Purpose and rationale 
Crizanlizumab is a humanized monoclonal antibody that binds P-selectin 
and was previously found to reduce the median annualized rate of VOC 
at 5 mg/kg by 45.3% compared to placebo. Clinical and toxicological 
studies performed to date for crizanlizumab were conducted using 
Reprixys material (SelG1 mAb). To ensure supply of future clinical 
studies as well as commercial demand, Novartis has optimized the 
production of crizanlizumab. The Novartis material (SEG101 mAb) drug 
substance (DS) and drug product (DP) will be manufactured at Novartis 
sites. The change in manufacturing cell line is not expected to impact the 
bioavailability or activity of the compound. 
The purpose of the CSEG101A2202 study is to characterize the PK and 
PD of SEG101 and to evaluate the safety and efficacy of SEG101. 
Primary Objective(s) 
and Key Secondary 
Objective 
To characterize PK of crizanlizumab at 5.0 mg/kg in SCD patients. 
To characterize PD (P-selectin inhibition) of crizanlizumab at 5.0 mg/kg 
in SCD patients 
Secondary Objectives 
To assess the efficacy of crizanlizumab in SCD patients in terms of 
annualized rate of VOC events leading to healthcare visit in 
clinic/ER/hospital, annualized rate of VOC events treated at home, 
annualized rate of hospitalizations and ER visits, annualized rate of 
ER/hospitalization, annualized rate of each subcategory of VOC event 
(uncomplicated pain crisis, acute chest syndrome, hepatic sequestration, 
splenic sequestration, priapism), annualized rate of VOC events. 
To assess the safety and tolerability of crizanlizumab in terms of the 
number, seriousness, severity, and causality assessments of treatment 
emergent adverse events and other safety data as considered 
appropriate and absolute change from baseline in hemoglobin 
Study design 
Open-label, single arm study of crizanlizumab therapy in SCD patients. 
Population 
55 male and female SCD patients ages 16-70 years who experienced at

Safety assessments 
Safety will be monitored by assessing the following parameters: 
-Vital signs 
-Physical exam 
-ECG in triplicates at all PK assessment timepoints [central review] 
-Hematology, blood chemistry, coagulation and urinalysis (additional 
laboratory tests will be performed at the investigator’s discretion for 
safety measures in the event of an adverse event) 
-Pregnancy 
 
 
 
-Monitoring of AEs/SAEs 
Data analysis 
PK parameters including AUC and Cmax will be derived from individual 
concentration-time profiles after the first dose and the 5th dose. The 
inter-subject variations and CV% will be presented for the primary PK 
parameters. The point estimate and the corresponding two-sided 90% 
confidence interval (CI) for the mean of the log-transformed primary PK 
parameters after single dose and multiple doses will be derived 
respectively. The point estimate and CI will be anti-log transformed to 
obtain the point estimate and the 90% confidence interval for the 
geometric mean on the original scale. The descriptive statistics (n, mean, 
CV%, standard deviation (SD), median, geometric mean, geometric 
CV%, minimum and maximum) will be presented for all PK parameters 
except Tmax, where only n, median, minimum and maximum will be 
presented. Descriptive statistics for crizanlizumab concentration will be 
presented at each scheduled timepoint. 
PD-AUCd15 and PD-AUCd29 will be derived from the %P-selectin 
inhibition time profiles of week 1 and week 15, respectively. The point 
estimate and the corresponding two-sided 90% CI for the mean of the 
log-transformed PD-AUC after single dose and multiple doses will also 
be provided. The point estimate and CI will be anti-log transformed to 
obtain the point estimate and the 90% confidence interval for the 
geometric mean on the original scale. Descriptive statistics for PD 
inhibition will be presented at each scheduled timepoint.

Amendment 01 (04-Jun-2018) 
Amendment rationale 
The study is currently open for enrollment with 21 subjects enrolled to date. 
Due to the ongoing high unmet medical need for prevention of VOC in SCD, particularly for 
patients age <18 years old, and the unexpected delay in start of the SEG101 phase 2 
(CSEG101B2201) trial for ages 6 months to 18 years, the decision was made to expand the 
inclusion age in CSEG101A2202 to include 16 and 17 year old subjects. This is based on the 
well-established and widely-accepted view that there is no meaningful difference in PK 
between adolescents (here ages 16-<18 years) and adults 18 years and older. Monoclonal 
antibodies are distributed within the vascular and extracellular spaces by mechanisms 
dominated by convection, and predominately catabolized by lysosomal enzymes to small 
peptides and amino acids. It is unlikely that these (the vascular and extracellular fraction in the 
body and enzyme activity) differ in age 16 vs. 18, therefore PK is expected to be similar between 
age 16 vs. 18. 
Participating investigators have provided feedback after enrolling their initial patients to the 
study. They suggested the protocol inclusion and exclusion criteria be examined and modified 
regarding the timing of prior VOCs and historical testing information as well as current 
treatment be clarified. 
This amendment also clarifies that the VOC events should not be reported as adverse events. 
Further review of the secondary endpoints led to the changes from the number of efficacy 
related endpoints to the annualized (rates) – this accounts for any early subject withdrawal by 
setting one year as a standard time period. 
Additional PK samples have been added to align with the IG sample collection timelines. 
Additional safety information has led to the adjustment of the dose modification guidance for 
this compound, including the removal of the dosing modification requirements for hypertension, 
the addition of dosing modification guidelines for QTc prolongation, as well the correction of 
editorial and typographical errors.

Background 
1.1 
Overview of disease pathogenesis, epidemiology and current 
treatment 
Sickle cell disease (SCD) is a rare autosomal recessive blood disorder caused by a single 
missense mutation (Glu6Val) in the β-globin gene that renders the mutant hemoglobin less 
soluble and prone to polymerization upon deoxygenation. The polymerization of hemoglobin 
causes deformation of the erythrocyte to give the cell a “sickle” shape (Bookchin 1996), and 
leads to chronic hemolysis, anemia, and vaso-occlusion (NHLBI, The Management of Sickle 
Cell Disease. NIH Publication No.022117; Wethers 2000). SCD is the most common single 
gene disorder in African Americans, affecting approximately 1 in 375-600 persons of African 
ancestry (Clinical Practice Guideline No. 6. April 1993; Nietert 2002). Sickle cell conditions 
are also common among people of Mediterranean countries, Africa, the Caribbean and parts of 
South and Central America (Clinical Practice Guideline No. 6. April 1993; Nietert 2002). 
In SCD, lysis of sickle red cells, cell membrane damage and oxidative stress, repeated ischemic 
damage, and microvasculature injury are due to the adhesive interactions between sickle red 
cells and the endothelium, which culminate in a pro-inflammatory environment (Embury 2004; 
Chiang 2005). In this environment of chronic vascular inflammation, the adherence of 
leukocytes, platelets and sickle red cells to activated blood vessel endothelium and to each other 
is believed to be the primary cause of microvasculature blockage and vaso-occlusive crisis 
(VOC), the clinical hallmark of SCD, typically associated with intense pain. Additional factors 
such as the rigidity of sickle red cells, increased blood viscosity, and local vasoconstriction have 
also been identified as potentially contributing to the vaso-occlusion process. VOC includes 
pain crises (defined as an acute onset of pain for which there is no other medically determined 
explanation other than vaso-occlusion and which requires therapy with oral or parenteral 
opioids or parenteral NSAIDs) as well as other complicated crises, such as acute chest syndrome 
(ACS), priapism, and hepatic or splenic sequestration (Maitre et al. 2000; Vichinsky et al. 2000). 
VOC accounts for over 90% of hospital admissions in adult SCD patients (Matsui et al. 2001; 
Chiang 2005; Okpala 2006). 
SCD patients also suffer from cerebrovascular complications, ranging from clinically evident 
acute stroke to transient silent ischemic infarct (Platt 2006). Other chronic complications 
include functional asplenia, leaving patients more susceptible to infection, (Clinical Practice 
Guideline No. 6. April 1993), bone growth retardation and avascular necrosis renal dysfunction 
(Saborio 1999), and issues of the biliary tree (gallstones, congestion), eyes (retinopathy) 
(Charache 1996), and soft tissue (leg ulcers) (Ashley-Koch 2000; Gladwin et al., 2004; Gladwin 
2005). Chronic pain and opioid abuse are also common (Smith 1996). As a result, there is an 
approximately 20 to 30 year reduction in life expectancy in SCD patients (Platt et al. 1994). 
Hemoglobin values for SCD patients vary, but typically range from 6 to 10 g/dL, but some 
patients can live with a baseline hemoglobin of 4 g/dL or lower. Chronic hemolysis results in 
other abnormal labs, including reticulocytosis, low haptoglobin, and increased free hemoglobin, 
LDH, indirect bilirubin (and, by extension, total bilirubin). In young SCD patients, glomerular 
filtration rate (GFR) is substantially increased (hyperfiltration: MDRD-GFR >130 in women, 
>140 ml/min per 1.73 m2 in men) but tends to decrease progressively with time, and 4-5% of 
these patients in the US develop stage 5 chronic renal disease (CRD) (Hirschberg 2010). SCD

patients are also more susceptible to parvovirus B19 infection which can arrest erythropoiesis 
and lead to aplastic crisis (Heegaard 2002). 
SCD has three common variants: homozygous SCD (hemoglobin SS disease), doubly 
heterozygous sickle hemoglobin C disease (hemoglobin SC disease) and the sickle β- 
thalassemia. The most common and severe form of the disease occurs in individuals who inherit 
two copies of the HbS variant (HbSS) and the primary hemoglobin in their red blood cells is 
sickle hemoglobin. Other individuals can be affected as compound heterozygotes with one copy 
of the HbS gene and one or more additional mutations, resulting in varying severities of the 
disease. HbSC results in a mild-to-moderate form of the disease. HbS β-thalassemia variants 
(β0 or β+) result in a range of clinical severities: HbSβ0 is a severe form, whereas HbSβ+ can be 
moderate or mild based on the contribution of each variant to the total hemoglobin of the patient. 
Other more rare variants can result if in addition to the HbS gene, another abnormal hemoglobin 
is inherited from the other parent, such as D, G or O-Arab. The sickle red cells gene is most 
commonly present in individuals heterozygous for HbS and HbA. These individuals carry the 
sickle cell trait and are asymptomatic (Clinical Practice Guideline No. 6. April 1993; Nietert et 
al. 2002). 
All individuals that are homozygous or compound heterozygous for HbS show some clinical 
manifestations of SCD. Clinical signs appear within the first 6 months of life but there is 
considerable variability in severity (Gill et al. 1995). Disease severity is thought to depend on 
a complex interaction of genetic, rheologic and hematologic factors, as well as microvascular 
and endothelial factors. Therefore, despite the capacity to determine genotype, the ability to 
predict disease course from birth is limited (Thomas 1997). The frequency of VOC and pain 
severity varies considerably among patients and in the same patient over time. Moreover, a 
recent study (PiSCES) evaluating health related quality of life issues in SCD patients indicated 
that VOC might be significantly underreported among SCD patients (McClish et al. 2005). 
Treatment for SCD includes supportive care for VOC. The two most common symptomatic 
treatments are blood transfusions and analgesics. Blood transfusions both increase hemoglobin 
level and lower the proportion of sickled cells, thereby increasing oxygen delivery to tissues 
and potentially reducing pain. Severe pain is often treated with narcotics but their use is 
controversial due to concerns of narcotic addiction and tolerance. Other complications of 
narcotic use are drug-seeking behavior, sedation and respiratory depression. Oxygen 
management has been utilized to treat VOC, despite the lack of strong evidence supporting its 
effectiveness. Rehydration is also used during VOC with some apparent benefit (NHLBI, The 
Management of Sickle Cell Disease. NIH Publication No.022117; Yale 2000). 
Preventative therapies for SCD include chronic red cell transfusion programs to reduce the 
incidence of stroke in high-risk patients, Hydroxyurea/Hydroxycarbamide (HU/HC, 
Droxia/Siklos) is approved for VOC. The mechanisms by which HU/HC produces its beneficial 
effects are uncertain but likely involve increasing hemoglobin F levels in RBCs, thereby 
decreasing the amount of hemoglobin S polymerization. Hydroxyurea is cytotoxic, 
myelosuppressive and teratogenic (Charache et al. 1995), and the long-term effects of 
hematologic toxicities, organ damage and carcinogenicity are currently unknown (NIH 
Consensus and State-of -the Science Statements 2008). L-glutamine was recently approved by 
the FDA to reduce the complications of sickle cell disease in adult and pediatric patients 5 years 
and older. Bone marrow transplantation may be considered and can be curative, but a limited

number of patients are eligible, and this carries a high risk of morbidity and mortality (NHLBI 
The Management of Sickle Cell Disease. NIH Publication No.022117). Thus, SCD is a life- 
threatening disease with severe morbidities and represents a major unmet medical need. 
The recognition that adherence of leukocytes, platelets and sickle red cells to blood vessel 
endothelium and to each other to have a primary role in VOC led to further research into the 
selectins, which mediate the first steps in the recruitment of leukocytes to specific tissues. Under 
shear flow in the blood, leukocytes first tether and begin rolling on vascular endothelium, 
eventually adhering firmly and infiltrating into the underlying tissue (Springer 1995). Selectins 
interact with glycoconjugated ligands on leukocytes to initiate this process (McEver 1995; 
Vestweber 1999). Transient adhesion mediated by selectins is a prerequisite for firm adhesion 
mediated by integrin receptors and subsequent transendothelial migration of leukocytes. Three 
selectins have been identified: P-, E- and L-selectin. P-selectin is the best characterized of the 
selectins and binding specificity and affinity to its physiological ligand P-selectin glycoprotein 
ligand-1 (PSGL-1) is well-documented (McEver 2004; Mehta 1998). P-selectin is stored in 
Weibel-Palade bodies in endothelial cells that line blood vessels and in α-granules in platelets. 
Extensive data have been published over the last decade that suggests a pivotal role for P- 
selectin in the pathophysiology of SCD (Matsui 2001). Much of this work has been conducted 
in mice engineered or altered to express human hemoglobin S (sickle cell hemoglobin) but not 
mouse β hemoglobin. These mice have a remarkably similar disease pathology and 
inflammatory profile to that observed in human SCD, including vaso-occlusion. Using these 
mice, investigators have demonstrated P-selectin interactions between the endothelium and 
sickled red blood cells, leukocytes, and platelets. Additional studies have demonstrated direct 
P-selectin-mediated binding of leukocytes with sickled red cells and platelets. All of these cell- 
cell interactions have been implicated in SCD vaso-occlusion. Further, blockade or genetic 
absence of P-selectin decreases or eliminates these cell-cell interactions and vaso-occlusion. 
Taken together, these studies establish P-selectin as a key mediator of vaso-occlusion in SCD.

