Trial Outcomes & Findings for FDG-PET in Advanced Melanoma (NCT NCT02236546)

NCT ID: NCT02236546

Last Updated: 2017-04-13

Results Overview

The primary imaging metric is percent change in average FDG standardized uptake value (SUV) among the same target lesions between baseline and images acquired after completion of cycle 1. The relationship between tumor SUV change and size change will be assessed using standard linear regression.

Participant milestones

Participant milestones
Measure
FDG-PET/CT
Patients undergo \[18F\]fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) up to 2 weeks prior to first dose of therapy, after completion of the first treatment course (day 21), and after completion of the fourth treatment course (day 84). Molecular assays on biopsied tissue obtained from a subset of patients will also undergo molecular assays, the results from which will be correlated with FDG-PET/CT data. \[18F\]fluorodeoxyglucose: FDG is administered intravenously approximately 60 minutes prior to the start of PET image acquisition. Molecular assays on biopsied tissue: Correlative studies positron emission tomography: Undergo FDG-PET/CT computed tomography: CT that is part of FDG-PET/CT is a low-milliampere, low-resolution scan that is used for anatomic localization and attenuation correction for PET images.

PRIMARY outcome

Timeframe: Baseline to the completion of 6 courses of treatment

Population: Due to loss of funding data were not collected

The primary imaging metric is percent change in average FDG standardized uptake value (SUV) among the same target lesions between baseline and images acquired after completion of cycle 1. The relationship between tumor SUV change and size change will be assessed using standard linear regression.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Day 84

Population: Due to loss of funding data were not collected

The ability of the percent change in average standardized FDG uptake to predict OR will be assessed using the proportional odds model.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Time from first treatment until objective tumor progression or death for any reason, assessed up to 7 years

Population: Due to loss of funding data were not collected

Cox (proportional hazards) regression will be used to assess the association between the percent change in average standardized FDG uptake and PFS.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Baseline to day 21

Population: Due to loss of funding data were not collected

The association between the changes in tumor FDG accumulation with a panel of immunohistochemical biomarkers will be assessed with the Spearman correlation statistic. 95% confidence intervals will be calculated for each variable. Paired changes in biomarker expression between biopsied (i.e., baseline) and biopsy samples will be compared using the nonparametric Wilcoxon signed rank test. Change in binary expression will be compared using McNemar's test. The Wilcoxon rank sum test (or Kruskal Wallis test for more than 2 groups) will be used to compare continuous and ordinal variables.
