PROTOCOL SUMMARY
Study Title: A Phase 1 Study of MLN9708 in Japanese Patients With Relapsed and/or 
Refractory Multiple Myeloma
Study Phase: 1
Indication: Patients with relapsed and/or refractory multiple myeloma
Study Objectives: 
Primary: 
• To evaluate the tolerability, safety, and pharmacokinetics of MLN9708 alone or in 
combination with lenalidomide and dexamethasone (Rd) in patients with relapsed and/or
refractory multiple myeloma.
Secondary: 
• To evaluate the antitumor activity of MLN9708 in patients with relapsed and/or 
refractory multiple myeloma.
Overview of Study Design:  
This study consists of the following 4 cohorts.
• Cohort 1: MLN9708 4.0 mg
• Cohort 2: MLN9708 4.0 mg + Rd
• Cohort 3: MLN9708 5.5 mg
• Cohort 4: MLN9708 5.5 mg + Rd
Three subjects will be enrolled sequentially from cohort 1 (MLN9708 4.0 mg alone). If dose-
limiting toxicity (DLT) occurs in one subject during DLT-assessment period, 3 additional 
subjects will be enrolled in the same applicable cohort to evaluate the tolerability in a total of 6
subjects. If DLT occurs in 2 of the 3 subjects, the given dosage is considered intolerable. If 
DLT occurs in 2 of the 6 subjects, the sponsor will determine the tolerability to the given dosage
after discussing with the Efficacy and Safety Evaluation Committee (ESEC).
The sponsor will evaluate the tolerability of MLN9708 dosage on the basis of the safety data 
including DLT incidences during the DLT-assessment period.  The sponsor will decide whether 
the next cohort will be studied and the dose of the next cohort in consultation with the ESEC, if 
necessary. If the current cohort is considered tolerable, the next cohort will be in the order of 
cohorts 2 (MLN9708 4.0 mg plus Rd), 3 (MLN9708 5.5 mg alone), and 4 (MLN9708 5.5 mg 
plus Rd).  Even if a dosage is considered tolerable and transition to the next cohort is 
considered feasible, the next cohort may not be studied based on the results of the overseas 
clinical studies and the current study.  
The additional written informed consent for extended treatment will be obtained before the first 
dose of MLN9708 in Cycle 2 from the subjects who meet the criteria in “6.4 Criteria for 
Beginning the Next Cycle of Treatment“ and have no safety concern. Subjects who do not give
the consent will undergo end of study (EOS) visit on 29 days after the last dose of MLN9708 in 
Cycle 1. The subjects giving the consent can continue the study treatment up to 12 cycles 
unless they meet the criteria in “8.1 Removal of Subjects” including evidence of progressive 
disease (PD) and intolerable toxicity. Subjects may remain on treatment after the 12 cycles if 
the investigator considers it beneficial for the subjects.
All subjects should undergo end of study visit on 29 days after the last dose of MLN9708.
The overall study design is described in “Study Design and Treatment Schema”.

BACKGROUND AND RATIONALE
1.1
Multiple myeloma
Multiple myeloma is a disease in which the plasma cells proliferate monoclonally in the 
bone marrow and become malignant (myeloma cells). Multiple myeloma gets its name 
because the myeloma cells infiltrate the bone marrow and form tumors in multiple 
locations. Humoral factors such as cytokines that are produced by the interaction of the 
bone marrow interstitial cells with the myeloma cells and monoclonal immunoglobulin 
(M-protein), which is produced by the myeloma cells, result in complications such as 
bone marrow failure, bone destruction, hypercalcemia, and renal failure. Multiple 
myeloma frequently occurs in the elderly. In the US, it is the second-leading hematologic 
malignancy: approximately 5 to 7 new cases of multiple myeloma are diagnosed per 
100,000 people each year (this works out to approximately 20,000 people total), and 
11,000 people die of malignant myeloma each year (accounting for about 2% of all 
cancer deaths). The situation is similar in Europe (Jemal et al, 2005; NCCN Guidelines, 
Version 1, 2012). In Japan, approximately 2 to 3 new cases of multiple myeloma are 
diagnosed per 100,000 people each year, and the total number of patients with multiple 
myeloma is estimated to be 13,000 (MHLW 2008 Patient Survey). In 2009, the number 
of deaths due to multiple myeloma was 4,084 in all (2,089 males and 1,995 females), 
meaning that multiple myeloma accounted for 1.2% of all cancer deaths (National Cancer 
Center, Center for Cancer Control and Information Services, Cancer Statistics in Japan 
2010). In Japan, multiple myeloma is treated in virtually the same way as in the US and
Europe. In the US and Europe, diagnosis and treatment guidelines have been 
promulgated by the NCCN, the British Committee for Standards in Haematology, and the 
UK Myeloma Forum. The NCCN Guidelines (Version 1, 2012) recommend a treatment 
regimen that includes bortezomib or an immunomodulator (thalidomide or lenalidomide) 
in the frontline setting. Patients deemed eligible for autologous stem cell transplants 
(ASCT) subsequently receive ASCT with high-dose chemotherapy. Bortezomib, 
thalidomide, lenalidomide, and other antitumor agent combination therapies are listed as 
salvage therapies. In Japan, the Japanese Society of Myeloma Guidelines (Version 2) 
issued in 2008, and these guidelines recommend almost the same treatments as those 
recommended in the US and Europe.

Although treatments involving thalidomide, bortezomib, lenalidomide, and ASCT with 
high-dose chemotherapy have yielded better results – the 5-year survival was 25% in 
1975, but rose to 34% in the period from 1999 to 2005 (NCCN Guidelines, Version 1, 
2012). However, most patients, both in Japan and in other countries, experience re-
exacerbation during treatment. Salvage therapies are only effective in the short term; in 
the end, the patients stop responding to treatment. New and better drugs are therefore 
needed.
1.2
MLN9708
MLN9708 is an inhibitor of the 20S proteasome currently under development by 
Millennium Pharmaceuticals, Inc (MPI) in the United States. Inhibition of the 20S 
proteasome has been validated as a therapeutic target for the treatment of malignancies by 
the efficacy of the first-in-class proteasome inhibitor, bortezomib (Velcade®) in multiple 
myeloma and other hematologic malignancies. MPI has been developing MLN9708 for 
the better efficacy, safety, and convenience of bortezomib. 
MLN9708 is the citrate ester of the biologically active dipeptide boronic acid, MLN2238.
In aqueous solution or in blood, MLN9708 rapidly hydrolyzes to MLN2238, the active 
form that selectively and reversibly inhibits the proteasome. Similar to bortezomib, 
MLN2238 binds the β5 subunit of the 20S proteasome; however, it has a shorter 
dissociation half-life than bortezomib which contributes to wide distribution to tissues, 
and expected to demonstrate stronger antitumor activity. Nonclinical study showed 
greater antitumor activity against various xenograft models compared to bortezomib. 
MLN9708 has been formulated for both intravenous (IV) and oral (PO) administration, 
and oral formulation is used for development for multiple myeloma.
1.3
Nonclinical Studies 
MLN9708 is primarily examined as MLN2238 in the nonclinical studies since MLN9708 
rapidly hydrolyzes to the active form, MLN2238 after dosing.

