Synopsis  
Protocol Title: A 24-Week Multicenter, Open-Label, Single-Arm, Phase 4 Study to Evaluate the 
Safety of Ixekizumab in Patients with Moderate-to-Severe Plaque Psoriasis and/or Active 
Psoriatic Arthritis in India 
Brief Title: A study to investigate the safety of ixekizumab in participants aged ≥18 years with 
moderate-to-severe plaque psoriasis and/or active psoriatic arthritis in India 
Rationale: 
The rationale for this post-approval Phase 4 study is to evaluate the safety and tolerability when 
ixekizumab is administered to participants in India with moderate-to-severe plaque psoriasis 
(PsO) and/or active psoriatic arthritis (PsA). This Phase 4 safety study is being performed as per 
conditional marketing approval from the Central Drugs Standard Control Organization 
(CDSCO), India. As per permission reference, Lilly has committed to conduct a Phase 4 study 
with ixekizumab in India. In addition to the established safety profile for adult PsO, and PsA, the 
safety and tolerability data in Indian population from this study are intended to: 
 further support the known safety profile for ixekizumab in adult participants with PsO 
and PsA, and  
 establish a better understanding of the benefit-risk relationship for ixekizumab in 
participants with PsO and PsA.

Q4W (i.e., at Weeks 4, 8, 12, 16 and 20). 
Statistical Analysis: 
Adverse events and treatment-emergent adverse events will be summarized and analyzed for the 
safety population for the combined Period 2 (Induction Dosing Period) and Period 3 
(Maintenance Period), including the number and percentage of participants who reported 
TEAEs, TEAEs by maximum severity, death, SAEs, TEAEs related to study treatment, AEs 
leading to treatment discontinuation, and TEAEs of special interest.  
Efficacy analyses in the secondary objectives specific to PsO and PsA will be conducted on the 
PsO with no active PsA and active PsA participants with at least 1 dose of study intervention and 
will be summarized with number of responders, response rate and its corresponding 95% 
confidence intervals (CIs) using normal approximation.  
Number of Participants: 
Approximately 250 participants (PsO: 150 participants; PsA: 100 participants) are planned to be 
enrolled into this study and, assuming discontinuations of approximately 10%, approximately 
225 participants should complete the 24-week period of treatment.

Introduction  
2.1. 
Study Rationale  
The rationale for this post-approval Phase 4 ixekizumab study is to evaluate the safety and 
tolerability when ixekizumab is administered to participants in India with moderate-to-severe 
plaque psoriasis (PsO) and/or active psoriatic arthritis (PsA). Participants with 
moderate-to-severe plaque psoriasis are defined as those with PASI ≥12, sPGA ≥3, and BSA 
≥10%. This Phase 4 safety study is being performed as per conditional marketing approval from 
the Central Drugs Standard Control Organization (CDSCO), India. Per permission reference, 
Lilly has committed to conduct a Phase 4 study with ixekizumab in India. In addition to the 
established safety profile for adult PsO, and PsA, the safety and tolerability data in Indian 
population from this study are intended to: 
 further support the known safety profile for ixekizumab in adult participants with PsO 
and PsA, and  
 establish a better understanding of the benefit-risk relationship for ixekizumab in 
participants with PsO and PsA. 
2.2. 
Background  
Psoriasis is a common, lifelong and life-shortening, chronic inflammatory skin disease 
manifested by prototypic red, thick, and scaly plaques. PsO is the most common form and has 
been shown to have a significant impact on the overall health of participants. Along with an 
association with inflammatory arthritis in the form of PsA, PsO is associated with increased risk 
for multiple comorbid conditions, including myocardial infarction (MI) and stroke, metabolic 
syndrome, diabetes mellitus, chronic renal insufficiency, and liver abnormalities (Yeung et al. 
2013). The lifespan of participants with moderate-to-severe PsO may be shortened by as many as 
5 years, partly due to association with comorbidities (Gelfand et al. 2006; Ryan and Kirby 2015). 
The worldwide prevalence of PsO is 2% to 3% (Christophers 2001; IFPA 2017; NPF 2018) 
while in India the incidence is 0.44% to 2.2%, and the prevalence is 0.8% to 2.3% (Dogra and 
Yadav 2010). Almost one-third of participants with PsO in the United States (US) suffer from 
moderate-to-severe disease (Dubin et al. 2003). Certain symptoms, such as itching, can 
especially impact the quality of life and is detrimental to work productivity and sleep (Zimolag 
et al. 2009; Gowda et al. 2010; Janowski et al. 2014; Lebwohl et al. 2014). 
Early treatments for PsO obtained 50% to 75% improvement in skin clearance; however, 
expectations for treatment goals of efficacy are expected to be higher as new and more 
efficacious therapies have emerged. Recent studies of biologics which block the interleukin-17 
(IL-17) or interleukin-23 (IL-23) pathways, both central to PsO pathogenesis (Leonardi et al. 
2012; Langley et al. 2014; Sofen et al. 2014; Gordon et al. 2015; Griffiths et al. 2015; Krueger et 
al. 2015; Lebwohl et al. 2015; Papp et al. 2015), have demonstrated substantial efficacy. 
Complete skin clearance and improved long-term efficacy have increasingly become the desired 
treatment outcomes (Gniadecki et al. 2015; Bartos et al. 2016). Some studies have suggested that

increased levels of clearance resulted in greater improvement in quality of life (Takeshita et al. 
2014; Feldman et al. 2016; Fairchild et al. 2017). 
Ixekizumab (LY2439821) is a humanized immunoglobulin G (IgG) subclass 4 monoclonal 
antibody (MAb) designed and engineered to selectively inhibit IL-17A. It binds with high 
affinity (<3 pM) and specificity to IL-17A, a proinflammatory cytokine. Neutralization of 
IL-17A by ixekizumab has been shown to reduce excess keratinocyte proliferation and activation 
(Krueger et al. 2012). Ixekizumab does not bind the other members of the IL-17 family (IL-17B, 
IL-17C, IL-17D, IL-17E, or IL-17F). 
Ixekizumab has demonstrated efficacy at both short- and long-term time points, with a favorable 
safety profile (Griffiths et al. 2015, Gordon et al. 2016, Strober et al. 2017). In all 3 pivotal Phase 
3 studies (the UNCOVER studies), ixekizumab was superior to placebo with respect to all 
primary and major secondary endpoints. In I1F-MC-RHAJ study, the primary objective was met, 
as the percentage of participants who achieved Psoriasis Area and Severity Index (PASI) 75 at 
Week 12 (Visit 8) was superior to placebo in all ixekizumab dose groups, including statistically 
significant improvements (p<0.001) compared with placebo for the 25-mg, 75-mg, and 150-mg 
ixekizumab dose groups. The time course of the PASI 75 response by dose groups demonstrated 
increasing rapidity of onset of effect with increasing doses.  
In the UNCOVER studies, 32% to 42% of participants who received treatment with ixekizumab 
had complete resolution (PASI 100 or static Physician Global Assessment [sPGA] score of 0; 
versus none in the placebo group) of their PsO at Week 12; high levels of clinical response were 
maintained with continued exposure to ixekizumab 80 mg every 4 weeks (Q4W) through 
Week 60 with at least 50% of participants maintaining or attaining PASI 100 (Gordon et al. 
2016). In the UNCOVER-2 and UNCOVER-3 studies, ixekizumab had greater efficacy than 
etanercept, a tumor necrosis factor inhibitor (TNFi); 40.5% of participants treated with 
ixekizumab 80 mg every 2 weeks (Q2W), compared with 5.3% of etanercept‐treated participants, 
achieved PASI 100 after 12 weeks (Griffiths et al. 2015, Gordon et al. 2016). In a Phase 3 
head-to-head study (IXORA-S), ixekizumab demonstrated superiority over the IL-12/23 
antagonist ustekinumab in participants with moderate-to-severe PsO at Week 12; this trend was 
maintained through Week 52. The majority (76.5%) of ixekizumab-treated participants sustained 
a PASI 90 response through 1 year, and more than one-half of ixekizumab-treated participants 
(52.2%) had completely clear skin at Week 52. The corresponding rates for the 
ustekinumab-treated participants were 59.0% and 35.5%, respectively.  
Studies of ixekizumab suggest ability to achieve PASI 90 (as shown in the VOYAGE studies). 
Ixekizumab also demonstrated a high percentage of participants achieving PASI 100, and a rapid 
onset of skin improvement after administration of ixekizumab (UNCOVER). Long-term 
evaluation of ixekizumab in a study, in which safety is tested, will provide important information 
to clinicians trying to determine long-term safety of drug class is the best for a given participant. 
The purpose of this study is to evaluate efficacy and safety, as well as rapidness of efficacy, of 
ixekizumab. 
In both UNCOVER-2 and UNCOVER-3 studies combined, the most common (≥2% of all 
participants given ixekizumab) were nasopharyngitis, upper respiratory tract infection, 
injection-site reaction, injection-site erythema, injection-site pain, pruritus, headache, and 
arthralgia. Most treatment-emergent adverse events (TEAEs) were mild or moderate in severity. 
Serious adverse events (SAEs) were reported by ≤2% of participants in each treatment group

across both studies. No deaths were recorded in either study. Rates of SAEs and discontinuations 
due to adverse events (AEs) were comparable across study groups in both studies. 
During the extension period of Phase 3 SPIRIT-P1 study in participants with active PsA, 
ixekizumab Q4W or Q2W treatment demonstrated sustained efficacy in key PsA domains with a 
safety profile consistent with other studies investigating ixekizumab. Phase 3 SPIRIT-P1 study in 
participants with active PsA showed that both the 2-week and 4-week ixekizumab dosing 
regimens improved the signs and symptoms of participants with active PsA and who had 
previously inadequate response to TNFIs, with a safety profile consistent with previous studies 
investigating ixekizumab. 
The purpose of RHCZ Phase 4 safety study is to evaluate safety and tolerability of ixekizumab in 
Indian participants with PsO or PsA. 
More information about the known and expected benefits, risks, and reasonably anticipated AEs 
of ixekizumab may be found in the Copellor® package insert. Information on AEs expected to be 
related to the investigational product may be found in Section 6.2 (Development Core Safety 
Information [DCSI]) of the Investigator’s Brochure (IB). Information on SAEs that are expected 
in the study population (independent of drug exposure) and that will be assessed by the Sponsor 
in aggregate, periodically during the course of the study, may be found in Section 5 (Effects in 
Humans) of the IB. 
2.3. 
Benefit/Risk Assessment  
Ixekizumab has been demonstrated to be safe and effective for the treatment of participants with 
moderate-to-severe chronic PsO and/or active PsA. The risk profile for participants within this 
study is anticipated to be consistent with the known safety experience for ixekizumab. 
More information about the known and expected benefits, risks, SAEs, and reasonably 
anticipated AEs of ixekizumab are found in the IB. Information on AEs expected to be related to 
the study intervention may be found in Section 6.2 (DCSI) of the IB. Information on SAEs that 
are expected in the study population independent of drug exposure and that will be assessed by 
the Sponsor in aggregate periodically during the course of the study, may be found in Section 5 
(Effects in Humans) of the IB. 
Taking into account the measures taken to minimize risk to participants participating in this 
study, the potential risks identified in association with ixekizumab are justified by the anticipated 
benefits that may be afforded to participants with PsO or PsA.

Study Design  
4.1. 
Overall Design  
Study RHCZ is a prospective, multicenter, open-label, single-arm, Phase 4 study with 4 study 
periods assessing outcomes in terms of AEs and SAEs with ixekizumab when used in 
participants aged ≥18 years for PsO and PsA in Indian population (Section 1.2). 
The following treatment will be assessed in this study for PsO participants with no active PsA 
and PsA participants who meet criteria for moderate-to-severe PsO: 
 Ixekizumab: 80-mg subcutaneous (SC) injection. 
o At Week 0, 160-mg starting dose (two 80-mg injections), followed by 80 mg 
Q2W from Weeks 2 through 12, and then followed by 80 mg Q4W thereafter 
(i.e., at Weeks 16 and 20). 
The following treatment will be assessed in this study for PsA participants who do not meet 
criteria of moderate-to-severe PsO: 
 Ixekizumab: 80-mg SC injection.   
o At Week 0, 160-mg starting dose (two 80-mg injections), followed by 80 mg 
Q4W (i.e., at Weeks 4, 8, 12, 16 and 20). 
The study will consist of 4 periods: 
 Period 1 (Section 4.1.1): Screening Period (Visit 1) will assess participant eligibility 
and occurs approximately 5 to 28 days prior to Period 2 (baseline; Week 0 [Visit 2]). 
 Period 2 (Section 4.1.2): Induction Dosing Period occurring from Week 0 (baseline; 
Visit 2) to Week 12 (Visit 5). 
 Period 3 (Section 4.1.3): Maintenance Period occurring after Week 12 (Visit 5) to 
Week 24 (Visit 6).

The duration of the Screening Period will be 5 to 28 days before the Induction Dosing Period 
(Period 2) and consists of 1 screening visit (Visit 1) to assess participant eligibility. The 
participant will sign the informed consent form (ICF) before any study assessments, 
examinations, or procedures are performed. 
All inclusion and exclusion criteria are provided in Sections 5.1 and 5.2, respectively. Screening 
procedures (including complete medical history, demographics, and substance use) will be 
performed according to the SoA (Section 1.3). At Visit 1, a QuantiFERON®-TB Gold test assay 
may be performed by a Lilly-designated or local laboratory (Section 8.2.7).  
Participants who test positive for latent tuberculosis (TB) at screening may be re-screened once 
following appropriate treatment, as described in Section 8.2.7. 
4.1.2. Induction Dosing Period (Period 2)  
The Induction Dosing Period (Period 2) will occur from Week 0 (baseline; Visit 2) to Week 12 
(Visit 5). 
At Week 0 (baseline, Visit 2), routine safety assessments, laboratory tests, and clinical efficacy 
assessments will be performed on eligible participants, according to the SoA (Section 1.3).  
At Week 4 (Visit 3) and Week 8 (Visit 4), safety and efficacy parameters in study participants 
will be performed according to the SoA (Section 1.3). The investigator or his/her designee is 
responsible for explaining the correct method for dose administration to the participant or

