An open label, single-center, randomized, two-treatment, two-period, two-sequence, single dose, crossover, study under fasted and fed conditions.

This is a single-dose, open-label, randomized, crossover study to evaluate the comparative oral bioavailability of XS003 (nilotinib) Capsules 192 mg (4X 48 mg) of Xspray Pharma AB, Sweden under fasted conditions comparing with XS003 (nilotinib) Capsules 192 mg (4X 48 mg) of Xspray Pharma AB, Sweden in healthy, adult, human subjects under fed conditions.

This will enroll up to 48 healthy, adult, human subjects. Each sequence will enroll 24 healthy, adult, human subjects. There will be at least 10 days between each drug administration.

Adverse events will be recorded from the signing of ICF throughout the study. In each period, the subjects will be housed for approximately 14 hours before and at least 24 hours after the drug administration. Subjects will return to clinical facility for ambulatory samples at 48.00, 72.00, 96.00 and 120.00 hours post dose.

Inclusion Criteria:

• A willing study participant to become eligible for the study must fulfil all of the below inclusion criteria.

• Healthy, human beings 18 and 55 years of age inclusive at the time of screening.

• Subjects, having a body mass index between ≥18.0 kg/m2 and <32.0 kg/m2.

• Subjects must be able to provide written informed consent.

• Acceptable medical history, physical examination, ECG, laboratory investigations per the Investigator.

• Female subjects must meet at least one of the following requirements:

  • Agree to abstain from sexual intercourse from screening, throughout the duration of the study and for at least 90 days after the last study drug administration.
  • Have used and agree to continue to use a reliable method of contraception (e.g., hormonal contraceptives, condom with spermicide, IUD) for at least 30 days before initial dosing, throughout the duration of the study and for at least 90 days after the last study drug administration.
  • Surgically sterile (bilateral oophorectomy or hysterectomy, bilateral tubal ligation at least 3 months before initial dosing or Essure® device placement).
  • At least 1 year postmenopausal and have a documented FSH level ≥ 40 mIU/mL at screening.

• Male subjects who are not surgically sterile must agree to abstain from sexual intercourse (complete abstinence) or use appropriate contraceptive measures and agree to not impregnate a female partner(s) and not to donate sperm throughout the entire study, including the washout periods, and for at least 90 days after the last study drug administration. Examples of acceptable methods of contraception include a double-barrier method of contraception (e.g., condom with spermicide). Other forms of contraception may be acceptable, at the discretion of the Investigator.

• Clinical laboratory values should be within the laboratory's stated normal range. If not within this range, they must be without clinical significance, as determined by the Investigator (with the exception of those labs specifically listed in Section 9.2.).

• The subject is able to communicate meaningfully with study personnel and is anticipated to be able to comply fully with study procedures and must be willing and able to communicate and participate in the whole study.

• Male subjects should not donate sperm during the study and for 90 days after the last administration of IMP.
