Conference call and live webcast at 4:30 p.m. ET today
“We are off to a strong start in 2021 and I am very pleased with the progress we have made across our pipeline,” said
Clinical Highlights and Upcoming Milestones
Spero’s lead product candidate, tebipenem HBr, has the potential to be the first oral carbapenem antibiotic, if approved, to treat complicated urinary tract infection (cUTI), including acute pyelonephritis (AP). In
In December 2020, SPR720 advanced into a Phase 2a dose-ranging clinical trial in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD) based on positive data from a Phase 1 clinical trial that evaluated the safety, tolerability and pharmacokinetics of oral SPR720, as well as supportive data from a series of non-clinical GLP toxicology and safety pharmacology studies, including investigational new drug application (IND)-enabling 28- and 31-day GLP studies in non-human primates and rats, respectively.
SPR206 is an intravenously (IV)-administered product candidate being developed as an innovative option to treat multi-drug resistant (MDR) Gram-negative bacterial infections. In

First Quarter 2021 Financial Results
Spero reported a net loss for the first quarter ended March 31, 2021 of $19.4 million or $0.66 per common share, compared to a net loss of $23.3 million or $1.22 per common share reported for the same period in 2020.
Total revenues for the first quarter of 2021 were $7.3 million, compared with revenues of $1.7 million in the first quarter of 2020. The increase was primarily due to grant revenue received through the BARDA contract for tebipenem HBr.
Research and development expenses for the first quarter of 2021 were $18.4 million, compared with $20.4 million of research and development expenses for the same period of 2020. This year-over-year decrease was due to winding down of Phase 3 activities for tebipenem HBr, offset in part by investment to support the NDA filing for tebipenem HBr.
General and administrative expenses for the first quarter of 2021 of $8.3 million were higher than the $4.1 million reported in the same period of 2020, primarily due to increased professional expenses and personnel costs to support the Company’s precommercial efforts.
As of March 31, 2021, Spero had cash, cash equivalents, and marketable securities of $115.7 million. Spero believes that its existing cash, cash equivalents and marketable securities, together with committed funding from its BARDA contract and other non-dilutive funding commitments, will be sufficient to fund its operating expenses and capital expenditure requirements into the second quarter of 2022, including through the submission of the NDA for tebipenem HBr.

About Spero Therapeutics
Spero’s lead product candidate, tebipenem HBr (tebipenem pivoxil hydrobromide; formerly SPR994), is being developed as the first oral carbapenem antibiotic for use in complicated urinary tract infections (cUTI) and acute pyelonephritis (AP). In September 2020, Spero announced positive top-line results from its Phase 3 ADAPT-PO clinical trial of tebipenem HBr in cUTI and AP.
Spero is also developing SPR720, its novel oral therapy product candidate being developed for the treatment of rare, orphan pulmonary disease caused by non-tuberculous mycobacterial (NTM) infections.
Spero also has an IV-administered next generation polymyxin product candidate, SPR206, developed from its potentiator platform that is being developed to treat MDR Gram-negative infections in the hospital setting.
