Study Endpoints
Primary Endpoints
The Proportion of Patients Responders to Dex 21-P vs Placebo
From baseline to End of treatment = 6 weeks ± 10 days (in chronic and steroid dependent IBD patients) or 28 weeks ± 5 days (in mesalazine refractory UC patients)

Patients were considered responder if, at the EoS, one of the following occurred: * Disease remission (Powell Tuck index ≤ 3 or CDAI \< 150) and withdrawal of oral steroids therapy from at least the second treatment procedure; * Disease marked improvement vs basal conditions (at least 5 point decrease in Powell Tuck or 150 point decrease in CDAI score) and withdrawal of oral steroids therapy from at least the second treatment procedure. The Powell-Tuck index was calculated by adding the subscores given by 7 items. A total score \< 10 indicated a mild activity of the UC, and a total score \>14 a severe one. The higher the score the worse the outcome. Crohn Disease Activity Index (CDAI) was a tool that combines subjective parameters, with objectives parameters. The score given to each parameter was inserted in an algorithm which provided the final Index value. A moderate CD showed a CDAI score between 220 and 450, while a CDAI \> 450 was an activity index indicating a severe disease.

Secondary Endpoints
Change From Baseline in Endogenous Cortisole Blood Level After Receiving the Study Treatment
From baseline to End of treatment = 6 weeks ± 10 days (in chronic and steroid dependent IBD patients) or 28 weeks ± 5 days (in mesalazine refractory UC patients)
Change From Baseline in Inflammatory Indexes After Receiving the Study Treatment: Erythrocyte Sedimentation Rate (ESR)
From baseline to End of treatment = 6 weeks ± 10 days (in chronic and steroid dependent IBD patients) or 28 weeks ± 5 days (in mesalazine refractory UC patients)
Change From Baseline in Inflammatory Indexes After Receiving the Study Treatment: C-reactive Protein (CRP)
From baseline to End of treatment = 6 weeks ± 10 days (in chronic and steroid dependent IBD patients) or 28 weeks ± 5 days (in mesalazine refractory UC patients)

Treatment Arms
ArmTypeDescription
Dex 21-PEXPERIMENTALIn this arm a dose of 20 ml of Dex 2-P solution was administered every 15 or 30 days for a total of 3 or 6 treatment procedures, respectively. Specifically, steroid-dependant IBD patients had to undergo a total of 6 procedures at one month interval, while active mesalazine refractory UC patients had to undergo a total of 3 procedures at 15 days interval. Every procedure implies the collection and re-infusion of autologous erythrocytes previously loaded with Dex 21-P.
PlaceboPLACEBO_COMPARATORIn this arm placebo solution was administered every 15 or 30 days for a total of 3 or 6 treatment procedures, respectively. Specifically, steroid-dependant IBD patients had to undergo a total of 6 procedures at one month interval, while active mesalazine refractory UC patients had to undergo a total of 3 procedures at 15 days interval. Every procedure implies the collection and re-infusion of autologous erythrocytes previously NOT loaded with Dex21-P.
Interventions
NameTypeDescription
Dex 21-PDRUGAt each procedure 50 ml of patient whole blood was washed with saline solution and centrifugated. The isolated erythrocytes were suspended into 2 hypotonic solutions to make their membrane permeable and incubated with Dex 21-P sodium salt up to obtain a final concentration of 10 mM. The drug loaded erythrocytes were immediately re-infused by using a suitable filter.
PlaceboDRUGPatients assigned to placebo arm performed the same procedure as the patients assigned to the DEX 21-P group without loading in the Red Blood Cells the Dex 21-P
