Publication reaffirms the proven efficacy and safety of rezafungin dosed once-weekly versus a current standard of care echinocandin dosed once-daily

PARSIPPANY, NJ, and SAN DIEGO, CA — Dec 5, 2023 — Melinta Therapeutics, LLC and Cidara Therapeutics, Inc. (NASDAQ: CDTX) today announced the peer-reviewed publication of pooled data from two completed global clinical trials evaluating REZZAYO^® (rezafungin for injection) for the treatment of candidemia and invasive candidiasis. The article, “Efficacy and safety of rezafungin and caspofungin in candidemia and invasive candidiasis: pooled data from two prospective randomised controlled trials,” published in The Lancet Infectious Diseases, reports on pooled data analyses of the pivotal ReSTORE Phase 3 randomized controlled clinical trial, which demonstrated the non-inferiority of REZZAYO as compared to caspofungin for all-cause mortality, and the STRIVE Phase 2 randomized controlled trial, which provided safety and supportive efficacy data for REZZAYO. The pooled analyses in the article further support the non-inferiority of rezafungin versus caspofungin for all-cause mortality and with similar safety profiles and provide additional evidence for potential early treatment benefits. 

Christine Ann Miller, president and chief executive officer of Melinta Therapeutics, said, “We are very pleased with the publication of the pooled data from two completed clinical trials, the ReSTORE Phase 3 trial and the Phase 2 STRIVE trial, in Lancet ID, which, combined, continue to demonstrate a consistent efficacy and safety profile of REZZAYO as compared to caspofungin. These findings are of clinical importance given the ongoing morbidity and mortality caused by candidemia and invasive candidiasis. Since the approval of REZZAYO, Melinta has been leveraging our commercial infrastructure and experience in marketing infectious disease products, particularly within the hospital and acute care settings, to make REZZAYO available to healthcare providers and their patients suffering with candidemia and invasive candidiasis.”

Taylor Sandison, MD, MPH, chief medical officer at Cidara Therapeutics, added, “The continued clinical success of REZZAYO across global populations reinforces its potential as a therapeutic option for patients suffering from candidemia and invasive candidiasis.”

The ReSTORE pivotal Phase 3 trial demonstrated that REZZAYO met the primary endpoint for the U.S. Food and Drug Administration (FDA) New Drug Application (NDA) submission of all-cause mortality at Day 30, and also met the primary endpoint for the European Medicines Agency (EMA) Marketing Authorization Application (MAA) submission of global cure at Day 14. The STRIVE Phase 2 study provided safety and supportive efficacy data on REZZAYO.

In both studies, researchers evaluated one 400 milligram (mg) dose of REZZAYO for the first week followed by 200 mg of REZZAYO dosed once weekly for up to four weeks in total. REZZAYO was generally well tolerated and had a similar safety profile to caspofungin.

On March 22, 2023, the FDA approved REZZAYO for the treatment of candidemia and invasive candidiasis in adults with limited or no alternative treatment options. REZZAYO is the first new treatment option approved for patients with candidemia and invasive candidiasis in over fifteen years. Based on Qualified Infectious Disease Product (QIDP) designation, REZZAYO was approved under Priority Review. The Centers for Medicare & Medicaid Services (CMS) issued a permanent product-specific J-Code (J0349, Injection, rezafungin, 1 mg) for REZZAYO injection effective October 1, 2023. CMS also granted a new technology add-on payment (NTAP) for REZZAYO for eligible participating hospitals when Medicare patients are treated in the inpatient acute care hospital setting.

Last year, Melinta announced that it had acquired the exclusive rights to commercialize rezafungin in the U.S. from Cidara. Cidara retains the rights to rezafungin in Japan and has licensed the commercial rights to Melinta Therapeutics in the U.S. and Mundipharma in all other geographies. The EMA accepted the MAA for rezafungin in August 2022, and it is currently under review.  In October, the EMA Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion for rezafungin (rezafungin acetate) for the treatment of invasive candidiasis in adults.

