Future Outlook

Management Comments

• Management expects to continue to incur additional substantial losses in the foreseeable future as a result of the Company's research and development and other operational activities.

Industry Context

The announcement reflects the ongoing trend of pharmaceutical companies collaborating to develop novel therapies, particularly in oncology. The licensing agreement with Ipsen highlights the value of Sutro's technology platform and its potential to generate revenue through partnerships. The increased R&D spending is consistent with the high costs associated with clinical-stage drug development.

Comparison to Industry Standards

• Sutro's increased R&D spending is typical for a clinical-stage biotech company advancing multiple programs.
• The company's collaboration revenue is comparable to other biotech companies with similar partnership strategies.
• The net loss is consistent with the financial profile of a company that is still in the development phase and not yet generating revenue from product sales.
• The licensing agreement with Ipsen is a significant milestone, similar to other biotech companies that have successfully partnered with larger pharmaceutical companies to advance their product candidates.
• The company's cash position is relatively strong, providing a runway for continued operations and development.

Stakeholder Impact

• Shareholders may be concerned about the increased net loss and the need for additional capital.
• Employees may be affected by potential changes in operations and resource allocation.
• Customers (collaborators) will benefit from the continued development of product candidates.
• Suppliers may see increased demand for their services and materials.
• Creditors may be concerned about the company's financial performance and future funding needs.

Next Steps

• Continue enrollment in the REFRME-O1 study.
• Initiate the Phase 2 study for luvelta in NSCLC in the second half of 2024.
• Begin enrollment of a registration-directed trial of luvelta for treatment of pediatric RAM phenotype AML in the second half of 2024.
• File an IND for STRO-004 in 2025.
