Larotrectinib Sulfate

VITRAKVI ® is now fully approved for adult and pediatric patients with solid tumors that have a neurotrophic receptor tyrosine kinase ( NTRK) gene fusion without a known acquired resistance mutation that have spread or who aren’t eligible for surgery, and have no satisfactory alternative treatments or that have progressed following treatment, following accelerated approval previously granted in this indication The full approval of VITRAKVI is based on the results of confirmatory trials that support VITRAKVI as a potential new standard of care treatment option for NTRK gene fusion-positive tumors in adult and pediatric patients VITRAKVI is a first-in-class treatment exclusively designed to inhibit TRK WHIPPANY, N.J.--(BUSINESS WIRE)--Bayer today announced that the U.S. Food and Drug Administration (FDA) has granted full approval for VITRAKVI® (larotrectinib), a first-in-class TRK inhibitor for the treatment of adult and pediatric patients with solid tumors that have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion without a known acquired resistance mutation, are metastatic or where surgical resection is likely to result in severe morbidity, and have no satisfactory alternative treatments or that have progressed following treatment.1 VITRAKVI has demonstrated clinically meaningful and durable responses across a range of NTRK fusion-positive solid tumors. VITRAKVI was first granted accelerated approval by FDA in November 2018.1 “This first full approval of an NTRK inhibitor by the FDA represents the culmination of research and dedication by the Bayer team,” said Chandra Goda, Executive Director, U.S. VITRAKVI Brand Lead. “We are proud to deliver on our promise for patients with this significant step forward, providing a treatment option for pediatric and adult patients living with NTRK gene fusion-positive cancers. This milestone reinforces Bayer's commitment to delivering innovative solutions that address the unique needs of patients and their families." "The full approval of VITRAKVI by the FDA is a welcome step forward, solidifying its place as a treatment option for patients with NTRK gene fusion-positive cancers," said Andrea Ferris, President and CEO, LUNGevity Foundation. "This milestone not only benefits patients today but also paves the way for further advancements in NTRK gene therapies in the future." This approval is based on data from three multicenter, open-label, single-arm clinical trials: LOXO-TRK-14001 (NCT02122913), SCOUT (NCT02637687), and NAVIGATE (NCT02576431). This analysis included pediatric and adult patients with unresectable or metastatic solid tumors with an NTRK gene fusion (n=339). All patients were required to have progressed following systemic therapy for their disease, if available, or would have required surgery with significant morbidity for locally advanced disease.1 The major efficacy outcome measures were overall response rate (ORR) and duration of response (DOR), as determined by a blinded independent review committee (BIRC) according to RECIST v1.1. 1 Safety was assessed in 444 patients across the three trials.1 Pooled efficacy results showed an ORR of 60% (95% CI: 55%-65%) with a complete response (CR) rate of 24% and a partial response (PR) rate of 36%.1 Five percent of patients with complete response were pathological complete response. Patients undergoing a surgical resection whose post-operative pathologic assessment showed no viable tumor cells and negative margins were pathological complete responders provided that no other sites of disease were present. Median DOR was 43.3 months (95% CI: 32.5-NE (not evaluable)).1 The most common (≥20%) adverse reactions, including laboratory abnormalities, with VITRAKVI were increased AST, increased ALT, anemia, hypoalbuminemia, musculoskeletal pain, increased alkaline phosphatase, leukopenia, lymphopenia, neutropenia, hypocalcemia, fatigue, vomiting, cough, constipation, pyrexia, diarrhea, nausea, abdominal pain, dizziness, and rash.1 Serious adverse events (AEs) reported included central nervous system (CNS) problems, bone fractures and liver problems.1 About VITRAKVI® (larotrectinib) VITRAKVI, a first-in-class oral TRK inhibitor, was exclusively designed to inhibit against the TRK family of proteins (TRKA, TRKB, and TRKC). In in vitro and in vivo tumor models, VITRAKVI demonstrated anti-tumor activity in cells with constitutive activation of TRK proteins resulting from gene fusions, deletion of a protein regulatory domain, or in cells with TRK protein overexpression. Constitutively-activated chimeric TRK fusion proteins can act as an oncogenic driver, promoting cell proliferation and survival in tumor cell lines.1 In the U.S., VITRAKVI is approved for the treatment of adult and pediatric patients with solid tumors that display a neurotrophic receptor tyrosine kinase (NTRK) gene fusion.1 Following the acquisition of Loxo Oncology by Eli Lilly and Company in February 2019, Bayer has obtained the exclusive licensing rights for the global development and commercialization, including in the U.S., for VITRAKVI. INDICATION VITRAKVI is indicated for the treatment of adult and pediatric patients with solid tumors that: have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion without a known acquired resistance mutation, are metastatic or where surgical resection is likely to result in severe morbidity, and have no satisfactory alternative treatments or that have progressed following treatment. Select patients for therapy based on an FDA-approved test. IMPORTANT SAFETY INFORMATION Warnings and Precautions Central Nervous System Effects: Central nervous system (CNS) adverse reactions occurred in patients receiving VITRAKVI, including dizziness, cognitive impairment, mood disorders, and sleep disturbances.

