Brief summary

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.

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.

PSA evaluation: baseline, day 1 of each course, final evaluation, and then every 6 months after off-study, up to 1 yearFor 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.

Outcome results

Primary

Best Overall Response

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.

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

Population: All participants who received at least 1 cycle of treatment were included.

Time to Disease Progression and Overall Survival

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.
