Clinical Trial Summary

This is an open label, Phase III, randomized, controlled, parallel arm multicentre non-inferiority clinical trial to compare the efficacy and safety of two combination regimens of Miltefosine and Paromomycin with the standard SSG-PM for the treatment of primary adult and children VL patients in Eastern Africa.


Description:

The 2 treatment regimens to be tested are: - Arm 1: Paromomycin 20 mg/kg/d IM for 14 days combined with oral miltefosine allometric dosing for 14 days - Arm 2: Paromomycin 20 mg/kg/d IM for 14 days combined with oral miltefosine allometric dosing for 28 days (recruitment in this arm was discontinued under protocol v4.0 dated 22 Jul 2019) The reference arm is the current standard treatment for VL: • Arm 3: Sodium Stibogluconate 20 mg/kg/day IM/IV combined with Paromomycin 15 mg/kg/day IM for 17 days The target population will be VL patients from 4 to 50 years old in order to cover both paediatric and adult population. Patients will be hospitalized for 14 days of PM and MF treatment for both arm 1 and arm 2. MF treatment will start at the same time as PM treatment and for arm 2 it will continue on an out-patient basis until completion of the 28 days treatment. SSG&PM combination therapy will be administered for 17 days according to routine VL treatment guidelines and patients will remain hospitalized for the entire duration of the treatment. All patients will be asked to return to the hospital for a full assessment on day 28, and for followup visits on day 56 and at six months. To respond to the objectives, study assessments will be carried out at screening and on days 1, 3, 7, 14, 21, 28, 56 (one-month post-treatment) and 210 (six-month post-treatment). These assessments will include clinical, parasitological, haematological, biochemistry, safety, pharmacokinetic and pharmacodynamics assessments.

Outcome

Type Measure Description Time frame Safety issue
Primary Definitive Cure Cure at 6 months follow up defined as absence of clinical signs and symptoms of VL at D210 and no requirement for rescue treatment during the trial (e.g. no relapse or initial treatment failure). 6 months follow-up (Day 210)
Secondary Incidence of Treatment-Emergent Adverse Events Frequency of SAEs and AEs requiring treatment discontinuation
Frequency and severity of adverse events from the start of treatment through the last visit, at day 210.
From Screening to day 210
Secondary Initial cure at day 28 Initial cure: cure at the end of treatment (Day 28), defined as recovery of clinical signs and symptoms; absence of parasites (microscopy) and no rescue treatment administered up to and including Day 28.
Probable cure: absence of clinical signs and symptoms of VL at D56 and no prior requirement for rescue medication.
Initial cure: day 28; Probable cure: day 56
Secondary Pharmacokinetics of paromomycin and miltefosine Total and partial blood plasma exposure to paromomycin and miltefosine defined as the area under the concentration-time curve During treatment, at 1 month (day 56) and 6 months (day 210) follow-up
Secondary Pharmacodynamics Blood parasite clearance over time (qualitative and quantitative), as measured by qPCR from blood samples From baseline until day 210, and at any suspicion of relapse during the trial.
Secondary Compliance to miltefosine treatment in an outpatient setting Compliance to MF treatment in an outpatient setting will be assessed through patients' hospital records history, drug accountability and PK measurements. Day 15 to day 28 miltefosine treatment
