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

Modulators
•
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 |
