E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary objective: to evaluate the effect of tryptophan supplementation on lower urinary tract symptoms (LUTS) as assessed by the International Prostate Symptom Score (IPSS) on patients with known BPH. |
Objetivo Primário: avaliar o efeito da suplementação com triptofno nos sintomas do trato urinário inferior, medidos através do International Prostate Symptom Score (IPSS) em pacientes com Hiperplasia Benigna da Próstata (HBP) conhecida. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the effect of tryptophan supplementation on secondary endpoints, including changes in urine maximum flow rate (Qmax), prostate volume, assessed by trans-rectal ultra-sound, and erectile function, assessed by International Index of Erectile Function-5 (IIEF-5) and in quality of life due to urinary symptoms (question 8 of the IPSS). |
Avaliar o efeito da suplementação com triptofano nos endpoints secundários, incluindo alterações na velocidade máxima de micção (Qmax), do volume da próstata, avaliado pelo ultrassom transrectal, da função eréctil avaliada pelo International Index of Erectile Function-5 (IIEF-5) e na qualidade de vida devido aos sintomas urinários (questão 8 do IPSS). |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Written informed consent must be obtained before any assessment is performed; • Male patients with BPH for which tamsulosin is the therapeutic option per SoC; • Aged ≥50 and less than 75 years old; • With prostate volume ≥30 cm3 by TRUS (23); • Diagnosed with LUTS defined by a stable IPSS total score ≥13 points;
|
• Consentimento informado escrito tem de ser obtido antes de realizar qualquer procedimento; • Pacientes homens com HBP para os quais a tansulosina seja a opção terapêutica por prática clínica; • Com 50 ou mais anos e menos de 75 anos de idade; • Com volume da próstata volume ≥30 cm3 pelo TRUS; • Diagnosticado com sintomas do trato urinário inferior, definido com um score IPSS estável de ≥13 pontos;
|
|
E.4 | Principal exclusion criteria |
• patients with postvoid bladder residual volume ≥250 ml; • patients with intravesical obstruction from any cause other than BPH; • history of any procedure considered an intervention for BPH; • patients with active urinary tract infection; • history of recurrent urinary tract infections; • current prostatitis or diagnosis of chronic prostatitis; • history of prostate or invasive bladder cancer; • use of 5 α-reductase inhibitors within 6 months; • phytotherapy within 2 weeks before entry; • use of serotonin reuptake inhibitors or monoamine oxidase inhibitors. • patients with acute or chronic kidney failure; • patients with diagnosed or suspicion of intolerance to lactose; • patients submitted to general anesthesia in the past 4 weeks. • Known intellectual disability that may hampers giving informed consent and would make the patient inappropriate for entry into this study, in the judgment of the investigator. |
• Pacientes com volume residual da bexiga pós-micção ≥250 ml; • Pacientes com obstrução intravesical por qualquer outra causa que não seja HBP; • História de qualquer procedimento interventivo para HBP; • Pacientes com infeção ativa do trato urinário; • História de infeções recorrentes do trato urinário; • Prostatite atual ou diagnóstico de prostatite crónica; • História de cancro da próstata ou invasivo da bexiga; • Uso de inibidores da 5 α-redutase nos últimos 6 meses; • Fitoterapia nas 2 semanas anteriores à inclusão no estudo; • Uso de inibidores da recaptação da serotonina ou inibidores da monoaminoxidase; • Pacientes com insuficiência renal aguda ou crónica; • Pacientes com diagnóstico ou suspeita de intolerância à lactose; • Pacientes submetidos a anestesia geral nas últimas 4 semanas; • Incapacidade intelectual conhecida que possa condicionar a capacidade de dar consentimento informado e que, na opinião do investigador, torne a inclusão do participante no estudo inapropriada. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary goal of the study is to demonstrate the superiority of tryptophan to tamsulosin for the improvement of LUTS associated with BPH. This will be measured by a change from baseline in the total score (questions 1–7) of the IPSS questionnaire. |
O objetivo primário do estudo é demostrar a superioridade do triptofano em relação à tansulosina na melhoria dos sintomas do trato urinário inferior associados com a HBP. Isto será medido pela alteração do nível basal no score total (questões 1-7) do questionário IPSS. |

|
E.5.2 | Secondary end point(s) |
There are three secondary efficacy endpoints: • Urine maximum flow rate (Qmax); • Erectile function, assessed by International Index of Erectile Function-5 (IIEF-5); • Prostate volume (in cc), assessed by trans-rectal ultra-sound; • Quality of life due to urinary symptoms (question 8 of the IPSS). |
Há 4 endpoints secundários da eficácia: • Velocidade máxima de micção (Qmax): • Função eréctil, avaliada pelo International Index of Erectile Function-5 (IIEF-5); • Volume da Próstata (em cc), avaliado pelo ultrassom transrectal; • Qualidade de vida associada aos sintomas urinários (questão 8 do IPSS).
