A Study to Track the Safety of Vesomni in Men in South Korea Treated in Routine Clinical Practice for the Urinary Symptoms of Benign Prostatic Hyperplasia (Enlarged Prostate)

Benign prostatic hyperplasia (BPH), also known as an enlarged prostate, happens more often in men as they age. This condition causes a sudden need to pass urine, which is hard to control. Men with an enlarged prostate may need to pass urine many times during the day and night which can affect their wellbeing. There are treatments available, like tamsulosin but they don't work well in some men and can cause further health problems. Vesomni is approved in South Korea to treat urinary symptoms in men with an enlarged prostate, when treatment with tamsulosin doesn't work well enough.

This study will track the safety of Vesomni given to men in South Korea who have moderate to severe symptoms from an enlarged prostate, who have previously been treated with tamsulosin and found it didn't work well. The safety of Vesomni is tracked by mainly collecting information from their medical records. The sponsor will ask for extra information to be collected, and if any health problems were caused by Vesomni. In this study, researchers want to learn about the safety of Vesomni and how well it controls symptoms in men with an enlarged prostate.

The men's own doctor decides on treatment, as part of routine clinical practice, not the sponsor (Astellas). This study is about collecting information only. Most information about the safety and control of symptoms will be collected from medical records. The sponsor will also ask for extra information to be collected. All information will be collected for up to 24 weeks after the men start treatment with Vesomni.

About this study

Primary data collection will occur during the observation period for each participant, targeted for 12 weeks (or at least 24 weeks for long-term users) after receiving the first dose of Vesomni. Secondary data collection (extracting data from medical records, including hospital admission/discharge notes, prescription drug files, biological measurements, etc.) will occur for participants enrolled.

Primary outcomes

  1. Number of Participants With Adverse Events (AEs) or Adverse Drug Reactions (ADR)

    Time frame: Up to 24 Weeks

    An AE is defined as any untoward medical occurrence in a participant administered a study drug, and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product whether or not considered related to the medicinal (investigational) product.

    An ADR is defined as any noxious and unintended response associated with the use of a drug in humans, at any dose, where a causal relationship is at least a reasonable possibility.

  2. Number of Participants With Serious AE (SAE)/ Serious ADR (SADR)

    Time frame: Up to 24 Weeks

    An AE is considered "serious" if it results in death or life-threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, is a medically important event or reaction

  3. Number of Participants With an Unexpected AE (UAE)/ Unexpected ADR (UADR)

    Time frame: Up to 24 Weeks

    An UAE is an AE that the nature or severity of which is not consistent with the information described in the approved Korean product label

  4. Number of Participants With Important Risks

    Time frame: Up to 24 Weeks

    An important risk is classified as either an important identified risk and/or an important potential risk.

    An "Important Identified Risk" refers to an undesirable clinical outcome, with sufficient scientific evidence through clinical trials or post-marketing data to confirm that the undesirable clinical outcome is caused by the drug, and which have the potential to affect the risk-benefit balance of a product.

    An "Important Potential Risk" refers to an undesirable clinical outcome, with some, but not sufficient, evidence to confirm that the undesirable clinical outcome is caused by the drug. These risks may have the potential to affect the risk-benefit balance of a product, and therefore require ongoing monitoring and assessment.

Secondary outcomes

  1. Changes From Baseline in Total Score of the International Prostate Symptom Score (IPSS)

    Time frame: Baseline, Week 12 and 24

    The IPSS is used to evaluate the degree of "bother" from urinary symptoms, based on answers to 7 questions concerning urinary symptoms related to BPH, and 1 additional question assessing the impact of these symptoms on the patient's QoL. Each of the 7 symptom questions is scored from 0 to 5, indicating increasing severity of the symptom, with a total score ranging from 0 to 35.

  2. Change From Baseline in Storage Subscore of IPSS

    Time frame: Baseline, Week 12 and 24

    The IPSS is used to evaluate the degree of "bother" from urinary symptoms, based on answers to 7 questions concerning urinary symptoms related to BPH, and 1 additional question assessing the impact of these symptoms on the patient's QoL. The storage sub-score of the IPSS, which is calculated from the frequency, urgency, and nocturia sections of the IPSS total score, is used to evaluate the degree of urinary storage symptoms related to BPH. Each question in the storage sub-score is scored from 0 to 5, indicating increasing severity of the symptom, with a total score range from 0 to 15.

  3. Change From Baseline in Quality of Life (QoL) Score of IPSS

    Time frame: Baseline, Week 12 and 24

    The IPSS is used to evaluate the degree of "bother" from urinary symptoms, based on answers to 7 questions concerning urinary symptoms related to BPH, and 1 additional question assessing the impact of these symptoms on the patient's QoL. The QoL question is scored separately on a scale from 0 (delighted) to 6 (terrible), reflecting the patient's subjective satisfaction with their urinary condition.
