- SM-88 is an oral, investigational cancer metabolism-based therapy that has demonstrated confirmed clinical responses in 15 different cancers across four separate studies
- SM-88 is a new approach aimed at disrupting cancer metabolism in metastatic pancreatic cancer: ~ 50,000 cases annually in U.S. alone
- Targeted mechanism of action resulted in fewer than 2% of patients experiencing serious adverse events related to SM-88 in clinical trials
NEW YORK, NY, USA I September 30, 2019 I Tyme Technologies, Inc. (NASDAQ: TYME), an emerging biotechnology company developing cancer metabolism based therapies (CMBTs™), announced that its open-label Phase II TYME-88-Panc study evaluating SM-88 (racemetyrosine) as an oral monotherapy in patients with advanced pancreatic cancer continues to demonstrate encouraging overall (OS) results and has a well-tolerated safety profile. TYME also announced encouraging Quality of Life data for this challenging patient population. The supporting data from the study were presented at the European Society of Medical Oncology Congress (ESMO) being held on September 27- October 1, 2019 in Barcelona, Spain. As a result of these clinical outcomes, TYME recently launched the multi-center randomized controlled pivotal stage of the TYME-88-Panc trial for use of SM-88 in patients with third-line pancreatic cancer.
TYME’s lead CMBT candidate, SM-88, was designed to leverage innate changes in cancer metabolism that are fundamental to support the cancer’s proliferation. The Warburg Effect, a process that helps most cancer cells adapt to changing conditions, is prevalent across most solid and hematological malignancies impacting energy production and the uptake of non-essential amino acids for cancer growth. SM-88 is a modified dysfunctional form of the amino acid tyrosine. Tyrosine is required for cancer cell growth and as a result, SM-88 is selectively consumed by the cancer cell, causing a disruption of protein synthesis that leads to catastrophic failure and cancer cell death.
“Given that there are no effective options to treat this poor prognostic patient population, we recently launched our SM-88 pivotal trial for patients with third-line pancreatic cancer. We are increasingly encouraged that SM-88 has the efficacy, safety and quality of life potential to be a new treatment approach for late-stage pancreatic patients,” said Giuseppe Del Priore, M.D., M.P.H., Chief Medical Officer at TYME. “Assessing the potential of emerging biomarkers, such as the evaluation of circulating tumor cells for predicting the outcome and the response to specific investigational medicines, such as SM-88, is an important next step to improve the prognosis of patients with metastatic cancers.”
The results from the multicenter open-label Phase II TYME-88-Panc study involved 49 heavily pretreated patients with radiographically progressive metastatic pancreatic cancer who had significant disease related morbidity before receiving TYME’s investigational agent SM-88. More than 80% of patients had received at least two prior lines of therapy. Of the 49 patients, 38 patients were evaluable for efficacy as defined in the protocol. This study is being performed under a TYME IND with input from the FDA prior to study initiation.
In this study, based on information available as of April 25, 2019, the median overall survival of the 38 evaluable patients was 6.4 months. Certain efficacy indicators correlated with greater OS, including achieving stable disease (SD) or better and decreases in circulating tumor cells (CTCs). Notably, patients achieving stable disease or better demonstrated a statistically significant (p=0.02) improvement in survival with a 92% reduction in risk of death (hazard ratio=0.08).The clinical benefit response (CBR) was durable with the majority of these patients remaining in stable disease or better at more than 7 months after receiving treatment with SM-88.
In the TYME-88-Panc study, baseline CTCs were an average of 142 cells/4ml. Of the 24 evaluable patients treated with SM-88 who had CTC readings available, 66.7% of those patients (16/24) showed a median decrease of 63% in CTC levels falling from baseline CTCs to a median of 21 cells/4ml. 42% of those patients (10/24) with available results reaching an 80% reduction or greater in CTCs demonstrated a 60% decrease in risk of death (hazard ratio=0.40).
A novel radiomics analysis was also conducted. The radiomic analysis of tumor texture correlated with CTCs at baseline (p=0.007). In addition, tumor texture was closely associated with the percentage change in CTCs on treatment (p=0.019) and OS (logrank p=0.001)
Quality of life (QOL) assessments were conducted as part of the TYME-88-Panc study. Generally, patients maintained their QOL throughout their treatment with SM-88. Patients reported low levels of GI-related symptoms (decreased appetite, nausea, vomiting, diarrhea), which are commonly reported in patients undergoing other treatments for pancreatic cancer. Score for pain and fatigue related questions showed that patients reported generally low levels of these symptoms also. Overall stability of weight was also reported. This is a key finding as patients with pancreatic cancer typically experience noticeable, but unintentional weight loss, which is a clinically meaningful indicator of poor prognosis.
As of April 25, 2019, the study reported that SM-88 was well tolerated with only 4.0% of patients (2 of 49) who experienced serious adverse events (SAEs) deemed at least possibly related to SM-88 (abdominal pain, arthralgia, and hypotension). One patient with reported SAEs continued on treatment.
The TYME-88-Panc research results are from an investigational study. SM-88 is not approved for the treatment of patients with any disease condition. Patients and physicians can access www.TYMETRIALS.com for more information about ongoing SM-88 clinical trials.
Details of this study were presented at the ESMO Congress in Barcelona, Spain on Sunday, September 29, 2019, from 12:00 PM CET to 1:00 PM CET during the Poster Display Session 2 in Poster Hall 4. The poster is available on our website (www.tymeinc.com/data-publications).

About Advanced Pancreatic Cancer
Advanced pancreatic cancer is a difficult-to-treat cancer with the lowest survival rates among all cancer types. Across all patients with pancreatic cancer, relative 5-year survival is 8% and is less than 3% for those with advanced disease.2 The median survival for patients in end-stage of the disease is approximately 3 months. There are two main types of pancreatic cancer - adenocarcinomas, which accounts for approximately 90% of all pancreatic cancer, and neuroendocrine tumors. Pancreatic cancer is relatively uncommon with new cases accounting for only 2.1% of all newly diagnosed cancers. However, pancreatic cancer is the fourth most common cause of cancer death for men and women in the United States.
SM-88 is an oral investigational modified proprietary tyrosine derivative that is hypothesized 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.
