (PR) plus PSA PRs. SECONDARY OBJECTIVES: I. To determine time to progression in patients with hormone-refractory prostate cancer (HRPC) receiving oxaliplatin and pemetrexed. II. To describe the safety profile of this treatment. III. Pain response will be evaluated in an exploratory manner. IV. Undertake a pilot analysis of excision repair cross-complementing 1 (ERCC1) expression levels and polymorphisms, looking at their ability to predict response to platinum therapy. OUTLINE: Patients receive oxaliplatin intravenously (IV) over 2 hours and pemetrexed disodium IV on day 1. Courses repeat every 21 days for up to 1 year in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 6 months.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Best Overall Response
Time Frame: RECIST evaluation: Baseline, after every 2 courses, and then every 6 months after off-study, up to 1 year. PSA evaluation: baseline, day 1 of each course, final evaluation, and then every 6 months after off-study, up to 1 year
For patients with measurable disease, the RECIST 1.0 criteria was used to determine response. Complete Response = disappearance of all target lesions, Partial Response = greater or equal to 30% decrease in sum of longest diameter or target lesions, Stable Disease = <30% decrease or <20% increase, Progressive Disease = greater or equal to 20% increase in longest diameter of target lesions. For patients who do not have measurable disease by RECIST, the response was based on PSA response defined by Prostate Cancer Working Group criteria (1999) as 50% reduction in PSA confirmed on a second measurement at least 4 weeks later.
RECIST evaluation: Baseline, after every 2 courses, and then every 6 months after off-study, up to 1 year. PSA evaluation: baseline, day 1 of each course, final evaluation, and then every 6 months after off-study, up to 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Time to Disease Progression and Overall Survival
Time Frame: Baseline, after every 2 courses, and then every 6 months after off-study (RECIST) until progression; or baseline, day 1 of each course, at the final evaluation, and then every 6 months after off-study (PSA) until progression
Progression-free survival was defined as the time from the first infusion of study treatment to the date of radiographic disease progression according to RECIST 1.0, or until two consecutive PSA rises occurred with an absolute increase of 5 ng/mL and a 50% relative increase over baseline. For patients without documented disease progression, the date of death or last follow-up without disease progression was used.
Baseline, after every 2 courses, and then every 6 months after off-study (RECIST) until progression; or baseline, day 1 of each course, at the final evaluation, and then every 6 months after off-study (PSA) until progression
Number of Participants With Serious Adverse Events (SAEs)
Time Frame: Baseline, days 1 and 7 of each course, and at last evaluation, up to 1 year
Safety evaluation according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 3.0.
Baseline, days 1 and 7 of each course, and at last evaluation, up to 1 year
