Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 64 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

    2. MCS stool frequency (SF) subscore ≥1; AND
    3. MCS rectal bleeding (RB) subscore ≥1.

  4. Participants currently receiving the following SoC therapies for UC are eligible providing they have been on a stable dose for the designated period of time and are anticipated to be stable throughout the study:

    1. oral corticosteroids (prednisone ≤20 mg/day or equivalent or budesonide ≤3 mg/day) stable dose for at least 2 weeks prior to first investigational product (IP) dosing.
    2. oral 5-ASA compounds (mesalamine ≤4 grams [g]/day or sulfasalazine ≤4 g/day) stable dose for at least 4 weeks prior to first IP dosing.
    3. oral thiopurines (azathioprine ≤2.5 mg/kg/day and 6-mercaptopurine 1.5 mg/kilograms [kg]/day) stable dose for at least 12 weeks prior to first IP dosing, or methotrexate ≤20 mg/week, stable dose for at least 12 weeks prior to first IP dosing.

Key Exclusion Criteria:

  1. Diagnosis of Crohn's disease, indeterminate colitis, ischemic colitis, fulminant colitis, or toxic megacolon.
  2. Prior surgical intervention for UC (e.g. colectomy, partial colectomy, ileostomy or colostomy) or likely requirement for surgery for UC, during the study.
  3. History or evidence of incompletely resected colonic mucosal dysplasia.

  4. Exhibit acute severe UC per the following criteria:

    1. bloody diarrhea ≥6/day AND
    2. any of the following signs of systemic toxicity: Body temperature (oral or tympanic) ≥37.8 degrees celsius (°C) OR Resting pulse (after 5 min seated position) >90 beats per min OR hemoglobin <105 g/L, OR erythrocyte sedimentation rate >30 millimeters per hour (mm/h); OR C-reactive protein (CRP) >30 mg/L.

  6. Participant testing positive at screening for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection as detected by real time polymerase chain reaction (RT-PCR), participants presenting any signs or symptoms as detected at baseline following careful physical examination (e.g. cough, fever, headaches, fatigue, dyspnea, myalgia, anosmia, dysgeusia, anorexia, sore throat, others) or reporting any signs and symptoms for the preceding 2 weeks, or participants who have been exposed to individuals with confirmed or suspected diagnosis of SARS-CoV-2 within 2 weeks prior to baseline. In addition, any other locally applicable standard diagnostic criteria may also apply to rule out SARS-CoV-2 infection.

Note: Other protocol-defined Inclusion/Exclusion criteria may apply.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Total MCS at Week 6
Time Frame: Baseline and Week 6
The MCS is the primary tool for assessing ulcerative colitis activity. Total MCS is the sum of 4 subscores (i.e., stool frequency, rectal bleeding, endoscopic findings, and a physician's global assessment); each rated on a scale from 0 (normal) to 3 (severe). The total MCS value ranges from 0 to 12, with higher scores indicating more severe disease. Missing data were imputed using Rubin's multiple imputation.
Baseline and Week 6

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Time Frame: First dose date up to 14 days after the last dose of study drug (up to 57 days)

Treatment-Emergent Adverse Events (TEAEs) were defined as

  • Any adverse event (AE) with an onset date on or after the IP start date and no later than 14 days after last dose of IP, or worsening of any AE on or after the IP start date.
  • Improvement or no change of any ongoing AEs on or after the IP start date are not considered treatment-emergent. If an AE was ongoing at the time of first IP intake and if there was no change or an improvement in its toxicity grade or its seriousness status, this AE was not considered as treatment-emergent.

Serious TEAE was defined as a TEAE that

  • Resulted in death and was life-threatening;
  • Required in-patient hospitalization or prolongation of existing hospitalization;
  • Resulted in persistent or significant disability/incapacity;
  • Was a congenital anomaly / birth defect;
  • Was medically significant.
First dose date up to 14 days after the last dose of study drug (up to 57 days)
Plasma Concentration (Ctrough) of GLPG3970
Time Frame: Day 15: pre-dose; Day 29: pre-dose; Day 43: pre-dose
Ctrough was defined as plasma concentration level at the end of the dosing interval.
Day 15: pre-dose; Day 29: pre-dose; Day 43: pre-dose
