Purpose and
rationale
The design of this study addresses the primary objective of establishing 
efficacy in this indicationfor both children and adults. The randomized, 
controlled design allows comparison of LFG316 plus standard of care 
(excluding prohibited treatment) against Standard of Care (SoC)only.
Thestudy will allow inclusion of patients≥2 years oldafter safety of LFG316 
is demonstrated during interim analysis 1 (IA1)with 5 patients ≥12 years old 
treated with LFG316 for 4weeks. There are no pediatric data generated so 
far for LFG316;however eculizumab was administered to pediatric TAM 
patients. The nonclinical data obtained with LFG316 and the clinical data 
obtained with eculizumab supports administration of LFG316 to children 
≥2years old. The option for patients not responding in either arm to switch to 
the alternative arm when certain conditions are met allows all patients the 
opportunity to receive LFG316 treatment in this very rare indication with high 
unmet medical need and also ensures that patients who fail to improve on 
LFG316 are not prevented from receiving the SoC treatment. This element of 
the design does not affect the assessment of efficacy since patients who do 
switch treatments will be considered to be treatment failures in the 
comparison of the randomized treatment groups. An open-label design is 
used instead of a blinded placebo since it is not feasible to blind the 
treatments used in the SoC arm.
Primary Objective(s)
To assess the hematological response rate in patients with TAM receiving 
LFG316 plus standard of care (excluding prohibited treatment) against 
Standard of Care (SoC) only.
Secondary 
Objectives

To assess the safety and tolerability of LFG316 in patients with TAM 

To describe the pharmacokinetics of total LFG316

To evaluate non-relapse mortality in TAM patients treated with 
LFG316 as compared to patients on SoC

To assess complete response rate at 17 weeks in TAM patients 
treated with LFG316 compared to patients receiving standard of care

possible or will result in an unfavorable risk benefit ratio as judged 
by the investigator, vaccination can be postponed until deemed likely 
to be effective. 
Patients <18 years old should receive vaccination for the prevention 
of S. pneumoniae and H. influenzae type b prior to LFG316 
administration.In case vaccination is not possible or will result in an

Exclusion criteria
Key exclusion criteria

Use of other investigational drugs at the time of enrollment, or within 
5 half-lives of enrollment, or until the expected PD effect has returned 
to baseline, whichever is longer; or even longer if required by local 
regulations.Concomitant investigational treatment, including 
treatment in the context of a clinical trial with marketed drugs (off-
label) may be acceptable but requires approval by the sponsor on the 
case by case basis.

Data analysis
A patient is considered to be a hematological responder at 17 weeks if both 
of the following criteria are met:
1. Schistocytes <2/microscopic high power field (HPF).
2.Transfusion independent (no need for TAM-related transfusions (platelets 
and erythrocytes)
Patients who discontinue the randomized treatment before 16 weeks due to 
lack of efficacy (whether according to the protocol-defined rules allowing a 
switch to the alternative treatment arm, or not) will be considered non-
responders in this analysis. Data from these patients collected after switching 
treatment will be considered as supportive data but will not be included in the 
primary analysis.
The primary analysis will compare all randomized patients according to the 
treatment they were assigned. A supportive analysis will compare patients 
according to the degree of complement blockade achieved.
The analysis of hematological response at 17 weeks will present posterior 
probabilities of meeting the outcome criteria as defined above. The prior 
distribution for the response rate in each group will be assumed to be a 
neutral non-informative Beta (1/3, 1/3) distribution.

The effect of presence/absence of proteinuria at baseline (a key prognostic 
factor of response) on the response rates in eachgroup will be investigated. 
The effects of other covariates such as donor type and conditioning regimen 
will also be investigated.
Secondary variables supporting the secondary objectives will include:
Complete response, defined as hematologicalresponse and no proteinuria as 
determined by proteinuria<30mg/dL and eGFRdoubled or not less than 
0.85x lower limit of normal

Non-relapse mortality

Overall survival

Complete response will be analyzed in the same way as the primary 
variable of hematological response. Non-relapse mortality and overall 
survival will be summarized using time to even methods.
Further details on the analysis and presentation of these variables will be 
provided in the RAP.
All other data will be summarized and listed by treatment as appropriate.

Introduction
1.1
Background
Transplant Associated Microangiopathy(TAM;or transplant-associated TA-TAM) is a 
complication of allogeneic hematopoietic stem cell transplantation (HSCT). TAM is a 
secondary microangiopathy associated with total body irradiation, high dose chemotherapy, 
viral reactivation and use of calcineurin inhibitors and rapamycin. TAM does not fall into 
either major category of thromboticmicroangiopathies (TMA), i.e. atypical hemolytic uremic 
syndrome (aHUS) or thrombotic thrombocytopenic purpura (TTP) (Chapin et al 2014). 
Theexact mechanism of TAM is poorly understood, but is thought to involve initial 
complement activation and C5-dependent effector mechanisms, which also lead to 
immunoglobulin consumption. The trigger appears to be endothelial cell damage, leading to a 
prothrombotic state in the microvasculature.  TAM can gives rise to renal, gastrointestinal and 
neurological dysfunction depending on the area of the vascular bed involved. TAM is 
associated with high morbidity and mortality, with some estimates of associated mortality as 
high as 80% (Chapin et al 2014). Complement involvement is suggested by recent clinical 
data with the C5 targeted antibody eculizumab. Preliminary data indicates that 4 of 6 subjects 
undergoing HSCT procedures had a beneficial responseafter eculizumab administration
(Jodele et al 2014a). In total as of this writing (March 2015) 25 patients have been reported to 
have undergone eculizumab treatment withmixed results. Positive response in the published 
cases seems to be associated with low body weight, high dose per weight and absence of 
severe acute graft versus host disease. 
LFG316 is a fully human monoclonal IgG antibody that targets complement factor 5 (C5). 
There is experience with the use of LFG316 in intravenous and intravitreal formulations in the 
clinic (an intravitreal formulation of LFG316 is currently being evaluated for the treatment of
age-related macular degeneration (AMD)). However as an intravenous formulation of
LFG316 will be usedin TAM, the clinical results with intravenous use are considered most 
relevant and are presented below.
LFG316 will be dosed on a per weight basis for the TAM indication. Therefore, LFG316dose 
will be individualized which is expected to result in superior efficacy, especially in dose 
sensitive indications.
This studyis planned in severe TAM which Novartis proposes to define based on the presence 
of both diagnostic and high risk criteria (please refer toSection 4.1).
Because a highunmet medical need in TAM is in children(Jodele et al 2014b), the study will

