Phase 1

Conditions
Locally Advanced or Metastatic Non-Small Cell Lung Cancer
Interventions
Registration Number
NCT04686305
Lead Sponsor

Brief Summary

DESTINY-Lung03 will investigate the safety and tolerability of trastuzumab deruxtecan in combination with Immunotherapy Agents with and without chemotherapy in patients with HER2 over-expressing non-small cell lung cancer. The efficacy will be also analyzed as a secondary endpoint.

Detailed Description

Part 1 is a dose escalation study by design, allowing the assessment of safety, tolerability and recommended dose levels of the combination of T-DXd and durvalumab plus cisplatin, carboplatin or pemetrexed. No more patients will be enrolled in this part of the study. Part 2, expansions in the treatment naïve setting on any recommended dose level will not be initiated. The evaluation of T-DXd combination treatment with immunotherapy continues in Part 3 and Part 4, assessing T-DXd and volrustomig with carboplatin (Arm 3B) or without carboplatin (Arm 3A) and T-Dxd and rilvegostomig with carboplatin (Arm 4B) or without carboplatin (Arm 4A).

For Part 3, patients will be randomized to Arms 3A and 3B, beginning with the cohorts receiving the volrustomig starting dose (SD). A total of 6 DLT-evaluable patients will be enrolled to the SD cohorts in each arm. If the combination of T-DXd with volrustomig at the starting dose is deemed safe, a dose escalation (E1) cohort will be opened for 6 DLT-evaluable patients. Once all open dose confirmation cohorts have 6 DLT-evaluable patients, the SRC will convene to select the volrustomig RP2D to be used in the dose-expansion (DE) cohorts of each arm (n=34).

In Part 4, once a total of 6 DLT-evaluable patients/arm have been enrolled into Arm 4A and Arm 4B safety-run in (SR) cohorts and deemed safe, an additional 34 patients per arm will be enrolled in Arms 4A and 4B in dose expansion cohorts.

The target population of interest (for Part 3 and Part 4) are patients with advanced or metastatic non-small cell lung cancer measurable disease by RECIST 1.1 criteria, HER2 overexpression, ECOG PS of 0 to 1, patients who are treatment naïve for recurrent, unresectable or metastatic disease. Patients with tumors that harbor a known genomic alteration or driver for which approved therapies are available are excluded.
