Clinical Trials 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.

The pooled safety population described in the Warnings and Precautions section reflects exposure to LORBRENA in 476 patients who received 100 mg LORBRENA once daily in Study B7461001 (N=327) and Study B7461006 (N=149). Among 476 patients who received LORBRENA, 75% were exposed for 6 months or longer and 61% were exposed for greater than 1 year. In this pooled safety population, the most frequent adverse reactions in ≥ 20% of 476 patients who received LORBRENA were edema (56%), peripheral neuropathy (44%), weight gain (31%), cognitive effects (28%), fatigue (27%), dyspnea (27%), arthralgia (24%), diarrhea (23%), mood effects (21%), and cough (21%). The most frequent Grade 3-4 laboratory abnormalities in ≥ 20% of 476 patients who received LORBRENA were hypercholesterolemia (21%) and hypertriglyceridemia (21%).

Previously Untreated ALK-Positive Metastatic NSCLC (CROWN Study)

The safety of LORBRENA was evaluated in 149 patients with ALK-positive NSCLC in a randomized, open-label, active-controlled trial for the treatment of patients with ALK-positive, locally advanced or metastatic, NSCLC who had not received previous systemic treatment for advanced disease. The median duration of exposure to LORBRENA was 16.7 months (4 days to 34.3 months) and 76% received LORBRENA for at least 12 months.

Serious adverse reactions occurred in 34% of patients treated with LORBRENA; the most frequently reported serious adverse reactions were pneumonia (4.7%), dyspnea (2.7%), respiratory failure (2.7%), cognitive effects (2.0%), and pyrexia (2.0%). Fatal adverse reactions occurred in 3.4% of patients treated with LORBRENA and included pneumonia (0.7%), respiratory failure (0.7%), cardiac failure acute (0.7%), pulmonary embolism (0.7%), and sudden death (0.7%).

Permanent discontinuation of LORBRENA due to adverse reactions occurred in 6.7% of patients. The most frequent adverse reaction that led to permanent discontinuation of LORBRENA was cognitive effects (1.3%). Adverse reactions leading to dose interruptions occurred in 49% of patients treated with LORBRENA. The most frequent adverse reactions that led to dose interruptions of LORBRENA were hypertriglyceridemia (7%), edema (5%), pneumonia (4.7%) cognitive effects (4.0%), mood effects (4.0%), and hypercholesterolemia (3.4%). Adverse reactions leading to dose reductions occurred in 21% of patients treated with LORBRENA. The most frequent adverse reactions that led to dose reductions were edema (5%), hypertriglyceridemia (4.0%), and peripheral neuropathy (3.4%).

Tables 1 and 2 summarize most frequent adverse reactions and laboratory abnormalities, respectively, in patients treated with LORBRENA in Study B7461006.

Previously Treated ALK-Positive Metastatic NSCLC

The data described below reflect exposure to LORBRENA in 295 patients with ALK-positive or ROS1-positive metastatic NSCLC who received LORBRENA 100 mg orally once daily in Study B7461001, a multi-cohort, non-comparative trial.The median duration of exposure to LORBRENA was 12.5 months (1 day to 35 months) and 52% received LORBRENA for ≥12 months. Patient characteristics were: median age of 53 years (19 to 85 years), age ≥65 years (18%), female (58%), White (49%), Asian (37%), and ECOG performance status 0 or 1 (96%).

The most frequent (≥20%) adverse reactions were edema, peripheral neuropathy, cognitive effects, dyspnea, fatigue, weight gain, arthralgia, mood effects, and diarrhea. Of the worsening laboratory values occurring in ≥20% of patients, the most frequent were hypercholesterolemia, hypertriglyceridemia, anemia, hyperglycemia, increased AST, hypoalbuminemia, increased ALT, increased lipase, and increased alkaline phosphatase.

Serious adverse reactions occurred in 32% of the 295 patients; the most frequently reported serious adverse reactions were pneumonia (3.4%), dyspnea (2.7%), pyrexia (2%), mental status changes (1.4%), and respiratory failure (1.4%). Fatal adverse reactions occurred in 2.7% of patients and included pneumonia (0.7%), myocardial infarction (0.7%), acute pulmonary edema (0.3%), embolism (0.3%), peripheral artery occlusion (0.3%), and respiratory distress (0.3%). Permanent discontinuation of LORBRENA for adverse reactions occurred in 8% of patients.

The most frequent adverse reactions that led to permanent discontinuation were respiratory failure (1.4%), dyspnea (0.7%), myocardial infarction (0.7%), cognitive effects (0.7%) and mood effects (0.7%). Approximately 48% of patients required dose interruption. The most frequent adverse reactions that led to dose interruptions were edema (7%), hypertriglyceridemia (6%), peripheral neuropathy (5%), cognitive effects (4.4%), increased lipase (3.7%), hypercholesterolemia (3.4%), mood effects (3.1%), dyspnea (2.7%), pneumonia (2.7%), and hypertension (2.0%). Approximately 24% of patients required at least 1 dose reduction for adverse reactions. The most frequent adverse reactions that led to dose reductions were edema (6%), peripheral neuropathy (4.7%), cognitive effects (4.1%), and mood effects (3.1%).

Tables 4 and 5 summarize most frequent adverse reactions and laboratory abnormalities, respectively, in patients treated with LORBRENA in Study B7461001.
