Island Pharmaceuticals has confirmed the material significance of recent FDA feedback on its Galidesivir development pathway and addressed ASX queries on disclosure timing and capital raising activities.
- FDA feedback deemed material to share price and regulatory progress
- Trading halt requested to manage disclosure and market orderliness
- Unintentional breach of ASX Listing Rule 15.7 during capital raising
- $9 million placement secured to fund Galidesivir development
- Company affirms compliance with continuous disclosure obligations
Background and FDA Feedback
Island Pharmaceuticals Limited (ASX – ILA) has provided detailed responses to the Australian Securities Exchange (ASX) following an Aware Letter concerning its disclosure of feedback from the US Food & Drug Administration (FDA) on its antiviral candidate Galidesivir. The FDA feedback, received on 30 January 2026, confirmed the validity of Island’s proposed animal model under the Animal Rule, a regulatory pathway allowing drug approval based on animal efficacy data when human trials are not feasible.
This feedback was described by Island as highly constructive and strategically important, providing clarity on key components such as the Angola strain of Marburg virus, the cynomolgus macaque model, and viral challenge dose. The company views this as a major de-risking milestone for Galidesivir’s development.
Disclosure and Trading Halt
Island acknowledged that the FDA feedback was material information likely to affect the price or value of its securities. The company requested a trading halt on 2 February 2026 to manage its disclosure obligations and maintain orderly trading while preparing its announcement, which was released on 4 February 2026. The halt was deemed necessary as Island required time to obtain expert regulatory advice to fully understand the technical feedback before public release.
During this period, the information was confined to the board and external regulatory advisors under confidentiality. Island confirmed no unusual trading activity was observed prior to the announcement.
Capital Raising and Compliance Issues
Following the FDA feedback, Island secured firm commitments for a $9 million placement to advance Galidesivir’s US biodefence opportunity. The placement, announced concurrently with the FDA update, involved issuing over 25 million new shares at $0.35 each, attracting local and international institutional investors, including a US-based family office.
Island disclosed that some information about the FDA feedback was shared with its corporate advisor, Ora Capital, and certain investors during the trading halt under wall-crossing arrangements. However, the company admitted this was not strictly compliant with ASX Listing Rule 15.7, which prohibits releasing market-sensitive information before it is publicly disclosed. Island described this breach as unintentional and has since reinforced its continuous disclosure policies internally.
Regulatory and Market Implications
Island confirmed it is currently in compliance with ASX Listing Rules, including continuous disclosure obligations. The FDA’s confirmation of the Animal Rule pathway provides a clearly defined route to regulatory approval, which is critical for Galidesivir’s commercial prospects. The $9 million capital raise ensures the company is funded to progress without delay, signalling confidence in the program’s potential.
Market reaction was positive, with Island’s share price rising from $0.39 before the announcement to a high of $0.495 afterward, reflecting investor optimism about the de-risked development pathway and fresh funding.
Bottom Line?
Island Pharmaceuticals’ next steps will be closely watched as it advances Galidesivir under a clarified regulatory pathway, with funding now secured but compliance lessons learned.
Questions in the middle?
- How will the FDA feedback influence the timeline for Galidesivir’s final approval?
- What measures will Island implement to prevent future disclosure compliance lapses?
- How will the new capital be allocated across clinical development and regulatory milestones?
