treatment course to reduce serious reactions 
temporally associated with LEMTRADA infusion: 
• 
Pre-infusion: Physicians should obtain a 
baseline ECG and vital signs (including heart rate 
and blood pressure measurement), screen for pre-
existing hemorrhagic, cardiovascular (including 
venous thromboembolism) and cerebrovascular 
risk factors, screen for lung disease, review 
concomitant medications (eg, antiplatelet agents, 
anticoagulants), perform laboratory tests (complete 
blood count with differential, serum transaminases, 
serum creatinine, test of thyroid function and 
urinalysis with microscopy), evaluate infusion-
related risks, and review HCP checklist. It is at 
investigator’s discretion to re-treat or not re-treat 
patient with alemtuzumab after clinical evaluation. 
 
Updated the during infusion with following text: 
The following are recommendations in case of

(myocardial ischemia, hemorrhagic stroke, 
cervico-cephalic arterial dissection or 
pulmonary alveolar hemorrhage) should be 
closely monitored until complete resolution of 
the symptoms. The observation time should 
be extended as appropriate. 
- The patients should be educated on the 
potential for delayed onset of infusion 
associated reactions and symptoms and 
signs of cardiovascular or cerebrovascular 
events, and instructed to report symptoms 
and seek appropriate medical care.

PHASE OF DEVELOPMENT 
Phase 3B/4 
STUDY OBJECTIVE(S) 
Primary objective 
 
To evaluate long-term safety of alemtuzumab. 
Secondary objective(s)  
 
To evaluate long term efficacy of alemtuzumab. 
 
To evaluate the safety profile of patients who received other Disease 
Modifying Treatments (DMT) following alemtuzumab treatment.  
 
To evaluate patient-reported quality of life (QoL) outcomes and health 
resource utilization of patients who received alemtuzumab. 
 
To evaluate as needed re-treatment with alemtuzumab and other 
DMTs. 
STUDY DESIGN 
This study is a Phase 3B/4, international, multicenter, open-label, non-
comparative study to evaluate the long-term safety, efficacy and QoL of 
alemtuzumab in patients who have completed at least 48 months of the extension 
Study CAMMS03409. In addition, impact of treatment on pharmaco-economic 
data will also be evaluated. 
Scheduled visits for safety and efficacy assessments will be performed every 
six months. Quality of life and pharmaco-economic data will be collected every 
twelve months. 
Patients must contact the treating neurologist at the study site (Study 
Investigator) as soon as they experience any sign or symptom of multiple 
sclerosis (MS) relapse. The Study Investigator will decide on the need to 
schedule extra visits (unscheduled visits) to evaluate the patient’s status. 
At the Study Investigator’s discretion patients can be treated with additional 
courses of alemtuzumab (not sooner than 12 months from the previous course) or 
with any commercial DMT. 
If the patient is re-treated with additional courses of alemtuzumab, the patient will 
be followed using the specific recommendations indicated in the IB or in the local 
approved label (when available). Patients will be followed for 48-months after the 
last infusion of alemtuzumab received in the current trial setting. During the 
48-month period, laboratory safety sampling should be collected every month, in 
a local laboratory and they must be reviewed in a timely manner by the Study 
Investigator.  
If the 48-month period of safety follow-up continues after the study ends, the 
patient will be followed by their physician in a regular healthcare setting, in line 
with the local approved Risk Minimization Plan for alemtuzumab, until the 
48-month period is completed.

A pharmacogenomics (PGx) substudy will be conducted for exploratory analysis 
of genetic variations predictive of autoimmune conditions, including thyroid and 
immune thrombocytopenia (ITP), related to MS disease and/or the effects of 
alemtuzumab. For research purposes only and on a voluntary basis, a blood 
sample will be proposed to approximately 300 ongoing patients in the TOPAZ 
study who have not provided a PGx sample in the previous studies 
(CAMMS03409, CAMMS223, CAMMS323 and CAMMS324). A blood sample will 
be collected from consenting patients.  
Objectives of the substudy are as follows:  
 
To develop biomarkers predictive of autoimmune conditions including 
thyroid disorders and immune thrombocytopenia. This will include 
collection of samples from patients who have not yet developed any 
auto immune conditions; these samples would be used as controls.  
 
To explore efficacy and safety markers through data analysis. 
 
To explore genetic variation related to MS disease manifestation 
through data analysis. 
Sample collection, handling, storage, and analysis will conform to all applicable 
national guidance and regulations. Details of the PGx sub-study are presented in 
Appendix C.

ASSESSMENT SCHEDULE 
Safety assessments will be made at each visit and include all AEs, SAEs, and 
AESI. Vital signs will be assessed and recorded at each visit. Physical 
examination will be assessed and recorded once a year. 
Efficacy Assessments will be performed as described in the flowchart, including 
Expanded Disability Status Scale (EDSS); Brain imaging; MOS 36-Item 
Short-Form Health Survey (SF-36); FAMS and EQ-5D questionnaires.  
Potential MS relapse will be considered at each scheduled visit by the Study 
Investigator. Patients will be informed to contact the treating neurologist at the 
study site (Study Investigator) as soon as they observe any sign/symptom 
compatible with a possible relapse between scheduled visits and the Study 
Investigator will determine the need for an unscheduled visit. 
In case of relapse, the Study Investigator will decide on the therapeutic approach. 
The reason(s) for any change in the MS therapy must be collected as well as the 
relapse treatment. 
If the patient is re-treated with a new course of alemtuzumab, the patient will be 
followed during the 48-month period of safety follow-up after the last infusion of 
alemtuzumab. For patients treated with alemtuzumab, laboratory safety sampling 
should be collected every month for 48 months, in a local laboratory and the 
results will be reviewed in a timely manner by the Study Investigator.  
If the 48-month period of safety follow-up continues after the study ends, the 
patient will be followed by their physician in a regular healthcare setting until the 
48-month period is completed. 
PGx samples obtained from consenting patients will be used for exploratory 
biomarker analysis.

STATISTICAL CONSIDERATIONS The following represents an overview of planned analyses. Further elaboration of 
statistical issues will be specified in the Statistical Analysis Plan (SAP). 
Safety Analysis: 
All patients will be evaluated for safety based on incidence, duration, 
grade/intensity, seriousness, and relationship of AEs to alemtuzumab. AESIs, 
deaths, and other SAEs will also be evaluated.  
Efficacy Analysis: 
The long-term effects of alemtuzumab will be examined by summarizing the 
efficacy endpoints, including ARR, proportion of patients relapse free, changes in 
EDSS score over time, changes in MRI, QoL, changes in the FAMS, EQ-5d and 
pharmaco-economy, from original study baseline through the last visit in the 
study. 
DURATION OF STUDY  
The study duration will be 5 years (plus a window of 6 months) counted from the 
enrolment date of the first patient.

Monthly safety laboratory assessment will be performed in local laboratories at the patients’ convenience. 
a If not performed in the previous 12 months. In addition, an HPV screening should be performed approximately 1 year after the last alemtuzumab infusion date, and then every 12 months until the 48 months safety 
follow-up is completed. For women patients re-treated with alemtuzumab during the study, an HPV screening should be performed prior to re-treatment (if not performed in the previous 12 months) and then 
every 12 months until the 48 months safety follow-up is completed. 
b If not performed in the previous 2 weeks. LFT includes: ALT, AST, ALP, albumin, total protein, total bilirubin, and direct bilirubin.

