Description

tedizolid phosphate: a prodrug of DA-7157; structure in first source [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

tedizolid phosphate : A phosphate monoester resulting from the formal condensation of equimolar amounts of phosphoric acid with the hydroxy group of tedizolid . It is a prodrug of tedizolid, used for the treatment of acute bacterial skin infections caused by certain susceptible bacteria, including Staphylococcus aureus (including methicillin-resistant strains (MRSA) and methicillin-susceptible strains), various Streptococcus species, and Enterococcus faecalis.

Clinical Response at Test of Cure (TOC) Visit in the Clinically-Evaluable (CE) Population

The clinical response in the CE population at the TOC visit (derived from the Investigator's assessment at the EOT and TOC visits) was determined by the investigator to be either: clinical success, clinical failure, or indeterminate. Clinical success was declared when most or all clinical signs were completely resolved, with no new signs of infection, no additional antibiotic therapy was required, and the participant was alive. Indeterminate was declared when the investigator could not determine success or failure. Clinical failure was declared with progression, relapse, or recurrence of new symptoms of infection, or a persistence or insufficient improvement in signs and symptoms of VNP. (NCT02019420)

Dose Normalized Area Under the Plasma Concentration Time Curve (AUC) of Tedizolid (Active Metabolite) From Time Zero to Infinity

The area under the plasma concentration time curve (AUC) of tedizolid (active metabolite) from time zero to infinity following administration of IV or oral dose, normalized to dosage, was calculated. Per protocol, this outcome used pooled groups as follows: The IV Group pooled Groups 1 and 2, who received tedizolid phosphate via intravenous (IV) administration; the Oral Group pooled groups 3 and 4, who received tedizolid phosphate via oral administration. Pharmacokinetic sampling occurred at the following time points: Group 1 (part of the IV Group): Day 1 immediately after infusion and 1.5, 2, 3, 4, 6, 12, and 24 hours; Group 2 (part of the IV Group): Day 1 immediately after infusion and 3, 6, 12, 24 and 48 hours; Group 3 (part of the Oral Group): Day 1 at 1, 2, 3, 4, 6, 8, 12, and 24 hours after oral dose; Group 4 (part of the Oral Group): Day 1 at 3, 6, 9, 12, 24 and 48 hours after oral dose. (NCT02750761)
Timeframe: IV: immediately after the end of the infusion, and various time points up to 48 hours after the start of infusion as described above. Oral: at various time points up to 48 hours after the dose as described above.

"Number of Participants With an Outcome of Cure as Defined as no Need for Further Antibiotics Beyond the Originally Planned Duration Determined by the Participant's Primary/Treating Physician."

Study Hypothesis: Tedizolid is effective for the treatment of bone and joint infection. Specifically, cure will be defined as no need for further antibiotics beyond the originally planned duration (i.e., 6 weeks for non-device associated bone and joint infection or until hardware removal for subjects with implants). Unplanned surgical procedures prompted by inadequate infection control will be categorized as treatment failure. We will also measure long-term cure by performing a phone survey 3 months after completion of antibiotics. Recurrence of signs or symptoms of bone and joint infection will be considered not a long-term treatment cure (i.e., failure). (NCT03009045)
