Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
NTA-14 is a peptidomimetic that binds to prostate-specific membrane antigen (PSMA), which is a transmembrane protein expressed at low levels in normal prostate tissue and in other organs and tissues, but its expression is markedly increased on prostate cancer cells.
This is a single arm prospective trial that will evaluate the ability of a novel imaging agent (68Ga-NTA-14) to detect metastatic castration resistant prostate cancer (mCRPC). Participants will undergo PET/CT imaging with 68Ga-NTA-14.
Participants will receive a single administration of 68Ga-NTA-14 via intravenous infusion by a radiation nurse/specialist prior to PET/CT imaging on Day 1. PET/CT scans will be performed at 1 hour and 3 hours after administration of each imaging agent. 68Ga-NTA-14 will be injected at a dose of 200 MBq.

Diagnosis / Prognosis
Comparator / control treatment
This study utilizes the PSMA binding small molecule PSMA I&T which has an identical PSMA binding moiety as PSMA-617 and a well characterized biodistribution profile. 68Ga-PSMAI&T is a small molecule that also binds PSMA and for which the normal tissue and tumor binding have been well described.
After 68Ga-NTA-14 scans conducted at day 1, patient is required to come back between Day 3-8, a single administration of 68Ga-PSMA I&T will be administered via intravenous infusion by a radiation nurse/specialist prior to PET imaging. PET/CT scan will be performed one time 1 hour post administration of the agent.
68Ga-PSMA I&T will be injected at a dose of 200 MBq.

Statistical methods / analysis
No prospective statistical analyses are proposed.
This is an exploratory study which will initially assess 68Ga-NTA-14 uptake in tumor and normal tissues, with the goal of determining if additional clinical development of NTA-14 is warranted. Retrospective statistical analyses of uptake with 68Ga-NTA-14, or a comparison of uptake between 68Ga-NTA-14 and 68Ga-PSMA I&T, may be performed if the dataset is large enough to support a meaningful evaluation.

Summary
Brief summary
This is a single arm prospective trial that will evaluate the ability of a novel imaging agent (68Ga-NTA-14) to detect metastatic castration resistant prostate cancer cells within the prostate and other tissues.

Who is it for?
You may be eligible for this study if you are a male aged 18 years or older and you have been diagnosed with prostate cancer that is metastatic and castration resistant (has not responded to surgical removal).

Study details
Participants who choose to enrol in this study will receive a single administration of 68Ga-NTA-14 (into a vein) 1 hour prior to Positron Emission Tomography (PET)/Computed Tomography (CT) imaging on Day 1. Between Day 3-8, a single administration of 68Ga-PSMA I&T will be administered (into a vein) 1 hour prior to PET imaging. PET/CT scans will be performed at 1 hour and 3 hours after administration of NTA-14 imaging agent and 1 hour after 68Ga-PSMA imaging agent. Participants will undergo safety monitoring which will include assessment of any side effects at 4 hours after administration of 68Ga-NTA-14.

Participation will require up to 8 days including screening (Day -30 to 0), imaging with 68Ga-NTA-14 (Day 1), and imaging with 68Ga-PSMA I&T (Day 3-8).
Participants will be followed up 1 hr post 68Ga-NTA-14 administration for evaluation of side effects.

It is hoped this research will demonstrate that 68Ga-NTA-14 can be administered to patients without serious side effects, and that the images produced by this agent will be similar to or of better able to detect metastatic castration resistant prostate cancer cells compared to 68Ga-PSMA I&T images.
