E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To obtain pharmacokinetic data on amoxicillin/clavulanate and time above MIC
(T>MIC) for amoxicillin when AUGMENTIN XR (amoxicillin 2000 mg/clavulanate
125 mg) is given orally twice daily to adolescents weighing at least 40 kg. |
|
E.2.2 | Secondary objectives of the trial |
To assess the safety, tolerability, and clinical response of oral AUGMENTIN XR
twice daily for 10 days in adolescent patients. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patient is a male or female who weighs at least 40 kg and is younger than 16 years
old (no older than their 16th birthday), inclusive.
2. Patients must be able to swallow AUGMENTIN XR tablets.
3. Patients with suspected acute bacterial sinusitis that may benefit from administration
of AUGMENTIN XR (in the opinion of the PI) and who are not considered to be at
risk of clinically significant adverse effects at the dose specified in the protocol.
4. Written informed consent by the patient’s parent or legal guardian and where
appropriate, written assent of the volunteer. |
|
E.4 | Principal exclusion criteria |
Definite or suspected personal history or family history of adverse reactions or
hypersensitivity or allergy to any penicillin or cephalosporin antibiotics. Also
history of reaction to multiple allergens (if considered clinically relevant by the
principal investigator).
2. Patients weighing less than 40 kg or older than 16 years of age (i.e., past their 16th
birthday).
3. Patient is participating in another clinical trial or has received or anticipates
receiving an investigational drug, vaccine, or medical device (non-government)
within 30 days (or 5-half-lives, whichever is longer) prior to the first dose of study
medication or during the conduct of the study.
4. History or presence of gastrointestinal, hepatic or renal disease or other conditions
known to or that may interfere with the absorption, distribution, metabolism or
excretion of study medication.
5. Treatment with probenecid or allopurinol within 7 days of study entry.
6. A positive urine β-hCG (human chorionic gonadotropin) test at screening (female
patients only) indicating pregnancy.
7. Female patients who are lactating (breast feeding).
8. Female patients who are unwilling to be abstinent until completion of the follow-up
visit.
9. History of diarrhea due to Clostridium difficile following treatment with antibiotics.
10. History of hypersensitivity or allergy to heparin or related preparations (if the
clinical research unit uses heparin to maintain intravenous cannula patency).
11. Patient is diagnosised with mononucleosis.
12. Estimated Glomerular Filtration Rate (GFR) <40 ml/min (refer to SRM for GFR
calculation formula).
13. Any condition, which in the opinion of the investigator, contraindicates the
administration of AUGMENTIN XR. |

E.5 End points |
E.5.1 | Primary end point(s) |
Pharmacokinetic parameters will be T>MIC for amoxicillin (for an amoxicillin MIC of 2
ug/mL and 4ug/mL), Cmax, tmax, t1/2, AUC(0-t), AUC(0-τ), and AUC(0-∞) for
amoxicillin and for clavulanate. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
T>MIC: over the 12 hour dosing interval for an MIC of 2ug/mL and 4ug/mL
All the other parameters: evaluated for patients on any one given dosing day in which Augmentin XR was administered over a 12 hour dosing period with samples at pre-dose 0.5, 1, 1.5, 2, 4, 5, 6, 7, 8, 10 and 12 hours after the administration of study medication |
|
E.5.2 | Secondary end point(s) |
Adverse experiences will be monitored throughout the study by spontaneous
patient/parent-guardian reporting, direct questioning and physician/nursing observation,
clinical responses, and clinical laboratory tests. |
