Placebo Comparator

Participants received placebo weekly administered subcutaneously for 48 times in the double-blind treatment period.Once the participants relapse,they should advance to the open phase.All participants were treated with the test drugs.

Group Type EXPERIMENTAL

Placebo

Intervention Type BIOLOGICAL

Starting with the forty-ninth dose,the trial went into the open phase. All participants were treated with the test drugs.

RC18 160 mg

Patients received the test group RC18 160mg weekly administered subcutaneously for 48 times.Starting with the forty-ninth dose,the trial went into the open phase . All participants were treated with the test drugs.

Group Type EXPERIMENTAL

RC18 160 mg

Intervention Type BIOLOGICAL

In the Phase B,the researchers can adjust the dose of RC18 according to the subjects' willingness and recurrence, but the maximum dose of single dose should not exceed 320g.
