TYME-18 Demonstrates Anti-Cancer Effect in New Preclinical Data Presented at AACR 2020
Tyme Technologies, Inc. (NASDAQ: TYME), an emerging biotechnology company developing cancer metabolism-based therapies (CMBTstm), announced new preclinical findings that describe the unique anti-cancer effects of its cancer metabolism-based pipeline candidate, TYME-18, that are being presented at the American Association for Cancer Research 2020 Virtual Meeting from June 22 to June 24, 2020.
TYME's CMBTs are proprietary investigational compounds that leverage cancer's altered metabolism and associated vulnerabilities to specifically disrupt fundamental cellular processes. TYME-18 is focused on leveraging decreasing pH levels and toxic tumor environment, while compromising lipid barriers and membrane proteins.
"We believe the opportunity for a safe and effective intra-tumoral agent like TYME-18 could be substantial for both cancer patients with tumors that are difficult or impossible to surgically resect, as well as situations where radiotherapy is considered high-risk," said Dr. Giuseppe Del Priore, MD, Chief Medical Officer at TYME. "TYME-18's preclinical development is ongoing with the goal of identifying an IND pathway during 2020."
TYME-18 has been evaluated in three preclinical mouse xenograph studies, each with encouraging efficacy. To investigate the effects of the individual components of TYME-18 on tumor growth, an in vivo xenograft experiment was conducted using the mouse colon cell line CT26 (Figure 1). A minor reduction in tumor cell mass was observed in response to TYME-18's surfactant component alone, with a statistically significant response observed in the group treated with TYME-18 (surfactant component + sulfonic acid component)1,2 (p=0.001) (Figure 1). The preclinical data showed that 91.6% (11/12) of mice treated with TYME-18 were tumor-free by study end compared with tumor growth of approximately 16 times mean growth in the control group. None of the mice in the control or surfactant alone group achieved tumor-free status, although 25% (3/12) of the surfactant alone group had tumor shrinkage from baseline. Results from this study replicate and confirm observations in preliminary TYME-18 studies.
While not a primary focus of the preclinical studies, TYME-18 did not show local or systemic toxicities in treated mice.
Results of this preclinical study were presented at the American Association for Cancer Research Virtual Meeting from June 22 to June 24, 2020. The poster is available on our website (www.tymeinc.com/data-publications).

About TYME-18
TYME-18 is composed of a proprietary surfactant delivery agent with a specific sulfonic acid component2. It is designed for intra-tumoral administration of difficult to treat tumors and leverages the acidic tumor microenvironment and signaling pathways to kill cancer cells. TYME-18 is distinct in composition, but like SM-88, aims to leverage susceptibilities of a cancer that are related to its altered metabolism. Initial preclinical data for TYME-18 in animal tumor models demonstrate rapid and complete tumor regression, with no reported local or systemic toxicities. TYME-18 continues to be studied as a potential therapy for difficult to treat tumors that may not be eligible for surgical or other interventions.
About SM-88
SM-88 is an oral investigational modified proprietary tyrosine derivative that is believed to interrupt the metabolic processes of cancer cells by breaking down the cells' key defenses and leading to cell death through oxidative stress and exposure to the body's natural immune system. Clinical trial data have shown that SM-88 has demonstrated encouraging tumor responses across 15 different cancers, including pancreatic, lung, breast, prostate and sarcoma cancers with minimal serious grade 3 or higher adverse events.
About Tyme Technologies
Tyme Technologies, Inc., is an emerging biotechnology company developing cancer therapeutics that are intended to be broadly effective across tumor types and have low toxicity profiles. Unlike targeted therapies that attempt to regulate specific mutations within cancer, the Company's therapeutic approach is designed to take advantage of a cancer cell's innate metabolic weaknesses to compromise its defenses, leading to cancer cell death through oxidative stress and exposure to the body's natural immune system.
