Trial reportCancer medicine2021
A randomized, double-blind, phase II study of oral histone deacetylase inhibitor resminostat plus S-1 versus placebo plus S-1 in biliary tract cancers previously treated with gemcitabine plus platinum-based chemotherapy.
Trial report in Cancer medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
purposeEffective second-line chemotherapy options are limited in treating advanced biliary tract cancers (BTCs). Resminostat is an oral histone deacetylase inhibitor. Such inhibitors increase sensitivity to fluorouracil, the active form of S-1. In the phase I study, addition of resminostat to S-1 was suggested to have promising efficacy for pre-treated BTCs. This study investigated the efficacy and safety of resminostat plus S-1 in second-line therapy for BTCs.
methodsPatients were randomly assigned to receive resminostat or placebo (200 mg orally per day; days 1-5 and 8-12) and S-1 group (80-120 mg orally per day by body surface area; days 1-14) over a 21-day cycle. The primary endpoint was progression-free survival (PFS). Secondary endpoints comprised overall survival (OS), response rate (RR), disease control rate (DCR), and safety.
resultsAmong 101 patients enrolled, 50 received resminostat+S-1 and 51 received placebo+S-1. Median PFS was 2.9 months for resminostat+S-1 vs. 3.0 months for placebo+S-1 (HR: 1.154, 95% CI: 0.759-1.757, p = 0.502); median OS was 7.8 months vs. 7.5 months, respectively (HR: 1.049, 95% CI: 0.653-1.684, p = 0.834); the RR and DCR were 6.0% vs. 9.8% and 70.0% vs. 78.4%, respectively. Treatment-related adverse events (TrAEs) of grade ≥ 3 occurring more frequently (≥10% difference) in the resminostat+S-1 than in the placebo+S-1 comprised platelet count decreased (18.0% vs. 2.0%) and decreased appetite (16.0% vs. 2.0%).
conclusionsResminostat plus S-1 therapy improved neither PFS nor OS for patients with pre-treated BTCs. Addition of resminostat to S-1 was associated with higher incidence of TrAEs, but these were manageable (JapicCTI-183883).