Introduction to investigational treatment(s) and other study 
treatment(s) 
1.2.1 
Overview of Crizanlizumab (SEG101) 
Crizanlizumab (SEG101) is a humanized monoclonal antibody that binds P-selectin in humans 
and primates and blocks the interaction of P-selectin with its ligands. The compound was 
previously developed by Reprixys under the investigational drug code, SelG1, and subsequently 
became a legal entity of Novartis Pharmaceuticals on 18-Nov-2016. 
 
1.2.1.1 
Non-clinical experience 
Crizanlizumab is administered intravenously (i.v.) with instantaneous absorption and assumed 
100% bioavailability. As a humanized, monoclonal antibody, distribution is expected to be 
typical of endogenous human antibodies within the vascular and extracellular spaces by 
mechanisms dominated by convection, fluid-phase endocytosis, receptor-mediated endocytosis 
and their interaction with FcRn receptors (Heegaard 2002). Crizanlizumab contains only 
naturally occurring amino acids and has no known active metabolites. Human antibodies are

Amended Protocol Version 01 Clean

predominately catabolized by lysosomal enzymes to small peptides and amino acids. The extent 
of catabolism is inversely proportional to FcRn receptor affinity (Dall’Acqua et al. 2002). 
No specific studies have been conducted to evaluate specific pathways of crizanlizumab 
excretion. Due to its predicted molecular size of approximately 148 kDa, it is expected that 
crizanlizumab, like other immunoglobulins, is not eliminated by efficient filtration through the 
glomerulus in kidneys. 
In addition to studies in rodents containing human sickled hemoglobin, other studies 
demonstrated that human sickled red cells adhere to human endothelial cells more frequently 
than normal red cells, and an anti-human P-selectin antibody inhibits this adherence (Matsui et 
al. 2001). 
In experiments performed with the parental anti-human P-selectin antibody G1, the following 
data were generated: 1) G1 blocks the binding of human P-selectin to its ligand PSGL-1 (Geng 
et al. 1990) 2) G1 blocks leukocyte rolling and firm adhesion to human vascular endothelium 
under shear stress (Geng et al. 1990; Jones et al. 1993); 3) G1 effectively inhibits the interaction 
of neutrophils with stimulated platelets (Hamburger 1990); 4) G1 completely blocks the binding 
of human sickled red cells to human endothelium under flow (Wagner 2006); and 5) in mice 
expressing human but not mouse P-selectin, G1 blocks the rolling and adherence of leukocytes 
on mouse venules and can reverse pre-established leukocyte adhesion (Liu et al. 2010). 
In experiments performed to confirm that the humanized form of G1 (SelG1) shares identical 
specificity and function with parental G1, SelG1 was shown to 1) bind P-selectin with an near 
identical affinity to that of G1; 2) maintain the same species restriction pattern as G1; 3) have 
the same epitope recognition pattern as G1; 4) effectively block the binding of P-selectin to its 
receptor on human cells and; 5) retain the receptor/ligand dissociative property of G1. 
Due to the species restriction of SelG1 binding, much of the data available to date have been 
obtained from rodent modeling using mice expressing human hemoglobin S (sickle cell 
hemoglobin) with surrogate antibodies that block mouse P-selectin or animals genetically 
deficient in P-selectin. Where possible, the SelG1 parental antibody G1 has been used in 
experimentation in which human P-selectin is present. In addition, confirmatory data with 
SelG1 were established. 
In mice expressing human sickled hemoglobin (human βS mice) the following data were 
generated: 1) an anti-mouse P-selectin antibody blocks leukocyte rolling (Kaul 2000); 2) vaso- 
occlusion is blocked in animals deficient in P-selectin (Frenette 2004); 3) platelet and leukocyte 
adhesion to vascular endothelium is absent in P-selectin deficient animals (Wood 2004); and 4) 
sickled red cell microvascular flow is increased and vaso-occlusion decreased with an anti- 
mouse P-selectin antibody (Embury et al. 2004). 
Finally, SelG1 has been administered to nonhuman primates in a single-dose and two separate 
GLP multi-dose studies. Administration of SelG1 by bolus IV injection once every 4 weeks to 
cynomolgus monkeys for a total of seven doses was well tolerated at doses ≤ 25 mg/kg/dose; 
the no observed adverse effect level (NOAEL) is therefore 25 mg/kg/dose. 
As SelG1 is specific to human and nonhuman primate P-selectin and in accordance with the ICH 
S6 Guidance, no genotoxicity or reproductive toxicology studies have been performed to date.

1.2.1.2 Clinical experience 
 
Phase I Clinical Study (CSEG101A2101) 
The objectives of this study (Reprixys study code: Se1G1-00003; Novartis study code: 
CSEG101A2101) were to evaluate the safety, PK, PD, and immunogenicity of intravenously 
administered SelG1 versus placebo in 27 healthy subjects at ascending dose levels (0.2, 0.5, 1.0, 
5.0 mg/kg and 8.0 mg/kg). 
Crizanlizumab concentrations slowly declined, with mean half-life ranging from 75.6 (at dose 
of 0.2 mg/kg) to 500 (at 5.0 mg/kg) hours. Therefore, clearance decreased with the increase in 
dose level: 88.6 mL/hr. (at 0.2 mg/kg) to 9.91 (at 5.0 mg/kg). Following two intravenous 
infusions of SelG1 at 8.0 mg/kg, the mean half-life was 363 hours, and the clearance was 3.86 
mL/hr. For subjects receiving a single dose of crizanlizumab at 5.0 mg/kg, P-selectin inhibition 
was complete for at least 28 days with a mean crizanlizumab concentration on Day 28 of 
19.9±3.8 μg/mL. 
There were no infection-related AEs, changes in coagulation parameters, increased bleeding 
tendencies, or notable treatment-related changes in peripheral blood immunophenotyping. The 
immunogenicity data generated during the Phase I clinical trial indicate that no specific antibody 
response to SelG1 occurred in any subjects receiving up to 2 doses of drug. 
Based on AEs, clinical laboratory evaluations, vital signs measurements, physical examinations, 
and ECG evaluations, administration of SelG1 was safe and well-tolerated in this group of 
healthy male and female subjects. 
 
Phase II Clinical Study (SUSTAIN – CSEG101A2201) 
The purpose of SUSTAIN (Reprixys study code: Se1G1-00005; Novartis study code: 
CSEG101A2201) study was to investigate the safety and tolerability of the humanized anti-P- 
selectin monoclonal antibody, crizanlizumab (SelG1), during chronic administration to SCD 
patients and to investigate the efficacy of crizanlizumab to affect the rate of sickle cell-related 
pain crises (SCPC) (also known as VOC leading to a healthcare visit) as well as a variety of 
other 
clinical 
endpoints, 
anemia- 
and 
hemolysis-related 
laboratory 
parameters, 
pharmacokinetics/pharmacodynamics (PK/PD), and patient reported outcomes. 
This trial was a multicenter, randomized, placebo-controlled, double-blind, parallel-group study 
to assess the safety and efficacy of crizanlizumab versus placebo in patients with SCD, both 
receiving and not receiving HU/HC. Crizanlizumab was administered at 2 different dose levels 
(2.5 mg/kg and 5.0 mg/kg). A total of 198 patients were randomized and included in the intent- 
to-treat (ITT) population, with 67 patients randomized to receive crizanlizumab at 5.0 mg/kg 
(5.0 mg/kg treatment arm), 66 patients to receive crizanlizumab at 2.5 mg/kg (2.5 mg/kg 
treatment arm), and 65 patients to receive placebo (placebo treatment arm). 
The primary efficacy parameter was the assessment of the annual rate of VOC leading to a 
healthcare visit, defined as an acute episode of pain, for which there is with no other medically 
determined explanation cause than a vaso-occlusive event, which requires a medical facility 
(clinic, emergency room (ER), or hospital) visit and treatment with oral or parenteral narcotics, 
or parenteral non-steroidal anti-inflammatory drugs. Acute chest syndrome, hepatic 
sequestration, splenic sequestration and priapism events requiring a visit to a medical facility

were also considered VOC leading to a healthcare visit for analysis purposes. It was observed 
that treatment with 5.0 mg/kg crizanlizumab resulted in an annual rate of VOC leading to a 
healthcare visit that was 45.3% lower than the rate with placebo which was statistically 
significant (p = 0.010). The annual rate of VOC leading to a healthcare visit in the 2.5 mg/kg 
crizanlizumab treatment arm was compared with that of placebo, and although favorable (32.6% 
reduction with active treatment), it was not statistically significant (p = 0.180). In addition, in 
the 5.0 mg/kg crizanlizumab arm, numerical and clinically significant reductions in the annual 
rate of VOC leading to a healthcare visit were observed across important subgroups, including 
patients receiving concomitant HU (32.1%) and not receiving concomitant HU (50.0%), and in 
patients with the HbSS genotype (34.6%) and non-HbSS genotype (50.5%) (HbSC, HbSβ0- 
thalassemia, HbSβ+-thalassemia, and others). The median annual rate of days hospitalized was 
numerically reduced in the 5.0 mg/kg arm versus the placebo arm (4.00 versus 6.87, 
respectively); however this difference was not statistically significant. Treatment with 
crizanlizumab at 5.0 mg/kg was associated with longer median time to first VOC leading to a 
healthcare visit compared with placebo (4.07 versus 1.38 months, p = 0.001) and median time  
to second VOC leading to a healthcare visit compared to placebo (10.32 versus 5.09 months, p 
= 0.022). 
Crizanlizumab was well tolerated. Adverse events that occurred in ≥5% of patients in an active 
dose group and were more than 2 times higher than placebo were: arthralgia, pruritus, vomiting, 
chest pain, diarrhea, fatigue, myalgia, musculoskeletal chest pain, abdominal pain, influenza 
and oropharyngeal pain. There were 5 deaths during the study (2 at 5.0 mg/kg, 1 at 2.5 mg/kg 
and 2 in the placebo group), and no deaths were deemed related to study drug. The proportion 
of subjects experiencing SAEs was 25.8% at 5.0 mg/kg, 32.8% at 2.5 mg/kg and 27.4% in the 
placebo group. Adverse events that occurred in 10% or more of the patients in either active 
treatment group and at a frequency that was at least twice as high as that in the placebo group 
were arthralgia (5.0 mg/kg: 18.2% versus 2.5 mg/kg: 14.1% versus placebo: 8.1%), diarrhea 
(10.6% versus 7.8% versus 3.2%), pruritus (7.6% versus 10.9% versus 3.4%), vomiting (7.6% 
versus 10.9% versus 4.8%) and chest pain (1.5% versus 10.9% versus 1.6%). No patient 
developed anti-drug antibodies (ADA) against crizanlizumab during the course of the 
SUSTAIN study. 
A sub analysis of risk ratio (RR [95% confidence intervals]; p-value) of infections found no 
evidence of association between crizanlizumab and infections. For this analysis, two subgroups 
were analyzed: infections and serious infections. The results show for infections a RR of 1.03 
[0.82-1.29]: p=0.819; and for serious infections a RR of 1.07 [0.58-1.97]: p=0.820. The results 
suggest that the risk of infections and serious infections in crizanlizumab and placebo groups 
was similar. 
Overall, treatment of patients with SCD with crizanlizumab at 5.0 mg/kg showed positive 
clinical activity as demonstrated by a decrease in the annual VOC leading to a healthcare visit 
rate compared with placebo. Treatment with crizanlizumab at 5.0 mg/kg was also found to be 
well tolerated.

Rationale 
2.1 
Study rationale and purpose 
Clinical and toxicological studies performed to date for crizanlizumab were conducted using 
Reprixys material (SelG1 mAb). To ensure supply of future clinical studies as well as 
commercial demand, Novartis has optimized the production of crizanlizumab. The Novartis 
material (SEG101 mAb) drug substance (DS) and drug product (DP) will be manufactured at 
Novartis sites. In vitro characterization and primate PK experiments conducted with both mAbs 
did not reveal significant differences that would influence PK/PD results. Therefore, the change 
in cell line is not expected to impact the bioavailability or activity of the compound. The 
CSEG101A2202 study will be the first trial to administer crizanlizumab to SCD adult patients. 
The purpose of this study is to characterize the PK and PD of crizanlizumab and to evaluate the 
safety and efficacy of crizanlizumab in SCD patients. 
 
2.2 
Rationale for the study design 
Study CSEG101A2202 is designed as a Phase II, multicenter, open-label study. The first 45 
patients (to identify 27 evaluable patients) will be enrolled to the treatment group crizanlizumab 
5.0 mg/kg to complete full PK and PD sampling at week 1 and week 15. In all patients, pre- 
dose PK and PD samples will also be collected prior to each dose.
 
