A Single-Arm, Dose Escalation of an Intraurethral Alprostadil Paste for Erectile Dysfunction

This is a single arm dose escalation trial of a mucoadhesive intraurethral polymer suspension of alprostadil (ST-04) and will investigate the efficacy of 3 dose levels of ST-04 in adult males with a clinical diagnosis of Erectile Dysfunction (ED). This study aims to determine if ST-04, with or without sildenafil, will improve erectile function (EF) compared to baseline. Participants in this study will receive ST-04, a new formulation containing the vasodilator, alprostadil which is known to be an effective drug in treating erectile dysfunction. ST-04 will be dispersed along the urethra, forming a hydrogel which adheres to the lining of the urethra with the goal of penile tumescence and erection. Participants may receive up to 3 dose level escalations of ST-04 over a 12-week period, for a total of up to 11 administrations of ST-04. Dose escalation may also be done with and without sildenafil.

A Survey of Traditional Medicine Pattern Identification in Patients With Erectile Dysfunction

Erectile dysfunction (ED) is a common condition that significantly affects quality of life, psychological well-being, and interpersonal relationships. In Traditional Medicine, ED is classified into different syndrome patterns, which are essential for guiding individualized treatment; however, evidence on their distribution and associated factors in Vietnam remains limited. This cross-sectional study aims to determine the distribution of Traditional Medicine syndrome patterns in patients with ED and to evaluate their associations with demographic characteristics, clinical features, psychological status, and lifestyle factors, thereby providing evidence to support improved diagnosis and integrative treatment approaches.

Daily Tadalafil 5 mg Combined With On-Demand Sildenafil 100 mg for Treatment of Erectile Dysfunction in PDE-5I Non Responder Patients

The goal of this clinical trial is to evaluate whether daily dosing with tadalafil 5 mg combined with on-demand sildenafil 100 mg can improve erectile function in men with erectile dysfunction (ED) who do not respond to PDE5 inhibitor alone. The main questions it aims to answer are: * Does the combination of daily tadalafil and on-demand sildenafil lead to a greater improvement in erectile function (measured by the IIEF-EF domain) compared with on-demand sildenafil alone? * Is the combination therapy safe and well tolerated in this patient population? Researchers will compare: * Group A: Daily tadalafil 5 mg plus on-demand sildenafil 100 mg * Group B: Daily placebo plus on-demand sildenafil 100 mg to determine whether the combination regimen provides superior improvement in erectile function and patient satisfaction. Participants will: * Undergo baseline assessment including medical history, physical examination, and laboratory tests. * Be randomly assigned to one of the two treatment groups. * Take the assigned medications for 12 weeks. * Complete follow-up evaluations at 4, 8, and 12 weeks, including: International Index of Erectile Function (IIEF-15) questionnaire Erection Hardness Score (EHS) assessment Reporting of any adverse effects

Acupuncture for Erectile Dysfunction

Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a prevalent chronic urological disease. CP/CPPS severely impacts patients' quality of life. It is characterized by recurrent pelvic floor pain, lower urinary tract symptoms, and often accompanied by psychological issues and sexual dysfunction (duration ≥3 months, no confirmed infection/pathology). The investigators have completed a large-sample, multi-center randomized controlled trial (RCT) involving 440 patients with CP/CPPS before. The clinical trial confirmed the sustained efficacy of acupuncture for the symptoms of pain, lower urinary tract symptoms, and anxiety and depression among patients with CP/CPPS. However, the trial revealed no significant improvements in sexual dysfunction in the acupuncture group compared to the sham acupuncture group after 8 weeks of treatment.To address this limitation, the current study is designed, which aims to optimize the clinical acupuncture protocol for CP/CPPS and evaluate whether it can enhance outcomes for psychogenic erectile dysfunction (ED) associated. Additionally, mass cytometry and liquid suspension chip technology will be used to explore systemic and local immune mechanisms underlying acupuncture's effects for CP/CPPS. Functional magnetic resonance imaging (fMRI) and metabolomics will be integrated to analyze patients' systemic states from central nervous system and metabolic perspectives, comprehensively elucidating the multi-dimensional mechanisms by which acupuncture alleviates CP/CPPS.

A Potential Relationship Between Treatment With Tyrosine Kinase Inhibitors and Erectile Dysfunction in Male Patients With Chronic Myeloid Leukemia

Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm characterized by the presence of the Philadelphia chromosome, resulting in the constitutive activation of the BCR-ABL1 tyrosine kinase. The advent of tyrosine kinase inhibitors (TKIs) has revolutionized the management of CML, trasforming it from a fatal disease to a chronic condition with excellent long-term outcomes for the majority of patients. The introduction of tyrosine kinase inhibitor (TKI) based treatment for CML has revolutionized the management of this previously fatal disease, achieving sustained disease-control in more than 90% of patients. However, as patients with CML are often required to undergo lifelong TKI therapy to maintain disease control, concerns regarding the long-term safety and tolerability of these agents have emerged. The efficacy of second and third-generation TKIs exceeds the efficacy of imatinib, owing to their potent impact on wild-type BCR-ABL1 and various BCR-ABL1 mutants, along with additional drug targets. Furthermore, TKIs exhibit activity on non-kinase targets (es. oxidoreductase NQO2 for nilotinib and imatinib). The prolonged treatment duration and expanded TKIs repertoire have led the emergence of various unexpected non-hematologic adverse events (AE), notably vascular adverse events (VAEs). Recent evidence indicates a relatively high incidence of severe arterial changes in TKI-treated patients, with VAEs frequency correlating with TKI dosage and treatment duration. However, data elucidating the clinical features of vascular events are lacking. Hormonal alterations have been reported in patients treated with imatinib. The tyrosine-kinase receptors cKIT and PDGF receptors, along with their respective ligands, are expressed in the testis, where they play a role in stimulating testosterone secretion by Leydig cells. Prolonged imatinib use has been associated with reduced testosterone production due to PDGFR and cKit blockade in the testis, potentially leading to gynaecomastia in men. Cardiovascular disease (CVD) remains the leading cause of mortality in the United States, accounting for nearly 40% of all deaths. CVD and ED share a variety of common risk factors, including hypertension, diabetes, dyslipidemia, smoking, obesity, physical inactivity, and metabolic syndrome. Screening and diagnosing ED hold significant potential for secondary prevention of CVD. Despite the estabilished association between ED and CVD, the precise mechanisms driving ED's predictive value for CVD are yet to be fully identified. Early deection and treatment of CVD during the critical time frame in which risk factors can be modified will effectively reduce the occurrence of fatal CV events in male patients with ED. This is a multicentre national, retrospective, prospective, non-interventional study that focuses on male CML patients starting first-line treatment with TKIs between 1 January 2015 and 31 January 2022. All enrolled patients will be involved in both retrospective and prospective evaluations. The retrospective component of the study allows the collection of data on the onset of ED, documented in medical records, that occurred before enrolment. It also includes information from physical examinations and laboratory tests, such as complete blood count, serum biochemistry (including renal and liver function tests, lipid profile and glycosylated haemoglobin), molecular biology for BCR-ABL transcript levels and electrocardiography (ECG), collected retrospectively every six months from enrolment until the documented onset of ED. The prospective evaluation assesses the occurrence of ED in the six months prior to enrolment and during the two-year follow-up period. The primary objective of the study is to assess the incidence of erectile dysfunction (ED) among male patients with chronic myeloid leukaemia (CML) undergoing treatment with tyrosine kinase inhibitors (TKIs), imatinib, dasatinib, nilotinib, bosutinib or ponatinib, focusing in particular on those individuals who report the appearance of associated symptoms after treatment.
