1.
Visit 1 of this LT extension study should preferably be performed in one visit combined with the last visit of the preceding trial 1311.6 or during the interim 
period of maximum 5 days after completion of the last visit in 1311.6. If an EoT colonoscopy has not been performed during E1 within 1311.6, it must be 
performed between V1 and V2 in 1311.20/M15-989.
2.
Assessments performed at the last visit in the previous trial do not have to be repeated at visit 1 in this trial.  Assessments scheduled but not performed at the 
last visit in the previous trial should be repeated at Visit 1 in this trial, and the results entered into the CRFs of both trials 1311.6 and 1311.20/M15-989.
3.
For patients who discontinue study medication before scheduled EoT visit, an early EoT visit should be performed.  After last dose of study medication, a 
140 day follow-up call should be scheduled. Upon EC/CA approvals of Study M16-000 protocol amendment 4, patients receiving treatment in M15-989 will 
have the option to enroll into M16-000 Sub-Study 3 after completing the EoT visit.
4.
Must be performed at Visit 1 and starting from Visit 2 prior to each study drug administration in females of childbearing potential. In case of positive result, 
serum pregnancy test will be performed. Study drug will only be administered if pregnancy is ruled out.
5.
Positive QuantiFERON-TB Gold In-Tube tests need not to be repeated. If TB or infection is suspected at any time during the study, a routine work up 
including chest x-ray and a QuantiFERON-TB Gold In-Tube test or an infection assessment must be performed at investigator's discretion and according to 
local guidelines. 
6.
Assessment of AE after subcutaneous injections will also include assessment of local tolerability.  The assessment of local tolerability should be done just 
before the patient leaves the investigator site.
7.
All assessments are to be completed prior to study drug administration, unless otherwise specified.
8.
An end of trial call should be performed for both patients that agree to enroll into M16-000 Sub-Study 3 OLE or those that do not choose to participate.
9.
For details of laboratory tests see Section 5.2.3, Table 5.2.3:1and Table 5.2.3:2.
10. Every effort should be made for the patient to perform a final ileocolonoscopy at the study visit where the last dose of study medication is administered.  For 
patients with early EoT, every effort should be made to perform a final ileocolonoscopy within 2 weeks following the early EoT visit.
11. Colonoscopy is not to be repeated if done at preceding visit.
12. IBDQ should be completed before site staff interaction and study drug administration.
13. Blood samples for PK and ADA will be drawn BEFORE drug administration, i.e. pre-dose, whenever visits coincide.
14. Visit 1.1 is applicable only for those patients that had visit E1 more than 5 days before Visit 1.  Visit 1.1 can be performed by phone, fax or email.
15. IRT has to be called only once at V1 or V1.1 after assessment if s.c or i.v. re-induction is needed.
16. In case patient had visit E1 less than 5 days before Visit 1, CDAI assessment and new patient diary dispense should be done at Visit 1.

1.
If an EoT colonoscopy has not been performed during E1/E5 within 1311.6, or if the patient had a treatment interruption followed by a clinical relapse, it 
must be performed between V1 and V2 in 1311.20/M15-989.
2.
Assessments performed at visit E1/E5 in the previous trial do not have to be repeated at Visit 1 in this trial.  Assessments scheduled but not performed at 
Visit E1/E5 in the previous trial should be repeated at visit 1 in this trial, and the results entered into the CRFs of both trials, 1311.6 and 1311.20/M15-989.
3.
For patients who discontinue study medication before scheduled EoT visit, an early EoT visit should be performed.  After last dose of study medication, a 
140 day follow-up call should be scheduled.  Upon EC/CA approvals of Study M16-000 protocol amendment 4, patients receiving treatment in M15-989 
will have the option to enroll into M16-000 Sub-Study 3 after completing the EoT visit.
4.
Must be performed at Visit 1 and starting from Visit 2 prior to each study drug administration in females of childbearing potential.  In case of positive result, 
serum pregnancy test will be performed.  Study drug will only be administered if pregnancy is ruled out.
5.
Positive QuantiFERON-TB Gold In-Tube tests need not to be repeated. If TB or infection is suspected at any time during the study, a routine work up 
including chest x-ray and a QuantiFERON-TB Gold In-Tube test or an infection assessment must be performed at investigator's discretion and according to 
local guidelines.
6.
Assessment of AE after intravenous infusions and subcutaneous injections will also include assessment of local tolerability. The assessment of local 
tolerability should be done just before the patient leaves the investigator site.
7.
All assessments are to be completed prior to study drug administration, unless otherwise specified.
8.
An end of trial call should be performed for both patients that agree to enroll into M16-000 Sub-Study 3 OLE or those that do not choose to participate.
9.
For details of laboratory tests see Section 5.2.3, Table 5.2.3:1 and Table 5.2.3:2.
10. Every effort should be made for the patient to perform a final ileocolonoscopy at the study visit where the last dose of study medication is administered.  For 
patients with early EoT, every effort should be made to perform a final ileocolonoscopy within 2 weeks following the early EoT visit.
11. Colonoscopy is not to be repeated if done at preceding visit.
12. IBDQ should be completed before site staff interaction and study drug administration.
13. Blood samples for PK and ADA will be drawn BEFORE drug administration, i.e. pre-dose, whenever the visits coincide.
14. Clinical response or remission will be compared to 1311.6 baseline (Visit 2), to continue SC medication patients should have response.
15. Visit can be performed by phone, fax or email.
16. IRT has to be called only once at V1 or V1.1 after assessment if s.c or i.v. re-induction is needed.

INTRODUCTION
1.1
MEDICAL BACKGROUND
Crohn's Disease (CD) is a chronic relapsing, remitting inflammatory disease of the 
gastrointestinal tract characterized by abdominal pain, fever, and bloody or mucus-
containing diarrhea (R13-2231). The disease affects the gastrointestinal tract 
discontinuously from mouth to anus, but most commonly the ileum and colon (40%), 
followed by the small bowel only (30%), and the colon only (25%) (R13-2232, 
R13-2233). It occurs in a relatively young population and there is no marked sex 
difference. 
The annual incidence of CD seems to be increasing with more recent estimates varying 
from 7.9 to 20.2 cases/100,000, and a prevalence of 161 to 319 cases/100,000 in North 
America and Europe (R13-2231). Mucosal lesions may be complicated by perforation and 
fistula formation, which may require hospitalization for medical or surgical management.
Because of myriad symptoms, clinical status is measured using clinical indexes. The most 
widely used, in clinical trials, is the Crohn's Disease Activity Index (CDAI) (R97-2689). 
At the mucosal level, the extent of disease can be graded following ileocolonoscopy 
according to the Crohn's Disease Endoscopic Index of Severity (CDEIS). 
Remission of clinical symptoms and endoscopic mucosal healing are predictors of long 
term improved clinical outcomes, including sustained steroid-free clinical remission, 
decreased need for surgical intervention, reduction in hospital admissions, improvement 
in quality of life, and increased work productivity (R13-2413). There is a poor correlation 
between CDAI and CDEIS. It has been reported that mucosal healing may be better than 
CDAI for the prediction of long term prognosis (R13-2295, R13-2294).
The mainstay of treatment of moderate to severe CD has been with glucocorticoid 
therapy, azathioprine, or 6-mercaptopurine (R13-2269). More recently, biologics 
consisting of monoclonal antibodies directed at cytokines, thought to mediate the 
pathology, have been used extensively for this indication. In clinical studies of infliximab, 
adalimumab, and certolizumab pegol, induction of CDAI remission at 4 weeks were in the 
range of 25 to 35% in contrast to placebo rates of 4 to 12%. At six months, response rates 
were of approximately 60% and remission rates of 40-50%, compared with 20% in 
placebo-treated patients. Adverse events reported with these agents include drug-induced 
lupus, lymphoma, demyelinating diseases, and serious and opportunistic infections, 
including tuberculosis and systemic fungal infections. Many patients lose response to 
TNF inhibitors over time, in part due to development of neutralizing or depleting anti-
drug antibodies (ADA). Overall, one third of patients fail to respond to initial anti-TNF

therapy (primary non-response), and another third lose their response over time 
(secondary non-response) (R13-2268, R13-2267, P13-05746, R13-2264, R13-2266, 
R13-2265). Thus, there remains a significant unmet medical need for better treatments of 
this disease.
BI 655066/ABBV-066 (risankizumab) is a humanized antibody that is directed against 
IL-23 p19. Although the etiology of Crohn's Disease (CD) is unknown, data suggest that 
there is altered immune regulation at the epithelial barrier, leading to overproduction of 
inflammatory cytokines, tissue destruction, and aberrant tissue repair. Among the 
cytokines implicated in CD pathogenesis, data at the genetic, human biology and clinical 
level strongly implicate IL-23 in this disease. In a Phase II placebo-controlled trial of the 
IL-12/IL-23 antagonist mAb ustekinumab in Crohn's Disease, 34.1 to 39.7% of patients 
receiving single doses of ustekinumab (1 mg/kg, 3 mg/kg, or 6 mg/kg) had a CDAI
response at 6 weeks, compared to 23.5% of patients receiving placebo (R12-5152). In a 
recent Phase II placebo-controlled trial of the specific IL-23p19 antagonistic mAb 
MEDI-2070 in moderate to severe Crohn's Disease, 46% of exclusively anti-TNF 
pretreated patients achieved a clinical response (vs. 25% on placebo) while 27% achieved 
a clinical remission (vs 15% on placebo) (R15-1973). Therefore, an IL-23 antagonist, 
whether directed against the p40 or p19 subunit, is likely to be an effective treatment for 
CD.

