Phase I/IIa Dose Escalation and Toxicity Study of [212Pb]Pb-ADVC001 in Metastatic Prostate Adenocarcinoma (TheraPb – Phase I/II)

ACTRN 12622001378718

Brief Summary

The aim of this study is to determine the maximum safe and effective dose of a novel therapeutic ADVC001 complexed with the radio-isotope alpha-212 ([212Pb]Pb-ADVC001) for the treatment of metastatic prostate cancer.

Intervention/Treatment

  • Drug: [212Pb]Pb-ADVC001

Inclusion Criteria

  1. Male aged 18 years or older with metastatic adenocarcinoma of the prostate, defined by documented histopathology of prostate adenocarcinoma or metastatic disease typical of prostate cancer (i.e. Involving bone or pelvic lymph nodes or para-aortic lymph nodes).
  2. Patients with castration-resistant prostate cancer that have received at least one cycle of androgen receptor therapy and exposure to a taxane-based chemotherapy unless considered contraindicated by a medical oncologist or patient declines treatment.
  3. Progressive disease with rising PSA level, or new lesion(s) in the viscera or lymph nodes as per RECIST 1.1 or in bone as per Prostate Cancer Working Group 3.
  4. Significant PSMA avidity on [68Ga]Ga-PSMA PET/CT.
  5. ECOG Performance status 0 to 2.
  6. Adequate renal, bone and liver function (Absolute neutrophil count: greater than or equal to 2 x 109 /L , Hemoglobin: greater than or equal to 90 g/L, Platelet count: greater than or equal to 150,000 x 109/L, Serum creatinine: less than 1.5 x upper limit of normal (ULN) i.e = 125 umol/L or calculated creatinine clearance greater than or equal to 60 mL/min/1.73 m2 by Cockcroft-Gault formula, Serum total bilirubin: less than 1.5 x ULN (unless the patient has Gilbert’s syndrome in which case direct bilirubin must be normal), Serum AST and ALT: less than 1.5 x ULN in the absence of liver metastases; less than 3 x ULN if due to liver metastases (in both circumstances bilirubin must meet entry criteria).
  7. Estimated life expectancy greater than 12 weeks.
  8. Willing and able to comply with all study requirements, including the timing and nature of all required assessments (i.e. blood testing and scanning.).
  9. Have provided written Informed Consent for participation in this trial.
