A Phase 3 interventional study of RPH-104 in Idiopathic Recurrent Pericarditis, sponsored by R-Pharm International, LLC. Active, not recruiting at 1 site in Russian Federation. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-11-15.
Sponsored by R-Pharm International, LLC (part of R-Pharm) · Phase 3, Interventional, and Treatment
The goal of this clinical trial is to evaluate the safety and efficacy of RPH-104 for long-term use in a population of patients with idiopathic recurrent pericarditis who completed the main study CL04018068.
The primary objective of the study is to evaluate the safety of RPH-104 80 mg once every 2 weeks in patients with idiopathic recurrent pericarditis who completed the main study.
This long-term open-label study is an extension of the main double-blind, randomized, placebo-controlled study, CL04018068. This study will include the following periods:
It is planned that this study will include no more than 25 patients who completed the main study.
During the screening period, patients will be evaluated for eligibility for inclusion/non-inclusion in this study. Patients who do not meet these criteria will not receive treatment with the study drug.
Patients who meet the criteria for inclusion/non-inclusion in the study will enter the treatment period, where they will start open-label treatment with RPH-104 80 mg once every 2 weeks subcutaneously (SC).
The study drug to patients will be administered by qualified medical personnel every 2 weeks when the patient visits the study site, or at the patient's home by the patient him/herself. Safety and efficacy assessments are performed at Visit 1, Visit 2 (after 2 weeks) and then every 4 weeks according to the visits schedule.
After the patients receive the last dose of the study drug the treatment period will be considered completed and a 168 week period of safety follow-up will start. During this period, the patients will have to visit the study site after 4 weeks, then - after 8 weeks, and thereafter - every 12 weeks if in the Investigator's opinion it is considered safe and acceptable for a particular patient (it is possible to conduct the visits every 4 weeks until the completion of the study, if necessary in the Investigator's opinion and in agreement with Sponsor). There will also be eight telephone visits.
In case of a suspected recurrence of pericarditis, the patient will need to contact the study physician and come to the study site for an unscheduled visit. Recurrence of pericarditis is defined as the presence of at least two of the following symptoms in a patient:
If recurrence of the disease is confirmed during the treatment period as well as if any of the above-described signs of relapse of pericarditis and its persistence (two consecutive visits) or a tendency to increase the values of the sign (estimated at two consecutive visits) are detected, therapy with the study drug could be canceled ahead of schedule or continued at a dose of 80 mg every 2 weeks with the addition of NSAIDs and / or colchicine at the discretion of the Investigator.
If the patient develops a pericarditis recurrence during the safety follow-up period, at the discretion of the investigator treatment with the study drug might be re-initiated in this patient for a duration of 60 weeks or therapy with alternative drugs of the researcher's choice might be prescribed (in this case, the patient will have to come to two follow-up visits - 4 and 8 weeks after the last dose of the study drug and perform eight telephone visits after 20, 32, 44, 56, 68, 80, 92 and 104 weeks after the administration of the last dose of the study drug. After that the patient will be considered to have completed the study). In case of study drug re-initiation, the drug will be administered according to the following regimen: a single dose of 160 mg (first injection) followed by a dose of 80 mg 7 days and 14 days after the first injection and at doses of 80 mg every two weeks thereafter (at the discretion of the investigator). At the discretion of the investigator, NSAIDs and/or colchicine might be used for the treatment of recurrences in these patients.
The assessment of the patient's condition will be carried out 3 days, 7 and 14 days, as well as 12 weeks after the continuation of the study therapy with the addition of NSAIDs and / or colchicine during the therapy period or after the study drug re-initiation during the safety monitoring period. The criterion for the resolution of the relapse is the presence of all the following signs simultaneously:
If the recurrence of the disease is resolved by the week 12, the patient will continue to use RPH-104 80 mg every 2 weeks and will conduct efficacy and safety assessments every 2 weeks for 12 weeks and thereafter every 4 weeks until the end of the scheduled treatment period or re-initiated therapy, depending on the period the study when the recurrence occurred. If glucocorticoid prescription is required by week 12 to resolve a recurrence, the investigated therapy will be canceled to the patient ahead of schedule.
If the patient develops a pericarditis recurrence after the study drug re-initiation (the patient already receives RPH-104 80 mg every 2 weeks during the safety monitoring period), as well as if any of the signs of a relapse of pericarditis and its persistence or a tendency to increase the values of the sign (as described above for the period of planned therapy), the use of RPH-104 might be canceled ahead of schedule or continued until the end of the period of re-initiated therapy at a dose of 80 mg every 2 weeks with the addition of NSAIDs and/or colchicine at the discretion of the investigator.
After the end of the re-initiated therapy, the patient will have to come to two follow-up visits - 4 or 8 weeks after the last dose of the study drug and perform eight telephone visits after 20, 32, 44, 56, 68, 80, 92 and 104 weeks after the administration of the last dose of the study drug.
No decrease or increase in the doses of the study drug (other than those described in this study) are envisaged in this study.
Patients who have discontinued the open-label therapy with the study drug early for any reason, should perform two safety follow-up visits at Week 4 and Week 8 after the last dose of the study drug and perform eight telephone visits after 20, 32, 44, 56, 68, 80, 92 and 104 weeks after the administration of the last dose of the study drug.
The duration of one patient participation in this open study is from 192 to 228 weeks, depends on the duration of the therapy period, which will be calculated for each patient, taking into account the duration of the RPH-104 use during the main study (CL04018068), as well as on the absence or presence of a pericarditis recurrence and the decision to resume the studied therapy in the safety follow-up period of the study.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