1.3.1
Pharmacology
There are several features of MLN2238, such as sustained pharmacodynamics effects and 
activity in bortezomib-refractory lymphoma xenograft models, that suggest it may have 
activity that extends beyond that seen with bortezomib.
1.3.1.1
In Vitro Pharmacology
MLN2238 inhibits β5 site 20S proteasome activity in vitro, with a concentration 
producing 50% inhibition (IC50) of 3.4 nmol/L Potency is reduced roughly 10-fold 
versus β1 (IC50= 31 nmol/L) and 1,000-fold versus β2 (IC50 = 3,500 nmol/L). MLN2238 
was also tested for inhibition against a panel of 103 kinases, 18 receptors 
(neurotransmitter, ion channel, brain and gut receptors), and 9 serine proteases. In all 
cases, the IC50 values were ≥10 µmol/L. Furthermore, MLN2238 demonstrated potent 
cell growth inhibition activity against MDA-MB-231 human breast cancer cells.
1.3.1.2
In Vivo Pharmacology
To determine the activity of MLN2238 in vivo, pharmacodynamics studies were 
performed in immunocompromised mice bearing either CWR22 human prostate or WSU-
DLCL2 (human diffuse large B-cell lymphoma) tumors. In CRW22 xenografts, there 
was a clear dose response seen in both tumor 20S proteasome inhibition and in changes 
in the protein markers of proteasome inhibition (GADD34 and ATF-3). In WSU-DLCL2 
xenografts, increased expression of protein markers of proteasome inhibition was resulted 
with MLN2238, and observed greater tumor proteasome inhibition compared to 
bortezomib. MLN2238 demonstrated stronger antitumor activity in 3 human lymphoma 
xenograft models including WSU-DLCL (as compared to bortezomib). In the case of the 
CWR22 xenograft model, significant antitumor activity was seen with both IV and PO 
dosing.
1.3.2
Pharmacokinetics
The pharmacokinetic properties of MLN2238, the active form of MLN9708, were studied 
in severe combined immunodeficient (SCID) mice bearing human CWR22 tumor 
xenografts, Sprague-Dawley rats, beagle dogs, and cynomolgus monkeys. Because of the

extensive red blood cell (RBC) partitioning of MLN2238, both blood and plasma 
pharmacokinetic parameters were determined in these studies. MLN2238 had a very low 
blood clearance (CLb) and a moderate blood volume of distribution at steady-state (Vss,b) 
after IV administration. The concentration-versus-time curve of MLN2238 displayed a 
distinct biexponential profile with a steep initial distribution phase and a long terminal 
elimination half-life (t1/2) (>24 hours) in all species tested. MLN2238 had higher plasma 
clearance (CLp) and a larger plasma Vss (Vss,p) than in CLb and Vss, b, largely because of 
the extensive RBC partitioning.
The pharmacokinetic properties of MLN2238 after oral administration were studied in 
rats and dogs. The plasma oral bioavailability was 41% in rats and nearly 100% in dogs. 
A clinical prototype formulation of the MLN9708 capsule demonstrated that MLN2238 
had excellent oral bioavailability and an excellent absorption profile in dogs. In addition, 
interindividual variability (coefficient of variation) in maximum plasma concentration 
(Cmax) and area under the concentration versus time curve from 0 to 24 hours (AUC0-24hr) 
after PO administration was low to moderate, similar to that after IV administration. The 
terminal t1/2 after oral administration was also similar to that after IV administration.
Metabolism appears to be a major route of elimination for MLN2238 and urinary 
excretion of the parent drug was negligible (< 5% of dose). In vitro study demonstrated 
that MLN2238 was metabolized by multiple cytochrome P450 (CYP) isozymes and non-
CYP enzymes and proteins. The rank order of relative biotransformation activity of each 
of the 5 major human CYP isozymes was 3A4 (34.2%) >1A2 (30.7%) >2D6 (14.7%) 
>2C9 (12.1%) >2C19 (negligible). All metabolites found in human liver microsome 
studies were also found in rat and dog liver microsomal studies, supporting the use of rats 
and dogs as appropriate species for toxicology studies. MLN2238 is neither an inhibitor 
of CYP isozymes 1A2, 2C9, 2C19, 2D6, and 3A4 (IC50 >30 µM, with an estimated 
inhibition dissociation constant [Ki] >15 µmol/L), nor a time-dependent inhibitor of 
CYP3A4/5 (up to 30 µmol/L). The potential for MLN9708 treatment to produce DDIs 
via CYP inhibition is inferred to be low. However, there may be a potential for DDIs 
with a concomitant strong CYP3A4 or CYP1A2 inhibitor or a strong CYP3A4 inducer 
because of the possible contribution of CYP3A4- and CYP1A2-mediated metabolism to 
the elimination of MLN9708 in humans.

MLN2238 may be a low-affinity substrate of para-glycoprotein (P-gp), breast cancer 
resistance protein (BCRP), and multidrug resistance protein 2 (MRP2). MLN2238 
however is not an inhibitor of P-gp, BCRP, and MRP2 transporters (IC50 > 100 µmol/L).
Consequently, the potential for MLN2238 to cause DDIs with substrates or inhibitors of 
P-gp, BCRP, and MRP2 is low.
1.3.3
Safety Pharmacology
In exploratory safety pharmacology studies, MLN2238 was a weak inhibitor of the 
cloned cardiac potassium (K+) human ether à-go-go-related gene (hERG) channel, with 
an IC50 of 59.6 µM, which exceeds, by approximately 200-fold, the plasma Cmax
(111 ng/mL [0.3 µM]) predicted to occur in humans at the optimally efficacious dose 
after IV administration.
In the Good Laboratory Practice (GLP) compliant, 1-cycle, repeat-dose, PO toxicology 
study in beagle dogs, an increase in corrected QT interval (QTc) was seen in male dogs at 
nontolerated doses, and a potential increase in QTc was seen in male dogs at tolerated 
doses. However, increased QTc was not seen in female dogs at any dose, despite the fact 
that female dogs had plasma Cmax values similar to those of male dogs. Additionally, in a 
GLP-compliant, 2-cycle, repeat-dose, IV toxicology study in beagle dogs, no increase in 
QTc was seen in either male or female dogs at any dose, even though dogs in the IV study 
had higher plasma MLN2238 concentration values than did the male dogs in the PO study. 
These data suggest that MLN2238 has a low potential for prolonging the QT interval in 
vivo. In the GLP-compliant, repeat-dose toxicology studies in beagle dogs, no effects on 
clinical signs or physical examination findings indicative of impaired respiratory or CNS 
function were noted at tolerated doses ( ≤ 0.14 mg/kg) after IV or PO administration. 
Detailed neurologic examinations MLN2238-related changes in neurologic parameters, 
primarily observed as changes in mental status (very low arousal) and changes in gait 
(ataxia) were observed at nontolerated doses (≥ 0.18 mg/kg). Similar findings were not 
observed at tolerated doses with any consistency.

MLN2238 was not mutagenic in a GLP-compliant bacterial reverse mutation assay 
(Ames assay).
1.3.4.2
In Vivo Toxicology
After repeated IV and PO administration of MLN2238, the exposures that were tolerated 
in rats were similar to those tolerated in dogs, indicating similar species sensitivity. The 
target tissues for dogs and rats were similar and consisted of the bone marrow, peripheral 
ganglia, and intestines. Higher exposures were achieved in the IV study compared to the 
PO study, and it is likely that the differences seen in peripheral white blood cell counts 
and bone marrow hypocellularity between the 2 studies reflected differences in exposure 
and not differences in toxicologic response after PO versus IV administration. Similarly, 
the lower exposures achieved after PO versus IV administration likely account for the 
lack of peripheral nervous system effects seen in the PO study. The toxicologic effects 
seen in rats (bone marrow hypocellularity with corresponding thrombocytopenia and 
neutropenia, degeneration of peripheral ganglia with secondary degeneration of 
peripheral nerves and spinal cord dorsal column, intestinal mucosal hyperplasia, and 
hepatocellular hypertrophy and vacuolization) are qualitatively similar to what was 
observed previously in rodents treated with bortezomib.

