Innovation Pharmaceuticals Completes Final Patient Visit in Phase 2b Study of Oral Prurisol for Psoriasis

Share:

BEVERLY, Mass., Dec. 21, 2017 (GLOBE NEWSWIRE) -- Innovation Pharmaceuticals Inc., (OTCQB:IPIX) ("the Company"), a clinical stage biopharmaceutical company, today announces all patient follow-up visits have been completed in its Phase 2b clinical study of oral Prurisol in moderate-to-severe chronic plaque psoriasis. Prurisol is being developed as a novel, nonbiologic, orally-delivered psoriasis drug candidate.

A total of 199 patients were randomized in the clinical trial (see NCT02949388), which included: a screening period of up to 4 weeks; a treatment period of 12 weeks; and a follow-up visit after 4 weeks off-treatment. The randomized, double-blind, parallel-group and placebo-controlled study increases the total daily oral dosing of Prurisol from a previous high of 200 mg, which earlier was shown to be well-tolerated and demonstrated early efficacy, to include oral Prurisol 300 mg per day, oral Prurisol 400 mg per day, and placebo (3:1:3 randomization). Efficacy evaluation includes the Psoriasis Area and Severity Index (PASI).

The Company believes now is an opportune time to develop an oral treatment for psoriasis. Currently approved treatments, including injectable biologics, are limited, with many options being 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, would expand patient and physician choices for treatment and likely would command significant market value.

The Company looks forward to seeing the unblinded study results. Topline data are anticipated to be released in 1Q2018.

About Prurisol
Acting through immune modulation and PRINS reduction, Prurisol is a novel dermatology compound currently in mid-stage development as an oral psoriasis treatment utilizing the advantages of the FDA's 505(b)(2) development approach. This regulatory approach helps expedite a drug candidate's approval as it allows the FDA to rely, in part, on existing clinical data from an already approved drug, in this instance, Ziagen. In laboratory studies, Prurisol was found to be effective against psoriasis in animal models, both in induced psoriasis and in a xenograft model using human psoriatic tissue. In these models, Prurisol eliminated virtually all signs of psoriasis. Innovation Pharmaceuticals has successfully completed a Phase 2 clinical trial of Prurisol in patients with mild-to-moderate chronic plaque psoriasis. Overall analyses showed that the drug candidate appeared to be safe, well-tolerated and efficacious in the highest dosing arm across 12 weeks of treatment. Patients with moderate psoriasis saw the greatest clinical improvements. An early dose-dependent response that improved as treatment duration increased was observed. Innovation Pharmaceuticals has since conducted a Phase 2b clinical trial of Prurisol in moderate-to-severe psoriasis, assessing the drug candidate's efficacy at higher dosing regimens. Topline Phase 2b data are expected in 1Q2018.

About Psoriasis
Affecting an estimated 125 million people worldwide, psoriasis is a chronic immune-mediated skin disorder presenting with varying symptoms and levels of severity. The condition is characterized by raised and inflamed skin, often on the elbows, knees, scalp, hands and feet, causing itching, irritation, stinging and pain. Often feeling socially stigmatized, over 80 percent of people with psoriasis report it negatively impacts the quality of their everyday life. Cases are graded as Mild, Moderate and Severe depending upon extent of body surface area involved as well as other parameters. Up to 30 percent of psoriasis patients will eventually develop psoriatic arthritis (PsA). Psoriasis also is associated with numerous comorbidities. Despite recent advances, there remains a need for orally-delivered psoriasis drugs and other treatment alternatives to biologics, which can be accompanied by side effects that significantly impact activities of daily living, and may lose their effectiveness over time.

About 505(b)(2) Development Approach
Under the FDA's 505(b)(2) development approach, a drug candidate's road to market approval can be significantly shortened and conducted at a much reduced cost. Long-term safety data from a reference drug may be relied upon for approval, and potentially only one pivotal Phase 3 study, enrolling a smaller number of patients than is typical, may be required to establish drug efficacy.

About the Company
Headquartered in Beverly, Massachusetts, Innovation Pharmaceuticals Inc. (IPI), formerly Cellceutix Corporation, is publicly-traded under the company symbol "IPIX". The Company is clinical stage biopharmaceutical company developing innovative therapies in multiple diseases. The Company believes it has a world-class portfolio of first-in-class lead drug candidates and is now advancing them toward market approval, while actively seeking strategic partnerships. The Company's Psoriasis drug candidate Prurisol completed a Phase 2 trial and the Company has since conducted a Phase 2b study, with topline results expected in 1Q2018. Prurisol is a small molecule that acts through immune modulation and PRINS reduction. The Company's anti-cancer drug Kevetrin successfully concluded a Phase 1 clinical trial at Harvard Cancer Centers' Dana Farber Cancer Institute and Beth Israel Deaconess Medical Center, and the Company has commenced a Phase 2 study in Ovarian Cancer. In the laboratory, Kevetrin has been shown to modulate p53, often referred to as the "Guardian Angel Gene" due to its crucial role in controlling cell mutations. Brilacidin, a defensin mimetic compound, has shown in an animal model to reduce the occurrence of severe ulcerative Oral Mucositis (OM) by more than 94% compared to placebo. The Company has recently completed a Phase 2 clinical trial with its novel compound Brilacidin-OM for the prevention of OM in patients with Head and Neck Cancer; topline results demonstrate a reduction in the incidence of severe OM (WHO Grade ≥ 3). The Company's lead antibiotic, Brilacidin, has completed a Phase 2b trial for Acute Bacterial Skin and Skin Structure Infection, or ABSSSI. The Phase 2b data showed 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"). Results are now available for the completed Phase 2, open label Proof-of-Concept trial, treating patients with Brilacidin for Ulcerative Proctitis/Ulcerative Proctosigmoiditis (UP/UPS), two types of Inflammatory Bowel Disease (IBD). The Company 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.