Investigational plan
3.1
Study design
This is a randomized, SoC-controlled, open-label, multi-center study in patientswith TAM 
after hematopoieticprecursor cell transplantation(HPCT)from a related or unrelated donor 
for malignant and nonmalignant disease after myeloablative or non-myeloablative 
conditioning. 
The study will consistof up to 28 days of screening period, 16 weeks treatment period that 
can be extended to maximum of total45 weeks(in case ofongoing symptoms of TAM ),
36weeks follow up, and end of study visit (EOS) at week52 (Figure 3-1).Duration of follow 
up will depend on duration of treatment. Patients who are treated for more than 41 weeks will 
proceed directly to EOS visit.
Approximately 40 patients will be randomizedto receive standard of care treatment (SoC) 
(including but not limited to immunosuppressive drugs, such as rituximab, and 
plasmapheresis) or LFG316 plus SoC(excluding plasmapheresis and prohibited treatment as 
per Table 5-1). Patients will be included in the study if they have diagnosis of TAM and poor 
prognostic markers as specified in Section 4. 
 
 
Patients randomizedto LFG316 will receive 
 onstudydays1, 8,and 15,
followed byweekly doses of 
 for remainingtreatment duration of total 16weeks.  
 
 
Patients showing worseningdisease(definition below)after two weeks of treatment (day15)
or lateruntil visit at week 3,will be considered failures and can be switched to receive the 
alternative treatment (SoC or LFG316).

and/or increase inerythrocyte or platelettransfusion need (increase of 50% or more  in 
number of transfusions during 2 weeks prior to study visit as compared to  number of 
transfusions needed two weeks before treatment initiation),
and/or  increasing proteinuria (+50% or more as compared to baseline)
Patients showing no response(definition below) between visit at week 4 (day 29)andvisit at 
week 16will be considered to be treatment failures and can be switched to the other treatment 
arm. Switching the treatment can occur immediately after data is available.
no decrease in schistocyte count ( as compared to baseline) 
and/or continuederythrocyte or platelettransfusion need (less than 25% improvement  
in number of transfusions during 2 weeks prior to study visit as compared to number 
of transfusions needed twoweeks before treatment initiation)

Patients can only switchstudy treatment arms once.
Unscheduled visits will be allowedto check for above parametersin case the data is not 
available at day 15 or day 29 or at later scheduled visitsand there is suspicion of insufficient 
improvement. Patients who switch from SoC to LFG316 will need to repeat the visit and 
dosing schedule starting from visit 3 when first dose of study medication is administered. 
Patients who change from LFG316 to SoC will continue with their visits as per 
Assessmentschedule. 
Patients who have ongoing symptoms of TAM may be continued on LFG316 for maximum of 
total 45 weeks if deemedsafe by the investigator. Decision on continuation of the dose after
week 16 will be discussed and agreed with the sponsor on a case by case basis. 
All patients will receive prophylactic doses of antibiotics active against N. meningitidisduring 
the entireLFG316treatment periodand at least8 weeks after the last treatmentwith LFG316. 
The choice of antibiotic medication will be as per hospital standard. 
The primary endpoint assessment will be done at week 17 (i.e. 1 week after last dose on week 16).

Rationale forstudy design
The design of this study addresses the primary objective of establishing efficacy in this 
indication. The randomized, controlled,stratified design allows comparison of LFG316 
against SoC.
 
 
There are no pediatric data generated so far for LFG316;however eculizumab was 
administered to pediatric TAM patients. The published case reports of C5a blockade in 
TAMcomprise 25 patients of whom 16 were pediatric (age range 1.2-11years) 
(deFontebruneetal2015, Jodeleetal2014a, Jodeleetal2014c, Okano et al 2014). 
Nounexpected safety events related to C5 blockade were reported. No case ofinvasive

meningitis, a known risk of C5a blockade, was reported in TAM so far. Prophylactic 
antibiotics active against N. menigitidis will be usedtomitigate the risk of the infection.
Based on published information in the Eudract database, studies witheculizumab are ongoing 
in pediatric subjects (2-17 years of age) with PNH and in pediatric subjects aged 1month and 
upwards with atypical hemolytic uremic syndrome (AHUS).
The nonclinical data obtained with LFG316 and the clinical data obtained with eculizumab
supports administration ofLFG316 to children≥12 years old, followed by children≥2 years 
old.Given theavailable data andhigh risk of the disease with standard of care treatment, 
excluding children from this treatment does not seem to bejustifiable. 
The option for patients not responding in either arm to switch to the alternative arm when 
certain conditions are metallows all patients the opportunity to receive LFG316 treatment in 
this very rare indication with high unmet medical need and also ensuresthat patients who fail 
to improve on LFG316 are not prevented from receiving the SoC treatment. This element of 
the design does not affect the primary assessment of efficacy since patients who do switch 
treatments will be considered to be treatment failures in the comparison of the randomized 
treatment groups. An open-label design is used since it is not feasible to blind the treatments 
used in the SoC arm.