About REZZAYO^® (rezafungin for injection)

REZZAYO (rezafungin for injection) is a novel once weekly echinocandin approved in the United States for the treatment of candidemia and invasive candidiasis in adults. REZZAYO is currently being studied for the prevention of invasive fungal diseases in adults undergoing allogeneic blood and marrow transplantation.

Parsippany, N.J., and Malvern, PA — November 9, 2023 — Melinta Therapeutics LLC (“Melinta”) and Venatorx Pharmaceuticals, Inc. (“Venatorx”), today announced that they have entered into a License Agreement to facilitate a strategic partnership in the U.S. to commercialize cefepime-taniborbactam, a beta-lactam / beta-lactamase inhibitor (BL/BLI) combination antibiotic being developed for the treatment of complicated urinary tract infections (cUTI) and hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP) in adults.

The partnership follows Venatorx’s submission of a New Drug Application (NDA) for cefepime-taniborbactam for the treatment of cUTI including pyelonephritis, in adults. Venatorx has been assigned a Prescription Drug User Fee Act (PDUFA) target action date for February 22, 2024. The U.S. Food and Drug Administration (FDA) granted cefepime-taniborbactam Qualified Infectious Disease Product (QIDP) and Fast Track designations for both the cUTI and HABP/VABP indications.

Cefepime-taniborbactam was developed to address the need for new, novel antibiotics to battle increasing gram-negative resistance, which is especially critical for high-risk patients. Due to its broad spectrum of in vitro activity against key, common pathogens with established and rapidly increasing mechanisms of carbapenem resistance, such as serine- and metallo-beta-lactamases, and the positive results demonstrated in the CERTAIN-1, cUTI study, cefepime-taniborbactam, if approved, will address a critical unmet need. CERTAIN-1 was a randomized, double-blind, active-controlled Phase 3 trial comparing cefepime-taniborbactam to meropenem in hospitalized adults with cUTI including acute pyelonephritis (AP). Cefepime-taniborbactam has also demonstrated in vitro activity against CDC Urgent and Serious Threat Pathogens multidrug-resistant Pseudomonas aeruginosa, carbapenem-resistant Enterobacterales, and Extended Spectrum Beta-lactamase-producing (ESBL) Enterobacterales.

“The addition of cefepime-taniborbactam accelerates our long-term growth strategy, and if approved, would expand and complement our existing portfolio, and provide clinicians with another option in the fight against the growing crisis of antimicrobial resistance,” said Christine Ann Miller, President and Chief Executive Officer, Melinta Therapeutics. “Importantly, this partnership supports Melinta’s mission of providing innovative therapies to people impacted by acute and life-threatening illnesses.” Miller added, “While building upon our demonstrated ability to commercialize products in the hospital market, our partnership will also provide a strong foundation for getting this important medicine into the hands of healthcare providers, and ultimately to patients across the U.S.”

“The progression of cefepime-taniborbactam from invention through clinical trials to FDA review is a source of enormous pride to the Venatorx team. With its U.S.  commercial infrastructure and significant experience in commercializing antibiotics, Melinta is ideally positioned to bring this agent to patients in the U.S.,” said Christopher J. Burns, Ph.D., Chief Executive Officer of Venatorx. “This partnership will allow Venatorx to continue advancing all of the R&D and Regulatory elements of its infectious diseases portfolio including its U.S. Government contractual commitments.”

Funding Partners and Collaborators for cefepime-taniborbactam

Development of cefepime-taniborbactam began with federal funds from the National Institute of Allergy and Infectious Diseases, National Institutes of Health, Department of Health and Human Services under contract number HHSN272201300019C, and Wellcome Trust under award number 360G-Wellcome-101999/Z/13/Z, and continues with federal funds from the Biomedical Advanced Research and Development Authority, Administration for Strategic Preparedness and Response, Department of Health and Human Services under contract numbers HHSO100201900007C and 75A50122C00080.

In September 2018, Venatorx entered into an exclusive license agreement with Everest Medicines to support the development, registration, and commercialization of cefepime-taniborbactam in People’s Republic of China, Macau, Hong Kong, Taiwan, South Korea, and select countries in Southeast Asia (the “Territory”).

