Melinta Therapeutics Receives Positive CHMP Opinion for Vabomere™ (meropenem and vaborbactam)

World News: . []

         

NEW HAVEN, Conn., Sept. 21, 2018 (GLOBE NEWSWIRE) -- Melinta Therapeutics, Inc. (NASDAQ: MLNT), a commercial-stage company discovering, developing and commercializing novel antibiotics to treat serious bacterial infections, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending Vabomere™ (meropenem and vaborbactam) for approval as a treatment for adult patients with complicated intra-abdominal (cIAI) and urinary tract infections (cUTI), hospital-acquired pneumonia including ventilator associated pneumonia (HAP/VAP), bacteraemia that occurs in association with any of these infections, and infections due to aerobic Gram-negative organisms where treatment options are limited.

The CHMP’s opinion will be reviewed by the European Commission (EC), which is expected to make a final decision regarding marketing authorization within 67 days of receiving the CHMP opinion. If approved by the EC, marketing authorization for Vabomere will be granted in all 28 countries of the European Union, Norway, Iceland and Liechtenstein. Milestone payment obligations related to Vabomere’s European approval would not take effect until marketing authorization is granted by the EC.

“We are encouraged by the CHMP’s positive recommendation for Vabomere, which brings us one step closer to providing access to this important treatment option for patients in Europe,” said Dan Wechsler, President and CEO of Melinta. “Additionally, we were pleased to see the range of indications recommended for approval, underscoring our belief that Vabomere represents a significant new advancement in addressing the increasing incidence of KPC-producing Enterobacteriaceae, for which there are currently limited treatment options.”

The CHMP opinion was supported by data from the TANGO clinical program, including data from TANGO-1, a Phase III, multi-center, randomized, double-blind, double-dummy study to evaluate the efficacy, safety and tolerability of Vabomere compared to piperacillin-tazobactam in the treatment of cUTI, including acute pyelonephritis, in adults, as well as TANGO-2, a multi-center, randomized, open-label clinical trial of Vabomere versus “best available therapy” in subjects with known or suspected carbapenem-resistant Enterobacteriaceae (CRE).

Vabomere was approved by the U.S. Food and Drug Administration (FDA) in August 2017 for the treatment of adult patients who have been diagnosed with complicated urinary tract infections (cUTIs), including pyelonephritis, caused by treatment of adult patients caused by designated susceptible Enterobacteriaceae – ,  and  complex. Vabomere is a drug containing meropenem, an antibacterial, and vaborbactam, which is a new class of beta-lactamase inhibitor that inhibits certain types of resistance mechanisms used by bacteria.

VABOMERE (meropenem and vaborbactam) 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: , , and complex.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of VABOMERE and other antibacterial drugs, VABOMERE should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.

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.

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 non-susceptible 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.
