This prospective multicentre, double-blind, randomized, parallel-group, placebo-controlled trial evaluated the efficacy and safety of a single dose of eletriptan 20 mg, 40 mg and 80 mg in Japanese migraineurs. A total of 402 adult Japanese migraineurs were diagnosed using International Headache Society (IHS) criteria. At 2 h after a single dose, the headache response rates of eletriptan 20 mg, 40 mg, 80 mg and placebo were 64%, 67%, 76% and 51%, respectively, with all doses significantly superior to placebo ( P< 0.05). Eletriptan had a statistically significant dose response for headache relief and pain-free response at 2 h post-dose ( P = 0.0011 and P = 0.0291, respectively). Most all-causality adverse events were mild and there were no deaths or discontinuations. Saliva samples were used to assess serum eletriptan levels 2 h post-dose. Pharmaco-kinetic evaluations showed no clinically significant differences between Japanese and Western subjects. Eletriptan was shown to be efficacious, safe, and well tolerated in Japanese migraineurs.

Abstract Background Acute pharyngitis and tonsillitis are common respiratory diseases for which children seek medical care. Their main clinical manifestation is sore throat which interferes with patients’ quality of life. However, there is no proven effective or safe method to treat it. It is necessary to find an excellent strategy to reduce sore throat and reduce the burden of acute illness. We designed the randomized controlled trial with the characteristics of traditional Chinese medicine (TCM) to determine the clinical positioning of Kai-Hou-Jian spray (children’s type) (KHJS) through evidence-based research. This trial aims to evaluate the immediate analgesic efficacy of KHJS on sore throat caused by acute pharyngitis and tonsillitis (wind-heat syndrome/heat exuberance in lung and stomach syndrome) in children and to observe its safety. Methods/design This is a prospective, multicenter, randomized, double-blind, parallel-group, placebo-controlled trial. It will include 240 children with acute pharyngitis/tonsillitis from 7 study sites across China. All participants are randomly assigned to two parallel treatment groups, one with KHJS and the other with placebo sprays, for 5 consecutive days. The primary outcome is the time of analgesic onset. Secondary outcomes include duration of analgesic effect, area under time curve of 0–3 h Wong-Baker FACES Pain Rating Scale (WBS) score (AUC0-3 h), rate of analgesic onset, rate of disappearance of sore throat, changes of WBS score (in days), effective rate of pharyngeal signs, and effective rate of TCM syndrome. The incidence of adverse events during the trial is the primary safety outcome. In addition, vital signs and laboratory tests before and after medication are monitored. Discussion To our knowledge, this will be the first clinical trial to explore the immediate analgesic efficacy of a Chinese patent medicine spray for acute pharyngitis/tonsillitis induced sore throat in children in a multicenter, randomized, double-blinded, parallel-group, placebo-controlled manner. Not only might it prove the efficacy and safety of KHJS in the treatment of sore throat caused by acute pharyngitis/tonsillitis in children, but it might also provide evidence for the treatment of acute sore throat with Chinese herbal medicine. Trial registration A multicenter, randomized, double-blind, very low-dose, parallel controlled trial for the immediate analgesic effect and safety of Kai-Hou- Jian spray (children's type) in the treatment of sore throat caused by acute pharyngitis and tonsillitis in children.

To determine the tolerability and efficacy of eletriptan in patients who had discontinued oral sumatriptan due to lack of efficacy or intolerable adverse events (AEs) during previous clinical treatment (not a controlled trial). Eletriptan is a potent, selective 5-HT1B/1D receptor agonist with beneficial pharmacokinetic properties compared with sumatriptan. In a double-blind, parallel group, placebo-controlled multicentre study, patients with and without aura ( n = 446) were randomized to 40 mg eletriptan (E40, n = 188), 80 mg eletriptan (E80, n = 171) or placebo ( n = 87) for treatment of up to three migraine attacks. Two-hour headache response, based on first-dose, first-attack data, was 59% for eletriptan 40 mg, 70% for eletriptan 80 mg, and 30% for placebo ( P < 0.0001 for both doses of eletriptan vs. PBO; P < 0.05 for E80 vs. E40). Onset of action was rapid, with 1-h headache response rates significantly superior for E40 and E80 vs. placebo (40%, 48%, 15%; P < 0.0005). Both E40 and E80 were significantly superior to placebo, based on first-dose, first-attack data, for 2-h pain-free response (35%, 42%, and 7%; P < 0.0001). Both E40 and E80 demonstrated significant consistency of response, with headache relief rates at 2 h on at least two of three attacks in 66% and 72% vs. 15% on placebo ( P < 0.001). AEs were mild to moderate in severity and dose related. The most commonly reported AEs included nausea, vomiting, asthenia, and chest symptoms. E40 and E80 produce an effective response in patients who had previously discontinued treatment with sumatriptan due to lack of efficacy or side-effects.

Abstract Purpose MB02 is a biosimilar to bevacizumab that has demonstrated similar physicochemical and functional properties in in vitro studies to the reference bevacizumab (Avastin®). This study aims to assess the pharmacokinetic (PK) similarity of MB02 to the reference bevacizumab in Japanese population. Methods This double-blind, randomized, parallel-group, single-dose PK study, was performed in healthy Japanese male volunteers. Subjects were equally randomized (1:1) to receive a single (3 mg/kg) IV dose of MB02 or reference bevacizumab. PK assessments were done up to 70 days post-dose. Non-compartmental parameters were calculated. PK similarity was determined using predefined equivalence range (0.80–1.25) for the area under the serum concentration–time curve from time 0 extrapolated to infinity (AUC0–∞). Immunogenicity samples were taken pre-dose and up to day 70. Safety was assessed throughout the study. Results In total, 48 subjects (24 in each treatment group) were dosed. Consequently to the observed similar PK profile, the 90% confidence interval for the geometric means ratio for the primary PK endpoint, AUC0–∞, was within the predefined equivalence range (0.981–1.11). Forty-seven treatment-emergent adverse events (TEAEs) were reported in 20 subjects (41.7%) with comparable incidence among MB02 and reference bevacizumab groups (22 and 25, respectively), none of them was severe or serious. Anti-drug antibodies incidence was low and similar between treatment groups. Conclusions Pharmacokinetic similarity of MB02 to reference bevacizumab was evidenced in Japanese healthy subjects, with comparable safety and immunogenicity profile between treatments. This study supports the biosimilarity of MB02 to reference bevacizumab in Japanese population. ClinicalTrials.gov identifier: NCT04238650.

Meta Analyses

This was a randomized, double-blind study designed to evaluate the comparative efficacy and tolerability of the 40-mg dose of eletriptan and the 2.5-mg dose of naratriptan. Patients ( n = 548) meeting International Headache Society (IHS) criteria for migraine were randomized to treat a single migraine attack with either eletriptan 40 mg, naratriptan 2.5 mg, or placebo. Headache response rates at 2 h and 4 h, respectively, were 56% and 80% for eletriptan, 42% and 67% for naratriptan ( P < 0.01 for both time-points vs. eletriptan), and 31% and 44% for placebo ( P < 0.0001 vs. both active drugs at both time-points). Eletriptan also showed a significantly greater pain-free response at 2 h (35% vs. 18%; P < 0.001) as well as lower use of rescue medication (15% vs. 27%; P < 0.01) and higher sustained headache response at 24 h (38%) compared with naratriptan (27%; P < 0.05) and placebo (19%; P < 0.01). Both eletriptan and naratriptan were well tolerated. The results confirm previous meta-analyses that have suggested the superiority of eletriptan vs. naratriptan in the acute treatment of migraine.
