    SIDE EFFECTS

    The following clinically significant adverse reactions observed with ARAKODA are discussed in detail in the Warnings and Precautions section:

    • Hemolytic Anemia [see WARNINGS AND PRECAUTIONS]
    • Methemoglobinemia [see WARNINGS AND PRECAUTIONS]
    • Psychiatric Effects [see WARNINGS AND PRECAUTIONS]
    • Hypersensitivity Reactions [see WARNINGS AND PRECAUTIONS]

    Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.

    The safety of tafenoquine was studied in clinical trials at various doses and regimens in 3,184 subjects. The recommended ARAKODA regimen was evaluated in 825 subjects in 5 controlled clinical trials (Trials 1, Trial 2, Trial 3, Trial 4 and Trial 5). The mean duration of exposure to ARAKODA in these five clinical trials was 21 weeks (range 10-29 weeks). Trial 1, 2 and 4 were conducted in healthy semi-immune volunteers in Ghana or Kenya and were placebo-controlled; a mefloquine arm was included in Trials 2 and 4 as a benchmark. Trial 3, an active comparator (mefloquine) controlled trial was conducted in healthy soldiers deployed in East Timor (Timor Leste). A placebo-controlled Trial 5 was conducted in healthy volunteers in the United States and United Kingdom. The mean age of the subjects included in the five trials was 29 years (range 17 to 69 years); 84% were male.