Clinical Experience
No clinical studies evaluating MLN9708 have been conducted in Japan to date. Safety, 
tolerability, pharmacokinetics, and disease response are assessed in 7 phase 1 or phase 
1/2 studies (Table 1-1). IV and PO administration are being evaluated with a weekly and 
a twice-weekly dosing schedule. MLN9708 is given on Days 1, 8, and 15 of a 28-day 
cycle in the once weekly dosing schedule, and the drug is given on Days 1, 4, 8, and 11 of 
a 21-day cycle in the twice-weekly dosing schedule. As of 12 October 2011, preliminary 
data have been obtained from 247 subjects enrolled across 7 ongoing studies.

Clinical Studies in Relapsed or Refractory Multiple Myeloma
Two ongoing clinical trials, Studies C16003 and C16004, investigate single-agent 
MLN9708 in patients with relapsed or refractory multiple myeloma.
In Study C16003 (0.24, 0.48, 0.80, 1.20, 1.68, 2.23 mg/m2; twice-weekly), 56 patients 
were enrolled as of 12 October 2011 and received treatment for 1 to 28 cycles (median,
3.5 cycles). One patient achieved complete response, 5 patients achieved a partial 
response, and 29 patients achieved minor response. 
In Study C16003, 1 of 3 patients experienced a protocol-defined DLT (Grade 3 rash) at a 
dose of 2.23 mg/m2, and an additional patient at this dose experienced Grade 4 
thrombocytopenia at DLT. The intermediate dose of 2.0 mg/m2 was set as a new dose

group approximately half way between the 2 existing dose levels of 2.23 mg/m2 and 
1.68 mg/m2. Given that none of the 6 patients treated at the 2.0 mg/m2 group experienced 
a DLT, the maximum tolerated dose (MTD) of MLN9708 administered twice weekly was 
determined to be 2.0 mg/m2.
Overall, 98% of patients experienced a treatment-emergent adverse event. Peripheral 
neuropathy was limited to Grade 1 or 2 in 10% of patients; with all of these patients 
reporting baseline Grade 1 peripheral neuropathy at study entry. The most common 
(≥20%) treatment-emergent adverse events are shown in Table 1-3.

patients were enrolled as of 12 October 2011 and received treatment for 1 to 11 cycles 
(median, 2 cycles). One patient achieved a VGPR and one patient achieved a PR.
In Study C16004, 2 of 3 patients experienced protocol-defined DLT (Grade 3 rash, Grade

Clinical Studies in Patients With Newly Diagnosed Multiple Myeloma
Two ongoing clinical trials of Studies C16005 and C16006 in patients with newly 
diagnosed multiple myeloma are currently ongoing.
In Study C16005 where MLN9708 is administered weekly (1.68, 2.23, 2.97, and 
3.95 mg/m2) in combination with lenalidomide and dexamethasone (Rd), 15 patients have 
been enrolled as of 12 October 2011 and completed 1 to 9 treatment cycles (median, 5
cycles). No DLTs were seen at doses up to 2.23 mg/m2. Three of 3 patients treated at the 
3.95 mg/m2 dose cohort experienced Grade 3 nausea and vomiting despite adequate 
antiemetic therapy; one of which additionally experienced Grade 2 syncope and in 
another patient the dose of lenalidomide was compromised such that they received < 80% 
of the planned doses. Subsequent patients were treated at one dose level below 
(2.97 mg/m2) where one of 6 patients experienced a DLT (Grade 3 rash). The MTD of 
weekly MLN9708 in combination with Rd was established at 2.97mg/m2. However with 
this dose, 3 of 6 patients experienced Grade 2 and 3 rash and had to discontinue 
lenalidomide. Therefore, the recommended dose was determined to be 2.23 mg/m2 plus 
Rd in the phase 2 portion of the combination trial and phase 3 Rd combination trial.
To date, all 15 response-evaluable patients have achieved PR to therapy including 
4 CRs, 4 VGPRs, and 7 PRs; 14 out of 15 patients achieved PR after Cycle 1, and all 15

1.4.4
Nonclinical Pharmacology Studies
Pharmacokinetics of MLN2238 after IV weekly or twice-weekly MLN9708 dosing is 
multi-exponential with the rapid initial phase largely over by 4 hours followed by much 
slower disposition phases. The plasma MLN2238 concentration decreases by almost 
90% in the initial phase of 4 hours. The mean t1/2 after multiple IV dosing of MLN9708 
ranges from 4 to 8 days. Plasma MLN2238 exposures appear to increase proportionally 
with increasing dose over the MLN9708 IV dose range of 0.5 to 2.34 mg/m2. Oral 
MLN9708 is bioavailable and MLN2238 is rapidly absorbed with a Tmax of 0.5 to 8 hours. 
The mean terminal half-life after multiple dosing of oral MLN9708 ranges from 4 to 7 
days. MLN2238 exposures appear to increase proportionally with increasing dose over 
the oral MLN9708 dose range of 0.8 to 2.23 mg/m2. Blood 20S proteasome inhibition is 
dose dependent and immediate confirming target inhibition by MLN9708. Maximal 20S 
inhibition is approximately 60% to 62% for 1.76 mg/m2 twice-weekly IV dose and 60% 
to 72% for 2.23 mg/m2 twice-weekly oral dose. 
1.5
Known and Anticipated Risks and Benefits of MLN9708
1.5.1
Known and Anticipated Risks
Hematological Toxicities
Reversible thrombocytopenia, neutropenia, and anemia have been reported to date 
primarily at the higher doses tested. In addition to monitoring for recovery of blood 
counts, anemia, neutropenia, and thrombocytopenia induced by administration of 
MLN9708 should be managed in a similar manner to that used for myelosuppression 
resulting from standard cytotoxic chemotherapeutic agents. Administration of MLN9708 
should be modified as noted in each specific protocol with reinitiation of therapy at a 
reduced level from where thrombocytopenia, neutropenia, or anemia was noted has been 
instituted in the clinical studies.

Protocol Number: TB-MC010034
Date: 22 November 2016
Page 28 of 102
CONFIDENTIAL
Gastrointestinal Toxicities
Reversible diarrhea, nausea, vomiting, anorexia, constipation, and abdominal pain have 
been reported. Patients should be monitored for gastrointestinal toxicity and should be 
given appropriate supportive care that includes fluids for volume depletion and 
antibiotics for any associated infection. Other supportive measures such as loperamide or 
other antidiarrheal agents may be considered for diarrhea only if it is established that 
there is no active infection or anti-emetics including 5-HT3 antagonists are recommended.
Peripheral Neuropathy
Mild and reversible peripheral neuropathy has been reported. Therefore, patients on 
MLN9708 should be monitored for symptoms of neuropathy, such as a burning sensation, 
hyperesthesia, hypoesthesia, paresthesia, discomfort, neuropathic pain, or weakness. In 
cases of new or worsening sensory peripheral neuropathy, with or without pain, 
administration of MLN9708 should be modified as noted in each specific protocol.
Reinitiation of therapy at a reduced level from where symptoms were noted may be 
considered.
Lymphopenia
Reversible lymphopenia has been reported primarily at the higher doses tested.
Infrequent incidences of herpes zoster have been reported.
If lymphopenia is noted, patients may be at an increased risk of infection. In particular, 
lymphopenia can be associated with reactivation of herpes zoster and herpes simplex 
viruses. Initiation of antiviral therapy should be considered if infection occurs and 
prophylaxis therapy should then be initiated following the course of therapy for the 
infection and through the following courses of treatment with MLN9708.
Acute Phase Response
Acute phase response, characterized by increases in total WBC, neutrophils, monocytes, 
and fibrinogen, was observed in nonclinical studies. These can be monitored in the clinic 
by clinical chemistry and vital sign evaluations. Therefore, patients should be observed 
for fever and metabolic changes.

