Lattice Study for Crohn’s Disease (LATTICE-CD): A Phase 2 Randomized, Double-Blind, Placebo- Controlled Study of the Safety and Efficacy of BMS 986165 in Participants with Moderate to Severe Crohn's Disease

Study Description:

• The LATTICE-CD study is designed to evaluate the safety and effectiveness of BMS-986165, an oral investigational study drug, compared with placebo (an inactive substance) to see if it may reduce symptoms of moderate to severe CD.
• Participants will have a 3 out of 4 chance of receiving the active investigational drug at the start of the study.
• Treatment assignment is blinded, so that neither you nor your doctor will know if you are receiving active study drug or placebo.
• Participants who do not have an adequate response at Week 12 may be eligible to receive open- label BMS-986165, where you will know that you are receiving the active investigational drug.
• Participation in the blinded period of this study is expected to last up to 52 weeks (1 year).
• Depending on your response and the study doctor’s recommendation, you may be eligible to receive active study drug for an additional 52 weeks (1 year) within this study.

Description of treatment or intervention (mechanism of action):

• In the LATTICE-CD study, doctors want to evaluate the investigational drug BMS-986165.
• They want to compare the investigational drug to placebo, which looks like the investigational drug, but contains no active medication.
• The investigational drug is thought to act on the body’s immune system to inhibit inflammation pathways that are thought to be important in Crohn’s disease.
• This study will evaluate if BMS-986165 is safe and effective in the treatment of Crohn’s disease.
• The patient will receive either placebo or the investigational drug.

Patient Participation Requirements:

If qualified, patients will be asked to:

• Attend all study visits (12 during the first 52 week treatment period).
• Take the oral investigational drug as directed.
• A variety of assessments such as lab tests, vital signs, physical exams, and endoscopies will be performed.
• Complete all questionnaires at study visits and maintain a daily electronic diary (to be provided) at home reporting details of Crohn’s disease, study dosing frequency, and any symptoms or side effects experienced.

Possible risks and side effects:

• BMS-986165 is still being studied, so not all of its potential side-effects are known.
• The most common side-effects seen in a recent Phase 2 clinical trial of BMS-986165 in psoriasis, a skin disease, included nose and throat irritation, headache, diarrhea, nausea and upper respiratory tract infection.
