Alectinib Pharmacokinetic in Patients With NSCLC

April 6, 2026 updated by: Oscar Gerardo Arrieta Rodríguez, Instituto Nacional de Cancerologia de Mexico

A Phase I/II Open-label Clinical Trial to Evaluate the Pharmacokinetics of Alectinib With Sequential Dose Escalation in Patients Diagnosed With ALK-rearranged Advanced Non-small Cell Lung Cancer.

This interventional study aims to determine the pharmacokinetics of orally administered alectinib with dose escalation from 300 mg to 600 mg twice daily in Mexican patients with advanced ALK-positive NSCLC.

The main question it aims to answer is: what will be the peak plasma concentrations of alectinib following sequential dose escalation (300, 450, and 600 mg BID) over nine weeks of pharmacokinetic evaluation (phase I) in Mexican patients with advanced ALK-rearranged NSCLC?

In phase I (on days 0, 21, and 42), oral alectinib will be administered twice per day (BID) to patients with ALK-positive NSCLC; starting with 300 mg BID in 21-day cycles and dose escalation in 150 mg increments until 600 mg BID. Blood samples will be taken before and after administration of each dose (on days 1, 22, and 43). The primary endopoints in phase I will be dose-limiting toxicity (DLT) and PK parameters (Cmax. maximum plasma concentration; Tmax: time to reach maximum concentration: AUC 1-12: area under plasma ocncentrations-time curve steady-state concentration). At the end of the last blood collection (at day 43), the evaluation of each cycle will be at 600 mg, and the participant will be discharged to continue their treatment on an outpatient basis. Phase one will finish on day 63 of the study.

In phase II, the chosen BID dose based on the phase I portion will be administrated until disease progression, development of unacceptable side effects, or withdrawal of consent. The primary endpoint in phase 2 is the overall response rate (ORR) per RECIST V.1.1.

Intervention / Treatment

Detailed Description

Alectinib will be administrated under fast conditions.

The primary endpoint of the phase II part was ORR. Other secondary endpoints in phase II are progression-free survival (PFS), overall survival (OS), intracranial response (ICR), and duration of response (DOR).

Exploratory endpoints in this follow-up analysis included the evaluation of the correlation between tumor shrinkage and PFS and chosen dose to relieve cancer symptoms.
