-- Single Ascending Dose Study-Results Demonstrate Excellent Safety and Tolerability and Support Once-Weekly IV Dosing --

-- Management to Host Webcast and Conference Call Tomorrow at 8:00 a.m. ET --

SAN DIEGO, Nov. 16, 2015 (GLOBE NEWSWIRE) -- Cidara Therapeutics, Inc. (Nasdaq: CDTX ), a biotechnology company developing novel anti-infectives and immunotherapies to treat fungal and other infections, today announced positive data from the company's Phase 1 single ascending dose (SAD) clinical trial of its antifungal drug candidate, CD101 IV, in healthy volunteers. CD101 IV is a novel, long-acting echinocandin that Cidara is developing for the treatment and prevention of serious, invasive fungal infections, including candidemia and invasive candidiasis. The company also reported financial results for the three and nine months ended September 30, 2015.

Key results of CD101 IV single ascending dose trial:

• Well tolerated systemically and at infusion site across entire dose range
• No serious or severe adverse events and no dose response in adverse events
• No clinical chemistry, hematology or ECG safety concerns
• Pharmacokinetics consistent with preclinical data and supportive of once weekly dosing

"There are no long-acting antifungal drugs, including the approved echinocandins, that have suitable pharmacokinetics, potency and safety to enable a once-weekly, high-exposure treatment regimen," said Dirk Thye, M.D., chief medical officer of Cidara. "We are extremely encouraged by the Phase 1 SAD study data, which demonstrate that CD101 IV was well tolerated across a broad range of doses, and provides evidence that a once-weekly, high-exposure dosing regimen may be safely developed to improve patient outcomes and economic measures in a variety of clinical settings."

The CD101 IV Phase 1 SAD trial was a randomized, double-blind, placebo-controlled, dose-escalation study designed to establish the safety, tolerability, and pharmacokinetics of single intravenous doses of CD101 IV. The study enrolled 32 healthy adult volunteers in dose cohorts of 50 mg, 100 mg, 200 mg, and 400 mg. In each cohort of eight subjects, six subjects received CD101 IV and two subjects received placebo. Subjects were monitored for safety assessments and pharmacokinetics for three weeks following infusion.

"The future development path of CD101 IV, and our ability to strongly differentiate it from other antifungals, depended on the results of this single ascending dose study," said Jeff Stein, Ph.D., president and CEO of Cidara. "We now look forward to seeing results from the multiple ascending dose study in early 2016 to further evaluate the potential of CD101 IV as the first once-weekly echinocandin that could replace the need for an oral agent and thereby enable early hospital discharge and, for the first time, greatly facilitate continued use of an echinocandin outside the hospital."

Based on the results from the single and multiple ascending dose studies, Cidara plans to initiate a Phase 2 trial of CD101 IV in candidemia in the first half of 2016. More information about the Phase 1 trials for CD101 IV is available on ClinicalTrials.gov using the study codes for the SAD trial: NCT02516904 and the MAD trial: NCT02551549.

Third Quarter and Nine Months Ended September 30, 2015 Financial Results

• Research and development expenses were $6.8 million and $15.9 million for the three and nine months ended September 30, 2015, respectively, compared to $2.0 million and $3.2 million for the same periods in 2014. The increases for the 2015 periods, as compared to the same periods in 2014, were primarily attributable to the expansion of the company's product candidate pipeline to include CD101 IV and CD101 topical and the personnel-related costs associated with expanding our workforce.  
• General and administrative expenses were $2.4 million and $6.5 million for the three and nine months ended September 30, 2015, respectively, compared to $1.3 million and $2.1 million for the same periods in 2014. The increases resulted primarily from personnel-related costs to support the growth of our operating activities as well as public company operating costs.  
• Net loss for the three months ended September 30, 2015 was $9.2 million, compared to $3.3 million for the third quarter of 2014. For the nine months ended September 30, 2015, net loss was $22.3 million, compared to $7.2 million for the same period in 2014.  
• Cash, cash equivalents and short-term investments totaled $114.4 million as of September 30, 2015. As of November 10, 2015, Cidara had 13,719,665 common shares outstanding.
