Management Comments

• Lara S. Sullivan, M.D., President and Chief Executive Officer of Pyxis Oncology, stated that the encouraging PYX-201 safety profile likely reflects the specificity of target expression within tumor tissue.
• Dr. Sullivan also mentioned that the tumor stroma is a prominent component of many solid tumors, and PYX-201 could have broad utility in many cancer settings.

Industry Context

Pyxis Oncology is operating in the competitive field of oncology therapeutics, focusing on antibody-drug conjugates and immuno-oncology. The company's approach of targeting the tumor stroma with PYX-201 is a novel strategy that could differentiate it from competitors. The development of PYX-106, targeting Siglec-15, also aligns with the industry's focus on novel immune checkpoint inhibitors.

Comparison to Industry Standards

• The company's approach of targeting the tumor stroma with PYX-201 is a novel strategy compared to traditional ADCs that target cell surface antigens, such as Kadcyla (HER-2), Enhertu (HER-2), Padcev (Nectin-4), Elahere (FRa), Tivdak (TF), and Trodelvy (TROP-2).
• The company's PYX-201 ADC has been designed with technical improvements such as engineered cysteine residues for a target DAR of 4, an optimized val-cit linker, and an optimized auristatin payload (AUR-0101), which are designed to improve tolerability and stability compared to traditional val-cit-MMAE ADCs like Adcetris and Padcev.
• Preclinical studies of PYX-201 have shown enhanced tolerability in non-human primates at 10-12 mg/kg compared to approved older generation val-cit-MMAE ADCs at 3 mg/kg, suggesting a potential for a wider therapeutic index.
• PYX-106 is a fully human antibody targeting Siglec-15, which is a differentiated approach compared to other immuno-oncology therapies that target PD-(L)1 or CTLA-4. PYX-106 has shown 10-fold higher affinity to human Siglec-15 than a benchmark in development.

Stakeholder Impact

• Shareholders will be impacted by the company's financial performance and clinical trial results.
• Employees will be impacted by the company's ability to fund operations and continue development programs.
• Patients may benefit from the development of new cancer therapeutics.
• Creditors will be impacted by the company's financial stability and ability to repay debts.

Next Steps

• Pyxis Oncology plans to report preliminary Phase 1 data for PYX-201 in the fall of 2024.
• The company plans to report preliminary Phase 1 data for PYX-106 in the second half of 2024.
• The company will continue to enroll patients in its ongoing Phase 1 clinical trials for PYX-201 and PYX-106.