Please refer to Section 6.1, Table RHCZ.6.1, and Table RHCZ.6.2 for a full description of 
treatment groups and dosing during Period 3. 
Participants who discontinue from study intervention for any reason during Period 3 will continue 
to the ETV before entering the Post-Treatment Follow-Up Period (Period 4; Section 4.1.4). 
4.1.4. Post-Treatment Follow-Up Period (Period 4)  
All participants receiving at least 1 dose of study intervention will enter the Post-Treatment 
Follow-Up Period (Period 4) for a minimum of 4 weeks, beginning after their last regularly 
scheduled visit at Week 24 (or the date of their ETV).   
Required study visits should occur at 4 weeks (Visit 801) after the last regularly scheduled visit 
at Week 24 (or the date of the participant’s ETV), except for participants with a concurrent 
infection that requires systemic anti-infective therapy (described below). 
If, at Visit 801, a participant’s neutrophil count is ≥1500 cells/L or greater than or equal to the 
participant’s baseline neutrophil count, the participant’s participation in the study will be 
considered complete unless the investigator determines additional follow-up may be necessary. 
An additional study visit (Visit 802) 8 weeks after Visit 801 may be required for appropriate 
participant management (described below). 
If, at the last scheduled visit or ETV, a participant’s neutrophil count is <1500 cells/L 
(<1.50 × 103/µL or <1.50 GI/L) and less than the participant’s baseline neutrophil count, the 
following measures should be taken: 
 Participants with concurrent infection: If there is a concurrent infection that requires 
systemic anti-infective therapy, the participant should receive appropriate medical 
care and a repeat test for neutrophil count should be performed at least Q4W (or 
sooner as appropriate) until resolution of infection. Upon resolution of infection, the 
neutrophil count should be monitored using the required study visits in the Post-
Treatment Follow-Up Period (Period 4) design at Visits 801 (4 weeks after resolution 
of infection) and 802 (8 weeks after Visit 801); additional visits may be required 
depending on the degree of neutropenia. 
 Participants without concurrent infection: If there is no concurrent infection that 
requires systemic anti-infective therapy, the neutrophil count should be monitored 
using the required study visits in the Post-Treatment Follow-Up Period (Period 4) 
design, Visits 801 (4 weeks post- ETV or last regularly scheduled visit at Week 24) 
and 802 (if necessary); additional visits may be required depending on the degree of 
neutropenia. 
 For Visit 801 and subsequent visits, the following monitoring applies: 
o As long as a participant’s neutrophil count is <1000 cells/L (<1.00 × 103/µL or 
<1.00 GI/L) at any follow-up visit, the participant should return for additional 
visits at least Q4W (unscheduled visits may be required).   
o As long as a participant’s neutrophil count is ≥1000 cells/L and <1500 cells/L 
(≥1.00 × 103/µL and <1.50 × 103/µL or ≥1.00 GI/L and <1.50 GI/L) at any 
follow-up visit, the participant should return for additional visit(s) at least every 
4 to 8 weeks (unscheduled visits may be required).

o If at Visit 802 the participant’s neutrophil count remains <1500 cells/L 
(<1.50 × 103/µL or <1.50 GI/L) and less than the participant’s baseline neutrophil 
count or if the investigator deems additional follow-up may be necessary, the 
investigator in consultation with Eli Lilly and Company (Lilly) or qualified 
designee will determine the appropriate management of the participant and the 
appropriate timing of additional contact(s) or visit(s). 
o If at Visit 802 the participant’s neutrophil count is ≥1500 cells/L (≥1.50 × 103/µL 
or ≥1.50 GI/L) or greater than or equal to the participant’s baseline neutrophil 
count (whichever is lower), the participant’s participation in the study will be 
considered complete unless the investigator deems additional follow-up 
necessary. 
For participants who have entered Period 4, PsO and PsA therapy is allowed, as determined 
appropriate by the investigator.  
Note: Eli Lilly and company will provide study medication only until Week 20. Eli Lilly and 
company will not provide the post-trial/compassionate use for study intervention as it will be 
commercially available in India. 
4.2. 
Scientific Rationale for Study Design  
This study will examine the effect of ixekizumab on participants with moderate-to-severe PsO 
and/or PsA. 
During the Induction Dosing Period (Period 2), participant’s safety and efficacy will be assessed 
at 80 mg Q2W dose for the participants with PsO and PsA participants who meet criteria for 
moderate-to-severe PsO. In PsA participants who do not meet criteria of moderate-to-severe 
PsO, participant’s safety and efficacy will be assessed at 80 mg Q4W dose. During the 
maintenance Period (Period 3), ixekizumab 80 mg Q4W will be studied. 
Safety endpoints are in alignment with the safety endpoints for currently approved PsO and PsA 
therapies, as well as regulatory guidance (EMA 2004). 
The Maintenance Period (Period 3) will permit collection of data for the assessment of safety and 
efficacy of ixekizumab. 
The Post-Treatment Follow-Up Period (Period 4) is for safety monitoring following the last 
treatment period and last study visit. 
4.3. 
Justification for Dose  
Ixekizumab will be studied at the approved dosing regimen for treatment of adults with 
moderate-to-severe -PsO and PsA participants. 
4.4. 
End of Study Definition  
The end of the study is defined as the date of the last visit or last scheduled procedure shown in 
the SoA (Section 1.3). 
A participant is considered to have completed the study if the participant has completed all periods 
of the study including the last visit or the last scheduled procedure shown in the SoA (Section 1.3).

Study Population  
This study will include participants who have presence of moderate to- -severe PsO 
(moderate -to -severe PsO is defined as BSA ≥10, sPGA ≥3, PASI ≥12) and/or active PsA 
(active PsA defined as the presence of at least 
 tender and at least 
 
swollen joints) for at least 6 months, treated in outpatient settings of India, who have given 
written informed consent approved by Lilly, or its designee, and the ethics review board (ERB) 
governing the site. 
Individuals who do not meet the criteria for participation in this study (screen failure) may be 
re-screened only once in the following circumstances:  participants who test positive for latent 
TB at screening may be re-screened following appropriate treatment, as described in 
Section 8.2.7. When re-screening is performed, the individual must sign a new ICF and will be 
assigned a new identification number. 
Study investigator(s) will review patient records and/or patient history and screening test 
results/measurements to determine if the patient meets all inclusion and exclusion criteria to 
qualify for participation in the study.   
Prospective approval of protocol deviations to recruitment and enrollment criteria, also known as 
protocol waivers or exemptions, is not permitted. 
5.1. Inclusion Criteria

[2] 
Male or nonpregnant, nonbreastfeeding female participants. 
Participants of child-bearing potential who are abstinent (if this is 
complete abstinence, as their preferred and usual lifestyle). 
Total abstinence is defined as refraining from intercourse during the 
entirety of the study and for at least 12 weeks following the last dose of 
ixekizumab. Periodic abstinence such as calendar, ovulation, 
symptothermal, post-ovulation methods, and withdrawal are not 
acceptable methods of contraception. 
Otherwise, participants and their partners of childbearing potential must 
agree to use 2 effective methods of contraception, where at least 1 form is 
highly effective for the entirety of the study and for at least 12 weeks 
following the last dose of ixekizumab. 
The following contraception methods are considered acceptable (the 
participant, and their partner, should choose 2, and 1 must be highly 
effective [defined as <1% failure rate per year when used consistently and 
correctly]):

As indicated in the SoA (Section 1.3), the Study Intervention Administration Log will be 
dispensed to all participants or their caregivers. Either the participant or the caregiver will 
compete the Log with the information about injections and bring it to the site at each regular 
study visit. 
Participants’ compliance with ixekizumab will be assessed at each regular visit. Compliance will 
be assessed by the number of injections needed versus the number of injections administered to 
the participants. Deviation(s) from the prescribed dosage regimen should be recorded in the 
electronic case report form (eCRF). 
6.5. 
Dose Modification  
Not applicable. 
6.6. 
Continued Access to Study Intervention after the End of the Study  
Ixekizumab will not be made available to participants at the conclusion of the study. Lilly will 
provide Ixekizumab from Week 0 to Week 20. Last study dose is scheduled at Week 20. 
6.7. 
Treatment of Overdose  
Refer to the IB for ixekizumab. 
6.8. 
Concomitant Therapy  
All concomitant medication taken during the study must be recorded on the Concomitant 
Medication CRF at the study visits indicated in the SoA (Section 1.3). Treatment with 
concomitant PsO and PsA therapies during the study will be permitted only as outlined in the 
inclusion and exclusion criteria (Sections 5.1 and 5.2, respectively) and as described in the 
paragraphs below. Participants taking permitted medications need to be documented to be in 
stable control. After trial enrollment, significant dose escalation of a concomitant medication 
should be discussed with Lilly medical before allowing participant to receive study intervention.

Additional drugs are to be avoided during the study unless required to treat an AE or for the 
treatment of an ongoing medical problem. If the need for concomitant medication arises, the 
investigator should base decisions on the participant and clinical factors. Any additional 
medication (including the limited use of therapeutic agents which, if used under treatment 
regimens other than for treating an AE or for appropriate medical management, might be 
considered PsO/PsA therapies) whether prescription or over-the-counter, used at baseline 
(Week 0, Visit 2) and/or during the course of the study, must be documented with the start and 
stop dates on the Concomitant Medications CRF. 
Participants will maintain their usual medication regimen for other concomitant diseases 
throughout the study unless those medications are specifically excluded in the protocol. 
Participants taking concomitant medications should be on stable doses at the time of baseline 
(Week 0, Visit 2) and should remain at a stable dose throughout the study, unless changes need 
to be made for an AE or for appropriate medical management. Other medications may be 
allowed if approved by the Sponsor or its designee.

Discontinuation of Study Intervention and Participant Discontinuation/ 
Withdrawal  
Discontinuation of specific sites or of the study as a whole are handled as part of Section 10.1, 
Section 10.1.7. 
7.1. Discontinuation of Study Intervention  
Study intervention may be temporarily withheld or permanently discontinued during the study. 
Participants who permanently discontinue study intervention early will undergo early termination 
procedures, which include:  
 an ETV, and 
 PTFU visits (V801 and V802). 
The investigator will complete any AE reporting and follow-up (Section 8.3). 
7.1.1. Permanent Discontinuation from Study Intervention  
In rare instances, it may be necessary for a participant to permanently discontinue (definitive 
discontinuation) study intervention. If study intervention is definitively discontinued, the 
participant will remain in the study to have ETV and PTFU visits. See the SoA (Section 1.3) for 
data to be collected at the time of discontinuation of study intervention and follow-up and for any 
further evaluations that need to be completed. 
Possible reasons leading to permanent discontinuation of study intervention: 
 Participant decision: 
o the participant or the participant’s designee, e.g., parents or legal guardian, 
requests to discontinue the study intervention. 
Participants will be discontinued from the study intervention under the following 
circumstances: 
 Neutrophil (segmented) counts: 
o <500 cells/L 
o ≥500 and <1000 cells/L (based on 2 test results; the second test performed 
within 1 week from knowledge of the initial result) 
o ≥1000 and <1500 cells/L (based on 3 test results) and an infection that is not 
fully resolved 
o WBC count <1000 cells/L (1.00 × 103/L or 1.00 billion/L)  
o absolute neutrophil count (ANC) <500 cells/L (0.50 × 103/L or 0.50 billion/L) 
o lymphocyte count <200 cells/L (0.20 × 103/L or 0.20 billion/L) 
o hemoglobin <6.5 g/dL (<65.0 g/L) 
o platelet count <50,000 cells/μL.

Note: Temporary interruption rules (see Section 7.1.3) must be followed, where 
applicable. For laboratory values that meet permanent discontinuation thresholds, the 
study intervention should be discontinued. However, if in the opinion of the investigator 
the laboratory abnormality is due to intercurrent illness such as cholelithiasis or another 
identified factor, laboratory tests may be repeated. Only when the laboratory value meets 
resumption thresholds following the resolution of the intercurrent illness or other 
identified factor may the investigator restart the study intervention after consultation with 
the Sponsor-designated medical monitor. 
In addition, participants will be discontinued from the study intervention in the following 
circumstances: 
 The participant experiences a severe AE or SAE or has a clinically significant change 
in a laboratory value that, in the opinion of the investigator, merits discontinuation of 
the study intervention and appropriate measures being taken. This includes evidence 
of active viral hepatitis or active tuberculosis (TB). In such cases, the Sponsor or its 
designee is to be notified immediately. 
 Clinically significant systemic hypersensitivity reaction following SC administration 
of study intervention that does not respond to symptomatic medication or results in 
clinical sequelae 
 The participant becomes pregnant 
 The participant develops a malignancy (Note:  participants may be allowed to 
continue if they develop no more than 2 non-melanoma skin cancers during the study) 
 The participant has a positive TB test using QuantiFERON®-TB Gold or T-Spot or 
purified protein derivative (PPD and is assessed as having latent TB infection (see 
Section 8.2.7), and/or develops symptoms or signs of tuberculosis. 
 if the participant develops active suicidal ideation with some intent to act with or 
without a specific plan, 
 
-OR- 
 
if the participant develops suicide-related behaviors,  
  
 then it is recommended that the participant be assessed by a psychiatrist or 
appropriately trained professional to assist in deciding whether the participant is to be 
discontinued from the study. 
 
Participants discontinuing from the study intervention prematurely for any reason should 
complete AE and other follow-up procedures per the SoA (Section 1.3), Safety Assessments 
(Section 8.2), and Adverse Events and Serious Adverse Events (Section 8.3) of this protocol .

ALT or AST >3 × ULN with the appearance of fatigue, nausea, 
vomiting, right upper quadrant pain or tenderness, fever, rash, 
and/or eosinophilia (>5%) 
 
ALP >3 × ULN, when the source of increased ALP is the liver 
 
ALP >2.5 × ULN and TBL > 2 × ULN  
In participants with Gilbert’s syndrome, 
doubling of direct bilirubin should be used 
for drug interruption/ discontinuation 
decisions rather than TBL>2 × ULN. 
ALP >2.5 × ULN with the appearance of fatigue, nausea, vomiting, 
right upper quadrant pain or tenderness, fever, rash, and/or 
eosinophilia (>5%)

Source: FDA 2009. 
 
Resumption of the study intervention can be considered only in consultation with the 
Lilly-designated medical monitor and only if the liver test results return to baseline and if a 
self-limited non-drug etiology is identified.   
7.1.3. Temporary Discontinuation  
In some circumstances, participants may need to temporarily interrupt treatment as a result of 
AEs or abnormal laboratory values that may have an unclear relationship to the study 
intervention. See Section 8.2.7 for details regarding managing participants who test positive for 
TB at any time during the study. 
The abnormal laboratory values as reason for temporary discontinuation of study intervention 
may include HBV DNA results that are reported as positive, or as detecting HBV DNA, but 
HBV DNA is below the level of quantification. The Sponsor’s designated medical monitor 
should be contacted regarding study status of the participant. HBV DNA testing is to be repeated 
as soon as is feasible. If HBV DNA is confirmed as positive, the participant must be permanently 
discontinued from study intervention (Section 7.1.1). 
Participants requiring surgery at any time during the study should interrupt administration of the 
study intervention beginning 8 weeks before the surgery, or as early as possible, and resume 
administration of the study intervention only after complete wound healing.

is prohibited by the protocol and has been demonstrated to be effective for 
treatment of the study indication. In this case, discontinuation from the study 
occurs prior to introduction of the new agent. 
Discontinuation is expected to be uncommon. 
At the time of discontinuing from the study, if possible, an ETV should be conducted, as shown 
in the SoA (Section 1.3). See the SoA for data to be collected at the time of study discontinuation 
and follow-up and for any further evaluations that need to be completed. The participant will be 
permanently discontinued both from the study intervention and from the study at that time. 
If the participant withdraws consent for disclosure of future information, the Sponsor may retain 
and continue to use any data collected before such a withdrawal of consent. If a participant 
withdraws from the study, the participant may request destruction of any samples taken and not 
tested, and the investigator must document this in the site study records. 
7.2.1. Discontinuation of Inadvertently Enrolled Participants  
If the Sponsor or investigator identifies a subject who did not meet enrollment criteria and was 
inadvertently enrolled, a discussion must occur between the Lilly clinical pharmacologist and the 
investigator to determine if the participant may continue in the study. If both agree that it is 
medically appropriate to continue, the investigator must obtain documented approval from the 
Sponsor to allow the inadvertently enrolled participant to continue in the study with or without 
continued treatment with ixekizumab.  Safety follow-up should be performed as outlined in the 
SoA (Section 1.3), Safety Assessments (Section 8.2), and Adverse Events and Serious Adverse 
Events (Section 8.3) of the protocol. 
7.3. Lost to Follow up  
A participant will be considered lost to follow-up if he/she repeatedly fails to return for 
scheduled visits and is unable to be contacted by the study site. Site personnel or designee are

or were, otherwise, unable to be followed up by the site. 
Site personnel, or an independent third party, will attempt to collect the vital status of the 
participant within legal and ethical boundaries for all participants enrolled, including those who 
did not get investigational product. Public sources may be searched for vital status information. 
If vital status is determined to be deceased, this will be documented, and the participant will not 
be considered lost to follow-up.

