What is being measured

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

  1. Change From Baseline to 12 Week Endpoint in International Prostate Symptom Score (IPSS): Primary Analysis

    Assesses the severity of BPH-LUTS and the response to therapy. The total score was derived by summing the scores of the responses to the 7 component questions. Scores range from 0 to 35; 0-7 Mildly symptomatic; 8-19 moderately symptomatic; 20-35 severely symptomatic.

    Measured: Baseline and 12 weeks

  2. Change From Baseline to Week 12 in International Prostate Symptom Score (IPSS): Supportive Analysis

    Assesses the severity of BPH-LUTS and the response to therapy. The total score was derived by summing the scores of the responses to the 7 component questions. Scores range from 0 to 35; 0-7 Mildly symptomatic; 8-19 moderately symptomatic; 20-35 severely symptomatic.

    Measured: Baseline and 12 weeks

Secondary outcomes (8)
  1. Change From Baseline to 12 Week Endpoint in International Prostate Symptom Score (IPSS) (Irritative) Subscore

    Measures irritative symptoms over the past 4 weeks of the IPSS. IPSS irritative subscore is the sum of Questions 2, 4 and 7 of the IPSS questionnaire. Scores range from 1 (few irritative symptoms) to 5 (frequent irritative symptoms), thus the 3 questions of the irritative subscore range from 0 to 15.

    Measured: baseline and 12 weeks

  2. Change From Baseline to 12 Week Endpoint in International Prostate Symptom Score (IPSS) Voiding (Obstructive) Subscore

    Measures obstructive symptoms over the past 4 weeks of the IPSS. IPSS obstructive subscore is the sum of Questions 1, 3, 5 and 6 of the IPSS questionnaire. Scores range from 1 (few obstructive symptoms) to 5 (frequent obstructive symptoms), thus the 4 questions of the obstructive score range from 0 to 20.

    Measured: 12 weeks

  3. Change From Baseline to 12 Week Endpoint in International Prostate Symptom Score (IPSS) Question 7 (Nocturia)

    Measures nocturia (the need to get up at night to urinate) over the past 4 weeks. Scores range from 1 (few episodes of nocturia) to 5 (frequent episodes of nocturia).

    Measured: baseline and 12 weeks

  4. Change From Baseline to 12 Week Endpoint in International Prostate Symptom Score (IPSS) Quality of Life (QoL) Index

    Assessment of quality of life (QOL) by urinary symptoms, with scores ranging from 0 (delighted) to 6 (terrible).

    Measured: baseline and 12 weeks

  5. Change From Baseline to 12 Week Endpoint in Benign Prostatic Hyperplasia Impact Index (BII)

    Measures the impact that symptoms of BPH has on the patients well being. This questionnaire has 4 questions assessing the level of urinary discomfort and it's impact on the patients. Three questions range from 0 (no impact) to 4 (high impact); one question ranges from 0 (low impact) to 4 (high impact). The BII score ranges from 0 to 16.

    Measured: baseline and 12 weeks

  6. Number of Participants Who Answer "Yes" to the Lower Urinary Tract Symptoms (LUTS) Global Assessment Question (LUTS-GAQ)

    LUTS-GAQ Question asks the participant if the treatment they have been on has improved their uninary symptoms.

    Measured: 12 weeks

  7. Change From Baseline to 12 Week Endpoint in Peak Urinary Flow

    Measures the maximum flow rate of urine (measured in mL/s). This is a continuous parameter with positive numeric values.

    Measured: baseline and 12 weeks

  8. Change From Baseline to 12 Week Endpoint in International Index of Erectile Function (IIEF) EF Domain

    Measures erectile function over the past 4 weeks on Questions 1-5 and 15 (6 questions) of the International Index of Erecile Function (IIEF) questionnaire. Scores range from 0 (low/no erectile function) to 5 (high erectile function), thus the 6 questions of the IIEF-EF domain range from 0 to 30.

    Measured: baseline and 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing tadalafil in people with Benign Prostatic Hyperplasia, run by Eli Lilly and Company at 1 site in United States.

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 4 inclusion and 5 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 2 Sep 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 19 Aug 2009). 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?

Change From Baseline to 12 Week Endpoint in International Prostate Symptom Score (IPSS): Primary Analysis (time frame: Baseline and 12 weeks). The study lists 2 primary outcomes in all. 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 NCT00384930, which also lists 4 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 2 Sep 2009.
