Brief summary:
This trial designed to evaluate the toxicity and efficacy of tocilizumab in the treatment of steroid refractory acute graft versus host disease (GVHD).

Detailed description:
Patients who underwent an allogeneic hematopoietic stem cell transplantation, with biopsy proven GVHD, active acute GVHD requiring systemic immune suppressive therapy and that failed or did not respond to first line of therapy (corticosteroids ± other agent).

Tocilizumab will be administered intravenously at a dose of 8 mg/kg once every three weeks. Patients with documented responses will continue to receive treatment at 8 mg/kg once every 3 weeks for at least two months (day 56). Patients that have some degree of response but without complete resolution of signs and symptoms of acute GVHD may continue to receive 8 mg/kg on a 3-week cycle until complete response is achieved or lack of further improvement. In patients who are beyond day 56 and whose GVHD has resolved, the dose of Tocilizumab will be reduced to 4 mg/kg every 3 weeks. Subsequent discontinuation of Tocilizumab will occur once patients are off other immune suppressive medications (including extracorporeal photopheresis, ECP) or are receiving sub therapeutic levels of immunosuppression (i.e., Tacrolimus (FK) levels \<5 ng/mL) or prednisone dose \<20 mg/day (or equivalent) and are free of acute GVHD signs or symptoms for at least one month.

Patients who fulfill criteria of progression of GVHD not in the setting of immunosuppressive taper, no response of GVHD or require initiation of other immune suppressive treatment for GVHD will have Tocilizumab discontinued.

Tocilizumab shall be discontinued and not re-instituted if any one of the following criteria is met. The patient will be taken off study drug therapy at that point, but still followed for primary and secondary study endpoints. A response assessment will be made at the time of therapy discontinuation and at subsequent defined study endpoints. The patient will not be replaced on study. Follow-up data will be required unless consent for data collection is withdrawn:

* Additional systemic GVHD therapy is added for disease progression or non-response
* Steroid dose is escalated to ≥ 2.5 mg/kg/day of prednisone (or methylprednisolone equivalent of 2 mg/kg/day) for GVHD progression or no response
* Development of toxicity that requires withholding of study medication for more then 14 days

1.0 BACKGROUND AND RATIONALE 
 
Graft versus host disease (GVHD) is the major complication associated with allogeneic stem cell 
transplantation.  A prominent characteristic of GVHD is the presence of a proinflammatory 
milieu that is attributable to conditioning regimen-induced host tissue damage as well as 
secretion of inflammatory cytokines [e.g. interleukin-1 (IL-1), tumor necrosis alpha-α (TNF-α), 
interferon-γ (IFN-γ), interleukin-6 (IL-6)] by alloactivated donor T cells and other effector cell 
populations.1-3 These cytokines perpetuate GVHD through direct cytotoxic effects on host 
tissues,4-6 activation and/or priming of immune effector cells,7 and differentiation of 
proinflammatory T cell populations (i.e. TH1 and TH17 cells) from naïve T cell precursors.8,9  
This inflammatory environment is also promoted by the absence of an effective regulatory T cell 
(Treg) response as both a relative and an absolute decline of Tregs in the peripheral blood and 
target tissues has been demonstrated in a majority of studies.8,10-12 The strong association 
between a proinflammatory milieu and the absence of an effective counter regulatory response 
suggests that the inflammatory environment prevents and/or inhibits Treg reconstitution during 
GVHD.  How this occurs, however, is not well understood.  
 
IL-6 is a pleiotrophic cytokine that is produced by a variety of cell types, including T cells, B 
cells, fibroblasts, endothelial cells, monocytes and keratinocytes.13 IL-6 is of particular interest 
with respect to GVHD biology since it occupies a unique position at the crossroads where the 
fate of naïve T cells to become either regulatory cells or proinflammatory T cells is determined.  
In the presence of IL-6 and transforming growth factor-β (TGF-β), naïve T cells differentiate 
into TH17 cells, whereas in its absence these same cells are induced to become Tregs.14,15  
Furthermore, IL-6 produced by dendritic cells after activation through Toll-like receptors is able 
to inhibit the suppressive function of natural Tregs.16,17 Thus, IL-6 appears to have a pivotal role 
in directing the immune response towards an inflammatory phenotype and away from a 
regulatory response. The potential importance of IL-6 in GVHD is also supported by clinical 
studies that have shown that patients with elevated plasma levels of IL-6,18,19 as well as those 
with a recipient or donor IL-6 genotype that results in increased IL-6 production,20,21 have an 
increased incidence and severity of GVHD.   
 
Signaling through IL-6 occurs by the binding to a low affinity IL-6 receptor (IL-6R) which 
together induces homodimerization of gp130 and subsequent transduction of the intracellular 
signal.22 This membrane-bound IL-6R, however, is expressed only on hepatocytes and 
hematopoietic cells.  Notably, the IL-6R can also be shed from the membrane generating a 
soluble form of the receptor which can complex with IL-6 and induce an intracellular response in 
cells that lack the membrane-bound IL-6R through a process called trans-signaling.23,24  
Interference with the actions of IL-6 by administration of an IL-6R antibody that prevents 
binding of the cytokine to its receptor has been shown to be effective in the treatment of a variety 
of inflammatory disease such as rheumatoid arthritis,25,26 amyloidosis,27 and colitis.28 
 
