Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 45 years
- All sexes
- No healthy volunteers
- Adult
Who may be able to join
- Study participants of reproductive potential must agree to utilize two reliable and acceptable methods of contraception simultaneously when sexually active. One of these methods must include a barrier method.
- Subjects who are not of reproductive potential include: vasectomized males or non-vasectomized males with documented azospermia prior to screening, as well as females who are surgically sterilized with bilateral tubal ligation or who have undergone hysterectomy. Women who are menopausal are also considered not of reproductive potential if there has been no menses > 12 months prior to screening and supported by a pre-screening follicle stimulating hormone (FSH) > 40 mIU/ml if available.
- Examples of reliable and acceptable methods of birth control include, but are not limited to: diaphragm with spermicide, condoms with spermicide or oral contraception with condom use in the male partner. This applies from the signing of the informed consent up until 12 weeks after the last dose of the study medication.
- Male/female subject diagnosed with chronic Chagas' disease: Previous diagnosis of acute or chronic Chagas' disease by a health clinic prior to screening for the study. The diagnosis of chronic Chagas' disease may be made by clinical findings, supported by antibody titers if available. If there is a known history of acute disease, it is preferable to have documentation of parasites on the blood smear if available
- Age: 18 to 45 years (inclusive) at the first screening visit
- Body mass index (BMI): above/equal 18 and below/equal 29.9 kg / m²
Who cannot join
- Incompletely cured pre-existing diseases (except chronic Chagas) for which it can be assumed that the absorption, distribution, metabolism, elimination and effects of the study drugs will not be normal
- Acute Chagas'disease (During the acute phase, the parasite on a blood smear may be seen under a microscope. Different antibodies are present, depending on the course of the disease)
- Known hypersensitivity to the study drugs (active substances or excipients of the preparations)
- Unstable or uncontrolled medical condition such as hypertension or diabetes, decompensated heart failure, gastrointestinal (GI) conditions that would interfere with the absorption of the study drug (e.g. GI ulceration, peptic ulceration, GI bleeding, gastroesophageal reflux, or other GI disease affecting gastroesophageal junction), conditions that could potentially have an impact on drug metabolism or elimination (renal, hepatic such as known hepatic or biliary abnormalities), or any clinically relevant active infections in the opinion of the investigator within 4 weeks before the screening visit, e.g. clinically relevant history or presence of significant respiratory (e.g. interstitial lung disease), hematological, lymphatic, neurological, cardiovascular, psychiatric, musculoskeletal, genitourinary, immunological, metabolic (e.g. diabetes), and dermatological or connective tissue disease
- Use of systemic or topical medicines or substances which oppose the study objectives or which might influence them within 4 weeks before the first study drug administration, e.g. an investigational drug, any drug altering GI motility and/or gastric pH (e.g. antacids, anticholinergic, para-sympatholytics), any drug known to induce liver enzymes (e.g. dexamethasone, barbiturates, St. John's Wort [hypericum perforatum]), any drug known to inhibit liver enzymes (e.g. ketoconazole, macrolides)
- Clinically relevant findings in the ECG such as a second- or third-degree atrioventricular block, prolongation of the QRS complex over 120 msec or of the QT-interval over 450 msec using Bazett's Formula (QTcB) or Fridericia's Formula (QTcF). (clinically stable subjects with Chagas'- related heart disease and pacemaker in place for >1 year and evaluated by a cardiologist ≤6 months before the first dose of study drug will not be excluded.)

About this study
Official title: Non-blinded, Randomized, Single Center, Single Dose, Cross-over Study to Assess the Effect of a High Calorie/High Fat Meal on the Pharmacokinetics of Four 30 mg Nifurtimox Tablets Taken Orally by Adult Male and Female Patients Suffering From Chronic Chagas' Disease
This study will evaluate the effect of food on the absorption of the drug as well as safety and tolerability of the novel 30 mg tablet (administered as 120 mg dose) in adults suffering from chronic Chagas' disease when administered after a high-fat / high-calorie test meal (American breakfast) compared to a fasting state. This study is required as part of the clinical development of an age appropriate pediatric oral dosage form for the treatment of Chagas' disease in endemic countries according to the recommendations provided by current international guidelines (EMA Guideline on Clinical Development of Medicinal Products, EMA Note for Guidance on Oral Dosage Forms).

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Nifurtimox (BAYa2502) in people with Chagas Disease, run by Bayer at 1 site in Argentina.
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 6 inclusion and 10 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 15 Nov 2016. 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 Argentina. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Area under the drug-concentration vs. time curve of nifurtimox from time 0 to the last data point[AUC(0-tlast)] (time frame: 0, 15, 30, 45 min, 1, 1.5, 2, 2.5, 4, 6, 8, 10, 12, 16, 24 hours). The study lists 4 primary outcomes in all. 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 15 Nov 2016.
