Key inclusion & exclusion criteria
Inclusion criteria:
1) Signed written informed consent
2) Subject must have had CD for at least 3 months from the time of initial diagnosis.
Active CD must be confirmed by radiologic, endoscopic or histologic evidence within
the previous 12 months. If previous confirmation of diagnosis is not available or if
previous diagnosis is not deemed conclusive at time of screening, CD diagnosis
should be confirmed by endoscopy, radiology or histology.
3) Subjects must satisfy at least one of the following criteria:
a/ Having had an inadequate response to at least 1 of the following treatments
(subjects may be currently receiving 1 of these medications or have received them
previously):
i) oral aminosalicylates (e.g., mesalamine, sulfasalazine, olsalazine, balsalizide)
at or above the approved label dose for at least 8 weeks and/or
ii) oral prednisone >= 30 mg/day (or equivalent) or budesonide >= 9 mg/day for at
least 4 weeks and/or
iii) immunosuppressants (azathioprine >= 2 mg/kg/day or 6-mercaptopurine >=
1.0 mg/kg/day [or documentation of a therapeutic concentration of
6-thioguanine nucleotide] or methotrexate >= 15 mg/week) for at least 12
weeks and/or
iv) an approved anti-TNF agent at an approved labeled dose for at least 8 weeks
AND/OR
b/ Have been intolerant to one of the above mentioned treatments (e.g., unable to
achieve doses or treatment durations because of dose limiting side effects [e.g.,
leukopenia]).
Subjects currently receiving and tolerating the above mentioned treatments (with
the exception of anti-TNF agents) should continue their treatment (see Drug Stabilization Requirements, Protocol Section 6.4.2.1). Subjects who had an inadequate response and/or intolerance to anti-TNF treatment must have had their last dose at least 8 weeks prior to entry into the Induction Period.
Acceptable documentation of inadequate response or intolerance in subjects include 1 or more of the following: medical records; letters provided by the referring physician; other referral documents (e.g., insurance authorization forms), provided they contain the relevant information to support the subject’s ‘inadequate response’ and/or ‘intolerance’ to the designated therapy.
In all circumstances, it should be established that discontinuation of the designated
treatments was primarily due to lack of efficacy or intolerance (e.g., not due to
unavailability of the drug).
Subjects in clinical remission should not discontinue CD therapy that is maintaining
clinical remission, for the purpose of meeting eligibility requirements to enroll into this
study.
4) Moderate to severe CD as measured by a CDAI score >= 220 and =< 450
5) hsCRP > Upper Limit of Normal (ULN)
6) Oral corticosteroid treatment must have been reduced to the equivalent of =< 30 mg prednisone or =< 9 mg budesonide daily at a stable dose for at least 2 weeks prior to entry into the Induction Period
7) Oral aminosalicylates should be at a stable dose for at least 2 weeks prior to entry into the Induction Period
8) Azathioprine, 6-mercaptopurine and methotrexate should be at a stable dose for at least 8 weeks prior to entry into the Induction Period

Primary Outcome(s)
Secondary Objective: Induction Period (IP):
-Compare proportion of subjects in clinical remission at both Day IP-57 & IP-85 between abatacept & placebo treatment regimens
-Evaluate dose-response relationship by comparing proportions of subjects with a clinical response at both Day IP-57 & IP-85 induced by placebo & abatacept in increasing doses
-Assess improvements in quality of life at Day IP-85 using the IBD Questionnaire in abatacept vs. placebo treated subjects

Maintenance Period (MP):
-Compare proportion of subjects between abatacept & placebo treatment regimens:
• who have a clinical response at Day MP-365
• in clinical remission at both Day MP-169 & MP-365
-Assess in abatacept vs. placebo treated subjects improvements in quality of life using the SF-36 & IBD Questionnaire

*IP+MP:
Assess tolerability & safety of abatacept in subjects with CD
Assess immunogenicity of abatacept in subjects with CD


See Protocol Sections 2.1.2, 2.2.2, 2.3.2 for additional secondary objectives
Primary end point(s): * The Induction Period’s primary efficacy assessment will test for differences in the proportion of subjects in the Induction Period abatacept 30/~10mg/kg treatment regimen versus placebo and abatacept ~10mg/kg treatment regimen versus placebo who are in clinical response on Days IP-71 and IP-85. The Induction Period’s two primary comparisons will be tested using the Cochran-Mantel-Haenszel (CMH) Chi-square test at the 5% level of significance with stratification according to the Induction Period stratification factors:
1) disease severity, and
2) concomitant use of immunosuppressants.


* The primary efficacy assessment of the Maintenance Period will test for treatment differences in the proportion of subjects who are in clinical remission at Day MP-365. The CMH Chi-square test will be used to compare the two treatment groups at the 5% level of significance, with stratification according to the Maintenance Period stratification factors:
1) disease activity following Induction therapy, and
2) concomitant use of immunosuppressants.


* Safety Analysis:
Significant physical examination findings, and clinical and laboratory test results will be listed. Summary statistics will be tabulated. Frequency distributions and individual
listings of all adverse events will be generated. Changes from baseline in clinical
laboratory test results will be listed.

* PK Analysis:
Summary statistics will be tabulated for PK parameters by dose groups. Geometric means and coefficients of variation will be presented for Cmax, Cmin and AUC (TAU).
Medians and ranges (minimum and maximum) will be presented for Tmax.
Main Objective: * Placebo-Controlled Induction Period:
Compare the proportion of subjects who have a clinical response (as defined by a reduction in Crohn’s Disease Activity Index [CDAI] >= 100 or an absolute CDAI score < 150) at both Day IP-57 (Week 8) and Day IP-85 (Week 12) between the abatacept and placebo treatment regimens.

* Maintenance Period:
Compare the proportion of subjects who are in clinical remission
(CDAI < 150) at Day MP-365 (12 months) between the abatacept and placebo treatment regimens.

* Open-label Extension Phase:
Assess the long-term clinical safety and tolerability of abatacept treatment.
