E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine whether ofatumumab 3, 30 or 60 milligrams (mg) given subcutaneously (SQ), reduces the cumulative number of new T1 GdE brain lesions over a period of 12 weeks, as compared with placebo, in subjects with RRMS |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the robustness of the MRI efficacy of ofatumumab 3, 30 or 60
milligrams (mg) given subcutaneously (SQ) over the 24 week treatment period relative to the first 12 weeks of the treatment period
• To evaluate the safety and tolerability over a period of 24 weeks of a range of SQ ofatumumab doses in subjects with RRMS
• To make a preliminary assessment of the efficacy of a range of SQ doses of ofatumumab in subjects with RRMS based on frequency of clinical relapses over a period of 24 weeks
• To determine the extent of B-cell depletion for a range of SQ doses of ofatumumab in subjects with RRMS
• To determine the extent of B-cell repletion following cessation of SQ ofatumumab treatment within specified time periods in subjects with RRMS
• To evaluate the immunogenicity of SQ ofatumumab in subjects with RRMS

B. At least two confirmed relapses within the previous 2 years or
C. At least one relapse in the previous 2 years, with a GdE brain lesion on an MRI scan in the past year.
6. Expanded Disability Status Scale (EDSS) score of 0-5.5 (inclusive) at screening.
7. Neurologically stable with no evidence of relapse for at least 30 days prior to start of Screening and during the Screening Phase (subjects who relapse during the screening
Phase can be re-screened, once the relapse has resolved).
8. A female subject is eligible to enter the study if she is:
A. Of non-childbearing potential
B. Of childbearing potential and NOT pregnant or nursing, has a negative serum pregnancy test at screening, and agrees to one of the following:
a. Complete abstinence from intercourse for the period from consent into the study until 6 months after the last dose of investigational product; or,
b. Consistent and correct use of one of the following acceptable methods of birth control for the period from consent into the study until 6 months after the last dose of investigational product:
i. Oral contraceptives (either combined or progesterone only)
ii. Injectable progesterone
iii. Levonorgestrel implants
iv. Estrogenic vaginal ring
v. Percutaneous contraceptive patches
vi. Intrauterine device (IUD) or intrauterine system (IUS) with a documented failure
rate of <1% per year
vii. Male partner sterilization (vasectomy with documentation of azoospermia) prior to the female subject’s entry into the study; this male must be the sole partner for the subject
viii. Double barrier method: condom and an occlusive cap (diaphragm or
cervical/vault caps) with a vaginal spermicidal agent
(foam/gel/film/cream/suppository).
A female is considered “Non-childbearing potential” if she is status-post hysterectomy, status-post surgical removal of both ovaries, has current, documented tubal ligation, or is postmenopausal and >2 years without menses. Female subjects who are post-menopausal <2 years must be confirmed menopausal by Follicle Stimulating Hormone (FSH) and
estradiol levels.
A female is considered “childbearing potential” if she has functional ovaries, ducts, and uterus with no impairment that would cause sterility. This includes women with oligomenorrhea (even severe), and women who are perimenopausal or who have just begun to menstruate.
French subjects: In France, a subject will be eligible for inclusion in this study only if either affiliated to, or a beneficiary of, a social security category. |

3. Neurological findings consistent with Progressive Multifocal Leukoencephalopathy (PML) or confirmed PML (see Appendix 4, Section 11.4, for PML monitoring algorithm).
