Descrizione dettagliata
OUTLINE:
Patients receive [18F]FTT intravenously (IV) and 60, 90, or 150 minutes later undergo PET/CT within 30 days prior to day 1 cycle 1 of GCD and 12 weeks after starting GCD in the absence of unacceptable toxicity. Patients also undergo CT and/or magnetic resonance imaging (MRI) throughout the study.
After completion of study intervention, patients are followed up at week 24 and then up to 6 months after completing GCD treatment.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Relationship between standardized uptake value maximum (SUVmax) and overall response rate
Lasso di tempo: At baseline and 24 weeks after starting gemcitabine, cisplatin, and durvalumab (GCD)
|
Baseline SUVmax will be extracted from a region of interest (ROI) placed on the tumor lesion of interest using a 40% threshold.
Will assess overall response rate at 24 ± 2 weeks after starting GCD by using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.
Response will be analyzed as a binary outcome.
Differences in baseline SUVmax between responders and non-responders will be evaluated using the Wilcoxon rank-sum test.
Logistic regression models will be used to estimate the direction and magnitude of association, with response as the dependent variable and SUVmax as the predictor.
Odds ratios and 95% confidence intervals will be reported.
Analysis will focus on estimation of effect sizes and the direction and magnitude of associations of the primary endpoints, overall response rate and SUVmax of the most avid lesion, rather than formal hypothesis testing alone.
Boxplots will be used to visualize the distribution of SUVmax by responders group.

Misure di risultato secondarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Relationship between standardized uptake value mean (SUVmean) and overall response rate
Lasso di tempo: At baseline and 24 weeks after starting GCD
|
Will measure baseline SUVmean from an ROI placed on the tumor lesion of interest using a 40% threshold.
Treatment response will be defined by RECIST 1.1 criteria at 24 ± 2 weeks following GCD treatment.
Association between baseline SUVmean and treatment response will be evaluated using Wilcoxon rank-sum test.
Logistic regression will be used to quantify the magnitude and direction of association between baseline SUVmean and response.
Results will be summarized using odds ratios with 95% confidence intervals, and boxplot to illustrate the distribution of baseline SUVmean between responders and non-responders.

Change in SUVmax and response
Lasso di tempo: Baseline to 12 weeks after starting GCD
|
Will calculate the change of SUVmax from baseline to 12 ± 2 weeks after starting GCD.
Due to the limited sample size, will use the nonparametric method Wilcoxon Rank Sum test to evaluate the difference in change between responders and non-responders.
Effect sizes will be summarized using the median difference (Hodges-Lehmann estimator) in change between groups with 95% confidence intervals.
