Study to Evaluate the Safety and Tolerability of Single-Dose Intravenous (IV) Oritavancin
Study Details
Study Description
Brief Summary
This protocol describes a randomized, open-label study to evaluate the safety and tolerability of single-dose intravenous (IV) oritavancin diphosphate (oritavancin) versus standard of care (SoC) antibiotics for the treatment of pediatric subjects with acute bacterial skin and skin structure infections (ABSSSIs).
This study involves two oritavancin products, ORBACTIV® and KIMYRSATM. Oritavancin is the active drug substance in both ORBACTIV and KIMYRSA. This study protocol distinguishes the differences between ORBACTIV and KIMYRSA by providing product-specific data, and information and guidance for Investigators. "Oritavancin" is used to describe drug product data, and information and guidance that is not specific to ORBACTIV or KIMYRSA (i.e., applies to both).
The study involves pharmacokinetic (PK) sampling and will evaluate clinical outcome assessments. The study was designed to capture adequate data while minimizing the impact to subjects and their caregivers.

Outcome Measures
Primary Outcome Measures
- Safety Assessments [28 Days]
Adverse events (AEs)
Secondary Outcome Measures
- Test of Cure [Day 28]
All-cause mortality
- Clinical Outcome Assessments [EoT Day 14; ToC Day 28]
Clinical Outcome Definitions: Cure or failure at End of Treatment visit and Test of Cure visit. Cure Complete or nearly complete resolution of baseline signs and symptoms of the primary infection, including absence of fever No further treatment with antibiotics required for the primary infection Failure Use of additional antibiotic treatment for the primary infection prior to the visit (other than for gram-negative coverage, when given according to this protocol) Worsening signs and symptoms (either assessed by the investigational site or reported by the subject or subject's caregivers) of the primary infection >72 hours from the start of Study Drug treatment. Lost to Follow-up or other extenuating circumstance where the subject cannot be adequately assessed
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Male or female, 3 months to <18 years of age at randomization
-
Diagnosis of at least one of the following ABSSSI infections (known or suspected to be caused by a gram-positive pathogen):
-
Wound infection: that is either traumatic or surgical in origin, defined as an infection characterized by purulent drainage from a wound with surrounding erythema, edema, and/or induration
-
Cellulitis/erysipelas: a diffuse skin infection characterized by spreading areas of erythema, edema, and/or induration
-
Major cutaneous abscess: an infection characterized by a collection of pus within the dermis or subcutaneous tissue that is accompanied by surrounding erythema, edema, and/or induration
-
ABSSSI must present with at least two of the following signs and symptoms:
-
Purulent drainage or discharge
-
Erythema (>1 cm beyond edge of wound or abscess)
-
Fluctuance
-
Heat or localized warmth
-
Edema/induration
-
Pain or tenderness to palpation AND at least one of the following signs of systemic inflammation:
-
Proximal lymph node swelling and tenderness
-
Increased temperature (>38.0°C [>100.4°F])
-
Decreased temperature (<36.0°C [<96.8°F])
-
Decreased white blood count (WBC) (<4000/mm3) or increased WBC (>12,000mm3)
-
Bandemia >10%
-
C-reactive protein (CRP) >upper limit of normal (ULN)
-
Written informed consent obtained from parent(s) or legal guardian(s), with written or documented verbal assent of the child obtained, when appropriate, before initiation of any assessments conducted solely for study purposes.
Exclusion Criteria:
-
Subjects who have received more than 72 hours of effective antibacterial drug therapy for treatment of the current episode of ABSSSI

-
Subjects with septic shock or hemodynamic instability
-

-
Infection suspected or documented to be caused solely by gram-negative pathogens (e.g., human or animal bite, injury contaminated with fresh or saltwater, external malignant otitis), fungi, or viruses
-