INTRODUCTION AND RATIONALE  
Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) that 
affects approximately 2.5 million people worldwide (1). Its clinical course is typically 
characterized by initial episodes of transient neurological compromise with full recovery, 
followed by a phase of cumulative deficits that may increase with each new episode. Most 
relapsing patients eventually develop secondary progression leading to a constellation of chronic 
sequelae including profound muscle weakness, impaired gait and mobility, bladder and bowel 
dysfunction, and cognitive and visual impairments.  
MS is believed to arise from the interplay of polygenic inherited susceptibility and as yet 
unidentified environmental agents. Age of onset typically ranges from 10 to 59 years, with most 
cases occurring between 20 and 40 years of age. As with most other autoimmune disorders, MS is 
more than twice as common among women. Pathologically, MS is characterized by focal and 
non-focal tissue injury of the brain and spinal cord due to the complex interplay of inflammation, 
demyelination, axonal injury, astrocytosis, and tissue atrophy. Lymphocytes are believed to play 
a central role in MS pathogenesis.  
Alemtuzumab (Lemtrada®) is a humanized monoclonal antibody that binds to CD52, a cell 
surface antigen present at high levels on T and B lymphocytes, and at lower levels on natural 
killer cells, monocytes, and macrophages (2). 
There is little or no CD52 detected on neutrophils, plasma cells, or bone marrow stem cells. 
Alemtuzumab acts through antibody-dependent cellular cytolysis and complement mediated lysis 
following cell surface binding to T and B lymphocytes. 
The mechanism by which alemtuzumab exerts its therapeutic effects in MS is unknown, but may 
involve immunomodulation through the depletion and repopulation of lymphocytes. 
Research suggests that potential immunomodulatory effects in MS may include alterations in the 
number, proportions, and properties of some lymphocyte subsets post-treatment (3). 
Pilot studies in MS patients were conducted at Addenbrooke’s Hospital in the United Kingdom 
(UK). Genzyme Corporation (Genzyme, a Sanofi company) has sponsored Phase 2 and Phase 3 
randomized, comparator-controlled studies in patients with relapsing remitting MS that have 
established superior efficacy for alemtuzumab compared with subcutaneous interferon beta-1a 
(SC IFNB-1a, Rebif®) on clinical and imaging endpoints (4, 5, 6, 7, 8).  
Identified risks of alemtuzumab in patients with MS include:  
 Infusion-associated reactions (IAR)  
 Serious infections  
 Autoimmunity (notably, Immune thrombocytopenic purpura (ITP), thyroid dysfunction 
and nephropathies) 
The most important adverse reactions are autoimmunity (eg, ITP, thyroid disorders, 
nephropathies, cytopenias), IARs, and serious infections. The most common adverse events

reported after alemtuzumab treatment (in ≥20% of patients) are rash, headache, pyrexia, and 
respiratory tract infections. Of note, Listeriosis/Listeria meningitis has been reported in 
LEMTRADA treated patients, generally within one month of LEMTRADA infusion. To reduce 
the risk of infection, patients receiving LEMTRADA should avoid ingestion of uncooked or 
undercooked meats, soft cheeses and unpasteurized dairy products two weeks prior to, during, and 
for at least one month after LEMTRADA infusion. 
The Sponsor has conducted a comprehensive review of safety data from post-marketing use of 
alemtuzumab and added the following to the current list of AESIs: 
• 
Autoimmune hepatitis 
• 
Acquired hemophilia A 
• 
Hemophagocytic lymphohistocytosis (HLH) 
• 
Progressive multifocal leukoencephalopathy (PML) 
• 
Temporally associated* pulmonary alveolar hemorrhage 
• 
Temporally associated* myocardial ischemia, myocardial infarction 
• 
Temporally associated* stroke 
• 
Temporally associated* cervicocephalic arterial dissection 
* Temporally associated: 1 to 3 days after the last infusion 
Cases of serious and life‐threatening stroke (including hemorrhagic and ischemic), myocardial 
infarction and cervicocephalic (ie, vertebral, carotid) arterial dissection have been reported within 
three days of alemtuzumab administration, with most cases occurring within one day. Cases of 
pulmonary alveolar hemorrhage have been reported with onset within 48 hours of alemtuzumab 
infusion. Long term auto immune risks, such as cases of Hemophagocytic lymphohistiocytosis 
(HLH) and autoimmune hepatitis causing clinically significant liver injury, including acute liver 
failure requiring transplant, has been reported. To minimize the risk of these serious adverse 
events, recommendations are provided for infusion related management and long term safety 
monitoring for patients receiving re-treatment of alemtuzumab during the course of the trial:  
 Pre infusion: assess overall health status and risk factors; baseline BP/HR, bleeding risk, 
platelets count. Baseline liver function test. 
 During infusion: continuous or hourly monitoring BP/HR; intermittently ambulation, 
compressive stocking. 
 Post infusion: inform/remind patient any abnormal clinical sign/symptoms related to 
infusion. 
 Periodic liver function test.

Study CAMMS03409 is an open-label extension study designed to provide additional safety 
monitoring for up to 60 months, and as-needed alemtuzumab retreatment to qualifying patients 
who received alemtuzumab in prior Genzyme-sponsored studies CAMMS223, CAMMS323 and 
CAMMS324. In addition, patients who received SC IFNB-1a in the earlier studies had the 
opportunity to receive 2 annual courses of alemtuzumab, and possibly subsequent as-needed 
alemtuzumab retreatment. 
In CAMMS03409, “as needed” retreatment with alemtuzumab could be offered to patients upon 
documented evidence of resumed MS disease activity, subject to safety-related disqualifications. 
The additional course(s) of alemtuzumab were administered at 12 mg/day on 3 consecutive days 
(36 mg total dose) at least 12 months after the prior treatment course. The benefits and risks of 
>2 treatment courses have not been fully established, but results suggest that the safety profile 
does not appear to change with additional courses.  
The present study LPS13649 will provide long term safety and efficacy data on the patients who 
completed the extension study CAMMS03409, as well as on additional as-needed alemtuzumab 
retreatment. In addition, the study will provide information about the safety profile of patients 
who received other commercial DMTs following alemtuzumab treatment.

STUDY DESIGN  
6.1 
DESCRIPTION OF THE PROTOCOL  
This study is a Phase 3B/4, international, multicenter, open-label, non-comparative study to 
evaluate the long-term safety, efficacy and QoL of alemtuzumab in patients who have completed 
at least 48 months of the extension study CAMMS03409. In addition, impact of treatment on 
pharmaco-economic data will be evaluated. 
Patients treated with alemtuzumab within 48 months prior to enrollment in the LPS13649 study 
must be followed-up at monthly intervals until 48 months after the last infusion of alemtuzumab 
(Section 10.1.6.2).  
Scheduled visits for safety and efficacy assessments will be performed every six months. AEs and 
concomitant medications will be monitored continuously. Quality of life, pharmaco-economic 
data and brain imaging will be collected every twelve months. 
Patients must contact the treating neurologist at the study site (Study Investigator) as soon as they 
experience any sign or symptom of MS relapse. The Study Investigator will decide on the need to 
schedule extra visits (unscheduled visits) to evaluate the patient’s status. All procedures and 
assessments will be collected in the e-CRF. 
At the Study Investigator discretion patients can be treated: 
 Patients may receive additional courses of alemtuzumab but not sooner than 12 months 
from any previous alemtuzumab treatment course, or  
 Patients may receive other commercial DMTs. 
In the event that a Study Investigator decides to treat a patient (with alemtuzumab or another 
DMT) the factors contributing to the decision to treat (eg, patient is experiencing clinical and/or 
imaging activity) should be documented in the e-CRF.  
For treatment courses of alemtuzumab the Study Investigator should refer to the safety 
information in the Investigator’s Brochure (IB) or in the approved label in the country/region 
when available. All treatment courses will consist of 12 mg/day alemtuzumab intravenously 
infused once daily on 3 days (Section 8.1). 
If the patient is re-treated with additional courses of alemtuzumab, the patient will be followed 
using the specific recommendations indicated in the IB or in the local approved label (when 
available). Patients will be followed for 48-months after the last infusion of alemtuzumab received 
in the current trial setting. During the 48-month period, laboratory safety sampling should be 
collected every month, in a local laboratory and they must be reviewed in a timely manner by the 
Study Investigator.

