E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the systemic absorption of ozenoxacin 1% cream following repeated topical applications by analysing plasma ozenoxacin concentrations in patients with impetigo. |
|
E.2.2 | Secondary objectives of the trial |
To assess the safety and tolerability of ozenoxacin 1% cream after repeated topical applications in patients with impetigo.
Clinical response at the end of therapy will also be evaluated.
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients who meet the following criteria will be considered eligible to participate in the clinical study:
1. Written informed consent.
2. Males and females, 2 months to 65 years.
3.Patients with a clinical diagnosis of non-bullous or bullous impetigo.
4.The patient has a total affected area comprised between 1-100 cm2 with surrounding erythema not extending more than 2 cm from the edge of any affected area.
5.Females of childbearing potential: negative urine pregnancy test.
6.Females: surgically sterile for at least 6 months prior to first application of the IMP; pre-menarchial or postmenopausal women who are amenorrhoeic for at least 12 months; or if of childbearing potential, must in the opinion of the investigator, be using a suitable and effective contraceptive method during the study. Females must agree not to become pregnant during the period of IMP exposure.
7.Treatment with the following agents prior to study drug administration (when applicable):
-At least one week since last systemic oral antibiotic therapy or last topical antibiotic therapy.
-At least 30 days since last long-acting injectable antibiotic.
-At least 24 h since last topical therapeutic agent. -At least 8 h since last topical antiseptic or other treatment that in the investigator’s opinion could confound the evaluation of the treatment effect on the investigational area(s) applied directly to the impetigo lesions
-At least 8 h since last administration of any systemic or topical anti-inflammatory, antihistamine or analgesic drug. |
|
E.4 | Principal exclusion criteria |
Patients who meet one or more of the following criteria will not be considered eligible to participate in the clinical study:
1. A history of hypersensitivity to the IMP or any of the excipients or to medicinal products with similar chemical structures.
2. Treatment with any other IMP in the last 12 weeks before administration of the first dose in this clinical study.
3. Pregnant or lactating women.
4. Received systemic or topical skin treatment with immunosuppressive agents within 21 days before dosing with the IMP.
5. Current medical history of uncontrolled diabetes.
6. A history of, or known current problems with, drug or alcohol abuse.
7. Vulnerable patients (e.g., persons kept in detention).
8. Any concurrent disease, condition or therapy that in the opinion of the Investigator would make the patient unsuitable for participation in the clinical study.
9. Planned treatment with antibacterial medication (other than the IMP) during the study.
10. Signs and symptoms of systemic infection.
11. Presence of skin infection not amenable to topical treatment only.
12. Have a history of or are currently being treated for active AIDS, hepatitis B or hepatitis C. |
