E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objectives of this study are to examine: (1) the long-term safety and efficacy of alemtuzumab in multiple sclerosis (MS) patients who received alemtuzumab during prior Genzyme-sponsored studies including CAMMS223, CAMMS323, or CAMMS32400507 (referred to hereafter as CAMMS324); (2) the safety and efficacy of as-needed alemtuzumab retreatment in these previously alemtuzumab-treated patients; and (3) the safety and efficacy of 2 fixed annual alemtuzumab cycles followed by optional as-needed retreatment in patients who previously received subcutaneous interferon beta-1a (SC IFNB-1a) during these studies. |
|
E.2.2 | Secondary objectives of the trial |
The efficacy of immediate alemtuzumab treatment (IAT, ie, alemtuzumab initiated at onset of CAMMS323 or CAMMS324) vs. delayed alemtuzumab treatment (DAT, ie, alemtuzumab initiated after completing 2 years of CAMMS323 or CAMMS324) will also be examined. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Received alemtuzumab in CAMMS323 or CAMMS324, completed the 2-year study period, and have NOT subsequently received DMTs (other than glatiramer acetate or interferon beta) 2. Received SC IFNB-1a in CAMMS323 or CAMMS324, completed the 2-year study period, and have NOT subsequently received alternative DMTs (other than glatiramer acetate or another interferon beta) 3. Participated in CAMMS223 |
|
E.4 | Principal exclusion criteria |
Alemtuzumab treated patients: 1)Any patient who has received alemtuzumab off-label (ie, outside of one of the prior Genzyme studies) will be excluded from participating in this study. 2)Ongoing participation in any other investigational study, unless approved by Genzyme. Iin addition, alemtuzumab patients must be screened for disqualifying safety concerns (ref. prot. Sect. 9.2.3) before receiving retreatment. SC IFNB-1a treated patients: 1)Does not wish to receive alemtuzumab 2)Ongoing participation in any other investigational study 3)Has received alemtuzumab off-label (ie, outside of one of the prior Genzyme studies) 4)Known bleeding disorder (eg,dysfibrinogenemia,factor IX deficiency,hemophilia,Von Willebrand`s disease,Disseminated Intravascular Coagulation,fibrinogen deficiency,or other clotting factor deficiency) or therapeutic anticoagulation 5)Diagnosis of ITP,or other autoimmune hematologic abnormality.Patients who were diagnosed with ITP per the protocol definition in one of the prior studies can still be considered for the extension study if the ITP was not considered to be autoimmune. Such situations require prior approval by Genzyme 6)History of malignancy, except basal cell skin carcinoma 7)Intolerance of pulsed corticosteroids, especially a history of steroid psychosis 8)Significant autoimmune disease including but not limited to: immune cytopenias,rheumatoid arthritis,systemic lupus erythematosus,other connective tissue disorders,vasculitis,inflammatory bowel disease,severe psoriasis, or anti-GBM disease (also known as Goodpasture s disease) 9)Major psychiatric disorder or epileptic seizures not adequately controlled by treatment 10)Infection with hepatitis B or C virus, seropositivity for HIV 11)History of invasive fungal infections 12)Unwilling to agree to use a reliable and acceptable contraceptive method throughout the study period (fertile patients only). Reliable and effective contraceptive method(s) include: intrauterine device (IUD),hormonal-based contraception,surgical sterilization,abstinence or double-barrier contraception (condom and occlusive cap [diaphragm or cervical cap with spermicide]) |

E.5 End points |
E.5.1 | Primary end point(s) |
The long-term effects of alemtuzumab in patients who received alemtuzumab prior to the extension study (eg, in studies CAMMS223, CAMMS323, or CAMMS324) will be examined by: Summarizing the efficacy endpoints from prior study baseline through Extension Month 36 Summarizing the percentage of patients meeting criteria for as-needed retreatment (MRI vs relapse), and time to meeting criteria for retreatment The efficacy of alemtuzumab in patients who received SC IFNB-1a prior to the extension study will be evaluated using pre vs post alemtuzumab comparisons on the efficacy endpoints |
