PYX-106

- Preliminary data from the Phase 1 trial of PYX-201 remains on track to be announced in the fall of 2024 - Preliminary data from the Phase 1 trial of PYX-106 is expected to be reported by year-end 2024 - Expected cash runway into 2H 2026 BOSTON, Aug. 14, 2024 (GLOBE NEWSWIRE) -- Pyxis Oncology, Inc. (Nasdaq: PYXS), a clinical stage company focused on developing next generation therapeutics to target difficult-to-treat cancers, today reported financial results for the second quarter ended June 30, 2024, and provided a corporate update. The Company ended the second quarter of 2024 with $157.2 million in cash, cash equivalents, restricted cash and short-term investments, which is expected to provide cash runway into the second half of 2026 and enable the Company to fund the next phase of PYX-201 clinical development, which the Company plans to announce in the fall of 2024. "I'm thrilled with our team's continued operational and clinical execution prowess that keeps us on track to deliver preliminary data from our ongoing Phase 1 trial of PYX-201, a first-in-concept tumor stroma targeting antibody-drug conjugate (ADC) against the stromal Extradomain-B Fibronectin (EDB+FN) target, this fall," said Lara S. Sullivan, M.D., President and Chief Executive Officer of Pyxis Oncology. Dr. Sullivan added, "To date, we have dosed 72 subjects in the PYX-201 dose escalation study with a continued focus on head and neck squamous cell carcinoma (HNSCC), non-small cell lung cancer (NSCLC), ovarian cancer, soft tissue sarcoma, and pancreatic ductal adenocarcinoma cancer (PDAC) based on an assessment of factors including immunohistochemistry target expression, stromal volume, unmet medical need, and clinical investigator judgment. PYX-201 safety data observed to date continues to support go-forward monotherapy and potential combination clinical development strategies, both of which we believe could have the potential to provide additional treatment options to patients with difficult-to treat-cancers.” Recent Clinical Program Updates PYX-201 PYX-201, an ADC that uniquely targets EDB+FN within the tumor stroma, is the Company’s lead clinical program being evaluated in an ongoing Phase 1 trial in multiple types of solid tumors. To date, 72 subjects have been dosed with PYX-201 in this Phase 1 trial. Dose escalation and safety monitoring remain ongoing for the trial.The Company expects to announce preliminary data from the Phase 1 trial of PYX-201, including efficacy, safety, pharmacokinetics (PK), and provide an update on future development plans in the fall of 2024. 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 ongoing Phase 1 clinical studies in multiple types of solid tumors. Dose escalation of PYX-106 and safety monitoring is ongoing with 33 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. Second Quarter 2024 Financial Results As of June 30, 2024, Pyxis Oncology had cash and cash equivalents, including restricted cash and short-term investments of $157.2 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, including the Company’s current projections for PYX-201's next phase of clinical development.Research and development expenses were $13.9 million for the quarter ended June 30, 2024, compared to $11.4 million for the quarter ended June 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 $6.1 million for the quarter ended June 30, 2024, compared to $6.7 million for the quarter ended June 30, 2023. The period-over-period decline was primarily due to lower professional and consultant fees.Net loss was $17.3 million, or ($0.29) per common share, for the quarter ended June 30, 2024, compared to $15.9 million, or ($0.41) per common share, for the quarter ended June 30, 2023. Net losses for the quarters ended June 30, 2024 and 2023 included $2.9 million and $3.7 million, respectively, related to non-cash stock-based compensation expense.As of August 14, 2024, the outstanding number of shares of common stock of Pyxis Oncology was 58,942,243.