3.4
Rationale for choice of comparator
In severe TAM there is no unified established standard of care treatment. As such, severe 
TAM is distinct from non-severe TAM where discontinuation of calcineurin inhibitors (CNIs) 
is the standard of care (as here CNI treatment is thought to be the cause of the disease 
(Kimetal2015)). Due to the relative rarityand severity of the disease,physicians often apply 
multiple (off-label) treatments in parallel. Among the most commonly used treatments are 
steroids, cyclophosphamide, rituximab anddefibrotide. Off-label use of eculizumab is 
reported increasingly (Kim et al 2015). Although plasmapheresis is widely viewed as being 
futile in this indication it is still used by some centers as a last line measure in patients who 
have failed to respond to other treatments. LFG316 will be compared with site specific SoC, 
since TAM is a potentially fatal disease and placebo treatment is not considered ethically 
acceptable.
Patients in LFG316 treatmentgroup will not be allowed plasmapheresis because of drug 
wash-out. All other SoC treatments that do not interfere with the mode of action (MoA)of 
LFG316(e.g. corticosteroids, rituximab) are allowed in all patients included in the study. 
Direct signaling, complement dependent cellular cytotoxicity (CDC) and antibody dependent 
cellular cytotoxicity all appear to play a role in rituximab efficacy (Weiner 2010). 
SinceLFG316 will suppress free C5 concentrations and hence is likely to reduce CDC, it is 
possible that the administration of LFG316 may negate some of the mechanisms of efficacy of 
rituximab.However, the magnitude of this effect is unknownandrituximab remains an
allowed concomitant medication.Drugs that have the same mode of action as LFG316 
(eculizumab)are prohibited(please refer to Table 5-1for full list of prohibited treatments).

Risks and benefits
TAM is a life-threatening complication after allogeneic hematopoietic stem cell 
transplantation (HSCT).In surviving patients TAM may be associated with morbidities such 
as hypertension, chronic kidney disease, pulmonary hypertension gastrointestinal and central 
nervous system disease.Currently there is no approved and effective therapy for TAM. 
Classical treatment regimens consist of supportive measures that include withdrawal of 
triggering agents such as calcineurin inhibitors, treatment of co-existing conditions such as 
infections that may promote TAM and management of hypertension. Eculizumab was used 
successfully in a limited number ofpatients (Jodele et al 2014a). 
 
 
The prevalenceof TAM post-HSCThas recently been reported to be 39% in a prospective 
cohort study in children (Jodele et al 2014b). The 1-year non relapse mortality was43.6% in 
subjects with TAM and 7.8% inHSCT subjects without TAM(p<0.0001).A retrospective 
analysis of 539 adult and pediatric patients reported a cumulative incidence of TAM at five 
years of 14% with a mortality of 50%. Adults and children were both similarly affected 
(Uderzo et al 2006). Similar findings were reported in a more recent paper by Cho analyzing 
outcomes of 672 patients (Cho et al 2010

). 
The published case reports of C5a blockadewith eculizumabin TAM comprise many children 
and adolescents;in addition there areongoingstudiesin pediatric subjects 2-17 years of age 
in PNH and in pediatric subjects aged 1 month and upwards in the atypical hemolytic uremic 
syndrome (AHUS) indication.

In a recent report, moderate liver toxicity possibly related to C5 blockade with eculizumab in 
children with aHUS has been reported (Hayes et al 2014). However, the authors of this report 
suggest that this observation is more likely disease-related rather than drug-related because 
liver toxicity has not been observed with an anti-C5 therapyin any other indication. In the 
proposed study liver function tests will be monitored, therefore, abnormalities in LFTs will be 
detected and can be acted upon as appropriate. No data is published on liver transaminase 
elevation specifically in TAM patients. However, there is unequivocal input by physicians 
treating TAM patients that such elevations are commonly seen and that these elevations can 
exceed upper level of normal thresholds manifold. There is strong consensus that this should 
not be viewed as a reason to withhold treatment with C5 blockade. 
Themain risks of anti-C5 therapies are related to infections. 
 
 The most 
important adverse effect associated with systemic eculizumab, however, is infection by 
Neisseria (N). meningitidis(e.g. meningitis). These infectionswere so far not reported in 
TAM patients butare consistent with reports of occasional,but recurrent,meningococcal 
infections seen in patients with total hereditary C5 deficiency (Haeneyetal1980; 
Cesbronetal1985; Sanal et al 1992; Delgado-Cerviño et al 2005; López-Leraetal2009; 
Zerzrietal2010); pneumococcal infections were also reported in hereditary complement 
deficiency. 
The risk to patients in this trial will be minimized by, antibiotics prophylaxis active against 
N.meningitidismandatory during the entireLFG316treatment period,adherence to the 
eligibility criteria, and close clinical monitoring.In additionall patientsshouldbe vaccinated 
against N. and patients <18year of ageshould receive vaccination for the prevention of S. 
pneumoniaeand H. influenzaetype b prior to LFG316 administration.In case vaccinationsare
not possible or will result in an unfavorable risk benefit ratio as judged by the investigator, 
vaccination can be postponed until deemed useful.For example patients with severe 
thrombocytopenia might need platelet transfusion support to tolerate s.c. or i.m. injections 
needed for vaccinations. The inherent risk of platelet infusion might lead to suchan
unfavorable risk/benefit ratio if a very low efficacy of vaccination is expected.  
Although no such events have been reported so far, as with other therapeutic antibodies, 
LFG316 is expected to carry the risk of anaphylaxis or hypersensitivity reactions. 
Fluids,vasopressors, antihistamines, bronchodilatators, and oxygen should be available at the 
clinical site to assure quick administration if needed.Overall, the potentialbenefits of anti-C5 
therapy outweigh the risks in this population of TAM patients. 
For adult patients (≥18 years) assuming 16 weeks treatmentblood volumecollected over 
52weeks of the study durationwill be approx.up to800 mL, assuming maximal duration of 
45weeks blood volumeduring the studywill beapprox.up to1050 mL.The maximum blood 
volume collected from adult patients over consecutive 8 weeks will be up toapproximately
450mL.For the pediatric patient population the maximum blood volume collectedwill depend on 
patient weight.

For children > 20kg blood volume drawn for analyses isapprox. 170mL for the 
standard 16 week treatment. In case of treatment extensionto maximum allowable 
treatment duration of 45 weeksthis would increase toup toapproximately 250mL.

