RedHill's Opaganib Selected for Evaluation by BARDA and NIH Countermeasures Programs

Insights
The selection of opaganib for evaluation by the U.S. government's Chem MCM Program and CCRP signifies a strategic move into a niche but critical area of biodefense. The drug's potential to serve as a countermeasure against Sulfur Mustard, a chemical warfare agent, aligns with national security interests and public health preparedness. This development could lead to increased funding and support for RedHill Biopharma, as government contracts for MCMs typically involve substantial investment.
Furthermore, the dual utility of opaganib, already under consideration for Acute Radiation Syndrome, suggests cost-effectiveness in research and development. This could enhance investor confidence in RedHill's portfolio diversification and its ability to manage regulatory pathways. However, it is essential to monitor the FDA's stance, as approval is a pivotal milestone that would directly influence the stock's performance. The company's ability to navigate the complex regulatory environment will be crucial for its valuation.
Opaganib's role as an SPHK2 inhibitor places it at the forefront of targeted therapies in sphingolipid metabolism, a pathway implicated in various pathological conditions. Its evaluation for chemical countermeasures introduces a new application outside of its current indications, which include COVID-19, ARDS and oncology. The versatility of opaganib may reflect positively on RedHill's research capabilities and its potential for pipeline expansion.
It is noteworthy that the efficacy of opaganib against sub-chronic fibrosis and ARDS due to Sulfur Mustard will be assessed. These conditions represent significant challenges in chemical injury management and a successful countermeasure could lead to substantial demand within military and strategic stockpiles. The long-term implications for RedHill Biopharma hinge on successful clinical outcomes that demonstrate efficacy and safety in these new indications.
RedHill Biopharma's stock (Nasdaq: RDHL) may experience increased volatility following this announcement due to anticipated government contracts and the potential broadening of opaganib's market. The financial implications of entering the biodefense space are substantial, considering the long-term revenue streams from government stockpiling and the possibility of exclusivity in supply contracts. Investors should consider the historical performance of biotech firms engaged in MCM development, which often sees an uptick in valuation upon positive trial outcomes and government endorsements.
However, the inherent risks of drug development, especially in a high-stakes area such as biodefense, must be weighed against the potential returns. The cost of clinical trials and the uncertainty of FDA approval present financial risks that could impact short-term liquidity and long-term profitability. Stakeholders should keep an eye on RedHill's financial health, R&D expenditure and cash flow to assess the sustainability of its business model in light of these new developments.

Sulfur Mustard is a powerful alkylating chemical warfare agent. Exposure to Sulfur Mustard causes extensive skin blistering and severe injury to the eyes, lungs, and multiple organs, causing potentially fatal damage. Primarily affecting the lungs, Sulfur Mustard poisoning can result in symptoms such as acute lung injury, acute respiratory distress syndrome, bronchiolitis obliterans, fibrosis, and subsequent associated infections.
"With the alarming increase in global geo-political instability, the opportunity to evaluate opaganib as a potential vital protective agent against chemical attack is inspiring. We, and our development partner, Apogee Biotechnology Corporation, are delighted to partner with the NIH/NIAID, ASPR/BARDA, and Battelle in our efforts to make a significant difference in this area of huge medical and societal need," said Dror Ben-Asher, RedHill's Chief Executive Officer.

About Opaganib (ABC294640)
Opaganib, a proprietary investigational host-directed and potentially broad-acting drug, is a first-in-class, orally administered sphingosine kinase-2 (SPHK2) selective inhibitor with anticancer, anti-inflammatory and antiviral activity, targeting multiple potential diseases, including gastrointestinal acute radiation syndrome (GI-ARS), COVID-19, other viruses as part of pandemic preparedness, and cholangiocarcinoma (bile duct cancer).
Opaganib's host-directed action is thought to work through the inhibition of multiple pathways, the induction of autophagy and apoptosis, and disruption of viral replication, through simultaneous inhibition of three sphingolipid-metabolizing enzymes in human cells (SPHK2, DES1 and GCS).
Opaganib was selected by the
Opaganib has demonstrated antiviral activity against SARS-CoV-2, multiple variants, and several other viruses, such as Influenza A. Opaganib also recently demonstrated a distinct synergistic effect when combined individually with remdesivir (Veklury®, Gilead Sciences Inc., Nasdaq: GILD), significantly improving potency while maintaining cell viability, in a
Being host-targeted, and based on data accumulated to date, opaganib is expected to maintain effect against emerging viral variants. In prespecified analyses of Phase 2/3 clinical data in hospitalized patients with moderate to severe COVID-19, oral opaganib demonstrated improved viral RNA clearance, faster time to recovery and significant mortality reduction in key patient subpopulations versus placebo on top of standard of care. Opaganib has demonstrated its safety and tolerability profile in more than 470 people in multiple clinical studies and expanded access use. Data from the opaganib global Phase 2/3 study was published in medRxiv.
Opaganib has received Orphan Drug designation from the FDA for the treatment of cholangiocarcinoma and has undergone studies in advanced cholangiocarcinoma (Phase 2a) and prostate cancer. Opaganib also has a Phase 1 chemoradiotherapy study protocol ready for FDA-IND submission.
Opaganib has also shown positive preclinical results in renal fibrosis, and has the potential to target multiple oncology, radioprotection, viral, inflammatory, and gastrointestinal indications.
