Brief Summary

This is a multicenter, Phase 1b, randomized, double-blind, placebo-controlled, sequential-cohort, multiple ascending dose (MAD) study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of 3 subcutaneous and 1 intravenous dose of E6011 in subjects with active Crohn's disease (CD). Thirty-two subjects will be randomized to one of 4 dose cohorts (8 per cohort) and will receive E6011 or placebo for 10 weeks. The first 3 cohorts will receive E6011 or placebo via subcutaneous injection and the last cohort will receive E6011 or placebo by intravenous injection. The ratio of E6011 to placebo within each cohort will be 3:1. The study has 2 phases: Prerandomization and Randomization.

Eligibility Criteria

Inclusion Criteria

Subjects must meet all of the following criteria to be included in this study:

1. Male or female subjects age greater than or equal to 18 years old at the time of informed consent

2. Confirmed diagnosis of CD, with at least one documented lesion within the reach of a colonoscope (terminal ileal or ileo-colonic or colonic) from a previous colonoscopy, for a minimum duration of 6 months at the time of screening

3. Active CD with a CD activity index (CDAI) score greater than or equal to 220 and less than or equal to 450

Exclusion Criteria

5. Inadequate response to, loss of response to, or intolerance of at least one of the following agents as defined below:

• Immunomodulators:
• Signs and symptoms of persistently active disease despite a history of at least one 8-week regimen of oral azathioprine (AZA) (greater than or equal to 1.5 mg/kg) or 6-mercaptopurine (6-MP) mg/kg (greater than or equal to 0.75 mg/kg) OR
• Signs and symptoms of persistently active disease despite a history of at least one 8-week regimen of methotrexate (MTX) (greater than or equal to 12.5 mg/week)
• History of intolerance to at least 1 immunomodulator (including, but not limited to) nausea/vomiting, abdominal pain, pancreatitis, liver function test (LFT) abnormalities, lymphopenia, thiopurine methyltransferase (TPMT) genetic mutation, infection
• Tumor Necrosis Factor (TNF)-alpha antagonists:
• Signs and symptoms of persistently active disease despite a history of at least one 4-week induction regimen of one of the following agents:
• Infliximab: 5 mg/kg IV, 2 doses at least 2 weeks apart
• Adalimumab: one 80 mg SC dose followed by one 40-mg dose at least 2 weeks apart
• Certolizumab pegol: 400 mg SC dose, 2 doses at least 2 weeks apart OR
• Recurrence of symptoms during scheduled maintenance dosing following prior clinical benefit (discontinuation despite clinical benefit does not qualify)
• History of intolerance to at least 1 TNF antagonist (including, but not limited to infusion-related reaction, demyelination, congestive heart failure, infection)

6. C-reactive protein greater than or equal to 5 mg/L at screening or fecal calprotectin greater than or equal to 250 ug/g

7. Females must not be breastfeeding or pregnant at Screening (as documented by a negative beta-human chorionic gonadotropin [B-hCG]). A separate baseline assessment is required if a negative screening pregnancy test was obtained more than 72 hours before the first dose of study drug.

8. Females of childbearing potential must not have had unprotected sexual intercourse within 30 days before study entry and must agree to use a highly effective method of contraception (eg, total abstinence, an intrauterine device, a double-barrier method [such as condom plus diaphragm with spermicide], a contraceptive implant, an oral contraceptive, or have a vasectomized partner with confirmed azoospermia) throughout the entire study period and for 70 days after study drug discontinuation. If currently abstinent, the subject must agree to use a double-barrier method as described above if she becomes sexually active during the study period or for 70 days after study drug discontinuation. Females who are using hormonal contraceptives must have been on a stable dose of the same hormonal contraceptive product for at least 4 weeks before dosing and must continue to use the same contraceptive during the study and for 70 days after study drug discontinuation. All females will be considered to be of childbearing potential unless they are postmenopausal (amenorrheic for at least 12 consecutive months, in the appropriate age group, and without other known or suspected cause) or have been sterilized surgically (ie, bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing).