 
 Once the first 45 
patients are enrolled, 10 additional patients will be enrolled to the exploratory treatment group 
and begin at 7.5 mg/kg of crizanlizumab. 
The patients will undergo a screening period from Day -35 to Day -1 in order to enable the 
study center to conduct the required tests for eligibility. The first 45 patients will be enrolled to 
receive infusion doses of crizanlizumab 5.0 mg/kg (test) on the first day (Week 1 Day 1), Week 
3 Day 1, and then day 1 of every 4-week cycle. No dose reductions are allowed in the study for 
patients assigned to 5.0 mg/kg dose. Patients will continue on study until 105 days after 
discontinuing drug or until receiving crizanlizumab commercially or through a different study 
or access program. Patients may need to stay at the study center for at least 24 hours following 
the first drug administration during which time blood samples for measurement of 
crizanlizumab will be collected, and then after the fifth dose (Week 15 Day 1). Patients will be 
discharged from the study site on Day 2 of Week 1 and Day 2 of Week 15 and will return on 
Week 1 Day 4, Week 2 Day 1, Week 3 Day 1, Week 7 Day 1, Week 11 Day 1, Week 15 Day 1 
(patients to stay at study site for 24 hours as described above), Week 15 Day 4, Week 16 Day 
1, Week 17 Day 1, Week 19 Day 1, and Day 1 of every 4 weeks for ambulatory visit for 
additional pharmacokinetic/pharmacodynamics and immunogenicity assessments and at 105 
days after the last dose for the safety follow-up visit. 
After 45 patients are enrolled at the 5.0 mg/kg dose, up to 10 additional patients (to identify 6 
evaluable patients) will be enrolled to the exploratory treatment group of 7.5 mg/kg 
crizanlizumab.
 
The 10 patients will receive 
infusion doses of crizanlizumab at 7.5 mg/kg on the same schedule and with the same 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 25
0 Protocol No. 
 
 
administration requirements as for the 5.0 mg/kg group. 
 
 
 
 
 
 
2.3 
Rationale for dose and regimen selection 
Patients will receive crizanlizumab at a dose of 5.0 or 7.5 mg/kg by IV infusion over 30 minutes. 
Dose number 2 is administered as a loading dose 2 weeks following the first dose to rapidly 
achieve steady-state serum concentrations. This is followed by repeated administration of the 
initial dose every 4-weeks ± 3 days to ensure that steady-state serum concentrations of 
crizanlizumab are maintained to provide a consistent blockade of P-selectin throughout the 
study. 
The SUSTAIN trial tested either 5.0 mg/kg or 2.5 mg/kg of SelG1 on this same dosing schedule 
and showed a statistically significant reduction in median annual rate of VOC leading to a 
healthcare visit in the 5.0 mg/kg dose group versus placebo, while the 2.5 mg/kg group did not 
have a statistically significant reduction. The overall safety was well-balanced across treatment 
and placebo groups (5.0 mg/kg: 86% AE and 26% SAE – 2.5 mg/kg: 88% AE and 33% SAE – 
placebo: 89% AE and 27% SAE) (Ataga 2016). The doses chosen for the SUSTAIN study were 
based on complete P-selectin inhibition of SelG1 in healthy subjects, as well as the acceptable 
safety experience observed with 5.0 mg/kg and 8.0 mg/kg dosing regimens during the Phase I 
safety study. As mentioned in Section 1.2.1.2, the phase I study (CSEG101A2101) found that 
a single dose of SelG1 at 5.0 mg/kg yielded at least 28 days of complete P-selectin inhibition.

Risks and benefits 
Overall, treatment of SCD patients with crizanlizumab at 5.0 mg/kg demonstrated statistically 
significant, clinically meaningful, and robust efficacy results vs. placebo in reduction of annual 
rate of sickle cell-related pain crisis (SCPC) (also known as VOC leading to a healthcare visit) 
and delay of onset of VOC leading to a healthcare visit in a well-controlled Phase II clinical 
trial (SUSTAIN study) in a clearly defined SCD patient population. Treatment with 
crizanlizumab at 5.0 mg/kg was also found to be well tolerated 
 
 
 The substantial efficacy and acceptable safety 
of crizanlizumab suggest an overall favorable benefit-risk assessment and warrant further 
clinical development in SCD. 

Novartis 
Amended Protocol Version 01 Clean 
Confidential

Crizanlizumab was well tolerated in SUSTAIN study. There were no unexpected safety findings; 
however, infusion-related reactions were observed in around 2% of subjects. 
The risk of infections and serious infections with the use of crizanlizumab has been evaluated 
and the results suggest that the risk of infections and serious infections in crizanlizumab and 
placebo groups was similar. 
Monoclonal antibodies (mAbs) are large molecules intended to bind to specific targets often 
expressed on the immune system, and to treat various immunopathological conditions. 
Therefore, mAbs can be considered to have a high potential for immunotoxicity, which is 
reflected in the clinical experience accumulated on mAbs-induced adverse effects related to 
immunosuppression, immunostimulation and hypersensitivity (immunogenicity) (Descotes J, 
2009). So far, clinical studies have shown no deleterious effects of the use of crizanlizumab in 
regards to immunotoxicity and immunogenicity. 
Appropriate eligibility criteria and stopping rules are included in this protocol. Recommended 
guidelines for prophylactic or supportive management of study-drug induced adverse events are 
provided in Section 6.4. The risk to subjects in this trial may be minimized by compliance with 
the eligibility criteria and study procedures, as well as, close clinical monitoring, and in-patient 
status for 24 hours following the first dose. There may be unforeseen risks with crizanlizumab, 
which could be serious. For additional safety information, refer to the latest Investigator’s 
Brochure.

Study design 
4.1 
Description of study design 
This is a multicenter, single-arm, open-label study to assess PK and PD of crizanlizumab in 
adult patients with SCD and VOC. 
Approximately 55 patients will be enrolled in the trial. 45 eligible patients (all screening criteria 
met) will be treated with crizanlizumab at a dose of 5.0 mg/kg and up to 10 additional eligible 
patients (all screening criteria met) will be treated with crizanlizumab at a dose of 7.5 mg/kg. 
The study will include adult patients, ages 16-70 years, with confirmed diagnosis of SCD 
(genotypes HbSS, HbSC, HbS β0-thalassemia, HbS β+-thalassemia, and others) who have 
experienced at least 1 VOC within the preceding 12 months. Patients may not plan to initiate 
HU/HC during the study. For patients who are already treated with HU/HC, they should be 
taking HU/HC for at least 6 months and plan to continue the same dose at the same schedule 
during the trial 
Patients will receive treatment until study treatment is permanently discontinued due to 
unacceptable toxicity, death, are lost to follow-up or discontinued from the study treatment for 
any other reasons. Patients will be followed in the mandatory safety follow-up period until 105 
days after the last dosing. Patients continuing to receive benefit, defined as no evidence of 
increased frequency of VOCs and no severe adverse events attributed to drug as per 
Investigator’s assessment, will remain on study until crizanlizumab is commercially available 
or until patients are rolled over in a different crizanlizumab study or access program. 
 
Screening phase 
Within 35 days before enrolment, the patient will provide a main signed informed consent form 
prior to any study related activities. All screening evaluations must be performed during the 
screening period (day-35 to day-1). 
 
Treatment phase 
Once eligibility criteria have been confirmed to Novartis via the eligibility checklist, the patient 
will be enrolled in the trial and will receive crizanlizumab. Study treatment should be started as 
soon as possible. 
Patients may be admitted to the study site prior to dosing for baseline evaluations. The first 45 
patients will receive crizanlizumab 5.0 mg/kg by IV infusion over 30 min on week 1 day 1, 
week 3 day 1, and then day 1 of every 4-week cycle. No dose change or modification will be 
allowed in the study for patients assigned to 5.0 mg/kg dose. Once 27 patients have evaluable 
PK/PD data (or a total of 45 patients are enrolled) at the 5.0 mg/kg dose, an exploratory cohort 
of 10 patients will be enrolled at a dose of 7.5 mg/kg. Patients will receive crizanlizumab 7.5 
mg/kg by IV infusion over 30 min on week 1 day 1, week 3 day 1, and then day 1 of every 4- 
week cycle. Dose change or modifications are described in the Section 6.3. 
All enrolled patients will have PK/PD sampling performed in order to characterize the PK/PD 
of crizanlizumab (see Table 7-5). On week 1 day 1 and week 15 day 1 the patients may be asked 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 30
9 Protocol No. 
 
 
to remain at the study site for at least 24 hours post dose in order to complete the PK/PD sample 
collection. 
In case of VOC, the related medical and treatment information will be collected. 
 
 
 
Safety will be monitored as outlined in Section 8. Patients will receive treatment until 
unacceptable toxicity, death, are lost to follow-up or discontinued from the study treatment for 
any other reasons. 
 
Post-treatment follow-up phase 
After the end of treatment visit, all patients will be followed up for safety up to 105 days (15 
weeks) after the last dose of study treatment.

4.2 
Timing of interim analyses and design adaptations 
Exploration of early access (EA) PK data may occur for preliminary PK analysis prior to clinical 
data base lock. PK samples may be batched and shipped for expedited EA PK analysis and data 
will be uploaded by the bioanalyst via PKLink. For the derivation of PK parameters nominal 
time instead of actual elapsed time may be used. 
An interim analysis may be performed when there are at least 27 patients with single dose 
evaluable PK profiles and approximately 5 patients with both single dose and multiple dose 
evaluable PK profiles in the 5.0 mg/kg treatment group in the Pharmacokinetic Analysis Set 1 
(PAS1). This interim analysis may further characterize the PK/PD profile for the pediatric study 
CSEG101B2201; however there is currently no plan for design adaptation of trial 
CSEG101A2202. Another interim analysis may be performed when there are approximately 15 
patients with multiple dose evaluable PK profiles in the 5.0 mg/kg treatment group in the PAS1, 
in order to inform the PK/PD/safety profile of crizanlizumab and potentially support the 
regulatory filing. Should the criteria for the two interim analyses be reached at similar times 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 31
9 Protocol No. 
 
 
compatible with both objectives, a single combined interim analysis will be performed. 
Additional earlier or later ad hoc interim analyses of PK/PD/safety may be performed in order 
to support potential Health Authority requests. 
 
4.3 
Definition of end of study 
The primary analysis will be conducted after the PK and PD parameters are available for at least 
27 patients in the 5.0 mg/kg treatment group in the Pharmacokinetic Analysis Set 1 (PAS1) and 
Pharmacodynamics Analysis Set 1 (PDS1) respectively. The primary analysis data will be 
summarized in the primary clinical study report (CSR). 
Following the cut-off date for the analysis reported in the primary CSR, the study will remain 
open. Ongoing patients will continue to receive study treatment and be followed as per the 
schedule of assessments, as long as patients derive benefit from crizanlizumab. The end of study 
is defined by the occurrence of one of the following: 
• All patients have died or discontinued from the study 
• Crizanlizumab is commercially available for this patient population, and patients obtain 
the commercial drug 
• Another clinical study becomes available that can continue to provide crizanlizumab in 
this patient population and all patients ongoing are transferred to that clinical study 
The final analysis will occur at the end of the study. All available data from all patients up to 
the trial end will be analyzed and summarized in a final CSR. 
 
4.4 
Early study termination 
The study can be terminated at any time for any reason by Novartis. Should this be necessary, 
the patient should be seen as soon as possible and the same assessments should be performed 
as described in Section 7 for a discontinued or withdrawn patient. 
Premature study termination must occur if one or more of the following reasons apply: 
• Decision of the Sponsor 
• Safety issues: If more than 25% of the subjects at any time point have been withdrawn due 
to adverse events or abnormal laboratory results and abnormal test procedure results 
related to the study drugs. 
• If information becomes available that the use of crizanlizumab would expose the subjects 
to an unacceptable risk. 
In the event the safety stopping criteria are met, the Sponsor and Principal Investigator will 
discuss the implications of study continuation. 
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 patient’s interests. The investigator 
will be responsible for informing IRBs and/or ECs of the early termination of the trial.

Treatment 
6.1 
Study treatment 
Novartis will supply crizanlizumab (SEG101) as an open label medication. The investigational 
drug will be the crizanlizumab - SEG101 Histidine/Citrate buffered solution – provided every 
4 weeks with an additional loading dose 2 weeks after the first dosing (i.e. dosing on first day 
of week1, week3, week7, and then every 4 weeks) until the end of study.

Crizanlizumab is provided in single use vials containing 10 mL at a concentration of 10 mg/mL. 
The crizanlizumab formulation is a Histidine/Citrate buffered solution which is supplied in 
single use vials at a concentration of 10 mg/mL. 
Each patient receives one dose of crizanlizumab on Week 1 Day 1, Week 3 Day 1, Week 7 Day 
1 and day 1 of every 4-week cycle. On infusion day, the pharmacist or designated personnel 
will compound individual doses of crizanlizumab for patients on a milligram per kilogram basis 
in a 100 mL infusion bag of a sterile 0.9% sodium chloride solution (0.9% Sodium Chloride 
Injection, USP) in accordance with the Pharmacy Manual. Study drug will be administered over 
30 minutes by IV infusion. 
After the primary analysis, and considering that the drug product development is still ongoing 
to provide robust shelf-life, crizanlizumab Histidine/Citrate buffered solution may be substitute 
by the Final Market Image (FMI), citrate buffered solution. Minor modifications in the final 
buffer composition are expected and will be covered by in-vitro comparability studies.

