An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. Number of participants who experienced an AE were reported.

Hematopoietic cytopenia is a condition where there is a lower-than-normal amount of one or multiple kinds of blood cells. A standardized Medical Dictionary for Regulatory Activities (MedDRA) query for hematopoietic cytopenia was conducted. The number of participants with a hematopoietic cytopenia were reported.
Early clinical response is defined as responder if there is \>=20% reduction in the area of erythema, edema, and/or induration (length × width) of the primary acute bacterial skin and skin structure infections (ABSSSI) lesion, compared with baseline at the 48-72 Hour visit.
The numbers of participants with all-cause mortality within 28 days after randomization was determined in the ITT population. Any participants who were lost to follow-up and not known to be alive or deceased by Day 28 were imputed as deceased.
Responder: No increase in lesion surface area from baseline.
Responder: No increase in lesion surface area from baseline and oral temperature ≤37.6°C
Safety will be assessed through summaries of the incidence of AEs and SAEs as well as through summaries of vital signs, physical examinations, ECG findings, and laboratory assessments (hematology, serum chemistry, and urinalysis).

TR-701 FA is an investigational small molecule antibacterial being developed by Merck & Company, Inc. (ticker MRK) for bacterial infections. It has been studied in acute bacterial skin and skin structure infections, major cutaneous abscess, cellulitis, erysipelas, and hepatic impairment. It is not an approved product and remains in clinical development.
TR-701 FA has been studied for skin and subcutaneous tissue bacterial infections, including acute bacterial skin and skin structure infections, major cutaneous abscess, cellulitis, and erysipelas. It has also been evaluated in hepatic impairment and in pulmonary disposition studies in bacterial infection. These uses remain investigational.
TR-701 FA is developed by Merck & Company, Inc., which trades under the ticker MRK. Merck sponsored the clinical program evaluating the drug across skin infection and hepatic impairment studies.
TR-701 FA is in Phase 1 development overall, though individual completed studies have reached Phase 2 and Phase 3. It is investigational and has not been approved by the FDA. The program includes three completed trials with a combined enrollment of 1,333 participants.
Three completed trials are registered for TR-701 FA: NCT01519778, a Phase 2 skin lesion measurement study in major cutaneous abscess, cellulitis, and erysipelas; NCT01431833, a Phase 1 pharmacokinetic and safety study in hepatic impairment; and NCT01421511, a Phase 3 study versus linezolid in acute bacterial skin and skin structure infections.
Yes. TR-701 FA is also referred to as TR701 FA, TR-701 FA 200 mg, TR-701 FA 1200 mg, TR-701 FA for injection, 200 mg/vial, TR-701 FA with tyramine, and TR-701 FA with PSE. These names refer to the same investigational Merck antibacterial compound.
