Key Highlights
- CLK (CDC-like kinase) inhibitors target the CLK1, CLK2, CLK3, and CLK4 isoforms, which regulate pre-mRNA splicing via SR protein phosphorylation. They are mainly being developed for cancer treatment, especially in tumors with spliceosome mutations or splicing dependency.
- Among the four family members of CLKs, CLK1 has been structurally and functionally well characterized. CLK1, also termed STY, has been identified to be auto-phosphorylated at Ser/Thr/Tyr residues and phosphorylates Ser residues of its substrates.
- Recent studies have linked bispecific tyrosine phosphorylation-regulated kinases (DYRK1A, 1B, 2-4) and CDC2-like kinases (CLK1-4) to various neurological disorders in humans. Therefore, developing potent and selective inhibitors of these kinases and testing them as therapeutic agents is encouraging.
- Emerging biotech companies are actively advancing CLK inhibitor programs, reflecting growing momentum in RNA splicing-targeted oncology. Chordia Therapeutics’s Rogocekib (CTX-712), is a first-in-class pan-CLK inhibitor that has demonstrated encouraging anti-tumor activity in early clinical studies. BlossomHill Therapeutics’s BH-30236, is being evaluated for hematological malignancies such as Acute Myeloid Leukemia (AML) and myelodysplastic syndromes. In parallel, Biosplice Therapeutics is advancing Lorecivivint (SM04690) and Cirtuvivint (SM08502), Curis is developing Emavusertib (CA-4948).

Lorecivivint (SM04690): Biosplice Therapeutics
Lorecivivint is a small-molecule suspension intended to be injected 1-2 times per year into the knee joint. Lorecivivint, evaluated in 11 clinical trials, significantly improved pain and function in patients with a very good safety profile. Results from Biosplice’s Phase III OA-07 trial also showed that lorecivivint led to improvements in medial joint space width (JSW) on imaging over multiple years.In January 2026, Biosplice Therapeutics announced today that it has submitted its NDA to the FDA for approval of its novel therapy for the treatment of knee osteoarthritis.
Rogocekib (CTX-712): Chordia Therapeutics
Highly selective for CLK, CTX-712 is an orally available, first-in-class pan-CLK inhibitor. In several preclinical models, it have confirmed that it can induce cancer cell death in vitro, and induce anti-tumor effects in vivo. CTX-712 was confirmed proof of concept (POC) in a first in human phase I clinical trial conducted in Japan. It is currently being evaluated in early-phase clinical trials, including a Phase I/II study in patients with refractory or relapsed AML and myelodysplastic syndromes. Rogocekib for the treatment of r/r AML had been granted Orphan Drug Designation (ODD) by the US FDA.BH-30236: BlossomHill Therapeutics
BH-30236 is a novel, orally available, macrocyclic, ATP-competitive, highly potent and selective inhibitor of CDC-like kinase (CLK) designed to address dysregulated RNA splicing events that drive tumor growth and disease progression. In preclinical studies, BH-30236 demonstrated in vitro efficacy in patient-derived AML cells, including cells insensitive to venetoclax. BH-30236 is currently being evaluated as a monotherapy or in combination with venetoclax in a first-in-human, Phase I/Ib dose escalation study in adult participants with relapsed or refractory AML or higher-risk myelodysplastic syndrome (HR-MDS).Recent Developments in the CLK Inhibitors Market
