Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |
|
Reaction Conditions |
12 h; IC50=21.3 nM (MP cells); cell survival rate of 50.0±0.6%=22.4 nM (SP cells) |
|
Applications |
The inhibitory effects of crizotinib on MP cells and SP cells were determined by colony formation assay. The IC50 value of crizotinib for MP cells was 21.3 nM. Of note, the SP cells showed no significant changes after crizotinib treatment. However, the SP cells showed a cell survival rate of 50.0±0.6% following a combined treatment of crizotinib (22.4 nM) and verapamil (500 µM), compared with 105.3±0.4% survival of SP cells treated with crizotinib (22.4 nM) alone. The growth curves obtained demonstrate that crizotinib inhibited the growth of SP and MP cells, and this inhibition was dependent on both concentration and time. |

First-Line Lorlatinib or Crizotinib in Advanced ALK-Positive Lung Cancer
Background: Lorlatinib, a third-generation inhibitor of anaplastic lymphoma kinase (ALK), has antitumor activity in previously treated patients with ALK-positive non-small-cell lung cancer (NSCLC). The efficacy of lorlatinib, as compared with that of crizotinib, as first-line treatment for advanced ALK-positive NSCLC is unclear. Methods: We conducted a global, randomized, phase 3 trial comparing lorlatinib with crizotinib in 296 patients with advanced ALK-positive NSCLC who had received no previous systemic treatment for metastatic disease. The primary end point was progression-free survival as assessed by blinded independent central review. Secondary end points included independently assessed objective response and intracranial response. An interim analysis of efficacy was planned after approximately 133 of 177 (75%) expected events of disease progression or death had occurred. Results: The percentage of patients who were alive without disease progression at 12 months was 78% (95% confidence interval [CI], 70 to 84) in the lorlatinib group and 39% (95% CI, 30 to 48) in the crizotinib group (hazard ratio for disease progression or death, 0.28; 95% CI, 0.19 to 0.41; P<0.001). An objective response occurred in 76% (95% CI, 68 to 83) of the patients in the lorlatinib group and 58% (95% CI, 49 to 66) of those in the crizotinib group; among those with measurable brain metastases, 82% (95% CI, 57 to 96) and 23% (95% CI, 5 to 54), respectively, had an intracranial response, and 71% of the patients who received lorlatinib had an intracranial complete response. The most common adverse events with lorlatinib were hyperlipidemia, edema, increased weight, peripheral neuropathy, and cognitive effects. Lorlatinib was associated with more grade 3 or 4 adverse events (mainly altered lipid levels) than crizotinib (in 72% vs. 56%). Discontinuation of treatment because of adverse events occurred in 7% and 9% of the patients, respectively. Conclusions: In an interim analysis of results among patients with previously untreated advanced ALK-positive NSCLC, those who received lorlatinib had significantly longer progression-free survival and a higher frequency of intracranial response than those who received crizotinib. The incidence of grade 3 or 4 adverse events was higher with lorlatinib than with crizotinib because of the frequent occurrence of altered lipid levels.

