Efficacy

The first Phase 3 study of a BTKi with and without obinutuzumab vs chemoimmunotherapy1 

A randomized, multicenter, open-label study in patients with previously untreated CLL2

Study design

CALQUENCE Study Design for ELEVATE-TN in Patients with Previously Untreated CLL.
CALQUENCE Study Design for ELEVATE-TN in Patients with Previously Untreated CLL.
  • Concomitant antithrombotics were allowed, with the exception of warfarin§2
  • Patients with controlled, asymptomatic arrhythmias were allowed1

Patients received CALQUENCE 100 mg orally approximately every 12 hours until disease progression or unacceptable toxicity for either CALQUENCE + obinutuzumab or CALQUENCE monotherapy.2

Interim analysis had a median follow-up of 28.3 months (range: 0.0-40.8 months).1,2

Long-term analysis had a median follow-up of 74.5 months (range: 0.0-89.0 months).3

*For CALQUENCE + obinutuzumab, obinutuzumab was given 28 days after the first dose of CALQUENCE (Cycle 2, Day 1), and was given for up to 6 cycles. Refer to the obinutuzumab Prescribing Information for recommended obinutuzumab dosing information.2

The primary endpoint at the interim analysis was IRC-assessed PFS (CALQUENCE + obinutuzumab vs GClb). After the interim analysis at 28.3 months, PFS was INV-assessed only.2,3

Select secondary endpoints at interim analysis were IRC-assessed PFS (CALQUENCE monotherapy vs GClb), IRC-assessed ORR, OS, and safety. After the interim analysis at 28.3 months, PFS and ORR were INV-assessed only.1,3

§Equivalent vitamin K antagonists were not allowed.2

BTKi=Bruton tyrosine kinase inhibitor; CIRS-G=Cumulative Illness Rating Scale–Geriatric; CLL=chronic lymphocytic leukemia; CrCl=creatinine clearance; INV=investigator; IRC=Independent Review Committee; ORR=overall response rate; OS=overall survival; PFS=progression-free survival.
