Endpoints
Primary endpoint : Proportion of patients with Complete Renal Response at 
week 52
Secondary endpoints : 
Proportion of patients with Complete renal response at week 26
Proportion of patients with Partial renal response at week 26 and 52
Proportion of patients with Major renal response at week 26 and 52
Safety criteria:
Physical examination, vital signs (BP, PR), weight, 12-lead ECG, laboratory 
tests, adverse events and tolerability
Statistical methods:
The primary objective is to define a suitable dose for BI 655064 regarding 
efficacy and safety for further pivotal testing in Phase III. For this purpose, a 
multiple comparison procedure with modelling (MCPmod) approach is 
considered. The primary endpoint is Complete Renal Response after 52 weeks 
of treatment. Comparisons between treatment groups will be exploratory in 
nature and based on the numerical comparison of the respective response rates 
including confidence intervals when appropriate.

Footnotes:
1.
Visit 2.1 and 2.2 are necessary for IV steroids injections only. Refer to section 4.2.1. IV methylprednisolone 
injections to be done only to reach 1.5 g total dose if not reached within 6 weeks prior to randomisation. If a higher 
dose of IV steroid is considered necessary by the investigator a total dose of up to 3g is acceptable.
2.
Physical exam includes height (at screening only), vital signs and weight. xc is a complete physical examination, xt 
is a targeted physical examination. See section 5.3.1 for description.
3.
PK samples will be collected before study medication administration on these days if the visit date coincides with 
a day of injection; therefore study medication should be administered on site in that  case. If the visit does not 
correspond to an injection day, the PK sample will be taken at anytime during the visit. Exact date and time of 
sampling should be recorded. See Section 5.4
4.
Oral glucocorticoids have to be started on day 4 (or day 1 if IV steroids were already received) and tapered to 
10mg prednisone equivalent within 12 weeks.
5.
Starting from week 2, patients have to administer the injections with BI 655064/placebo by themselves always 7 
days after the previous dose.
6.
Safety lab tests : details of tests is given in section 5.3.3
7.
Pregnancy test will be performed in women of childbearing potential every 4 weeks. A serum pregnancy test will 
be performed at screening visit. Urine dipstick tests will be done during the screening phase (8-10 days after the 
first test) and immediately before starting medication. It will be repeated at visits every 4 weeks and will be 
provided for at home pregnancy testing as soon as visit intervals are > 4 weeks,. In case of a positive urine 
pregnancy test result, a blood sample for serum pregnancy test will be drawn for confirmation. Only those females 
with a negative pregnancy test will receive study medication and will be allowed to start treatment with MMF 
8.
Will be measured in serum and urine
9.
Questionnaires should be completed in the following order: LupusPRO, SF-36, FACIT-F, before any other visit 
assessment
10. EOT visit has to be carried-out for all patients when they stop treatment. At week 52, patients who reach at least 
partial response (based on values obtained at week 46) will be offered to enter a maintenance trial (trial 1293.13).
Patients who stopped treatment before week 52 will not be allowed to participate in the maintenance trial.
11. Follow up visits to be performed after end of treatment except for patients entering the maintenance trial 1293.13
and patients who have withdrawn drug prematurely
12. For randomized patients leaving the study before the planned EOS, their vital status should be collected at week 
60

INTRODUCTION
MEDICAL BACKGROUND
1.1
Lupus nephritis (LN) i.e. kidney involvement (mainly glomerulonephritis) is defined by 
persistent proteinuria >0.5 g/day (or a spot urine protein / creatinine ratio >0.5) and active 
urinary sediment (>5 red blood cells/high power field (RBC/HPF), >5 white blood cells 
(WBC)/HPF, or cellular casts limited to RBC or WBC casts (R12-4273). LN in SLE varies 
with ethnic background ranging from about 35% in Caucasians to about 46% in Hispanics or
Asians and to about 50% in African Americans. Survival in patients with SLE is 
approximately 92% at 10 years after diagnosis but significantly reduced to 88% after 10 years 
in the presence of lupus nephritis (R12-4273). Among the different ethnicities, African-
Americans show the worst clinical outcome and the lowest response to current therapy. In 
addition, poor socio-economic status is associated with lower outcome. Persistent active and 
long-lasting lupus nephritis causes end-stage renal disease (ESRD) and death.
Renal biopsies from SLE patients with LN show a spectrum of vascular, glomerular, and 
tubulointerstitial lesions. The glomerular injury is determined by immune-complex 
localization on mesangial, endothelial and epithelial cells. Depending on these changes lupus 
nephritis can be classified by the current ISN/RPS classification (R12-5040). In this 
classification, LN is divided into 6 classes ranging from relatively mild impairment (class I 
and II) to global sclerosis in >90% of the glomerula (class VI). Patients with LN class III-V 
show clinical signs of haematuria, symptomatic proteinuria and loss of Glomerular Filtration 
Rate (GFR). These patients are at high risk for irreversible kidney damage leading to ESRD. 
Therefore, these patients are the primary target population for immunosuppressive therapy.
Within patients suffering from LN, about 25% are class III, 40% class IV and 10% class V. 
About 1/6 of class III and IV will also have class 5 (overlap).
Although not approved for LN, cyclophosphamide (CYC) and mycophenolate mofetil 
(MMF) each in combination with glucocorticoids (GC) have been shown to improve clinical 
symptoms of active LN and to reduce the risk of progression to ESRD (e.g. R12-4322, R12-
4326, R12-4285, R12-4284, P12-11005). However, the complete response rates remain low 
and there is a relevant risk of relapse. Furthermore, both treatments for LN may be associated 
with significant toxicity (for example, infertility, infection, malignancy). As a consequence, 
there is a high unmet medical need for treatments in LN.
The generation of the auto antibodies is dependent on T cell-B cell interactions within the 
lymph node and requires CD40-CD40L (CD40 Ligand) to drive B cell proliferation and 
formation of germinal centres. Based on current knowledge (refer to section 2.3) there is a 
stronger evidence for a critical role of the CD40-CD40L in LN class III and class IV than LN 
class V (R12-3090). Therefore, the clinical development for BI 655064 will focus on LN 
patients with class III and IV including overlap with class V.

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
RATIONALE FOR PERFORMING THE TRIAL
2.1
Patients with LN class III-V are at high risk for irreversible kidney damage leading to ESRD, 
dialysis and death. Although being not approved for therapy of LN, CYC or MMF, each in 
combination with glucocorticoids have been shown to improve clinical symptoms of active 
LN and to reduce the risk of progression to ESRD. Therefore, the combination of one of 
these two agents with glucocorticoids is considered as current standard of care for LN.
However, only about 20-30% of patients treated with MMF or CYC show a complete renal 
response and another about 20% show at least a partial response. There is a high risk of 
relapse justifying long-term maintenance therapy. Both treatments for LN may be associated 
with significant toxicity (for example, amenorrhoea, infertility, infection, malignancy).
Thus, there is high unmet need for improvement in clinical efficacy and treatment 
alternatives for LN should be explored. Blocking the CD40-CD40L pathways will impact 
multiple mechanisms which are involved in pathology of LN by inhibiting B-cell and T-cell 
responses as well as directly influence the inflammation in the kidney by decreasing CD40L 
induced MCP1 secretion of endothelial cells as well as CD40L induced IL-6 secretion by 
proximal tubular epithelial cells. Therefore, targeting the CD40-CD40L pathway is 
considered a potential effective approach for the treatment of this disease.
The primary objective of this study is to investigate efficacy of BI 655064 as add-on therapy 
to Standard of Care (SOC) in patients with active lupus nephritis in order to establish proof 
of concept, and characterize the dose-response relationship within the therapeutic range, and 
select the target dose for phase III development. To achieve this, the statistical design is 
based on the multiple comparison and modelling (MCPmod) approach for dose finding that 
combines multiple comparison procedures and modelling techniques.
Rationale for SOC selection
There is no approved treatment for LN but the ACR (R12-4273) and the EULAR/ERA-
EDTA guidelines (R12-4921) recommend the use of MMF or CYC in combination with 
glucocorticoids, starting with three consecutive pulses of intravenous (i.v.)
methylprednisolone, and followed by oral glucocorticoids. The efficacy of MMF- and CYC-
based induction therapy in LN is quite comparable (R15-3723 and R15-5330). For this trial, 
MMF-based SOC in combination with glucocorticoids with initial i.v. methylprednisolone 
pulse was selected based on feedback from international experts who in the majority

presently recommend MMF. MMF and i.v. methylprednisolone are non investigational 
products in this trial.
TRIAL OBJECTIVES
2.2
The overall purpose of this trial is to assess the efficacy of three different doses of BI 655064 
against placebo as add-on therapy to standard of care (SOC) treatment for active lupus 
nephritis (See section 4.2.1) in order to characterize the dose-response relationship within the 
therapeutic range, and select the target dose for phase III development.
Other objectives of this study are safety, tolerability, pharmacokinetics, and 
pharmacodynamics of BI 655064.
Study endpoints are listed in Section 5.

