What is the likelihood of clinical remission with Rinvoq (upadacitinib) in a biologic-naive patient with moderate to severe ulcerative colitis?

Likelihood of Clinical Remission with Rinvoq (Upadacitinib) in Biologic-Naive Ulcerative Colitis Patients

Approximately 49% of biologic-naive patients with moderate-to-severe ulcerative colitis achieve clinical remission with upadacitinib induction therapy, making it the most effective advanced therapy available for this population. 1

Evidence-Based Remission Rates

Induction Therapy (8 Weeks)

• Upadacitinib 45 mg once daily achieves clinical remission in approximately 49% of biologic-naive patients, compared to a 10% placebo rate, representing an absolute benefit of 39% 1
• In the pivotal U-ACHIEVE and U-ACCOMPLISH trials, clinical remission rates were 26% and 34% respectively, with placebo rates of only 4-5%, yielding absolute benefits of 22-29% 1, 2
• The American Gastroenterological Association network meta-analysis ranked upadacitinib highest (P score 0.96) for inducing clinical remission among all advanced therapies in biologic-naive patients 1

Comparative Efficacy Context

• Upadacitinib demonstrates moderate-certainty evidence of clinically important benefit over infliximab, adalimumab, etrasimod, ustekinumab, mirikizumab, tofacitinib, and filgotinib 1
• Low-certainty evidence suggests superiority over golimumab, vedolizumab, and guselkumab 1
• For comparison, other first-line options achieve lower remission rates: risankizumab 35%, ozanimod 35%, guselkumab 27%, infliximab 26%, and golimumab 26% 1

Maintenance Therapy Outcomes (52 Weeks)

Sustained Remission Rates

• Among patients who respond to 8-week induction, 42% maintain clinical remission with upadacitinib 15 mg daily and 52% with 30 mg daily at 52 weeks, compared to 12% with placebo 3, 2
• The absolute treatment differences are substantial: 30.7% for 15 mg (95% CI 21.7-39.8) and 39.0% for 30 mg (95% CI 29.7-48.2) versus placebo 1, 3
• Both maintenance doses demonstrate superiority over risankizumab with low-certainty evidence (RR 2.83 for 30 mg, RR 2.32 for 15 mg) 1

Extended Induction for Non-Responders

Additional Treatment Opportunity

• Among the 19.2% of patients who do not achieve clinical response at 8 weeks, an additional 8 weeks of upadacitinib 45 mg results in clinical response in 59.1% 4
• Of these extended induction responders, 26.5% achieve clinical remission with 15 mg maintenance and 43.6% with 30 mg maintenance at 52 weeks 4

Real-World Evidence

Effectiveness in Clinical Practice

• Real-world meta-analysis of 1,388 patients (94% with prior biologic failure) demonstrated clinical remission in 68.4% at week 8 (95% CI 55.5-80.2) 5
• Clinical response rates in real-world settings: 72.6% at weeks 2-6,82.1% at week 8, and 78.7% at weeks 12-16 5
• Importantly, upadacitinib effectiveness appears unaffected by prior biologic or JAK inhibitor failure, suggesting robust efficacy even in treatment-experienced populations 5

Regulatory and Safety Considerations

FDA Positioning Restrictions

• In the United States, FDA requires documented TNF antagonist failure or contraindication before using upadacitinib, based on cardiovascular safety data from rheumatoid arthritis populations 1, 6
• Outside the US, upadacitinib can be considered first-line in select biologic-naive patients 6, 7

Critical Safety Monitoring

• Black box warning for serious infections, malignancies, major adverse cardiovascular events, and thrombosis 6
• Do not use as first-line therapy in patients ≥65 years with cardiovascular risk factors when TNF inhibitors remain viable 6
• Herpes zoster vaccination should be considered before initiation, particularly in patients aged >70 years or >50 years at high risk 6

Endoscopic and Biochemical Outcomes

Mucosal Healing

• Upadacitinib demonstrates superior endoscopic improvement rates compared to all other advanced therapies in biologic-naive patients with moderate-certainty evidence 7
• Mean fecal calprotectin decreased from 1485.0 µg/g at baseline to 454.8 µg/g post-treatment (p < 0.01) 5
• Mean CRP decreased from 12.3 mg/L to 4.4 mg/L post-treatment (p = 0.02) 5

Clinical Decision Algorithm

For biologic-naive patients in the United States:

• First-line: Risankizumab or ozanimod (35% remission rate) due to FDA restrictions 1, 7
• After TNF antagonist failure: Upadacitinib 45 mg induction (49% remission rate) 1, 6

For biologic-naive patients outside the United States:

• Upadacitinib can be considered first-line for highest efficacy (49% remission rate) 6, 7
• Avoid in patients ≥65 years with cardiovascular risk factors 6
• Avoid in current/past smokers with cardiac disease 6