DRUG PROFILE
Preclinical summary
BI 655066/ABBV-066 (risankizumab) binds with high affinity to human and cynomolgus 
monkey IL-23, but it does not bind to rat or murine IL-23. There was no binding to IL-12 
at the highest concentration (100 nM) tested. Binding to human IL-23 was analyzed in the 
presence of 50% human serum to assess the potential for non-specific binding. BI 
655066/ABBV-066 (risankizumab) does not display interference to binding in the 
presence of 50% serum.
The primary functional cell assay for the IL-23 antibodies measures their ability to inhibit 
IL-23 stimulated IL-17 production from mononuclear cells isolated from mouse spleens.
Human, cynomologus, rat and mouse recombinant IL-23 are all capable of stimulating 
IL-17 release from mouse splenocytes with similar EC50 values. The ability of 
BI 655066/ABBV-066 (risankizumab)  to functionally inhibit both a recombinant and 
natural form of IL-23 was measured in this system. IC50 values for 

Risankizumab

EudraCT 2015-001834-15
33
BI 655066/ABBV-066 (risankizumab) were equivalently low against recombinant (6 pM) 
and naturally occurring (1 pM) forms of human IL-23 and lower than the IC50 observed 
with ustekinumab of 167 pM.
BI 655066/ABBV-066 (risankizumab) did not affect IL-12 at a maximum concentration tested 
of 33 nM and it did not inhibit IL-12 stimulated IFN-γ production, in contrast to a control 
antibody against IL-12 p70 that completely inhibited IFN-γ output.
A mouse ear inflammation model (R11-1273) of in vivo efficacy of 
BI 655066/ABBV-066 (risankizumab)  demonstrated 71% inhibition of ear skin 
thickness, 100% inhibition of ear tissue IL-17 and 94% inhibition of ear tissue IL-22 after 
1 mg/kg of BI 655066/ABBV-066. When ustekinumab was studied in the same model, 
similar levels of inhibition in IL-17 and IL-22 levels were seen at a dose of 1 mg/kg of 
ustekinumab as with 0.1 mg/kg of BI 655066/ABBV-066. These results suggest that 
BI 655066/ABBV-066 (risankizumab) may have higher potency than ustekinumab.
Toxicology summary
No adverse findings have been identified in any of the toxicology studies using 
BI 655066/ABBV-066 (risankizumab).
In the 26 week monkey toxicity study, marginal but transient test article-related decreases 
in B lymphocytes were noted only at Month 1 in ≥5mg/kg/week animals (both sexes), but 
this change was not noted at 3 or 6 month time points.  Given the small magnitude of 
change and the transient nature of the decrease in B lymphocytes, this is not considered an 
adverse change.  Also in the 26 week study, hypospermatogenesis was observed at a low 
incidence in the testes of ≥ 5 mg/kg/week males and correlated with a reduction in testes 
weights only in 50 mg/kg/week males. Following 8 weeks of recovery, there was no 
testicular pathology or testis weight effect in 50 mg/kg/week males.  The 
hypospermatogenesis was not considered as an adverse event given the small magnitude 
of change and no corresponding decrease of epididymal sperm. In contrast, an external 
expert panel interpreted these findings as normal variations associated with the onset of 
puberty that were not considered to represent testicular toxicity related to treatment with 
BI 655066/ABBV-066 (risankizumab). Moreover, a repeat 26 week male fertility study in 
sexually mature monkeys demonstrated that weekly subcutaneous administration of BI 
655066/ABBV-066 (risankizumab) at 50 mg/kg/week for 26 weeks to sexually mature 
male cyno monkeys produced no BI 655066/ABBV-066 (risankizumab) related effects on 
reproductive parameters. 
The toxicology data suggest BI 655066/ABBV-066 (risankizumab) can be safely 
administered to humans, as supported by chronic administration to monkeys for up to 

Risankizumab

26 weeks. The monkey was identified as the most relevant toxicology species with a 
NOAEL of 50 mg/kg/dose, corresponding to an exposure (combined sex) of 677 μg/mL 
for the Cmax and 86,250 μg.h/mL for AUC0-168, respectively.
Clinical summary
BI 655066/ABBV-066 (risankizumab) has been studied in a randomized, double blind, 
single dose trial in a total of 39 patients with moderate to severe psoriasis (Study 1311.1). 
BI 655066/ABBV-066 (risankizumab) was administered i.v. in ascending doses ranging 
0.01 mg/kg to 5 mg/kg i.v., or s.c. in doses of 0.25 mg/kg or 1 mg/kg. After a single i.v. 
administration, exposure (Cmax and AUC) to BI 655066/ABBV-066 (risankizumab)
increased with dose in an approximately dose-proportional manner. The variability and 
the estimates of the pharmacokinetic parameters after i.v. dosing of BI 655066/ABBV-
066 (risankizumab)  appears to be in line with other mAbs binding a soluble target. The 
geometric mean half-life of BI 655066/ABBV-066 (risankizumab) ranged from 
approximately 20-28 days. The Tmax occurred at approximately 1 to 2 h from start of i.v. 
infusion in all patients given BI 655066/ABBV-066 (risankizumab).
Mean Psoriasis Area and Severity Index (PASI) scores showed no relevant change over 
time among placebo treated patients, but showed marked improvements among the 
BI 655066/ABBV-066 (risankizumab) treatment groups in Study 1311.1. At doses of 
0.25 mg/kg and above, all dose groups showed improvement in mean PASI scores of at 
least 75% from baseline by week 12, which lasted at least until week 20. Similar 
improvements were observed in both of the BI 655066/ABBV-066 (risankizumab) 
subcutaneous dose groups.
In a subsequent randomized double-dummy design phase IIb trial, 166 patients with 
moderate or severe plaque psoriasis were randomly assigned to one of three dose 
regimens of BI 655066/ABBV-066 (risankizumab)  (18/0, 90/90 or 180/180 mg s.c. at 
weeks 0 and 4) or ustekinumab (45 or 90 mg, per weight, s.c. at weeks 0 and 4). The 
primary endpoint was PASI 90 at week 12, comparing BI 655066/ABBV-066 
(risankizumab) with ustekinumab. In the pre-specified primary analysis of the 90 and 
180 mg BI 655066/ABBV-066 (risankizumab) doses (pooled), BI 655066/ABBV-066 
(risankizumab) was superior to ustekinumab (PASI 90 77.1% for BI 655066/ABBV-066 
(risankizumab) vs 40.0% for ustekinumab [p<0.0001]). Ninety percent of BI 
655066/ABBV-066 (risankizumab) patients had sPGA of clear or almost clear compared 
with 67.5% for ustekinumab. Forty-six percent of BI 655066/ABBV-066 (risankizumab)
patients had complete clearing of lesions (PASI 100) compared with 17.5% for 
ustekinumab. AEs were similar across treatment groups with no drug-related severe or 
serious AEs. Thus, selective blockade of IL-23p19 with BI 655066/ABBV-066

EudraCT 2015-001834-15
35
(risankizumab) was associated with clinical responses superior to ustekinumab in patients 
with moderate-to-severe plaque psoriasis.
The overall safety profile of risankizumab is consistent with its mechanism of action. 
Across all indications and doses, the most frequently reported AEs (AEs or serious AEs 
that received at least 1 dose of risankizumab) were nasopharyngitis, upper respiratory tract 
infection, headache, and arthralgia. Based on the review of all the risankizumab safety 
data to date, there are no important identified risks.

