New Antimicrobials for Gram-Positive Sustained Infections: A Comprehensive Guide for Clinicians. Pharmaceuticals (Basel) 2023; 16:1304. [PMID: 37765112 PMCID: PMC10536666 DOI: 10.3390/ph16091304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 08/30/2023] [Accepted: 09/11/2023] [Indexed: 09/29/2023] Open
Abstract
Antibiotic resistance is a public health problem with increasingly alarming data being reported. Gram-positive bacteria are among the protagonists of severe nosocomial and community infections. The objective of this review is to conduct an extensive examination of emerging treatments for Gram-positive infections including ceftobiprole, ceftaroline, dalbavancin, oritavancin, omadacycline, tedizolid, and delafloxacin. From a methodological standpoint, a comprehensive analysis on clinical trials, molecular structure, mechanism of action, microbiological targeting, clinical use, pharmacokinetic/pharmacodynamic features, and potential for therapeutic drug monitoring will be addressed. Each antibiotic paragraph is divided into specialized microbiological, clinical, and pharmacological sections, including detailed and appropriate tables. A better understanding of the latest promising advances in the field of therapeutic options could lead to the development of a better approach in managing antimicrobial therapy for multidrug-resistant Gram-positive pathogens, which increasingly needs to be better stratified and targeted.

Comparison between Ceftriaxone and Sulbactam-Ampicillin as Initial Treatment of Community-Acquired Pneumonia: A Systematic Review and Meta-Analysis. Antibiotics (Basel) 2022; 11:antibiotics11101291. [PMID: 36289949 PMCID: PMC9598877 DOI: 10.3390/antibiotics11101291] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 09/15/2022] [Accepted: 09/20/2022] [Indexed: 11/17/2022] Open
Abstract
Current guidelines recommend the use of ceftriaxone and sulbactam-ampicillin for the initial treatment of community-acquired pneumonia (CAP). However, there are no clear data on these guidelines. Therefore, this systematic review and meta-analysis aims to evaluate the effectiveness of ceftriaxone and sulbactam-ampicillin in the initial treatment of CAP. The Embase, Scopus, PubMed, Ichushi, and Cumulative Index to Nursing and Allied Health Literature databases were systematically searched from inception to July 2022. The studies included patients who received ceftriaxone or sulbactam-ampicillin as the initial antibiotic therapy for CAP. The mortality and clinical cure rates were evaluated. Of the 2152 citations identified for screening, four studies were included. Results of the pooled analysis indicated no significant differences in the mortality and clinical cure rates between patients treated with ceftriaxone and those treated with sulbactam-ampicillin (mortality, odds ratio [OR]: 1.85, 95% confidence interval [CI]: 0.57–5.96; clinical cure rate, OR: 1.08, 95% CI: 0.18–6.44). This study supports the guidelines for CAP treatment, though further studies are needed to obtain a deeper understanding.

Abstract
Background Ceftriaxone (CTRX) and ampicillin/sulbactam (ABPC/SBT) are recommended by various guidelines as the first-line antibiotics for community-acquired pneumonia (CAP). However, which of these antibiotics is more effective for treating non-aspiration CAP remains unclear. Methods This study was a prospective, single-center, open-label, quasi-randomized controlled trial. Patients with adult CAP without risk for aspiration were allocated to either a CTRX or ABPC/SBT group based on the date of hospital admission. Macrolide was added to patients in each group. The primary outcome was the clinical response in the validated per-protocol (VPP) population at end of treatment (EOT). The secondary outcomes were clinical response during treatment and at end of study (EOS) in the VPP population, and mortality rate at day 30 in the modified intention-to-treat (MITT) population. Results Of 696 screened patients, 433 patients were excluded and 263 patients were allocated to receive either of the treatments. Males comprised 54% of patients and mean age and PSI were 62.1 ± 19.8 years and 69.3 ± 30.0, respectively, with 124 patients allocated to the CTRX group and 138 patients allocated to the ABPC/SBT group. The clinical effectiveness rate for the VPP population at EOT was 90% in the CTRX and 96% in the ABPC/SBT group (p = 0.072, 95% confidence interval [CI] of risk difference [RD]: − 12.6–0.8%). No significant difference in effectiveness at day 4 was observed between the CTRX and ABPC/SBT groups (p = 0.079, 95%CI of RD: − 12.1–0.4%), but at day 7, ABPC/SBT was significantly more effective than CTRX in the VPP population (p = 0.047, 95%CI of RD: − 13.3–-0.4%). No significant difference in late response at EOS was seen between CTRX and ABPC/SBT groups: cure (89 [86%] and 102 [94%]), relapse (5 [5%] and 1 [1%]) and failure (10 [10%] and 5 [5%]; p = 0.053). Deaths within 30 days in MITT population was higher in CTRX group (4 [3%]) than in ABPC/SBT group (0 [0%]) (p = 0.048, 95%CI of RD: 0.1–6.3%). Conclusion No significant difference in effectiveness was found between ABPC/SBT and CTRX at EOT. However, ABPC/SBT might be more effective in the early phase of treatment.

