About H3B-8800

Splicing modulation is one of several research focus areas of H3 Biomedicine. A Phase 1 trial is underway in patients with hematologic malignancies for H3B-8800, the company’s first spliceosome pathway-targeting cancer therapeutic. H3B-8800 is a potent, selective and orally bioavailable small molecule modulator of wild-type and mutant SF3b complex, a splicing factor gene. The study is evaluating the safety and preliminary efficacy of H3B-8800 in patients with myelodysplastic syndromes (MDS), acute myeloid leukemia (AML), and chronic myelomonocytic leukemia (CMML) who carry mutations in splicing factor genes. In February 2018, H3 published preclinical data in Nature Medicine demonstrating that H3B-8800 modulates RNA splicing and shows preferential antitumor activity in a range of spliceosome-mutant cancer models.