In April 2020, Venatorx and GARDP announced a collaboration to accelerate the development of, and access to, cefepime-taniborbactam for adult and pediatric populations. Venatorx has granted GARDP exclusive rights to distribute and sub-distribute cefepime-taniborbactam, once it is approved for clinical use, in low- and lower middle-income countries.

About Cefepime-Taniborbactam
Cefepime-taniborbactam is an investigational intravenous (IV) beta-lactam/beta-lactamase inhibitor (BL/BLI) antibiotic combination being developed for the treatment of complicated urinary tract infections (cUTIs), including pyelonephritis, and hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP). Cefepime-taniborbactam was accepted for review by the U.S. FDA for cUTI, including pyelonephritis with a PDUFA date of February 22, 2024.

Cefepime, a fourth-generation cephalosporin, is a widely used beta-lactam (BL) antibiotic with more than two decades of proven safety and clinical utility against susceptible gram-negative and gram-positive bacteria. Taniborbactam is a beta-lactamase inhibitor (BLI) that, in combination with cefepime, is being studied as a potential treatment option for patients with serious bacterial infections caused by antibiotic resistant gram-negative bacteria, most notably Extended Spectrum Beta-lactamase (ESBL)-expressing Enterobacterales, carbapenem-resistant Enterobacterales (CRE), and multidrug-resistant (MDR) Pseudomonas aeruginosa (MDR-PA), which can include carbapenem-resistant P. aeruginosa (CRPA).

Cefepime-taniborbactam has been granted Qualified Infectious Disease Product (QIDP) and Fast Track designations by the U.S. Food and Drug Administration (FDA). Fast Track designation is designed to facilitate the development, and to expedite the review of drugs to treat serious conditions that do not have sufficient treatment options. QIDP designation provides certain incentives for the development of new antibiotics, including priority review, as well as a five-year regulatory exclusivity extension. QIDP was authorized under the Generating Antibiotic Incentives Now (GAIN) Act of 2012, as part of the FDA Safety and Innovation Act, to underscore the urgency in development of new antibiotics.

About Gram-Negative Infections and Antimicrobial Resistance (AMR)
In a recent report on AMR, the U.S. Centers for Disease Control and Prevention (CDC) reported rates of resistance have increased significantly in the U.S. among bacterial pathogens including those commonly causing cUTI, pyelonephritis, and bacteremia. The CDC also cited that there are more than 2.8 million AMR infections annually in the U.S., which are directly related to more than 35,000 deaths.^[1]

Between 2014 and 2019, an analysis of U.S. UTI patients determined that 4.4% of cases were carbapenem resistant (CR) and 24.5% of U.S. UTI patients were bacteremic with 1.7% of cases caused by a CR pathogen. Patients with CR infections had a significantly longer hospital length of stay (LOS), were less likely to be discharged home, had a higher readmission rate, and had greater LOS-associated charges than patients with carbapenem-susceptible infections. Additionally, patients with bacteremia (urosepsis) due to CR pathogens had a significantly higher rate of mortality than those with carbapenem susceptible pathogens.^[2]

Gram-negative bacteria have multiple AMR mechanisms that continue to adapt in response to increases in antibiotic usage. Carbapenems are broad-spectrum antibiotics that have been widely used to treat infections caused by multidrug-resistant gram-negative bacteria, including Enterobacterales. With the increased global use of carbapenems, CRE have emerged, which have limited treatment options and are associated with increased morbidity and mortality. Resistance to carbapenems among Enterobacterales is primarily achieved by production of carbapenemases, which are enzymes capable of hydrolyzing carbapenem antibiotics and most other beta-lactams and fall into two distinct families: serine beta-lactamases and metallo-beta-lactamases (MBLs). Klebsiella pneumoniae carbapenemase (KPC), a class-A serine beta-lactamase, is one of the most prevalent carbapenemases, and New Delhi MBL (NDM) and Verona Integron-encoded MBL (VIM) are common variants of MBLs identified in gram-negative infections due to Enterobacterales and P. aeruginosa. According to an IHMA surveillance study in 2018-2019 and a JMI U.S. Surveillance study from 2021, MBLs were the most commonly identified carbapenem resistance mechanism globally among Enterobacterales isolates, with ~16 to 18% of U.S. CRE isolates carrying MBLs.^[3,4]