If the 48-month period of required safety follow-up continues after the study ends, the patient will 
be followed by their physician in a regular healthcare setting, in line with the local approved Risk 
Minimization Plan for alemtuzumab, until the 48-month period is completed. 
A pharmacogenomics (PGx) substudy will be conducted for exploratory analysis of genetic 
variations predictive of autoimmune conditions, including thyroid disorders and immune 
thrombocytopenia (ITP), related to MS disease and/or the effects of alemtuzumab. Objectives of 
the substudy are as follows:  
 To develop biomarkers predictive of autoimmune conditions including thyroid disorders 
and immune thrombocytopenia. This will include collection of samples from patients who 
have not yet developed any auto immune conditions; these samples would be used as 
controls.  
 To explore efficacy and safety markers through data analysis. 
 To explore genetic variation related to MS disease manifestation through data analysis. 
For research purposes only and on a voluntary basis, a blood sample will be collected from 
approximately 300 ongoing patients who signed the optional pharmacogenomic informed consent 
form and who have not previously provided a PGx sample. Details of the PGx substudy are 
presented in Appendix C, “Exploratory Pharmacogenomics Assessment Substudy”.

 Alemtuzumab. 
Pharmaceutical form:  
 Concentrate for solution for infusion (sterile concentrate). 
Dose of drug per administration:  
 12 mg/day on 3 consecutive days (36 mg total dose).  
 Missed doses should not be given on the same day as a scheduled dose. 
Route of administration: 
 Intravenous infusion. 
8.1.1 Administration  
There is no fixed treatment requirement or schedule. Administration of alemtuzumab will only be 
done following a decision from the Study Investigator that an additional “as needed” course is 
indicated.  
Alemtuzumab will be then administered by IV infusions in a supervised medical setting at a dose 
of 12 mg/day on 3 consecutive days (36 mg total dose) at least 12 months after the prior treatment 
course.  
8.1.1.1 Method of preparation at the clinical site  
Alemtuzumab must be diluted before infusion. The diluted solution should be administered by 
intravenous infusion over a period of approximately 4 hours. 
8.1.1.2 Special precautions for disposal and other handling  
The vial contents should be inspected for particulate matter and discoloration prior to 
administration. Do not use if particulate matter is present or the concentrate is discolored. Do not 
shake the vials prior to use.  
For intravenous administration, withdraw 1.2 mL of alemtuzumab from the vial into a syringe 
using aseptic technique. Inject into 100 mL of sodium chloride 9 mg/mL (0.9%) solution for 
infusion or glucose (5%) solution for infusion. This medicinal product must not be diluted with 
other solvents. The bag should be inverted gently to mix the solution.

1.2 mL of solution. The vials are single use only and contain no preservatives. The label text for 
the alemtuzumab vial will, at a minimum, include the protocol number, the contents of the vial 
(ie, alemtuzumab 10 mg/mL, 1.2 mL vial), lot number, appropriate cautionary statements, route of 
administration, storage conditions, and name and address of Genzyme (a Sanofi company). Labels 
comply with Good Manufacturing Practices and national legislation. 
8.6 
STORAGE CONDITIONS AND SHELF LIFE  
Alemtuzumab, in vials, should be stored at 2° to 8°C (36 to 46°F). Do not freeze. Do not use 
alemtuzumab beyond the use by date provided on the label or other documentation. Protect from light.  
Alemtuzumab diluted product may be stored at room temperature (15° to 25°C) or refrigerated 
conditions (2° to 8°C), and should be used within 8 hours after dilution. From a microbiological 
point of view, it is recommended that the product should be used immediately. Protect from light. 
Partially used, unused, or damaged drug vials should be disposed according to institutional policies.  
Alemtuzumab will be used in accordance with the approved protocol and must not be used for any 
other purpose. 
8.7 
RESPONSIBILITIES  
The Study Investigator, the hospital pharmacist, or other personnel allowed to store and dispense 
the IMP will be responsible for ensuring that the IMP used in the clinical trial is securely 
maintained as specified by the Sponsor and in accordance with applicable regulatory 
requirements. 
All IMP will be dispensed in accordance with the Study Investigator's prescription and it is the 
Investigator’s responsibility to ensure that an accurate record of IMP issued and returned is 
maintained. 
Any quality issue noticed with the receipt or use of an IMP (deficiency in condition, appearance, 
pertaining documentation, labeling, expiration date, etc) should be promptly notified to the 
Sponsor. Some deficiencies may be recorded through a complaint procedure. 
A potential defect in the quality of IMP may be subject to initiation of a recall procedure by the 
Sponsor. In this case, the Study Investigator will be responsible for promptly addressing any 
request made by the Sponsor, in order to recall IMP and eliminate potential hazards. 
Under no circumstances will the Study Investigator supply IMP to a third party, allow the IMP to 
be used other than as directed by this clinical trial protocol, or dispose of IMP in any other 
manner.

8.7.1 Treatment accountability and compliance  
As alemtuzumab will be administered by daily IV infusions in a supervised medical setting, on an 
outpatient basis, by qualified center personnel, responsibility for compliance with mandatory 
safety assessments resides with the Study Investigator.  
8.7.2 Return and/or destruction of treatments  
The Study Investigator will not destroy the unused IMP unless the Sponsor provides written 
authorization. A detailed treatment log of the destroyed IMP will be established with the Study 
Investigator (or the pharmacist) and countersigned by the Study Investigator and the monitoring 
team.  
8.8 
CONCOMITANT MEDICATION  
A concomitant medication is any treatment received by the patient concomitantly to any IMP(s). 
In the current study, all medications received by the patient from the end of the Extension Study 
CAMMS03409 to Visit 1 of LPS13649 study, and during the study until the last visit will be 
collected. 
Patients who need to be re-treated with alemtuzumab and who are receiving treatment with other 
DMTs, should discontinue the other DMTs according to their local approved label. The potential 
for additive effects on the patient’s immune system must be taken into account. Concomitant use 
of alemtuzumab with some therapies could increase the risk of immunosuppression. 
8.8.1 Forbidden concomitant medications  
Patients should not receive live vaccines 6 weeks prior to alemtuzumab administration or during 
the study. 
All the specific recommendations indicated in the IB or in the local approved label (when 
available) should be checked before starting the re-treatment with alemtuzumab.

9.5.3 Vital signs  
The following vital signs will be recorded: systolic and diastolic blood pressure (millimeters of 
mercury [mm Hg]), heart rate (beats/minute), respiratory rate (breaths/minute), and temperature 
(degrees Celsius [°C]). 
 For all the patients: vital signs will be recorded at selection visit (D1) (if not recorded in 
the previous 3 months) and then every 6 months. 
 For patients treated with alemtuzumab: on days when alemtuzumab is infused, vital signs 
will be recorded before steroid administration, at a time after steroid administration (prior 
to alemtuzumab infusion), and 1 hour after the start of alemtuzumab infusion and hourly 
during and after infusion until observation post-infusion has ended (two hours after the 
end of the infusion or until stabilization). 
If clinically significant vital sign changes from previous visit are noted the changes will be 
documented as AEs in the e-CRF. Clinical significance is defined as any variation that has 
medical relevance and may result in an alteration in medical care. The Study Investigator will

9.5.4 Physical examination  
A physical examination, including weight, will be performed at D1 (if not performed in the 
previous 3 months) and then every 12 months. Any clinically significant abnormalities should be 
reported in the patient e-CRF as an AE. Weight should be taken with the patient wearing 
undergarments or very light clothing and no shoes and with an empty bladder. It is recommended 
to use the same scale throughout the study. 
9.6 
EFFICACY MEASUREMENTS  
9.6.1 Relapse  
Relapse is defined as new neurological symptoms or worsening of previous neurological 
symptoms with an objective change on neurological examination. Symptoms must be attributable 
to MS, last at least 48 hours, be present at normal body temperature (ie, no infection, excessive 
exercise, or excessively high ambient temperature), and be preceded by at least 30 days of clinical 
stability. 
EDSS must be completed to confirm the relapse. 
If the MS relapse is confirmed, the therapeutic approach will be decided by the Study 
Investigator, and all the treatments will be described in the e-CRF. Patients will be followed up at 
the discretion of the Study Investigator and all the procedures and assessments will be collected in 
the e-CRF. 
MS relapse will be verified at each visit. On the other hand, patients will be informed to contact 
the Study Investigator as soon as they observe any sign/symptom compatible with a possible 
relapse, in order to schedule an extra visit (see Section 10.1.4). 
Relapses will not be considered as AEs (see Section 10.4.1.2). 
9.6.2 Expanded disability status scale (EDSS)  
Patient disability will be evaluated using the EDSS, which has long been considered the standard 
for assessing disability in patients with MS. The EDSS must be performed by a qualified 
practitioner who has completed the Neurostatus certification training.  
The EDSS is an ordinal clinical rating scale which ranges from 0 (normal neurologic examination) 
to 10 (death due to MS) in half-point increments. Briefly, the assessing neurologist rates 
7 functional systems (pyramidal, cerebellar, brainstem, sensory, bowel and bladder, visual, 
cerebral, and other) in the context of a standard neurological examination and then uses these 
ratings in conjunction with observations and information concerning the patient’s mobility, gait, 
and use of assistive devices to assign an EDSS score. EDSS steps 1.0 to 4.5 refer to people with 
MS who are fully ambulatory, while EDSS steps 5.0 to 9.5 are defined by the impairment to 
ambulation.

