3. The
characteristics of the study population.
A randomised, placebo-controlled, safety, tolerability, dose escalation,
pharmacokinetic study of various doses of subcutaneous SAL97 (anti-?4?1integrin)
will be conducted in 64 healthy male volunteers. We need healthy volunteers to
help us define the limits of ”normal”. Healthy volunteers can provide the
”cleanest” data. Using a patient can be difficult to separate the effects of
a study intervention from the effects caused by the disease or medications of
the patient. Healthy people can also tolerate adverse effects from the
experimental interventions more easily than patients can. The reason is because
drug toxicity can exacerbate the existing medical problems of patients (Dresser,

Subjects must
be aged between 18-55. The reason for choosing this age group is because people
can develop the disease at any age (Pietrangelo & Higuera, 2015). Due to safety
concerns, women are excluded from participation in this phase I trial. Lastly,
we do not make a distinction in ethnicity  (Travis, 2004).  

Group 1:              12 active + 4 placebo
Group 2:              12 active + 4
Group 3:              12 active + 4
Group 4:              12 active + 4

Inclusion Criteria:

Provided informed consent.

Subject is willing and able to remain in the study for the entire study
period and returns for an outpatient visit 7 days after study treatment

Vital signs of subject must be within the following ranges: heart rate:
40-100 beats per minute; systolic blood pressure: 90-145 mmHg; diastolic blood
pressure: 50-95 mmHg.

Exclusion Criteria:

interfered with the absorption, disposition, metabolism, or excretion of the study

Use of any medication in 2 weeks prior to study and
throughout study.

Treatment in any drugs that are inhibitors of cytochrome P450 (CYP) enzymes
within 30 days prior to study and that may have an impact on the safety of the
subjects and validity of the study results.

Unable to communicate or cooperate with the investigator.
