Title: A Phase II, Multicenter, Randomised, Double-blind, Placebo Controlled, Dose Finding Study of Subcutaneously Administered Interferon Beta-1a for Maintenance of Remission in Patients With Crohn's Disease
Brief Summary: The purpose of this study is to determine the safety and efficacy of interferon beta-1a in maintaining remission in patients with Crohn's disease.


Options:
A: Inclusion Criteria:

* Diagnosis of ileal, colonic (including rectal), or ileocolonic Crohn's disease (CD) confirmed using imaging technology or endoscopy not more than 6 years prior to Baseline.
* CDAI score of greater than or equal to 220 and less than or equal to 450 at the Baseline visit in participants not receiving prednisone or equivalent at Baseline. CDAI score of greater than or equal to 200 and less than or equal to 450 at the Baseline visit if the participant is receiving prednisone less than or equal to 20 mg or equivalent for at least 7 days before Baseline. CDAI score of greater than 150 and less than or equal to 450 at the Baseline visit if the participant is receiving prednisone higher than 20 mg or equivalent for greater than or equal to 7 days before Baseline
* Participant or his/her legal representative have voluntarily signed and dated an informed consent approved by and compliant with the requirements of this study protocol which has been approved by an Institutional Review Board (IRB)/Independent Ethics Committee (IEC).
* Adequate cardiac, renal and hepatic function as determined by the Principal Investigator and demonstrated by Screening laboratory evaluations, questionnaires and physical examination results that do not indicate an abnormal clinical condition which would place the participant at undue risk and thus preclude participation in the study.
* Participant must be able to self-inject and orally administer study medication or have a designee or Healthcare Professional who can assist

Exclusion Criteria:

* Previous or current biologic use for Crohn's disease or participation in a biologic study
* Previous or current use of immunomodulators (e.g., methotrexate, azathioprine, 6-mercaptopurine, JAK inhibitor, alpha-integrin) for Crohn's disease or participation in a Crohn's disease study with immunomodulator(s). Current use of immunomodulators for non-Crohn's disease at Baseline.
* Greater than two previous courses of corticosteroid (systemic corticosteroid) or budesonide) for Crohn's Disease. A course is defined as 1) total duration for burst and taper ≥ 4 weeks and 2) prednisone or equivalent ≥ 40 mg (or budesonide ≥ 9 mg) for at least 2 weeks.
* Participants with a poorly controlled medical condition such as: uncontrolled diabetes with documented history of recurrent infections, unstable ischemic heart disease, moderate to severe congestive heart failure (New York Heart Association \[NYHA\] class III or IV), recent cerebrovascular accident and any other condition which, in the opinion of the Investigator or the sponsor, would put the participant at risk by participation in the protocol
* Participants with positive C. difficile stool assay at Screening.
B: Inclusion Criteria:

* Patients with an established diagnosis of Crohn's disease who went into remission using corticosteroids within 4 weeks before the study

Exclusion Criteria:

* Any other treatment for the maintenance of remission of Crohn's disease
C: Inclusion Criteria:

* Ulcerative colitis \>3 months duration
* Active mild-moderate ulcerative colitis (Mayo 4-10)
* Ulcerative colitis of any extent except isolated proctitis \< 5cm
* Live within driving distance of clinical site (to attend multiple study visits)

Exclusion Criteria:

* Pregnancy
* Active gastrointestinal infection
* Other gastrointestinal disease / comorbidities
* Prior colonic surgery
* Recent antibiotic or probiotic use
* Prednisone \> 20mg
* Monoclonal antibody immunosuppressive therapy
D: Inclusion Criteria:

1. Age 18 to 80
2. Diagnosis of moderately to severely active Crohn's disease (CD)
3. CD involvement of the ileum and/or colon
4. Demonstrated, over the previous 5 year period, an inadequate response to, loss of response to, or intolerance of at least 1 of the following agents, within protocol-specified parameters:

   1. Immunomodulators
   2. Tumor necrosis factor-alpha (TNFα) antagonists
   3. Corticosteroids
5. May be receiving a therapeutic dose of conventional therapies for irritable bowel disease (IBD) defined by the protocol

Exclusion Criteria

1. Evidence of abdominal abscess at the initial screening visit, other than a minimum of 10 aphthous ulcerations involving a minimum of 10 contiguous cm of intestine
2. Extensive colonic resection, subtotal or total colectomy
3. History of \>3 small bowel resections or diagnosis of short bowel syndrome
4. Ileostomy, colostomy, or known fixed symptomatic stenosis of the intestine
5. Have received non permitted IBD therapies within either 30 or 60 days, depending on the medication, as stated in the protocol
6. Chronic hepatitis B or C infection
7. Active or latent tuberculosis

Answer: B
