• The combined company will have a strong investor base, including both new and existing investors.
• The combined company will have a clear focus on a promising clinical-stage asset with potential in multiple inflammatory indications.

Negatives

• The merger is subject to customary closing conditions, including shareholder approval, which could delay or prevent the transaction from closing.
• The combined company will need to successfully execute its development plan for IMG-007, which is subject to clinical and regulatory risks.
• The combined company will need to raise additional capital to continue to advance its pipeline beyond the initial funding from the private placement.

Risks

Management Comments

• We believe IMG-007 has the potential to be extremely impactful for patients with inflammatory diseases, while also building value for our shareholders.
• We are well-positioned to advance IMG-007 development and look forward to executing our development plan in atopic dermatitis and potentially additional indications.

Industry Context

The merger reflects a trend in the biopharmaceutical industry of companies combining resources to advance promising clinical-stage assets. The focus on IMG-007, a monoclonal antibody targeting OX40, aligns with the growing interest in immunomodulatory therapies for inflammatory diseases.

Comparison to Industry Standards

• IMG-007 is a monoclonal antibody (mAb) targeting OX40, a costimulatory receptor that presents primarily on activated T cells, which is a similar target to other mAbs in development for atopic dermatitis.
• IMG-007 has a longer half-life compared to other OX40-targeting mAbs in Phase 2 and later development, enabling its potential for dose and schedule optimization.
• IMG-007 has silenced antibody dependent cellular cytotoxicity (ADCC) function, and is non-T cell depleting, leading to a potentially improved tolerability profile relative to other mAbs in the class.
• IMG-007s Phase 2a clinical trial in atopic dermatitis demonstrated marked and durable clinical activity and well-tolerated safety profile, which is comparable to other mAbs in development for atopic dermatitis.
• The planned Phase 2b clinical trial in atopic dermatitis for IMG-007 is a standard next step in the development of a new drug candidate.
