Trial Outcomes & Findings for Safety, Tolerability, and Immunoregulatory Activity of Mogamulizumab (KW-0761) in Subjects With Advanced and/or Metastatic Solid Tumors (NCT NCT02281409)

NCT ID: NCT02281409

Last Updated: 2021-04-23

Results Overview

A standard 3+3 design will be utilized to determine the MTD. Four dose levels of KW-0761 will be investigated (0.5mg/kg, 1mg/kg, 3mg/kg, 10mg/kg). Patients will be treated in cohorts of size three to six and the dosage will be escalated if the clinical toxicity is acceptable.

Measure
Cohort 1 (0.5 mg/kg KW-0761 IV)
Patients will be enrolled to receive a weekly intravenous (IV) dose of KW-0761 ranging from 0.5 mg/kg to 10.0 mg/kg as feasible starting on Day 1 for 4 weeks. In the absence of toxicity or progression of disease, patients may continue receiving KW-0761 for up to 12 months. Subsequent treatment courses will consist of an infusion every other week. Following end of treatment or treatment completion date, a 24-week short term follow-up (STFU) period of observation will begin. Phase II of the study will enroll a total of 48 subjects, 16 patients in 3 tumor-specific expansion cohorts each treated at the RP2D (MTD, or highest dose tested in Phase I part of trial).

Patients will be enrolled to receive a weekly intravenous (IV) dose of KW-0761 ranging from 0.5 mg/kg to 10.0 mg/kg as feasible starting on Day 1 for 4 weeks. In the absence of toxicity or progression of disease, patients may continue receiving KW-0761 for up to 12 months. Subsequent treatment courses will consist of an infusion every other week. Following end of treatment or treatment completion date, a 24-week short term follow-up (STFU) period of observation will begin. Phase II of the study will enroll a total of 48 subjects, 16 patients in 3 tumor-specific expansion cohorts each treated at the RP2D (MTD, or highest dose tested in Phase I part of trial).
