Mechanism of Action

Alectinib is a tyrosine kinase inhibitor that targets ALK and RET. In nonclinical studies, alectinib inhibited ALK phosphorylation and ALK-mediated activation of the downstream signaling proteins STAT3 and AKT, and decreased tumor cell viability in multiple cell lines harboring ALK fusions, amplifications, or activating mutations.

Alecensa Indications

Indications

Adjuvant treatment of patients following tumor resection of anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC) (tumors ≥4cm or node positive) as detected by an FDA-approved test. Treatment of patients with ALK-positive, metastatic NSCLC as detected by an FDA-approved test.

Alecensa Warnings/Precautions

Warnings/Precautions

Monitor liver function tests (eg, ALT, AST, total bilirubin) every 2 weeks for the first 3 months, then monthly and as clinically indicated; test more frequently if transaminase and bilirubin elevated; withhold, resume at reduced dose, or permanently discontinue based on severity. Evaluate if presence of worsening respiratory symptoms; withhold if ILD/pneumonitis diagnosed; permanently discontinue if no other cause identified. Withhold for Grade 3 renal toxicity until recovery to ≤1.5×ULN, then resume at reduced dose; permanently discontinue if Grade 4 occurs. Monitor HR, BP regularly. If non-life-threatening symptomatic bradycardia occurs, withhold until asymptomatic or HR ≥60bpm; permanently discontinue in case(s) of recurrence or life-threatening bradycardia if no contributing concomitant medication identified. Assess CPK every 2 weeks for the first month and as clinically indicated; withhold, resume, or reduce dose based on severity. Withhold if hemolytic anemia is suspected; consider resuming at reduced dose upon resolution or permanently discontinue if confirmed. Severe hepatic or renal impairment/ESRD. Embryo-fetal toxicity. Advise to use effective contraception during and for 5 weeks (females of reproductive potential) or 3 months (males w. female partners) after the last dose. Pregnancy: exclude status prior to initiation. Nursing mothers: not recommended (during and for 1 week after the last dose).
