Clovis Oncology Enters into Clinical Trial Collaboration

August 11, 2015

Study to evaluate the combination of rociletinib (CO-1686) with Genentech’s atezolizumab (MPDL3280A) for patients with advanced EGFR-mutant non-small cell lung cancer

BOULDER, Colo.--(BUSINESS WIRE)--Aug. 11, 2015-- Clovis Oncology, Inc. (NASDAQ: CLVS) announced today that they have entered into a clinical trial collaboration with Genentech, a member of the Roche Group to evaluate a novel combination therapy of Genentech’s investigational cancer immunotherapy atezolizumab (MPDL3280A; anti-PDL1) and rociletinib for the treatment of advanced EGFR-mutant non-small cell lung cancer (NSCLC). Rociletinib is the Company’s novel, oral targeted covalent (irreversible) mutant-selective inhibitor of EGFR in development for the treatment of NSCLC in patients with initial activating EGFR mutations, as well as the dominant resistance mutation T790M.

The Phase 1b/2 trial of rociletinib in combination with atezolizumab is planned to begin enrolling patients before the end of 2015. The trial, which is sponsored by Clovis, is designed to assess the safety and activity of the combination in patients with activating EGFR mutation-positive (EGFRm) advanced or metastatic NSCLC. The Phase 1b portion of the trial will evaluate the safety, tolerability and pharmacokinetics of the combination in this population. The Phase 2 portion of the trial will evaluate the activity of the combination in two subgroups of patients with EGFR-mutant advanced or metastatic NSCLC: those who have not previously received an EGFR TKI or chemotherapy, and those who have progressed on a prior EGFR TKI. T790M-negative and T790M-positive patients will be enrolled in the Phase 1b portion of the trial and in the Phase 2 portion of the trial in the subgroup of patients who have progressed on a prior EGFR TKI. While patients’ tumors are not required to express PD-L1 to enroll in the study, PD-L1 expression will be assessed in archival and/or fresh tissue as part of the study.

“We are delighted to evaluate atezolizumab with rociletinib to explore whether the combination can add to the clinical benefit in patients with mutant EGFR non-small cell lung cancer,” said Patrick J. Mahaffy, President and CEO of Clovis Oncology. “In particular, we are very enthusiastic to explore the potential of this combination in both newly-diagnosed patients as well as those previously treated with TKI therapy.”

Rociletinib was granted Breakthrough Therapy designation by the FDA in May 2014. Clovis announced on August 3 that it submitted its New Drug Application (NDA) regulatory filing to the U.S. Food and Drug Administration (FDA) and submitted its Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) through the centralized procedure for rociletinib for the treatment of patients with mutant epidermal growth factor receptor (EGFR) non-small cell lung cancer (NSCLC) who have been previously treated with an EGFR-targeted therapy.

About Rociletinib

Rociletinib is an oral, potent, mutant-selective inhibitor of epidermal growth factor receptor (EGFR) under investigation for the treatment of EGFR-mutated non-small cell lung cancer (NSCLC). Rociletinib targets the activating mutations of EGFR (L858R and Del19), while also inhibiting the dominant acquired resistance mutation, T790M, which develops in approximately 60 percent of patients treated with first- and second-generation EGFR inhibitors, while sparing wild-type, or “normal” EGFR at anticipated therapeutic doses. Accordingly, it has the potential to treat NSCLC patients with EGFR mutations both as a first-line or second-line treatment with a potentially reduced toxicity profile.

About Rociletinib Clinical Development

Clovis has several studies in EGFR-mutant NSCLC underway:

  • TIGER-X is a Phase 1/2 study designed to evaluate the safety and efficacy of three different doses of rociletinib in a very advanced patient population.
  • TIGER-1 is a randomized Phase 2/3 registration study versus erlotinib in newly-diagnosed patients.
  • TIGER-2 is a global registration study underway in both T790M-positive and T790M-negative patients directly after progression on their first and only TKI therapy.
  • TIGER-3 is a randomized, comparative study versus chemotherapy in both T790M-positive and T790M-negative patients with acquired TKI resistance.
  • A Phase 1 study of rociletinib in Japan has completed enrollment and a Phase 2 study in Japanese patients, agreed upon with Japanese regulatory authorities, is expected to initiate in the second half of 2015.
  • Multiple combination studies are planned to initiate in the second half of 2015, including inhibitors PD-1 and MEK.

About Lung Cancer and EGFR Mutations

Lung cancer is the most common cancer worldwide with 1.35 million new cases annually, with NSCLC accounting for almost 85 percent of all lung cancers. NSCLC progresses rapidly with a five-year survival rate in advanced NSCLC patients of less than five percent. EGFR activating mutations occur in approximately 10 to 15 percent of NSCLC cases in Caucasian patients and approximately 30 to 35 percent in East Asian patients. These patients often experience significant tumor response to erlotinib, afatinib and gefitinib, which are first- and second-generation EGFR inhibitors. However, most patients ultimately progress on these therapies, with approximately 60 percent of patients developing acquired resistance from a second, “gatekeeper” mutation, T790M. Currently, no targeted therapies are approved for treatment of this mutation.
