RESUMEN

Importance: Developmental and epileptic encephalopathies (DEEs) are the most severe group of drug-resistant epilepsies. Alternatives to oral therapies are urgently needed to reduce seizures and improve developmental outcomes and comorbidities in this medically complex population. Objective: To assess the safety and tolerability of cannabidiol (CBD) transdermal gel in children with DEEs and to evaluate seizure frequency, sleep, and quality of life. Design, Setting, and Participants: This nonrandomized controlled trial was conducted in 2 centers in Australia and New Zealand from April 2018 to July 2019. Children and adolescents aged 3 to 18 years with DEEs who were receiving a stable regimen of 1 to 4 antiseizure medications were eligible for this study. After 1-month baseline and titration periods, patients entered a 5.5-month flexible-dosing maintenance period for a total of 6.5 months of treatment. Data were analyzed throughout the 6.5-month treatment period. Interventions: Twice-daily applications of CBD transdermal gel at doses of 125 to 500 mg for 6.5 months. Main Outcomes and Measures: Safety and tolerability assessments included adverse events (AEs) and examination of skin. The outcome for seizures was the median percentage change from baseline in monthly (28-day) seizure frequency of focal impaired awareness seizures (FIAS) and tonic-clonic seizures (TCS) over 6.5 months. Results: Of 48 patients (mean [SD] age, 10.5 [3.8] years; 26 [54%] boys), 29 (60%) had at least 1 treatment-related AE over 6.5 months; 44 of 46 treatment-related AEs (96%) were mild or moderate. Treatment-related AEs that occurred in at least 5% of patients were application-site dryness, application-site pain, and somnolence (each reported by 4 patients [8%]). The only treatment-related gastrointestinal AE was diarrhea, reported in a single patient. CBD treatment was associated with reductions in FIAS and TCS frequency. Analysis of the 33 patients with FIAS and TCS showed a median (interquartile range) monthly reduction in seizures of 58% (-5.3% to 81.8%) at 5 months and 43.5% (-23.8% to 57.5%) over the entire 6.5-month study period. Parents and caregivers noted improvements in social or interpersonal engagement and irritability (33 of 43 [77%] participants); alertness, energy, and sleep (23 of 43 [53%]); and cognition or concentration (20 of 43 [47%]). Conclusions and Relevance: In this study, CBD transdermal gel was safe, well tolerated, and was associated with reductions in FIAS and TCS frequency and disease burden. Trial Registration: ClinicalTrials.gov Identifier: ACTRN12618000516280.

RESUMEN

OBJECTIVE: Gastrointestinal symptoms, such as nausea and vomiting, occur almost universally at one time or another in patients during a migraine attack. One third of patients who experience migraine-related nausea report that this symptom interferes with their ability to take oral medications. The sumatriptan iontophoretic transdermal system (NuPathe Inc., Conshohocken, PA, USA) uses proprietary technology to circumvent the gastrointestinal tract while delivering triptan therapy. This phase III randomized, double-blind, placebo-controlled trial evaluated the efficacy and tolerability of this system for the acute treatment of migraine. METHODS: Patients were randomized to treat a single moderate-to-severe migraine attack with the sumatriptan iontophoretic transdermal system or placebo. The primary end point was the proportion of patients who were headache pain-free 2 hours after patch activation. Other end points included the proportions of patients who reported headache pain relief, and freedom from nausea, photophobia, and phonophobia; rescue medication use; and tolerability. RESULTS: Four hundred sixty-nine patients were treated. Significantly more patients treated with the sumatriptan iontophoretic transdermal system compared with placebo experienced freedom from headache pain, nausea, photophobia, and phonophobia 2 hours after patch activation, experienced rapid and sustained headache pain relief, and used less rescue medication. Treatment-emergent adverse events were reported by 50% and 44% of patients treated with the sumatriptan iontophoretic transdermal system and placebo, respectively. Most events were transient mild-to-moderate application-site reactions. CONCLUSIONS: The sumatriptan iontophoretic transdermal system is effective and well tolerated, and may be particularly useful in patients with migraine-related gastrointestinal symptoms such as nausea.

RESUMEN

Sexual activity, sexual desire, and mood decrease in men with low testosterone levels. The Testim(R) Study of Testosterone Androgen Response Time (START) explored the time to response in sexual activity, desire, and mood following testosterone replacement therapy with Testim for 30 days in 638 hypogonadal men. Response in sexual activity, desire, and mood all improved relative to baseline within the first week of Testim therapy. Patients reached a maximal response by the end of 2 weeks of therapy and maintained the response through 4 weeks of therapy. Frequency of intercourse showed a significant increase after 2 weeks of Testim therapy. Both measures of positive mood and negative mood improved significantly, beginning with the first week of therapy and reaching and maintaining a maximal response at the second week.
