Humira (adalimumab) Receives FDA Approval to Treat Pediatric Patients Living with Moderately to Severely Active Ulcerative Colitis

NORTH CHICAGO, Ill., Feb. 24, 2021 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that the U.S. Food and Drug Administration (FDA) approved Humira (adalimumab) for the treatment of moderately to severely active ulcerative colitis in pediatric patients 5 years of age and older. In clinical trials, Humira induced clinical remission at Week 8 and maintained remission at Week 52 in patients who responded at Week 8.1,2

"Ulcerative colitis can have a profound effect on children and for too long, treatment options for pediatric patients have been limited," said Brandee Pappalardo, vice president and head of U.S. immunology medical affairs, AbbVie. "This approval provides the first and only subcutaneous biologic for pediatric patients with ulcerative colitis that can be administered at home. This new indication for Humira demonstrates AbbVie's commitment to patients with inflammatory bowel diseases and reinforces our goal of reducing the burden of this disease for patients."

This approval is based on results from the pivotal Phase 3 ENVISION I study, which showed that Humira achieved the co-primary endpoints of clinical remission per Partial Mayo Score (PMS) at Week 8 and, among those who responded at Week 8, clinical remission per Full Mayo Score (FMS) at one year (52 weeks).1,2 Clinical remission was defined as a PMS or as a FMS less than or equal to two and no individual sub-score greater than one.1,2

"Ulcerative colitis is unpredictable and affects everyone, especially children, in different ways," said Marla Dubinsky, M.D., chief, Division of Pediatric Gastroenterology for the Mount Sinai Health System and co-director of the Susan and Leonard Feinstein IBD Center at Mount Sinai.* "In the ENVISION I study, Humira provided clinical response as early as Week 8, and many who achieved partial Mayo score response at Week 8 achieved clinical remission at Week 52, per FMS. As a clinician, I am excited to have a new treatment option available and am encouraged by these positive results, which have the potential to help pediatric patients and their caregivers manage their disease."

Ulcerative colitis is characterized by inflammation of the large intestine with symptoms ranging from mild to severe bowel urgency and bowel incontinence as well as weight loss and fatigue.3,4 It remains a lifelong condition that is not adequately controlled in many patients, underscoring the need for more treatment options.3,4 Significant unmet needs remain in moderate to severe pediatric ulcerative colitis, compared to adults, as pediatric patients tend to have more extensive disease often causing significant morbidity in children.4,5

About the ENVISION I Phase 3 Study1,2,6

The ENVISION I study was a Phase 3, randomized, double-blind, multicenter study designed to evaluate the efficacy, safety and the pharmacokinetics of Humira in pediatric patients (ages 4-17) with moderate to severe ulcerative colitis (defined as a FMS of 6 to 12 with endoscopy subscore of 2 to 3 points, confirmed by centrally read endoscopy), administered subcutaneously. 

Through Week 8, patients in both dosage groups received 2.4 mg/kg (maximum of 160 mg) at Week 0, 1.2 mg/kg (maximum of 80 mg) at Week 2, and 0.6 mg/kg (maximum of 40 mg) at Weeks 4 and 6. The higher dosage group also received an additional dosage of 2.4 mg/kg (maximum of 160 mg) at Week 1. Between Week 8 and Week 52, patients received double-blind placebo, Humira 0.6 mg/kg (maximum of 40 mg) every other week, or every week. The co-primary endpoints of the study were clinical remission per PMS (defined as PMS ≤ 2 and no individual subscore > 1) at Week 8, and clinical remission per the Mayo Score (defined as Mayo Score ≤ 2 and no individual subscore > 1) at Week 52 in patients who achieved clinical response per PMS at Week 8. 

Study results demonstrated 60 percent [28/47] of patients taking the higher dosage of Humira achieved clinical remission per PMS, at the end of the 8-week induction period and 43 percent [13/30] of patients in the lower dosage group. At Week 52, among Week 8 PMS responders, 45 percent [14/31] of patients receiving the higher dosage of Humira achieved remission per FMS and 29 percent [9/31] of patients taking the lower dosage of Humira and 33 percent [4/12] of those randomized to placebo. There are limitations to the interpretability of the placebo data due to the small sample size.

Approved dosing for Humira will be determined based on the child's weight, as follows1:

Pediatric
Weight

Recommended Dosage

 

Days 1 – 15

Starting on Day 29


20 kg (44
lbs) to < 40
kg (88 lbs)

  • Day 1: 80 mg
  • Day 8: 40 mg
  • Day 15: 40 mg
  • 40 mg every other week

Or

  • 20 mg every week


≥ 40 kg (88
lbs)

  • Day 1: 160 mg (as single
    dose or split over two
    consecutive days)
  • Day 8: 80 mg
  • Day 15: 80 mg
  • 80 mg every other week

Or

  • 40 mg every week


It is recommended to continue the recommended pediatric dosage in patients who turn 18 years of age and who are well-controlled on their Humira regimen.

In the ENVISION I study, no new safety signals for HUMIRA were observed.1,2 Throughout any Humira exposure in the study, 22.6 percent of patients experienced a serious adverse event.1,2 The most frequently reported (greater than or equal to 5 percent) treatment-emergent adverse events during induction and maintenance periods were headache and worsening of ulcerative colitis.6 No deaths, malignancies, active tuberculosis or demyelinating disease were observed in this study.1,2
