NCT04377451

Brief Summary

This study aims to investigate the effect of metformin as host-directed therapy in obese/overweight patients with dengue Primary Objective To evaluate the safety and tolerability of metformin in obese/overweight young adults and children with dengue Secondary Objectives

  • To assess the effect of metformin therapy in obese/overweight patients with dengue on physiological, clinical and virological parameters
  • To assess the immunomodulation effects of metformin therapy in obese/overweight patients with dengue
  • To assess difference in gene expression between treatment group compared to non-treatment population

Outcome Measures

Primary Outcomes (1)

    Number of severe clinical symptoms and signs, including severe diarrhoea (defined as \>5 episodes watery stool/day), severe vomiting (\>=3 episodes separated by 15 minutes/24 hours), severe abdominal pain and laboratory markers of severity including -Hypoglycaemia defined as glucose \<3.9 mmol/l, Hyperlactatemia (lactate \>3 mmol/l), ALT/AST \>400 U/l

    Up to 30 days after enrollment

  • Percentage increase in hematocrit from baseline

    Up to 30 days after enrollment

  • Percentage change in endothelial and lipid-inflammatory parameters

    Up to 30 days after enrollment

  • Changes in virological parameters

    Up to 7 days after enrollment

Study Arms (2)

Control arm

NO INTERVENTION

The control group will be formed of 60 overweight or obese dengue patients receiving standard of care

Intervention arm

EXPERIMENTAL

Two cohorts receive a 5-day course of metformin treatment. In the initial phase (cohort 1), 5 young adults and 5 children (age \<16) will receive a low dose of metformin. In the second phase (cohort 2), 25 adult and 25 paediatric patients will receive a weight-based dose of metformin.

Drug: Metformin

Interventions

The trial will be conducted in two phases, with a dose escalation of metformin. Metformin dosing will begin at 500mg (children) and 850mg (adults) once daily for 5 days in cohort 1. Cohort 2 will be received weight-based doses; 5 days of 1000mg (500mg twice daily) for those weighing \<60kg and 5 days of 1500mg (1000mg mane, 500mg nocte) for those weighing ≥60kg

Intervention arm

Eligibility Criteria

Age10 Years - 30 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • ≥ 10 years to ≤ 30 years of age,
  • Clinical diagnosis of dengue (based on WHO 2009 Dengue: Guidelines for Diagnosis, Treatment, Prevention and Control/Vietnam Ministry of Health 2019: Guidelines for Dengue Diagnosis, treatment and prevention)
  • Positive NS1 rapid test
  • ≤ 3 days (≤ 72 hours) of fever
  • BMI \> 25 Kg/m2 (or BMI-for-age \> 1 SD);
  • Written informed consent or assent to participate in the study
  • Agree to come back for follow up visit around day 21-28 of illness (maximum 1 month)

You may not qualify if:

  • In all female patients: Pregnancy Localizing features suggesting an alternative diagnosis, e.g. pneumonia, otitis etc.
  • History of hypersensitivity to metformin
  • Severe infection, including: (1) severe dengue (dengue shock syndrome, severe haemorrhage, severe organ impairment) (2) central nervous system infection, or (3) septicaemia etc…
  • Baseline lactate level \> 2.0 mmol/L
  • Baseline glucose level \< 3.9 mmol/L OR \< 70 mg/dL
  • Already taking metformin or any other regular hypoglycaemic agents, eg. insulin
  • Significant diarrhoea and/or vomiting (\> 3 episodes in 24 hours)
  • Have acute or chronic renal impairment (baseline GFR \< 30ml/min)
  • Liver impairment (baseline AST and ALT \> 250 U/L)
  • Being treated for heart failure or have had a recent heart attack (in the last year)
  • Taking any drug with significant interaction with metformin
  • The study physician judges that the patient is unlikely to attend follow up visit at around 3-4 weeks after fever onset - e.g. due to long travelling distance from the clinic
