Effect of E7777 Immunogenicity on Pharmacokinetics, Efficacy, and Safety in Adult Patients With Relapsed or Refractory Cutaneous T-Cell Lymphoma.
Trial report in Clinical and translational science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
E7777 is a therapeutic recombinant fusion protein comprised of diphtheria toxin fragments and human interleukin-2 (IL-2). Treatment with E7777 generates anti-drug antibodies (ADA). E7777-G000-302 assessed the efficacy and safety of E7777 in patients with relapsed or refractory cutaneous T-cell lymphoma (CTCL). Here, we describe the association between E7777 (at 9 μg/kg) and ADAs, and its effect on pharmacokinetics (PK), efficacy, and safety. Of 91 patients with immunogenicity results at baseline, 78.0% and 5.5% had preexisting anti-E7777 (E-ADAs) and anti-IL-2 antibodies (I-ADAs), respectively. The prevalence of E-ADAs and I-ADAs peaked at C3D1 (median titer 650,175) and C8D1 (median titer 32,805), respectively. However, I-ADA fold increases (1312-fold) were higher than E-ADA increases (181-fold). ADAs' effect on PK was assessed after treatment. E7777 reached C
