Ignyta, Inc.,a biotechnology company focused on precision medicine in oncology, today announced that the U.S. Food and Drug Administration (FDA) has granted a Breakthrough Therapy Designation (BTD) to entrectinib “for the treatment of NTRK fusion-positive, locally advanced or metastatic solid tumors in adult and pediatric patients who have either progressed following prior therapies or who have no acceptable standard therapies.” Entrectinib is the company’s investigational, orally available, CNS-active tyrosine kinase inhibitor targeting tumors that harbor NTRK1/2/3, ROS1, or ALK gene fusions.
The FDA’s Breakthrough Therapy Designation is intended to expedite development and review timelines of potential new medicines for use in the treatment of a serious or life-threatening condition when preliminary clinical evidence indicates the drug may demonstrate substantial improvement over available therapies on one or more clinically significant endpoints.
Entrectinib is a novel, orally available, CNS-active tyrosine kinase inhibitor targeting tumors that harbor activating alterations to NTRK1/2/3 (encoding TRKA/TRKB/TRKC), ROS1 or ALK. Entrectinib is the only TRK inhibitor with clinically demonstrated activity against primary and metastatic CNS disease, and does not have undesirable off-target activity. This product candidate is in a Phase 2 clinical trial called STARTRK-2, which is the second of the “Studies of Tumor Alterations Responsive to Targeting Receptor Kinases.” The trial is a global, multicenter, open label, potentially registration-enabling Phase 2 clinical trial of entrectinib that utilizes a basket design with screening of patient tumor samples for the relevant targets. Such a basket design takes full advantage of entrectinib’s demonstrated preliminary clinical activity across a range of different tumor types and molecular targets.
About Ignyta, Inc.
Blazing a New Future for Patients with Cancer™
At Ignyta, we work tirelessly on behalf of patients with cancer to offer potentially life-saving, precisely targeted therapeutics (Rx) guided by companion diagnostic (Dx) tests. Our integrated Rx/Dx strategy allows us to enter uncharted territory, illuminating the molecular drivers of cancer and quickly advancing treatments to address them. This approach embraces even those patients with the rarest cancers, who have the highest unmet need and who may otherwise not have access to effective treatment options. With our pipeline of potentially first-in-class or best-in-class precision medicines, we are pursuing the ultimate goal of not just shrinking tumors, but eradicating cancer relapse and recurrence in precisely defined patient populations.
