Conditions

Autoimmune Premature Ovarian Insufficiency

Brief summary

Egg retrieval (yes/no) in response to controlled ovarian hyperstimulation at 4 to 6 months post-rituximab treatment compared to placebo, as well as within the rituximab-treated group at 4 to 6 and 12 months after the last treatment session compared to baseline.

Detailed description

Occurrence of spontaneous menstrual bleeding (yes/no) at any point during the 19-month study period., Proportion of participants who achieve ovulation (defined as serum progesterone >10 nmol/L) at any time during the study period., Changes in B-cell count, auto-antibody indices, and immunoglobulin (IgG) levels from baseline to the end of the study period., Changes in serum follicle-stimulating hormone (FSH) and anti-Müllerian hormone (AMH) levels from baseline to the end of the study period., Changes in quality of life scores, as measured by validated instruments (AddiQol, PGWB, SF-36, and MRS), from baseline to the end of the study period., Safety endpoint: the incidence and severity of adverse events, hospital admissions, infections, allergic reactions and over stimulation in relation to the controlled ovarian hyperstimulation.