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
The etiology of CD is unknown but data suggests altered immune regulation at the 
epithelial barrier leading to overproduction of inflammatory cytokines, tissue destruction 
and aberrant tissue repair (R13-2231). 
Biologic agents targeting TNFα, a cytokine thought to mediate the pathology of CD, have 
been used extensively for this indication. However, one-third of patients do not respond to 
anti-TNF agents, and another third of patients have only a transient response (R13-2268, 
R13-2267, P13-05746, R13-2264, R13-2266, R13-2265). There remains a high unmet 
medical need for effective therapies for CD, particularly with a different mode of action 
that overcomes current treatment limitations.
Among the cytokines involved in CD pathogenesis, data at the genetic, human biology 
and clinical level strongly suggests the role of IL-23 in this disease (R13-2625;
R12-5152). Analysis of tissue obtained from surgical biopsies or endoscopies has shown 
that IL-23 and IL-23R are upregulated in the inflamed mucosa of CD (R12-1009). Data 
from T cell-driven murine models of colitis support the role of IL-23 in gut pathology 
(R11-1269; R11-1271). Ustekinumab, an IL-12/IL-23 p40 antagonist mAb, has shown 
clinical efficacy in Phase II studies of CD (R12-5152). Furthermore, the IL-23 p19 
antibody MEDI-2070 has shown very promising activity in patients with CD who have 
failed one or more anti-TNF treatments before (R15-1973). Finally, BI 655066/ABBV-
066 (risankizumab) has shown superior clinical efficacy with comparable safety 
compared to ustekinumab in a phase II trial in chronic plaque psoriasis, another disease 
associated with dysregulation of the IL-23 pathway (P15-03262).
Together, these observations suggest that BI 655066/ABBV-066 (risankizumab) may
demonstrate efficacy in this disease.
2.2
TRIAL OBJECTIVES
The purpose of this long term safety extension trial is to provide subjects who responded 
to treatment with BI 655066/ABBV-066 (risankizumab) in a preceding trial with a 
long-term treatment option.

Risankizumab
1311.20/M15-989 Protocol Amendment 4
EudraCT 2015-001834-15
37
The primary objective of the study is to investigate long-term safety of 
BI 655066/ABBV-066 (risankizumab), in patients with moderately to severely active 
Crohn`s disease, who showed a clinical response or remission on previous treatment with 
BI 655066/ABBV-066 (risankizumab) and are now receiving long term treatment.
Additional objectives of this study are to further investigate long-term efficacy, 
tolerability, pharmacokinetics, pharmacodynamics and immunogenicity of 
BI 655066/ABBV-066 (risankizumab).
Study endpoints are listed in Section 5.1.1.
2.3
BENEFIT - RISK ASSESSMENT
The preclinical and clinical profiles of BI 655066/ABBV-066 (risankizumab) suggest that 
it profoundly inhibits IL-23 in patients with psoriasis and thus has the potential to address 
unmet medical need in Crohn's disease, as shown for other IL23 inhibitors before (see 
Section 1.2) (R15-1973). Since Crohn's disease is a chronic disease that typically requires 
long-term treatment, a direct benefit for the individual participants in this study can be 
assumed, since only such patients will be enrolled that have achieved a clinical response 
to this compound in the preceding trial 1311.6.
In addition, participation in this study may help to generate a group benefit by providing a 
new treatment modality for the population of patients with moderate or severe Crohn's 
disease if BI 655066/ABBV-066 (risankizumab) proves to be successful in treating this 
disease.
Though there are no serious adverse drug reactions known to be associated with 
risankizumab therapy, risks of participating in this study include risk of infection and risks 
related to the trial specific procedures blood sampling, infusion and injection of study 
medication, and ileocolonoscopy.
Blood sampling, intravenous infusions and subcutaneous injections can cause local 
bruising, inflammation, and pain. Ileocolonoscopy although generally well tolerated, can 
be associated with diarrhoea, abdominal pain, perforation, bleeding, effects from 
anaesthetic medications and infection.
As with any immune modulating agent, BI 655066/ABBV-066 (risankizumab) has the 
potential to impair immune function resulting in an increased risk of infections. This will 
be addressed by clinical monitoring for AEs during the treatment and observation periods.

Interferon gamma (IFN-γ) release assay to M. tuberculosis will be obtained at visit 1, to 
exclude or discontinue patients with untreated active or latent TB infection. All patients 
with negative TB screening at baseline will be re-tested once per year in order to exclude 
possible active or latent TB infection. Patients having current signs or symptoms of 
infection or history of serious infection will not be included in the study.
Major adverse cardiovascular events, including myocardial infarction, cerebrovascular 
accident, and cardiovascular death, have been reported in patients with Psoriasis treated 
with the anti-IL-12/23 agents, ustekinumab and briakinumab, based on their frequent co-
morbidities associated with cardiovascular risk. Such an association has not been reported 
in other diseases and the causal relationship of MACE to treatment with these agents is 
unclear. The overall risk of MACE in the present study is considered to be low. However, 
all suspected cardio- and cerebro-vascular events (serious or nonserious) observed in this 
study will be adjudicated by an independent cardiovascular adjudication committee 
(CAC) during long-term treatment.
Local reactions to s.c. administered biologic agents are uncommon, and are usually 
limited to redness, swelling or induration at the injection site. Manifestations of systemic 
infusion reactions include anaphylaxis, pruritus, hypotension, and respiratory distress. 
Both local and systemic hypersensitivity reactions were rare in phase II, readily 
detectable, transient in nature, and manageable with standard medical treatment. No 
systemic hypersensitivity reactions have been reported with BI 655066/ABBV-066 
(risankizumab) to date. Patients will be closely monitored for at least 2 to 3 hours after 
start of i.v. drug administration whereas 30 minutes to 1 hour after s.c. drug 
administration for signs of redness, swelling or hardness at the injection site or 
generalized itching, dizziness or difficulty breathing.
The role of IL-23 in tumor immunity is not well established at this time, but an increased 
risk of cancer from an IL-23 antagonist, though considered small, cannot be excluded.
Although rare, a potential for drug-induced liver injury is under constant surveillance by 
sponsors and regulators. Therefore, this study requires timely detection, evaluation, and 
follow-up of laboratory alterations of selected liver laboratory parameters to ensure 
patients' safety.
Summary of benefit-risk assessment
The benefit-risk profile is considered appropriate for an experimental therapy at this stage 
of clinical development. In order to mitigate any safety signals as early as possible, an 
independent DMC will oversee this study.

The independent external CAC will be adjudicating observed cardio- and cerebro-vascular 
events.  The events that are adjudicated and the adjudication process will be detailed in 
the Cardiovascular Adjudication Committee Charter. Dedicated eCRFs will be used for 
events of myocardial infarction-unstable angina, stroke-transient ischemic attack, and 
death. In addition, the site may be contacted for additional source documentation for

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This open label long term extension trial investigates the long term safety and efficacy of 
BI 655066/ABBV-066 (risankizumab). Approximately 60 patients who meet the entry 
criteria are planned for inclusion in this trial, rolling over from preceding trial 1311.6. The 
treatment will be open label.
The treatment period will be 204 (Flow chart 1), 206 (Flow chart 2) or 216 (Flow chart 3) 
weeks, followed by a 140 day follow up period.
Patients rolling over from preceding trial 1311.6 will have to complete period 2 or 3 in 
that trial and either demonstrate a clinical response without remission at Visit E1 or a 
clinical response or remission at Visit E5 as defined by that protocol (see Figure 3.1:1).
Figure 3.1:1
Guideline for roll over of patients from 1311.6 to long term extension 
study 1311.20/M15-989
All patients directly rolled over from 1311.6 into 1311.20/M15-989 will receive 180 mg 
BI 655066/ABBV-066 (risankizumab) subcutaneously from visit 2 onwards every

