At the 2025 ASCO Annual Meeting, new data on IO-based combinations in mRCC emerged. For instance, Dr. Brian Rini, MD shared results from four trials. These were CheckMate 214, KEYNOTE-426, CheckMate 9ER, and CLEAR. Moreover, they compared immunotherapy regimens in kidney cancer. As a result, the findings help oncologists and cancer researchers. In fact, they improve survival and disease control in mRCC.
Key ASCO25 Data on IO-Based Combinations in mRCC
The trials showed major progress in mRCC treatment. Specifically, IO-based combinations in mRCC outperformed single-agent TKIs. Therefore, here are the key points for oncologists:
- Survival Gains: OS hazard ratios ranged from 0.71 to 0.79. In addition, the 6-year OS rates hit 40–46%.
- Ipi/Nivo’s Durability: CheckMate 214 reported a 6-year OS of 42% for Ipi/Nivo. Thus, this shows lasting disease control.
- IO-TKI Responses: The CLEAR trial had a 71% ORR with pembrolizumab plus lenvatinib. Furthermore, its PFS was 23.9 months.
- Trade-Offs: IO-TKIs improve ORR but Ipi/Nivo has a lower primary PD rate (8% vs. 12–18%). Consequently, this is a key trade-off for oncologists.
Challenges in mRCC Trial Comparisons
Cross-trial comparisons of IO-based combinations in mRCC are complex. For example, patient populations vary. Similarly, follow-up durations differ. Likewise, control arms perform inconsistently. In particular, prior nephrectomy rates and PD-L1 cut-offs vary. Therefore, cancer researchers must account for these factors. Ultimately, this ensures accurate treatment decisions.
Implications for mRCC Treatment
The ASCO25 data highlights personalized care in mRCC. Notably, IO-based combinations in mRCC offer diverse benefits. For instance, Ipi/Nivo ensures durability. On the other hand, IO-TKIs provide rapid tumor shrinkage. However, tolerability matters too. In fact, Ipi/Nivo has fewer chronic side effects like hand-foot syndrome.
