Descrizione riassuntiva della sperimentazione (Fonte di dati: BASEC)
Mit dieser Studie soll herausgefunden werden ob Etrolizumab (in zwei verschiedenen Dosen) im Vergleich zu Placebo eine wirksame Behandlung ist.
Die Studie wird in eine Voruntersuchungsphase (4 Wochen), eine Induktionsphase (14 Wochen), eine Erhaltungsphase (60 Wochen) und eine Sicherheitsnachbeobachtungsphase (12 Wochen) eingeteilt.
Bei Studienaufnahme (Induktionsphase) werden Patienten in eine von 3 Kohorten aufgenommen (Zufallsprinzip durch ein Computerprogramm).
Kohorte 1: 300 Patienten werden im Verhältnis 1:2:2 für Placebo, Etrolizumab in niedriger Dosis (105 mg) oder in hoher Dosis (210 mg) zugewiesen.
Kohorte 2: 350 Patienten im Verhältnis 1:1 für Etrolizumab in niedriger Dosis oder in hoher Dosis zugewiesen.
Kohorte 3: 600 Patienten im Verhältnis 2:3:3 für Placebo, Etrolizumab in niedriger Dosis oder in hoher Dosis zugewiesen.
In Woche 14 setzen Patienten aus allen 3 Kohorten, wenn sie auf die Studienbehandlung (laut CDAI) angesprochen haben, die Studie mit dem Erhaltungsabschnitt fort.
Während des Erhaltungsabschnitts erhalten die Patienten alle 4 Wochen eine 105-mg-Dosis, die entweder Etrolizumab oder Placebo enthält.
Nach Verabreichung der letzten Dosis haben die Patienten eine 12-wöchige Sicherheitsnachbeobachtung.
Nonresponder, erhalten die Möglichkeit in die offene Verlängerungsstudie (GA29145, Teil 1) aufgenommen zu werden,
Es kann nicht garantiert werden, dass Patienten einen Nutzen aus der Teilnahme an dieser Studie haben.

Inclusion/Exclusion Criteria
(Fonte di dati: WHO)
Inclusion Criteria:
- Moderately to severely active Crohn's Disease (CD) as determined by the CDAI, patient
reported outcomes and endoscopically defined disease activity in the ileum and/or
colon
- Intolerance, refractory disease, or no response to corticosteroids (CS),
immunosuppressants (IS), or anti-TNF therapy within 5 years from screening.
Participants who have not previously demonstrated inadequate response or intolerance
to one or more anti-TNF therapies are eligible to participate in the study provided
they are intolerant or refractory to CS or IS therapy
- Use of effective contraception as defined by the protocol
Exclusion Criteria:
- A history of, or current conditions affecting the digestive tract, such as ulcerative
colitis, indeterminate colitis, fistulizing disease, abdominal or perianal abscess,
adenomatous colonic polyps not excised, colonic mucosal dysplasia, and short bowel
syndrome
- Planned surgery for CD
- Ileostomy or colostomy
- Has received non-permitted inflammatory bowel disease (IBD) therapies (including
natalizumab, vedolizumab, and efalizumab, as stated in the protocol)
- Any prior treatment with ustekinumab within 14 weeks prior to randomization
- Chronic hepatitis B or C infection, human immunodeficiency virus (HIV), active or
latent tuberculosis (participants with prior history of Bacillus Calmette-Guérin [BCG]
vaccination must pass protocol-defined screening criteria)
- Sinus tract with evidence for infection (e.g., purulent discharge) in the clinical
judgment of the investigator. Fistulas related to CD are not exclusionary
- Any prior treatment with anti-adhesion molecules (e.g., anti-mucosal addressin cell
adhesion molecule [anti-MAdCAM-1])
- Any major episode of infection requiring treatment with intravenous antibiotics =8
weeks prior to screening or oral antibiotics =4 weeks prior to screening. Treatment
with antibiotics as adjunctive therapy for CD in the absence of documented infection
is not exclusionary
- Hospitalization (other than for elective reasons) within 4 weeks prior to
randomization