Tocilizumab (Actemra) is a humanized anti-IL-6 receptor antibody that blocks IL-6 signaling 
and has been FDA-approved for the treatment of severe active rheumatoid arthritis.  It has been 
shown to have remission-inducing efficacy in patients with moderate to severe rheumatoid 
arthritis, systemic juvenile idiopathic arthritis, and multicentric Castlemans’ disease.  A pilot 
phase I/II study in patient with active Crohn’s disease also suggested benefit when administered

on an every two week basis.29 Recent studies in a murine model of GVHD, has shown that 
treatment with an anti-IL-6R antibody is able to significantly reduce GVHD-associated mortality 
and pathological damage.30 One of the mechanisms by which this occurs is through the enhanced 
reconstitution of regulatory T cells that express the transcription factor foxp3.  Reconstitution of 
both natural and induced Tregs has been demonstrated in animals treated with this antibody, 
suggesting that the increase in overall numbers of Tregs is responsible, in part, for the 
attenuation in GVHD severity. A recent case report demonstrated that administration of 
tocilizumab was effective at significantly reducing the severity of GVHD in the GI tract as 
determined by a marked reduction in the volume of diarrhea.31  Notably, this patient had failed 
multiple prior therapies, including high dose steroids, infliximab, budesonide, photopheresis, 
sirolimus, and mycophenolate mofetil.  This report provides further support for the premise that 
this agent may be an effective therapy for steroid resistant GVHD.

2.0 STUDY DESIGN 
 
2.1 Study Design 
 
This is a phase I-II trial designed to evaluate the toxicity and efficacy of tocilizumab in the 
treatment of steroid refractory acute GVHD.    
 
2.2 Primary Objective 
 
The primary objective of the study is to determine the response rate (complete and partial) at day

3.0 TREATMENT SCHEME 
 
3.1 Tocilizumab Dose  
 
Tocilizumab will be administered intravenously at a dose of 8 mg/kg once every three weeks. 
Patients with documented responses will continue to receive treatment at 8 mg/kg once every 3 
weeks for at least two months (day 56). Patients that have some degree of response but without 
complete resolution of signs and symptoms of acute GVHD may continue to receive 8 mg/kg on 
a 3-week cycle until complete response is achieved or lack of further improvement. In patients 
who are beyond day 56 and whose GVHD has resolved, the dose of Tocilizumab will be reduced 
to 4 mg/kg every 3 weeks. Subsequent discontinuation of Tocilizumab will occur once patients 
are off other immune suppressive medications (including extracorporeal photopheresis, ECP)or 
are receiving sub therapeutic levels of immunosuppression (ie. FK levels< 5 ng/mL) or 
prednisone dose <20mg/day (or equivalent) and are free of acute GVHD signs or symptoms for 
at least one month.    
 
Patients who fulfill criteria of progression of GVHD not in the setting of immunosuppressive 
taper, no response of GVHD or require initiation of other immune suppressive treatment for 
GVHD will have Tocilizumab discontinued. 
 
3.2 Corticosteroid Taper 
 
It is anticipated that all patients will be on corticosteroids at the time of initial Tocilizumab 
administration. Patients who are responding to Tocilizumab may have steroids tapered at the 
discretion of the primary physician. Similarly, patients treated with steroids but deemed not to 
have had a response to this agent may also be tapered if the primary physician deems that longer 
term steroid administration may place the patient at unacceptable risk of opportunistic infection. 
However, for those improving, steroid taper should not start sooner than 72 hours after 
administration of tocilizumab and the steroid dose must not be tapered to less than 0.25 
mg/kg/day prednisone (or 0.2 mg/kg/day methylprednisolone) on Day 28.  
 
3.3 Acute GVHD Flare 
 
If acute GVHD flares during taper of prednisone, the dose of corticosteroids may be increased at 
the discretion of the treating physician as long as this increase is to less than 2.5 mg/kg/day of 
prednisone (or methylprednisolone equivalent of 2 mg/kg/day), as in this case it will be 
considered adding a “new agent” and the patient will be scored as a failure. 
 
3.4 Concurrent Immune Suppressive Medications 
 
Patients should remain on concurrent immune suppressive medications at the time that treatment 
with Tocilizumab is initiated.  Patients that are deemed to be responding to Tocilizumab may 
have their other immune suppressive medications tapered or discontinued as clinically indicated 
(also see above section on corticosteroid taper).

3.5 Discontinuation Criteria 
 
Tocilizumab shall be discontinued and not re-instituted if any one of the following criteria is met.  
The patient will be taken off study drug therapy at that point, but still followed for primary and 
secondary study endpoints.  A response assessment will be made at the time of therapy 
discontinuation and at subsequent defined study endpoints.  The patient will not be replaced on 
study.  Follow-up data will be required unless consent for data collection is withdrawn: 
• Additional systemic GVHD therapy is added for disease progression or non-response 
• Steroid dose is escalated to ≥ 2.5 mg/kg/day of prednisone (or methylprednisolone 
equivalent of 2 mg/kg/day) for GVHD progression or no response 
• Development of toxicity that requires withholding of study medication for more than 14 
days (see Section 2.5 for details of dose modifications for toxicity)

4.0 PHARMACEUTICAL INFORMATION 
 
4.1 Study Agent: Actemra® (Tocilizumab) 
 
Classification: Immunomodulator 
 
4.2 Clinical Pharmacology: 
 
Tocilizumab is a recombinant humanized interleukin-6 receptor inhibiting monoclonal antibody. 
Tocilizumab binds to both soluble and membrane bound IL-6 receptors and results in the 
blockade of interleukin-6 signaling through these receptors. 
 
4.3 Pharmacokinetics 
 
Pharmacokinetic studies indicate that tocilizumab undergoes biphasic elimination from the 
circulation.  In rheumatoid arthritis patients treated with 4 and 8 mg/kg every 4 weeks, the 
central volume of distribution was 3.5 L and the peripheral volume of distribution was 2.9 L 
with a volume of distribution at steady state of 6.4 L.  Tocilizumab dosed at 8 mg/kg resulted in 
a mean steady state area under the curve (AUC), minimum concentration (Cmin) and a 
maximum concentration (Cmax) of 35 + 15 mg∙hr/ml, 9.74 + 10.5 mcg/ml and 183 + 85.6 
mcg/ml respectively.  Tocilizumab AUC, Cmin and Cmax increased with increasing body 
weight with a 86% higher exposure in patients greater than 100 kg.  As a result, doses 
exceeding 800 mg (max dosing weight 100 kg) per infusion are not recommended. 
 
