Category Projected Advantages of Acelex
Efficacy  ?Quicker onset of relief from the signs and symptoms of OA over celecoxib.  Achieved superior PGA (Physicians Global Assessment) scores compared to celecoxib.
Dose  Only 2 mg/day dose, the lowest daily dose among all known NSAIDs.
Administration Frequency Convenient once-a-day dosing regimen unlike most other NSAIDs.
Gastrointestinal Side Effects  Significantly improved GI safety in comparison with traditional NSAIDs on the market.
Cardiovascular Side Effects  Acelexs tissue-selective-COX2-inhibition mechanism is projected to provide a meaningful enhancement of cardiovascular safety over currently available NSAIDs.
OA Market Characteristics
  • Osteoarthritis (OA) is characterized by
  • deterioration of cartilage tissue within
  • and involves entire joint1
  • Nearby muscles
  • Underlying bone
  • Ligaments
  • Joint lining (synovium)
  • Joint cover (capsule)
  • The cause is still not completely known and there
    is no cure
  • Aging of population is driving growth of OA
  • Cartilage degradation is positively correlated
    with increasing age and is most common in people
    over 55 years of age
  • Obesity epidemic resulting in more wear and tear
    on joints is also contributing to growth of OA

1 Business Insights 2009 The Autoimmune
Outlook to 2013
Positioning of A Novel NSAID, Acelex for
Acelex would be the first, tissue-selective and
once-a-day osteoarthritis drug with a novel
mode of action that specifically targets affected
joints to relieve pain and restores
mobility Acelex 2 mg once-a-day could provide
more rapid onset of relief from the signs and
symptoms of osteoarthritis in comparison with
Celebrex 200 mg once-a-day without added
safety risk.

Tissue Selective COX-2 Inhibitor Acelex (Polmacoxib CG) - Tissue selective COX-2 inhibitor Once/day (2 mg/day) Low None observed to date
Mechanism of Polmacoxib
Polmacoxib, a dual inhibitor of COX-2 and human
CA (carbonic anhydrase), does not inhibit COX-2
in CA-rich tissues (e.g. CV system), but it fully
inhibits COX-2 in CA-deficient tissues (inflamed
Whole Blood, Blood Vessels, CV Tissues
Inflamed Joints (OA, RA)

Phase III Study Study Title The Objectives
Study Title and the Objectives of the Study
Study Title A Double-blind, Randomized,
Multicenter, Active- and Placebo-Controlled Phase
III Study to Evaluate the Efficacy and Safety of
CG100649 in Osteoarthritis Patients Objectives
The objective of the 6-week Efficacy Study was
to evaluate the safety and non-inferiority of
the analgesic efficacy of polmacoxib (formerly
CG100649) 2 mg vs. celecoxib 200 mg, and the
analgesic superiority of polmacoxib 2 mg vs.
placebo, when administered once daily in
subjects with osteoarthritis of the hip or knee
over the 6 week treatment period. The
objective of the Extension Study was to collect a
total of 24 weeks of safety data for those
subjects who agreed to continue into the
Acelex, Phase III Study Results
Acelex showed SUPERIOR EFFICACY over celecoxib
with statistical significance (p 0.005)
71.9 of subjects taking Acelex experienced
improvement in signs and symptoms of
Overall improvement of signs and symptoms
of osteoarthritis in terms of PGA scores at week
PGA (Physicians Global Assessment ) Evaluation
of the test subjects by the investigators
Acelex, Phase III Study Results
Acelex showed QUICKER ONSET OF RELIEF from
osteoarthritis symptoms over celecoxib
Acelex showed statistically significant
superiority over placebo at Week 3 (p0.003), but
celecoxib did NOT show statistically significant
differentiation from placebo at Week 3 (p0.069)

WOMAC Physical Function scores at Week 3
Acelex demonstrated non-inferior or better
efficacy against celecoxib in all other efficacy
endpoints including WOMAC-pain and stiffness
subscales at week-3 and week-6
Phase III Study Safety (6-week Treatment Period)
Safety Results from the 6-week Efficacy Study
  • There were no drug-related serious adverse events
    in either of the polmacoxib or
    celecoxib treatment groups.
  • Most of the adverse events were mild to moderate
    and were expected to happen in this type of
  • There were no statistically significant
    differences in all three groups.

Phase III Study Conclusions (6-week Treatment
Polmacoxib has successfully met the clinical
study endpoints as the 2 mg dose of polmacoxib
was tolerated well and based on the results of
the 6-week treatment period, polmacoxib 2 mg
demonstrated analgesic efficacy and safety
similar to that of celecoxib 200 mg, and
analgesic superiority over that of placebo.
However, based on the secondary endpoints of
WOMAC-Physical function at Week 3 and PGA at Week
3, the efficacy profile of polmacoxib was
superior in comparison with celecoxib. This
suggests that polmacoxib 2 mg achieves a quicker
onset of relief from the signs and symptoms of
osteoarthritis compared to celecoxib 200 mg. The
Treatment Emergent Adverse Events (TEAEs) were
reported in this study were generally mild and of
the type expected for COX-2 inhibitor drugs.
There were no clinically meaningful or
statistically significant differences in the
number of TEAEs among the groups treated with
polmacoxib 2 mg, celecoxib 200 mg or placebo.
Phase III Study Extended Safety Study
Safety Conclusions from Safety Extension Study
(24 weeks) Only polmacoxib 2mg administered
(open-label, single arm)
  •  There were no drug-related serious adverse
  •  During the safety extension study, the 2mg dose
    of polmacoxib was tolerated well
  • and TEAEs were generally mild.
  •  There were no notable increases in the incidence
    of any TEAEs during the 18-week
  • safety extension period, or the combined
    24-week extended safety period.
  •   There were no clinically relevant findings in
    the analysis of clinical laboratory tests,
  • vital signs, ECGs, or physical examination

Product Profile of Acelex
Category Projected Advantages of Acelex
Efficacy  ?Demonstrated quicker onset of relief from the signs and symptoms of OA over Celebrex.  Achieved superior PGA (Physicians Global Assessment) scores, than Celebrex with statistically significance, an efficacy endpoint for measuring the physicians perception of patient improvement in terms of the OA signs and symptoms.
Dose  Able to achieve therapeutic efficacy (OA) with only 2 mg/day dose, the lowest dose among all known NSAIDs (both non-selective and selective COX-2 inhibitors).
Administration Frequency Convenient once-a-day dosing regimen ? The administration frequencies of most commercially available traditional NSAIDs and incrementally modified NSAID containing products for OA range between b.i.d (twice daily) through t.i.d (three times daily).
Gastrointestinal Side Effects  Acelex has significantly improved GI safety profile in comparison with other commercially available NSAIDs.  The GI safety profile of Acelex eliminates the need for concomitant administration of GI protectant agents.
Cardiovascular Side Effects  Acelexs unique mode of action is projected to provide a meaningful enhancement of cardiovascular safety from currently available NSAID products.
Acelex, Lifecycle Management Strategy
Expansion of Acelex portfolio through
development of combination products,
incrementally modified products, new dosage
forms, and additional indications. Goal is to
maintain exclusive position up to 20262034 and
maximize revenues.
