What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Prostate Cancer (PCa) Progression [Restricted Crude Rate Analysis: Number of Participants With PCa Divided by Number of Participants in the Intent-to-Treat (ITT) Population Who Had >=1 Post-baseline Biopsy or Had a Progression

    PC progression (prog.) was defined as the earliest occurrence of primary therapy, also referred to as therapeutic prog., for PC (prostatectomy/radiation/hormonal therapy); or pathological prog., defined as 1 of the following: >=4 cores involved; >=50% of any 1 core involved; or a Gleason pattern of >=4 as a result of any on-study/for-cause biopsy. Primary Gleason grade is assigned to the most common tumor pattern; a second grade to the next most common tumor pattern. The two grades are added together to get a score. Gleason grade= 1-5; Gleason score=2-10; 5 and 10 indicate worst prognosis.

    Measured: Year 1.5 and Overall (Years 0-3)

Secondary outcomes (29)

  1. Number of Participants With Therapeutic Progression

    Primary therapy, also referred to as therapeutic progression, for prostate cancer can be one of the following: prostatectomy, radiation, or hormonal therapy.

    Measured: Year 1.5 and Overall (Years 0-3)

  2. Number of Participants With Pathologic Progression

    Pathological progression is defined as one of the following: >=4 cores involved; >=50% of any 1 core involved; or a Gleason pattern of >=4 as a result of any on-study/for-cause biopsy. The 2005 International Society of Urological Pathologists recommendations for Gleason scoring (GS) were used to grade tumors. A primary grade is assigned to the most common tumor pattern, and a second grade to the next most common tumor pattern. The two grades are added together to get a GS. The Gleason grade=1-5, with 5 having the worst prognosis. The Gleason score=2-10, with 10 having the worst prognosis.

    Measured: Year 1.5 and Overall (Years 0-3)

  3. Participants With at Least One Post-baseline Biopsy With the Indicated Prostate Cancer (PCa) Diagnosis

    All participants were required by protocol to undergo a transrectal ultrasound (TRUS)-guided 12-core prostate biopsy at 1.5 and 3 years or at the end of the study, if the participant discontinued the study early. Any for-cause biopsy (outside of protocol-mandated biopsies) 12 cores were obtained. If a for-cause biopsy occurred within 6 months prior to the protocol-mandated biopsy, the biopsy was counted as the protocol-mandated biopsy. All biopsies were reviewed and analyzed by a central pathologist.

    Measured: Baseline to Month 18

  4. Participants With at Least One Post-baseline Biopsy With the Indicated Prostate Cancer (PCa) Diagnosis for Their Final Biopsy

    All participants were required by protocol to undergo a TRUS-guided 12-core prostate biopsy at 1.5 and 3 years or at the end of the study, if the participant discontinued the study early. Any for-cause biopsy (outside of protocol-mandated biopsies) 12 cores were obtained. If a for-cause biopsy occurred within 6 months prior to the protocol-mandated biopsy, the biopsy was counted as the protocol-mandated biopsy. The final biopsy is defined as the latest post-baseline biopsy for which the results are available from the central pathology laboratory.

    Measured: Years 0-3

  5. Number of Cancer-positive Cores in a 12-core Biopsy

    All participants were required by protocol to undergo a TRUS-guided 12-core prostate biopsy at 1.5 and 3 years or at the end of the study, if the participant discontinued the study early. Any for-cause biopsy (outside of protocol-mandated biopsies) 12 cores were obtained. All biopsies were reviewed and analyzed by a central pathologist. . The final biopsy is defined as the latest post-baseline biopsy for which the results are available from the central pathology laboratory.

    Measured: Baseline, Year 1.5, Year 3, Years 0-3 (Final biopsy)

  6. Change From Baseline in the Number of Cancer-positive Cores in a 12-core Biopsy at Years 1.5, 3, and 0-3

    All participants were required by protocol to undergo a TRUS-guided 12-core prostate biopsy at 1.5 and 3 years or at the end of the study, if the participant discontinued the study early. Any for-cause biopsy (outside of protocol-mandated biopsies) 12 cores were obtained. All biopsies were reviewed and analyzed by a central pathologist. Change from baseline was calculated as the number of cancer-positive cores at post-baseline biopsy minus the number of cancer-positive cores at baseline.

Any for-cause biopsy (outside of protocol-mandated biopsies) 12 cores were obtained. All biopsies were reviewed and analyzed by a central pathologist.

