CAMBRIDGE, Mass., Oct. 16, 2020 (GLOBE NEWSWIRE) — Spero Therapeutics, Inc. (Nasdaq: SPRO), a multi-asset clinical-stage biopharmaceutical company focused on identifying, developing and commercializing treatments in high unmet need areas involving multi-drug resistant bacterial infections and rare diseases, today announced that it will have 15 data presentations at the Infectious Disease Society of America (IDSA) IDWeek™ 2020 taking place virtually from October 21 – 25, 2020. Presentations will cover each of Spero’s three pipeline programs and include a late breaker oral presentation on the Phase 3 ADAPT-PO clinical trial that evaluated Spero’s oral antibiotic investigational candidate, tebipenem HBr, for the treatment of adults with complicated urinary tract infection (cUTI) and acute pyelonephritis (AP). In September 2020, Spero announced positive top-line data from the trial demonstrating that oral tebipenem HBr was statistically non-inferior to intravenous (IV) ertapenem in the treatment of patients with cUTI and patients with AP. Poster presentations include a poster on the Phase 1 clinical trial of SPR720, an oral antimicrobial investigational agent in clinical development by Spero for the treatment of nontuberculous mycobacterial (NTM) pulmonary disease. In December 2019, Spero announced positive data from this Phase 1 double-blind, placebo-controlled single ascending dose and multiple ascending dose clinical trial in healthy volunteers.

Tebipenem HBr (tebipenem pivoxil hydrobromide; formerly SPR994) is Spero’s novel investigational oral formulation of tebipenem pivoxil, a carbapenem antibiotic of the β-lactam class marketed by Meiji Seika Pharma Co. Ltd. (Meiji) in Japan as Orapenem® since 2009 for pediatric infections limited to pneumonia, otitis media and sinusitis. Orapenem® is not approved in the U.S. Carbapenems are an important subclass of antibiotics because they have been observed to be safe and effective in the treatment of drug-resistant Gram-negative bacterial infections. Tebipenem HBr is being developed for the treatment of cUTI, including AP. Spero expects to submit a New Drug Application submission to the U.S. Food and Drug Administration (FDA) for tebipenem HBr in the second quarter of 2021. If approved, tebipenem HBr would be the first oral carbapenem to receive marketing approval in the United States. Tebipenem HBr has been granted Qualified Infectious Disease Product (QIDP) and Fast Track designations by the FDA for the treatment of cUTI and AP.About SPR720
SPR720 represents a novel class of antibacterial agents in development that target enzymes essential for bacterial DNA replication. SPR720, an investigational new drug, was acquired from Vertex Pharmaceuticals and is currently under clinical development by Spero as an oral therapy for the treatment of non-tuberculous mycobacterial (NTM) pulmonary disease, a rare chronic orphan disease. Spero plans to initiate enrollment in its planned Phase 2a clinical trial evaluating SPR720 in patients with NTM pulmonary disease by year-end 2020.Non-tuberculous mycobacteria are ubiquitous environmental pathogens that can cause progressive lung damage and respiratory failure, particularly in patients with compromised immune systems or underlying pulmonary disorders. Although rare, the incidence of NTM pulmonary disease is increasing worldwide. Treatment of NTM pulmonary disease requires prolonged therapy (continuing for approximately 12 to 24 months) with a combination of drugs approved for other infections and is frequently complicated by tolerability and/or toxicity issues. There are currently no oral antibiotics specifically approved for use to treat NTM pulmonary disease. Thus, if successfully developed and approved by the FDA, SPR720 has the potential to address an important unmet need as the first oral antibiotic approved for the treatment of this debilitating disease. Under Spero’s collaboration with the Bill and Melinda Gates Medical Research Institute, SPR720 will also be developed for the treatment of Mycobacterium tuberculosis (M. tb) infections in select economically disadvantaged countries. M. tb is a priority pathogen as defined by the World Health Organization with tuberculosis being one of the top ten causes of death worldwide and associated with both increasing resistance and sub-optimal current treatment approaches. SPR720 has been granted QIDP designation by the FDA for the treatment of lung infections caused by NTM and lung infections caused by M. tb and Orphan Drug Designation by the FDA for the treatment of NTM infection.About SPR206
SPR206 is an investigational agent designed to be IV administered and act directly on Gram-negative bacterial infections through the molecule’s interactions with the bacterial outer membrane. SPR206 has demonstrated potent broad-spectrum activity against Gram-negative bacteria, including organisms identified by the Centers for Disease Control and Prevention and the World Health Organization as urgent and serious threats to human health. Spero expects to initiate a Phase 1 bronchoalveolar lavage clinical trial assessing the penetration of SPR206 into the pulmonary compartment in the first half of 2021 and initiate a renal impairment study of SPR206 in 2021. SPR206 has been granted QIDP designation by the FDA for the treatment of cUTI and hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (HABP/VABP).Tebipenem HBr Research Support
