•1)Male and female over 18 years old (18 years inclusive);
•2)Having a 25(OH)D3 = 20 ng/mL at the screening visit;
•3)Having intact iPTH level = 85 pg/mL and < 500 pg/mL at the screening visit;
•4)Having a stable chronic kidney disease stage 3 (estimated eGFR:30-59 mL/min/1.73 m2) at the screening visit;
•5)BMI between 18 and 30 kg/m² inclusive;
•6)Able to comply with all study procedures;
•7)Provide written informed consent to participate in the study, indicated by a personal signature and date on the patient consent form;

•Are the trial subjects under 18? no
•Number of subjects for this age range:
•F.1.2 Adults (18-64 years) yes
•F.1.2.1 Number of subjects for this age range 75
•F.1.3 Elderly (>=65 years) yes
•F.1.3.1 Number of subjects for this age range 25

•Patients who meet any of the following criteria will be excluded from participating in the study:
•1)Evidence of any unstable or untreated clinically significant immunological, renal, neoplastic, endocrine, haematological, hepatic, gastrointestinal, neurological or psychiatric abnormalities or medical disease;
•2)Acute impairment of renal function, nephritic proteinuria, malignancies and derangement of mineral metabolism of non-renal origin;
•3)Currently on dialysis;
•4)History of parathyroidectomy or renal transplantation;
•5)Serum calcium corrected by albumin > 2.65 mmol/L (corresponding to 10.6 mg/dl) at screening;
•6)Serum phosphorus > 6.0 mg/dl;
•7)History of intestinal malabsorption or chronic diarrhea;
•8)Use of any vitamin D supplementation alone or in association within 4 weeks before the screening visit;
•9)Use of any prohibited medication as detailed in the concomitant medication section;
•10)UV light solarium use 2 weeks before the screening visit and during the study;
•11)History of drug and/or alcohol abuse;
•12)Patients with any sensitivity or allergy to any of the products used within this clinical trial;