Abstract
Intravenous ceftaroline fosamil (Zinforo™), a prodrug that is rapidly converted to its active metabolite ceftaroline, is approved for use in adults and children (from 2 months of age) with complicated skin and soft tissue infections (cSSTIs) or community-acquired pneumonia (CAP). In several multinational trials, ceftaroline fosamil was an effective and generally well tolerated treatment in adult and paediatric patients with cSSTIs or CAP. In the phase 3 CANVAS trials, ceftaroline fosamil treatment was noninferior to vancomycin plus aztreonam in adults with cSSTIs. Based on a meta-analysis of three similarly designed, phase 3 trials (FOCUS 1, FOCUS 2 and an Asian trial), ceftaroline fosamil treatment was superior to ceftriaxone in adults with CAP of Pneumonia Outcomes Research Teams (PORT) risk class III or IV. Ceftaroline fosamil was also associated with high clinical cure rates in hospitalized children (aged 2 months to 17 years) with cSSTIs or CAP. With its broad spectrum of in vitro activity against clinically relevant Gram-positive [including methicillin-resistant Staphylococcus aureus (MRSA) and drug-resistant Streptococcus pneumoniae isolates] and Gram-negative pathogens implicated in cSSTIs and CAP, ceftaroline fosamil is an important treatment option for cSSTI and CAP in adults and children from the age of 2 months.

Abstract
Ampicillin-ceftriaxone combination therapy has become a predominant treatment for serious Enterococcus faecalis infections, such as endocarditis. Unfortunately, ceftriaxone use is associated with future vancomycin-resistant enterococcus colonization. We evaluated E. faecalis in an in vitro pharmacodynamic model against simulated human concentration-time profiles of ampicillin plus ceftaroline, cefepime, ceftriaxone, or gentamicin. Ampicillin-cefepime and ampicillin-ceftaroline demonstrated activities similar to those of ampicillin-ceftriaxone against E. faecalis.

Abstract
The genus Lactobacillus is a taxonomically complex and is composed of over 170 species that cannot be easily differentiated phenotypically and often require molecular identification. Although they are part of the normal human gastrointestinal and vaginal flora, they can also be occasional human pathogens. They are extensively used in a variety of commercial products including probiotics. Their antimicrobial susceptibilities are poorly defined in part because of their taxonomic complexity and are compounded by the different methods recommended by Clinical Laboratory Standards Institute and International Dairy Foundation. Their use as probiotics for prevention of Clostridium difficile infection is prevalent among consumers worldwide but raises the question of will the use of any concurrent antibiotic effect their ability to survive. Lactobacillus species are generally acid resistant and are able to survive ingestion. They are generally resistant to metronidazole, aminoglycosides and ciprofloxacin with L. acidophilus being susceptible to penicillin and vancomycin, whereas L. rhamnosus and L. casei are resistant to metronidazole and vancomycin.

Abstract
Objective: To review the treatment of methicillin-resistant Staphylococcus aureus (MRSA)–associated acute pulmonary exacerbations (APEs) in cystic fibrosis (CF). Data Sources: A search of PubMed, MEDLINE, Cochrane Library and Clinicaltrials.gov databases through November 2014 was conducted using the search terms Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, pulmonary exacerbations, and cystic fibrosis. Study Selection and Data Extraction: All English-language research articles, case reports, and case series were evaluated. A total of 185 articles were identified related to MRSA and CF; 30 articles that studied treatments of MRSA APE in CF were included. Data Synthesis: The persistent presence of MRSA in the respiratory tract of patients with CF has been associated with higher morbidity and an increased risk of death. Limited clinical data exist supporting the efficacy of any specific antimicrobial currently available for the treatment of APE secondary to MRSA. Conclusions: Data extrapolated from other populations suggest that vancomycin and linezolid are appropriate first-line treatment options for the treatment of APE secondary to MRSA. Second-line options include doxycycline or minocycline and trimethoprim/sulfamethoxazole, each of which may be useful in patients coinfected with other respiratory pathogens, for which they may provide overlapping coverage. Ceftaroline and ceftobiprole are newer antibiotics that appear to have a potential role in the treatment of APE in CF, but the latter is not currently available to the US market. Although potentially useful, clindamycin is limited by high rates of resistance, telavancin is limited by its toxicity profile, and tigecycline is limited by a lack of demonstrated efficacy for infections that are similar to that seen in the CF population. Studies investigating the clinical utility of the above-cited antibiotics for APE in CF secondary to MRSA are desperately needed to broaden the treatment armamentarium for this medical condition.

Abstract
Ceftaroline has been approved for acute bacterial skin infections and community-acquired bacterial pneumonia. Limited clinical experience exists for use outside these indications. The objective of this study was to describe the outcomes of patients treated with ceftaroline for various infections. Retrospective analyses of patients receiving ceftaroline ≥72 h from 2011 to 2013 were included. Clinical and microbiological outcomes were analyzed. Clinical success was defined as resolution of all signs and symptoms of infection with no further need for escalation while on ceftaroline treatment during hospitalization. A total of 527 patients received ceftaroline, and 67% were treated for off-label indications. Twenty-eight percent (148/527) of patients had bacteremia. Most patients (80%) were initiated on ceftaroline after receipt of another antimicrobial, with 48% citing disease progression as a reason for switching. The median duration of ceftaroline treatment was 6 days, with an interquartile range of 4 to 9 days. A total of 327 (62%) patients were culture positive, and the most prevalent pathogen was Staphylococcus aureus, with a frequency of 83% (271/327). Of these patients, 88.9% (241/271) were infected with methicillin-resistant S. aureus (MRSA). Clinically, 88% (426/484) achieved clinical success and hospital mortality was seen in 8% (40/527). While on ceftaroline, adverse events were experienced in 8% (41/527) of the patients and 9% (28/307) were readmitted within 30 days after discharge for the same infection. Patients treated with ceftaroline for both FDA-approved and off-label infections had favorable outcomes. Further research is necessary to further describe the role of ceftaroline in a variety of infections and its impact on patient outcomes.

