Trial outcomes

Primary outcomes

1

Complete response rates within 28 weeks of treatment

The cumulative 28-week CR rates will be calculated in two groups. Patients will be evaluated with an hysteroscopy every 12 to 16 weeks. For some may delay the evaluation as personal reasons, we define the primary outcome measure as complete response rates within 28 weeks of treatment.

Time frame
Up to 28 weeks

Secondary outcomes

1

Adverse events

Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 will be recorded, as well as incidence of adverse events.

Time frame
Through study completion, an average of 28 weeks
2

Time to achieve complete response

The median CR time will be calculated.

Time frame
Up to 28 weeks
3

Relapse rates

Time frame
Through study completion, an average of 2 years
4

Rates of fertility outcomes

Time frame
Through study completion, an average of 2 years
