| New Dosage | NCT03981523 ↗ | New Therapies and Biomarkers for Chagas Infection | Active, not recruiting | Barcelona Institute for Global Health | Phase 2 | 2019-12-18 | Chagas disease (CD) is an endemic zoonotic disease with a significant global impact. Current approved treatments for CD (benznidazole (BZN) and nifurtimox (NFX)) were developed in the 1970s with regimens and dosing intervals derived from decades-old patient series and with very limited direct comparisons. Treatment recommendations vary significantly from country to country and the comparative evidence-base with the current treatment regimens is limited. The reported efficacy of both drugs in patients with T. cruzi infection is variable and depends on the disease stage, the drug dose, the age of patients, and the infecting T. cruzi strain or genotype. Due to a therapeutic failure of at least 20% after 12 months in chronic patients and the high rate of adverse events, together with the recent data that suggest that we may be overdosing patients, we propose to test new dosing regimens of these two old compounds. Hypotheses: - Lowering the frequency of drug dosing of BZN and NFX, the plasma drug levels of the drugs within the therapeutic range will be maintained. - The duration of treatment with BZN or NFX may be related to the effectiveness of these drugs. - Blood levels of the proposed biomarkers will significantly diminish or became negative after a relatively short interval after treatment. |

| NCT00699387 ↗ | Population Pharmacokinetics of Benznidazole in Children With Chagas Disease | Completed | Consejo de Investigacion en Salud Gobierno de Buenos Aires | N/A | 2007-04-01 | Background: Chagas disease is a parasitic infection caused by the Trypanosome cruzi. The initial phase of the infection happens mainly in children. Up to 10% of infected children die. Survivors often develop chronic infection leading to heart disease and other complications in 30% of patients. These complications often result in death or severe handicaps in early adulthood, depriving societies of individuals in their most productive years. There are 20 million people infected in Latin America. Complications lead to 20,000 deaths every year. Treatment during the acute phase with benznidazole leads to a high cure rate. However, there are very few studies of this drug and virtually none in children, even though benznidazole was developed over 30 years ago. Hypotheses and Specific Aims: We hypothesize that the pharmacokinetics of benznidazole in children is different from adults, and that obtaining information on how it is absorbed, distributed and eliminated in children will allow optimization of treatment of Chagas disease in this population. This will in turn improve the outlook for children by reducing mortality and long term complications. We aim to study the pharmacokinetics of benznidazole in children receiving the drug for treatment of Chagas disease, and to correlate it with treatment effectiveness and incidence of adverse effects. Potential Impact: This novel knowledge will allow better and more rational approaches to the treatment of Chagas disease. It will also set the foundation for further studies that will be able to test improved therapies that may increase treatment response in vulnerable children. |