Patients with LN class III-V are at considerable risk for irreversible kidney damage leading 
to ESRD, dialysis and death. CYC or MMF, each in combination with glucocorticoids are 
looked upon as current standard of care for LN.
However, only about 20-30% of patients treated with induction treatment either combining 
MMF or CYC with steroids show a complete renal response and another about 20% show at 
least a partial response within a year. Both treatments for LN may be associated with 
significant toxicity (for example, amenorrhoea, infertility, infection, malignancy). Taken 
together, there is a high unmet need for a better therapy.
Anti-CD40 therapy offers clear differentiation compared to current therapies with respect to 
mechanism by targeting humoral responses and inflammatory responses amplified locally in 
the kidney (in LN). Although clinical proof of concept remains to be established directly 
with anti-CD40, effective blockade of CD40-CD40L pathway using CD40L antibodies has 
been shown in many pre-clinical LN studies. Preclinical studies demonstrated direct effects 
of CD40L on immune (B cells, monocytes ) and non-immune resident kidney cells  
(proximal tubular epithelial cells, mesangial cells)  which secrete inflammatory cytokines 
that are inhibited by BI 655064. A small subset independent analysis of LN patients treated 
with anti-CD40L ab, ruplizumab by two investigators (R12-4866 and R15-4206) showed a 
decrease in auto-antibody titers, decreased proteinuria and decrease in disease scores thus 
underscoring the importance of CD40 pathway inhibition. Therefore, targeting CD40 
pathway with BI 655064 shows high promise as an effective for treatment of LN.

Treatment with MMF is associated with higher risk of infections, blood and lymphatic 
system, gastrointestinal side effects, and teratogenicity. For further details please refer to the 
current prescribing information
Treatment with i.v. glucocorticoids is associated with higher risk of side effects. For further 
details please refer to the current prescribing information
It is important to note that all patients in this study will receive standard of care treatment for 
lupus nephritis. The majority of patients (2/3) will be randomized to add-on treatment of BI 
655064 to SOC and even the lower dose of BI 655064 is expected to show some additional 
clinical benefit based on modelling of PK and PD. Patients in the placebo group will receive 
placebo to BI 655064 as add-on to standard of care treatment for lupus nephritis. 
In conclusion, the sponsor believes that the activity demonstrated in patients with RA and 
positive trends in biomarker data from patients with RA and ITP, coupled with an acceptable 
safety profile generated to date, support initiation of a trial in patients with lupus nephritis 
and that the potential clinical benefit could surpass the potential risks.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This study will be randomized, parallel-design, dose-ranging, placebo-controlled, double-
blind, multi-centre and multi-national. A total of up to approx. 120 male and female patients 
with active lupus nephritis will be randomized in this trial in about 22 countries. There will 
be three parallel BI 655064 dose groups (approx. 20, 20 and 40 patients) and one placebo 
dose group (approx. 40 patients). The patients will be randomized 1:1:2:2 to these dose 
groups. Randomisation will be done with stratification by ethnicity (Asians vs Non- Asian) 
and proteinuria at screening <3g/day or ≥3g/day (respectively UP/UC<3 or UP/UC≥3. All 
patients will receive standard of care (SOC) treatment for lupus nephritis, consisting of a 6 
month initial phase with 2-3 g MMF/day starting with high dose steroids which will be 
tapered down to 10 mg prednisone equivalent within 12 weeks after randomization (Refer to 
section 4.2.1), followed by a second phase (from week 26 on) with 1-2 g MMF/day in 
combination with steroids <=10 mg prednisone equivalent/day. BI 655064 will be 
administered subcutaneously at 3 different doses. For the first 3 weeks the patients will 
receive two parallel injections/week on the same day of BI 655064 and/or placebo. Then the 
patients will receive one injection/week of BI 655064 or placebo for up to 52 weeks (12 
months). Patients in the placebo dose group will receive only injections of placebo to BI 
655064. 
The primary endpoint (complete renal response as defined in section 5.2) will be assessed at 
52 weeks. Patients with at least a partial response at week 52 will be offered to enter a 
maintenance trial (1293.13).

3.1.1
Administrative structure of the trial
The trial will include the review of safety data by an internal, independent DMC with the 
support of an independent statistician. The purpose of the DMC is to ensure the welfare of 
subjects participating in the trial is maintained by monitoring the trial for possible, untoward 
harmful effects or inappropriate frequency of adverse events. 
The DMC will evaluate and analyse accrued, unblinded data in order to recommend whether 
the trials should continue, be modified or stopped due to safety or ethical concerns.
Further details are specified in the Data monitoring Committee operating Charter. The DMC 
charter will be available before the start of patient recruitment.
Boehringer Ingelheim has appointed a Trial Clinical Monitor, responsible for coordinating all 
required activities, in order to:
-
manage the trial in accordance with applicable regulations and internal SOPs,
-
direct the clinical trial team in the preparation, conduct, and reporting of the trial,
-
order the materials as needed for the trial, 
-
ensure appropriate training and information of local clinical monitors (CML), Clinical 
Research Associates (CRAs), and Investigators of participating countries.
Data Management and Statistical Evaluation will be done by BI according to BI SOPs.
Tasks and functions assigned in order to organize, manage, and evaluate the trial will be 
defined according to BI SOPs. A list of responsible persons and relevant local information
can be found in the ISF.
A Coordinating Investigator will be nominated and will be responsible to coordinate 
Investigators at different centers participating in this multicentre trial. Tasks and 
responsibilities will be defined in a contract. Relevant documentation on the participating 
(Principal) Investigators and other important participants, including their curricula vitae, will 
be filed in BIRDS.
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
3.2
CONTROL GROUP(S)
Study 1293.10 is a double-blind, randomized, parallel-design, dose-ranging, placebo-
controlled clinical trial.
The trial design has been chosen to allow proof-of concept and selecting appropriate dose 
regimens for subsequent Phase III trials. The treatment duration of 52 weeks was selected, 
based on literature (e.g. R15-4294; R15-3157 ) and feedback from external experts, some 
patients improve further between 6 and 12 months and the 12 month time point may provide 
a better differentiation vs. the control group (R15-3718).
The study is aimed to evaluate the effects of the drug on renal activity. Study outcomes will 
focus on renal function endpoints. The primary endpoint is complete renal response at 52 
weeks (12 months) as defined in section 5.2. Secondary endpoints assessing the response 
level at 26 and 52 weeks will complete the picture. Treatment of placebo as add-on to SOC

has been selected as control group as a placebo treatment add-on to SOC is recommended by 
Health Authorities (HA) as comparisons for dose finding in phase II trials. In addition there 
is no approved active comparator. MMF-based SOC was selected based on feedback from 
international experts who in the majority presently recommend MMF. For reasonable 
comparison and analysis, harmonization of steroid treatment is needed and a tapering 
schedule is provided which is followed by all patients. ACR and EULAR/ERA-EDTA 
guidelines recommend to taper steroids down to lowest effective dose. The 10 mg prednisone 
equivalent target was selected based on external expert recommendation. This amount is 
looked upon as balance between side effects induced by long-term steroid-treatment and 
efficacy. The 12 week time point to reach the 10 mg is selected as immunosuppressive 
therapy is expected to have reached full effect at that time. BI 655064 is expected to be at 
steady state for some weeks at that time too..  Ideally, patients entering the trial would not 
have started an induction therapy before randomization; however, it is anticipated that some 
patients who might have already started a short term induction therapy with SOC might 
benefit from the combination treatment with BI 655064. According to feedback from 
external experts, it’s not expected that short term induction treatment before randomization 
will have a major impact on the outcome of a 1 year endpoint. An analysis on the effect of 
prior treatment with abatacept showed that patients who are naïve to induction treatment had 
the best response, whereas those who had received >3 months induction showed the poorest 
response (R15-3717).
In this trial (1293.10) start of induction treatment prior to randomization is limited to 6 weeks 
as this will allow for some prior treatment with MMF while maintaining a level of 
homogeneity to better assess treatment effect in this Phase 2 study. High dose steroids have 
significant impact on the short term response and have potentially relevant side effects. To 
keep the population included in the trial more homogenous and to avoid increased risk of 
side-effects, the total amount of i.v. steroids has to be limited. A total amount of 1.5 g of i.v. 
steroids is recommended by ACR (R12-4273) and EULAR/ERA-EDTA (R12-4921) for
induction therapy (3x500 mg i.v.). For severe cases a maximal total amount of 3 g of iv 
steroids may be considered (3x1000 mg i.v.).
Thus, patients who had started induction with high i.v. dose steroids but < 3g total i.v. within 
6 weeks prior to randomisation (D1) will be eligible for the trial. Dose finding and proof of 
clinical concept are combined within this single trial. In order to achieve both aims in an 
efficient fashion, i.e. with a comparably large success probability, the generalized MCPmod 
approach (R10-1424) has been implemented as the statistical design. This approach is able to 
incorporate potential relationships between the different doses into the evaluations via 
optimal test contrasts which increases the probability of success compared to classical 
multiple comparison procedures. MCPMod has been evaluated by the EMA recently and is 
considered to be an efficient statistical methodology for model-based design and analysis of 
Phase II dose finding studies under model uncertainty (EMA qualification opinion). As a 
second step for designing the trial efficiently the allocation ratio has been chosen to be 
2:1:1:2 for placebo, 120mg, 180mg, and 240mg respectively. Thereby the success probability 
of the trial is increased further compared to a balanced allocation ratio whilst keeping the risk 
of a false positive outcome at the same level. A sufficiently broad set of candidate shapes for

SELECTION OF TRIAL POPULATION
3.3
A sufficient number of patients with active lupus nephritis will be screened to ensure that an 
adequate number of patients will be randomized. It is planned that 120 male and female 
patients who meet the eligibility criteria will be randomized in the study. The planned 
number of randomized patients per site is 1 – 2 (approx. 80 to 100 sites). Enrolment will be 
competitive and will be closed when the total number of randomized patients has been 
reached, regardless of total enrolment at individual centres.
A log of all patients enrolled into the trial (i.e. who have signed informed consent) will be 
maintained in the ISF at the investigational site irrespective of whether they have been 
treated with investigational drug or not.

