Condition(s) targeted: Multiple Sclerosis
Intervention: Avonex (Drug)
Phase: Phase 3
Status: Completed
Sponsored by: Biogen
Summary
The study is designed to determine the effect of weekly intramuscular (IM) administration of
30 mcg Avonex (interferon beta 1a) on safety parameters and gadolinium (Gd) enhanced and
T2-weighted cranial magnetic resonance imaging (MRI) lesions in Chinese patients with
clinically diagnosed (using revised McDonald criteria) relapsing multiple sclerosis (MS).
Clinical Details
Official title: An Open-Label Study to Evaluate the Safety and Tolerability and to Explore the Efficacy of Avonex (Interferon Beta-1a) in Chinese Subjects With Relapsing Multiple Sclerosis
Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: The number and proportion of subjects with adverse events (AEs)Assessment of clinical laboratory parameters Assessment of vital signs and physical examinations Assessment of electrocardiogram (ECG) Assessment of immunogenicity Incidence of depression Incidence of flu-like symptoms Subject assessment of injection site pain Clinical assessment of the injection site
Secondary outcome: Assess safety of Avonex by evaluating changes in the Expanded Disability Status Scale (EDSS) score over timeNumber of Gd-enhancing lesions on brain MRI scans taken after 3 and 6 months following Avonex treatment Number of new or newly enlarging T2-weighted lesions on brain MRI scans taken after 3 and 6 months following Avonex treatment Volume of T2-weighted lesions on brain MRI scans taken after 6 months following initiation of Avonex treatment Assess pharmacodynamic response to Avonex by evaluating the change from baseline in serum levels of neopterin
Detailed description:
This is a multicenter, open-label, safety study to support registration of Avonex in China
by providing data on the effect of weekly IM administration of 30mcg Avonex on safety
parameters in Chinese patients with clinically diagnosed relapsing MS. This study will also
include an intra-subject exploratory comparison of pre-treatment MRI (at - 3 months and at
month 0) and post - treatment MRI (at month 3 and month 6). Up to 60 subjects with relapsing
forms of MS will be recruited to approximately 6 sites in China.
The study period will consist of screening, a 6 month open-label treatment period, and
follow up at 30 days post-dosing. There will be a total of 8 clinic visits and 1 telephone
contact.
Screening: will be determined 3 months +/- 7 days prior to subjects' first dose of Avonex on
Day 1, at which time a screening MRI with and without Gd-enhancement will be performed.
Treatment Period: consists of eligible patients undergoing pre-dosing assessments and
receiving the first dose of Avonex on day 1. Subjects will have a brain MRI within 48 hours
prior to the first injection of Avonex.
Weekly doses of open-label Avonex 30mcg IM will be administered for 24 consecutive weeks for
a total of 25 injections per subject. Subjects or their caregivers will be allowed to
self-inject after successful completion of appropriate IM injection training.
Subjects will return to the clinic at weeks 6, 12, 18 and 24 for safety and laboratory
assessments (including blood sample collection for pharmacodynamic (neopterin) and
immunogenicity testing), and clinician injection site assessments. Subjects will undergo
brain MRI with and without Gd enhancement at week 12 and week 24. Subjects will perform
injection site pain assessments on day 1 and at weeks 6, 12, 18, and 24 recording results on
a visual analog scale. Subjects who prematurely discontinue Avonex may remain in the study
and continue protocol-scheduled visits/evaluations (with the exception of subject and
clinician injection site assessments and neopterin sample collection.
Subjects who experience new or worsening symptoms suggestive of an MS relapse will have a
neurological worsening visit within 5 days following onset of symptoms. Treatment of
confirmed MS relapses will follow a protocol-specified regimen.
Post treatment period: subjects will undergo follow-up assessment at week 24 (at 24+/- 8
hours following their last Avonex injection, if applicable). Subjects will have a telephone
follow up contact conducted 30 (+/- 7 days) after their last study visit to assess AEs and
use of concomitant medications.
Eligibility
Minimum age: 18 Years.
Maximum age: 55 Years.
Gender(s): Both.
Criteria:
Inclusion Criteria:
- Ability to understand risks of study and provide informed consent.
- Must be Chinese, aged 18 to 55 years inclusive at time of consent.
- Must have diagnosis of relapsing MS of 3 months duration at time of screening visit.
- Must have at least 1 documented MS attack within 3 years of Day 1.
- Must have EDSS score of 0 to 5 inclusive at screening visit.
- All male subjects & female subjects of child-bearing potential must practice
effective contraception during the study.
Exclusion Criteria:
- Have a diagnosis of primary progressive, secondary progressive, or progressive
relapsing MS.
- Have had a clinical MS attack within the 50 days prior to Day 1, and or the subject
has not stabilized from a previous attack in the opinion of the Investigator.
- The subject is unable to undergo a brain MRI scan for any reason.
- The subject's screening and Day 1 MRIs are both normal (negative) for lesions
consistent with MS (Gd-enhancing lesions are not required, but one of the 2 MRIs
should be consistent with MS).
- History of severe allergic or anaphylactic reactions.
- Known allergy to any component of the Avonex Formulation.
- History of any clinically significant cardiac, endocrinologic, hematologic, hepatic,
immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric,
renal or other major disease.
- Subjects with a history of malignant disease, including solid tumors, and hematologic
malignancies (except basal cell and squamous cell carcinomas of the skin that have
been completely excised and considered cured).
- History of seizure disorder or unexplained blackouts OR history of a seizure within 6
months prior to Day 1.
- History of suicidal ideation or an episode of clinically severe depression (as
determined by the Investigator) within 6 months prior to Day 1. Note: subjects
receiving ongoing antidepressant therapy will not be excluded from the study unless
the medication has been increased within the 6 months prior to Day 1.
- Clinically significant abnormal ECG values as determined by the Investigator.
- Known history of human immunodeficiency virus (HIV).
- Known history of, or positive test result for hepatitis C virus (test for hepatitis C
virus antibody HCV Ab) or hepatitis B virus (test for Hepatitis B surface Antigen
HBsAg) and/or Hepatitis B Core Antibody (HBcAb).
