Severe Acute Malnutrition HIV Comorbidities and Coexisting Conditions Child Malnutrition | Drug: Rifampicin Drug: Azithromycin Drug: Isoniazid Drug: Pyridoxine Hydrochloride Behavioral: The Friendship Bench Behavioral: Care for Child Development Behavioral: Educational and behaviour-change modules Dietary Supplement: Reformulated Ready to Use Therapeutic Food Other: Standard Care | Phase 3 |
This is a 5-arm randomized, unblinded clinical trial comparing:
Arm 1: Standard-of-care (control) Arm 2: Antimicrobial package Arm 3: Reformulated RUTF Arm 4: Psychosocial package Arm 5: Antimicrobial package + reformulated RUTF + psychosocial package
The trial will test the superiority of each intervention arm over the standard of care arm (control). Children in the control arm (and all intervention arms) will receive RUTF for at least 2 weeks and all standard care. The trial is adaptive, meaning i) that each intervention arm will be added as it becomes available, and ii) an interim analysis will enable us to drop arms which are unpromising based on pre-specified criteria. There will be no blinding or placebo, because the very different components in each trial arm make it very challenging to blind. Children with complicated SAM will be screened and enrolled from hospital sites shortly before discharge, and interventions will be started before leaving hospital, and continued for 12 weeks through outpatient visits. Children will be followed at 2, 4, 6, 8, 12 and 24 weeks post-discharge in dedicated study clinics (with additional visits at 1, 3 and 5 weeks for caregiver-child pairs receiving the psychosocial intervention).
The primary outcome is death or hospitalization or failed nutritional recovery by 24 weeks.
The aim is to recruit 1266 children across three countries. The study is not testing new drugs but rather testing a different package of medications (Arms 2 and 5) as compared to current standard care, which the investigator believe will have greater benefit. The RUTF will be a new formula in two of the arms (3 and 5) based on research into what composition will improve health outcomes for children with complicated SAM. This will be a variant on Plumpy'Nut®, a brand that is known and trusted, produced in collaboration with the manufacturers, Nutriset.
The Psychosocial intervention (Arms 4 and 5) will involve three components:
i) The Friendship Bench, which was developed in Zimbabwe as a low-cost psychological intervention utilising problem-solving therapy (delivered by trained lay workers) and peer-to-peer support to address depression and other common mental disorders. There is a strong evidence-base for its use in urban LMIC settings. Peer support groups meet every 1-2 weeks and focus on communal problem solving, and establishing income-generation activities (such as making bags). ii) Care for Child Development is a UNICEF package that helps families build stronger relationships and solve problems in caring for the child at home, through play and communication activities to stimulate children, through a series of age-appropriate interactive modules delivered by a lay worker using 'flash' cards. It has been used in other African contexts and has good acceptability. iii) Educational and behavior-change messages around better nutrition; play for children with SAM; stigma, HIV and gender-based violence; financial planning; causes of SAM; and health-seeking behaviours.
Blood and stool will be collected at baseline, 12 and 24 weeks from all children to explore recovery of underlying pathological processes. At week 2, liver function tests will be undertaken in local laboratories. Samples will also be transported to Kenya and the Netherlands for some assays not available in each country.

Active Comparator: Arm 1: Standard-of-care (control)
Children in the control arm will receive Ready to Use Therapeutic Food (RUTF) for at least 2 weeks, plus all standard care. Children with HIV will receive long-term Cotrimoxazole prophylaxis and antiretroviral therapy, as per current guidelines.
|
Other: Standard Care
All children will receive care according to WHO guidelines, which includes standard RUTF and any other medications required. |
Experimental: Arm 2: Antimicrobial package
Children will receive a bundle of azithromycin (3 days every month), isoniazid (daily), rifampicin (daily) and pyridoxine (daily) for 12 weeks.
|
Drug: Rifampicin
Rifampicin is commonly used in the first-line management of paediatric tuberculosis, and is approved by the FDA (ID: 2862628) and the EMA (EMA/31710/2020). Drug: Azithromycin Azithromycin is a macrolide antibiotic, and is approved for use in children by the FDA (ID: 3263750) and EMA (EMA/2872/2021). Drug: Isoniazid Isoniazid is an antibiotic commonly used in the firstline treatment of tuberculosis, and as tuberculosis prophylaxis. Drug: Pyridoxine Hydrochloride Pyridoxine is a form of vitamin B6 used to prevent peripheral neuropathy among children receiving isoniazid. Other: Standard Care All children will receive care according to WHO guidelines, which includes standard RUTF and any other medications required. |
Experimental: Arm 3: Reformulated RUTF
Children will receive a reformulated RUTF, with increased medium-chain triglycerides (MCTs), higher hydrolysed protein content and a more bioavailable form of selenium (selenium yeast). Children will receive RUTF for at least 2 weeks.
|
Dietary Supplement: Reformulated Ready to Use Therapeutic Food
A reformulated product designed to improve outcomes for children who have severe acute malnutrition. Other: Standard Care All children will receive care according to WHO guidelines, which includes standard RUTF and any other medications required. |
Experimental: Arm 4: Psychosocial package
Caregiver-child pairs will receive a low-cost, co-designed intervention to strengthen caregiver support, enhance income generation and promote child play. This is delivered over 12 weeks and comprises: i) The Friendship Bench, developed as a low-cost psychological intervention utilising problem-solving therapy (delivered by trained lay workers) and peer-to-peer support to address depression and other common mental disorders. ii) Care for Child Development is a UNICEF package that helps families build stronger relationships and solve problems in caring for the child at home, through play and communication activities in a series of age-appropriate interactive modules delivered by a lay worker using 'flash' cards. iii) Educational and behaviour-change messages around better nutrition; play for children with SAM; stigma, HIV and gender-based violence; financial planning; causes of SAM; and health-seeking behaviours. |
Behavioral: The Friendship Bench
The Friendship Bench was developed in Zimbabwe as a low-cost psychological intervention utilising problemsolving therapy (delivered by trained lay workers) and peer-to-peer support to address depression and other common mental disorders. There is a strong evidence base for its use in urban LMIC settings. Peer support groups meet every 1-2 weeks and focus on communal problem solving, and establishing income-generation activities (such as making bags). Behavioral: Care for Child Development Care for Child Development is a UNICEF package that helps families build stronger relationships and solve problems in caring for the child at home, through play and communication activities to stimulate children, through a series of age-appropriate interactive modules delivered by a lay worker using 'flash' cards. It has been used in other African contexts and has good acceptability. Behavioral: Educational and behaviour-change modules Educational and behaviour-change messages around better nutrition; play for children with SAM; stigma,HIV and gender-based violence; financial planning; causes of SAM; and health-seeking behaviours. These have been developed with caregivers affected by SAM in a previous study, through a series of codesign workshops, ensuring these are contextually relevant. Other: Standard Care All children will receive care according to WHO guidelines, which includes standard RUTF and any other medications required. |
Experimental: Arm 5: Antimicrobial package + reformulated RUTF + psychosocial package
A combination of all interventions from arms 2, 3 and 4, plus standard care delivered for 12 weeks.
