ClinConnect Summary

This clinical trial is studying a new treatment called oritavancin, which is given through an IV (intravenous) line, to see if it is safe and well-tolerated for children with acute bacterial skin infections. These infections can include things like wound infections, cellulitis (a skin infection that causes redness and swelling), or abscesses (a collection of pus). The trial will compare oritavancin to standard antibiotic treatments to determine how effective and safe it is for kids aged 3 months to under 18 years who meet specific health criteria.

To participate, children must have a confirmed bacterial skin infection and show certain signs of illness, like fever or swelling. Parents or guardians will need to give written consent for their child to join the study. If enrolled, participants can expect to receive a single dose of the study drug or standard antibiotics and will be monitored closely for any side effects. The study aims to collect important safety information while ensuring minimal disruption to the patients and their families.

Eligibility criteria

• Inclusion Criteria:
• • 1. Male or female, 3 months to \<18 years of age at randomization
• 2. Diagnosis of at least one of the following ABSSSI infections (known or suspected to be caused by a gram-positive pathogen):
• • 1. 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
• • 2. Cellulitis/erysipelas: a diffuse skin infection characterized by spreading areas of erythema, edema, and/or induration
• • 3. 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
• 3. ABSSSI must present with at least two of the following signs and symptoms:
• • 1. Purulent drainage or discharge
• • 2. Erythema (\>1 cm beyond edge of wound or abscess)
• • 3. Fluctuance
• • 4. Heat or localized warmth
• • 5. Edema/induration
• 6. Pain or tenderness to palpation AND at least one of the following signs of systemic inflammation:
• • <!-- -->
• • 1. Proximal lymph node swelling and tenderness
• • 2. Increased temperature (\>38.0°C \[\>100.4°F\])
• • 3. Decreased temperature (\<36.0°C \[\<96.8°F\])
• • 4. Decreased white blood count (WBC) (\<4000/mm3) or increased WBC (\>12,000mm3)
• • 5. Bandemia \>10%
• • 6. C-reactive protein (CRP) \>upper limit of normal (ULN)
• • 4. 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:
• • 1. Subjects who have received more than 72 hours of effective antibacterial drug therapy for treatment of the current episode of ABSSSI
• • 2. Subjects who have received a glycopeptide antibiotic (e.g., vancomycin, telavancin, teicoplanin) within 24 hours of randomization
• • 3. Subjects who have received dalbavancin within 45 days prior to randomization
• • 4. Subjects who have been treated with oritavancin within the last 50 days
• • 5. Subjects with infection suspected to be associated with a device or implant
• • 6. Subjects with septic shock or hemodynamic instability
• 7. Subjects with ABSSSI due to, or associated with any of the following:
• • 1. 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
• • 2. Wound infection (surgical or traumatic) or abscess with only gram-negative pathogens
• • 3. Concomitant infection at another site, not including a secondary ABSSSI lesion (e.g., septic arthritis, endocarditis, osteomyelitis).
• • 4. Infected burn
• • 5. Primary infection superimposed on a pre-existing skin disease with associated inflammatory changes, e.g., atopic dermatitis, eczema
• • 6. Any evolving necrotizing process (e.g., necrotizing fasciitis), gangrene, or infection suspected or proven to be caused by clostridioides species (e.g., crepitance on examination of the ABSSSI site and/or surrounding tissue(s), radiographic evidence of subcutaneous gas in proximity to the infection)
• • 7. Clinically significant viral infection (e.g., influenza, COVID-19) which, in the Investigator's judgement, will impact the study clinical outcome assessments (e.g., subject is febrile due to the viral infection)
• • 8. Subjects currently receiving chronic systemic immunosuppressive therapy
• • 9. Subjects with neutropenia, defined as absolute neutrophil count (ANC) \<500 cells/mm3
• 10. Creatinine clearance (CrCl) \< 30 mL/min/1.73 m2 as calculated using the updated Schwartz bedside formula:
• • eGFR = k x (height in cm) ÷ serum Creatinine k = 0.33 in pre-term infants. k = 0.45 in term infants to 1 year of age. k = 0.55 in children and adolescent girls. k = 0.70 in adolescent boys
• • 11. Menstruating females with a positive result for the urine or serum human chorionic gonadotropin (HCG) test administered at screening
• • 12. Females of childbearing potential (and males with female partners of childbearing potential) unwilling to practice abstinence or use at least two methods of contraception (e.g., oral contraceptives, barrier methods, approved contraceptive implants) during the entire study period
• • 13. Subjects with a history of infusion-related immunoglobulin E (IgE)-mediated allergic reaction or hypersensitivity reaction to glycopeptides (e.g., vancomycin, telavancin, dalbavancin, oritavancin, teicoplanin) or any of their excipients
• • 14. Subjects who are taking heparin (other than heparin flush for line patency) or warfarin, and/or require anticoagulant monitoring \[activated partial thromboplastin time (aPTT), prothrombin time (PT), international normalized ratio (INR)\]
• • 15. Subjects receiving treatment with an investigational medicinal product or investigational device within 3 months before enrollment or during the study
• • 16. Subjects whom the investigator considers unlikely to adhere to the protocol, comply with Study Drug administration, or complete the clinical study (e.g., unlikely to survive 28 days from initiation of Study Drug)
• • 17. Subjects with alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \>3x ULN or total bilirubin ≥2x ULN.
