Sarcoma Treated with Olaratumab Monotherapy Followed by

5. Introduction
5.1.
Rationale and Justification for the Study
Soft tissue sarcoma (STS) is a heterogeneous group of tumors that arise mainly from embryonic 
mesoderm, with some neuroectodermal contribution and differentiation to non-epithelial 
extraskeletal tissue including muscle, fat, and fibrous tissue (D’Angelo et al. 2014).  There are 
approximately 50 tumor subtypes of STS (Sharma et al. 2013) and they can be located anywhere 
in the body.  Soft tissue sarcoma is rare, comprising approximately 1% of adult cancers. The
annual incidence of STS in the United Kingdom and United States is 3300 and 10,000, 
respectively (Jemal et al. 2009; NCIN [WWW]).  Soft tissue sarcoma is best treated by 
multidisciplinary teams specialized in the management of these tumors (Linch et al. 2014). 
When the disease is localized, it is usually treated with curative intent using surgical resection 
with or without radiotherapy and/or chemotherapy.  Unfortunately, STS recurs frequently as 
locally inoperable or metastatic disease, at which time systemic therapy plays a prominent role in 
the multidisciplinary management of this tumor.  Single-agent doxorubicin is still considered the 
standard treatment option for many patients with metastatic STS (NCCN 2011; ESMO 2014; 
Schoffski et al. 2014) and has also been used in the pre-operative setting (NCCN 2016).  
Previously reported data supported the advancement of olaratumab (IMC-3G3, LY3012207) in 
later phase human trials, including Eli Lilly and Company (Lilly)’s Phase 1b/2 randomized Phase 
2 Study I5B-IE-JGDG (JGDG), which evaluated the efficacy and safety of doxorubicin with or 
without olaratumab in advanced STS.  Patients treated with olaratumab and doxorubicin in the 
Phase 2 portion of this study, compared to those treated with single-agent doxorubicin, achieved 
a higher median progression-free survival (PFS; 6.6 vs. 4.1 months, respectively [stratified 
hazard ratio (HR) = 0.672 (95% confidence interval [CI]:  0.442, 1.021); p = 0.0615]), median 
overall survival (mOS; 26.5 vs. 14.7 months, respectively [stratified HR = 0.463 (95% CI:  
0.301, 0.710); p = 0.0003]) and objective response rate (ORR; 18.2% vs. 11.9%, respectively; 
p = 0.3421), with an acceptable and monitorable safety profile. 
The efficacy of olaratumab in this STS patient population provides an important opportunity to 
more fully characterize the mechanism of action (MOA) of olaratumab.
Olaratumab is a recombinant human immunoglobulin G, subclass 1 (IgG1) antagonist of the 
platelet-derived growth factor receptor alpha (PDGFR, which has been demonstrated to play 
an important role in mesenchymal biology, and in modulating the tumor and stromal 
microenvironment.  Preliminary analysis of tumor specimens from Study JGDG indicated that 
tumor expression of PDGFRreceptor by immunohistochemistry (IHC) did not predict 
improvement in mOS. Possible explanations for this finding include the highly variable and 
often lengthy time periods between tumor sampling and study entry, the analysis of primary 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 17
LY3012207
versus metastatic lesions, and incomplete understanding of the level of PDGFRreceptor and 
ligand expression in tumor and stroma needed for efficacy.
For these reasons, this study will enroll patients with potentially resectable STS, to allow pre-
and post-olaratumab dosing tumor sampling of the same primary tumor lesion, while also 
providing the potential opportunity to examine a resected tumor specimen after combination 
treatment with olaratumab and doxorubicin. 
Platelet-derived growth factor receptor alpha activation leads to the activation of several well-
characterized downstream signaling cascades including the Ras/mitogen-activated protein kinase 
(MAPK) pathway, the phosphatidylinositol 3-kinase pathway, and the phospholipase C-ɣ 1 
pathway in sarcomas (Shah et al. 2010).  Increased expression of PDGFRα has been described in 
epithelial malignancies as part of the epithelial-mesenchymal transition (EMT) (Jechlinger et al. 
2006).  The EMT state is associated with increased invasiveness and metastasis (Thiery et al. 
2009).  Autocrine signaling via PDGFRα in association with Ras oncogenic mutation is 
positively correlated with metastasis in a murine breast cancer line (Jechlinger et al. 2006).  Non-
canonical activation of PDGFRαpromotes bone metastasis of prostate cancer cells, and 
inhibition of PDGFRα in prostate cancer suppresses tumor angiogenesis and growth of skeletal 
metastases (Doloff et al. 2007; Russell et al. 2009, 2010; Park et al. 2011). Given this growing 
body of literature, the ability of olaratumab to disrupt sarcoma metastasis will be investigated in 
Study I5B-MC-JGDM (JGDM).
The predilection for sarcomas to spread hematogenously provide rationale for using a whole 
blood “liquid biopsy” approach for enumeration and characterization of circulating sarcoma 
tumor cells pre- and posttreatment with olaratumab to investigate the role of olaratumab in 
disrupting the metastatic potential of sarcomas.  Using serial pre- and posttreatment whole blood 
samples, the proposed study will investigate the effects of olaratumab (as monotherapy and in 
combination with doxorubicin) on circulating tumor cell (CTC) counts.  The whole blood 
samples may also be used for exploratory analyses and further molecular characterization.
The sponsor (Lilly), monitor, and investigators will perform this study in compliance with the 
protocol, good clinical practice (GCP) and International Conference on Harmonisation (ICH) 
guidelines, and applicable regulatory requirements.

5.3.
General Introduction to Olaratumab
Olaratumab is a recombinant human IgG1-type monoclonal antibody that binds to PDGFRα.  
This antibody possesses high affinity binding for PDGFRα and blocks platelet-derived growth 
factor (PDGF)-AA, -BB, and -CC from binding to the receptor.  In addition to blocking ligand-
induced cell mitogenesis and receptor autophosphorylation, olaratumab inhibits ligand-induced 
phosphorylation of the downstream signaling molecules Akt and MAPK (Loizos et al. 2005; 
Study Report IMC-3G3-01).
Platelet-derived growth factor/PDGFRα signaling has been implicated in the pathogenesis of 
multiple cancers, including sarcoma, prostate cancer, breast cancer, ovarian cancer, and others.  
In malignant disease, the PDGF/PDGFRα axis promotes tumor growth and proliferation through 
both autocrine and paracrine mechanisms.  Platelet-derived growth factor receptor alpha can be 
expressed in both the tumor and stromal microenvironment.  Furthermore, studies have shown 
that PDGF/PDGFRα signaling affects tumor vasculature through paracrine mediation of vascular 
endothelial growth factor production (Shah et al. 2010).

