TYK2ARTS-011
Autoimmune
ARTS-011 is a highly selective, potent and orally available TYK2 inhibitor with suitable pharmaceutical properties to be a potential therapy for inflammatory disorders. It exhibits excellent selectivity against other JAK family kinases and demonstrates great DMPK properties and safety profiles. ARTS-011 has completed Phase 1 clinical trial in healthy volunteers in China.
CDK2ARTS-021
Oncology
ARTS-021 is a highly potent and selective inhibitor of CDK2, a key enzyme involved in cell cycle regulation. In preclinical studies, ARTS-021 demonstrated ability to selectively inhibit the growth of tumors with CCNE1 amplification. It can also overcome the resistance that ER+/HER2- breast cancer cells develop against CDK4/6 inhibitors. Partnering with Avenzo Therapeutics, ARTS-021 (AVZO-021) is being studied in a Phase 1 study in the U.S. for the treatment of advanced solid tumors and will be advanced globally.
Synthetic lethal target
Oncology
Isoform-selective kinase inhibitor
Oncology
ARTS-023 is an orally bioavailable CDK4 inhibitor with high selectivity over CDK6. In enzymatic assays, ARTS-023 potently inhibits the CDK4/Cyclin D1 complex, with an IC₅₀ in the sub-nanomolar range, demonstrating strong selectivity against CDK6 and other CDKs tested. At
low nanomolar concentrations, ARTS-023 effectively inhibits Rb phosphorylation and blocks the G1/S cell cycle transition, leading to growth arrest in ER-positive breast cancer cell lines. ARTS-023 has also shown robust anti-tumor activity as a single agent in multiple ER-positive breast cancer xenograft models. With the potential to become a best-in-class oncology therapy for patients with HR+/HER2- breast cancer, ARTS-023 (AVZO-023), in partnership with Avenzo Therapeutics, is currently being evaluated in a Phase 1 study in the U.S. for the treatment of advanced solid tumors, with plans for global development.
