简要总结
The purpose of this study is to assess safety and efficacy of the long-term treatment with RPH-104 at doses of 80 or 160 mg once every 2 weeks (q2w) in patients with familial Mediterranean fever (FMF) with colchicine resistance or intolerance (i.e. colchicine resistant, crFMF), who completed the core study, during which they received at least one dose of RPH-104 (i.e. study patient population).
详细描述
This study is a long-term open-label extension (OLE) of the core double blind randomized placebo-controlled study CL04018065. This OLE study will have the following periods:
- Screening period - 2 weeks (from signing an Informed Consent Form [ICF] at Visit 10 of the core study to Visit 1, Day 0 of this OLE study) - includes unblinding of the treatment groups determined in the core study (unless was unblinded previously) and determination of the eligibility criteria compliance for this study (all other screening procedures are performed after the completion of Visit 11 of the core study, which is also a Day 0 of this OLE study); All patients meeting the study inclusion/exclusion criteria according to the screening results will be transferred to the treatment period at the same day (Day 0) - the beginning of this period will be considered Visit 1 of this study
- Treatment period - All patients will be receiving RPH-104 treatment for 198 weeks in the open-label regimen (both patient and the Investigator, along with all study team will know which treatment is used) at the doses determined for them in the core study. Thus, the possible RPH-104 dose will be:
- 80 mg q2w subcutaneously (SC);
- 160 mg q2w SC
The first RPH-104 administration in this study will be performed at Visit 1. To maintain the q2w dosage regimen, the screening and the first open-label injection of RPH-104 (if the patient meets the study eligibility criteria) must be performed on the same day - Day 0 (which is also the day of Visit 11 of the core study) - i.e. the first administration in this study will be performed 2 weeks (±3 days) after the last administration in the core study.
Further, RPH-104 will be administered to patients q2w both during each scheduled visit to the study site (with safety and efficacy assessments according to the visits schedule), and during Drug Administration Visits (DAVs) at the study site or at the patient's accommodation An injection of the study drug to patients is performed by qualified medical personnel every 2 weeks when the patient visits the study site; it is also possible for the patients to self-administer the drug at home (for which patients will be appropriately trained and provided with the necessary quantity of the drug, materials for the injection (including special containers for their disposal) and proper drug transportation).

入选标准
- •The patient with Familial Mediterranean Fever (FMF) with resistance to or intolerance of colchicine, who completed the core study, during which he/she received at least one dose of RPH-
- •Voluntarily signed and dated Patient Informed Consent Form (ICF) for participation in this study.
- •The patient's ability and desire, according to the Investigator's discretion, to follow the schedule of visits, follow the study procedures and follow the Protocol requirements, including the following:
- •to visit the study site every 2 weeks for RPH-104 administration by qualified study site personnel
- •to learn the subcutaneous (SC) injection technique and self-administer RPH-104 at his/her accommodation as per the study Protocol
- •to agree with the qualified medical personnel visits to his/her accommodation for RPH-104 administration.
排除标准
- •Any medically significant event that was observed in a patient during his/her participation in the core study, as well as any other medical conditions (including psychiatric disorders) or laboratory abnormalities, which may increase the potential risk associated with participation in the study and treatment with RPH-104, or may affect the interpretation of the study results, and which, according to the Investigator's opinion, may lead to the patient's non-compliance with the study inclusion criteria.
- •Pregnant and/or lactating women or women planning pregnancy during the study or within 2 months after the last RPH-104 dose.
- •Women of childbearing potential, i.e. all females with physiological ability to conceive except for those with final cessation of menses, which should be determined retrospectively after 12 months of natural amenorrhea, i.e. amenorrhea with an appropriate clinical status, for example, at respective age, who do not agree to use highly effective contraceptives throughout the study, starting from the moment of signing the ICF and for at least 8 weeks after the last RPH-104 dose or Men who are sexually active and do not agree to use highly effective contraceptives throughout the study, starting from the moment of signing the ICF and for at least 8 weeks after the last RPH-104 dose.
- •Highly effective contraception methods include:
- •complete abstinence: if it corresponds to the preferred and conventional lifestyle of the subject. Periodic abstinence (e.g. calendar, ovulation, symptothermal, postovulation method) and interrupted coitus are not considered acceptable contraceptive methods;
- •female sterilization: surgical bilateral ovariectomy (with/without hysterectomy) or tubal ligation at least 6 weeks before the start of the core study. In a case of ovariectomy only, the female reproductive status should be verified by further hormonal test;
- •male sterilization (with documented absence of sperm in ejaculate post vasectomy) at least 6 months before the start of the core study. Vasectomized male partner should be the only partner of the participating female subject;
- •combination of any two of the following methods (a+b or a+c or b+c):
- •use of oral, injectable or implanted hormonal contraceptives; in a case of oral contraceptives, the woman should constantly use the same product as was used during the core study;
- •installation of an intrauterine device or contraceptive system;
- •use of barrier contraceptives: condom or occlusive cap (diaphragm or cervical cap/contraceptive vaginal ring) with spermicidal foam/gel/film/cream/vaginal suppository
- •The need for a therapy with any of the following products from the moment of signing the ICF till the study treatment period completion:
- •systemic glucocorticoids at a dose exceeding 0,2 mg/kg/day of prednisolone (or 0,16 mg/kg/day of methylprednisolone, or an equivalent dose of another glucocorticoid) orally;