More information on the known and expected benefits, risks, and reasonably anticipated adverse 
events (AEs) of olaratumab may be found in the Investigator’s Brochure (IB).  Information on 
AEs expected to be related to the investigational product (IP) may be found in Section 7 
(Development Core Safety Information [DCSI]) of the IB.  Information on serious adverse 
events (SAEs) expected in the study population independent of drug exposure and that will be 
assessed by the sponsor in aggregate, periodically during the course of the study, may be found 
in Section 6 (Effects in Humans) of the IB.

can be found in the approved doxorubicin package insert.
5.4.
Rationale for Selection of Dose
The current olaratumab dose-selection strategy for this study is based on the integrated safety, 
efficacy, and PK data for olaratumab across previous Phase 1 and Phase 2 studies.  
In 2 Phase 1 dose-escalation trials (Studies I5B-IE-JGDC and I5B-IE-JGDF) and in the 2 Phase 
2 monotherapy studies (Studies I5B-IE-JGDE and I5B-IE-JGDH), single-agent olaratumab has 
consistently been well tolerated, with no dose-limiting toxicities observed up to a dose of 20 
mg/kg administered every 2 weeks and up to a dose of 15 mg/kg administered on Days 1 and 8 
of a 21-day cycle.  When used in combination with liposomal doxorubicin in Study I5B-IE-
JGDA (olaratumab dose of 20 mg/kg every 2 weeks), and with paclitaxel plus carboplatin in 
Study I5B-IE-JGDB (olaratumab dose of 15 mg/kg Days 1 and 8 every 3 weeks), a higher rate of 
toxicities such as neutropenia and infections was observed versus the comparator agents.  In 
Study JGDG, an increase in neutropenia and mucositis, but not in neutropenic sepsis or febrile 
neutropenia, was observed for olaratumab plus doxorubicin compared with single-agent 
doxorubicin.  Overall, these toxicities are consistent with the toxicity profile of the combination 
agents used, and are considered monitorable and acceptable for the patient populations studied.
Based on an exposure-response analysis of data from Study JGDG, an olaratumab loading dose 
of 20 mg/kg on Day 1 and Day 8 of Cycle 1 was incorporated into Study I5B-MC-JGDJ (JGDJ), 
an ongoing randomized Phase 3 trial of doxorubicin plus olaratumab versus doxorubicin plus 
placebo in patients with advanced or metastatic STS. The goal of this dosing refinement was to 
decrease the time patients achieved steady state concentrations of olaratumab.
Study JGDM will consist of an initial cycle of olaratumab monotherapy (Cycle 1) administered 
on Day 1 and Day 8 of a 21-day cycle using a dose of 20 mg/kg.  This dose is consistent with the 
loading dose used in Study JGDJ, and is anticipated to provide olaratumab concentrations 
optimal for testing olaratumab tumor and CTC biomarker effects during Cycle 1.  
Because the patient population for Study JGDM consists of patients who have potentially 
resectable STS, early tumor reduction is an important therapeutic goal.  Therefore, in Cycle 2, 
patients will receive additional 20 mg/kg doses of olaratumab on Day 1 and Day 8, in 
combination with 75 mg/m2 doxorubicin on Day 1 of a 21-day cycle (totaling 2 cycles of 
olaratumab at a 20 mg/kg dose: 1 as monotherapy and 1 in combination with doxorubicin).  This 
dosing schedule is intended to maximize the number of patients reaching potentially therapeutic 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 20
LY3012207
drug concentrations in the first 6 weeks, which is potentially important in this patient population. 
Pharmacokinetic model simulations indicate that this proposed dosing regimen may result in 
exposures slightly (approximately 15%) above previously studied steady-state serum levels of 
olaratumab.  However, given the previously acceptable toxicity profile of olaratumab in 
combination with doxorubicin in Study JGDG, it is not anticipated that this will result in any 
additional safety risk to the patients enrolled in this study.
From Cycle 3 through Cycle 7, patients will receive olaratumab at a dose of 15 mg/kg on Day 1 
and Day 8, in combination with doxorubicin 75 mg/m2 on Day 1 of a 21-day cycle, the same 
doses studied in Study JGDG.

6.2.
Summary of Study Design
Study JGDM is an open-label, single-arm, multicenter, multicountry Phase 1b study to 
enumerate whole blood CTCs and to characterize PDGFRand PDGFRand canonical ligands
(PDGF-A, B, C and D) expression changes pre- and post-olaratumab monotherapy in tumor 
tissue in patients with potentially resectable STS.
Patients are to be treated with 20 mg/kg of olaratumab on Day 1 and Day 8 of Cycle 1, followed 
by up to 6 cycles (Cycle 2 – Cycle 7) of combination therapy with olaratumab plus doxorubicin.  
For Cycle 2, olaratumab is to be dosed at 20 mg/kg on Day 1 and Day 8 and doxorubicin is to be 
dosed at 75 mg/m2 on Day 1.  For Cycle 3 – Cycle 7, olaratumab is to be dosed at 15 mg/kg on
Day 1 and Day 8 and doxorubicin is to be dosed at 75 mg/m2 on Day 1.  Each cycle of treatment 
is defined as an interval of 21 days.  Approximately 35 patients are to be enrolled.  
Starting with the first cycle of combination therapy (Cycle 2), the use of dexrazoxane (in a 10:1 
ratio vs. doxorubicin dose) to mitigate cardiotoxicity during treatment with doxorubicin is 
allowed at the investigator’s discretion and is recommended for all patients receiving 5 or more 
cycles of doxorubicin.

