Feasibility of enzalutamide on patients with recurrent non-muscle-invasive bladder cancer with marker tumors: phase I study.

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
objectiveRecent preclinical and retrospective clinical evidence shows that androgen receptor (AR)-mediated signals have significant roles in development of non-muscle invasive bladder cancer (NMIBC). Here, we conducted a single-center, phase I study to assess the feasibility and efficacy of enzalutamide in patients having recurrent NMIBC with marker tumors. Patients with NMIBC who cannot achieve complete transurethral resection (TUR) or with recurrence within a year after the TUR, were enrolled. The patients were administered oral enzalutamide at 160 mg dose, once daily for four weeks. Clinical response at the end of the treatment was evaluated using cystoscopy.
resultsOf the six patients enrolled, two experienced multiple recurrences. All the patients received the planned administration of enzalutamide. Enzalutamide was tolerable and all patients were able to complete the planed treatment, although four patients experienced mild treatment-related adverse events (AEs), but AEs with grade 2 or more were not observed. As for efficacy, three patients showed no change while the remaining three showed disease progression. Immunohistochemical analysis did not showed the strong staining of AR in the latest tumors. This is the first clinical study on enzalutamide treatment for NMIBC patients. In this study, four weeks of enzalutamide administration was well tolerated, however showed no clinical response for non-strong staining of AR.
