Future Outlook

Aprea anticipates achieving short-term inflection points and catalysts, evaluating strategic partnerships, and releasing open label data for APR-1051 in H1 2025 and ATRN-119 in H2 2025. The company is financed into Q4 2025.

Management Comments

• The company is focused on developing best-in-class inhibitors for WEE1 and ATR.
• Management believes their technology is developed by pioneers in synthetic lethality.
• The company is evaluating optimal strategic partnerships.

Industry Context

Aprea is operating in the competitive oncology therapeutics space, focusing on DNA Damage Response pathways. The company's approach of using synthetic lethality and developing highly selective inhibitors aligns with current trends in precision oncology. The company is competing with other companies developing WEE1 and ATR inhibitors, such as AstraZeneca and Zentalis.

Comparison to Industry Standards

• AstraZeneca discontinued development of their WEE1 inhibitor, AZD-1775, due to tolerability issues, highlighting the need for improved safety profiles, which Aprea aims to address with APR-1051.
• Other ATR inhibitors, such as AZD6738 and BAY1895344, have shown hematological toxicities and intermittent dosing schedules, which Aprea is trying to overcome with the macrocyclic structure and continuous dosing of ATRN-119.
• Aprea's APR-1051 shows a greater than 150-fold difference in PLK1 inhibition compared to Zentalis's ZN-c3, suggesting a potentially better safety profile.
• Preclinical data for APR-1051 shows potentially favorable drug exposure compared to Zentalis's Azenosertib and AstraZeneca's Adavosertib.

Stakeholder Impact

• Shareholders may be impacted by the company's clinical trial results and financial performance.
• Employees are impacted by the company's ability to secure funding and advance its programs.
• Patients with advanced solid tumors may benefit from the development of new therapies.
• Potential partners may be impacted by the company's clinical data and strategic direction.

Next Steps

• Aprea will continue enrolling patients in the Phase 1 trials for APR-1051 and ATRN-119.
• The company will release open label data for APR-1051 in H1 2025.
• The company will release potential efficacy data for ATRN-119 in H2 2025.
• Aprea will evaluate optimal strategic partnerships.
