Tumor-agnostic data supporting approval demonstrated an overall response rate (ORR) of 44% across multiple tumor types
FDA simultaneously grants traditional approval in adults with locally advanced or metastatic non-small cell lung cancer (NSCLC) with a RET gene fusion, as detected by an FDA-approved test
INDIANAPOLIS, Sept. 21, 2022 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY) today announced the U.S. Food and Drug Administration (FDA) has granted approval to Retevmo® (selpercatinib, 40 mg & 80 mg capsules) for adult patients with locally advanced or metastatic solid tumors with a rearranged during transfection (RET) gene fusion that have progressed on or following prior systemic treatment or who have no satisfactory alternative treatment options. This indication is approved under accelerated approval based on ORR and duration of response (DOR). Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trial.
"In the LIBRETTO-001 trial, selpercatinib demonstrated clinically meaningful and durable responses across a variety of tumor types in patients with RET-driven cancers, including pancreatic, colon and other cancers in need of new treatment options," said Vivek Subbiah, M.D., associate professor of Investigational Cancer Therapeutics at The University of Texas MD Anderson Cancer Center and co-investigator for LIBRETTO-001. "These data and FDA approval of the tumor-agnostic indication underscore the importance of routine, comprehensive genomic testing for patients across a wide variety of tumor types."
In addition to the tumor-agnostic approval, the FDA has granted traditional approval for Retevmo in adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with a RET gene fusion, as detected by an FDA-approved test. This FDA action broadens the Retevmo label to include patients with locally advanced disease and converts the May 2020 accelerated approval for NSCLC to a traditional approval.
The labeling for Retevmo contains warnings and precautions for hepatotoxicity (evidence of liver dysfunction), interstitial lung disease (ILD)/pneumonitis, hypertension, QT interval prolongation, hemorrhagic events, hypersensitivity, tumor lysis syndrome, risk of impaired wound healing, hypothyroidism, and embryo-fetal toxicity.
"Since its initial accelerated approval, Retevmo has shifted the treatment paradigm for patients with RET-altered cancers," said David Hyman, M.D., chief medical officer, Loxo@Lilly. "Retevmo is the first and only RET inhibitor to receive both tumor-agnostic accelerated approval and traditional approval in NSCLC, further supporting its ability to deliver meaningful clinical benefit for patients across diverse tumor types."

The two approvals are supported by data from the pivotal LIBRETTO-001 trial, which is the largest clinical trial of patients with RET-driven cancers treated with a RET inhibitor. The multicenter, open-label, multi-cohort study enrolled patients with locally advanced or metastatic RET-driven solid tumors, including NSCLC. Major efficacy outcomes were ORR and DOR, assessed by a blinded independent review committee (BIRC). Prespecified secondary endpoints included central nervous system (CNS) ORR and CNS DOR.
RET Fusion-Positive Solid Tumors
Among the 41 patients in the tumor-agnostic data set, the most common cancers were pancreatic adenocarcinoma (27%), colorectal (24%), salivary (10%), and unknown primary (7%). Thirty-seven patients (90%) received prior systemic therapy (median 2 [range 0 – 9]; 32% received 3 or more). Efficacy results are summarized below:
