简要总结
The purpose of this study is to evaluate the efficacy of Relugolix (TAK-385) 40 mg administered orally once daily for 12 weeks, compared with leuprorelin injection (once every 4 weeks, 1.88 mg or 3.75 mg subcutaneously [SC]/time) in patients with uterine fibroids.
详细描述
The drug tested in this study was called Relugolix (TAK-385). Relugolix was tested to treat people who had uterine fibroids.
The study enrolled 281 patients. Participants received relugolix placebo and leuprorelin acetate placebo in run in period for 3 to 6 weeks. After run-in period, participants were randomly assigned (by chance, like flipping a coin) to one of the two treatment groups in 1:1 ratio:
- Relugolix 40 mg
- Leuprorelin 1.88 or 3.75 mg
Participants received relugolix tablets once daily along with leuprorelin 1.88 mg or 3.75 mg subcutaneous injection once in 4 weeks for 24 weeks in treatment period.
This multi-center trial was conducted in Japan. The overall time to participate in this study was approximately 32 to 40 weeks including run-in period of 3 to 6 weeks and a treatment period of 24 weeks. Participants will make multiple visits to the clinic, and a final visit 4 weeks after last dose of study drug for a follow-up assessment.

Percentage of Participants With Total PBAC Score of <10 From Week 6 to 12
时间窗: Week 6 to 12
PBAC score was used to measure volume of menstrual blood loss. Participants used sanitary products designated by sponsor and recorded the numbers of tampons or towels used, clots and flooding in patient diary. Three diagrams used which represented a lightly, moderately stained or completely saturated pad/tampon. Following scores assigned: 1) 1, 5, or 20 points for each pad; 2) 1, 5, or 10 points for each tampon; 3) 1 or 5 points for each blood clot of \<1 cm/=1 cm/\>1 in longest diameter; 4) 5 points for each episode of flooding. The total PBAC score (sum of points) ranges from 0 to \>500.
