About this study

Official title: Relevance of Monitoring Blood Levels Compared to Salivar Levels of Drugs Used in Rheumatic Autoimmune Diseases: Adherence and Understanding the Possible Underlying Mechanisms Involved in Effectiveness and in Adverse Effects

No drug treatment is completely free of risk and lack of response, adverse events and poor adherence may affect its effectiveness. Within this context, this project aims to evaluate the importance of monitoring blood levels and salivary drug used in rheumatic autoimmune diseases in the monitoring of adherence to therapy. In addition, this project intends to use the monitoring of drug levels, based on pharmacokinetic studies and pharmacokinetics/pharmacodynamics modeling, to broaden the understanding of the possible cellular, tissue and immunological mechanisms involved in efficacy and adverse effects of these drugs with the prospect of reducing the damage and maintain therapeutic efficacy. The high-performance liquid chromatography (HPLC) coupled to mass spectrometry, which will be used to evaluate hydroxychloroquine, thalidomide, glucocorticoids, is considered the gold standard technology to qualitative and quantitative analysis of drugs in blood and its comparison with the dosage in the saliva is an improvement in simplification of the process. For biological agents the focus will be on the understanding the loss of efficacy and the possible role of anti-TNF antibodies using ELISA capture methodology.This project will be divided into four sections with their respective sub-projects according to the medications that will be studied: hydroxychloroquine, thalidomide, biologic agents and glucocorticoids.

Read the detailed description

No drug treatment is completely free of risk and lack of response, adverse events and poor adherence may affect its effectiveness. There is also a large inter-individual variability in response to treatments with regard to efficacy and toxicity, and for many drugs, there is also a period of weeks to months to establish its efficacy. Within this context, this project aims to evaluate the importance of monitoring blood levels and salivary drug used in rheumatic autoimmune diseases in the monitoring of adherence to therapy. In addition, this project intends to use the monitoring of drug levels, based on pharmacokinetic studies and pharmacokinetics/pharmacodynamics modeling, to broaden the understanding of the possible cellular, tissue and immunological mechanisms involved in efficacy and adverse effects of these drugs with the prospect of reducing the damage and maintain therapeutic efficacy. The high-performance liquid chromatography (HPLC) coupled to mass spectrometry, which will be used to evaluate hydroxychloroquine, thalidomide, glucocorticoids, is considered the gold standard technology to qualitative and quantitative analysis of drugs in blood and its comparison with the dosage in the saliva is an improvement in simplification of the process. The implementation of this methodology dedicated to research in our center, with the necessary training of human resources, will enable the standardization and availability of this advanced technology to other muldisciplinary projects in various areas of science. For biological agents the focus will be on the understanding the loss of efficacy and the possible role of anti-TNF antibodies using ELISA capture methodology.This thematic project will be divided into four sections with their respective sub-projects according to the medications that will be studied: hydroxychloroquine, thalidomide, biologic agents and glucocorticoids.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Thalidomide, Hydroxychloroquine reduced and standard dose of HCQ in people with Systemic Lupus Erythematosus (SLE) and Juvenile SLE, run by University of Sao Paulo General Hospital at 1 site in Brazil.

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 10 inclusion and 18 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 16 Dec 2021. 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 Brazil. 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?

Yes. Results are posted in the registry (first posted 16 Dec 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Serum Levels of Thalidomide (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03122431, which also lists 20 linked publications.

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 16 Dec 2021; AzTrials last refreshed its copy on 8 Nov 2026.
