Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - AK0529
Treatment: Drugs - Placebo

Experimental: AK0529 - Subjects will receive single or multiple doses of AK0529 at different dose levels within different cohorts.

Placebo Comparator: Placebo - Patients who are randomized to the control arm within each cohort will receive the corresponding placebo to AK0529.


Treatment: Drugs: AK0529
AK0529 is a novel compound being developed for the treatment of RSV infection. The enteric coated drug pellets with sugar core can be administered orally with apple sauce/purée or yoghurt, or by flushing with 10% dextrose water via a nasogastric or other feeding tube, or upon a glucose wafer.

Treatment: Drugs: Placebo
The placebo was made with the same smell and appearance as AK0529 but without the active ingredients. The placebo supplements are composed primarily of microcrystaline cellulose pellet.

Eligibility
Key inclusion criteria
- Male or female patients of any race or ethnicity with an age adjusted for any
prematurity of =1 month and =24 months.

- Diagnosis of RSV infection by virological means, which may include rapid diagnostic
point-of-care testing, within 96 hours preceding screening for Part 1 and 72 hours for
Part 2.

- Patient must weigh >3 kg at screening and be within the 10th and 90th percentiles
(inclusive) for the patient's age, based on the local child growth standards, i.e. the
Australian Paediatric Endocrine Group Growth Charts.

- The parent / legal guardian of the patient must have provided written informed consent
for the patient to participate.

- For patients aged <12 months, an occipito-frontal head circumference within the normal
range for age and gender.
Minimum age
1 Month
Maximum age
24 Months
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- The patient has taken, is currently taking or requires any restricted medications.

- Patient is known to be HIV-positive (or the mother, if the potential patient is a
child aged <6 months).

- Participation in an investigational drug or device study within 30 days prior to the
date of screening.

- Requires vasopressors or inotropic support at the time of enrolment.

- Concurrent gastrointestinal conditions that could, in the opinion of the investigator,
prejudice absorption of the Investigational Medicinal Product (e.g. protracted
vomiting, malabsorption syndrome, a history of necrotising enterocolitis with
consequent short gut syndrome).

- Bronchopulmonary dysplasia or chronic lung disease requiring assisted ventilation at
the time of enrolment.

- Diminished ventilatory reserve at risk for hypercapnia (e.g. pulmonary hypoplasia,
sequestration syndromes, cystadenomatoid malformation, a history of surgery for
diaphragmatic hernia).

- Left to right shunt meriting corrective therapy.

- Renal failure including renal anomalies likely to be associated with renal
insufficiency (e.g. clinical conditions of renal dysplasia, polycystic renal disease,
renal agenesis).

- Clinical evidence of hepatic decompensation (e.g. hepatic disorder with associated
coagulopathy or associated encephalopathy).

- Cerebral palsy with microcephaly, chronic or persistent feeding difficulties or
seizures.

- Symptomatic because of inborn errors of metabolism (e.g. mitochondrial disorders,
disorders of carbohydrate metabolism, glycogen storage disorders).

- Congenital or acquired immunodeficiency (e.g. congenital agammaglobulinaemia, common
variable immunodeficiency, immunosuppressive therapy other than glucocorticoid or
montelukast therapy forming part of care directed by the treating physician).

- For Part 2 of this study, children with a history of having received palivizumab or
any other monoclonal agent directed against RSV in the preceding 120 days. This
exclusion criterion does not apply to Part 1.

- Evidence of active or uncontrolled respiratory, cardiac, hepatic, central nervous
system or renal disease unrelated to RSV infection at baseline or any other medical
condition that in the opinion of the investigator renders the patient unsuitable for
enrolment.

- A history of epilepsy or seizures including febrile seizures.

- Allergy to test medication or constituents.

- Weight less than 10th percentile or greater than 90th percentile for age and gender
adjusted for any prematurity.

- The patient's parent or legally acceptable representative is an employee of the
investigator or the study center, with direct involvement in the proposed study or
other studies under the direction of that investigator of the study center, or any
family members of the employees or the investigator.

- Failure to satisfy the investigator of fitness to participate for any other reason.