For patients who do not tolerate the protocol-specified dosing schedule, dose interruptions 
and/or reductions are either recommended or mandated in order to allow patients to continue 
the study treatment until the next dose scheduled. Dose reductions are only allowed for 
patients assigned to 7.5 mg/kg dose. No dose reductions are allowed in the study for 
patients assigned to 5.0 mg/kg dose who just have option for dose interruption. The dose 
reduction is only in one level: from 7.5 mg/kg to 5.0 mg/kg and it is recommended at the grade 
2 or 3 or higher for the CTCAE or otherwise mentioned in Table 6-2 and Table 6-3. If drug- 
induced toxicities are present, patients would have to be closely monitored and a decision to 
continue or discontinue the patient from the study would have to be done at the next dose 
scheduled. 
These dose interruptions / reductions are summarized in Table 6-4. Deviations to mandatory 
dose interruptions are not allowed. Permanent treatment discontinuation is mandatory for 
specific events indicated as such in Table 6-4 or listed in Section 7.1.5.1. 
Missing 2 consecutive doses (no dose for 10 weeks) would be considered criteria for 
permanently discontinuing the patient from the study. 
Any dose changes must be recorded on the Dosage Administration Record CRF.

a Common Toxicity Criteria for Adverse Events (CTCAE Version 4.03) 
b Core LFTs consist of ALT, AST, GGT, total bilirubin (fractionated [direct and indirect], if total bilirubin > 2.0 x ULN), and alkaline phosphatase 
(fractionated [quantification of isoforms], if alkaline phosphatase > 2.0 x ULN.) 
c “Combined” defined as total bilirubin increase to the defined threshold concurrently with ALT/AST increase to the defined threshold 
If combined elevations of AST or ALT and total bilirubin do not meet the defined thresholds, please follow the instructions for isolated elevation of total 
bilirubin and isolated elevation of AST/ALT, and take a conservative action based on the degree of the elevations (e.g. discontinue treatment at the 
situation when omit dose is needed for one parameter and discontinue treatment is required for another parameter). After all elevations resolve to the 
defined thresholds that allow treatment re-initiation, re-start the treatment either at the same dose or at one dose lower if meeting a criterion for dose 
reduction. Dose reductions are only allowed for patients assigned to 7.5 mg/kg dose. No dose reductions are allowed in the study for patients 
assigned to 5.0 mg/kg dose. 
d “Cholestasis” defined as ALP elevation (>2.0 x ULN and R value <2 ) in patients without bone metastasis, or elevation of ALP liver fraction in patients 
with bone metastasis 
Note: The R value is calculated by dividing the ALT by the ALP, using multiples of the ULN for both values. It denotes whether the relative pattern of 
ALT and/or ALP elevation is due to cholestatic (R ≤ 2), hepatocellular ( R ≥ 5), or mixed (R >2 and < 5) liver injury

Grade 2 
Stop infusion 
Before restarting - administer oral premedication (e.g.1000 mg of 
acetaminophen/paracetamol, 50-100 mg diphenhydramine hydrochloride 
or alternative antihistamine), within 60 minutes of restarting the infusion. 
Restart infusion at 50% of previous rate under continuous observation. 
Ensure that there is a minimum observation period of 1 hour prior to 
restarting the infusion(s). 
If the AE recurs at the reinitiated slow rate of infusion, and despite oral 
pre-medication, then discontinue patient from study. 
Grade 3 and 4 
Discontinue study treatment 
 
6.3.1.1 
Follow up on potential drug-induced liver injury (DILI) cases 
Patients with transaminase increase combined with TBIL increase may be indicative of 
potential DILI, and should be considered as clinically important events. 
The threshold for potential DILI may depend on the patient’s baseline AST/ALT and TBIL 
value; patients meeting any of the following criteria will require further follow-up as outlined 
below: 
• For patients with normal ALT and AST and TBIL value at baseline: AST or ALT > 3.0 x 
ULN combined with TBIL > 2.0 x ULN 
• For patients with elevated AST or ALT or TBIL value at baseline: [AST or ALT > 2 x 
baseline AND > 3.0 x ULN] OR [AST or ALT > 8.0 x ULN], combined with [TBIL > 2 x 
baseline AND > 2.0 x ULN] 
Medical review needs to ensure that liver test elevations are not caused by cholestasis, defined 
as ALP elevation > 2.0 x ULN with R value < 2 in patients without bone metastasis, or elevation 
of ALP liver fraction in patients with bone metastasis. 
Monitoring for hemolysis in subjects with elevations of TBIL > 2.0 x ULN should be performed 
to rule out a plausible explanation of increase of TBIL. 
Note: (The R value is calculated by dividing the ALT by the ALP, using multiples of the ULN 
for both values. It denotes whether the relative pattern of ALT and/or ALP elevation is due to 
cholestatic (R ≤ 2), hepatocellular (R ≥ 5), or mixed (R >2 and < 5) liver injury). 
In the absence of cholestasis, these patients should be immediately discontinued from study 
drug treatment, and repeat LFT testing as soon as possible, preferably within 48 hours from the 
awareness of the abnormal results. The evaluation should include laboratory tests, detailed 
history, physical assessment and the possibility of liver metastasis or new liver lesions, 
obstructions/compressions, etc.

1. Laboratory tests should include ALT, AST, albumin, creatine kinase, total bilirubin, direct 
and indirect bilirubin, GGT, prothrombin time (PT)/INR and alkaline phosphatase. 
2. A detailed history, including relevant information, such as review of ethanol, concomitant 
medications, herbal remedies, supplement consumption, history of any pre-existing liver 
conditions or risk factors, should be collected. 
3. Further testing for acute hepatitis A, B, C or E infection and liver imaging (e.g. biliary 
tract) may be warranted. 
4. Obtain PK sample, as close as possible to last dose of study drug. 
5. Additional testing for other hepatotropic viral infection (CMV, EBV or HSV), 
autoimmune hepatitis or liver biopsy may be considered as clinically indicated or after 
consultation with specialist/hepatologist. 
6. If elevations of total bilirubin precede the elevations of ALT and or AST, monitoring for 
hemolysis. 
All cases confirmed on repeat testing meeting the laboratory criteria defined above, with no 
other alternative cause for LFT abnormalities identified should be considered as “medically 
significant”, thus, met the definition of SAE (Section 8.2.1) and reported as SAE using the term 
“potential drug-induced liver injury”. All events should be followed up with the outcome clearly 
documented. 
 
6.3.1.2 
Dose adjustments for QTcF prolongation 
In case of QTcF >500 msec, (or QTcF prolongation >60 msec from baseline) 
1. Assess the quality of the ECG recording and the QT value and repeat if needed 
2. Interrupt study treatment 
3. Determine the serum electrolyte levels (in particular hypokalemia, hypomagnesemia). If 
abnormal, correct abnormalities before resuming study drug treatment. 
4. Review concomitant medication associated with QT prolongation, including drugs with a 
“Known”, “Possible”, or “Conditional risk of Torsades de Pointes” and drugs with the 
potential to increase the risk of study drug exposure related QT prolongation (See 
Appendix 2) 
5. Check study drug dosing schedule and treatment compliance 
6. Consider collecting a time-matched PK sample and record time and date of last study drug 
intake. 
After confirming ECG reading at site, if QTcF > 500 msec (or QTcF prolongation >60 
msec from baseline) 
• Interrupt study treatment 
• Repeat ECG and confirm ECG diagnosis by a cardiologist or central ECG lab 
• If QTcF confirmed > 500 msec: 
• Correct electrolytes, eliminate culprit concomitant treatments, and identify and 
address clinical conditions that could potentially prolong the QT. 
• Consult with a cardiologist (or qualified specialist) 
• Increase cardiac monitoring as indicated, until the QTcF returns to ≤ 480 msec. 

Novartis 
Amended Protocol Version 01 Clean

• After resolution to ≤ 480 msec, consider re-introducing treatment at reduced dose (for 7.5 
mg/kg only), and increase ECG monitoring for the next treatment(s): 
• If QTcF remains ≤ 500 msec after dose reduction, continue planned ECG monitoring 
during subsequent treatment 
• If QTcF recurs > 500 msec after dose reduction, discontinue patient from trial. 
6.4 
Concomitant medications 
In general, the use of any concomitant medication/therapies deemed necessary for the care of 
the patient is permitted (see Section 6.4.1), except as specifically prohibited (see Section 6.4.2). 
The patient must be told to notify the investigational site about any new medications he/she 
takes within 30 days prior to initial dosing until the completion of end of study (EOS) visit 
(through 105 days after the last dose of study treatment). All medications (including prescription 
drugs, herbal medications/supplements, over the counter (OTC) medication, dietary and vitamin 
supplements) and significant non-drug therapies (including physical therapy and blood 
transfusions) taken or administered within the timeframe defined in the entry criteria until 
completion of the EOS visit must be listed on the Prior and Concomitant medications, Surgical 
and Medical Procedures or Transfusion page of the CRF. 
 
6.4.1 
Permitted concomitant therapy 
Concomitant sickle cell therapy with hydroxyurea or hydroxycarbamide is permitted, provided 
the patient has been prescribed HU/HC consistently over at least the 6 months prior to 
enrollment, as stated in the Inclusion criteria. Erythropoietin-stimulating agents are also 
permitted to manage chronic symptomatic anemia with the same requirement for 6 months prior 
therapy as HU/HC. L-glutamine oral powder (Endari) is also permitted without restriction. 
Aspirin, NSAIDs and prophylactic doses of anticoagulants are permitted, while other anti- 
platelets agents or anticoagulants at doses targeting therapeutic levels are prohibited. 
All FDA-approved forms of analgesia for pain are permitted per standard of care. Other 
approved medications for supportive care (antiemetics, anxiolytics, hypnotics, antihistamines) 
are permitted, including marinol. 
 
6.4.2 
Permitted concomitant therapy requiring caution and/or action 
Although transfusion of cellular blood products is permitted, it is unclear how such transfusions 
will impact the PK and/or PD of crizanlizumab, 
 
 It should also be 
considered that the administration of products containing immunoglobulins (plasma, IVIG, 
anti-globulins) may also impact the efficacy of crizanlizumab, and optional PK and PD testing 
may also be performed prior to and following administration of such therapies. 
Although Endari, the FDA-approved, version of L-glutamine, is permitted, other over-the- 
counter forms of L-glutamine are discouraged, as are other natural and herbal remedies (e.g. 
EvenFlo and/or products containing dang gui, ligustrum root, ginseng root, white peony, 
corydalis, salvia, copodonosis, poria, jujbe, angelica sinensis, lovage) due the unproven efficacy 
and variable quality and composition of these products. Vitamin and mineral supplements (e.g. 
fish oil, folic acid, L-arginine, L-citrulline, magnesium, riboflavin, vitamin C, vitamin D, 

Novartis 
Amended Protocol Version 01 Clean

vitamin E, and Zinc) are also permitted, though caution is advised when taking amounts 
exceeding 100% of the recommended daily allowance. 
 
6.4.3 
Prohibited concomitant therapy 
As far as possible avoid co-administering drugs with a “Known”, “Possible”, or “Conditional” 
risk of Torsades de Pointes (TdP) as per wwwqtdrugsorg during the course of the study: 
• If concomitant administration of drugs with a “Known risk of Torsades de Pointes” is 
required and cannot be avoided, study drug must be interrupted. Study treatment may only 
be resumed after 5 half-lives (of the QT-prolonging drug) from last dose of the QT 
prolonging drug, and close ECG monitoring is advised. 
• If during the course of the study, concomitant administration of a drug with ¨Possible risk¨ 
or ¨Conditional risk of Torsades de Pointes¨ is required, based on the investigator 
assessment and clinical need, study treatment may be continued under close ECG 
monitoring to ensure patient safety. 
A list of drugs associated with QT prolongation and/or TdP is available online at 
wwwqtdrugsorg. 
The use of other investigational agents is prohibited during the study. In addition, the 
administration of monoclonal antibodies other than crizanlizumab is prohibited, due to the 
theoretical potential for cross-reactivity and/or overlapping toxicities with other monoclonal 
antibodies. If investigational agents or other monoclonal antibodies have been used in the past, 
they must have been discontinued at least 30 days (or 5 half-lives of that agent, whichever is 
greater) prior to Screening. 
Infusion-type reactions were rarely reported in prior studies with crizanlizumab, so prophylaxis 
for such reactions is not recommended. If a patient experiences severe infusion-related reaction, 
study drug should be discontinued and appropriate treatment provided.

Subject numbering, treatment assignment or enrolment 
6.5.1 
Subject numbering 
Each patient is identified in the study by a Subject Number (Subject No.) (7 digits), that is 
assigned when the patient is first enrolled for screening and is retained as the primary identifier 
for the patient throughout his/her entire participation in the trial. The Subject No. consists of 
the Center Number (Center No. 4 digits) (as assigned by Novartis to the investigative site) with 
a sequential patient number suffixed to it (3 digits), so that each patient is numbered uniquely 
across the entire database. Upon signing the informed consent form, the patient is assigned to 
the next sequential Subject No. available to the investigator through the Clinical Data 
Management System interface.

Treatment assignment or Enrolment 
The first 45 patients will be assigned to the 5.0 mg/kg crizanlizumab treatment, while the 10 
next enrolled patients will be assigned to the 7.5 mg/kg crizanlizumab treatment (Section 4.1 
and Section 6.1). The assignment of a patient to a particular treatment dose will be confirmed 
by the sponsor based on the actual enrolment. 
 
6.5.3 
Treatment blinding 
This is an open label study. Investigators, patients and Sponsor will have full knowledge of the 
treatment allocation. In order to minimize the potential impact of the treatment knowledge, until 
the primary analysis is conducted, no aggregated statistical analyses (efficacy or safety across 
the study) shall be performed by treatment (other than analyses as specified in the study 
protocol). 
 
