PI3Kδ Inhibitor Parsaclisib in Japanese Patients With Relapsed or Refractory Follicular Lymphoma.
Trial report in Cancer science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04434937 (A Phase 2, Multicenter, Open-Label Study of Parsaclisib, a PI3Kδ Inhibitor, in Japanese Participants With Relapsed or Refractory Follicular 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
Follicular lymphoma (FL) is the second most common subtype of non-Hodgkin lymphoma (NHL) in Japan, the United States, and Western Europe. Parsaclisib is a potent, selective next-generation PI3Kδ inhibitor that has demonstrated clinical efficacy and tolerability in phase II studies of patients with relapsed or refractory (R/R) B-cell NHL, including FL. We report results from CITADEL-213 (NCT04434937), a phase II study evaluating the efficacy and safety of parsaclisib in Japanese patients with R/R FL. Eligible patients were aged ≥ 18 years with histologically confirmed R/R FL (grade 1, 2, or 3a), had received two or more prior systemic therapies, and were ineligible for hematopoietic stem cell transplantation. Patients received parsaclisib 20 mg once daily for 8 weeks, followed by parsaclisib 2.5 mg once daily thereafter. The primary endpoint was the objective response rate (ORR). At the data cut-off (February 16, 2023), 42 patients had received treatment with parsaclisib, of whom 41 were evaluable for change in target tumor size. Median (range) age at baseline was 66.5 (52-87) years. ORR (95% confidence interval [CI]) was 88.1% (74.4-96.0), with 10 patients (23.8%) experiencing a complete response and 27 patients (64.3%) experiencing a partial response. Median (95% CI) duration of response was not reached (8.0 months-not estimable). The most common treatment-emergent adverse events (TEAEs) were diarrhea (28.6%; grade ≥ 3, 7.1%) and stomatitis (23.8%; grade ≥ 3, 11.9%); TEAEs led to parsaclisib discontinuation in five patients (11.9%). There were no fatal TEAEs. In conclusion, parsaclisib monotherapy demonstrated durable responses with a manageable safety profile in Japanese patients with R/R FL.
