Cellceutix Provides Corporate Update; Significant Milestones Ahead as Multiple Mid-Phase Clinical Trials Set to Conclude

BEVERLY, MA – May 10, 2017 (GLOBE NEWSWIRE) Cellceutix Corporation, (OTCQB: CTIX) (“the Company”), a clinical stage biopharmaceutical company developing innovative therapies with dermatology, oncology, anti-inflammatory and antibiotic applications, today is pleased to provide a corporate update on current operations and upcoming clinical milestones across its pipeline of First-in-Class drug candidates, Prurisol, Kevetrin and Brilacidin, as summarized in our recent Quarterly Report (Form 10-Q), available for download at the link below.


Clinical Highlights and Upcoming Milestones

·      This week Cellceutix anticipates enrolling the final patients for the Brilacidin 42-day Ulcerative Proctitis/Ulcerative Proctosigmoiditis (UP/UPS) clinical study. 

·      Between patients already enrolled and those presently in screening, Cellceutix has reached over 70 percent of the anticipated number of trial participants in its Phase 2b trial of Prurisol for the treatment of moderate-to-severe chronic plaque psoriasis. Interim analysis top-line results are expected to be available during the third quarter of calendar year 2017.

·      Interim analysis of patients in the Phase 2 trial of Brilacidin-Oral Mucositis (OM) who received at least 55 Gy cumulative units of radiation showed that Brilacidin markedly reduced the rate of Severe OM (WHO Grade ≥ 3): Active Arm (Brilacidin): 2 of 9 patients (22.2 percent); Control Arm (Placebo): 7 of 10 patients (70 percent).

·      Concurrent with the Phase 2 clinical trial of intravenous-administered Kevetrin for late-stage ovarian cancer, toxicology studies are ongoing with the purpose of developing an oral formulation of Kevetrin for treating solid tumors. Currently, there are no approved p53-modulating cancer drugs, much less in pill form. 

Prurisol—Psoriasis: Interim Analysis of Phase 2b trial (3Q2017).

The ongoing randomized, double-blind, parallel-group and placebo-controlled study (see NCT02949388) increases the total daily oral dosing of Prurisol from a previous high of 200 mg, which earlier was shown to be well-tolerated and efficacious, to include oral Prurisol 300 mg per day, oral Prurisol 400 mg per day, and placebo (3:1:3 randomization). Enrolling approximately 189 patients with moderate-to-severe chronic plaque psoriasis, treatment duration is 12 weeks (84 days). Interim analysis is planned at 6 weeks. Currently, between patients already enrolled and those presently in screening, the Company has reached over 70 percent of the anticipated number of trial participants. Efficacy is being evaluated using the Psoriasis Area and Severity Index (PASI). Cellceutix believes now is an opportune time to develop an oral treatment for psoriasis. Currently approved treatments, including injectable biologics, are limited, with many options costly, not easily administered, associated with undesirable side-effects and/or diminishing effectiveness over time. A novel psoriasis drug, particularly one that is oral, safe and effective, which could expand patient and physician choices for treatment, likely would command significant market value.

Kevetrin—Ovarian Cancer: Completion of Phase 2a trial (2H2017).

The ongoing open-label study (see NCT03042702) is evaluating intravenous (IV) administration of Kevetrin 3 times per week, over 3 weeks, at an initial dose of 250mg/m2, with dose escalation in the 2nd cohort, in patients with platinum-resistant ovarian cancer. Modulation of the p53 pathway to further inform Kevetrin’s mechanism of action (MOA) is being measured via various RNA and protein biomarkers. Endpoints will include safety, efficacy (based on RECIST criteria) and pharmacodynamics. Running in parallel, the Company continues to make substantial progress in developing Kevetrin as an oral formulation. Preliminary bioavailability and other laboratory studies are encouraging and support its potential as an oral formulation. Currently there are no approved p53-modulating drugs, much less in pill form. An oral formulation of Kevetrin one day could position the drug candidate as a go-to cancer treatment.