6.6 
Study drug preparation and dispensation 
Crizanlizumab will be prepared by a pharmacist or study personnel appropriately trained in the 
preparation of liquids for parenteral administration (use aseptic techniques when preparing the 
study drug solution). Only compatible material tested during compatibility should be used for 
the administration of crizanlizumab. 
Prior to administration, the crizanlizumab admixture should be allowed to warm to room 
temperature by exposure to ambient air. Do not heat thecrizanlizumab admixture in a 
microwave or with any heat source other than ambient air temperature. The crizanlizumab 
study drug product should only be administered via IV infusion including a 0.2μm inline filter 
and must be diluted prior to administration. 
NOTE: DO NOT ADMINISTER THE STUDY DRUG AS AN IV PUSH OR BOLUS 
INJECTION. After administration of study drug (5.0 mg/kg crizanlizumab or 7.5 mg/kg 
crizanlizumab), a 25 mL flush of the IV line will occur. Site personnel should ensure availability 
of at least 25 mL of sterile 0.9% sodium chloride solution (0.9% Sodium Chloride Injection, 
USP) for administration after that of study drug. 
Prepared infusion solution in infusion bag should be used immediately, and must be within 4 
hours of preparation. 
If the selected center for the clinical study is located in US and is USP<797> compliant, the 
preparation and handling of the infusion bags shall comply with the guidance given in the USP 
but is limited to the physico-chemical stability demonstrated as indicated below. 
If the selected center for the clinical study is located in US and is NOT USP<797> compliant, 
from a microbiologic point of view, the ready mixed infusion bag shall be used immediately 
and not be held for longer than four hours at room temperature from the moment the first vial 
is pierced till the start of administration. 
The compounded 0.9% sodium chloride (saline) bag with crizanlizumab should be 
intravenously administered over 30 minutes. It is not necessary to protect the infusion bags from 
light (still direct sun light should be avoided) while study drug is being administered to the 
patient. At the site’s discretion, the crizanlizumab saline bag may be administered via gravity 
feed, a syringe-type pump, or an infusion pump. Following completion of the study drug 

Novartis 
Amended Protocol Version 01 Clean

infusion, at least another 25 mL 0.9% sodium chloride should be administered in order to clear 
the infusion line of drug and ensure all study drug has been administered to the patient. The 
patient should be monitored for one (1) hour following infusion. For more details please refer 
to the [Pharmacist Manual]. 
 
6.6.1 
Study treatment packaging and labeling 
Study treatment, crizanlizumab, will be provided as global clinical open supply and will be 
packed and labeled under the responsibility of Novartis, Drug Supply Management. 
Study treatment labels will comply with the legal requirements of each country and will include 
storage conditions, a unique medication number (corresponding to study treatment and strength) 
or randomization number if appropriate.

Study drug compliance and accountability 
 
6.6.3.1 
Study drug compliance 
Compliance will be assessed by administration of the study treatment under the supervision of 
the investigator or his/her designee and will be verified by determinations of crizanlizumab in 
serum. This information must be captured in the source document and in the Drug 
Accountability Form. 
 
6.6.3.2 
Study drug accountability 
The investigator or designee must maintain an accurate record of the shipment and dispensing 
of study treatment in a drug accountability log. Drug accountability will be noted by the field 
monitor during site visits and at the completion of the study. 
At study close-out, and, as appropriate during the course of the study, the investigator will return 
all used and unused study treatment, packaging, drug labels, and a copy of the completed drug

Visit schedule and assessments 
7.1 
Study flow and visit schedule 
Table 7-1 lists all of the assessments and indicates with an “X”, the visits when they are 
performed. All data obtained from these assessments must be supported in the patient’s source 
documentation. 
No CRF will be used as a source document. 
The table indicates which assessments produce data to be entered into the clinical database (D) 
or remain in source documents only (S) (“Category” column). 
Allowed visit windows are specified as follows: 
• Screening assessments, apart from those listed below, must occur within 35 days prior to 
the enrolment as per Table 7-1. 
• No visit window is allowed Week 1 Day 1 to Week 2 Day 1. And from Week 15 Day 1 to 
Week 16 Day 1 (or following the first week of steady state as specified in Table 7-5). 
• A ±1 days visit window is permitted on assessments Week 3 Day 1, Week 17 Day 1 and 
Week 18 Day 1 
• For all other visits a general ±3 days visit window is permitted on assessments to take into

7.1.2 
Screening 
After signing the study ICF, the screening assessments will be done within 1 to 35 days prior 
to Week 1 Day 1 (see Table 7-1 for list of assessments to be performed). The investigator will 
obtain consent / assent of patients and/or parents according to local procedures. 
Re-screening of patients is only allowed once per patient if the patient was not enrolled in the 
treatment phase before. In this case a new Subject Number will be assigned to the patient and 
the patient will be identified with this new number for the rest of his/her participation in the 
study. If patient has been enrolled and treated, re-screening of patient is not allowed. 
In case rescreening occurs, all evaluations re-assessed should meet the eligibility criteria. A new 
informed consent form must be signed only if there is an interruption in the patient’s eligibility 
evaluation and the investigator chooses to re-screen the patient following screen failure. If a 
new informed consent form is signed, AEs and medical history will be assessed relative to the 
new informed consent date. 
For laboratory evaluations used to determine eligibility, a repeated evaluation within the 
screening window is permitted for screening results out of the defined range before screen 
failing the patient. If the repeated laboratory result meets the criteria, that result may be used to 
determine eligibility. If the repeated laboratory result does not meet the criteria, the patient will 
be considered a screening failure. For details of assessments, see Table 7-1. 
 
 
 
7.1.2.1 
Eligibility screening 
The investigator is responsible to ensure only subjects who meet all inclusion and do not meet 
any exclusion criteria are included in the study. 
Patient eligibility will be checked by the Sponsor once all screening procedures are completed. 
The eligibility check form will be sent from the site to the Sponsor via email for evaluation. 
Upon confirmation of eligibility, the Sponsor will assign the patient either to the 5.0 mg/kg or 
7.5 mg/kg treatment group (according to the enrolment chronological order) and will return the 
signed eligibility check form via email to the site. The investigator site will then be allowed to 
assign treatment to the patient. Please refer and comply with detailed guidelines in the 
Eligibility check user guidelines. 
 
7.1.2.2 
Information to be collected on screening failures 
Patients who sign an informed consent but fail to be enrolled (patient who does not enter in the 
treatment phase) for any reason will be considered a screen failure. The reason for not being 
started on treatment will be entered on the Screening Phase Disposition Page. The demographic 
information, informed consent, Inclusion/Exclusion pages and, if applicable, withdrawal of 
informed consent must also be completed for Screen Failure patients. No other data will be 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 58
7 Protocol No. 
 
 
entered into the clinical database for patients who are screen failures, unless the patient 
experienced an SAE during the Screening Phase (see Section 8 for SAE reporting details). 
If a screen failure patient experiences an AE which does not meet the SAE criteria, details about 
the AE will be recorded only in the investigator’s source documents. In case of an SAE after 
signing of main study informed consent, data must be recorded on both the AE and SAE forms. 
If the patient fails to be enrolled, the Sponsor must be notified within 2 days of the screen fail 
via email that the patient was not enrolled. 
 
7.1.2.3 
Patient demographics and other baseline characteristics 
Subject demographic characteristics, which include age, gender, self-identified race and 
ethnicity, will be collected. 
Background medical information, including Sickle Cell and Vaso –Occlusive Crisis History, 
ECG, relevant and current medical history and alcohol and smoking history will also be 
collected. 
Other baseline characteristics and assessments performed at screening for eligibility are detailed 
in Table 7-1. 
 
7.1.3 
Run-in period 
Not Applicable 
 
7.1.4 
Treatment period 
The first 45 patients will receive crizanlizumab at 5mg/kg on week 1 day 1, week 3 day 1 and 
then every 4 weeks (week 7 day 1, week 11 day 1, etc.). Once 27 patients have evaluable PK 
and PD data (or a total of up to 45 patients are enrolled) at the 5.0 mg/kg dose, 10 additional 
patients will receive crizanlizumab at 7.5 mg/kg on week 1 day 1, week 3 day 1 and then every 
4 weeks. 
All patients will continue to receive study treatment and be followed as per the schedule of 
assessments, as long as patients derive benefit from crizanlizumab until any combination of the 
following will apply to all patients: 
• All patients have died or discontinued from the study 
• Crizanlizumab is commercially available for this patient population, and patients are 
eligible to be prescribed the commercial drug 
• Another clinical study becomes available that can continue to provide crizanlizumab in 
this patient population and all patients ongoing are eligible to be transferred to that clinical 
study. 
Full PK and PD profiles will be collected on week 1 days 1, 2 and 4, on day 1 of weeks 2, 3, 7 
and 11. From week 15 day 1, additional full PK and PD profiles will be collected on days 
1, 2, and 4 of week 15 (or at the time of the fifth infusion), on day 1 of weeks 16, 17, 18 and 
19. 
However, if the dose was interrupted and/or an infusion was delayed before week 15, then 
after 3 consecutive infusions have been given without an interruption of >7 days, the 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 59
7 Protocol No. 
 
 
additional full PK and PD profiles will be collected on days 1, 2, 4 of the week of the third 
consecutive infusion, and day 1 of the 4 consecutive weeks following the third infusion). 
Pre-dose PK and PD sampling will be collected prior to each infusion until week 51.
 
 
 
For details of assessments, see Table 7-1 and Table 7-5. 
 
7.1.5 
Discontinuation of study treatment 
Patients may voluntarily discontinue from the study treatment for any reason at any time. If a 
patient decides to discontinue from the study treatment, the investigator should make a 
reas onab l e effort (e.g. telephone, e-mail, letter) to  understand  the  primary reason  for 
this decision and record this information in the patient’s chart and on the appropriate CRF 
pages. They may be considered withdrawn if they state an intention to withdraw, fail to return 
for visits, or become lost to follow-up for any other reason. 
The investigator may discontinue study treatment for a given patient if he/she believes that 
continuation would be detrimental to the patient’s well-being. 
In addition to the mandatory reasons for discontinuation of study treatment listed in Section 6.3, 
study treatment must also be discontinued under the following circumstances: 
• Pregnancy 
• Lactation 
• Death 
• Subject/Guardian decision 
• Adjustments to study treatment due to toxicity that result in treatment discontinuation (see 
Section 6.3) 
• Use of prohibited medication (see Section 6.4). 
• Any other protocol deviation that results in a significant risk to the patient’s safety. 
Patients who discontinue study treatment should NOT be considered withdrawn from the 
study. They should return for the assessments indicated in Section 7.2.1 for an EOT visit and a 
safety Follow-Up visit. If they fail to return for these assessments for unknown reasons, every 
effort (e.g. telephone, email, letter) should be made to contact them as specified in Section 
7.1.6. 
Patients who discontinue study treatment should undergo an End of Treatment (EOT) visit 
followed by a 105 day safety follow-up. At EOT visit, all the assessments as listed in Table 7- 
1 will be performed. If the decision to discontinue the patient occurs at a regularly scheduled 
visit, that visit may serve as the EOT visit rather than having the patient return for an additional 
visit.

7.1.6 
Withdrawal of consent 
Subjects may voluntarily withdraw consent to participate in the study for any reason at any time. 
Withdrawal of consent occurs only when a subject: 
• Does not want to participate in the study anymore, and 
• Does not allow further collection of personal data 
In this situation, the investigator should make a reasonable effort (e.g. telephone, e-mail, letter) 
to understand the primary reason for the subject’s decision to withdraw his/her consent and 
record this information. 
Study treatment must be discontinued and no further assessments conducted, and the data that 
would have been collected at subsequent visits will be considered missing. 
Further attempts to contact the subject are not allowed unless safety findings require 
communicating or follow-up. 
All efforts should be made to complete the assessments prior to study withdrawal. A final 
evaluation at the time of the subject’s study withdrawal should be made as detailed in the 
assessment table. 
Novartis/sponsor will continue to keep and use collected study information (including any data 
resulting from the analysis of a subject’s samples until their time of withdrawal) according to 
applicable law. 
All biological samples not yet analyzed at the time of withdrawal may still be used for further 
testing/analysis in accordance with the terms of this protocol and of the informed consent form. 
 
7.1.7 
Follow up for safety evaluations 
All patients must have safety evaluations for 5 half-lives (105 days) after the last dose of study 
treatment. Once an AE is detected, investigators are required to follow this AE until its 
resolution or stabilization. Refer to Section 8.1.1 for definitions and reporting of AEs. Patients 
whose treatment is interrupted or discontinued due to an AE, including abnormal laboratory 
value, must be followed until resolution or stabilization of the event, whichever comes first. 
This could include all study assessments appropriate to monitor the event. 
Data collected should be added to the Adverse Events CRF and the Concomitant Medications 
CRF. 
Any SAEs experienced after the 105 day safety evaluation follow-up period should be reported 
to Novartis if the investigator suspects a causal relationship to the study treatment. 
If patients refuse to return for safety evaluation visits or are unable to do so, every effort should 
be made to contact them by telephone to determine their status. Attempts to contact the patient 
should be documented in the source documents (e.g., dates of telephone calls, registered letters, 
etc.). 
 
7.1.8 
Lost to follow-up 
For patients whose status is unclear because they fail to appear for study visits without stating 
an intention to withdraw consent, the investigator should show "due diligence" by contacting 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 61
7 Protocol No. 
 
 
the patient, family or family physician as agreed in the informed consent and by documenting 
in the source documents steps taken to contact the patient, e.g. dates of telephone calls, 
registered letters, etc. A patient should not be considered lost to follow-up until due diligence 
has been completed. Patients lost to follow up should be recorded as such on the appropriate 
CRF. 
 
7.2 
Assessment types 
7.2.1 
Efficacy assessments 
VOC is defined as pain crises (defined as an acute onset of pain for which in the opinion of the 
investigator there is no other medically determined explanation other than vaso-occlusion and 
which requires therapy with oral or parenteral opioids or parenteral NSAIDs) as well as other 
complicated crises, such as acute chest syndrome (ACS), priapism, and hepatic or splenic 
sequestration. 
For purposes of this study, the following detailed definitions will be used to identify each sub- 
type of VOC event: 
1. Uncomplicated pain crisis is defined as an acute episode of pain with no known cause for 
pain other than a vaso-occlusive event; and requiring treatment with a parenteral or oral 
opioids or parenteral NSAIDs; but is NOT classified as an acute chest syndrome, hepatic 
sequestration, splenic sequestration or priapism. The end of an uncomplicated pain crisis 
will be considered the resolution of acute pain, such that residual pain (or absence of any 
pain) is considered to be chronic, and the current pain medication regimen is considered to 
be for this chronic pain. 
2. Acute Chest Syndrome (ACS) is defined on the basis of the finding of a new pulmonary 
infiltrate involving at least one complete lung segment that was consistent with alveolar 
consolidation, but excluding atelectasis (as indicated by chest X-ray). At least one of the 
following additional signs or symptoms needs to be present as well: chest pain, a 
temperature of more than 38.5°C, tachypnea, wheezing or cough. ACS will be considered 
resolved when the patient is no longer hospitalized (unless for reason other than the ACS 
episode) and none of the additional signs or symptoms above are present. 
3. Priapism is defined as an unwanted or painful penile erection lasting at least 30 minutes. 
The end of an acute priapism event will be when the unwanted erection has resolved for at 
least 2 hours. 
4. Hepatic sequestration is defined on the basis of findings of right upper quadrant pain, an 
enlarged liver, and an acute decrease in hemoglobin concentration (e.g. a decrease in 
hemoglobin of ~ 2 g/dL). Acute hepatic sequestration will be considered resolved when 
right upper quadrant pain has returned to baseline (pre-event) levels and hemoglobin has 
been stable for 24 hrs. 
5. Splenic sequestration if defined on the basis of findings of left upper quadrant pain, an 
enlarged spleen, and an acute decrease in hemoglobin concentration (e.g., a decrease in 
hemoglobin of ~ 2 g/dL). Acute splenic sequestration will be considered resolved when 
left upper quadrant pain has returned to baseline (pre-event) levels and hemoglobin has 
been stable for 24 hrs.

