Trial Outcomes & Findings for Pemetrexed and Carboplatin in Treating Patients With Recurrent Ovarian, Primary Peritoneal, or Fallopian Tube Cancer (NCT NCT01001910)

NCT ID: NCT01001910

Last Updated: 2024-02-28

Results Overview

The primary endpoint is overall response rate defined by proportion of patients achieving complete response, partial response based on RECIST V1.1 or Rustin's criteria as appropriate. Based on RECIST V1.1 for targeting lesions from CT scan: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions; Progressive Disease (PD): At least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study; Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD; Overall response CR + PR. Based on Rustin's criteria, a response to ca125 has occurred if there is at least a 50% reduction in ca125 level from a pretreatment sample. The response must be confirmed and maintained for at least 28 days.

Participant Flow

The sample size calculation was based on the primary endpoint of ORR. According to the Simon 2 stage design, the maximum trial size was set at 46 evaluable patients and stopping rules were based on the error probability limits of α=0.05 and β=0.1. If \< 8 responses were observed among the initial 22 patients, the study would be terminated.

SECONDARY outcome

Timeframe: 4.5 years

Population: The patients that received pemetrexed disodium with carboplatin treatment were evaluated for an grade, grade 3, and grade 4 toxicities for adverse event confirmations.

Secondary outcome included detailed measurement of adverse events from treatment assessed according to National Cancer Institute (NCI) Common Toxicity Criteria (CTC) version 3.0.

Adverse events were graded on a scale of 1 to 4, for unfavorable medical occurrences in a participant whether or not considered related to the participant's participation in the research. The types of toxicities evaluated consisted of "hematologic" versus "non-hematologic." Treatment related deaths were recorded separately from all-cause mortality cases. Frequency of adverse events are calculated based on the total number of events divided by the total number of chemotherapy cycles given.
