KENILWORTH, N.J.--(BUSINESS WIRE)--Merck (NYSE: MRK), known as MSD outside the United States and Canada, today announced that researchers will provide 40 scientific data presentations on the company’s established and investigational infectious disease medicines and vaccines at ID Week 2017 in San Diego from Oct. 4-8. Antimicrobial research remains an important area of focus at Merck, with ongoing clinical studies in antibiotic, antiviral and antifungal medicines; adult and pediatric vaccines; and medicines for HIV and HCV.
“At Merck, we remain deeply committed to developing medicines and vaccines that help to prevent and treat serious infectious diseases to help address some of the most pressing public health threats in the world today,” said Dr. Joan Butterton, executive director and section head for antibacterials/CMV, infectious disease clinical research, Merck Research Laboratories. “We also continue to collaborate with researchers, clinicians and other stakeholders worldwide to provide important surveillance data and to advocate for antimicrobial stewardship.”
Presentations at ID Week 2017 will include new data analyses from the pivotal Phase 3 clinical study of letermovir, Merck’s investigational antiviral medicine for prophylaxis of cytomegalovirus (CMV) infection or disease in adult CMV-seropositive recipients of an allogeneic hematopoietic stem cell transplant (HSCT).
Results from a Phase 3 study of V212, Merck’s investigational vaccine for herpes zoster, in autologous HSCT recipients will be discussed during an oral presentation at the meeting.
Researchers also will present real-world susceptibility and clinical use data, as well as data on the in vitro activity of ZERBAXA. ZERBAXA® 1.5 g (ceftolozane 1 g and tazobactam 0.5 g) is indicated for the treatment of adults with complicated urinary tract infections (cUTI), including pyelonephritis, and in combination with metronidazole, complicated intra-abdominal infections (cIAI) caused by designated susceptible Gram-negative and Gram-positive bacteria.
Other studies to be presented include in vitro data collected as part of the SMART (Study for Monitoring Antimicrobial Resistance Trends) surveillance program. SMART was initiated by Merck in 2002 to monitor the in vitro susceptibility of clinical isolates to several commonly used antibiotics in different regions of the world to monitor changing trends in antibiotic susceptibility. Bacterial samples have been collected and characterized from patients with intra-abdominal, urinary tract and lower-respiratory tract infections.

Merck’s commitment to infectious diseases
For more than 80 years, Merck has contributed to the discovery and development of novel medicines and vaccines to combat infectious diseases. In addition to a combined portfolio of antibiotic and antifungal medicines, vaccines, and medicines for HIV and HCV, Merck has multiple programs that span discovery through late-stage development. Merck currently has eight compounds in Phase 2/Phase 3 clinical trials for the potential treatment or prevention of infectious diseases.
About ZERBAXA (ceftolozane and tazobactam)
ZERBAXA is an antibacterial combination product for intravenous infusion consisting of the cephalosporin antibacterial drug ceftolozane sulfate and the beta-lactamase inhibitor tazobactam sodium.
ZERBAXA is approved in the United States and is indicated in adult patients for the treatment of complicated urinary tract infections (cUTI), including pyelonephritis, caused by the following Gram-negative microorganisms: Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Pseudomonas aeruginosa. ZERBAXA used in combination with metronidazole is indicated in adult patients for the treatment of complicated intra-abdominal infections (cIAI) caused by the following Gram-negative and Gram-positive microorganisms: Enterobacter cloacae, Escherichia coli, Klebsiella oxytoca, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Bacteroides fragilis, Streptococcus anginosus, Streptococcus constellatus, and Streptococcus salivarius.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of ZERBAXA and other antibacterial drugs, ZERBAXA should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
Important Safety Information about ZERBAXA (ceftolozane and tazobactam)
Patients with renal impairment: Decreased efficacy of ZERBAXA has been observed in patients with baseline creatinine clearance (CrCl) of 30 to ≤50 mL/min. In a clinical trial, patients with cIAIs with CrCl >50 mL/min had a clinical cure rate of 85.2% when treated with ZERBAXA (ceftolozane and tazobactam) plus metronidazole vs. 87.9% when treated with meropenem. In the same trial, patients with CrCl 30 to ≤50 mL/min had a clinical cure rate of 47.8% when treated with ZERBAXA plus metronidazole vs. 69.2% when treated with meropenem. A similar trend was also seen in the cUTI trial. Monitor CrCl at least daily in patients with changing renal function and adjust the dose of ZERBAXA accordingly.
Hypersensitivity: ZERBAXA is contraindicated in patients with known serious hypersensitivity to ceftolozane/tazobactam, piperacillin/tazobactam, or other members of the beta-lactam class. Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients receiving beta-lactam antibacterials. Before initiating therapy with ZERBAXA, make careful inquiry about previous hypersensitivity reactions to cephalosporins, penicillins, or other beta-lactams. If an anaphylactic reaction to ZERBAXA occurs, discontinue use and institute appropriate therapy.
Clostridium difficile–associated diarrhea (CDAD), ranging from mild diarrhea to fatal colitis, has been reported with nearly all systemic antibacterial agents, including ZERBAXA. Careful medical history is necessary because CDAD has been reported to occur more than two months after the administration of antibacterial agents. If CDAD is confirmed, antibacterial use not directed against C. difficile should be discontinued, if possible.
Development of drug-resistant bacteria: Prescribing ZERBAXA in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.
Adverse reactions: The most common adverse reactions occurring in ≥5% of patients were headache (5.8%) in the cUTI trial, and nausea (7.9%), diarrhea (6.2%) and pyrexia (5.6%) in the cIAI trial.