In case a patient withdraws drug prematurely, it is important that his/her renal function 
parameters and safety data are recorded until the end of the 52 weeks period. Thus, all 
patients will be asked to follow some visits until 52 weeks. The patient will undergo the 
procedures for early treatment discontinuation and continue visits as described in section 
6.2.3 until week 52.
For all patients the reason for withdrawal (e.g. adverse events) must be recorded in the 
(e)CRF. These data will be included in the trial database and reported.
Discontinuation of the trial by the sponsor
3.3.4.2
Boehringer Ingelheim reserves the right to discontinue the trial overall or at a particular trial 
site at any time for the following reasons:
1. Failure to meet expected enrolment goals overall or at a particular trial site
2. Emergence of any new toxicological findings /efficacy/safety information invalidating 
the earlier positive benefit-risk-assessment that could significantly affect the 
continuation of the trial
3. Violation of GCP, the CTP, or the contract disturbing the appropriate conduct of the 
trial
4. Other significant safety concerns across all patients 
5. The sponsor decides to discontinue the further development of BI 655064.
The Investigator / the trial site will be reimbursed for reasonable expenses incurred in case of

medication will be labelled with the trial code and a unique medication identification 
number. At each applicable visit, the IRT will assign each patient medication numbers for 
each weekly drug administration. To facilitate the use of the IRT, the Investigator will 
receive all necessary instructions and the site-user manual available in the ISF.
4.1.3
Selection of doses in the trial
The doses of BI 655064 and weekly administration were selected based on the results of 
(Refer to the 
Investigator’s Brochure (U11-1925) for further information.).
4.1.4
Drug assignment and administration of doses for each patient
IRT will be used to allocate medication to patients throughout the study. At visits where
study medication is to be prescribed, study sites will be required to complete the medication
(re)supply module in the IRT. (Detailed information is provided in the Flow Chart). From 
week 2 on, there will be injections dispensation of syringes for home administration on the 
following week(s). It will be necessary for the investigator to instruct the patient on the 
proper administration technique for injections at home. If needed, injections could also be 
done by qualified persons e.g. a nurse.
BI 655064/placebo will be provided in sterile, preservative-free, non-pyrogenic, single-use 
pre-filled glass syringes. Prefilled syringe will be administered by subcutaneous injection. 
Any unused product or waste material will be disposed of in accordance with local 
requirements. The first dose of trial medication will be administered at the trial site for all 
patients by the investigator (or a suitably qualified designee). The patient will be required to 
stay at the study site for observation for about 1 hour following the first dosing and 30 min 
after dose 2 and 3 (or more if locally required). After proper training on subcutaneous 
injection technique and if the investigator determines that it is appropriate with medical 
follow-up as necessary, patients will self-inject the weekly study medication at home 
(between two visits) on the same day (+/- 1 day) of each week. Further information regarding 
the self-injection technique and the instructions for use will be available in the ISF for 
providing to the patients. In case of missed dose, the patient should call his investigator to 
decide about further dosing as soon as possible.
All dose-regiments will start with a loading dose to reach the target mean exposure of each
dose within 3 weeks: for the first 3 weeks (week 0, 1 and 2) the patients will receive two 
parallel injections per week (on the same day). From week 3 to end of treatment the patients 
will receive one injection per week.
Schedule of drug dispensations:
Visits 2 and 3 (week 0 and 1): syringes for the visit injection will be received
Visits 4-5-6 (from week 2): syringes for the visit injection plus next week (home) injection

4.1.5
Blinding and procedures for unblinding
Blinding
4.1.5.1
This study has a double-blind design. From the time of randomisation at Day 1 the subjects, 
investigators and sponsor staff will not be aware of the treatment allocation until database 
lock.
After all patient have completed 26 weeks treatments a BI internal interim analysis will be 
performed for the purpose of facilitating further substance development and project planning. 
This analysis will be performed by a BI internal team independent of the trial team in order 
to prevent potential introduction of operational bias. An interim analysis trial statistical plan 
prepared and approved in accordance with sponsor’s specific procedures will detail 
procedures used to ensure that some members of the trial team remain blinded. The plan will 
also contain a detailed list of functions that need to be unblinded for performing this analysis.
In order to ensure appropriate blinding, an IRT will be used for the assignment of patients to 
treatment groups and the randomization sequence will be generated using validated software 
and verified by an independent BI statistician who is not involved in the planning or 
performance of the trial. The randomization code will be kept secret by Clinical Trial 
Support up to database lock.
The randomization codes will be provided to bioanalytics prior to last patient out to allow for 
the exclusion from the analyses of pharmacokinetic (PK) samples taken from placebo 
patients. Bioanalytics will not disclose the randomization code or the results of their 
measurements until the trial is officially unblinded.
Unblinding and breaking the code
4.1.5.2
In this blinded trial, an emergency code break will be available to the Investigator / the sub-
Investigators via the IRT system. This code break may only be accessed in emergency 
situations when the identity of the trial drug must be known to the Investigator /the sub-
Investigators in order to provide appropriate medical treatment or if required to assure the 
safety of trial participants. Each site receives a manual from the IRT provider that contains 
instructions on how to unblind the treatment of a patient via the IRT (via 24-hour Emergency 
helpline). If the code break for a patient is accessed, the Sponsor must be informed 
immediately. The reason for accessing the code break, together with the date, must be 
documented on the appropriate eCRF page. In case third party needs to break the code, 
however, when the Investigator cannot be reached, the code can be opened by calling 
emergency code manager.

4.2
TREATMENT
4.2.1
Rescue medication, emergency procedures, and additional treatment(s)
There are no special emergency procedures to be followed.
Background medication:
All patients will receive standard of care (SOC) treatment for lupus nephritis based on MMF:
SOC Initial phase (week 1 – 26):

MMF: patients who are already on MMF of 2 g/day or a maximum of 3 g/day should stay 
at same MMF dose, provided that they have tolerated it well. Patients who start treatment 
with MMF or patients with a dose <2g/day should be increased to a stable MMF dose of 
2g/day. It is recommended not to increase MMF above 2g/day to reduce the risk of severe 
side-effects of MMF. In case of side effects related to MMF, a MMF dose < 2g/day is 
allowed.

AND glucocorticosteroids (GC) (methylprednisolone, recommended 500mg pulse IV for
3 days) followed by oral glucocorticosteroids, tapering to 10mg prednisone
equivalent/day within 12 weeks. Tapering of steroids should follow the tapering schedule 
in Appendix 10.1. Patients who have had already a course of IV steroids (up to a total 
dose of maximum 3g if it had been considered necessary by the investigator) within 6 
weeks prior to randomization should not necessarily repeat it depending on what they 
received. They should only have necessary pulses to reach a total of 1.5g IV steroids. E.g 
: if they have already received 2 pulses of 500mg, they will just receive one additional 
pulse. If they have already had 3 *500 mg, they simply do not repeat any IV pulse. If 
considered necessary by the investigator, a maximal dose of 1000 mg methylprednisolone
per day for up to 3 days (maximal 3000mg) is acceptable.  
SOC week 26 – 52:


Mycophenolate mofetil (MMF) 1 to 2 g/day stable + low-dose (<= 10 mg/day) 
prednisone-equivalent 
From week 26 only, in case of side effects: MMF may be reduced to 1g/day or in case of non 
tolerability, patients could be switched to Azathioprine (AZA) 2mg/kg/day + (<= 10 mg/day) 
prednisone-equivalent low-dose daily.
In patients who experience a worsening or a flare, the investigator is allowed to increase the 
steroid dose for the patient. These patients are allowed to continue treatment with BI 655064 
until week 52..
During the participation in the trial, SOC medication has to be prescribed by the investigator. 
Boehringer-Ingelheim will reimburse costs for SOC for this period according to local 
regulations, or will provide the drugs according to local regulations.
Adjunctive treatments:
All patients should stay on their respective treatment if started before screening such as:

Hydroxychloroquine (HCQ) 200 – 400 mg/day or other anti-malarial

Angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker 
(ARB) 

Statins. 
It is recommended that patients remain on stable dose for these treatments during the 
duration of the study.
There are no special emergency procedures to be followed.
Management of Adverse Events:
- In case a patient develops a serious infection during the treatment in the study, treatment 
with BI 655064 and MMF (respectively azathioprine) will be interrupted. Treatment with BI 
655064 and MMF will be restarted when the patient has recovered according to investigator’s 
assessment. In addition, patients who develop recurrent infections should have their serum 
IgM and IgG measured according to investigator’s assessment.
- In case a patient develops a thrombosis suspected to be related to immunosuppression 
during the treatment in the study, treatment with BI 655064 and MMF (respectively 
azathioprine) will be interrupted and antithrombotic therapy has to be started. Treatment with 
BI 655064 and/or MMF(respectively azathioprine) may be restarted when the patient has 
recovered according to investigator’s assessment.

