Abstract 1507TiP

Background

T-DXd is a HER2-directed antibody-drug conjugate available for the treatment of pts with metastatic NSCLC with activating HER2 mutations, HER2+ breast or gastric cancer, or HER2-low breast cancer. DESTINY-Lung01 showed efficacy of T-DXd monotherapy in heavily pretreated pts with unresectable/metastatic, HER2-OE, nonsquamous NSCLC. In preclinical studies, the combination of T-DXd and immunotherapy was more effective than either therapy alone, and the addition of chemotherapy may improve efficacy. This trial is evaluating T-DXd alone or in combination with durvalumab (durva) or MEDI5752 (a PD-1/CTLA-4 bispecific antibody) with or without chemotherapy in pts with unresectable/metastatic, HER2-OE, nonsquamous NSCLC.

Trial design

DESTINY-Lung03 (NCT04686305) is a phase 1b, open-label, multicenter, dose-escalation and -expansion study in pts with HER2-OE unresectable, locally advanced or metastatic, nonsquamous NSCLC. In part 1 (enrollment completed), pts with disease progression after 1 or 2 lines of systemic therapy in the recurrent/metastatic setting receive T-DXd monotherapy or T-DXd + durva in combination with cisplatin, carboplatin, or pemetrexed. Part 2 of the trial was not initiated. In part 3, pts who have not received prior treatment for advanced or metastatic disease will receive T-DXd in combination with MEDI5752, with or without carboplatin; pts in this phase must not have a history of prior immunotherapy for early disease and must lack activating EGFR mutations, an EML4-ALK fusion, or other targetable alterations. The primary endpoint is the frequency of adverse events (AEs) and serious AEs (SAEs) with T-DXd + durva + chemotherapy (part 1) or T-DXd + MEDI5752 ± chemotherapy (part 3). Secondary endpoints include confirmed objective response rate, duration of response, disease control rate, progression-free and overall survival, pharmacokinetics, and immunogenicity in all arms as well as the frequency of AEs and SAEs with T-DXd monotherapy (part 1).
