Recent Clinical Program Updates

PYX-201

PYX-201 is an antibody-drug conjugate (ADC) that is designed to uniquely target Extradomain-B Fibronectin (EDB+FN), which is believed to be a key structural component of the tumor extracellular matrix. PYX-201 is the Company’s lead clinical program being evaluated in an ongoing Phase 1 trial in multiple types of solid tumors.

• To date, 80 subjects have been dosed with PYX-201 in this Phase 1 trial. Dose escalation and safety monitoring remain ongoing for the trial.
  
• The Company will present preliminary data from the Phase 1 dose escalation trial of PYX-201, including efficacy, safety, and pharmacokinetics (PK). The Company will provide an update on future development plans at a Company hosted investor event in New York City on Wednesday, November 20, 2024, at 4:30 p.m. ET. Additional information about the event can be found here.
  

PYX-106

PYX-106, a fully human Siglec-15-targeting antibody designed to block suppression of T-cell proliferation and function, is being evaluated in an ongoing Phase 1 clinical study in multiple types of solid tumors.

• Dose escalation of PYX-106 and safety monitoring is ongoing with 45 subjects dosed to date in the Phase 1 trial.
  
• The Company expects to report preliminary data from the Phase 1 trial of PYX-106, including PK/pharmacodynamic results, by year-end 2024.
  

Third Quarter 2024 Financial Results 

• As of September 30, 2024, Pyxis Oncology had cash and cash equivalents, including restricted cash and short-term investments of $146.3 million. The Company believes that its current cash, cash equivalents, and short-term investments will be sufficient to fund its operations into the second half of 2026.
  
• Research and development expenses were $17.7 million for the quarter ended September 30, 2024, compared to $14.7 million for the quarter ended September 30, 2023. The period-over-period increase was primarily due to increased clinical trial-related expenses, including manufacturing of drug product and drug substance for our ongoing Phase 1 clinical trials of PYX-201 and PYX-106.
  
• General and administrative expenses were $6.0 million for the quarter ended September 30, 2024, compared to $10.7 million for the quarter ended September 30, 2023. The period-over-period decline was primarily due to lower legal, professional and consulting fees.
  
• Net loss was $21.2 million, or ($0.35) per common share, for the quarter ended September 30, 2024, compared to $23.0 million, or ($0.56) per common share, for the quarter ended September 30, 2023. Net losses for the quarters ended September 30, 2024, and 2023 included $3.0 million and $5.2 million, respectively, related to non-cash stock-based compensation expense.
  
• As of November 12, 2024, the outstanding number of shares of common stock of Pyxis Oncology was 59,465,729.
