from Week 0 to Week 12

The variables platelet count, red blood cell (RBC) count, haemoglobin, haematocrit will be summarized with descriptive statistics

Number of participants with abnormal values in haematology: white blood cell (WBC) count
from Week 0 to Week 12

The variables neutrophils, lymphocytes, monocytes, eosinophils, and basophils will be summarized with descriptive statistics

CDAI remission
Week 12

Crohn's Disease Activity Index (CDAI) is a research tool used to quantify the symptoms of patients with Crohn's disease. It is based on: number of loose stools, abdominal pain, general well-being, extraintestinal complications, antidiarrheal agents used in the previous 7 days, abdominal mass felt on palpation, hematocrit and body weight

Change from baseline in intestinal SUV/SUVR
Weeks 13, 16, 20 and 24 (may vary between participants)

Standardized uptake value (SUV) is the radioactivity concentration in given region of interest normalized for injected radioactivity and body weight. Standardised uptake value ratio (SUVR) is the ratio of SUV in a given region of interest to a reference region without significant radioligand uptake

Percentage Change in Small Bowel Partition Coefficient (Kp) From Baseline (Positron Emission Tomography [PET]1 Visit) to PET2 Visit
PET1 visit (baseline; Day -7 to Day -1) and PET2 visit (Day 14 for all panels except Day 2 for Panel 3)

Kp is the partition coefficient that denotes radioactivity concentration ratio (area under the concentration-time curve \[AUC\] 0-60 min, intestines/AUC 0-60 min, blood). Kp denotes that denominator is the radioactivity measurement in blood (aorta), this is the reference region used in calculations. Percentage change in small bowel Kp from baseline (PET1 Visit) to PET2 visit is reported.

Percentage Change in Small Bowel Kp From Baseline (PET1 Visit) to PET3 Visit
PET1 visit (baseline; Day -7 to Day -1) and PET3 visit (Day 42 for all panels except Days 56 and 28 for Panels 2 and 6, respectively)

Kp is the partition coefficient that denotes radioactivity concentration ratio (area under the concentration-time curve \[AUC\] 0-60 min, intestines/AUC 0-60 min, blood). Kp denotes that denominator is the radioactivity measurement in blood (aorta), this is the reference region used in calculations. Percentage change in small bowel Kp from baseline (PET1 Visit) to PET3 visit is reported.

Number of participants with Adverse Events (AEs)
Until follow-up (Day 85) or Early termination (ET)

The safety and tolerability of AZD7798 following administration of single ascending doses will be assessed.
