Further study details as provided by GP-Pharm:

Primary Outcome Measures:
  • Efficacy: to determine the proportion of patients achieving castration levels of plasma testosterone (defined as <0.5 ng/mL) 4 weeks after the first administration
  • to determine the proportion of patients maintaining castration levels of plasma testosterone from week 4 to study end
  • to determine the proportion of patients showing acute rises in plasma testosterone levels upon repeated dosing from week 4 to study end
  • Safety: evaluation of the safety of the new formulation based on adverse events (AEs), local tolerability, vital signs, electrocardiograms (ECGs), and clinical parameters

Secondary Outcome Measures:
  • Efficacy: determination of serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prostate-specific antigen (PSA) concentrations
  • World Health Organization/Eastern Cooperative Oncology Group (WHO/ECOG) performance status, bone pain, urinary symptoms and urinary pain after administration

Estimated Enrollment: 120
Study Start Date: September 2005
Study Completion Date: November 2007
Detailed Description:

Other assessments include evaluation of main leuprolide PK parameters in 12 subjects after administration of 3 doses.

Study Design:

This will be a multi-center, open-label, fixed investigation of six monthly dosages of leuprolide acetate 3.75 mg administered to patients with histologically proven carcinoma of prostate, who might benefit from medical androgen deprivation therapy.

A total of 120 male patients will receive a single, i.m. injection of leuprolide acetate 3.75 mg initially on study day 0 (after baseline assessment) and then monthly (i.e. every 28 days) for five months.

12 of the patients will also have plasma leuprolide levels measured for PK analysis during the first 3 injection periods (PK group). These patients will belong to pre-defined study sites.

  Eligibility

Ages Eligible for Study:   18 Years and older

  • Adequate renal function at screening as defined by serum creatinine </= 1.6 times the ULN (upper limit of normal) for the clinical laboratory
  • Adequate and stable hepatic function as defined by bilirubin </= 1.5 times the ULN and transaminases (i.e. SGOT, SGPT) </= 2.5 times the ULN for the clinical laboratory at screening
  • Ability to comprehend the full nature and purpose of the study, including possible risks and side effects; ability to co-operate with the Investigator and to comply with the requirements of the entire study

  • Testosterone levels < 1.5 ng/mL at screening, locally determined at the laboratory of each clinical site
  • Previous cancer systemic therapy such as chemotherapy, immunotherapy (e.g. antibody therapies, tumor-vaccines), biological response modifiers (e.g. cytokines) within 3 months of baseline
  • Previous hormonal therapy for treatment of prostate cancer, such as luteinising hormone-releasing hormone (LHRH) analogues (e.g. Lupron®, Zoladex®, etc.) [no wash-out allowed]
  • Previous treatment with androgen receptor (AR) blockers, such as Casodex®, Fugerel®, Megace®, Androcur® (no wash-out allowed)
  • Previous orchiectomy, adrenalectomy or hypophysectomy
  • Previous prostatic surgery (e.g. radical prostatectomy, transurethral resection of the prostate [TUR-P]) within 2 weeks of baseline
  • Previous local therapy to the primary tumor with a curative attempt other than surgery (external beam radiotherapy, brachytherapy, thermotherapy, cryotherapy) within 2 weeks of baseline
  • Any investigational drug within 5 half-lives of its physiological action or 3 months (whichever is longer) before baseline
  • Administration of 5-alpha-reductase inhibitors (Proscar®, Avodart®, Propecia®) within 3 months before baseline
  • Over-the-counter (OTC) or alternative medical therapies which have an estrogenic or anti-androgenic effect (i.e., PC-SPES, saw palmetto, Glycyrrhiza®, Urinozinc®, dehydroepiandrosterone [DHEA]) within the 3 months before baseline
  • Hematological parameters (RBC, total and differential WBC count, platelet count, hemoglobin, hematocrit) outside 20% of the upper or lower limits of normal (ULN, LLN) for the clinical laboratory at screening
  • Co-existent malignancy, according to the Investigator's opinion
  • Uncontrolled congestive heart failure, myocardial infarction or a coronary vascular procedure (e.g. balloon angioplasty, coronary artery bypass graft) or significant symptomatic cardiovascular disease(s) within 6 months before baseline; resting uncontrolled hypertension: (>/= 160/100 mmHg) or symptomatic hypotension within 3 months before baseline

  • History of drug and/or alcohol abuse within 6 months of baseline
  • Serious concomitant illness(es) or disease(s) [e.g., hematological, renal, hepatic, respiratory, endocrine, psychiatric] that may interfere with, or put patients at additional risk for, their ability to receive the treatment outlined in the protocol
  • Patients receiving anticoagulants who have prothrombin and partial thromboplastin times outside of the normal range for the laboratory assays; patients who are on anticoagulation or antiplatelet medications (e.g. dipyridamole, ticlopidine, warfarin derivatives) who are not receiving a stable dose for 3 months before baseline; patients who are receiving warfarin-derivative anticoagulants who do not have an International Normalized Ratio (INR) in the therapeutic range for the clinical indication for which the anticoagulant has been prescribed.
  • Blood donations/losses within 2 months of baseline, apart from previous prostatic surgery patients (see earlier exclusion [9]; please note that these patients should not be included in the pharmacokinetic [PK] group)
