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.</p><p><strong>Conclusion: </strong>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).</p>","PeriodicalId":14080,"journal":{"name":"International Journal of Fertility & Sterility","volume":"19 2","pages":"177-185"},"PeriodicalIF":2.3,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11976879/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143811456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
