Trial Outcomes & Findings for Multi-Tracer Positron Emission Tomography in Patients With Solid Tumors (NCT NCT01243333)

NCT ID: NCT01243333

Last Updated: 2024-04-17

Results Overview

The patients underwent baseline and repeat PET/CT imaging (after one to two cycles of treatment) with \[F-18\]fluorodeoxyglucose (FDG) and \[F-18\]fluorothymidine (FLT). The percent change in the SUVmax for FDG was calculated and used to determine the response. Partial response (PR) was defined as 35% or greater reduction in SUVmax, Progressive Disease (PD) was defined as 35% or greater increase in SUVmax, and Stable Disease (SD) was defined as all other changes in SUVmax.

PRIMARY outcome

Timeframe: 1-2 cycles of treatment - approximately one month

The patients underwent baseline and repeat PET/CT imaging (after one to two cycles of treatment) with \[F-18\]fluorodeoxyglucose (FDG) and \[F-18\]fluorothymidine (FLT). The percent change in the SUVmax for FDG was calculated and used to determine the response. Partial response (PR) was defined as 35% or greater reduction in SUVmax, Progressive Disease (PD) was defined as 35% or greater increase in SUVmax, and Stable Disease (SD) was defined as all other changes in SUVmax.

The patients underwent baseline and repeat PET/CT imaging (after one to two cycles of treatment) with \[F-18\]fluorodeoxyglucose (FDG) and \[F-18\]fluorothymidine (FLT). The percent change in the SUVmax for FLT was calculated and used to determine the response. Partial response (PR) was defined as 35% or greater reduction in SUVmax, Progressive Disease (PD) was defined as 35% or greater increase in SUVmax, and Stable Disease (SD) was defined as all other changes in SUVmax.

PRIMARY outcome

Timeframe: 1-2 cycles of treatment - approximately one month

The patients underwent baseline and repeat PET/CT imaging (after one to two cycles of treatment) with \[F-18\]fluorodeoxyglucose (FDG) and \[F-18\]fluorothymidine (FLT). Percent change in lesion measurements according to standard response criteria for the patient's tumor type were obtained. For brain tumors, Response Assessment in Neuro-Oncology (RANO) criteria were used. Partial Response (PR) was defined as 50% or greater reduction in lesion measurements, Progressive Disease (PD) was 25% or greater increase in measurements, and Stable Disease (SD) was neither PD or PR. Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria were used for solid tumors, with PR defined as 30% or greater reduction in measurements, PD was 20% or greater increase in measurements, and SD was all other changes.
