Tumor inflammation predicts better response to nivolumab alone in MSI-H CRC, while high mutational burden predicts benefit from nivolumab + ipilimumab. Our Nat Comm paper dives into CM142 and PD1 ± CTLA4 predictors with lead of @michael_overman. https://rdcu.be/eJHmS

Phase II @MDAndersonNews INTERCEPT-TT: TAS-102 cleared ctDNA in 5/15 (33%) CRC pts with MRD at 6mo, vs 2/30 (7%) in controls, and prolonged median DFS to 9.4mo vs 5.8mo. https://pubmed.ncbi.nlm.nih.gov/40669021/
Phase II Trial of TAS-102 in Colorectal Cancer Patients With Circulating Tumor DNA-Defined Minimal Residual Disease After Adjuvant Therapy: INTERCEPT-TT - PubMed
Additional treatment with TAS-102 after adjuvant chemotherapy in CRC patients with ctDNA-defined MRD can induce ctDNA clearance but this may be transient without long-term cures.

Delighted to visit National Cancer Center Hospital East In Tokyo and connect with dear colleagues. Wonderful updates from SCRUM and MONSTAR program, led by Dr. Yoshino and kindly hosted by Dr. Bando. Looking forward to more collaborations on MRD! #crcsm

Updated precemtabart tocentecan (M9140, CEACAM ADC) data in mCRC presented at ASCO '25: 31% response rate and mPFS of 6.9m in 100% irinotecan pretreated patients. ADCs can overcome TOP1 relative resistance. https://ascopubs.org/doi/10.1200/JCO.2025.43.16_suppl.3038 #crcsm

Precemtabart tocentecan, an anti-CEACAM5 ADC, is active in heavily pretreated metastatic colorectal cancer—median PFS is 6.9 months, and 72% disease control at 12 weeks. First CRC cohort reported in @NatureMedicine. #crcsm
