Resumen

This was a Phase 3, multicenter, randomized, double-blind, placebo-controlled trial designed to evaluate the efficacy and safety of the human anti-tumor necrosis factor (TNF) monoclonal antibody adalimumab (ADA) in patients with moderately to severely active ulcerative colitis (UC).

Descripción detallada

This was a Phase 3, multicenter, randomized, double-blind, placebo-controlled trial designed to evaluate the efficacy and safety of adalimumab (ADA) in patients with moderately to severely active ulcerative colitis (UC). The duration of the study was up to 65 weeks, including a Screening Period of up to 3 weeks, a double-blind (DB) placebo-controlled treatment period of up to 52 weeks, and a 70 day follow-up phone call for participants who prematurely discontinued or who did not enroll in the extension study NCT# 00573794 (M10-223). Adult participants with moderate to severe UC (Mayo score of 6 to 12 points with endoscopy subscore of 2 to 3 points), confirmed by colonoscopy with biopsy or flexible sigmoidoscopy with biopsy, were to be enrolled at approximately 120 sites worldwide. Planned enrollment was 500 participants. Participants were to be stratified by prior exposure to infliximab and/or other anti-TNF agents, and randomized in a 1:1 ratio to receive ADA or placebo by subcutaneous injection. Participants assigned to the ADA treatment arm were to receive an induction dose of 160 mg at Week 0 and 80 mg at Week 2, and 40 mg every other week (eow) starting at Week 4. Participants assigned to the placebo treatment arm were to receive matching placebo during the same period of time. At or after Week 10, participants who met the criteria for inadequate response could be switched to open-label (OL) ADA 40 mg eow beginning at Week 12. Inadequate response was defined as: * Partial Mayo score greater than or equal to Baseline score on 2 consecutive visits at least 14 days apart (for participants with a partial Mayo score of 4 to 7 at Baseline). * Partial Mayo score greater than or equal to 7 on 2 consecutive visits at least 14 days apart (for participants with a partial Mayo score of 8 or 9 at Baseline). Participants who demonstrated inadequate response at 2 consecutive visits at least 14 days apart while on OL administration ADA 40 mg eow were permitted to dose escalate to ADA 40 mg weekly (ew). Participants with persistent inadequate response while on ADA 40 mg ew may have been discontinued from the study at the Investigator's discretion. Upon completion of the study, participants had the option to enroll into the OL extension Study M10-223 in which they could receive ADA treatment. Efficacy and safety measurements were performed throughout the study. A follow-up phone call was made 70 days after the last dose of study drug to obtain information on any ongoing or new adverse events (AEs) for all participants who terminated early or who did not enroll in the OL extension study.

Participants \>=18 years of age and in good health (Investigator discretion) with a recent stable medical history
Diagnosis of UC for greater than 90 days prior to Baseline
Diagnosis of active UC confirmed by colonoscopy with biopsy or flexible sigmoidoscopy with biopsy during the Screening Period, with exclusion of infection
Active UC with a Mayo score of 6 to 12 points and endoscopy subscore of 2 to 3 points, despite concurrent treatment with at least 1 of the following (oral corticosteroids or immunosuppressants or both as defined below):
Stable oral corticosteroid dose (prednisone \>= 20 mg/day or equivalent) for at least 14 days prior to Baseline or maintenance, corticosteroid dose (prednisone \< 20 mg/day or equivalent) for at least 40 days prior to Baseline
and/or
At least a 90 day course of azathioprine (AZA) or 6-mercaptopurine (6-MP) prior to Baseline, with a dose of AZA \>= 1.5 mg/kg/day or 6-MP \>= 1 mg/kg/day (rounded to the nearest available tablet formulation), or a dose that is the highest tolerated by the participant (e.g., due to leukopenia, elevated liver enzymes, nausea) during that time. Participant must be on a stable dose for at least 28 days prior to Baseline.
Concurrent therapy was not required for participants who were previously treated with corticosteroids or immunosuppressants (AZA or 6-MP) during the past 5 years and in the judgment of the Investigator have failed to respond to, or could not tolerate, their treatment.
Participants may have been included if they had previously used an anti-tumor necrosis factor (TNF) agent (except ADA) and discontinued its use due to a loss of response or intolerance to the agent.
Had to be able to self-administer or had caregiver who could reliably administer subcutaneous (SC) injections.
Had to be able and willing to give written informed consent and to comply with the requirements of the study protocol.
Female had to be either not of childbearing potential, defined as postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy), or of childbearing potential and practicing an approved method of birth control throughout the study and for 150 days after the last dose of study drug. Examples of approved methods of birth control included the following:
Condoms, sponge, foams, jellies, diaphragm, or intrauterine device
Oral, parenteral, intravaginal contraceptives for 90 days prior to study drug administration
A vasectomized partner The results of the serum pregnancy test performed at the Screening Visit and urine pregnancy test performed at the Baseline Visit must have been negative.
Judged to be in generally good health as determined by the Investigator