Study Assessments and Procedures  
Study procedures and their timing are summarized in the SoA (Section 1.3).  
Immediate safety concerns should be discussed with the Sponsor immediately upon 
occurrence or awareness to determine if the participant should continue or discontinue 
study intervention.  
Adherence to the study design requirements, including those specified in the SoA, is 
essential and required for study conduct.  
All screening evaluations must be completed and reviewed to confirm that potential 
participants meet all eligibility criteria. The investigator will maintain a screening log to 
record details of all participants screened and to confirm eligibility or record reasons for 
screening failure, as applicable. 
The joint assessor (or designee) should be a rheumatologist, trained dermatologist or skilled joint 
assessor and will be responsible for completing the joint counts for swelling, tenderness, and 
limited range of motion. Additionally, the assessor will perform the following assessments: 
Physician’s Global Assessment of Disease Activity, PASI, BSA.  
To ensure consistent skin and/or joint evaluation throughout the study, individual participants 
should be evaluated by the same assessor for all study visits whenever possible.  
Investigators or relevant clinical staff will provide age-appropriate explanations to all study 
participants prior to any assessment or procedure. 
8.1. Efficacy Assessments  
The secondary endpoints for PsO group are: 
 Proportion of participants who achieve the following PASI scores:  PASI 75 (defined as 
75% improvement from baseline in PASI) at Week 12 
 Proportion of participants with an sPGA score of 0 or 1 (0, 1) at Week 12. 
The secondary endpoints for PsA group are: 
 Proportion of PsA participants achieving ACR20 at Week 24. 
Exploratory endpoints include, but not limited to, DAS-28-CRP and ACR individual components. 
For PsO participant who also meet active PsA definition, both PsA and PsO outcomes will be 
collected for that participant. Likewise, to fulfill the study objective, PsO outcomes will be 
collected among all the PsA participants with 3% or more BSA of PsO (Table RHCZ.8.1).

8.1.1. Efficacy Assessments   
8.1.1.1.Psoriasis Area and Severity Index (PASI 75, PASI 90, PASI 100)  
The PASI will be used to assess PsO and PsA. The PASI combines assessments of the extent of 
body-surface involvement in 4 anatomical regions (head, trunk, arms, and legs) and the severity of 
desquamation (scaling), erythema, and plaque induration/ infiltration (thickness) in each region, 
yielding an overall score from 0 for no psoriasis up to 72 for the most severe disease (Fredriksson 
and Pettersson 1978). The PASI has been the most frequently used endpoint and measure of 
psoriasis severity in clinical trials (EMA 2004; Menter et al. 2008). A clinically meaningful 
response is a PASI 75, which represents at least a 75% decrease (improvement) from the baseline 
PASI score. As minimum treatment response, the European and German guidelines mention a 
PASI 50 response. Higher levels of clearance (PASI 90), as well as complete resolution of 
psoriasis (PASI 100), have become additional endpoints because of the increasing recognition of 
the association of higher clearance with greater health-related quality of life (Puig 2015).   
Participants achieving PASI 75, 90, or 100 are defined as having an improvement of at least 
75%, 90%, or 100%, respectively, in the PASI, compared to baseline. 
8.1.1.2.Static Physician Global Assessment   
The sPGA is the physician’s determination of the participant’s psoriatic lesions, overall, at a 
given time point. The sPGA is recommended as an endpoint to assess efficacy in the treatment of 
PsO/PsA (EMA 2004). Overall, lesions are categorized by descriptions for induration, erythema, 
and scaling. For the analysis of responses, the participant’s PsO/PsA is assessed as clear (0), 
minimal (1), mild (2), moderate (3), severe (4), or very severe (5). 
8.1.1.3.Percentage of Body Surface Area  
The investigator will evaluate the percentage involvement of PsO/PsA on each participant’s BSA 
on a continuous scale from 0% (no involvement) to 100% (full involvement), in which 1% 
corresponds to the size of the participant’s palm of the hand, including the palm, fingers, and 
thumb (NPF 2018). 
8.1.2. American College of Rheumatology 20, 50, and 70 Responder Index  
ACR20, ACR50, and ACR70 responses are efficacy measures which for which a participants 
must satisfy the following: 
1) ≥20%, ≥50%, and ≥70% improvement from baseline in tender joint count (TJC); and 
2) ≥20%, ≥50%, and ≥70% improvement from baseline in swollen joint count (SJC); and 
3) ≥20%, ≥50%, and ≥70% improvement from baseline in at least 3 of the following 5 ACR 
Core Set criteria: 
a. Patient’s Assessment of Pain Visual Analog Scale (VAS)

ACR20, ACR50 and ACR70 responses will be assessed over Week 24 (Visit 6). 
American College of Rheumatology Core Set   
Tender Joint Count 
For ACR measures, the number of tender and painful joints will be determined by examination 
of 68 joints (34 joints on each side of the participant’s body). The 68 joints to be assessed and 
classified as tender or not tender are detailed in Section 10.7. Any joints that require 
intra-articular injections during the study (according to Section 6.8 should be excluded from 
evaluation from the time of the injection to the conclusion of the study. 
Joints will be assessed for tenderness by pressure and joint manipulation on physical 
examination. The participant will be asked for pain sensations on these manipulations and 
watched for spontaneous pain reactions. Any positive response on pressure, movement, or both 
will then be translated into a single tender-versus-nontender dichotomy. 
Joint assessments will be performed by an independent, blinded assessor to minimize bias. The 
same assessor should preferably perform the TJC and SJC for a given participant particularly 
during the Induction Dosing Period (Period 2) to minimize interobserver variation. The blinded 
joint assessor will not be involved in participant care and is asked not to discuss disease activity 
or treatment with participants or principal investigator. 
Missing, replaced, ankylosed, or arthrodesed joints will be identified by the investigator at the 
Screening Visit and will be excluded from evaluation during the trial. 
Swollen Joint Count 
For ACR measures, the number of swollen joints will be determined by examination of 66 joints 
(33 joints on each side of the participant’s body). The 66 joints to be assessed and classified as 
swollen or not swollen are detailed in Section 10.7. Any joints that require intra-articular 
injections during the study (according to Section 6.8) should be excluded from evaluation from 
the time of the injection to the conclusion of the study. 
Joints will be classified as either swollen or not swollen. Swelling is defined as palpable 
fluctuating synovitis of the joint. Swelling secondary to osteoarthritis will be assessed as not 
swollen, unless there is unmistakable fluctuation. Dactylitis should be counted as 1 joint. 
Missing, replaced, ankylosed, or arthrodesed joints will be identified by the Investigator at the 
Screening Visit and will be excluded from evaluation during the trial. 
Joint assessments will be performed by an independent, blinded assessor to minimize bias. The 
same assessor should preferably perform the TJC and SJC for a given participant particularly 
during the Induction Dosing Period (Period 2) to minimize interobserver variation. The blinded 
joint assessor will not be involved in participant care and will be instructed not to discuss disease 
activity or treatment with participants or principal investigator.

Patient’s Assessment of Pain Visual Analog Scale 
Patient’s Assessment of Pain VAS will be administered only to PsA participants. The question 
related to pain assessment will be included in HAQ-DI assessment. 
The participant will be asked to assess his/her current level of joint pain by marking a vertical 
tick on a 100-mm horizontal VAS where the left end represents no joint pain and the right end 
represents worst possible joint pain. The Patient’s Assessment of Pain VAS should be 
administered prior to the TJC and SJC examinations. 
Results will be expressed in millimeters, measured between the left end of the scale and the crossing 
point of the vertical line of the tick; this procedure is applicable for all VAS used in the trial. 
Patient’s Global Assessment of Disease Activity Visual Analog Scale 
The participant’s overall assessment of his/her PsA activity will be recorded using the 100 mm 
horizontal VAS where the left end represents no disease activity, and the right end represents 
extreme disease activity. 
Physician’s Global Assessment of Disease Activity Visual Analog Scale 
The Investigator will be asked to give an overall assessment of the severity of the participant’s 
current PsA activity using a 100 mm horizontal VAS, where 0 represents no disease activity and 
100 represents extremely active disease. The investigator making the assessment must be a 
rheumatologist or medically qualified physician. The same assessor should preferably perform 
the Physician’s Global Assessment of Disease Activity VAS for a given participant particularly 
during the Induction Dosing Period (Period 2) to minimize interobserver variation. 
Patient’s Assessment of Physical Function as Assessed by the Health Assessment 
Questionnaire-Disability Index 
The HAQ-DI is a patient-reported standardized questionnaire that is commonly used in PsA to 
measure disease-associated disability (assessment of physical function). It consists of 
24 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, 
grip, and other daily activities (Fries et al. 1980; Fries et al. 1982). 
The disability section of the questionnaire scores the participant’s self-perception on the degree 
of difficulty (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, and 
3 = unable to do), covering the 8 domains. The reported use of special aids or devices and/or the 
need for assistance of another person to perform these activities is also assessed. The scores for 
each of the functional domains will be averaged to calculate the functional disability index. 
Details of scoring and calculations are presented in the statistical analysis plan (SAP). 
C-Reactive Protein 
CRP will be the ACR Core Set measure of acute phase reactant. It will be measured with a high 
sensitivity assay at the central laboratory to help assess the effect of ixekizumab on the 
participant’s PsA.   
Disease Activity Score based on C-Reactive Protein  
The DAS28-CRP is a measure of disease activity in 28 joints that consists of a composite 
numerical score utilizing the following variables: TJC, SJC, hs-CRP (measured in mg/L), and 
Patient’s General Assessment recorded by participants on a 0 to 100 mm VAS.

For DAS28-CRP, the 28 joints to be examined and assessed as tender or not tender for TJC and 
as swollen or not swollen for SJC are a subset of those assessed for the TJC and SJC, and include 
14 joints on each side of the participant’s body: the 2 shoulders, the 2 elbows, the 2 wrists, the 
10 metacarpophalangeal joints, the 2 interphalangeal joints of the thumb, the 8 proximal 
interphalangeal joints, and the 2 knees (Smolen et al. 1995). The following equation will be used 
to calculate the DAS28-CRP (Vander Cruyssen et al. 2005): 
 
 
8.1.3. Patient Global Assessment of Disease Activity VAS  
The participant’s overall assessment of his/her PsO and PsA activity will be recorded using the 
100 mm horizontal VAS where the left end represents no disease activity, and the right end 
represents extreme disease activity. 
8.1.4. Physician’s Global Assessment of Disease Activity Visual Analog Scale  
The Investigator will be asked to give an overall assessment of the severity of the participant’s 
current PsO and PsA activity using a 100 mm horizontal VAS, where 0 represents no disease 
activity and 100 represents extremely active disease. The investigator making the assessment 
must be a rheumatologist or medically qualified physician. The same assessor should preferably 
perform the Physician’s Global Assessment of Disease Activity VAS for a given participant 
particularly during the Induction Dosing Period (Period 2) to minimize interobserver variation. 
8.2. Safety Assessments  
Any clinically significant findings from physical examination, vital signs measurements, or 
laboratory measurements that result in a diagnosis and that occur after the participant receives 
the first dose of the study intervention should be reported to the Sponsor or its designee as an AE 
via eCRF. 
Planned time points for all safety assessments are provided in the SoA (Section 1.3). 
8.2.1. Physical Examinations  
The complete physical examination (excluding pelvic, rectal, and breast examinations) will be 
performed according to the SoA (Section 1.3). This examination will determine whether the 
participant meets the criteria required to participate in the study and will also serve as a monitor 
for preexisting conditions and as a baseline for TEAE assessment. All physical examinations 
throughout the study should include an examination of the heart, lungs, and abdomen and a 
visual examination of the skin. 
8.2.2. Vital Signs  
For each participant, vital signs measurements should be conducted according to the SoA 
(Section 1.3). 
Vital signs (sitting BP and pulse) and body temperature will be measured after resting for a 
minimum of 10 minutes at times indicated in the study schedule. At baseline (Week 0, Visit 2), 
Approved on 14 Feb 2023 GMT

Page 57 
Week 12 (Visit 5), and Week 24 (Visit 6), sitting BP and pulse should be measured prior to 
administration of the investigational product and again approximately 1 hour after 
administration.   
Any clinically significant findings from vital signs measurement that result in a diagnosis and 
that occur after the participant receives the first dose of the study intervention should be reported 
to the Sponsor or its designee as an AE via electronic data entry. Additional measurements of 
vital signs may be performed at the discretion of the investigator. 
8.2.3. Electrocardiograms  
For each participant, a 12-lead digital ECG will be collected locally only at screening visit 
according to the Study Schedule (Section 1.3). Participants must be supine for approximately 5 
to 10 minutes before ECG collection and remain supine, but awake, during ECG collection. 
Electrocardiograms will be interpreted by a qualified physician as soon after the time of ECG 
collection as possible, and ideally while the participant is still present, to determine whether the 
participant meets entry criteria and for immediate participant management, should any clinically 
relevant findings be identified. The qualified physician must document his/her review of the 
ECG at the time of evaluation.   
The ECG will be maintained at the site and made available to the Sponsor as requested. 
8.2.4. Evaluation of Disease Relapse  
Patients will be assessed for the presence or absence of relapse at screening based on the 
following definitions: 
a. Assessment of relapse for psoriasis participants:  
Relapse is defined as worsening of psoriasis from the previous routine medical visit by 50% 
PASI or 1% BSA or sPGA ≥3 (Tian and Lai 2016). 
If PASI, BSA, or sPGA are not available in medical report, relapse of psoriasis is defined as 
any worsening of psoriatic lesions that would, if persistent, in most cases require initiation or 
change of systemic therapy for psoriasis. 
During the study period, relapse with ixekizumab would be defined as worsening of psoriasis 
from the previous visit by 50% PASI or 1% BSA or sPGA ≥3. 
Relapse present based on the above definition: Yes/No 
Following details will be collected in addition in all PsO participants: 
 Duration of the psoriasis since diagnosis: 
 Duration of the psoriatic arthritis since diagnosis: 
 Prior systemic medications used for psoriasis:  
o Name of the drug and dose 
o Start date 
o End date 
 Prior systemic medications used for psoriatic arthritis:  
o Name of the drug and dose

b. Assessment of relapse for psoriatic arthritis participants:  
Relapse is defined as an increase in PsA disease activity from the previous routine medical 
records  
 either DAS28 (erythrocyte sedimentation rate [ESR]) >2.6 and DAS28 (ESR) 
increase >0.6 or  
 DAS28 (ESR) increase ≥1.2, irrespective of absolute DAS28(ESR) (Emery et al. 
2020; Helliwell et al. 2021). 
If DAS-28 ESR is not available in medical records, relapse of PsA is defined as any increase 
in disease activity that would, if persistent, in most cases require initiation or change of 
systemic therapy for PsA.  
Relapse present based on the above definition: Yes/No 
Additionally, the following details will be collected in all PsA participants: 
 Duration of the psoriasis since diagnosis: 
 Duration of the psoriatic arthritis since diagnosis: 
 Prior systemic medications used for psoriasis:

8.2.5. Clinical Safety Laboratory Tests  
See Appendix 10.2 for the list of clinical laboratory tests to be performed by a Lilly-designated 
or local laboratory and the SoA (Section 1.3) for the timing and frequency. 
The investigator must review the laboratory results, document this review, and report any 
clinically relevant changes occurring during the study as an AE. The laboratory results must be 
retained with source documents unless a Source Document Agreement or comparable document 
cites an electronic location that accommodates the expected retention duration. Clinically 
significant abnormal laboratory findings are those which are not associated with the underlying 
disease, unless judged by the investigator to be more severe than expected for the participant’s 
condition. 
All laboratory tests with values considered clinically significantly abnormal during participation 
in the study or within a time period equivalent to the maximum 5 half-lives of active 
interventions after the last dose of study intervention should be repeated until the values return to 
normal or baseline or are no longer considered clinically significant by the investigator or 
medical monitor.

