Long-term

Safety
Trial
(LASSO)
open-label
interventional
studies
of
allopurinol
in gout patients otherwise eligible for the following Phase 3 studies:
Combination Study of Lesinurad in Allopurinol Standard of Care Inadequate Responders
(CLEAR #1)
randomized,
placebo-controlled
trial
of
lesinurad
added
to
allopurinol in
patients not reaching sUA target with allopurinol alone; North America
Combination Study of Lesinurad in Allopurinol Standard of Care Inadequate Responders
(CLEAR #2)
randomized,
placebo-controlled
trial
of
lesinurad
added
to
allopurinol in
patients not reaching sUA target with allopurinol alone; Global
Lesinurad Monotherapy in Gout Subjects Intolerant to Xanthine Oxidase Inhibitors (LIGHT) –
randomized, placebo-controlled trial of lesinurad monotherapy in patients where febuxostat
and/or allopurinol
are
contraindicated
(due
to
intolerance,
drug
interactions,
co-morbidities,
etc); Global
Combination Treatment Study in Subjects with Tophaceous Gout Using Lesinurad and
Febuxostat (CRYSTAL)
randomized,
placebo-controlled
trial
of
lesinurad
in
combination
with febuxostat for the treatment of hyperuricemia in gout patients with tophi (resolution of
tophi is a key secondary endpoint); Global

(LASSO

&
Global)
Population:
Up
to
2500
pts
with
hyperuricemia
(sUA
>
8
mg/dL)
at
~300
centers
Design:
Provide therapy with allopurinol at the medically appropriate doses; monitor patients
for a minimum of 2 months prior to their being eligible for enrollment into Phase 3
program (~3 months or greater on allopurinol prior to Phase 3 baseline)
Objectives:
Generate patients for the Phase 3 program with well-documented inadequate
efficacy or intolerance
to
allopurinol
(ultimately
will
speed
up
enrollment
of
Phase 3
program)