8 weeks, until the EoT visit is performed. Patients who complete this study may elect to 
continue in M16-000 Sub-Study 3 (Phase 3 open label extension study).
Patients who have completed 1311.6 qualifying for roll-over into 1311.20/M15-989 
before availability of this study, can be enrolled depending on their clinical remission or 
response. If patients were treated between finishing 1311.6 and entering 
1311.20/M15-989 with anti-TNF therapy or any biologic agent an 8 weeks or 5 times the 
half-life (whichever is longer), wash-out period will be needed before administration of 
first i.v or s.c. study medication. Patients must maintain their best response status (clinical 
response or remission) post 1311.6. Patients who dropped from 1311.6 with remission 
must maintain remission or undergo re-induction while responders will have to maintain 
their response.
!
If clinical response or remission (CDAI drop >100 from baseline of 1311.6 or 
CDAI < 150) was maintained after end of treatment and is confirmed at screening for 
1311.20/M15-989, patients can directly be assigned to open label s.c. maintenance 
treatment with 180 mg every 8 weeks (FLOW CHART 1) ( visit window between last 
IMP dose in 1311.6 and first IMP dose in 1311.20/M15-989 should be at least 
8 weeks).
!
If clinical remission (achieved at E5 1311.6) has been lost after end of treatment in 
1311.6 and/or at screening for 1311.20/M15-989, patients will receive open label i.v. 
re-induction treatment with three infusions of 600 mg each every 4 weeks after which 
eligibility will be re-assessed. If clinical remission or at least response compared to 
1311.6 study baseline (V2) is achieved patients will switch to s.c. maintenance 
treatment with 180 mg s.c. every 8 weeks (Flow chart 3), otherwise an EoT visit has 
to be performed. After last administration of trial drug in 1311.20/M15-989 trial, a 
140 day follow up call should be scheduled for patients who do not elect to enroll in 
Study M16-000.
!
If clinical response (achieved at E1 or E5 1311.6) has been lost after end of treatment 
in 1311.6 and/or at screening for 1311.20/M15-989, patients will receive open label 
i.v. re-induction treatment with three infusions of 600 mg each every 4 weeks after 
which eligibility will be re-assessed. If clinical response or remission compared to 
1311.6 study baseline (V2 1311.6) is achieved patients will switch to s.c. maintenance 
treatment with 180 mg s.c. every 8 weeks (Flow chart 3), otherwise an EoT visit has 
to be performed. After last administration of trial drug in 1311.20/M15-989 trial, a 
140 day follow up call should be scheduled for patients who do not elect to enroll in 
Study M16-000.
The results from the last colonoscopy done in 1311.6 will serve as baseline for 
1311.20/M15-989. A colonoscopy at screening is only required for patients who lost

response or remission during extended follow-up phase after completion of 1311.6. 
Colonoscopies are repeated once per year to assess the effect of continued treatment on 
endoscopic response and mucosal healing.
The end of study is defined as the date the last subject completes the End of trial visit
The primary analysis will be performed after all patients have completed their EoT visit. 
The reference values for the efficacy endpoints clinical or endoscopic response will be the

3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP(S)
Study 1311.20/M15-989 is designed as an open label, single group trial and is expected to 
generate long term safety information to support the submission for registration. As noted 
in Section 4.1.3 below, the s.c. dose (180 mg every 8 weeks) from the study 1311.6 will 
be used in all patients for the maintenance treatment. Since study 1311.6 has not been 
completed and analysed at the time this study has been designed, the highest induction 
schedule of three 600 mg infusions every 4 weeks that was found safe in 1311.6 will serve 
as re-induction dose for patients who lost their response or remission between completion 
of 1311.6 and enrolment in 1311.20/M15-989. 

Risankizumab
1311.20/M15-989 Protocol Amendment 4
EudraCT 2015-001834-15
44
The goal of this study is to obtain initial on-drug, long-term safety data together with early 
evidence on the durability of the clinical response, that both will be essential for the 
licensing authorization application. As typical for an open-label, single-group study, 
neither powered nor controlled analyses can be obtained. However, the study may yield 
initial tendencies and at the same time permit early study participants to continue a 
successful therapy.
3.3
SELECTION OF TRIAL POPULATION
Eligible patients from preceding 1311.6 trial will be offered participation in this long term 
extension trial based on their achievement of clinical response. The check for patient
eligibility will be based upon a successful treatment (Section 3.3.2) of the preceding trial 
and on signing the Informed Consent for the long term extension trial.
Based on the results for the MEDI-2070 compound with identical mode-of-action, it is 
expected that up to 50 % of patients in 1311.6 will achieve a clinical response after 
induction treatment. Assuming a 100% maintenance rate of their response, up to 
60 patients may be entered in this trial.

3.3.4
Removal of patients from therapy or assessments
3.3.4.1
Removal of individual patients
An excessive rate of withdrawals may render the study results uninterpretable; therefore 
unnecessary withdrawal of patients must be avoided. Patients who discontinue their 
treatment early should undergo all study required procedures including an early EoT visit 
and colonoscopy, as defined in Section 6.
Patients have the right to withdraw from the study at any time without the need to justify 
the decision.
The sponsor reserves the right to terminate a patient from the trial for non-compliance.
The investigator has the right to remove patients from the study for non-compliance.
Furthermore, patients' treatment must be discontinued early due to lack of efficacy 
(defined as an endoscopically confirmed CDAI re-increase to >100 points above baseline 
in 1311.6 and a CDEIS >4), or for other reasons (as described below). If, in the 
investigator's opinion, such a patient requires alternative medical therapy for their Crohn's 
disease, the study treatment must be stopped and patients may receive conventional 
treatment for active disease as per investigator's judgment.
Criteria and rules for stopping patient treatment due to reasons other than lack of efficacy 
include:
!
Development of a toxicity or adverse event which warrants drug discontinuation.
!
Development of any potentially life-threatening toxicity.
!
Any concomitant illness that prevents compliance.
!
The patient is unwilling to continue in the trial.

!
Pregnancy in a female participant.
!
Patient lost to follow-up despite reasonable efforts to make contact with the patient.
!
Patient is no longer able to participate for other medical reasons (e.g., surgery, adverse 
events or other diseases).
!
The DMC may recommend termination or re-design of the trial for other relevant 
issues of safety.
Patients who discontinue from the study after Visit 2 will be considered as "early 
discontinuations" and the reason for premature discontinuation must be recorded in the 
eCRFs. The data will be included in the trial database and will be reported. 
3.3.4.2
Discontinuation of the trial by the sponsor
Abbvie Inc., reserves the right to discontinue the trial overall or at a particular trial site at 
any time for the following reasons:
1. Failure to meet expected enrolment goals overall or at a particular trial site,
2. Emergence of any efficacy/safety information that could significantly affect 
continuation of the trial, or any other administrative reasons, i.e. termination of 
clinical development of BI655066 in Crohn's disease,
3. Violation of GCP, the CTP, or the contract by a trial site or investigator, disturbing the 
appropriate conduct of the trial.
The investigator / the trial site will be reimbursed for reasonable expenses incurred in case 
of trial termination (except in case of the third reason).

4.1.3
Selection of doses in the trial
Direct roll-over patients from 1311.6 will receive open label treatment with 180 mg s.c. 
q8w, representing the maintenance dose tested in phase II, that was found safe and 
effective in preceding study 1311.6.
Early completers of 1311.6 dependent on clinical response post study treatment and at 
screening in 1311.20/M15-989 will receive either 180 mg s.c. q8w maintenance treatment 
or re-induction with 3 infusions of 600 mg i.v. q4w followed by180 mg s.c. q8w 
maintenance treatment.
4.1.4
Drug assignment and administration of doses for each patient
The dose of BI 655066/ABBV-066 (risankizumab) for s.c. and i.v. injections will be fixed.
The subcutaneous study drug will be administered as an injection in the abdomen, thighs, 
gluteal region, or upper arms. Injections being given in the same area should be at least 
2 cm apart and should not be close to a vein. The injection site should avoid sites where 
the skin is tender, bruised, erythematous, or indurated, and should be alternated to other 
areas for subsequent doses.
Supplied BI 655066/ABBV-066 (risankizumab) solution for i.v. administration 
(concentration 10.0 mg/mL) will be injected into a 100 mL i.v. infusion bag of 5% 
dextrose in water (D5W) and administered as described in detail in the Investigator Site 
File (Instructions for Preparation and Handling of BI 655066/ABBV-066 (risankizumab)).
Subcutaneous administration of biologic agents involves the risk of local (injection site) 
or systemic hypersensitivity reactions. Therefore patients should be closely monitored for 
signs and symptoms of hypersensitivity reactions for approximately 30 minutes following 
study drug administration. Study personnel should observe the injection site for signs of 
redness, swelling or hardness. They should also ask subjects about itching, dizziness or 
shortness of breath. Patients should be advised that if they experience redness, swelling or 
other changes at the injection site, they should notify site personnel. They should further 
be advised that if they experience itching all over or a feeling of being swollen, dizzy or 
short of breath, they should notify site personnel or their own healthcare provider 
immediately.
The i.v. study drug will be administered under immediate supervision of the physician 
investigator or a designee with a minimum of a nursing degree. In all cases a physician 