Page 38 
EDSS will be collected at D1 (if not collected in the previous 3 months) and then at each 
scheduled visit (every 6 months) and unscheduled visits for MS relapse. 
9.6.3 Brain imaging  
Brain imaging will be performed at D1 (if not performed in the previous 6 months) and then every 
12 months. It will be also performed at the end of study visit, if not performed in the previous 
6 months. MRIs will be read and interpreted locally by qualified site personnel and/or designee 
(eg, neuroradiologist). MRIs should be reviewed locally by qualified site personnel for signs of 
Non-MS pathology. For study purposes, per-protocol scans will be also submitted to a central 
imaging vendor for scan quality control and analysis. 
9.6.3.1 Pre- and post-Gadolinium-MRI  
The most frequently used surrogate marker of inflammatory disease activity in Phase 1 and 
Phase 2 studies in MS is the rate of new gadolinium-enhancing MRI lesion formation. 
Gadolinium-enhancing lesions in MS patients generally indicate active foci of inflammatory 
demyelination in the CNS. In 2 studies, alemtuzumab has been shown to have a profound effect 
on this measure.  
Gadolinium-containing contrast agents have been linked with Nephrogenic Systemic 
Fibrosis/Nephrogenic Fibrosing Dermopathy (NSF/NFD) in patients with impaired kidney 
function. There have been no reported cases in alemtuzumab-treated MS patients to date. 
Nonetheless, the Study Investigator should confirm that the patient is eligible to receive 
gadolinium according to their imaging center’s guidelines, for example based on age, medical 
status, and most recent creatinine level, prior to performing gadolinium-enhanced imaging. 
9.6.3.2 MRI-T1  
These brain scans can be used to assess the number and volume of T1 hypointense lesions 
(“Black Holes”), which also indicate axonal loss and tissue matrix damage. Three dimensional 
(3D) T1 weighted Gradient Echo imaging will also be performed as it affords greater spatial 
resolution and thus enhances detection of smaller lesions. 
9.6.3.3 MRI-T2  
The total MRI T2 lesion volume has been used as a surrogate marker of disease activity in the 
beta-interferon studies. T2-weighted MRI assessments will also include proton density and fluid 
attenuated inversion recovery (FLAIR) sequences. The inflammatory demyelination and edema 
characteristic of active MS lesions as well as the sclerotic gliosis of end-stage MS plaques 
contribute to the MRI T2 lesion volume, which thus reflects the “burden of disease” in these 
patients.  
Cerebral volume is also estimated from MRI-T2/PD acquisitions to quantify global 
neuro-degeneration, which is largely due to axonal loss in MS. In this study the rate of cerebral 
atrophy will be determined from the MRI T2/PD brain scans as changes in the BPF.

9.6.4 MOS 36-item short-form health survey (SF-36) Version 2  
The SF-36 is a self-administered questionnaire designed to assess generic Health Related Quality 
of Life (HRQoL) in healthy and ill adult populations. The SF-36 consists of 36 items organized 
into the 8 scales shown below (see Table 1). The SF-36 also yields 2 summary measures of 
physical health (the Physical Component Summary [PCS]) and mental health (the Mental 
Component Summary [MCS]) derived from scale aggregates. Higher global scores are associated 
with better quality of life.

The reliability of the 8 scales and 2 summary measures has been estimated using both internal 
consistency and test-retest methods. With rare exceptions, published reliability statistics have 
exceeded the minimum standard of 0.70 recommended for measures used in group comparisons in 
more than 25 studies; most have exceeded 0.80. Reliability estimates for physical and mental 
summary scores usually exceed 0.90. 
SF-36 will be collected at D1 (if not collected in the previous 3 months) and then every 
12 months, and the end of study visit. 
9.6.5 FAMS, Version 4  
The FAMS is a widely accepted, MS-specific, quality of life questionnaire. It has been developed 
and validated in 23 languages, and shows adequate test-retest reliability and internal consistency. 
The FAMS is a self-report multidimensional index comprising a total of 58 items on 7 subscales: 
mobility (7 items); symptoms (7 items); emotional well being (7 items); general contentment 
(7 items); thinking and fatigue (9 items); family/social well being (7 items); and additional 
concerns (14 items, these are not scored). The response period for this measure is the past 7 days. 
Each item (except those for “additional concerns”) is rated on a 5-point scale of 0 to 4. The sum of 
the 44 scored items is the total score, which ranges from 0 to 176, with higher numbers reflecting

a higher quality of life. The total score is the primary criterion by which the effect of treatment on 
quality of life will be assessed; however, subscale totals will also be evaluated. 
FAMS will be collected at D1 (if not collected in the previous 3 months) and then every 
12 months and the end of study visit. 
9.6.6 EuroQoL in 5 dimensions (EQ-5D)  
The EQ-5D is a generic, standardized instrument that provides a simple, descriptive profile and 
a single index value for health status that can be used in the clinical and economic evaluation of 
health care as well as in population health surveys. The EQ-5D comprises 5 dimensions of health: 
mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension 
consists of 3 levels (some, moderate, extreme problems), generating a total of 243 theoretically 
possible health states.  
The index has been validated in 36 languages. The response period is the day of assessment only. 
Assessments will also be made using the EuroQol Visual Analogue Scale (EQ-VAS), which 
captures the self-rating of current health status using a visual "thermometer" with the end points of 
100 (best imaginable health state) at the top and zero (worst imaginable health state) at the 
bottom. 
EQ-5D will be collected at D1 (if not collected in the previous 3 months) and then every 
12 months, and at the end of study visit.

OTHER MEASUREMENTS  
9.7.1 Modified healthcare resource utilization questionnaire (HRUQ)/health related 
productivity questionnaire (HRPQ)  
Patients’ use of healthcare resources, non-medical resources, and informal care as well as their 
work capacity will be assessed at scheduled study visits using a modified questionnaire 
(HRUQ/HRPQ) designed to evaluate the economic impact of MS. 
The questionnaire addresses the following content areas:  
 Employment situation and changes in employment situation due to MS. 
 Admissions and stays in hospital, rehabilitation centers, or nursing homes. 
 Typical MS-related investments (eg, stair and bed lift, ramps, rails) and devices 
(eg, walking aids, wheelchairs). 
 Assistance by community or social services (eg, home nurse, transportation), or help from 
family or friends. 
 Patient reported data regarding employment status. 
Information on resource use is obtained retrospectively, and each type of resource is collected for 
a time period that would minimize recall bias.

Each question requires a binary answer (yes/no) followed by details on the type and quantity of 
the resource. All resources that are expected to be used are prespecified in order to minimize 
errors due to spelling, and hence no open fields or free text (eg, “other”) are permitted. 
Modified HRUQ/HRPQ will be collected at D1 (if the HRUQ questionnaire was administered in 
the previous 3 months, then only questions 1 through 10 of the Modified HRUQ/HRPQ need to be 
completed at baseline, D1). The modified HRUQ/HRPQ will continue to be collected every 
12 months and at the end of study visit. 
9.7.2 Exploratory pharmacogenomic assessment  
For research purposes only and on a voluntary basis, a blood sample will be collected from 
consenting patients for exploratory analysis of genetic variations related to MS disease and/or 
alemtuzumab effects. The results of these analyses will not be provided to the Investigator or the 
patient. DNA sample collection, handling, storage, and analysis will conform to all applicable 
guidance and regulations. Details can be found in Appendix C.

