1L MSI-H/dMMR mCRC
Now FDA Approved
In the treatment of MSI-H/dMMR unresectable or metastatic CRC
Superior PFS vs an I-O monotherapy1*†
mPFS (dual primary endpoint): NR (95% CI: 53.8–NE) with OPDIVO + YERVOY vs 39.3 months (95% CI: 22.1–NE) with OPDIVO (HR=0.62 [95% CI: 0.48–0.81]; P=0.0003)1,2
*Nivolumab.1 †Checkmate 8HW also compared OPDIVO + YERVOY with investigator's choice chemotherapy, which included mFOLFOX6 (oxaliplatin, leucovorin, and fluorouracil) ± bevacizumab or cetuximab, or FOLFIRI (irinotecan, leucovorin, and fluorouracil) ± bevacizumab or cetuximab. PFS for OPDIVO + YERVOY vs chemotherapy in 1L patients is a dual primary endpoint.1,2
INDICATION OPDIVO® (nivolumab), in combination with YERVOY® (ipilimumab), is indicated for the treatment of adult and pediatric patients 12 years and older with unresectable or metastatic microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) colorectal cancer (CRC).
CHECKMATE 8HW: TREATMENT OF ADULT AND PEDIATRIC PATIENTS 12 YEARS AND OLDER WITH MSI-H/dMMR mCRC
The only phase 3 trial comparing OPDIVO + YERVOY with both OPDIVO and chemotherapy* in MSI-H/dMMR mCRC1
In Checkmate 8HW, a total of 839 patients were randomized to receive either OPDIVO + YERVOY, OPDIVO, or investigator's choice of chemotherapy1,2*†
- OPDIVO + YERVOY was assessed against OPDIVO in all lines; a majority (57%) of patients in the OPDIVO + YERVOY arm were 1L patients1
- Median follow-up for OPDIVO + YERVOY vs OPDIVO was 47.0 months (range: 16.7–60.5; data cutoff: 8/28/2024)1
- Median follow-up for OPDIVO + YERVOY vs chemotherapy was 31.5 months (range: 6.1–48.4; data cutoff: 10/12/2023)1
*Investigator’s choice chemotherapy included mFOLFOX6 (oxaliplatin, leucovorin, and [fluorouracil] FU) ± bevacizumab or cetuximab, or FOLFIRI (irinotecan, leucovorin, and FU) ± bevacizumab or cetuximab.1 †Efficacy analyses were performed on all randomized patients with centrally confirmed MSI-H/dMMR mCRC. In the OPDIVO + YERVOY vs OPDIVO comparison, 354 patients were randomized to OPDIVO + YERVOY and 353 patients to OPDIVO monotherapy. Of these patients, 296 OPDIVO + YERVOY patients and 286 OPDIVO patients with MSI-H/dMMR mCRC were centrally confirmed. In the OPDIVO + YERVOY vs chemotherapy comparison, 202 patients were randomized to OPDIVO + YERVOY and 101 patients to chemotherapy. Of these patients, 171 OPDIVO + YERVOY patients and 84 chemotherapy patients with MSI-H/dMMR mCRC were centrally confirmed.1 ‡Up to 2 years for the OPDIVO + YERVOY and OPDIVO monotherapy arms only.1 §Investigator’s choice of chemotherapy could be administered until disease progression or unacceptable toxicity.1 IIAll response and progression events were BICR-assessed per RECIST v1.1.1
1L=first-line; BICR=blinded independent central review; dMMR=mismatch repair deficient; ECOG PS=Eastern Cooperative Oncology Group Performance Status; IV=intravenous; mCRC=metastatic colorectal cancer; MSI-H=microsatellite instability-high; NE=not evaluable; ORR=overall response rate; OS=overall survival; PFS=progression-free survival; q2w=every 2 weeks; q3w=every 3 weeks; q4w=every 4 weeks; RECIST=Response Evaluation Criteria in Solid Tumors; TTR=time to response.

- Median DOT was 20.5 months in the OPDIVO + YERVOY arm and 16.4 months in the OPDIVO arm*†
- More patients in the OPDIVO + YERVOY (62.5%) arm had a duration of therapy >12 months than in the OPDIVO arm (54.1%)*†
