Spero Therapeutics, Inc. (Nasdaq:SPRO), a multi-asset
clinical-stage biopharmaceutical company focused on identifying,
developing and commercializing novel treatments for
multidrug-resistant bacterial infections, announced today one oral
poster presentation and four paper poster presentations on SPR994
at the 29th European Congress of Clinical Microbiology and
Infectious Diseases (ECCMID) being held April 13-16,
2019 in Amsterdam, Netherlands. Presentations
will include data from Spero’s Phase 1 single ascending dose (SAD)
and multiple ascending dose (MAD) clinical trial of SPR994, Spero’s
lead product candidate designed to be the first oral carbapenem
antibiotic, as well as other posters supporting the SPR994 dose and
comparator agent selected for the pivotal Phase 3 clinical trial,
ADAPT-PO, for the treatment of complicated urinary tract infections
(cUTI).
“The data to be presented at ECCMID highlight
the utility of SPR994 in treating the serious unmet need of
multi-drug resistant infections and provide additional supporting
data for the design of the pivotal Phase 3 trial of SPR994 for the
treatment of cUTI,” said Ankit Mahadevia, M.D., CEO
of Spero Therapeutics.

About SPR994SPR994 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 pediatric
infections limited to pneumonia, otitis media and sinusitis.
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 completed a Phase 1
clinical trial of SPR994 in Australia, designed as a
double-blind, placebo-controlled, ascending dose, multi-cohort
study to enable dose selection for Spero’s planned pivotal Phase 3
clinical trial. The FDA has accepted Spero’s IND for
SPR994 in cUTI and Spero expects site initiation to commence
imminently to support enrollment into its pivotal Phase 3 clinical
trial of SPR994 entitled ADAPT-PO [A Phase 3, Randomized,
Double-blind, Double-dummy, Multicenter, Prospective Study to
Assess the Efficacy, Safety and Pharmacokinetics
of Orally Administered Tebipenem Pivoxil Hydrobromide (SPR994)
Compared to Intravenous Ertapenem in Patients with Complicated
Urinary Tract Infection (cUTI) or Acute Pyelonephritis (AP)].
SPR994 has been granted Qualified Infectious Disease Product (QIDP)
and Fast Track designations by the FDA. 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 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.
About Spero
Spero Therapeutics, Inc. is a multi-asset,
clinical-stage biopharmaceutical company focused on identifying,
developing and commercializing novel treatments for
multidrug-resistant (MDR) bacterial infections and rare
diseases.
Spero’s lead product candidate, SPR994, is
designed to be the first oral carbapenem-class antibiotic for use
in adults to treat MDR Gram-negative infections.
Spero is also advancing SPR720, its novel oral
therapy product candidate designed for the treatment of rare,
orphan disease caused by pulmonary non-tuberculous mycobacterial
(NTM) 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 IV-administered agents,
SPR206 and SPR741, designed to treat MDR Gram-negative infections
in the hospital setting.

Forward Looking Statements
This press release may contain forward-looking
statements. These statements include, but are not limited to,
statements about Spero’s expectation that positive results from a
single pivotal Phase 3 clinical trial of SPR994 and ancillary
supportive studies to be conducted in parallel with the planned
Phase 3 trial will support the approval of SPR994; the initiation,
timing, progress and results of Spero’s preclinical studies and
clinical trials and its research and development programs,
including the anticipated timing of the opening of sites to support
enrollment into the planned pivotal Phase 3 clinical trial of
SPR994; statements regarding management’s assessment of the results
of such preclinical studies and clinical trials; the timing of
clinical data, including the availability of pharmacokinetic data
from the lead-in cohort in the planned Phase 3 clinical trial of
SPR994 and top-line data from the Phase 1 clinical trial of SPR206
and the Phase 1 clinical trial of SPR720; and Spero’s cash forecast
and anticipated expenses, the sufficiency of its cash resources and
the availability of additional non-dilutive funding from
governmental agencies beyond any initially funded awards. In some
cases, forward-looking statements can be identified by terms such
as “may,” “will,” “should,” “expect,” “plan,” “aim,” “anticipate,”
“could,” “intent,” “target,” “project,” “contemplate,” “believe,”
“estimate,” “predict,” “potential” or “continue” or the negative of
these terms or other similar expressions. Actual results may differ
materially from those indicated by such forward-looking statements
as a result of various important factors, including whether
the FDA will accept a single pivotal study for approval
of SPR994; whether results obtained in preclinical studies and
clinical trials will be indicative of results obtained in future
clinical trials; whether Spero’s product candidates will advance
through the preclinical development and clinical trial process on a
timely basis, or at all, taking into account the effects of
possible regulatory delays, slower than anticipated patient
enrollment, manufacturing challenges, clinical trial design and
clinical outcomes; whether the results of such trials will warrant
submission for approval from the U.S. Food and Drug
Administration or equivalent foreign regulatory agencies;
whether Spero’s cash resources will be sufficient to fund its
continuing operations for the periods and/or trials anticipated;
and other factors discussed in the “Risk Factors” set forth in
filings that Spero periodically makes with the U.S. Securities
Exchange Commission. The forward-looking statements included in
this press release represent Spero’s views as of the date of this
press release. Spero anticipates that subsequent events and
developments will cause its views to change. However, while Spero
may elect to update these forward-looking statements at some point
