Abstract 4584

Background

VEGF-targeted therapies are the cornerstone of first and subsequent lines of therapy in ccRCC; however, resistance develops almost invariably. Another proven therapeutic intervention in ccRCC is treatment with the allosteric mTOR inhibitor everolimus, which only partially inhibits TORC1 and thus results in increased phosphorylation of Akt and paradoxical hyperactive signalling. TAK-228, a highly selective ATP-competitive TORC1 and TORC2 inhibitor, has shown promising antitumor activity and acceptable safety in ccRCC. In a pooled analysis of 2 prior studies of 41 patients (pts) with ccRCC, TAK-228 treatment resulted in 1 CR, 5 PR and 21 pts with SD; 13 pts who achieved ≥SD had prior treatment with a rapalog. The median duration of overall response was 250 d (range, 55–1614). The most common AEs were fatigue, nausea and hyperglycemia. Also, combination of TAK-228 with TAK-117, a selective inhibitor of PI3Kα, has shown more complete and prolonged inhibition of TORC1 and TORC2. This phase 2, open-label, randomized study will evaluate the efficacy and safety of TAK-228 and TAK-228+TAK-117 vs everolimus in pts with advanced or metastatic ccRCC that have progressed on or after VEGF-targeted therapy (NCT02724020).

Trial design

189 pts will be randomized 1:1:1 to TAK-228 30 mg once-weekly on d1, 8, 15, 22 with a light meal; TAK-228 4 mg once-daily (QD) + TAK-117 200 mg QD on d1–3, 8–10, 15–17, 22–24 on an empty stomach; or everolimus 10 mg QD, in 28-d cycles. Pts will be stratified by number of prior therapy lines and IMDC risk category. Pts with histologically confirmed advanced/metastatic ccRCC, ≥1 prior line of VEGF-targeted therapy with PD, KPS ≥70%, and adequate organ function, but no CNS metastasis or prior therapy with agents that target PI3K, AKT, or mTOR are eligible. Pts in the everolimus arm who progress may crossover. An interim futility analysis will be conducted after 30 pts in each arm have received 2 treatment cycles. Primary endpoint is PFS. Secondary endpoints are OS, TTP, ORR, CBR, safety, and QoL. As of January 24, 2017, 54 pts have been screened.