Abstract
The in vitro activities of ceftaroline-avibactam, ceftaroline, and comparative agents were determined for a collection of bacterial pathogens frequently isolated from patients seeking care at 15 Canadian hospitals from January 2010 to December 2012. In total, 9,758 isolates were tested by using the Clinical and Laboratory Standards Institute (CLSI) broth microdilution method (document M07-A9, 2012), with MICs interpreted by using CLSI breakpoints (document M100-S23, 2013). Ceftaroline-avibactam demonstrated potent activity (MIC90, ≤ 0.5 μg/ml) against Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca, Proteus mirabilis, Enterobacter cloacae, Enterobacter aerogenes, Serratia marcescens, Morganella morganii, Citrobacter freundii, and Haemophilus influenzae; >99% of isolates of E. coli, K. pneumoniae, K. oxytoca, P. mirabilis, M. morganii, C. freundii, and H. influenzae were susceptible to ceftaroline-avibactam according to CLSI MIC interpretative criteria for ceftaroline. Ceftaroline was less active than ceftaroline-avibactam against all species of Enterobacteriaceae tested, with rates of susceptibility ranging from 93.9% (P. mirabilis) to 54.0% (S. marcescens). All isolates of methicillin-susceptible Staphylococcus aureus (MIC90, 0.25 μg/ml) and 99.6% of methicillin-resistant S. aureus isolates (MIC90, 1 μg/ml) were susceptible to ceftaroline; the addition of avibactam to ceftaroline did not alter its activity against staphylococci or streptococci. All isolates of Streptococcus pneumoniae (MIC90, 0.03 μg/ml), Streptococcus pyogenes (MIC90, ≤ 0.03 μg/ml), and Streptococcus agalactiae (MIC90, 0.015 μg/ml) tested were susceptible to ceftaroline. We conclude that combining avibactam with ceftaroline expanded its spectrum of activity to include most isolates of Enterobacteriaceae resistant to third-generation cephalosporins, including extended-spectrum β-lactamase (ESBL)- and AmpC-producing E. coli and ESBL-producing K. pneumoniae, while maintaining potent activity against staphylococci and streptococci.

Abstract
Ceftaroline is a novel cephalosporin with a favorable tolerability profile and broad in vitro activity against many resistant Gram-positive and common Gram-negative organisms. Ceftaroline fosamil is the first cephalosporin to be approved by the United States Food and Drug Administration (FDA) for the treatment of adults with acute bacterial skin and soft tissue infections, including those caused by methicillin-resistant Staphylococcus aureus (MRSA). It is also approved by the FDA for the treatment of adults with community-acquired bacterial pneumonia, including cases caused by Streptococcus pneumoniae (with or without concurrent bacteremia), although there are no data at this time to support the use of ceftaroline fosamil for the treatment of pneumonia caused by MRSA. Ceftaroline fosamil is likewise approved by the European Commission for the treatment of adults with complicated skin and soft tissue infections or community-acquired pneumonia. This review summarizes the pharmacokinetic and microbiologic properties of ceftaroline, as well as the safety and efficacy data that led to its approval by the FDA in 2010 and the European Commission in 2012. Future directions to be addressed are also highlighted.

Abstract
Ceftaroline, the active metabolite of the prodrug ceftaroline fosamil (Zinforo, Teflaro), is an advanced-generation, parenteral cephalosporin with broad-spectrum antibacterial activity in vitro against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and multidrug resistant Streptococcus pneumoniae and Gram-negative bacteria, including Haemophilus influenzae and Moraxella catarrhalis, but not Pseudomonas aeruginosa. Ceftaroline has demonstrated a low potential for the selection of resistance in vitro for drug-resistant Gram-positive organisms, including MRSA, as well as for Gram-negative respiratory pathogens. In pivotal phase III studies, intravenous ceftaroline fosamil demonstrated noninferiority to intravenous vancomycin plus aztreonam in patients hospitalized with complicated skin and soft tissue infections (cSSTIs) and intravenous ceftriaxone in patients hospitalized with community-acquired pneumonia (CAP) [Pneumonia Outcomes Research Team (PORT) risk class III or IV]; however, patients with CAP admitted to the intensive care unit were not evaluated. Ceftaroline fosamil was generally well tolerated in these trials, with an adverse event profile similar to that of other cephalosporins. Diarrhoea was the most commonly reported adverse event; however, the risk of Clostridium difficile-associated diarrhoea with ceftaroline fosamil appeared to be low. Potential limitations of the drug include the lack of an oral formulation and the requirement for twice-daily administration. Nonetheless, ceftaroline fosamil represents an attractive option (either alone or in combination with other agents) for the initial empirical treatment of patients hospitalized with cSSTIs (including those with suspected MRSA infection) or CAP (PORT risk class III or IV) who require intravenous antimicrobial therapy. As with all antibacterial agents, ceftaroline fosamil should be used in accordance with good antimicrobial stewardship.

