ERADICATE Trial
ERADICATE—one of the largest double-blind, randomized controlled clinical trials in SAB1,2
ZEVTERA demonstrated efficacy in a Phase 3 noninferiority trial2
Double-blind, randomized, multicenter, multinational, clinical trial in hospitalized adults with complicated SAB, including right-sided infective endocarditis (modified ITT population N=387)2,3

Baseline characteristics of ERADICATE trial participants
ZEVTERA was studied in patients with complicated SAB, including those with MRSA and right‑sided infective endocarditis2,3
Median age: 58 years, range 19 to 91 years; 31% aged ≥ 65 years3
69% of patients were male3
Frequent concomitant factors among trial participants with complicated SAB included3:
- 61% with acute bacterial skin and skin structure infections
- 24% with bacteremia caused by MRSA
- 14% with intra-abdominal abscesses
- 13% with osteoarticular infections
- 13% on chronic dialysis
- 6.5% with definite right-sided infective endocarditis
aComplicated SAB was defined as persistent S. aureus bacteremia (positive blood cultures despite receipt of appropriate antibiotics for ≥3 days before randomization); S. aureus bacteremia associated with long-term hemodialysis; or S. aureus bacteremia arising from soft-tissue infection, abdominal abscess, osteoarticular infection, septic thrombophlebitis, septic pulmonary embolus, epidural or cerebral abscess, or native-valve infective endocarditis on the right side of the heart (according to modified Duke criteria).2
bKey exclusion criteria included treatment with a potentially effective systemic antibiotic for more than 48 hours within the 7 days prior to randomization; concomitant infections with Gram-negative bacteria that are not susceptible to either ZEVTERA or aztreonam; severe neutropenia; or community- or hospital-acquired pneumonia.2‑4
cOverall success was defined as survival, symptom improvement, SAB clearance, absence of new SAB-related complications, and no use of other potentially effective antibiotics.2
dMicrobiologic eradication was defined as no growth of S. aureus based on a negative blood culture and confirmation by ≥1 repeat negative blood culture.4
ITT, intention-to-treat; MRSA, methicillin-resistant Staphylococcus aureus; SAB, Staphylococcus aureus bacteremia.
Clinical Response
Key clinical outcomes in the ERADICATE trial2,3
ZEVTERA achieved noninferiority for overall success* compared to daptomycin ± aztreonam in the ERADICATE trial (mITT population) at PTE (post-treatment evaluation) visit at 70 days post-randomization.2,3,a
*Overall success was defined as survival, symptom improvement, SAB clearance, absence of new SAB-related complications, and no use of other potentially effective antibiotics.
aThe lower boundary of the 95% CI of the between group difference was -7.1%, which was greater than the prespecified noninferiority margin of -15%, indicating the noninferiority of ZEVTERA to daptomycin in the ERADICATE trial.2
bBetween-group difference of ceftobiprole minus daptomycin ± aztreonam using Cochran-Mantel-Haenszel weights method adjusted for actual stratum (dialysis status and prior antibacterial treatment use).3
CI, confidence interval; mITT, modified intention-to-treat; MSSA, methicillin-sensitive Staphylococcus aureus.
ZEVTERA demonstrated bloodstream clearance across both MSSA and MRSA infections2,3
Time to SAB Bloodstream Clearance in Patients with MSSA2,3
In patients with MSSA, SAB bloodstream clearance was achieved after a median of 3 days in 94% of patients in the ZEVTERA group and after a median of 4 days in 95% of patients in the daptomycin ± aztreonam group
Time to SAB Bloodstream Clearance in Patients with MSSA2,3
In patients with MSSA, SAB bloodstream clearance was achieved after a median of 3 days in 94% of patients in the ZEVTERA group and after a median of 4 days in 95% of patients in the daptomycin ± aztreonam group
Safety
ZEVTERA—consistent safety and tolerability3*
The safety of ZEVTERA has been evaluated in 835 adult patients across three Phase 3 clinical trials.3
In the 42-day treatment period in the ERADICATE trial†, the most common adverse reactions occurring in > 2% of patients receiving ZEVTERA included3:
aAnemia includes: Anemia, Hemoglobin decreased, Hypochromic anemia, Normochromic normocytic anemia.3
bHypokalemia replaces: Blood potassium decreased.3
cHepatic enzyme increased: Alanine aminotransferase increased, Aspartate aminotransferase increased, Blood alkaline phosphatase increased, Gamma-glutamyltransferase increased, Blood bilirubin increased, Hyperbilirubinemia.3
dBlood creatinine increased includes: Acute kidney injury, Blood creatinine increased, Creatinine renal clearance decreased, Oliguria, Renal impairment.
eHypertension includes: Hypertension, Blood pressure increased, Hypertensive crisis.
fLeukopenia includes: Leukopenia, Lymphocyte count decreased, Lymphopenia, Neutropenia, Neutrophil count decreased, White blood cell count decreased.3
gPyrexia includes: Hyperthermia, Pyrexia.3
hAbdominal pain includes: Abdominal pain upper, Abdominal tenderness.3
iFungal infection includes: Candida infection, Candida sepsis, Fungal test positive, Oral candidiasis, Vulvovaginal candidiasis, Tinea pedis.3
jDyspnea includes: Dyspnea, Respiratory distress.3
IV, intravenous
Resistance
In surveillance and clinical studies, resistance to ZEVTERA was uncommon5,6
In the ERADICATE trial, there was no resistance
development on therapy with ZEVTERA2
In the daptomycin ± aztreonam group, three patients (1.5%), two with MSSA and one with MRSA, experienced MICs increasing by at least four-fold and became non-susceptible to daptomycin
MIC, minimum inhibitory concentration.
No cross-resistance with other classes of antimicrobials has been identified3
May retain activity against certain cephalosporin-resistant pathogens