The total clearance of Tocilizumab is concentration-dependent and is represented by the both the 
linear clearance and the nonlinear clearance.  Upon saturation of the non-linear clearance 
pathway, the main determining factor is linear clearance.  The reported linear clearance in the 
pharmacokinetic studies is estimated to be 12.5 mL/h.  The concentration dependent half-life is 
up to 11 days for the 4 mg/kg dose and up to 13 days for the 8 mg/kg dose every 4 weeks at 
steady state. 
 
4.3.1 Special populations 
 
Pharmacokinetic analysis in adult rheumatoid arthritis patients did not demonstrate a change in 
kinetics based on age, gender or race. The effects of renal and hepatic impairment have not been 
assessed.  
  
4.4 Drug supply and storage 
 
Tocilizumab is commercially available. Single use vials containing Tocilizumab, preservative 
free, sterile concentrate solutions (20 mg/ml) for IV infusion are available in the following sizes:  
80 mg, 200mg, and 400 mg. The solution is colorless to pale yellow, with a pH of approximately 
6.5. 
 


Tocilizumab in Acute GVHD 
Protocol version 6.0 (01/15/2016) 
 
 
9 
 
Vials should be stored under refrigeration at 2°C to 8°C (36°F to 46°F).  Do not freeze.  Protect 
the vials from light by storage in the original package until time of use.  Inspect vials visually for 
particulates and discoloration prior to use and discard if particulates or discoloration is noted. 
   
4.5 Administration: 
 
Tocilizumab will be administered at the initial dose of 8 mg/kg with a maximum dosing weight 
of 100 kg (max dose 800 mg) and 4mg/kg for maintenance. The infusion will be administered 
over 60 minutes through a dedicated IV line every 3 weeks as clinically indicated.  Do not 
administer by IV bolus.   
 
4.5.1 Preparation 
 
Using aseptic technique, utilize a 100 ml bag of 0.9% sodium chloride injection USP and 
withdraw a volume equal to the volume of the tocilizumab solution required for the dose.  Next, 
withdraw the calculated volume of tocilizumab solution necessary for the dose from the vials and 
slowly inject the tocilizumab to the infusion bag.  The final solution volume should be 100ml.  
Gently invert the IV bag to mix the solution.  Inspect the prepared IV solution for particulates. 
 
4.5.2 Storage of prepared IV solution 
 
The solution may be stored under refrigeration or at room temperature for up to 24 hours and 
should be protected from light. 
 
Patients may remain on existing immunosuppressive regimen at the time tocilizumab is begun 
but no additional agents can be added unless patient is deemed to have failed treatment (see 
evaluation of response). 
 
4.6 Warnings / Precautions 
 
4.6.1 Serious infections 
 
The product information labeling contains a black box warning regarding the risk of serious 
infection. Most patients who developed these infections were taking concomitant 
immunosuppressants such as Methotrexate or corticosteroids.  Serious infections leading to 
hospitalization or death, including tuberculosis, bacterial, invasive fungal, viral and other 
opportunistic infections have occurred in patients receiving tocilizumab. Viral reactivation and 
cases of herpes zoster exacerbation were reported in clinical trials.   It is recommended that 
patients are tested for latent tuberculosis before and during use of tocilizumab.  If a serious 
infection develops, Tocilizumab should be withheld until the infection is controlled. 
 
4.6.2 Gastrointestinal Perforations 
 
Events of GI perforation have been reported in clinical trials, primarily as complications of 
diverticulitis.  Patients presenting with new onset abdominal symptoms should be evaluated 
promptly.

Protocol version 6.0 (01/15/2016) 
 
 
10 
 
 
4.6.3 Laboratory Parameters 
 
Neutropenia, decreases in platelets, transaminase elevations, and increases in lipid parameters 
(total cholesterol, LDL and triglycerides) have been reported in relation to the use of 
tocilizumab. 
 
4.6.4 Hypersensitivity reactions 
 
Anaphylaxis and infusion reactions have been reported in association with tocilizumab infusions.  
Appropriate medical treatment should be available for immediate use in the event of an 
anaphylactic reaction during administration. 
 
4.7 Adverse effects: 
 
Other adverse reactions most frequently reported in clinical trials include upper respiratory tract 
infections, nasopharyngitis, headache, hypertension, ALT increases, dizziness, bronchitis, rash, 
mouth ulceration, upper abdominal pain, and gastritis.  Anti-tocilizumab antibodies have been 
detected in a small number (2% of patients). Hypersensitivity (allergic) reactions including a few 
cases of anaphylaxis have also been reported. 
 
4.8 Drug interactions: 
 
Elevated levels of IL-6 and other cytokines have been associated with reduced expression of 
some cytochrome (CYP) P450 enzymes.  Tocilizumab, through IL-6 inhibition, has the potential 
to affect expression of multiple CYP enzymes by restoring their activity to a higher level than 
that in the absence of tocilizumab.  Monitoring of drugs that are metabolized by CYP’s with 
narrow therapeutic index or where the dose is individually adjusted is advised.  Caution should 
be exercised when tocilizumab is co-administered with CYP3A4 substrate drugs where decrease 
in effectiveness is undesirable, e.g., oral contraceptives, atorvastatin etc.  The effect of 
tocilizumab on CYP450 enzymes may occur within approximately 2 weeks of starting therapy 
and persist for several weeks after stopping therapy.  
 
