kt-3283 / Rakovina Therap - LARVOL DELTA

A bi-functional PARP-HDAC inhibitor with activity in Ewing sarcoma. (PubMed, Clin Cancer Res) - "Our data demonstrates the preclinical justification for studying the benefit of dual PARP and HDAC inhibition in the treatment of Ewing sarcoma in a clinical trial and provides proof-of-concept for a bi-functional single-molecule therapeutic strategy."

A bifunctional inhibitor of PARP and HDAC enzymes with activity in Ewing sarcoma 3D spheroid and metastasis models (AACR 2023) - "PARP inhibition combined with HDAC inhibition has demonstrated enhanced efficacy in pre-clinical studies in various tumor indications, and a clinical trial of olaparib and vorinostat combination therapy against metastatic breast cancer is currently ongoing. Kt-3283 shows potent inhibition of PARP1/2 and HDAC activities. It induces S and G2/M cell cycle arrest and DNA damage, and inhibits 3D spheroid growth and metastatic potential of ES cells. Further investigation of this bifunctional single-molecule inhibitor may offer a novel treatment opportunity for ES and other solid tumors with limited responses to PARPi."