For children <20kg the maximal blood volumedrawnis up to approximately 125mL
and 190mL respectively.Daily blood collection in children is ≤1% of the total blood 
volume(TBV)and maximum blood collected over 4 week is approximately 5% of 
TBV(this is only the case for the first 4 weeks of the study).Asper EMA guidance 
the maximum blood volume collected should be <3% of TBV. However, given the 
high unmet medical need and the extremely poor prognosis with standard of care the 
deviation seems to be justifiable. 
For the remaining study duration maximal blood volume collected in pediatric patient 
population over 4 consecutive weeks is less than 3% of the total blood volume.  
Additional samples for monitoring of any safety findings would be in addition to this. This is 
not considered to be a risk for this population.
Topical anesthesia might be administered at the site of blood collection in particular in 
pediatric population.
Women of child bearing potential andsexually activemale study participants need to be

Population
Approximately 40 male and female patients undergoing allo-HSCT for malignant and 
nonmalignant disease with high-risk TAM will be included in the study. The investigator must 
ensure that all patients being considered for the study meet the following eligibility criteria. 
No additional criteria should be applied by the investigator, in order that the study population 
will be representative of all eligible subjects. Patient selection is to be established by checking 
through all eligibility criteria at screening or baseline as specified below. A relevant record 
(e.g. checklist) ofthe eligibility criteria must be stored with the source documentation at the 
study site. Deviation from any entry criterion excludes a patient from enrollment into the 
study. Patients who drop out from the study for reasons other than lack of efficacy or adverse 
events considered by Investigator to be related to study treatment may be replaced.

Novartis study teamonly after enrollment(randomization)into the study.
Additionally schistocyte count should be performed byaperson blinded to study treatment.

6.7
Treatment exposure and compliance
LFG316 will be administered via intravenous infusion by the Investigator or designated study 
staff over a maximum of 2 hours. For details please refer to the Pharmacy manualprovided 
separately. Compliancewill be assuredby close medical supervision of the study personnel 
and study Monitors. Serum concentrations of total LFG316 (measure of treatment exposure) 
will be determined in all subjects treated withLFG316, as detailed inSection 8.5.
6.8
Recommended treatment of adverse events
Treatment of AEs should follow standard practice. Medication used to treat AEs must be 
recorded on the Concomitant medications/Significant non-drug therapies CRF.
As with other therapeutic antibodies, LFG316 is expected to carry therisk of anaphylaxis or 
hypersensitivity reactions. Fluids, vasopressors, antihistamines, bronchodilatators, and oxygen 
should be available at the clinical site to assure quick administration if needed.
6.9
Rescue medication
Pleaserefer to Section 3.1for description of the treatment switch in case no improvement is 
observed after treatment with LFG316 or SoC. Use of rescue medication must be recorded on 
the Concomitant medications/Significant non-drug therapies CRF after start of study drug.
6.10
Concomitant treatment
All prescription medications, over-the-counter drugs and significant non-drug therapies 
(including blood transfusions) administered or taken within the timeframe defined in the entry 
criteria prior to the start of the study and during the study, must be recorded on the Concomitant 
medications/ Significant non-drug therapies section of the CRF.
Medication entries should be specific to trade name, the single dose and unit, the frequency 
and route of administration, the start and discontinuation date and the reason for therapy.  
Incase of IgG levels below age specific normal ranges (as specifiedby local laboratories) the

use of Intravenous immunoglobulins (IVIg)up to 0.5g/kg/BW with the intention to substitute
IgG to reach a low-normal age adjusted blood levels is acceptable. Administration of IVIg
should be timed to be spaced at least 36 hours before or after administration of LFG316.
Administration of high dose IVIg(2g/kg BW or higher) in single doses is not acceptablein 
LFG316 treatment armduring the study duration.
Meningococcal vaccine(s) shouldbe administered prior to LFG316 treatment according to 
recommendations for patients with complement deficiencies if prior vaccination cannot be 
confirmed. The choice of vaccine(s) should take into account the serotypes prevalent in the 
geographic areas in which study patients will be enrolled. Based on recommendations, 
revaccination at the start of LFG316 therapy should be considered for previously vaccinated 
subjects as well as during LFG316 therapy for subjects who will receive prolonged treatment.
Whenever possible, meningococcal vaccine(s) should be administered at least two weeks prior 
to starting LFG316.In addition, patients<18 years old should receive vaccination for the 
prevention of S.pneumoniaeand H. influenzaetype b prior to LFG316 treatment.In case 
vaccinationsarenot possible or will result in an unfavorable risk benefit ratio as judged by the
Investigator, vaccination can be postponed until it is likely to be effective.
If patients are not already on antibiotic prophylaxis or treatment active against local strains of 
N. meningitis and S. pneumoniaeduring any time duringthe treatment with LFG316 or 
8weeks after lastdose, penicillin V 500 mg twice a day or erythromycin 500 mg 
(orequivalently effective doses in pediatric patients) twice a day must be given to patients in 
LFG316 treatmentarm. If local strains of either of these bacteria are resistant to either of
these or the patient is allergic or cannot otherwise tolerate the standard prophylactic treatment, 
the choice of antibiotic will be made upon local guidelines or the recommendation of the local 
ID consultant.

Discontinuationand study completion
7.1
Discontinuation of study treatment
Subjectsmay voluntarily discontinuestudy treatment for any reason at any time.
The investigator mustdiscontinue study treatment for a given subject if, on balance, he/she 
believes that continuationwould be detrimental to the subject’s well-being.
Study treatment mustbe discontinued under the following circumstances: 
Subject withdraws consent.
Patients showing worsening disease between week 2 and 3,or absence of response at 
week 4 oranytime thereafter (as defined in the study Section 3.1) will be considered a 
failure and can be switched to receive the alternative treatment (SoC or LFG316). 
Patients on LFG316 that as per judgmentof Investigator require plasmapheresisor 
prohibited medication as per Section 5.2.
Patients with confirmed TTP (as per ADAMST13test result).
Treatment discontinuation and switch to SoC might also occur after consultation with 
Sponsor in case of treatment related SAE, or any other AE that in judgmentof Investigator 
warrants LFG316 treatment discontinuation. 
Patients who wish to discontinue eitherstudy treatment,whether initially allocated or 
subsequently switched,but who didnot withdraw their consent,will be asked to continue with 
study visits as per assessment schedule if possible.Every effort will be made to assess the 
parameters required for assessment of hematological and complete response at the time of 
discontinuation (i.e.,schistocytes, transfusion independence, proteinuria<30mg/dL and 
eGFR).In case patientwithdraws consent, theprocedure described in Section 7.3needs to be 
followed.
7.2
Study completion and post-study treatment
Each subject will be required to complete the study in its entirety and thereafter no further 
study treatment will be made available to them. Study completion is defined as when the last 
subject completes their End of Study visit, and any repeat assessments associated with this 
visit have been documented and followed-up appropriately by the Investigator, or in the event 
of an early total study termination decision, the date of that decision.
At a minimum, subjects will be contacted for safety evaluations during the 30 days following 
the Study Completion visit, including a final post-study safety contact at the 30-day point. 
Documentation of attempts to contact the subjectshould be recorded in the source 
documentation.
The investigator must provide follow-up medical care for all subjects who are prematurely 
withdrawn from the study, or must refer them for appropriate ongoing care.

