Letrozole Monotherapy Falls Short in Ovarian Cancer Clinical Trial
The phase III NRG GY019 trial showed that letrozole monotherapy did not meet the non‑inferiority endpoint for progression‑free survival compared with the standard paclitaxel‑carboplatin followed by letrozole regimen in newly diagnosed low‑grade serous ovarian carcinoma. At a median 27.3‑month follow‑up, the hazard ratio for letrozole versus combination therapy was 1.30, exceeding the pre‑specified futility margin. Overall survival remained high in both arms (95% vs 92%), but the combination arm incurred markedly more grade 3‑4 adverse events. Sub‑analyses suggest a potential niche for letrozole alone in patients with no gross residual disease after surgery.
