WAKEFIELD, MA / ACCESSWIRE / July 22, 2022 / Innovation Pharmaceuticals (OTCQB:IPIX) ("the Company"), a clinical stage biopharmaceutical company, today provided an update on the Company's Brilacidin program in Oral Mucositis (OM). Brilacidin, delivered as an oral rinse, was shown in Phase 2 clinical testing (NCT02324335) to reduce incidence, delay onset and decrease duration of severe OM (WHO Grade ≥ 3) in Head and Neck Cancer (HNC) patients receiving chemoradiation. The Company and FDA have completed an End-of-Phase 2 meeting and agreed to an acceptable Phase 3 program.

To assess current insurance programs and Brilacidin's overall commercialization potential in OM, the Company engaged separate consulting firms to analyze the provider and payer landscape -- specifically, the likelihood of clinicians to prescribe and insurers to reimburse a novel OM treatment, such as Brilacidin, should it eventually gain marketing approval. Results of this analysis are summarized below.

• Large Unmet Need: Oral Mucositis (OM) presents a significant socioeconomic cost to the healthcare system and to patients, as it can substantially impact quality of life, result in hospitalization, and lead to disruptions in anti-cancer therapy and poorer outcomes. Current standard of care (SOC) treatment options (primarily devices) are lacking because they only act as symptom management and do not decrease incidence of severe OM (SOM).
• Competitive Positioning: Brilacidin's oral sachet formulation was perceived as convenient and highly preferred by key opinion leaders (KOLs) in comparison to intravenous (IV) options, and KOLs are willing to prescribe Brilacidin for all HNC patients because the compound's preventative properties and ease of use as an oral rinse. Brilacidin has the potential to be a first-line product for prevention and treatment of SOM due to efficacy perceived as being highly clinically meaningful.
• Development Considerations: KOLs viewed the primary endpoint of reducing SOM incidence as favorable, though recommend additional secondary endpoints to promote greater uptake (i.e., reduction of opioid usage, overall pain level, and time to onset of SOM). Maximizing overall efficacy (reduction of SOM) was identified as a higher KOL priority than the specific mechanism of action (anti-inflammatory activity) by which efficacy is achieved.
• Coverage Perspectives: Developing Brilacidin as a New Drug Application (NDA), via the 505(b)(1) pathway, significantly improves Brilacidin's commercialization prospects in the OM therapeutic area. OM products, such as MuGard, GelClair, Episil, and Caphosol, which were developed as devices and not drugs, have struggled to show clinical benefit, as they are primarily palliative in nature, and from a government payer perspective are not covered under Medicare Part D.
• Reimbursement Landscape: At least 2 approved drugs in all therapeutic drug classes must be made available under Medicare Part D, per USP Medicare Model Guidelines. The guidelines establish the framework (the rules) that drive payer formularies. Given there are no approved drugs for OM in HNC, should Brilacidin be approved, it is highly likely it would be included in payer formularies as a pharmacy benefit.
• Commercial Opportunity: Annually, in the U.S., Brilacidin has the potential to address 52,000 OM patients in HNC, with potential future extension to 20,000 OM patients in Hematopoietic Stem Cell Transplantation (HSCT), and 160,000 OM patients in all chemotherapy categories. Based on physician estimates of Brilacidin adoption and other pricing-based assumptions, forecasts of U.S. annual sales are $188 million for OM in HNC patients in 2030, with a potential additional upside of $106 million for OM in HSCT and $598 million for OM in all chemotherapy categories.

"This analysis reinforces Brilacidin's potential to become a breakthrough OM treatment and commercialization success," said Leo Ehrlich, Chief Executive Officer at Innovation Pharmaceuticals. "While our focus on Brilacidin over the last few years has been in the antiviral space, given COVID-19, we have made meaningful strides to advance Brilacidin in OM, including refinement of the oral rinse formulation in sachet form. We continue to pursue partnering opportunities so Brilacidin can be further advanced in oral mucositis in the clinic."

About Oral Mucositis

Oral Mucositis (OM) is a painful and debilitating complication of chemoradiation.¹ Head and Neck Cancer (HNC) patients, comprising an estimated 66,000 newly diagnosed cases in the U.S. in 2021², and an estimated 900,000 worldwide³, are at high risk of developing OM. By 2030, the global incidence of HNC cases is expected to exceed 1 million per year. Moreover, between 25 and 60 percent of cancer patients, regardless of cancer type, also will experience OM. Characterized by inflammation and ulceration, patients suffering from OM are often unable to speak and eat (requiring the insertion of a feeding tube) and are more susceptible to infections, with severe cases leading to hospitalization at increased treatment costs of up to $25,000. There currently are no approved medications for the prevention of OM in the HNC population, with only limited palliative care options available. Worldwide, the OM market was estimated to be $1.5bn in 2021.⁴
