Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years to 60 years (Adult)
• Accepts Healthy Volunteers: Yes
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Healthy in the opinion of the investigator. Healthy is defined by the absence of evidence of any active disease or clinically significant medical condition based on a detailed medical history and examination
• Negative test results for Hepatitis B, Hepatitis C, and Human Immunodeficiency Virus (HIV)
• Females must not be pregnant or breastfeeding, and females of childbearing potential will agree to use highly-effective contraception. Females of childbearing potential must also agree to refrain from donating eggs during the treatment period and for 6 weeks after the final dose of study drug
• Males must agree to use contraception and to refrain from sperm donation from check-in (Day -1 of Period 1) to 90 days after the final dose of study drug

Exclusion Criteria:

• History of gastrointestinal surgery or other gastrointestinal disorder that might affect absorption of medicines from the gastrointestinal tract
• Presence of a clinically significant disease, illness, medical condition or disorder, or any other medical history determined by the investigator to be clinically significant and relevant. Ongoing chronic disorders which are not considered clinically significant are permissible providing they are stable
• Clinically significant change in health status, as judged by the investigator, or any major illness within the 4 weeks before screening, or clinically significant acute infection or febrile illness within the 14 days before screening
• Participation in any other clinical study involving an investigational medicinal product (IMP) or device within 30 days or 5 half-lives (if known), whichever is longer, before screening

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: F1 to F06 Crossover; Participants first randomized to this arm will receive a single oral dose of entrectinib F1 (test formulation) on Day 1 of Period 1 after a standardized meal. This dose will be followed by a minimum 14-day washout period, after which participants will receive a single oral dose of entrectinib F06 (reference formulation) under fasted conditions on Day 1 of Period 2 (Periods 1 and 2 = 6 days).	Drug: Entrectinib Test Formulation (F1); Participants will receive a single oral dose of entrectinib F1 after completion of a standardized meal.; Drug: Entrectinib Reference Formulation (F06); Participants will receive a single oral dose of entrectinib F06 after completion of a standardized meal.
Experimental: F06 to F1 Crossover; Participants first randomized to this arm will receive a single oral dose of entrectinib F06 (reference formulation) on Day 1 of Period 1 after a standardized meal. This dose will be followed by a minimum 14-day washout period, after which participants will receive a single oral dose of entrectinib F1 (test formulation) under fasted conditions on Day 1 of Period 2 (Periods 1 and 2 = 6 days).	Drug: Entrectinib Test Formulation (F1); Participants will receive a single oral dose of entrectinib F1 after completion of a standardized meal.; Drug: Entrectinib Reference Formulation (F06); Participants will receive a single oral dose of entrectinib F06 after completion of a standardized meal.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Area Under the Concentration-Time Curve Extrapolated to Infinity (AUC0-inf) of Entrectinib and M5 Metabolite	The area under the concentration-time curve extrapolated to infinity is calculated using the formula: AUC0-inf = AUC0-t + (Ct/λz) where Ct is the last measurable concentration and λz is the apparent terminal elimination rate constant. The presented values in the table are based on all 14 participants receiving the F1 formulation in a 2-way crossover pattern.	At pre-defined intervals from study Day 1 through Day 5 of each Period (Periods 1 and 2 = 6 days)
Area Under the Concentration-Time Curve (AUC0-t) of Entrectinib and M5 Metabolite	The area under the concentration-time curve calculated from Hour 0 to the last measurable concentration, calculated using the linear trapezoidal rule for increasing concentrations and the logarithmic rule for decreasing concentrations. The presented values in the table are based on all 14 participants receiving the F1 formulation in a 2-way crossover pattern.	At pre-defined intervals from study Day 1 through Day 5 of each Period (Periods 1 and 2 = 6 days)
Maximum Observed Concentration (Cmax) of Entrectinib and M5 Metabolite	The presented values in the table are based on all 14 participants receiving the F1 formulation in a 2-way crossover pattern.	At pre-defined intervals from study Day 1 through Day 5 of each Period (Periods 1 and 2 = 6 days)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs)	An adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.	Baseline through the end of study (up to clinical cut-off date 04 Feb 2019 [27 days])
