BEVERLY, MA, USA I February 08, 2018 I Innovation Pharmaceuticals Inc., (OTCQB:IPIX) (“the Company”), a clinical stage biopharmaceutical company, today announces the closure of its Phase 2a clinical trial (see NCT03042702) of Kevetrin for the treatment of late-stage Ovarian Cancer (OC). The Company initiated the trial for the purpose of demonstrating modulation of the key tumor-suppressor protein p53, which was achieved in analysis of the first patients at the lowest dose of Kevetrin (see December 27, 2017 press release).
Throughout pre-clinical testing and two successful clinical trials, Kevetrin has demonstrated promising signs of efficacy as an anti-cancer agent and a favorable pharmacokinetic profile that includes a very short half-life and good bioavailability. It is believed that these characteristics make Kevetrin an ideal candidate for oral delivery (capsule or tablet), which will facilitate convenient and frequent dosing, perhaps even multiple times daily, to maximize the therapeutic benefit of the compound. With the positive observation of intra-tumor p53 modulation, the Company will now allocate resources to focus its efforts on completing development of an oral formulation, including performing bridging toxicology work.
The Company is adhering to a value-building strategy born from discussions with larger pharmaceutical companies interested in Kevetrin, one of the world’s most advanced p53 drug candidates. Securing the right development partner for Kevetrin remains an important objective.
“This study delivered multiple insights into how Kevetrin modulates the p53 protein and affects related molecular pathways,” commented Arthur P. Bertolino, MD, PhD, MBA, President and Chief Medical Officer at Innovation Pharmaceuticals. “Moreover, if we successfully transition to oral dosing of Kevetrin, we believe the therapeutic effect will be maximized, providing important benefits to cancer patients in need—beyond the ultimate convenience of oral delivery. An effective orally-delivered p53-modulating drug has the potential to transform cancer care and we are proud to be at the forefront toward achieving this goal.”
About Kevetrin and p53
Kevetrin is a small molecule that has demonstrated the potential of becoming a breakthrough cancer treatment by modulating p53, a protein frequently referred to as the “Guardian of the Genome” due to its critical role in controlling cell mutations. In the majority of cancers, and regardless of origin, type, and location, the p53 pathway is mutated, preventing the body from performing its natural anti-tumor functions. Conducted at Dana-Farber Cancer Institute and Beth Israel Deaconess Medical Center, a Phase 1 clinical trial (see NCT01664000) of Kevetrin in treating advanced solid tumors has been successfully completed, with patients showing good toleration and encouraging signs of potential therapeutic response (see ASCO 2015, ASCO 2013). Additional pre-clinical work supporting Kevetrin’s anti-cancer activity has recently been presented at scientific conferences (see EHA 2017, AACR 2017). The Company has initiated a Phase 2a trial of Kevetrin (see NCT03042702) in late stage, platinum-resistant/refractory ovarian cancer. Patients receive more frequent dosing (3 times per week) at higher levels and then receive standard of care treatment after trial conclusion. Efforts also are underway to develop Kevetrin as an oral anti-cancer agent that can be administered daily, potentially multiple times per day. The FDA has awarded Kevetrin Orphan Drug status for ovarian cancer, pancreatic cancer, and retinoblastoma, qualifying it for developmental incentives and a potential extra 7 years of market exclusivity upon drug approval. The FDA also has granted Kevetrin Rare Pediatric Disease designation for childhood retinoblastoma.

About the Company
Headquartered in Beverly, Massachusetts, Innovation Pharmaceuticals Inc. (IPI) 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, more recently, 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.