Risankizumab

5.1.2
Assessment of efficacy
CDAI, PRO-2
The investigator will determine and record the CDAI score throughout the study, as 
denoted (see Flow chart 1, Flow chart 2 and Flow chart 3). Hematocrit evaluations will be 
made at each visit by the central laboratory as they are integral to the CDAI calculation.
The Patient reported outcome-2 (PRO-2) includes only the two CDAI items stool 
frequency and abdominal pain and will be analyzed based on the CDAI responses 
recorded by the investigator for these two dimensions.
Inflammatory Bowel Disease Questionnaire (IBDQ)
The IBDQ (R97-3472) is a 32-item self-report questionnaire for patients with IBD to 
evaluate the patient reported outcomes across 4 dimensions: bowel symptoms (loose 
stools, abdominal pain), systemic symptoms (fatigue, altered sleep pattern), social 
function (work attendance, need to cancel social events), and emotional function (anger, 
depression, irritability). Scores range from 32 to 224 with higher scores indicating better 
outcomes.
The patient will complete the IBDQ before site staff interaction and study drug 
administration as noted in the Flow chart 1, Flow chart 2 and Flow chart 3.
Tapering of corticosteroids
Any change in the corticosteroid co-medication has to be recorded on the appropriate 
eCRF page for Crohn's disease specific co-medication. The dose of corticosteroid 
co-medication should remain stable prior to achieving clinical remission.
CRP and Fecal Calprotectin
Concentration of serum CRP and fecal calprotectin will be measured by the central 
laboratory, and if necessary by additional specialist laboratories.
Ileocolonoscopy, SES-CD and CDEIS
Every effort should be made for the patient to perform a final ileocolonoscopy at the study 
visit where the last dose of study medication is administered or within 2 weeks following 
the premature discontinuation visit.

Risankizumab
1311.20/M15-989 Protocol Amendment 4
EudraCT 2015-001834-15
60
Lesions detected by ileocolonoscopy will be scored by means of the validated Crohn's 
Disease Endoscopic Index of Severity (CDEIS). The same endoscopist at the study site 
will complete the CDEIS for each ileocolonoscopy immediately after the procedure. 
Investigators will record endoscopies and send the videos to the central imaging 
laboratory. A central reading of endoscopies will be performed by independent blinded 
reviewer(s) and the findings will be scored using both, the CDEIS and the SES-CD 
scores. In case of discrepancies between the local endoscopic and central blinded 
reviewer, the centrally read scores will be used for efficacy assessments and the trial 
report.
Fistula response
A fistula response is defined as a ≥ 50% reduction in the number of draining fistulas.
Enterocutaneous fistulas (e.g., perianal and abdominal) will be considered no longer 
draining (i.e., closed) when there is absence of drainage despite gentle compression. 
Rectovaginal fistulas will be considered closed based on either physical examination, 
appropriate MRI imaging or absence of relevant symptoms (e.g., passage of rectal 
material or flatus from the vagina).
5.2
SAFETY
5.2.1
Endpoint(s) of safety
There is no primary endpoint in a statistical sense in this study (see Section 7.2). Instead, 
safety and tolerability will be assessed in a descriptive way based on:
!
Physical examination
!
Vital signs (blood pressure (BP), heart rate (HR) and oral body temperature)
!
12-lead ECG (electrocardiogram)
!
Clinical laboratory tests (haematology, clinical chemistry and urinalysis)

5.2.2
Assessment of adverse events
5.2.2.1
Definitions of adverse events
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or 
clinical investigation subject administered a medicinal product and which does not 
necessarily have to have a causal relationship with this treatment.  An AE can therefore be 
any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom or disease temporally associate with the use of a medicinal (investigational) 
product, whether or not the event is considered causally related to the use of the product.
Such an event can result from use of the drug as stipulated in the protocol or labeling, as 
well as from accidental or intentional overdose, drug abuse, or drug withdrawal. Any 
worsening of a pre-existing condition or illness is considered an AE.  Laboratory 
abnormalities and changes in vital signs are considered to be AEs only if they result in 
discontinuation from the study drug, necessitate therapeutic medical intervention, and/or 
if the investigator considers them to be AEs.
An elective surgery/procedure scheduled to occur during a study will not be considered an 
adverse event if the surgery/procedure is being performed for a pre-existing condition and 
the surgery/procedure has been pre-planned prior to study entry.  However, if the 
pre-existing condition deteriorates unexpectedly during the study (e.g., surgery performed 
earlier than planned), then the deterioration of the condition for which the elective 
surgery/procedure is being done will be considered an adverse event.
Adverse reaction
An adverse reaction is defined as a response to a medicinal product which is noxious and 
unintended. Response in this context means that a causal relationship between a medicinal 
product and an adverse event is at least a reasonable possibility. Adverse reactions may 
arise from use of the product within or outside the terms of the marketing authorisation or 
from occupational exposure. Conditions of use outside the marketing authorization 
include off label use, overdose, misuse, abuse and medication errors.
Serious adverse event
A serious adverse event (SAE) is defined as any AE which results in death, is life-
threatening, results in persistent or significant disability  or incapacity, requires inpatient 
hospitalisation or prolongation of existing hospitalisation, is a congenital anomaly / birth 

Risankizumab
1311.20/M15-989 Protocol Amendment 4
EudraCT 2015-001834-15
62
defect, or is to be deemed serious for any other reason if it is an important medical event 
when based upon appropriate medical judgement which may jeopardise the patient and 
may require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions.
Medical and scientific judgment should be exercised in deciding whether other situations 
should be considered serious reactions, such as important medical events that might not be 
immediately life threatening or result in death or hospitalisation but might jeopardise the 
patient or might require intervention to prevent one of the other outcomes listed above.
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm, blood dyscrasias or convulsions that do not result in 
hospitalisation or development of dependency or abuse. Any suspected transmission via a 
medicinal product of an infectious agent is also considered a serious adverse reaction.
Life-threatening in this context refers to an event in which the patient was at risk of death 
at the time of the event; it does not refer to an event that hypothetically might have caused 
death if more severe.
Adverse Events of Special Interest (AESI)
The term AESI relates to any specific AE that has been identified at the project level as 
being of particular concern for prospective safety monitoring and safety assessment within 
this trial, e.g. the potential for AEs based on knowledge from other compounds in the 
same class. AESI need to be reported to the Sponsor's Pharmacovigilance Department 
within the same timeframe that applies to SAE, see Section 5.2.2.2.
The following are considered as AESI:
!
Hepatic injury defined by the following alterations of liver parameters:
o
For patients with normal liver function at baseline:
an elevation of aspartate aminotransferase (AST) and/or alanine 
aminotransferase (ALT) > 3 fold upper limit of normal (ULN) combined 
with an elevation of total bilirubin > 2 fold ULN measured in the same 
blood draw sample.
o
Hepatic injury defined by the following alterations of liver parameters (for 
patients with impaired liver function tests at baseline): an elevation of AST 
and/or ALT ≥ 3 times the baseline value combined with an elevation of 
bilirubin ≥ 2 times the baseline value measured in the same blood draw 
sample.