 If such values do not return to normal/baseline within a period of time judged 
reasonable by the investigator, the etiology should be identified, and the Sponsor 
notified. 
 All protocol-required laboratory assessments, as defined in Appendix 10.2, must 
be conducted in accordance with the SoA (Section 1.3), standard collection 
requirements, and applicable study laboratory manual. 
If laboratory values from non-protocol specified laboratory assessments performed at an 
investigator-designated local laboratory require a change in participant management or are 
considered clinically significant by the investigator (e.g., SAE or AE or dose modification), then 
report the information as an AE.  
8.2.6. Pregnancy Testing  
See the SoA (Section 1.3) for frequency of pregnancy testing and Appendix 10.2 for additional 
details about these tests. 
At screening 
Serum pregnancy tests will be given prior to the first dose of the study intervention for females 
≥10 years of age (<10 years at investigator discretion) if menarche has been reached or if there is 
reason to believe the participant is sexually active. Pregnancy test results at screening must be 
known prior to first dose of the study intervention. 
During the induction dosing and maintenance period 
Female participants of childbearing potential (age 10 and older if menarche has been reached or 
if there is reason to believe the participant is sexually active, or younger participants per 
investigator assessment of sexual maturity) will undergo a urine pregnancy test at the clinic on a 
quarterly basis during scheduled regular visits through Week 156 or the ETV. Additional urine 
pregnancy testing may be performed at the investigator’s discretion. Participants determined to 
be pregnant will be discontinued from treatment and will no longer be administered study 
intervention (see Section 7.1.1). 
During the post-treatment follow-up period 
As indicated in the SoA (Section 1.3), urine pregnancy tests will be collected during each of the 
post-treatment follow-up visits. 
8.2.7. Chest X-Ray and Tuberculosis Testing  
An anterior-posterior view chest x-ray will be obtained, unless the x-ray or results from a chest 
x-ray obtained within 6 months before the study are available. The chest x-ray or results will be 
reviewed by the investigator or designee to exclude participants with active TB infection prior to 
enrollment. 
Tuberculosis testing will be conducted based on clinical assessment of TB risk (symptoms, signs, 
and known or suspected TB exposure), and as required by local regulations and/or local standard 
of care. Participants with a positive TB test and/or other evidence of active TB should be 
discontinued (Section 7.1.1).

Tuberculosis testing – QuantiFERON® TB Gold will be the preferred testing option for TB. The 
QuantiFERON® TB Gold test may be performed locally or centrally. If the QuantiFERON®-TB 
Gold test is indeterminate (not negative), 1 retest is allowed. If the retest for the 
QuantiFERON®-TB Gold test is indeterminate (not negative), the participant is excluded from 
enrollment in the study. 
In countries where the QuantiFERON®-TB Gold test is not available or due to investigator’s 
judgement (e.g., need to reduce the volume of blood collected), the T-Spot or PPD test may be 
used. In the case of selecting the PPD test, the participant must return within 48 to 72 hours to 
read the skin test.  
A positive PPD skin test response for this study is defined as ≥5-mm induration between 48 and 
72 hours after PPD application, regardless of BCG vaccination history.  
Participants with a PPD skin test ≥5 mm induration or a positive QuantiFERON®-TB Gold or 
T-Spot test but no evidence of active TB, and participants who have a documented history of a 
positive TB test but no documented history of completion of a full, appropriate latent TB 
treatment course, who are assessed as having latent TB infection may be re-screened 1 time and 
may be enrolled without repeating a QuantiFERON®-TB Gold, T-Spot or PPD test if the 
following conditions are met: 
 after receiving at least 4 weeks of appropriate latent TB infection therapy with no 
evidence of hepatotoxicity (ALT/AST must remain ≤2 × ULN) upon retesting of serum 
ALT/AST prior to enrolment, 
 commitment by the participant and the caregiver for the participant to complete a full 
course of standard prophylaxis for TB, and 
 meet all other inclusion/exclusion criteria for participation. 
Such participants must complete appropriate latent TB infection therapy to remain eligible for 
continued study participation. If rescreening occurs within 6 months of the screening chest x-ray, 
a repeat of chest x-ray for considering enrollment is not required. 
If a participant with a positive QuantiFERON®-TB Gold or T-Spot or PPD is fully assessed by 
the investigator and the investigator determines that the participant has no risk factors for and no 
symptoms or signs of Mycobacterium tuberculosis infection, the investigator may contact the 
Sponsor’s medical monitor to discuss the possibility of a false-positive test result. 
Participants with positive TB test results on file: Participants with a documented prior history 
of a positive TB test and participants who have a documented history of completion of an 
appropriate TB treatment regimen for latent or active TB should not have a TB test performed at 
Visit 1. Such participants with no history of re-exposure to TB since their treatment was 
completed and no evidence of active TB are eligible to participate in the study. Participants who 
have had household contact with a person with active TB are excluded unless an appropriate and 
documented course of prophylaxis for TB was completed. 
Participants are to be monitored on a regular basis for any symptoms or signs of active TB and 
for any new risk factors for TB infection, with full medical evaluation including TB testing when 
medically indicated. Participants that exhibit symptoms of active TB should be referred to a 
specialist in the care of participants with TB.

should be repeated within 48 to 72 hours to confirm the abnormality and to determine if it is 
increasing or decreasing, if one or more of these conditions occur: 
If a participant with baseline results of ...  
develops the following elevations: 
ALT or AST <1.5 × ULN 
ALT or AST ≥3 × ULN 
ALP <1.5 × ULN 
ALP ≥2 × ULN 
TBL <1.5 × ULN 
TBL ≥2 × ULN (except for participants with Gilbert’s 
syndrome) 
ALT or AST ≥1.5 × ULN 
ALT or AST ≥2 × baseline 
ALP ≥1.5 × ULN 
ALP ≥2 × baseline 
TBL ≥1.5 × ULN 
TBL ≥2 × baseline (except for participants with Gilbert’s 
syndrome) 
 
If the abnormality persists or worsens, clinical and laboratory monitoring, and evaluation for 
possible causes of abnormal liver tests should be initiated by the investigator in consultation with 
the Lilly-designated medical monitor. At a minimum, this evaluation should include physical 
examination and a thorough medical history, including symptoms, recent illnesses (e.g., heart 
failure, systemic infection, hypotension, or seizures), recent travel, history of concomitant 
medications (including over-the-counter), herbal and dietary supplements, and a history of 
alcohol drinking and other substance abuse.  
Initially, monitoring of symptoms and hepatic biochemical tests should be done at a frequency of 
1 to 3 times weekly, based on the participant’s clinical condition and hepatic biochemical tests. 
Subsequently, the frequency of monitoring may be decreased to once every 1 to 2 weeks, if the 
participant’s clinical condition and laboratory results stabilize. Monitoring of ALT, AST, ALP, 
and TBL should continue until levels normalize or return to approximate baseline levels.

o In participants with baseline ALP ≥1.5 × ULN, the threshold is ALP ≥2 × baseline 
on 2 or more consecutive blood tests; 
 Hepatic event considered to be an SAE; 
 Discontinuation of study intervention due to a hepatic event.  
Note: the interval between the 2 consecutive blood tests should be at least 2 days. 
8.2.8.2.Hepatitis C Testing and Monitoring  
Initial testing for HCV infection includes testing for antibodies to HCV: 
 
If anti-HCV is positive, a serum test for circulating HCV RNA is required. 
 
If HCV RNA test is negative, the participant is not excluded. 
 
If HCV RNA test is positive, the participant is excluded. 
Participants who have had HCV infection and been successfully treated, defined as a sustained 
virologic response (HCV RNA by PCR-negative for at least 24 weeks following treatment 
completion) are not excluded on the basis of HCV as long as HCV RNA test is negative at 
screening. 
If HCV RNA is detected during the study, the study intervention will be discontinued (see 
Section 7.1.1), and the participant should receive appropriate follow-up medical care. 
8.2.8.3.Hepatitis B Testing and Monitoring  
Initial testing for hepatitis B virus (HBV) infection includes hepatitis B surface antigen (HBsAg) 
and antibody to hepatitis B core antigen (anti-HBc): 
 
If HBsAg is positive, the participant is excluded; 
 
If HBsAg is negative and anti-HBc is negative, the participant is not excluded; 
 
If HBsAg is negative and anti-HBc is positive, further testing for HBV DNA is required: 
o If the screening HBV DNA is positive, the participant is excluded; 
o If the screening HBV DNA is negative, the participant is not excluded. Repeat 
testing for HBV DNA is required at least every 3 months during the study (see 
the SoA [Section 1.3]), with temporary withholding or permanent discontinuation 
of study intervention if HBV DNA is positive, as described in Section 7.1.1. 
Management of enrolled participants with detectable HBV DNA during the study 
If HBV DNA is detected during the study, the study intervention will be temporarily withheld or 
permanently discontinued, and participants should receive appropriate follow-up medical care as 
described in Section 7. 
8.3. Adverse Events, Serious Adverse Events, and Product Complaints  
The definitions of the following events can be found in Appendix 10.3: 
Approved on 14 Feb 2023 GMT


CONFIDENTIAL 
Protocol I1F-IN-RHCZ (a) 
Page 64 
 Adverse events (AEs) 
 Serious adverse events (SAEs) 
 Product complaints (PCs) 
These events will be reported by the participant (or, when appropriate, by a caregiver, surrogate, 
or the participant’s legally authorized representative). 
The investigator and any qualified designees are responsible for detecting, documenting, and 
recording events that meet these definitions and remain responsible for following up events that 
are serious, considered related to the study intervention or study procedures, or that caused the 
participant to discontinue the study (see Section 7). 
After the initial report, the investigator is required to proactively follow each participant at 
subsequent visits/contacts. All SAEs and AEs of special interest (as defined in Section 8.3.3) will 
be followed until resolution, stabilization, the event is otherwise explained, or the participant is 
lost to follow-up (as defined in Section 7.3). For PCs, the investigator is responsible for ensuring 
that follow-up includes any supplemental investigations as indicated to elucidate the nature 
and/or causality. Further information on follow-up procedures is provided in Appendix 10.3. 
8.3.1. Timing and Mechanism for Collecting Events  
All SAEs will be collected from the signing of the ICF until the follow-up visit at the time points 
specified in the SoA (Section 1.3). 
All AEs will be collected from the signing of the ICF until participation in the study has ended. 
Adverse events that begin before the start of study intervention but after signing of the ICF will 
be recorded on the Adverse Event eCRF. 
Although all AEs after signing the ICF and Assent Form (as applicable) are recorded by the site 
in the eCRF/electronic data entry, SAE reporting to the Sponsor begins after the participant has 
signed the ICF and has received study intervention. However, if an SAE occurs after signing the 
ICF, but prior to receiving ixekizumab, it needs to be reported ONLY if it is considered 
reasonably possibly related to study procedures. 
All SAEs will be recorded and reported to the Sponsor or designee immediately and under no 
circumstance should this exceed 24 hours, as indicated in Appendix 10.3. The investigator will 
submit any updated SAE data to the Sponsor within 24 hours of it being available. Participants 
with a serious hepatic AE should have additional data collected using the electronic data entry. 
Investigators are not obligated to actively seek AEs or SAEs after conclusion of the study 
participation. However, if the investigator learns of any SAE, including a death, at any time after 
a participant has been discharged from the study, and he/she considers the event to be reasonably 
related to the study intervention or study participation, the investigator must promptly notify the 
Sponsor.

8.3.2. Pregnancy  
Collection of pregnancy information  
Male participants with partners who become pregnant 
 The investigator will attempt to collect pregnancy information on any male participant’s 
female partner who becomes pregnant while the male participant is in this study. This 
applies only to male participants who receive intervention. 
 After learning of a pregnancy in the female partner of a study participant, the investigator 
will: 
o obtain a consent to release information from the pregnant female partner directly; 
and  
o within 24 hours after obtaining this consent, will record pregnancy information on 
the appropriate form and submit it to the Sponsor.  
The female partner will also be followed to determine the outcome of the pregnancy. Information 
on the status of the mother and child will be forwarded to the Sponsor. Generally, the follow-up 
will be no longer than 6 to 8 weeks following the estimated delivery date. Any termination of the 
pregnancy will be reported regardless of gestational age, fetal status (presence or absence of 
anomalies), or indication for the procedure. 
Female participants who become pregnant 
The investigator will collect pregnancy information on any female participant who becomes pregnant 
while participating in this study. The initial information will be recorded on the appropriate form and 
submitted to the Sponsor within 24 hours of learning of a participant’s pregnancy. 
 The participant will be followed to determine the outcome of the pregnancy. The 
investigator will collect follow-up information on the participant and the neonate and the 
information will be forwarded to the Sponsor. Generally, follow-up will not be required 
for longer than 6 to 8 weeks beyond the estimated delivery date. Any termination of 
pregnancy will be reported, regardless of gestational age, fetal status (presence or absence 
of anomalies) or indication for the procedure. 
 While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy for medical reasons will be reported 
as an AE or SAE. 
 A spontaneous abortion (occurring at <20 weeks gestational age) or still birth (occurring at 
≥20 weeks gestational age) is always considered to be an SAE and will be reported as such. 
 Any post-study pregnancy-related SAE considered reasonably related to the study 
intervention by the investigator will be reported to the Sponsor as described in protocol 
Section 8.3.1. While the investigator is not obligated to actively seek this information in 
former study participants, he/she may learn of an SAE through spontaneous reporting. 
 Any female participant who becomes pregnant while participating in the study will 
discontinue study intervention. If the participant is discontinued from the study, follow 
the standard discontinuation process and continue directly to the follow-up phase. The 
follow-up on the pregnancy outcome should continue independent of intervention or 
study discontinuation.