Abstract
Foot infections are the most common infectious complication of diabetes. Moderate to severe diabetic foot infections (DFI) are typically polymicrobial with both aerobic and anaerobic organisms. The role of MRSA in these wounds has become an increasing concern. To determine if the addition of avibactam, a novel non-beta-lactam beta-lactamase inhibitor, to ceftaroline would be more active than ceftaroline alone, we tested 316 aerobic pathogens and 154 anaerobic recovered from patients with moderate to severe DFI, and compared ceftaroline with and without avibactam to other agents. Testing on aerobes was done by broth microdilution and by agar dilution for anaerobes, according to CLSI M11-A8, and M7-A8 standards. Ceftaroline-avibactam MIC90 for all Staphylococcus spp. including MRSA was 0.5 μg/mL, and for enterococci was 1 μg/mL. The MIC90s for enteric Gram-negative rods was 0.125 μg/mL. The addition of avibactam to ceftaroline reduced the ceftaroline MICs for 2 strains of resistant Enterobacter spp. and for 1 strain of Morganella. Against anaerobic Gram-positive cocci ceftaroline-avibactam had an MIC90 0.125 μg/mL and for clostridia 1 μg/mL. Avibactam improved ceftaroline's MIC90s for Bacteroides fragilis from >32 to 2 μg/mL and for Prevotella spp. from >32 to 1 μg/mL. Ceftaroline alone demonstrates excellent in vitro activity against most of the aerobes found in moderate to severe DFI. The addition of avibactam provides an increased spectrum of activity including the beta-lactamase producing Prevotella, Bacteroides fragilis and ceftaroline resistant gram-negative enteric organisms.

Abstract
More than 5 million Americans are bitten by animals, usually dogs, annually. Bite patients comprise ∼1% of all patients who visit emergency departments (300,000/year), and approximately 10,000 require hospitalization and intravenous antibiotics. Ceftaroline is the bioactive component of the prodrug ceftaroline fosamil, which is FDA approved for the treatment of acute bacterial skin and skin structure infections (ABSSSIs), including those containing methicillin-resistant Staphylococcus aureus (MRSA). There are no in vitro data about the activity of ceftaroline against Pasteurella multocida subsp. multocida and Pasteurella multocida subsp. septica, other Pasteurella spp., or other bite wound isolates. We therefore studied the in vitro activity of ceftaroline against 243 animal bite isolates. MICs were determined using the broth microdilution method according to CLSI guidelines. Comparator drugs included cefazolin, ceftriaxone, ertapenem, ampicillin-sulbactam, azithromycin, doxycycline, and sulfamethoxazole-trimethoprim (SMX-TMP). Ceftaroline was the most active agent against all 5 Pasteurella species, including P. multocida subsp. multocida and P. multocida subsp. septica, with a maximum MIC of ≤0.008 μg/ml; more active than ceftriaxone and ertapenem (MIC(90)s, ≤0.015 μg/ml); and more active than cefazolin (MIC(90), 0.5 μg/ml) doxycycline (MIC(90), 0.125 μg/ml), azithromycin (MIC(90), 0.5 μg/ml), ampicillin-sulbactam (MIC(90), 0.125 μg/ml), and SMX-TMP (MIC(90), 0.125 μg/ml). Ceftaroline was also very active against all S. aureus isolates (MIC(90), 0.125 μg/ml) and other Staphylococcus and Streptococcus species, with a maximum MIC of 0.125 μg/ml against all bite isolates tested. Ceftaroline has potential clinical utility against infections involving P. multocida, other Pasteurella species, and aerobic Gram-positive isolates, including S. aureus.

Abstract
The growing prevalence of resistant Gram-positive pathogens such as methicillin-resistant Staphylococcus aureus continues to pose a dilemma to clinicians. With strains developing reduced susceptibility to vancomycin, effective and well-tolerated antibiotics to combat these resistant pathogens are needed. Ceftaroline is a new parenteral cephalosporin that has been available in the USA for almost 2 years. Similar to other cephalosporins, it is well tolerated with mostly mild adverse events; however, compared with existing parenteral cephalosporins, ceftaroline has the unique attribute of being bactericidal against resistant Gram-positive aerobes including both hospital- and community-acquired methicillin-resistant S. aureus, S. aureus strains with reduced susceptibility or complete resistance to vancomycin, and resistant Streptococcus pneumoniae including multidrug-resistant strains. Current indications in the USA and Europe include treatment of adults with complicated skin, skin-structure infections and community-acquired pneumonia. This paper will review the properties of ceftaroline, its spectrum of activity, clinical use, safety profile and future role.

