Phase I/II study of bevacizumab with BKM120, an oral PI3K inhibitor, in patients with refractory solid tumors (phase I) and relapsed/refractory glioblastoma (phase II).
Trial report in Journal of neuro-oncology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 36 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
backgroundCurrent bevacizumab-based regimens have failed to improve survival in patients with recurrent glioblastoma. To improve treatment efficacy, we evaluated bevacizumab + BKM120, an oral pan-class I PI3K inhibitor, in this patient population.
methodsA brief phase I study established the optimal BKM120 dose to administer with standard-dose bevacizumab. BKM120 60 mg PO daily + bevacizumab 10 mg/kg IV every 2 weeks in 28-day cycles was then administered to patients with relapsed/refractory glioblastoma in the phase II portion.
resultsEighty-eight patients enrolled (phase I, 12; phase II, 76). In phase I, BKM120 80 mg PO daily produced dose limiting toxicity in 3 of 6 patients; a BKM120 dose of 60 mg PO daily was established as the maximum tolerated dose. In phase II, the median progression-free survival (PFS) was 4.0 months (95% CI 3.4, 5.4), PFS at 6 months was 36.5%, and the overall response rate was 26%. Forty-two patients (57%) experienced one or more serious treatment related toxicities. The most common CNS toxicities included mood alteration (17%) and confusion (12%); however, these were often difficult to classify as treatment- versus tumor-related.
conclusionsThe efficacy seen in this study is similar to the efficacy previously reported with single-agent bevacizumab. This regimen was poorly tolerated, despite the low daily dose of BKM120. Further development of this combination for the treatment of glioblastoma is not recommended.
