Inclusion Criteria:
1. Male and female subjects, 18-65 years of age, inclusive, at the time of informed
consent signature
2. RMS diagnosed according to the McDonald criteria
3. Currently receiving Rebif® 44mcg sc tiw using manual injections and/or Rebiject II
autoinjector for greater than or equal to twelve weeks
4. Capable of self-injecting using the RebiSmart™ autoinjector. Self- injecting is
defined as being able to make 2 of the 3 weekly injections without assistance.
5. Be willing and able to comply with the study procedures for the duration of the trial
6. Have given written informed consent and signed Health Insurance Portability and
Accountability Act (HIPAA) Authorization before any study- related activities are
carried out
7. Female subjects must not be either pregnant or breast-feeding and must lack
childbearing potential, as defined by either:
- Being post-menopausal or surgically sterile, or using a highly effective method
of contraception (defined as a method that results in a low failure rate (i.e.
less than 1% per year) when used consistently and correctly, and includes for
instance, implants, injectables, combined oral contraceptives*, some
intrauterine devices, sexual abstinence or vasectomised partner)
- Female subjects of childbearing potential must have a negative pregnancy test at
Screening and Study Day 1 to be included in the trial. A urine pregnancy test
will also be done at the Week 12/Exit visit
- Note for subjects using a hormonal contraceptive method: No formal drug
interaction studies have been carried out with Rebif®. As interferons have
been reported to exert an inhibitory activity on hepatic microsomal
enzymes, it is unlikely that the clearance of oral contraceptives would
increase and result in decreased efficacy. In over 10,000 patient years of
clinical trial experience with Rebif®, there has never been any indication
of an interaction with oral contraceptives.
Exclusion Criteria:
1. Have used any other injectable medications (e.g. for pain) on a regular basis during
the week prior to Screening or throughout the duration of the trial (the
administration of a single injection for treatment or prophylaxis of a condition
unrelated to MS or Rebif® therapy (e.g., influenza or pneumococcus vaccination) will
be acceptable)
2. Have received MS therapy other than Rebif® within twelve weeks prior to Screening or
at any time during the trial (e.g., other disease modifying drugs, Rebif® New
Formulation, combination therapy, immunomodulatory and/or immunosuppressive agents,
including but not limited to any other interferon (Avonex/Betaseron/Extavia),
glatiramer acetate (Copolymer I), cyclophosphamide, cyclosporine, methotrexate,
linomide, azathioprine, mitoxantrone, teriflunomide, laquinimod, cladribine,
fingolimod (FTY720), total lymphoid irradiation, anti-lymphocyte monoclonal antibody
treatment (e.g. natalizumab, alemtuzumab/Campath, anti-CD4), Intravenous
immunoglobulin (IVIg), cytokines or anti-cytokine therapy) and telbivudine
3. Have inadequate liver function, defined by a alanine aminotransferase (ALT) > 2.5x
upper limit of normal (ULN), or alkaline phosphatase > 2.5x ULN, or total bilirubin >
2.5x ULN
4. Have inadequate bone marrow reserve, defined as a total white blood cell count < 3.0x
109/L, platelet count < 75x109/L, hemoglobin < 100g/L
5. Have complete transverse myelitis or simultaneous-onset bilateral optic neuritis
6. Have a history of alcohol or drug abuse
7. Have thyroid dysfunction
8. Have moderate to severe renal impairment
9. Have a major medical or psychiatric illness that in the opinion of the investigator
creates undue risk to the subject or could affect compliance with the study protocol
10. Have a history of seizures not adequately controlled by treatment
11. Have serious or acute cardiac disease, such as uncontrolled dysrhythmias,
uncontrolled angina pectoris, cardiomyopathy, or uncontrolled congestive heart
failure
12. Have, in the opinion of the investigator, major visual, physical or cognitive
impairment that would preclude the subject from self-injecting with the RebiSmart™
autoinjector
13. Have a known hypersensitivity or allergy to interferon-beta or any of the excipients
14. Have participated in another clinical trial within the past thirty days
15. Are pregnant or attempting to conceive
16. Have previously used a RebiSmart™ autoinjector |
