Background:

In the FUEL (Fontan Udenafil Exercise Longitudinal) trial, a positive treatment effect was identified for outcomes at the ventilatory anaerobic threshold but not for the primary outcome, oxygen consumption (V o2 ) at peak exercise. This disparate response may be explained by the physiologic challenge of improving peak V o2 in participants with near‐normal baseline exercise performance.

Methods:

Participants were divided into subgroups by baseline predicted peak V o2 (<80% versus ≥80%). Treatment effect was evaluated in those with a baseline peak V o2 <80% predicted and linear regression was performed to examine the interaction between subgroup and response to therapy for the primary and secondary outcomes.

Results:

Of the 379 participants with paired exercise data, 302 (80%) had a baseline peak V o2 <80% predicted. In this subgroup, the primary outcome of peak V o2 improved significantly after 6 months of udenafil treatment, when compared with placebo (0.23±4.17 mL/kg per min versus −0.90±3.74 mL/kg per min; P =0.021). Secondary outcome measures, including V o2 at ventilatory anaerobic threshold ( P =0.023), work at ventilatory anaerobic threshold ( P =0.032), and the myocardial performance index ( P =0.007) were all significantly improved as well. A significant interaction was found between exercise subgroups and response to udenafil for peak V o2 ( P =0.036) but not for other outcomes.

Conclusions:

In this post hoc subgroup analysis, after exclusion of patients with Fontan circulation with near‐normal baseline peak V o2 , a positive treatment effect of udenafil was identified for the primary outcome of peak V o2 . The interaction between baseline peak V o2 and treatment may have influenced the outcome of the FUEL trial.

Identification of Phosphodiesterase type 5 inhibitors (PDE5is) analogues using surface-enhanced Raman scattering and machine learning algorithm

Article

Author: Huang, Jiadong ; He, Hongyuan ; Li, Yujing ; Luan, Yujing

Phosphodiesterase type 5 inhibitors (PDE5is), primarily used for the treatment of erectile dysfunction, have been severely misused in recent years, posing a threat to public health and safety. This study developed a method that combines Surface-enhanced Raman spectroscopy (SERS) with machine learning algorithms to rapidly identify different PDE5is types. A total of 948 SERS spectra from 79 PDE5is were collected using gold nanoparticles (AuNPs) as the enhancement agent, and dimensionality reduction was performed through principal component analysis (PCA). Subsequently, six traditional machine learning models, partial least squares discriminant analysis (PLS-DA), orthogonal partial least squares discriminant analysis (OPLS-DA), support vector machines (SVM), k-nearest neighbors (KNN), random forest (RF), and multilayer perceptron (MLP) were applied for data classification and identification. Results showed that the MLP model achieved the highest classification accuracy of 99.65 %, with only 1.82 % of the samples misclassified from thiosildenafil to sildenafil analogues, significantly outperforming the other models. This method offers a rapid, cost-effective, and accurate alternative for the detection of PDE5is in health foods, with implications for improving regulatory oversight and public health safety.

Postmicturition dribble in men with no previous urogenital surgery: Systematic review and meta‐analysis of treatment modalities

Review

Author: Mahdi, Mohammed ; Lock, Merilyn ; El Ansari, Walid ; Hothi, Hanaa Al ; Arafa, Mohamed ; Ghafouri, Ardalan ; Megahed, Heba ; Albakr, Ahmed

Abstract:

Introduction:

Postmicturition dribble (PMD) is common in males. Little is known about PMD etiology, but it is either secondary to urethral/prostatic surgery or primary (no previous surgery). Despite PMD's high prevalence, the effectiveness of its treatment modalities remains lacking.

Objective:

To undertake a systematic review of the available treatments for primary PMD in adult males and meta‐analysis of their effectiveness.

Materials and Methods:

We searched four electronic databases from inception to 2023 for original articles that evaluated PMD treatments in male adults without previous urethral/prostatic surgery (PROSPERO protocol CRD42023444591). Study quality and risk of bias were evaluated using established tools. We extracted a range of variables including treatment modality used and its effectiveness on PMD volume and patient complaint. Meta‐analysis was undertaken where feasible, and where this was not feasible, narrative synthesis was conducted.

