- Inter-agency collaboration among BARDA, DTRA, USAMRIID and Spero to fund further clinical development of product candidate SPR994
- Planned pivotal Phase 3 trial of SPR994 on track to initiate around year-end 2018
CAMBRIDGE, Mass., July 16, 2018 (GLOBE NEWSWIRE) -- Spero Therapeutics, Inc. (Nasdaq:SPRO) (Spero), a multi-asset clinical-stage biopharmaceutical company focused on developing and commercializing novel antibiotics to treat multi-drug resistant bacterial infections, today announced that it was awarded funding of $15.7 million, with the potential for up to an additional $28.5 million over 5 years, from the Biomedical Advanced Research and Development Authority (BARDA). The funding will support the further clinical development of Spero’s oral carbapenem product candidate, SPR994, for the treatment of complicated urinary tract infections (cUTIs) caused by antibiotic resistant Gram-negative bacteria. As part of the inter-agency collaboration with Spero, a series of studies to assess the efficacy of SPR994 in the treatment of infections caused by biodefense threats such as anthrax, plague and melioidosis will be conducted by the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID). In addition, the Defense Threat Reduction Agency (DTRA) will provide support up to $10 million to fund the nonclinical biodefense aspects of the inter-agency collaboration. The collaboration may also include a clinical trial in pneumonia patients, an indication for which tebipenem, SPR994’s active pharmaceutical ingredient, is currently approved in Japan for pediatric use. Together, the two agencies will provide up to $54.2 million in total funding for the clinical development and biodefense assessment of SPR994, a portion of which is subject to the exercise of options by BARDA and Spero’s achievement of specified milestones.
“We are honored to be the recipient of an award and to join BARDA and DTRA in this unique inter-agency collaboration. We look forward to advancing SPR994 through clinical development for public and biodefense use as we target public health needs caused by emerging drug-resistant infections,” said Ankit Mahadevia, M.D., CEO of Spero Therapeutics. “We believe the funding is a validation of the clinical potential of SPR994 across a broad treatment landscape, and of the ability of a small biotech company to work towards bringing these innovative therapies to patients in collaboration with our partners at BARDA and DTRA.”
The award from BARDA commits $15.7 million of guaranteed initial funding and up to an additional $28.5 million over 5 years if BARDA exercises all of its options under the award. Additionally, DTRA will commit $1.25 million of initial support, and up to an additional $8.75 million upon the achievement of specified milestones.
SPR994 is Spero’s novel investigational oral formulation of tebipenem, a carbapenem-class antibiotic marketed by Meiji Seika Pharma Co. Ltd. (Meiji) in Japan as Orapenem® since 2009 for common pediatric infections. Carbapenems are an important class of antibiotics because they have been demonstrated to be safe and effective against drug-resistant Gram-negative bacterial infections. Spero initiated a Phase 1 clinical trial of SPR994, designed as a double-blind, placebo-controlled, ascending dose, multi-cohort study, in healthy subjects in October 2017. The trial is assessing the safety, tolerability, and pharmacokinetics of SPR994 to enable dose selection for Spero’s planned pivotal Phase 3 clinical trial. Spero announced interim Phase 1 data from the trial in early July and expects to report final data from the MAD portion of the Phase 1 clinical trial in the third quarter of 2018. Pending discussions from a pre-Phase 3 meeting with the FDA, which Spero plans to request in the second half of 2018, Spero plans to initiate a pivotal Phase 3 clinical trial of SPR994 for the treatment of cUTI around year-end 2018 in support of a new drug application (NDA). In preclinical studies, SPR994 has shown potent antibiotic activity against Gram-negative bacteria, including E. coli-producing extended-spectrum beta-lactamases (ESBLs) and ESBL-producing Klebsiella pneumoniae, similar to IV-administered ertapenem. Approximately 1,200 subjects have been dosed with tebipenem in clinical and pharmacologic studies conducted by Meiji during its development of tebipenem in Japan. In addition, available post-marketing outcomes data report the safety and efficacy of tebipenem in 3,540 pediatric patients with pneumonia, otitis media or sinusitis, and these data are consistent with the safety profile of tebipenem as observed in the clinical trial conducted by Meiji.
Spero is a multi-asset, clinical-stage biopharmaceutical company focused on identifying, developing and commercializing novel treatments for multidrug-resistant (“MDR”) bacterial infections.
Spero’s lead product candidate, SPR994, is designed to be the first broad-spectrum oral carbapenem-class antibiotic for use in adults to treat MDR Gram-negative infections.
Spero also has a platform technology known as its Potentiator Platform that it believes will enable it to develop drugs that will expand the spectrum and potency of existing antibiotics, including formerly inactive antibiotics, against Gram-negative bacteria. Spero’s lead product candidates generated from its Potentiator Platform are two intravenous, or IV,-administered agents, SPR741 and SPR206, designed to treat MDR Gram-negative infections in the hospital setting.
Spero is also advancing SPR720, its novel oral therapy product candidate designed for the treatment of pulmonary non-tuberculous mycobacterial infection.