8.3.3. Adverse Events of Special Interest  
The following adverse events of special interest (AESIs) will be used to determine the safety and 
tolerability of ixekizumab over the range of doses selected for this clinical study. 
Adverse events of special interests for ixekizumab are the following: 
 cytopenias (leukopenia, neutropenia, and thrombocytopenia), 
 liver function test changes/enzyme elevations (ALT, AST, bilirubin, and ALP), 
 infections, 
 injection-site reactions, 
 allergic reactions/hypersensitivities, 
 cerebro-cardiovascular events, 
 malignancies, 
 inflammatory bowel disease (IBD), and 
 depression.  
Sites will provide details on AEs as instructed on the eCRF. Investigators will also educate 
participants and/or caregivers about the symptoms of systemic allergic/hypersensitivity reactions 
and will provide instructions on the management and reporting of these reactions. Blood samples 
will be collected as soon as possible for any participant who experiences an AE of a potential 
systemic allergic/hypersensitivity reaction during the study, as judged by the investigator. These 
samples may be tested for antidrug antibodies (ADAs), other laboratory tests needed to elucidate 
the cause of the allergic/hypersensitivity reaction, and/or ixekizumab serum concentration.

described in this section. This section is a summary of the planned statistical analyses of the most 
important endpoints, including primary and key secondary endpoints. 
9.1. Statistical Hypotheses  
No statistical hypotheses testing is planned for this study.  
9.2. Analyses Populations  
The following analysis populations will be used; additional analysis populations will be specified 
in the SAP: 
Analysis Population 
Description 
PsO with No Active PsA – 
Modified Intent-to-Treat 
(mITT) Population 
Unless otherwise specified, efficacy and health outcomes analyses specific to 
psoriasis will be conducted on the PsO with No Active PsA - mITT 
population, defined as all enrolled participants with a psoriasis indication, who 
do not qualify for Active PsA and receive at least 1 dose of study treatment, 
even if the participant does not receive the correct treatment, or otherwise 
does not follow the protocol.   
Active PsA – mITT 
Population 
Unless otherwise specified, efficacy and health outcomes analyses specific to 
PsA will be conducted on the Active PsA mITT population, defined as all 
enrolled participants with an Active PsA indication who receive at least 1 dose 
of study treatment, even if the participant does not receive the correct 
treatment, or otherwise does not follow the protocol.  
Safety Population 
Safety analyses will be conducted on the safety population, defined as all 
enrolled participants who receive at least 1 dose of study treatment. 
Participants will be analyzed according to the treatment to which they are 
assigned.   
9.3 
Missing Data Imputation  
The following methods for imputation of missing data will be used:   
9.3.1 
General Nonresponder Imputation for Clinical Response  
Analysis of categorical efficacy and health outcomes variables will be assessed using a 
nonresponder imputation (NRI) method. Participants will be considered a nonresponder for the 
NRI analysis if they: 
 do not meet the clinical response criteria (e.g., ACR20, PASI75, PASI90, PASI100, 
sPGA [0,1]);  
 have missing clinical response data at a timepoint of interest (e.g., Week 12, Week 24);  
 discontinue study treatment at any time prior to a timepoint of interest for any reason; or 
 have no postbaseline observation.  
The NRI may be applied at any time point specified for analysis.

Study Participant Disposition and Characteristics  
9.4.1 Study Participant Disposition  
All participants who prematurely discontinue from the study treatment and/or from the study will 
be identified, and the extent of their participation in the study will be reported.   
Patient disposition will be summarized for each treatment period with reasons for 
discontinuation.   
9.4.2 Study Participant Characteristics  
Participant demographic characteristics and baseline clinical measures will be summarized 
overall. Baseline characteristics will include sex, age, age category, weight, body mass index, 
race, and other demographic characteristics as per the SoA (Section 1.3).   
9.4.3 Concomitant Therapy  
Previous and concomitant medications will be summarized for participants who enter treatment 
and will be presented by the World Health Organization (WHO) Anatomic Therapeutic Class 
(ATC) Level 4 and WHO preferred term (PT).   
9.4.4 Treatment Compliance  
Treatment compliance with investigational product will be summarized for participants who 
enter the treatment. A participant will be considered overall compliant for treatment if he/she is 
missing no more than 20% of the expected doses, does not miss 2 consecutive doses, and does 
not over-dose (i.e., take more injections at the same time point than specified in the protocol).   
Proportions of participants compliant by visit and overall will be reported. 
9.5 
 Statistical Analyses   
9.5.1. General Considerations  
Statistical analysis of this study will be the responsibility of Lilly. 
Unless otherwise specified, continuous data will be summarized in terms of the mean, standard 
deviation, minimum, maximum, median, and number of observations. Categorical data will be 
summarized as frequency counts and percentages. 
Baseline will be defined as the last non missing assessment recorded on or prior to the date of 
first injection for efficacy and health outcomes. In most cases, this will be the measure recorded 
at Week 0 (Visit 2). Change from baseline will be calculated as the visit value of interest minus 
the baseline value. For safety analyses using a baseline period, the baseline period is defined as 
the time from Visit 1 to the date/time of the first injection. 
Any change to the data analysis methods described in the protocol will require an amendment 
ONLY if it changes a principal feature of the protocol. Any other change to the data analysis 
methods described in the protocol, and the justification for making the change, will be described 
in the clinical study report (CSR). Additional exploratory analyses of the data will be conducted, 
as deemed appropriate.

9.5.5 
Safety Analyses  
Safety will be assessed by summarizing AEs, laboratory analytes and vital signs. Abnormal 
physical examinations and concomitant medications will be listed. The overall duration of 
treatment exposure will also be summarized.   
Safety data collected after study treatment discontinuation will be summarized separately. 
The categorical safety measures will be summarized with incidence rates. The absolute and mean 
change from baseline of the continuous safety measures will be summarized by visits.   
All safety analyses will be based on the safety population and will be summarized overall and by 
dosing regimen (Q2W/Q4W and Q4W/Q4W) as specified in Table RHCZ.6.1. 
Further details will be described in the SAP.   
9.5.5.1.Adverse Events  
Adverse events are classified based upon MedDRA. A TEAE is defined as an event that first 
occurred or worsened in severity after baseline and on or prior to the date of the last visit within 
the treatment period. Both the date/time of the event and the date/time of the injection are 
considered when determining TEAEs. TEAEs will be assigned to the treatment period in which 
they first occurred or worsened. A follow-up emergent adverse event (FEAE) is defined as an 
event that first occurred or worsened in severity after the date of Week 24 (Visit 6) or the ETV. 
For events that are gender specific, the denominator and computation of the percentage will 
include only participants from the given gender.   
A summary of AEs will be provided overall and by dosing regimen, including the number and 
percentage of participants who reported TEAEs, TEAEs by maximum severity, death, SAEs, 
TEAEs related to study intervention, discontinuations from the treatment due to an AE, and 
treatment-emergent AESIs: cytopenias, infections, injection-site reactions (ISRs), allergic 
reactions/hypersensitivities, cerebrocardiovascular events, MACE, malignancies, depression, 
IBD, ILD. TEAEs (all, by maximum severity, and possibly related to study intervention by the 
investigator), SAEs including deaths, AEs that lead to treatment discontinuation will be 
summarized by MedDRA system organ class (SOC) and PT.

Laboratory assessments will be presented as mean changes from baseline and as incidence of 
treatment-emergent abnormal, high, or low laboratory values (see below). Shift tables will be 
presented for selected parameters.   
 For categorical laboratory tests:  
o Treatment-emergent abnormal value = a change from normal at all baseline 
visits to abnormal at any time post baseline;  
 For continuous laboratory tests:  
o Treatment-emergent high value = a change from a value less than or equal to the 
high limit at all baseline visits to a value greater than the high limit at any time 
postbaseline; and 
o Treatment-emergent low value = a change from a value greater than or equal to 
the low limit at all baseline visits to a value less than the low limit at any time 
postbaseline. 
9.5.5.3.Vital Signs  
Vital signs will be presented as mean changes from baseline and as incidence of treatment-
emergent high or low values (see below) and will be summarized both pre- and post dose at 
Week 0 (Visit 2) and postbaseline visits, as applicable.   
 For treatment-emergent high and low:   
o A treatment-emergent high result is defined as a change from a value less than 
or equal to the high limit at baseline to a value greater than the high limit at 
any time that meets the specified change criteria during the treatment period; 
o 
A treatment-emergent low result is defined as a change from a value 
greater than or equal to the low limit at baseline to a value less than the low 
limit at any time that meets the specified change criteria during the treatment 
period.

● The medical record must include a statement that written informed consent was obtained 
before the participant was entered in the study and the date the written consent was 
obtained. The authorized person obtaining the informed consent must also sign the ICF. 
● Participants must be re-consented to the most current version of the ICF(s) during their 
participation in the study. 
● If a participant reaches the age of legal consent during the study, an ICF must be obtained 
from the participant for his or her continued participation in the study. 
● A copy of the ICF(s) must be provided to the participant or the participant’s legally 
authorized representative and is kept on file. 
10.1.4 Data Protection  
● Participants will be assigned a unique identifier by the Sponsor. Any participant records, 
datasets, or tissue samples that are transferred to the Sponsor will contain the identifier 
only; participant names or any information which would make the participant identifiable 
will not be transferred. 
● The participant must be informed that the participant’s personal study-related data will be 
used by the Sponsor in accordance with local data protection law. The level of disclosure 
must also be explained to the participant who will be required to give consent for their 
data to be used as described in the informed consent.  
● The participant must be informed that their medical records may be examined by Clinical 
Quality Assurance auditors or other authorized personnel appointed by the Sponsor, by 
appropriate IRB/IEC members, and by inspectors from regulatory authorities. 
● The Sponsor has processes in place to ensure data protection, information security and 
data integrity. These processes include appropriate contingency plan(s) for appropriate 
and timely response in the event of a data security breach. 
10.1.5 Data Quality Assurance  
● All participant data relating to the study will be recorded on electronic CRFs unless 
transmitted to the Sponsor or designee electronically (e.g., laboratory data). The

transcribed into the CRF by authorized site personnel are accurate, complete, and 
verifiable from source documents; that the safety and rights of participants are being 
protected; and that the study is being conducted in accordance with the currently 
approved protocol and any other study agreements, ICH GCP, and all applicable 
regulatory requirements. 
● Records and documents, including signed ICFs, pertaining to the conduct of this study 
must be retained by the investigator for the time period outlined in the Clinical Trial 
Agreement (CTA) unless local regulations or institutional policies require a longer 
retention period. No records may be destroyed during the retention period without the 
written approval of the Sponsor. No records may be transferred to another location or 
party without written notification to the Sponsor. 
● In addition, Sponsor or its representatives will periodically check a sample of the 
participant data recorded against source documents at the study site. The study may be 
audited by Sponsor or its representatives, and/or regulatory agencies at any time. 
Investigators will be given notice before an audit occurs. 
Data Capture System 
The investigator is responsible for ensuring the accuracy, completeness, legibility, and timeliness 
of the data reported to the Sponsor. 
An electronic data capture system (EDC) will be used in this study for the collection of CRF 
data. The investigator maintains a separate source for the data entered by the investigator or 
designee into the Sponsor-provided EDC system. The investigator is responsible for the 
identification of any data to be considered source and for the confirmation that data reported are 
accurate and complete by signing the CRF. 
Data collected via the Sponsor-provided data capture systems will be stored at third parties. The 
investigator will have continuous access to the data during the study and until decommissioning 
of the EDC systems. Prior to decommissioning, the investigator will receive an archival copy of 
pertinent data for retention.

10.3 Appendix 3: Adverse Events and Serious Adverse Events: Definitions 
and Procedures for Recording, Evaluating, Follow-up, and Reporting  
10.3.1 Definition of AE  
AE Definition 
An AE is any untoward medical occurrence in a participant or clinical study participant, 
temporally associated with the use of study intervention, whether or not considered related to 
the study intervention. 
 NOTE: An AE can therefore be any unfavourable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally 
associated with the use of study intervention. 
 
Events Meeting the AE Definition 
 Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or 
other safety assessments (e.g., ECG, radiological scans, vital signs measurements), 
including those that worsen from baseline, considered clinically significant in the 
medical and scientific judgment of the investigator (i.e., not related to progression of 
underlying disease). 
 Exacerbation of a chronic or intermittent preexisting condition including either an 
increase in frequency and/or intensity of the condition. 
 New conditions detected or diagnosed after study intervention administration even 
though it may have been present before the start of the study. 
 Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction. 
 Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
intervention or a concomitant medication. Overdose per se will not be reported as an 
AE/SAE unless it is an intentional overdose taken with possible suicidal/self-harming 
intent. Such overdose should be reported regardless of sequelae. 
 “Lack of efficacy” or “failure of expected pharmacological action,” per se, will not be 
reported as an AE or SAE. Such instances will be captured in the efficacy assessments. 
However, the signs, symptoms, and/or clinical sequelae resulting from lack of efficacy 
will be reported as AE or SAE if they fulfill the definition of an AE or SAE. 
 
Approved on 14 Feb 2023 GMT


CONFIDENTIAL 
Protocol I1F-IN-RHCZ (a) 
Page 81 
Events NOT Meeting the AE Definition 
 Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments which are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the participant’s condition. 
 The disease/disorder being studied or expected progression, signs, or symptoms of the 
disease/disorder being studied, unless more severe than expected for the participant’s 
condition. 
 Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that leads to 
the procedure is the AE. 
 Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital). 
 Anticipated day-to-day fluctuations of preexisting disease(s) or condition(s) present or 
detected at the start of the study that do not worsen. 
10.3.2 Definition of SAE  
If an event is not an AE per definition above, then it cannot be an SAE even if serious conditions 
are met (e.g., hospitalization for signs/symptoms of the disease under study, death due to 
progression of disease). 
 
An SAE is defined as any untoward medical occurrence that, at any dose, meets one or 
more of the criteria listed: 
a. Results in death 
b. Is life-threatening 
The term life-threatening in the definition of serious refers to an event in which the participant 
was at risk of death at the time of the event. It does not refer to an event, which hypothetically 
might have caused death, if it were more severe. 
c. 
Requires inpatient hospitalization or prolongation of existing hospitalization 
 In general, hospitalization signifies that the participant has been admitted to hospital or 
emergency ward (usually involving at least an overnight stay) for observation and/or 
treatment that would not have been appropriate in the physician’s office or outpatient 
setting. Complications that occur during hospitalization are AEs. If a complication 
prolongs hospitalization or fulfills any other serious criteria, the event is serious. When 
in doubt as to whether hospitalization occurred or was necessary, the AE should be 
considered serious. 
 Hospitalization for elective treatment of a preexisting condition that did not worsen 
from baseline is not considered an AE. 
 
Approved on 14 Feb 2023 GMT


CONFIDENTIAL 
Protocol I1F-IN-RHCZ (a) 
Page 82 
d. Results in persistent disability/incapacity 
 The term disability means a substantial disruption of a person’s ability to conduct 
normal life functions. 
 This definition is not intended to include experiences of relatively minor medical 
significance such as uncomplicated headache, nausea, vomiting, diarrhea, influenza, 
and accidental trauma (e.g., sprained ankle) which may interfere with or prevent 
everyday life functions but do not constitute a substantial disruption. 
e. 
Is a congenital anomaly/birth defect 
 Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAEs. 
f. 
Other situations: 
 Medical or scientific judgment should be exercised by the investigator in deciding 
whether SAE reporting is appropriate in other situations such as important medical 
events that may not be immediately life-threatening or result in death or hospitalization 
but may jeopardize the participant or may require medical or surgical intervention to 
prevent one of the other outcomes listed in the above definition. These events should 
usually be considered serious. 
 
