About this study

Official title: A Multicentre, Phase-II, Randomised, Double Blind, Placebo-controlled Study to Assess the Safety and the Efficacy of a Weekly Administered Dose of 30,000 IU Vitamin D (Colecalciferol) in Deficient Patients Diagnosed With PCOS

This is a human, II/b phase, multicentre, randomised, double blind, placebo-controlled study to assess the safety and the efficacy of a weekly administered dose of 30,000 IU vitamin D (colecalciferol) in deficient patients diagnosed with PCOS.

Investigational products: 30.000 IU vitamin D or placebo administered once a week for 12-weeks-long period, followed by a 12-week-long open label treatment 30.000 IU vitamin D in a follow-up period.

Each participant should be checked for regular dietary Ca intake and to assure the optimal calcium level the supplementation is provided with a commercially available Citrocalcium 200 mg tablets.

Setting:

  1. Baseline and screening period:

Baseline period considered as when the exogenous Vitamin D intake should not exceed the level of 1000 IU intake per day or a total 5000 NE per week dosages applied (in forms of any Vitamin D3 medication or multivitamin products) at least for 30 days prior the assessment made.

II. Double-blind treatment period:

Once a week per os applied Vitamin D or placebo treatment for 12 weeks according to randomisation of trial subjects in a 1:1 assignment. By the end of this period an interim assessment will be performed based on the analysis of primary efficacy parameters, stratification to responder and non-responder groups.

III. Open label and follow-up phase:

An open-label 30000 IU of Vitamin D treatment on weekly basis. (Vitamin D3 Pharma Patent 30000 IU tablets) for additional 12 weeks and continue with the follow-up assessments. A compassionate use of patient diary for additional 26 weeks.

Objectives:

Primary objectives: to assess the efficacy as a recovery of ovarian function based on progesterone levels and menses diary in at least 20% of trial subjects, compared to placebo treated group Secondary Objectives: assess the efficacy and safety of orally administered vitamin D treatment by the changes in 25(OH) D levels in PCOS patients.

Explore the changes in Ovarian-morphology based on the results of standard TVUS Imaging: detection of adverse drug reactions during treatment periods, by frequency and distribution compared to follow-up periods and placebo group.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Recovery of ovarian function

    Recovery of ovarian function is detected by changes in progesterone levels (lutal phase progesterone level reaches 2 ng/ml)

    Measured: Up to 32 weeks, continuously

Secondary outcomes (9)
  1. Length of menstrual cycle

    Determined by patient reported number of days between two menstrual cycles

    Measured: Up to 32 weeks

  2. Variation in menstrual cycles length

    Determined by patient reported menstrual cycle length and regularity, measured in days

    Measured: Up to 32 weeks

  3. Incidence of adverse events

    Incidence of adverse events (safety and tolerability), evaluated at every visit

    Measured: Up to 32 weeks, continuously

  4. Change in serum calcium level

    Change in serum calcium levels in mmol/l (safety measure), evaluated every clinical visit

    Measured: Up to 32 weeks, continuously

  5. Change in urinary calcium/creatinine ratio

    Change in urinary calcium/creatinine ratio ([mmol/l]/[umol/l]) (safety measure), evaluated every clinical visit

    Measured: Up to 32 weeks

  6. 25(OH)D levels

    Evaluation of treatment of changes in 25(OH)D blood levels compared between treatment groups

    Measured: Up to 32 weeks

  7. Change in fasting glucose level

    Change in fasting glucose level (mmol/l), measured at every visit

    Measured: Up to 32 weeks

  8. Change in hemoglobin A1c level

    Change in hemoglobin A1c level (IFCC validated, mmol/mol), measured every 12 weeks

    Measured: Up to 32 weeks

  9. Change in ovarian morphology

    Changes in ovarian follicle count assessed by TVUS and evaluated by the Rotterdam criteria (having 12 or more follicles, measuring between 2 and 9 mm)

    Measured: Up to 32 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cholecalciferol in people with Polycystic Ovary Syndrome and Vitamin D Deficiency, run by Semmelweis University at 8 sites in Hungary.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Hungary. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recovery of ovarian function (time frame: Up to 32 weeks, continuously). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2024.
