Brief Summary

The intent of this study is to evaluate actionable outputs from TRAQinform Theranostics in a prospective, multi-center, non-interventional clinical study. The primary objective is to investigate intent-to-change treatment decisions after the addition of TRAQinform Theranostics. The exploratory objective is to investigate if treatment efficacy and treatment-related toxicity could be detected by TRAQinform Theranostics following PSMA PET/CT at week 12.

Detailed Description

To fully understand the clinical impact of TRAQinform Theranostics on a clinical workflow, this prospective, multi-center, non-interventional clinical study will evaluate actionable outputs from TRAQinform Theranostics, a software only medical device that identifies, quantifies, tracks, and compares lesions between different imaging modalities and multiple imaging timepoints. The primary objective of this clinical study is to investigate intent-to-change treatment decisions after the addition of TRAQinform Theranostics.

The exploratory objective is to investigate if treatment efficacy and treatment-related toxicity can be detected by TRAQinform Theranostics in week 12 of 177Lu-PSMA (Pluvicto) treatment.

This clinical study will enroll 32 metastatic prostate cancer patients, planned to start treatment with 177Lu-PSMA (Pluvicto). Enrolled subjects will receive a 68Ga-PSMA or 18F-DCFPyL PET/CT and a diagnostic CT at baseline (SOC) and again at week 12 of the 177Lu-PSMA treatment. Week 12 PET/CT is for research purposes only and the 68PSMA or 18F-DCFPyL imaging agent may be considered investigational.

Following each imaging timepoint, scans will be transmitted to AIQ for analysis. At baseline and again at week 12, the investigator team, using the PET/CT and other relevant clinical data, will make a treatment decision without TRAQinform Theranostics and complete a questionnaire .

The TRAQinform Theranostics report will then be sent to the investigator team after the patient's treatment decision is made and the team again, will then provide answers to the questionnaire assessing how TRAQinform Theranostics would have impacted treatment decisions.

To address the status quo bias of each local investigator team, a blinded clinical evaluation of the week 12 questionnaire and any other anonymized clinical data necessary to make a treatment decision (prior taxane treatments, relevant labs, physical examination, treatment toxicities, and recent medical history) will be shared with each site. The investigator teams at each site will independently answer the week 12 questionnaire considering all information but without knowledge of the treatment decision made by the investigator teams at the other site.

It is important to note that the objective of this clinical study is to evaluate only the "intent" to change treatment. The investigator teams agree that patient treatment management decisions will not be affected by the additional information from TRAQinform Theranostics, and no clinical intervention will be implemented.

Primary Outcome Measures

Name	Time	Method
Investigate intent to change treatment decisions after the addition of the TRAQinform Theranostics	12 weeks	Medical teams make a treatment decision using the PSMA PET/CT, diagnostic CT, and other clinical data without the TRAQinform Theranostics analysis report. A treatment decision questionnaire is completed. The medical team is then given the TRAQinform Theranostic report, and the treatment decision questionnaire is completed again.; TRAQinform Theranostic analyzes PSMA PET/CT and CTs. A pdf report allows a medical team to view and interpret the TRAQinform outputs. The report is a theranostic tracer concordance analysis of the PSMA PET/CT and the diagnostic CT for lesions and organs. PSMA PET/CT metrics include SUVmax, SUVmean, Volume and Slice. CT metrics include Volume and Slice. Treatment decisions with/without TRAQinform Theranostics report will be evaluated by calculating the Kappa Index, reported with corresponding 95% confidence interval. Logistic regression analysis will be conducted to correlate decisions with outcomes.

Secondary Outcome Measures

Name	Time	Method
Investigate if treatment efficacy and treatment-related toxicity could be detected by the TRAQinform Theranostics	12 weeks	Clinical reports and patient history information from the PRRT patient dataset will be used to identify patients with PRRT-related toxicities (nephrotoxicity, xerostomia, bone pain flair, thrombocytopenia). Toxicity type, grade, and date of first known presence of toxicity will be captured. In addition to identifying single imaging metrics that may predict toxicity, an updated TRAQinform Profile model will be trained to predict patient toxicity status using baseline only imaging and dosimetry metrics and a combination of baseline, follow-up, and response metrics.