While CRPA is also increasing in some geographies due to emergence of MBLs, MDR-PA, which may exhibit resistance to carbapenems, represents an increasing challenge for clinicians and their patients in the U.S. and globally due to the paucity of treatment options for this primarily hospital-associated pathogen. Especially outside the U.S., CRPA may carry carbapenemases including MBLs (i.e., VIM); however, non-carbapenemase resistance mechanisms (i.e., efflux pumps, porins) also contribute to the growing global resistance of MDR-PA and CRPA.^[5]

If AMR infections continue on this trajectory, it has been projected that an estimated 10 million people will die per year of resistant infections by 2050—a number that surpasses the projected annual number of deaths (8.2 million) caused by cancer—and the cumulative cost to the global economy could be as high as U.S. $100 trillion.^[6] In the U.S., estimates have reached as high as U.S. $20 billion in excess direct healthcare costs, with an additional U.S. $35 billion associated with lost productivity.^[7] By 2050, the world is at risk of losing up to 3.8% of its annual gross domestic product with an annual shortfall of up to U.S. $3.4 trillion by 2030, a figure on par with losses attributable to the 2008 global financial crisis.^[8]

The Infectious Disease Society of America (IDSA) maintains updated guidance on the Treatment of Antimicrobial Resistant Gram-Negative Infections online at https://www.idsociety.org/practice-guideline/amr-guidance/.^[9] For those patients who do not respond to current treatment, new antibiotic therapies are needed to combat AMR.

About Complicated Urinary Tract Infections
Complicated UTIs, which include pyelonephritis, are defined as urinary tract infections ascending from the bladder accompanied by local and systemic signs and symptoms, including fever, chills, malaise, flank pain, back pain, and/or costovertebral angle pain or tenderness, that usually occur in the presence of a functional or anatomical abnormality of the urinary tract or in the presence of catheterization. Bacteremia can arise secondary to infections like cUTI and can result in substantial morbidity and mortality. ^[1] Annually in U.S., it is estimated that more than 3 million cUTI patients will be diagnosed and require antibiotic therapy leading to over $6 billion in annualized 30-day costs.^[10]

REZZAYO receives product-specific J-Code and is granted NTAP

PARSIPPANY, N.J., October 2, 2023 – Melinta Therapeutics (Melinta), a commercial-stage company providing innovative therapies for acute and life-threatening illnesses, today announced expanded reimbursement and access for REZZAYO™ (rezafungin for injection). REZZAYO, the first new treatment option approved for adult patients with candidemia and invasive candidiasis in over a decade, has been commercially available in the U.S. since July. 

The Centers for Medicare & Medicaid Services (CMS) issued a permanent product-specific J-Code (J0349, Injection, rezafungin, 1 mg) for REZZAYO injection effective October 1, 2023. CMS also granted a new technology add-on payment (NTAP) for REZZAYO for eligible participating hospitals when Medicare patients are treated in the inpatient acute care hospital setting.

“We are very excited to share the news of the issuance of the J-Code and the NTAP for REZZAYO,” said Christine Ann Miller, Melinta President and CEO. “These two important milestones will help facilitate access to this innovative treatment option in both inpatient and outpatient settings. For Melinta, this is a significant step toward realizing our vision that all patients who need our therapies will receive them.”

A permanent J-Code plays a pivotal role in establishing reimbursement for medical products and services, offering a standardized way to identify the drug across various payers. The unique J-Code can be used for REZZAYO in all outpatient treatment settings. The NTAP, in turn, will provide eligible, participating hospitals with an incremental payment for REZZAYO in addition to the standard Medicare Severity Diagnostic Related Group (MS-DRG) reimbursement for inpatient Medicare cases beginning October 1, 2023. Under NTAP, this additional payment is the lesser of 75% of the costs of REZZAYO, or 75% of the amount by which the costs of the qualifying case exceed the MS-DRG payment, up to a maximum payment of $4,387.50 for a patient treated with REZZAYO per qualifying case.

