A phase 1 study of buparlisib and bevacizumab in patients with metastatic renal cell carcinoma progressing on vascular endothelial growth factor-targeted therapies.
Article in Cancer, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
backgroundThe phosphatidylinositol-3 kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) pathway is dysregulated in patients with metastatic renal cell carcinoma (mRCC). Buparlisib is a pan-PI3K inhibitor with activity in advanced solid tumors. The primary objective of the current study was to determine the maximum tolerated dose (MTD) and dose-limiting toxicities of buparlisib and bevacizumab in patients with mRCC. Secondary objectives included efficacy, biomarker discovery, and additional toxicity.
methodsThis was a standard 3 + 3 dose escalation study of buparlisib (at a dose of 60-100 mg/day) and bevacizumab (at a dose of 10 mg/kg every 2 weeks). After the MTD was defined, 15 patients were accrued to the expansion cohort.
resultsThirty-two patients were accrued (3 were treated at 60 mg/day, 21 were treated at 80 mg/day, 6 were treated at 100 mg/day, and 2 patients never received therapy). The majority of patients had clear cell histology (87%) and 50% had received ≥2 prior lines of therapy. The MTD of buparlisib was 80 mg/day and that of bevacizumab was 10 mg/kg every 2 weeks. A total of 28 patients discontinued therapy: 17 because of disease progression, 7 because of toxicity, and 4 for other reasons. Dose-limiting toxicities included rash/pruritis, elevated lipase/amylase, anorexia, and psychiatric disorders (suicidal ideation, depression, and cognitive disturbances). Of the 30 patients who received at least 1 dose, 13% achieved a partial response (95% confidence interval, 4%-31%). Two patients harboring activating PI3KA mutations achieved 42% and 16% maximal tumor shrinkage, respectively.
conclusionsBuparlisib at a dose of 80 mg/day with bevacizumab was found to be a tolerable regimen with preliminary activity in vascular endothelial growth factor-refractory mRCC. The benefit of this combination may be of interest for future mRCC trials, possibly in a selected patient population. Cancer 2016;122:2389-2398. © 2016 American Cancer Society.