The Study Investigator determines whether patients are eligible for treatment: 
 Patients may receive additional courses of alemtuzumab (see Section 8.1.1) but not sooner 
than 12 months from any previous alemtuzumab treatment course, or  
 Patients may receive other commercial DMTs. 
In case of treatment the Study Investigator must document: 
 Clinical factors for deciding treatment, and/or 
 Imaging factors for deciding the treatment.  
10.1.6 Alemtuzumab treatment  
At any time during the study, the Study Investigator can decide to treat the patient with 
alemtuzumab (provided that the patient has not had alemtuzumab in prior 12 months). 
All the specific recommendations indicated in the IB or in the local approved label (when 
available) should be checked before starting the re-treatment with alemtuzumab.  
The following infusion management procedures must be utilized for each infusion and each 
treatment course to reduce serious reactions temporally associated with LEMTRADA infusion: 
 Pre-infusion: Physicians should obtain a baseline ECG and vital signs (including heart rate 
and blood pressure measurement), screen for pre-existing hemorrhagic, cardiovascular 
(including venous thromboembolism) and cerebrovascular risk factors, screen for lung 
disease, review concomitant medications (eg, antiplatelet agents, anticoagulants), perform 
laboratory tests (complete blood count with differential, serum transaminases, serum 
creatinine, test of thyroid function and urinalysis with microscopy), evaluate infusion-
related risks, and review HCP checklist. Physician should also consider following 
contraindications of alemtuzumab when retreating patient in this study: 
- 
Hypersensitivity to the active substance, or to any of the excipients 
- 
Human Immunodeficiency Virus (HIV) infection 
- 
Severe active infection 
- 
Uncontrolled hypertension 
- 
History of arterial dissection of the cervicocephalic arteries 
- 
History of stroke 
- 
History of angina pectoris or myocardial infarction

- 
Known coagulopathy or on concomitant anti-coagulant therapy 
It is at investigator’s discretion to re-treat or not re-treat patient with alemtuzumab after clinical 
evaluation. 
 During infusion: Continuous/frequent monitoring of heart rate, blood pressure assessment 
(at least hourly) and overall clinical status of the patients including consideration of the 
volume of fluids administered. The following are recommendations in case of clinical 
abnormalities/severe adverse event: 
- 
Interrupt infusion 
- 
Medically evaluate the patient guided by the adverse event profile of LEMTRADA 
prior to considering restarting therapy 
- 
Provide appropriate treatment as needed 
- 
Consider permanently discontinuing the LEMTRADA infusion if the patient shows 
clinical symptoms suggesting development of a serious adverse event associated with 
the infusion (myocardial ischemia, hemorrhagic stroke, cervico-cephalic arterial 
dissection or pulmonary alveolar hemorrhage). 
- 
Implement appropriate measures for patients at risk of venous thromboembolism: 
repeated ambulation during infusion and/or compression stockings. 
 Post-infusion: Observation and education of patients. 
- 
Observation for infusion reactions is recommended for a minimum of 2 hours after 
LEMTRADA infusion.  
- 
Patients with clinical symptoms suggesting development of a serious adverse event 
temporarily associated with the infusion (myocardial ischemia, hemorrhagic stroke, 
cervico-cephalic arterial dissection or pulmonary alveolar hemorrhage) should be 
closely monitored until complete resolution of the symptoms. The observation time 
should be extended as appropriate. 
- 
Patients with persistent blood pressure elevation should be referred to an appropriate 
medical facility for continued monitoring and treatment. 
- 
The patients should be educated on the potential for delayed onset of infusion 
associated reactions and symptoms and signs of cardiovascular or cerebrovascular 
events, and instructed to report symptoms and seek appropriate medical care. 
For monitoring potential risk of autoimmune hepatitis, liver function test must be performed for 
patients who newly initiate retreatment of alemtuzumab, LFT to be performed prior infusion of 
retreatment as baseline, and monthly for 48 months after the last infusion of retreatment of 
alemtuzumab. In addition, LFT may be performed at any time if clinically indicated at 
Investigators’ discretion

If the 48-month period of safety follow-up continues after the study ends, the patient will be 
followed by their physician in a regular healthcare setting, in line with the local approved Risk 
Minimization Plan for alemtuzumab, until the 48-month period is completed.  
10.2 
DEFINITION OF SOURCE DATA  
Source documents are defined as original documents, data, and records. This includes, but is not 
limited to the following: hospital records, clinic and office charts, study-specific source document 
worksheets, MRI, chest X-ray or signed documented X-ray and reports, ECG tracings and reports, 
laboratories reports, medication dispensing records, computer printouts, electronic 
data/information sources and any other documentation regarding the patient.  
10.3 
HANDLING OF PATIENT TREATMENT DISCONTINUATION AND OF PATIENT STUDY 
DISCONTINUATION  
Any IMP discontinuation should be fully documented in the e-CRF. In any case, the patient 
should remain in the study as long as possible. 
10.3.1 Permanent treatment discontinuation with investigational medicinal product(s)  
Permanent treatment discontinuation is any treatment discontinuation associated with the 
definitive decision from the Study Investigator or the patient not to re-expose the patient to the 
IMP at any time. 
10.3.2 List of criteria for permanent treatment discontinuation  
The patients may withdraw from treatment with the IMP if they decide to do so, at any time and 
irrespective of the reason, or this may be the Study Investigator’s decision. All efforts should be 
made to document the reasons for treatment discontinuation and this should be documented in the 
e-CRF. 
10.3.3 Handling of patients after permanent treatment discontinuation  
Patients will be followed-up according to the Study Investigator judgment up to the study 
completion, or up to recovery or stabilization of any AE to be followed-up as specified in this 
protocol, whichever comes last.  
Patients re-treated with alemtuzumab must be followed as described in Section 10.1.6. 
10.3.4 Procedure and consequence for patient withdrawal from study  
The patients may withdraw from the study before study completion if they decide to do so, at any 
time and irrespective of the reason.

If possible, the patients are assessed using the procedure normally planned for the EOS visit 
(Section 10.1.4). 
If a patient has consented to participate in the PGx substudy and withdraws from the TOPAZ 
study, the patient’s PGx sample will be stored for analysis unless the patient specifically indicates 
that it cannot be used following the time of study withdrawal. If the patient withdraws consent of 
sample use, the samples must be destroyed. 
For patients who fail to return to the site, the Study Investigator should make the best effort to 
recontact the patient (eg, contacting patient’s family or private physician, reviewing available 
registries or health care databases), and to determine his/her health status, including at least 
his/her vital status. Attempts to contact such patients must be documented in the patient’s records 
(eg, times and dates of attempted telephone contact, receipt for sending a registered letter). 
At time of withdrawal, any patient who has received an infusion with alemtuzumab less than 
48 months ago should be reminded of the importance to continue to check for symptoms of 
autoimmune conditions and to have monthly laboratory tests performed until the 48-month period 
is completed. 
The SAP will specify how these patients lost to follow-up will be considered. 
10.4 
OBLIGATION OF THE INVESTIGATOR REGARDING SAFETY REPORTING  
10.4.1 Definitions of adverse events  
10.4.1.1 Adverse event  
An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation 
patient administered a pharmaceutical product and which does not necessarily must have a causal 
relationship with this treatment. 
10.4.1.2 Serious adverse event  
A serious adverse event (SAE) is any untoward medical occurrence that at any dose: 
 Results in death, or 
 Is life-threatening, or 
Note: The term “life-threatening” in the definition of “serious” refers to an event in which 
the patient was at risk of death at the time of the event; it does not refer to an event which 
hypothetically might have caused death if it were more severe. 
 Requires inpatient hospitalization or prolongation of existing hospitalization, or 
 Results in persistent or significant disability/incapacity, or 
 Is a congenital anomaly/birth defect

