About

The purpose of this study is to assess the effect of food on the pharmacokinetics (PK) of a single dose of AZD1775 (printed capsules) in patients with advanced solid tumours.

Full description

This is a Phase I, open-label, randomised, 2-period crossover design study in patients with advanced solid tumours.

The purpose of this study is to assess the effect of food on the pharmacokinetics (PK) of a single dose of AZD1775 (printed capsules).In addition single dose safety and tolerability data will be gathered.

Patients will be screened within 28 days of Day 1 of the first treatment period (Period 1). Patients will take part in 2 randomised treatment sequences each separated by a washout period of at least 5 and no more than 14 days.

During Period 1, prior to administration of the first dose of study treatment, each patient will be randomised to 1 of 2 treatment sequences (Fasted-Fed or Fed-Fasted) to receive a single oral dose of 300 mg AZD1775 in each of the 2 treatment periods as follows:

• Fasted (Treatment A): Single dose 300 mg AZD1775, (3 x 100 mg, printed capsules).
• Fed (Treatment B): Single dose 300 mg AZD1775, (3 x 100 mg, printed capsules).

Pharmacokinetic and safety assessments will be obtained for up to 72 hours post-dose in each treatment period.

On completion of the study (ie, after collection of 72-hour PK sample and safety in period 2) patients will be evaluated per current assessments for their eligibility and interest to enrol into the open-label continued treatment access study (D6014C000007).

Enrollment: 31 patients

The patient will not be excluded from other aspects of the study described in the CSP, as long as all the eligibility criteria are met.

Exclusion criteria

Patients should not enter the study if any of the following exclusion criteria are fulfilled:

• Involvement in the planning and/or conduct of the study (applies to both AstraZeneca personnel and/or personnel at the study centre).
