Overview

68Ga-AAZTA-093 is a novel radiotracer incorporating a hypoxia sensitive nitroimidazole(NI)-moiety and a PSMA-targeting. In this study, we observed the safety, biodistribution, radiation dosimetry and diagnostic value of 68Ga-AAZTA-NI-093 PET/CT in patients with prostate cancer.

Description

Prostate cancer (PCa) is one of the most common malignancies worldwide in men. Prostate specific membrane antigen (PSMA), as known as folate hydrolase I or glutamate carboxypeptidase II, is overexpressed on the cells of prostatic adenocarcinoma. Various low molecular weight radiopharmaceuticals targeting PSMA such as PSMA-11, PSMA-617 for 68Ga- or 177Lu- labeling have been developed. 68Ga-AAZTA-NI-093 is a novel agent incorporating a hypoxia sensitive nitroimidazole(NI)-moiety and a PSMA-targeting. This pilot study was prospectively designed to evaluate the safety, biodistribution, radiation dosimetry and diagnostic value of 68Ga-AAZTA-NI-093 PET/CT in prostate cancer patients.

Eligibility

Inclusion Criteria:

  • confirmed treated or untreated prostate cancer patients;
  • signed written consent.

Exclusion Criteria:

  • known allergy against PSMA;
  • any medical condition that in the opinion of the investigator may significantly interfere with study compliance.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