- In case of suspected hepatic injury (refer to section 5.3.5.1 for definition of hepatic injury) 
during the treatment in the study, treatment with BI 655064 has to be stopped. In case the 
follow–up identifies a confounder (e.g. high dose of paracetamol) and the liver function has 
recovered, treatment with BI 655064 may be restarted according to the investigator’s 
assessment after discussion with the sponsor.
- In case of emergency surgery during treatment in the study, treatment with BI 655064 and 
MMF (respectively azathioprine) will be interrupted. Treatment with BI 655064 and MMF 
(respectively azathioprine) will be restarted when the patient has recovered according to
investigator’s assessment.
- In case of severe injection reactions, anaphylactic reactions or cytokine release syndrome, 
treatment with BI 655064 and MMF (respectively azathioprine) has to be stopped and must 
not be introduced again.
- In case of occurrence of lymphoproliferative diseases, treatment with BI 655064 and MMF 
(respectively azathioprine) has to be stopped and must not be introduced again.
- In case of side effects known to be related to higher doses of MMF (respectively

Restrictions on diet and life style
4.2.2.2
Patients should not donate blood during MMF therapy and for at least 6 weeks following 
discontinuation of MMF.
Men should not donate semen during MMF therapy and for at least 90 days following 
discontinuation of MMF
During the trial, all patients should avoid intensive physical activity and unprotected
exposure to direct sunlight. The use of tanning booths is forbidden. Intensive physical 
activity is considered activity that is of a higher intensity than usually performed by the 
individual. Fasting is not required for this study.
TREATMENT COMPLIANCE
4.3
It is recommended that patients take all doses of study medication and SOC background 
therapy according to the trial protocol unless medically indicated. Any temporary 
interruption should be discussed with the Sponsor and all patients should be advised of the 
importance in adhering to the dosing schedule.
From Visit 4 onwards, a compliance check of the trial medication will be performed at each 
clinic visit to ensure the weekly injection is being administered correctly at both the trial site 
and by the patient at home. A MMF dosing will be performed at weeks 12, 26 and 52 to 
assess compliance to background medication a posteriori. The last two intakes dates and time 
of MMF taken before the blood sampling will be recorded in RDC, based on patient’s 
interview.
Each patient will be provided with a medication bag to store unused and empty cartons of 
trial medication and a sharp bin to store all used syringes. Patients are requested to bring all 
unused trial medication and empty cartons with them to their next scheduled visit for 
compliance check. Any discrepancies should be documented and explained in the eCRF by 
the investigator or the designee. In addition, patients will be provided with a diary to record 
the intake of trial medication 
At the EOT visit as a minimum, patients are requested to return the sharp bin to the trial site 
for disposal in accordance with local requirements.

ASSESSMENT OF EFFICACY
5.2
Assessment of Renal Response:
For primary and secondary efficacy endpoints at baseline (week 0), week 26 and 52, 24h 
collection of urine will be performed in duplicates (2 times 24 h collection).
A detailed description for urine collection will be provided in the laboratory manual and 
instructions provided to the patients. At other time points, proteinuria will be assessed by 
spot urine.
Complete and partial renal responses are defined as follows:

Complete renal response (CRR) is defined as Uprot <0.5 g/day and eGFR within normal 
range; or decrease <20% from baseline if below normal range. Non responder patients 
withdrawn at 6 months are considered non responders for the 26 and 52 week timepoint
for the primary endpoint.

Partial renal response (PRR) is defined as 50% reduction of proteinuria from baseline and 
eGFR within normal range or decrease< 20% from baseline if below normal range.

Major renal response (MRR) is defined as :

if baseline proteinuria<3 g/day : CRR at week 52

if baseline proteinuria >= 3 g/day : proteinuria <1g/day at week 52.
Renal biopsies:

Renal biopsies slides or electronic files used for the diagnosis as described in inclusion 
criterion have to be available as biopsies are planned to be re-assessed centrally by one 
pathologist for retrospective analysis. An additional renal biopsy at the end of treatment is 
voluntary. The renal biopsy at the end of treatment may provide additional information on 
remaining activity or chronicity of the renal damage despite clinically low disease activity 
(R15-3725). Change in renal biopsy at week 52 compared to screening biopsy (only for 
patients with a biopsy at the end of treatment (See section 5.2)) will be evaluated.
ASSESSMENT OF SAFETY
5.3
5.3.1
Physical examination
Physical examinations will be performed as described in the Flow Chart.
Complete physical examination will include weight, vital sign assessment and general 
appearance as well as evaluation of all organ systems (eyes, ears, nose, mouth, and throat, 
neck, respiratory, cardiovascular, chest, gastrointestinal, lymphatic, musculoskeletal, skin, 
neurologic and psychiatric).
Targeted physical examination will include weight, vital sign assessment and evaluation of 
organ systems associated with AE(s) symptoms or laboratory abnormalities.
Height will be measured at screening visit only.
All abnormal findings from screeningwill be recorded on the Medical History/Concomitant 
Diagnosis e-CRF page. New abnormal findings or worsening of baseline conditions detected 
at the subsequent physical examinations will be recorded as adverse events on the 
appropriate e-CRF page.
5.3.2
Vital Signs
Systolic and diastolic blood pressure and pulse rate will be measured with the patient seated
after having rested for at least 5 minutes. All abnormal findings at screening visit will be 
recorded on the Medical History/Concomitant Diagnosis e-CRF page. New abnormal 
findings or worsening of baseline conditions detected at the subsequent physical 
examinations will be recorded as adverse events on the appropriate e-CRF page
5.3.3
Safety laboratory parameters
The laboratory tests will be performed at a designated central laboratory, and if necessary by 
additional specialist laboratories. Instructions for sample collection, processing and shipping 
are provided in the Laboratory Manual in the ISF.
The safety laboratory tests will include:

5.3.4
Electrocardiogram
Regular 12-lead Electrocardiograms (ECGs) are conducted during the trial at the visits 
indicated in the Flow chart. Rate, rhythm and repolarization changes have to be looked at, 
compared to previous one, and assessed for clinical relevance. Clinically relevant findings 
must be entered as adverse events and if necessary additional ECGs for control may be 
performed. Automatically generated interval data (PR, QRS, QT interval) and heart rate on 
the printed ECG will be collected on the eCRF. QTcB and QTcF will be calculated with HR 
and QT interval. Signed and dated printouts of either ECG tracings or electronic ECG reports 
will be kept in the patient’s medical file.
5.3.5
Assessment of adverse events
Definitions of AEs 
5.3.5.1
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product and which does not necessarily 
have to have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
Serious adverse event
A serious adverse event (SAE) is defined as any AE which:

results in death,

is life-threatening,

requires inpatient hospitalisation or prolongation of existing hospitalisation,


results in persistent or significant disability or incapacity,

is a congenital anomaly/birth defect,
or

is to be deemed serious for any other reason if it is an important medical event when 
based upon appropriate medical judgment which may jeopardize the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in the 
above definitions.
Life-threatening in this context refers to an event in which the patient was at risk of death at 
the time of the event; it does not refer to an event that hypothetically might have caused 
death if more severe.
For Japan: The following events will be handled as “deemed serious for any other reason”. 
An AE which possibly leads to disability will be reported as an SAE.
Every new occurrence of cancer will be reported as a SAE regardless of the duration between 
discontinuation of the drug and the occurrence of the cancer.
AEs considered “Always Serious”
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of AEs, which by their nature, can always be 
considered to be “serious” even though they may not have met the criteria of an SAE as 
given above.
The latest list of “Always Serious AEs” can be found in the RDC system. These events 
should always be reported as SAEs.
Adverse events of special interest (AESIs)
The term AESI relates to any specific AE that has been identified at the project level as being 
of particular concern for prospective safety monitoring and safety assessment within this 
trial, e.g. the potential for AEs based on knowledge from other compounds in the same class. 
AESI need to be reported to the Sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAE, see Section 5.3.6.
The following are considered as AESIs:
Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory parameters: 

an elevation of AST and/or ALT >3 fold ULN combined with an elevation of total 
bilirubin >2 fold ULN measured in the same blood draw sample, and/or

Marked peak aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN
These lab findings constitute a hepatic injury alert and the patients showing these lab 
abnormalities need to be followed up according to the “DILI checklist” via the RDC-system.

