Pyxis Oncology Reports Financial Results for the Second Quarter Ended June 30, 2022 and Provides Pipeline Update

• Prioritized pipeline to focus on most advanced programs while maintaining financial flexibility to pursue business development opportunities

• Appointed Rachel Humphrey, M.D., a senior biotech executive with extensive experience in drug development, to its Board of Directors

• Cash balance of $207 million as of August 15, 2022 expected to provide runway through initial clinical value inflections for two lead pipeline programs

CAMBRIDGE, Mass., Aug. 15, 2022 (GLOBE NEWSWIRE) -- Pyxis Oncology, Inc. (Nasdaq: PYXS), a diversified oncology company focused on developing an arsenal of next-generation therapeutics to target difficult-to-treat cancers and improve quality of life for patients, today reported financial results for the second quarter and six months ended June 30, 2022 and provided a corporate update.

“Our strong balance sheet and cash runway will allow us to fund the Company through the second half of 2024, solidifying our position to potentially capitalize on multiple expected near-term catalysts and advance our programs to clinical development,” said Lara Sullivan, M.D., President and Chief Executive Officer of Pyxis Oncology. “We have elected to sharpen our near-term focus on the clinical execution of our two most advanced programs, anti-EDB Antibody Drug Conjugate (ADC), PYX-201, and anti-Siglec-15 monoclonal antibody (mAb), PYX-106. We also look forward to leveraging our team’s extensive industry network in identifying and facilitating opportunities where we can forge strategic partnerships to efficiently advance therapies that might change the treatment paradigm for patients with cancer.”

Corporate Development Highlights

  • Focus on advancing lead programs toward the clinic with near-term catalysts: Pyxis Oncology is on track to file Investigational New Drug applications (INDs) for PYX-201 and PYX-106 in 2022. Pyxis Oncology remains confident in the clinical and commercial opportunity for both programs based on the in vivo preclinical data to date and looks forward to working with the FDA to advance both programs into clinical development. PYX-201 is a novel, non-internalized ADC directed against a first-in-class target (EDB), which is selectively expressed in a large population of non-small cell lung cancer (NSCLC), breast cancer, and other solid tumors. PYX-106 is a potentially best-in-class mAb targeting Siglec-15, which has demonstrated over six-fold binding affinity for human Siglec-15 vs. prior attempts against this target.

  • Pausing development of anti-CD123 ADC, PYX-203, and anti-KLRG1 IO program, PYX-102: The Company will pause the preclinical development of PYX-203 and PYX-102. Pyxis Oncology remains optimistic about the long-term clinical promise of both assets and will consider both strategic collaboration and licensing opportunities and potential future in-house development to maximize value for both programs.

  • Ceasing development of anti-DLK1 ADC, PYX-202: On March 29, 2022, Pyxis Oncology disclosed it was conducting additional GLP and non-GLP toxicology studies on PYX-202, the ADC in-licensed from LegoChem Biosciences, to determine the clinical viability of the candidate. Upon review and analysis of the data, the Company has elected to stop the continued development of PYX-202. Preclinical data suggests DLK1 has the potential to be a novel therapeutic target in the treatment of small-cell lung cancer and soft tissue sarcoma. As LegoChem continues to work on the development of ADCs targeting DLK1 using its proprietary next generation payloads, Pyxis Oncology looks forward to leveraging its collaboration with LegoChem to evaluate the potential of these new candidate ADCs.

Jay Feingold, M.D., Ph.D., Chief Medical Officer of Pyxis Oncology, commented, “We believe that our therapeutic candidates have distinct advantages and are ideally suited for targeting difficult-to-treat tumors. PYX-201 represents a potentially first-in-class ADC with a novel mechanism of action, and PYX-106 has a differentiated activity profile with the potential to help patients who don’t respond or have stopped responding to current PD-1 targeted therapies. We look forward to progressing these two most advanced programs towards the clinic and filing INDs in the second half of this year.”

Addition to Board of Directors

Pyxis Oncology has appointed Rachel Humphrey, M.D., to its Board of Directors. Dr. Humphrey brings over 20 years of experience in oncology drug development and extensive experience in product development from pre-IND to commercialization of small molecules, cytotoxics and biologics in oncology and immuno-oncology. She currently serves as President and Chief Executive Officer of Normunity, an innovative immuno-oncology company. She was previously Chief Medical Officer at Black Diamond Therapeutics, a precision oncology medicine company, and was a member of the Board of Directors at Xilio Therapeutics. Prior to that, she served as Chief Medical Officer and a member of the Board of Directors of CytomX Therapeutics, a clinical stage oncology company, where she was responsible for the clinical development of Probody™ Therapeutics for the treatment of cancer. She oversaw the early and late-stage clinical development of two new oncology molecular entities, ipilimumab (Yervoy®) while serving as Vice President, Clinical Development at Bristol-Myers Squibb, and sorafenib (Nexavar®) at Bayer.

Dr. Sullivan commented, “We are excited to welcome Rachel to our Board of Directors. Her experience and successful track record in oncology drug development spanning across large pharmaceutical and small biotechnology companies will add incredible value to our already deep bench of industry leaders as we near the clinic with two promising oncology therapeutic candidates.”

Financial Update for Quarter Ended June 30, 2022

  • Pyxis Oncology had cash and cash equivalents of $223 million as of June 30, 2022, and approximately $207 million (preliminary, unaudited) as of August 15, 2022, which is expected to fund operations through the second half of 2024.
  • Research and development expenses were $17.2 million for the three months ended June 30, 2022, compared to $3.2 million for the three months ended June 30, 2021. The increase was primarily due to increased expenses associated with contract manufacturing of drug products and drug substance, preclinical cost related to toxicity studies and an increase in employee headcount to support research and development activities.
  • General and administrative expenses were $8.6 million for the three months ended June 30, 2022, compared to $2.7 million for the three months ended June 30, 2021. The increase was primarily due to higher personnel-related expenses (including stock-based compensation), increases in legal and professional fees, rent, and directors and officers insurance expense to support our growth and operations.
  • Net loss was $25.6 million, or $(0.79) per common share, for the three months ended June 30, 2022, compared to $8.1 million, or $(5.54) per common share, for the three months ended June 30, 2021. Net loss for the three months ended June 30, 2022 and 2021 included $4.0 million and $0.6 million, respectively, related to non-cash stock-based compensation expense.
  • As of August 15, 2022, the outstanding number of shares of Common Stock of Pyxis Oncology was 32,834,561.