Protocol No. CLFG316X2202
7.2.1
Lostto follow-up
For subjects whose status is unclear because they fail to appear for study visits without stating 
an intention to discontinue or withdraw, the investigator should show "due diligence" by 
documenting in the source documents steps taken to contact the subject, e.g. dates of 
telephone calls, registered letters, etc. A subject should not be formally considered lost to 
follow-up until his/her scheduled end of study visit would have occurred.
7.3
Withdrawal of consent
Subjects may voluntarily withdraw consent to participate in the study for any reason at any 
time.
Withdrawal of consent occursonly when a subject does not want to participate in the study 
anymoreanddoes not want any further visits or assessmentsanddoes not want any further 
study related contactanddoes not allow analysis of already obtained biologic material. If not 
allabove criteria are met, please refer to procedure outline in Section 7.1.
If a subjectwithdraws consent, the investigator must make every effort to determine the 
primary reason for this decision and record this information. Study treatment must be 
discontinued and no further assessments conducted. Allbiological material that has not been 
analyzed at the time of withdrawal must not be used. Further attempts to contact the subject 
are not allowed unless safety findings require communicating or follow-up.
7.4
Study stopping rules
The study may be put on hold pending full safety data review done bytheData Monitoring 
Committee (DMC)if one or more of the following criteria are met: 
Two or more investigational drug (LFG316) related SAEs are reported 
Other clinically significant events that in the opinion of the investigator or sponsor 
preclude continuation ofdosing (especially events that are suspected to be drug 
related).
A DMCwill also review available safety data after the first 5 patients complete 4weeks of 
LFG316 treatmentand approximately every 3 months thereafter during the study. 
When possible,DMC meetings will be aligned with planned IAs. Inthecase of any safety 
concerns identified during the study (as described above) or faster than anticipated 
recruitment, DMCmeetings might happen more regularly.
7.5
Early study termination
The studycan be terminated at any time for any reason by Novartis. Should this be necessary, 
subjectsshould be seen as soon as possible and treated as a prematurely withdrawn subject. 
The investigator may be informed of additional procedures to be followed in order to ensure 
that adequate consideration is given to the protection of the subject’s interests.
TheInvestigator will be responsible for informing IRBs/IECs of the early termination of the 
trial.

Informed consent procedures
Eligiblesubjects may only be included in the study after providing written (witnessed, where 
required by law or regulation), IRB/IEC-approved informed consent(assent in case of 
children).
All subjects must be counseled about the risk of meningococcal infections as well as other 
infections, such as those caused by S.pneumoniae, H.influenzaetype b, and Aspergillus
Corporate Confidential Information
spp 
as a part of the informed consent process.
If incapable of doing so, in cases where the subject’s representative gives consent, the subject 
should be informed about the study to the extent possible given his/her understanding. If the 
subject is capable of doing so, he/she should indicate assent by personally signing and dating 
the written informed consent document or a separate assent form.
Informed consent must be obtained before conducting any study-specific procedures (i.e. all 
of the procedures described in the protocol). The process of obtaining informed consent 
should be documented in the subject source documents.
The date of signing off theinformed consent form (and the date of withdrawal, iflater

Adverse events
An adverse event (AE) is any untoward medical occurrence (i.e., any unfavorable and 
unintended sign [including abnormal laboratory findings], symptom or disease) in a subject or 
clinical investigation subject after providing written informed consentfor participation in the 
study. Therefore, an AE may or may not be temporally or causally associated with the use of a 
medicinal (investigational) product.
The occurrence of adverse events should be sought by non-directive questioning of the subject 
at each visit during the study. Adverse events also may be detected when they are volunteered 
by the subject during or between visits or through physical examination, laboratory test, or 
other assessments.
Abnormal laboratory values or test results constitute adverse events only if they fulfill at least 
one of the following criteria:
they induce clinical signs or symptoms, 
they are considered clinically significant, 
they require therapy. 
Clinically significant abnormal laboratory values or test results shouldbe identified through a 
review of values outside of normal ranges/clinically notable ranges, significant changes from 
baseline or the previous visit, or values which are considered to be non-typical in patientswith 
underlying disease. Investigators have the responsibility for managing the safety of individual 
subjectand identifying adverse events. Alert ranges for liver related eventsare included in
Section 9.3

