The Food and Drug Administration pooled analysis of overall survival according to depth of response in frontline advanced immune-oncology renal cell carcinoma trials.
Article in JNCI cancer spectrum, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRetrospective analyses of studies of IO-containing combinations for advanced renal cell carcinoma (RCC) suggest that depth of response is associated with overall survival but have methodological limitations. We investigated the relationship of week 12 depth of response as a continuous variable with overall survival.
methodsPooling data from patients with treatment-naïve advanced RCC enrolled in randomized IO-containing frontline advanced RCC trials submitted to the US Food and Drug Administration that included week 12 imaging assessment, we developed 36-month overall survival prediction models based on week 12 depth of response (reduction from baseline in target lesion diameter) using Cox proportional hazards with natural spline in an IO combination group and a sunitinib group. To avoid guarantee-time bias, only patients in follow-up at the week 12 scan were included. Overall survival was defined from the week 12 imaging date.
resultsAmong the 4 trials that met our inclusion criteria, 1364 patients in the IO combination group and 1267 patients in the sunitinib group had week 12 imaging. Depth of response and 36-month overall survival were correlated throughout the entire range of depth of response in both treatment groups, with no plateau in overall survival as depth of response approached complete response. Across this range, estimated 36-month overall survival was higher in the IO combination group.
conclusionsDeeper response was associated with better 36-month overall survival in this pooled exploratory analysis of treatment-naïve patients with advanced RCC treated with IO combination or sunitinib. Further work characterizing the relationship between depth of response and overall survival at the trial level may advance understanding of the utility of depth of response as a pharmacodynamic response biomarker or early endpoint in signal-seeking trials and to facilitate efficient drug development.
