Tebipenem HBr advancing towards NDA submission in the second half of 2021
Conference call and live webcast at 4:30 p.m. EST today
CAMBRIDGE, Mass., March 11, 2021 (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 financial results for the fourth quarter and full-year ended December 31, 2020 and provided a business update.
“Over the last year we have made significant progress and completed critical milestones despite the industry-wide challenges brought about by the COVID-19 pandemic,” said Ankit Mahadevia, M.D., Chief Executive Officer of Spero Therapeutics. “Chief among these milestones was our announcement in September 2020 that the tebipenem HBr ADAPT-PO Phase 3 clinical trial in complicated urinary tract infection (cUTI) and acute pyelonephritis (AP) met its primary endpoint. We look forward to another productive year in 2021, as we advance tebipenem HBr towards an NDA submission in the second half of 2021 and move closer to potentially addressing the unmet needs of the estimated 2.7 million cUTI and AP patients in the United States who may benefit from an oral treatment option that could prevent unnecessary hospitalizations.”
Clinical Highlights and Upcoming Milestones
Tebipenem HBr:
In September 2020, Spero announced positive data from the ADAPT-PO Phase 3 clinical trial demonstrating that oral tebipenem HBr was statistically non-inferior to intravenous ertapenem in the treatment of patients with cUTI and patients with AP with respect to the primary endpoint. The ADAPT-PO clinical trial was the first trial to evaluate an all-oral regimen of tebipenem HBr head-to-head versus an all intravenous (IV) regimen of ertapenem for the treatment of adults with cUTI and AP. The top-line data as well as additional analyses from the trial were subsequently presented at IDWeek in October 2020.
In January 2021, Spero announced that the U.S. Patent and Trademark Office (USPTO) issued U.S. Patent No. 10,889,587, which covers a crystalline formulation of tebipenem HBr. This patent expires in February 2038. Tebipenem HBr has also been granted Qualified Infectious Disease Product (QIDP) and Fast Track designations by the U.S. Food and Drug Administration (FDA) for the treatment of cUTI.
The Phase 1 clinical trials required for a new drug application (NDA) submission to the U.S. Food and Drug Administration (FDA) for tebipenem HBr have also been completed, and Spero remains on track to make an NDA submission to the FDA in the second half of 2021.
SPR720:
In December 2020, Spero initiated a Phase 2a dose-ranging clinical trial of oral SPR720 in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD). The advancement of SPR720 into the Phase 2a clinical trial was based on positive data from a Phase 1 clinical trial that evaluated the safety, tolerability and pharmacokinetics of 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.
In February 2021, following Spero’s notification to the FDA of Spero’s decision to pause dosing in its ongoing Phase 2a clinical trial of SPR720 as a precautionary measure related to data from an ongoing toxicology study of SPR720 in adult non-human primates in which mortalities with inconclusive causality to treatment were observed, the FDA issued a verbal notification of a clinical hold on the clinical trial. Subsequently, Spero received a formal clinical hold letter in which the FDA requested additional information from the non-human primate toxicology study, including a study report.
To best facilitate potential adjustments to the Phase 2a SPR720 clinical trial protocol that may be made in the future based on findings from the ongoing toxicology study and FDA feedback, and to avoid incurring costs associated with the clinical trial while it is on hold, Spero has decided to discontinue the Phase 2a clinical trial at this time. Spero continues to work with the FDA to evaluate the non-human primate toxicology study and determine the best development pathway for the SPR720 clinical program.
SPR206:
In January 2020, Spero reported positive Phase 1 clinical trial results for SPR206 in healthy volunteers. Under its agreement with Everest Medicines, Spero received a
