| Agency | U.S. FDA |
| Designation | Breakthrough Therapy |
| Product | Olomorasib (monotherapy) |
| Indication | Advanced pancreatic cancer with KRAS G12C mutation |
| Patient Population | ≥1 prior systemic therapy |
| Biomarker Requirement | KRAS G12C mutation (FDA-approved test) |
| Previous Designation | NSCLC combination with KEYTRUDA® (first-line, PD-L1 ≥50%) |
Drug Profile & Scientific Innovation
- Molecule Type: Investigational, potent, and highly selective next-generation KRAS G12C inhibitor
- Target Specificity: Specifically designed to target KRAS G12C mutation
- Pharmacokinetic Advantages:
- High predicted target occupancy
- Potent inhibition in both monotherapy and combination regimens
- Therapeutic Innovation: Addresses historically “undruggable” KRAS target with precision approach
Strategic Regulatory Portfolio
Dual Breakthrough Therapy Designations
- Pancreatic Cancer (New): Monotherapy for advanced disease post-first-line
- Unmet Need: Limited treatment options for KRAS G12C-mutated pancreatic cancer
- Patient Population: Heavily pre-treated with poor prognosis
- Non-Small Cell Lung Cancer (Previously Granted): Combination with KEYTRUDA®
- Indication: First-line locally advanced/metastatic NSCLC
- Biomarker Requirements: KRAS G12C mutation + PD-L1 expression ≥50%
- Therapeutic Approach: Immunotherapy combination strategy
Market Opportunity & Competitive Landscape
Pancreatic Cancer Context
- KRAS G12C Prevalence: Present in approximately 1–2% of pancreatic cancer cases
- Treatment Gap: No approved targeted therapies specifically for KRAS G12C-mutated pancreatic cancer
- Prognosis Challenge: Advanced pancreatic cancer has 5-year survival rate of <3%
- Competitive Moat: First-mover advantage in this specific molecular subset
KRAS Inhibitor Market
- Pioneering Class: KRAS G12C inhibitors represent breakthrough in targeting previously undruggable oncogene
- Competitive Differentiation: Olomorasib’s pharmacokinetic properties may offer dosing and efficacy advantages
- Combination Potential: Dual designation strategy demonstrates versatility across therapeutic approaches
Strategic Implications for Eli Lilly
