Background: Clinical trials of treatments for coronavirus disease 2019 (Covid-19) have not shown a significant benefit of postexposure prophylaxis.
Methods: We conducted a phase 2-3 double-blind trial to assess the efficacy and safety of nirmatrelvir-ritonavir in asymptomatic, rapid antigen test-negative adults who had been exposed to a household contact with Covid-19 within 96 hours before randomization. The participants were randomly assigned in a 1:1:1 ratio to receive nirmatrelvir-ritonavir (300 mg of nirmatrelvir and 100 mg of ritonavir) every 12 hours for 5 days or for 10 days or matching placebo for 5 or 10 days.
Background/objective: The objective of this study was to investigate the safety and efficacy of subcutaneous (SC) and intravenous (IV) tanezumab administration in osteoarthritis (OA) patients.
Materials And Methods: Study 1027 (NCT01089725), a placebo-controlled trial, evaluated the efficacy of SC tanezumab (ie, 2.5, 5, and 10 mg) and the therapeutic equivalence of 10 mg tanezumab given subcutaneously versus intravenously every 8 weeks in the symptomatic treatment of OA.
Objective: To evaluate peripheral nerve safety and clinical efficacy of tanezumab in patients with painful osteoarthritis.
Methods: Patients received intravenous tanezumab 5mg, tanezumab 10mg, or placebo every 8 weeks for 24 weeks. Neurological safety was evaluated via a composite score (nerve conduction attributes and heart rate variability with deep breathing; Σ5NC + HRdb), intraepidermal nerve fiber (IENF) density, and clinical assessments.
