Detailed description: This is a double-blind, randomised, two-treatment cross-over study in healthy adult subjects to compare the safety, tolerability, pharmacokinetics and pharmacodynamics of PF530 and Betaferon. Half of the subjects will be randomised to receive PF530 first and Betaferon second, and the other half will be randomised to receive the drugs in reverse sequence. Each study participant will complete two 7-day study periods (Period 1 and Period 2), separated by a 14-day washout period. In Part I of the study, 12 subjects will be enrolled for an initial assessment. In Part II, up to 36 additional subjects may be enrolled.


Minimum age: 18 Years. Maximum age: 50 Years. Gender(s): Both.

control, practice complete abstinence, or confirm sterilization of monogamous male partner

- Males must have had a documented vasectomy, practice complete abstinence or use a

condom and refrain from sperm.

- Participant is free from clinically significant illness or disease as determined by

medical and surgical history, physical examination, 12-lead electrocardiogram (ECG) and clinical laboratory assessments.

- Able to understand and sign the written Informed Consent Form

Exclusion Criteria:

- Female subjects who are pregnant or lactating.

- History of epilepsy, seizure disorder or any unexplained black-outs.

- History of hypersensitivity or intolerance to paracetamol or non-steroidal

anti-inflammatory drugs (NSAID) that would preclude the use of at least 1 of these during the study.

- History of tobacco use less than or equal to 6 months prior to Screening.

- A positive test for drugs of abuse or alcohol during Screening or prior to dosing.

- Unwilling or unable to abstain from alcohol from 7 days prior to dosing until

end-of-study assessments.
