An interventional study of L. casei DG® (Lactobacillus paracasei CNCM I-1572) and placebo in Vitamin D Deficiency, sponsored by SOFAR S.p.A.. Status unknown at 1 site in United Arab Emirates. Open to participants aged 18 Years to 60 Years. Per ClinicalTrials.gov, last updated 2023-04-12.

Vitamin D deficiency is one of the most underdiagnosed and undertreated medical condition worldwide . The microbiome and vitamin D deeply influence each other and the immune system in many different ways. It is evident that the immune system and the microbiome are interconnected, and that vitamin D is a critical intermediary player in this dynamic .
Probiotics were shown to increase vitamin D intestinal absorption and increase vitamin D receptor protein expression and transcriptional activity . Likewise, vitamin D receptor status seems to be crucial in regulating the mechanisms of action of probiotics and modulating their anti-inflammatory, immunomodulatory and anti-infective benefits, suggesting a two-sided pathway . The objective of this study is to assess the different absorption of Vitamin D (Vit. D) between patients treated with Vit. D supplementation combined to a probiotic containing L. casei DG® and patients treated with Vitamin D supplementation and placebo
The present study is a monocentric, exploratory, randomized, double-blind, controlled study to evaluate the effects of daily intake of L. Casei DG® (L. Paracasei CNCM I1572) on vitamin D absorption in adult patients with Vitamin D (Vit. D) deficiency, defined as a blood level of 25(OH) D ≤ 20 ng/ml.
The investigational product is ENTEROLACTIS®, a food supplement resulting from SOFAR research (listed in the Food Supplement Registry of the United Arab Emirates Ministry of Health \& Prevention with the code #12235-13911-2) available as drinkable vials of 10 ml, containing 8 billion of live cells of L. casei DG The comparator product is an identical drinkable vial of placebo. Vit. D will be provided by the sponsor as oral drops of 10. 000 U.I./mL 16 drops of Vit. D must be dissolved in the Investigational Product/placebo vial and then this has to be reconstituted and drunk immediately.
The patients will be involved in 10 on site visits: V-1 (Screening)- within 7 days before baseline visit, V0 (Baseline) at the start of therapy, V1- 1 week after the start of therapy, 6 visits (V2-V7) every two weeks and V8- follow up visit, 4 weeks after the end of treatment (EOT-V7).
Investigational Product/comparator treatment will start at V0 and will end at V7, for a duration of 12 weeks. After the End of Treatment visit (EOT-V7), patients will enter in a 4 weeks Follow Up (FU) period, for a total duration of the study of 16 weeks (12 weeks of treatment + 4 weeks of FUP). If a patient reaches normal levels of Vitamin D before EOT visit, study treatment will be interrupted, and patient will enter the FU period.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Start is estimated for Jun 2023; primary completion for Jun 2024, 12 months later.
Of 170 interventional studies with no phase under Vitamin D Deficiency, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 29. This study's planned 12 months is close to that.