I5B-MC-JGDM(c) Phase 1 Oncology Protocol

LY3012207
Tissue biopsies are required pre- and posttreatment with olaratumab monotherapy.  The 
pretreatment tissue biopsy is to be performed within the screening period.  The posttreatment 
tissue biopsy is to be performed after completion of the lead-in cycle of olaratumab monotherapy
and prior to the initiation of combination therapy in Cycle 2. An optional third tissue biopsy (or 
tissue from a posttherapy surgical resection specimen) may be performed at the end of the 
patient’s study treatment.  If clinically feasible, the tissue biopsies should be taken from the same 
primary tumor lesion.  If the patient has an additional surgical resection, tissue from this 
procedure is requested.  Refer to Section 8.2.3.2 for details on tissue biopsies. 
Whole blood samples for CTC analyses are to be collected predose at Cycle 1 Day 1 (C1D1), at 
Cycle 1 Day 8 (C1D8), at Cycle 2 Day 1 (C2D1), at Cycle 2 Day 8 (C2D8), at Cycle 3 Day 1 
(C3D1), and at the end of the patient’s study treatment or at the time of surgical resection.  Refer 
to Section 8.2.3.1 for details on blood samples.
After 1 cycle of monotherapy, patients will receive combination therapy for up to 6 cycles or 
until evidence of progressive disease (PD), unacceptable toxicity, surgical resection, death, or 
other withdrawal criteria are met.  Patients who discontinue study treatment for reasons other 
than progression or surgical resection will be followed every 6 weeks (±7 days) until PD.
Refer to Attachment 1 for the Study Schedule.

is to be reported on the eCRF.  Patients who discontinue will have follow-up procedures 
performed as shown in the Study Schedule (Attachment 1).
If a patient withdraws informed consent, he or she must not be contacted unless he or she has 
explicitly provided permission and consent.  Lilly may continue to use previously collected 
medical research data prior to the withdrawal consistent with the original authorization.
6.3.1. Discontinuation of Patients Inadvertently Enrolled
The criteria for enrollment must be followed explicitly. If the investigator site identifies a patient 
who did not meet enrollment criteria and who was inadvertently enrolled, the sponsor must be 
notified.  If the sponsor identifies a patient who did not meet enrollment criteria and who was 
inadvertently enrolled, the investigator site will be notified. A discussion must occur between 
the sponsor clinical research physician (CRP) and the investigator to determine whether the 
patient may continue in the study, with or without IP.  Inadvertently enrolled patients may be 
maintained in the study and on IP when the Lilly CRP agrees with the investigator that it is 
medically appropriate for that patient. The patient may not continue in the study with or without 
IP if the Lilly CRP does not agree with the investigator’s determination that it is medically 
appropriate for the patient to continue. The investigator must obtain documented approval from 
the Lilly CRP to allow the inadvertently enrolled patient to continue in the study with or without 
IP.
6.3.2. Discontinuation of Patients from Study or Study Drug
The date of and the reason for discontinuation from study treatment will be collected for all 
patients; the date of discontinuation from study treatment (for any of the reasons listed below) is 
to be reported on the eCRF.  Patients who discontinue study treatment will have follow-up 
procedures performed as shown in the Study Schedule (Attachment 1).
In addition, patients will be discontinued from the study drug and/or from the study in the 
following circumstances:

Olaratumab is formulated in 10 mM histidine, 100 mM glycine, 50 mM sodium chloride, 75 mM 
mannitol, and 0.02% polysorbate-20, pH 5.5.  All excipients used in the formulation of 
olaratumab drug product are of pharmacopeial grade.
Where commercially available, doxorubicin hydrochloride will be purchased by the sites.  In the 
event that there are regional restrictions or supply limitations, doxorubicin may be provided to 
the sites by Lilly.
Where commercially available, dexrazoxane will be purchased by the sites.  In the event that 
there are regional restrictions or supply limitations, dexrazoxane may be provided to the sites by 
Lilly.
Clinical study materials will be labeled according to the country’s regulatory requirements.
7.1.2. Olaratumab
Olaratumab Drug Product:  The drug product must be stored under refrigeration at 2°C-8°C 
(36°F-46°F) with protection from direct light.  Do not freeze and/or shake olaratumab drug 
product.  Stability studies have demonstrated that the drug product can withstand transient 
excursion to room temperature without adverse effect; however, storage at this temperature is not 
recommended.
Please refer to the Pharmacy Manual for information on preparing the olaratumab dosing 
solution for infusion.
CAUTION:  Infusion-related reactions may occur during or following olaratumab administration 
(see Section 7.2.3.1.1.1 for a definition of Grade 3 and 4 IRRs).  During the administration of 
olaratumab, patients should be in an area with resuscitation equipment and treatments necessary 
for advanced life support and cardiopulmonary resuscitation, such as bronchodilators, 
vasopressor agents (for example, epinephrine), oxygen, glucocorticoids, antihistamines, and IV 
fluids.  A 1-hour Observation Period is required after the administration of the first and second 
cycles of olaratumab.  If no evidence of an IRR manifests during the initial 2 cycles of 
olaratumab, then no observation period is required for subsequent treatment cycles.  In the event 
that a Grade 1 or 2 IRR occurs after Cycle 2, the 1-hour observation period will be reinstituted
for a minimum of 2 cycles.  The reinstituted observation period may be suspended after 2 cycles 
if the patient shows no further signs or symptoms of an IRR.

7.1.3. Doxorubicin
Investigators should consult the approved doxorubicin hydrochloride package insert for complete 
prescribing information (including warnings, precautions, contraindications, adverse reactions, 
and dose modifications) and follow institutional procedures for the administration of 
doxorubicin.  If a patient should have an IRR to doxorubicin, the investigator should follow the 
manufacturer’s recommendations and clinical guidelines in the management of the patient.  
Doxorubicin 75 mg/m2 is administered IV.  The dose of doxorubicin should be reconstituted in 
100 mL of normal saline.  Administer doxorubicin as an IV injection or as an infusion in less 
than 60 minutes.  Decrease the rate of doxorubicin administration if erythematous streaking 
along the vein proximal to the site of infusion or facial flushing occurs.
Doxorubicin must be reconstituted prior to infusion.  The reconstituted solution is stable for 
7 days at room temperature and under normal room light and 15 days under refrigeration (2ºC-
8ºC [36ºF-46ºF]).  It should be protected from exposure to sunlight.
Parenteral drug products should be inspected visually for particulate matter and discoloration 
prior to administration, whenever solution and container permit.
Clinical study materials will be labeled according to the country’s regulatory requirements. 
See Section 7.5.1.1 for dexrazoxane administration.  Dexrazoxane should be started within 
30 minutes prior to the doxorubicin infusion.
7.2.

