- Registration Rights: Aileron agreed to file a resale registration statement within 90 days of the financing closing and use commercially reasonable efforts to have it declared effective within 30 days thereafter.
- Risks: The filing highlights risks related to the sufficiency of cash resources, the ability to obtain stockholder approval for the conversion of preferred stock, clinical trial outcomes, and regulatory approvals. The company disclaims any obligation to update forward-looking statements.
