    Drug: 212Pb-NG001

Interventions

  • Drug212Pb-NG001

    212Pb-NG001 is a targeted alpha-emitting radiopharmaceutical conjugated to a PSMA targeting peptide. Patients will receive an initial single 10 MBq dose IV to explore the imaging potential of 212Pb-NG001.

What researchers measure

Primary outcomes

  1. Feasibility of SPECT/CT gamma camera imaging for uptake of 212Pb-NG001

    To qualitatively determine whether 212Pb-NG001 can be used to produce images of sufficient clarity and sensitivity by SPECT/CT to confirm 212Pb-NG001 uptake and biodistribution.

    Time frame: Up to 28 days

Secondary outcomes

  1. Safety and tolerability

    Number of participants with treatment-related adverse events as assessed by CTCAE v5.0

    Time frame: Up to 28 days

  2. Body clearance

    To study body clearance of 212Pb-NG001 by gamma camera imaging and by sample and probe measurements.

    Time frame: Up to 2 days

  3. Therapeutic effect on prostate cancer as indicated by decreasing serum PSA and/or ALP

    To explore any signals of therapeutic effects on the laboratory parameters: prostate specific antigen (PSA) and alkaline phosphatase (ALP)

    Time frame: Up to 28 days