Version number: 1 
Property of the Sanofi Group - strictly confidential 
Page 50 
 Is a medically important event 
Medical and scientific judgment should be exercised in deciding whether expedited reporting is 
appropriate in other situations, such as important medical events that may not be immediately life-
threatening or result in death or hospitalization but may jeopardize the patient or may require 
medical or surgical intervention (ie, specific measures or corrective treatment) to prevent one of 
the other outcomes listed in the definition above. 
Note: The following list of medically important events is intended to serve as a guideline for 
determining which condition must be considered as a medically important event. The list is not 
intended to be exhaustive: 
 Intensive treatment in an emergency room or at home for: 
- 
Allergic bronchospasm.  
- 
Blood dyscrasias (ie, agranulocytosis, aplastic anemia, bone marrow aplasia, 
myelodysplasia, pancytopenia, etc).  
- 
Convulsions (seizures, epilepsy, epileptic fit, absence, etc). 
 Development of drug dependence or drug abuse. 
 ALT >3 x ULN + total bilirubin >2 x ULN or asymptomatic ALT increase >10 x ULN. 
 Suicide attempt or any event suggestive of suicidality. 
 Syncope, loss of consciousness (except if documented as a consequence of blood sampling). 
 Bullous cutaneous eruptions. 
 Cancers diagnosed during the study or aggravated during the study. 
 Chronic neurodegenerative diseases (newly diagnosed) or aggravated during the study 
(only if judged unusual/significant by the Study Investigators in studies assessing 
specifically the effect of a study drug on these diseases). 
 Suspected transmission of an infectious agent: if any suspected transmission of 
an infectious agent via a medicinal product (eg, product contamination).  
10.4.1.3 Adverse event of special interest  
An adverse event of special interest (AESI) is an AE (serious or non-serious) of scientific and 
medical concern specific to the Sponsor’s product or program, for which ongoing monitoring and 
immediate notification by the Study Investigator to the Sponsor is required. Such events may 
require further investigation in order to characterize and understand them. Adverse events of 
special interest may be added or removed during a study by protocol amendment. 
AESI will be reported to the Sponsor in the same timeframe as SAEs, ie, within 24 hours, as 
detailed in Section 10.4.4.  
The following AE will be considered as AESI: 
 Hypersensitivity or anaphylaxis

as an SAE only if it fulfills one of the seriousness criteria (see Section 10.4.1.2). 
- 
Follow-up of the pregnancy in a woman participant is mandatory until the outcome has 
been determined. 
 Symptomatic overdose (serious or non-serious) with IMP. 
- 
An overdose (accidental or intentional) with the IMP is an event suspected by the 
Study Investigator or spontaneously notified by the patient and defined as increase of 
at least 30% of the dose to be administered in the specified duration or if the dose is 
administered in less than half the recommended duration of administration. 
Of note, asymptomatic overdose must be reported as a standard AE. 
 Increase in alanine transaminase (ALT) (see the “Increase in ALT” flow diagram in 
Appendix B of the protocol). 
 Other product specific AESIs: 
- 
Autoimmune mediated conditions including, but not limited to:

10.4.1.4 Events not to be considered as AEs/SAEs  
Medical conditions present at the initial trial visit (Visit1) that do not worsen in severity or 
frequency during the trial are defined as baseline medical conditions, and are not to be considered 
AEs. However, baseline medical conditions other than the disease under trial that worsen in 
severity or frequency during the trial should be recorded and reported as AEs. 
In this protocol, symptoms and signs of exacerbation or worsening of the disease under trial will 
usually be captured in the context of efficacy assessment, and recorded on the relapse module of 
the eCRF. Therefore, symptoms, relapses or worsening of MS will not be considered as AEs nor 
captured on the AE module of the eCRF unless this event is considered possibly or probably 
related to the IMP (ie, worsening is not consistent with the anticipated natural progression of the 
disease) and/or the MS relapse meets the criteria for a serious AE (eg, requires hospitalization). 
10.4.2 General guidelines for reporting adverse events  
 All AEs, regardless of seriousness or relationship to IMP, spanning from the signature of 
the informed consent form until the end of the study as defined by the protocol for that 
patient, are to be recorded on the corresponding page(s) or screen(s) of the CRF. At Visit 1 
the ongoing AEs started during the Extension Study CAMMS03409, or occurred between 
the final visit of the CAMMS03409 study and Visit 1, are also to be recorded. 
 Whenever possible, diagnosis or single syndrome should be reported instead of symptoms. 
The Study Investigator should specify the date of onset, intensity, action taken with 
respect to IMP, corrective treatment/therapy given, additional investigations performed, 
outcome, and his/her opinion as to whether there is a reasonable possibility that the AE 
was caused by the IMP or by the study procedure(s).  
 The Study Investigator should take appropriate measures to follow all AEs until clinical 
recovery is complete and laboratory results have returned to normal, or until progression 
has been stabilized, or until death, in order to ensure the safety of the patients. This may 
imply that observations will continue beyond the last planned visit per protocol, and that 
additional investigations may be requested by the monitoring team up to as noticed by the 
Sponsor.  
 When treatment is prematurely discontinued, the patient’s observations will continue until 
the end of the study as defined by the protocol for that patient. 
 Laboratory, vital signs or ECG abnormalities are to be recorded as AEs only if:  
- 
Symptomatic and/or  
- 
Requiring either corrective treatment or consultation, and/or  
- 
Leading to IMP discontinuation or modification of dosing, and/or  
- 
Fulfilling a seriousness criterion, and/or  
- 
Defined as an AESI. 
 AEs/AESIs that are ongoing at the end of the patient’s participation in CAMMS03409 
should be followed during the LPS13649 study.

10.4.3 Instructions for reporting serious adverse events  
In the case of occurrence of an SAE, the Study Investigator must immediately: 
 ENTER (within 24 hours) the information related to the SAE in the appropriate screens of 
the e-CRF; the system will automatically send a notification to the monitoring team after 
approval of the Study Investigator within the e-CRF or after a standard delay. 
 SEND (preferably by fax or e-mail) a photocopy of all examinations carried out and the 
dates on which these examinations were performed, to the representative of the monitoring 
team whose name, fax number, and email address appear on the clinical trial protocol. 
Care should be taken to ensure that the patient's identity is protected and the patient’s 
identifiers in the clinical trial are properly mentioned on any copy of a source document 
provided to the Sponsor. For laboratory results, include the laboratory normal ranges. 
 All further data updates should be recorded in the e-CRF as appropriate, and further 
documentation as well as additional information (for laboratory data, concomitant 
medications, patient status, etc) should be sent (by fax or e-mail) to the monitoring team 
within 24 hours of knowledge of the SAE. In addition, every effort should be made to 
further document any SAE that is fatal or life threatening within a week (7 days) of the 
initial notification. 
 A back-up plan (using a paper CRF process) is available and should be used when the 
e-CRF system does not work. 
Any SAE brought to the attention of the Study Investigator at any time after the end of the study 
for the patient and considered by him/her to be caused by the IMP with a reasonable possibility, 
should be reported to the monitoring team. 
10.4.4 Guidelines for reporting adverse events of special interest  
For AESIs, the Sponsor must be informed immediately (ie, within 24 hours), as per SAE 
notification guidelines described in Section 10.4.3, even if not fulfilling a seriousness criterion, 
using the corresponding screens in the e-CRF.

prior CAMMS03409 extension study.  
11.2 
DISPOSITION OF PATIENTS  
All CAMMS03409 patients that fulfill the inclusion/exclusion criteria are eligible for enrollment. 
A detailed description of patient disposition will be provided. It will include: 
 A summary of data on patient discontinuation 
 A summary of data on overall Screening and qualification status of all patients 
 An account of all identified protocol deviations 
In addition, the treatment regimen for all patients will be summarized. This includes summarizing 
the percentage of patients receiving alemtuzumab on an as-needed basis, and the time to 
treatment. 
11.3 
ANALYSIS POPULATIONS  
11.3.1 Safety population  
All patients who have signed the ICF will be included in the safety population. 
11.3.2 Efficacy populations  
The population on which efficacy analyses will be performed consists of all enrolled patients who 
have received study drug in CAMMS223, CAMMS323, CAMMS324 or CAMMS03409. 
11.4 
STATISTICAL METHODS  
All data collected in this study will be reported using summary tables, figures, and patient data 
listings. Summary statistics will be computed and displayed by treatment group (assigned in the