Risankizumab
1311.20/M15-989 Protocol Amendment 4
EudraCT 2015-001834-15
63
Patients showing these lab abnormalities need to be followed up according to 
Section 10.1.2 of this clinical trial protocol and the hepatic injury adverse event form 
provided via EDC system.  These lab findings constitute a hepatic injury alert and the 
patients showing these lab abnormalities need to be followed up according to the hepatic 
injury AE form via the EDC-system. In case of clinical symptoms of hepatic injury 
(icterus, unexplained encephalopathy, unexplained coagulopathy, right upper quadrant 
abdominal pain, etc.) without lab results (ALT, AST, total bilirubin) available, the 
investigator should make sure these parameters are analysed, if necessary in an 
unscheduled blood test.  Should the laboratory results meet the definition of hepatic 
injury, the investigator will complete the supplemental form.Cardiac Events/Procedures
In the case of any of the following reported major cardiovascular adverse events (MACE), 
the appropriate supplemental eCRFs should be completed:
●
Cardiac events;
●
Myocardial infarction or unstable angina;
●
Cerebral vascular accident and transient ischemic attack;
●
Cardiovascular procedures
Tuberculosis (TB)
In the case of any positive TB test or diagnosis of active TB, the appropriate supplemental 
eCRF should be completed.
Intensity of adverse event
The intensity grading of AEs will be performed according to Rheumatology Common 
Toxicity Criteria (RCTC) Version 2.0 developed by OMERACT (R13-3515). See 
Appendix 10.3 for intensity/severity classification.
Causal relationship of adverse event
The definition of an adverse reaction implies at least a reasonable possibility of a causal 
relationship between a suspected medicinal product and an adverse event. An adverse 
reaction, in contrast to an adverse event, is characterised by the fact that a causal 
relationship between a medicinal product and an occurrence is suspected.
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 

Risankizumab
1311.20/M15-989 Protocol Amendment 4
EudraCT 2015-001834-15
64
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:
!
The event is consistent with the known pharmacology of the study drug.
!
The event is known to be caused by or attributed to the drug class.
!
A plausible time to onset of the event relative to the time of drug exposure.
!
Evidence that the event is reproducible when the drug is re-introduced.
!
No medically sound alternative aetiologies that could explain the event 
(e.g. pre-existing or concomitant diseases, or co-medications).
!
The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome).
!
An indication of dose-response (i.e. greater effect size if the dose is increased, 
smaller effect size if dose is diminished).
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:
!
No plausible time to onset of the event relative to the time of drug exposure is 
evident (e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days 
/ weeks of drug administration; an allergic reaction weeks after discontinuation of 
the drugconcerned)
!
Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g. after 5 half-lives). Of 
note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger
!
Additional arguments amongst those stated before, like alternative explanation 
(e.g. situations where other drugs or underlying diseases appear to provide a more 
likely explanation for the observed event than the drug concerned).
!
Disappearance of the event even though the study drug treatment continues or 
remains unchanged.
The reason for the decision on causal relationship for unlisted AEs needs to be provided in 
the (e)CRF.

The Investigator shall maintain and keep detailed records of all AEs in their patient files.
The following must be collected and documented on the appropriate CRF(s) / eCRF by 
the Investigator:
!
From signing the informed consent onwards through the Residual Effect Period 
(REP), until individual patient's end of trial: all AEs (serious and non-serious) and all 
AESIs.
The residual effect period (REP) for BI 655066/ABBV-066 (risankizumab) is defined as 
20 weeks after the last trial medication application. Therefore, all AEs which occurred 
through the treatment phase and throughout the REP will be considered as on treatment 
(see Section 7.3.3). Events which occurred after the REP will be considered as post 
treatment events.
AE reporting to sponsor and timelines
In the event of an SAE, whether associated with study drug or not, the Investigator will 
notify Clinical Pharmacovigilance within 24 hours the site being made aware of the SAE 
by entering the SAE data into the electronic data capture (EDC) system.  SAEs that occur 
prior to the site having access to the RAVE system, or if RAVE is not operable, should be 
documented on the SAE Non-CRF forms and emailed (preferable route) or faxed to 
Clinical Pharmacovigilance within 24 hours of the site being made aware of the SAE.

RSI in place at the time of occurrence of the 'suspected' Serious Adverse Reaction will be 
used to assess expectedness.
Information required
The following should also be recorded as an (S)AE in the (e)CRF and SAE form (if 
applicable):
!
Worsening of the underlying disease or of other pre-existing conditions
!
Changes in vital signs, ECG, physical examination and laboratory test results, if they 
are judged clinically relevant by the investigator
If such abnormalities already pre-exist prior trial inclusion they will be considered as 
baseline conditions.
All (S)AEs, including those persisting after individual patient's end of trial must be 
followed to a satisfactory conclusion or no further information can be obtained.
Pregnancy
Pregnancy in a study subject must be reported to AbbVie within 1 working day of the site 
becoming aware of the pregnancy. Subjects who become pregnant during the study must 
be discontinued from study drug.
Information regarding a pregnancy occurrence in a study subject and the outcome of the 
pregnancy will be collected.
Pregnancy in a study subject is not considered an AE.  However, the medical outcome of 
an elective or spontaneous abortion, stillbirth, or congenital anomaly is considered an 
SAE and must be reported to AbbVie within 24 hours of the site becoming aware of the 
event.
5.2.3
Assessment of safety laboratory parameters
The laboratory tests will be performed as listed in Table 5.2.3: 1and Table 5.2.3: 2. 
Instructions on sample collection, sample handling/ processing, and sample shipping will 
be provided to the investigator site file by the central laboratory. For time points of 
laboratory sampling, see Flow chart 1, Flow chart 2 and Flow chart 3.

Laboratory results of the patients will be available in real time to the respective 
investigator and to the clinical monitor of each country (central laboratory website), and 
selected abnormal laboratory alerts will be sent automatically to the sites and to the 
sponsor in real time. PK, PD and biomarker data will not be available to the investigators 
or local clinical monitors but the Trial Team (sponsor) in a blinded manner and when 
relevant, in an unblinded manner to the DMC. Laboratory results will be reported as the 
absolute value of the measurement obtained on a study patient.
Clinically relevant laboratory values will be commented on in the eCRF. A clinically 
relevant value may be either in- or outside the reference range. Clinically relevant 
abnormal laboratory test results must be repeated using an unscheduled visit lab kit and 
must be repeated until normalisation or stabilisation or until an alternative explanation has 
been found. Clinically relevant abnormal laboratory values will be also graded for 
intensity by using RCTC Version 2.0 criteria.

Medical examination
Complete physical examination will include vital sign assessment and general appearance 
as well as evaluation for fistulas and of all organ systems (eyes, ears, nose, mouth, and 
throat, neck, respiratory, cardiovascular, chest, gastrointestinal, lymphatic, 
musculoskeletal, skin, neurologic and psychiatric). Targeted physical examination will 
include vital sign assessment and evaluation for fistulas and of organ systems associated 
with AE(s) symptoms or laboratory abnormalities.
The medical examination will be carried out at screening. It will include documentation of 
patient information, informed consent, demographics including height, weight and 
smoking and alcohol history, relevant medical history and concomitant medication, 
review of inclusion/exclusion criteria, review of vital signs, 12-lead ECG and laboratory, 
and a complete physical examination.
5.2.5

Local tolerability at the administration site of the subcutaneous injection will be assessed 
by the investigator according to "swelling", "induration", "heat", "redness", "pain", or 
"other findings".
5.2.6
Infusion reaction
In case of an infusion reaction monitor the patient per standard of care, grade the intensity 
of the reaction according to RCTC grading (Appendix 10.3) and proceed as described in 
Section 4.2.2.1. Also draw plasma sample for IgE and ADA (anti-drug antibodies), as 
detailed in the CTP Section 5.5.2.2. and the Lab Manual.

It will be recorded after the patients have rested for at least 5 minutes in supine position at 
Visit 1. Six limb leads, as specified by Einthoven (I, II and III) and Goldberger (aVR, 
aVL, aVF), and six pre-cordial leads (V1–V6), according to Wilson, will be used. The 
investigator or a designate will evaluate whether the ECG is normal or abnormal and 
whether it is clinically significant, if abnormal. Additionally, any occurrence of re- or 
depolarization disorders, arrhythmic disorders or other abnormalities will be assessed.
The electronic version of the ECG is regarded as source data. Dated and signed printouts 
will be stored in the patient's medical file.
ECGs may be repeated for quality reasons and the repeat used for analysis. Additional 
ECGs may be collected by the investigator for safety reasons. All clinically-significant 
abnormalities, even transient, must be followed by ECG performed at every subsequent 
visit.
Clinically relevant abnormal findings will be reported as adverse events.

APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are standard measurements and will be 
performed in order to monitor patients'/patients' safety and to determine pharmacokinetic 
and pharmacodynamic parameters in an appropriate way.

