Solid Tumors Harboring Somatic HER2 or EGFR Exon 18 Mutations | Drug: Neratinib Drug: Fulvestrant Drug: Trastuzumab | Phase 2 |
This is an open-label, multicenter, multinational, Phase 2 basket study exploring the efficacy and safety of neratinib as monotherapy or in combination with other therapies in participants with HER (EGFR, HER2) mutation-positive solid tumors. The study has a basket design and includes several cohorts, either defined by an actionable somatic mutation or by actionable mutation and tumor histology, including HER2 mutant breast, HER2 mutant cervical, HER2 mutant salivary gland, and EGFR Exon 18 mutant Non-small cell lung cancers.
The trial will consist of a screening period, a treatment period, and an end of treatment visit occurring when neratinib is discontinued for any reason, a safety follow-up visit occurring 28 days after the last dose of neratinib and a survival follow-up period.