a
Premedicate all patients with the following (or equivalent) medications:  a histamine H1 antagonist (for example, 
diphenhydramine) and dexamethasone intravenously 30–60 minutes prior to the olaratumab doses on Days 1 and 
8 of Cycle 1.  For subsequent cycles, premedicate all patients with a histamine H1 antagonist (for example, 
diphenhydramine) intravenously 30-60 minutes prior to each dose of olaratumab.  Additional premedication may 
be provided at the investigator’s discretion.  Premedication must be provided in the setting of a prior Grade 1-2 
IRR, as detailed in Section 7.2.2 and Section 7.2.3.1.1.1.  All premedication administered must be adequately 
documented in the eCRF.
b
A 1-hour (+5 minutes) Observation Period is required after the administration of the initial 2 cycles of 
olaratumab.  During the Observation Period, collect vital signs 3 times:  1) within 15 minutes (+5 minutes) prior 
to olaratumab infusion, 2) within 1 hour (+5 minutes) after completion of the olaratumab infusion, and 3) within 
1 hour (+5 minutes) after completion of the doxorubicin infusion.  If no evidence of an IRR manifests during the 
initial 2 cycles of olaratumab, then no observation period is required for subsequent treatment cycles.  In the 
event an IRR occurs thereafter, then the 1-hour Observation Period should be reinstituted; see Section 7.1.2.  
Thereafter (Cycles 3+), obtain vital signs 2 times:  1) within 15 minutes (+5 minutes) prior to olaratumab 
infusion and 2) within 1 hour (+5 minutes) after completion of the doxorubicin infusion.
c
Administer doxorubicin according to institutional guidelines and/or clinical practice as an IV injection or as an 
infusion within 60 minutes.  Decrease the rate of doxorubicin administration if erythematous streaking along the 
vein proximal to the site of infusion or facial flushing occurs.  Infusion or injection start and end times will need 
to be recorded.  Starting with Cycle 2, dexrazoxane may be administered at a 10:1 ratio 
(dexrazoxane:doxorubicin) at the investigator’s discretion according to instructions provided in the pharmacy 
manual for this study, beginning within 30 minutes prior to the doxorubicin infusion for prevention of 
cardiotoxicity.  It is recommended that all patients receiving 5 or more cycles of doxorubicin receive 
dexrazoxane.
7.2.2. Premedication
Infusion-related reactions, including Grade 3-5 IRR events, have been observed with 
olaratumab. To date, Grade 3-5 IRR events have primarily occurred during the first cycle of 
olaratumab treatment.  Therefore, premedicate all patients with the following (or equivalent) 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 33
LY3012207
medications:  a histamine H1 antagonist (for example, diphenhydramine) and dexamethasone 
intravenously 30–60 minutes prior to the olaratumab doses on Days 1 and 8 of Cycle 1.  
For subsequent cycles, premedicate all patients with a histamine H1 antagonist (for example, 
diphenhydramine) intravenously 30-60 minutes prior to each dose of olaratumab.  
Premedication must be provided in the setting of a prior Grade 1 or 2 IRR, as detailed in Section 
7.2.3.1.1.1. All premedication administered must be adequately documented in the eCRF.
Given the emetogenic potential of doxorubicin, premedication with anti-emetics per institutional 
guidelines is recommended.  Additional premedication may be provided at investigator 
discretion.
If doxorubicin premedication is required prior to the doxorubicin infusion, this must be done 
after completion of the olaratumab infusion, not before the olaratumab infusion. This 
premedication may be administered immediately following the end of the observation period (if 
applicable) or after completion of the olaratumab infusion.
Starting with Cycle 2, dexrazoxane may be administered IV at a 10:1 ratio 
(dexrazoxane:doxorubicin) at the investigator’s discretion according to instructions provided in 
the pharmacy manual for this study, beginning no later than 30 minutes prior to each doxorubicin 
infusion for the prevention of cardiotoxicity. It is recommended that all patients receiving 5 or 
more cycles of doxorubicin receive dexrazoxane.
7.2.3. Dose Modifications
7.2.3.1.
Dose Delays, Modifications, and Discontinuations 
After treatment has been initiated, in order to start the next cycle, the following criteria must be
fulfilled:

ANC ≥1.0 × 103/L (1000/L; ≥1.0 × 109/L)
Note that in order to administer single-agent olaratumab on Day 8, ANC must 
be 750/L; 0.75 × 109/L.  If the ANC is 750/L, the Day 8 administration 
of olaratumab may be delayed for a maximum of 7 days.  If the ANC level has 
not increased to 750/L within 7 days, then the Day 8 olaratumab dose in 
that cycle should be skipped and dosing resumed on Day 1 of the following 
cycle if criteria for dosing are met.  If all dosing criteria are met, a delay or 
omission of the Day 8 olaratumab dose should not result in a delay of the 
Day 1 olaratumab dose of the following cycle. 

Platelets ≥100 × 103/L (100,000/L; ≥100 × 109/L)

Hemoglobin ≥8 g/dL

Creatinine clearance ≥45 mL/min (refer to Attachment 7 for the 
Cockcroft-Gault formula)

Proteinuria ≤1000 mg in 24 hours (if routine urinalysis indicates 
≥2+ proteinuria) (to be performed every other cycle)

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 34
LY3012207

Total bilirubin below ULN

AST and ALT ≤3.0 x ULN, or ≤5 x ULN if the transaminase elevation is due 
to liver metastases

