Executive summary

  • Focused on developing targeted radiotherapeutics for CNS cancers, with lead candidate REYOBIQ advancing in multiple clinical trials and positive Phase 1 results in leptomeningeal metastases.

  • Achieved US market introduction of CNSide CSF diagnostics platform, securing first national coverage with UnitedHealthcare and CMS CLIA certification for the Houston lab.

  • Expanded commercial team and leadership to support CNSide scale-up and research initiatives.

  • Received significant grant funding, including a $17.6M CPRIT grant and a $3M DoD award, supporting clinical development and expansion into pediatric brain cancer trials.

  • Achieved compliance with Nasdaq equity listing requirements after a period of risk, but remains under panel monitoring and faces ongoing minimum bid price compliance challenges.

Financial highlights

  • Net loss of $4.4M for Q3 2025 and $16.7M for the nine months ended September 30, 2025, compared to $2.9M and $9.1M losses in the same periods of 2024.

  • Cash and investments rose to $16.6M at September 30, 2025, from $76K at December 31, 2024, driven by equity financings.

  • Grant revenue recognized was $1.4M for Q3 and $3.8M for the nine months, down from $1.5M and $4.4M in 2024.

  • Working capital improved to $4.0M at September 30, 2025, from a deficit of $10.3M at year-end 2024.

  • Q3 2025 operating loss was $4.5M, mainly due to higher compensation and professional fees.

Outlook and guidance

  • Expects R&D and G&A expenses to increase in the remainder of 2025 as clinical trials expand and the CNSide Test launches.

  • Plans to begin enrollment in the RESPECT-PBC pediatric brain cancer trial before year-end 2025.

  • Plans to expand commercial footprint for CNSide, clarify pivotal plan for REYOBIQ with the FDA, and strengthen financial position in capital markets in Q4 2025.

  • Initial CNSide commercial focus targets National Cancer Institute Designated Cancer Centers.

  • Ongoing need to raise additional capital to fund operations and clinical programs; inability to do so would materially impact operations.

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.
