Afuresertib plus fulvestrant for pretreated HR-positive, HER2-negative, advanced breast cancer: a phase Ib trial.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04851613 (A Phase Ib/III Study to Evaluate the Efficacy and Safety of Afuresertib Plus Fulvestrant in Patients With Locally Advanced or Metastatic HR+/HER2- Breast Cancer Who Failed Standard of Care Therapies), 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

Abstract
This single-arm, phase Ib trial evaluated the antitumor activities and safety of afuresertib (a pan AKT inhibitor) plus fulvestrant for previously treated HR-positive, HER2-negative advanced breast cancer. Eligible patients received afuresertib at 125 mg/day and fulvestrant at 500 mg on days 1, 15, and 29, and every 28 days thereafter during safety run-in and, in the absence of serious toxicities, subsequent 4-week cycles. The trial enrolled 31 patients (median age 54 years; 30 women); 20 received prior CDK4/6 inhibitor therapy. The primary endpoint of investigators-assessed objective response rate was 25.8% (8/31; 90% CI 13.5-41.8). Nine patients (29.0%) had grade 3 or worse adverse events. No death due to adverse event occurred. In conclusion, afuresertib plus fulvestrant was well-tolerated and had promising antitumor activities against pretreated, advanced HR-positive, HER2-negative breast cancer, supporting further studies with randomized controlled trials. This trial is registered with ClinicalTrials.gov (NCT04851613).
