Exelixis Provides Update on IMblaze370 Phase 3 Pivotal Trial of Atezolizumab and Cobimetinib in Patients With Heavily Pretreated Locally Advanced or Metastatic Colorectal Cancer
– Study did not meet its primary endpoint of improving overall survival versus regorafenib –
– Results will be submitted for presentation at an upcoming medical meeting –
The safety profile for the combination appeared consistent with the known safety profile of each individual medicine, and no new safety signals were identified with the combination. Genentech will further examine results from IMblaze370 and plans to present the data at an upcoming medical meeting.
“We are disappointed that the IMblaze370 trial did not reach a positive
conclusion,” said
Other ongoing late-stage clinical trials of cobimetinib include: IMspire150 TRILOGY, a fully enrolled study of cobimetinib, vemurafenib, and atezolizumab in previously untreated patients with BRAF V600-positive metastatic melanoma; and IMspire170, which is evaluating cobimetinib and atezolizumab in BRAF V600-wild type metastatic melanoma.
About the IMblaze370 Phase 3 Pivotal Trial
In early
Patients in the combination arm received cobimetinib on days 1 to 21 plus atezolizumab on day 1 and day 15 in a 28-day cycle. Patients in the experimental monotherapy arm received atezolizumab on day 1 of each 21-day cycle. Patients in the control arm received regorafenib on days 1 to 21 in a 28-day cycle. All patients continued to receive study drug until clinical benefit was no longer observed.
The primary endpoint of IMblaze370 is OS; key secondary endpoints include progression-free survival, objective response rate, and duration of response. IMblaze370 completed enrollment in the first quarter of 2017. More information about IMblaze370 is available at www.clinicaltrials.gov.
