his study will explore the safety and activity of ECP treatment with UVADEX in inducing a
clinical response (i. e., a CDAI decrease greater than or equal to 100 from baseline and/or a
CDAI < 150) over a 12-week period in moderately active Crohn’s disease (CDAI greater than or
equal to 220 to < 450) patients who are refractory or intolerant to immunosuppressants and/or
anti-TNF agents. This study will also assess response to continued treatment during a
12-week Extension Period in patients who have a clinical response at Week 12 of the Treatment
Period and elect to participate in the Extension Period.

- Patients who are receiving any of the following concomitant Crohnâs disease
medications must have been on a stable dose of these medications for the specified
period of time PRIOR TO confirmation of eligibility (this time period may include
screening): aminosalicylates, antibiotics, and immunosuppressants (i. e., 6 MP, MTX, or

Patients are considered to have failed treatment with these medications if they are
refractory or intolerant to their use, regardless of prior or ongoing treatment with
Refractoriness to immunosuppressant therapies and/or anti-TNF agents is defined as patients
continuing to have active Crohnâs disease despite prior or current treatment with one or
more of the following: AZA 2-3 mg/kg/day for 12 weeks; 6-MP 1. 0-1. 5 mg/kg/day for 12 weeks;
MTX 25 mg/wk for 8 weeks; infliximab greater than or equal to 5 mg/kg for 4 weeks (at least
one infusion); adalimumab greater than or equal to 40 mg subcutaneous (SC) for 4 weeks (at
least two injections).
Intolerance to immunosuppressants and/or anti-TNF agents is defined as patients
experiencing related side effects to one or more of the agents listed above that limit or
proscribe their use (e. g. leukopenia, hepatitis, infusion reactions, or drug-induced lupus)
at doses needed to adequately control the activity of their Crohnâs disease.
- Patients who have discontinued treatment with any of the following Crohnâs disease
medications must have done so for the specified period of time prior to confirmation
of eligibility (this time period may include screening): antibiotics,
aminosalicylates, corticosteroids, or PO budesonide for at least 2 weeks;
immunosuppressants (i. e., 6-MP, MTX, or AZA), or anti TNF agents (i. e., infliximab or
adalimumab) for at least 8 weeks; other investigative therapies - non biologics for at
least 4 weeks and biologics for at least 8 weeks.
- Patients who have fistulae are permitted, provided: patients have predominantly
luminal Crohnâs disease, and fistulae are not associated with abscess formation.

- Female patients must be: postmenopausal, surgically incapable of bearing children, or
practicing an acceptable method of birth control (acceptable methods include hormonal
contraceptives, intrauterine device, and spermicide and barrier). Abstinence or
partner/spouse sterility may also qualify at the Investigatorâs discretion. If a
female patient is of childbearing potential, she must have a negative urine pregnancy
test at screening. Male patients must also commit to using adequate contraceptive
precautions (condoms). All patients (both males and females of childbearing
potential) must commit to using adequate contraceptive precautions throughout their
participation in the study and for at least 3 months following their last ECP

cyclosporine (CSA), tacrolimus (FK506), mycophenolate mofetil (MMF), or
investigational Crohnâs disease therapies.

stable dose of a concomitant Crohnâs disease medication during the 12-week Treatment

inflammatory Crohnâs disease (e. g., bacterial or parasitic gastroenteritis, bile salt
diarrhea, or bacterial overgrowth).
- Patients with symptomatic intestinal strictures.
- Patients with stomas.
- Patients with other local manifestations of Crohnâs disease such as abscesses, or
other disease manifestations for which surgery might be indicated, or which might
preclude utilization of a CDAI to assess response to therapy (such as âshort gutâ
