Penpulimab combined with rituximab, high-dose methotrexate, and cytarabine (Pen-RMA) in newly diagnosed primary central nervous system lymphoma (PCNSL): a phase 2 trial.
Trial report in Blood cancer journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05347641 (A Single-arm, Prospective, Single-center, Phase II Clinical Study of Penpulimab Combined With RMA in the Treatment of Newly Diagnosed Primary CNS 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.

Abstract
This clinical trial (NCT05347641) evaluated efficacy and safety of penpulimab combined with rituximab, high-dose methotrexate, and cytarabine (Pen-RMA) in patients with newly diagnosed (ND) primary central nervous system lymphoma (PCNSL). Patients received an induction treatment of six cycles of Pen-RMA every 3 weeks. Patients younger than 60 years who achieved at least partial remission (PR) underwent autologous stem cell transplantation (ASCT), followed by 8 cycles of penpulimab as maintenance therapy. For patients over 60 years or not eligible for ASCT who achieved complete remission (CR) after induction therapy received 8 cycles of penpulimab as maintenance treatment, and those who achieved PR were treated with whole brain radiotherapy (WBRT) combined with 8 cycles of penpulimab. Patients who achieved stable disease (SD) or progressive disease (PD) were withdrawn from this study. The primary endpoint was 2-year progression-free survival (PFS). Between April 2022 and December 2023, twenty-six ND-PCNSL patients were enrolled, and 23 patients were included in the intention-to-treat analysis. The median age was 65 (38‒74) yr. The overall response rate (ORR) and CR rate after the induction therapy were 95.7% and 91.3%, respectively. At a median follow-up of 29.4 months, the median PFS and overall survival (OS) were not reached. 2-year PFS and OS were 70.7% and 75.0%, respectively. The most frequent treatment-related adverse events were leukopenia, anemia, neutropenia, and thrombocytopenia. Grade 3 or worse treatment-related adverse events occurred in 7 (30.4%) of 23 patients. Cerebrospinal fluid (CSF) circulating-tumor DNA (ctDNA) monitoring was performed in 13 patients with imaging CR and 1 with PR after induction treatment. Among them, 8 had CSF ctDNA clearance while 6 were positive. Overall, Pen-RMA regimen demonstrated encouraging antitumor activity with a manageable toxicity in PCNSL.
