S1P

1R

signaling on CCR7+

lymphocytes (central

memory T cells) facilitate

their exit from lymph nodes 

along an S1P gradient

•

Ozanimod induces S1P

1R

internalization so

lymphocytes do not respond

to S1P and are retained in

the lymph node

•

Protective immunity is

generally preserved since

CCR7-

lymphocytes (effector

memory T cells) do not

circulate through the lymph

nodes

•

Fingolimod

is

the

first

S1P

receptor

modulator

(S1P

1,3,4,5R

)

and

oral

agent approved in 2010 for the treatment of Relapsing Multiple

Sclerosis (RMS)

•

Well established efficacy and safety profile

•

Over 100,000 patients have been treated with Fingolimod

•

No increase in serious infections, opportunistic infections, TB,

PML or malignancies over time

•

Warnings and Precautions include first dose cardiac effects (HR

reduction and cardiac conduction abnormalities), LFT elevations,

and macular edema

•

Ozanimod

(RPC1063)

is

a

next

generation

oral

S1P

receptor

modulator

•

Increased

selectivity

for

the

S1P

1R

and

S1P

5R

•

Improved pharmaceutic properties that allow for enhanced tissue

penetration and faster clearance

•

Demonstrated efficacy in a Phase 2 trial in RMS patients

•

Clinical trial experience to date has demonstrated an improved

cardiovascular

profile,

reduced

LFT

elevations,

no

macular

edema

and rapid lymphocyte recovery

Study Endpoints and Methods

•

Primary Efficacy Endpoint

•

Proportion of patients in clinical remission at Week 8,

defined as a Mayo score

2 points with no subscore > 1

point

•

Key Secondary Efficacy Endpoints

•

Proportion of patients with clinical response at Week 8

•

Change from Baseline in Mayo score at Week 8

•

Proportion of patients with mucosal improvement/mucosal

healing (endoscopic subscore

•

Methods

•

All endoscopies were read centrally by a blinded evaluator

for both eligibility confirmation and endpoint scoring

•

Subjects with different central and local endoscopic sub-

scores had an additional central read and adjudication
