YELIVA is a Phase II-stage, proprietary, first-in-class, orally-administered sphingosine kinase-2 (SK2) selective inhibitor with anticancer and anti-inflammatory activities, targeting multiple oncology, inflammatory and gastrointestinal indications. By inhibiting the SK2 enzyme, YELIVA blocks the synthesis of sphingosine 1-phosphate (S1P), a lipid signaling molecule that promotes cancer growth and pathological inflammation.
Mark L. Levitt, MD, PhD, RedHill’s Medical Director, Oncology, said: "Cholangiocarcinoma is a cancer with a poor prognosis. Patients suffering from this disease have very few treatment options, and they are of limited efficacy. Based on promising preclinical data, as well as results from three previously treated cholangiocarcinoma patients who took part in the Phase I study with YELIVA, we are hopeful that YELIVA could potentially provide a much-needed new treatment option for patients. We are very pleased with the Orphan Drug designation and are advancing our preparations for a Phase IIa study to evaluate the safety and efficacy of YELIVA in patient suffering from unresectable, intrahepatic and extrahepatic cholangiocarcinoma, which we plan to initiate in the third quarter of this year."
Cholangiocarcinoma (bile duct cancer) is a highly lethal malignancy for which there is a strong need for more effective systemic treatments. Approximately 8,000 people are diagnosed with intrahepatic and extrahepatic bile duct cancers annually in the U.S.1, with recent studies showing an increased incidence of cholangiocarcinoma, mainly attributed to recent advancements in diagnosis of this disease2. Surgery with complete resection remains the only curative therapy for cholangiocarcinoma, however only a minority of patients are classified as having a resectable tumor at the time of diagnosis3. Additional treatment options include radiation therapy and chemotherapy; however, the efficacy of these treatments in cholangiocarcinoma patients is also limited. Despite overall advances in the ability to diagnose and treat patients with cholangiocarcinoma, the prognosis for these relapse patients who have failed initial chemotherapy remains very poor, with an overall median survival of approximately one year4. The 5-year relative survival rates of intrahepatic and extrahepatic cholangiocarcinoma patients range between 2% to 30%, depending on the tumor type and stage at diagnosis5.
Final results from the Phase I study with YELIVA in patients with advanced solid tumors confirmed that the study, conducted at the Medical University of South Carolina (MUSC) Hollings Cancer Center, successfully met its primary and secondary endpoints, demonstrating that the drug is well-tolerated and can be safely administered to cancer patients at doses that provide circulating drug levels that are predicted to have therapeutic activity.
Of the three patients with cholangiocarcinoma treated in the Phase I study, all of whom had prior therapy, one subject achieved a sustained partial response (Overall Survival (OS) = 20.3 months) and the other two subjects had prolonged stable disease (OS = 17.6 and 16.3 months).
RedHill plans to initiate a Phase IIa clinical study with YELIVA in patients with advanced, unresectable, intrahepatic and extrahepatic cholangiocarcinoma in the third quarter of 2017. The single-arm study will evaluate YELIVA as a single agent in cholangiocarcinoma patients with a primary endpoint of determining the response rate of cholangiocarcinoma to this treatment.
A Phase II study with YELIVA for the treatment of advanced hepatocellular carcinoma (HCC) is ongoing at MUSC Hollings Cancer Center. The study is supported by a $1.8 million grant from the NCI, awarded to MUSC, which is intended to fund a broad range of studies on the feasibility of targeting sphingolipid metabolism for the treatment of a variety of solid tumor cancers, with additional support from RedHill.
A Phase Ib/II study with YELIVA for the treatment of refractory or relapsed multiple myeloma is ongoing at Duke University Medical Center. The study is supported by a $2 million grant from the NCI Small Business Innovation Research Program (SBIR) awarded to Apogee Biotechnology Corp. (Apogee), in conjunction with Duke University, with additional support from RedHill.
A Phase I/II clinical study evaluating YELIVA in patients with refractory/relapsed diffuse large B-cell lymphoma as well as Kaposi sarcoma patients is ongoing at the Louisiana State University Health Sciences Center. The study is supported by a grant from the NCI awarded to Apogee, with additional support from RedHill.
A Phase Ib study to evaluate YELIVA as a radioprotectant for prevention of mucositis in head and neck cancer patients undergoing therapeutic radiotherapy is planned to be initiated in the third quarter of 2017.
A Phase II study to evaluate the efficacy of YELIVA in patients with moderate to severe ulcerative colitis is planned to be initiated in the second half of 2017.
About YELIVA (ABC294640):
YELIVA (ABC294640) is a Phase II-stage, proprietary, first-in-class, orally-administered, sphingosine kinase-2 (SK2) selective inhibitor with anti-cancer and anti-inflammatory activities. RedHill is pursuing with YELIVA multiple clinical programs in oncology, inflammatory and gastrointestinal indications. By inhibiting SK2, YELIVA blocks the synthesis of sphingosine 1-phosphate (S1P), a lipid signaling molecule that promotes cancer growth and pathological inflammation. SK2 is an innovative molecular target for anticancer therapy because of its critical role in catalyzing the formation of S1P, which is known to regulate cell proliferation and activation of inflammatory pathways. YELIVA was originally developed by U.S.-based Apogee Biotechnology Corp. and completed multiple successful pre-clinical studies in oncology, inflammation, GI and radioprotection models, as well as the ABC-101 Phase I clinical study in cancer patients with advanced solid tumors. The Phase I study included the first-ever longitudinal analysis of plasma S1P levels as a potential pharmacodynamic (PD) biomarker for activity of a sphingolipid-targeted drug. The administration of YELIVA resulted in a rapid and pronounced decrease in S1P levels, with several patients having prolonged stabilization of disease. YELIVA received Orphan Drug designation from the U.S. FDA for the treatment of cholangiocarcinoma. The development of YELIVA was funded to date primarily by grants and contracts from U.S. federal and state government agencies awarded to Apogee Biotechnology Corp., including the U.S. National Cancer Institute, the U.S. Department of Health and Human Services’ Biomedical Advanced Research and Development Authority (BARDA), the U.S. Department of Defense and the FDA Office of Orphan Products Development.