 
4.9 Supportive Care Guidelines 
 
4.9.1 Infectious Disease Monitoring  
Patients on tocilizumab should have CMV PCR NAAT,  EBV, HHV6, and Adenovirus testing 
by PCR in the blood prior to each dosing of tocilizumab. Viral testing may be performed more 
frequently if clinically indicated. 
 
Anti-infective prophylaxis against herpes viruses, Pneumocystis jiroveci, bacterial and fungal 
infections should be followed according to standard MCW institutional practices. 
 
 
 


Tocilizumab in Acute GVHD 
Protocol version 6.0 (01/15/2016) 
 
 
11 
 
4.9.2 Laboratory monitoring 
Patients on Tocilizumab require weekly evaluations of liver enzymes (AST, ALT, Bilirubin) for 
the first two cycles of treatment. After two cycles, hepatic evaluation should be done at the 
discretion of the treating physician and at least once before each dose of Tocilizumab.  
 
Fasting* lipid profile including total cholesterol, low density lipoprotein (LDL) and triglycerides 
should be done at baseline and before each dose of Tocilizumab for the first three doses. If no 
significant increases in lipid profile, they should be repeated every 6 months thereafter for 
monitoring. *If patient is on TPN a non-fasting lipid profile is acceptable. 
 
Patients on calcineurin inhibitors (cyclosporine, tacrolimus) or rapamycin should have the levels 
checked at least twice week after the first dose of Tocilizumab for at least three weeks. 
 
Patients who are on concurrent potentially myelosuppressive agents (e.g. gancyclovir) may 
need more frequent monitoring of WBC. 
 
4.10 Toxicities and guidelines for dose reduction/withholding study drug 
4.10.1  Hepatic Dysfunction 
This refers to increases observed after the institution of Tocilizumab. 
Liver enzyme abnormality 
(ALT, AST,) 
Recommendation 
> 1 to 3 x baseline 
(A).  For patients in whom the AST and ALT 
are within the normal range at the onset of 
enrollment into the study, the upper limit of 
normal for each enzyme will be used to 
determine whether the patient’s LFTs are 
greater than one to three times the normal 
values.  For persistent increases in this range 
for 2 consecutive weeks after the most recent 
dose of Tocilizumab, in the absence of any 
other offending hepatic toxic agents, reduce 
dose to 4 mg/kg.   
(B).  For patients in whom the baseline LFTs 
were elevated outside of the upper limit of the 
normal range at the time of enrollment, these 
values will serve as the baseline for the 
calculation of whether the LFTs are >1 to 3 
times normal.  For persistent increases in this 
range, defined as AST and ALT both elevated 
>1 to 3X baseline for 2 consecutive weeks 
after the most recent dose of Tocilizumab, in 
the absence of any other offending hepatic 
toxic agents, reduce dose to 4 mg/kg. 
 
> 3 to 5 x baseline 
 
Hold therapy for 1 week. Discontinue any 


Tocilizumab in Acute GVHD 
Protocol version 6.0 (01/15/2016) 
 
 
12 
 
other offending hepatic toxic agent, if 
possible. Recheck labs. If AST and ALT still 
elevated >3 to 5 x baseline, continue to hold 
for 
additional 
week. 
Determination 
of 
baseline LFT values will be made as noted 
above for LFTs > 1 to 3X baseline.  Resume 
drug when hepatic function returns to < 3 x 
baseline then follow recommendations for > 1 
to 3 x baseline by reducing dose to 4 mg/kg. 
If no improvement after a total of 2 weeks of 
holding therapy and no other offending 
hepatotoxic agent can be implicated, then 
discontinue Tocilizumab. If there is a 
contributing hepatotoxic agent that cannot be 
discontinued and which is thought to have 
been responsible for increase in LFTs, then 
Tocilizumab may be continued at reduced 
dose of 4 mg/kg for one additional dose at 
physician’s discretion. If no further increase 
in LFTs > 3 to 5 x baseline, continue 
Tocilizumab at 4 mg/kg. If LFTs increase to > 
5 x baseline, discontinue therapy. 
 
 
 
 
4.10.2 Neutropenia 
 
ANC 
Recommendation 
<1000 
intervening 
period 
between doses 
If ANC <1000, then may give G-CSF to 
increase

at 
physician 
discretion. 
Remove other offending agents that might 
lower ANC if possible.  If ANC >1000 at 
time of next dose and patient does not require 
sustained G-CSF administration to maintain 
ANC>1000, then reduce Tocilizumab to 4 
mg/kg for this and subsequent doses.  If 
patient is still requiring daily G-CSF 
administration then physician may at his /her 
discretion elect to hold for an additional week 
to determine whether ANC>1000 can be 
achieved without requirement of sustained G-
CSF administration. 
 
< 1000at time of next dose,  
If ANC remains <1000 at time of next dose 
hold dose for 1 week, administer G-CSF if not 
previously done, and re-check. If ANC

Protocol version 6.0 (01/15/2016) 
 
 
13 
 
remains <1000, hold 1 additional week, and 
continue G-CSF.  If  ANC not >1000 after 
second week of holding dose,discontinue 
Tocilizumab. 
 
 
 
 
 
 
4.10.3 Infection 
Patients with severe or refractory infections may have Tocilizumab held at the attending 
physician's discretion.  Antibody can be reinstituted when the infection episode is controlled and

4.10.4 Other Unexpected Toxicities: 
Study drug may  be held for other CTCAE v.4 Grade 3-4 toxicities that are considered probably 
related to Tocilizumab at the discretion of the treating physician.

5.0 GUIDELINE FOR SERIOUS ADVERSE EVENT REPORTING  
 
5.1 Definitions 
Adverse Event - Any untoward medical occurrence in a patient or clinical investigation subject 
administered a pharmaceutical product, medical treatment or procedure and which does not 
necessarily have to have a causal relationship with this treatment. An adverse event can 
considered therefore be any unfavorable and unintended sign (including an abnormal laboratory 
finding, for example), symptom, or disease temporally associated with the use of a medicinal 
product, medical treatment or procedure whether or not related to the medicinal product. 
  
