CAMBRIDGE, Mass.--(BUSINESS WIRE)--Mar 14, 2019--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 (MDR) bacterial infections and rare diseases, today announced financial results for the fourth quarter and full year ended December 31, 2018 and provided a pipeline review.

“In 2018, we made significant progress advancing our pipeline candidates, all of which are designed to address serious unmet needs of multi-drug resistant infections,” said Ankit Mahadevia, M.D., Chief Executive Officer of Spero Therapeutics. “SPR994 is now entering a single pivotal Phase 3 clinical trial required for regulatory approval in cUTI, after we successfully identified a dose based on a completed Phase 1 clinical trial of SPR994 in 2018 and filed an IND with the FDA in early 2019. Additionally, we advanced SPR720 and SPR206 into Phase 1 clinical trials based on successful preclinical testing conducted in 2018. We look forward to an eventful 2019 with enrollment into our planned SPR994 Phase 3 trial, as well as Phase 1 data from SPR720 and SPR206 clinical trials expected in the second half of 2019.”

Recent Clinical Highlights and Upcoming Milestones

SPR994:

Spero’s lead product candidate, SPR994, is designed to be the first oral carbapenem antibiotic approved for use in adults to treat MDR Gram-negative infections. In February 2019, Spero announced the FDA’s acceptance of the IND application for SPR994 in cUTI, enabling Spero to initiate U.S. enrollment in its planned global, single pivotal Phase 3 clinical trial of SPR994 in cUTI entitled ADAPT-PO. The pivotal Phase 3 clinical trial is designed as a double-blind, double-dummy trial to compare oral SPR994 with an existing standard of care intravenous (IV) antibiotic, ertapenem, in approximately 1,200 patients randomized 1:1 in each arm. Spero has begun start-up activities for the ADAPT-PO clinical trial and anticipates opening trial sites around the end of March 2019 to support study enrollment. The trial will incorporate a lead-in cohort of 70 patients with an intensive pharmacokinetics assessment to confirm the dose and exposure in the cUTI patient population. Spero expects to receive pharmacokinetic data from the lead-in cohort in the second half of 2019.

SPR720:

SPR720 is an orally administered antimicrobial agent being developed for the treatment of a rare, orphan disease, non-tuberculous mycobacterial (NTM) infections. Pre-clinical  in vitro  and  in vivo  studies have demonstrated the potency of SPR720 against a range of bacteria that cause pulmonary NTM infections, including  Mycobacterium avium  complex and  Mycobacterium abscessus. The collective data to date suggest that SPR720 has an acceptable safety profile, encouraging target pathogen efficacy, drug distribution to key sites of infection, such as the lung, and a wide therapeutic margin. Spero initiated a SPR720 Phase 1 clinical trial in January 2019 designed as a double-blind, placebo-controlled clinical trial to assess the safety, tolerability and pharmacokinetics of SPR720 in healthy volunteers. Spero expects to receive top-line data from the Phase 1 clinical trial in the second half of 2019.

SPR206:

SPR206 is an IV-administered product candidate from Spero’s Potentiator Platform being developed as an innovative option to treat MDR Gram-negative bacterial infections. In preclinical studies, SPR206 showed activity as a single agent against MDR and extensively drug resistant (XDR) bacterial strains, including isolates of Pseudomonas aeruginosa, Acinetobacter baumannii and carbapenem-resistant Enterobacteriaceae, in both in vitro and in vivo models of infection. Spero initiated a Phase 1 clinical trial of SPR206 in December 2018, designed as a double-blind, placebo-controlled, ascending dose, multi-cohort study in healthy subjects. Spero expects to receive top-line data from this trial in the second half of 2019.

Fourth Quarter and Full-year 2018 Financial Results

Spero reported a net loss for the fourth quarter and year ended December 31, 2018 of $10.6 million and $41.7 million, or $0.60 and $2.60 per common share, respectively. Net loss for the fourth quarter and year ended December 31, 2017 was $14.8 million and $46.1 million, or $1.59 and $17.82 per common share, respectively.

Grant revenue for the fourth quarter and year ended December 31, 2018 totaled $1.7 million and $4.0 million, respectively, and was comprised of reimbursement for all of the pipeline programs. Grant revenue for the year ended December 31, 2018 was $2.0 million higher than the same period of 2017 due to an increase in available awards, such as the BARDA award of up to $44.2 million announced in July 2018, as well as a greater spend on our product candidates that was reimbursable under the awarded grants.

Research and development expenses for the fourth quarter 2018 of $9.1 million were lower than $12.5 million for the same period of 2017 due to lower direct clinical trial expense in the fourth quarter 2018 and the addition of milestone payments payable in the fourth quarter 2017. Research and development expenses for the year ended December 31, 2018 were $33.9 million compared to $32.9 million for the year ended December 31, 2017, with increased expenses in 2018 versus 2017 due to greater spend on SPR994 and SPR720 program expenses partially offset by lower spend on the Potentiator Platform product candidates. The Company expects that its research and development expenses will increase throughout 2019 due to greater planned clinical spend associated with the SPR994 pivotal ADAPT-PO trial, as well as the SPR720 and SPR206 Phase 1 clinical trials, along with increased personnel spend to support such programs.

General and administrative expenses for the fourth quarter 2018 of $3.6 million were higher than $2.5 million for the same period of 2017, primarily due to increased headcount and greater costs associated with operating as a public company. General and administrative expenses for the year ended December 31, 2018 were $12.9 million compared to $10.8 million for the year ended December 31, 2017, with the increased expenses in 2018 versus 2017 primarily due to an increase in headcount partially offset by lower professional and consultant fees. The Company expects general and administrative expenses to increase in 2019 due to additional headcount and professional fees to support the advancement of its lead asset SPR994 towards regulatory approval.

As of December 31, 2018, the Company had cash and cash equivalents of $115.4 million. Spero believes that its existing cash, cash equivalents and marketable securities, together with the initial funding committed under its BARDA award, will enable funding of operating expenses and capital expenditure requirements into the second half of 2020, including through the top-line data readout of the planned pivotal ADAPT-PO clinical trial of SPR994.
