Summary: Only a small fraction of patients with Chagas disease are properly diagnosed and treated. Currently, there is no test for the early assessment of treatment efficacy. Development of a test to determine in a timely manner whether a patient with Chagas disease has successfully responded to treatment has been identified as a priority. The authors present a target product profile (TPP) specifically describing the technical and performance characteristics required. Two use scenarios are considered: day-to-day healthcare provision, and clinical evaluation of new anti-T. cruzi drugs or alternative regimens of currently available drugs. The TPP described in this article can guide the development and uptake of these tests, which will be fundamental both to managing patients and evaluating new drugs or regimens.
