Treatment Efficacy and Molecular Dynamics of Neoadjuvant Durvalumab and Olaparib in Resectable Urothelial Bladder Cancer: The NEODURVARIB Trial.

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
purposeNeoadjuvant treatment of bladder cancer is evolving, with immunotherapy demonstrating promising activity. PARP inhibition combined with immune activation has been proposed as a synergistic strategy. We conducted a comprehensive molecular characterization of tumors treated with this combination in the neoadjuvant setting to provide crucial results for rational development. PATIENTS AND
methodsA phase II clinical trial was designed to evaluate the combination of anti-PDL1 inhibitor durvalumab and PARP inhibitor olaparib, focusing on biomarker dynamics in both pre- and post-treatment settings. A total of 29 patients were enrolled. Genomic and transcriptomic profiling, as well as analyses of immune cell populations, was conducted at baseline and at the time of cystectomy.
resultsOf the 29 patients treated, a pathologic complete response was observed in 13 cases (44.8%). No major safety concerns were associated with the treatment, and 26 patients (90%) underwent cystectomy. Mutational patterns, tumor mutation burden, and homologous recombination deficiency remained stable throughout treatment and were not predictive of outcomes. However, a shift toward stromal phenotypes and increased expression of epithelial-mesenchymal transition signatures were observed following therapy, particularly in resistant tumors. Moreover, an increase in circulating CD4+ CD27- CD28- T cells was noted among responders.
conclusionsThe combination of neoadjuvant durvalumab and olaparib shows therapeutic activity in bladder cancer. Resistance mechanisms seem to be driven by transcriptional adaptations rather than the emergence of new mutations.
