“We are excited to present new clinical and preclinical data at this year’s AACR Annual Meeting” said George Chen, Founder, Chairman and Chief Executive Officer of D3 Bio. “These presentations will showcase our comprehensive KRAS pipeline, including Elisrasib (D3S-001), our next-generation KRAS G12C inhibitor, D3S-002, a selective ERK1/2 inhibitor designed with a unique profile for combination strategies to enhance clinical efficacy and overcome resistance to KRAS G12C inhibitors; and D3S-003, our differentiated KRAS G12D inhibitor addressing large unmet medical needs in pancreatic and colo-rectal cancers. These data highlight D3 Bio’s strong scientific progress and commitment to advancing transformative therapies for patients with KRAS-driven cancers. We look forward to engaging with the global scientific community and sharing our progress at AACR and ultimately bringing new treatment options to patients.”
About Elisrasib (D3S-001)
Elisrasib is a nextgeneration KRAS G12C inhibitor designed for rapid, complete, and selective target engagement. It covalently binds the GDP-bound (OFF) form of KRAS G12C, effectively blocking nucleotide cycling and suppressing oncogenic signaling. Preclinical studies show robust potency, complete KRAS G12C engagement at clinically relevant exposures, and CNS penetration capability. Elisrasib‑ is currently being evaluated globally in a Phase 2 monotherapy and combination trial across KRAS G12C–mutant solid tumors including NSCLC, CRC, and others.
Key publications:
- Cancer Discovery (2024) 14(9):1675–1698
- Nature Medicine (2025) 31(8):2768–2777
About D3S‑002
D3S‑002 is a selective ERK1/2 inhibitor strategically designed for combination approaches, providing vertical MAPK‑pathway inhibition to enhance efficacy and overcome acquired resistance, particularly in tumors previously treated with KRAS G12C inhibitors.
Key publication:
- Cancer Res 1 April 2023; 83 (7_Supplement): 5501.
About D3S‑003
D3S‑003 is a differentiated KRAS G12D inhibitor targeting both OFF and ON conformations to address one of the most common KRAS mutations. The program aims to broaden D3 Bio’s multi‑allele KRAS franchise and deliver new solutions to the heterogeneous and evolving landscape of KRAS‑driven cancers.
