The primary endpoint is event-free survival; pathological complete response, a key secondary endpoint, was 48.6 percent with atezolizumab and 44.4 percent without (odds ratio 1.18, 0.74 to 1.89, p 0.48). Serious adverse events and liver transaminase abnormalities were more frequent with atezolizumab. PD-L1 expression was the strongest predictor of pathological complete response (odds ratio 2.08). The trial is unusual in omitting anthracyclines from the neoadjuvant phase, which is one explanation offered for the smaller immunotherapy effect than in KEYNOTE-522 and IMpassion031; event-free survival follow-up continues and no primary result was indexed in September 2026.","status":"negative","asOf":"2026-09-24","links":[{"label":"ClinicalTrials.gov NCT02620280","url":"https://clinicaltrials.gov/study/NCT02620280"},{"label":"Gianni et al., Annals of Oncology 2022: NeoTRIP pathological complete response","url":"https://doi.org/10.1016/j.annonc.2022.02.004"}],"tags":[],"related":[],"cancers":["tnbc","tnbc-early"],"sections":[],"technologies":["checkpoint-inhibitor","platinum","cytotoxic-chemotherapy"],"targets":[],"drugs":["atezolizumab","carboplatin","nab-paclitaxel"],"companies":[],"institutions":["fondazione-michelangelo"],"pathways":[],"terms":["pcr","efs"],"trials":["impassion031","keynote-522","gepardouze"],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"nct":"NCT02620280","phase":"3","setting":"Early high-risk or locally advanced triple-negative breast cancer: neoadjuvant carboplatin and nab-paclitaxel with or without atezolizumab for eight cycles, then adjuvant anthracycline, Europe and Taiwan","sponsor":"Fondazione Michelangelo","result":"pCR 48.6% vs 44.4% (OR 1.18, p 0.48), not significant; EFS (primary) awaited.","yearReported":2022,"enrolled":278,"enrolledBasis":"registry","outcomes":[{"endpoint":"Pathological complete response (breast and nodes)","unit":"%","arms":[{"name":"Carboplatin + nab-paclitaxel + atezolizumab","n":138,"value":48.6},{"name":"Carboplatin + nab-paclitaxel","n":142,"value":44.4}],"p":"0.48 (odds ratio 1.18, 0.74 to 1.89; event-free survival is the primary endpoint)","source":"https://doi.org/10.1016/j.annonc.2022.02.004"}],"replication":"Contrasts with KEYNOTE-522 and IMpassion031, which used anthracycline-containing backbones and showed pCR gains with checkpoint inhibition."},"route":"/trials/neotrip/","neighbours":{"cancer":[{"id":"tnbc-early","kind":"cancer","name":"Early triple-negative breast cancer","route":"/cancers/tnbc-early/"},{"id":"tnbc","kind":"cancer","name":"Triple-negative breast cancer (TNBC)","route":"/cancers/tnbc/"}],"technology":[{"id":"cytotoxic-chemotherapy","kind":"technology","name":"Cytotoxic chemotherapy","route":"/technologies/cytotoxic-chemotherapy/"},{"id":"checkpoint-inhibitor","kind":"technology","name":"Immune checkpoint inhibitors","route":"/technologies/checkpoint-inhibitor/"},{"id":"platinum","kind":"technology","name":"Platinum agents","route":"/technologies/platinum/"}],"drug":[{"id":"atezolizumab","kind":"drug","name":"Atezolizumab","route":"/drugs/atezolizumab/"},{"id":"carboplatin","kind":"drug","name":"Carboplatin","route":"/drugs/carboplatin/"},{"id":"nab-paclitaxel","kind":"drug","name":"Nab-paclitaxel","route":"/drugs/nab-paclitaxel/"}],"institution":[{"id":"fondazione-michelangelo","kind":"institution","name":"Fondazione Michelangelo","route":"/institutions/fondazione-michelangelo/"}],"term":[{"id":"efs","kind":"term","name":"Event-free / disease-free survival (EFS, DFS, iDFS, RFS)","route":"/terms/efs/"},{"id":"pcr","kind":"term","name":"Pathologic complete response (pCR)","route":"/terms/pcr/"}],"trial":[{"id":"barbican","kind":"trial","name":"BARBICAN","route":"/trials/barbican/"},{"id":"gepardouze","kind":"trial","name":"GeparDouze / NSABP B-59","route":"/trials/gepardouze/"},{"id":"impassion031","kind":"trial","name":"IMpassion031","route":"/trials/impassion031/"},{"id":"impassion130","kind":"trial","name":"IMpassion130","route":"/trials/impassion130/"},{"id":"keynote-522","kind":"trial","name":"KEYNOTE-522","route":"/trials/keynote-522/"}]}}