Page 57
Amended Protocol Version v05 Clean
Protocol No. CLFG316X2202
Adverse events must be recorded on the Adverse Events CRF for subjects thatpass screening 
and enterinto the study. The adverse events should be reported according to the signs, 
symptoms or diagnosis associated with them, and accompanied by the following information:
1. Adverse events will be assessed according to Common Terminology Criteria for Adverse 
Events (CTCAE) version 4.03. If CTC-AE grading does not exist for an adverse event, use:
1=mild, 
2=moderate,
3=severe
4=life threatening.
CTC-AE grade 5 (death) is not used, but is collected in other CRFs (e.g. Study Completion, 
Death/Survival).
2. its relationship to thestudy treatment (no/yes), or
investigational treatment (no/yes), or other study treatment(non-investigational) (no/yes), 
orboth or indistinguishable,
3. its duration (start and end dates) or if the event is ongoing an outcome of not 
recovered/not resolved should be reported.
4. whether it constitutes a serious adverse event (SAE) See Section 9.2for definition of SAE
5. action taken regarding [study/investigational] treatment(select as appropriate). 
All adverseevents should be treated appropriately. Treatment may include one or more of 
the following: 
no action taken (i.e. further observation only)
study treatmentdosage adjusted/temporarily interrupted 
study treatmentpermanently discontinued due to this adverse event 
concomitant medication given 
non-drug therapy given 
subjecthospitalized/subject’shospitalization prolonged 
Once an adverse event is detected, it should be followed until its resolution or until it is 
judged to be permanent, and assessment should be made at each visit (or more frequently, if 
necessary) of any changes in severity, the suspected relationship to the study drug, the 
interventions required to treat it, and the outcome.
Information about common side effects already known about the investigational drug can be 
found in the Investigator Brochure (IB) or Core Data Sheet (for marketed drugs) or will be 
communicated betweenIB updates in the form of Investigator Notifications. This information 
will be included in the subjectinformed consent and should be discussed with the subject
during the study as needed.

The investigator should also instruct each subjectto report any new adverse event (beyond the 
protocol observation period) that the subject, or the subject’spersonal physician, believes 
might reasonably be related to study treatment. This information should be recorded in the 
investigator’s source documents;however, if the AE meets the criteria of an SAE, it must be 
reported to Novartis.
9.2
Serious adverse event reporting
9.2.1
Definition of SAE
An SAE is defined as any adverse event (appearance of (or worsening of any pre-existing) 
undesirable sign(s), symptom(s) or medical conditions(s) which meets any one of the 
following criteria:
is fatal or life-threatening 
results in persistent or significant disability/incapacity
constitutes a congenital anomaly/birth defect
requires inpatient hospitalization or prolongation of existinghospitalization, unless 
hospitalization is for:
routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition 
elective or pre-planned treatment for a pre-existing condition and has not worsened 
since the start of study drug
treatment on an emergency outpatient basis for an event not fulfilling any of the 
definitions of a SAE given above and not resulting in hospital admission 
social reasons and respite care in the absence of any deterioration in the patient’s 
general condition
is medically significant, i.e. defined as an event that jeopardizes the subjector may require 
medical or surgical intervention.
Life-threatening in the context of a SAE refers to a reaction in which the subjectwas at risk of 
death atthe time of the reaction; it does not refer to a reaction that hypothetically might have 
caused death if more severe.
All malignant neoplasms will be assessed as serious under “medically significant” if other 
seriousness criteria are not met.
Any suspected transmission via a medicinal product of an infectious agent is also considered a 
serious adverse reaction.
Medical and scientific judgment should be exercised in deciding whether other situations 
should be considered serious reactions, such as important medical events that might not be 
immediately life threatening or result in death or hospitalization but might jeopardize the 
patient or might require intervention to prevent one of the other outcomes listed above. 
Examples of such events are intensive treatment in an emergency room or at home for allergic 
bronchospasm, blood dyscrasias or convulsions that do not result in hospitalization or
development of dependency or abuse.

Novartis

Page 59
Amended Protocol Version v05 Clean
Protocol No. CLFG316X2202
All AEs (serious and non-serious) are captured on the CRF;SAEs also require individual 
reporting to DS&E as per Section 9.2.2.
9.2.2
SAE reporting
To ensure subjectsafety, every SAE, regardless of causality, occurring after the subjecthas 
provided informed consent and until 30 days after the last study visit.must be reported to 
Novartis within 24 hours of learning of its occurrenceas described below. Any SAEs 
experienced after thisshould only be reported to Novartis if the investigator suspects a causal 
relationship to study treatment. 
Recurrent episodes, complications, or progression of the initial SAE must be reported as 
follow-up to the original episode, regardless of when the event occurs. This report must be 
submitted within 24 hours of the investigator receiving the follow-up information. An SAE 
that is considered completely unrelated to a previously reported one should be reported 
separately as a new event.
Information about all SAEs (either initial or follow up information)is collected and recorded 
on the paper Serious Adverse Event Report Form. The investigator must assess the 
relationship to each specific component of study treatment (if study treatment consists of 
several drugs)complete the SAE Report Form in English, and send the completed, signed 
form by fax within 24 hours after awarenessof the SAEto the local Novartis Drug Safety and 
Epidemiology Department, notifying the Clinical Trial Leader.Contact information islisted 
in the Site Operations Manual. 
The original copy of the SAE Report Form and the fax confirmation sheet must be kept with 
the sourcedocumentation at the study site.Follow-up information shouldbe provided using a 
new paper SAE Report Form stating that this is a follow-up to a previously reported SAE.
Follow-up information provided should describe whether the event has resolved or continues, 
if and how it was treated, whether the treatment codewas broken or not and whether the 
subjectcontinued or withdrew from study participation. Each re-occurrence, complication, or 
progression of the original event should be reported as a follow-up to that event regardless of 
when it occurs.
If the SAE is not previously documented in the Investigator’s Brochure or Package Insert 
(new occurrence) and is thought to be related to the investigational treatment a Drug Safety 
and Epidemiology Department associate may urgently require further information from the 
investigator for Health Authority reporting. Novartis may need to issue an Investigator 
Notification (IN) to inform all investigators involved in any study with the same 
investigational treatment that this SAE has been reported.Suspected Unexpected Serious 
Adverse Reactions (SUSARs) will be collected and reported to the competent authorities and 
relevant ethics committees in accordance with EU Guidance 2011/C 172/01 or as per national 
regulatory requirements in participating countries.
9.3
Liver safety monitoring
To ensure subject safety and enhance reliability in determining the hepatotoxic potential of an 
investigational drug, a standardized process for identification, monitoring and evaluation of 
liver events has to be followed. 