01-MCS-40-106-RD-03 (11.0) / Saved on: 24 Jul 2014
In case of clinical symptoms of hepatic injury (icterus, unexplained encephalopathy, 
unexplained coagulopathy, right upper quadrant abdominal pain, etc.) without lab results 
(ALT, AST, total bilirubin) available, the investigator should make sure these parameters are 
analysed, if necessary in an unscheduled blood test. Should the results meet the criteria of 
hepatic injury alert, the procedures described in the DILI checklist should be followed.
Injection reactions including anaphylactic reaction
Any suspicion of severe injection reaction and of any potential cases of anaphylaxis should 
be defined and assessed using the criteria discussed in the statement paper from Sampson HA 
(R11-4890)
Cytokine release syndrome
A cytokine release syndrome manifests when a large number of immune cells becomes 
activated and releases inflammatory cytokines. It is consistently associated with elevated 
TNFα, IFNγ, and IL-6 levels. The cytokine-release syndrome is clinically characterized by 
fever, chills, rigor and rash. Other symptoms are nausea, dyspnoea, tachycardia and 
hypotension. Potentially life-threatening complications of a cytokine release syndrome 
include cardiac dysfunction, respiratory distress syndrome, neurologic toxicity, renal and/or 
hepatic failure, and disseminated intravascular coagulation. In case of suspicion of a cytokine 
release syndrome, it is recommended to measure IL-6 levels in the local laboratory if the 
assay is available.
In general therapy with BI 655064 is immunosuppressive and potentially could increase the 
risk for infections or lymphoproliferative diseases.
Opportunistic infections and/or severe infections
Opportunistic infections include pneumocystis pneumonia, toxoplasmosa gondii encephalitis, 
cryptosporidiosis; microsporidiosis, mycobacterium tuberculosis, mycobacterium avium; 
bacterial respiratory disease, bacterial enteric infection, mucocutaneous candidiasis, invasive 
mycoses, CMV, EBV, herpes simplex, varicella zoster, human herpesvirus 8, JC virus 
infection. 
Any severe infection should also be reported as AESI.
Whenever a patient comes to a visit and reports of an (S)AE related to infections which 
occurred in the interval since the last visit, then he/she is routinely asked whether they have 
been seen/treated by a physician and whether blood samples had been taken in that context. 
Should this be answered in the affirmative then efforts should be undertaken to collect the 
respective information.
Lymphoproliferative disorders (e.g. B- and T-cell lymphoma, Non-Hodgkin 
lymphoma and Hodgkin lymphoma, hepatosplenic T-cell lymphoma)

In case of adenopathy, hepato- or splenomegaly, fever of unclear origin, night sweats or loss 
of weight, occurrence of lymphoproliferative diseases should be evaluated. As the occurrence 
of lymphoproliferative disorders is associated with active EBV-infection, patients suffering 
from active EBV infection should be carefully evaluated for the occurrence of 
lymphoproliferative diseases.
Thrombosis and adjunct immunosuppression
Immunosuppression may favour a prothrombotic state. Therefore, patients should be 
carefully followed for early signs of peripheral or central thrombosis or thromboembolic 
events.
For countermeasures and management of the above mentioned Adverse Events please refer 
to section 4.2.1 of the protocol.
The specific therapy of the listed AESIs will be according to institutional standards.
Intensity of AEs
The intensity of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Enough discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities”
The intensity of adverse events should be classified and recorded in the (e)CRF according to
the Rheumatology Common Terminology Criteria for Adverse Events (RCTCAE) 
version 2.0 developed by OMERACT (R13-3515). Refer to paper version filed in the ISF for
RCTCAE intensity/severity classification.
Causal relationship of AEs
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Yes:
There is a reasonable causal relationship between the investigational product 
administered and the AE.
No:
There is no reasonable causal relationship between the investigational product 
administered and the AE.
The causal relationship must be provided by the Investigator for all potential trial drugs, i.e. 
the BI trial drug and for all other trial drugs (such as any active comparator or placebo).

5.3.6
Adverse event collection and reporting
AE Collection
The following must be collected and documented on the appropriate eCRF by the 
Investigator:
-
From signing the informed consent onwards through the Residual Effect period 
(REP), until trial completion, all AEs (serious and non-serious), and all AESIs.
Figure 5.3.6:1 AE collection
The REP is defined as 50 days after the last trial medication application. All AEs which 
occurred through the treatment phase and throughout the REP will be considered as on 
treatment please see section 7.3.4. Events which occurred after the REP will be considered as 
post treatment events.
After the last per protocol contact the Investigator does not need to actively monitor patients 
for AEs. However, if the Investigator becomes aware of SAEs or AESIs that occurred after 
the last per protocol contact, the SAEs and AESIs should be reported by the Investigator to 
the Sponsor if considered relevant by the Investigator.
AE reporting to sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours ) to the 
Sponsor’s unique entry point (country specific contact details will be provided in the ISF). In 
specific occasions the Investigator could inform the Sponsor upfront via telephone. This does 
not replace the requirement to complete and fax the BI SAE form.
For Japan: All SAEs and AESIs must be reported immediately to the head of the trial site.
With receipt of any further information to these events, a follow-up SAE form has to be

provided. For follow-up information the same rules and timeline apply as for initial 
information.
Information required
For each AE, the Investigator should provide the information requested on the appropriate 
(e)CRF pages and the BI SAE form, e.g. onset, end date, intensity, treatment required, 
outcome, seriousness, and action taken with the investigational drug(s). The Investigator 
should determine the causal relationship to the trial medication, and any possible interactions 
between the investigational drug and a Non-Investigational Medicinal Product.
The following should also be recorded as an (S)AE in the (e)CRF and SAE form (if 
applicable):

Worsening of the underlying disease or of other pre-existing conditions

Changes in vital signs, ECG, physical examination and laboratory test results, if they are 
judged clinically relevant by the Investigator.
If such abnormalities already pre-exist prior trial inclusion they will be considered as 
baseline conditions.
All (S)AEs, including those persisting after trial completion must be followed up until they 
have resolved, have been sufficiently characterized, or no further information can be 
obtained.
SAEs which occurred during the screening period are to be reported according to standard 
procedures.
Pregnancy
Due to the teratogenic potential of MMF/AZA, highly effective contraception has to be 
performed. The reliable contraception should be used in female patient before starting MMF 
therapy and the study drug, during the treatment and until 50 days after stopping MMF and 
the study drug (and until 90 days after stopping AZA in case of AZA is used). 
A list of contraception methods meeting these criteria is provided in the patient information.
Sexually active men must be ready to use condoms$ during treatment with MMF/AZA and 
for at least 90 days after cessation of MMF/AZA treatment.
In the rare case that a female subject participating in this clinical trial becomes pregnant after 
having taken trial medication, the Investigator must report immediately (within 24 hours) the 
drug exposure during pregnancy (DEDP) to the Sponsor’s unique entry point (country-
specific contact details will be provided in the ISF). The Pregnancy Monitoring Form for 
Clinical Trials (Part A) should be used. 
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the Sponsor’s unique entry point on the Pregnancy Monitoring

As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE, 
only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form is to be 
completed. If there is an SAE associated with the pregnancy then the SAE has to be reported 
on the SAE form in addition. 
Similarly, potential drug exposure during pregnancy must be reported if a partner of a male 
trial participant becomes pregnant. This requires a written consent of the pregnant partner.
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and B), as 
well as information and consent form for the pregnant partner.

INVESTIGATIONAL PLAN
VISIT SCHEDULE
6.1
For a detailed overview of the trial procedures and time windows for visits, please refer to 
the Flow Chart.
The trial consists of a screening visit followed by a one year treatment period and 2 follow-
up visits.
The study will last until every evaluable entered patient has completed the last follow-up 
visit.
After giving his/her Informed Consent, the patient will be screened for inclusion and 
exclusion criteria for the study at visit 1. Visit 2 will be scheduled after visit 1, after results 
from central laboratory are obtained (a minimum of 7 days to be planned). The screening 
phase must not be longer than 4 weeks (from visit 1 to visit 2). The patient will be 
randomised at visit 2 if all inclusion and none of the exclusion criteria are fulfilled. 
Windows of ±1 to ±5 days is allowed for a majority of visits, to accommodate scheduling 
problems. If a delay is observed for a particular visit, the original calendar schedule should 
be kept for subsequent visits (delays should not accumulate). If a visit is missed the patient 
should be instructed to come for a visit as soon as possible. Investigator should contact the 
BI monitor to discuss further schedule.
Follow up visits have to be organized at 4 and 8 weeks after End of treatment

6.2.1
Screening and run-in period(s)
Screening Period
Written informed consent must be obtained before any protocol specific screening
assessments are performed.
The screening visit should take place within 7-28 days prior to randomization (Visit 2). All
study procedures and assessments including the repeated tests in determining the patient’s
eligibility must be available prior to Visit 2.
Patients must satisfy all inclusion and exclusion criteria prior to randomization (Visit 2).
Details of any patient who is screened for the study but is found ineligible must be entered in
an enrolment log (see ISF) and documented in the eCRF.
It is allowed to re-test (once) a lab parameter that is found abnormal at visit 1 if it is thought 
to be a measurement error (i.e. there was no abnormal result of this test in the recent history 
of the patient and there is no related clinical sign)”.

It is allowed to re-test the proteinuria if the result from spot ratio at screening visit does not 
correspond to recent measurements done at site. In that case it is preferred to do a 24h 
measurement.
For a detailed description of the trial procedures at the screening visit, refer to Flow Chart.
Baseline Conditions/Medical history:
As a precaution, risk factors for thromboembolic disease (including medical history of 
DVT/TE) should be specifically checked. If clinically relevant, the case should be discussed 
with the TCM/TMM prior to randomization. History of antiphospholipid syndrome should be 
recorded and patients should be excluded from the study.
Pregancy tests: 
Serum pregnancy test will be perfomed at screening visit. A urine dipstick test will be done 
during the screening phase and  immediately before starting medication. In case of a positive 
urine pregnancy test result, a blood sample for serum pregnancy test will be drawn for 
confirmation. Only those females with a negative pregnancy test will start treatment with 
MMF and will receive study medication.
6.2.2
Treatment period(s)
For details description of trial procedures during the treatment period, refer to Flow Chart.
Only additional critical information is listed below.
Eligible patients will be randomised to receive the first dose of study medication at Visit 2.
Each patient can only be randomised once in the trial via IRT.
Visit 2, 2.1, 2.2: drug administration:
The induction phase with SOC might have started for some patients already before the 
randomisation in the trial. 
-
MMF: if the patient is naïve with MMF or has received a dose < 2g/day, he will start 
receiving 2-3g/day MMF at visit 2
-
Intravenous Glucocorticoids: patients who have not yet received any high dose pulse 
IV steroids will receive 500 mg methylprednisolone for 3 days (visits 2, 2.1, 2.2). If 
considered necessary by the investigator, a maximal dose of 1000 mg 
methylprednisolone for 3 days is acceptable. In case the patient had already received 
pulse steroids (max 3g total within last 6 weeks) he will receive additional IV steroids 
only to reach 1.5g total. If the 1.5 g is reached the visit 2.1 and 2.2 are not necessary.