Results:

Out of 335 studies, four were included (four clinical trials, n = 344 patients). Two trials used physical/behavioral therapy (pelvic floor muscle exercises [PFMEs], urethral milking); the other two employed phosphodiesterase (PDE5) inhibitors (tadalafil, Udenafil). All studies were of good quality, but physical/behavioral therapy studies had some risk of bias. As the two physical/behavioral therapy studies used heterogenous outcome measures, narrative synthesis showed PMD volume improvement with PFMEs more than with urethral milking, both modalities were more effective than counseling, and in one study, PFMEs were effective in reducing PMD self‐reported complaint than counseling. Meta‐analyses of the two PDE5 inhibitors studies showed a large effect size with high heterogeneity for decreased PMD volume favoring PDE5 inhibitors over placebo (g = −0.86, 95% confidence interval [CI] −1.75; 0.02, p = 0.05; I2 = 88%); and a significant improvement equivalent to −1.06 points on the Hallym PMD Questionnaire score with no discernable heterogeneity (95% CI −1.65; −0.47, p = 0.0004; I2 = 0%), favoring PDE5 inhibitors compared to controls.

Conclusions:

Physical/behavioral therapy and PDE5 inhibitors are effective primary PMD treatments. PMD management studies in males with no previous urethral/prostatic surgery are very scarce and lack the use of consistent/comparable outcome measures. Further studies addressing these deficiencies would benefit this very thin evidence base.

Post-Hoc FUEL Trial Analysis Shows Udenafil Significantly Improves Exercise Capacity in Fontan Patients with Reduced Baseline Function

SEOUL, South Korea, Aug. 12, 2025 /PRNewswire/ -- A newly published post-hoc analysis of the landmark FUEL (Fontan Udenafil Exercise Longitudinal) Trial demonstrates that udenafil, a PDE5 inhibitor, significantly improves peak oxygen consumption (peak VO₂) in adolescents with single ventricle congenital heart disease (SV-CHD) who have undergone the Fontan procedure and have reduced exercise capacity. Published in the Journal of the American Heart Association: "Revisiting the Effect of Udenafil on Exercise Performance in Patients With Fontan Circulation: Results of a Post Hoc Analysis of the FUEL Trial" The original multinational, randomized, placebo-controlled Phase 3 FUEL trial demonstrated statistically significant improvements in key secondary endpoints – such as VO₂ at ventilatory anaerobic threshold (VAT) and myocardial performance index (MPI) – but narrowly missed statistical significance for the primary endpoint of peak VO₂ in the overall population. Recognition of a high performing "Super Fontan" subgroup prompted further analysis stratifying participants by baseline peak VO₂ (<80% vs. ≥80% of predicted) to assess whether initial exercise capacity influenced treatment response. Key findings from the post-hoc analysis: In the 302 patients with baseline peak VO₂ <80% predicted (80% of the evaluable cohort), udenafil significantly improved peak VO₂ compared to placebo (p=0.021). Significant improvements were also observed in VO₂ at VAT (p=0.023), work at VAT (p=0.032), and MPI (p=0.007). A significant interaction between baseline exercise capacity and treatment effect for peak VO₂ (p=0.036) suggests that including high-functioning patients, whose physiologic ceiling may limit measurable gains, could have masked the full treatment effect in the original trial. "These results provide a possible physiologic explanation for the outcomes of the FUEL trial and support further investigation of udenafil in Fontan patients with reduced exercise capacity," said Dr. David Goldberg, lead author and pediatric cardiologist at Children's Hospital of Philadelphia. "This analysis highlights the need for a confirmatory clinical trial targeted to the large majority of Fontan patients who are most likely to demonstrate benefit using peak VO2 as the primary endpoint." "Importantly, the absence of a detectable change in peak VO₂ among higher-functioning Fontan patients may reflect– what may be termed a 'ceiling effect' – rather than a lack of therapeutic response," added Dr. Bryan H. Goldstein, senior author and Director of the Cardiac Catheterization Laboratory at UPMC Children's Hospital of Pittsburgh. "These patients still achieve meaningful improvements in submaximal exercise measures such as VO₂ at VAT and MPI. Moreover, as these younger, high-performing individuals age and are further exposed to ongoing Fontan circulatory stresses, their exercise capacity with decline and therefore, the need for targeted pharmacotherapy will likely increase." The findings highlight the importance of selecting appropriate endpoints and stratifying populations in rare disease trials. Informed by FUEL, the ongoing confirmatory phase 3 FUEL-2 trial focuses on Fontan patients with reduced baseline exercise capacity – those in whom changes in peak VO₂ are most reliably measurable. "This focused design increases the likelihood of demonstrating efficacy on the primary endpoint, while still capturing udenafil's broader therapeutic potential," said Dr. Rahul Rathod, Global Principal Investigator for FUEL-2 and Director of the Single Ventricle Program at Boston Children's Hospital. "Given the strong link between peak VO₂ and long-term outcomes in Fontan patients, a +1.13 mL/kg/min improvement over six months is clinically meaningful and may influence disease progression." The FUEL trial was supported by the National Heart, Lung, and Blood Institute (NHLBI) and Mezzion Pharma Co., Ltd., the regulatory sponsor of udenafil development for Fontan patients.