Risankizumab
1311.20/M15-989 Protocol Amendment 4

73
The scheduled measurements are appropriate to see drug induced changes in vital signs, 
standard laboratory values and ECG. These endpoints are standard and accepted for 
evaluation of safety and tolerability of a biologic drug and are widely used in this kind of 
study.
The pharmacokinetic parameters and measurements outlined in Section 5.5 are generally 
used assessments of drug exposure. The biomarkers and pharmacodynamic parameters 
and measurements outlined in Section 5.6 and 5.7 are of an exploratory nature only.
5.5
DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
Detailed information on timings for dosing, PK and ADA sampling are listed in 
Flow chart 1, Flow chart 2 and Flow chart 3. Date and exact clock time of administration 
as well as of PK sampling times will be recorded.
They will be documented in the CRFs by the medical personnel or sent as electronic files.
These actual sampling times will be used for determination of PK parameters. If the 
sampling visit represents a drug administration visit, sampling for PK will occur prior to 
the drug administration.
5.5.1
Pharmacokinetic endpoint(s)
The collected concentrations from all patients will be summarized through descriptive 
statistics. If data allow, steady state pharmacokinetic parameters of BI 655066/ABBV-066 
(risankizumab) will be evaluated as appropriate using non-compartmental analysis 
methods according to sponsor's standard
Pharmacokinetic data may additionally be analysed using population pharmacokinetic 
approaches. For this purpose data may also be combined with data from other trials. 
Modelling activities will be planned and documented separately according to internal and 
external guidelines and SOPs.
5.5.2
Methods of sample collection
5.5.2.1
Plasma sampling for pharmacokinetic analysis
For the quantification of analyte plasma concentrations, approximately 2.5 mL of blood 
will be taken from a forearm vein into a K3EDTA (ethylenediaminetetraacetic acid) 

Risankizumab
1311.20/M15-989 Protocol Amendment 4
EudraCT 2015-001834-15
74
anticoagulant blood-drawing tube at the time points listed in the Flow chart 1, 
Flow chart 2 and Flow chart 3 under PK sampling.
The blood samples must be taken from the forearm vein that is not receiving the i.v. 
infusion.
Mix the K3EDTA-anticoagulated blood samples gently and place on ice until 
centrifugation at approximately +4°C. The blood will be centrifuged to produce plasma as 
soon as possible after collection, but not later than 30 minutes after withdrawal. 
Centrifugation will last for approximately 10 minutes (at 2000 x g to 4000 x g) at 
approximately +4°C. Two aliquots of EDTA plasma samples will be obtained in two 
labelled (label to include: trial number, patient number, visit, PTM, aliquot 1 or 2, plasma, 
and PK) polypropylene cryotubes. The two aliquots should contain approximately 0.5 mL 
of plasma each. The plasma samples will be stored in a freezer set to -20°C or below at 
the clinical site(s) until shipment on dry ice to the central lab (with dry ice sufficient for 
3 days transit), then stored in a freezer set to –70°C or below at the central lab until 
shipment to the analytical laboratory.  Both aliquots will be shipped (in separate 
shipments with dry ice sufficient for 3 days transit) to the analytical laboratory for the 
determination of BI 655066/ABBV-066 (risankizumab).  Both aliquots will be stored in in 
a freezer set to –70°C or below at the analytical laboratory until the finalization of the 
clinical trial report.
5.5.2.2
Plasma sampling for assessment of anti-drug antibody
For the assessment of anti-drug antibody, approximately 2.5 mL of blood will be taken 
from a forearm vein into a K3EDTA (ethylendiaminetetraacetic acid) anticoagulant blood-
drawing tube at the time points listed in the Flow chart 1, Flow chart 2 and Flow chart 3
under anti-drug antibody (ADA).
Mix the K3EDTA-anticoagulated blood samples gently and place on ice until 
centrifugation at approximately +4°C. The blood will be centrifuged to produce plasma as 
soon as possible after collection, but not later than 30 minutes after withdrawal. 
Centrifugation will last for approximately 10 minutes (at 2000 x g to 4000 x g) at 
approximately +4°C. Two aliquots of EDTA plasma samples will be obtained in two 
labelled (label to include: trial number, patient number, visit, PTM, aliquot 1 or 2, plasma, 
and ADA) polypropylene cryotubes. Both aliquots will contain approximately 0.5 mL of 
plasma each. The plasma samples will be stored in a freezer set to -20°C or below at the 
clinical site(s) until shipment on dry ice to the central lab (with dry ice sufficient for 
3 days transit), then stored in a freezer set to -70°C or below at the central lab until 
shipment to the analytical laboratory.  Both aliquots will be shipped (in separate

shipments with dry ice sufficient for 3 days transit) to the analytical laboratory for 
assessment of potential ADA to BI 655066/ABBV-066 (risankizumab).  Following the 
finalization of the ADA bioanalytical report, selected ADA aliquots will be transferred to 
long term storage for possible/ additional ADA characterization in the future.
5.5.3
Analytical determinations
BI 655066/ABBV-066 (risankizumab) concentrations will be determined by a validated 
Enzyme Linked Immunosorbent Assay (ELISA).
The presence of ADA to BI 655066/ABBV-066 (risankizumab) will be assessed via a 
tiered approach using a validated electrochemiluminescence assay (screening, 
confirmatory, and titration analysis as appropriate). Samples that are confirmed positive 
will then be characterized in a validated neutralizing antibody (Nab) assay.
5.6
BIOMARKER(S)
5.6.1
Endpoints based on biomarker(s)
Biomarkers associated with Crohn's disease and the IL-23 pathway will be assessed in 
serum from patients' pre and post treatment with BI 655066/ABBV-066 (risankizumab). 
Changes in protein levels of disease specific markers such as but not limited to 
β defensin 2, neutrophil gelatinase associated lipocalin (NGAL), and S-100 proteins (A7, 
A8, A12) pre and post treatment with BI 655066/ABBV-066 (risankizumab) will be 
assessed. These biomarkers are considered exploratory and respective assays will be 
qualified to meet the required performance criteria.
Serum samples will be collected at time points indicated in Flow chart 1, Flow chart 2 and 
Flow chart 3 for the analysis of biomarkers. After completion of the study these samples 
may be used for not yet specified non-genetic biomarker analyses associated with 
autoimmune diseases as well as method development and evaluation. Samples will be 
stored for a maximum of 3 years (under consideration of local legislation) upon signature 
of the final study report.
5.6.2
Methods of sample collection
For the assessment of soluble biomarkers in serum, approximately 8.5 ml of blood will be 
collected from a forearm vein into a serum separation tube at time points indicated in 
Flow chart 1, Flow chart 2 and Flow chart 3. The blood will be thoroughly mixed with 
clotting activation agent by gently inverting the tube not less than five times and will be 
allowed to clot for at least 30 mins, but for a maximum of 60 mins, with the tube standing

upright. The tube is then centrifuged at 1500 to 2000 xg for 15 mins until clot and serum 
are separated by a well formed barrier. The serum will then be divided into at least 
6 aliquots (in polypropylene tubes) of at least 500 μl and will be frozen immediately at 
approximately -20°C or below until shipment on dry ice.

PHARMACOKINETIC - PHARMACODYNAMIC RELATIONSHIP
No formal analysis of pharmacokinetic/pharmacodynamic relationships is planned. If the 
data suggest a pharmacokinetic/pharmacodynamic relationship of special parameters, eg., 
CDAI, an exploratory analysis may be performed.
Correlation between drug concentration and response may be made if adequate data are 
available. In addition, exploratory correlations may also be made between drug 
concentration and AEs.
Data may also be used to develop pharmacokinetic/pharmacodynamic models using 
nonlinear mixed effect modeling techniques, if feasible. For this purpose data may also be 
combined with data from other trials. Modeling activities will be planned and documented 
separately according to internal and external guidelines and SOP.

VISIT SCHEDULE
All patients are to adhere to the visit schedule as specified in the Flow chart 1, 
Flow chart 2 and Flow chart 3. Additional unscheduled visits for the purpose of re-testing

DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening period
After patients have been informed about the study, written informed consent in 
accordance with GCP and local legislation must be obtained prior to any study related 
procedures taking place. Patients will be assigned a number and enrolment must be 
recorded in eCRF pages.
Visit 1 of this study should preferably be performed in one visit combined with the last 
visit of preceding trial 1311.6 or during the interim period of maximum 5 days after 
completion of the last visit in 1311.6.
Patients rolling-over directly from preceding 1311.6 trial eligibility will be assessed based 
on the patient diary dispensed earlier at the 1311.6 trial containing symptoms over 7 days. 
Investigators will review the diary in order to assess the CDAI score. The hematocrit 
result to calculate the CDAI score must be used from visit 1. If an EoT (or at the last 
preceding trial visit E1 or E5) colonoscopy has not been performed during 1311.6, it must 
be performed between V1 and V2 in 1311.20/M15-989.
Patients successfully completing the 1311.6 trial before initiation of the 1311.20/M15-989 
trial, will be assessed for eligibility based on a newly dispensed patient diary at visit 1. At 
the following 1.1 visit the investigator will review the diary in order to assess the CDAI 
score. The hematocrit result to calculate the CDAI score must be used from visit 1. If an 
EoT colonoscopy has not been performed during 1311.6 or if the patient had a treatment 
interruption followed by a clinical relapse, it must be performed between V1 and V2 in 
1311.20/M15-989.

