Executive summary

  • Focused on advancing the proposed merger with Cullgen, with ongoing efforts to secure regulatory approval from the China Securities Regulatory Commission and Nasdaq for the transaction.

  • Waived the "No Solicitation" clause in the merger agreement to allow both parties to explore alternative transactions while pursuing merger approval.

  • Actively seeking to license or monetize its iSPERSE™ technology and related clinical programs, including a Phase 2-ready acute migraine asset.

Financial highlights

  • Revenues fell to nil for the year ended December 31, 2025, from $7.8 million in 2024, reflecting the wind down of the PUR1900 program.

  • Research and development expenses dropped to less than $0.1 million in 2025 from $7.2 million in 2024, due to program wind down and cost reductions.

  • General and administrative expenses decreased to $5.1 million in 2025 from $7.8 million in 2024, mainly from lower employment and operating costs.

  • Net loss narrowed to $5.2 million in 2025 from $9.6 million in 2024.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