Olaratumab-related AEs that are NCI-CTCAE Version 4.0 Grade <2 or 
equivalent severity to baseline
Delays:
In general, dose delays of 1 study drug (olaratumab or doxorubicin) due to toxicity guidances 
outlined in Sections 7.2.3.1.1 and 7.2.3.1.2 will not necessitate delays of the other study drug.
Treatment may be delayed for up to 21 days (1 equivalent cycle) to allow a patient sufficient 
time for recovery from study drug-related toxicity.  If a patient does not recover from the toxicity 
within 42 days (2 equivalent cycles) from Day 1 of the previous treatment cycle, then the patient 
must be discontinued from study therapy.
Any procedure or sample collection whose timing is related to olaratumab dosing is to be 
completed according to when the olaratumab dose was actually administered, not when that dose 
was expected to occur.  Samples whose adjusted timing would fall outside of the treatment cycle 
duration due to dose delay may be omitted.
Dose Modifications:
Any patient who requires a dose reduction will continue to receive the reduced dose for the 
remainder of the study.  Any patient who has had 2 dose reductions and who experiences a 
toxicity that would cause a third dose reduction must be discontinued from study drug.
In the event of an alteration in olaratumab dose due to an olaratumab-related toxicity, 
doxorubicin need not be altered, and the planned doxorubicin schedule should be maintained.
Similarly, olaratumab therapy need not be altered for doxorubicin-related toxicity.  An alteration 
in doxorubicin dose will always necessitate a corresponding change to dexrazoxane, if 
administered, in order to maintain a dosage ratio of 10:1 (dexrazoxane:doxorubicin).
Discontinuations:
In general, discontinuation of olaratumab will not necessitate discontinuation of doxorubicin.  In 
the event of discontinuation of olaratumab therapy due to an olaratumab-related toxicity or 
Grade 3 or 4 IRR, doxorubicin need not be altered, and the planned doxorubicin schedule may be 
maintained at the discretion of the investigator.  Discontinuation of doxorubicin will necessitate 
discontinuation of olaratumab.
Any changes in treatments being added to or removed from patient care will be recorded on the 
eCRF.
The following information (in this section and the following subsections) pertains to dose 
modifications and delays for and management of AEs of concern, which may or may not be 
associated with olaratumab therapy, including the following:

7.2.3.1.1. Olaratumab
7.2.3.1.1.1.
Infusion-Related Reactions
As with other therapeutic protein products, hypersensitivity reactions may occur during or 
following olaratumab administration.
For the initial 2 cycles of olaratumab treatment, it is mandatory that patients be closely 
monitored by the medical staff for signs and symptoms indicative of an IRR from the start of the 
infusion until at least 1 hour after the end of the infusion (see Table JGDM.1) in an area where 
emergency medical resuscitation equipment and other agents (such as epinephrine or
prednisolone equivalents) are available.  If no evidence of an IRR manifests during the initial 
2 cycles of olaratumab, then no observation period is required for subsequent treatment cycles.  
In the event an IRR occurs thereafter, then the 1-hour observation period should be reinstituted
(see Section 7.1.2).  
Olaratumab IRRs will be defined according to the NCI-CTCAE Version 4.0 definition of IRRs.
Symptoms occurring during or following infusion of investigational therapy may also be defined 
according to AE terms such as allergic reaction, anaphylaxis, or cytokine release syndrome 
(NCI-CTCAE Version 4.0 section “Immune system disorders”).  In the setting of symptoms 
occurring during or following infusion of investigational therapy, investigators are encouraged to 
use the AE term “IRR” and any additional terms (including those not listed here) that best 
describe the event.
For patients who experience a Grade 1 or 2 IRR, the infusion should be stopped and the patient
treated with the following (or equivalent) medications:  a histamine H1 antagonist (for example, 
diphenhydramine) and glucocorticoid (for example, dexamethasone) IV, acetaminophen, and 
oxygen (as indicated), according to standard medical practices.  After recovery, the infusion rate 
should be decreased by 50% for the duration of the infusion.  After a Grade 1 or 2 IRR, patients 
should be premedicated with the following (or equivalent) medications:  a histamine H1 
antagonist (for example, diphenhydramine) and glucocorticoid (for example, dexamethasone) IV, 
and acetaminophen, as appropriate, approximately 30-60 minutes prior to all subsequent 
olaratumab infusions.

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 36
LY3012207
A Grade 3 or 4 IRR will require immediate treatment, including the use of epinephrine, 
bronchodilators, and/or glucocorticoids for symptomatic bronchospasm, IV fluids and/or 
pressors for hypotension, and immediate and permanent discontinuation of olaratumab with 
appropriate supportive care.
If a patient experiences an IRR to olaratumab, all attempts should be made to obtain an 
anti-olaratumab antibody blood sample as close to the onset of the event as possible, at the 
resolution of the event, and 30 days (±3 days) following the event.  In addition, these same 
samples may be assessed for levels of olaratumab and for pharmacodynamic markers to provide 
information on the nature of the IRR.  The procedure for sample collection and handling is 
described in a separate procedural manual.
Section 7.1.3 provides information on doxorubicin and IRRs.
7.2.3.1.1.2.
Hematologic Toxicity

Nonhematologic Toxicity
Specific guidelines for dose adjustments in patients who experience olaratumab IRRs may be 
found in Section 7.2.3.1.1.1.
Table JGDM.3 provides general guidelines for dose modification for other nonhematologic 
toxicities related to olaratumab.  If more than 2 toxicity-related olaratumab dose reductions are 
required, treatment with this agent will be permanently discontinued.
Table JGDM.3.
General Guidelines for Olaratumab Dose Modification Due to 
Nonhematologic Toxicity Deemed Related to Olaratumab
Reaction Grade
Required Dose Modification
Grade 1
No dose modification is required.
Grade 2
At the investigator’s discretion, the patient may continue to receive olaratumab per protocol, 
provided that the event does not pose a serious health risk or is easily treated.
Grade 3 
For a Grade 3 toxicity not adequately controlled with appropriate supportive care, the dose 
must be withheld until toxicity is Grade ≤1 or has returned to pretreatment baseline; then 
treatment may resume at a reduced dose of 12 mg/kg (15 mg/kg if the toxicity occurs during 
Cycle 1 or Cycle 2).  If toxicity recurs after therapy resumes, a second dose reduction (to 
10 mg/kg) is permitted.
Grade 4
The dose must be withheld until dose toxicity is ≤Grade 1 or has returned to baseline.  
Permanent discontinuation should be considered for any patient experiencing Grade 4 
nonhematological toxicity assessed as related to olaratumab.  However, if resumption of 
dosing is deemed appropriate by the investigator, treatment may resume only after 
consultation with the Lilly study physician, with the dose reduced to 10 mg/kg (15 mg/kg if 
the toxicity occurs during Cycle 1 or Cycle 2).  If Grade 4 toxicity recurs after therapy 
resumes, olaratumab treatment will be discontinued.
7.2.3.1.2. Doxorubicin
7.2.3.1.2.1.
Hematologic Toxicity
Doxorubicin will not be administered after the initial dose if the patient’s ANC is <1000 cells/L 
or if the platelet count is <100,000 cells/L.  When necessary, the next treatment cycle should be 
delayed until the ANC is ≥1000 cells/L and the platelet count is ≥100,000 cells/L and 
nonhematologic toxicities have resolved.  For patients who experience ≥Grade 3 neutropenic 
fever or infection or Grade 4 neutropenia without fever lasting more than 1 week, doxorubicin 
should be reduced to 75% of the starting dose (that is, to approximately 60 mg/m2).  If a patient 
experiences a second incidence of neutropenic fever/infection or has another episode of Grade 4 
neutropenia lasting >1 week, then a second dose reduction to 45 mg/m2 will be necessary.  
Therapeutic and prophylactic use of pegfilgrastim (Neulasta®) or other G-CSFs will be allowed 
per current American Society of Clinical Oncology (ASCO; Smith et al. 2006) and National 
Comprehensive Cancer Network (NCCN) guidelines (NCCN 2014).  For patients with Grade 4 
ANC without fever/infection lasting less than 1 week, retreatment will be allowed at the 
investigator’s discretion with the full dose of doxorubicin (75 mg/m2) with recommended use of 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 38
LY3012207
G-CSFs per current ASCO guidelines (Smith et al. 2006).  See Table JGDM.4 for doxorubicin 
dose modification for neutropenia.

