Plain English Summary

Background and study aims
Vitamin D3 is very important for health because strengthens the bones, helps prevent autoimmune diseases, regulates neuromuscular function and helps fight the symptoms of depression. The new orodispersible formulation developed by IBSA for the present study dissolves and/or disintegrates rapidly when placed in the mouth without drinking or chewing, providing a valuable alternative to the already marketed drug products for vitamin D supplementation.

The main aim of this study is to compare the amount of the active substance of a new vitamin D3 formulation that reaches the blood flow compared to a reference formulation in healthy subjects.

Who can participate?
Healthy people aged 40-70 years old, were able to participate. Participants had to comprehend the full nature and purpose of the study, including possible risks and side effects and co-operate with the investigator to comply with the requirements of the entire study. Women of childbearing potential were required to use at least one reliable method of contraception.

What does the study involve?
Study participants will be randomly allocated to one of three groups to receive a single dose of the study drug (IBSA Vitamin D3 orodispersible film) by mouth or the reference drug (a liquid taken by mouth):
1. The Tfast group were administered a single dose of the study drug under fasting conditions
2. The Tfed group were administered a single dose of the study drug under fed conditions
3. The Rfed group were administered a single dose of the reference drug under fed conditions

The study drug being tested is not yet available on the market in Switzerland, and should therefore be considered a trial product whereas the reference formulation is already on the market. Participants will have blood samples taken, and vital parameters recorded at regular intervals.

In addition, a full physical examination (body weight, height, vital signs, physical abnormalities) and laboratory parameters (measured on blood and urine samples, as applicable) will be performed at the screening and final visit (or, if participants leave the trial before the final visit, at the point of participation being terminated early).

What are the possible benefits and risks of participating?
Participating in this study is not expected to bring any direct benefit to participants, with the exception of the medical tests that will be performed during the study. Vitamin D supplementation is safe. No toxicity is expected at the dose foreseen in the present study, which will be administered once to each volunteer. However, as with all products, the appearance of allergic reactions or side effects that are known or not yet known cannot be ruled out.

Where is the study run from?
The CROSS Research S.A. Phase I Unit Clinical Centre (Switzerland)

When is the study starting and how long is it expected to run for?
From May 2019 to November 2019.

Condition

Vitamin D deficiency

Intervention

The first screening visit will take place between Day -21 and Day -2. Study participants will be randomly allocated, according to a randomised parallel group design (1:1:1), to one treatment according to the randomisation list, computer-generated by the Biometry Unit of the Contract Research Organisation (CRO) and supplied to the study site before study start. This is an open label study. Subjects will be randomised on Day -1, according to their randomisation number, and will be allocated to one of the following three groups, to receive either a single dose of test (T) (IBSA Vitamin D3 25000 I.U. orodispersible film) or the reference (R) (DIBASE®, oral solution) treatments:
1. The Tfast group were administered a single dose of T under fasting conditions
2. The Tfed group were administered a single dose of T under fed conditions
3. The Rfed group were administered a single dose of R under fed conditions

Both test and reference treatments will be orally administered. Before administration, all the subjects will wet their mouth by swallowing 20 ml of still mineral water. Tfast subjects will receive the test product under prolonged fasting conditions (from 10 h pre-dose to 5 h post-dose), while Tfed and Rfed subjects will receive the IMPs 30 min after having started to eat a light breakfast. Rfed subjects will drink the contents of 1 vial of reference treatment immediately on opening. Tfast and Tfed subjects will open 1 sachet containing one orodispersible film of test treatment and its contents will be immediately placed on their tongue, allowing it to dissolve without chewing.

Participants will have blood samples taken, and vital parameters recorded at regular intervals. Blood samples will be 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. Subjects will attend 8 visits for assessment, Visit 3 will take place on one of Days 1-3, Visit 4 on Day 4, Visit 5 on Day 7, Visit 6 on Day 14, Visit 7 on Day 21, and Visit 8 on Day 28. In the case of early discontinuation, discontinued subjects will undergo an early termination visit (ETV).

Subjects are weighed (kg) lightly clothed without shoes to record body weight at screening and final visit or the early termination visit (ETV). Height is measured at screening only. Body Mass Index (BMI) is calculated as weight [kg]/(height [m] x height [m]) at screening and final visit/ETV. Vital signs (blood pressure [mmHg], heart rate [bpm]) are measured by the investigator after 5 min at rest in sitting position at screening, -1 days and final visit/ETV. A 12-Lead ECGs will be performed in the supine position at screening.

The following laboratory analysis will be performed:
1. Haematology, blood chemistry, serum virology, and urine analysis at the screening visit
2. A urine drug test and a serum pregnancy test at the screening visit and at the entrance of each study period
3. Haematology, blood chemistry, and urine analysis at the final visit/ETV

Subjects are asked about the occurrence of adverse events (AEs) from the Informed Consent (IC) signature to the study end. Additionally, any clinically significant vital sign or laboratory value is reported as AE. AEs are coded by System Organ Class (SOC) and Preferred Term (PT), using the Medical Dictionary for Regulatory Activities (MedDRA). AEs are classified as pre-treatment AEs (PTAEs) and Treatment-Emergent AEs (TEAEs), according to the period of occurrence, as follows:
1. PTAEs include all AEs occurring after IC signature by the enrolled subject but before the first dose of IMP
2. TEAEs include all AEs occurring or worsening after the administration of the first dose of IMP