Mezzion Pharmaceuticals Reaches Key Enrollment Milestone in World's Largest Fontan Clinical Trial

SEOUL, South Korea, July 31, 2025 /PRNewswire/ -- Mezzion Pharmaceuticals, Inc. (Mezzion) announced that its confirmatory Phase 3 FUEL-2 study evaluating JURVIGO® (udenafil)1 in adolescents and young adults with Fontan circulation has surpassed a key enrollment milestone randomizing approximately 50% of the planned 400+ participants. Continue Reading “FUEL-2 is aiming to bring hope to a resilient and underserved community.” FUEL-2 is the largest randomized clinical trial ever conducted for the Fontan population, a group of patients born with single ventricle congenital heart disease who require a series of surgeries culminating in the Fontan procedure. This population remains at high risk for heart failure, organ dysfunction, and early mortality, with no FDA-approved pharmacologic therapies available today. "The Fontan journey is long, complex, and often isolating," said Dr. Rahul Rathod, Global Principal Investigator for FUEL-2 and Director of the Single Ventricle Program at Boston Children's Hospital. "With FUEL-2, we're doing more than just advancing a treatment – we're building hope, community, and scientific clarity around a disease that has gone too long without answers." Udenafil, a highly selective and long-acting PDE5 inhibitor, has demonstrated its clinical benefit in Fontan patients with reduced functional capacity (peak VO₂ < 80% of predicted). In the original FUEL trial, this subgroup experienced the most pronounced improvements, particularly in submaximal exercise measures such as ventilatory efficiency and anaerobic threshold – indicators closely tied to functional status in daily life. These findings, combined with FDA-aligned guidance and a growing body of published evidence, informed the focused enrollment criteria for FUEL-2, which is evaluating udenafil exclusively in this higher-risk population. Udenafil has been shown to be safe and well tolerated across more than five years of cumulative exposure, including long-term use in a diverse group of adolescents and young adults from the FUEL trial's open-label extension. In FUEL-2, the primary efficacy endpoint is the change in peak VO2 (mL/kg/min) following 26 weeks of treatment. Peak VO₂ is a validated surrogate for major clinical outcomes, including hospitalization, transplant, and mortality, and a 10% decline is associated with nearly double the risk of death or transplant in Fontan patients.2"We believe every child and young adult living with Fontan circulation deserves a future with better options," said Dong Hyun 'Dean' Park, Chairman and CEO of Mezzion. "FUEL-2 reflects our deep commitment not only to science but also to the families, clinicians, and advocates who have helped bring this vision to life." To ensure the highest data quality, all cardiopulmonary exercise testing (CPET) in FUEL-2 is centrally reviewed by The Lundquist Institute, an internationally recognized leader in cardiopulmonary diagnostics. This centralized approach enhances consistency and precision in measuring both primary and secondary endpoints across all global sites. FUEL-2 is being conducted at more than 30 of the world's leading children's hospitals across the United States and South Korea. The trial is supported by a global coalition of patient advocacy organizations, clinical investigators, and families dedicated to improving long-term outcomes for individuals with Fontan circulation. Join the Movement Patients and families interested in learning more or joining the study can visit or speak with their care team at a participating center. Clinical sites and investigators are encouraged to continue building on this momentum as we enter the second half of enrollment.