At pretreatment:
If  Grade ≥3 neutropenic fever/infection has occurred
Approximately 60 mg/m2 doxorubicin.
If Grade 4 neutropenia lasting longer than 1 week 
has occurred 
Approximately 60 mg/m2 doxorubicin.
Grade 4 ANC without fever/infection
Retreatment with doxorubicin at full dose at 
investigator’s discretion with recommended use of 
prophylactic G-CSFs.
Second incidence of either:  
1) Grade ≥3 neutropenic fever/infection
2) Grade 4 neutropenia lasting longer than 1 week
Second dose reduction to 45 mg/m2.
Abbreviations:  ANC = absolute neutrophil count; G-CSF = granulocyte colony-stimulating factor.
7.2.3.1.2.2.
Cardiovascular Toxicity
Cardiotoxicity is a recognized risk of doxorubicin that increases with higher cumulative drug 
exposure.  Cardiac monitoring is conducted by a combination of monitoring of clinical 
parameters, ECG, and ECHO/MUGA scans.
Electrocardiogram changes, arrhythmias, tachycardia, and/or chest pain should be managed 
according to clinical practice based on the specific findings.
Patients will undergo baseline LVEF determination by ECHO or MUGA scan.  This evaluation 
may be repeated at any time during the study if clinically indicated.  If there is a decrease in 
LVEF of 10% and below the lower limit of normal, if there is an absolute decrease of 20%, or 
if the absolute LVEF decreases to or below 40%, then doxorubicin will be discontinued.  
Doxorubicin should also be discontinued if the patient develops Grade 3 or 4 left ventricular 
systolic dysfunction (symptomatic congestive heart failure).  All such changes should be 
reported as AEs.  If doxorubicin is discontinued for the above changes in LVEF, then olaratumab 
must be discontinued as well (see Section 7.2.3.1).  
The diagnostic method used at baseline for cardiovascular assessments (for example, ECHO or 
MUGA scans) should be the same method used throughout the study, unless there is clinical or 
instrumental evidence that further investigations are needed.
7.2.3.1.2.3.
Hepatic Impairment
Doxorubicin is contraindicated in patients with severe hepatic impairment (Child-Pugh Class C 
or total serum bilirubin >5.0 mg/dL).  Refer to Section 7.2.3.1 for additional information.  

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 39
LY3012207
7.2.3.1.2.4.
Nonhematologic Toxicity
Permanent discontinuation of doxorubicin should be considered for any patient experiencing 
Grade 4 nonhematologic toxicity assessed as related to doxorubicin.  If the investigator feels re-
dosing of doxorubicin is appropriate (except for Grade 4 cardiotoxicities and Grade 4 bilirubin 
increase which require mandatory discontinuation [see Section 7.2.3.1.2.2 and 
Section 7.2.3.1.2.3]), treatment may only resume after consultation with the Lilly study 
physician, with the dose reduced to 60 mg/m² (or less if agreed by the investigator and Lilly 
physician). If Grade 4 toxicity recurs after therapy resumes, doxorubicin treatment will be 
permanently discontinued.
For appropriate management of cardiac toxicities and hepatic impairment, refer to Section 
7.2.3.1.2.2 and Section 7.2.3.1.2.3. 
7.3.
Method of Assignment to Treatment
Patients who meet all criteria for enrollment will be assigned to receive treatment.  After the 
patient signs the ICF, the site will register the patient in the Interactive Web Response System 
(IWRS), which is web-based and accessible 24 hours a day.  The IWRS registration consists of 
assigning the patient a unique study identification number.  Once the patient is registered through 
the IWRS, he/she is considered to be enrolled in the study.  
7.3.1. Selection and Timing of Doses
A cycle is defined as an interval of 21 days (a cycle may be delayed up to 3 days due to holidays, 
weekends, bad weather, or other unforeseen circumstances without being counted as a protocol 
deviation). 
The dose of olaratumab to be administered will be determined by measuring the patient’s weight 
in kilograms on Day 1 and Day 8 of each cycle.  The dose of doxorubicin to be administered will 
be determined by calculating the patient's body surface area at the beginning of each cycle.  If the 
patient’s weight does not fluctuate by 10% (increase or decrease) from the weight used to 
calculate the prior dose, the olaratumab dose will not need to be recalculated.  A 5% variance in 
the calculated total dose will be allowed for ease of dose administration.
A patient may continue to receive study treatment until he or she has received a maximum of 
6 cycles of olaratumab in combination with doxorubicin, or until he or she meets 1 or more of 
the specified reasons for discontinuation (as described in Section 6.3.2).
7.4.
Blinding
This is an open-label study.
7.5.
Concomitant Therapy
All concomitant medications should be recorded throughout the patient’s participation in the 
study.
Concomitant medications and supportive care therapies must also be documented at the time of 
discontinuation and at the 30-day short-term follow-up visit.

