Primary Outcome Measures:
  • proportion of patients maintaining steroids-free clinical remission (CDAI<150) without surgery for 12 months [ Time Frame: after 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • evaluation of safety by comparison of treatment emergent AE [ Time Frame: after 12 months ] [ Designated as safety issue: Yes ]
  • proportion of patients interrupting the study because of adverse events [ Time Frame: after 12 months ] [ Designated as safety issue: Yes ]
  • duration of the period of clinical remission [ Time Frame: after 18 months ] [ Designated as safety issue: No ]
  • dosing of serum cortisol [ Time Frame: after 12 months ] [ Designated as safety issue: Yes ]
    basal and following ACTH trigger

  • evaluation of inflammation indexes (ESR, CRP) [ Time Frame: after 12 months ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Experimental: Ery-dex
Ery-dex (dexamethasone sodium phosphate)is administered as intra-erythrocyte drug at monthly interval
Drug: Dexamethasone
500 mg/20 ml encapsulated in erythrocytes, every month for 12 months
Other Name: Ery-dex
Placebo Comparator: Placebo
placebo comparator (sodium chloride instead of dexamethasone sodium phosphate) is administered in infusion at monthly interval.
Drug: Dexamethasone
500 mg/20 ml encapsulated in erythrocytes, every month for 12 months
Other Name: Ery-dex

Detailed Description:

The medical treatment of Crohn's disease is still unsatisfactory despite the use of large number of drugs as steroids which cause several side effects after a long-term treatment.Ery-Dex thanks its peculiar way of administration (intra-erythrocyte encapsulation and release at very low doses during 1 month)should dramatically reduce side effects due steroids, which are dose dependent, and provide an alternative for long-term glucocorticoid therapy.
