Clinical trial
Multicenter, Randomized, Double-blind, Parallel-group Study of Intra-erythrocyte Dexamethasone Versus Placebo in Patients With Steroid-dependent Crohn's Disease
Name
Crodex01
Description
Primary objective:
Assessment of the efficacy of EryDex vs PLACEBO in maintaining patients with steroid-dependent Crohn's disease in clinical remission throughout 12 months without oral steroids.
Secondary objectives:
1. safety of EryDex
2. emergence of new adverse effects from steroids or disappearance of those possibly pre-existing in the various subgroups of patients;
3. duration of the period of remission;
4. evaluation of the hypophysis-adrenal function;
5. study of plasma concentrations of dexamethasone;
6. effect of therapy on the metabolism of calcium and on indexes of inflammation;
7. assessing the quality of life;
8. rate of surgical resection
9. evaluation of the indirect costs of care.

Eligibility criteria
Inclusion Criteria:
1. Male and female subjects;
2. Age \> 18 years;
3. Patients with steroid-dependent Crohn's disease, documented in the medical history, having suffered from at least one episode of relapse (CDAI \> 150) in the last 12 months. Patients should have been in clinical remission (CDAI \< 150) for at least four weeks, on stable therapy with at least 10 mg of methylprednisolone (or equivalent), or been on steroidal tapering after a recent relapse. Patients with intolerance or resistance to AZT/6-MP/MTX were eligible;
4. Patients willing and able to give written informed consent.
Exclusion Criteria:
1. Patients with Crohn's disease with intestinal sub-occlusion, or suspect of abdominal abscess, or with active perianal disease, or with clinically active disease at randomization (CDAI ≥150);
2. Patients already on therapy with immunosuppressant agents (AZT, 6-MP, MTX) for less than 4 months;
3. Patients having received therapy with infliximab (or other anti-TNF) in the previous 3 months;
4. Investigational treatments in the previous 3 months prior to randomization;
5. Pregnant women, or women who were not using valid birth-control measures, except those in surgical menopause; breast feeding;
6. Non collaborating subjects or those unable to be compliant with the treatment and the study schedules;
7. Severe concomitant diseases such as :
1. patients with inadequate "bone marrow reserve": WBC \< 3000 /mm3; PLTs \< 75000 /mm3; Hb \< 8 g/dl
2. liver disease with total bilirubin ≥ 3 times the upper limit of normal (ULN), AST (GOT) ≥ 3x ULN, alkaline phosphatase ≥ 3x ULN
3. renal disease with serum creatinine ≥ 3 mg/dl
4. serious cardiac, allergic, lung, neurological diseases, neoplastic or pre-neoplastic disease
5. diseases (other than Crohn's) requiring chronic steroid treatment;
8. Elective surgery already scheduled at the start of the study (NB: patients having undergone previous surgery for Crohn's disease could be enrolled, if the patient had fully recovered and had been in remission for at least 4 weeks);
9. Chronic use of alcohol; drug addiction;
10. Subjects with contra-indication to the use of steroids (i.e. systemic fungal infections);
11. Evidence of clostridium difficilis in the stools.