Fever
Cases of fever without neutropenia have been reported in the clinical studies; however, 
the relationship of onset of fever to MLN9708 is not yet completely established in 
humans. Patients may receive supportive care agents in response to fever that are 
associated with MLN9708.
Tumor Lysis Syndrome
Because MLN9708 is a cytotoxic agent and can rapidly kill malignant cells, patients with 
a high tumor burden prior to treatment should be monitored for the complications of 
tumor lysis syndrome with appropriate laboratory studies and supportive care.
Elevated Creatinine
Modest transient increases in creatinine and reversible renal failure have been reported.
In some situations this has been severe, requiring temporary dialysis. Appropriate 
supportive care that includes IV fluids to prevent volume depletion according to standard 
medical practice is recommended. Non-steroidal anti-inflammatory drugs are not 
recommended given they may in and of themselves have an association to renal 
dysfunction.
Erythematous Rash With or Without Pruritis
Rash with or without pruritus has been reported with MLN9708 primarily at the higher 
doses tested. The rash has been transient and has resolved with standard symptomatic 
measures such as oral, topical, or IV anti-histamines or corticosteroids.
Cough, Dyspnea, Peripheral Edema, Pneumonia/Pneumonitis, and Headache
Cases of cough, dyspnea, peripheral edema, pneumonia/pneumonitis, and headache have 
been reported in the clinical studies; however, the relationship of onset to MLN9708 is 
not yet completely established in humans. Standard supportive care and additional 
monitoring should be performed as clinically indicated.
Fatigue
Cases of profound fatigue have been reported in the clinical trials. Standard supportive 
care are recommended.

MLN9708 Investigator’s Brochure.
MLN9708, like Velcade®, is a modified dipeptidyl boronic acid derived from leucine and 
phenylalanine. MLN9708 is in the early stages of investigation in humans; therefore, its 
safety profile in humans is not yet fully known. For more detailed information regarding 
the risks associated with Velcade®, refer to the Velcade® 3 mg (bortezomib) for Injection 
Package Insert. 
1.5.2
Anticipated benefits
MLN9708 is a 20S proteasome inhibitor that has a mechanism of action similar to that of 
bortezomib, the clinical efficacy of which has been verified both in Japan and overseas.
MLN9708 demonstrates antitumor activity superior to that of bortezomib in some tumor 
models, and has exhibited antitumor activity even in bortezomib-resistant models. It is 
therefore hoped that MLN9708 will be effective in previously treated patients. In 
overseas clinical studies of MLN9708, patients have achieved partial response on 
MLN9708 monotherapy. In addition, since patients have achieved complete response
(CR), very good partial response (VGPR), and partial response (PR) in clinical studies of 
MLN9708 with Rd in patients with newly diagnosed multiple myeloma, MLN9708 is 
expected to exhibit antitumor activity in patients with newly diagnosed multiple myeloma 
as well. Furthermore, although most existing therapeutic medications for multiple 
myeloma are injectable formulations, oral formulation of MLN9708 may improve patient 
convenience.
1.6
Concomitant medications
In Japan, lenalidomide (
5 mg) has been approved for the treatment 
of relapsed or refractory multiple myeloma, and dexamethasone 
4 mg) has been approved for the treatment of multiple myeloma. The Rd combination 
therapy is one treatment option for relapsed or refractory multiple myeloma.

1.6.1
Lenalidomide
Lenalidomide is an immunomodulator that was discovered by 
in the US. It is a 
derivative of thalidomide, which is known to be teratogenic in man. Lenalidomide is 
known to manifest its antitumor activity through, for example, a cytokine production 
modulating action and an angiogenic tumor cell proliferation inhibiting action. Since the 
results of toxicity studies suggest that lenalidomide might be teratogenic, the 
lenalidomide proper management procedures (
) for preventing fetuses from 
being exposed to lenalidomide should be observed.
In this study, subjects will be registered in accordance with the lenalidomide proper 
management procedures when supplying lenalidomide to subjects receiving MLN9708 
plus Rd. The registration system for this study is described in “5.2
Registration”
1.6.2
Dexamethasone
Dexamethasone is a corticosteroid that, in addition to exhibiting anti-inflammatory and 
anti-allergy effects, also possesses various pharmacological effects, including inhibition 
of immune response and the metabolism of, for example, fats and sugars.
Dexamethasone also acts to inhibit the proliferation of multiple myeloma cells by 
inducing apoptosis, and it is known that dexamethasone can increase the effects of 
immunomodulators or chemotherapy agents that kill myeloma cells.
1.7
Study plan rationale
1.7.1
Rationale for starting to plan this study
As described in “1.1 Multiple myeloma,” the current treatments for relapsed or refractory 
multiple myeloma are all unsatisfactory. All are only effective in the short term, and 
ultimately result in treatment non-responsiveness. New, superior medications are 
therefore needed. In addition, most existing therapies are based on injectable 
formulations that require hospital visit and are therefore relatively inconvenient for
patients. MLN9708 is a 20S proteasome inhibitor that possesses a mechanism of action 
similar to that of bortezomib, an existing therapeutic medication for multiple myeloma,

and that can be taken orally. In nonclinical studies, MLN9708 exhibited antitumor 
activity superior to that of bortezomib in some tumor models, and exhibited antitumor 
activity in bortezomib resistant models as well, and it is therefore hoped that MLN9708 
will be effective in patients who have not responded to previous treatments. MLN9708 
was well-tolerated in an overseas phase 1 study in patients with relapsed or refractory 
multiple myeloma. Responders, including complete responders, were found, and the 
results of this study therefore suggest that MLN9708 will be useful. Based on the results 
that have been obtained in overseas clinical studies, including this phase 1 study, a global 
phase 3 study of the concomitant use of MLN9708 with Rd in relapsed or refractory 
multiple myeloma (Study C16010) has been planned, and Japan is expected to participate 
in this study as well. Therefore, a phase 1 study has been planned as the first clinical 
study of MLN9708 in Japan to confirm the tolerability and safety of MLN9708 alone and 
MLN9708 in combination with Rd in relapsed or refractory multiple myeloma.
1.7.2
Rationale for using a fixed dose
The results of a population pharmacokinetic analysis in 137 subjects who received 
MLN9708 in overseas studies suggest that neither body surface area nor body weight 
appreciably affect MLN9708 clearance or distribution volume. It was concluded that 
body surface area does not affect the Cmax or AUC, so changing to a fixed dose would be 
appropriate. In addition, since it has been decided that fixed doses will be used in future 
overseas clinical studies, we concluded that it would be appropriate to use a fixed dose in 
this Japanese phase 1 study as well. When converting the dose from a body surface area 
dose to a fixed dose, we used 1.86 m2, which was the mean body surface area of the 
subjects who participated in overseas clinical studies of bortezomib in multiple myeloma 
that were conducted by MPI. Converting 2.97 mg/m2, which was the MTD both in 
MLN9708 monotherapy and in the combined use of MLN9708 with Rd, was converted 
into a fixed dose, yielded a fixed dose of 5.5 mg, and converting 2.23 mg/m2, which is the 
recommended dose of MLN9708 when used in combination with Rd, yielded a fixed 
dose of 4.0 mg.

