Capivasertib plus fulvestrant in patients with HR-positive/HER2-negative advanced breast cancer: phase 3 CAPItello-291 study extended Chinese cohort.
Trial report in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04305496 (A Phase III Double-blind Randomised Study Assessing the Efficacy and Safety of Capivasertib + Fulvestrant Versus Placebo + Fulvestrant as Treatment for Locally Advanced), which is not on this map.

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.

Abstract
In the global CAPItello-291 randomized phase 3 study (NCT04305496) in patients with hormone receptor-positive/HER2-negative advanced breast cancer and progression during/after aromatase inhibitor treatment, capivasertib-fulvestrant significantly improved progression-free survival (PFS) in the overall population and patients with PIK3CA/AKT1/PTEN-altered tumors versus placebo-fulvestrant. We assessed efficacy and safety of capivasertib-fulvestrant in a prespecified exploratory analysis of a Chinese cohort (n = 24) and extended study with the same protocol (n = 110). Clinically meaningful PFS benefit for capivasertib-fulvestrant was observed in the overall population (median PFS: 6.9 [capivasertib-fulvestrant] versus 2.8 [placebo-fulvestrant] months; hazard ratio 0.51, 95% CI 0.34-0.76), patients with PIK3CA/AKT1/PTEN-altered tumors (n = 46; 5.7 versus 1.9 months; hazard ratio 0.41, 95% CI 0.19-0.85) and PIK3CA/AKT1/PTEN-non-altered tumors (patients with confirmed next-generation sequencing results [n = 68]; 9.2 versus 2.7 months; hazard ratio 0.38; 95% CI 0.21-0.68). The most frequent adverse events (AEs) with capivasertib-fulvestrant were diarrhea (60.6% versus 11.3% with placebo-fulvestrant) and hyperglycemia (57.7% versus 17.7%). AEs leading to capivasertib-fulvestrant discontinuation were reported in 11.3% of patients versus 3.2% for placebo-fulvestrant. The benefit-risk profile of capivasertib-fulvestrant in the Chinese cohort was favorable; further exploration in patients with PIK3CA/AKT1/PTEN-non-altered tumors is warranted.