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 40
LY3012207
With the exceptions listed in the sections below, no other chemotherapy, investigational 
medications, other anticancer therapy, immunotherapy, hormonal cancer therapy, radiation
therapy, surgery for cancer, or investigational medications will be permitted while patients are on 
study treatment.
Bisphosphonate osteoclast inhibitors (for example, zoledronic acid or pamidronate) for treatment 
of bone metastases will be permitted while patients are on study treatment.  However, the 
osteoclast inhibitor denosumab is a monoclonal antibody and could confound safety analysis in 
the study if the patient experiences a hypersensitivity reaction to denosumab. Therefore, 
concomitant use of denosumab will not be permitted.
Appropriate documentation for all forms of premedications, supportive care, and concomitant 
medications (for example, medications such as sedatives, antibiotics, analgesics, antihistamines, 
corticosteroids, or erythropoietin; procedures such as paracentesis, or thoracentesis; or blood 
products such as blood cells, platelets, or fresh frozen plasma transfusions) must be captured on 
the eCRF.
If doxorubicin premedication is required prior to the doxorubicin infusion, this must be done 
after the completion of olaratumab infusion, not before the olaratumab infusion.
7.5.1. Supportive Care
Patients should receive full supportive care, if necessary.  Patients will receive supportive care as 
judged by their treating physician.  If it is unclear whether a therapy should be regarded as 
supportive care, the investigator should consult with the Lilly CRP.  Use of any supportive care 
therapy must be captured on the eCRFs.
7.5.1.1.
Dexrazoxane
Starting with the first cycle of combination therapy (that is, Cycle 2), dexrazoxane may be 
administered IV at the investigator’s discretion according to instructions provided in the 
pharmacy manual for this study, beginning within 30 minutes prior to each doxorubicin infusion 
for the prevention of cardiotoxicity.  It is recommended that all patients receiving 5 or more 
cycles of doxorubicin receive dexrazoxane.  Investigators should consult the dexrazoxane 
information provided in the pharmacy manual for this study for administration information 
(including warnings, precautions, contraindications, adverse reactions, and dose modifications).
As the dose of dexrazoxane administered is dependent on the dose of doxorubicin administered, 
any dose modifications to doxorubicin will require a corresponding dose modification to 
dexrazoxane in order to maintain a dosage ratio of 10:1 (dexrazoxane:doxorubicin).
7.5.1.2.
Granulocyte-Colony Stimulating Factors and Erythroid Growth Factors
Following the first dose of doxorubicin treatment, the use of G-CSFs such as pegfilgrastim and 
erythroid stimulating factors (for example, erythropoietin) are permitted, including prophylactic 
use, during investigational therapy at the discretion of the investigator, according to ASCO 
guidelines (Smith et al. 2006) and NCCN guidelines (NCCN 2014).

I5B-MC-JGDM(c) Phase 1 Oncology Protocol

LY3012207
7.5.1.3.
Transfusion of Blood Products
Transfusions of red blood cells, platelets, or other blood products are permitted at the 
investigator’s discretion, but may not be used to meet hematologic criteria for inclusion in the 
study (refer to Section 6.1.1, inclusion criterion #9).
7.5.1.4.
Anti-emetic Therapy
Both prophylactic and symptom-directed anti-emetic therapy are recommended and should be 
used in accordance with institutional guidelines (when existent) and/or at investigator’s 
discretion.
7.5.2. Prohibited Therapies
Additional concurrent chemotherapy, radiation therapy, biologic response modifiers, or other 
investigational or approved anticancer agents may not be administered to patients on this study.  
Palliative radiation to symptomatic sites of disease will not be permitted while on study.
7.5.2.1.
Effect of CYP3A4, CYP2D6, and P-gp Inhibitors and Inducers on 
Doxorubicin
Doxorubicin is a major substrate of cytochrome P450 (CYP)3A4 and CYP2D6, and P-
glycoprotein (P-gp).  Clinically significant interactions have been reported with inhibitors of 
CYP3A4, CYP2D6, and/or P-gp (for example, verapamil), resulting in increased concentration 
and clinical effect of doxorubicin.  Inducers of CYP3A4 (for example, phenobarbital, phenytoin, 
St. John’s Wort) and P-gp inducers may decrease the concentration of doxorubicin.  Avoid 
concurrent use of doxorubicin with inhibitors and inducers of CYP3A4, CYP2D6, or P-gp.  
Attachment 9 provides a list of these inhibitors and inducers. 
7.6.
Treatment Compliance
The study medication will be administered only at the investigational sites by the authorized 
study site personnel.  As a result, treatment compliance is ensured.  Treatment compliance will 
be monitored by drug accountability records, and treatment administration data are recorded in 
the patient’s medical record and eCRF.  An investigator is required to prepare, maintain, and 
record all observations and other data pertinent to the investigation on each individual treated in 
this clinical trial.  All data reported on the eCRF must be derived from source documents and be 
consistent with the source documents.
7.6.1. Evaluable Patients
Evaluable patients are those with adequate biomarker samples who have a baseline (pre-
monotherapy) and at least 1 postbaseline measurement. Patients who withdraw from the study 
before receiving study drug will be replaced and will not be included in the safety or primary 
objective assessments.  Safety analyses will be conducted on all patients who have received at 
least 1 dose of study drug.
If the patient is noncompliant during olaratumab monotherapy (Cycle 1) and does not undergo 
the post-olaratumab monotherapy biopsy or the C1D1 pre-dose and C2D1 predose whole blood 
sample collection due to reasons other than drug-related toxicity, he or she will be considered 
nonevaluable for the primary objective.  These patients may be replaced to ensure that 35

I5B-MC-JGDM(c) Phase 1 Oncology Protocol

LY3012207
patients complete the pre-treatment tissue biopsy, the C1D1 pre-dose whole blood sample 
collection, 1 cycle of olaratumab monotherapy, and the post-olaratumab monotherapy biopsy,
and the associated C2D1 predose whole blood sample collection.

