Diabetes is an increasing cause of atherosclerotic and cardiovascular illnesses in South Korea. The clinical application of ultrasound for measuring carotid intima-media thickness, which helps in early detection and surveillance of atherosclerosis, is advancing. Due to lifestyle changes and an aging population, Koreans, especially diabetics, are developing more vascular diseases and are at higher risk for peripheral vascular disorders. Diabetics with lower limb peripheral artery disease require effective therapy to avoid major complications and a reduced quality of life. Although licensed for symptom control, Clopidogrel and Cilostazol have not yet been established for primary prevention of cardiovascular risks. These medications will be evaluated for their potential as primary preventive agents against cardiovascular disease in type 2 diabetes patients. The goal of this research is to investigate the efficacy of Cilostazol and Clopidogrel in inhibiting the progression of carotid atherosclerosis and to evaluate their influence on hemorheological changes in individuals with Type 2 diabetes. The goal of this research is to investigate the efficacy of Cilostazol and Clopidogrel in inhibiting the progression of carotid atherosclerosis and evaluating their influence on alterations in blood flow among individuals with Type 2 diabetes.

Comparison of Clopidogrel-based Antiplatelet Therapy Versus Warfarin As Secondary Prevention Strategy for AntiPhospholipid Syndrome-related STROKE (APS-STROKE)

Antiphospholipid syndrome (APS) has a close association with ischemic stroke; however, the optimal treatment strategy for APS-related stroke has yet to be established. The clinical guidelines suggest using warfarin for APS-related stroke, but these suggestions are largely based on retrospective studies from the 1990s and expert opinion, rather than high-quality clinical trials. Moreover, the evidence on the role of antiplatelet drugs other than aspirin (e.g., clopidogrel) in APS-related stroke is particularly limited. Considering the relatively young age of patients with APS and the high clinical burden of using warfarin, it is necessary to verify whether warfarin is essential. Thus, the investigators aim to compare clopidogrel-based antiplatelet therapy and warfarin as a secondary preventive medication for patients with APS-related stroke. APS-STROKE is an exploratory, multicenter, prospective, randomized, open, blinded-endpoint clinical trial. Adult patients with definite APS who have a history of ischemic stroke will be included. Patients with high-risk APS (triple positivity or persistently high titers of anti-cardiolipin or anti-β2-glycoprotein I antibodies), systemic lupus erythematous, or indications for continued antiplatelet or anticoagulant therapy will be excluded. Eligible patients will be 1:1 randomized to receive clopidogrel-based antiplatelet therapy or warfarin. Patients assigned to the clopidogrel-based antiplatelet therapy group will be permitted to use additional antiplatelet drugs other than clopidogrel at the investigator's discretion. The primary outcome is a composite of any death, major adverse cardiovascular events, systemic thromboembolic events, and major bleeding during a follow-up period of at least 4 years. This study would provide valuable information for determining the optimal secondary prevention strategy for APS-related stroke.

Abstract 1430: In vivo PoC study and design for Phase I clinical study of SJP1604, a nucleolin-targeted therapeutic agent to treat entire population of relapsed/refractory acute myeloid leukemia patients

Author: Lee, Soo Jin ; Huh, Eun-Hye ; Ki, Min-Hyo ; Moon, Sung Hwan ; Park, Yongbin ; Um, Jihyun ; Kim, So Hee ; Lee, Dohyeong ; Lee, Je-Hwan

AbstractSJP1604 (APTA-16) is an aptamer-drug conjugate (APTA-DC) specifically targeting nucleolin, which is highly expressed only on the cell membrane of acute myeloid leukemia (AML) cells including relapsed/refractory aute myeloid leukemia (R/R AML). We previously presented the outstanding anti-leukemic activity of SJP1604 on AML cells including drug-resistant AML cells while standard chemotherapies showed no efficacy in vitro and in vivo. Therefore, we were able to conclude that only SJP1604 exhibits excellent resistance overcoming efficacy regardless of genetic defects of AML cells. Additionally, we recently identified that SJP1604 markedly eradicated AML cell engraftment with decreasing expression level of nucleolin protein in the bone marrow cells of MOLM-13 xenograft mouse model. These findings demonstrate that SJP1604 contributes to anti-leukemic effects through the regulation of nucleolin protein. We also figured out that nucleolin as a clinical biomarker was significantly highly expressed on AML and R/R AML patient-derived bone marrow cells. In particular, nucleolin expression is highly overexpressed in the bone marrow cells of entire population of R/R AML patients. Upto recent, considered as one of the major targeted therapeutics for AML, FLT3 inhibitors can target 25-30% of AML patients only. Therefore, our results mentioned above are very noteworthy finding showing the high potential of SJP1604 to be further developed as the first innovative targeted therapy to treat entire population of R/R AML patients. Herein, we show a phase I clinical trial design of SJP1604 to perform an open-label, first-in-human, dose escalation study to evaluate the safety, tolerability, pharmacokinetics and anti-tumor activity in patients with R/R AML.Citation Format: Jihyun Um, Dohyeong Lee, So Hee Kim, Eun-Hye Huh, Yongbin Park, Sung Hwan Moon, Soo Jin Lee, Je-Hwan Lee, Min-Hyo Ki.