Novartis

Page 60
Amended Protocol Version v05 Clean
Protocol No. CLFG316X2202
The following twocategoriesof abnormalities / adverse events have to be considered during 
the course of the study:
Liver laboratory triggers, which will require repeated assessments of the abnormal 
laboratory parameter
Liver events, which will require close observation and follow-up 
Pleaserefer to Table 9-1and Table9-2for complete definitions of liver laboratory triggers 
and liver events.
Every liver laboratorytrigger orliver event should be followed up by the investigator or 
designated personal at the trial site, as summarized below and detailed inTable9-2.
For the liver laboratory trigger:
Repeating the liver function test (LFT)within the next week to confirm elevation
These LFT repeats should be performed using the central laboratory if possible. If this is not 
possible, then the repeats can be performed at a local laboratory to monitor the safety of the 
patient. Repeats laboratory should then be performed at central laboratory as soon as possible. 
For the liver events:
Repeating the LFT to confirm elevation as appropriate
Hospitalization of the subject if appropriate
A causality assessment of the liver eventvia exclusion of alternative causes (e.g. 
disease, co-medications)
If liver safety eventsare possibly related to the study drug and are unlikely to be part 
of the TAM presentation, discontinuation of the investigational drugmay be 
consideredafter consultation with Sponsor. 
An investigation of the liver event which needs to be followed until resolution
These investigations can include serology tests, imaging and pathology assessments, 
hepatologist’s consultancy, based on investigator’s discretion. All follow-up information, and 
the procedures performed should be recorded as appropriate in the CRF.

9.5
Pregnancy reporting
To ensure patient safety, each pregnancy in a subjecton study drug must be reported to 
Novartis within 24hours of learning of its occurrence. The pregnancy should be followed up 
to determine outcome, including spontaneous or voluntary termination, details of the birth, 
and the presence or absence of any birth defects, congenital abnormalities, or maternal and/or 
newborn complications. The study drug must be discontinued, though the subjectmay stay in 
the study, if she wishes to do so. All assessments that are considered as a risk during 
pregnancy must not be performed. The subjectmay continue all other protocol assessments. 
Pregnancymust be recorded on a Pharmacovigilance Pregnancy Form and reported by the 
investigator to the local Novartis Drug Safety and Epidemiology Department. 
Pregnancyfollow-up should be recorded on the same form and should include an assessment 
of the possible relationship to the Novartis study drug of any pregnancy outcome. Any SAE 
experienced during pregnancy must be reported on anSAE Report Form.

Data review and database management
10.1
Site monitoring
Before study initiation, at a site initiation visit or at an investigator’s meeting, a Novartis 
representative will review the protocol and CRFs with the investigators and their staff. 
Duringthe studyNovartis employs several methods of ensuring protocol and GCP 
compliance and the quality/integrity of the sites’ data. Themonitor will visit the site to check 
the completeness of subjectrecords, the accuracy of entries on the CRFs, the adherence to the 
protocol and to Good Clinical Practice, the progress of enrollment, and to ensure that study 
drug is being stored, dispensed, and accounted for according to specifications. Key study 
personnel must be available to assist the monitor during these visits.
Continuous remote monitoring of each site’s data may be performed by Novartis.
Additionally, a central analytics organization may analyse data & identify risks & trends for 
site operational parameters, and provide reports to Novartis Clinical Teams to assist with trial 
oversight.
The investigator must maintain source documents for each subject in the study, consisting of 
case and visit notes (hospital or clinic medical records) containing demographic and medical 
information, laboratory data, electrocardiograms, and the results of any other tests or 
assessments. All information on CRFs must be traceable to these source documents in the 
subject
's file. The investigator must also keep the original informed consent form signed by 
the subject (a signed copy is given to the subject).
The investigator must give the monitor access to all relevant source documents to confirm 
their consistency with the CRF entries. Novartis monitoring standards require full verification 
for the presence of informed consent, adherence to the eligibilitycriteria, documentation of 
SAEs, and the recording of data that will be used for all primary and safety variables. 
Additional checks of the consistency of the source data with the CRFs are performed 
according to the study-specific monitoring plan. No information in source documents about 
the identity of the subjects will be disclosed.

Designated investigator staff will enter the datarequired by the protocol into the Electronic 
Case Report Forms using fully validated software that conforms to 21 CFR Part 11 
requirements. Designated investigator site staff will not be given access to the EDC system 
until they have been trained. Automatic validation programs check for data discrepancies and, 
by generating appropriate error messages, allow the data to be confirmed or corrected before 
transfer of the data to the CRO working on behalf of Novartis. TheInvestigator must certify 
that the dataentered into the Electronic Case Report Forms are complete and accurate. 
Afterdatabase lock, the investigator will receive a CD-ROM or paper copies of the subject 
data for archiving at the investigational site.
Data not requiring a separate written record will be defined in the Site Operations Manual and 
assessment schedule and canbe recorded directly on the CRFs. All other data captured for this 
study will have an external originating source (either written or electronic)withthe CRF not 
being considered as source.
All data should be recorded, handled and stored in a way that allows its accurate reporting, 
interpretation and verification.
CRO working on behalf of Novartisreview the data entered into the eCRFs by investigational 
staff for completeness and accuracy and instruct the site personnel to make any required 
corrections or additions. Queries are sent to the investigational site using an electronic data 
query. Designated investigator site staff is required to respond to the query and confirm or 
correct the data. If the electronic query system is not used, a paper Data Query Form will be 
faxed to the site. Site personnel will complete and sign the faxed copy and fax it back to CRO
working on behalf of Novartiswho will make the correction to the database.
Concomitant medications entered into the database will be coded using the WHO Drug 
Reference List, which employs the Anatomical Therapeutic Chemical classification system. 
Medical history/current medical conditions and adverse events will be coded using the 
Medical dictionary for regulatory activities (MedDRA) terminology.
Laboratory samples will be processed centrally and the results will be sent electronically to 
Novartis (or a designated CRO).
ECG readings will be processed centrally and the results will be sent electronically to 
Novartis (or a designated CRO).
At the conclusion of a non-IRT study, the occurrence of any emergency code breaks will be 
determined after return of all code break reports and unused drug supplies to Novartis.

