Significant Clearance with Convenient Dosing*
7 out of 10 patients achieved PASI 75 after only 2 starter doses
PHOENIX 2 evaluated 1230 patients who began the study receiving STELARA® 45 mg or 90 mg or placebo. Patients randomized to STELARA® received STELARA® at Weeks 0 and 4, followed by the same dose every 12 weeks through Week 28. Patients in the placebo group (n=410) crossed over to receive either STELARA® 45 mg or 90 mg at Weeks 12 and 16, followed by the same dose every 12 weeks. Eligible patients were adults with a diagnosis of plaque psoriasis for ≥6 months involving ≥10% Body Surface Area (BSA), PASI score ≥12, and who were candidates for phototherapy or systemic therapy.1, 3
The primary endpoint was PASI 75 at Week 12 (45 mg: 67% [n=409]; 90 mg: 76% [n=411]; placebo: 4% [n=410]; P<0.0001 vs placebo for each dose).1, 3
Treatment success (defined as PGA score of Cleared or Minimal) was achieved at Week 12 in 7 out of 10 patients in the 45 mg and 90 mg groups (68% and 73%, respectively) compared with 4% of placebo patients (P<0.0001).1, 3
PASI 90 was achieved by more than 4 out of 10 patients at Week 12 in the 45 mg and 90 mg groups (42% and 51%, respectively)
compared with 1% of placebo patients (P<0.0001).3§
*STELARA® is a subcutaneous injection dosed once every 12 weeks after 2 starter doses at Weeks 0 and 4.1
§PASI 90 was a prespecified endpoint, not a primary endpoint.
8 out of 10 patients who were rerandomized to continue treatment after responding to STELARA® at Weeks 28 and 40 sustained PASI 75 at Week 100
The safety and efficacy of STELARA® have not been evaluated beyond two years.1
Results from open-label extension at Week 100; concomitant topicals were allowed after Week 76.2
PHOENIX 1 evaluated 766 patients who received STELARA® or placebo. The study design was identical to PHOENIX 2 through Week 28. Inclusion criteria were consistent with PHOENIX 2. At Week 40, patients initially randomized to STELARA® who were PASI 75 responders at both Weeks 28 and 40 were rerandomized either to continue every–12-week dosing with STELARA® or to placebo. Patients randomized to placebo at Week 40 were retreated with their original dosing regimen when they lost ≥50% of the PASI improvement achieved at Week 40. Patients rerandomized to STELARA® at Week 40 were considered treatment failures if they discontinued STELARA® due to unsatisfactory therapeutic effect, experienced an adverse event of worsening of psoriasis, or started non-topical protocol-prohibited medications.1,2
After Week 76, treatment was unblinded, and treatment failure rules were relaxed to allow for use of concomitant topical medications, except for high-potency corticosteroids (10 patients randomized to STELARA® every 12 weeks at Week 40 received concomitant topicals between Week 76 and 100; PASI 75 was achieved in 4 out of 10 of these patients at Week 100).2
The primary endpoint was PASI 75 at Week 12 (45 mg: 67% [n=255]; 90 mg: 66% [n=256]; placebo: 3% [n=255]; P<0.0001 vs placebo for each dose).1, 4
