Brief summary: Augmentin (ES)-600 is a high-dose amoxicillin/clavulanic acid 14:1 formulation that allows administration at 90/6.4 milligrams (mg)/kilograms (kg)/day in two divided doses. Most physicians in India use the standard Augmentin (amoxicillin:clavulanic acid 7:1) (45/6.4 mg/kg/day) formulation and double the dose to achieve higher dose of amoxicillin/clavulanic acid at 90 mg/kg/day in pediatric acute otitis media (AOM) due to non-availability of Augmentin (ES)-600. Using the 7:1 formulation causes unnecessary exposure to higher proportionate dose of clavulanic acid (12.8 mg/kg/day) as a unit dose of 6.4 mg/kg/day of clavulanic acid is only required for efficacy against beta-lactamase producing AOM pathogens. Hence, there is an unmet need for availability of Augmentin (ES)-600 in India. This is an open label, single arm, multicenter, non-comparative study in participants aged 6 months to 12 years with AOM. It aims to assess the safety and clinical efficacy of Augmentin (ES)-600 administered in two divided doses, every 12 hours in pediatric population in India. AUGMENTIN is a registered trademark of the GlaxoSmithKline group of companies.


Eligibility criteria: Inclusion Criteria:

* Participants aged: 6 months to 12 years; no gender restriction.
* Diagnosis of AOM on basis of otoscopic findings as defined below:

  1. Purulent otorrhea of less than 24 hours duration or
  2. Middle ear effusion
* Middle ear effusion is evidenced by at least two of the following:

  1. Decreased or absent tympanic mobility measured by pneumatic otoscopy,
  2. Yellow or white discoloration of the tympanic membrane, or
  3. Opacification of the tympanic membrane plus

At least one of the following indicators of acute inflammation:

1. Ear pain within 24 hours, including unaccustomed tugging or rubbing of ear,
2. Marked redness of the tympanic membrane, or
3. Distinct fullness or bulging of the tympanic membrane.

   * The participant and parent(s)/legal guardian(s) are willing and able to comply with the study protocol.
   * In accordance with regional/local laws and regulations, the parent(s)/legal guardian(s) has given signed informed, dated consent; and the participant has given written assent, if applicable, to participate in the study.

Exclusion Criteria:

* Weight more than 40 kg.
* Spontaneous perforation of the tympanic membrane and drainage for longer than 24 hours.
* Tympanoplastic tube(s) in place, or has anatomic abnormalities associated with recurrent AOM, prolonged middle ear effusion, including cleft palate or repair, high-arched palate or Down's syndrome.
* A serious underlying disease as per clinician's judgment.
* Concomitant infection which would preclude evaluation of the response of his/her acute otitis media to the study intervention.
* Pre-existing renal insufficiency (plasma creatinine greater than \[\>\]1.5 times upper limit of normal range for age).
* Pre-existing liver disease(s) and/or hepatic dysfunction.
* Evidence of leukopenia and/or thrombocytopenia.
* History of previous hypersensitivity reaction to penicillins, cephalosporins or other beta-lactam antibiotics.
* History of Augmentin-associated cholestatic jaundice/hepatic dysfunction.
* History of phenylketonuria or a known hypersensitivity to aspartame.
* Received, within 48 hours of study entry, or is scheduled to receive during the study period, any medication which may alter bowel function.
* Currently receiving or has received more than one dose of systemic antibiotic therapy within one week prior to the initiation of the study. AOM treatment failures with Amoxicillin, erythromycin, sulfamethoxazole or Trimethoprim-Sulfamethoxazole are not subject to this criterion.
* Receipt of an investigational compound (non-Food and Drug Administration \[FDA\] and non- Drugs Controller General Of India \[DCGI\] approved) or device within the previous 30 days or five half-lives, whichever is longer, preceding the first dose of study intervention or during the study.
* Participants with symptoms suggestive of active Coronavirus Disease 2019 (COVID-19) infection (fever, cough, etc).
* Participants with known COVID-19 positive contacts within the past 14 days.
