About SRF114

SRF114 is a fully human, afucosylated anti-CCR8 antibody designed to preferentially deplete CCR8+ Treg cells within the tumor microenvironment. In preclinical studies, Surface Oncology has shown that SRF114 induces antibody-dependent cellular cytotoxicity (ADCC) and/or antibody-dependent cellular phagocytosis (ADCP) pathways to deplete intratumoral Treg cells. In addition, SRF114 reduced tumor growth in murine models. These findings support the advancement of SRF114 as a therapeutic candidate that holds the potential to drive anti-tumor immunity in patients.

Pyxis Oncology Announces Dosing of First Subject in Phase 1 Trial of PYX-201, a Novel ADC for Solid Tumors

On March 16, 2023 Pyxis Oncology, Inc. (Nasdaq: PYXS), a clinical-stage company focused on developing next-generation therapeutics to target difficult-to-treat cancers, reported dosing of the first subject in a Phase 1 trial of PYX-201 (Press release, Pyxis Oncology, MAR 16, 2023, View Source [SID1234628912]). PYX-201 is 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. EDB fibronectin is overexpressed in many solid tumors and minimally expressed in most normal adult tissues. The Company anticipates preliminary data from this trial in early 2024.

"PYX-201 has the potential to offer a new approach to targeting multiple tumor types via a multipronged mechanism of action that may benefit patients with solid tumors. We expect to see preliminary data from this study, including biomarker results and potential early signs of clinical activity, in early 2024," said Lara S. Sullivan, M.D., President and Chief Executive Officer of Pyxis Oncology. "I’m proud of the work done by the Pyxis Oncology team to initiate dosing in our first clinical trial. Dosing is a significant achievement and important milestone that marks the transition of Pyxis Oncology to a clinical-stage company."

Alexander Spira, M.D., Director NEXT Oncology Virginia, Co-Director, VCS Research Institute, and Director, Thoracic and Phase I Program and Clinical Assistant Professor at Johns Hopkins University, said, "We are always looking for potential new treatments for patients who have limited or no options available. I am particularly excited about PYX-201 because it was designed to offer several important safety and efficacy improvements compared to traditional ADCs, and we look forward to evaluating it in this Phase 1 study."

The Phase 1 trial, referred to as PYX-201-101, is an open-label, multicenter, dose-escalation trial designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary efficacy of PYX-201 and identify recommended doses for further study. Patients with relapsed or refractory solid tumors, including non-small cell lung cancer (NSCLC), hormone receptor-positive breast cancer, ovarian cancer, thyroid cancer, pancreatic ductal adenocarcinoma, soft tissue sarcoma, hepatocellular carcinoma or kidney cancer are eligible to enroll.

Jay Feingold, M.D., Ph.D., Chief Medical Officer of Pyxis Oncology, said, "ADCs are important tools in the cancer treatment armamentarium, and further ADC development may represent a significant opportunity to address several solid tumor types with significant unmet need."

Jan Pinkas, Ph.D., Chief Scientific Officer of Pyxis Oncology, added, "Unlike traditional ADCs, PYX-201 acts via three distinct mechanisms to comprehensively target tumors independent of cell surface marker expression. Once PYX-201 binds to EDB fibronectin in the tumor stroma, a potent auristatin-derived payload is cleaved and diffuses across adjacent tumor cell membranes and surrounding supportive tumor infrastructures, including fibroblasts and tumor vasculature. PYX-201 also acts via a bystander effect in the tumor microenvironment as aur0101 payload is recycled and re-released, directly killing adjacent tumor cells. Finally, PYX-201 also stimulates anti-tumor immunogenic activity by promoting dendritic cell maturation and inducing immunogenic cell death, which could provide a rationale for the evaluation of combination-based approaches with immuno-oncology products, including checkpoint inhibitors."
About the Flexible Antibody Conjugation Technology (FACT) Platform

The FACT platform, licensed from Pfizer, Inc. in 2021, is designed to facilitate creation of next-generation ADCs like PYX-201 that have the potential for improved anti-tumor activity, safety and tolerability. Compared to traditional ADC approaches, the FACT platform is based upon technical improvements to allow site-specific payload conjugation, linker stability and payload potency.

About PYX-201-101

PYX-201-101 (NCT05720117) is an open-label, multicenter, Phase 1 dose-escalation trial designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of PYX-201. Patients with relapsed or refractory solid tumors known to have significant expression of EDB of fibronectin, including with relapsed or refractory solid tumors, including non-small cell lung cancer, hormone receptor positive breast cancer, ovarian cancer, thyroid cancer, pancreatic ductal adenocarcinoma, soft tissue sarcoma, hepatocellular carcinoma or kidney cancer are eligible to enroll.

Purple Biotech Reports Biomarker Data from CM24 Phase 1 Dose Escalation Study

On March 16, 2023 Purple Biotech Ltd. ("Purple Biotech", or the "Company") (NASDAQ/TASE: PPBT), a clinical-stage company developing first-in-class, effective and durable therapies that harness the power of the tumor microenvironment (TME) to overcome tumor immune evasion and drug resistance, reported its new results from exploratory analyses conducted as part of a Phase 1 dose escalation study that assessed the safety and tolerability of CM24 plus nivolumab (NCT04731467) (Press release, Purple Biotech, MAR 16, 2023, View Source [SID1234628911]). The study enrolled 14 patients with advanced cancers including 11 patients with pancreatic adenocarcinoma (PDAC), two patients with colorectal adenocarcinoma (CRC) and one patient with papillary thyroid cancer. The analyses conducted in eight evaluable PDAC patients demonstrate clinically meaningful and durable reductions in serum myeloperoxidase, a biomarker for NETs, following treatment with CM24 plus nivolumab, immediately and 15 days after the first administration. In addition, analyses of tumor samples derived from the evaluable PDAC patients suggest that patient survival may be positively associated with higher levels of CEACAM1+ tumor-infiltrating lymphocytes in the TME. These results, along with additional data from this clinical study, are part of the Company’s effort aimed at identifying and evaluating the potential utility of a biomarker to optimize patient selection and treatment. Further study results on this topic will be presented at an upcoming medical conference.

NETs are web-like DNA structures and are covered with cancer-promoting proteins that are released by activated neutrophils and that have been shown to engulf tumors and promote immune evasion, tumor progression and metastases. When CEACAM1 is attached to NETs, it becomes a focal point of adhesion for cancer cells and, therefore, is suggested as a potential therapeutic target for preventing metastatic progression and immune evasion. In preclinical studies, CM24 has been shown to bind directly to NETs and to inhibit NET-induced cancer cell migration.

CM24, a first-in-class monoclonal antibody with the potential to treat multiple cancers, blocks CEACAM1, an immune checkpoint protein that supports tumor immune evasion and survival through multiple pathways. The Company is evaluating CM24 in patients with metastatic pancreatic cancer (PDAC) in combination with the PD-1 inhibitor nivolumab and chemotherapy in a randomized Phase 2 study. The primary endpoint of this Phase 2 study is to evaluate preliminary efficacy through overall survival in second-line PDAC.

"These encouraging biomarker results provide initial evidence of certain mechanistically relevant biomarkers and may enable us to implement a biomarker-driven strategy that could identify patients who will benefit from CM24," said Gil Efron, Chief Executive Officer, Purple Biotech. "We look forward to further data that may establish these findings in our ongoing randomized Phase 2 clinical study evaluating CM24 in combination with nivolumab and chemotherapy for treatment of PDAC."
