Research Excerpts

Toxicity

meropenem was associated with more frequent but less severe adverse events when compared with imipenem/cilastatin. Cilastatin can be potentially used in the clinic as a therapeutic agent to alleviate the adverse renal reaction to diclofenac.

Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-24)] of Tigecycline

AUC (0-24) = Area under the serum concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration (0-24). Area under the serum concentration-time curve was derived from the population pharmacokinetic (PK) analysis by using each participant's dose and the post-hoc individual estimated systemic CL, AUC (0-12) = Dose divided by CL. Model-predicted AUC (0-24) was calculated by multiplying AUC (0-12) by 2. (NCT00707239)

Number of Participants With Adverse Events (AE) and Serious Adverse Events (SAE)

AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e., lack of efficacy), abuse or misuse. SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect or is medically significant.

Number of Participants With Abnormal Electrocardiogram (ECG) Findings

Twelve lead ECGs were obtained during the study using an ECG machine that automatically measured PR, QRS, QT, and QT corrected by Bazett's formula (QTcB), QT corrected by Fridericia's formula (QTcF) intervals. Twelve lead ECGs were performed with the participant in a semi-supine position having rested in this position for at least 10 minutes beforehand. Measurements that deviated substantially from previous readings were repeated immediately. Three measurements were taken at pre-dose on Day 1 at least 5 min apart. One additional ECG measurement was taken after completion of the first infusion of study medication. Two ECG measurements (pre and post-1st infusion of the day) were taken on Day 4 while the participant was on IV therapy. When there was an abnormal finding, two more were taken and the mean PR interval, QRS duration, QT interval and QTcB were calculated from automated ECG readings. One ECG measurement was taken at the early safety follow-up visit. (NCT01381549)

The therapeutic response was the combination of a participant's clinical and microbiological response. It was assessed at the Test of Cure visit in participants who have a qualifying Gram-negative uropathogen at Baseline and have had a minimum of 5 days of IV therapy. Therapeutic response was a measure of the overall efficacy response, and a therapeutic success referred to participants who have been deemed both a 'clinical success' and a 'microbiological success'. All other combinations (other than 'clinical success' + 'microbiological success') were deemed failures for therapeutic response. (NCT01381549)

Microbiological Response at the End of IV Therapy Visit, Test of Cure Visit and Late Follow-Up Visit

Microbiological response involved both microbiological success and microbiological failure. A reduction in the uropathogens in the urine culture and no growth on blood culture was termed as microbiological success. Increase in the uropathogens in the urine culture and pathogens identified in the blood culture or use of antibacterials other than study treatments were classified as microbiological failures.

Clinical Response at the End of IV Therapy Visit, Test of Cure Visit and Late Follow-Up Visit

Clinical response was a combination of clinical success and clinical failure. In clinical success, participants showed no signs and symptoms of pyelonephritis and lower complicated urinary tract infection and antibiotics are not used for the same. In clinical failure, there is reappearance of signs and symptoms of and lower complicated urinary tract infection and participant required antibiotics for the same. (NCT01381549)

Percentage of Participants With Specific AEs With Incidence of >= 4 Participants in One Treatment Group

An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product/protocol-specified procedure, whether or not considered related to the medicinal product/protocol-specified procedure. Any worsening of a preexisting condition temporally associated with the use of the product was also an AE.

Percentage of Participants With at Least 1 Adverse Event (AE)

An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product/protocol-specified procedure, whether or not considered related to the medicinal product/protocol-specified procedure. Any worsening of a preexisting condition temporally associated with the use of the product was also an AE. (NCT01505634)

Percentage of Participants Who Discontinued Study Drug Due to an Adverse Event (AE)

The percentage of participants who discontinued from study medication due to an adverse event was calculated. An AE was defined as any unfavorable and unintended sign, symptom, or disease (new or worsening) temporally associated with the use of study therapy, regardless of whether or not a causal relationship with the study therapy could be determined.

Percentage of Complicated Intra-Abdominal Infection (cIAI) Participants With Favorable Clinical Response at End of Therapy Visit

"The percentage of participants with cIAI who display a favorable clinical response at End of Therapy visit was presented. Per protocol, a subset of the cIAI/cUTI study arm was analyzed: only participants with cIAI were evaluated because clinical response is primarily relevant to cIAI. Favorable clinical response is a rating of cure or improved as determined by the investigator at the End of Therapy Visit. Cure is defined as: all pretherapy signs and symptoms of the index infection(s) have resolved (or returned to preinfection status) AND no additional intravenous antibiotic therapy is required AND no unplanned surgical or percutaneous drainage procedures have been performed. Improved is defined as: All or most pretherapy signs and symptoms of the index infection(s) have improved or resolved (or returned to preinfection status) AND no additional intravenous antibiotic therapy is required AND no unplanned surgical or percutaneous drainage procedures have been performed."

Percentage of Complicated Urinary Tract Infection (cUTI) Participants With Favorable Overall Microbiological Response at End of Therapy Visit

The percentage of participants with cUTI who display a favorable Overall Microbiological Response at the End of Therapy visit was calculated. Per protocol, only a subset of the cIAI/cUTI study arm was analyzed: only participants with cUTI were evaluated because the microbiological response evaluation is primarily relevant to cUTI. A favorable Overall Microbiological Response is defined as a urine culture taken at the End of Therapy Visit showing eradication (e.g., ≥10^5 CFU/mL is reduced to <10^4 CFU/mL) of all uropathogens found at study entry.
