VITRAKVI 25mg hard capsules are an essential treatment option for patients diagnosed with specific solid tumors that demonstrate NTRK gene fusion. This medication, containing larotrectinib sulfate, is designed for both adults and children, offering a targeted approach to cancer therapy.
Understanding the characteristics, indications, and guidelines associated with VITRAKVI is crucial for healthcare providers and patients alike. This article aims to provide comprehensive insights into the VITRAKVI 25mg hard capsules – Summary of Product Characteristics.
What is VITRAKVI 25mg hard capsules?
VITRAKVI 25mg hard capsules are a prescription medication primarily indicated for treating solid tumors featuring NTRK gene fusion. Larotrectinib, the active ingredient, works by inhibiting the activity of proteins produced by the NTRK gene, effectively blocking signals that promote tumor growth.
This treatment option is characterized by its ability to target tumors harboring NTRK fusions, providing a precision medicine approach that is often more effective than traditional chemotherapy. With both adult and pediatric formulations, VITRAKVI is a versatile medication in oncology.
VITRAKVI’s mechanism of action makes it a critical choice for patients with advanced solid tumors, enabling them to manage their condition more effectively.
What are the indications for VITRAKVI 25mg hard capsules?
The primary indications for VITRAKVI 25mg hard capsules revolve around the treatment of solid tumors that contain NTRK gene fusions. This includes a variety of cancer types, such as:
- Soft tissue sarcoma
- Thyroid cancer
- Non-small cell lung cancer
- Neuroblastoma
Healthcare providers are encouraged to perform genetic testing to confirm the presence of NTRK fusions before initiating treatment with VITRAKVI. Its use is particularly advantageous for patients who have received prior therapies without success.
The recommended treatment regimen for VITRAKVI reflects its targeted nature, allowing for effective management of tumors with minimal systemic toxicity.
What are the dosage guidelines for VITRAKVI 25mg hard capsules?
Dosage guidelines for VITRAKVI 25mg hard capsules are established to ensure optimal therapeutic outcomes while minimizing potential adverse effects. The general dosage recommendations are as follows:
- Adults: 100 mg taken orally twice daily.
- Pediatric patients: Dosage is determined based on body surface area, with a maximum dose of 100 mg per administration.
It is important to note that missed doses should not be compensated by taking double doses. Instead, patients should resume their regular dosing schedule as soon as possible. Adjustments to the dosage may be necessary in cases of adverse reactions or severe side effects.
Healthcare providers must monitor patients closely and consider the patient’s overall health condition when determining the appropriate dosage.
What are the common side effects of VITRAKVI 25mg hard capsules?
As with any medication, VITRAKVI 25mg hard capsules may cause side effects. The most common adverse reactions reported among patients include:
- Increased liver enzymes
- Anemia
- Muskuloskeletal pain
- Fatigue
- Gastrointestinal symptoms
Research indicates that approximately 53% of patients experience grade 3 or 4 reactions, illustrating the need for vigilant monitoring during treatment. Serious adverse events such as pneumonia and pyrexia have also been reported, which may necessitate treatment interruptions.
Patients are advised to report any unusual side effects to their healthcare provider immediately for appropriate management.
What should be considered for special populations when using VITRAKVI?
When prescribing VITRAKVI 25mg hard capsules, special considerations must be taken into account for certain populations, including the elderly and those with hepatic or renal impairment. Adjustments in dosing may be necessary to ensure both safety and efficacy.
The elderly may have altered pharmacokinetics, and their healthcare providers should monitor them closely for potential adverse reactions. Similarly, patients with liver or kidney conditions may require dosage modifications.
Consultation with a specialist in oncology can provide guidance on how to best manage these populations while using VITRAKVI.
What were the findings of the clinical trials for VITRAKVI?
Clinical trials for VITRAKVI involved 279 participants, revealing diverse tumor types and patient demographics. The median age of participants was 46, with 33% of patients being under 18 years old.
Findings indicated that the most frequent adverse reactions primarily involved elevated liver enzymes, anemia, and fatigue. Monitoring during these trials demonstrated that over 20% of patients needed close observation for laboratory abnormalities due to these side effects.
These clinical results highlight the importance of regular monitoring and laboratory assessments as part of the treatment protocol for VITRAKVI, ensuring timely intervention when adverse reactions occur.
What monitoring is required during VITRAKVI treatment?
Monitoring is a critical component of treatment with VITRAKVI 25mg hard capsules. Patients should undergo regular evaluations to identify any potential adverse reactions or laboratory abnormalities. Essential monitoring components include:
- Frequent liver function tests to assess enzyme levels.
- Complete blood counts to monitor for anemia.
- Assessment of musculoskeletal symptoms.
Close observation is crucial, especially in the initial months of treatment, as this is when serious adverse events are most likely to occur. Healthcare providers should develop a comprehensive monitoring plan tailored to individual patient needs.

What are the ingredients in Vitrakvi?
VITRAKVI contains the active ingredient larotrectinib sulfate, which is responsible for its therapeutic effects against tumors with NTRK gene fusions. Inactive ingredients may also be included in the capsule formulation but typically do not contribute to the therapeutic action.
What does Vitrakvi do?
VITRAKVI functions by specifically targeting and inhibiting the activity of proteins produced by the NTRK gene, effectively blocking signaling pathways that lead to tumor growth. This targeted mechanism allows for a more personalized approach to cancer treatment, especially in tumors that exhibit NTRK fusions.
How effective is Vitrakvi?
Clinical trials indicate that VITRAKVI is highly effective in treating solid tumors with NTRK gene fusions. The results demonstrate a significant response rate among patients, making it a promising alternative to traditional chemotherapy for eligible individuals.
What is the brand name for Vitrakvi?
The brand name for VITRAKVI is derived from its active ingredient, larotrectinib. This name is recognized in the medical community as a targeted therapy specifically for NTRK gene fusion-positive cancers.
