What Is Rozlytrek?

Rozlytrek (entrectinib) is a kinase inhibitor indicated for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) whose tumors are ROS1-positive; and adult and pediatric patients 12 years of age and older with solid tumors that have a neurotrophic tyrosine receptor 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 progressed following treatment or have no satisfactory alternative therapy.

What Are Side Effects of Rozlytrek?

Common side effects of Rozlytrek include:

Dosage for Rozlytrek

The recommended dosage of Rozlytrek for ROS1-Positive non-small cell lung cancer is 600 mg orally once daily. The recommended adult dosage of Rozlytrek for NTRK gene fusion-positive solid tumors is 600 mg orally once daily. The recommended dosage of Rozlytrek is based on body surface area.

What Drugs, Substances, or Supplements Interact with Rozlytrek?

Rozlytrek may interact with grapefruit and grapefruit products, strong or moderate CYP3A inhibitors or inducers, and medications that prolong the QT/QTc interval. Tell your doctor all medications and supplements you use.

Rozlytrek During Pregnancy and Breastfeeding

Rozlytrek is not recommended for use during pregnancy; it may harm a fetus. Females of reproductive potential are advised to use effective contraception during treatment with Rozlytrek and for 5 weeks following the final dose. Males with female partners of reproductive potential are advised to use effective contraception during treatment with Rozlytrek and for 3 months after the final dose. It is unknown if Rozlytrek passes into breast milk. Because of the potential adverse reactions in breastfed children, breastfeeding is not recommended during treatment with Rozlytrek and for 7 days after the final dose.

The following clinically significant adverse reactions are described elsewhere in the labeling:

  • Congestive Heart Failure [see WARNINGS AND PRECAUTIONS]
  • Central Nervous System Effects [see WARNINGS AND PRECAUTIONS]
  • Skeletal Fractures [see WARNINGS AND PRECAUTIONS]
  • Hepatotoxicity [see WARNINGS AND PRECAUTIONS]
  • Hyperuricemia [see WARNINGS AND PRECAUTIONS]
  • QT Interval Prolongation [see WARNINGS AND PRECAUTIONS]
  • Vision Disorders [see WARNINGS AND PRECAUTIONS]

Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Data in WARNINGS AND PRECAUTIONS and below reflect exposure to ROZLYTREK in 355 patients, including 172 (48%) patients exposed for 6 months or longer and 84 (24%) patients exposed for 1 year or longer. ROZLYTREK was studied in one dose-finding trial in adults [ALKA (n = 57)], one dose-finding and activity-estimating trial in adults [STARTRK-1 (n = 76)], one dose-finding and activity-estimating trial in pediatric and adult patients [STARTRK-NG (n = 16)], and one single arm, activity-estimating trial in adults [STARTRK-2 (n = 206)].

The population characteristics were: median age 55 years (range: 4 to 86 years); 5% (n = 17) were less than 18 years of age; 55% were female; and 66% were White, 23% were Asian, and 5% were Black; 3% were Hispanic/Latino. The most common tumors (≥ 5%) were lung (56%), sarcoma (8%), and colon (5%). ROS1 gene fusions were present in 42% and NTRK gene fusions were present in 20%. Most adults (75%) received ROZLYTREK 600 mg orally once daily. The doses ranged from 100 mg/m² to 1600 mg/m² once daily in adults and 250 mg/m² to 750 mg/m² once daily in pediatric patients. ROZLYTREK is not indicated for pediatric patients less than 12 years of age [see Use In Specific Populations].

Serious adverse reactions occurred in 39% of patients. The most frequent serious adverse reactions (≥ 2%) were pneumonia (3.9%), dyspnea (3.7%), pleural effusion (3.4%), sepsis (2.5%), pulmonary embolism (2.3%), respiratory failure (2%), and pyrexia (2%). Grade 3 or 4 adverse reactions occurred in 60% of patients; the most common (≥ 2%) were lung infection (5%), increased weight (7%), dyspnea (6%), fatigue/asthenia (5%), cognitive disorders (4.5%), syncope (2.5%), pulmonary embolism (3.4%), hypoxia (3.4%), pleural effusion (3.1%), hypotension (2.8%), diarrhea (2%), and urinary tract infection (2.5%). Fatal events included dyspnea (0.6%), pneumonia (0.6%), sepsis (0.6%), completed suicide (0.3%), large intestine perforation (0.3%) and tumor lysis syndrome (0.3%). One patient developed Grade 4 myocarditis after one dose of ROZLYTREK which resolved after discontinuation of ROZLYTREK and administration of high-dose corticosteroids.

Permanent discontinuation due to an adverse reaction occurred in 9% of patients who received ROZLYTREK. The most frequent adverse reactions (< 1% each) that resulted in permanent discontinuation were pneumonia, cardio-respiratory arrest, dyspnea, and fatigue.

Dose interruptions due to adverse reactions occurred in 46% of patients. The most frequent adverse reactions (≥ 2%) that resulted in interruption were increased blood creatinine (4%), fatigue (3.7%), anemia (3.1%), diarrhea (2.8%), pyrexia (2.8%), dizziness (2.5%), dyspnea (2.3%), nausea (2.3%), pneumonia (2.3%), cognitive disorder (2%) and neutropenia (2%).

Dose reductions due to adverse reactions occurred in 29% of patients who received ROZLYTREK. The most frequent adverse reactions resulting in dose reductions (≥ 1%) were dizziness (3.9%), increased blood creatinine (3.1%), fatigue (2.3%), anemia (1.7%), and increased weight (1.4%).

The most common adverse reactions (≥ 20%) were fatigue, constipation, dysgeusia, edema, dizziness, diarrhea, nausea, dysesthesia, dyspnea, myalgia, cognitive impairment, increased weight, cough, vomiting, pyrexia, arthralgia and vision disorders.

Table 4 summarizes the adverse reactions observed in these 355 patients.
