Metastatic Colorectal Cancer (mCRC)
Onvansertib in combination with second-line standard of care (SoC) is reducing tumor growth and increasing progression-free survival.
KRAS Mutations in mCRC*
* Jones R et al. Br J Cancer. 2017 Mar 28;116(7):923-929
Gaps in KRAS-mutated mCRC therapies present a significant unmet need
- 40%+ of mCRC patients have a KRAS mutation and therefore do not benefit from targeted therapies (e.g., EGFR inhibitors) in first-line therapy
- Current investigational therapies for KRAS-mutated mCRC from Amgen, Mirati only address the G12C mutation, not the most prevalent KRAS mutations
- Onvansertib has the potential to address all KRAS mutations because PLK1 activation is downstream of RAS
The prognosis for second-line mCRC patients is poor
- For second-line mCRC patients, the 5-year survival rate is 10%
- Historical controls showed a 5-13% objective response rate to second-line standard of care FOLFIRI+bevacizumab and a median progression-free survival of 4.5 – 5.7 months
