Details and patient eligibility

About

Primary Objective:

To assess the efficacy of SAR339658

Secondary Objective:

To assess the safety of SAR339658

Full description

The study period per patient will include up to 4 weeks screening, 8 weeks treatment, 6 weeks post treatment safety follow-up, followed by a long term safety follow-up performed in the form of a phone interview at 3, 6, 12, 18 and 24 months from the last administration of the study medication.

After completion of the 8-week treatment phase, patients may be eligible to enter a long term safety study (LTS12593) for active treatment with SAR339658.

Enrollment: 28 patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers

• Patients on corticosteroids must be on a stable dose ≥2 weeks prior to screening

• Patients on azathioprine, 6- mercaptopurine or methotrexate must be on treatment for at least 12 weeks prior to screening; and on a stable dose ≥4 weeks prior to screening

• Patients on oral 5-aminosalicylates, mesalamine or sulfasalazine must be on a stable dose for ≥4 weeks prior to screening

• Patients naïve to anti-TNF alpha or non-responder (primary or secondary) or intolerant to anti-TNF alpha

• Signed written informed consent

Exclusion criteria

• Patients with Crohn's Disease

• Diagnosis of indeterminate colitis

• Patients with stool sample positive for ova, parasites, or positive culture for aerobic pathogens including: Aeromonas, Plesiomonas, Shigella, Yersinia, Campylobacter and E. Coli spp. or positive for Clostridium difficile B toxin in stools.

• Patients with prior colectomy or anticipated colectomy during their participation in the study

• Presence of ileal pouch or ostomy

• Fulminant disease or toxic megacolon

• Colonic dysplasia except for adenoma

• Total Parenteral Nutrition

• Cyclosporine, mycophenolate mofetil, sirolimus (rapamycin), thalidomide or tacrolimus within 2 months prior to screening

• Previous exposure to natalizumab (Tysabri®) or vedolizumab

• Antidiarrheals within 2 weeks prior to screening

• Prednisone >40 mg/day (or equivalent)

• Budesonide >9 mg/day

• Received intravenous corticosteroids within 2 weeks prior to screening or during screening

• Rectally administered topical 5-aminosalicylate or corticosteroids within 4 weeks prior to screening

• Received therapeutic enema or suppository, other than required for colonoscopy or flexible sigmoidoscopy within 4 weeks prior to screening or during screening

• Antibiotics for ulcerative colitis or gastrointestinal infection within 4 weeks prior to screening

• Patient who has previously participated in any clinical trial of GBR500 / SAR339658

• Patient who has taken other investigational medications within 2 months or 5 half lives, (whichever is longer) prior to screening

• Use of any biologics for the treatment of ulcerative colitis in the previous 8 weeks before screening

• Requirement for concomitant treatment that could bias primary evaluation

• Pregnant or breast-feeding women

• Women of childbearing potential not protected by highly effective contraceptive method of birth control

• Patient with latent or active tuberculosis (TB) defined as:

  • Any signs or symptoms suggestive of active TB upon medical history or clinical examination
  • Patients with a positive QuantiFERON TB Gold Test
  • Chest radiograph within 3 months prior to the inclusion visit consistent with prior tuberculosis infection including, but not limited to, apical scarring, apical fibrosis, or multiple calcified granulomasa. This does not include non-caseating granulomasa
  • Patients with close contact with a person with active tuberculosis

• Patient with a history of listeriosis or tuberculosis (unless it is documented that they were adequately treated)

• Administration of any live (attenuated) vaccine within 3 months prior to the screening Visit (eg, varicella-zoster vaccine, oral polio, rabies)

• Positive Hepatitis B surface antigen (HBsAg) or positive Hepatitis B core antibody (HBcAb); and/or positive Hepatitis C antibody (HCV) at the Screening Visit

• Prior opportunistic infections within 6 months prior to screening or while receiving anti-TNF treatment

• History of a hypersensitivity reaction, other than localized injection site reaction, to any biological molecule

• History or any current signs of demyelinating disease or any neurological disease that can by the opinion of Investigator interfere with study safety assessments including assessment for progressive multifocal leukoencephalopathy

• Patients with bleeding disorders or known platelet dysfunction
