Study to Evaluate the Efficacy and Safety of TRL1068 for the Treatment of Prosthetic Joint Infection

Approximately 75% of all clinically significant human infections are estimated to be biofilm-related. Prosthetic joint infections are a classical example of difficult to eradicate infections associated with biofilm. Most Prosthetic Joint Infection (PJI) cases are caused by staphylococcal species (\~70%) with an increasing number being antibiotic-resistant (MRSA). In the US, two-stage revision is the standard of care for replacement of an infected prosthetic joint, and is associated with substantial costs and prolonged immobility. TRL1068 is a fully human antibody that has been shown in pre-clinical studies and in the first-in-human Phase 1 study TRL1068-101 to disrupt biofilm. TRL1068 targets a highly conserved epitope on the DNABII family of bacterial DNA binding proteins that includes histone-like (HU) and integration host factor (IHF) proteins of clinically relevant Gram-positive and Gram-negative bacteria. The DNABII epitope bound by TRL1068 has no homologs in the human proteome.
