RESUMO

AIM: To evaluate the efficacy and safety of an oral, once-daily, 14-day treatment course of zuranolone in Japanese patients with major depressive disorder (MDD). METHODS: This multicenter, randomized, double-blind, placebo-controlled study randomized eligible patients (1:1:1) to receive oral zuranolone 20 mg, zuranolone 30 mg, or placebo once daily for 14 days (treatment-period), followed by two 6-week follow-up periods. The primary endpoint was change from baseline in the 17-item Hamilton Depression Rating Scale (HAMD-17) total score on Day 15. RESULTS: Overall, 250 patients (enrolled: 07/07/2020-05/26/2021) were randomized to receive placebo (n = 83), zuranolone 20 mg (n = 85), or zuranolone 30 mg (n = 82). The demographic and baseline characteristics were balanced between groups. The adjusted mean (standard error) change from baseline in the HAMD-17 total score on Day 15 was -6.22 (0.62), -8.14 (0.62), and - 8.31 (0.63) in the placebo, zuranolone 20-mg, and zuranolone 30-mg groups, respectively. Significant differences in the adjusted mean (95% confidence interval [CI]) for zuranolone 20 mg versus placebo (-1.92; [-3.65, -0.19]; P = 0.0296) and zuranolone 30 mg versus placebo (-2.09; [-3.83, -0.35]; P = 0.0190) groups were observed on Day 15, and also as early as Day 3. A nonsignificant yet distinct drug-placebo separation was observed during follow-up. Somnolence (placebo [3.7%], zuranolone 20 mg [10.6%], and zuranolone 30 mg [20.7%]) and dizziness (3.7%, 9.4%, and 9.8%, respectively) were more common with zuranolone. CONCLUSION: Oral zuranolone was safe and demonstrated significant improvements in depressive symptoms, as assessed by HAMD-17 total score change from baseline over 14 days in Japanese patients with MDD.

RESUMO

Thrombocytopenia may be associated with increased bleeding risk impacting timing and outcome of invasive procedures in patients with chronic liver disease (CLD). Lusutrombopag, a small-molecule, thrombopoietin (TPO) receptor agonist, was evaluated as a treatment to raise platelet counts (PCs) in patients with thrombocytopenia and CLD undergoing invasive procedures. L-PLUS 2 was a global, phase 3, randomized, double-blind, placebo-controlled study. Adults with CLD and baseline PCs < 50 × 109 /L were randomized to receive once-daily lusutrombopag 3 mg or placebo ≤ 7 days before an invasive procedure scheduled 2-7 days after the last dose. The primary endpoint was avoidance of preprocedure platelet transfusion and avoidance of rescue therapy for bleeding. A key secondary endpoint was number of days PCs were ≥ 50 × 109 /L throughout the study. Safety analysis was performed on patients who received at least one dose of study drug. This study occurred between June 15, 2015, and April 19, 2017, with a total of 215 randomized patients (lusutrombopag, 108; placebo, 107); 64.8% (70/108) of patients in the lusutrombopag group versus 29.0% (31/107) in the placebo group met the primary endpoint (P < 0.0001; difference of proportion 95% confidence interval [CI], 36.7 [24.9, 48.5]). The median duration of PCs ≥ 50 × 109 /L was 19.2 days with lusutrombopag (without platelet transfusion) compared with 0.0 in the placebo group (with platelet transfusion) (P = 0.0001). Most adverse events were mild or moderate in severity, and rates were similar in the lusutrombopag and placebo groups (47.7% and 48.6%, respectively). Conclusion: Lusutrombopag was superior to placebo for reducing the need for platelet transfusions and achieved durable PC response in patients with thrombocytopenia and CLD undergoing invasive procedures, with a safety profile similar to placebo.

RESUMO

AIM: This phase 1 study assessed the pharmacokinetics, safety, and tolerability of zuranolone in Japanese and White healthy adults, and Japanese healthy elderly subjects. METHODS: This single-center study consisted of three parts. In Part A (randomized, double-blind), the safety, tolerability, and pharmacokinetics of single dose and 7-day consecutive multiple doses of zuranolone 10, 20, and 30 mg and placebo were assessed in 36 Japanese adults, 24 White adults, and 12 Japanese elderly (aged 65-75 years) subjects. In Part B (randomized, open-label, crossover), the effect of food intake on the pharmacokinetics and safety of single-dose zuranolone 30 mg was evaluated in 12 Japanese adults. In Part C (randomized, double-blind, crossover), the effects of single-dose zuranolone 10 and 30 mg and placebo on electroencephalography parameters were evaluated in eight Japanese adults. RESULTS: Single and multiple doses of zuranolone were safe and well tolerated in all subjects. Linear pharmacokinetics were observed in the studied dose range. Time to steady-state plasma concentration was within 72 h for Japanese and White adults. Pharmacokinetic profiles were comparable between Japanese and White adults and between Japanese adults and Japanese elderly subjects. Plasma exposures of zuranolone were greater in the fed versus fasted state. Single-dose zuranolone 30 mg increased low-beta electroencephalography power. CONCLUSION: In healthy Japanese subjects, zuranolone was well tolerated; pharmacokinetic profile was unaffected by ethnicity or age; plasma exposures were greater in the fed state. The increased low-beta electroencephalography power with the 30-mg dose is consistent with γ-aminobutyric acid receptor type A activation by zuranolone.

RESUMO

An ethanol extract of Helichrysum maracandicum showed antiproliferative activity against cultured cells of SENCAR mouse in an in vitro assay, and activity-guided fractionation of the extract resulted in the isolation of isosalipurposide as an active substance. Naringenin chalcone, the aglycone of isosalipurposide, also showed strong antiproliferative activity. An in vivo assay of two-stage carcinogenesis on mouse skin revealed that epidermal application of isosalipurposide resulted in delayed formation of papillomas. Western blot analysis showed that the expression of p38 mitogen-activated protein kinase was suppressed by the administration of naringenin chalcone or isosalipurposide, which might be related to the anticarcinogenic activity.
