Brief Summary

This is a multicenter, correlative study to existing Lutetium based prostate-specific membrane antigen (PSMA)-targeted radioligand therapy (RLT) trials and uses.

Detailed Description

PRIMARY OBJECTIVES: I. To determine the relationship between whole body tumor absorbed dose and response Lutetium based prostate-specific membrane antigen-targeted radioligand therapy (177Lu-PSMA-RLT...

Eligibility Criteria

Inclusion

  • Initiating treatment with Lutetium based PSMA-targeted RLT.
  • Participants must have a PSMA-avid lesion that is accessible to biopsy. Biopsy of newly emerging radiographic metastases is desired and preferable to the biopsy of previously existing lesions whenever possible. Newly emerging lesions are defined as those that are absent on a previous scan, or those demonstrating unequivocal progression since initiation of the last treatment. Biopsies will be performed according to local institutional standards.
  • Patients on warfarin, aspirin, or other anti-coagulants are eligible provided they are deemed able to tolerate discontinuation of anti-coagulation for at least five days prior to the biopsy. Conversion to low molecular weight heparin prior to biopsy is permitted per local standard operating procedures, provided there is approval by the interventional radiologist or the PI.
  • Age \>=18 years.
  • Ability to understand and the willingness to sign a written informed consent document.

Exclusion

  • Patients with significant congenital or acquired bleeding disorders (eg von Wildebrand's disease, acquired bleeding factor inhibitors).
  • Patients who are not able to undergo additional study related imaging procedures.