1.7.3
Rationale for including an MLN9708 + Rd cohort
Since this study will be the first clinical study of MLN9708 in Japan, we decided to first 
investigate the tolerability, safety and pharmacokinetics of MLN9708 in monotherapy. 
However, in the treatment of relapsed or refractory multiple myeloma, proteasome 
inhibitors, immunomodulators and steroid combination therapies are commonly used. 
The combined use of bortezomib, lenalidomide and low-dose dexamethasone (VRd)
therapy in multiple myeloma has been confirmed to be safe and effective (Anderson et al, 
2010; Kumar et al, 2010; Richardson et al, 2010a; Richardson et al, 2010b). MLN9708, a 
new proteasome inhibitor, is expected to possess pharmacological efficacy and safety 
superior to that of bortezomib. In study C16005, a study of the combined use of 
MLN9708 with Rd, not only did 15 of 15 subjects achieve PR or better response, but 
good safety results were obtained in all subjects as well. Given this result, a global phase 
3 study of the combined use of MLN9708 with Rd (study C16010) is currently being 
planned. Consequently, in this study, in addition to investigating MLN9708 monotherapy, 
we decided to also investigate MLN9708 when used in combination with Rd. For the 
dosages of Rd, we used the dosages used in overseas clinical studies in which the efficacy 
and safety of VRd therapy were confirmed. Comparison of the efficacy and safety of 
dexamethasone in 445 newly diagnosed multiple melanoma patients overseas between a 
group of 223 patients who received high-dose dexamethasone (40 mg/day on Days 1-4, 
9-12, and 17-20) and a group of 222 patients who received low-dose dexamethasone 
(40 mg/day on Days 1, 8, 15, and 22) revealed that low-dose dexamethasone afforded a 
level of efficacy similar to that obtained with high-dose dexamethasone (Rajkumar et al, 
2010). Weekly low-dose dexamethasone was therefore selected.
1.7.4
Rationale for the initial doses and cohorts
In study C16004, Grade 3 adverse events were reported in 2 of 6 subjects at the MTD of 
2.97 mg/m2 (equivalent to 5.5 mg), but Grade 3 or higher adverse events were not 
reported at the next lowest dose of 2.23 mg/m2 (equivalent to 4.0 mg). Therefore, in this 
study, we decided to use 4.0 mg at the initial dose (cohort 1). For the MLN9708 + Rd 
cohort (cohort 2), we selected a dose of 4.0 mg + Rd, which was the recommended dose 
in the MLN9708 + Rd phase 3 study and the phase 2 part of study C16005, and was the 
next dose level below the MTD of 2.97 mg/m2 (equivalent to 5.5 mg) in study C16005.

Furthermore, we have also established a monotherapy cohort that will receive 5.5 mg 
(cohort 3) and a MLN9708 + Rd cohort that will receive 5.5 mg + Rd (cohort 4) in order 
to confirm the tolerability in Japanese at the dose equivalent to the MTD overseas once 
the tolerability of 4.0 mg and 4.0 mg + Rd have been confirmed.
1.7.5
Rationale for once-weekly dosing
Based on the nonclinical and clinical study results, we selected a 28-day MLN9708 
dosing cycle with weekly oral dosing on Days 1, 8, and 15 and no dose given on Day 22. 
In a mouse model, peak antitumor activity was obtained with weekly dosing, and the 
results of multiple-dose toxicity studies also support the case for weekly dosing. 
MLN9708 weekly dosing was confirmed to be tolerable in study C16004 in relapsed or 
refractory multiple myeloma.
Since the global phase 3 study that is currently being planned (study C16010) will also 
employ a similar dosing method, we have decided to confirm the tolerability of such a 
dosing method in this study.

EXPERIMENTAL PLAN 
3.1
Study Design
This is a phase 1, multicenter, single-arm, open-label, dose-escalation study to evaluate 
the tolerability, safety, and pharmacokinetics of MLN9708 administered alone or in 
combination with Rd in patients with relapsed and/or refractory multiple myeloma. This 
study consists of the following 4 cohorts.
●
Cohort 1: MLN9708 4.0 mg
●
Cohort 2: MLN9708 4.0 mg + Rd
●
Cohort 3: MLN9708 5.5 mg
●
Cohort 4: MLN9708 5.5 mg + Rd
Three subjects will be enrolled sequentially from cohorts 1 (MLN9708 4.0 mg alone) to 4. 
If a DLT occurs in one subject during DLT-assessment period, 3 additional subjects will 
be enrolled in the applicable cohort to evaluate the tolerability in a total of 6 subjects. If 
DLT occurs in 2 of the 3 subjects, the given dosage is considered intolerable. If DLT 
occurs in 2 of the 6 subjects, the sponsor will determine the tolerability to the given 
dosage after discussing with the Efficacy and Safety Evaluation Committee (ESEC).  
The sponsor will evaluate the tolerability of MLN9708 on the basis of the safety data 
including DLT incidences during the DLT-assessment period.  The sponsor will decide 
whether the next cohort will be studied and the dose of the next cohort in consultation 
with the ESEC, if necessary. If the current cohort is considered tolerable, the next cohort 
will be in the order of cohorts 2 (MLN9708 4.0 mg + Rd), 3 (MLN9708 5.5 mg alone), 
and 4 (MLN9708 5.5 mg + Rd).  Even if a dosage is considered tolerable and transition to 
the next cohort is considered feasible, the next cohort may not be studied based on the 
results of the overseas clinical studies and the current study.
The additional written informed consent for extended treatment will be obtained before 
the first dose of MLN9708 in Cycle 2 from the subjects who meet the criteria in “6.4
Criteria for Beginning the Next Cycle of Treatment” and have no safety concern. 
Subjects who do not give the consent will undergo end of study (EOS) visit on 29 days 
after the last dose of MLN9708 in Cycle 1. The subjects giving the consent can continue

the study treatment up to 12 cycles unless they meet the criteria in “8.1 Removal of 
Subjects” including evidence of progressive disease (PD) and intolerable toxicity. 
Subjects may remain on treatment after the 12 cycles if the investigator considers it 
beneficial for the subjects.
All subjects should undergo EOS visit on 29 days after the last dose of MLN9708.
The overall study design is described in “Study Design and Treatment Schema” (page 8).
3.2
Study Centers
The study is planned at 5 study centers.
3.3
Number of Subjects
Approximately 12 to 24 subjects (3 to 6 subjects in each cohort) will be enrolled in the 
study.
If any significant protocol deviation that affects DLT assessment is observed or a subject 
could not complete the protocol-specified MLN9708 treatment during the DLT-
assessment period for reasons other than DLTs, the subject will be excluded from the 
DLT assessment, and additional subject(s) may be enrolled. Moreover, if there seems to 
be needs for additional data for safety or pharmacokinetics evaluation, the sponsor may 
decide to enroll additional subjects. See “10.2 Sample Size Considerations for the 
sample size justification.
3.4
Estimated Study Duration
The study will be conducted between March 2012 and March 2019.
3.4.1
Study Duration for Participants
Study duration for patients will last for up to approximately 14 months, including 
maximum of 4 weeks screening period, maximum 12 cycles of treatment period 
(approximately 12 months), and 4 weeks follow-up after the last dose. Subjects may 
remain on treatment after the 12 cycles if the investigator and the sponsor determine that 
the subjects would derive benefit from continued therapy beyond 12 months.

