Abstract | BACKGROUND: METHODS: This was a non-randomised, open-label, dose escalation and dose expansion trial. Patients harbouring molecular alterations of the PI3K/AKT/mTOR pathway received once daily (QD) oral LY2780301 (400 or 500 mg) in combination with intravenous gemcitabine (750 or 1000 mg/m2) on days 1, 8 and 15 of a 28-d cycle. Dose escalation followed a 3 + 3 design. Assessments included adverse events (AEs), PK and preliminary antitumour activity. RESULTS: Fifty patients (median age, 53 years; 74% female) predominantly with mutations/amplifications of PI3K (60%) and phosphatase and tensin homologue (PTEN) gene/ protein inactivation (42%) were treated for up to 14 cycles. The MTD was LY2780301 500 mg QD with gemcitabine 750 mg/m2. DLTs during cycle 1 were grade IV thrombocytopenia, grade III skin rash and grade III increase in alkaline phosphatase, gamma glutamyltransferase and alanine aminotransferase, occurring in one patient each. Most common AEs were anaemia (84%), fatigue (84%), transaminase increase (74%), thrombocytopenia (74%), nausea/ vomiting (70%), neutropenia (68%) and lymphopenia (56%). Among the efficacy-evaluable population, two patients (5%) had a partial response; the disease control rate was 74% at cycle 2. CONCLUSIONS: Addition of LY2780301 to gemcitabine showed manageable toxicity and encouraging antitumour activity in patients with molecular alterations of the PI3K/AKT/mTOR pathway.
