Summary

This is a Phase 1/2, randomized, controlled, open-label, proof-of-concept study to evaluate the safety and tolerability, local and systemic PK profiles of TNP-2092 administered via IA injection on the basis of vancomycin IV and oral antibiotics therapy in participants with early (within 1 month of TKA) or acute hematogenous (within 3 weeks of infectious symptoms) PJI requiring or not requiring DAIR therapy after TKA, or requiring long-term antibiotic suppression therapy for PJI (including PJI occurring after various joint replacements and revision surgeries).

Conditions

  • Periprosthetic Joint Infection (PJI)

Interventions

DRUG

TNP-2092 for injection

TNP-2092 for injection, 100 mg/vial, Intra-articular administration (IA), 10ml (50 mg) once daily for 14 days. TNP-2092 dose volume, dose, frequency, and duration can be adjusted according to the sentinel group synovial fluid TNP-2092 concentration, PK characteristics, and safety results at the EA visit.

DRUG

Vancomycin Hydrochloride for Injection (IA)

Vancomycin Hydrochloride for Injection, 0.5 g/vial, Intra-articular administration, 10 mL (0.5 g) once daily for 14 days.

DRUG

Vancomycin Hydrochloride for Injection (IV)

Vancomycin Hydrochloride for Injection, 0.5 g/vial, Intravenous infusion, 250 mL (1 g) q12h ± 1h per day, for 14 days.

DRUG

Oral antibiotics

Rifampicin capsules: 0.15 g/capsule. 0.45 g (3 capsules) orally once daily within 1 h before breakfast for 8 weeks (56 days). Levofloxacin Tablets: 0.5 g/tablet. 0.5 g (1 tablet) orally once daily within 1 hour before breakfast for 8 weeks (56 days). If susceptibility testing results show resistance to rifampicin and/or levofloxacin, or intolerance by the patient 's participant, treatment with oral minocycline hydrochloride capsules will be substituted as follows:Minocycline hydrochloride capsules: 100 mg/capsule. Administered orally q12h ± 1h daily, doubling the first dose, 200 mg (2 capsules) orally, then 100 mg (1 capsule) each time for 8 weeks (56 days). The total duration of oral treatment during the oral administration period was 8 weeks (56 days) regardless of whether oral medication will be changed (eg, intolerance).
