Developing Biology-Driven Medicines and Expanding the Impact of Targeted Oncology

We develop differentiated therapies for patients in need that target nodes of cancer growth, spread, and therapeutic resistance in the Hippo and RAS onco- signaling networks

Hippo Pathway

RAS Pathway

  • Multiple ongoing clinical trials with expected data readouts in the next 12 months
  • Leaders in Hippo pathway with clinical stage TEAD1 inhibitor IK-930
    • Initial monotherapy dose escalation data in all comers, mesothelioma, and EHE in 4Q 2023
    • Broad combination potential including in EGFRm and RASm cancers, starting with osimertinib in NSCLC
  • Novel MEK/RAF inhibitor IK-595in IND-enablingstudies
    • IND in 2H 2023 with broad potential across RAF and RAS mutant cancers
  • BMS partnered program IK-175with clinical activity in bladder cancer
    • Potential for $50M in opt-infees by early 2024, $450M in milestones plus global royalties
  • Cash runway into 2026 with ~$80M added to balance sheet in 2023
