Antibiotic lock therapy for salvaging catheters that cause bloodstream infections

Mino-Lok® is an antibiotic lock solution used to treat patients with catheter-related bloodstream infections (CRBSIs) and central line associated bloodstream infections (CLABSIs). CRBSIs/CLABSIs are life-threatening conditions, especially in cancer patients receiving therapy through central venous catheters (CVCs) and in hemodialysis patients where venous access presents a challenge.

Mino-Lok® is intended to salvage the CVC, avoiding the need to remove and replace the infected catheter. Currently, there are few alternatives to removing and replacing a CVC once it becomes infected. Studies show that removal and reinsertion of CVCs have a 15% to 20% complication rate, including pneumothorax, misplacement, and arterial puncture. Mino-Lok® is being developed to address the complications, discomfort and cost of CVC removal and replacement. The are currently no FDA-approved products to salvage infected CVCs.

Program Highlights

  • Mino-Lok® is the first & only therapy under investigation to salvage infected CVCs
  • In a Phase 2b trial, Mino-Lok® demonstrated a 100% efficacy rate in salvaging colonized CVCs; Mino-Lok® had no significant adverse events compared to an 18% serious adverse event rate when infected CVCs were removed and replaced. Learn more…
  • A multicenter Phase 3 pivotal superiority trial is currently underway. Learn more…
  • Mino-Lok® was granted QIDP and Fast Track designation by the FDA and has patent protection through 2024 and formulation patent protection through 2036
  • Citius licensed the worldwide rights to Mino-Lok® from The University of Texas MD Anderson Cancer Center

How it works

Mino-Lok® contains a proprietary combination of minocycline, edetate (disodium EDTA), and ethyl alcohol, all of which act synergistically to break down bacterial biofilms, eradicate the bacteria, provide anti-clotting properties to maintain patency in CVCs, and salvage the indwelling catheter. Mino-Lok® is used in two-hour locking cycles, allowing the CVC to be used for its intended purposes for the remaining 22 hours each day.