SUBJECT ENROLLMENT
The investigators must obtain written informed consent from all subjects before any study 
specific procedures are performed.
All subjects who enter into the screening period for the study (defined as the point at 
which the subject signs the informed consent) will receive a unique, 8-digits subject 
identification number (e.g. 34XXXYYY). The first 2 digits (i.e. 34) represent the 
protocol number, next 3 digits (XXX) represent the study center number, and the last 3 
digits (YYY) represent the subject number which is assigned in each study center. 
This number will be used to identify the subject throughout the study and must be used 
on all study documentation related to that subject. The subject identification number 
must remain the same throughout the entire clinical study; it must not be changed at the 
time of re-screening or re-enrollment. The number is assigned in sequential order of the 
subject’s consent at the site, in principle (e.g. 001, 002, 003).
Subjects must be registered within 28 days of the consent.
Subjects not meeting the eligibility criteria during the screening period cannot be enrolled.
However, subjects can be re-screened with the investigator’s discretion as long as they 
are not registered as a screen failure. When subjects are re-screened, the investigators 
must obtain additional written informed consent before the re-screening to reconfirm the 
subject’s consent for study participation. A subject cannot be re-screened more than once, 
and will be defined as a screen failure if subject is not qualified to undergo re-screening 
or is determined as a screen failure after the re-screening.
A subject will be defined as a screen failure, if the subject signs the informed consent but 
fails to enroll into the study. The investigators must document all screen failures and the 
reasons for the failure on the electronic case report form (eCRF).
For addition or replacement of subjects, refer to “8.2 Replacement of Subjects”.

Enrollment Procedures
After the completion of subject screening for each subject, the investigator enrolls the 
subject according to the following procedures:
The investigator ensures that a subject meets all the eligibility criteria and faxes a 
“subject registration sheet” to the Registration Center after confirming the necessary 
information is completed. The “subject registration sheet” may be the source data of the 
investigator’s judgment for the each eligibility criteria.
The Registration Center confirms that a subject meets the all inclusion criteria and does 
not meet any of the exclusion criteria, and then the Registration Center identifies the 
subject as an enrolled subject and faxes a “registration confirmation sheet” to the 
investigator. If a subject is considered ineligible by the Registration Center, the center 
will not identify the subject as an enrolled subject. A “registration confirmation sheet”
describing the “reason for ineligibility” will be faxed to the investigator. 
The investigator must retain a “subject registration sheet”, a “registration confirmation 
sheet”, and the “reason for ineligibility” as the source documents appropriately in the 
study centers.
The Registration Center will report above subject registration progress promptly to the 
sponsor.

A missed dose of lenalidomide can be taken as soon as the patient remembers provided 
that it is within 12 hours from the regular dosing schedule. A double dose should not be 
taken to make up for a missed dose. If enough time has elapsed that the missed dose is 
not taken within the same day, the missed dose should be skipped. If the patient vomits 
after taking a dose, the patient should not repeat the dose but should resume dosing at the 
time of the next schedule.
6.3.3
Dexamethasone Administration (Rd Concomitant Cohort Only)
Dexamethasone will be administered as a single, oral dose of 40 mg/day weekly on Days 
1, 8, 15, and 22 of a 28-day cycle.

6.5.2
MLN9708 in combination with Rd
6.5.2.1
Criteria for Dose Modification
Dose modifications of MLN9708 are not permitted in Cycle 1. Dose modifications of Rd
should be avoided as much as possible. If a subject experiences an adverse event(s) 
considered strongly related to lenalidomide or dexamethasone and the investigator 
considers it difficult to continue the treatment with Rd, the investigator and the sponsor 
will discuss the alternative dose modification.
If dose modification is required in Cycle 2 or subsequent cycles, MLN9708, lenalidomide, 
or dexamethasone dose will be modified levels according to Table 6-5. If multiple 
toxicities are noted, the dose should be modified or delayed according to the most severe 
toxicity guidelines (Table 6-6 through Table 6-11). Once a dose is reduced, no re-
escalation will be permitted.

Cohort Transition and Early Stopping Guidelines
6.6.1
Cohort Transition
Three subjects will be initially enrolled into each dose level in order starting with cohort 
1. The sponsor will evaluate the tolerability of MLN9708 dosage in each cohort on the 
basis of the DLT incidences in consultation with the ESEC, if necessary.
Even if a dosage is considered tolerable and transition to the next cohort is considered 
feasible, the next cohort may not be studied based on the results of the overseas clinical 
studies and the current study.

Product: MLN9708
Protocol Number: TB-MC010034
Date: 22 November 2016
Page 59 of 102
CONFIDENTIAL
1. Cohort Transition From Cohort 1 to Cohort 2
If no DLT occurs during the DLT assessment period for cohort 1 (the initial dose through 
before Cycle 2), the dosage will be considered tolerable. If a DLT occurs in one subject
during the DLT assessment period, 3 additional subjects will be enrolled into a given dose 
level to evaluate tolerability in a total of 6 subjects. If DLTs occur in no more than 1 of 
the 6 subjects, then this dosage will be considered tolerable. If DLTs occur in 2 of 3 
subjects, then this dosage will be considered intolerable. If DLTs occur in 2 of 6 subjects, 
the sponsor will determine the tolerability of this dosage in consultation with the ESEC.
Even if a dosage is considered tolerable, the appropriateness of transition to cohort 2 will 
be determined by the sponsor in consultation with the ESEC as necessary.
2. Cohort Transition From Cohort 2 to Cohort 3
If no DLT occurs during the DLT assessment period for cohort 2, the dosage will be 
tolerable. If a DLT occurs in one subject during the DLT assessment period, 3 additional
subjects will be enrolled into a given dose level to evaluate tolerability in a total of 6 
subjects. If DLTs occur in no more than 1 of the 6 subjects, then this dosage will be 
considered tolerable. If DLTs occur in 2 of 3 subjects, then this dosage will be considered 
intolerable. If DLTs occur in 2 of 6 subjects, then the sponsor will determine the 
tolerability of this dosage in consultation with the ESEC. Even if a dosage is considered 
tolerable, the appropriateness of transition to cohort 3 will be determined by the sponsor 
in consultation with the ESEC as necessary. If the cohort 2 dosage is found to be 
intolerable, the sponsor will determine the appropriateness of transition to cohort 3 based 
on the data obtained from cohort 1 and cohort 2 in consultation with the ESEC.
3. Cohort Transition From Cohort 3 to Cohort 4
If no DLTs occur during the DLT assessment period for cohort 3, the dosage will be
tolerable. If a DLT occurs in one subject during the DLT assessment period, 3 additional
subjects will be enrolled into a given dosage level to evaluate tolerability in a total of 6 
subjects. If DLTs occur in no more than 1 of the 6 subjects, then this dosage will be 
considered tolerable. If DLTs occur in 2 of 3 subjects, then this dosage will be considered 
intolerable. If DLTs occur in 2 of 6 subjects, then the sponsor will determine the 
tolerability of this dosage in consultation with the ESEC. Even if a dosage is considered

tolerable, the appropriateness of transition to cohort 4 will be determined by the sponsor 
based on the data obtained from cohort 2, in consultation with the ESEC as necessary.
6.6.2
Early Stopping Guidelines
Should the start of the next cycle need to be delayed for more than 3 weeks because of 
incomplete recovery from treatment-related toxicity (6.4.3 Criteria for Dose Delays), the 
patient undergoes the EOS exams, and treatment should be discontinued.
6.7
DLT
6.7.1
DLT Assessment Period
DLTs will be assessed from the first dose until Cycle 2 Day 1 of MLN9708 treatment.
6.7.2
DLT-Evaluable Subjects
DLT-evaluable subjects are defined as follows:
•
DLTs 1 during DLT-assessment period.
OR
•
Received 3 doses of MLN9708 specified for the applicable cohort and completed 
the DLT-assessment period.
Subjects whose treatment with MLN9708 was interrupted or reduced in Cycle 1 for 
reasons other than DLTs are not eligible for DLT assessment in principle.
6.7.3
Definitions of DLT
DLT will be defined as any of the following AEs that are considered possibly related to 
MLN9708. Toxicity will be accessed according to the CTCAE version 4.03.
1.
Grade 4 neutropenia (ANC < 500/mm3 ) lasting more than 7 consecutive days.
2.
Grade 3 or greater neutropenia (ANC < 1,000/mm3 ) with fever and/or infection, 
where fever is defined as axillary temperature ≥ 38.0ºC.
3.
Grade 4 thrombocytopenia (platelets < 25,000/mm3) lasting more than 7 consecutive 
days.
4.
Grade 3 or greater thrombocytopenia (< 50,000/mm3) with clinically significant 
bleeding, or which requires blood transfusion.

