Clinical Trial Summary
The purpose of this research study is to investigate the effects of an investigational
medication, called CCX282-B, on safety and on the some of the symptoms of Crohn's Disease in
patients who are experiencing an active flare-up of moderate to severe Crohn's Disease.
Description:
CCX282-B is being developed as a treatment for inflammatory bowel diseases such as Crohn's
Disease. CCX282-B is a highly potent, orally active, chemokine receptor antagonist whose
single target is the G-protein coupled receptor CCR9. The CCR9 receptor is expressed by most
T-cells in the thymus as well as in the intestine, and by a small population of T-cells in
the peripheral blood. In humans, the CCR9 receptor is implicated in Crohn's Disease and
ulcerative colitis.
Crohn's Disease is an autoimmune disease involving the entire length of the gastrointestinal
tract, but with most manifestations in the terminal small intestine and colon. This condition
is characterized by mucosal ulcerations that penetrate deeply into the bowel wall. Sometimes
the ulcerative lesions completely penetrate the bowel wall, leading to fistula formation and
infectious complications requiring surgical intervention. Patients experience considerable
lifestyle disruption and disability from this disease, including diarrhea, abdominal pain,
malnutrition, anemia, and repetitive surgeries to remove disease-affected gastrointestinal
segments.
ChemoCentryx Protocol CL003_282 is a double-blind, placebo-controlled, parallel group, two
stratum, Phase 2A pilot study of the safety, tolerability, immunologic and clinical activity,
and population pharmacokinetics of a single dose level of CCX282-B administered daily for
four consecutive weeks to patients with active, moderate to severe Crohn's Disease. The
primary immunologic and clinical activity objective of this study is to provide pilot
information regarding the immunologic and clinical activity of daily oral doses of CCX282-B
in the treatment of moderate to severe Crohn's Disease, based on changes in the Crohn's
Disease Activity Index (CDAI). Secondary immunologic and clinical activity objectives include
evaluation of the effect of CCX282-B on the Inflammatory Bowel Disease Questionnaire (IBDQ)
instrument, C-reactive protein (CRP), the endoscopic appearance and biopsy of the colon and
terminal ileum, and markers of leukocyte subsets and activation status. The primary safety
objective of this study is to evaluate the safety and tolerability of oral doses of CCX282-B
in patients with moderate to severe Crohn's Disease. In addition, blood samples will be
collected for evaluation of the population pharmacokinetics of CCX282-B.
