Summary: Since 2010, a combination of sodium stibogluconate (SSG) and paromomycin (PM) has been the standard of care for visceral leishmaniasis in Africa – an improvement on previous therapies but still requiring painful twice-daily injections for 17 days and risking potential toxicities associated with SSG. This open-label, phase 3, randomized, controlled trial was conducted in adult and paediatric patients in Ethiopia, Kenya, Sudan, and Uganda to determine whether paromomycin plus miltefosine (PM/MF) is noninferior to SSG/PM for the treatment of primary visceral leishmaniasis in eastern Africa. Patients received either 20 mg/kg PM plus allometric dose of MF for 14 days, or 20 mg/kg SSG plus 15 mg/kg PM for 17 days. The study showed that a PM/MF combination achieved similar cure rates at six months follow-up as the standard of care SSG/PM in adult and paediatric patients with VL in Eastern Africa (91.2% and 91.8%, respectively). PM/MF also reduced the risk of subsequent post-kala azar dermal leishmaniasis (PKDL): 20.9% of those treated with SSG/PM went on to develop PKDL versus 4.4% of those treated with PM/MF in Ethiopia and Sudan.
