|
E.1.1.2 | Therapeutic area | Diseases [C] - Digestive System Diseases [C06] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to analyse the number of patients
that need a re-intervention due to fistula-related complications
(abscesses, recurrent or new tract formation).
E.2.2 |
|
E.2.2 | Secondary objectives of the trial |
The secondary outcomes parameters will be the number of patients with
closed fistulas (based on MRI findings) after 18 months, Perianal
Disease Activity Index (PDAI score) and number of necessary antibiotics
courses during fistula treatment, quality of life (EQ-5D and IBDQ), and costs (KEA and BIA) |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- ≥ 18 years
- Written informed consent
- High tract (intersphincteric, transsphincteric, suprasphincteric)
perianal fistula located in the upper
two-thirds of the external sphincter
- Fistula with one internal opening (based on MRI imaging). The number
of external fistulas does not
have to be taken into account
- Both new fistulas or recurrent active fistula (defined as any producing
fistula)
|
|
E.4 | Principal exclusion criteria |
- Proctitis (defined as any active mucosal inflammation or ulcer > 5mm
in the rectum)
- Anorectal stenosis (defined as the impossibility to introduce a
proctoscope)
- Submucosal fistulas & low intersphincteric fistulas (lower one-third of
external sphincter)
- Rectovaginal fistula
- Multiple internal openings
- Seton in situ for more than 3 months
- Use of Anti-TNF medication during last 3 months
- Previous Anti-TNF medication without any effect on perianal fistulas
- Previously demonstrated allergy for anti-TNF medication. If this allergy
only concerns the chimeric
monoclonal mouse-antibody infliximab, the patient could be
randomised for adalumimab
- Patients with a stoma
- Immunocompromised patients (i.e. haematological malignancies,
HIV/AIDS, bone marrow
transplantation, splenectomy, genetic disorders such as severe
combined immunodeficiency,
chemotherapy, dialysis, solid organ transplant and long term
immunosuppressant use such as
corticosteroids in patients with rheumatoid arthritis)
- Life expectancy < 2 years
- The inability of reading/understanding and filling in the questionnaires
- Dementia or altered mental status that would prohibit the
understanding and giving of informed
consent |

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
12 months after randomization |
|
E.5.2 | Secondary end point(s) |

- Disease activity, as measured with the Perianal Disease Activity Index
(PDAI) score
- Number of sick leave days
- Number of in-hospital days
- Costs (CEA and BIA) |
