BOSTON, May 30, 2023 (GLOBE NEWSWIRE) -- Pyxis Oncology, Inc. (Nasdaq: PYXS), a clinical-stage company focused on developing next-generation therapeutics to target difficult-to-treat cancers, today announced dosing of the first subject in the Phase 1 trial of PYX-106. PYX-106 is a fully human immunotherapy antibody candidate that is designed to block the activity of Siglec-15, an immune suppressor expressed across a broad range of tumors. The Company also announced that the second dose level has been initiated in the ongoing Phase 1 trial of PYX-201, a novel antibody-drug conjugate (ADC) product candidate licensed from Pfizer targeting extradomain-B (EDB) of fibronectin, a non-internalizing antigen that is an integral component of the extracellular matrix in tumors.
“We are excited to announce dosing of the first subject in the Phase 1 trial of PYX-106 and we are enthusiastic about the potential PYX-106 may hold for patients, particularly those not well served by currently available immunotherapies,” said Lara S. Sullivan, M.D., President and Chief Executive Officer of Pyxis Oncology. “We expect to see preliminary data from each of our ongoing Phase 1 trials of PYX-106 and PYX-201, including biomarker results and potential early signs of clinical activity, in the late-2023 to early-2024 timeframe.”
