In vitro studies demonstrated that CYP3A was the major enzyme involved in the metabolic clearance of ceritinib. Following oral administration of a single 750 mg radiolabeled ceritinib dose, ceritinib as the parent compound was the main circulating component (82%) in human plasma.
Elevations in serum aminotransferase levels are common during ceritinib therapy occurring in 20% to 50% of patients, but rising above 5 times the upper limit of the normal range in only 1% to 2%. Hepatic failure is said to have occurred in 0.2% of patients and to have resulted in several fatalities. Hepatotoxicity appears to be a class effect among ALK inhibitors, although liver injury appears to be more frequent and more severe with crizotinib than ceritinib or alectinib. Specific details of the liver injury associated with ceritinib such as latency, serum enzyme pattern, clinical features and course, have not been published. Other ALK inhibitors typically cause liver injury arising within days or weeks of starting therapy, and presenting abruptly with hepatocellular enzyme elevations and a moderate-to-severe course. Immunoallergic and autoimmune features are not common. The rate of clinically significant liver injury and hepatic failure is increased in patients with preexisting cirrhosis or hepatic impairment due to liver tumor burden. Recurrence upon reexposure has been reported.
There is not currently any data on carcinogenicity, effect on human fertility, or on early embryonic development. However, based on its mechanism of action, ceritinib may cause fetal harm when administered to pregnant women and should therefore be administered with effective contraception during treatment. Diarrhea, nausea, vomiting, or abdominal pain occurred in 96% of 255 patients including severe cases in 14% of patients. Drug-induced hepatotoxicity also occurred in 27% of 255 patients, presenting as alanine aminotransferase (ALT) levels greater than 5 times the upper limit of normal (ULN). Severe, life-threatening, or fatal interstitial lung disease (ILD)/pneumonitis, hyperglycaemia, and bradycardia have also been reported.

吸收
口服塞瑞替尼后,大约在4到6小时达到峰值浓度。
After oral administration of ceritinib, peak concentrations were achieved after approximately 4 to 6 hours.
Following oral administration of a single 750 mg radiolabeled ceritinib dose, 92.3% of the administered dose was recovered in the feces (with 68% as unchanged parent compound) while 1.3% of the administered dose was recovered in the urine.

分布容积
单次750毫克剂量给药后,表观分布容积(Vd/F)为4230升。
The apparent volume of distribution (Vd/F) is 4230 L following a single 750 mg dose.
The geometric mean apparent clearance (CL/F) of ceritinib was lower at steady-state (33.2 L/h) after 750 mg daily dosing than after a single 750 mg dose (88.5 L/h).

The present application relates to a process for preparation of ceritinib and intermediates thereof. Specifically, the present application relates to a process for preparation of N-(4-(1-benzyl- 1,2,3,6-tetrahydropyridin-4-yl)-2-isopropoxy-5-methylphenyl)acetamide (VC) comprising treating N-(4-(bromomethyl)-2-isopropoxy-5-methylphenyl)acetamide (IIID) with 1- benzylpiperidin-4-one (IVA). The present application also relates to a process for conversion of N-(4-(1-benzyl-1,2,3,6-tetrahydropyridin-4-yl)-2-isopropoxy-5-methylphenyl)-acetamide (VC) to ceritinib or an acid-addition salt thereof.