Life-threatening Adverse Event – Any adverse event that places the patient or subject, in view 
of the investigator, at immediate risk of death from the reaction. Study toxicities are graded using 
the adapted NCI Common Toxicity Criteria (where appropriate use the criteria for transplant 
patients.)  
  
Unexpected Adverse Event – An adverse event that was not described in the study protocol or 
informed consent. 
  
• Serious Adverse Event (SAE) – Any adverse event occurring that results in any of the 
following outcomes: 
• Death – days 0-200, regardless of cause. 
• life-threatening adverse event (see above). 
• persistent or significant disability/incapacity. 
• congenital anomaly. 
• requires intervention to prevent permanent impairment or damage. 
   
Attribution - The designation for the determination of whether an adverse event is related to a 
medical product, treatment or procedure will be as follows: 
• Related – includes adverse events that are definitely, probably, or possibly related to the 
medical treatment or procedure. 
• Not Related – includes adverse events are doubtfully related or clearly not related to the 
medical treatment or procedure. 
  
The MCW Serious Adverse Event (SAE) Report Form should be completed for all adverse 
events that meet the expedited reporting requirements  
  
Serious adverse events that do not meet the requirement for expedited reporting (not related to 
study treatment or expected) will be reported to the IRB as part of the annual renewal of the 
protocol.    
 
5.2 Monitoring the Progress of Trial and the Safety of Participants 
  
This Phase I/II clinical trial will be monitored by the Medical College of Wisconsin Cancer 
Center Data Safety Monitoring Committee (DSMC) and the principal investigator (PI), William 
R Drobyski MD.  The PI will review the outcome of the data for each individual patient on an 
ongoing basis. The PI of the study will have primary responsibility for ensuring that the protocol 
is conducted as approved by the Institutional Review Board. The PI will ensure that the 


Tocilizumab in Acute GVHD 
Protocol version 6.0 (01/15/2016) 
 
 
15 
 
monitoring plan is followed and that all data required for oversight of monitoring are accurately 
reported, that all adverse events are reported according to the protocol guidelines, and that any 
adverse reactions reflecting patient safety concerns are appropriately reported. Study toxicities 
are graded using the adapted NCI Common Terminology Criteria for Adverse Event (CTCAE) v 
4.0 (where appropriate, use the criteria for transplant patients.)  
5.3 Reporting of Adverse Events 
  
The adverse event reporting in this clinical trial will follow an adapted version of the MCW 
Guidelines for SAE reporting. These guidelines detail the expedited reporting requirements, 
definitions of particular events. All severe adverse events (SAEs), which are defined as an event 
that occurred during or following the administration of Tocilizumab to a subject during the 
course of the study that resulted in death, considered life threatening, required inpatient 
hospitalization or prolonged existing hospitalization, resulted in persistent disability, congenital 
anomaly or events judged as medically important,  meeting the MCW expedited reporting 
criteria will be reported to the MCW Institutional Review Board (IRB) within 3 days by the PI or 
research coordinator upon learning of the event.  For patients being cared for at Froedtert 
Hospital, health care providers communicate with the PI or research coordinator as events occur 
triggering subsequent reporting. For patients not being cared for at Froedtert Hospital, the 
outside facilities communicate with the PI, or research coordinator for these reporting purposes. 
Toxicities contributing to and meeting the study stopping rule criteria will be reported to the IRB 
within 3 days of study staff awareness. All other SAEs and deaths, not meeting the expedited 
reporting criteria, will be submitted to the IRB as part of the annual continuation review report to 
the IRB.    
 
5.4 Expedited Reporting Requirements 
 
All unexpected and serious adverse events meeting MCW expedited reporting criteria 
which may be due to study procedures or intervention must be reported to the MCW IRB 
as soon as possible but within at least 3 calendar days of the investigator learning of the 
event. 
 
Any deaths that occur within 60 days of treatment will be immediately reported to the 
DSMC and MCW IRB. 
 
 All Grade 4 (life-threatening) toxicities occurring between days 0-200 after the administration of 
the first dose of Tocilizumab that meet MCW expedited reporting requirements must be reported 
as soon as possible but within at least 3 calendar days of the investigator learning of the event.

6.2 Response Definitions 
 
Complete response is defined as a CIBMTR score of 0 for the GVHD grading in all evaluable 
organs.  For a response to be scored as a CR at day 56 or later the participant must still be in CR 
on that day and have had no interfering additional therapy for an earlier progression, PR or NR. 
 
Partial response is defined as improvement in one or more organs involved with GVHD 
symptoms without progression in others.  For a response to be scored as PR at day 56 or later, 
the participant must still be in PR on that day and have had no interfering additional therapy for 
an earlier progression, PR or NR 
 
Mixed response is defined as improvement in one or more organs with deterioration in another 
organ manifesting symptoms of GVHD or development of symptoms of GVHD in a new organ.   
 
Progression is defined as deterioration in at least one organ without any improvement in others, 
or development of signs and symptoms of chronic GVHD.. 
 
No response is defined as follows.  Patients receiving additional immune suppressive therapy 
will be classified as nonresponders. If acute GVHD progresses (new organ involvement or 
increased organ specific symptoms sufficient to increase the organ stage by one or more) after at 


Tocilizumab in Acute GVHD 
Protocol version 6.0 (01/15/2016) 
 
 
17 
 
least 7 days of study drug administration, or if there is no response (no reduction in any GVHD 
organ staging) after 7 days of study drug administration, administration of the study drug may be 
discontinued, and the patient may be treated with alternative secondary GVHD therapy at the 
discretion of the treating physician. 
 
