LY-004 Efficacy
Accelerated approval of CALQUENCE for R/R MCL was based on overall response rate in the pivotal LY-004 study.
CALQUENCE: A BTKi for adult patients with MCL after at least one prior therapy1
Continued approval of this indication may be contingent upon verification and description of clinical benefit in confirmatory clinical trials.
Study design1
A Phase 2, open-label, single-arm, multicenter trial of CALQUENCE monotherapy in patients (≥18 years) with MCL who had received at least one prior therapy (N=124).1,2
Patients received CALQUENCE 100 mg approximately every 12 hours until disease progression or unacceptable toxicity.1
Investigator-assessed ORR was the primary endpoint; secondary endpoints included DoR, PFS, and OS. IRC-assessed ORR was a secondary endpoint.2
Data at initial analysis
- Efficacy and safety endpoints measured from March 12, 2015, to January 5, 2016; the median study follow-up time was 15.2 months2
- Independent Review Committee (IRC) and investigator assessments conducted on primary and secondary efficacy endpoints per 2014 Lugano Classification response criteria for NHL1,2
- Investigator-assessed ORR was the primary endpoint; secondary endpoints included DoR, PFS, and OS. IRC-assessed ORR was a secondary endpoint2
Long-term follow-up data
- Efficacy and safety endpoints from an additional year of follow-up representing a 38-month median follow-up3,4
- Investigator assessments were conducted on primary and secondary efficacy endpoints per 2014 Lugano Classification response criteria for NHL3
- IRC–endpoint analyses were not conducted in long-term data update2
INITIAL ANALYSIS (15.2-MONTH MEDIAN FOLLOW-UP)
LONG-TERM ANALYSIS (38-MONTH MEDIAN FOLLOW-UP)
Long-term follow-up

†CR is defined as the disappearance of evidence of disease, including extranodal disease (if present at baseline), and/or PET negativity based on FDG uptake less than or equal to the liver by PET-CT scan; PR is defined as a reduction of measurable or metabolic disease and no new lesions, as identified by PET-CT scan. Efficacy endpoints were assessed by the investigator and by an Independent Review Committee at initial analysis.1,7
‡One patient with an ECOG performance status of 1 at screening had an ECOG performance status of 3 at the baseline assessment (cycle 1, day 1).2
§The site of disease for 1 patient was changed from osseous/bone to none after the original cutoff date that was previously published.4