The investigator will prescribe daily oral steroids starting the day after the last IV steroids. 
Refer to section 4.2.1. This should be tapered down to 10 mg prednisone equivalent within 
12 weeks.
 drug injection:
For all other weekly injection, this can either be administered on-site or at home by the 
patient.
Urine collection:
At visit 2 and 11 and 16, 2 times 24h collection of urine will be performed. The patient will 
be given instructions and material to allow collection of urine during 2 days in the week
preceding the visit. At other time points, proteinuria will be assessed by spot urine.
Drug administration: 
According to the Flow Chart the patients will be receiving the syringes necessary for the next 
week(s) injection at home between two visits. The patients will be given instructions for 
injection and treatment number, and a diary to record the exact date and time of injection
At any visit, should a decision be made to discontinue the patient from study medication,
please complete EOT visit. 
6.2.3
Follow Up Period and Trial Completion
End of Treatment (EOT) Visit:
6.2.3.1
All patients will be asked to return for the EOT visit within 7 days from the last dose of study 
medication (either at week 52 for completers, or when a patient prematurely discontinues the 
drug). For details description of the trial procedures at EOT, refer to the Flow Chart. 2 times 
24h collection of urine has to be organized for this visit.
For patients that are eligible to participate in the extension trial 1293.13, the EOT visit will 
occur on the same day as the Visit 1 of the roll-over trial.
Follow-Up (FU) and End of Study (EOS) Visit:
6.2.3.2
After the end of treatment visit, patients who completed the 52 weeks treatment but are not 
eligible for the extension trial will return for a follow-up visit (after 4 weeks) and an EOS
visit, 8 weeks after EOT.

Patients who are eligible for the extension trial will not have to complete the FU visit nor the 
EOS visit, but only the trial completion page will have to be completed. 
During FU and EOS visits, the investigator will continue to follow-up on AEs that are not yet 
recovered. At EOS visit, the investigator needs to confirm whether the AEs are sufficiently 
followed up and provide documentation in the patient’s medical records and on the eCRF. 
For details description of the trial procedures at FU and EOS visits, refer to the Flow Chart.
Continuation of the study for patients who withdrew drug prematurely (before 
6.2.3.3
completion of the 52 weeks treatment):
In case a patient has to discontinue the trial drug, prior to having completed the 52 weeks 
treatment (i.e., prior to visit 16), he will be invited to attend a subset of visits as originally 
planned until and including visit 16: visit 5 (week 4), visit 8 (week 12), visit 11 (week 26), 
visit 14 (week 40) and an end of study visit at 52 weeks. During these visits, the patient 
should undergo selected examinations: physical examination, AE and CT collection, serum 
creatinine and spot urine test to assess the renal function. Other safety laboratory tests, PK 
sample, ADA, soluble protein biomarkers and anti-ds-DNA and complement will be 
collected at all visits until up to 12 weeks after End of Treatment. If the next FUP visit is 
planned more than 12 weeks after EOT, please have all optional tests performed at least once 
in the FUP period: i.e. if the patient EOT is V11 (W26), the next visit will be V14 (week 40): 
optional tests must be done at week 40, even if the time between week 26 &40 is >12 weeks.
The visits may continue even though the patient will be allowed to participate in another 
investigational study after his withdrawal (discontinuation plus 28 days). The need for visits 
in case of premature drug withdrawal will be explained to the patients. In case the patient 
discontinued more than 8 weeks before week 52, no further follow up would be needed after 
week 52. In case the patient discontinued less than 8 weeks before week 52, the last follow-
up visit will be 8 weeks +/- 5 days after discontinuation. In case the patient does not show-up 
at these visits, vital status information will be sought at planned EOS visit.

STATISTICAL METHODS AND DETERMINATION OF 
SAMPLE SIZE
STATISTICAL DESIGN - MODEL
7.1
This trial is a study of proof of concept in patients with lupus nephritis. It is designed as a 
randomized, double-blind and placebo-controlled trial with 4 parallel groups (3 active vs. 
placebo).
The primary objective of this trial is to define one or more suitable doses regarding efficacy 
and safety for further pivotal testing in Phase III. For this purpose a multiple comparison 
procedure with modelling (MCPmod) approach is considered (R10-1424, R15-1961).
NULL AND ALTERNATIVE HYPOTHESES
7.2
The primary endpoint is proportion of patients with complete renal response at week 52. The 
null hypothesis is that there is a flat dose response curve looking at the proportion of patients 
with complete renal response at week 52 in the placebo and the three BI 655064 dosage 
groups. The alternative hypothesis is that there is a non-flat dose response curve.
Additionally it will be investigated whether at least one dose shows a modelled absolute 
benefit compared to placebo of at least 10%.
The MCPMod procedure allows for the simultaneous evaluation of different potential dose 
response patterns, whilst protecting the overall probability of type I error of 20%. The pre-
specified models and their parameters used for this test are outlined in Section 7.3.1 and 
Section 7.7.
This is an exploratory trial and no formal statistical testing will be performed. Any p-values 
or confidence intervals provided are to be interpreted in an exploratory sense.
PLANNED ANALYSES
7.3
All the analyses will be performed in an exploratory fashion to better-understand the efficacy 
and safety profile of the drug under study in the selected patient population. The primary 
analysis will follow the intention to treat principle (ITT), thus it is based on the FAS (Full 
Analysis Set) and analysis will be performed as randomised. The FAS contains all treated 
patients who have a valid baseline value and at least one valid value in at least one primary 
or secondary efficacy endpoint on treatment.
Safety analysis will be based on all treated patients and the safety profile will be compared in 
a descriptive manner between the three experimental arms and the control arm.
All individual data will be listed. Adherence to the protocol (e.g. inclusion/exclusion criteria, 
times of measurement, completeness and consistency of data etc.) will be checked using the 
data recorded. Important protocol violations will be described I the TSAP. Standard 
statistical parameters (number of non-missing values, mean, standard deviation (SD), 
median, quartiles, minimum and maximum) or frequency tables will be calculated where

appropriate. In general, these parameters or frequencies will be calculated separately for each 
treatment group.
Data from subjects who are screened but not randomised will be listed but not included in 
any summary statistics.
7.3.1
Primary endpoint analyses
The primary endpoint is the proportion of patients with complete renal response after 52 
weeks of treatment. Patients withdrawn due to non-response are considered non-responders 
for the analyses at 52 weeks.
The analyses for PoC and dose-finding will be performed using MCPMod techniques (R10-
1424, R15-1961)for binary data whereby several possible dose response models (patterns) 
will be evaluated (while keeping full control of the type I error) to identify the best-fitting
model or subset of models. Due to the rareness of the disease and in order to have a feasible 
resulting sample size the global α-level has been chosen to be 20% one-sided.
A non-flat dose-response relationship is established if the null hypothesis of no dose effect 
(i.e. a flat dose response curve) is rejected for at least one of the pre-specified models with 
respect to the global alpha chosen.
For the sample size calculation, the maximum effect size is assumed to be 45% with the 
placebo effect size assumed to be 25%. Further details are given in Section 7.7.
The following models shapes have been selected as the candidate set of possible dose 
response patterns:
Emax : E0+Emax *d/(ED50 + d)]
Exponential : E0 + E1 * (exp(d/delta) - 1)
Quadratic : E0 + beta1 * d + beta2*d^2
Sigmoid Emax : E0 + Emax * d^h / (ED50^h + d^h)Model shapes are illustrated in figure 7-
3-1: 1. Note that the actual shapes are applied on the parameter scale (logit for binary data) 
according to Pinheiro et al. (R15-4293).

