RESUMO

Onychomycosis with longitudinal spikes in the nail plate has been reported to be refractory to oral drugs as with dermatophytoma. We evaluated the efficacy of 10% efinaconazole solution in the treatment of onychomycosis with longitudinal spikes. Of the 223 subjects who were enrolled in a previous study, a post-hoc analysis of 82 subjects with longitudinal spikes was performed in this study. The opacity ratio of longitudinal spikes was decreased over time from 8.1 to 0.9 at the final assessment. In addition, the longitudinal spike disappearance rate increased early after the application to 81.7% at the final assessment. Therefore, 10% efinaconazole solution can be a first-line drug for longitudinal spikes, which have been regarded as refractory to oral drugs.

RESUMO

A long-term study was conducted in Japanese patients with primary axillary hyperhidrosis who completed the preceding 6-week phase III, confirmatory study of 5% sofpironium bromide gel (hereinafter referred to as sofpironium) to evaluate the safety and efficacy of 52-week treatment with sofpironium. In the long-term study, 185 patients who completed the confirmatory study (94 and 91 patients in the vehicle and sofpironium groups, respectively) started to receive sofpironium (switching and extension groups, respectively), and all these patients were included in both the full analysis set (FAS) and the safety analysis set (SAF). In the FAS, there were more females than males (73.0% vs. 27.0%), and median age was 38.0 years. A total of 161 patients (86 and 75 patients in the switching and extension groups, respectively) completed the study at week 52. The proportions of patients with hyperhidrosis disease severity score of 1 or 2 and a 50% or more reduction in total gravimetric weight of sweat were 57.4% in the switching group and 58.2% in the extension group at week 52. The proportions of patients who achieved this efficacy end-point in the long-term study were similar to that (53.9%) in the sofpironium group in the confirmatory study. In the SAF, the incidences of adverse events (AEs) were 80.9% in the switching group and 83.5% in the extension group, and the incidences of adverse drug reactions were 39.4% and 45.1%, respectively. AEs that occurred in at least 20% of patients in both treatment groups were application site dermatitis (25.5% and 33.0%, respectively) and nasopharyngitis (31.9% and 23.1%, respectively). Reported AEs were generally mild, and there were no deaths. Serious AEs occurred in three patients, but none were considered related to the study drug. In this study, the efficacy of sofpironium was maintained during 52-week treatment, and no new safety risk was observed.

RESUMO

A phase 3 study was conducted to verify the efficacy and safety of 5% sofpironium bromide (BBI-4000) gel (hereinafter referred to as sofpironium) administrated for 6 weeks in Japanese patients with primary axillary hyperhidrosis. The primary efficacy end-point was the proportion of patients who satisfied both criteria of a Hyperhidrosis Disease Severity Score (HDSS) of 1 or 2 at the end of 6-week treatment and a 50% or more reduction in total gravimetric weight of sweat at the end of treatment relative to baseline. A total of 281 patients were randomized to receive 5% sofpironium (141 patients) or vehicle (140 patients), and all patients were included in the full analysis set (FAS). In the FAS, 70.1% of patients were female, and the median age was 35.0 years. The proportion of patients who achieved the primary efficacy end-point was 53.9% in the sofpironium group and 36.4% in the vehicle group, with a statistically significant difference of 17.5% (95% confidence interval, 6.02-28.93) between these two groups (P = 0.003). The incidence of adverse events was 44.0% in the sofpironium group and 30.7% in the vehicle group, and the incidence of adverse drug reactions was 16.3% in the sofpironium group and 5.0% in the vehicle group. Reported adverse events were generally mild or moderate in severity. In the sofpironium group, common events (incidence, ≥5%) were nasopharyngitis (14.2%) and dermatitis/erythema at the application site (8.5%/5.7%), with no serious adverse events reported. This study demonstrated the efficacy and safety of 5% sofpironium.

RESUMO

We evaluated the efficacy of efinaconazole 10% topical solution in long-term use, for up to 72 weeks, for onychomycosis, including severe cases. Among 605 participants, 219 patients diagnosed as having onychomycosis were evaluated for the efficacy of efinaconazole. The treatment success rate (<10% clinical involvement of the target toenail) at the final assessment time point was 56.6%, the complete cure rate was 31.1% and the mycological cure rate was 61.6%, all of which increased over time, demonstrating that continuous application contributed to the improvement of cure rate. Even in severe cases, reduction of the affected nail area was observed, showing the potential efficacy of the treatment. Responses to a quality of life questionnaire among patients with onychomycosis, OnyCOE-t, suggested that efinaconazole treatment improved the patients' quality of life. The incidence of adverse drug reaction in the patients eligible for the assessment was 6.3%, and this developed only in the administration site in all cases. No systemic adverse event was observed. In addition, no increase in the incidence of adverse drug reaction due to long-term use was found. Efinaconazole therapy was proved to exhibit excellent balance between efficacy and safety, and thus may serve as a useful treatment option for onychomycosis.

RESUMO

Antiphospholipid antibodies (aPL) have been reported to occur in several conditions other than antiphospholipid syndrome, including infections. We herein report the case of a 21-year-old Japanese woman with Parvovirus B19 infection, who developed multiple pulmonary emboli associated with aPL, a lupus anticoagulant and IgM anticardiolipin antibody. Eight weeks later, antiphospholipid antibodies spontaneously disappeared and normal pulmonary flow was observed. Considering the high prevalence of Parvovirus B19 infection, we should be aware of thrombosis associated with transient aPL antibodies in this infectious disease.