REZZAYO was granted Qualified Infectious Disease Product (QIDP) designation and was approved by the U.S. Food and Drug Administration under Priority Review on March 22, 2023.  Last year, Melinta acquired the exclusive rights to commercialize REZZAYO in the U.S. from Cidara Therapeutics.  Once-weekly REZZAYO has been available by prescription since July 31, 2023. 

While echinocandins have been available since the early 2000’s, their use has been primarily limited to the hospital inpatient setting due to their requirement of daily IV infusions.  In contrast, REZZAYO is administered as a once-weekly infusion, which may allow appropriate patients to leave the hospital sooner to continue their treatment at home, potentially reducing the burden on patients and the healthcare system. 

“REZZAYO offers a needed option for physicians, and those patients who may be able to transition out of the hospital sooner. The J-Code and NTAP will support broader access to this innovative treatment for patients suffering from invasive Candida infections,” said John Harlow, Melinta’s Chief Commercial Officer. “This is another opportunity for Melinta to deliver on our mission to provide innovative therapies to people impacted by acute and life-threatening illnesses.”

New Treatment for Candidemia and Invasive Candidiasis Now Available in the U.S

PARSIPPANY, NJ, July 31, 2023 –Melinta Therapeutics, LLC today announced the availability of REZZAYO™ (rezafungin for injection), for the treatment of candidemia and invasive candidiasis in adults with limited or no alternative treatment options. REZZAYO is the first new treatment option approved for patients with candidemia and invasive candidiasis in over a decade. Based on Qualified Infectious Disease Product (QIDP) designation, REZZAYO was approved under Priority Review.  

While echinocandins have been available since the early 2000’s, their use has been primarily limited to the hospital in-patient setting due to their requirement of daily IV infusions.  In contrast, REZZAYO is administered as a once weekly infusion, creating the opportunity for appropriate patients to leave the hospital sooner to continue their treatment at home, potentially reducing the burden on patients and the healthcare system. 

John Harlow, Chief Commercial Officer for Melinta Therapeutics said, “Making REZZAYO available in the U.S. is another way Melinta will leverage our expansive commercial infrastructure and experience launching products and therapies into acute care environments with the ultimate goal of better patient care and outcomes.”   

Last year, Melinta announced that it had acquired the exclusive rights to commercialize REZZAYO in the U.S. from Cidara Therapeutics.  Once-weekly REZZAYO is available by prescription beginning July 31, 2023.    

Harlow added, “The availability of REZZAYO, the first new treatment of its kind in over a decade, is a major step forward in offering healthcare providers a way to simplify and treat patients suffering from invasive Candida infections. It’s a much-needed option for physicians, and those patients who may be able to transition out of the hospital sooner.”     

About REZZAYO™ (rezafungin for injection)

Parsippany, NJ – Melinta Therapeutics, LLC (Melinta), a commercial-stage company providing innovative therapies for acute and life-threatening illnesses, announced today a partnership with the Biomedical Advanced Research and Development Authority (BARDA) to advance two antibiotics currently FDA-approved for adults, BAXDELA® (delafloxacin) and VABOMERE® (meropenem and vaborbactam), for use in pediatrics. In addition, Melinta and BARDA will partner on the development of BAXDELA® against biothreat pathogens. Under this contract, BARDA has awarded $20.5M for the base period, with the potential of additional funding of $121.4M, amounting to total funding up to $141.9M if all options are exercised. With this BARDA funding, Melinta aims to submit four supplemental New Drug Applications (sNDAs) for these new indications.

BARDA is part of the U.S. Department of Health and Human Services’ Administration for Strategic Preparedness and Response. This partnership may enable BAXDELA® and VABOMERE® to be integrated into national preparedness efforts as well as pediatric care for multi−drug-resistant bacterial infections, enhancing sustained availability of the products, increasing end-user familiarity, and striving for availability for the US pediatric population.

