Treatment for Non-Small Cell Lung Cancer

Clovis Oncology Submits NDA for Rociletinib for the Treatment of Advanced EGFR-Mutant T790M+ Non-small Cell Lung Cancer

BOULDER, Colo.--(BUSINESS WIRE)--Aug. 3, 2015-- Clovis Oncology, Inc. (NASDAQ: CLVS) announced today that it has submitted its New Drug Application (NDA) regulatory filing to the U.S. Food and Drug Administration (FDA) 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 and have the EGFR T790M mutation as detected by an FDA approved test. 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. Rociletinib was granted Breakthrough Therapy designation by the U.S. FDA in May 2014.

“The submissions of our first NDA and MAA for rociletinib represent a major step forward for our company,” said Patrick J. Mahaffy, President and CEO of Clovis Oncology. “These two submissions – completed on the same day, no less -- were made possible through the tremendous commitment and hard work of Clovis employees and our clinical collaborators at leading U.S. and international academic institutions over the last many months, and I am grateful for their tireless efforts. We are actively preparing for what we hope to be our first U.S. commercial launch, and the opportunity to address the needs of patients with T790M-positive EGFR-mutant non-small cell lung cancer. We are also actively building our commercial organization in Europe to prepare for a potential launch next year.”

QIAGEN, Clovis’ companion diagnostic partner, intends to file a supplemental PMA application of its approved therascreen EGFR test with the FDA to allow for regulatory approval of the companion diagnostic concurrent with rociletinib approval. Analytical performance of the therascreen EGFR test has been established for 21 EGFR mutations, including the most prevalent resistance mutation, T790M. The test supports efficient laboratory workflow with real-time PCR technology on the FDA approved Rotor-Gene Q MDx, which is part of QIAGEN’s QIAsymphony family of laboratory solutions.

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. Rociletinib was granted Breakthrough Therapy designation by the U.S. FDA in May 2014.

About Rociletinib Clinical Development

Clovis has several studies underway in EGFR-mutant NSCLC:

  • 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 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 of PD-L1, 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.
