About this study

Busulfan (Bu) has been widely used for the treatment of neoplastic and non-neoplastic hematological disturbances, with satisfactory results in terms of successful hematopoietic stem cell transplantation (HSCT). Individual monitoring of the Bu dosage, which is done by means of various blood sample collections, is necessary for the purpose of attaining ideal therapeutic levels and minimizing systemic toxicity. This procedure sometimes becomes costly to and uncomfortable for the patient. Saliva has been analyzed as a possible alternative fluid for this monitoring.

Read the detailed description

The first objective of this project is to verify the feasibility of using the analysis of salivary concentration of BU during individual adjustments of this drug in the period that precedes HSCT. Another question related to this project is with reference to the effects that the Bu concentration in saliva has on the mucosa of the digestive tract, particularly with regard to mucositis and salivary changes. Thus, the second objective of this project is to verify whether there is any association between salivary changes, cytological changes in the oral mucosa, degrees of mucositis and concentration of Bu in saliva. An analysis will be performed of the Bu concentration in saliva and in blood, as well as the salivary dosage of total proteins, albumin, amylase, antioxidant enzymes (superoxide dismutase, catalase, and glutathione reductase) and pro-inflammatory cytokines IL-1β, IL-6 and TNF-α. In addition, morphological analysis will be made, and rate of apoptosis of cells of the oral mucosa will be analyzed. If the efficacy of saliva for the individual adjustment of the dose of Bu is confirmed, this method could facilitate the dissemination of pharmacokinetic monitoring of this drug in chemotherapy and HSCT centers. In addition, it is expected that the results of the present project will allow establishment of the toxicity indicators of BU detected by analysis of saliva and the cells of the oral mucosa, thereby allowing the early adoption of preventive actions for reducing the frequency and severity of mucositis, a fact that may have a positive impact on the success of HSCT.

Questions about this trial

What is this clinical trial studying?

An observational study of Bone Marrow Disease, run by Hospital Israelita Albert Einstein.

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 1 inclusion and 1 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 11 May 2021. Status can change between updates, so confirm with the study contact before making plans.

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.

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?

descriptive Analysis salivar (time frame: 2 years). 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 11 May 2021.