If withheld, modify the VITRAKVI dosage when resumed. Skeletal Fractures: Skeletal fractures can occur in patients taking VITRAKVI. Among 444 patients who received VITRAKVI across clinical trials, fractures occurred in 7% of patients; 6% of 290 adult patients and 10% of 154 pediatric patients. Median time to first fracture was 13 months (range 27 days to 73 months) in patients followed per fracture. The most common fractures were of the rib (1.4%), fibula, foot or wrist (0.7% each). Most fractures were associated with minimal or moderate trauma. Some fractures were associated with radiologic abnormalities suggestive of local tumor involvement. VITRAKVI treatment was interrupted due to fracture in 1.4% patients. Promptly evaluate patients with signs or symptoms of potential fracture (e.g., pain, changes in mobility, deformity). There are no data on the effects of VITRAKVI on healing of known fractures or risk of future fractures. Hepatotoxicity: Hepatotoxicity including drug induced liver injury (DILI) has occurred in patients taking VITRAKVI. In patients who received VITRAKVI (n=444), increased AST of any grade occurred in 62% of patients and increased ALT of any grade occurred in 61%. Grade 3-4 increased AST or ALT occurred in 7% and 8% of patients, respectively. The median time to onset of increased AST was 1.9 months (range: 4 days to 3.8 years). The median time to onset of increased ALT was 1.9 months (range: 1 day to 4.9 years). Increased AST and ALT leading to dose modifications occurred in 1.6% and 3.2% of patients, respectively. Increased AST or ALT led to permanent discontinuation in 4 (0.9%) patients. There have been reports from clinical studies and postmarketing cases of Grade ≥ 2 increases in ALT and/or AST with increases in bilirubin ≥ 2 x ULN. Obtain liver function tests (ALT, AST, ALP and bilirubin) before initiation of VITRAKVI and monitor every 2 weeks during the first 2 months of treatment, then monthly thereafter, or more frequently following the occurrence of Grade 2 or greater AST or ALT elevation. Temporarily withhold, reduce the dose, or permanently discontinue VITRAKVI based on severity. Embryo-Fetal Toxicity: VITRAKVI can cause fetal harm when administered to a pregnant woman. Larotrectinib resulted in malformations in rats and rabbits at maternal exposures that were approximately 11- and 0.7-times, respectively, those observed at the clinical dose of 100 mg twice daily.

About TRK Fusion Cancer2 TRK fusion cancer occurs when an NTRK gene fuses with another unrelated gene, producing an altered TRK protein. The altered protein, or TRK fusion protein, becomes constitutively active or overexpressed, triggering a signaling cascade. These TRK fusion proteins act as oncogenic drivers promoting cell growth and survival, leading to TRK fusion cancer, regardless of where it originates in the body. TRK fusion cancer is not limited to certain types of tissues and can occur in any part of the body. TRK fusion is present in many tumors with varying frequency, including lung, thyroid, gastrointestinal cancers (colon, cholangiocarcinoma, pancreatic and appendiceal), sarcoma, CNS cancers (glioma and glioblastoma), salivary gland cancers (mammary analogue secretory carcinoma) and pediatric cancers (infantile fibrosarcoma and soft tissue sarcoma).2 TRK fusion cancer is diagnosed through the identification of NTRK gene fusions using specific tests, including those that employ next-generation sequencing (NGS) and fluorescence in situ hybridization (FISH).2 About Oncology at Bayer Bayer is committed to delivering science for a better life by advancing a portfolio of innovative treatments.

