Objective:To evaluate the interaction between remimazolam and propofol for sedation during hysteroscopy.Methods:American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 20-45 yr, with body mass index of 18-28 kg/m 2, scheduled for elective hysteroscopy, were included. The test was conducted in two steps. Up-and-down sequential allocation was used to determine the median effective dose (ED 50) of remimazolam (group A) and propofol (group B). The ED 50 obtained in A and B groups were then used as the standard to determine the combination regimen in group C (0.25×ED 50 of remimazolam+ 0.75×ED 50 of propofol as the initial dose), in group D (0.5×ED 50 of remimazolam+ 0.5×ED 50 of propofol as the initial dose), and in group E (0.75×ED 50 of remimazolam+ 0.25×ED 50 of propofol as the initial dose). Up-and-down sequential allocation was used to determine the ED 50 of propofol when propofol and remimazolam were combined in C, D and E groups. The interaction between the sedative effects of two drugs was analyzed using the isobolographic analysis method, and the interaction coefficient and synergistic dose ratio of two drugs were calculated. Results:The ED 50 of remimazolam was 0.180 mg/kg in group A, and the ED 50 of propofol was 1.167 mg/kg in group B. The results of isobolographic analysis showed that remimazolam and propofol had a synergistic effect. When remimazolam 0.045, 0.090 and 0.135 mg/kg were combined with propofol 0.546, 0.288 and 0.160 mg/kg, the interaction coefficients were 1.393, 1.339 and 1.127 respectively. The synergistic dosage ratio of remimazolam and propofol was 1.0∶(3.2 to 12.0). Conclusions:Remimazolam and propofol have a synergistic effect on sedation when used for hysteroscopy, and the dose ratio is 1.0∶(3.2-12.0).

Background::Atopic dermatitis (AD) affects approximately 10% of adults worldwide. CM310 is a humanized monoclonal antibody targeting interleukin-4 receptor alpha that blocks interleukin-4 and interleukin-13 signaling. This trial aimed to evaluate the efficacy and safety of CM310 in Chinese adults with moderate-to-severe AD.Methods::This multicenter, randomized, double-blind, placebo-controlled, phase 2b trial was conducted in 21 medical institutions in China from February to November 2021. Totally 120 eligible patients were enrolled and randomized (1:1:1) to receive subcutaneous injections of 300 mg CM310, 150 mg CM310, or placebo every 2 weeks for 16 weeks, followed by an 8-week follow-up period. The primary endpoint was the proportion of patients achieving ≥75% improvement in the Eczema Area and Severity Index (EASI-75) score from baseline at week 16. Safety and pharmacodynamics were also studied.Results::At week 16, the proportion of EASI-75 responders from baseline was significantly higher in the CM310 groups (70% [28/40] for high-dose and 65% [26/40] for low-dose) than that in the placebo group (20%[8/40]). The differences in EASI-75 response rate were 50% (high vs. placebo, 95% CI 31%–69%) and 45% (low vs. placebo, 95% CI 26%–64%), with both P values <0.0001. CM310 at both doses also significantly improved the EASI score, Investigator’s Global Assessment score, daily peak pruritus Numerical Rating Scale, AD-affected body surface area, and Dermatology Life Quality Index compared with placebo. CM310 treatment reduced levels of thymus and activation-regulated chemokine, total immunoglobulin E, lactate dehydrogenase, and blood eosinophils. The incidence of treatment-emergent adverse events (TEAEs) was similar among all three groups, with the most common TEAEs reported being upper respiratory tract infection, atopic dermatitis, hyperlipidemia, and hyperuricemia. No severe adverse events were deemed to be attributed to CM310. Conclusion::CM310 at 150 mg and 300 mg every 2 weeks demonstrated significant efficacy and was well-tolerated in adults with moderate-to-severe AD.Trial Registration::ClinicalTrials.gov, NCT04805411.
