Subjects must satisfy the following criteria to be enrolled in the study:

  1. Subjects who are not in clinical response or clinical remission after completing 12 weeks in the Induction Studies RPC01-3201 or RPC01-3202, subjects who experience relapse or who complete the Maintenance Study RPC01-3203, and subjects who complete a study of ozanimod for Crohn's Disease and meet the criteria for participation in the RPC01-3204 Study will have the opportunity to participate in this study.
  2. Must be male or female subjects aged 18 to 75 years (at Pre-baseline), inclusive.
  3. Subject must provide written informed consent prior to any study-related procedures, and have the ability to comply with the Table of Events.
  4. Female subjects of childbearing potential:

Must agree to practice a highly effective method of contraception throughout the study until completion of the 75-day Safety Follow-up Visit. Highly effective methods of contraception are those that alone or in combination result in a failure rate of a Pearl Index of less than 1% per year when used consistently and correctly. Acceptable methods of birth control in the study are the following:

  • Combined hormonal (containing oestrogen and progestogen) contraception, which may be oral, intravaginal, or transdermal
  • Progestogen-only hormonal contraception associated with inhibition of ovulation, which may be oral, injectable, or implantable
  • Placement of an intrauterine device (IUD)
  • Placement of an intrauterine hormone-releasing system (IUS)
  • Bilateral tubal occlusion
  • Vasectomised partner
  • Sexual abstinence

Male subjects:

Must agree to use a latex condom during sexual contact with women of childbearing potential while participating in the study until completion of the 75-day Safety Follow-up Visit.

All subjects:

Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhoea method are not acceptable methods of contraception. Female condom and male condom should not be used together.
