Trial Outcomes & Findings for 68Ga-PSMA-R2 in Patients With Biochemical Relapse (BR) and Metastatic Prostate Cancer (mPCa) (NCT NCT03490032)

NCT ID: NCT03490032

Last Updated: 2020-11-17

Results Overview

Treatment-emergent adverse events (TEAEs) were collected from first dosing (single administration, Day 1) up to last follow-up visit or until the event has resolved to baseline grade or better or the event was assessed stable by the investigator or the patient was lost to follow-up or withdrew consent. The distribution of adverse events was done via the analysis of frequencies for treatment emergent Adverse Event (TEAEs), Serious Adverse Event (TESAEs) and Deaths due to AEs, through the monitoring of relevant clinical and laboratory safety parameters. Only descriptive analysis performed.

SECONDARY outcome

Timeframe: 68Ga-PSMA-R2 PET imaging acquired at Day 1 (20-30 min post-injection, 1 hour, 2 hours and 3-4 hours post-injection)

Population: Full Analysis Set (FAS). Only participants with a value at each post-injection timepoints were included in the analysis.

PET/CT scans were performed at approximately 20 to 30 min and at 1, 2, 3 to 4 hours postinjection. Time activity curves (TACs) for various organs (Brain, Heart Wall, Kidney, Lacrimal Gland, Liver, Lungs, Salivary Gland, Spleen and Thyroid) were produced as decay-corrected tissue of injected activity (mSv/MBq) per organ. Only descriptive analysis performed.

Population: Full Analysis Set (FAS)

Targeting properties of 68Ga-PSMA-R2 were evaluated by semi-quantitatively assessing radiotracer uptake at lesion level, identified via PET/CT imaging (4 scans). The lesion Tumor to Background Ratio (TBR) was defined as SUVmax(lesion) / SUVmean(gluteal or thigh) was calculated and reported by lesion location with summary statistics at all imaging time points.

Timeframe: 68Ga-PSMA-R2 PET imaging acquired at Day 1 (1 hour, 2 hours post-injection)

Population: Full Analysis Set (FAS)

The subject-level positive percent agreement, negative percent agreement, and overall percent agreement was calculated based on the number of subjects with at least 1 positive lesion detected by conventional scan or at least 1 positive lesion detected by PET scan. These percent agreements were calculated as follows: * Positive percent agreement: a/(a+c) × 100 * Negative percent agreement: d/(b+d) × 100 * Overall percent agreement: (a+d)/(a+b+c+d) × 100 Where: * a = number of subjects with at least 1 positive lesion detected by conventional scan and at least 1 positive lesion detected by PET scan * b = number of subjects with at least 1 positive lesion detected by PET scan that was not correlated with conventional scan * c = number of subjects with at least 1 positive lesion detected by conventional scan that was not correlated with PET scan * d = number of subjects with no lesions detected by conventional scan or PET scan.
