Cellceutix to Start Brilacidin Phase 3 Program in ABSSSI

Company Reports Successful End-of-Phase 2 Meeting With FDA


BEVERLY, MA--(Marketwired - July 20, 2015) - Cellceutix Corporation (OTC: CTIX) (the "Company"), a clinical stage biopharmaceutical company developing innovative therapies with oncology, dermatology, anti-inflammatory and antibiotic applications, is pleased to announce that the U.S. Food and Drug Administration (FDA) has agreed to advancing brilacidin into phase 3 for the treatment of Acute Bacterial Skin and Skin Structure Infections (ABSSSI).

During a recently held End-of-Phase 2 Meeting, Cellceutix and the FDA discussed safety and efficacy data that support advancement into phase 3, as well as the basic elements of a phase 3 program. The planned phase 3 program would include two phase 3 ABSSSI studies, as required by FDA Guidance. In addition, the first study would include an interim analysis after a portion of the patients has been enrolled. This would provide an early assessment of both safety and efficacy. As part of the agreement, the Company would submit a Pediatric Study Plan (PSP) within 60 days of the End-of-Phase 2 Meeting.

Dr. Daniel Jorgensen, Cellceutix's Chief Medical Officer and leader of the team that met with the FDA, was pleased with the outcome of the meeting. "This was a collaborative meeting, and the FDA was extremely helpful in providing guidance on our clinical development program in ABSSSI. The plan for an interim analysis makes sense, as this is a brand new class of antibiotics."

Brilacidin is the lead compound in a new class of antibiotics known as the defensin-mimetics. These compounds mimic the host defense proteins of the innate immune system, and therefore, have both antibacterial and immunomodulatory properties. Brilacidin has been administered intravenously in over 400 subjects in phase 1 and phase 2, and is currently being evaluated in a phase 2 study as a topical rinse for the prevention and treatment of oral mucositis in cancer patients.

Brilacidin was granted Qualified Infectious Disease Product (QIDP) designation by the FDA in November 2014. The QIDP designation was established as part of the Generating Antibiotic Incentives Now (GAIN) Act for the purpose of encouraging development of new antimicrobial drugs to treat serious and life-threatening infections. Receiving QIDP designation means that brilacidin is now eligible for additional FDA incentives, including Fast Track designation and Priority Review for clinical development, and a five-year extension of market exclusivity.

Headquartered in Beverly, Massachusetts, Cellceutix is a publicly traded company under the symbol "CTIX". Cellceutix is a clinical stage biopharmaceutical company developing innovative therapies in oncology, dermatology and antimicrobial applications. Cellceutix believes it has a world-class portfolio of compounds and is now engaged in advancing its compounds and seeking strategic partnerships. Cellceutix's anti-cancer drug Kevetrin is currently in a Phase 1 clinical trial at Harvard Cancer Centers' Dana Farber Cancer Institute and Beth Israel Deaconess Medical Center. In the laboratory Kevetrin has shown to induce activation of p53, often referred to as the "Guardian Angel Gene" due to its crucial role in controlling cell mutations. Cellceutix is in a Phase 2 clinical trial with its novel compound Brilacidin-OM for the prevention of Oral Mucositis in patients with head and neck cancer. Brilacidin-OM, a defensin mimetic compound, has shown in an animal model to reduce the occurrence of severe ulcerative oral mucositis by more than 94% compared to placebo. Cellceutix's anti-psoriasis drug Prurisol is being readied for a Phase 2 trial scheduled to begin July 28, 2015. Prurisol is a small molecule that acts through immune modulation and PRINS reduction. Cellceutix's lead antibiotic, Brilacidin, has completed a Phase 2b trial for Acute Bacterial Skin and Skin Structure Infections, or ABSSSI. Top-line data have shown a single dose of Brilacidin to deliver comparable clinical outcomes to the FDA-approved seven-day dosing regimen of daptomycin. Brilacidin has the potential to be a single-dose therapy for certain multi-drug resistant bacteria (Superbugs). Cellceutix has formed research collaborations with world-renowned research institutions in the United States and Europe, including MD Anderson Cancer Center, Beth Israel Deaconess Medical Center, and the University of Bologna.