Examples of such events include invasive or malignant cancers, intensive treatment in 
an emergency room or at home for allergic bronchospasm, blood dyscrasias or 
convulsions that do not result in hospitalization, or development of drug dependency or 
drug abuse.  
10.3.3 Definition of Product Complaints  
Product Complaint 
 A PC is any written, electronic, or oral communication that alleges deficiencies related 
to the identity, quality, durability, reliability, safety, effectiveness or performance of a 
study intervention. When the ability to use the study intervention safely is impacted, 
the following are also PCs: 
o Deficiencies in labeling information, and 
o Use errors for device or drug-device combination products due to ergonomic 
design elements of the product. 
 Product complaints related to study interventions used in clinical trials are collected in 
order to ensure the safety of participants, monitor quality, and to facilitate process and 
product improvements. 
 Investigators will instruct participants to contact the site as soon as possible if he/she 
has a PC or problem with the study intervention so that the situation can be assessed. 
 An event may meet the definition of both a PC and an AE/SAE. In such cases, it 
should be reported as both a PC and as an AE/SAE.

Protocol I1F-IN-RHCZ (a) 
Page 83 
10.3.4 Recording and Follow-Up of AE and/or SAE and Product Complaints  
AE, SAE, and Product Complaint Recording 
 When an AE/SAE/PC occurs, it is the responsibility of the investigator to review all 
documentation (e.g., hospital progress notes, laboratory reports, and diagnostics 
reports) related to the event. 
 The investigator will then record all relevant AE/SAE/PC information in the 
participant’s medical records, in accordance with the investigator’s normal clinical 
practice. AE/SAE information is reported on the appropriate CRF page and PC 
information is reported on the Product Complaint Form. 
Note: An event may meet the definition of both a PC and an AE/SAE. In such cases, it 
should be reported as both a PC and as an AE/SAE. 
 It is not acceptable for the investigator to send photocopies of the participant’s medical 
records to Sponsor or designee in lieu of completion of the CRF page for AE/SAE and 
the Product Complaint Form for PCs. 
 There may be instances when copies of medical records for certain cases are requested 
by Sponsor or designee. In this case, all participant identifiers, with the exception of 
the participant number, will be redacted on the copies of the medical records before 
submission to Sponsor or designee. 
 The investigator will attempt to establish a diagnosis of the event based on signs, 
symptoms, and/or other clinical information. Whenever possible, the diagnosis (not the 
individual signs/symptoms) will be documented as the AE/SAE. 
Assessment of Intensity 
The investigator will make an assessment of intensity for each AE and SAE reported during 
the study and assign it to one of the following categories:  
 Mild: A type of AE that is usually transient and may require only minimal treatment or 
therapeutic intervention. The event does not generally interfere with usual activities of 
daily living. 
 Moderate: A type of AE that is usually alleviated with additional specific therapeutic 
intervention. The event interferes with usual activities of daily living, causing 
discomfort but poses no significant or permanent risk of harm to the research 
participant. 
 Severe: A type of AE that interrupts usual activities of daily living, or significantly 
affects clinical status, or may require intensive therapeutic intervention. An AE that is 
assessed as severe should not be confused with an SAE. Severe is a category utilized 
for rating the intensity of an event; and both AEs and SAEs can be assessed as severe. 
An event is defined as “serious” when it meets at least one of the predefined outcomes 
as described in the definition of an SAE, NOT when it is rated as severe.

Protocol I1F-IN-RHCZ (a) 
Page 84 
Assessment of Causality 
 The investigator is obligated to assess the relationship between study intervention and 
each occurrence of each AE/SAE. The investigator will use clinical judgment to 
determine the relationship. 
 A “reasonable possibility” of a relationship conveys that there are facts, evidence, 
and/or arguments to suggest a causal relationship, rather than a relationship cannot be 
ruled out. 
 Alternative causes, such as underlying disease(s), concomitant therapy, and other risk 
factors, as well as the temporal relationship of the event to study intervention 
administration will be considered and investigated. 
 The investigator will also consult the IB in his/her assessment. 
 For each AE/SAE, the investigator must document in the medical notes that he/she has 
reviewed the AE/SAE and has provided an assessment of causality. 
 There may be situations in which an SAE has occurred and the investigator has 
minimal information to include in the initial report to Sponsor or designee. However, it 
is very important that the investigator always make an assessment of causality for 
every event before the initial transmission of the SAE data to Sponsor or designee. 
 The investigator may change their opinion of causality in light of follow-up 
information and send an SAE follow-up report with the updated causality assessment. 
 The causality assessment is one of the criteria used when determining regulatory 
reporting requirements. 
Follow-up of AEs and SAEs 
 The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as medically indicated or as requested by Sponsor or 
designee to elucidate the nature and/or causality of the AE or SAE as fully as possible. 
This may include additional laboratory tests or investigations, histopathological 
examinations, or consultation with other healthcare professionals. 
 If a participant dies during participation in the study or during a recognized follow-up 
period, the investigator will provide Sponsor or designee with a copy of any 
postmortem findings including histopathology. 
 New or updated information will be recorded in the originally completed eCRF. 
 The investigator will submit any updated SAE data to the Sponsor or designee within 
24 hours of receipt of the information.

10.3.5 Reporting of SAEs  
SAE Reporting via an Electronic Data Collection Tool 
 The primary mechanism for reporting an SAE will be the electronic data collection 
tool. 
 If the electronic system is unavailable or if a pregnancy is reported, then the site will 
use the paper SAE or pregnancy data collection tool (see next section) to report the 
event within 24 hours. 
 The site will enter the SAE data into the electronic system as soon as it becomes 
available. 
 After the study is completed at a given site, the electronic data collection tool will be 
taken offline to prevent the entry of new data or changes to existing data. 
 If a site receives a report of a new SAE from a study participant or receives updated 
data on a previously reported SAE after the electronic data collection tool has been 
taken offline, then the site can report this information on a paper SAE form (see next 
section) or to the Sponsor or designee by telephone. 
 Contacts for SAE reporting can be found in the site training documents. 
SAE Reporting via Paper Form 
 In the event the electronic system is unavailable, facsimile transmission of the SAE 
paper CRF is the preferred method to transmit this information to the Sponsor. 
 Initial notification via telephone does not replace the need for the investigator to 
complete and sign the SAE CRF pages within the designated reporting time frames. 
 Contacts for SAE reporting can be found in the site training documents 
10.3.6 Regulatory Reporting Requirements  
SAE Regulatory Reporting 
 Prompt notification by the investigator to the Sponsor of an SAE is essential so that 
legal obligations and ethical responsibilities towards the safety of participants and the 
safety of a study intervention under clinical investigation are met. 
● The Sponsor has a legal responsibility to notify both the local regulatory 
authority and other regulatory agencies about the safety of a study intervention 
under clinical investigation. The Sponsor will comply with country-specific 
regulatory requirements relating to safety reporting to the regulatory authority, 
IRB/IEC, and investigators. 
● An investigator who receives an investigator safety report describing an SAE or 
other specific safety information (e.g., summary or listing of SAEs) from the 
Sponsor will review and then file it along with the Investigator’s Brochure and 
will notify the IRB/IEC, if appropriate, according to local requirements.

10.4 Appendix 4: Contraceptive and Barrier Guidance  
10.4.1 Definitions  
Woman of Childbearing Potential (WOCBP) 
A woman is considered fertile following menarche and until becoming post-menopausal unless 
permanently sterile (see below). 
If fertility is unclear (e.g., amenorrhea in adolescents or athletes) and a menstrual cycle cannot be 
confirmed before first dose of study intervention, additional evaluation should be considered. 
Women in the following categories are not considered WOCBP: 
 Premenarchal 
 Premenopausal female with 1 of the following: 
o Documented hysterectomy 
o Documented bilateral salpingectomy 
o Documented bilateral oophorectomy 
 
For individuals with permanent infertility due to an alternate medical cause other than the 
above, (e.g., Mullerian agenesis, androgen insensitivity), investigator discretion should be 
applied to determining study entry. 
 
Note: Documentation can come from the site personnel’s: review of the participant’s medical 
records, medical examination, or medical history interview. 
A postmenopausal female is defined as women with: 
o At least 6 weeks post-surgical bilateral oophorectomy with or without 
hysterectomy, confirmed by operative note. 
OR 
o With spontaneous amenorrhea for at least 12 months, not induced by a medical 
condition such as anorexia nervosa and not taking medications during the 
amenorrhea (e.g., oral contraceptives, hormones, gonadotropin releasing 
hormone, anti-estrogens, selective estrogen receptor modulators (SERMs), or 
chemotherapy that induced the amenorrhea. And if age ≤50, has an FSH of 
≥40 mIU/mL and estradiol of ≤ 30 pg/mL.

10.4.2 Contraception Guidance  
Male participants with partners who become pregnant 
The investigator will attempt to collect pregnancy information on a male participant’s female 
partner who becomes pregnant while the male participant is in this study.  
After obtaining the necessary signed informed consent and/or assent from the pregnant female 
partner directly, the investigator will record pregnancy information on the appropriate form and 
submit it to the Sponsor within 24 hours of learning of the partner’s pregnancy. The female 
partner will also be followed up to determine the outcome of the pregnancy. Information on the 
status of the mother and child will be forwarded to the Sponsor. Generally, the follow-up will be 
no longer than 6 to 8 weeks following the estimated delivery date. Any termination of the 
pregnancy will be reported, including fetal status (presence or absence of anomalies) or 
indication for the procedure. 
Female participants who become pregnant 
The investigator will collect pregnancy information on any female participant who becomes 
pregnant while participating in this study. The initial information will be recorded on the 
appropriate form and submitted to the Sponsor within 24 hours of learning of a participant’s 
pregnancy. 
The participant will be followed up to determine the outcome of the pregnancy. The investigator 
will collect follow-up information on the participant and the neonate, and the information will be 
forwarded to the Sponsor. Generally, follow-up will not be required for longer than 6 to 8 weeks 
beyond the estimated delivery date. Any termination of pregnancy will be reported, including 
fetal status (presence or absence of anomalies) or indication for the procedure. 
While pregnancy itself is not considered to be an AE or SAE, any pregnancy complication or 
elective termination of a pregnancy for medical reasons will be reported as an AE or SAE. 
A spontaneous abortion (occurring at <20 weeks gestational age) or still birth (occurring at 
≥20 weeks gestational age) is always considered to be an SAE and will be reported as such. 
Any post-study pregnancy-related SAE considered reasonably related to the study intervention 
by the investigator will be reported to the Sponsor. While the investigator is not obligated to 
actively seek this information in former study participants, the investigator may learn of an SAE 
through spontaneous reporting. 
Any female participant who becomes pregnant while participating in the study will permanently 
discontinue the study intervention (see Section 7.1.1).

Protocol RHCZ CASPAR Criteria  
CASPAR Criteria 
The CASPAR criteria for psoriatic arthritis consist of inflammatory articular disease (joint, 
spine, or entheseal) with ≥3 points from the following 5 categories.  
 Evidence of current psoriasis, a personal history of psoriasis, or a family history of 
psoriasis (2 points)  
o Current psoriasis is defined as psoriatic skin or scalp disease present today as 
judged by a rheumatologist or dermatologist.†  
o A personal history of psoriasis is defined as a history of psoriasis that may be 
obtained from a participant, family physician, dermatologist, rheumatologist, or 
other qualified healthcare provider.  
o A family history of psoriasis is defined as a history of psoriasis in a first- or 
second-degree relative according to participant report. 
 Typical psoriatic nail dystrophy including onycholysis, pitting, and hyperkeratosis 
observed on current physical examination (1 point)  
 A negative test result for the presence of rheumatoid factor by any method except latex 
(1 point)  
 Either current dactylitis, defined as swelling of an entire digit, or a history of dactylitis 
recorded by a rheumatologist (1 point)  
 Radiographic evidence of juxta-articular new bone formation appearing as ill-defined 
ossification near joint margins (but excluding osteophyte formation) on plain radiographs 
of the hand or foot (1 point)  
† Current psoriasis is assigned a score of 2; all other features are assigned a score of 1.

Study Rationale 
The rationale for this post-approval Phase 4 ixekizumab study is to evaluate the safety and 
tolerability when ixekizumab is administered to participants in India with moderate-to-severe 
plaque psoriasis (PsO) and/or active psoriatic arthritis (PsA). Participants with 
moderate-to-severe plaque psoriasis are defined as those with PASI ≥12, sPGA ≥3, and BSA 
≥10%. … 
 
2.2. 
Background 
… 
More information about the known and expected benefits, risks, and reasonably anticipated AEs 
of ixekizumab may be found in the Copellor® package insert. Information on AEs expected to be 
related to the investigational product may be found in Section 6.27 (Development Core Safety 
Information [DCSI]) of the Investigator’s Brochure (IB). Information on SAEs that are expected 
in the study population (independent of drug exposure) and that will be assessed by the Sponsor 
in aggregate, periodically during the course of the study, may be found in Section 56 (Effects in 
Humans) of the Copellor package insertIB. 
 
2.3. 
Benefit/Risk Assessment 
Ixekizumab has been demonstrated to be safe and effective for the treatment of participants with 
moderate-to-severe chronic PsO and/or active PsA. The risk profile for participants within this 
study is anticipated to be consistent with the known safety experience for ixekizumab.

4.1. 
Overall Design 
Study RHCZ is a prospective, multicenter, open-label, single-arm, Phase 4 study with 4 study 
periods assessing outcomes in terms of AEs and SAEs with ixekizumab when used in 
participants aged ≥18 years for PsO and PsA in Indian population (Section 1.2). 
The following treatment will be assessed in this study for PsO participants with no active PsA 
and PsA participants who meet criteria for moderate-to-severe PsO: 
 Ixekizumab: 80-mg subcutaneous (SC) injection. 
o At Week 0, 160-mg starting dose (two 80-mg injections), followed by 80 mg 
Q2W from Weeks 2 through 12, and then followed by 80 mg Q4W thereafter 
(i.e., at Weeks 16 and 20). 
… 
 
4.1.1. 
Screening Period (Period 1) 
… 
All inclusion and exclusion criteria are provided in Sections 5.1 and 5.2, respectively. Screening 
procedures (including complete medical history, and demographics, and substance use) will be 
performed according to the SoA (Section 1.3). At Visit 1, a QuantiFERON®-TB Gold test assay 
may be performed by a Lilly-designated or local laboratory (Section 8.2.78.2.6). 
Participants who test positive for latent tuberculosis (TB) at screening may be re-screened once 
following appropriate treatment, as described in Section 8.2.78.2.6.

Post-Treatment Follow-Up Period (Period 4) 
… 
If, at Visit 801, a participant’s neutrophil count is ≥1500 cells/L or greater than or equal to the 
participant’s baseline neutrophil count, the participant’s participation in the study will be 
considered complete unless the investigator determines additional follow-up may be necessary. 
An additional study visit (Visit 802) 4 8 weeks after Visit 801 may be required for appropriate 
participant management (described below). 
… 
 Participants with concurrent infection: If there is a concurrent infection that requires 
systemic anti-infective therapy, the participant should receive appropriate medical 
care and a repeat test for neutrophil count should be performed at least Q4W (or 
sooner as appropriate) until resolution of infection. Upon resolution of infection, the 
neutrophil count should be monitored using the required study visits in the Post-
Treatment Follow-Up Period (Period 4) design at Visits 801 (4 weeks after resolution 
of infection) and 802 (4 8 weeks after Visit 801); additional visits may be required 
depending on the degree of neutropenia.