Brigatinib Versus Crizotinib in ALK Inhibitor-Naive Advanced ALK-Positive NSCLC: Final Results of Phase 3 ALTA-1L Trial
Introduction: In the phase 3 study entitled ALK in Lung cancer Trial of brigAtinib in 1st Line (ALTA-1L), which is a study of brigatinib in ALK inhibitor-naive advanced ALK-positive NSCLC, brigatinib exhibited superior progression-free survival (PFS) versus crizotinib in the two planned interim analyses. Here, we report the final efficacy, safety, and exploratory results.
Methods: Patients were randomized to brigatinib 180 mg once daily (7-d lead-in at 90 mg once daily) or crizotinib 250 mg twice daily. The primary end point was a blinded independent review committee-assessed PFS. Genetic alterations in plasma cell-free DNA were assessed in relation to clinical efficacy.
Results: A total of 275 patients were enrolled (brigatinib, n = 137; crizotinib, n = 138). At study end, (brigatinib median follow-up = 40.4 mo), the 3-year PFS by blinded independent review committee was 43% (brigatinib) versus 19% (crizotinib; median = 24.0 versus 11.1 mo, hazard ratio [HR] = 0.48, 95% confidence interval [CI]: 0.35-0.66). The median overall survival was not reached in either group (HR = 0.81, 95% CI: 0.53-1.22). Posthoc analyses suggested an overall survival benefit for brigatinib in patients with baseline brain metastases (HR = 0.43, 95% CI: 0.21-0.89). Detectable baseline EML4-ALK fusion variant 3 and TP53 mutation in plasma were associated with poor PFS. Brigatinib exhibited superior efficacy compared with crizotinib regardless of EML4-ALK variant and TP53 mutation. Emerging secondary ALK mutations were rare in patients progressing on brigatinib. No new safety signals were observed.
Conclusions: In the ALTA-1L final analysis, with longer follow-up, brigatinib continued to exhibit superior efficacy and tolerability versus crizotinib in patients with or without poor prognostic biomarkers. The suggested survival benefit with brigatinib in patients with brain metastases warrants future study.
Crizotinib
Crizotinib is an ATP-competitive small-molecule inhibitor of the receptor tyrosine kinases (RTK) C-Met, ALK and ROS1. There is a robust effectiveness in non-small-cell lung cancer (NSCLC) harbouring EML4-ALK-rearrangements resulting in constitutional activation of the ALK-RTK. The drug is approved for this entity, which represents no more than 3-5% of all NSCLC. However, in this population, impressive response rates are generated. The same is true for ROS-1 rearrangements; however, these only occur in approximately 1% of all NSCLC. In small series, efficacy is also reported in patients, whose tumours harbour a MET Exon 4 skipping mutation (approx. 3% of all NSCLC). Toxicities include visual impairment, nausea, peripheral edema, QT-prolongation and liver-enzyme elevation. Also, the occurrence of renal cysts is reported. The detection of ALK-protein by immunohistochemistry is a predictor of efficacy for crizotinib. In cases of doubt, fluorescence in situ hybridisation (FISH) detecting the ALK-rearrangement has to be performed on tumour tissue. FISH is also the method of choice to detect ROS1-rearrangement, whereas MET-mutations are detected by sequencing methods. The high efficacy of crizotinib in ALK- and ROS-rearranged as well as MET mutated lung cancer as new molecular targets beside the epidermal growth factor receptor (EGFR) underscores the importance of molecular typing in NSCLC.
Brigatinib versus Crizotinib in ALK-Positive Non-Small-Cell Lung Cancer
Background: Brigatinib, a next-generation anaplastic lymphoma kinase (ALK) inhibitor, has robust efficacy in patients with ALK-positive non-small-cell lung cancer (NSCLC) that is refractory to crizotinib. The efficacy of brigatinib, as compared with crizotinib, in patients with advanced ALK-positive NSCLC who have not previously received an ALK inhibitor is unclear.
Methods: In an open-label, phase 3 trial, we randomly assigned, in a 1:1 ratio, patients with advanced ALK-positive NSCLC who had not previously received ALK inhibitors to receive brigatinib at a dose of 180 mg once daily (with a 7-day lead-in period at 90 mg) or crizotinib at a dose of 250 mg twice daily. The primary end point was progression-free survival as assessed by blinded independent central review. Secondary end points included the objective response rate and intracranial response. The first interim analysis was planned when approximately 50% of 198 expected events of disease progression or death had occurred.
Results: A total of 275 patients underwent randomization; 137 were assigned to brigatinib and 138 to crizotinib. At the first interim analysis (99 events), the median follow-up was 11.0 months in the brigatinib group and 9.3 months in the crizotinib group. The rate of progression-free survival was higher with brigatinib than with crizotinib (estimated 12-month progression-free survival, 67% [95% confidence interval {CI}, 56 to 75] vs. 43% [95% CI, 32 to 53]; hazard ratio for disease progression or death, 0.49 [95% CI, 0.33 to 0.74]; P<0.001 by the log-rank test). The confirmed objective response rate was 71% (95% CI, 62 to 78) with brigatinib and 60% (95% CI, 51 to 68) with crizotinib; the confirmed rate of intracranial response among patients with measurable lesions was 78% (95% CI, 52 to 94) and 29% (95% CI, 11 to 52), respectively. No new safety concerns were noted.
Conclusions: Among patients with ALK-positive NSCLC who had not previously received an ALK inhibitor, progression-free survival was significantly longer among patients who received brigatinib than among those who received crizotinib.

Crizotinib in Patients With MET-Amplified NSCLC
Introduction: MET amplification is a rare, potentially actionable, primary oncogenic driver in patients with NSCLC.
Methods: The influence of MET amplification on the clinical activity of the ALK, ROS1, and MET inhibitor, crizotinib (250 mg twice daily), was examined in patients with NSCLC (NCT00585195) who were enrolled into high (≥4 MET-to-CEP7 ratio), medium (>2.2 to <4 MET-to-CEP7 ratio), or low (≥1.8 to ≤2.2 MET-to-CEP7 ratio) amplification categories. Retrospective next-generation sequencing profiling was performed on archival tumor tissue. End points included objective response rate (ORR), duration of response, and progression-free survival.
Results: A total of 38 patients with a MET-to-CEP7 ratio greater than or equal to 1.8 by local fluorescence in situ hybridization testing received crizotinib. All patients were response-assessable, among whom 21, 14, and 3 had high, medium, and low MET amplification, respectively. ORRs of 8 of 21 (38.1%), 2 of 14 (14.3%), and 1 of 3 (33.3%), median duration of response of 5.2, 3.8, and 12.2 months, and median progression-free survival values of 6.7, 1.9, and 1.8 months were observed for those with high, medium, and low MET amplification, respectively. MET amplification gene copy number greater than or equal to 6 was detected by next-generation sequencing in 15 of 19 (78.9%) analyzable patients. Of these 15 patients, objective responses were observed in six (40%), two of whom had concurrent MET exon 14 alterations. No responses were observed among five patients with concurrent KRAS, BRAF, or EGFR mutations.
Conclusions: Patients with high-level, MET-amplified NSCLC responded to crizotinib with the highest ORR. Use of combined diagnostics for MET and other oncogenes may potentially identify patients most likely to respond to crizotinib.