About the Fractalkine project
Fractalkine is an immune regulatory factor, a so-called chemokine, that sends signals via the CX3CR1 receptor, also called G-protein coupled receptor 13 (GPCR13). The level of fractalkine and its receptor, CX3CR1 has been shown to be elevated in many inflammatory diseases, cancer and in chronic pain conditions. Kancera’s drug candidate KAND567 is the furthest developed drug candidate against CX3CR1 and has been shown to be effective against inflammation and pain in several preclinical disease models. Kancera is now preparing the project for clinical studies.
In the healthy individual, Fractalkine and its receptor, CX3CR1, regulate migration of immune cells from the blood capillary wall into areas where the immune system is needed. Animal studies show that Fractalkine’s receptor is not essential for survival and that important immune functions remain intact despite the lack of receptor.The body of research supports the overall hypothesis that CX3CR1 is more crucial to developing disease than to keeping the individual healthy. The basis for successful development of KAND567 lies in effectively addressing local inflammation while maintaining a healthy immune system.
In clinical trials, blocking of the Fractalkine system has been shown to have the desired effect against auto-immune diseases such as Crohn’s disease and rheumatoid arthritis in refractory patients. These positive studies have been conducted by the pharmaceutical company Eisai using a monoclonal antibody. The results of these studies means that the probability increases for the Kancera AB drug candidate KAND567 to achieve clinical and commercial success as the first small-molecule drug that works through the Fractalkine system to combat many common diseases.

Intrexon and ZIOPHARM Oncology, in an exclusive partnership with Merck KGaA, Darmstadt, Germany, are advancing a unique approach to develop therapeutic candidates for two CAR-T targets expressed on a wide range of tumor types, including hematologic malignancies and solid tumors.
The distinctive methodology centers on two technologies: the proprietary RheoSwitch Therapeutic System (RTS) platform to regulate expression of membrane-bound interleukin-15 (mbIL15) co-expressed with CARs and Sleeping Beauty non-viral gene integration.
"Sleeping Beauty and the RTS approach are a powerful combination to improve the manufacturing process and instill control over CAR-modified T cells co-expressing cytokines such as membrane-bound IL-15. The collaboration with Intrexon and Merck KGaA, Darmstadt, Germany, has been a catalyst to progress these next-generation gene therapy technologies. We are excited by the progress and look forward to advancing this innovative approach toward the clinic in mid-2018," said Laurence Cooper, M.D., Ph.D., Chief Executive Officer of ZIOPHARM.
The interleukin-15 (IL-15) cytokine is increasingly recognized as a key driver of therapeutic effect in CAR-T therapy, including in a recent Journal of Clinical Oncology publication which correlated lymphoma remissions with elevated IL-15 levels. Through the RTS gene switch, the expression of mbIL15 can be regulated to help CARs target cancers in a controlled manner, thus providing a new paradigm in T-cell therapy.
Additionally, the non-viral Sleeping Beauty transposon-transposase is an exceptional system for introducing genes encoding CARs and TCRs into T cells that holds multiple advantages over viral-based delivery systems. It simplifies genetic modification, and when coupled with reduced ex vivo processing, offers a pathway to shortened manufacturing and personalized T-cell therapies.

SRX3177 is developed on the rationale that concurrent PI3K inhibition can prevent resistance to CDK4/6 inhibition, and combined CDK4/6 and PI3K inhibition leads to synthetic lethality reported in a number of cancer types, including breast cancer and mantle cell lymphoma, and blocking the chromatin reader protein BRD4 downregulates MYC and cyclin D1 transcription, further promoting cell cycle arrest in G1.
The presentation will describe the discovery and early development of the molecularly designed small-molecule triple inhibitor SRX3177. Key highlights to be presented include:
SRX3177’s potent in vitro enzymatic inhibition profile (IC50: CDK4 = 2.54 nM, CDK6 = 3.26 nM; PI3Kα = 79.3 nM, PI3Kδ = 83.4 nM; BRD4-BD1 = 32.9 nM, BRD4-BD2 = 88.8 nM).
SRX3177 rational design based on thieno-pyranone scaffold and target modeling.
Up to 82-fold more potent than palbociclib in a panel of mantle cell lymphoma, neuroblastoma, and hepatocellular carcinoma cell lines.
5-Fold more potent in cancer cells than combination of BKM120 (PI3K inhibitor) + palbociclib (CDK4/6 inhibitor) + JQ1 (BRD4 inhibitor).
40-Fold less toxic to normal epithelial cells than combination of BKM120 + palbociclib + JQ1.
Cell cycle arrest and apoptosis induction with proven mode of action (p-AKT, p-Rb, chromatin release).
SignalRx is also announcing that it is seeking partnering opportunities to accelerate the development of this program and its PI3K-BRD4 program to advance novel small molecules into first-in-man clinical trials based on the promising profile of its inhibitors shown so far. Since these are single molecules with a single PK/PD and toxicity profile, there is a great opportunity to develop them as single therapeutics and streamline their development in combination therapies focused on companion diagnostics built around synthetic lethality discoveries in human cancers.