5.
A platelet count 10,000/mm3.
6.
Grade 2 peripheral neuropathy with pain or Grade 3 or greater peripheral neuropathy.
7.
Any other Grade 3 or greater nonhematologic toxicities with the following 
exceptions:
•
Grade 3 or greater arthralgia/myalgia.
•
Grade 3 or greater fatigue lasting less than 7 days.
•
Grade 3 nausea and/or emesis which can be controlled with anti-emetic therapies 
including anti-emetic prophylaxis. Anti-emetic prophylaxis is defined as an anti-
emetic regimen that employs a 5-HT3 antagonist given in standard doses and 
according to standard schedules. Dexamethasone should not be administered as 
an anti-emetic.
•
Diarrhea that is controlled with appropriate supportive care
8.
A delay of more than 14 days in the initiation of Cycle 2 treatment because of a lack 
of adequate recovery of MLN9708 related hematological or nonhematologic 
toxicities.
9.
Other Grade 2 or greater MLN9708 related nonhematologic toxicities that, in the 
opinion of the investigator, require permanent discontinuation of MLN9708.
10. Inability to give at least 80% of the planned lenalidomide doses (Rd combination 
cohort only) due to the adverse events related to MLN9708.
When a subject experiences any of the above DLTs, MLN9708 therapy should be 
interrupted within the same cycle after DLT. With agreement by the sponsor, 
investigators may consider restarting the MLN9708 therapy from next cycle for subjects 
continue to clinically benefit from the therapy. MLN9708 should be reinitiated in 
accordance with “6.4.3 Criteria for Dose Delays”.
The sponsor will consult with the ESEC for the final decision if determination of DLT or 
subjects’ eligibility for DLT-assessment is difficult.

Before any protocol-specified procedure, all subjects must sign and date the informed 
consent form.
The investigator will be expected to create and maintain a screening log for all potential 
study candidates that includes information about the potential candidate (sex, date of 
birth), date, and outcome of the screening process (e.g., enrollment into study, reason for 
ineligibility or refused to participate).
All existing test results (e.g., HIV, hepatitis B virus [HBV], HCV), diagnostic imaging 
results (e.g., X-ray, CT, MRI) and bone marrow test results, for example, obtained prior 
to the date of consent acquisition may be used as data at the time of screening, provided 
the subject's consent is obtained.
7.2
Examinations, observations, and evaluations
The investigator will conduct examinations, observations, and evaluations of the subject 
according to the following procedures from the informed consent until the end of 
treatment visit. The subject assessments/observations will all be performed by the same 
investigator, in principle.
7.2.1
Screening period
All of the following exams, observations, and evaluations will be performed within 28 
days before first dose, unless otherwise specified. Subjects meeting all of the eligibility 
criteria specified in "4 SUBJECT ELIGIBILITY" prior to subject enrollment will be

REMOVAL AND REPLACEMENT OF SUBJECTS
8.1
Removal of Subjects
Subjects have the right to withdraw fully or partially from the study at any time and for 
any reason.
Withdrawal of full consent for a study means that the subject does not wish to receive 
further study treatment and does not wish to or is unable to continue further study 
participation.  Any subject may withdraw full consent to participate in the study at any 
time during the study.  The investigator will discuss with the subject the most appropriate 
way to withdraw to ensure the subject’s health.  
Withdrawal of partial consent means that the subject does not wish to take investigational 
product any longer but is still willing to collaborate in providing further data by 
continuing on study (e.g. participate in all subsequent study visits or procedures).  
Subjects may withdraw partial consent to continue receiving investigational product at 
any time during the study.  These subjects should continue the schedule of study 
observations.  
Subjects who discontinue the investigational product by investigator’s discretion or 
reasons other than the subject’s withdrawal of consent also must continue the schedule of 
study observations.  
All the procedures should be completed for the subject who discontinued the study by 
any reasons except the withdrawal of full-consent, lost to follow-up or death.  If study 
observations cannot be performed due to unavoidable circumstances, such as the 
worsening of the subject’s condition, the reasons must be documented on the source 
documents and no further follow-up is necessary.  In this case, the missing of protocol-
specified tests or assessments between the day of the last dose of the investigational 
product and the 29th day after the last dose will not be considered as any protocol 
deviations.
Reasons for removal from investigational product or observation might include:

Replacement of Subjects
Subjects in this study who have not received study treatment may be replaced.
If any major protocol deviation that potentially affects DLT assessment for reasons other 
than safety concerns as DLT occurs during DLT assessment period, the subject will be 
excluded from the DLT assessment and additional subjects may be enrolled in this cohort.  
Additional patients may also be enrolled throughout the study if there seems to be a need 
for additional data for safety or pharmacokinetics evaluation.

SAFETY DATA COLLECTION, RECORDING, AND REPORTING
9.1
Definitions
9.1.1
Adverse Events
An adverse event is any untoward medical occurrence or unintended signs, symptoms, or 
disease (including abnormal laboratory findings) appears in a subject which does not 
necessarily have a causal relationship to the study treatment.  Adverse events may include 
the onset of new illness and worsening of pre-existing conditions. 
The worsening of pre-existing medical condition indicates that the condition becomes
worse in severity, frequency, or duration, or has an association with a significantly worse 
outcome.  A pre-existing condition that has not worsened during the study, and a non-
emergent medical procedure such as elective cosmetic surgery is not considered an 
adverse event.
Disease progression itself is not considered as an adverse event; however, signs and 
symptoms of disease progression will be recorded as adverse events.  If a new primary 
malignancy appears, it will be regarded as an adverse event.
The investigator is responsible for reviewing laboratory test results and determining 
whether an abnormal value in an individual study subject represents a change from values 
before the study.  In general, abnormal laboratory findings without clinical significance 
(based on the investigator's judgment) should not be recorded as adverse events; however, 
laboratory value changes requiring therapy or adjustment in prior therapy are regarded as 
adverse events.
9.1.2
Serious Adverse Events
A serious adverse event is defined as an adverse event that
●
is fatal
●
is life threatening (places the subject at immediate risk of death)
●
requires in-patient hospitalization or prolongation of existing hospitalization
●
results in persistent or significant disability/incapacity

Product: MLN9708
Protocol Number: TB-MC010034
Date: 22 November 2016

CONFIDENTIAL
●
is a congenital anomaly/birth defect
●
is other significant medical hazard
A hospitalization meeting the regulatory definition for “serious” is any inpatient hospital 
admission that includes a minimum of an overnight stay in a health care facility.  Any 
adverse event that does not meet the definitions of serious (e.g., emergency room visit, 
outpatient surgery, or requires urgent investigation) may be considered by the investigator 
to meet the “other significant medical hazard” criterion for classification as a serious 
adverse event.
9.2
All Adverse Events Reporting Procedures
The investigator is responsible for ensuring that all adverse events (as defined in "Section 
9.1 Definitions" and as further specified below) observed by the investigator or reported 
by subjects are collected and recorded in the subjects’ medical records, in the eCRF, and, 
for serious adverse events, on the serious adverse event report form.  These adverse 
events will include the following:
●
All non-serious adverse events (as defined in "Section 9.1.1 Adverse Events") that 
occur after initiation of investigational product to an end-of-study.  
●
All serious adverse events (as defined in "Section 9.1.2 Serious Adverse Events") that 
occur after the subject has signed the informed consent form to an 
end-of-study, and treatment-related serious adverse events that occur after the end-of-
study.
The following adverse event attributes must be assigned by the investigator.  The sponsor 
may ask the investigator to provide follow-up information, extracts from medical record, 
or eCRFs.
●
Adverse event diagnosis or syndrome(s) ( signs or symptoms if not known)
●
Event description (with detail appropriate to the event)