Abstract
Ceftaroline fosamil is a cephalosporin antibacterial approved by the US Food and Drug Administration (FDA) for use in the treatment of acute bacterial skin and skin structure infections (ABSSSI) and community-acquired bacterial pneumonia (CABP). After intravenous administration, ceftaroline fosamil is rapidly converted to its bioactive metabolite, ceftaroline. Ceftaroline has broad-spectrum in vitro activity against Gram-positive and Gram-negative bacteria, including contemporary resistant Gram-positive phenotypes, such as methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Streptococcus pneumoniae. Because of its unique spectrum of activity, the Clinical and Laboratory Standards Institute (CLSI) designated ceftaroline as a member of a new subclass of β-lactam antimicrobials, cephalosporins with anti-MRSA activity. The activity of ceftaroline against S. aureus extends to heteroresistant vancomycin-intermediate, vancomycin-intermediate, vancomycin-resistant and daptomycin-nonsusceptible isolates. Ceftaroline has low minimum inhibitory concentrations (MICs) for all tested species of streptococci, and has potent activity against S. pneumoniae isolates with varying degrees of penicillin resistance. The activity of ceftaroline is limited against Enterococcus faecalis and Enterococcus faecium and against anaerobes such as Bacteroides fragilis. The in vitro activity of ceftaroline includes many Gram-negative pathogens, but does not extend to bacteria that produce extended-spectrum β-lactamases, class B metallo-β-lactamases or AmpC cephalosporinases, or to most nonfermentative Gram-negative bacilli. Ceftaroline fosamil has been studied for the treatment of complicated skin and skin structure infections (cSSSI) and community-acquired pneumonia (CAP) in phase III randomized, double-blind, international, multicentre noninferiority clinical trials. Two identical trials (CANVAS 1 and CANVAS 2) compared the efficacy of ceftaroline fosamil with that of vancomycin plus aztreonam in 1378 adults with cSSSI. Results demonstrated that ceftaroline was noninferior to vancomycin plus aztreonam, with 91.6% in the ceftaroline fosamil group (pooled analysis) achieving clinical response compared with 92.7% in the vancomycin plus aztreonam group (difference -1.1%, 95% CI -4.2, 2.0). An additional analysis evaluated clinical cure in a subgroup of patients who met the FDA guidance definition of ABSSSI at treatment day 3. Clinical response, defined as cessation of lesion spread and absence of fever, was 74.0% in the ceftaroline fosamil group compared with 66.2% in the vancomycin plus aztreonam group (treatment difference 7.8%, 95% CI 1.3, 14.0). Clinical efficacy of ceftaroline fosamil in 1240 hospitalized adults with CAP was compared with that of ceftriaxone in two additional phase III trials (FOCUS 1 and FOCUS 2). Of note, because ceftriaxone does not have activity against MRSA, patients with confirmed or suspected MRSA CAP were excluded from the FOCUS trials. Results demonstrated that ceftaroline was noninferior to ceftriaxone, with 84.3% in the ceftaroline fosamil group achieving clinical cure compared with 77.7% in the ceftriaxone group (difference 6.7%, 95% CI 1.6, 11.8). An additional analysis of the trials was conducted in patients with moderate to severe CAP and at least one proven typical bacterial pathogen at baseline (i.e. CABP). Day 4 clinical response rates were 69.5% for ceftaroline and 59.4% for ceftriaxone (difference 10.1%, 95% CI -0.6, 20.6). In the phase III trials, adverse event rates were similar between groups. Overall, ceftaroline is well tolerated, which is consistent with the good safety and tolerability profile of the cephalosporin class. In summary, ceftaroline fosamil is a broad-spectrum parenteral cephalosporin with excellent in vitro activity against resistant Gram-positive pathogens, including MRSA, as well as many common Gram-negative organisms. It is a welcome treatment option for ABSSSI and CABP.

Abstract
INTRODUCTION Bacterial resistance is increasing on a global basis, making treatment options more limited. The development of new agents to meet this threat is a matter of urgency. Ceftaroline fosamil , a member of an advanced cephalosporin class of antimicrobials, is currently approved by the US Food and Drug Administration for use in for acute bacterial skin and skin structure infection (ABSSSI) and community-acquired bacterial pneumonia. Ceftaroline displays activity against Gram-positive and Gram-negative bacteria, including both methicillin-susceptible and resistant Staphylococcus aureus (MRSA), Streptococcus pneumoniae (including penicillin- and ceftriaxone-resistant strains), respiratory pathogens (such as Moraxella catarrhalis and Haemophilus influenzae, including beta-lactamase-producing strains) and limited coverage against Enterobacteriaceae. AREAS COVERED Chemistry, mechanism of action, spectrum of activity, resistance, pharmacokinetics/pharmacodynamics, indications for use, safety and special populations are covered in this review. EXPERT OPINION Ceftaroline's unique activity against MRSA and penicillin- and ceftriaxone-resistant S. pneumoniae strains is due to its high affinity for penicillin binding protein (PBP)-2a and PBP-2x, respectively. In randomized, double-blinded, clinical trials, ceftaroline fosamil was found to be non-inferior to ceftriaxone for the treatment CABP and to vancomycin plus aztreonam for ABSSSI. Substantial differences between the cephalosporins exist. Ceftaroline has unique characteristics that may make it useful in specific clinical circumstances, especially against multi-drug-resistant Gram-positive organisms.

