Phase of TrialPhase 2

Trial summary

This phase 2 randomised clinical trial will compare the effectiveness of Lu-PSMA therapy
followed by docetaxel chemotherapy versus docetaxel chemotherapy on its own in patients with
newly-diagnosed high-volume metastatic hormone-naive prostate cancer (mHNPC).

         -  Aspartate transaminase (AST) or alanine transaminase (ALT) = 2.0 x ULN (or = 5.0
            x ULN in the presence of liver metastases)

    8. Have a performance status of 0-2 on the ECOG Performance Scale (see Appendix 1)

  Exclusion Criteria for Registration:

    1. Any prior pharmacotherapy, radiation therapy, or surgery for metastatic prostate
       cancer. The following exceptions are permitted:

         -  Up to 4 weeks of ADT with luteinising hormone releasing hormone agonists or
            antagonists or orchiectomy ± concurrent anti-androgens are permitted prior to
            commencement of screening. At investigator discretion, patients may start ADT at
            commencement of protocol therapy

         -  Up to one course of palliative radiation or surgical therapy to treat symptoms
            resulting from metastatic disease if it was administered at least 14 days prior
            to registration

    2. Symptomatic cord compression, or clinical or imaging findings concerning for impending
       cord compression

    3. Central nervous system metastases

    4. Patients with Sjogren's syndrome

    5. Has a history or current evidence of any condition, therapy, or laboratory abnormality
       that might confound the results of the trial, interfere with the patient's
       participation for the full duration of the trial, or is not in the best interest of
       the patient to participate, in the opinion of the treating investigator

    6. Prior diagnosis of another cancer that was:

         -  More than 3 years prior to current diagnosis with subsequent evidence of disease
            recurrence or clinical expectation of recurrence greater than 10%

         -  Within 3 years of current diagnosis with the exception of successfully treated
            basal cell or squamous cell skin carcinoma or adequately treated non-muscle
            invasive bladder cancer (Tis, Ta and low grade T1 tumours)

  Inclusion Criteria for Randomisation:

    1. Significant PSMA avidity on 68Ga-PSMA PET/CT, defined after central review as a
       minimum uptake of SUVmax 15 at a site of disease

    2. High-volume metastatic disease on 68Ga-PSMA PET/CT defined as visceral metastases or =
       4 bone metastases with = 1 outside the vertebral column and pelvis (extra-axial

    3. Patient continues to meet all the inclusion criteria for registration

  Exclusion Criteria for Randomisation:

    1. Major FDG-PET discordance defined as presence of FDG positive disease with minimal
       PSMA expression in multiple sites (>5) or in more than 50% of total disease volume

    2. All the exclusion criteria for registration continue to not apply