    Measured: Baseline, Year 1.5, Year 3, Years 0-3 (Final biopsy)

  11. Number of Participants With the Indicated Change From Baseline in Gleason Score (GS) on Repeat Biopsy at Year 1.5

    The 2005 International Society of Urological Pathologists recommendations for Gleason scoring were used to grade tumors. A primary grade is assigned to the most common tumor pattern (how the cancer cells look under a microscope), and a second grade to the next most common pattern. The two grades are added together to get a GS. Gleason grade range= 1-5; 5=worst prognosis. GS range=2-10; 10=worst prognosis. Improvement is defined as a decrease in GS from a baseline score of 6 (GS<=6; includes no cancer); worsening is defined as an increase in GS from a baseline score of 6 (GS >6).

    Measured: Year 1.5

  12. Number of Participants With the Indicated Change From Baseline in Gleason Score on Repeat Biopsy at Years 0-3

    The 2005 International Society of Urological Pathologists recommendations for Gleason scoring were used to grade tumors. A primary grade is assigned to the most common tumor pattern (how the cancer cells look under a microscope), and a second grade to the next most common pattern. The two grades are added together to get a GS. Gleason grade range= 1-5; 5=worst prognosis. GS range=2-10; 10=worst prognosis. Improvement is defined as a decrease in GS from a baseline score of 6 (GS<=6; includes no cancer); worsening is defined as an increase in GS from a baseline score of 6 (GS >6).

    Measured: Years 0-3 (Final Biopsy)

  13. Number of Participants With the Indicated Total Gleason Score

    All on-study or for-cause biopsies were reviewed and analyzed by a central pathologist. The 2005 International Society of Urological Pathologists recommendations for Gleason scoring were used to grade the tumor. A primary grade is assigned to the most common tumor pattern (how the cancer cells look under a microscope), and a secondary grade to the next most common tumor pattern. The two grades are added together to get a GS. The Gleason grade ranges from 1 to 5, with 5 having the worst prognosis. The Gleason score ranges from 2 to 10, with 10 having the worst prognosis.

    Measured: Years 0-3 (Final Biopsy)

  14. Number of Biopsies With the Indicated Clinical Tumor Stage at Baseline

    All on-study or for-cause biopsies were reviewed and analyzed by a central pathologist. The 2005 International Society of Urological Pathologists recommendations for clinical tumor staging were used. T1c = tumor identified by needle biopsy (e.g., because of elevated prostate-specific antigen [PSA]); T2 = tumor confined within the prostate; T2a = tumor involves one-half of one lobe, but not both lobes of the prostate.

    Measured: Baseline

  15. Number of Post-baseline Biopsies With the Indicated Change From Baseline in Clinical Stage

    All on-study or for-cause biopsies were reviewed and analyzed by a central pathologist. The National Comprehensive Network (NCCN), 2005 clinical practices guidelines in Oncology-prostate cancer were used for clinical tumor staging. T0: no evidence of primary tumor; T1: clinically inapparent tumor, neither palpable nor visible by imaging; T2: tumor confined within the prostate; T3: tumor extends through the prostate capsule; T4: tumor is fixed or invades adjacent structures other than seminal vesicles. A clinical stage of T0 in post-baseline biopsies has been interpreted as "No Worsening."

    Measured: Months 0-18

  16. Prostate Volume (PV) LOCF

    Prostate volume was determined at baseline, at Year 1.5, and at Year 3. The anteroposterior, cephalocaudal, and transverse diameters of the prostate were obtained by transrectal ultrasound (TRUS) to calculate the prostate volume using the following formula:

    π/ 6 (anteroposterior width * cephalocaudal width * transverse width). Prostate volume calculated by pre-programmed equipment is unacceptable for the on-study prostate volume measurements.

    Measured: Baseline and Years 1.5 and 3

  17. Change From Baseline in Prostate Volume at Years 1.5 and 3

    Prostate volume was determined at baseline, Year 1.5, and Year 3. The anteroposterior, cephalocaudal, and transverse diameters of the prostate were obtained by transrectal ultrasound (TRUS) to calculate the prostate volume using the following formula:

    π/ 6 (anteroposterior width * cephalocaudal width * transverse width). Prostate volume calculated by pre-programmed equipment was unacceptable for the on-study prostate volume measurements.

    Measured: Baseline and Years 1.5 and 3

  18. Percent Change From Baseline in Prostate Volume at Years 1.5 and 3

    Prostate volume was determined at baseline, Year 1.5, and Year 3. The anteroposterior, cephalocaudal, and transverse diameters of the prostate were obtained by transrectal ultrasound (TRUS) to calculate the prostate volume using the following formula:

    π/ 6 (anteroposterior width * cephalocaudal width * transverse width). Prostate volume calculated by pre-programmed equipment is unacceptable for the on-study prostate volume measurements.

