Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will involve performing Lutetium-177 (177Lu)-prostate-specific membrane antigen (LuPSMA) treatment as an adjunct to standard care (prostatectomy) in patients with newly diagnosed high-risk PSMA-expressing prostate cancer.
LuPSMA is a novel and highly targeted systemic radioligand therapy for progressive metastatic castration-resistant prostate cancer.
Patients will undergo one LuPSMA treatment 8.0–9.0 +/- 10% GBq activity administered
via a dedicated radionuclide therapy pump (RadInject, Tema Sinergie, Italy) over 10 minutes under the supervision of a Nuclear Medicine Radiologist and a Technologist.
This is followed by prostatectomy surgery within 1-2 weeks after LuPSMA treatment.
Patients will undergo a second dose of LuPSMA treatment 8-10 weeks after prostatectomy.
Patients will undergo two, single doses of LuPSMA in total by intravenous infusion.

Eligibility
Key inclusion criteria
Newly diagnosed high-risk prostate-specific membrane antigen (PSMA)-expressing prostate cancer defined as International Society of Urological Pathologists grade of 5 or Gleason score of 9 or 10, and a minimum standard uptake value of 10 on digital Gallium-68 (Ga68)-PSMA positron emission tomography/computed tomography (PET/CT).
Patient must be scheduled for a prostatectomy with a Wesley surgeon.

Other inclusion criteria is standard for this treatment at our site.
Inclusive of:
• Referrals for LuPSMA therapy are accepted from Medical Oncologists, Radiation Oncologists or Urologists. On referral, each patient is discussed at a multi-disciplinary team meeting to ensure that there is consensus on the appropriateness of LuPSMA therapy.
• To confirm suitability for treatment, a Ga68-PSMA PET/CT with diagnostic-quality CT demonstrating PSMA-avid disease is required.
• Laboratory tests are required to demonstrate; (i) baseline serum prostate-specific antigen (PSA) level, (ii) a full blood count showing acceptable haemoglobin (at least 90 g/L), neutrophil (at least 1.5 x 10^9/L) and platelet (at least 75 x 10^9/L) values, (iii) renal function without impairment (estimated glomerular filtration rate (eGFR) at least 40 mL/min), and (iv) liver function without impairment (albumin at least 25 g/L). Laboratory test results are used as a guide only, with exceptions made on a case-by-case basis.
• A nuclear medicine renal scan with technetium-99 m mercaptoacetyltriglycine (99mTc-MAG3) is required if there is evidence of renal obstruction or impairment on the diagnostic-CT component of the Ga68-PSMA PET/CT or eGFR test.
