Criteria
Inclusion Criteria:

1. Previous inclusion in the REScUE study and having reached the end of this study at
week 48.

2. Adequate contraception in females of reproductive age (oral, transdermal, injectable
contraception, intra-uterine device, sterilisation or barrier method). Adequate
contraception in males (sterilization or barrier method) if his female partner is of
reproductive age.

3. Have the capacity to understand and sign an informed consent form.

4. Be able to adhere to the study visit schedule and other protocol requirements.

Exclusion Criteria:

1. Patients previously enrolled to the ustekinumab 90 mg SC Q4w-arm during REScUE who
were on concomitant steroid use >20 mg prednisone equivalents (budesonide >6 mg;
beclomethasone dipropionaat >5 mg) at any time point in the last 28 days before the
end of REScUE at week 48.

2. Patients previously enrolled to the ustekinumab 90 mg SC Q4w-arm during REScUE that
did not reach the following criteria at the end of REScUE at week 48:

- Clinical remission (defined as average AP<=1 and average SF<=3) OR clinical
response (defined as a drop of at least 50% in average AP and/or a drop of at
least 50% in average SF as compared to REScUE baseline, and both average AP and
SF no worse than REScUE baseline) AND

- Endoscopic remission (defined as a total SES-CD <5) OR endoscopic response
(defined as a drop of at least 50% in total SES-CD score as compared to REScUE
baseline)

3. Patients who developed an anaphylactic or severe allergic reaction to study medication
during REScUE.

4. Patients with any of the following laboratory tests at W0 of the REScUE-OLE study :

- Hemoglobin level <8.5 g/dL

- Platelets level <100.000 /mm3

- Serum creatinine level ≥1.7 mg/dL

- AST and ALT level >3 times the upper limit of normal range

- Direct (conjugated) bilirubin level ≥3.0 mg/dL

5. Patients with an ongoing treatment with another concomitant biological (vedolizumab,
anti-TNF), a JAK-inhibitor or any investigational product for the treatment of Crohn's
disease at the end of REScUE at week 48.

6. Patients who experience or have an ongoing infection event confirmed by positive stool
or blood testing (including gastrointestinal pathogens, tuberculosis, HIV, hepatitis
B, hepatitis C) should not initiate REScUE-OLE until (i) this event has completely
resolved as shown by the termination of treatment with anti-infective medication, or
(ii) this event is considered to be in stable remission under anti-infective
medication in case of HIV, hepatitis B and hepatitis C.

7. Patients with an impassable stenosis even after attempt of endoscopic balloon
dilatation.

8. Patients with an intra-abdominal abscess, or patients with an intra-anal abscess
without adequate drainage by e.g. a seton placement.
