1 · What the graph read from 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.

2 · The registry

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

backgroundHand-foot skin reaction (HFSR) induced by multiple tyrosine kinase inhibitors (TKIs) is a serious side effect that can cause treatment interruption or decreased dosing. This study was conducted to evaluate the safety and efficacy of bis-glyceryl ascorbate (Amitose bis(di)-glyceryl ascorbate [DGA])-containing cream (DGA cream) for the prevention of sunitinib-induced HFSR.

methodsA single-arm, open-label phase I/II study was conducted, targeting patients with metastatic renal cell carcinoma (mRCC) who were receiving sunitinib therapy with a schedule of 2 weeks on/1 week off. The participants applied DGA cream to both palmar and plantar surfaces in combination with a moisturizing agent as standard-of-care prophylaxis during two sunitinib treatment cycles (6 weeks). The primary endpoint in phase I was safety defined as dermatological abnormalities and it was determined in the first five participants. The primary endpoint in phase II was efficacy defined as development of grade 1 or higher HFSR defined by Common Terminology Criteria for Adverse Events within 6 weeks and it was determined on a full analysis set (FAS) defined as the population including all participants who used DGA cream once in the study duration. Efficacy in the per protocol set (PPS) defined as the population excluding seven patients whose study treatment was interrupted was evaluated as a secondary endpoint.

resultsTwenty-four patients were enrolled as a FAS. No dermatological abnormalities occurred in the first 5 patients enrolled in the phase I study. Three patients developed HFSR (grade 1: n = 2, grade 2: n = 1) in the observation period. The HFSR incidence rate was 12.5% (3/24; 95% confidence interval [CI]: 2.7%-32.4%) in the FAS, which was significantly lower than the incidence rate predefined as a threshold of 33.3% by a previous report from our hospital (P = .030). The incidence rate in the 17 patients of the PPS was 17.6% (3/17; 95%CI: 3.8%-43.4%).

conclusionDGA cream may be safe and effective in the prophylaxis of HFSR in mRCC patients who receive sunitinib therapy (Trial ID: jRCTs051180051).
