Amoxicillin clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

The OPTIMAL TDM Study: Determining Optimal Beta-lactam Plasma Concentrations Through Therapeutic Drug Monitoring

OPTIMAL TDM

Start date: January 14, 2019
Phase:
Study type: Observational

Little is known of beta-lactam antibiotics' true therapeutic plasma concentration range. The aims of this study are to define evidence-based, safe and effective upper and lower limits of the plasma concentrations of imipenem, meropenem, amoxicillin, flucloxacillin, piperacillin, ceftazidime and cefepime in patients at increased risk of serious bacterial infections and currently understudied pharmacokinetics (the critically ill, the elderly, and the immunosuppressed). This prospective observational study will include adult patients with suspected or confirmed systemic bacterial infection receiving one of the above-named antibiotics and hospitalized in intensive-care, step-down, or hematology-oncology units of the Geneva University Hospitals (HUG). Eligible patients will be identified via the electronic health record (EHR). Patients receiving traditional intermittent dosing or prolonged infusions will undergo TDM for at least one intermediate (mid-interval) and one trough level at 24 hours (-12 or +48 hours) after the therapy's start. Patients receiving continuous infusions will undergo TDM for at least one steady-state level. Clinical course will be observed for 30 days from the start of the study antibiotic (1st day of study antibiotic =day 1). The primary outcome is incidence of clinical toxicity through day 30 after start of study antibiotic (as stratified by BL trough concentration). Secondary outcomes are listed below.
