Loxo Oncology Announces Completion of Clinical Trial Enrollment for Larotrectinib NDA Primary Efficacy Analysis

STAMFORD, Conn., Feb. 21, 2017 (GLOBE NEWSWIRE) -- Loxo Oncology, Inc. (Nasdaq:LOXO), a biopharmaceutical company innovating the development of highly selective medicines for patients with genetically defined cancers, today announced that the company has completed clinical trial enrollment for the larotrectinib New Drug Application (NDA) primary efficacy analysis. This determination is based on written feedback from the U.S. Food and Drug Administration (FDA), which affirmed the target enrollment goal for the primary efficacy analysis data set to support an NDA filing.

All larotrectinib clinical trials will remain open to provide a mechanism for drug access to newly identified patients during forthcoming regulatory interactions and review. 

The primary efficacy analysis for larotrectinib will be based on RECIST v1.1 overall response rate (ORR), as determined by independent radiology review, for NTRK fusion patients enrolled across the three ongoing larotrectinib clinical studies. Durability of response and safety are also critical elements of the regulatory risk-benefit determination. The company expects to report top-line data for the NDA dataset in the second half of 2017, and expects to submit a New Drug Application in late 2017 or early 2018, and a European Marketing Authorisation Application (MAA) in 2018.

Loxo Oncology intends to submit for approval for the same indication statement upon which the FDA granted Breakthrough Therapy Designation for larotrectinib, “for the treatment of unresectable or metastatic solid tumors with NTRK-fusion proteins in adult and pediatric patients who require systemic therapy and who have either progressed following prior treatment or who have no acceptable alternative treatments.”

About Larotrectinib (LOXO-101)
Larotrectinib (LOXO-101) is a potent, oral and selective investigational new drug in clinical development for the treatment of patients with cancers that harbor abnormalities involving the tropomyosin receptor kinases (TRKs). Growing research suggests that the NTRK genes, which encode for TRKs, can become abnormally fused to other genes, resulting in growth signals that can lead to cancer in many sites of the body. In an ongoing Phase 1 clinical trial, larotrectinib has demonstrated encouraging preliminary efficacy. Larotrectinib is also being evaluated in the NAVIGATE global Phase 2 multi-center basket trial in patients with solid tumors that harbor TRK gene fusions, and the SCOUT Phase 1/2 trial in pediatric patients, including patients with advanced cancer, TRK gene fusions and infantile fibrosarcoma. Larotrectinib has been granted Breakthrough Therapy Designation and Rare Pediatric Disease Designation by the U.S. FDA. For additional information about the larotrectinib clinical trials, please refer to www.clinicaltrials.gov.