Abstract 1454: Antitumor activity of a selective FAK/Pyk2 inhibitor, SJP1602 against TNBC as well as CRC

Author: Lee, Kug Hwa ; Cho, Hyoung Min ; Ki, Min-Hyo ; Hong, Sungpyo ; Ahn, Soon Kil ; Park, Yongbin

AbstractFocal adhesion kinase (FAK) is a cytoplasmic tyrosine kinase that serves as a key mediator in response to integrin and growth factor signaling to control multiple aspects of cellular behavior. High expression and/or aberrant activation of FAK is observed in a broad range of human cancers, contributing to malignant phenotype in cancer and development of tumor resistance. FAK, therefore, has been a prominent target in oncology and a small number of FAK inhibitors are currently in clinical development. However, selective FAK inhibitors have shown insufficient antitumor responses due to a potential compensatory role of proline-rich tyrosine kinase 2 (Pyk2), a homologue of FAK, and require dual specific FAK/Pyk2 inhibition. SJP1602 is a novel dual inhibitor of FAK and Pyk2 without multi-kinase inhibition. We have previously reported that SJP1602 is highly specific against FAK and Pyk2 and its antitumor efficacy in triple negative breast cancer (TNBC) is superior over the clinically active FAK inhibitors. In this study, we further assessed pharmacological efficacy of SJP1602 in another type of cancer, colorectal cancer (CRC). As evaluated by cell-based ELISA, SJP1602 has nanomolar potency against FAK and Pyk2 in a panel of CRC cell lines. Validation through immunoblotting analyses revealed significant reduction of FAK/Pyk2 activation by treatment of SJP1602 in CRC cell lines, consistent with previous observations in TNBC cell lines. We then investigated the inhibition efficiency of SJP1602 in three-dimensional (3D) spheroid models using the CRC cell lines. As determined by CellTiter-Glo 3D cell viability assay, SJP1602 showed the significantly lower IC50 values than other FAK inhibitors. Next, to investigate the mechanism of action (MOA) of SJP1602, we examined changes in activation of several FAK/Pyk2-mediated signaling pathways. As shown by immunoblotting analyses, SJP1602 decreased JAK2 and Akt activity and increased the expression levels of cleaved caspase 3, a critical marker of apoptosis. Further assessment of SJP1602 in vivo showed significant antitumor activities in different human CRC xenograft models containing BRAF-mutant or KRAS-mutant tumors. In addition, the specificity and MOA of SJP1602 were confirmed using xenograft tumors. In consistent with in vitro results, SJP1602 reduced JAK2 and Akt activity in tumors from mice with SJP1602 administration. Therefore, our results demonstrate that SJP1602 has the strong antitumor efficacy in vitro and in vivo via downregulation of JAK2 and PI3K/Akt signaling pathways. SJP1602 is currently undergoing preclinical toxicology studies and in vitro safety evaluation. Taken together, our data provides promising preclinical results for the further development of SJP1602 as a potent anti-cancer agent in TNBC, CRC and resistant cancer involving FAK activation.Citation Format: Kug Hwa Lee, Hyoung Min Cho, Yongbin Park, Sungpyo Hong, Soon Kil Ahn, Min-Hyo Ki.

Abstract 5152: SJP1604, a nucleolin-targeted therapeutic agent for relapsed/refractory acute myeloid leukemia

Author: Moon, Sung Hwan ; Lee, Soo Jin ; Um, Jihyun ; Lee, Dohyeong ; Ki, Min-Hyo ; Park, Yongbin

AbstractAcute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) are cancers characterized by the rapid growth of abnormal white blood cells. Although the standard first-line therapy leads to high rates of remission, approximately 30% of the treated patients are refractory and more than 50% of them face a relapse because of the occurrence of drug resistance and high toxicity. Therefore, there is a strong unmet medical need for the next-generation targeted therapy to overcome drug resistance and reduce toxicity in AML/MDS. Here, we designed an aptamer-drug conjugate (SJP1604) specific for nucleolin, which is highly expressed only on the cell membrane of cancer cells including AML cells. We identified that SJP1604 (APTA-16) inhibited the growth of AML cells and drug-resistant AML cells in vitro. SJP1604 presented outstanding anti-leukemic efficacy in vivo via syngeneic mouse model and xenograft mouse model. In addition, the synergistic effects were observed upon combination treatmeant with venetoclax in vitro. We also figured out that nucleolin as a clinical biomarker was significantly highly expressed on relapsed/refractory (R/R) AML patient-derived bone marrow cells ex vivo. SJP1604 selectively targeted cancer cells by nucleolin-binding on cell membrane with its high targeting ability and plasma stability owing to its unique conformational property, therefore, it demonstrated less cytotoxicity in vitro/in vivo and a superior therapeutic index based on AUC comparison in pharmacokinetic studies. The mechanism of the anti-leukemic efficacy of SJP1604 was also studied. First of all, SJP1604 decreased the expression of nucleolin and inactivated NFκB signaling pathway via dephosphorylation of NFκB, which resulted in diminished expression of DNMT1 followed by restored p15 expression. In addition, SJP1604 increased p53 expression and decreased bcl-2 expression in the protein and mRNA level. These could be one of potential mechanism of anti-leukemogenesis of SJP1604. In conclusion, these findings suggest that SJP1604 targeting nucleolin could be developed as a first-in-class drug for relapsed/refractory AML and MDS. GLP safety/toxicology studies of SJP1604 have been completed and clinical trials will be initiated in 2020.Citation Format: Jihyun Um, Dohyeong Lee, Yongbin Park, Sung Hwan Moon, Soo Jin Lee, Min-Hyo Ki.
