Cellceutix Submits     Special Protocol Assessment Request to FDA for Phase 3 Clinical Trial of      Brilacidin for ABSSSI
  Study Titled: "A Phase 3, Multicenter,     Double-Blind, Randomized Study to Evaluate the Efficacy and Safety of     Single-Dose IV Brilacidin Versus IV Vancomycin Followed by Optional PO     Linezolid for the Treatment of Patients With Acute Bacterial Skin and Skin     Structure Infections (ABSSSI)"
  BEVERLY, MA--(Marketwired -     February 26, 2016) - 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 it has submitted a Special Protocol Assessment     (SPA) request, along with a final protocol to FDA, for a phase 3 clinical     trial of its novel single-dose antibiotic, Brilacidin, for the treatment     of Acute Bacterial Skin and Skin Structure Infection (ABSSSI) caused by     Gram-positive bacteria, including methicillin-resistant Staphylococcus      aureus (MRSA). A SPA is a written agreement between the U.S. Food and Drug     Administration (FDA) and a drug sponsor detailing the clinical trial     design, endpoints and other clinical trial facets that can be used to     support regulatory approval, thereby potentially reducing the risk of     bringing a drug to market. The SPA submission is the next step in     beginning a phase 3 program in ABSSSI after a successful End-of-Phase 2     Meeting with FDA last July (2015). The title of the protocol submitted     with the SPA request is: "A Phase 3, Multicenter, Double-Blind, Randomized     Study to Evaluate the Efficacy and Safety of Single-Dose IV Brilacidin     versus IV Vancomycin Followed by Optional PO Linezolid for the Treatment     of Patients with Acute Bacterial Skin and Skin Structure Infections     (ABSSSI)".
  Brilacidin is the lead compound in a new class of     antibiotics, the HDP mimics. It is the first completely novel antibiotic     to enter a Phase 3 trial in ABSSSI in more than two decades and is     uniquely qualified to treat Gram-positive pathogens, particularly MRSA,     without adding to the burden of antimicrobial resistance. Brilacidin     offers several key advantages over recently approved ABSSSI antibiotics,     which are newer members of existing antibiotic classes and, as such, are     more prone to the development of cross-resistance among bacteria. Like     other single-dose ABSSSI regimens, Brilacidin maximizes adherence to the     full treatment course, and therefore removes non-compliance as a driver of     resistance. However, Brilacidin has the advantage of an intermediate     half-life, while other single-dose ABSSSI regimens have very long     half-lives, which means these drugs can remain in the body for weeks at     low levels, which could further promote the development of resistance.     Moreover, Brilacidin has activity against stationary phase bacteria, which     play a role in persistent infections and biofilm formation. Finally,      Brilacidin has anti-inflammatory properties that may accelerate and     promote clinical healing. FDA designated Brilacidin as a Qualified     Infectious Disease Product (QIDP) under the GAIN Act in November, 2014.

  About      Cellceutix:
  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 multiple diseases. 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 concluded a     Phase 1 clinical trial at Harvard Cancer Centers' Dana Farber Cancer     Institute and Beth Israel Deaconess Medical Center, and Cellceutix is now     preparing its FDA application for a Phase 2 ovarian cancer study. 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 in a Phase 2 trial. 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.
