E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
This open-label, rater-blinded extension study will enroll patients who
have relapsing-remitting multiple sclerosis (RRMS) and who participated
in one of three prior Genzyme-sponsored studies of alemtuzumab
[CAMMS223, CAMMS323) also known as CARE-MS I, or CAMMS324 also
known as CARE-MS II]. The main purpose of this study is:
To examine the long term safety and efficacy of alemtuzumab treatment
in patients who received alemtuzumab as their study treatment in one of
the prior studies. |
|
E.2.2 | Secondary objectives of the trial |
To examine the safety and efficacy of initial alemtuzumab treatment in
this study for patients who received Rebif® (interferon beta-1a) as their
study treatment in one of the prior studies.
To determine if and when further alemtuzumab treatment is needed, and
the safety and efficacy of this "as needed" treatment. This applies both
to patients who received alemtuzumab for the first time in one of the
prior studies or for the first time in this extension study. |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
-QT Substudy (only in selected countries): To assess the potential effects of a 5-day, 12 mg/day, IV
alemtuzumab treatment cycle on cardiac repolarization as detected by
prolongation of the QT corrected (QTc) interval will be performed at
selected sites. Approximately 55 patients formerly treated with
interferon beta-1a in prior studies will be enrolled in which they will
have ECGs and corresponding pharmacokinetic (PK) samplings
performed prior to and during the cycle of alemtuzumab dosing.
-Biomarker: For research purposes and on a voluntary basis, a blood
sample will be collected from consenting patients for exploratory
analysis of generic variations related to MS disease and/or the effects of
alemtuzumab. |
|
E.3 | Principal inclusion criteria |
Patients must meet ONE of the following criteria to participate in the
Extension Study:
-Received alemtuzumab in CAMMS323 or CAMMS324, completed the 2-
year study period, and have not subsequently received disease
modifying treatments (other than glatiramer acetate or interferon beta);
or
-Received Rebif® in CAMMS323 or CAMMS324, completed the 2-year
study period, and have not subsequently received alternative disease
modifying treatments (other than glatiramer acetate or another
interferon beta); or
-Participated in CAMMS223.
NOTE: Criteria 1 and 2 above mean that patients who enrolled in
CAMMS323 or CAMMS324 but did not complete the 2-year study period
or went on to receive non-study drug DMTs after randomization are not eligible for inclusion in the Extension Study. Patients who enrolled in
CAMMS324 after participation in CAMMS223 must meet criteria 1 or 2 to be eligible for inclusion in the Extension Study. |
|
E.4 | Principal exclusion criteria |
Any alemtuzumab patient from CAMMS223, CAMMS323, or CAMMS324
who has received alemtuzumab off-label (ie, outside of one of the prior
Genzyme-sponsored studies) or is participating in any other
investigational study, unless approved by Genzyme. In addition, these
patients must be screened for disqualifying safety concerns before
receiving alemtuzumab retreatment.
Any Rebif® patient from CAMMS223, CAMMS323, or CAMMS324 who
meets any of the following criteria. In addition, these patients must be
screened for disqualifying safety concerns before receiving alemtuzumab treatment.
a)Does not wish to receive alemtuzumab;
b) Ongoing participation in any other investigational study , unless
approved by Genzyme;
c)Has received alemtuzumab off-label (ie, outside of one of the prior
Genzyme-sponsored studies);
d)Known bleeding disorder or therapeutic anticoagulation;
e)Diagnosis of idiopathic thrombocytopenia purpura or other
autoimmune hematologic abnormality;
f)History of malignancy, except basal cell skin carcinoma;
g)Intolerance of pulsed corticosteroids, especially a history of steroid
psychosis
h)Significant Autoimmune disorder (other than MS);
i)Major psychiatric disorder or epileptic seizures not adequately
controlled by treatment;
j)Active infection or high risk for infection
k)Unwilling to use a reliable and acceptable contraceptive method during
and for at least 6 months following each alemtuzumab treatment cycle
(fertile patients only). |
