          Information to be collected by the Registry

Impavido (miltefosine) is approved in the United States to treat certain types of leishmaniasis.


For patients who weigh 99 lbs or more, Impavido is administered at a dose of three (3) of the 50-mg capsules per day for 28 days.


Patients who weight close to 99 lbs will receive more drug per pound than patients who have higher weights. For example, a patient who weighs 120 pounds will receive 1.25 mg of Impavido per pound each day [150 mg each day / 120 pounds = 1.25 mg per pound each day] whereas a patient who weighs 175 pounds will receive 0.86 mg of Impavido per pound each day [150 mg each day / 175 pounds = 0.86 mg per pound each day]. It is possible that Impavido will be less effective in higher-weight patients who receive less drug per pound than in lower-weight patients who receive more drug per pound.



The U.S. Food and Drug Administration (FDA) has FDA has required that a registry be established for Higher Weight Patients.  The Registry is used to learn more information about the efficacy and the tolerance of Impavido for higher-weight patients. The Registry will be operational between March 2015 and March 2020.


Participation in the Registry is voluntary for the patient. Lack of enrollment in the Registry will not influence or interfere with the treatment plan recommended by the patient's health care provider. Impavido is not provided by the Registry.