6.3 Primary Endpoint 
 
The primary endpoint is proportion of CR/PR at Day 56 of therapy.  CR is defined as resolution 
of all signs and symptoms of GVHD in all evaluable organs in comparison to Day 1 scoring.  
For a response to be scored as CR at Day 56, the participant must still be in CR on that day and 
have had no intervening salvage therapy for an earlier progression, PR or NR. 
 
6.4 Secondary Endpoints 
 
6.4.1 Proportion of Partial Response (PR), Mixed Response (MR), No Response (NR) and 
Progression:  
 
Proportion of Complete Response (CR), Partial Response (PR), Mixed Response (MR), No 
Response (NR) and Progression among surviving patients at Day 56:  Scoring of CR, PR, MR, 
NR and progression are in comparison to the participant’s acute GVHD status (score) on Day 0 
of the study. 
 
6.4.2 Proportion of Primary Treatment Failures 
 
No response, progression, administration of additional therapy for GVHD, development of sign 
and symptoms of chronic GVHD or mortality by Day 14 post-initiation of treatment will be 
considered a primary treatment failure. 
 
6.4.3 GVHD Flares  
 
Flares are defined as any progression of acute GVHD after an initial response (i.e., earlier CR or 
PR) that requires re-escalation of steroid dosing, or initiation of additional topical or systemic 
therapy.  While all “flares” will be captured, only flares that require additional systemic therapy 
(that is additional drugs) or re-escalation of steroids to ≥ 2.5 mg/kg/day of prednisone [or 
methylprednisolone equivalent of 2 mg/kg/day] will be counted as failure for the primary 
endpoint.  The rate of all flares before Day 90 will be examined as a secondary endpoint. 
 
6.4.4 Immunosuppression Discontinuation 
 
Discontinuation of immunosuppression will be assessed by Day 56, Day 180 and Day 360 after 
enrollment.  The date of discontinuation of corticosteroids will be recorded.  In addition, dates 
for discontinuation of all other systemic immunosuppressive medications (where applicable), 
including cyclosporine or tacrolimus, sirolimus, etc. for treatment or prevention of acute GVHD 
will be captured.

6.4.5 Chronic GVHD 
 
The incidence of chronic GVHD at 6 months after enrollment will be examined. 
 
6.4.6 Overall Survival 
 
Overall survival at Day 180 will be computed. 
 
6.4.7 Incidence of Toxicities 
Incidence of serious adverse events and grade 3-5 CTACAE v4 at day 56 after initiation of 
Tocilizumab will be summarized.   
  
6.4.8 Incidence of Infections 
The incidence of definite and probable  viral, fungal and bacterial infections will be tabulated 
after initiation of tociluzumab.  
 
6.4.9 Disease-free Survival at 6 and 12 Months Post-randomization 
 
Disease-free survival at 6 months will be computed.  The events for disease-free survival are 
death and relapse of the underlying malignancy. 
 
6.4.10 Non-relapse Mortality at 6 and 12 Months Post-randomization 
 
Non-relapse mortality at 6 months will be computed.  The events for non-relapse mortality are 
death due to any cause other than relapse of the underlying malignancy.

5 Fasting lipid profile including total cholesterol, low density lipoprotein (LDL) and triglycerides should be done at baseline 
and before each dose of Tocilizumab for the first three doses. If no significant increases in lipid profile, they should be 
repeated every 6 months thereafter for monitoring. Lipid panel need not be repeated if baseline lipid panel has been done 
within 7 days of starting first dose of Tocilizumab. *If patient is on TPN a non-fasting lipid profile is acceptable.

8.0 STATISTICAL CONSIDERATIONS 
This study is a single arm phase I/II study designed to assess the safety and efficacy of tocilizumab 
for treatment of steroid resistant acute GVHD.  Historical data indicates that approximately 25% of 
steroid resistant patients respond to second or third line therapy.  The study is designed as a two-
stage trial according to the Simon optimal design with 80% power to detect an increase in the 
response rate at day 56 from 25% to 50%, using a 10% one-sided type I error rate.  This design will 
require a total sample size of 21 patients, with 8 patients enrolled in the first stage.  If 2 or fewer of 
the first 8 patients respond, the study will be stopped for futility.  Otherwise, if 8 or more of the 21 
total patients respond, the treatment will be considered sufficiently promising.  This study design 
has a 68% chance of stopping after the first 8 patients, if the response rate is 25%, and an 80% 
chance of considering the treatment promising if the response rate is 50%. 
Stopping Rules 
 
Deaths in the first 28 days will be monitored.  A mortality probability of >20% in the first 
month is unexpected and the protocol team would want to review the protocol should this 
rate be exceeded.  Entry of patients into the trial will stop while the protocol and deaths are 
reviewed if there is significant evidence that the day 28 overall mortality rate is more than 
20% based on the exact binomial test.  The stopping rule is summarized in the following 
table.

The testing procedure for overall mortality within 28 days rejects the null hypothesis in favor of 
the alternative 10% of the time when the true 28 day mortality is 20%, and 85% of the time when 
the rate is 45%.  This corresponds to a type I error rate of α = 0.10 and a type II error rate of β = 
0.15.  When the true 28 day mortality rate is 45%, on average, the stopping rule will be triggered 
19 months after opening, when 5 events have been observed in 11 patients. 
 
1.1. Analysis of Secondary Endpoints 
 
1.1.1. Proportion of CR, PR, MR, NR and Progression  
 
Proportions of Complete Response (CR), Partial Response (PR), Mixed Response (MR), No 
Response (NR) and Progression at Days 28 and 56 will be compared between the treatment 
groups using the chi-square test.   
 
1.1.2. Proportion of Primary Treatment Failures among Surviving Patients 
 
Proportion of primary treatment failures among surviving patients at Days 28 and 56 will be 
compared using the Z test for comparing binomial proportions. 
 
