Study summary

This clinical study aims to address a research and clinical treatment gap related to individuals with symptoms of Silicosis resulting from quartzite mining work. Silicosis represents a challenge in this specific population in Sao Thome das Letras, Minas Gerais. Silicosis is a severe disease and is considered incurable. Current conventional medicine only offers palliative care for those with Silicosis, highlighting the important and urgent need for research into complementary care approaches.

Read the detailed description

The study design is a simple clinical trial to assess the effect of the homeopathic medication Silica 12CH given alongside the conventional treatment of Silicosis, versus standard treatment alone for Silicosis.

The study design is a controlled non-blinded clinical study without randomization to test the effectiveness of a homeopathic intervention among individuals with symptoms of Silicosis as a result of working as quartzite miners. The intervention to be studied is a homeopathic preparation of Silica 12CH on a sample of clients with Silicosis already receiving ongoing conventional medical care. The intervention is Silica 12CH given over one year: a single dose at intervals of three months (three times in the study period).

Participants will be recruited locally through the clinic where they already receive ongoing medical attention. The local secretary of health authorizes the release of the patient files. Potential participants will be given printed information about the study details along with information about how to participate and the associated deadlines for joining the study. Interested individuals will be given the informed consent form.

Participants will freely elect to be in either the control or intervention group. Individuals in the control group follow the standard-care protocol without the homeopathic intervention. Individuals in the experimental group will receive the homeopathic intervention while also following the standard-care protocol. All individuals will be encouraged to continue with any concurrent conventional medical treatment for their Silicosis-related symptoms. Individuals in either group may freely leave the study at any time with no consequence. Additionally, participants may freely elect to be moved from the control group into the experimental group at the half-way point in the study.

What researchers measure

Primary outcomes

  1. Changes in pulmonary health of individuals with Silicosis as assessed by symptoms '1' and '2' using the Measure Yourself Concerns and Wellbeing (MYCaW validated) wellness measurement instrument. 0 = As good as it can be. 6 = As bad as it can be

    Monitor changes using validated wellness measurement instrument

    Time frame: One year

Secondary outcomes

  1. Changes in pulmonary health of individuals with Silicosis as assessed by overall wellness scores using the Measure Yourself Concerns and Wellbeing (MYCaW validated) wellness measurement instrument. 0 = As good as it can be. 6 = As bad as it can be.

    Monitor changes using validated wellness measurement instrument

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 28, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