Associated conditions in SCD (e.g., intermittent or chronic pain due to ankle/leg ulcers, aseptic 
necrosis of bone or gout) should not be considered VOC event. Similarly, complications such 
as pulmonary, cardiac, or renal failure are not themselves to be considered crises. If such events 
precipitate VOC, the VOC event will be documented separately. 
For each visit to a medical facility for a pain episode thought to be a VOC, the following 
information must be documented in the eCRF: diagnostic evaluation for the episode, patient 
treatment and management, course, duration of the crisis, and outcome. For patients who are 
treated at medical facilities other than the study site, summary documents (e.g. ER or hospital 
discharge summaries) will need to be obtained. Patients will be issued an investigational study 
participation card that requests this information and can be presented at each medical facility 
visit. 
Patients should be encouraged to contact the Investigator (or surrogate from the site) when they 
believe they are experiencing a VOC that they believe they can manage at home, both for 
treatment guidance and for accurate information may be obtained for the VOC eCRF page. 
VOCs treated at home but not documented by a telephone call within 24 hours of onset will not 
be counted as a VOC, due to concern over the accuracy of patient recall of all relevant details. 
If a patient experiences a VOC surrounding a protocol-scheduled visit day, and the patient 
presents for this visit, it will be counted as a VOC that led to a healthcare visit (provided the 
event meets the criteria for VOC discussed above). VOC is not a known contra-indication, but 
dosing during a crisis should be at investigator’s discretion. 
Any VOC symptoms occurring within 7 days following the documented resolution of a VOC 
will be counted as part of the prior crisis, and the date for end of VOC will be revised. 
Chest X-Ray must be conducted within the 3 months prior to week 1 day 1 . Chest X-Ray must 
be repeated in case of suspected ACS. 
Transfusion data should be collected from 30 days prior to Screening until the patient EOT visit. 
Patients participating in a chronic transfusion program (pre-planned series of transfusions for 
prophylactic purposes) are not eligible. Episodic transfusion in response to worsened anemia or 
VOC is permitted.

7.2.2 
Safety and tolerability assessments 
Safety will be monitored by assessing physical examinations, vital signs, ECG, laboratory 
assessments including hematology, chemistry, coagulation, urinalysis and as well as collecting 
of the adverse events at every visit. For details on AE collection and reporting, refer to Section 
8. 
 
7.2.2.1 
Physical examination 
The physical examination must be performed by the Investigator as scheduled in Table 7-1. 
A complete physical examination will include the examination of general appearance, skin, 
neck (including thyroid), eyes, ears, nose, throat, lungs, heart, abdomen, back, lymph nodes, 
extremities, vascular and neurological. If indicated based on medical history and/or symptoms, 
rectal, external genitalia, breast, and pelvic exams will be performed. A complete physical 
examination will be performed at Screening and within 7 days following last infusion. 
An abbreviated (short) physical exam will include the examination of general appearance and 
vital signs (blood pressure [BP] and pulse), as well as additional components of the physical 
exam, as needed based on observed signs or reported symptoms. A short physical exam will be 
performed at all visits for which there is a scheduled study drug infusion. 
Significant findings that were present prior to the signing of informed consent must be included 
in the Medical History page on the patient’s CRF. Significant new findings that begin or worsen 
after informed consent must be recorded on the Adverse Event page of the patient’s CRF. 
 
7.2.2.2 
Vital signs 
Vital signs include blood pressure (supine position preferred when ECG is collected), pulse 
measurement, respiratory rate and body temperature will be measured as specified in Table 7- 
1. 
 
7.2.2.3 
Height and weight 
Height will be measured at screening. 
Body weight (in indoor clothing, but without shoes) will be measured at screening and at all 
visits for which there is a scheduled study drug infusion (for dosing), as specified in Table 7-1. 
 
7.2.2.4 
Performance status 
ECOG performance status scale will be assessed at screening.

7.2.2.5 
Laboratory evaluations 
Clinical laboratory analyses (hematology, chemistry, urinalysis, coagulation, hepatitis and HIV 
markers and drug screen) are to be performed centrally unless otherwise noted in Table 7-3 
according to the schedule of assessments and collection plan outlined in Table 7-1. Details on 
the collection, shipment of samples and reporting of results by the central laboratory are 
provided to investigators in the Central Laboratory Manual/Flowchart. Visit windows are 
allowed for all visits (except from Week 1 Day to Week 2 Day 1 and Week 15 Day 1 to Week 
16 Day 1 (or following the first week of steady state) see Section 7.1). 
Novartis must be provided with a copy of the central laboratory’s certification (if applicable), 
and a tabulation of the normal ranges and units of each parameter collected in the eCRF. Any 
changes regarding normal ranges and units for laboratory values assessed during the study must 
be reported via an updated tabulation indicating the new effective date. Additionally, if at any 
time a patient has laboratory parameters obtained from a different (outside) laboratory, Novartis 
must be provided with a copy of the certification and a tabulation of the normal ranges and units 
for this laboratory as well. The investigator is responsible for reviewing all laboratory reports 
for patients in the study and evaluating any abnormalities for clinical significance. 
For assessment of patients’ eligibility for the study, only laboratory results from the 
central laboratory will be used (except in case of re-sampling at Day -14 and the results from 
the central laboratory are not yet available or are partial at time of the first infusion, then 
eligibility may be based on the results from the local laboratory. In such case, the results of the 
local laboratory will need to be recorded in the eCRF unscheduled pages and copy of the local 
lab normal ranges must be provided). 
Unscheduled local laboratory assessments may be performed if medically indicated to 
document a (potential) AE, if central laboratory results are unevaluable or inconclusive, or when 
the treating physician cannot wait for central laboratory results for decision making. In this 
particular situation, if possible, the blood sample obtained at the same time point should be 
submitted to the central laboratory for analysis in parallel with local analysis. 
The results of the local laboratory will be recorded in the eCRF if any the following criteria are 
met: 
• A treatment decision was made based on the local results, or 
• There are no concomitant central results available, or 
• Local lab results document an AE not reported by the central lab, or 
• Local lab results document an AE where the severity is worse than the one reported by the 
central lab, or 
• Eligibility had to be based on the local lab results due to pending / missing central lab 
results. 
At any time during the study up to safety follow-up, abnormal laboratory parameters which are 
clinically relevant and require an action to be taken with study treatment (e.g., require dose 
modification and/or interruption of study treatment, lead to clinical symptoms or signs, or 
require therapeutic intervention), whether specifically requested in the protocol or not, will be 
recorded on the AE eCRF page. The severity of laboratory data will be graded using the

b within 24hr before dose administration 
Note: In order to ensure ECG evaluation is received from the central laboratory for eligibility 
assessment, it is advisable to perform the ECG at least 72 hours prior to the scheduled 
enrollment date. 
In the event that a QTcF value of > 470 ms is observed or if an unscheduled ECG is performed 
for safety reasons, it is recommended to collect a time-matched PK sample and record the time 
and date of the last study drug intake to determine the drug exposure (refer to Section 7.2.3). In 
case of QT prolongation, study drug should be discontinued until normalized as described in 
Section 6.3.1.2 
Additional, unscheduled, safety ECGs may be repeated at the discretion of the investigator at 
any time during the study as clinically indicated. Unscheduled ECGs with clinically significant 
findings should be collected in triplicate. Local cardiologist ECG assessment may also be 
performed at any time during the study at the discretion of the investigator. 
All ECGs collected during the study, including unscheduled safety triplicate ECGs with 
clinically relevant findings, should be transmitted to the central core ECG laboratory for review. 
The results of the centrally assessed ECGs are automatically transferred into the clinical

database. Any original ECG not transmitted to a central laboratory should be forwarded for 
central review and a copy kept in the source documents at the study site. Interpretation of the 
tracing must be made by a qualified physician and documented on the ECG CRF page. Each 
ECG tracing should be labeled with the study number, patient initials (where regulations permit), 
subject number, date, and kept in the source documents at the study site. 
Clinically significant ECG abnormalities present at screening should be reported on the Medical 
History CRF page. New or worsened clinically significant findings occurring after informed 
consent must be recorded on the Adverse Events CRF page.

7.2.3 
Pharmacokinetics, pharmacodynamics, and immunogenicity 
Serial blood samples will be collected from all patients to assess PK and PD of crizanlizumab. 
Non-compartmental PK and PD parameters will be derived from each individual serum 
concentration- or inhibition-time profile using appropriate methods and software. Refer to 
Section 10.5.4 for a table of PK parameters that will be derived. 
 
 
 
7.2.3.1 
Pharmacokinetic, pharmacodynamic, and immunogenicity blood 
collection and handling 
At specified time points described in Table 7-5, blood samples should be collected from the 
arm opposite from the investigational drug infusion into serum separator tubes. All blood 
samples will be taken by either direct venipuncture or an indwelling cannula inserted in a 
forearm vein. 4.5 mL blood draws should be collected when PK and PD are specified. 8 mL 
blood draws should be collected when PK, PD and inmunogenicity (IG) samples are needed. 
The blood samples will be allowed to clot for approximately 30 minutes at room temperature 
and then centrifuged for 10 minutes at approximately 3000g. Each serum sample will be 
aliquoted, and transferred into freezer-proof polypropylene screw-cap tubes (2 tubes for PK, 2 
tubes for PD and 3 tubes for IG at each specified time points, at least 0.5 mL serum in each 
tube). The serum tubes will be frozen within 90 minutes of venipuncture and kept below -70°C 
in an upright position pending shipment and analysis. 
Each serum samples should be labeled with the appropriate study, center and subject numbers, 
as well as the sequential PK/PD/IG sample and PK/PD/IG collection number with a unique 
sample number. The actual collection date and time of each sample will be entered on the 
PK/PD/IG Blood Collection eCRF pages. 
Refer to the [CSEG101A2202 Laboratory Manual] for detailed instructions for the collection, 
handling, and shipment of samples.

Analytical method 
The crizanlizumab PK assay is a target capture ELISA to determine the concentration of 
crizanlizumab remaining in serum samples. Concentrations below the lower limit of 
quantification will be reported as 0.00 ng/mL and missing samples will be labeled accordingly. 
A pharmacodynamic marker of crizanlizumab is the ex vivo P-selectin inhibition measured by 
a surface plasmon resonance assay using human serum samples. Crizanlizumab in serum 
samples binds to spiked Psel-Ig (P-selectin coupled to Ig) and inhibits its binding to a PSGL1 
peptide. 
Immunogenicity determination will be performed using a bridging immunoassay format 
validated for Immunogenicity screening in human serum samples. 
Details of each analytical method will be given in bioanalytical data reports.

Safety monitoring and reporting 
8.1 
Adverse events 
8.1.1 
Definitions and reporting 
An adverse event is defined as the appearance of (or worsening of any pre-existing) undesirable 
sign(s), symptom(s), or medical condition(s) that occur after patient’s signed informed consent 
has been obtained. 
Abnormal laboratory values or test results occurring after informed consent constitute adverse 
events only if they induce clinical signs or symptoms, are considered clinically significant, 
require therapy (e.g., hematologic abnormality that requires transfusion or hematological stem 
cell support), or require changes in study medication(s). 
Adverse events that begin or worsen after informed consent should be recorded in the Adverse 
Events CRF. Conditions that were already present at the time of informed consent should be 
recorded in the Medical History page of the patient’s CRF. Adverse event monitoring should 
be continued for at least 105 days (5 half-lives of crizanlizumab) following the last dose of 
study treatment. Adverse events (including lab abnormalities that constitute AEs) should be 
described using a diagnosis whenever possible, rather than individual underlying signs and 
symptoms. When a clear diagnosis cannot be identified, each sign or symptom should be 
reported as a separate Adverse Event. 
Adverse events will be assessed and graded according to the Common Terminology Criteria for 
Adverse Events (CTCAE) version 
If CTCAE grading does not exist for an adverse event, the severity of mild, moderate, severe, 
and life-threatening, death related to the AE corresponding respectively to Grades 1 - 5, will be 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 74
7 Protocol No. 
 
 
used. Information about any deaths (related to an Adverse Event or not) will also be collected 
though a Death form. 
The occurrence of adverse events should be sought by non-directive questioning of the patient 
during the screening process after signing informed consent and at each visit during the study. 
Adverse events also may be detected when they are volunteered by the patient during the 
screening process or between visits, or through physical examination, laboratory test, or other 
assessments. As far as possible, each adverse event should be evaluated to determine: 
• The severity grade (CTCAE Grade 1-5) 
• Its duration (Start and end dates) 
• Its relationship to the study treatment (Reasonable possibility that AE is related: No, Yes) 
• Action taken with respect to study or investigational treatment (none, dose adjusted for the 
7.5 mg/kg dosage only, temporarily interrupted, permanently discontinued, unknown, not 
applicable) 
• Whether medication or therapy was given (no concomitant medication/non-drug therapy, 
concomitant medication/non-drug therapy) 
• Whether it is serious, where a serious adverse event (SAE) is defined as in Section 8.2.1 
and which seriousness criteria have been met 
• Outcome (not recovered/not resolved, recovered/resolved, recovered/resolved with 
sequelae, fatal, unknown). 
If the event worsens the event should be reported a second time in the CRF noting the start date 
when the event worsens in toxicity. For grade 3 and 4 adverse events only, if improvement to a 
lower grade is determined a new entry for this event should be reported in the CRF noting the 
start date when the event improved from having been Grade 3 or Grade 4. 
All adverse events should be treated appropriately. If a concomitant medication or non-drug 
therapy is given, this action should be recorded on the Adverse Event CRF. 
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 treatment, the interventions 
required to treat it, and the outcome. 
 
