An IVR application was developed with scripting in English, Zulu, Afrikaans, and Xhosa. Patients were enrolled by the sites, and needed to first qualify into the study, both by symptoms and compliance with the IVR. After the placebo phase, the IVR system assigned the study drug to the patient, and monitoring continued though the study phase. Data was collected from the patients, who called into the platform two times daily. |
