Inclusion criteria

• 18-75 years at date of signing informed consent
• Male or female patients. Women of childbearing potential (WOCBP)1 must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. Restrictions regarding women of childbearing potential. Restrictions regarding contraception for female patients are not applicable for Screening Cohort
• Diagnosis of clinical Crohn´s Disease ≥ 3 months prior to screening by clinical and endoscopic evidence and corroborated by a histopathology report

• Has ≥ 1 perianal active* fistula(s) with clinical indication for seton drainage (≥ 4 weeks duration before enrolment, as a complication of CD) **

  * Criteria for Active Fistula: As per clinical evaluation: Presence of spontaneous drainage or drainage after gentle finger compression at the external openings & as confirmed by radiological (MRI) exploration

  ** Patients who are screened with a seton drainage in place are eligible provided the drainage has not been in place for > 3 months and the patient meets the rest of the eligibility criteria

• Absent, mild or moderate clinical activity with CDAI < 250. CDAI is not applicable for Screening Cohort
• Demonstrated in the past inadequate fistula response or loss of response or have had unacceptable side effects with approved doses of at least one of the following compounds: Immunesuppressive agents (e.g. thiopurines, methotrexate), TNFɑ antagonists (e.g. infliximab, adalimumab, certolizumab pegol; or respective biosimilars), vedolizumab, ustekinumab, azathioprine and / or antibiotics
• Patients with family history of colorectal cancer or personal history of increased colorectal cancer risk must have had a negative ileocolorectal cancer screening within <1 year prior to screening per local guidance
• Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial
• Further inclusion criteria apply

Gastrointestinal Exclusion Criteria (Study cohort only)

• Complications of Crohn's Disease such as symptomatic strictures, functional stenosis distal from fistula(s), short gut syndrome, or any other manifestation that might require surgery, could preclude the use of the PDAI and CDAI to assess response to therapy, or would possibly confound the evaluation of benefit from treatment with BI 655130
• Rectovaginal fistulas
• Anticipated to require surgical intervention for CD including any fistula surgical procedures (except seton drainage)
• Has an abscess that the investigator feels requires drainage beyond fistula drainage with a seton (based on either clinical assessment or MRI)
• Any kind of bowel resection or diversion within 6 months or any other intraabdominal surgery within 3 months prior to screening.
• Ileostomy, colostomy or known fixed symptomatic stenosis of the intestine at screening

• Positive stool examinations for C. difficile or other intestinal pathogens < 30 days prior to screening

  -- Evidence of colonic mucosal dysplasia or colonic adenomas, unless properly removed (properly according to the investigator's assessment)

• Faecal Microbiota transplant (FMT) within 6 months prior to randomization

• Treatment with:

  • any non-biologic medication (incl. cyclosporine, JAK inhibitors such as tofacitinib, tacrolimus, sirolimus, mycophenolate mofetile, S1P modulators, SMAD7 antisense inhibitors such as mongersen), other than those allowed per chapter 4.2.1 within 30 days prior to randomisation unless these patients show an undetectable plasma concentration
  • any biologic treatment approved for CD other than anti-TNFα inhibitors within 8 weeks prior to randomization unless these patients show an undetectable plasma concentration
  • any investigational or non-approved biologic for CD (including but not limited to IL-23 inhibitors) within 12 weeks prior to randomisation or etrolizumab within 8 weeks prior to randomization unless these patients show an undetectable plasma concentration
  • rectal 5-ASA, rectal Tacrolimus, parenteral or rectal corticosteroids (incl. budesonide) within 2 weeks prior to randomisation
  • any antibiotics within 1 week prior to randomisation
  • any prior autologous or allogeneic, haematopoietic (HSC) or mesenchymal stem cell (MSC) therapy
  • any prior exposure to BI 655130
  • any chronic use of NSAID within 2 weeks prior to randomisation (occasional use of NSAIDs and acetaminophen for headache, arthritis, myalgias, menstrual cramps, etc., and daily use of baby or low dose (81-162.5mg) aspirin for cardiovascular prophylaxis are permitted)
  • any life-attenuated vaccines within 6 weeks prior to randomization

Infectious Disease Exclusion Criteria (Study cohort only)

• Increased risk of infectious complications (e.g. due to past organ or stem cell transplantation)
• Live or attenuated vaccination within 6 weeks prior to randomization

• Patients with a positive QuantiFERON TB test during screening are excluded, unless:

  • Patient had previous diagnosis of active or latent TB and has completed appropriate treatment per local practice/guidelines within the last 3 years and at least 6 months before first administration of trial medication under this protocol (patients may be re-screened once to meet this criterion)
  • Patients with suspected false positive or indeterminate QuantiFERON TB result may be re-tested once
  • If Quantiferon not available or providing indeterminate results after repeat testing : A tuberculin skin test reaction ≥10mm (≥5mm if receiving ≥15mg/d prednisone or its equivalent)
• Relevant chronic or acute infections including active tuberculosis, human immunodeficiency virus (HIV) infection or viral hepatitis. A patient can be re-screened if the patient was treated and is cured from the acute infection.

General Exclusion Criteria (Study cohort only)

• Any documented active or suspected malignancy or history of malignancy within 5 years prior to screening, except appropriately treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ carcinoma of uterine cervix.
• Major surgery (major according to the investigator's assessment) performed within 12 weeks prior to randomization or planned during study conduct, e.g. hip replacement.
• Pathological safety lab parameters: haemoglobin < 8 g/dL, total white blood count (WBC) < 3000 cells/μl, neutrophils < 1000 cells/μl, thrombocytes < 100.000/μl, creatinine ≥ 2 mg/dL, total bilirubin > 2 x ULN with ratio of direct/indirect >1 (patients with Gilbert's syndrome are not excluded), Alkaline Phosphatase >3 x ULN.
• Patients who must or wish to continue the intake of restricted medications or any drug considered likely to interfere with the safe conduct of the trial

• Evidence of a current or previous disease, medical condition (including chronic alcohol or drug abuse) other than Crohn´s disease, surgical procedure, medical examination finding (including vital signs and electrocardiogram (ECG)), or laboratory value at the screening visit outside the reference range that in the opinion of the investigator is clinically significant and would make the study participant unreliable to adhere to the protocol or to complete the trial, compromise the safety of the patient, or compromise the quality of the data
• History of allergy/hypersensitivity to the systemically administered trial medication agent or its excipients or to contrast media
