Important Safety Information
This is not a complete list of all possible side effects. Contact your healthcare provider if you experience any unexpected symptoms. For serious or life-threatening side effects, seek emergency medical attention immediately.
6 ADVERSE REACTIONS The following adverse reactions are described elsewhere in the labeling: • Risk of Serious Hepatotoxicity with Concomitant Use of Strong CYP3A Inducers [see Warnings and Precautions (5.1) ] • Central Nervous System Effects [see Warnings and Precautions (5.2) ] • Hyperlipidemia [see Warnings and Precautions (5.3) ] • Atrioventricular Block [see Warnings and Precautions (5.4) ] • Interstitial Lung Disease/Pneumonitis [see Warnings and Precautions (5.5) ] • Hypertension [see Warnings and Precautions (5.6) ] • Hyperglycemia [see Warnings and Precautions (5.7) ] Most common (incidence ≥20%) adverse reactions and Grade 3–4 laboratory abnormalities are edema, peripheral neuropathy, weight gain, cognitive effects, fatigue, dyspnea, arthralgia, diarrhea, mood effects, hypercholesterolemia, hypertriglyceridemia, and cough.

6.1 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 [see Clinical Studies (14) ].
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.
5 WARNINGS AND PRECAUTIONS • Risk of Serious Hepatotoxicity with Concomitant Use of Strong CYP3A Inducers : Discontinue strong CYP3A inducers for 3 plasma half-lives of the strong CYP3A inducer prior to initiating LORBRENA.
( 2.4 , 5.1 ) • Central Nervous System (CNS) Effects : CNS effects include seizures, psychotic effects and changes in cognitive function, mood (including suicidal ideation), speech, mental status, and sleep.
Withhold and resume LORBRENA at same or reduced dose or permanently discontinue LORBRENA based on severity.
( 2.3 , 5.2 ) • Hyperlipidemia : Initiate or increase the dose of lipid-lowering agents.
Withhold and resume LORBRENA at same or reduced dose based on severity.
Like all medications, Lorbrena can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