CONFIDENTIAL
If applicable, the relationship of the adverse event to the study treatment will be assessed 
by Yes or No.
CTCAE version 4.03 will be used for grading adverse events.  
Adverse events requiring follow-up as determined by the investigator will be followed 
until resolved or considered stable.  If the investigator judged that further follow-up is not 
necessary or follow-up is not possible before the adverse event is resolved or stable, 
follow-up may be terminated.
It will be left to the investigator’s clinical judgment to determine whether an adverse 
event is related and of sufficient severity to require the subject’s removal from treatment 
or from the study.  A subject may also voluntarily withdraw from treatment due to what 
he or she perceives as an intolerable adverse event.  If either of these situations arises, the 
subject should be strongly encouraged to undergo an end-of-study assessment and be 
under medical supervision until symptoms cease or the condition becomes stable.
9.3
Serious Adverse Event Reporting Procedures
All serious adverse events that occur after the subject has signed the informed consent 
form must be reported to the sponsor within 24 hours of discovery or notification of the 
event.  Initial serious adverse event information and all amendments or additions must be 
recorded on a serious adverse event report form and submitted to the sponsor.  Copies of 
relevant medical records should be submitted to the sponsor as soon as they become 
available; autopsy reports should be provided for deaths if available.  
Serious adverse events occurring after the end of the study and thought to be possibly 
related to the study treatment will be collected and reported within 24 hours of discovery 
or notification of the event.  
If a subject is permanently withdrawn from the treatment or from the study because of a 
serious adverse event, this information must be included in the initial or follow-up serious 
adverse event report form as well as the eCRF.

As a principle, initial information of a serious adverse event must be recorded on a 
predefined serious adverse event report form [initial report] and faxed by the investigator 
to the sponsor.  The original initial report must be submitted to the study monitor.  
The principal investigator should submit detailed information without delay after 
notification of initial information.  As a principle, detailed report(s) must be recorded on a 
predefined serious adverse event report form and faxed to the sponsor.  The original 
detailed report(s) must be submitted to the study monitor.  If amendment is needed, the 
amendment should be reported according to the same procedure.
An operator of the Emergency Center for Safety Information is also available for contact 
24 hours 365 days. 
Emergency center for safety information (available 24 hours 365 days)
The principal investigator should inform the head of the medical institution of all serious 
adverse events occurring at the center in accordance with procedures required at the 
center and notify the sponsor according to this protocol.  
Determination of expectedness will be based on the contents in the latest investigator’s 
brochure (including information on the adverse events that have already been reported to 
the medical institution).

and based on the Helsinki Declaration, the protection of the human rights of subjects will 
be given first priority. 
Quality control of data will be conducted following the sponsor’s standard operating 
procedures related to the conduct of clinical studies.  The sponsor’s audit, which is 
independent of and separate from routine monitoring or quality control functions, will 
ascertain, for quality assurance of a clinical trial, whether the clinical trial is conducted in 
compliance with the J-GCP, the protocol, and the operating procedures.
11.2
Informed Consent
An initial generic informed consent template form is provided for the principal 
investigator to prepare the informed consent document to be used at the site.  Updates to 
the template will be communicated by letter from the sponsor to the principal investigator.  
The written informed consent document should be prepared in Japanese.
Before a subject’s participation in the clinical study, the investigator is responsible for 
obtaining written informed consent from the subject after fully informing the aims, 
methods, anticipated benefits, and potential hazards of the study and before any protocol-
specific screening procedures or any investigational products are administered.
The acquisition of informed consent should be documented in the subject’s medical 
records, and the informed consent form should be signed and personally dated by the 
subject, by the investigator and by the person who conducted the informed consent 
discussion.  The original signed informed consent form should be retained in accordance 
with institutional policy, and a copy of the signed consent form should be provided to the 
subject or legally acceptable representative.

A copy of the protocol, proposed informed consent form, other written subject 
information, and any proposed advertising material must be submitted to the institutional 
review board (IRB) for written approval.  A copy of the written approval of the protocol 
and informed consent document must be received by the sponsor before recruitment of 
subjects into the study and shipment of investigational product.
The sponsor must submit and, where necessary, obtain approval from the IRB for 
protocol amendments and changes to the informed consent document if applicable.  The 
investigator should notify the head of the medical institution of deviations from the 
protocol or serious adverse events occurring at the site and other adverse event reports 
received from the sponsor, in accordance with local procedures.
The investigator will be responsible for obtaining annual approval/renewal of the head of 
the medical institution throughout the duration of the study.  Copies of the investigator’s 
reports and the head of the medical institution’s continuance of approval must be sent to 
the sponsor.  
11.4
Subject Confidentiality
The investigator must ensure that the subject’s confidentiality is maintained:  
●
On the eCRFs or other documents submitted to the sponsor, subjects should be 
identified by the subject identification number only.  
●
On the serious adverse event forms submitted to the sponsor, subjects should be 
identified by a subject study number only.  
●
Documents that are not for submission to the sponsor (e.g., signed informed consent 
forms) should be kept in strict confidence by the investigator.
In compliance with J-GCP, it is required that the investigator and institution permit 
authorized representatives (study monitors or auditors) of the company, of the regulatory

verification of study-related procedures and data.  Direct access includes examining, 
analyzing, verifying, and reproducing any records and reports that are important to the 
evaluation of the study.  The investigator is obligated to inform and obtain the consent of 
the subject to permit named representatives to have access to his/her study-related records 
without violating the confidentiality of the subject.
11.5
Dissemination of New Information
When information important to the proper conduct of the clinical study becomes 
available such as on diseases, impairment, and deaths suspected to be due to the effect of 
the investigational product, onset of infections suspected to be due to the use of the 
investigational product, and other information related to the investigational product 
quality, efficacy, and safety, the sponsor will promptly notify the investigators, the heads 
of medical institution, medical experts, and the ESEC in writing and take necessary 
measures. Of note, the sponsor will finish the report to the ESEC at the end of October 
2016.
Once it is determined that the information provided by the sponsor may affect a subject’s
willingness to continue participation, the investigator should promptly provide the 
information to the subjects, document, and ensure his/her willingness to continue 
participation.  When the sponsor requires the investigator to ensure the subject’s 
willingness to continue participation, or the investigator obtains information that may 
affect a subject’s willingness to continue participation as well, the investigator will ensure 
the subject’s willingness to continue participation.

Overview of Study 
Design 
 
The sponsor will evaluate the tolerability of MLN9708 
dosage on the basis of the safety data including DLT 
incidences during the DLT-assessment period.  The 
sponsor will decide whether the next cohort will be 
studied and the dose of the next cohort in consultation 
with the ESEC, if necessary.  If the current cohort is 
considered tolerable, the next cohort will be in the order 
of cohorts 2 (MLN9708 4.0 mg plus Rd), 3 (MLN9708 
5.5 mg alone), and 4 (MLN9708 5.5 mg plus Rd).

Schedule of 
Assessments 
Radiographic assessment (systemic)q 
q If bone X-rays is performed within 8 weeks before the 
first dose, the X-ray results may be used as screening 
data.  For any patient with documented osteolytic 
disease at screening, repeat the assessment again at EOS.  
If there are symptoms or signs that suggest increased or 
new bone lesions during the study treatment, repeat the 
procedure as necessary at any point.  Repeat scans 
should use the same imaging modality throughout the 
study.
