About
The purpose of this study is to evaluate the efficacy and safety of peginterferon beta-1a produced by CinnaGen compared with CinnoVex® (CinnaGen) in subjects with relapsing remitting multiple sclerosis (RRMS). All the participants will receive one of the following regimens: pegylated interferon beta-1a (CinnaGen), autoinjector (Physioject™), 125mcg, subcutaneous, every 2 weeks for 24 months or CinnoVex® (CinnaGen), prefilled syringes, 30mcg, intramuscular, once a week for 24 months. The primary objective of this study is to verify the non-inferiority of peginterferon beta-1a (CinnaGen) versus CinnoVex® (CinnaGen) in reducing the annualized relapse rate (ARR) in participants with relapsing remitting multiple sclerosis (RRMS) at 2 years.
The secondary objectives of this study are:
Full description
The purpose of this phase III, randomized, active control, parallel, non-inferiority, multicenter study is to verify the non-inferiority of peginterferon beta-1a produced by CinnaGen versus CinnoVex® (CinnaGen) in subjects with relapsing remitting multiple sclerosis (RRMS).
All the participants will receive one of the following regimens:
I. Pegylated interferon beta-1a (CinnaGen), autoinjector (Physioject™), 125mcg, subcutaneous, every 2 weeks for 24 months; II. Interferon beta-1a, CinnoVex® (CinnaGen), prefilled syringes, 30mcg, intramuscular, once a week for 24 months.
With the aim of ensuring the compliance and safety, in the first two months of the study, in each monthly visit, a trained expert nurse will be responsible for drug injection for both intervention groups and will train all patients for self-injection. By the end of the first two months to the end of the study, patients will self-inject the medication in both groups.
All other cares or medications will be allowed to continue by patients, except for disease modifying therapies (DMTs) and medicines which affect the immune system (e.g. immunosuppressants and immunomodulators). Any concomitant medication will be recorded for patients in their regular visits.
The primary objective of this study is to verify the non-inferiority of peginterferon beta-1a (CinnaGen) versus CinnoVex® (CinnaGen) in reducing the annualized relapse rate (ARR) in participants with relapsing remitting multiple sclerosis (RRMS) at 2 years.
The secondary objectives of this study are:
Sample size:
Group sample sizes of 76 in the experimental group and 76 in the active comparator group will achieve almost 80% power to detect non-inferiority using a one-sided, two-sample t-test. The margin of non-inferiority is 0.17. The true ratio of the means at which the power is evaluated is 1.00. The significance level of the test is 0.05. The coefficients of variation of both groups are assumed to be 0.4. The dropout rate is assumed to be 10%; hence 168 patients will be randomized.
Sequence generation:
The randomization plan of the patients will be carried out centrally using Cran-R version 3.2.3. Using permuted block randomization, blocks (length of each block is 4 or 2) will be made, for a total of 168 patients with 1:1 allocation ratio. Once the randomization has been made, each patient is given a code with which he/she will be identified throughout the study. The assigned code will be made up of 3 numbers (corresponding to the randomization number) and by 4 initials (corresponding to the 2 first letter of the first name, the 2 first letter of the first surname) and 2 numbers (center code). The randomization number will be assigned in a consecutive way.
Blinding:
Because of the different routes of administration of drugs in the study groups, patient blinding is not possible.
Data management:
Principal investigator is responsible for safe keeping of all patients' records at all times. Original hard copies of case report forms (CRFs) will be sent to Clinical Trial Consultants (CTCs) upon request and at the end of the study for data management. A copy of the records will be kept at the center. Sending and receiving of all patients' documents will be made after taking into consideration safety and security issues.
Principal investigator should set necessary schemes to control the quality of:
Data monitoring:
The objectives of the data quality control (QC) are:
QC will be started after inclusion of 30% of patients and will be ended before 80% of inclusion.
Two levels of QC will be performed:
Quality of CRF completion: At the time of CRF reception, the Local Study Team will review the completed CRFs in order to assess the completeness and the quality of completion. The Local Study Team (monitor or designee) is responsible to set up an action plan in order to improve the quality at site level. In case of systematic issue, the Local Study Team will inform the Corporate Study Team.
Central database checks: In addition to the standard data management activities, the following parameters will be systematically assessed as a part of the QC of the study, in country- and site-levels by the Study Central Team:
Principal investigators should set necessary schemes to control the quality of:

Inclusion criteria
Exclusion criteria
Primary progressive, secondary progressive, or progressive relapsing MS
Female subjects considering becoming pregnant while in the study or currently breastfeeding
Subjects for whom MRI was contraindicated, i.e., who had pacemakers or other contraindicated implanted metal devices, were allergic to gadolinium, or had claustrophobia that could not be medically managed.
Unwillingness or inability to comply with the requirements of the protocol including the presence of any condition (physical, mental or social) that was likely to affect the subject's ability to comply with the protocol.
Pre-specified laboratory abnormalities
History of any clinically significant (as determined by the Investigator) cardiac, endocrinologic, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric, and renal, or other major disease that would preclude participation in a clinical trial.
History of malignant disease, including solid tumors and hematologic malignancies (with the exception of basal cell and squamous cell carcinomas of the skin that have been completely excised and are considered cured).
History of seizure disorder or unexplained blackouts or history of a seizure within 3 months prior to baseline.
History of suicidal ideation within 3 months prior to Baseline or an episode of severe depression within 3 months prior to Baseline. Severe depression is defined as an episode of depression that requires hospitalization, or at the discretion of the Investigator.
Abnormal screening blood tests exceeding any of the limits defined below:
A MS relapse that has occurred within the 30 days prior to randomization and/or the subject has not been stabilized from a previous relapse prior to randomization (Day 1).
Elective surgery performed within 2 weeks prior to randomization (Day 1) or scheduled to be performed through the study interval.
Treatment with other agents to treat MS symptoms or underlying disease as specified below:
Agent Time Required off Agent Prior to Baseline:
Any prior treatment with:
Prior treatment within 1 year of randomization:
Prior treatment within 6 months prior to randomization:
Subjects must have discontinued interferon treatment at least 6 months prior to randomization
Prior treatment within 30 days prior to randomization:
Prior treatment with glatiramer acetate within 4 weeks prior to randomization
Treatment with another investigational drug or approved therapy for investigational use within the 6 months prior to randomization
Other unspecified reasons that, in the opinion of the Investigator, made the subject unsuitable for enrolment
