Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Males and females ≥ 18 and ≤ 70 years of age.
2. Diagnosis of colonic, ileocolonic, or ileal Crohn's disease for ≥ 3 months confirmed by radiography, histology, and/or endoscopy at any time in the past.
3. Moderately to severely active Crohn's disease as defined by a Harvey Bradshaw

Index (HBI) ≥ 8 at baseline AND at least one of the following:
* Abnormal CRP at screening (\> Upper Limit of Normal \[ULN\] accepted lab assay)
* Elevated fecal calprotectin at screening (\> ULN accepted lab assay)
* Endoscopic evidence (colonoscopy or small bowel video capsule endoscopy) of active Crohn's ulcerations within 3 months of baseline or during screening
4. Taking a stable dose of corticosteroids (oral or anorectal) ≤ 40 mg/day, or equivalent, for at least 2 weeks prior to baseline.
5. Taking a stable dose of 5-ASA, antibiotics, anti-diarrheals, analgesics, and/or probiotics for at least 4 weeks prior to baseline.
6. Taking a stable dose of immunosuppressants for at least 8 weeks prior to baseline.
7. Have screening laboratory test results within the following parameters:

* Hemoglobin ≥ 8.5 g/dL
* WBC count ≥ 3.5 x 103 µL
* Neutrophils ≥ 1.5 x 103 µL
* Platelets ≥ 100 x 103 µL
* Serum creatinine \< 1.7 mg/dL
* AST and ALT concentrations must be within 2 times the ULN range for the laboratory conducting the test
8. Subject has a negative TB Screening Assessment (including a PPD test) and negative chest x-ray (posterior-anterior or PA and lateral view) within 2 months prior to screening.
9. If female, subject is either not of childbearing potential, defined as postmenopausal (\> 45 years of age with amenorrhea for at least 18 months) or surgically sterile (bilateral tubal ligation, bilateral oophorectomy, hysterectomy or otherwise incapable of pregnancy) or is of childbearing potential and is practicing on of the following methods of birth control:

* Implants, injectables, some intrauterine devices (IUDs), intrauterine hormone releasing system (IUS), hormonal prescription oral contraceptives, contraceptive patch, or double barrier method
* Male partner sterilization
* Not heterosexually active
10. Negative serum pregnancy test at screening and a negative urine pregnancy test at baseline.
11. If male, not surgically sterile, and heterosexually active with a woman of child bearing potential, subject must agree to use a double barrier method of birth control and not donate sperm during the study and for 12 weeks after receiving study agent.
12. Subject must be able and willing to give written informed consent and to comply with the requirements of the study protocol.

Exclusion Criteria

1. Any and all contraindications to the use of certolizumab pegol including: active or latent TB, active viral infection or chronic recurrent infections, evidence of dysplasia or history of malignancy, congestive heart failure (CHF), demyelinating disease and cytopenia.
2. Subject who previously received treatment with certolizumab pegol or previously participated in a certolizumab pegol study.
3. Has complications of Crohn's disease such as symptomatic strictures or stenoses, short bowel syndrome, or any other manifestation that might be anticipated to require surgery, could preclude the use of the HBI to assess response to therapy, or would possibly confound the ability to assess the effect of treatment with certolizumab pegol.
4. Subject has had surgical bowel resection(s) within 6 months or any other intra- abdominal surgery within 3 months prior to baseline.
5. Subject with an ostomy or ileoanal pouch.
6. Subject has received anti-TNF agents \< 8 weeks prior to baseline.
7. Subject has received other immunomodulatory biologic agents, \< 8 weeks or within 5 half-lives of agent prior to baseline, whichever is longer
8. Subject is known to be infected with HIV, Hepatitis B or Hepatitis C
9. Subject with positive Clostridium difficile (C. difficile) toxin stool assay during the Screening period.
10. Subject has severe, progressive or uncontrolled renal, hepatic, hematological, endocrine, pulmonary, cardiac, neurologic, cerebral, or psychiatric disease, or signs and symptoms
11. Has a known history or lymphoproliferative disease, including lymphoma, or signs and symptoms suggestive or possible lymphoproliferative disease, such as lymphadenopathy or splenomegaly
12. History of clinically significant drug or alcohol abuse in the 12 months prior to baseline.
13. Female subjects who are pregnant, breast-feeding, or planning to become pregnant or a man who plans to father a child while enrolled in this study or within 20 weeks after the last dose of study agent.
14. Subject is considered by the Investigator, for any reason, to be an unsuitable candidate for the study.
