- Has given written informed consent prior to screening.

- Age 18 years old or greater.

- Has confirmed diagnosis of HPS prior to screening.

- Has confirmed diagnosis of IBD prior to screening.

- The presence of active disease as defined by a SCCAI score greater than or equal to 5.

- Negative results on stool examination for culture of enteric pathogens (Salmonella,
Shigella, Yersinia, Campylobacter, Vibrio, E. coli O157/H7), Clostridium difficile

of one or a combination of the following drug doses and durations:

Corticosteroids (less than or equal to 25 milligrams Prednisone or Prednisone equivalent
per day) - greater than or equal to 4 weeks.

5-ASA Sulfasalazine - greater than or equal to 4 weeks.

Azathioprine/6-MP/thioguanine with stable dose for eight weeks - greater than or equal to
12 weeks. (NOTE: Patients receiving azathioprine/6-MP/thioguanine must have been on a
stable dose of this medication for greater than or equal to 8 weeks)

Prebiotics (dietary supplements to produce biologically active substances) - greater than
or equal to 4 weeks.

Infliximab (5 to 10 mg/kg IV) - greater than 8 weeks or no response within 4 weeks of an
induction dose of 3 infusions.

Adalimumab (40 to 80 mg subq) - greater than or equal to 4 weeks or no response within 2
weeks after induction dose of 2 injections.


A subject is excluded from the study if any of the following criteria are met:


- Has any clinically significant disease (e.g., renal, hepatic, neurological,
cardiovascular, pulmonary, endocrinology, psychiatric, hematological, urologic, or
other acute or chronic illness) that in the opinion of the investigator would make the
subject an unsuitable candidate for this trial.

- Inability to meet any of the above inclusion criteria.

- Has any of the following clinical chemistry values:

1. AST greater than 2.5 times the upper limit of normal (ULN).

2. ALT greater than 2.5 times the ULN.

3. Serum bilirubin greater than 1.5 times the ULN.

4. Serum creatinine greater than 1.5 times the ULN.

5. Alkaline phosphatase greater than 2.5 times the ULN.

- Has a PT INR greater than 1.3 or a PTT greater than 3 seconds compared to control

- Has the following cell counts:

1. Platelet count less than 80,000 or greater than 950,000.

2. White blood cell count less than 1200.

3. Neutrophil count less than 700.

- Has a current infection requiring intravenous antibiotics, a serious local infection
(e.g., cellulitis, abscess) or systemic infection (e.g., pneumonia, septicemia).

- Has a history of cancer within the past 5 years, with the exception of excised basal
cell carcinoma, squamous cell carcinoma of the skin, or cervical carcinoma in situ.

- Had a dependency for any illicit drug, chemical or alcohol within the past 5 years.

- Has a history of active tuberculosis (TB) (or a positive PPD skin test or chest x-ray
with findings suggestive of old TB infection including calcified nodular lesions,
apical fibrosis, or pleural scarring), acute or chronic hepatitis B, hepatitis C,
human immunodeficiency virus (HIV).

- History of central nervous system demyelinating disease, or systemic lupus

- Unable to keep to the scheduled appointments and other test to watch for changes in
symptoms and side effects of treatment.


- History of colectomy, partial colectomy, current ostomy, pouchitis, or small bowel
resection within the past 6 months, or short gut syndrome.

- Presence of current active bowel obstruction, intestinal perforation, known presence
of high grade stricture, history of toxic megacolon, history of colonic epithelium
high-grade dysplasia or a dysplasia-associated lesion or mass that does not resemble
an adenoma (that is a mass lesion, stricture, or broad-based tumor with dysplasia).
