چکیده

Background: Phase I study to assess the effects of single oral doses of 100, 200, and 300 mg/day of sodium tungstate (OXO-001) in healthy women of childbearing age.Materials and Methods: A randomized, double-blind, dose-finding, and placebo-controlled phase I study was con­ducted in healthy weight (body mass index [BMI] 18.5-24.9 kg/m2) and overweight (BMI 25 to ≥30 kg/m2) volunteers who received OXO-001 or placebo during a menstrual cycle (maximum 28 days). Data recorded were adverse events (AEs), vital signs, electrocardiogram (ECG), laboratory tests, pharmacokinetics (PK) parameters, and transvaginal ultrasound.Results: Thirty women were included in the safety analysis, and 29 completed the study. Thirty-eight treatment emergent adverse events (TEAEs) were reported by 20 participants (15 in the OXO-001 group and 5 in the placebo group). TEAEs were related to OXO-001 administration in 13.2, 10.5, and 15.8% of cases of the 100, 200, and 300 mg doses, respectively. None of the participants discontinued the study, and no serious AEs or deaths were record­ed. Differences in TEAEs by BMI were not found. The PK profile showed a fast absorption rate and proportional increases of OXO-001 plasma concentration to increasing doses, suggesting linear PK, with higher concentrations in BMI <25 kg/m2 group higher than in the ≥25 kg/m2 group. There were no relevant changes in vital signs, ECG, ovarian follicle development, endometrial morphology, and laboratory tests before and after the administration of OXO-001 or placebo.Conclusion: The administration of OXO-001 in volunteers of childbearing age was safe and well tolerated, with consistent PK linear profile within doses studied and without detrimental effect on endometrium or ovary-related variables, with similar effects in healthy weight and overweight participants. The maximum studied dose (300 mg/ day) was safe and well tolerated. These data are sufficient to support further clinical trials (registration number: 2016-001276-30).
