Allocation: Randomized

Interventional model: Crossover Assignment

Masking: None (Open label)

---

28 participants in 2 patient groups

Form A to Form C Crossover

Experimental group

Description:

Participants first randomized to this arm will receive a single oral dose of entrectinib form A (reference form) under fasted conditions on Day 1 of each Period. This dose will be followed by a minimum 14-day washout period, after which participants will receive a single oral dose of entrectinib form C (test form) under fasted conditions on Day 1 of Period 2 (Periods 1 and 2 = 6 days).

Treatment:

Drug: Entrectinib Form C

Drug: Entrectinib Form A

Form C to Form A Crossover

Experimental group

Description:

Participants first randomized to this arm will receive a single oral dose of entrectinib form C (test form) under fasted conditions on Day 1 of each Period. This dose will be followed by a minimum 14-day washout period, after which participants will receive a single oral dose of entrectinib form A (reference form) under fasted conditions on Day 1 of Period 2 (Periods 1 and 2 = 6 days).

Treatment:

Drug: Entrectinib Form C

Drug: Entrectinib Form A
