Brief Summary:

This study is a multinational Phase 3, randomized, double-blind, non-inferiority, efficacy and safety study of oral HC-1119 (80 mg/day) versus enzalutamide (160 mg/day) in asymptomatic or mildly symptomatic patients with progressive metastatic castration-resistant prostate cancer (mCRPC).

The following assessment of prostate cancer status will be collected during the course of the trial: soft tissue disease on computed tomography (CT) scan or on magnetic resonance imaging (MRI), bone disease on radionuclide bone scans, FACT-P and EQ-5D, Brief Fatigue Inventory, and PSA.

Throughout the study, safety and tolerability will be assessed by the recording of adverse events, monitoring of vital signs and physical examinations, safety laboratory evaluations, and 12-lead electrocardiograms (ECGs). Blood samples for population pharmacokinetics for HC-1119 and enzalutamide and related metabolites will be collected.

Prostate Cancer Metastatic Castration-resistant Prostate Cancer Drug: HC-1119 Drug: Enzalutamide Phase 3

Detailed Description:

This study is a multinational Phase 3, randomized, double-blind, non-inferiority, efficacy and safety study of oral HC-1119 (80 mg/day) versus enzalutamide (160 mg/day) in asymptomatic or mildly symptomatic patients with progressive metastatic castration-resistant prostate cancer (mCRPC). Patients must not have been previously treated with next generation AR-Inhibitors or Androgen-biosynthesis Inhibitors, or prior progression on ketoconazole.

The following assessments of prostate cancer status will be collected during the course of the trial: soft tissue disease on computed tomography (CT) scan or on magnetic resonance imaging (MRI), bone disease on radionuclide bone scans, FACT-P and EQ-5D, Brief Fatigue Inventory, and PSA. Radiographic disease progression is defined by the Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST 1.1) for soft tissue disease, or the appearance of two or more new bone lesions on bone scan.

Throughout the study, safety and tolerability will be assessed by the recording of adverse events, monitoring of vital signs and physical examinations, safety laboratory evaluations, and 12-lead electrocardiograms (ECGs). Blood samples for population pharmacokinetics for HC-1119 and enzalutamide and related metabolites will be collected pre-dose on Day 1 and prior to dosing on Days 8 (Week 2), 15 (Week 3) and 22 (Week 4), 29 (Week 5), 57 (Week 9), 85 (Week 13) and Day 169 (Week 25). Blood samples for calculating a 24 hour pharmacokinetic profile of HC-1119 and enzalutamide and related metabolites will be collected in a subset of 24 Caucasian (non-Chinese) patients on Day 1 and at steady state in week 9.

Patients will have a safety follow-up visit 30 days after their last dose of study drug or prior to initiation of any new therapy, or an investigational agent, whichever occurs first.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

Subjects must meet the following inclusion criteria:

  1. Age 18 or older and willing and able to give informed consent.
  2. Histologically or cytologically confirmed adenocarcinoma of the prostate without significant and relevant neuroendocrine differentiation or small cell features, per investigator's judgment.
  3. Ongoing ADT with a GnRH analogue, antagonist or bilateral orchiectomy (i.e., surgical or medical castration).
  4. For patients who have not had a bilateral orchiectomy, there must be a plan to maintain effective GnRH analogue or antagonist therapy for the duration of the trial.
  5. Serum testosterone level < 1.7 nmol/L (50 ng/dL) at the Screening visit.
  6. Patients receiving bisphosphonate or denosumab therapy must have been on stable doses for at least four weeks (from Day 1 visit).
  7. Progressive disease at study entry defined as one or more of the following three criteria that occurred while the patient was on ADT as defined in eligibility criterion #3:

    1. PSA progression defined by a minimum of two rising PSA levels with an interval of ≥ 1 week between each determination. Patients who received an anti-androgen agent must have progression after withdrawal (≥ 4 weeks since last flutamide or ≥ 6 weeks since last bicalutamide or nilutamide). The PSA value at the Screening visit should be ≥ 2 µg/L (2 ng/mL)
