In-hospital safety in field conditions of nifurtimox eflornithine combination therapy (NECT) for T. b. gambiense sleeping sickness.
    PLoS neglected tropical diseases, 2012, Volume: 6, Issue:11

    Trypanosoma brucei (T.b.) gambiense Human African trypanosomiasis (HAT; sleeping sickness) is a fatal disease. Until 2009, available treatments for 2(nd) stage HAT were complicated to use, expensive (eflornithine monotherapy), or toxic, and insufficiently effective in certain areas (melarsoprol). Recently, nifurtimox-eflornithine combination therapy (NECT) demonstrated good safety and efficacy in a randomised controlled trial (RCT) and was added to the World Health Organisation (WHO) essential medicines list (EML). Documentation of its safety profile in field conditions will support its wider use.. In a multicentre, open label, single arm, phase IIIb study of the use of NECT for 2(nd) stage T.b. gambiense HAT, all patients admitted to the trial centres who fulfilled inclusion criteria were treated with NECT. The primary outcome was the proportion of patients discharged alive from hospital. Safety was further assessed based on treatment emergent adverse events (AEs) occurring during hospitalisation.. 629 patients were treated in six HAT treatment facilities in the Democratic Republic of the Congo (DRC), including 100 children under 12, 14 pregnant and 33 breastfeeding women. The proportion of patients discharged alive after treatment completion was 98.4% (619/629; 95%CI [97.1%; 99.1%]). Of the 10 patients who died during hospitalisation, 8 presented in a bad or very bad health condition at baseline; one death was assessed as unlikely related to treatment. No major or unexpected safety concerns arose in any patient group. Most common AEs were gastro-intestinal (61%), general (46%), nervous system (mostly central; 34%) and metabolic disorders (26%). The overall safety profile was similar to previously published findings.. In field conditions and in a wider population, including children, NECT displayed a similar tolerability profile to that described in more stringent clinical trial conditions. The in-hospital safety was comparable to published results, and long term efficacy will be confirmed after 24 months follow-up.. The trial is registered at ClinicalTrials.gov, number NCT00906880.

Characteristics and Adverse Events of Patients for Whom Nifurtimox Was Released Through CDC-Sponsored Investigational New Drug Program for Treatment of Chagas Disease - United States, 2001-2021.
    MMWR. Morbidity and mortality weekly report, 2022, 03-11, Volume: 71, Issue:10

    Chagas disease, or American trypanosomiasis, is caused by the parasite Trypanosoma cruzi. Chagas disease is endemic in rural areas of Latin America, but T. cruzi, triatomine vectors, infected mammalian reservoir hosts, and rare cases of autochthonous vector borne transmission have been reported in the United States (1). Possible modes of transmission include the following: vector borne via skin or mucosal contact with feces of infected triatomine bugs, congenital, blood transfusion, organ transplantation, or laboratory accident. Chagas disease can be treated with benznidazole (commercially available since May 14, 2018) or nifurtimox (2). Before January 25, 2021, nifurtimox (Lampit) had been exclusively available through CDC under an Institutional Review Board-approved Investigational New Drug (IND) treatment protocol, at which time it became reasonably accessible to health care providers outside of the program. This report summarizes CDC Drug Service reports for selected characteristics of and adverse events reported by 336 patients for whom nifurtimox was requested under the CDC IND program during January 1, 2001-January 25, 2021. Of the 336 patients, 34.2% resided in California. Median age of patients was 37 years (range = 1-78 years). Most patients were aged ≥18 (91.8%; 305 of 332) and Hispanic (93.2%; 290 of 311). Among the patients with available information, 91.4% (222 of 243) reported an adverse event. Among those with information about the severity of their adverse events, 20.5% reported a severe event. On August 7, 2020, the Food and Drug Administration (FDA) announced approval of a nifurtimox product, Lampit (Bayer), for treatment of Chagas disease in patients aged <18 years weighing ≥5.5 lbs (≥2.5 kg). Lampit became commercially available during October 2020. Physicians should take frequency of adverse events into consideration when prescribing nifurtimox and counseling patients.

Toxicity of nifurtimox as second-line treatment after benznidazole intolerance in patients with chronic Chagas disease: when available options fail.
    Clinical microbiology and infection : the official publication of the European Society of Clinical Microbiology and Infectious Diseases, 2018, Volume: 24, Issue:12

    To describe the tolerability and rate of nifurtimox discontinuation when administered as a second-line treatment to patients with previous treatment interruptions due to adverse reactions with benznidazole.. We studied a prospective cohort study of adult patients with chronic Chagas disease in a referral centre in Spain treated from July 2007 to July 2017. We analysed the tolerability profile and treatment interruption rate due to adverse reactions (ARs) to nifurtimox in patients previously incompletely treated (less than 30 days) with benznidazole due to ARs.. A total of 472 patients initiated treatment with benznidazole during the study period. Of these, 118 (25%) developed ARs that led to treatment discontinuation before 30 days of therapy. Fifty-three (44.9%) of 118 initiated nifurtimox as second-line treatment; most were women (79.3%), were of Bolivian origin (98.1%) and had a median age of 37.3 years (interquartile range, 29.8-43.2). The most common ARs with nifurtimox were cutaneous hypersensitivity (24.1%), digestive disorders (22.2%), fever (12.9%), neurologic disturbances (11.1%), depression, anxiety or insomnia (9.2%), dyspnoea (7.4%), myalgia (5.5%), and dizziness, asthenia or malaise (7.4%). Twenty-six (49.1%) of 53 patients discontinued nifurtimox due to ARs, all of them before the required minimal therapy duration of 60 days. There were no deaths.. Treatment of chronic Chagas disease relies on two drugs with a poor tolerability profile. In our cohort, 12.3% of the patients who initiated benznidazole and subsequently nifurtimox in case of nontolerance developed ARs that led to permanent treatment discontinuation. Most were women of childbearing age, a group for whom therapy has the added benefit of interrupting vertical transmission.

Safety Profile of Nifurtimox for Treatment of Chagas Disease in the United States.
    Clinical infectious diseases : an official publication of the Infectious Diseases Society of America, 2016, 10-15, Volume: 63, Issue:8

    Nifurtimox is 1 of only 2 medications available for treating Chagas disease (CD) and currently the only drug available in the United States, but its safety and tolerance have not been extensively studied. This is the first study to evaluate tolerance of nifurtimox in US patients with CD.. This investigation assessed side effects in a sample of 53 patients with CD, all Latin American immigrants, who underwent treatment with nifurtimox (8-10 mg/kg in 3 daily doses for 12 weeks) from March 2008 to July 2012. The frequency and severity of adverse events (AEs) was recorded.. A total of 435 AEs were recorded; 93.8% were mild, 3.0% moderate, and 3.2% severe. Patients experienced a mean of 8.2 AEs; the most frequent were anorexia (79.2%), nausea (75.5%), headache (60.4%), amnesia (58.5%), and >5% weight loss (52.8%). Eleven patients (20.8%) were unable to complete treatment. Experiencing a moderate or severe AE (odds ratio [OR], 3.82; P < .05) and Mexican nationality (OR, 2.29; P < .05) were significant predictors of treatment discontinuation, but sex and cardiac progression at baseline were not. Patients who did not complete treatment experienced nearly 3 times more AEs per 30-day period (P = .05).. Nifurtimox produces frequent side effects, but the majority are mild and can be managed with dose reduction and/or temporary suspension of medication. The high frequency of gastrointestinal symptoms and weight loss mirrors results from prior investigations. Special attention should be paid during the early stages of treatment to potentially severe symptoms including depression, rash, and anxiety.
