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

  • Written informed consent must be provided before any study-specific tests or procedures are performed.
  • Male/female patient 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.
  • Women and men of reproductive potential must agree to use adequate contraception when sexually active. This applies for the time period between signing of the informed consent form and 12 weeks after the last administration of study drug. The definition of adequate contraception will be based on the judgment of the investigator and on local requirements. Acceptable methods of contraception include, but are not limited to: (i) condoms (male or female) with or without a spermicidal agent; (ii) diaphragm or cervical cap with spermicide; (iii) intra-uterine device; (iv) hormone-based contraception. Subjects must agree to utilize two reliable and acceptable methods of contraception simultaneously.
  • Women of childbearing potential with confirmed last menstrual period by anamnesis and negative serum pregnancy test (beta-human chorionic gonadotropin [βhCG]) at screening and negative urine pregnancy test (βhCG) at pre-dose of each treatment.
  • Women of non-childbearing potential, such as surgically sterile women with either written documentation of surgical sterility or negative serum pregnancy test (βhCG) at screening and negative urine pregnancy test (βhCG) at pre-dose of each treatment.

  • Male subjects who agree not to act as sperm donors for 12 weeks after last administration of study drug.
  • Age: 18 to 45 years (inclusive) at screening.
  • Body mass index (BMI): ≥18 and <29.9 kg/m².

Who cannot join

  • Incompletely cured pre-existing diseases (except chronic Chagas' disease without active GI condition) 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 drug (active substance or excipients of the preparations)
  • Unstable or uncontrolled medical condition such as hypertension or diabetes, decompensated heart failure, 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 (including clinical treatment with nifurtimox and benznidazole) 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). (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.)
  • Systolic blood pressure <100 or >140 mmHg (after resting in supine position for a minimum of 3 minutes).
  • Diastolic blood pressure <50 or >90 mmHg (after resting in supine position for a minimum of 3 minutes).

About this study

Official title: Open-label, Randomized, Single-dose, Cross-over Study to Evaluate the Influence of Dietary Habits on the Pharmacokinetics, Safety, and Tolerability of a 120 mg Dose and to Assess the Relative Bioavailability of a 240 mg Dose of Nifurtimox Tablets Administered to Adult Male and Female Patients With Chagas' Disease

This study evaluated the effect of food on the absorption of the drug as well as safety and tolerability in adults suffering from chronic Chagas' disease In addition pharmacokinetics of the drug following 120 and 240 mg single doses will be assessed

Read the detailed description

Primary objective was to evaluate the effect of various food compositions on the PK of nifurtimox after a single oral dose (120 mg) administered under 3 types of fed conditions (low fat, dairy products, and high calorie and high fat), as well as fasted conditions, to assess relative bioavailability. It was chosen to allow a direct inter-study comparison of PK data obtained in previous studies.

A secondary objective of the study was to assess the relative bioavailability of 2 different dose levels of nifurtimox, given as a single oral dose, in a second group of patients.The second treatment group addressed a biopharmaceutical aspect for which no study data have been obtained to date. In order to assess the relationship between dose and exposure (linearity of PK), an analysis of the dose range of 120 mg to 240 mg was chosen to close the knowledge gap for this dose range.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Nifurtimox (Lampit, 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 9 inclusion and 8 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 30 Dec 2020. 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?

AUC(0-tlast) of nifurtimox (evaluation of food effect) (time frame: 0, 15, 30, 45 min, 1, 1.5, 2, 2.5, 3, 4, 6, 8,12,15 hour). 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?

On the ClinicalTrials.gov record for NCT03334838, which also lists 1 linked publication.

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 30 Dec 2020.
