Allecra Therapeutics’ EXBLIFEP approved for the treatment of complicated urinary tract infections


The U.S. Food and Drug Administration (FDA) has approved Allecra Therapeutics’ EXBLIFEP® (cefepime/enmetazobactam) as a treatment for complicated urinary tract infections (cUTIs), including pyelonephritis, in patients 18 years and older.

Allecra has also received a five-year marketing exclusivity extension from the FDA as part of the Generating Antibiotic Incentives Now Act (GAIN Act). The GAIN Act, enacted by the U.S. Congress, incentivizes the creation of new anti-infective therapeutics by providing benefits to manufacturers of Qualified Infectious Disease Products (QIDPs).

“Receiving FDA approval is a tremendous achievement for Allecra and a testament to the hard work and dedication of a small, yet highly focused team of individuals. I extend my sincere congratulations to my colleagues Omar Lahlou and Patrick Velicitat for their leadership and oversight throughout this whole process,” said Iain Buchanan, Supervisory Board Member of Allecra Therapeutics.

“As we continue our discussions with strategic partners for product launch in the U.S., we value the FDA’s positive decision on EXBLIFEP®’s ability to address a critical unmet medical need for patients.”

The FDA’s approval of EXBLIFEP® was supported by a totality of clinical data that demonstrated EXBLIFEP® effectiveness against antimicrobial resistance in gram-negative bacteria, especially resistance mediated by both ESBL (Extended Spectrum Beta Lactamases) and AmpC.

This included results from Allecra’s Phase 3 ALLIUM trial, which met criteria for non-inferiority and superiority compared to piperacillin/tazobactam in the primary composite outcome of clinical cure and microbiological eradication in patients with cUTIs.

Allecra is the sole holder of a significant patent estate covering EXBLIFEP® in major territories with the GAIN Act extending Allecra’s market exclusivity until 2032. Enmetazobactam was first discovered by Orchid Pharma and all rights outside India were assigned to Allecra Therapeutics in 2013. The company has since taken the sole responsibility for the international clinical and regulatory development of EXBLIFEP®.

Allecra was founded through a strategic partnership formed by Nicholas Benedict, Stuart
Shapiro and Edward Currie in conjunction with Orchid Chemicals and Pharmaceuticals Ltd. and Allecra lead investors, Andera Partners, Forbion and EMBL Ventures. The company has concluded exclusive license agreements for EXBLIFEP® with Shanghai Haini Pharmaceutical in Greater China and ADVANZ PHARMA in Europe.
