Controlled Trial of Omadacycline Randomized Treatment Given for Bone and Joint Infection

Description

The study design is a randomized, open-label, clinical trial of omadacycline vs Standard of Care (SOC) antibiotics for bone and join infection (BJI) treatment. Study participants will have their BJI regimen chosen by their treating physicians, (typically Infectious Diseases for hardware and prosthetic joint infections, or multidisciplinary Limb Salvage team for diabetic foot infections) prior to enrollment. Then participants will be randomized to an omadacycline-containing regimen versus the a priori chosen SOC regimen. Participants must require between 4 and 12 weeks of therapy for their BJI. The exact duration of therapy will be decided by the participants' treating physician. At 12 weeks, if the treating physician wishes to extend therapy, participants receiving omadacycline will be transitioned to other SOC antibiotics. Once enrolled, participants will be followed via in-person clinic visits at the following intervals: weeks 0, 2, 4, 8, and 12. A final in-person visit will occur 2 weeks post-treatment completion. A phone survey will occur 3 months post-treatment completion. Participants in the SOC group will follow the same schedule. Oral once-daily dosing options for S. aureus and Coagulase negative Staphylococcus are essentially non-existent. Thus, omadacycline possesses a novel and advantageous option for BJI treatment. Its convenient dosing regimen will almost certainly be associated with improved adherence, and higher adherence may, in turn, improve clinical outcome. Investigators hypothesize that omadacycline will be a well-tolerated and efficacious oral antibiotic for BJIs and will be associated with improved adherence compared with standard of care oral antibiotics. Investigators believe omadacycline addresses the unmet need for an oral antibiotic that is well-tolerated and efficacious for use as a prolonged therapy for BJIs. To this aim, investigators will perform a randomized, open-label clinical trial of omadacycline to SOC antibiotics for BJIs.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 1. Pregnancy or breast feeding. Women of childbearing potential must have a negative urine or serum pregnancy test result within 1 day prior to initiation of study drug
  • 2. Hypersensitivity to tetracycline-class antibiotics
  • 3. BJI caused by fungi or mycobacteria
  • 4. BJI complicated by endocarditis, central nervous system involvement such as subdural abscess, or any foci of metastatic infection, such as renal or splenic abscesses
  • 5. Prosthetic joint infections that have not undergone both stages of two stages of surgical treatments (i.e., subjects are only eligible after the 2nd stage surgery has been completed and typically 6 weeks of IV therapy has been completed)
  • 6. Hematogenous BJI prior to adequate treatment for bacteremia (i.e., subjects are only eligible after adequate IV course of bacteremia is completed and additional oral therapy is still required for infection "mop up")
  • 7. Any medical, psychological, or social condition that, in the opinion of the Investigator, would prevent the patient from fully participating in the study or would represent a concern for study compliance or constitute a safety concern to the patient
