Management to host webcast and conference call tomorrow at 8:00 a.m. ET

CHAPEL HILL, N.C., May 01, 2016 (GLOBE NEWSWIRE) -- Cempra, Inc. (Nasdaq:CEMP), a clinical-stage pharmaceutical company focused on developing antibiotics to meet critical medical needs in the treatment of bacterial infectious diseases, today reported financial results for the quarter ended March 31, 2016 and provided an update on recent corporate developments. The company will host a webcast and conference call tomorrow at 8:00 a.m. ET.

First Quarter 2016 and Recent Corporate Highlights

• In April, Cempra completed its rolling submission of two New Drug Applications (NDA) to the U.S. Food and Drug Administration (FDA) for solithromycin (intravenous and capsules) in community-acquired bacterial pneumonia (CABP). Having been granted qualified infectious diseases product (QIDP) designation in 2013, solithromycin’s NDAs qualify for an eight month priority review. Subject to approval by the FDA, Cempra plans to launch solithromycin in the U.S. in the first quarter of 2017.
   
• In March, Cempra received authorization under its existing contract with the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response within the U.S. Department of Health and Human Services, to receive funding of $25.5 million through mid-2018 for a Phase 2/3 pivotal clinical study of solithromycin in pediatric patients. Cempra is responsible for an additional designated portion of the cost of the planned Phase 2/3 study. Three dosage formulations of solithromycin, intravenous, capsule and oral suspension, will be tested in the trial and may provide pediatricians with greater dosing flexibility.  
   
• In January, Cempra completed a public offering of 4,166,667 shares at a price of $24.00 per share. Net proceeds after underwriting discounts and commissions and expenses of the offering were approximately $93.8 million. Cempra intends to use the funds for the commercial launch of solithromycin in CABP in the U.S., subject to the drug receiving FDA approval, and on research and development activities, working capital and general corporate and administrative expenses.
   
• The Taksta™ (fusidic acid) acute bacterial skin and skin structure infection (ABSSSI) Phase 3 trial is enrolling patients, which is expected to be completed during the first half of 2017.

“I am truly delighted that Cempra is able to mark the tenth anniversary of its founding with our submission to the FDA of two NDAs for solithromycin in community-acquired bacterial pneumonia,” said Prabhavathi Fernandes, Ph.D., president and chief executive officer of Cempra. “As a new chemical entity, we expect that solithromycin will be subject to an advisory committee review, however given the compelling data package that we have assembled, we look forward to working with the agency during the review process to bring this important new macrolide antibiotic to patients with CABP and the physicians who treat them. Our development programs for solithromycin for pediatric patients and urogenital gonorrhea, as well our development program for Taksta, are continuing to move forward.” 

Upcoming Clinical Development Milestones

Solithromycin

• Solithromycin pediatric: patient enrollment for Phase 1b trial continues.
• Enrollment in a Phase 2/3 pivotal trial with solithromycin for bacterial infections in pediatric patients is expected to initiate in Q2 2016.
• Phase 3 trial for solithromycin in urogenital gonorrhea is ongoing.
• Phase 2 trial in chronic obstructive pulmonary disease (COPD) is ongoing.
• Phase 2 trial in nonalcoholic steatohepatitis (NASH) is ongoing.
• Completion of the EMA submission for solithromycin in the treatment of CABP is expected by the end of the first half of 2016.

Taksta

• Phase 3 trial in ABSSSI is ongoing.
• An exploratory trial for Taksta in patients with refractory bone or joint infections is ongoing.

Financial Results for the Three Months Ended March 31, 2016

For the quarter ended March 31, 2016, Cempra reported a net loss of $29.4 million, or $0.61 per share, compared to a net loss of $17.4 million, or $0.41 per share for the first quarter in 2015. Research and development expense in the first quarter of 2016 was $23.5 million, a decrease of 10% compared to the same quarter in 2015. The lower R&D expense was primarily due to the timing of payments for the order of active pharmaceutical ingredient (API) necessary to support the launch of solithromycin as the company begins its commercial readiness activities and a decrease in clinical expenses as the Phase 3 Oral and Phase 3 IV-to-Oral studies are complete. General and administrative expense was $8.3 million, a 79% increase compared to the quarter ended March 31, 2015, driven primarily by commercial readiness activities and increased headcount as the company begins to plan for commercialization.

As of March 31, 2016, Cempra had cash and equivalents of $223.6 million and 48.2 million shares outstanding.

Financial Guidance

The company's current cash and equivalents are expected to be sufficient to fund ongoing operations into the second quarter of 2017, assuming continued timely receipts under the BARDA contract and receipt of expected milestone payments from Toyama. This projection does not include any funds from new financings or partnerships.
