Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

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.

Intervention code [1] 322136 0
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.

Outcomes
Primary outcome [1] 329476 0
To characterize the tumor uptake of 68Ga-NTA-14 as compared to
68Ga-PSMA I&T in participants with mCRPC using SUVmax, SUVmean and
total tumor volume by PET/CT quantitation.
Timepoint [1] 329476 0
3 hours post-imaging
Primary outcome [2] 329719 0
To characterize the uptake and wash out of 68Ga-NTA-14 as
compared to 68Ga-PSMA I&T in normal organs (eg salivary glands, kidneys, duodenum)
Timepoint [2] 329719 0
3 hours post-imaging
Secondary outcome [1] 402749 0
To evaluate the safety of 68Ga-NTA-14 by incidence of adverse events
Timepoint [1] 402749 0
Due to intravenous infusion, local site irritation, bleeding or infection could be experienced. Radiation exposure is minimum for patients.
adverse effects to be assessed 4 hours post-imaging clinically as per patient reported on study data collection forms.
Secondary outcome [2] 403584 0
To evaluate the dosimetry of 68Ga-NTA-14
Timepoint [2] 403584 0
3 hours post-imaging from study records as per standard SOP guidelines.

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.
