The purpose of this study is to test the safety and effectiveness of a sequence of drugs (a Taxane plus Trastuzumab plus Pertuzumab followed by Trastuzumab Deruxtecan, followed by Tucatinib plus Ado-Trastuzumab Emtansine (T-DM1), followed by Trastuzumab plus Pertuzumab plus Tucatinib) in HER2+ Breast Cancer. The study will help investigators understand whether first intensifying therapy for a specific period and then stopping treatment is safe and effective for participants.

TransCon IL-2 β/γ is an investigational drug being developed for treatment of locally advanced or metastatic solid tumors. This is a first-in-human, open-label, Phase 1/2, dose escalation and dose expansion study of TransCon IL-2 β/γ as monotherapy or in combination therapy in adult participants with advanced or metastatic solid tumors. Given the unique PK profile enabled by the TransCon technology, TransCon IL-2 β/γ presents the opportunity to enhance the therapeutic index of current IL-2 therapy.
