Study summary

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.

  • No signed
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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 May 11, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