Abstract
BACKGROUND Ceftaroline is a cephalosporin with expanded gram-positive activity recently approved for clinical uses by the US Food and Drug Administration. OBJECTIVE This article provides an overview of the in vitro and in vivo activities, mechanism of action, pharmacologic and pharmacokinetic properties, clinical efficacy, and tolerability of ceftaroline. METHODS Relevant information was identified through a search of PubMed (1990-April 2011), EMBASE (1990-April 2011), International Pharmaceutical Abstracts (1970-April 2011), and Google Scholar using the key words ceftaroline, PPI-0903, PPI-0903M, T-91825, and TAK-599. A review of the reference lists of identified articles, a search of the US Food and Drug Administration Web site, and posters and abstracts from scientific meetings yielded additional publications. RESULTS In vitro, ceftaroline exhibits activity against most aerobic gram-positive isolates, common aerobic gram-negative respiratory pathogens, and some gram-positive anaerobes. The MIC range for most Staphylococcus aureus isolates, including vancomycin-resistant strains was between ≤0.008 and 4 μg/mL. In Phase III studies (CANVAS 1 and CANVAS 2), ceftaroline was found to be noninferior to vancomycin + aztreonam for the treatment of complicated skin and skin-structure infections, with a clinical cure rate of 91.6% among clinically evaluable patients (ceftaroline versus vancomycin + aztreonam: difference, -1.1; 95% CI, -4.2 to 2.0; P = NS). Ceftaroline's efficacy has also been assessed for the treatment of community-acquired pneumonia in 2 Phase III studies (FOCUS 1 and FOCUS 2) and was equivalent to ceftriaxone, with cure rates of 84.3% and 77.7%, respectively, among clinically evaluable patients in the combined analysis (ceftaroline versus ceftriaxone: difference, 6.7; 95% CI, 1.6 to 11.8). The recommended dosage for patients 18 years and older is 600 mg IV every 12 hours. Dosage adjustment is necessary in patients with renal impairment (creatinine clearance ≤50 mL/min). The pharmacokinetic properties of ceftaroline in patients with hepatic impairments are currently unavailable. Ceftaroline appeared to be well tolerated generally. The most frequently (>3%) reported adverse events were nausea, headaches, diarrhea, pruritus, rash, and insomnia; all were usually mild to moderate, self-limiting, and of little clinical significance. CONCLUSIONS Ceftaroline is a cephalosporin with broad gram-positive activity, including Methicillin-resistant S aureus and vancomycin-resistant S aureus. Its gram-negative activity includes common respiratory pathogens and members of the Enterobacteriaceae. Clinical trials have reported that ceftaroline was noninferior to ceftriaxone, and vancomycin + aztreonam for the treatment of community-acquired pneumonia and complicated skin and skin-structure infections, respectively.

Abstract
Ceftaroline is a novel broad-spectrum cephalosporin β-lactam antibiotic with activity against methicillin-resistant Staphylococcus aureus (MRSA) as well as multidrug-resistant Streptococcus pneumoniae among other routine Gram positive and Gram negative organisms. It has been approved by the US Food and Drug Administration for treatment of community-acquired bacterial pneumonia and acute bacterial skin and skin structure infections (ABSSSIs). Ceftaroline is approved for treatment of ABSSSI due to MRSA, however currently there are no data for pneumonia due to MRSA in humans. Herein we review the major clinical trials as well as ceftaroline microbiology, pharmacokinetics, and safety, followed by a look at further directions for investigation of this new agent.

Abstract
OBJECTIVE To review the pharmacology, microbiology, chemistry, in vitro activity, pharmacokinetics, clinical efficacy, safety, dosage, and administration of ceftaroline fosamil (Teflaro, Forest Laboratories, Inc.), a novel parenteral broad-spectrum cephalosporin approved by the Food and Drug Administration (FDA) on October 29, 2010, for the treatment of adults with acute bacterial skin and skin structure infections (ABSSSI) and community-acquired bacterial pneumonia (CABP). DATA SOURCES A search of MEDLINE (1966-July 2011) using the search terms ceftaroline fosamil, ceftaroline, TAK-599, PPI-0903, PPI-0903M, and T-91825 was performed. Supplementary sources included program abstracts from the Interscience Conference on Antimicrobial Agents and Chemotherapy, American Society of Microbiology, European Congress on Clinical Microbiology and Infectious Diseases, and the Infectious Diseases Society of America from 2005 to 2010, as well as information available from the manufacturer's Web site. STUDY SELECTION AND DATA EXTRACTION All English-language articles identified from the data sources were evaluated. In vitro, preclinical, and Phase 1, 2, and 3 clinical trials were included. DATA SYNTHESIS Clinical trials have been conducted evaluating use of ceftaroline for treatment of ABSSSI and CABP. Safety data from Phase 1, 2, and 3 clinical trials suggest that it is well tolerated and has a safety and tolerability profile common to the cephalosporin class. Ceftaroline has excellent in vitro activity against gram-positive pathogens, including methicillin-resistant Staphylococcus aureus (MRSA), which makes it an attractive monotherapy for the treatment of ABSSSI. However, it lacks activity against problem gram-negative bacteria (eg, Pseudomonas spp.), which will likely limit its use for serious health care-associated infections. While its role in treating CABP is supported by excellent in vitro activity against Streptococcus pneumoniae and clinical efficacy data, currently available comparators may offer some advantages over ceftaroline. Finally, data are lacking to assess its role in the treatment of serious infections due to MRSA (eg, pneumonia, bacteremia). CONCLUSIONS These considerations should be part of the formulary review process; however, when considering the significant role MRSA plays in ABSSSI in both the community and hospital settings, we believe that ceftaroline will provide clinicians with a welcome option in addition to currently available anti-MRSA therapies for the treatment of ABSSSI.

