Background
Ustekinumab is a human, monoclonal antibody that binds to the shared p40 subunit of interleukins 12 and 23 and, therefore, inhibits binding to their receptors. In Phase 2 and Phase 3 (PHOENIX 1 and 2) psoriasis studies, ustekinumab therapy has been shown to be highly efficacious in treating patients with moderate to severe psoriasis with a favor-able benefit/risk profile.1,2,3
Objectives
To analyze the cumulative safety experience with up to 76 weeks of treatment (referred �
to as the 1.5-Year Safety Analysis) with ustekinumab across Phase 2 and 3 psoriasis clinical trials
To analyze selected adverse events of interest (i.e., serious infections, malignancies �
and cardiovascular events) in recently locked data with up to 152 weeks of treatment (referred to as the 3-Year Safety Analysis)
Methods
To evaluate the safety of ustekinumab in the overall psoriasis clinical development �
program, safety data was pooled data across psoriasis Phase 2 and Phase 3 stud-ies on two separate occasions based on all data available at the time of the analyses (referred to as 1.5-Year Safety Analyses and 3-Year Safety Analyses).
The 1.5-Year Safety Analyses (n=2266) occurred based on all data available in data- �
base locks that occurred through October 2007, including:
36 weeks of data from the C0379T04 placebo-controlled Phase 2 trial —
76 weeks of data from the PHOENIX 1 placebo-controlled Phase 3 trial —
52 weeks of data from the PHOENIX 2 placebo-controlled Phase 3 trial —
The 3-Year Safety Analyses (n=3117) occurred based on all data available in data- �
base locks that occurred through May 2009, including:
36 weeks of data from the C0379T04 placebo-controlled Phase 2 trial —
152 weeks of data from the PHOENIX 1 placebo-controlled Phase 3 trial —
100 weeks of data from the PHOENIX 2 placebo-controlled Phase 3 trial —
64 weeks of data from the ACCEPT Phase 3 trial comparing ustekinumab and —etanercept safety and efficacy
Cumulative safety was evaluated during the placebo-controlled period (12- 20 weeks), �
with up to 1.5 years of treatment, and with up to 3 years of treatment. Serious infec-tions and infections requiring antibiotics, malignancies, and major adverse cardiovas-cular events were evaluated as adverse events (AE) of special interest.
Event rates were compared with what would be expected with psoriasis or the gen- �
eral population using external databases: serious infection (Marketscan database), solid tumors (SEER database), and myocardial infarction (MI)/stroke (Framingham database)

Adverse Events of Special InterestAdverse events of special interest, including serious infections and infections requir- �
ing antibiotics, malignancies, and major adverse cardiovascular events were reviewed by 3 cumulative periods: placebo controlled period (12- 20 weeks), through the con-trolled and uncontrolled periods at both 1.5 years and 3 years (Figures 2, 3, 4, 5, 6)
Overall, rates of serious infection, serious cardiovascular events, and malignancy �
adjusting for follow-up did not increase with time or duration of ustekinumab expo-sure for up to 3 years (Figures 2, 3, 4, 5, 6)
Serious Infections and Infections Requiring Antimicrobial TreatmentDuring the controlled period, serious infection rates were 1.70/100 patient-years (PY) �
for placebo compared with 0.49/100 PY and 1.97/100 PY for ustekinumab 45 and 90 mg dosing, respectively (Figure 2)
In the 1.5- and 3-year analyses, rates of serious infections and infections requiring �
antibiotics remained stable with increasing duration of exposure
Rates of serious infection observed in this trial were consistent with rates expected in the �
psoriasis population using the Marketscan Database. For the combined ustekinumab group:
Expected event rate per 100 patient-years (95% CI)= 1.51 (1.18-1.90) —
Observed event rate per 100 patient-years (95% CI)= 1.19 (0.90-1.54) —

Limitation
The lack of placebo control group beyond 12 weeks for the phase 3 trials and 20 weeks �

Conclusions
The ustekinumab psoriasis clinical safety database is large with over 3000 patients �
treated for up to 3 years
Adverse event rates remained stable through 3 years without evidence of cumulative �
toxicity.
These analyses support a favorable benefit/risk profile for ustekinumab with up to �
3 years of treatment, a profile which will continue to be elucidated in 2 ongoing Phase 3 studies.

Adverse Events of Special InterestAdverse events of special interest, including serious infections and infections requiring antibiotics, malignan-JJ
cies, and major adverse cardiovascular events were reviewed by 3 cumulative periods: placebo controlled period (12- 20 weeks), through the controlled and uncontrolled periods at both 1.5 years and 3 years (Figures 2, 3, 4, 5, 6)
Overall, rates of serious infection, serious cardiovascular events, and malignancy adjusting for follow-up did JJ
not increase with time or duration of ustekinumab exposure for up to 3 years (Figures 2, 3, 4, 5, 6)
Serious Infections and Infections Requiring Antimicrobial TreatmentDuring the controlled period, serious infection rates were 1.70/100 patient-years (PY) for placebo compared JJ
with 0.49/100 PY and 1.97/100 PY for ustekinumab 45 and 90 mg dosing, respectively (Figure 2)
In the 1.5- and 3-year analyses, rates of serious infections and infections requiring antibiotics remained JJ
stable with increasing duration of exposure
Rates of serious infection observed in this trial were consistent with rates expected in the psoriasis popula-JJ
tion using the Marketscan Database. For the combined ustekinumab group:
Expected event rate per 100 patient-years (95% CI)= 1.51 (1.18-1.90) —
Observed event rate per 100 patient-years (95% CI)= 1.19 (0.90-1.54) —

MalignanciesDuring the controlled period, non-melanoma skin cancer (NMSC) and non-NMSC malignancies (all malig-JJ
nancies including melanoma and lymphoma) did not occur at higher rates with ustekinumab than with pla-cebo (Figure 4, 5)
In the 1.5- and 3-year analyses, rates of both NMSC and non-NMSC malignancies remained low and were JJ
stable with increasing duration of exposure
Rates for non-NMSC malignancies observed in these trials over 3 years were consistent with rates expected JJ
in the general U.S. population using the SEER Database

Cardiovascular (CV) EventsRates of major adverse CV events, including CV death, myocardial infarction, and stroke, were evaluatedJJ
During the placebo-controlled period, there were no CV events in the placebo group compared to 5 in JJ
the combined ustekinumab-treated patients (3 events in Phase 2 and 2 events in Phase 3) for a rate of 1.23/100 PY (Figure 6)
With extended exposure at both 1.5 and 3 years, rates of major CV events were low and remained stable JJ
without evidence of a dose response.
Rates of MI and stroke observed in these trials were consistent with or lower than the rates expected in the JJ
general population using the Framingham database

Limitation
The lack of placebo control group beyond 12 weeks for the Phase 3 trials and 20 weeks for the Phase 2 JJ
trial limits the comparisons of these analyses of rare events

Conclusions
The ustekinumab psoriasis clinical safety database is large with over 3000 patients treated for up to JJ
3 years
Adverse event rates remained stable through 3 years without evidence of cumulative toxicity.JJ
These analyses support a favorable benefit/risk profile for ustekinumab with up to 3 years of treatment, a JJ
profile which will continue to be elucidated in 2 ongoing Phase 3 studies.
