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

backgroundImatinib is the current standard frontline therapy for chronic myelogenous leukemia (CML). In the majority of patients, imatinib induces a complete cytogenetic response (CCyR); however, complete molecular responses are infrequent. The Bcr-Abl fusion creates a unique sequence of amino acids that could constitute a target for immunomodulation.

methodsA mixture of heteroclitic and native peptides derived from both b3a2 and b2a2 sequences was used to vaccinate patients with CML in CCyR who were receiving imatinib therapy and who had stable Bcr-Abl transcript levels.

resultsTen patients were enrolled, all with b2a2 transcripts (including 2 patients who had coexpression of b2a2 and b3a2). Patients had received imatinib for a median of 62 months. Three of 10 patients achieved 1-log reduction in Bcr-Abl transcript levels, including the 2 patients who had received previous interferon therapy, and 3 other patients achieved a major molecular response. The vaccine was tolerated well, and there were no grade > or =3 adverse events. Vaccination did not affect the leukocyte profiles in peripheral blood except for regulatory T cells, which were down-regulated briefly during the late stage of vaccination in patients who achieved approximately 1-log reduction in Bcr-Abl transcript levels.

conclusionsThe current data suggested that vaccination-related transient disruption of immune tolerance may contribute to the reduction in Bcr-Abl transcripts. Clinically, this Bcr-Abl peptide vaccine may transiently improve the molecular response in a subset of patients with CML.
