Lilly's Retevmo® (selpercatinib) is the First Targeted Therapy to Demonstrate Superior Progression-Free Survival Compared to a PD-1 Inhibitor Plus Chemotherapy for Adults with Newly-Diagnosed Advanced or Metastatic RET Fusion-Positive Non-Small Cell Lung Cancer
- The LIBRETTO-431 study demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) for Retevmo, positioning it as a potential first-line treatment for patients with RET fusion-positive advanced or metastatic NSCLC.
- None.
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.
LIBRETTO-431 is a Phase 3, randomized, open-label trial evaluating Retevmo versus platinum-based chemotherapy (cisplatin or carboplatin) plus pemetrexed with or without pembrolizumab, which is a current first-line standard of care option for patients with EGFR/ALK-negative NSCLC. LIBRETTO-431 is the first randomized trial comparing the safety and effectiveness of a targeted therapy to a PD-1 inhibitor plus chemotherapy in a biomarker selected patient population.
"The LIBRETTO-431 trial aims to answer an important question about the selection of initial treatment for people with advanced RET fusion-positive NSCLC and these results suggest Retevmo should be considered a first-line standard of care," said David Hyman, M.D., chief medical officer, Loxo@Lilly. "Additionally, this clinically meaningful achievement of improved outcomes underscores the importance of timely and comprehensive genomic testing to inform initial treatment decisions for all patients with NSCLC. The results of this study provide further confirmation that RET status – like EGFR, ALK, and others in the family of lung cancer oncogenic drivers – should be known prior to initiating therapy. We look forward to sharing these data in more detail with the oncology community."
These results build on the data from LIBRETTO-001, the largest clinical trial of patients with RET-driven cancers treated with a RET inhibitor, which spans 16 countries and 85 sites, and includes a dose escalation phase (Phase 1) and a dose expansion phase (Phase 2). In this trial, Retevmo demonstrated clinically meaningful and durable responses across a variety of tumor types in patients with RET-driven cancers.
NSCLC accounts for about 85 percent of all lung cancer diagnoses in the
Full results from the LIBRETTO-431 trial will be presented at an upcoming medical meeting, submitted to a peer-reviewed journal, and discussed with health authorities.
About LIBRETTO-431
LIBRETTO-431 is a randomized Phase 3 clinical trial of patients with treatment-naïve RET fusion-positive NSCLC. The trial enrolled 261 patients with advanced or metastatic RET fusion-positive NSCLC who had received no prior systemic therapy for metastatic disease. Enrolled trial participants were randomized 2:1 to receive either selpercatinib or platinum-based (carboplatin or cisplatin) and pemetrexed therapy with or without pembrolizumab as initial treatment of their advanced or metastatic RET fusion-positive NSCLC. RET fusions may be identified using local testing. This trial's primary endpoint is progression-free survival (PFS) and secondary endpoints include overall survival (OS), overall response rate (ORR), duration of response (DoR), and intracranial ORR. For patients randomized to the control arm, crossover was allowed at progression.
About Retevmo® (selpercatinib, 40 mg & 80 mg capsules)
Retevmo (selpercatinib, formerly known as LOXO-292) (pronounced reh-TEHV-moh) is a highly selective and potent RET kinase inhibitor with central nervous system (CNS) activity. Retevmo may affect both tumor cells and healthy cells, which can result in side effects. RET-driver alterations are predominantly mutually exclusive from other oncogenic drivers. Retevmo is a
IMPORTANT SAFETY INFORMATION FOR RETEVMO® (selpercatinib)
Hepatotoxicity: Serious hepatic adverse reactions occurred in
Severe, life-threatening, and fatal interstitial lung disease (ILD)/pneumonitis can occur in patients treated with Retevmo. ILD/pneumonitis occurred in
Hypertension occurred in
Retevmo can cause concentration-dependent QT interval prolongation. An increase in QTcF interval to >500 ms was measured in
Serious, including fatal, hemorrhagic events can occur with Retevmo. Grade ≥3 hemorrhagic events occurred in
Hypersensitivity occurred in
Tumor lysis syndrome (TLS) occurred in
Impaired wound healing can occur in patients who receive drugs that inhibit the vascular endothelial growth factor (VEGF) signaling pathway. Therefore, Retevmo has the potential to adversely affect wound healing. Withhold Retevmo for at least 7 days prior to elective surgery. Do not administer for at least 2 weeks following major surgery and until adequate wound healing. The safety of resumption of Retevmo after resolution of wound healing complications has not been established.
Retevmo can cause hypothyroidism. Hypothyroidism occurred in
Based on data from animal reproduction studies and its mechanism of action, Retevmo can cause fetal harm when administered to a pregnant woman. Administration of selpercatinib to pregnant rats during organogenesis at maternal exposures that were approximately equal to those observed at the recommended human dose of 160 mg twice daily resulted in embryolethality and malformations. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential and males with female partners of reproductive potential to use effective contraception during treatment with Retevmo and for 1 week after the last dose. There are no data on the presence of selpercatinib or its metabolites in human milk or on their effects on the breastfed child or on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with Retevmo and for 1 week after the last dose.

Laboratory abnormalities (all grades ≥
Concomitant use of acid-reducing agents decreases selpercatinib plasma concentrations which may reduce Retevmo anti-tumor activity. Avoid concomitant use of proton-pump inhibitors (PPIs), histamine-2 (H2) receptor antagonists, and locally-acting antacids with Retevmo. If coadministration cannot be avoided, take Retevmo with food (with a PPI) or modify its administration time (with a H2 receptor antagonist or a locally-acting antacid).
Concomitant use of strong and moderate CYP3A inhibitors increases selpercatinib plasma concentrations which may increase the risk of Retevmo adverse reactions including QTc interval prolongation. Avoid concomitant use of strong and moderate CYP3A inhibitors with Retevmo. If concomitant use of a strong or moderate CYP3A inhibitor cannot be avoided, reduce the Retevmo dosage as recommended and monitor the QT interval with ECGs more frequently.
Concomitant use of strong and moderate CYP3A inducers decreases selpercatinib plasma concentrations which may reduce Retevmo anti-tumor activity. Avoid coadministration of Retevmo with strong and moderate CYP3A inducers.
Concomitant use of Retevmo with CYP2C8 and CYP3A substrates increases their plasma concentrations which may increase the risk of adverse reactions related to these substrates. Avoid coadministration of Retevmo with CYP2C8 and CYP3A substrates where minimal concentration changes may lead to increased adverse reactions. If coadministration cannot be avoided, follow recommendations for CYP2C8 and CYP3A substrates provided in their approved product labeling.
Retevmo is a P-glycoprotein (P-gp) inhibitor. Concomitant use of Retevmo with P-gp substrates increases their plasma concentrations, which may increase the risk of adverse reactions related to these substrates. Avoid coadministration of Retevmo with P-gp substrates where minimal concentration changes may lead to increased adverse reactions. If coadministration cannot be avoided, follow recommendations for P-gp substrates provided in their approved product labeling.
No dosage modification is recommended for patients with mild to severe renal impairment (estimated Glomerular Filtration Rate [eGFR] ≥15 to 89 mL/min, estimated by Modification of Diet in Renal Disease [MDRD] equation). A recommended dosage has not been established for patients with end-stage renal disease.
Reduce the dose when administering Retevmo to patients with severe hepatic impairment (total bilirubin greater than 3 to 10 times upper limit of normal [ULN] and any AST). No dosage modification is recommended for patients with mild or moderate hepatic impairment. Monitor for Retevmo-related adverse reactions in patients with hepatic impairment.
