A Phase II Pilot Study of Anti-PD-L1, Durvalumab, and a PARP Inhibitor, Olaparib in Patients With Metastatic Triple-Negative Breast Cancer With or Without Germline BRCA Mutation.
Trial report in Cancer medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02484404 (Phase I/II Study of the Anti-Programmed Death Ligand-1 Antibody Durvalumab), which is not on this map. Cited by 2 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.

Abstract
backgroundImmunostimulatory effects of PARP inhibitors could increase sensitivity to immune checkpoint inhibitors. The previous Phase II trial (MEDIOLA) reported clinical benefits of durvalumab and olaparib (D + O) in patients with germline BRCA-mutated (gBRCAm) HER2-negative metastatic breast cancer. Yet, the clinical activity of D + O in germline BRCA wild-type (gBRCAwt) triple-negative breast cancer (TNBC) remains unknown.
methodsThis single-arm Phase II study tested D + O in patients with metastatic TNBC. The primary objective was overall response rate (ORR). Secondary objectives were safety, disease control rate (DCR), progression-free survival (PFS) and overall survival (OS). Based on gBRCA status, patients were assigned to either gBRCAwt or gBRCAm cohort and were treated with D (1500 mg iv q4w) and O (300 mg twice a day orally). Pretreatment fresh tissues and serial blood samples were collected for correlative studies.
resultsFifteen patients (12 gBRCAwt and 3 gBRCAm) were enrolled. gBRCAm and gBRCAwt cohorts are reported as a combined dataset because of small sample size due to COVID-19 and slow accrual. The median number of prior therapies was three (range 0-8). Among 14 RECIST-evaluable patients (11 gBRCAwt and 3 gBRCAm), ORR was 28.6% (3 gBRCAm and 1 gBRCAwt). DCR was 64.3% (3 gBRCAm and 6 gBRCAwt). The median PFS and OS were 3.6 months (95% confidence interval [CI]: 1.8-5.7) and 10.7 months (95% CI: 5.9-38.9), respectively. There is one gBRCAm patient with ongoing durable PR (67.4+ months). There was no new safety concern. CD83 expression on Types 1 and 2 conventional dendritic cells in blood at baseline was low in the patients with PFS ≥ 4 months compared to those with PFS < 4 months.
conclusionOur study demonstrated modest clinical benefits of D + O with ORR of 28.6% in subsets of heavily pretreated TNBC. Further detailed classification of DCs to understand the predictive role of DCs and prospective validation in a large cohort is required.
