Exclusion criteria
Exclusion criteria: 1. Clinically significant abnormalities on 12-lead (supine position) electrocardiogram (ECG) 2. Clinically significant abnormal physical findings which could interfere with the objectives of the study 3. Clinically significant abnormal laboratory values indicative of physical illness, especially hypercalcemia and hypercalciuria 4. Ascertained or presumptive hypersensitivity to the active principle and/or formulations' ingredients, history of anaphylaxis to drugs, or history of allergic reactions in general which the investigator considers may affect the outcome of the study 5. Significant history of renal, hepatic, gastrointestinal, cardiovascular, respiratory, skin, haematological, endocrine, or neurological diseases that may interfere with the aim of the study, especially sarcoidosis, kidney failure, nephrolithiasis, nephrocalcinosis, or liver failure 6.

|---|---|
| 1. Bioavailability of vitamin D3 after a single oral dose of Test (T) or marketed reference (R), under fed conditions, measured as maximum serum concentration (Cmax) and area under the plasma drug concentration-time curve (AUC0-t) of for plasma calcifediol (25(OH)D3) using a fully validated Liquid Chromatography with tandem mass spectrometry (LC-MS-MS) method, with a lower quantification limit of 1 ng/ml, on blood samples taken at -12, -1, and 0 h, 15 and 30 min, and 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 144, 312, 480 and 648 h | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Maximum serum concentration (Cmax) and area under the plasma drug concentration-time curve (AUC0-t) of for plasma calcifediol (25(OH)D3) after a single dose administration of T under fasting and fed conditions measured using a fully validated Liquid Chromatography with tandem mass spectrometry (LC-MS-MS) method, with a lower quantification limit of 1 ng/ml, on blood samples taken at -12, -1, and 0 h, 15 and 30 min, and 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 144, 312, 480 and 648 h 2. Pharmacokinetic (PK) profile of 25(OH)D3 after a single dose administration of T and R under fed conditions measured using a fully validated Liquid Chromatography with tandem mass spectrometry (LC-MS-MS) method, with a lower quantification limit of 1 ng/ml, on blood samples taken at -12, -1, and 0 h, 15 and 30 min, and 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 144, 312, 480 and 648 h 3. PK profile of 25(OH)D3 after a single dose administration of T under fasting conditions measured using a fully validated Liquid Chromatography with tandem mass spectrometry (LC-MS-MS) method, with a lower quantification limit of 1 ng/ml, on blood samples taken at -12, -1, and 0 h, 15 and 30 min, and 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 36, 48, 72, 144, 312, 480 and 648 h 4. Safety and tolerability of Vitamin D3 will be evaluated during the study by the number of adverse events (AEs) reported throughout the study duration and measured using: 4.1. Blood and urine samples for haematology, blood chemistry, and urine analysis at the screening visit and final visit/ETV 4.2.
