Mino-Lok Therapy (MLT) for the Treatment of CRBSI/CLABSI

Status unconfirmed · Phase 3

Conditions studied: Catheter-related Infections

In brief

This is a Phase 3, multi-center, randomized, open-label, assess-blind study to determine the efficacy and safety of MLT, a novel antibiotic lock therapy that combines minocycline with edetate disodium in 25% ethanol solution as an adjuctive therapy for the treatment of catheter-related or central line associated bloodstream infection (CRBSI/CLABSI). Approximately 144 subjects who have been diagnosed with CRBSI/CLABSI and who meet all necessary criteria for the study will be randomized in a 1:1 ratio to 1 of 2 treatment arms: * MLT Arm: Mino-Lok therapy; or * Control Arm: Antibiotic lock (±heparin). The antibiotic lock (ALT) should be comprised of the best available therapy at the sites based on standard institutional practices or recommendations from the Infectious Diseases Society of America (IDSA) guidelines.

Who can join

Age: 12 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subject or a legally authorized representative must provide a signed informed consent form;
• Male or female at least 12 years of age;
• Subject must have a bloodstream infection with no other apparent source other than the CVC that meets one of the following criteria:
• A recognized single pathogen cultured from 1 or more blood cultures; OR
• A common skin contaminant cultured from 2 or more blood cultures drawn on the same or consecutive calendar days from a subject with fever (greater than or equal to 38.0 degrees C), chills, or hypotension (systolic blood pressure less than 90 mmHg); NOTE: When possible, it is recommended to collect from both the CVC and peripheral venipuncture.
• Inpatient or outpatient with presence of indwelling CVC (ie, totally implantable port, tunneled or non-tunneled CVC, hemodialysis catheter, or peripherally inserted CVC) that has been in place for at least 5 days;
• A bloodstream infection documented within 96 hours prior to enrollment (and from which an isolate of the baseline pathogen(s) is still available for analysis at the central laboratory) and demonstrates the protocol definition of CRBSI or CLABSI;
• NOTE: Subjects may be enrolled and randomized while awaiting results of standard blood cultures from the local laboratory:
• If an organism has been identified from blood specimen testing using an FDA-cleared rapid diagnostic test (eg, T2MR®); or
• If a positive blood culture specimen shows an organism by 1 of the following:
• Gram stain; or An FDA-cleared molecular rapid diagnostic test (eg, FilmArray® BCID or Verigene®); If the pending blood culture does not confirm a qualifying organism by standard methods and an isolate is not available for testing at the central laboratory, the subject will be withdrawn from study drug treatment and managed at the Investigator's discretion.
• NOTE: Subjects with a positive blood culture identified up to 120 hours prior to enrollment and in whom the baseline pathogen is still available for analysis at the central laboratory may be considered on a case by-case basis with prior approval from the Medical Monitor.
• Subjects for whom, in the Investigator's opinion, catheter retention for the duration of the study (6 weeks) is reasonable or required;
• Female subjects of childbearing potential must have a negative urine and/or serum pregnancy test within 5 days prior to randomization;
• NOTE: The following are considered women who are NOT of childbearing potential:
• Postmenopausal (defined as no menses for at least 12 consecutive months); or
• Documented to be surgically sterile;
• Female subjects of childbearing potential and male subjects who are sexually active must agree to use a highly effective method of contraception from the time of informed consent until 30 days post dose; NOTE: Highly effective methods of contraception include hormonal contraceptives, intrauterine device, double-barrier method, partner sterility, or abstinence.
• Male subjects must agree to refrain from sperm donation throughout the duration of the study and for 90 days following the last dose of study drug; and
• Subject must be willing to comply with all study procedures, whether inpatient or outpatient, for the duration of the study.

You may not qualify if…

• Subjects with hypersensitivity or allergy to tetracycline antibiotics or edetate disodium;
• Subjects with septic shock that requires inotropic support or is unresponsive to fluid resuscitation;
• Subjects taking disulfiram at the time of randomization or who are expected to take disulfiram at any time during treatment with study drug;
• Subjects with prosthetic cardiac valves, vascular grafts, pacers, automatic implantable cardioverter-defibrillator, or other non-removable vascular foreign body, with the exception of coronary stents and peripheral stents;
• Subjects with the presence of a deep-seated intravascular source of infection (eg, endocarditis [as evidenced by vegetations on an echocardiogram or clinical suspicion] or septic thrombosis);
• Subjects with bacteremia with documented microbiological evidence of another source of infection (eg, osteomyelitis, pneumonia, skin infection, urinary tract infection, joint infection, or abdominal infection) known to be due to the same organism cultured from the blood;
• Subjects with polymicrobial CRBSI/CLABSI caused by pathogens that would require multiple antibiotics to be used for adequate lock therapy treatment. For example, a subject with methicillin-resistant Staphylococcus aureus and Escherichia coli requiring treatment with vancomycin and meropenem would be excluded from the study. A subject with S. aureus and Staphylococcus epidermidis, where both are identified as pathogens and where both could be treated with vancomycin, would be eligible; NOTE: If more than 1 organism is isolated, the Investigator should decide which of the organisms are pathogens and require therapy. Isolates of all organisms should be sent to the central laboratory. In the event that the subject is being treated with more than 1 systemic standard of care (SOC) anti-infective, the Investigator will specify a single antibiotic that should be used for the antibiotic lock. It is acceptable for the SOC antibiotic lock to differ from the SOC anti infectives, as necessary per local SOC.
• Subjects with the presence of a tunnel or catheter exit site infection or an infusion port pocket abscess as manifested by purulence at the exit site, or inflammation with erythema, or induration of at least 1 cm in diameter;
• Subjects who have been previously randomized into the present study;
• Subjects who are pregnant or breastfeeding;
• Subjects with proven or suspected persistent bacteremia or fungemia despite 72 hours of both systemic anti-infective therapy and lock therapy to which the infecting organism is susceptible;
• Subjects with short-term CVCs indwelling at least 5 days;
• Subjects with a central line-related mycobacterial infection or fungi other than Candida; or
• Subjects who, in the opinion of the Investigator, have a high probability of death within 3 months of randomization due to a disease process other than the CRBSI/CLABSI.