8.1.1.1 
Protocol Exempt AEs & SAEs 
Protocol Exempt AEs & SAEs are implemented in the SEG101 program. VOCs must be 
reported on the VOC page in the eCRF. As VOCs are considered secondary endpoints for the 
purpose of evaluation of efficacy, AEs and SAEs involving VOCs SHOULD NOT be reported 
as AEs or SAEs for the purpose of this study. These events will not be considered as SAEs in 
regards to reporting requirements.Vaso-occlusive crisis (including fatal outcomes), if 
documented by use of appropriate method and in accordance with the definition described in 
Section 7.2.1 of this protocol will not be reported as a serious adverse event to Novartis 
according to the requirements in Section 8.2 of this protocol. In case that new information arises 
which changes the diagnosis of a VOC, i.e. gives another medically determined explanation 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 75
7 Protocol No. 
 
 
than vaso-occlusion in the opinion of the investigator, the event has to be reported according to 
the rules of Section 8.1 and Section 8.2 and must be reported to Novartis within 24 hours of 
learning of the new information. 
The events in Table 8-1 are the VOCs that will not be reported as AEs/SAEs. 
 
Table 8-1 
List of VOC Events Not Requiring AE/SAE Reporting 
 
VOC Event 
Uncomplicated sickle cell-related pain crisis (SCPC) or vaso-occlusive crisis (VOC)* 
Acute chest syndrome 
Hepatic sequestration 
Splenic sequestration 
Priapism requiring a visit to a medical facility 
*VOC is defined as pain crises (defined as an acute onset of pain for which there is no other 
medically determined explanation other than vaso-occlusion and which requires therapy with 
oral or parenteral opioids or parenteral NSAIDs) as well as other complicated crises, such as 
acute chest syndrome (ACS), priapism, and hepatic or splenic sequestration. 
 
8.1.2 
Laboratory test abnormalities 
 
8.1.2.1 
Definitions and reporting 
Laboratory abnormalities that constitute an Adverse event in their own right (are considered 
clinically significant, induce clinical signs or symptoms, require concomitant therapy or require 
changes in study treatment), should be recorded on the Adverse Events CRF. Whenever 
possible, a diagnosis, rather than a symptom should be provided (e.g. anemia instead of low 
hemoglobin). Laboratory abnormalities that meet the criteria for Adverse Events should be 
followed until they have returned to normal or an adequate explanation of the abnormality is 
found. When an abnormal laboratory or test result corresponds to a sign/symptom of an already 
reported adverse event, it is not necessary to separately record the lab/test result as an additional 
event. 
Laboratory abnormalities, that do not meet the definition of an adverse event, should not be 
reported as adverse events. A Grade 3 or 4 event (severe) as per CTCAE does not automatically 
indicate a SAE unless it meets the definition of serious as defined below and/or as per 
investigator’s discretion. A dose hold or medication for the lab abnormality may be required by 
the protocol in which case the lab abnormality would still, by definition, be an adverse event 
and must be reported as such. 
 
8.1.3 
Adverse events of special interest 
Adverse events of special interest (AESI) are defined as events (serious or non-serious) which 
are ones of scientific and medical concern specific to the sponsor’s product or program, for 
which ongoing monitoring and rapid communication by the investigator to the sponsor may be 
appropriate. Such events may require further investigation in order to characterize and 
understand them. 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 76
7 Protocol No. 
 
 
Adverse events of special interest are defined on the basis of an ongoing review of the safety 
data. 
 
8.2 
Serious adverse events 
8.2.1 
Definitions 
Serious adverse event (SAE) is defined as one of the following: 
• Is fatal or life-threatening 
• Note: fatal or life-threatening VOCs are not considered an SAE and should be recorded on 
the appropriate VOC eCRF page 
• Results in persistent or significant disability/incapacity 
• Constitutes a congenital anomaly/birth defect 
• Is medically significant, i.e., defined as an event that jeopardizes the patient or may 
require medical or surgical intervention to prevent one of the outcomes listed above 
• Requires inpatient hospitalization or prolongation of existing hospitalization, 
• Note that hospitalizations for the following reasons should not be reported as serious 
adverse events: 
• Vaso-occlusive crisis as defined in the protocol 
• 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 that is unrelated to the 
indication under study and has not worsened since signing the informed consent 
• Social reasons and respite care in the absence of any deterioration in the patient’s 
general condition 
• Note that treatment on an emergency outpatient basis that does not result in hospital 
admission and involves an event not fulfilling any of the definitions of a SAE given above 
is not a serious adverse event 
 
8.2.2 
Reporting 
To ensure patient safety, every SAE, regardless of suspected causality, occurring after the 
patient has provided informed consent and until at least 105 days after the patient has stopped 
study treatment must be reported to Novartis within 24 hours of learning of its occurrence. 
Any additional information for the SAE including complications, progression of the initial SAE, 
and recurrent episodes must be reported as follow-up to the original episode within 24 hours of 
the investigator receiving the follow-up information. An SAE occurring at a different time 
interval or otherwise considered completely unrelated to a previously reported one should be 
reported separately as a new event. 
Any SAEs experienced after the 105 day safety evaluation follow-up period should only be 
reported to Novartis if the investigator suspects a causal relationship to the study treatment. 
Information about all SAEs is collected and recorded on the Serious Adverse Event Report 
Form; all applicable sections of the form must be completed in order to provide a clinically 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 77
7 Protocol No. 
 
 
thorough report. The investigator must assess and record the relationship of each SAE to each 
specific study treatment (if there is more than one study treatment), complete the SAE Report 
Form in English, and submit the completed form within 24 hours to Novartis. Detailed 
instructions regarding the SAE submission process and requirements for signatures are to be 
found in the investigator folder provided to each site. 
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. The follow-up information should describe 
whether the event has resolved or continues, if and how it was treated, whether the blind was 
broken or not, and whether the patient continued or withdrew from study participation. 
If the SAE is not previously documented in the Investigator’s Brochure and is thought to be 
related to the Novartis study treatment, an oncology Novartis Chief Medical Office and Patient 
Safety (CMO&PS) 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 drug 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 Directive 2001/20/EC or as per national regulatory requirements in 
participating countries. 
 
8.3 
Emergency unblinding of treatment assignment 
Not applicable. 
 
8.4 
Pregnancies 
To ensure patient safety, each pregnancy occurring while the patient is on study treatment must 
be reported to Novartis within 24 hours 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. 
Pregnancy should be recorded on a Clinical Trial Pregnancy Form and reported by the 
investigator to the oncology Novartis Chief Medical Office and Patient Safety (CMO&PS). 
Pregnancy follow-up should be recorded on the same form and should include an assessment 
of the possible relationship to the study treatment any pregnancy outcome. Any SAE 
experienced during pregnancy must be reported on the SAE Report Form. 
Pregnancy outcomes should be collected for the female partners of any males who took study 
treatment in this study. Consent to report information regarding these pregnancy outcomes 
should be obtained from the mother. 
 
8.5 
Warnings and precautions 
No evidence available at the time of the approval of this study protocol indicated that special 
warnings or precautions were appropriate, other than those noted in the provided Investigator 
Brochure. Additional safety information collected between IB updates will be communicated 
in the form of Investigator Notifications. This information will be included in the patient 
informed consent and should be discussed with the patient during the study as needed.

Data collection and management 
9.1 
Data confidentiality 
Information about study subjects will be kept confidential and managed under the applicable 
laws and regulations. Those regulations require a signed subject authorization informing the 
subject of the following: 
• What protected health information (PHI) will be collected from subjects in this study 
• Who will have access to that information and why 
• Who will use or disclose that information 
• The rights of a research subject to revoke their authorization for use of their PHI. 
In the event that a subject revokes authorization to collect or use PHI, the investigator, by 
regulation, retains the ability to use all information collected prior to the revocation of subject 
authorization. For subjects that have revoked authorization to collect or use PHI, attempts 
should be made to obtain permission to collect follow-up safety information (e.g. has the subject 
experienced any new or worsened AEs) at the end of their scheduled study period. 
The data collection system for this study uses built-in security features to encrypt all data for 
transmission in both directions, preventing unauthorized access to confidential participant 
information. Access to the system will be controlled by a sequence of individually assigned 
user identification codes and passwords, made available only to authorized personnel who have 
completed prerequisite training. 
Prior to entering key sensitive personally identifiable information (Subject Initials and exact 
Date of Birth), the system will prompt site to verify that this data is allowed to be collected. If 
the site indicates that country rules or ethics committee standards do not permit collection of 
these items, the system will not solicit Subject Initials. Year of birth will be solicited (in the 
place of exact date of birth) to establish that the subject satisfies protocol age requirements and 
to enable appropriate age-related normal ranges to be used in assessing laboratory test results. 
 
9.2 
Site monitoring 
Before study initiation, at a site initiation visit or at an investigator’s meeting, Novartis 
personnel (or designated CRO) will review the protocol and CRFs with the investigators and 
their staff. During the study, the field monitor will visit the site regularly to check the 
completeness of patient records, the accuracy of entries on the CRFs, the adherence to the 
protocol to Good Clinical Practice, the progress of enrollment, and to ensure that study 
treatment is being stored, dispensed, and accounted for according to specifications. Key study 
personnel must be available to assist the field monitor during these visits. 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 79
7 Protocol No. 
 
 
The investigator must maintain source documents for each patient 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 recorded on CRFs must be traceable to source documents in the 
patient's file. The investigator must also keep the original signed informed consent form (a 
signed copy is given to the patient). 
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 inclusion/exclusion criteria and documentation 
of SAEs. Additional checks of the consistency of the source data with the CRFs are performed 
according to the study-specific monitoring plan. 
 
9.3 
Data collection 
The designated investigator staff will enter the data required by the protocol into the Electronic 
Case Report Forms (eCRF). The eCRFs have been built using fully validated secure web- 
enabled software that conforms to 21 CFR Part 11 requirements, Investigator site staff will not 
be given access to the EDC system until they have been trained. Automatic validation programs 
check for data discrepancies in the eCRFs and, allow modification or verification of the entered 
data by the investigator staff. 
The investigator must certify that the data entered into the eCase Report Form is complete and 
accurate, and that entry and updates are performed in a timely manner. 
For PK, PD 
 samples, information about Treatment Periods, Visits, time points, 
and date and time of sample collection will be recorded on the eCRFs and also on the requisition 
forms sent to Central labs. A reconciliation of information regarding subjects and samples 
between the eCRF database and the lab database will be carried out by designated Novartis 
personnel (or designated CRO). 
 
9.4 
Database management and quality control 
Novartis personnel (or designated CRO) will review the data entered by investigational staff 
for completeness and accuracy. Electronic data queries stating the nature of the problem and 
requesting clarification will be created for discrepancies and missing values and sent to the 
investigational site via the EDC system. Designated investigator site staff are required to 
respond promptly to queries and to make any necessary changes to the data. 
Concomitant treatments and prior 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. 
Any samples or data to be analyzed centrally (PK, PD, 
 central laboratory, central 
ECG reading) will be processed centrally and the results will be sent electronically to Novartis 
(or a designated CRO). 
At the conclusion of the study, the occurrence of any protocol violations will be determined. 
After these actions have been completed and the data has been verified to be complete and 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 80
7 Protocol No. 
 
 
accurate, the database will be declared locked and made available for data analysis. 
Authorization is required prior to making any database changes to locked data, by joint written 
agreement between the Global Head of Biostatistics, the Global Head of Data Management and 
the Global Head of Clinical Development. 
After database lock, the investigator will receive copies of the patient data for archiving at the 
investigational site.

Statistical methods and data analysis 
The analysis of study data for the primary clinical study report (CSR) will be based on all patient 
data up to the time after the primary PK and PD parameters are available for at least 27 patients 
for 5.0 mg/kg treatment group in the PAS1 and PDS1 respectively, or a total of 45 patients have 
been enrolled in the 5.0 mg/kg treatment group, whichever occurs first. 
The additional data for any patients continuing to receive study drug past this time, as allowed 
by the protocol, will be further summarized in a final study report once these patients have 
completed or discontinued the study. 
 
10.1 
Analysis sets 
10.1.1 
Full Analysis Set 
The Full Analysis Set (FAS) comprises all patients to whom study treatment has been assigned 
and who received at least one dose of study treatment. Patients will be analyzed according to 
the crizanlizumab dose (5.0 mg/kg or 7.5 mg/kg) they have been assigned to. 
 
10.1.2 
Safety set 
The Safety Set includes all patients who received at least one dose of study treatment. Patients 
will be analyzed according to the dose level received (5.0 mg/kg or 7.5 mg/kg), where dose 
level received is defined as the assigned dose level if the patient took at least one dose of that 
treatment or the first dose received if the assigned dose level was never received. 
 
