Plain English Summary

Background and study aims
Drug CCX507-B is being studied as a possible treatment for patients with inflammatory bowel diseases (IBD) such as ulcerative colitis (UC) or Crohn’s disease (CD). Patients with these diseases suffer considerable lifestyle disruption and disability due to their condition. As the disease progresses, it often leads to patients needing repeated surgeries to remove affected areas of the stomach and intestine. Therefore, a critical need for safe and effective non-surgical treatment of UC still remains.

Who can participate?
This study will include 30 healthy men and women aged 18-65.

What does the study involve?
The subjects will be randomly allocated to take CCX507-B or a placebo (sugar pill), administered orally. First, they will consume this pill once and later, they will consume this pill for a week. Participants will be followed up for 3 weeks.

What are the possible benefits and risks of participating?
Since this study mainly looks at the safety and tolerability of CCX507-B, there is likely no benefit for study subjects, other than the knowledge that they are potentially helping us understand how to use the medication in future studies. Safety risk is considered to be low, because CCX507-B has been tested safely in nonclinical studies.

Where is the study run from?
Pharmaceutical Research Associates Group B.V., Netherlands.

When is the study starting and how long is it expected to run for?
This study started in April 2014 and runs until June 20154.

Who is funding the study?
ChemoCentryx, Inc. (USA).

Condition

Inflammatory Bowel Diseases (IBD) such as ulcerative colitis (UC) or Crohn’s disease (CD)

Intervention

CCX507-B (30, 60 and 90 mg CCX507-B single dose and multiple doses for 7 days) or placebo. Period 1 involves subjects being randomized to CCX507-B or placebo and being dosed a single time. Period 2 involved subjects being randomized to CCX507-B or placebo and being dosed over a period of 7 days. After the conclusion of Period 2, subjects are followed for 3 weeks.

Phase

Phase I

Drug names

CCX507-B

Primary outcome measures

Safety and tolerability of CCX507-B. Safety is measured by adverse event, serum chemistry, urinalysis, and hematology assessments at Baseline, Days 2 and 4 after the single dose and Baseline, Days 2, 4, 8 and 15 of the multi-dose period.

Secondary outcome measures

Pharmacokinetic and pharmacodynamic profiles of CCX507-B. Pharmacokinetic profile is assessed on all study days, i.e., Days 1 through 4 of the single dose period and Days 1 through 15 of the multi-dose period. Pharmacodynamic markers are assessed at Baseline and on Days 1 and 2 of the single-dose period, and at Baseline and on Days 1, 2, 4, 5, 7, and 8 of the multi-dose period.