A 295,000+ patient study revealed variable efficacy among cancers for patients treated with tissue-agnostic drugs and uncovered the potential for expanding approvals to other drugs of the same class IRVING, Texas, March 20, 2025 /PRNewswire/ -- Caris Life Sciences® (Caris), a leading next-generation AI TechBio company and precision medicine pioneer, today announced the publication of "Real-world evidence provides clinical insights into tissue-agnostic therapeutic approvals" in Nature Communications. Utilizing the largest real-world clinical and genomic dataset of tissue-agnostic indications reported to date across more than 295,000 patients, the study provides a comprehensive evaluation of real-world outcomes for patients eligible for these powerful "pan-cancer" therapies, such as pembrolizumab and larotrectinib. These drugs are categorized as tumor-agnostic therapies, targeting specific genetic or molecular features of tumors rather than their anatomical location or histology. The study focused on the use and clinical benefits of tissue-agnostic therapies, which target specific molecular biomarkers across numerous cancer types. Key findings include: More than 20 percent of patients are candidates for a tissue-agnostic drug. Approximately five percent of patients who lacked any tumor-specific indication were found to carry a tissue-agnostic indication and became eligible for tissue-agnostic drug treatment. Tissue-agnostic therapy uptake was poor for rare indications, illustrating the need for enhanced clinical education. Current tissue-agnostic indications could potentially be expanded, as evidenced by clinical benefits in tumor types and drugs of the same class that were not investigated in the original clinical trials. "By harnessing the power of Caris' large clinico-genomic dataset, we have shown that tissue-agnostic drugs produce different outcomes in different tissues," said George W. Sledge, Jr., MD, EVP and Chief Medical Officer of Caris and study author. "We additionally found evidence of clinical benefit beyond approved indications, illustrating the enormous potential of real-world data to inform the clinical use of tissue-agnostic drug approvals, potentially improving patient outcomes." "Caris has generated one of the most extensive clinico-genomic datasets in oncology through years of comprehensive molecular profiling," said Caris President and study author David Spetzler, MS, PhD, MBA. "Our advanced analyses of real-world data now enable us to uncover findings of clinical value for large patient populations. One in five patients in our study were eligible for a tissue-agnostic drug, which demonstrates the widespread impact of our findings." Detailed Scientific Information This study used a real-world database of 295,316 molecularly profiled tumor samples with associated clinical outcomes data across 57 tumor types to investigate the utility and uptake of six tissue-agnostic therapies (pembrolizumab, larotrectinib, entrectinib, dostarlimab, dabrafenib and selpercatinib). At least one current FDA-approved tissue-agnostic indication (TMB-High, MSI-High/dMMR, BRAFV600E mutations, and NTRK and RET fusions) was detected in 21.5% of patients, including 5.4% lacking any tumor-specific indication. In patients with rare NTRK fusions, there was poor clinical uptake of the clinically successful targeted therapies larotrectinib and entrectinib, underlining the need for oncologist education on rare indications. Strikingly, significant differences in pembrolizumab-associated outcomes were observed across tumor types for the most common indications (TMB-High and MSI-High/dMMR), demonstrating that the effects of these therapies are not tissue-agnostic. Clinical benefits were also observed in tumor types and drugs of the same class (such as nivolumab) that were not investigated in pivotal clinical trials. This suggests the possible expansion of therapeutic avenues for a given tissue-agnostic indication. These findings demonstrate the power of Caris' extensive real-world dataset for generating valuable clinical insights to inform the clinical implementations of tissue-agnostic drug approvals and improve outcomes for patients with cancer.