11.4.1 Analyses of efficacy endpoints  
The long-term effects of alemtuzumab in patients who received alemtuzumab prior to the 
extension Study CAMMS03409 (eg, in Studies CAMMS223, CAMMS323, or CAMMS324) will 
be examined by summarizing the efficacy endpoints from prior study baseline through the end of 
study participation for each patient. Efficacy will be evaluated using proportion of patients relapse 
free, relapse rate, ARR, change over time in EDSS, MRI, and QoL measures, starting at baseline 
of the earlier studies.  
The same efficacy evaluations will be made for patients who received SC IFNB-1a prior to the 
extension Study CAMMS03409 and who subsequently received alemtuzumab in the extension 
study. For these patients, efficacy will be assessed from the time of their first study treatment in 
CAMMS323 and CAMMS324 or from the time of randomization in CAMMS223. 
The number of patients with a relapse event, the total number of relapses, and the annualized 
relapse rate over the years of follow-up will be produced. The annualized relapse rate will be 
estimated using a negative binomial model with robust variance estimation. The model will be 
stratified by clinical study.  
A detailed description of the methods utilized to analyze each of the efficacy endpoints will be 
provided in the SAP.  
11.4.2 Analyses of safety data  
All patients in the study will be evaluated for safety. A summary of safety will be evaluated based 
on incidence, duration, grade/intensity, seriousness, and relationship of AEs to study drugs, and 
on changes in physical examination, vital signs, and clinical laboratory results, particularly 
hematological parameters and biochemical, immunological, and clinical indications of ITP, 
infection, and thyroid dysfunction observed in this study. Deaths and other SAEs will also be 
evaluated. Particular attention will be paid to the development of autoimmune disorders including 
the incidence of ITP, autoimmune thyroid disorders and anti-GBM disease. Further elaboration of 
statistical issues will be provided in the SAP. 
11.4.3 Analyses of patient reported outcomes (health-related quality of life/health 
economics variables  
Change over time in self-reported quality of life (QoL) as assessed by the Medical Outcome Study 
(MOS) 36-Item Short-Form Health Survey (SF-36) Version 2, the Functional Assessment of 
Multiple Sclerosis (FAMS), and the EuroQoL in 5 Dimensions (EQ-5D), will be analyzed relative 
to the baseline obtained at the start of the original studies. 
Change over time in modified HRUQ/HRPQ will also be analyzed.

and the need to commit to periodic monitoring for 48 months after the last 
treatment). 
6 weeks prior to 
treatment 
(if needed) 
Vaccinations 
It is recommended that patients have completed local immunization 
requirements. 
Consider VZV vaccination of antibody negative patients before initiating 
a course of alemtuzumab treatment. 
Immediately prior 
to treatment 
Pre-treatment 
Immediately prior to alemtuzumab pre-treat with corticosteroids on each of 
the first 3 days of any treatment course. 
Pre-treatment for IARs 
Pretreatment with antihistamines and/or antipyretics prior to alemtuzumab 
administration may also be considered. 
Oral prophylaxis for herpes 
Administer 200 mg aciclovir (or equivalent) twice a day from first day of 
treatment and continuing for a minimum of 1 month following treatment. 
General health 
Consider delaying initiation of alemtuzumab administration in patients with 
active infection until the infection is fully controlled 
Pregnancy & contraception 
Ensure women of child bearing potential use effective contraceptive 
measures when receiving a course of treatment with alemtuzumab and for 
4 months following the course of treatment. 
If patient is pregnant, administer only if the potential benefit justifies the 
potential risk to the fetus.

a Note: For sites using homecare nurses service, or where microscopy is not routinely done if urine dipstick analysis is negative, the following 
procedure will be implemented: Homecare nurses/investigator site staff will perform a urine dipstick which will secure the detection of any 
potential haematuria and/or proteinuria. If urine dipstick is positive, the investigator would need to ask the patient to come to the site to have 
microscopy performed at the local lab. At any time, as per investigator criteria, according to the patient’s status, the patient can be asked to 
have a microscopy at the local lab to confirm any potential diagnosis.

Exploratory pharmacogenomics assessment substudy  
Background information 
The autoimmunity adverse events associated with LEMTRADA are identified potential risks and 
pose a potential barrier to a greater use of the product, including autoimmune thyroid disorders 
(36%), immune thrombocytopenia (ITP; 2%), and nephropathies (0.3%). If biomarkers for 
autoimmunity were known, more patients could potentially benefit from LEMTRADA treatment. 
A team effort has been under way to discover a panel of biomarkers that could predict which 
patients are at risk of developing autoimmunity events. Blood samples collected from 
LEMTRADA-treated MS patients within clinical studies were preserved for biomarker discovery. 
Genomics and proteomics profiling were conducted on a cohort of LEMTRADA-treated MS 
patients, including patients who developed treatment-emergent autoimmune disorders and patients 
who, to date, have not developed such disorders. The search for the associated markers was 
focused on single nucleotide polymorphism (SNP), human leukocyte antigen (HLA)-allele, 
HLA-amino acid polymorphism, serum cell-free microRNA, serum protein, and serum 
autoantibody. 
Correlative analysis of this biomarker data with the development of autoimmune conditions 
indicated no robust signals for protein biomarkers. Interestingly, we identified candidate SNPs 
that are potentially associated with the development of ITP with this preliminary discovery data 
set. Although potential predictors have been identified, more samples are needed to validate this 
data. Samples from the TOPAZ study together with samples from patients from previous clinical 
trials (CAMMS03409, CAMMS223, CAMMS323 and CAMMS324) and from post-marketing 
patients will provide a large enough cohort to validate the to validate the preliminary findings 
(and potentially efficacy/non-responders). Samples from patients who have not yet developed any 
autoimmune conditions would be used as controls.  
The goal of this exploratory substudy is to obtain additional data to identify a biomarker for 
autoimmune events so that LEMTRADA can be safely administered to patients who need the 
treatment. 
Objectives 
The following high level objectives are proposed:  
 Develop biomarkers predictive of autoimmune conditions including thyroid and ITP. This 
will include collection of samples from patients who have not yet developed any 
autoimmune conditions. These samples would be used as controls.  
 Explore efficacy and safety markers through data analysis 
 Explore genetic variation related to MS disease manifestation through data analysis

Rationale  
TOPAZ patients have >7 years post LEMTRADA treatment experience. The intent is to collect 
blood samples from approximately 300 consenting patients for the purpose of exploratory 
analyses of genetic variations related to MS disease and/or alemtuzumab effects.  
Investigational plan 
For research purposes only and for those patients who signed the optional pharmacogenomic 
informed consent form, a blood sample will be collected at the study visit for exploratory analysis 
of genetic variations related to MS disease and/or alemtuzumab effects as specified in the study 
flow chart, and this sample will be stored.  
Samples will be processed for DNA isolation and for genetics analysis. Genomic data generated 
from these samples (including samples collected from TOPAZ patients with no autoimmunity) 
will be used to validate a predictive marker panel from discovery cohort analysis. DNA sample 
collection, handling, storage, and analysis will conform to all applicable national guidance and 
regulations as follows.  
This blood sample will be transferred to a site that will, on behalf of Sanofi, store it until the time 
of analysis.  
The blood sample, and the DNA that is extracted from it, will be assigned a second number, 
a Genetic ID (deidentification code) that is different from the Subject ID. This “double coding” is 
performed to separate a subject’s medical information and DNA data. 
The clinical study data (coded by Subject ID) will be stored in the clinical data management 
system (CDMS), which is a distinct database in a separate environment from the database 
containing the pharmacogenetic data (coded by Genetic ID). The key linking Subject ID and 
Genetic ID will be maintained by a third party, under appropriate access control. The matching of 
clinical data and pharmacogenetic data, for the purpose of data analysis, will be possible only by 
using this key, which will be under strict access control. All data will be reported only in coded 
form in order to maintain confidentiality. 
The samples will be stored at a secure site specialized for such investigations under the 
responsibility of the Sponsor for up to 15 years after completion of the final study report of the 
LPS13649 study. All data is anonymized. If the patient withdraws consent to participate in the 
PGx substudy, the patient’s PGx sample will be destroyed. 
Patient selection criteria 
Sample size will be based on elective participation of approximately 300 patients who are enrolled 
into the TOPAZ study. 
Pharmacogenomic sampling 
PGx samples will be collected from consenting TOPAZ patients that have not previously provided 
a PGx sample in parent studies.