4.2. 
Scientific Rationale for Study Design 
This study will examine the effect of ixekizumab on participants with moderate-to-severe PsO 
and/or PsA. 
During the Induction Dosing Period (Period 2), participant’s safety and efficacy will be assessed 
at 80 mg Q2W dose for the participants with PsO and PsA participants who meet criteria for 
moderate-to-severe PsO. In PsA participants who do not meet criteria of moderate-to-severe 
PsO, participant’s safety and efficacy will be assessed at 80 mg Q4W dose. During the 
maintenance Period (Period 3), ixekizumab 80 mg Q4W will be studied. 
…

The DAS28-CRP is a measure of disease activity in 28 joints that consists of a composite 
numerical score utilizing the following variables: TJC, SJC, hs-CRP (measured in mg/L), and 
Patient’s General Assessment recorded by participants on a 0 to 100 mm VAS. 
For DAS28-CRP, the 28 joints to be examined and assessed as tender or not tender for TJC and 
as swollen or not swollen for SJC are a subset of those assessed for the TJC and SJC, and include 
14 joints on each side of the participant’s body: the 2 shoulders, the 2 elbows, the 2 wrists, the 
10 metacarpophalangeal joints, the 2 interphalangeal joints of the thumb, the 8 proximal 
interphalangeal joints, and the 2 knees (Smolen et al. 1995). The following equation will be used 
to calculate the DAS28-CRP (Vander Cruyssen et al. 2005):

Patient Global Assessment of Disease Activity VAS  
The participant’s overall assessment of his/her PsO and PsA activity will be recorded using the 
100 mm horizontal VAS where the left end represents no disease activity, and the right end 
represents extreme disease activity.

Physician’s Global Assessment of Disease Activity Visual Analog Scale 
The Investigator will be asked to give an overall assessment of the severity of the participant’s 
current PsO and PsA activity using a 100 mm horizontal VAS, where 0 represents no disease 
activity and 100 represents extremely active disease. The investigator making the assessment 
must be a rheumatologist or medically qualified physician. The same assessor should preferably 
perform the Physician’s Global Assessment of Disease Activity VAS for a given participant 
particularly during the Induction Dosing Period (Period 2) to minimize interobserver variation. 
 
8.2.4. 
Evaluation of Disease Relapse 
Patients will be assessed for the presence or absence of relapse at screening based on the 
following definitions: 
a. Assessment of relapse for psoriasis participants:  
Relapse is defined as worsening of psoriasis from the previous routine medical visit by 50% 
PASI or 1% BSA (in each case if sPGA ≥3) (Tian and Lai 2016). 
If PASI, BSA, or sPGA are not available in medical charts, relapse of psoriasis is defined as 
any worsening of psoriatic lesions that would, if persistent, in most cases require initiation or 
change of systemic therapy for psoriasis. 
During the study period, relapse with ixekizumab would be defined as worsening of psoriasis 
from the previous visit by 50% PASI or 1% BSA or sPGA ≥3. 
Relapse present based on the above definition: Yes/No 
Following details will be collected in addition in all PsO participants: 
 Duration of the psoriasis since diagnosis: 
 Duration of the psoriatic arthritis since diagnosis: 
 Prior systemic medications used for psoriasis:  
o Name of the drug and dose 
o Start date 
o End date 
 Prior systemic medications used for psoriatic arthritis:  
o Name of the drug and dose 
o Start date 
o End date 
b. Assessment of relapse for psoriatic arthritis participants:  
Relapse is defined as an increase in PsA disease activity from the previous routine medical 
either DAS28(ESR) >2.6 and DAS28(ESR) increase >0.6 or DAS28(ESR) increase ≥1.2, 
irrespective of absolute DAS28(ESR) (Emery et al. 2020; Helliwell et al. 2021). 
If DAS-28 CRP is not available in medical charts, relapse of PsA is defined as any increase 
in disease activity that would, if persistent, in most cases require initiation or change of 
systemic therapy for PsA.

Trial design
4.1 
Design overview
Study RHCZ is a prospective, multicenter, open-label, single-arm, Phase 4 study with 
4 study periods assessing outcomes in terms of AEs and SAEs with Ixekizumab when 
used in participants aged ≥18 years for PsO and PsA in an Indian population. 
The study will consist of 4 periods: 
4.1.1 
Screening Period (Period 1; 5 to 28 days) 

The duration of the Screening Period will be 5 to 28 days before the Induction
Dosing Period (Period 2) and consists of 1 screening visit (Visit 1) to assess
participant eligibility.
4.1.2 
Induction Dosing Period (Period 2; 12 weeks)

The Induction Dosing Period (Period 2) will occur from Week 0 (baseline; Visit
2) to Week 12 (Visit 5).

At Week 0, a 160-mg starting dose of Ixekizumab (two 80-mg injections)
will be assigned, followed by Ixekizumab 80 mg Q2W from Weeks 2
through 12 to PsO participants with no active PsA and PsA participants who
meet criteria of moderate-to-severe PsO

At Week 0, a 160-mg starting dose of Ixekizumab (two 80-mg injections)
will be assigned, followed by Ixekizumab 80 mg Q4W from Weeks 4
through 12 (i.e., at week 4, 8, 12) to PsA without PsO participants.
4.1.3 
Maintenance Period (Period 3; 12 weeks)

The Maintenance Period (Period 3) will occur from Week 12 (Visit 5) up to
Week 24 (Visit 6).

Ixekizumab 80 mg Q4W (i.e., at Weeks 16 and 20) will be assigned to all the
participants. Refer to Protocol Section 6.1, Table RHCZ.6.1, and Table
RHCZ.6.2 for a full description of treatment groups and dosing during Period 3.
4.1.4 
Post-Treatment Follow-Up Period (Period 4)

All participants receiving at least 1 dose of study intervention will enter the Post-
Treatment Follow-Up Period (Period 4) for a minimum of 4 weeks, beginning
after their last regularly scheduled visit at Week 24 (or the date of their ETV).

Participants discontinuing from the study intervention who have received at
least 1 dose of study intervention will continue to the ETV prior to entering to
the Post-Treatment Follow-Up period.

Required study visits should occur at 4 weeks (Visit 801) after the last regularly
scheduled visit at Week 24 (or the date of the participant’s ETV), except for
participants with a concurrent infection that requires systemic anti-infective
therapy (as described in protocol section 4.1.4).

Schema 
a.
For PsO participants with no active PsA and PsA participants who meet criteria for moderate-to-
severe PsO, Ixekizumab prefilled syringes will be administered by two 80-mg SC injections at
Week 0, then one 80-mg SC injection Q2W at Weeks 2, 4, 6, 8, and 10 will be administered.
Starting from Week 12, 80 mg Ixekizumab will be administered by one 80-mg SC injection Q4W
(i.e., at Weeks 12, 16, and 20). The last dose will be administered at Week 20.
b.
For PsA participants who do not meet criteria for moderate-to-severe PsO, Ixekizumab prefilled
syringes will be administered by two 80-mg SC injections at Week 0, then one 80-mg SC injection
Q4W at Weeks 4, 8, 12, 16, and 20 will be administered. The last dose will be administered at
Week 20.
Note: When the dosing is scheduled at home, the participants or care givers >will administer the 
provided Ixekizumab prefilled syringes. 
4.3 
Schedule of events 
Refer Protocol Section 1.3 “Table RHCZ.1.1. Schedule of Activities”. 
4.4 
Sample size determination: 
No formal sample size calculation was done for this study. 
Approximately, 250 participants (PsO: 150 participants and PsA: 100 participants) was 
planned to be enrolled into this study, and assuming discontinuations of approximately 
10%, approximately 225 participants should complete the 24-week period of treatment.

Analysis populations
Agreement and authorization of participants included/excluded from each analysis 
population will be reached prior to final database hard lock. Sponsor will supply a list 
of all participants to be excluded from the relevant analysis populations, including the 
reason(s) for exclusion from the analysis populations. Number and percentage of 
patients in each analysis population will be provided along with a corresponding by-
patient listing. 
6.1 
Enrolled Analysis Population (ENRL) 
6.2 
All participants who sign informed consent form. PsO with no Active PsA– 
Modified Intent-to-Treat (mITT) Population 
Unless otherwise specified, efficacy and health outcomes analyses specific to 
psoriasis will be conducted on the PsO with No Active PsA- mITT population, defined 
as all enrolled participants with a psoriasis indication, who do not qualify for Active PsA 
and receives at least 1 dose of study treatment, even if the participant does not receive 
the correct treatment, or otherwise does not follow the protocol. 
6.3 
Active PsA – Modified Intent-to-Treat (mITT) Population 
Unless otherwise specified, efficacy and health outcomes analyses specific to PsA will 
be conducted on the Active PsA mITT population, defined as all enrolled participants 
with an Active PsA indication who receives at least 1 dose of study treatment, even if 
the participant does not receive the correct treatment, or otherwise does not follow the 
protocol. 
6.4

General considerations
7.1 
Visit and date conventions

Visit day will be calculated from the reference start date which will be used to
present start/stop day of assessments and events. The reference start date is
defined as the date of first study treatment administration.
The following conventions will be used for visit references:
Visit day =  date of visit –  reference start date
Visit week = visit day
7
,
rounding up to next whole number 

If event date<reference start date then event day= (date of event - reference
start date), Otherwise if event date is on or after reference start date then
event day= (date of event - reference start date) +1
No visit windowing (i.e., remapping of visits based on visit windows) will be performed 
for this trial. The assigned nominal visit will be used for by-visit summaries. 
Unscheduled measurements will not be included in by-visit summaries. Data collected 
at early termination visits will be mapped to the next planned visit number for that 
patient. 
7.2 
Baseline 
Baseline will be defined as the last non-missing assessment recorded on or prior to 
the date of first injection for efficacy and health outcomes. In most cases, this will be 
the measure recorded at Week 0 (Visit 2). For safety analyses using a baseline period, 
the baseline period is defined as the time from Visit 1 to the date/time of the first 
injection. 
7.3 
Stratifications 
Unless otherwise specified, for analysis purposes, trial participants may be sub-
classified based on dosing regimen into the following stratification levels, where 
applicable: 

PsO dosing regimen Q2W/Q4W
o
Ixekizumab for [PsO]
o
Ixekizumab for [PsA with PsO]

PsA dosing regimen Q4W/Q4W
o
Ixekizumab for [PsA without PsO]
7.4 
Common calculations 
For quantitative measurements, change from baseline will be calculated as the post-
baseline visit value of interest minus the baseline value, where Baseline will be defined 
as the last non-missing assessment recorded on or prior to the date of first injection 
for efficacy and health outcomes. In most cases, this will be the measure recorded at 
Week 0 (Visit 2). For safety analyses using a baseline period, the baseline period is 
defined as the time from Visit 1 to the date/time of the first injection. If the baseline 
value is missing for a particular variable, then the change from baseline and the 
percent improvement from baseline will not be calculated. 
  


I1F-IN-RHCZ 
Statistical Analysis Plan 
15-Nov-24
Version 3.0 
CONFIDENTIAL 
Page 18 of 60 
Change from baseline will be calculated as the postbaseline value minus the baseline 
value. Percent change from baseline is defined as: 100 times the change from baseline 
divided by baseline. Percent improvement from baseline is calculated as: the positive 
percent change from baseline if a higher value postbaseline means improvement from 
baseline; and as the negative percent change from baseline if a lower value 
postbaseline means improvement from baseline. If the baseline value is missing for a 
particular variable, then the change from baseline and the percent improvement from 
baseline will not be calculated. 
7.5 
Software 
All analyses will be conducted using SAS® Version 9.4 or later.

Statistical considerations
8.1 
Multicenter studies 
The study will be conducted in multiple sites. 
8.2 
Missing data 
8.2.1 
Non-Responder Imputation (NRI) method 
Analysis of categorical efficacy and health outcomes variables will be assessed using 
a non-responder imputation (NRI) method. Participants will be considered a non-
responder for the NRI analysis if they: 

Do not meet the clinical response criteria (e.g., ACR20, PASI75, PASI90, PASI
100, sPGA [0,1]);

have missing clinical response data at a timepoint of interest (e.g., Week 12,
Week 24);

discontinue study treatment at any time prior to a timepoint of interest for any
reason; or

have no postbaseline observation
The NRI may be applied at any time point specified for analysis. 
8.2.2 
Last Observation Carry Forward (LOCF) 
The LOCF method will be used for the analysis of continuous endpoints (unless 
otherwise stated). The last non-missing postbaseline observation on or prior to the 
missed visit within the same period will be carried forward to subsequent time points 
for evaluation. Patients without at least 1 postbaseline observation will not be included 
for evaluation. 
8.2.3 
Modified Baseline Observation Carry Forward (mBOCF) 
Missing data for continuous efficacy and health outcomes variables will be imputed 
using a mBOCF method. For patients discontinuing investigational product due to an 
AE, including death, the baseline observation will be carried forward to the 
corresponding primary endpoint for evaluation. That is the participant, under this 
method, is defined as reverting back-to-back to baseline regardless of any continuing 
efficacy benefits, they may still have received after the event. 
8.3 
As observed data 
For all binary and continuous endpoints, a summary based on observed data at each 
postbaseline visit will be provided. For “as observed” analysis, only data from 
completers at the visit are relevant and therefore, the analysis does not need to deal 
with missing data. 
8.4 
Output presentation 
The templates provided in the separate output templates document describe the 
format and content for presentation of tables, listings, and figures (TLFs). 
Summary statistics will be provided for the observed value and change from baseline 
will be summarized. 
Unless otherwise specified, continuous data will be summarized in terms of the mean, 
standard deviation, minimum, maximum, median, and number of observations. If the 
  


I1F-IN-RHCZ

Page 20 of 60 
raw data recorded in the database has N decimal places, then the summary statistics 
would have the following decimal places:  

Minimum, maximum: N

Mean and median: N +1

Standard Deviation (SD)/ Standard Error of the Mean (SEM): N + 2

CI: N+1

Point estimate: N+1
In general, the maximum number of decimal places reported shall be 4 for any 
summary statistic. 
Categorical data will be summarized as number of patients in the analysis population, 
the number of patients providing data at the relevant time point, frequency counts (n) 
and percentages (%) corresponding to the appropriate method. Percentages will be 
presented to 1 decimal place. Percentages will not be presented for zero counts. 
For condition/event that is gender-specific (as defined by the Medical Dictionary for 
Regulatory Activities [MedDRA]), the denominator and computation of the percentage 
will include only patients from the given gender. 
In general outputs for Active PsA participants will be displayed as “Active PsA with 
PsO” to represent those mentioned in the corresponding sections as “with 3% or more 
BSA of PsO” and “Active PsA without PsO” for those that do not satisfy this criterion.