1.1.3. GVHD Flares Requiring Additional Therapy 
 
The proportion of patients experiencing a flare after an initial response will be evaluated at Day 
90 and compared between treatment groups using the Z test for comparing binomial proportions.  
This will be done both for all flares as well as flares that require additional systemic therapy.   
 
1.1.4. Immunosuppression Discontinuation 
 
The incidence of discontinuation of immunosuppression will be computed separately in each 
treatment group using the cumulative incidence curve, with death prior to discontinuation as the 
competing risk.  Pointwise 95% confidence intervals will be provided at Day 56, Day 180, and 
Day 360.  Comparison of the cumulative incidence curves between treatment will be done using 
Gray’s test.   
 
1.1.5. Cumulative Steroid Dose at Day 56 after treatment 
 
The median and range of cumulative steroid doses at each time point will be provided separately 
for each treatment group.  The median cumulative steroid dose will be compared between 
treatment groups using the Wilcoxon rank sum test.   
 
1.1.6. Chronic GVHD 
 
The incidence of chronic GVHD will be computed using the cumulative incidence estimator, 
treating death prior to chronic GVHD as a competing risk.  Pointwise confidence intervals will 
be provided at 6 and 12 months, and the cumulative incidence curves will be compared using 
Gray’s test.

Protocol version 6.0 (01/15/2016) 
 
 
25 
 
 
1.1.7. Overall and GVHD-free Survival 
 
Overall survival will be computed using the Kaplan-Meier estimator.  Pointwise confidence 
intervals will be provided at Days 180 and 360.  Survival curves will be compared between 
treatment groups using the log-rank test.  GVHD-free survival will be estimated using simple 
proportions of patients alive and without GVHD if there is no censoring prior to 180 or 360 days.  
If there is censoring, the proportion of patients alive and without GVHD will be estimated in 
each treatment using multi-state model techniques.i   
 
1.1.8. Disease-free Survival at 6 Months Post-treatment 
 
Disease-free survival will be estimated using the Kaplan-Meier method, treating death or relapse 
of malignancy as events in patients with malignancies.  This outcome will be compared between 
the two treatment groups using the log-rank test. 
 
1.1.9. Non-relapse Mortality at 6 Months Post- treatment 
 
Non-relapse mortality will be estimated using the cumulative incidence method, treating relapse 
as the competing risk.  The cumulative incidence curves for non-relapse mortality will be 
compared between the treatments using Gray’s test.

You are invited to take part in this research study. This form tells you why this research 
study is being done, what will happen in the research study, possible risks and benefits 
to you, your choices, and other important information. If there is anything that you do not 
understand, please ask questions. Then you can decide if you want to join this study or 
not.   
 
A1. INTRODUCTION – WHY ARE WE ASKING YOU ABOUT THIS STUDY? 
You are being invited to participate in this research study because you have been 
diagnosed with acute Graft Versus Host Disease (GVHD) that has not responded to 
steroid treatment. 
 
A total of about 21 people are expected to participate in this study at the Medical 
College of Wisconsin/Froedtert Hospital. 
 
The Director of the study is William Drobyski, MD in the Department of Medicine, 
Division of Hematology and Oncology. A study team works with Dr. Drobyski. You can 
ask who these people are.  
 
A2. DO I HAVE TO BE IN THIS STUDY? 
You can decide whether to take part in this study or not. You are free to say yes or no. If 
you say no, your regular medical care will not change. Even if you join this study, you do 
not have to stay in it. You may stop at any time.  
 
A research study is different from routine medical care in three ways: 1) there are extra 
risks that we will tell you about in this form; 2) you may have some extra medical tests 
and visits; 3) the study procedures, tests and visits follow a set plan that must be kept.

A3. WHY IS THIS RESEARCH STUDY BEING DONE? 
In this study we want to find out whether treatment with a drug called tocilizumab can be 
effective in people with acute GVHD that have not responded to treatment with steroids. 
We want to find out whether the new drug, tocilizumab, reduces the symptoms of acute 
GVHD, and whether it causes any problems (side effects). Everyone in this study will 
receive tocilizumab which is approved by the U.S. Food and Drug Administration for use 
in patients but not with your condition.  We are testing tocilizumab to see what effect it 
has on people with acute GVHD. We do not know all the ways that this drug may affect 
people. We don’t know if this study will help you. Your condition may get better but it 
could stay the same or even get worse. We hope the information from this study will 
help us develop a better treatment for acute GVHD in the future. 
 
B1. WHAT WILL HAPPEN IF I TAKE PART IN THE STUDY?   
Before you begin the study 
 
First we will need to find out whether you are able to be in the study. You will be asked 
to give information about your medical history and undergo the exams and tests listed 
below.  
 
Physical exam including an assessment of your GVHD 
 
Blood tests to evaluate your organ function  
 
Blood and urine tests to check for the presence of infectious diseases 
 
During the study 
You may receive the study drug, tocilizumab (8 mg/kg), every three weeks for 8 weeks 
(56 days) to determine if you have had a response. If you are responding to the study 
drug but your symptoms have not completely resolved, you will continue to receive the 
same dose every 3 weeks.  If your symptoms have resolved, you will receive 
tocilizumab once every 3 weeks at a reduced dose of 4 mg/kg until you have been 
taken off all other medicines that suppress your immune system. 
 
 
The following tests and exams will be done every three weeks for the first 8 weeks while 
receiving tocilizumab: 
 Physical exam 
 Assessments of your GVHD 
 Blood tests to check for infectious diseases. 
 Blood tests to evaluate your organ function (weekly during the first 3 weeks, then 
once every three weeks) 
 If clinically indicated, blood cultures to check for bacteria and fungus.

