KANAGAWA, Japan, June 7, 2022 /PRNewswire/ -- Chordia Therapeutics Inc. ("Chordia"), a biotech company engaged in the research and development of novel therapies for cancers, today announced that it has presented the interim results from the Phase 1 clinical trial of CTX-712, a selective pan-CDC-like kinase ("CLK") inhibitor discovered by Chordia, at the 2022 Annual Meeting of the American Society of Clinical Oncology (ASCO), which was held from June 3 to June 7. A Phase 1 clinical trial of CTX-712 in solid tumors and hematological malignancies demonstrated a clinically acceptable safety profile. As for antitumor efficacy, it was observed in multiple subjects, establishing an initial Proof of Concept (POC). Dose limiting toxicities (DLTs) observed included dehydration, decreased platelet count, and hypokalemia, and the maximum tolerated dose (MTD) for twice-weekly dosing was determined to be 140 mg. Additionally, two partial responses (PRs) and two complete responses (CRs) were observed in patients with ovarian cancer and acute myeloid leukemia, respectively. A dose-dependent increase in systemic exposure was observed in pharmacokinetics (PK) analysis, and a dose-dependent increase in exon skipping of RNAs set as pharmacodynamics (PD) markers confirmed mRNA splicing modification by CTX-712. Further studies are currently underway to determine the recommended Phase 2 dosing. "It is a great honor to be involved in the first-in-human clinical trial of a new anticancer drug candidate with a novel mechanism of action," said Dr. Noboru Yamamoto, Director of the Department of Experimental Therapeutics at the National Cancer Center Hospital and Principal Investigator of the study. "Although it is still in the early stages of clinical trials, we hope that CTX-712 will become an effective treatment for patients with advanced, relapsed, or refractory malignancies in the future." ASCO abstract number: 3080 Title: A First-in-Human Phase 1 Study of CTX-712 in Patients with Advanced, Relapsed or Refractory Malignant Tumors About CTX-712 CTX-712 is a first-in-class, orally available and selective small molecule inhibitor of CDC-like kinase (CLK), a key regulator of the RNA splicing process that plays an important role in cell growth. CTX-712 inhibits the growth of various human tumor cell lines in vitro, and in addition, exhibits antitumor activity in multiple xenograft mouse models in vivo. Details of Phase 1 Clinical Trial The Phase 1 clinical trial in Japan is investigating the tolerability, safety, and pharmacokinetics (PK) of CTX-712 in patients with advanced, relapsed, or refractory malignancies. For details of the study, please refer to JapicCTI-184188. About RNA Splicing The RNA immediately after transcription is called precursor messenger RNA which contains noncoding sequences (introns) as well as coding sequences (exons) that are needed to make proteins. RNA splicing is a process to remove the introns and connect the exons to form mature mRNA, which is then translated into protein. About CDC-like Kinases (CLKs) Kinase is a general term for enzymes that catalyze the transfer of phosphate groups in biological substances, such as ATP, over to target substances that are called substrates. Over 500 protein kinases are known in humans, of which the CLK family consists of four members – CLK1, CLK2, CLK3, and CLK4, and phosphorylates serine/arginine-rich (SR) proteins as substrates. About Serine/Arginine-rich Proteins (SR Proteins) SR protein is a general term for a group of proteins with serine (S) and arginine (R)-rich SR domains, of which about 10 types have been reported in humans. The serine in the SR domain is phosphorylated by CLK kinase. The phosphorylated SR proteins bind to the exon region of the precursor mRNA and facilitate the incorporation of the bound exon into the mature mRNA during splicing. About Exon Skipping When CTX-712 inhibits CLK kinases and the SR protein dephosphorylates, a splicing change called exon skipping occurs, in which the exons fail to be incorporated into the mature mRNA.
