Non-small cell lung cancer, or NSCLC, is a common form of lung cancer. However, a small portion of people with NSCLC—about 5%—have a change in the anaplastic lymphoma kinase, or ALK, gene.
This change in the ALK gene results in an abnormal ALK fusion protein
The abnormal protein causes this type of lung cancer, also called ALK+ NSCLC, to grow and spread to other parts of the body ( ALK+ mNSCLC )
Doctors test people who have NSCLC to find out if they are ALK+. Knowing ALK status helps doctors choose which treatment to prescribe.
An important treatment goal for people who have just learned that they have ALK+ NSCLC that has spread to other parts of the body (mNSCLC) is to help prevent their tumor from further growing or spreading for as long as possible.
Criteria | ALECENSA dose modification |
---|---|
ALT or AST elevation of >5X ULN with total bilirubin ≤2X ULN | Temporarily withhold until recovery to baseline or to ≤3X ULN, then resume at reduced dose. See dose reduction schedule. |
ALT or AST elevation >3X ULN with total bilirubin elevation >2X ULN in the absence of cholestasis or hemolysis | Permanently discontinue ALECENSA. |
Total bilirubin elevation >3X ULN | Temporarily withhold until recovery to baseline or to ≤1.5X ULN, then resume at reduced dose. See dose reduction schedule. |
Any grade treatment-related ILD/pneumonitis | Permanently discontinue ALECENSA. |
Grade 3 renal impairment | Temporarily withhold until serum creatinine recovers to ≤1.5X ULN, then resume at reduced dose. See dose reduction schedule. |
Grade 4 renal impairment | Permanently discontinue ALECENSA. |
Symptomatic bradycardia | Withhold ALECENSA until recovery to asymptomatic bradycardia or to a heart rate of ≥60 bpm. If contributing concomitant medication is identified and discontinued, or its dose is adjusted, resume ALECENSA at previous dose upon recovery to asymptomatic bradycardia or to a heart rate of ≥60 bpm. If no contributing concomitant medication is identified, or if contributing concomitant medications are not discontinued or dose modified, resume ALECENSA at reduced dose upon recovery to asymptomatic bradycardia or to a heart rate of ≥60 bpm. See dose reduction schedule. |
Bradycardiaa (life-threatening consequences, urgent intervention indicated) | Permanently discontinue ALECENSA if no contributing concomitant medication is identified. If contributing concomitant medication is identified and discontinued, or its dose is adjusted, resume ALECENSA at reduced dose upon recovery to asymptomatic bradycardia or to a heart rate of ≥60 bpm, with frequent monitoring as clinically indicated. Permanently discontinue ALECENSA in case of recurrence. See dose reduction schedule. |
CPK elevation of >5X ULN | Temporarily withhold until recovery to baseline or to ≤2.5X ULN, then resume at same dose. |
CPK elevation >10X ULN or second occurrence of CPK elevation of >5X ULN | Temporarily withhold until recovery to baseline or to ≤2.5X ULN, then resume at reduced dose. See dose reduction schedule. |
Hemolytic anemia | Withhold ALECENSA if hemolytic anemia is suspected. Upon resolution, resume at reduced dose or permanently discontinue. See dose reduction schedule. |
aHeart rate <60 bpm.
ALT=alanine transaminase; AST=aspartate transaminase; bpm=beats per minute; CPK=creatine phosphokinase; ILD=interstitial lung disease; ULN=upper limit of normal.