Brilacidin—Oral Mucositis: Completion of Phase 2 trial (2H2017).

The ongoing randomized, double-blind, placebo-controlled study (see NCT02324335) is evaluating Brilacidin as an oral rinse, 3 times daily for 7 weeks, to prevent and control Oral Mucositis (OM) in patients receiving chemoradiation therapy for Head and Neck Cancer. Even though over 450,000 patients in the U.S. suffer from this condition, presently there are no approved drugs for the treatment of OM in this population, with only limited palliative care options available. In March 2017, preliminary interim analysis revealed that Brilacidin markedly reduced the occurrence of Severe OM, defined as Grade ≥ 3 on the World Health Organization OM Grading Scale—only 2 of 9 patients (22.2%) receiving Brilacidin developed Severe OM compared to 7 of 10 (70%) patients on placebo. Cellceutix’s goal with this trial is to show that Brilacidin has dual functionality in preventing the onset of the condition and shortening the duration of OM, an accomplishment no other pharmaceutical company has achieved.

Brilacidin—Ulcerative Proctitis/Ulcerative Proctosigmoiditis (UP/UPS): Completion of Phase 2a trial (2Q2017).

The ongoing open-label, proof-of-concept trial includes enrolling 18 patients treated with Brilacidin divided evenly into three cohorts (6 patients per cohort)—Cohort A (50 mg); Cohort B (100 mg); Cohort C (200 mg). In March 2017, after Cohorts A and B were completed (presently, three patients in Cohort C have completed their treatment), Cellceutix released interim results. The Primary Efficacy Endpoint of Clinical Remission (accounting for Stool Frequency, Rectal Bleeding and Endoscopy Findings subscores) was met by 50 percent of patients in Cohort A (3 of 6) and 50 percent of patients in Cohort B (3 of 6); all 6 of the remaining patients in Cohorts A and B had a Partial Response, as they met 2 of the 3 specified criteria. Brilacidin was generally well-tolerated. Patient Quality of Life (as assessed by the Short Inflammatory Bowel Disease Questionnaire, SIBDQ) showed notable improvements in all 12 patients. Limited systemic exposure to Brilacidin was demonstrated as measured by plasma Brilacidin concentrations. These data, along with the OM findings, suggest that other inflammatory conditions may, likewise, be treated locally and efficaciously with Brilacidin.

Financial Highlights

Cash Position—As of March 31, 2017, the Company had approximately $5.6 million in cash and $16 million remaining available for stock sales under the terms of the purchase agreement with Aspire Capital, compared to $6.3 million of cash as of June 30, 2016.

Shelf Registration—The Company has in place an effective shelf registration statement on Form S-3, registering the sale of up to $75 million of the Company’s securities, with approximately $42.8 million remaining available.

Management Discussion—The Company anticipates that future budget expenditures will be approximately $14 million over the next 12 months, including approximately $10 million for clinical trials. Management believes that financing available from Aspire Capital and under the Company’s effective Form S-3 shelf registration statement as well as any potential future Form S-1 filing to register the sale of its securities will be sufficient to fund the Company’s operations for the next 12 months.

“We are extremely proud of our accomplishments to date and are thrilled at the company’s prospects going forward into the latter half of 2017,” said Leo Ehrlich, Chief Executive Officer of Cellceutix. “Within a matter of months, we anticipate completing multiple mid-phase clinical trials for indications in areas with serious unmet medical needs. Based on highly encouraging clinical data received so far, we look forward to sharing complete clinical results with shareholders, members of the pharmaceutical industry interested in our drug candidates, and the public at large, to further establish the true potential of our clinical pipeline.”

“Much-needed drugs and tremendous value creation await patients and shareholders alike should we continue to deliver compelling trial results,” commented Arthur P. Bertolino, MD, PhD, MBA, President and Chief Medical Officer at Cellceutix.
