Tumor control and immune activation through palliative irradiation and ATR inhibition, PATRIOT Part C: a phase Ib trial.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Ataxia telangiectasia and Rad3-related kinase (ATR) is a rational radiosensitization target. In this study, we explore the combination of the ATR inhibitor, ceralasertib, and palliative radiotherapy, with primary endpoint the identification of maximum tolerated dose, and secondary endpoints the determination of adverse event causality, pharmacokinetics (PK) and anti-tumor activity. Twenty-seven patients were dosed in escalating dose cohorts from 20 to 80 mg twice daily (BD) with concomitant radiation, 20 Gy in 10 fractions or 30 Gy in 15 fractions. Patients were assessed for acute and late toxicities and response after therapy. A non-tolerated dose was not reached. Maximum administered dose was 80 mg BD ceralasertib over 3 weeks with 30 Gy in 15 fractions, at which 1/6 evaluable patients had dose-limiting toxicities (radiation dermatitis and mucositis). PK was comparable to monotherapy. Of 23 efficacy-evaluable participants, 2 (9%) had complete response (CR), 6 (26%) partial response (PR), 13 (57%) stable disease (SD) and 2 (9%) progressive disease (PD) as best response in irradiated tumors. Response was not clearly linked to genomic aberrations. Increased T and natural killer cell activation as observed in peripheral blood as treatment progressed.
