Inclusion criteria:
Subjects must satisfy the following criteria to be enrolled in the study:
1. Subject fulfilled the inclusion criteria at time of entry into the Induction Study (RPC01 3201 or RPC01-3202) and has completed the Week 12 efficacy assessments of the Induction Study.
2. Subject should not have any constraints under local regulations, must provide written informed consent prior to any study-related procedures, and must have the ability to comply with the Table of Events.
3. Subject is in clinical response (a reduction from baseline in CDAI of = 100 points or CDAI score of < 150 points) and/or clinical remission (CDAI score of < 150 points) and/or has an average daily stool frequency score = 3 and an average abdominal pain score = 1 with abdominal pain and stool frequency no worse than baseline at Week 12 of the Induction Study.
4. Female subjects of childbearing potential (FCBP):
Note: For the purposes of this study, a female subject is considered to be of childbearing potential if she 1) has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries) or 2) has not been postmenopausal for
at least 24 consecutive months (that is, has had menses at any time during the preceding 24 consecutive months).
Must agree to practice a highly effective method of contraception throughout the study until completion of the 90-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. Examples of 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
? complete sexual abstinence
Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhoea method are not acceptable methods of contraception. Counseling about pregnancy precautions and the potential risks of fetal
exposure must be conducted for FCBP. The Investigator will educate all FCBP about the different options of contraceptive methods or abstinence at Day 1, as appropriate. The subject will be re-educated every time her contraceptive measures/methods or ability to become pregnant changes. The female subject's chosen form of contraception must be effective by the time the female subject is randomized into the study (for example, hormonal contraception should be initiated at least 28 days before randomization).

Exclusion criteria:
Exclusions Related to General Health:
1. Subject has any clinically relevant cardiovascular, hepatic, neurological, pulmonary (severe respiratory disease [pulmonary fibrosis or chronic obstructive pulmonary disease]), ophthalmological,
endocrine, psychiatric, or other major systemic disease making implementation of the protocol or interpretation of the study difficult or that would put the subject at risk by participating in the study.
