About this study

Official title: Prospective Clinical Study on Vitamin D Replacement in Bronchiectasis - A Pilot Study

This study seeks to address the limitations in previous related studies on vitamin D replacement and bronchiectasis exacerbation occurrence through a self-controlled pilot study. The investigators aim to investigate whether vitamin D replacement in bronchiectasis patients with vitamin D deficiency can reduce hospitalized bronchiectasis exacerbation occurrence. Patients who participated in the prior study entitled "Prospective clinical study on serum 25-hydroxyvitamin D (25-OH D) level and risk of bronchiectasis exacerbation" (UW 22-317) will be invited for participation during regular clinic follow-up and management in Queen Mary Hospital. If participants are willing to join the further research, participants will be recruited in this self-controlled study. There are some differences from usual management to non-CF bronchiectasis subjects. The study subjects would be checked for their blood 25-hydroxyvitamin-D level during the study period. The non-CF bronchiectasis subjects with Vitamin D deficiency would be given 1000 IU and 2000 IU (if needed). The investigators aim to correct their Vitamin D deficiency completely, aiming at blood 25-hydroxyvitamin-D level >=50, i.e. treat to target. The dose depends on the level of Vitamin D after replacement. If blood 25-hydroxyvitamin-D level is 50 or above, then 1000 IU is suffice. If blood 25-hydroxyvitamin-D level is still below 50, the investigators will increase to 2000 IU.

Study groups in NCT06551337
Study groupRoleWhat they receive
Vitamin D replacementActive comparatorThose with vitamin D deficiency will be replaced with vitamin D3 at 1000 IU at the first visit. Vitamin D3 1000 IU is expected to increase blood 25-hydroxyvitamin-D level by 25 nmol/L. Blood 25-hydroxyvitamin-D level will be rechecked 3 months after replacement. If the blood 25-hydroxyvitamin-D level is still below 50 nmol/L, the vitamin D3 replacement dosage will be increased to 2000 IU.

Vitamin D non-deficiencyNo interventionNo drug will be given to patients with Vitamin D non-deficiency.

What is being measured

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

  1. Proportion of patients who develop hospitalized bronchiectasis exacerbation

    The proportion of patients who develop hospitalized bronchiectasis exacerbation during the follow-up period of 12 months, when compared with the 1-year period before.

    Measured: From 1-year period before baseline to 12 months

Secondary outcomes (3)
  1. Change in St. George's Respiratory Questionnaire (SGRQ) score

    Scores range from 0 to 100, with higher scores indicating more limitations.

    Measured: From baseline to 6 and 12 months.

  2. Change in bronchiectasis impact measure (BIM) score

    A score ranges from 0 to 10 for each of eight domains consists of cough, sputum, breathlessness, tiredness, activity, general health, control, and exacerbation, with 10 being most severe.

    Measured: From baseline to 6 and 12 months.

  3. Change in Bronchiectasis Health Questionnaire (BHQ) score

    The instrument comprises 10 questions, each scored on a 7-point scale, to assess quality of life related to bronchiectasis on individuals for a recall period of 2 weeks. The total score ranges from 10 to 70, with a lower score indicating a more negative impact on health-related quality of life (HRQOL).

    Measured: From baseline to 6 and 12 months.

Model description
104 subjects will be separated into two groups according to their Baseline blood 25-hydroxyvitamin-D level: vitamin D deficient (below 50 nmol/L) and vitamin D non-deficient (at or above 50 nmol/L). There were initially 42 and 62 patients in the vitamin D deficient and vitamin D non-deficient groups respectively.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Vitamin D3 in people with Bronchiectasis, run by Queen Mary Hospital, Hong Kong at 1 site in Hong Kong.

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 3 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 13 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Hong Kong. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Wang Chun Kwok, MBBS (2255 3111, kwokwch@hku.hk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients who develop hospitalized bronchiectasis exacerbation (time frame: From 1-year period before baseline to 12 months). 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 13 Aug 2024.