10.1.3 
Pharmacokinetic analysis set 
The Pharmacokinetic analysis set 1 (PAS1) includes all patients who provide at least one 
evaluable PK profile. A profile is considered evaluable if all of the following conditions are 
satisfied: 
• Patient receives the planned treatment of 5.0 mg/kg or 7.5 mg/kg before single dose PK 
profile or 3 consecutive doses of the planned treatment before the multiple dose PK profile 
• Patient provides at least one primary PK parameter 
• Patient does not have any transfusion of blood product in the last 4 weeks before the first 
PK sample of the full PK profile, or during the full PK profile 
The Pharmacokinetic analysis set 2 (PAS2) includes all patients who receive at least one 
planned treatment of 5.0 mg/kg or 7.5 mg/kg and provide at least one corresponding evaluable 
PK concentration.

Safety set who have at least one trough concentration or one p-selectin inhibition. 
 
10.2 
Patient demographics/other baseline characteristics 
Demographic and other baseline data will be listed and summarized descriptively by treatment 
group for all patients for the FAS. 
Categorical data will be presented as frequencies and percentages. For continuous data, mean, 
standard deviation, median, minimum, and maximum will be presented. 
Relevant medical histories will be summarized by system organ class and preferred term. 
 
10.3 
Treatments (study treatment, concomitant therapies, 
compliance) 
The Safety set will be used for the analyses below. Categorical data will be summarized as 
frequencies and percentages. For continuous data, mean, standard deviation, median, minimum, 
and maximum will be presented. 
The duration of exposure in days to study drug as well as the dose intensity (computed as the 
ratio of actual cumulative dose received and actual duration of exposure) and the relative dose 
intensity (computed as the ratio of dose intensity and planned dose intensity) will be 
summarized by means of descriptive statistics using the safety set. 
The number of patients with dose adjustments (interruption or permanent discontinuation) and 
the reasons will be summarized for all patients by treatment group and all dosing data will be 
listed.

Chemical (ATC) classification system for all patients. 
 
10.4 
Primary objective 
The primary objective is to characterize the PK and PD of crizanlizumab at 5.0 mg/kg in adult 
SCD patients. 
 
10.4.1 
Variables 
The primary variables of the study are the PK and PD parameters after single dose and after 
multiple doses. 
 
Primary PK parameters: 
• AUCd15, AUCtau, Cmax 
The remaining PK parameters will be analyzed as secondary variables. 
 
PD parameters of crizanlizumab 
• PD-AUCd15 after single dose 
• PD-AUCd29 after multiple doses 
10.4.2 
Statistical hypothesis, model, and method of analysis 
The inter-subject variations and CV% will be presented for the primary PK parameters. The 
point estimate and the corresponding two-sided 90% confidence interval (CI) for the mean of 
the log-transformed primary PK parameters after single dose and multiple doses will be derived 
respectively. The point estimate and CI will be anti-log transformed to obtain the point estimate 
and the 90% confidence interval for the geometric mean on the original scale. 
The descriptive statistics (n, mean, CV%, standard deviation (SD), median, geometric mean, 
geometric CV%, minimum and maximum) will be presented for all PK parameters defined in

Secondary objectives 
The secondary objectives in this study are to assess the efficacy, safety and tolerability of 
crizanlizumab at 5.0 mg/kg and 7.5 mg/kg in SCD patients. The FAS will be used for all 
analyses. 
 
10.5.1 
Key secondary objective(s) 
Not applicable. 
 
10.5.2 
Other secondary efficacy objectives 
The following endpoints will be summarized descriptively by treatment group. 
• Annualized rate of VOC events leading to healthcare visit in clinic/ER/hospital 
• Annualized rate of VOC events treated at home, based on documentation by health care 
provider following phone contact with patient 
• Annualized rate of all VOC events (including both healthcare visit and home treatment) 
• Annualized rate of each subcategory of VOC event (uncomplicated pain crisis, acute chest 
syndrome, hepatic sequestration, splenic sequestration, priapism) 
• Annualized rate of hospitalizations and ER visits (both overall and VOC-related) 
• Annualized days of hospitalizations and ER visits (both overall and VOC-related) 
10.5.3 
Safety objectives 
 
10.5.3.1 Analysis set and grouping for the analyses 
For all safety analyses, the safety set will be used. All safety data will be summarized by 
treatment group. 
The overall observation period will be divided into three mutually exclusive segments: 
1. pre-treatment period: from day of patient’s informed consent to the day before first dose 
of study medication 
2. on-treatment period: from day of first dose of study medication to 105 days after last dose 
of study medication 
3. post-treatment period: starting at day 106 after last dose of study medication. 
 
10.5.3.2 Adverse events (AEs) 
Summary tables for adverse events (AEs) will include only AEs that started or worsened during 
the on-treatment period, the treatment-emergent AEs. 
The incidence of treatment-emergent adverse events (new or worsening from baseline) will be 
summarized by system organ class and or preferred term, severity (based on CTCAE grades), 
type of adverse event, relation to study treatment by treatment group. 
Serious adverse events, non-serious adverse events and adverse events of special interest (AESI) 
during the on-treatment period will be tabulated. 
All deaths (on-treatment and post-treatment) will be summarized.

All AEs, deaths and serious adverse events (including those from the pre and post-treatment 
periods) will be listed and those collected during the pre-treatment and post-treatment period 
will be flagged. 
 
10.5.3.3 Laboratory abnormalities 
Grading of laboratory values will be assigned programmatically as per NCI Common 
Terminology Criteria for Adverse Events (CTCAE) version 4.03. The calculation of CTCAE 
grades will be based on the observed laboratory values only, clinical assessments will not be 
taken into account. 
CTCAE Grade 0 will be assigned for all non-missing values not graded as 1 or higher. 
For laboratory tests where grades are not defined by CTCAE v4.03, results will be categorized 
as low/normal/high based on laboratory normal ranges. 
The following summaries will be generated separately for hematology and biochemistry tests 
by treatment group: 
• Listing of all laboratory data with values flagged to show the corresponding CTCAE 
v4.03 grades if applicable and the classifications relative to the laboratory normal ranges 
For laboratory tests where grades are defined by CTCAE v4.03 
• Worst post-baseline CTCAE grade (regardless of the baseline status). Each patient will be 
counted only once for the worst grade observed post-baseline. 
• Shift tables using CTCAE v4.03 grades to compare baseline to the worst on-treatment 
value 
For laboratory tests where grades are not defined by CTCAE v4.03, 
• Shift tables using the low/normal/high/ (low and high) classification to compare baseline 
to the worst on-treatment value. 
In addition to the above mentioned tables and listings, other 
 analyses, for example 
figures plotting time course of raw or change in laboratory tests over time or box plots might 
be specified in the analysis plan. 
10.5.3.4 Other safety data 
ECG 
12 lead ECGs including PR, QRS, QT, QTcF and HR intervals will be obtained centrally for 
each patient during the study. ECG data will be read and interpreted centrally. 
The number and percentage of patients with notable ECG values will be presented. In addition, 
a listing of these patients will be produced. 
 
Vital signs 
Data on vital signs will be tabulated and listed, notable values will be flagged.

Interim analysis 
An interim analysis may be performed when there are at least 27 patients with single dose 
evaluable PK profiles and approximately 5 patients with both single dose and multiple dose 
evaluable PK profiles in the PAS1 for 5.0 mg/kg treatment group. Point estimate and 90% 
confidence intervals for the primary PK parameters will be calculated. PopPK modeling will be 
performed. Another interim analysis may be performed when there are approximately 15 
patients with multiple dose evaluable PK profiles in the 5.0 mg/kg treatment group in the PAS1. 
Should the criteria for the two interim analyses be reached at similar times compatible with both 
objectives, a single combined interim analysis will be performed. Additional earlier or later ad 
hoc interim analyses of PK/PD/safety may be performed in order to support potential health 
authority requests. 
 
10.8 
Sample size calculation 
5.0 mg/kg treatment group: 
For sample size consideration, PK and PD data from Study CSEG101A2101 and study 
CSEG101A2201 were used. Currently, the inter-subject variability of PK parameters, such as 
AUC and Cmax, of VOC patients is not known and needs to be approximated from the Ctrough 
results of patient study A2201. In that study the inter-subject variability of Ctrough was found 
to be 50.8%. 
Data of study A2101 has revealed a high correlation between PK concentrations 336h post-dose 
and AUCt. Assuming this correlation holds true for patients together with the assumption of an 

Novartis 
Amended Protocol Version 01 Clean 
Confidential 
Page 90
7 Protocol No. 
 
 
inter-subject CV = 50.8% of pre-dose concentrations allows an approximation of expected inter- 
subject CV = 46.1% for AUCt. 
Currently, the inter-subject variation of the P-Selectin inhibition at 5.0 mg/kg and the respective 
PDAUC672hr is not known. However, approximations utilizing results from lower dose groups 
tested in study CSEG101A2101 suggest an inter-subject coefficient of variation of 
approximately CV = 34.1%. 
When the sample size is 27 evaluable patients, a two-sided 90% confidence interval for a single 
mean of log-transformed AUC will extend 0.140 from the observed mean, ensuring a precision 
of 15%, assuming that the standard deviation is known to be 0.439 and the confidence interval 
is based on the large sample z statistic. 
Similarly, with the same sample size of 27 evaluable patients, a two-sided 90% confidence 
interval for a single mean of log-transformed PD-AUC will extend 0.105 from the observed 
mean, representing a precision of about 11%, assuming that the standard deviation is known to 
be 0.332 and the confidence interval is based on the large sample z statistic. 
After the start of trial A2202, new information was made available through the single dose HV 
study CSEG101A2102, in which PK variability for SEG101 was lower than for SelG1. Using 
the same process as described above, but this time starting from the CV% in A2102 SEG101 
rather than A2101 SelG1, leads to the CV% for AUCt in patients being projected to be 34.7%, 
instead of 46.1%. 
With such assumption for a lower CV%, a smaller sample size of 15 patients would be sufficient 
to ensure the same precision as originally expected with 27 evaluable patients: with 15 evaluable 
patients, a two-sided 90% confidence interval for a single mean of log-transformed AUC will 
extend 0.143 from the observed mean, still ensuring a precision of 15%, assuming that the 
standard deviation is known to be 0.3369 and the confidence interval is based on the large 
sample z statistic. 
However, considering the uncertainties around variability estimations (projected based on a 
single-dose HV study rather than directly observed in a multiple-dose patient study), the sample 
size of 27 for the primary analysis is maintained and an interim analysis will be conducted on 
15 evaluable patients. 
Exploratory 7.5 mg/kg treatment group: 
When the sample size for this dose group is 6, a two-sided 90% confidence interval for a single 
mean will extend 0.172 from the observed mean, assuming that the standard deviation is known 
to be 0.209 and the confidence interval is based on t-statistic. 
Considering a drop-out rate of 35% from the CSEG101A2201 study, and to account for the 
heterogeneity of patients in terms of genotype and renal function, the multiplication factor for 
enrollment versus evaluable patients is 67%, and 45 patients will need to be enrolled in the 5.0 
mg/kg treatment group. The same holds for the exploratory cohort, requiring enrollment of 10 
patients to yield 6 evaluable patients at the 7.5 mg/kg dose.

11.6 
Study documentation, record keeping and retention of 
documents 
Each participating site will maintain appropriate medical and research records for this trial, in 
compliance with Section 4.9 of the ICH E6 GCP, and regulatory and institutional requirements 
for the protection of confidentiality of subjects. As part of participating in a Novartis-sponsored 
study, each site will permit authorized representatives of the sponsor(s) and regulatory agencies 
to examine (and when required by applicable law, to copy) clinical records for the purposes of 
quality assurance reviews, audits and evaluation of the study safety and progress. 
Source data are all information, original records of clinical findings, observations, or other 
activities in a clinical trial necessary for the reconstruction and evaluation of the trial. Examples 
of these original documents and data records include, but are not limited to, hospital records, 
clinical and office charts, laboratory notes, memoranda, subjects’ diaries or evaluation 
checklists, pharmacy dispensing records, recorded data from automated instruments, copies or 
transcriptions certified after verification as being accurate and complete, microfiches, 
photographic negatives, microfilm or magnetic media, x-rays, and subject files and records kept

at the pharmacy, at the laboratories, and medico-technical departments involved in the clinical 
trial. 
Data collection is the responsibility of the clinical trial staff at the site under the supervision of 
the site Principal Investigator. The study case report form (CRF) is the primary data collection 
instrument for the study. The investigator should ensure the accuracy, completeness, legibility, 
and timeliness of the data reported in the CRFs and all other required reports. Data reported on 
the CRF, that are derived from source documents, should be consistent with the source 
documents or the discrepancies should be explained. All data requested on the CRF must be 
recorded. Any missing data must be explained. Any change or correction to a paper CRF should 
be dated, initialed, and explained (if necessary) and should not obscure the original entry. For 
electronic CRFs an audit trail will be maintained by the system. The investigator should retain 
records of the changes and corrections to paper CRFs. 
The investigator/institution should maintain the trial documents as specified in Essential 
Documents for the Conduct of a Clinical Trial (ICH E6 Section 8) and as required by applicable 
regulations and/or guidelines. The investigator/institution should take measures to prevent 
accidental or premature destruction of these documents. 
Essential documents (written and electronic) should be retained for a period of not less than 
fifteen (15) years from the completion of the Clinical Trial unless Sponsor provides written 
permission to dispose of them or, requires their retention for an additional period of time 
because of applicable laws, regulations and/or guidelines. 
 
11.7 
Confidentiality of study documents and patient records 
The investigator must ensure anonymity of the patients; patients must not be identified by names 
in any documents submitted to Novartis. Signed informed consent forms and patient enrollment 
log must be kept strictly confidential to enable patient identification at the site. 
 
11.8

Source data/documents must be available to inspections by Novartis or designee or Health 
Authorities. 
 
11.9 
Financial disclosures 
Financial disclosures should be provided by study personnel who are directly involved in the 
treatment or evaluation of patients at the site - prior to study start. 
 
12 
Protocol adherence 
Investigators ascertain they will apply due diligence to avoid protocol deviations. Under no 
circumstances should the investigator contact Novartis or its agents, if any, monitoring the study 
to request approval of a protocol deviation, as no authorized deviations are permitted. 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.