(whether according to the protocol-defined rules allowing a switch to the alternative treatment 
arm, or not) or due to treatment-related safety reasons will be considered non-responders in 
this analysis. Data from these patients collected after switching treatment will be considered 
as supportive data but will not be included in the primary analysis.
11.4.2
Statistical model, hypothesis, and method of analysis
The primary analysis will compare all randomized patients according to the treatment they 
were assigned. 
Results for hematological response will be categorized as providing evidence of good, 
satisfactory or poor efficacy as defined by the rules below. 
Good efficacy: Pr (Δ>30%¦ data) ≥0.5 and Pr (Δ>0¦ data) ≥0.9
Satisfactory efficacy:  Pr (Δ≥10%
¦ data) ≥0.5 and Pr (Δ>0
¦ data) ≥0.9
Poor efficacy: Pr (Δ≥10%¦ data) < 0.5 or Pr (Δ>0¦ data) < 0.9
where Δ is the differencein percentage pointsin response rates (LFG316 -control).
The analysis of hematological response at 17 weeks will present posterior probabilities of 
meeting the outcome criteria as defined above. The prior distribution for the response rate in 
each group will be assumed to be a neutral non-informative Beta (1/3, 1/3) distribution.

11.4.3
Handling of missing values/censoring/discontinuations
Patients who discontinue treatment due to lack of efficacy (defined as either meeting the 
criteria defined in Section 3.1for switching treatments or having reason for discontinuation 
marked as “lack of efficacy” at the study completion visit) are defined to be non-responders. 
Other patients,for whom hematological response cannot be assessed due to discontinuation 
for treatment-related safety reasons,will be considered to be non-responders. Hematological 
response for patients who discontinue for any other reason will be determined based on their 
available data at the time of discontinuation. 
Given the severe nature of the indication and the need for close monitoring of these patients it 
is expected that there will be very little truly missing data.
11.4.4
Supportive analyses
A supportive analysis will compare patients according to the degree of complement blockade 
achieved. And given schistocyte counts, erythrocytes, platelets, and proteinuria are involved 
in definitions of treatment failure or successeach will be summarized and plotted over time, 
with the possibility of further analyses.
The effect of presence/absence of proteinuria at baseline (a key prognostic factor of response) 
on the response rates in each group will be investigated. 
 
11.5
Analysis of secondary and exploratory variables
11.5.1
Efficacy / Pharmacodynamics
Secondary variables supporting the secondary objectives will include:
Complete response, defined as hematologicalresponse and no proteinuria as 
determined by proteinuria<30mg/dLand eGFRdoubled or not less than 0.85 x lower 
limit of normal
Number of patients switching treatment and timeat which the switch occurred
Non-relapse mortality

Corporate Confidential Information
Overall survival
Complete response will be analyzed in the same way as the primary variable of hematological 
response. The number of patients switching treatment will be summarized. Time to treatment 
switch, non-relapse mortality and overall survival will be summarized using time to event
methods. Further details will be provided in the Reporting and Analysis Plan (RAP).
Further details on the analysis and presentation of these variables will be provided in the RAP.

11.5.3
Pharmacokinetics
Total LFG316 serum concentration data will be listed by treatment, subject, and 
visit/sampling time point. Descriptive summary statistics will beprovided by treatment and 
visit/sampling time point, includingthe frequency (n, %) of concentrations belowthe LLOQ 
and reported as zero. 
Summary statistics will include mean (arithmetic and geometric), SD, CV (arithmetic and 
geometric), median, minimum and maximum. Anexception to this is Tmax where median, 
minimum and maximum will be presented. Concentrations below LLOQ will be treated as 
zero in summary statisticsand for PK parameter calculations. A geometric mean will not be 
reported if the dataset includes zero values.Pharmacokinetic parameters will be calculated as 
described inSection 8.5

Responsibilities of the investigator and IRB/IEC
Before initiating a trial, the investigator/institution should obtain approval/favorable opinion 
from the Institutional Review Board/Independent Ethics Committee (IRB/IEC) for the trial 
protocol, written informed consent form, consent form updates, subject recruitment 
procedures (e.g.advertisements) and any other written information to be provided to subjects. 
Prior to study start, the investigator is required to sign a protocol signature page confirming 
his/her agreement to conduct the study in accordance with these documents and all of the 
instructions and procedures found in this protocol and to give access to all relevant data and 
records to Novartis monitors, auditors, Novartis Quality Assurance representatives, designated 
agents of Novartis, IRBs/IECs, and regulatory authorities as required. If an inspection of the 
clinical site is requested by a regulatory authority, the investigator must inform Novartis 
immediately that this request has been made.
For multi-center trials, a Coordinating Investigator will be selected by Novartis around the 
time of Last Patient Last Visit to be a reviewer and signatory for the clinical study report.
12.3
Publication of study protocol and results
Novartis assures that the key design elements of this protocol will be posted in a publicly 
accessible database such as clinicaltrials.gov. In addition, upon study completion and 
finalization of the study report the results of this trial will be either submitted for publication
and/or posted in a publicly accessible database of clinical trial results.

Protocol adherence
This protocol defines the study objectives, the study procedures and the data to be collected 
on study participants. Additional assessments required to ensure safety of subjects should be 
administered as deemed necessary on a case by case basis. Under no circumstances should an 
investigator collect additional data or conduct any additional procedures for any research 
related purpose involving any investigational drugs.
Investigators must apply due diligence to avoid protocol deviations. If the investigator feels a 
protocol deviation would improve the conduct of the study this must be considered a protocol 
amendment, and unless such an amendment is agreed upon by Novartis and approved by the 
IRB/IEC/REB it cannot be implemented. All significant protocol deviations will be recorded 
and reported in the CSR.

13.1
Protocol Amendments
Any change or addition to the protocol can only be made in a written protocol amendment that 
must be approved by Novartis, Health Authorities where required, and the IRB/IECprior to 
implementation. 
Onlyamendments that areintended to eliminate an apparent immediate hazard to subjects 
may be implemented,provided the Health Authorities and the reviewing IRB/IEC are 
subsequentlynotified by protocol amendment.
Notwithstanding the need for approval of formal protocol amendments, the investigator is 
expected to take any immediate action required for the safety of any subject included in this 
study,even if this action represents a deviation from the protocol. In such cases,the CTL 
should be informed and (serious) adverseevent reporting requirements (Section 9) followed 
as appropriate.
