| ERBB3 mutant | invasive bladder transitional cell carcinoma | predicted - sensitive | Cisplatin + Gemcitabine + Sorafenib | Phase II | Actionable | In a Phase II trial, ERBB3 mutations were only detected in patients with muscle-invasive urothelial bladder cancer that responded to Nexavar (sorafenib), Platinol (cisplatin) and Gemzar (gemcitabine) combination therapy (J Clin Oncol 35, 2017 (suppl 6S; abstract 345)). | detail... |
| ERBB3 mutant | Advanced Solid Tumor | no benefit | Neratinib | Phase II | Actionable | In a Phase II trial (SUMMIT), Nerlynx (neratinib) treatment resulted in no objective response, a clinical benefit rate of 12.5% (2/16), and a median progression-free survival of 1.7 months in patients with advanced solid tumors harboring ERBB3 (HER3) mutations (PMID: 29420467; NCT01953926). | 29420467 |
