KHK2455 Alone and in Combination With Mogamulizumab in Subjects With Locally Advanced or Metastatic Solid Tumors

Brief description of study

The purpose of this study is to characterize the safety, tolerability, and determine the maximum tolerated dose (MTD) or the highest protocol-defined dose, in the absence of exceeding the MTD, of KHK2455 administered orally in combination with mogamulizumab to subjects with locally advanced or metastatic solid tumors.

Detailed Study Description

The study is designed as a 2-part, multicenter, open-label, Phase 1, dose-escalation, cohort-expansion study of KHK2455 as a monotherapy run-in (Cycle 0) followed by combination therapy with the anti-CCR4 antibody mogamulizumab (Cycle 1 and beyond).

Part 1 will identify the MTD or the highest protocol-defined dose, in the absence of exceeding the MTD, for the KHK2455 monotherapy run-in and for the combination regimen (KHK2455 monotherapy [Cycle 0] followed by KHK2455 + mogamulizumab combination [Cycle 1]). The dose escalation phase (Part 1) will enroll up to approximately 36 subjects.

Part 2, the cohort-expansion phase, will further explore the safety, tolerability, PK, PD, pharmacogenomics (PGx), and preliminary anti-tumor activity of KHK2455 administered as monotherapy and in combination with mogamulizumab in subjects with one cohort-specific tumor type. In Part 2, approximately 15 subjects with a selected tumor type will be enrolled and treated with the recommended KHK2455 dose established in Part 1 in combination with mogamulizumab.