“I am thrilled and honored that BARDA and Melinta have agreed to partner for this important research marking a significant milestone in our journey toward becoming legendary for providing innovative therapies to people impacted by acute and life-threatening illnesses,” said Christine Miller, Melinta President and CEO. “This contract fuels our excitement to explore expanded applications of BAXDELA® and VABOMERE® through innovative research. We are poised to make a lasting impact in healthcare, unlocking new avenues for patient care and addressing unmet needs. We will drive progress and redefine what is possible, paving the way for a healthier future.”

BAXDELA® (delafloxacin) is a novel fluoroquinolone (FQ), approved for adults in IV and oral tablet formulations to treat acute bacterial skin and skin structure infection (ABSSSI) and community-acquired bacterial pneumonia (CABP). CABP remains a leading cause of pediatric hospitalization and mortality in the US, with the highest incidence and morbidity in children under 2 years of age. The partnership with BARDA will support the BAXDELA® pediatric development plan to extend the adult CABP indication to children aged 2 months to less than 18 years.

In addition, Melinta aims to advance BAXDELA® as a potential treatment option against biothreat pathogens for both adults and children.  Given its broad spectrum of activity and availability in both IV and oral formulations, BAXDELA® can provide flexibility for use following a biothreat public health emergency, in varied care settings and across spectrums of disease severity.

VABOMERE® is an approved combination of the carbapenem, meropenem, and the novel ß-lactamase inhibitor (BLI), vaborbactam. VABOMERE® was specifically designed to address gram-negative bacteria that produce beta-lactamase enzymes, including strains producing the Klebsiella pneumoniae carbapenemase (KPC) enzyme, the predominant form of carbapenem-resistant Enterobacterales (CRE) in the US. The CDC (Centers for Disease Control) classifies CRE as an “urgent” threat because there are few alternative antibiotics to treat CRE-infections. The VABOMERE® pediatric development plan will support the filing of sNDAs to extend the adult cUTI indication to children aged 3 months to less than 18 years and target the indication of late onset neonatal sepsis in children aged less than 90 days.

 

“The ability to partner with BARDA on these important programs is exactly the type of work that brought me to Melinta and what excites me about the work we do,” said Douglas Girgenti, MD, VP, Head of Development and Clinical Operations, Melinta.  “Pediatric clinical development of BAXDELA® and VABOMERE® will help inform drug safety and tolerability as well as determine optimal antibiotic dosing, with the ultimate goal of enabling use in pediatric cases and expanding the arsenal of healthcare providers in their fight to save lives. The potential addition of BAXDELA® to the biodefense armamentarium will likewise provide a much-needed option for public health emergencies in both children and adults.”

 

This project has been funded in whole or in part with federal funds from the Department of Health and Human Services; Administration for Strategic Preparedness and Response; Biomedical Advanced Research and Development Authority, under contract number 75A50123C00022.

IMPORTANT SAFETY INFORMATION:

WARNING: SERIOUS ADVERSE REACTIONS INCLUDING TENDINITIS, TENDON RUPTURE, PERIPHERAL NEUROPATHY, CENTRAL NERVOUS SYSTEM EFFECTS, and EXACERBATION OF MYASTHENIA GRAVIS

Contraindications

BAXDELA® is contraindicated in patients with known hypersensitivity to BAXDELA® or other fluoroquinolones.

Warnings and Precautions

Fluoroquinolones have been associated with disabling and potentially irreversible serious adverse reactions. Avoid use in patients who have experienced any of the following serious adverse reactions. If these reactions occur in patients receiving BAXDELA®, discontinue BAXDELA® immediately and institute appropriate treatment:

• Tendinitis, tendon rupture, with increased risk in elderly, patients taking corticosteroids and in patients with organ transplants
• Peripheral neuropathy, such as pain, burning, tingling, numbness, and/or weakness or other alterations of sensation in touch and/or motor strength
• Central nervous system adverse reactions such as seizures, increased intracranial pressure, dizziness, and tremors
• Exacerbation of myasthenia gravis, including death and requirement for ventilator

Fluoroquinolones, including BAXDELA®, have been associated with an increased risk of psychiatric adverse reactions, including: toxic psychosis; hallucinations, or paranoia; depression, or suicidal thoughts or acts; delirium, disorientation, confusion, or disturbances in attention; anxiety, agitation, or nervousness; insomnia or nightmares; memory impairment. These adverse reactions may occur following the first dose.

