Lilly updates Phase 1/2 lung cancer data

 Eli Lilly and Company (NYSE: LLY) today announced updated data from the Phase 1/2 LIBRETTO-001 trial of Retevmo® (selpercatinib 40 mg & 80 mg capsules) in patients with RET fusion-positive non-small cell lung cancer (NSCLC). Retevmo (marketed as Retsevmo® outside of the U.S.) is a selective and potent RET kinase inhibitor that is approved in multiple countries including the United States for treatment of adult patients with metastatic rearranged during transfection (RET) fusion-positive NSCLC, and the treatment of adult and pediatric patients 12 years of age and older with advanced or metastatic RET-mutant medullary thyroid cancer (MTC) who require systemic therapy, or advanced or metastatic RET fusion-positive thyroid cancer who require systemic therapy and who are radioactive iodine-refractory (if radioactive iodine is appropriate). These data were presented at the European Lung Cancer (ELCC) 2022 (poster 27p).

"The LIBRETTO trial provides the largest set of clinical data for a RET inhibitor and these results continue to demonstrate evidence of meaningful clinical outcomes for patients with metastatic RET fusion-positive NSCLC treated with Retevmo, including those with difficult-to-treat brain metastases," said David Hyman, M.D. chief medical officer, oncology at Lilly. "We are continuing to build on the robust body of evidence supporting Retevmo, including through an ongoing randomized Phase 3 confirmatory study, with a planned readout in 2023."

The updated analysis utilized a June 15, 2021, data cut-off and included 355 patients who were eligible for efficacy analysis, 247 of which were previously treated with at least one line of platinum chemotherapy and 69 of which were treatment-naïve. Patients who were previously treated with at least one line of platinum chemotherapy received a median of two prior treatment regimens (range: 1-15), with 58% having received anti-PD-1 or anti-PD-L1 therapy. Responses are based on independent review committee (IRC) assessment.
