Below are the details for the poster:
Wednesday April 12, 2022, 9:00AM – 12:30PM
Session PO.MCB06.01 - Cell Cycle Control and Cell Cycle Regulators as Therapeutic Targets

TP-1287 is an investigational oral CDK9 inhibitor that has shown favorable oral bioavailability in preclinical models. TP-1287 is enzymatically cleaved, yielding the active moiety, a potent inhibitor of CDK9.1 Inhibiting CDK9 is thought to downregulate the transcription of target genes, including MCL-1, reducing leukemic blast viability in MCL-1–dependent hematologic malignancies, and c-MYC, an important oncogene across multiple tumor types.2, 3, 4 TP-1287 is in a Phase 1 first-in-human study of oral TP-1287 in patients with advanced solid tumors (NCT03604783).
Ombipepimut-S Emulsion (DSP-7888) is an investigational immunotherapeutic cancer vaccine containing 2 peptides that induce WT1-specific cytotoxic T lymphocytes (WT1-CTLs) and helper T cells to attack WT1-expressing cancerous cells found in various types of hematologic malignancies and solid tumors.5, 6 Researchers have identified that adding helper T-cell–inducing peptides improved WT1-specific CTL induction, which may contribute to tumor cytotoxicity.5 Ombipepimut-S Emulsion is in a Phase 1/2 study with immune checkpoint inhibitors in adult patients with advanced solid tumors (NCT03311334).
TP-0184 is an investigational inhibitor of activin receptor-like kinase 2 (ALK2) and ALK5 (also known as TGFβR1). This bimodal inhibitor is believed to downregulate multiple TGF-β superfamily signaling pathways, enabling hematopoietic regulation in myelodysplastic syndrome (MDS) through hepcidin decreases, bioavailable iron increases, and hemoglobin restoration, as well as antitumor activity in several cancers.7, 8, 9 TP-0184 is in two clinical trials; A Phase 1/2 study to treat anemia in adults with IPSS-R low or intermediate risk MDS (NCT04623996); A first-in-human study of oral TP-0184 in patients with advanced solid tumors (NCT03429218).
