Registered outcomes6

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryChange From Baseline in the Serum Prostate Specific Antigen (PSA) LevelBaseline and 3 months after initial treatmentEfficacy: Change from Baseline in the serum PSA level from baseline and 3 months Change = Month 3 minus Baseline value
SecondaryChange From Baseline in the Void Volume (VV)Baseline and 3 months after initial treatmentEfficacy: Change from Baseline in the Void Volume (VV) from baseline and 3 months Change = Month 3 minus Baseline value
SecondaryChange From Baseline in the Maximum Flow Rate (Qmax)Baseline and 3 months after initial treatmentEfficacy: Change from Baseline in the maximum flow rate (Qmax) from baseline and 3 months Change = Month 3 minus Baseline value
SecondaryChange From Baseline in the IPSS Subscore (IPSS Voiding) QuestionnairesBaseline and 3 months after initial treatment
Efficacy: Change from Baseline in the IPSS Voiding from baseline and 3 months. The IPSS subscore (IPSS Voiding) questionnaires is a 4 symptom questions. The symptom score have 6-point scale ranging from 0 "Not at all" to 5 "Almost always". Each question is assigned points from 0 to 5 indicating increasing severity of the particular symptom. The total IPSS Voiding score can therefore range from 0 to 20 (asymptomatic to very symptomatic). Change = Month 3 minus Baseline value
SecondaryChange From Baseline in the IPSS Subscore (IPSS Storage) QuestionnairesBaseline and 3 months after initial treatment
Efficacy: Change from Baseline in the IPSS Storage from baseline and 3 months The IPSS subscore (IPSS Storage) is a 3 symptom questions. The symptom score have 6-point scale ranging from 0 "Not at all" to 5 "Almost always". Each question is assigned points from 0 to 5 indicating increasing severity of the particular symptom. The total IPSS Storage score can therefore range from 0 to 15 (asymptomatic to very symptomatic). Change = Month 3 minus Baseline value
SecondaryChange From Baseline in the International Prostate Symptom Score (IPSS) QuestionnairesBaseline and 3 months after initial treatment
Efficacy: Change from Baseline in the International Prostate Symptom Score (IPSS) from baseline and 3 months The International Prostate Symptom Score (IPSS) is an 7 symptom questions including 4 voiding questions (IPSS Voiding), 3 storage questions (IPSS Storage) The symptom score have 6-point scale ranging from 0 "Not at all" to 5 "Almost always". Total IPSS score = IPSS voiding + IPSS Storage Rang = 0 to 35 (asymptomatic to very symptomatic). Mild = 0 to 7; Moderate = 8 to 19; Severe = 20 to 35 Change = Month 3 minus Baseline value