Figure 7.3.1 : 1: Shape of the models within the candidate set
If a non-flat dose response relationship is established, the significant model(s) from the 
above candidate set are refitted to the data without any parameter assumptions to generate 
new estimates of the model parameters from the data. The final model will be obtained via 
model averaging across the significant models based on Akaike Information Criterion (AIC). 
The target dose(s) can then be determined from that model by any incorporating information 
on the minimum clinically relevant effect as well as safety information. The target dose to be 
chosen should show a benefit of at least 10% in complete renal response rate at week 52 
compared to the placebo. This will be measured on the modelled efficacy and only doses 
within the dose range investigated (0mg-240mg) will be considered although the actual 
modelling will be performed on a broader range of doses including extrapolation.
If considered necessary and for the purpose of further model refinement, MCPMod might be 
repeated on the primary endpoint but with an extended set of shapes including the original 
candidates. Additionally to that covariates may be taken into account in a sensitivity analysis. 
Finally the approach described by Klingenberg et al (R15-0407) will be taken into account to 
show robustness of the primary analysis. Details of these analyses will be described in the 
TSAP.
Comparisons between treatment groups will be exploratory in nature and based on the 
numerical comparison of the respective response rates.  In addition, unadjusted absolute risk 
differences of the complete renal response at week 52 between the BI 655064 arms and the 
placebo group will be analysed. The proportion of responders in each arm, the risk difference

between each arm and placebo and 95% exact confidence intervals will be displayed. Finally, 
a logistic regression model on the proportion of patients with complete renal response at 
week 52 with factors treatment and race as strata will be applied. More details on the above 
analyses as well as additional sensitivity analyses will be given in the TSAP.
7.3.2
Secondary endpoint analyses
If considered necessary an MCPMod approach will also be applied to selected secondary 
endpoints.
Comparisons between treatment groups will be exploratory in nature and based on the 
numerical comparison of the respective response rates. In addition, unadjusted absolute risk 
differences of the response rates at week 52 between the BI 655064 arms and the placebo 
group will be analysed. The proportion of responders in each arm, the risk difference 
between each arm and placebo and 95% exact confidence intervals will be displayed.
Further details will be given in the TSAP.
7.3.4
Safety analyses
All treated patients will be included in the safety analysis. In general, safety analyses will be 
descriptive in nature and will be based on BI standards. No hypothesis testing is planned.
Adverse events will be coded using the Medical Dictionary for Regulatory Activities
(MedDRA) coding dictionary. Standard BI summary tables and listings will be produced. All 
adverse events with an onset between start of treatment and end of the residual effect period 
(REP), a period of 50 days after the last dose of trial medication, will be assigned to the 
treatment period for evaluation. Analysis will be performed based on randomised treatment.
Statistical analysis and reporting of adverse events will concentrate on treatment-emergent 
adverse events. To this end, all adverse events occurring between start of treatment and end 
of the residual effect period will be considered ‘treatment-emergent’.  The residual effect 
period is defined as 50 days. Adverse events that start before first drug intake and deteriorate 
under treatment will also be considered as ‘treatment-emergent’.
Frequency, severity, and causal relationship of adverse events will be tabulated by system 
organ class and preferred term after coding according to the current version of the Medical 
Dictionary for Drug Regulatory Activities (MedDRA).
Laboratory data will be analysed both quantitatively as well as qualitatively. The latter will 
be done via comparison of laboratory data to their reference ranges. Values outside the 
reference range as well as values defined as clinically relevant will be highlighted in the

listings. Treatment groups will be compared descriptively with regard to distribution 
parameters as well as with regard to frequency and percentage of patients with abnormal 
values or clinically relevant abnormal values.
Vital signs, physical examinations, or other safety-relevant data observed at screening, 
baseline, during the course of the trial and at the end-of-trial evaluation will be assessed with 
regard to possible changes compared to findings before start of treatment.
INTERIM ANALYSES
7.4
An interim analysis via an internal but independent team will be performed after all patients, 
complete 26 weeks of treatment. Alpha adjustments will not be made due to the exploratory 
nature of the assessment. At that timepoint, a preliminary database lock will be performed. 
The independent team will review all available unblinded safety, efficacy 
 This 
review is for internal planning purposes to facilitate further substance development. An 
interim analysis trial statistical plan will be written to define which functions will have 
access to the unblinded data. 
HANDLING OF MISSING DATA
7.5
As an imputation technique to deal with the missing data in this study, for the analysis of
primary and secondary endpoints, non-completers considered failure (NCF) will be used. All 
other endpoints will be analysed without imputing for any missing data.

RANDOMISATION
7.6
An IRT will be used for the assignment of subjects to treatment groups. Randomisation will 
be done with stratification by ethnicity (Asians vs Non- Asian) and proteinuria at screening 
<3g/day or ≥3g/day (respectively UP/UC<3 or UP/UC≥3)
. The influence of covariates (in particular with regard to Hispanics and Black / African-
Americans) will be analyzed in a sensitivity analyses.
Patients will be randomized in blocks to double-blind treatment. Patients will be randomized
to placebo and each treatment group in the following ratio 2:1:1:2 (approx. 40 patients 
allocated to placebo and 240mg, approx. 20 patients each to 120mg and 180mg). BI will 
arrange for the randomization and the packaging and labelling of trial medication. The 
randomization list will be generated using a validated system, which involves a pseudo-
random number generator so that the resulting treatment will be both reproducible and non-
predictable. The block size will be documented in the CTR. Access to the codes will be 
controlled and documented.
DETERMINATION OF SAMPLE SIZE
7.7
The aims of this study are two-fold. A first aim is to show a significant non-flat dose-
response curve across the different doses and placebo. Additionally to that at least one 
modelled dose within the dose range considered [0mg, 240mg] should show a benefit of at 
least 10% compared to placebo. 
Assumptions for the efficacy of the different doses are provided in the table below. 
Based on these assumptions and the planned sample size of 120 (=40:20:20:40) the success 
probability is approximately 82% for the base case of approximately 20% treatment benefit 
compared to placebo (45% vs 25% complete renal response rate at week 52). In case that 
there is only a minor treatment benefit the false success probability is basically limited by the 
α-level for the significance testing of the non-flat dose-response curve that is 20%.

Scenarios considered:

Expected A: Main scenario reflecting assumptions for efficacy of 25% (placebo), 30% 
(low dose), 38% (medium dose), 44% (high dose) and 45% (maximum efficacy). Sample 
size considered is 40:20:20:40=120 patients with a 2:1:1:2 allocation.

Expected B: Same scenario as A but for equal allocation and a larger sample size of 140 
total. Shows that ‘Expected A’ (unequal allocation) with 120 patients provides 
approximately the same success probability with 120 patients as ‘Expected B’ (equal 
allocation) with 140 patients.

Type I: Scenario reflecting almost no treatment benefit. Difference between maximum 
efficacy and placebo is 2% only (27%-25%). Shows that error probability is approx. 20% 
in such a case which is driven by the alpha for dose-response curve testing.

Shift: Same benefit of treatment to placebo in efficacy but with a shift of 20% in all 
assumed response rates. Shows that success probability is robust if actual response rates 
are quite different from ‘guesstimates’ given by ‘Expected A’ scenario.

Type 1 Shift: Shift scenario for very small treatment benefit of 2% only. Shows that still 
alpha drives error probability if actual response rates are quite different from 
‘guesstimates’.

Bad: Scenario with a low treatment benefit of 10% maximum compared to placebo. 
Represents a ‘worse-case’ scenario of treatment where treatment benefit is in a region 
where it is borderline efficacious.
Calculations were performed using R version 3.1.3.

in the Declaration of Helsinki, in accordance with the ICH Harmonized Tripartite Guideline 
for Good Clinical Practice (GCP) and relevant BI Standard Operating Procedures (SOPs) and 
the Japanese GCP regulations (Ministry of Health and Welfare Ordinance No. 28, March 27, 
1997).
Standard medical care (prophylactic, diagnostic and therapeutic procedures) remains in the 
responsibility of the treating physician of the patient.
The Investigator will inform the Sponsor immediately of any urgent safety measures taken to 
protect the trial subjects against any immediate hazard, and also of any serious breaches of 
the protocol or of ICH GCP*.
The rights of the Investigator and of the Sponsor with regard to publication of the results of 
this trial are described in the Investigator contract. As a rule, no trial results should be 
published prior to finalization of the Clinical Trial Report.
For japan: The rights of the investigator / trial site and of the sponsor with regard to 
publication of the results of this trial are described in the investigator contract / trial site’s 
contract. As a general rule, no trial results should be published prior to finalisation of the 
Clinical Trial Report.
The certificate of insurance cover is made available to the Investigator and the patients, and 
is stored in the ISF (Investigator Site File).”
TRIAL APPROVAL, PATIENT INFORMATION, AND INFORMED 
8.1
CONSENT
This trial will be initiated only after all required legal documentation has been reviewed and 
approved by the respective Institutional Review Board (IRB) / Independent Ethics 
Committee (IEC) and competent authority (CA) according to national and international 
regulations. The same applies for the implementation of changes introduced by amendments.
Prior to patient participation in the trial, written informed consent must be obtained from 
each patient (or the patient’s legally accepted representative) according to ICH / GCP and to 
the regulatory and legal requirements of the participating country. Each signature must be 
personally dated by each signatory and the informed consent and any additional patient-
information form retained by the Investigator as part of the trial records. A signed copy of 
the informed consent and any additional patient information must be given to each patient or 
the patient’s legally accepted representative.”
For Japan: The Investigator must give a full explanation to trial patients including the items 
listed below in association with the use of the patient information form, which is prepared 
avoiding the use of technical terms and expressions. The patient is given sufficient time to

about emergency code breaks. For drug accountability, refer to Section 4.1.8.
8.3.1
Source documents
Source documents provide evidence for the existence of the patient and substantiate the 
integrity of the data collected. Source documents are filed at the Investigator’s site.
Data reported on the eCRF must be consistent with the source data or the discrepancies must 
be explained. The Investigator may need to request previous medical records or transfer 
records, depending on the trial; current medical records must also be available.
All data must be derived from source documents
8.3.2
Direct access to source data and documents
The Investigator / institution will permit trial-related monitoring, audits, IRB / IEC review 
and regulatory inspection, providing direct access to all related source data / documents. 
eCRF and all source documents, including progress notes and copies of laboratory and 
medical test results must be available at all times for review by the Sponsor’s clinical trial 
monitor, auditor and inspection by health authorities (e.g. FDA). The Clinical Research 
Associate (CRA) / on site monitor and auditor may review all eCRF, and written informed 
consents. The accuracy of the data will be verified by reviewing the documents described in 
section 8.3.1.