    Measured: Baseline and Years 1.5 and 3

  19. Total Memorial Anxiety Scale Scores for Prostate Cancer (MAX-PC)

    The MAX-PC is a self-reported measure evaluating three aspects of PC-related anxiety: general anxiety related to PC/treatment, fear of recurrence, and anxiety related to PSA testing. The MAX-PC consists of 18 questions, each score ranging from 0 (least anxiety) to 3 (maximum anxiety). Total score is the sum of each question score, thus ranging from 0 to 54. A higher MAX-PC score indicates greater anxiety. At Months 18 and 36, participants were given an additional copy of the questionnaire and were asked to complete at home once they were notified of their PSA result and to send back to clinic.

This scale is divided into five subscales: the Physical Well-Being Subscale (7 questions); the Social/Family Well-Being Subscale (7 questions); the Emotional Well-Being Subscale (6 questions); the Functional Well-Being Subscale (7 questions); and the Prostate Cancer Subscale (12 questions). The score for each of the 39 questions ranges from 0 to 4. The total FACT-P score thus ranges from 0 to156; a higher score indicates better quality of life.

    Measured: Baseline and Months 18 and 36

  26. Change From Baseline in Total FACT-P Score (LOCF)

    The FACT-P consists of a total of 39 questions. This scale is divided into five subscales: the Physical Well-Being Subscale (7 questions); the Social/Family Well-Being Subscale (7 questions); the Emotional Well-Being Subscale (6 questions); the Functional Well-Being Subscale (7 questions); and the Prostate Cancer Subscale (12 questions). The questionnaire was administered at baseline and at Months 18 and 36. The score for each of the 39 questions ranges from 0 to 4. The total FACT-P score thus ranges from 0 to156; a higher score indicates better QOL.

    Measured: Baseline and Months 18 and 36

  27. Percent Change From Baseline in Total FACT-P Score (LOCF)

    The FACT-P consists of a total of 39 questions. This scale is divided into five subscales: the Physical Well-Being Subscale (7 questions); the Social/Family Well-Being Subscale (7 questions); the Emotional Well-Being Subscale (6 questions); the Functional Well-Being Subscale (7 questions); and the Prostate Cancer Subscale (12 questions). The questionnaire was administered at baseline and at Months 18 and 36. The score for each of the 39 questions ranges from 0 to 4. The total FACT-P score thus ranges from 0 to156; a higher score indicates better QOL.

    Measured: Baseline and Months 18 and 36

  28. Change From Baseline in FACT-P Physical Well-Being Subscale Score (LOCF)

    The FACT-P Physical Well-Being subscale is divided into 7 questions, and the participants rated the outcome over the past 7 days; "I have a lack of energy.", "I have nausea.", "Because of my physical condition, I have trouble meeting the needs of my family.", "I have pain.", "I am bothered by side effects of treatment.", "I feel ill.", "I am forced to spend time in bed." The score for each question ranges from 0 to 4; a lower score indicates better physical well-being. The total FACT-P score thus ranges from 0 to156; a higher score indicates a better quality of life.

    Measured: Baseline and Months 18 and 36

  29. Change From Baseline in FACT-P Social Well-Being Subscale Score (LOCF)

    The FACT-P Social Well-Being subscale is divided into 7 questions, and the participants rated the outcome over the past 7 days; "I feel close to my friends.", "I get emotional support from my family.", "I get support from my friends.", "My family has accepted my illness.", "I am satisfied with family communication about my illness.", "I feel close to my partner (or the person who is my main support).", "I am satisfied with my sex life." The score for each question ranges from 0 to 4; a higher score indicates better social well-being. The total FACT-P score thus ranges from 0 to 156.

    Measured: Baseline and Months 18 and 36

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dutasteride in people with Neoplasms, Prostate, run by GlaxoSmithKline at 82 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 82 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Jun 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Prostate Cancer (PCa) Progression [Restricted Crude Rate Analysis: Number of Participants With PCa Divided by Number of Participants in the Intent-to-Treat (ITT) Population Who Had >=1 Post-baseline Biopsy or Had a Progression (time frame: Year 1.5 and Overall (Years 0-3)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00363311, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jan 2017; AzTrials last refreshed its copy on 8 Nov 2026.