After Day 56, if you are still receiving Tocilizumab, the following tests and exams will be 
done every 3 weeks until one year after study entry, or until discontinuation of 
Tocilizumab:   
 Physical exam 
 Assessments of your GVHD 
 Blood tests to evaluate your organ function  
 Blood tests to check for infectious diseases 
 
B2. HOW LONG WILL I BE IN THE STUDY? 
You will be in this research study for about 12 months. There is a small possibility that 
you may be on the study longer if your disease continues to respond but has not 
completely resolved by 12 months 
 
B3. CAN I STOP BEING IN THE STUDY?   
You are free to withdraw from the study at any time. If you leave, your regular medical 
care will not change. If you are thinking about leaving, please tell the study doctor.  
 The doctor can tell you about the effects of stopping, and you and the doctor can talk 
about what follow-up care would help you the most. 
 You might be asked to come back for additional visits to check your health. 
 
The study doctor may take you out of this study at any time. This would happen if: 
 
They think it is in your best interest. 
 
You do not follow the study rules. 
 
The whole study is stopped. 
If this happens, the study doctor will tell you. 
 
C1. WHAT HEALTH RISKS OR PROBLEMS CAN I EXPECT FROM THE STUDY? 
There are risks to taking part in any research study. There is a risk that you may get 
drug that does not help your condition or may make it worse.  There also may be 
problems (side effects) we do not know about yet, from the drug itself, or how it 
combines with other drugs you are taking. If we learn about new important side effects, 
we will tell you.  
 
We watch everyone in the study for problems (side effects). You need to tell the study 
doctor or a member of the study team immediately if you experience any 
problems, side effects, or changes in your health.   
 
C2. RISKS OF TOCILIZUMAB  
The research drug itself may cause problems (side effects).  Side effects may be mild or 
very serious.  Some can last a long time or never go away or cause death.  
 
The side effects that other people have experienced so far with the tocilizumab are:  
 
More common 
 upper respiratory tract infections

 inflammation of the nasal passages (nasopharyngitis) 
 headache 
 high blood pressure (hypertension) 
 dizziness 
 bronchitis 
 rash 
 mouth sores  
 upper abdominal pain  
 inflammation of the lining of the stomach (gastritis) 
 decreases in white blood cells 
 decreases in platelets 
 increases in liver enzymes in the blood 
 increases in cholesterol (total cholesterol, LDL and triglycerides)  
 
Serious infection 
There is a risk of serious infection that could lead to death. Most patients who 
developed these infections were also taking drugs that suppress the immune system 
such as Methotrexate or corticosteroids.  Serious infections leading to hospitalization or 
death, including tuberculosis, bacterial, invasive fungal, viral and other opportunistic 
infections have occurred in patients receiving tocilizumab. Viral reactivation and cases 
of herpes zoster exacerbation were reported in clinical trials.    
 
Gastrointestinal (GI) Perforations 
Events of GI perforation have been reported in clinical trials, primarily as complications 
of diverticulitis.  Please contact your doctor if you have any new symptoms affecting 
your abdomen. 
 
Hypersensitivity (allergic) and infusion reactions 
o Sometimes mild to moderate allergic reactions may happen, such as 
hives, itching and skin rash.  Severe or life-threatening allergic reactions, 
even death, although rare, may also happen.  If you do have an allergic 
reaction, medical treatment will be given to you.  
 
C5. ARE THERE ANY BENEFITS TO TAKING PART IN THE STUDY? 
We don’t know if this study will help you. Your condition may get better but it could stay 
the same or even get worse. We hope the information from this study will help us 
develop better treatments for Graft Versus Host Disease. 
 
D1. ARE THERE ANY COSTS TO BEING IN THE STUDY? 
Most of the medical care that you will receive in this study is considered routine care for 
your condition and would be recommended whether you join the study or not.  Costs for 
routine care will be billed to you or your insurance carrier. Some insurers will not pay for 
drugs, tests or hospitalization that are part of research studies, so check with your 
insurer before you join this study.

The billing of the study drug will be handled differently if you have Medicare. If you have 
Medicare, the study drug, tocilizumab, will not be billed to Medicare. The study drug will 
be provided to you at no charge; however, you will be responsible for all copays.  
 
If you do not have Medicare, a prior authorization will be conducted with your insurance 
company to determine if the cost of the study drug, tocilizumab, will be covered by your 
insurance. If your insurance does not cover the cost of the study drug it will be provided 
at no charge; however, you will be responsible for all copays and deductibles. 
 
If you have questions regarding study costs or if your insurance status changes, please 
contact Dr. Drobyski 
 
D2. WILL I BE PAID FOR PARTICIPATING IN THE STUDY? 
There is no payment for being in this study. 
 
D3. WHAT OTHER HEALTHCARE CHOICES DO I HAVE? 
You do not have to join this study. You are free to say yes or no. If you do not join this 
study, your doctor can discuss other healthcare choices with you.  
Your other choices may include: 
 
using other medications that suppress your immune system to treat your graft 
versus host disease 
 
D4. WILL I BE GIVEN NEW INFORMATION ABOUT THE STUDY? 
If we learn any important new information about the drug that might change your mind 
about being in the study, we will tell you about it right away.  You can then decide if you 
want to stay in the study.

E3. What are the risks of sharing this health information? 
One risk of taking part in a research study is that more people will handle your personal 
health information collected for this study. The study team will make every effort to 
protect the information and keep it confidential, but it is possible that an unauthorized 
person might see it. Depending on the kind of information being collected, it might be 
used in a way that could embarrass you or affect your ability to get insurance. If you 
have questions, you can talk to the study doctor about whether this could apply to you.

If you sign this form, we plan to keep your information indefinitely in case we need to 
check it again for this study. 
 
E5. Can I cancel my permission to share this health information? 
If you change your mind later and do not want us to collect or share your health

decide that you cannot continue to be part of the study. We may still use the information 
we have already collected.
