Under this year's virtual meeting format, Dr. Kourelis will present a pre-recorded, narrated slide presentation on the multi-center dose escalation study of PT-112 in multiple myeloma patients who are relapsed or refractory to available therapy (NCT03288480). The study was designed and launched following non-clinical work conducted in the Cancer Genetics Laboratory of P. Leif Bergsagel, M.D. at the Mayo Clinic in Scottsdale, Arizona.

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. Further, PT-112 harbors a property known as osteotropism, or the propensity of the drug to reach its highest concentrations in certain areas of the bone, making it a candidate for treatment of patients with cancers that originate in, or metastasize to, the bone. 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 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. The Phase I study in patients with relapsed or refractory multiple myeloma to be presented at ASH is the third completed Phase I study of PT-112.

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).