Abstract
Cephalosporins have been widely used over the last few decades (often as first-line antibiotic therapy) for numerous infections, owing primarily to their broad spectrum of microbiologic activity and favorable safety profile. Current Infectious Diseases Society of America guidelines identify a third-generation cephalosporin in combination with a macrolide antibiotic as an option for treatment of hospitalized adult patients with community-acquired pneumonia (CAP) outside the intensive care unit setting. Although ceftriaxone is a frequently used agent for CAP, increasing incidence of multidrug-resistant Streptococcus pneumoniae and concerns regarding poor outcomes associated with ineffective therapy have prompted the search for a well-tolerated treatment alternative that is effective against bacteria that can cause CAP. Ceftaroline fosamil, the prodrug of ceftaroline, is a new extended-spectrum cephalosporin that exhibits time-dependant bactericidal activity against numerous Gram-negative and Gram-positive organisms, including methicillin-resistant Staphylococcus aureus and penicillin-resistant S. pneumoniae. Notable exceptions include Pseudomonas spp. and Gram-negative organisms that produce extended-spectrum β-lactamases or carbapenemases. Two large Phase III clinical trials (FOCUS 1 and 2) reported that ceftaroline fosamil was well tolerated, with a clinical cure rate of CAP that was noninferior to that with ceftriaxone in nonintensive care unit adult inpatients with moderately severe (Pneumonia Outcomes Research Team score of III or IV) community-acquired pneumonia.

[PMID: 21402844 PMCID: PMC3101400 DOI: 10.1128/aac.01787-10] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2010] [Revised: 02/13/2011] [Accepted: 03/07/2011] [Indexed: 11/20/2022] Open
Abstract
The in vitro activities of ceftaroline and comparative agents were determined for a collection of the most frequently isolated bacterial pathogens from hospital-associated patients across Canada in 2009 as part of the ongoing CANWARD surveillance study. In total, 4,546 isolates from 15 sentinel Canadian hospital laboratories were tested using the Clinical and Laboratory Standards Institute (CLSI) broth microdilution method. Compared with other cephalosporins, including ceftobiprole, cefepime, and ceftriaxone, ceftaroline exhibited the greatest potency against methicillin-susceptible Staphylococcus aureus (MSSA), with a MIC₉₀ of 0.25 μg/ml. Ceftaroline also demonstrated greater potency than ceftobiprole against community-associated methicillin-resistant S. aureus (MRSA) (MIC₉₀, 0.5 μg/ml) and health care-associated MRSA (MIC₉₀, 1 μg/ml) and was at least 4-fold more active than other cephalosporins against Staphylococcus epidermidis; all isolates of MSSA and MRSA tested were susceptible to ceftaroline (MIC, ≤1 μg/ml). Against streptococci, including Streptococcus pneumoniae, ceftaroline MICs (MIC₉₀, ≤0.03 μg/ml) were comparable to those of ceftobiprole; however, against penicillin-nonsusceptible, macrolide-nonsusceptible, and multidrug-nonsusceptible isolates of S. pneumoniae, ceftaroline demonstrated 2- to 4-fold and 4- to 16-fold more potent activities than those of ceftobiprole and ceftriaxone, respectively. All isolates of S. pneumoniae tested were susceptible to ceftaroline (MIC, ≤0.25 μg/ml). Among Gram-negative isolates, ceftaroline demonstrated potent activity (MIC₉₀, ≤0.5 μg/ml) against Escherichia coli (92.2% of isolates were susceptible), Klebsiella pneumoniae (94.1% of isolates were susceptible), Proteus mirabilis (97.7% of isolates were susceptible), and Haemophilus influenzae (100% of isolates were susceptible). Ceftaroline demonstrated less potent activity (MIC₉₀, ≥4 μg/ml) against Enterobacter spp., Acinetobacter baumannii, Pseudomonas aeruginosa, Klebsiella oxytoca, Serratia marcescens, and Stenotrophomonas maltophilia. Overall, ceftaroline demonstrated potent in vitro activity against a recent collection of the most frequently encountered Gram-positive and Gram-negative isolates from patients attending hospitals across Canada in 2009.

Abstract
Ceftaroline (PPI 0903, formerly TAK-599), the active metabolite of a N-phosphono prodrug, ceftaroline fosamil, has been approved by the US Food and Drug Administration for the treatment of acute bacterial skin and skin structure infections and community-acquired bacterial pneumonia. This antimicrobial agent binds to penicillin binding proteins (PBP) inhibiting cell wall synthesis and has a high affinity for PBP2a, which is associated with methicillin resistance. Ceftaroline is consistently active against multidrug-resistant Streptococcus pneumoniae and Staphylococcus aureus, including methicillin-resistant, vancomycin-intermediate, linezolid-resistant, and daptomycin-nonsusceptible strains. It possesses variable activity against Enterobacteriaceae and good activity against oral anaerobes. The drug is usually administrated intravenously at 600 mg every 12 h. Ceftaroline has low protein binding and is excreted by the kidneys and thus requires dose adjustments in individuals with renal failure. Clinical trials have demonstrated noninferiority when compared with vancomycin in the treatment of acute bacterial skin and skin structure infections and noninferiority when compared with ceftriaxone in the treatment of community-acquired bacterial pneumonia. Ceftaroline demonstrated a safety profile similar to that of comparator drugs in clinical trials.