LISTEDNESS AND EXPEDITED REPORTING OF ADVERSE EVENTS
8.4
8.4.1
Listedness
To fulfil the regulatory requirements for expedited safety reporting, the Sponsor evaluates 
whether a particular adverse event is "listed", i.e. is a known side effect of the drug or not. 
Therefore, a unique reference document for the evaluation of listedness needs to be provided. 
For the BI655064 this is the current version of the Investigator’s Brochure (U11-1925)
For non-investigational medicinal products the reference document are the SmPC for MMF 
and a representative SmPC for methylprednisolone (UK SmPC). The current versions of 
these reference documents are provided in the ISF. No AE are classified as listed for 
matching placebo, trial design, or invasive procedures.
8.4.2
Expedited reporting to health authorities and IEC / IRB
Expedited reporting of serious adverse events, e.g. suspected unexpected serious adverse 
reactions (SUSAR) to health authorities and IEC / IRB, will be done according to local 
regulatory requirements.
STATEMENT OF CONFIDENTIALITY
8.5
Individual patient medical information obtained as a result of this trial is considered 
confidential and disclosure to third parties is prohibited with the exceptions noted below. 
Patient confidentiality will be ensured by using patient identification code numbers.
Treatment data may be given to the patient’s personal physician or to other appropriate 
medical personnel responsible for the patient’s welfare. Data generated as a result of the trial 
need to be available for inspection on request by the participating physicians, the Sponsor’s 
representatives, by the IRB / IEC and the regulatory authorities.
END OF TRIAL
8.6
The end of the trial is defined as last patient out, which is when the last patient will have 
completed his/her 52 weeks treatment and the follow-up period (or has entered the extension 
trial). See section 6.2.3.
The IEC / competent authority in each participating EU member state needs to be notified 
about the end of the trial or early termination of the trial.
For japan: When the trial is completed, the Investigator should inform the head of the trial 
site of the completion in writing, and the head of the trial site should promptly inform the 
IRB and Sponsor of the completion in writing.

could be up to 21 days. Many patients may start 
induction therapy already before screening and the 
protocol allows up to 4 weeks between start of 
induction therapy and randomization. With a 
turnaround time of up to 21 days for the anti ds-
DNA test, patients who started induction therapy 2 
to 3 weeks before screening would not be able to 
participate in the trial. The criterion has been 
revised to allow more flexibility so that patients 
with positive anti ds-DNA diagnosed near the start 
of induction therapy can be included in the trial.

2.1 RATIONAL FOR PERFORMING THE 
TRIAL
Description of change
Rationale for SOC selection
There is no approved treatment for LN but the off-
label use of MMF or CYC is recommended by the 
ACR (R12-4273) and the EULAR/ERA-EDTA 
guidelines (R12-4921) and are therefore considered 
standard of care treatments. The efficacy of MMF-
and CYC-based induction therapy in LN is quite 
comparable (R15-3723 and R15-5330). For this 
trial, MMF-based SOC was selected based on 
feedback from international experts who in the 
majority presently recommend MMF. MMF is a 
non investigational product in this trial.

Rationale for SOC selection
There is no approved treatment for LN but the 
ACR (R12-4273) and the EULAR/ERA-EDTA 
guidelines (R12-4921) recommend the use of MMF 
or CYC in combination with glucocorticoids, 
starting with three consecutive pulses of 
intravenous (i.v.) methylprednisolone, and 
followed by oral glucocorticoids. The efficacy of 
MMF- and CYC-based induction therapy in LN is 
quite comparable (R15-3723 and R15-5330). For 
this trial, MMF-based SOC in combination with 
glucocorticoids with initial i.v. methylprednisolone 
pulse was selected based on feedback from 
international experts who in the majority presently 
recommend MMF. MMF and i.v. 
methylprednisolone are non investigational 
products in this trial.
Rationale for change
To clarify that the complete treatment regimen 
used as background medication is standard of care 
and not only MMF ; To clarify that IV 
methylprednisolone is also a Non Investigational 
Product in the trial

Description of change
The following Adverse events of special interest 
are added : 
Injection reactions including anaphylactic 
reaction
Any suspicion of severe injection reaction and of 
any potential cases of anaphylaxis should be 
defined and assessed using the criteria discussed in 
the statement paper from Sampson HA (R11-4890)
Cytokine release syndrome
A cytokine release syndrome manifests when a 
large number of immune cells becomes activated 
and releases inflammatory cytokines. It is 
consistently associated with elevated TNFα, IFNγ, 
and IL-6 levels. The cytokine-release syndrome is 
clinically characterized by fever, chills, rigor and 
rash. Other symptoms are nausea, dyspnoea, 
tachycardia and hypotension. Potentially life-
threatening complications of a cytokine release 
syndrome include cardiac dysfunction, respiratory 
distress syndrome, neurologic toxicity, renal and/or 
hepatic failure, and disseminated intravascular 
coagulation. In case of suspicion of a cytokine 
release syndrome, it is recommended to measure 
IL-6 levels in the local laboratory if the assay is

In general therapy with BI 655064 is 
immunosuppressive and potentially could increase 
the risk for infections or lymphoproliferative 
diseases.
Opportunistic infections and/or severe 
infections
Opportunistic infections include pneumocystis 
pneumonia, toxoplasmosa gondii encephalitis, 
cryptosporidiosis; microsporidiosis, 
mycobacterium tuberculosis, mycobacterium 
avium; bacterial respiratory disease, bacterial 
enteric infection, mucocutaneous candidiasis, 
invasive mycoses, CMV, EBV, herpes simplex, 
varicella zoster, human herpesvirus 8, JC virus 
infection. 
Any severe infection should also be reported as 
AESI.
Lymphoproliferative disorders (e.g. B- and 
T-cell lymphoma, Non-Hodgkin lymphoma 
and Hodgkin lymphoma, hepatosplenic T-
cell lymphoma)
In case of adenopathy, hepato- or 
splenomegaly, fever of unclear origin, night 
sweats or loss of weight, occurrence of 
lymphoproliferative diseases should be 
evaluated. As the occurrence of 
lymphoproliferative disorders is associated 
with active EBV-infection, patients 
suffering from active EBV infection should 
be carefully evaluated for the occurrence of 
lymphoproliferative diseases.Thrombosis 
and adjunct immunosuppression
Immunosuppression may favour a prothrombotic 
state. Therefore, patients should be carefully 
followed for early signs of peripheral or central 
thrombosis or thromboembolic events.

above mentioned Adverse Events please refer to

Visit 2.1 and 2.2 are necessary for IV steroids 
injections only. Refer to section 4.2.1. IV 
methylprednisolone injections to be done only to 
reach 1.5 g total dose within 6 weeks. If a higher 
dose of IV steroid is considered necessary by the 
investigator a total dose of up to 3g is acceptable.
Rationale for change
Based on feedback from some investigators, a 
higher dose of iv steroids is sometimes considered 
to be necessary for initial induction treatment. This 
is in line with the ACR guideline for treatment of 
Lupus Nephritis which recommends iv pulses of 
500 mg to 1000 mg.
In addition it was realized that the time window of 
4 weeks is sometimes too narrow to allow 
participation of patients who otherwise would 
fulfill all In-and Exclusion criteria. Based on 
feedback from the Coordinating investigator, it is 
not expected that neither the extension to 6 weeks 
not the higher iv. steroid dose will have an impact 
safety or on the response at week 52 weeks which 
is the primary endpoint of the study.

while maintaining a level of homogeneity to better 
assess treatment effect in this Phase 2 study. High 
dose steroids have significant impact on the short 
term response and have potentially relevant side 
effects. To keep the population included in the trial 
more homogenous and to avoid increased risk of 
side-effects, the total amount of i.v. steroids has to 
be limited. A total amount of 1.5 g is the maximum

increase the steroid dose for the patient. These 
patients are allowed to continue treatment with BI 
655064 until week 52
Rationale for change
Clarify the use of glucocorticosteroids
Section to be changed
4.2.1
Description of change
Sentence deleted: “For the primary analysis, these 
patients will be looked upon as failures”
Rationale for change
The protocol allows some flexibility for the use of 
glucocorticosteroids, in no place addition of 
glucocorticosteroids to the recommeneded dose 
would lead to discontinuation. This drug can be 
administrated for other reason than treatment of 
lupus nephritis. Therefore for patient’safety, 
consistencies, and to avoid misunderstandings, the 
sentence is deleted.

Rationale for change
The reason of deletion of the sentence is that it was 
misleading. This restriction is not included in the 
primary endpoint definition. It is also not included 
in the statistical part (section 7).
During the trial, patients could need steroids for 
other reason than Lupus Nephritis (including 
emergency situation), therefore some flexibility 
must be possible for the investigator to treat 
adequately the patient. This is also done in other 
trials in this field.
Details on how to handle steroid dosing and 
responder’s patients will be clarified in TSAP.