Three aliquots at 2.5 mL each of whole blood (from each patient) will be drawn. 
Detailed information about samples storage will be provided by the sponsor in the laboratory 
manual.  
PGx blood samples will be maintained until the end of this study, when the conclusion is 
finalized, or 15 years, or as approved locally 
Planned sample analysis 
These samples will be used for exploratory analysis of genetic variations predictive of 
autoimmune conditions related to MS and or the effects of alemtuzumab and or MS disease 
manifestation using genetic analysis platform technologies

Substudy 
Add the following text: 
A pharmacogenomics (PGx) substudy will be conducted 
for exploratory analysis of genetic variations predictive of 
autoimmune conditions, including thyroid and immune 
thrombocytopenia (ITP), related to MS disease and/or the 
effects of alemtuzumab. For research purposes only and 
on a voluntary basis, a blood sample will be proposed to 
approximately 300 ongoing patients in the TOPAZ study 
who have not provided a PGx sample in the previous 
studies (CAMMS03409, CAMMS223, CAMMS323 and 
CAMMS324). A blood sample will be collected from 
consenting patients.  
Objectives of the substudy are as follows:  
 
To develop biomarkers predictive of 
autoimmune conditions including thyroid 
disorders and immune thrombocytopenia. This 
will include collection of samples from patients 
who have not yet developed any auto immune 
conditions; these samples would be used as 
controls.  
 
To explore efficacy and safety markers through 
data analysis. 
 
To explore genetic variation related to MS 
disease manifestation through data analysis. 
Sample collection, handling, storage, and analysis will 
conform to all applicable national guidance and 
regulations. Details of the PGx sub-study are presented in

is negative, the following procedure will be implemented: 
Homecare nurses/investigator site staff will perform a 
urine dipstick which will secure the detection of any 
potential haematuria and/or proteinuria. If urine dipstick is 
positive, the investigator would need to ask the patient to 
come to the site to have microscopy performed at the 
local lab. At any time, as per investigator criteria, 
according to the patient’s status, the patient can be asked 
to have a microscopy at the local lab to confirm any 
potential diagnosis.

screening performed approximately 1 year after the last 
infusion of alemtuzumab, and then every 12 months until 
48 months safety FU is completed. 
For women, an HPV screening must be performed as 
follows: 
For women patients re-treated with alemtuzumab during 
the TOPAZ study, an HPV screening should be 
performed prior to re-treatment (if not done in the 
previous 12 months) and then every 12 months until 48 
months safety FU is completed.

4 Introduction and rationale 
Add the following text: 
Of note, Listeriosis/Listeria meningitis has been reported 
in LEMTRADA treated patients, generally within one 
month of LEMTRADA infusion. To reduce the risk of 
infection, patients receiving LEMTRADA should avoid 
ingestion of uncooked or undercooked meats, soft 
cheeses, and unpasteurized dairy products two weeks 
prior to, during, and for at least 1 month after LEMTRADA 
infusion.

3. Amended Clinical Trial Protocol 02 (24-Jul-2019) 
This amended protocol is considered to be substantial based on the criteria set forth in 
Article 10(a) of Directive 2001/20/EC of the European Parliament and the Council of the 
European Union because it significantly impacts the safety or physical/mental integrity of 
participants. 
Overall Rationale for the Amendment 
This amended protocol is written to provide information about new safety concerns that have been 
identified from post-marketing use with alemtuzumab. This includes reports of autoimmune 
hepatitis and hemophagocytic lymphohistiocytosis (HLH), as well as temporally associated 
serious cardiovascular reactions. Substantial changes in this amended protocol are related to 
providing information on the new safety concerns and measures to minimize the risks of patients 
included in clinical trials. 
The Sponsor has conducted a comprehensive review of safety data and identified two areas where 
risk mitigation measures will be implemented in this study; 1) Infusion-related risks, specifically 
hemorrhagic risks, and 2) Autoimmune hepatitis where additional laboratory tests may be of 
value.

Brief Rationale 
within three days of alemtuzumab administration, 
with most cases occurring within one day. Cases of 
pulmonary alveolar hemorrhage have been 
reported with onset within 48 hours of 
alemtuzumab infusion. Long term auto immune 
risks, such as cases of Hemophagocytic 
lymphohistiocytosis (HLH) and autoimmune 
hepatitis causing clinically significant liver injury, 
including acute liver failure requiring transplant, has 
been reported. To minimize the risk of these 
serious adverse events, recommendations are 
provided for infusion related management and long 
term safety monitoring for patients receiving 
re-treatment of alemtuzumab during the course of 
the trial  
 
Pre infusion: assess overall health status 
and risk factors; baseline BP/HR, 
bleeding risk, platelets count. Baseline 
liver function test. 
 
During infusion: continuous or hourly 
monitoring BP/HR; intermittently 
ambulation, compressive stocking. 
 
Post infusion: inform/remind patient any 
abnormal clinical sign/symptoms related 
to infusion.  
 
Periodic liver function test. 
9.5.2.2 Patients exposed to 
alemtuzumab during this 
study 
Liver function test must be performed prior 
retreatment with alemtuzumab and repeated every 
3 months for  
48 months. … LFT may be performed at any time if 
clinically indicated at Investigators’ discretion. 
Monitoring potential autoimmune hepatitis 
10.1.6 Alemtuzumab 
treatment 
Add the following text: 
The following infusion management procedures 
must be utilized for each infusion and each 
treatment course: 
 
Pre-infusion: Physicians should identify 
potential cardiovascular and 
cerebrovascular risk factors (eg, screen 
for pre-existing hemorrhagic, 
cardiovascular (including venous 
thromboembolism) and cerebrovascular 
risk factors, lung disease, concomitant 
medications (eg, antiplatelet agents, 
anticoagulants) and review of infusion-
related risks, and HCP checklist.  
 
During infusion: in addition to 
continuous/frequent monitoring of heart 
rate, blood pressure assessment (at least 
hourly) and overall clinical status of the

Brief Rationale 
patients including consideration of the 
volume of fluids administered. The 
following are recommendations in case of 
clinical abnormities: 
- 
Adjust or interrupt infusion, as 
necessary; if clinically significant 
changes in vital functions are 
observed, additional monitoring, 
including ECG, should be 
considered. 
- 
When re-starting, consider a slower 
rate of infusion. 
- 
Appropriate management of blood 
pressure during infusion, including 
pharmacotherapy as necessary. 
- 
Implement appropriate measures for 
patients at risk of venous 
thromboembolism: repeated 
ambulation during infusion and/or 
compression stockings. 
 
Post-infusion: Observation and education 
of patients. 
- 
Minimum until 2 hours after infusion 
has ended or longer until 
stabilization. 
- 
Patients with persistent blood 
pressure elevation should be 
referred to an appropriate medical 
facility for continued monitoring and 
treatment. 
- 
Education on delayed infusion 
associated reactions and symptoms 
and signs of cardiovascular or 
cerebrovascular events. 
- 
Instructions to patients to seek 
urgent medical care if there are 
signs and symptoms of 
cardiovascular, pulmonary or 
cerebrovascular events. 
For monitoring potential risk of autoimmune 
hepatitis, liver function test must be performed for 
patients who newly initiate retreatment of 
alemtuzumab, LFT to be performed prior infusion of 
retreatment as baseline, every 3 months for 
48 months after the last infusion of retreatment of 
alemtuzumab. In addition, LFT may be performed 
at any time if clinically indicated at Investigators’ 
discretion.
