Building upon prior publication of the ICD effects of PT-112, the body of work to be presented is part of an effort to understand the metabolic pathways and cellular targets affected by PT-112 upstream of ICD initiation. "The data to be reported at the 32(nd) EORTC-NCI-AACR Virtual Symposium advance the body of knowledge around PT-112's pleiotropic mechanism of action and provide valuable information on further potential clinical applications of PT-112. As we continue our clinical study of this unique compound in patients with challenging cancers, such insights are important," said Robert Fallon, co-founder and chief executive officer, Phosplatin Therapeutics. "We are pleased to co-present this body of work under our fruitful collaboration with the Anel lab at the University of Zaragoza, Spain."

About PT-112

PT-112 is a novel small molecule conjugate of pyrophosphate that possesses a unique pleiotropic mechanism of action that promotes immunogenic cell death (ICD), through the release of damage associated molecular patterns (DAMPs) that bind to dendritic cells and lead to downstream immune effector cell recruitment in the tumor microenvironment. PT-112 represents the best-in-class small molecule inducer of this immunological form of cancer cell death and is currently under Phase II development. The first in-human study of PT-112 demonstrated an attractive safety profile and evidence of long-lasting responses among heavily pre-treated patients and won "Best Poster" within the Developmental Therapeutics category at the ESMO 2018 Annual Congress. The novelty of PT-112's pyrophosphate moiety also results in osteotropism, or the propensity of the drug to reach the mineralized bone. This property is of interest in cancer types that originate in or metastasize to the bone. The combination Phase Ib study of PT-112 with PD-L1 checkpoint inhibitor avelumab in solid tumors was reported in an oral presentation at the ESMO 2020 Virtual Congress.

About Phosplatin Therapeutics

Phosplatin Therapeutics is a privately held, clinical stage pharmaceutical company that holds exclusive global license to phosphaplatins, a family of small molecules rationally designed to circumvent the mechanisms of drug resistance and toxicity commonly associated with chemotherapeutic regimens. The company's lead candidate, PT-112, is a novel chemical entity under clinical development that exhibits a unique combination of properties, including immunogenic cell death and osteotropism. Clinical data generated to date across three Phase I studies have demonstrated single-agent anti-cancer activity and an attractive tolerability profile, and two Phase II studies of PT-112 are underway. The company's research and development work to date has spanned fifteen countries and been funded by private investors and family investment offices in the United States, Europe and Asia, along with a sub-license agreement for the development, commercialization and use of PT-112 in Greater China. The company sponsors the ongoing clinical study of PT-112 in combination with the PD-L1 inhibitor avelumab under a collaboration agreement with Pfizer and Merck KGaA, Darmstadt, Germany (operating as EMD Serono in the US and Canada).
