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

  • Upon consent, women of childbearing potential must use 2 forms of highly effective contraception for the duration of the study and for 12 weeks after the last drug administration. The definition of highly effective contraception will be left at the discretion of the investigator and will be in line with ICH Topic M 3 (R2): Non-Clinical Safety Studies for the Conduct of Human Clinical Trials and Marketing Authorization for Pharmaceuticals

  • 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 ar 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 gastrointestinal 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 electrocardiogram (ECG) such as a second- or third-degree AV block, prolongation of the QRS complex over 120 msec or of the QTc-interval over 450 msec
Show all 10Show fewer
  • Systolic blood pressure below 100 or above 140 mmHg (after at least 15 min supine)
  • Diastolic blood pressure below 50 or above 90 mmHg (after at least 15 min supine)
  • Heart rate below 45 or above 95 beats / min (after at least 15 min supine)

About this study

Official title: Open Label, Randomized, Single Dose Cross-over Study to Assess Bioequivalence Between Single 120 mg Nifurtimox Tablet and Four 30 mg Nifurtimox Tablets Administered Orally, Following High Calorie/High Fat Meal to Adult Male and Female Patients Suffering From Chronic Chagas' Disease and to Determine the Pharmacokinetics of Nifurtimox Tablets Administered Orally, in a Form of Aqueous Slurry

This study will evaluate the bioequivalence as well as safety and tolerability of a novel 30 mg tablet of nifurtimox compared to the corresponding marketed 120 mg tablet in adult subjects suffering from chronic Chagas' disease when administered after a high-fat / high-calorie test meal. This study is a necessary step for the 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).

  2. Maximum drug concentration of nifurtimox in plasma (Cmax)

    Measured: Up to 24 hours

Secondary outcomes (1)
  1. Number of participants with adverse events as a measure of safety and tolerability

    Measured: Up to 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Nifurtimox (BAYa2502) (4 x 30 mg tablet), Nifurtimox (BAYa2502) (slurry of 4 x 30 mg tablets in tap water) and Nifurtimox (BAYa2502) (120 mg tablet) 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 5 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 16 Oct 2015. 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-tn)] (time frame: 0-24 hours). 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?
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 Oct 2015.