Hypersensitivity reactions have been reported in patients receiving fluoroquinolones, including BAXDELA®. Reactions can be serious and occasionally fatal (anaphylactic). Discontinue BAXDELA® at the first sign of hypersensitivity.

Clostridium difficile-associated diarrhea has been reported with nearly all systemic antibacterial agents, including BAXDELA®, with severity ranging from mild diarrhea to fatal colitis. Evaluate if diarrhea occurs.

Fluoroquinolones have been associated with an increased risk of aortic aneurysm and dissection, especially in elderly patients. In patients with a known aortic aneurysm or patients who are at greater risk for aortic aneurysms, reserve BAXDELA® for use only when there are no alternative antibacterial treatments available.

Prescribing BAXDELA® 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.

Fluoroquinolones have been associated with disturbances of blood glucose, including symptomatic hyperglycemia and hypoglycemia. Severe cases of hypoglycemia resulting in coma or death have been reported with other fluoroquinolones. Monitor blood glucose carefully in diabetic patients receiving oral hypoglycemic agents or insulin. Discontinue BAXDELA® and initiate appropriate therapy immediately if a hypoglycemic reaction occurs.

Adverse Reactions

The most common adverse reactions in patients treated with BAXDELA® were nausea (8%), diarrhea (8%), headache (3%), transaminase elevations (3%), and vomiting (2%).

About VABOMERE® (meropenem and vaborbactam)

VABOMERE® is indicated for the treatment of patients 18 years of age and older with complicated urinary tract infections (cUTI) including pyelonephritis caused by the following susceptible microorganisms: Escherichia coli, Klebsiella pneumoniae, and Enterobacter cloacae species complex.

IMPORTANT SAFETY INFORMATION

Contraindications

VABOMERE® is contraindicated in patients with known hypersensitivity to any components of VABOMERE® (meropenem and vaborbactam), or to other drugs in the same class or in patients who have demonstrated anaphylactic reactions to beta-lactam antibacterial drugs.

Warnings and Precautions

Hypersensitivity reactions were reported in patients treated with VABOMERE® in the clinical trials. Serious and occasionally fatal hypersensitivity (anaphylactic) reactions and serious skin reactions have been reported in patients receiving therapy with beta-lactam antibacterial drugs. There have been reports of individuals with a history of penicillin hypersensitivity who have experienced severe hypersensitivity reactions when treated with another beta-lactam antibacterial drug. If an allergic reaction to VABOMERE® occurs, discontinue the drug immediately.

Seizures and other adverse Central Nervous System (CNS) experiences have been reported during treatment with meropenem, which is a component of VABOMERE®. Close adherence to the recommended dosage regimens is urged, especially in patients with known factors that predispose to convulsive activity.

Clostridioides difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including VABOMERE, and may range in severity from mild diarrhea to fatal colitis. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibacterial drug use not directed against C. difficile may need to be discontinued.

The concomitant use of VABOMERE® and valproic acid or divalproex sodium is generally not recommended. Case reports in the literature have shown that co-administration of carbapenems, including meropenem, to patients receiving valproic acid or divalproex sodium results in a reduction in valproic acid concentrations. The valproic acid concentrations may drop below the therapeutic range as a result of this interaction, therefore increasing the risk of breakthrough seizures. If administration of VABOMERE® is necessary, consider supplemental anticonvulsant therapy.

In patients with renal impairment, thrombocytopenia has been observed in patients treated with meropenem, but no clinical bleeding has been reported.

Alert patients receiving VABOMERE® on an outpatient basis regarding adverse reactions such as seizures, delirium, headaches and/or paresthesias that could interfere with mental alertness and/or cause motor impairment.

Prescribing VABOMERE® in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient and increases the risk of drug-resistant bacteria.

As with other antibacterial drugs, prolonged use of VABOMERE® may result in overgrowth of nonsusceptible organisms.

Adverse Reactions

The most frequently reported adverse reactions occurring in ≥3% of patients treated with VABOMERE® were headache, phlebitis/infusion site reactions, and diarrhea.