6.2.2
Treatment periods
If upon completion of screening patient eligibility was confirmed by maintaining clinical 
response or remission (CDAI drop ≥100 from baseline of 1311.6 or CDAI < 150) patients 
can directly be assigned to open label s.c. maintenance treatment (see Flow charts 1 and 
Flow chart 2).
However, if clinical response or remission has been lost after end of treatment in 1311.6 
and/or at screening for 1311.20/M15-989, patients will receive open label i.v. re-induction 
treatment with three infusions of 600 mg each every 4 weeks. After re-induction 
eligibility will be re-assessed. If clinical response or remission compared to 
1311.20/M15-989 study entry is achieved patients will switch to s.c. maintenance 
treatment (see Flow chart 3).
During the s.c. maintenance treatment patients will be administered BI 655066/ABBV-066 
(risankizumab) 180 mg every 8 weeks. Medication will be assigned by IRT. All study 
medication will be stored and administered on site by authorized study staff only.
For details on the study assessments refer to Flow chart 1, Flow chart 2 and Flow chart 3.
6.2.3
End of trial and follow-up period
The follow up period is 20 weeks after the last administration of study medication. Refer

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN - MODEL
This trial is a single group, open label extension study of BI 655066/ABBV-066 
(risankizumab) in patients with moderately to severely active CD. The patients enrolled in 
this study are those that achieved clinical response to previous treatment with 
BI 655066/ABBV-066 (risankizumab). There will be no statistical testing performed.
7.2
NULL AND ALTERNATIVE HYPOTHESES
There is no formal statistical hypothesis test planned.
7.3
PLANNED ANALYSES
Descriptive analyses will be used to analyse the proportion of participants achieving the 
efficacy endpoints. The study is designed to gain extensive documentation of safety and 
efficacy.
7.3.1
Primary analyses
There are no primary analyses for efficacy.
7.3.2
Secondary analyses
There is no secondary analyse for efficacy.
Other efficacy endpoints will be summarized descriptively by visit. They will be tabulated 
and descriptive statistics will be provided.
Additional further endpoints may be defined in the Trial Statistical Analysis Plan (TSAP).
7.3.3
Safety analyses
Since the main objective of this study is long term safety, the primary focus would be on 
incidence of drug-related AE and serious infection.

Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA) coding dictionary. Summary tables and listings will be produced. All adverse 
events with an onset between start of treatment and end of the residual effect period 
(REP), a period of 20 weeks after the last dose of trial medication, will be assigned to the 
treatment period for evaluation.
All treated patients will be included in the safety analysis.
Statistical analysis and reporting of adverse events will concentrate on treatment-emergent 
adverse events. To this end, all adverse events occurring between start of treatment and 
end of the residual effect period will be considered 'treatment-emergent'. Adverse events 
that start before first drug intake and deteriorate under treatment will also be considered as 
'treatment-emergent'. Frequency, severity, and causal relationship of adverse events will 
be tabulated by system organ class and preferred term after coding according to the 
current version of the Medical Dictionary for Drug Regulatory Activities (MedDRA). 
Safety analyses will focus on adverse events related to early discontinuation, immune 
suppression and injection site effects.
Laboratory data will be analysed both quantitatively as well as qualitatively. The latter 
will be done via comparison of laboratory data to their reference ranges. Values outside 
the reference range as well as values defined as clinically relevant will be highlighted in 
the listings. Treatment groups will be compared descriptively with regard to distribution 
parameters as well as with regard to frequency and percentage of patients with abnormal 
values or clinically relevant abnormal values. Analysis of laboratory measures will focus 
on haemotologic measures of immune suppression.
Vital signs, physical examinations, or other safety-relevant data observed at screening, 
baseline, during the course of the trial and at the end-of-trial evaluation will be assessed 
with regard to possible changes compared to findings before start of treatment.
7.3.4
Interim analyses
No formal interim analyses are planned. However since this is an open label study, 
interim analyses may be performed as needed after approximately 20 patients complete 
the study.
7.3.5
Pharmacokinetic analyses
Refer to Section 5.5.1 for pharmacokinetic parameters to be calculated using 
noncompartmental analysis (NCA). The derivation of pharmacokinetic parameter is 
described in sponsor's standard operating procedure.

Risankizumab
1311.20/M15-989 Protocol Amendment 4
EudraCT 2015-001834-15
81
All evaluable patients who received at least one dose of BI 655066/ABBV-066 
(risankizumab) will be included in the pharmacokinetic analysis. Patients who are 
considered as not evaluable will be listed with their individual plasma concentrations and 
individual pharmacokinetic parameters, however, will not be included in descriptive 
statistics for plasma concentrations, pharmacokinetic parameters or other statistical 
assessment.
Concentrations will be used for graphs and calculations in the format that is reported in 
the bioanalytical report. Noncompartmental pharmacokinetic analyses of the plasma 
concentration-time data will be performed using a validated software program. Only 
concentrations within the validated concentration range will be used for the calculation of 
pharmacokinetic parameters.
Plasma concentrations will be plotted graphically versus time for all evaluable patients as 
listed in the drug plasma concentration-time tables. The actual sampling times will be 
used for individual drug plasma concentration-time plots. For the presentation of the mean 
profiles, the arithmetic mean and the planned blood sampling times will be used.
The following descriptive statistics will be calculated for BI 655066/ABBV-066 
(risankizumab) concentrations as well as for all pharmacokinetic parameters:  N, 
arithmetic mean, standard deviation, minimum, median, maximum, arithmetic coefficient 
of variation, geometric mean, and geometric coefficient of variation. The data format for 
descriptive statistics of concentrations will be identical with the data format of the 
respective concentrations. The descriptive statistics of pharmacokinetic parameters will be 
calculated using the individual values with the number of decimal places as provided by 
the evaluation program. Then the individual values as well as the descriptive statistics will 
be reported with three significant digits in the clinical trial report.
7.3.6
Pharmacodynamic analyses
Baseline levels and changes from baseline in serum protein biomarkers will be described 
over time. Correlations between change from baseline in CDAI scores, endoscopic scores 
and biomarker levels will be explored. In addition, the relationships, between drug 
concentrations, clinical efficacy, and selected biomarkers will be explored. The details of 
these analyses will be included in the SAP.
7.3.7
Pharmacogenomic analyses
Not applicable.

RANDOMISATION
There is no randomisation for this study. All patients will be assigned to the same regimen 
and dose of BI 655066/ABBV-066 (risankizumab) , regardless of the treatment and dose 
received in the 1311.6 trial.
7.6
DETERMINATION OF SAMPLE SIZE
The sample size is determined by the completion of previous trial and the consenting for 
the extension.

CLINICAL EVALUATION OF LIVER INJURY
10.1.1
Introduction
Alterations of liver laboratory parameters, as described in Section 5.2.2.1 (Adverse Events 
of Special Interest), are to be further evaluated using the following procedures: 
10.1.2
Procedures
Repeat the following laboratory tests: ALT, AST, and bilirubin (total and direct) - within 
48 to 72 hours and provide additional blood sample to the central laboratory for automatic 
reflex testing of the below listed laboratory parameters. Only in case whereby the central 
laboratory is not immediately available (e.g. if the logistics are such that the patient's 
repeat specimen would not reach the central laboratory in a reasonable timeframe), ALT, 
AST, and bilirubin (total and direct) will be evaluated by local laboratory and results are 
made available to the investigator and to BI as soon as possible. If in such a case ALT 
and/or AST > 3 fold ULN combined with an elevation of total bilirubin > 2 fold ULN are 
confirmed, results of the laboratory parameters described below must be made available to 
the investigator and to BI as soon as possible.
