What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests how well the drug larotrectinib treats various solid cancers with specific genetic changes in the NTRK genes. Larotrectinib aims to block these gene changes to halt cancer growth. It suits individuals with solid tumor cancer that has spread and not responded to standard treatments. Participants should have these specific gene changes in their cancer and have exhausted typical treatment options without success. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial does not specify if you must stop taking your current medications, but you cannot take strong CYP3A4 inhibitors or inducers. If you are on such medications, you may need to stop them before starting the trial.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that larotrectinib is generally safe for individuals with TRK fusion-positive solid tumors. Most experience only mild side effects, such as tiredness, dizziness, and nausea, while serious side effects remain rare.

One study found that larotrectinib is safe for individuals with various tumors linked to NTRK gene fusions. The FDA has approved this treatment for other conditions, which supports its safety in humans.

Although this trial is in an early stage, current evidence suggests that larotrectinib is a promising and manageable option for many patients. It is important to discuss with a doctor what joining a trial could mean. ^{1 2 3 4 5}

Why are researchers excited about this study treatment for cancer?

Larotrectinib is unique because it specifically targets NTRK gene fusions, which are abnormal connections between genes that can drive cancer growth. Most cancer treatments, like chemotherapy or radiation, attack rapidly dividing cells in general, but larotrectinib zeroes in on these specific genetic abnormalities. This precision allows it to potentially be more effective and cause fewer side effects compared to standard treatments. Researchers are excited because this targeted approach could provide new hope for patients with various solid tumors that have NTRK fusions, offering a more personalized and potentially more effective treatment option.

What evidence suggests that this trial's treatments could be effective for solid cancers?

Research has shown that larotrectinib effectively treats cancers with NTRK gene fusions. Studies have demonstrated that larotrectinib produces strong and lasting effects against tumors in patients of all ages and cancer types. The drug blocks the activity of NTRK genes, which often promote cancer growth. Many patients with TRK fusion–positive cancers experienced significant tumor shrinkage. The U.S. FDA fully approved larotrectinib due to its proven tumor-fighting ability. Overall, this treatment has shown promising results in targeting specific genetic changes in cancer cells. Participants in this trial will receive larotrectinib to evaluate its effectiveness across various solid tumor types with NTRK fusions. ^{1 3 6 7 8}

Are You a Good Fit for This Trial?

This trial is for adults and children with solid tumors that have a specific gene change (NTRK1, NTRK2 or NTRK3). Participants must have tried standard treatments without success or be unlikely to benefit from them. They need at least one measurable tumor lesion, stable organ function, and no uncontrolled illnesses. People with certain infections or recent heart issues can't join.

Inclusion Criteria

Exclusion Criteria

Known or suspected hypersensitivity to the active substance or any IMP ingredients

I haven't taken any cancer drugs or been in a trial for 2 weeks.

My cancer progressed despite TRK inhibitor treatment.

Published Research Related to This Trial

Elacridar significantly increases the oral availability and brain penetration of larotrectinib, suggesting it could enhance the drug's therapeutic effects in treating NTRK fusion-positive cancers.

Both rifampin and ritonavir also improve the systemic exposure of larotrectinib, indicating that these drugs can be used to optimize larotrectinib's effectiveness by inhibiting specific transporters and enzymes involved in its metabolism.

Larotrectinib shows promising efficacy for treating solid tumors with NTRK gene fusions, with a 12-month progression-free survival (PFS) rate of 66.6% consistent between 2018 predictions and 2020 observed data from 102 patients across 15 tumor types.

While long-term PFS predictions varied due to differences in tumor responses, the overall survival (OS) predictions were reliable, with a 48-month OS rate of 67.2% aligning closely with observed data, indicating larotrectinib's potential for sustained effectiveness.

Estimating Long-Term Survival Outcomes for Tumor-Agnostic Therapies: Larotrectinib Case Study. Briggs, A., Paracha, N., Rosettie, K., et al.[2022]

Larotrectinib (VITRAKVI®) is a targeted therapy specifically designed to inhibit tropomyosin receptor kinases (TRK) in patients with cancers that have neurotrophic receptor tyrosine kinase (NTRK) gene fusions, making it a promising option for both adults and children.

Approved in November 2018 in the USA, larotrectinib is indicated for metastatic solid tumors with NTRK gene fusions when no other satisfactory treatments are available, highlighting its role as a critical option for patients with limited alternatives.

Larotrectinib: First Global Approval. Scott, LJ.[2020]

Larotrectinib is a small-molecule kinase inhibitor specifically designed to target NTRK fusions found in various cancers, showcasing its potential effectiveness across multiple tumor types.

It is the first treatment to receive FDA approval as 'tumor-agnostic,' meaning its use is based on specific genetic markers rather than the location of the cancer, highlighting a significant advancement in personalized medicine.

A Tumor-Agnostic NTRK (TRK) Inhibitor. Huang, FW., Feng, FY.[2020]

Larotrectinib, an FDA-approved treatment for certain cancers, is significantly affected by transporters like ABCB1 and ABCG2, which limit its oral availability and ability to penetrate the brain and testis, potentially impacting its therapeutic effectiveness.

The study found that the uptake transporter OATP1A/1B and the enzyme CYP3A also restrict larotrectinib's systemic exposure and oral availability, suggesting that understanding these mechanisms could enhance its clinical use.

Larotrectinib (VITRAKVI) is a highly effective treatment for patients with Trk fusion-positive cancers, showing a remarkable response rate of 75% regardless of cancer type, age, or gender.

The study developed a new LC-MS/MS method for accurately measuring Larotrectinib levels and assessing its metabolic stability, revealing a moderate extraction ratio and a half-life of approximately 48.8 minutes in human liver microsomes.
