E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate whether sustained trough levels of IFX can be achieved using IFX trough level measurements and adjustment of dosing based upon these levels by means of two different standardized algorythms in comparison with ‘standard of care’ IFX treatment and its effects on clinical and endoscopic outcomes |
Het doel van het onderzoek is het vergelijken van de effectiviteit van de behandeling met infliximab, bij patiënten die behandeld worden volgens de standaard versus patiënten die behandeld worden op geleide van de bloedspiegels. |
|
E.2.2 | Secondary objectives of the trial |
• Clinical remission (CDAI <150) at each visit and the whole study period
• Endoscopic evaluation at week 0, 12 and 54
|
Effect van de behandeling wordt bepaald aan de hand van steroïden-vrije remissie (na week 26), daarbij mucosale heling bij endoscopie op week 54 en uitblijven van chirurgie gedurende het hele jaar. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Age > 18 years
- Active CD (CDAI>220) and signs of active inflammation as evidenced by elevated serum hsCRP levels (>5 mg/L) and/or elevated fecal calprotectin levels (>250 µg/g) and endoscopically visible ulcers.
- Patients must be naïve to biologics with indication for starting anti-TNF therapy in accordance with national reimbursement criteria.
- Patients must be naïve to thiopurines or have failed therapy with thiopurines (in which case AZA will be continued).
- Ongoing steroids are allowed if at stable dose for at least 2 weeks and at a maximum of prednisone 40 mg/d or budesonide 9 mg/day.
- Patients who consent to receiving Infliximab 5 mg/kg at week 0, 2 and 6 and further on every 8 weeks in conjunction with azathioprine (2,5 mg/kg/day). Patients who develop AZA intolerance during the trial are continued in the trial without AZA (ie IFX monotherapy).
|
Leeftijd >18 jaar,
Actieve ziekte van Crohn (CDAI>220) en tekenen van actieve ontsteking bewezen voor verhoogd serum CRP (>5mg/L) en/of verhoogd fecale calprotectine waarde (>250 mcg/g) EN endoscopisch zichtbare ulceraties,
Patiënten naïef voor biologicals met een indicatie tot het starten met anti-TNF therapie overeenkomstig met de landelijk geldende vergoedingsvoorwaarden |
|
E.4 | Principal exclusion criteria |

- Positieve faeces kweken voor Salmonella, Shigella, Yersinia and Campylobacter en/of aanwezigheid van Clostridium difficile B toxine in de ontlasting
- Actieve tuberculose
- Onbehandelde latente tuberculose
