Brief summary of the study: English

The rationale for this study, SHP647-304, is to offer access to active treatment to subjects who may have benefited from the treatment at the end of the maintenance study (SHP647-303 or SHP647-307) or to subjects who had received placebo or an insufficient duration of active treatment in an induction study (SHP647-302, or SHP647-306) or have met treatment failure criteria in a maintenance study (SHP647-303 or SHP647-307), while evaluating safety and efficacy of long-term treatment with SHP647 in subjects with moderate to severe UC or CD.

Brief summary of the study: Arabic

لأساس المنطقي لهذه الدراسة ، SHP647-304 ، هو توفير الوصول إلى العلاج النشط للمواضيع الذين قد استفادوا من العلاج في نهاية الدراسة الصيانة (SHP647 أو SHP647-307) أو إلى الأشخاص الذين تلقوا الغفل أو مده غير كافيه من العلاج النشط في الدراسة التعريفية (SHP647-302 ، أو SHP647-306) أو قد استوفت معايير فشل العلاج في دراسة الصيانة (SHP647-303 أو SHP647-307) ، في حين تقييم سلامه وفعالية العلاج علي المدى الطويل مع SHP647 في المواضيع مع معتدله إلى UC أو CD شديده.

Health conditions/problem studied: Specify

Moderate to Severe Ulcerative Colitis or Crohn Disease

Interventions: Specify

All subjects will receive active drug in this study. Eligible subjects entering study SHP647-304 will be assigned to receive either 25 mg or 75 mg of SHP647 every 4 weeks. Allocation is dependent on how the subject entered into this study: Subjects who completed maintenance study SHP647-303 or SHP647-307 without treatment failure and received either 25 mg or 75 mg of SHP647 every 4 weeks will continue to receive the same dose of SHP647 in this long-term safety extension study. If results for confirmation of treatment failure are pending at the time of the end of study visit in study SHP647-307, sites will have 1 additional week to confirm final status of the subject (treatment failure or not) before enrolling the subject to study SHP647-304. All other subjects will be randomized using a 1:1 allocation. Randomization will be stratified by indication (UC or CD) and by the status from the study from which they are entering, as follows: (1) did not meet the response criteria (clinical and/or endoscopic response/remission as appropriate) in an induction study; (2) treatment failure in a maintenance study, or (3) maintenance study completion without treatment failure for subjects receiving placebo, to facilitate balance of treatment assignment within each stratum.

Key inclusion and exclusion criteria: Inclusion criteria

Ulcerative Colitis: 1. Subjects and/or their parent or legally authorized representative must have an understanding, ability, and willingness to fully comply with study procedures and restrictions. 2. Subjects must be able to voluntarily provide written, signed, and dated (personally or via a legally authorized representative) informed consent and/or assent, as applicable, to participate in the study. 3. Subjects must have been previously enrolled in study SHP647-302, or SHP647-303, and reached 1 of the following clinical trial milestones: - Completed the Week 12 visit in induction study SHP647-302, and did NOT achieve a clinical response. Clinical response is defined as: 1) a decrease from baseline in the composite score of patient-reported symptoms using daily e-diary and centrally read endoscopy of at least 2 points and at least 30%, with an accompanying decrease in the subscore for rectal bleeding ≥1 point or a subscore for rectal bleeding ≤1, OR 2) a decrease from the induction study (SHP647-302) baseline total Mayo score of at least 3 points and at least 30%, with an accompanying decrease in the rectal bleeding subscore of at least 1 point or an absolute rectal bleeding subscore of 0 or 1. - Completed the Week 52 visit in maintenance study SHP647-303. - Withdrew early from maintenance study SHP647-303 due to treatment failure, defined by an endoscopic subscore that has increased by at least 1 point over baseline in the maintenance study or a value ≥2 plus an increase in clinical subscore (stool frequency + rectal bleeding score) of at least 2 points. Centrally read endoscopic subscores will be used to determine treatment failure. 4. Subjects receiving any treatment(s) for UC described in Section 5.2.1 are eligible provided they have been, and are anticipated to be, on a stable dose for the designated period of time. Crohn's Disease: 1. Subjects and/or their parent or legally authorized representative must have an understanding, ability, and willingness to fully comply with study procedures and restrictions. 2. Subjects must be able to voluntarily provide written, signed, and dated (personally or via a legally authorized representative) informed consent and/or assent, as applicable, to participate in the study. 3. Subjects must have been previously enrolled in study SHP647-306, or SHP647-307, and reached 1 of the following clinical trial milestones: • Completed the Week 16 visit in induction study SHP647-306, and did NOT meet the efficacy criteria (clinical and/or endoscopic response/remission as appropriate) for entry into maintenance study SHP647-307. • Completed the Week 52 visit in maintenance study SHP647-307. • Withdrew early from maintenance study SHP647-307 due to treatment failure (or were considered to have failed treatment, at the time of the last visit in study SHP647-307), as defined in the SHP647-307 protocol. 4. Subjects receiving any treatment(s) for CD described in Section 5.3.1 are eligible provided they have been, and are anticipated to be, on a stable dose for the designated period of time.

Therapeutic benefit

Efficacy will be assessed regularly for all subjects to allow monitoring of clinical benefit derived and evaluation of potential treatment failure throughout the study. To ensure that placebo-treated subjects from a feeder study (SHP647-302, SHP647-303, SHP647-306, or SHP647-307) have sufficient exposure to active drug to permit assessment of response, assessment of treatment failure should not begin prior to Week 12 (for UC) or Week 16 (for CD). Treatment failure should be assessed if there is an unexplained clinical exacerbation or unacceptably low level of clinical response.