Abstract
OBJECTIVES To document the spectrum of activity of ceftaroline, the active form of the prodrug, ceftaroline fosamil, a new cephalosporin with anti-methicillin-resistant staphylococcal activity, against a surveillance collection of clinical isolates obtained from the USA and Europe during 2008-09. METHODS A selected group of species associated with community-acquired pneumonia (CAP; 6496 of 17 326 monitored strains) were tested for susceptibility in a central laboratory using CLSI broth microdilution methods. Organisms were sampled from 55 medical centres, 27 in the USA and 28 (12 countries) in Europe. Ceftaroline and comparator agents were tested and interpretations of MIC endpoints made by applying current CLSI (2010) and EUCAST (2010) breakpoint criteria. RESULTS Against 1340 Streptococcus pneumoniae, ceftaroline inhibited all isolates at ≤0.5 mg/L (MIC(50/90), ≤0.008/0.12 mg/L) and was 8-fold more active than ceftriaxone (MIC(90), 1 mg/L; only 79.2% coverage at EUCAST breakpoint). Haemophilus influenzae (n = 584; MIC(50/90), ≤0.008/0.015 mg/L), Moraxella catarrhalis (n = 377; MIC(50/90), 0.03-0.06/0.12 mg/L) and Staphylococcus aureus (n = 590; MIC(50/90), 0.5/1 mg/L) were very susceptible to ceftaroline, regardless of β-lactamase production or multidrug resistance (MDR) patterns. The potency of ceftaroline against three species of Enterobacteriaceae (Escherichia coli, Klebsiella pneumoniae and Enterobacter cloacae) was similar to that of ceftriaxone, ceftazidime and piperacillin/tazobactam. Only modest differences in rates of ceftaroline susceptibility (breakpoint ≤2 mg/L) were noted with extended-spectrum β-lactamase-negative Enterobacteriaceae strains between the USA and Europe (97.9% versus 97.0% for E. coli). Ceftaroline, like ceftriaxone, was not active against ceftazidime-resistant E. coli (10.2%-26.2% susceptible at ≤2 mg/L) or K. pneumoniae (5.3%-11.2%). CONCLUSIONS The ceftaroline surveillance for 2008-09 (USA and Europe) documented low MIC(50/90) values for S. aureus isolates at 0.5/1 and 0.25/1 mg/L, respectively. More importantly, ceftaroline MIC(90) results for S. pneumoniae (0.12 mg/L), H. influenzae (0.015 mg/L) and M. catarrhalis (0.12 mg/L) were very low, all MICs being ≤0.5 mg/L. Ceftaroline exhibited promising high potency and wide coverage against Gram-positive and -negative pathogens known to cause CAP, especially isolates of MDR pneumococci and methicillin-resistant S. aureus.

Abstract
Microbial resistance has reached alarming levels, threatening to outpace the ability to counter with more potent antimicrobial agents. In particular, methicillin-resistant Staphylococcus aureus (MRSA) has become a leading cause of skin and soft-tissue infections and PVL-positive strains have been associated with necrotizing pneumonia. Increasing reports of growing resistance to glycopeptides have been noted, further limiting the efficacy of standard antibiotics, such as vancomycin. Ceftaroline is a novel fifth-generation cephalosporin, which exhibits broad-spectrum activity against Gram-positive bacteria, including MRSA and extensively-resistant strains, such as vancomycin-intermediate S. aureus (VISA), heteroresistant VISA (hVISA), and vancomycin-resistant S. aureus (VRSA). In addition to being an exciting new agent in the anti-MRSA armamentarium, ceftaroline provides efficacy against many respiratory pathogens including Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Ceftaroline (600 mg intravenously every 12 hours) has been shown effective in phase III studies in the treatment of complicated skin and soft tissue infections and community-acquired pneumonia. To date, this unique antibiotic exhibits a low propensity for inducing resistance and has a good safety profile, although further post-marketing data and clinical experience are needed. In summary, ceftaroline provides an additional option for the management of complex multidrug resistant infections, including MRSA.

Abstract
Several studies have shown that the rates of resistant Gram-positive pathogens, such as methicillin-resistant Staphylococcus aureus, vancomycin-intermediate S. aureus (VISA), hetero-VISA, and penicillin-resistant Streptococcus pneumoniae have witnessed a substantial global increase. Ceftaroline fosamil is the prodrug form of ceftaroline, a new cephalosporin active against resistant Gram-positive pathogens and common Gram-negative organisms that do not produce extended-spectrum-β-lactamases and do not express AmpC. Ceftaroline fosamil was found to be effective and well-tolerated for the treatment of complicated skin and skin-structure infections and community-acquired bacterial pneumonia compared with standard therapy. The drug has recently been granted US FDA approval for both indications.
