Unble to complete all arms of the planned study due to Covid stoppage and difficulty with recruiting and getting enrolled participants to return post Covid.
Our primary limitation was stoppage due to Covid (our laboratory was forced to close). We also had a very challenging time recruiting subjects when we reopened after the three-month closure under new rules. Subjects who had been enrolled did not return, and new subjects were difficult to recruit. Thus, we were not able to complete all arms of the planned study. We were able to answer our primary questions regarding autonomic function in women with PCOS.

due to COVID-19
In April 2020 at time of planned interim analysis, decision was taken to prematurely stop the accrual due to COVID-19. Early termination led to small numbers of subject analyzed. The statistical plan was revised to propose the primary efficacy analysis in subgroup of patients with ICI secondary resistance (defined as progression after ICI second line >= to 12 weeks from stratification criteria based on biological and clinical rationale).

Inadequate resources to complete the study
In Mar. 2020 study placed on prolonged pause due to the pandemic. Research activities resumed with limitations later that year. The last study participant was screened in Feb. 2021. However, personnel departure affected study activities, so study was again paused, with plans to resume once adequate personnel were hired. However no additional support was provided. In Dec. 2022, it was decided to terminate the study when it became clear that resources would be insufficient to complete the trial.
