Single-centre, randomized, double-blind, two-period, two-sequence, cross-over 7-day study. This study is the first safety/tolerability evaluation of a product -suppository formulation containing 6 mg BDP (once daily dosing), a second-generation oral or rectal corticosteroids with high topical anti-inflammatory efficacy in the gut and minimal systemic bioavailability (BA). BDP is marketed in different pharmaceutical formulations, including 3 mg suppositories, and approved for ulcerative proctosigmoiditis in the first attack or exacerbation phase at the dosage of 3 mg twice a day. For these reasons, a 6 mg suppository (Test - "T" product) is a scale-up of the 3 mg formulation (Reference - "R" product). For locally-applied-locally acting drug products that result in quantifiable systemic availability due to absorption from the administration site, relative systemic BA is informative for safety, but also with respect to efficacy. Therefore, safety/tolerability of T is evaluated through a comparison to R.

Other | Safety - Adverse Events | Adverse events reporting | From screening to follow up (approximately 59 days) | |
Other | Safety - Laboratory values | Incidence of abnormal laboratory test results (Urinalysis, biochemical and haematological tests performed) | At screening, before each period and at follow-up (+21 days after the end of Period 2) | |
Primary | Pharmacokinetics - Cmax, morning; | Peak exposure after the morning dose (Cmax, morning) | Day 1 and Day 7 of each Period | |
Primary | Pharmacokinetics - Cmax, evening; | Peak exposure after the evening dose (Cmax, evening) | Day 1 and Day 7 of each Period | |
Primary | Pharmacokinetics - AUC0-24 | • Total exposure over 24 hours (AUC0-24) | Day 1 and Day 7 of each Period | |
Primary | Pharmacokinetics - AUC0-12 | • Total exposure during dosing interval - morning (AUC0-12) | Day 1 and Day 7 of each Period | |
Primary | Pharmacokinetics - AUC12-24 | • Total exposure during dosing interval - evening (AUC12-24) | Day 1 and Day 7 of each Period | |
Primary | HPA-axis: 24-hour plasma cortisol - AUC0-24, cortisol | Area under the cortisol level-time curve over 24 hours (AUC0-24, cortisol). AUC will be determined for each subject/treatment at baseline and at Day 7 by the linear trapezoidal rule and ln-transformed. Ln(AUCs) will be used to determine intra-subject difference Day 7 - baseline that will be subject to analysis. |
Baseline and Day 7 of each Period | |
Primary | HPA-axis: 24-hour plasma cortisol - AUC0-12, cortisol | Area under the cortisol level-time curve over 12 hours after the morning dose (AUC0-12, cortisol). As above. |
Baseline and Day 7 of each Period | |
Primary | HPA-axis: 24-hour plasma cortisol - AUC12-24, cortisol | Area under the cortisol level-time curve over 12 hours after the evening dose (AUC12-24, cortisol). As above. |
Baseline and Day 7 of each Period | |
Primary | HPA-axis: 24-hour plasma cortisol - pAUC2-8, cortisol | Partial area under the cortisol level-time curve "covering" 3rd, 4th, 5th, 6th, 7th and 8th hour post morning dose (i.e., between 10:00 and 16:00 hours, that is, between sampling times at 2 and 8 hours post-dose) - a time period during which normal cortisol levels are still relatively high and the strongest suppression after morning dose could be expected (pAUC2-8, cortisol). As above. |
Baseline and Day 7 of each Period | |
Secondary | Pharmacokinetics - trough concentrations | Trough concentrations for R (C12) and T (C24) dosing on Day 1 and Day 7 as well as morning pre-dose (C0) | Day 1 and Day 7 of each Period | |
Secondary | Pharmacokinetics - Cmax morning/AUC0-12 ratio | Ratio of the peak exposure after the morning dose to exposure over the subsequent 12 hours (illustrates absorption rate) (Cmax,morning/AUC0-12) | Day 1 and Day 7 of each Period | |
Secondary | Pharmacokinetics - Tmax, morning | Time to peak exposure after the morning dose (Tmax,morning) | Day 1 and Day 7 of each Period | |
Secondary | Pharmacokinetics - Percent fluctuation (%PTF12) | Day 7 - percent fluctuation over 12 hours after morning dose (%PTF12) | Day 7 of each Period | |
Secondary | Pharmacokinetics - Percent fluctuation (%PTF24) | Day 7 - percent fluctuation over 24 hours (%PTF24) | Day 7 of each Period | |
Secondary | Pharmacokinetics - Accumulation ratio | Accumulation ratio (Cmax,morning Day 7/Day 1; AUC0-24 Day 7/Day 1). Accumulation ratio will be estimated based on two outcomes: peak exposure after the morning dose (Cmax, morning) and total exposure over 24 hours (AUC0-24). | Day 1 and Day 7 of each Period | |
Secondary | HPA axis - Number (proportion) of subjects with cortisol <10 µg/dL | ACTH stimulation test results on the morning of Day 9 (first post-dosing day) dichotomized as "normal" or "abnormal" | Day 8 and 9 of each Period | |
Secondary | HPA axis - Number/proportion of subjects with abnormal ACTH stimulation test. | Number (proportion) of subjects with cortisol levels <10 µg/dL at 08:00 a.m. on Day 8 and number (proportion) of subjects with abnormal ACTH stimulation test results in the morning of Day 9 (should any subject be submitted). | Day 8 and 9 of each Period | |
Secondary | HPA axis - 24-hour cortisol profile | 24-hour cortisol profile: time-point-by-time-point differences Day 7 vs. baseline | Baseline and Day 7 of each Period |
