Characteristics of relapsed/refractory diffuse large B-cell lymphoma patients with durable responses to maveropepimut-S, pembrolizumab, and cyclophosphamide: Long-term follow-up from the SPiReL trial.
Article in EJHaem, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03349450 (Phase 2 Study of an Immune Therapy, DPX-Survivac With Low Dose Cyclophosphamide Administered With Pembrolizumab in Patients With Persistent or Recurrent/Refractory Diffuse Large B-Cell Lymphoma), which is not on this map.

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

Abstract
Introduction: Patients with relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) have an unmet medical need. The objective of this trial was to assess the efficacy and toxicities of a novel triple immunotherapy regimen-pembrolizumab, low-dose cyclophosphamide, and maveropepimut-S (MVP-S). This regimen was designed to activate tumor-specific T cells by targeting the tumor-associated antigen survivin with MVP-S and reducing two important T cell inhibitory pathways: T cell exhaustion and regulatory T cells with pembrolizumab and metronomic cyclophosphamide, respectively. Methods: This was a single-arm Phase II clinical trial in 25 participants with R/R DLBCL-SPiReL trial (NCT03349450). Results: The median overall survival was 10.1 months and a third of participants survived over 2 years. Enhanced long-term survival was associated with favorable clinical characteristics and enhanced immune reactivity, as assessed by ELISpot and ISR-immune reactive responses. The regimen was well-tolerated with minimal Grade 3-4 toxicities. Conclusion: Combination immunotherapy regimens such as this could offer a promising alternative to other treatments with significant toxicities for select patients.