Exposure and compliance to treatment
12.1 Variables and derivations 
The date of first treatment administration will be derived as the first date of dosing from 
the exposure eCRF page. The date of last treatment administration will be derived as 
the date of last treatment administration from the exposure eCRF page.  
The following parameters will be presented to summarize the exposure to treatment: 

Number of participants received first dose

Number of participants received all doses within induction dosing period and
maintenance period

Number of participants received doses at each visit (displayed by weeks)

Duration of exposure (days)= [Date of last injection of the treatment period -
Date of first injection for the treatment period] +1

Total exposure in patient years= (Sum of duration in days of exposures for all
patients in treatment group)/ (365.25)

Total dose (in mg) is calculated by the summation of dose for each active
injection taken during the treatment period
Compliance will be assessed by the prescribed number of injections needed versus 
the number of injections administered to the participants. 
Compliance to the treatment in percentage for Ixekizumab for PsO and Ixekizumab for 
PsA participants will be calculated as follows: 
𝐶𝑜𝑚𝑝𝑙𝑖𝑎𝑛𝑐𝑒 𝑡𝑜 𝑡ℎ𝑒 𝑡𝑟𝑒𝑎𝑡𝑚𝑒𝑛𝑡  (%) = 100 ×
𝐴𝑐𝑡𝑢𝑎𝑙 𝑡𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑖𝑛𝑗𝑒𝑐𝑡𝑖𝑜𝑛 𝑎𝑑𝑚𝑖𝑛𝑖𝑠𝑡𝑒𝑟𝑒𝑑
𝑃𝑟𝑒𝑠𝑐𝑟𝑖𝑏𝑒𝑑 𝑡𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑖𝑛𝑗𝑒𝑐𝑡𝑖𝑜𝑛𝑠 𝑡𝑜 𝑏𝑒 𝑎𝑑𝑚𝑖𝑛𝑖𝑠𝑡𝑒𝑟𝑒𝑑
For the calculation of the prescribed total number of injections to be administered refer 
to the Protocol section 6.2 Table RHCZ.6.2. For participants who have discontinued 
early from study the prescribed total number of injections are only calculated up to the 
visit of discontinuation. Dosing Summary for the Induction and Maintenance Periods. 
A participant will be considered overall compliant for treatment if he/she is missing no 
more than 20% of the expected doses, does not miss 2 consecutive doses, and does 
not over-dose (i.e., take more injections at the same time point than specified in the 
protocol).

Adverse events
16.1 Variables and derivations 
Adverse Events (AEs) will be coded using MedDRA central coding dictionary, Version 
26.0 or later. 
TEAE is defined as an event that first occurred or worsened in severity after baseline 
and on or prior to the date of the last visit within the treatment period. Both the date/time 
of the event and the date/time of the injection are considered when determining 
TEAEs. TEAEs will be assigned to the treatment period in which they first occurred or 
worsened. 
The MedDRA Lowest Level Term (LLT) will be used in the treatment-emergent 
computation. The maximum severity for each LLT during the baseline period will be 
used as baseline severity (in some cases baseline period is a single time point). Events 
with a missing severity during the treatment period will be considered treatment 
emergent. The treatment period will be included as post-baseline for the analysis. If an 
event is pre-existing during the baseline period but it has missing severity, and the 
event persists during the treatment period, then it will be considered as treatment-
emergent, regardless of the post-baseline level of severity. Adverse events with a 
particular LLT will be classified as treatment-emergent if they first start on or after the 
first dose date in the treatment period (i.e., a patient has no pre-existing conditions with 
that LLT) or if the severity is greater than the pre-treatment severity for that LLT. 
A follow-up emergent adverse event (FEAE) is defined as an event that first occurred 
or worsened in severity after the date of Week 24 (Visit 6) or the ETV.  
For events that are gender specific, the denominator and computation of the 
percentage will include only participants from the given gender. 
In section 26 Appendix 2 the algorithm is given for calculation of partial date imputation 
for adverse events (AEs), and it will be used for partially missing adverse event start 
and end date imputation. 
Safety data collected after study treatment discontinuation will be summarized 
separately. 
The following parameters will be summarised for the overview of participants adverse 
events: 

Any AEs

Any TEAEs

Drug-Related TEAEs

TEAEs by maximum severity

Action taken with study treatment (Dose not changed, Drug interrupted, Drug

16.2 Analysis 
An overview summary will be presented for adverse events within treatment period 
and within study as (n=number of participants, m=number of events and 
%=percentage of participants) by Ixekizumab dosing regimen [Q2W/Q4W and 
Q4W/Q4W] and total using SAF population. 
By-participant listings of Pre-treatment AEs, TEAEs, Serious AEs and AEs resulting in 
death and AEs leading to study/treatment discontinuation will be presented, using SAF 
population. 
Note: If there are uncoded adverse events, then the uncoded category will be added 
in the AEs by SOC/PT summary tables. 
When the SOC is presented, events will be ordered by decreasing frequency in the 
overall group and then in the Q2W/Q4W group, and then in Q4W/Q4W group within 
SOC.  
For incidence counts, each patient will be counted only once within each PT and within 
each SOC. Percentages will be based on the number of patients in a particular 
treatment group.  
For events that are gender specific, the denominator and computation of the 
percentage will include only patients from the given gender. 
Additionally, incidence rate (IR) per 100 patient years will be added in the adverse 
events table. Incidence rate per 100 patient years is defined as follows: 
Incidence Rate (IR) per 100 patient years= (Total number of patients with incident 
event)/(Total time at risk)*100.  The 95% CI is calculated using below method: 
The sequence of first occurrences of an event will be assumed to follow approximately 
a Poisson distribution with constant intensity ‘λ’, where ‘λ’ is incidence rate. For 
analysis, the number of subjects with events (R) will be counted. Then, the Chi-square

Potential AESIs will be identified by a standardized MedDRA query (SMQ) or a Lilly-
defined MedDRA PT listing. Preferred terms within an SMQ will be classified as broad 
or narrow. In the Lilly-defined MedDRA PT listings, Lilly has provided the broad and 
narrow classification. The Lilly-defined broad terms are for a more sensitive search of 
potential events of interest and the Lilly-defined narrow terms are for a more specific 
search. Therefore, the summaries will include the classifications of broad term (same 
as pooling narrow and broad terms together) and narrow term.

Secondary efficacy assessments
20.1 Endpoint specific to Psoriasis (PsO) with no Active PsA and Psoriatic 
Arthritis (PsA) participants with 3% or more BSA of PsO 
 Endpoints: 

Proportion of participants with PASI 75 (defined as 75% improvement from
baseline in PASI) at Week 12

Proportion of participants with an sPGA psoriasis score of 0 or 1 (0, 1) at Week
12
20.1.1 Variables and derivations 
20.1.1.1 PASI 75 (defined as 75% improvement from baseline in PASI) at Week 
12 
1. Measure: PASI Score
2. Description: The PASI will be used to assess PsO and PsA. The PASI combines
assessments of the extent of body-surface involvement in 4 anatomical regions
(head, trunk, arms, and legs) and the severity of desquamation (scaling), erythema,
and plaque induration/ infiltration (thickness) in each region, yielding an overall
score from 0 for no psoriasis up to 72 for the most severe disease. Refer to the
protocol section 8.1.1 for more details.
3. Variable: PASI 75: A clinically meaningful response; at least a 75% improvement
in PASI score from baseline.
4. Derivation: The composite PASI score is calculated by multiplying the sum of the
individual-severity scores (Severity is rated for each index (R, S, T) on a 0-4 scale
(0 for no involvement; up to 4 for very severe involvement) for each area by the
weighted area-of-involvement score for that respective area, and then summing
the 4 resulting quantities as follows:
PASI = 0.1(Rh + Th + Sh)Ah + 0.2(Ru + Tu + Su)Au + 0.3(Rt + Tt + St)At + 0.4(Rl
+ Tl + Sl)Al
 Where, 
Rh, Ru, Rt, Rl = redness score of plaques on the head, upper limb, trunk, and lower 
limb, scored 0-4 respectively. 
Th, Tu, Tt, Tl = thickness score of plaques on the head, upper limb, trunk, and lower 
limb, scored 0-4 respectively. 
Sh, Su, St, Sl = scaliness score of plaques on the head, upper limb, trunk, and lower 
limb, scored 0-4 respectively.  
Ah, Au, At, Al = numerical value translation of % area of psoriatic involvement score 
for the head, upper limb, trunk, and lower limb, respectively

Page 40 of 60 
PASI scores are treated as a continuous score, with 0.1 increments within these 
values. If any individual score is missing, the PASI score will not be calculated, hence 
will be declared as missing. 
20.1.1.2 sPGA psoriasis score of 0 or 1 (0, 1) at Week 12 
1. Measure: sPGA psoriasis score
2. Description: The sPGA is the physician’s determination of the participant’s
psoriatic lesions, overall, at a given time point. Overall, lesions are categorized by
descriptions for induration, erythema, and scaling. For the analysis of responses,
the participant’s PsO/PsA is assessed as clear (0), minimal (1), mild (2), moderate
(3), severe (4) or very severe (5). However, for this endpoint specific our interest is
in the sPGA psoriasis score of 0 or 1 (0, 1) at Week 12.
3. Variable: sPGA psoriasis score of 0 or 1 (0, 1) at week 12.
4. Derivation: if the question in eCRF “What is the Static Physician Global
Assessment Score” is answered as 0 or 1 at corresponding week 12.

the 2 wrists, the 10 metacarpophalangeal joints, the 2 interphalangeal joints 
of the thumb, the 8 proximal interphalangeal joints, and the 2 knees. The 
following equation will be used to calculate the DAS28:  
DAS28-CRP = 0.56(√𝑇𝐽𝐶 28) + 0.28(√𝑆𝐽𝐶 28) + 0.36(ln(𝐶𝑅𝑃+ 1)) + 0.014(𝑉𝐴𝑆) +
0.96 
3. Variable: Change from baseline in DAS28-CRP
4. Derivation: Change from baseline in DAS28-CRP = Post baseline
DAS28-CRP value – Baseline DAS28-CRP value

Change from baseline in PASI [75, 90, 100]:
PASI score calculated using derivation mentioned in Section 20.1.1.1.
Change from baseline in PASI total score = Post baseline PASI total score
value – Baseline PASI total score value.

sPGA (0, 1) and sPGA (0): The sPGA is the physician’s determination of the
participant’s psoriatic lesions, overall, at a given time point. sPGA captured on
the eCRF page “Static Physician Global Assessment Scale”. Refer to the
Section 20.2.
1. Measure: sPGA
2. Description: Refer Section 20.2
3. Variable: sPGA (0, 1)], [sPGA (0)]
4. Derivation: sPGA captured on the eCRF page “Static Physician Global
Assessment Scale”. Refer to the Section 20.2.

Change from baseline in Body surface area (BSA): BSA captured on the
eCRF page “Body Surface Area”. 
Change from baseline in BSA = Post baseline BSA value – Baseline BSA 
value 

DAPSA outcome:
DAPSA=Tender Joints Count (out of 68) + Swollen Joints Count (out of 66) + 
CRP + Patient's assessment of disease activity + Patient's assessment of Pain 
DAPSA remission (defined as  ≤ 4), DAPSA low disease activity (defined as ≤ 
14) and mean change from baseline in DAPSA score by visit will be derived.
The Patient’s assessment of disease activity and Patient’s assessment of Pain
is calculated on a 10-point scale for the DAPSA score.

Appendix 1: Programming conventions for Tables, Data Listings and
Figures (TLFs)
Programs will be developed and maintained and output will be verified in accordance 
with current risk-based quality control procedures. Tables, figures, and listings will be 
produced with validated software. The production environment for statistical analysis 
consists of statistical analysis software; for example, the SAS System version 9.4 or 
later. 
The standards provided in this section are for programming reference, based on the 
actual data modifications can be done later.  
All percentages (%) for a specific summary are calculated using the total number of 
participants included in the relevant analysis population as the denominator, unless 
otherwise specified. 
Data listings will be based on all participants, unless otherwise specified. 
In general, if we have no response or record for respective parameter in data (i.e. n=0) 
then while presenting statistics in table only n will be presented as “0” and other 
statistics will be left blank. In case we have only one response or record for respective 
parameter (i.e., n=1) in data then statistic SD in table will be left blank. 
By default, for continuous measures, summary statistics will include, unless otherwise 
specified: 

n

Mean

Median

Maximum

Minimum

SD

Frequency of Missing Values.
For categorical measures, summary statistics will include, unless otherwise specified: 

Frequency of non-missing values

Percentage, and

Frequency of Missing Values.
25.1 Paper size, orientation and margins 
The margin, page size and line size specifications as stipulated in Table 23.1 will be 
used for the presentation of all TLFs.

Appendix 4: Algorithm for determining ACR responses
Details presented in this appendix will use “x” as a generic symbol, and the 
appropriate number (either 20, 50, or 70) is to be filled in when implementing in 
dataset programming code. 
ACRx response is defined as ≥x% improvement from baseline in tender joint count 
(68 counts) and ≥x% improvement in swollen joint count (66 counts), and ≥x% 
improvement in at least three of the following five items: 

Patient’s global assessment of arthritis pain

Patient’s global assessment of disease activity

Physician’s global assessment of disease activity

HAQ-DI

CRP
The following abbreviations will be used throughout this appendix to refer to the items 
needed in the algorithm definitions: 
Parameter 
Abbreviation for the 
Parameter 
% improvement in tender joint count 
TJC68 
% improvement in swollen joint count 
SJC66 
% improvement in patient’s assessment pain 
PATPAIN 
% improvement in patient’s global assessment of 
disease activity  
PATGA 
% improvement in physician’s global assessment 
of disease activity 
PHYGA 
% improvement in HAQ-DI 
HAQ 
% improvement in CRP 
CRP 
For all seven parameters mentioned above, % improvement at a visit is calculated 
as: 
(Baseline value – value at visit) * 100 / baseline value. 
To calculate the observed ACRx response at a visit: 

Step1: If the patient discontinued from the study prior to reaching the visit,
then STOP – assign ACRx response as blank (i.e., missing). Otherwise,
calculate the % improvement at the visit for all seven parameters as
described above.

Step2:
o
If TJC68 AND SJC66 are BOTH ≥x%, then proceed to step3.
o
If both are non-missing but one or both is <x%, then STOP – assign
the patient as a non-responder for ACRx.
o
If either or both are missing, proceed as follows:
  


I1F-IN-RHCZ 
Statistical Analysis Plan 
15-Nov-24
Version 3.0 
CONFIDENTIAL 
Page 60 of 60 
a. If both are missing, then STOP – assign ACRx response as blank
(i.e., missing).
b. If one of TJC68 or SJC66 is missing and the non-missing value is
<x%, then STOP – assign the patient as a non-responder for
ACRx.
c.
If one of TJC68 or SJC66 is missing and the non-missing value is
≥x%, then STOP – assign ACRx response as blank (i.e., missing).

Step3: Consider the following five variables: PTPAIN, PTDISACT,
PHYSDISACT, HAQ, and CRP.
o
If three or more items are missing, then STOP – assign ACRx
response as blank (i.e., missing).
o
If three or more items are non-missing, then proceed with the following
order:
a. If at least three items are ≥x%, then STOP – assign the patient as
a responder for ACRx.
b. If at least three items are <x%, then STOP – assign the patient as
a non-responder for ACRx.
If less than three items are ≥x%, then STOP – assign ACRx response as blank.