8. Safety, Pharmacokinetic, Pharmacodynamic, and 
Efficacy Data Collection
8.1.
Safety Evaluations
8.1.1. Safety Data Collection and Review
Investigators are responsible for monitoring the safety of patients who have entered into this 
study and for alerting Lilly or its designee to any event that seems unusual, even if this event 
may be considered an unanticipated benefit to the patient.  
The investigator is responsible for the appropriate medical care of the patient during the study.
The investigator remains responsible for following, through an appropriate health care option,
AEs that are serious, considered related to study treatment or the study, or that caused the patient 
to discontinue before completing the study.  The patient should be followed until the event is 
resolved, the event is no longer considered to be drug-related, the event becomes stable or 
returns to baseline, a new treatment is initiated for the patient, or the patient dies or is lost to 
follow-up.  Frequency of AE and SAE follow-up evaluation is left to the discretion of the 
investigator.
The timing of all safety evaluations is shown in the Study Schedule (Attachment 1).  Section 
8.1.2.4 presents a summary of AE and SAE reporting guidelines.  Table JGDM.5 shows the 
database or system used to store AE and SAE data.
8.1.2. Adverse Events
Lilly has standards for reporting AEs that are to be followed regardless of applicable regulatory 
requirements that may be less stringent.  A clinical study AE is any untoward medical occurrence 
in a patient or clinical investigation subject administered a pharmaceutical product and which 
does not necessarily have a causal relationship with this treatment.  An AE can therefore be any 
unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or 
disease temporally associated with the use of medicinal (investigational) product, whether or not 
related to the medicinal (investigational) product.  Any clinically significant findings from labs, 
vital sign measurements, and so on that occur should also be reported to Lilly or its designee as 
an AE.  Lack of drug effect is not an AE in clinical studies because the purpose of the clinical 
study is to establish drug effect.
The investigator, monitor, and sponsor will review the collected data regularly for evidence of 
AEs. All patients will be assessed routinely for AEs as outlined in the Study Schedule
(Attachment 1).  The NCI-CTCAE Version 4.0 will serve as the reference document for 
choosing appropriate terminology for, and grading the severity of, all AEs and other symptoms.  
All AEs observed will be graded using CTCAE Version 4.0. For AEs without matching 
terminology within the NCI-CTCAE Version 4.0 criteria, the investigator will be responsible for 
selecting the appropriate System Organ Class and assessing severity grade based on the intensity 
of the event.  Note that both CTCAE term (actual or coded) and severity grade must be selected 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 44
LY3012207
by study site personnel and collected on the case report form (CRF).  This collection is in 
addition to verbatim text used to describe the AE.
In addition to collecting the AE verbatim, the CTCAE term, and the CTCAE severity grade, AE 
verbatim text will also be mapped by the sponsor or designee to corresponding terminology 
within the Medical Dictionary for Regulatory Activities (MedDRA) dictionary.
Cases of pregnancy that occur during maternal or paternal exposures to study should be reported.  
Data on fetal outcome and breastfeeding should be collected, if feasible, for regulatory reporting 
and drug safety evaluation.
Upon documentation of pregnancy, the patient must be removed from the study and treatment 
with study drugs must be stopped immediately.
For all enrolled patients, study site personnel will record the occurrence and nature of each 
patient’s preexisting conditions, including clinically significant signs and symptoms of the 
disease under treatment in the study.  While the patient is on study, site personnel will record any 
change in these preexisting condition(s) and the occurrence and nature of any AEs.  In addition,
all AEs related to protocol procedures will be reported to Lilly or designee.
If a patient’s dosage is reduced or treatment is discontinued as a result of an AE, study site 
personnel must clearly report to Lilly or its designee via eCRF the circumstances and data 
leading to any such dosage reduction or discontinuation of treatment. 
Investigators will be instructed to report to Lilly or its designee their assessment of the potential 
relatedness of each AE to protocol procedure and/or study drug via eCRF.
The investigator decides whether he or she interprets the observed AEs as either related to 
disease, study medication, study procedure, or other concomitant treatment or pathologies.  To 
assess the relationship of the AE to the study drug, the following terminologies are defined:

Related:  a direct cause and effect relationship between the study treatment and 
the AE is likely.

Possibly related:  a cause and effect relationship between the study treatment and 
the AE has not been demonstrated at this time and is not probable, but is also not 
impossible.

Unrelated:  without question, the AE is definitely not associated with the study 
treatment.
As per Lilly’s standard operating procedures, all “related” and “possibly related” AEs and SAEs 
will be defined as related to study drug.
8.1.2.1.
Serious Adverse Events
Planned surgeries should not be reported as SAEs unless the underlying medical condition has 
worsened during the course of the study.
An SAE is any AE during this study that results in one of the following outcomes:

death

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 45
LY3012207

initial or prolonged inpatient hospitalization (except for study drug 
administration)

a life-threatening experience (that is, immediate risk of dying)

persistent or significant disability/incapacity

congenital anomaly/birth defect

considered significant by the investigator for any other reason.
Important medical events that may not result in death, be life-threatening, or require 
hospitalization may be considered SAEs when, based on appropriate medical judgment, they 
may jeopardize the patient and may require medical or surgical intervention to prevent one of the 
outcomes listed in this definition. 
Serious adverse events due to disease progression, including death, should not be reported unless 
the investigator deems them to be possibly related to the study drug.
Study site personnel must alert Lilly or its designee of any SAE within 24 hours of investigator 
awareness of the event via a sponsor-approved method.  If alerts are issued via telephone, they
are to be immediately followed with official notification on study-specific SAE forms.  This 24-
hour notification requirement refers to the initial SAE information and all follow-up SAE 
information.  Attachment 5 provides recommendations for reporting SAEs.
When a condition related to study treatment necessitates medical or surgical intervention to 
preclude either permanent impairment of a body function or permanent damage to a body 
structure, the serious outcome of “required intervention” will be assigned.
If an investigator becomes aware of SAEs occurring after the patient’s participation in the trial 
has ended, and the investigator believes that the SAE is related to a protocol procedure or study 
drug, the investigator should report the SAEs to the sponsor and the SAEs will be entered in the
Lilly Safety System.
Information on SAEs expected in the study population independent of drug exposure and that 
will be assessed by the sponsor in aggregate periodically during the course of the trial may be 
found in the IB.  
8.1.2.2.
Adverse Event and Serious Adverse Event Reporting
Data on SAEs that occur before the end of trial will be stored in the collection database and in 
the Lilly Safety System.
8.1.2.2.1. Prior to Administration of Study Drugs
Although all AEs after signing the ICF are recorded in the CRF, SAE reporting begins after the 
patient has signed the ICF and has received study treatment. However, if an SAE occurs after 
signing the ICF, but prior to receiving study treatment, it needs to be reported ONLY if it is 
considered reasonably possibly related to study procedure.
8.1.2.2.2. On Study Treatment
All AEs and SAEs, regardless of relatedness to study drugs or protocol procedures, occurring 
while the patient is receiving study drug must be reported to Lilly or its designee.  A patient is 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 46
LY3012207
considered to be receiving study drug from the time he/she receives the first dose of study drug 
to when he/she receives the last dose of study drug.
8.1.2.2.3. Follow-Up Visit
All AEs and SAEs, regardless of relatedness to study drugs or protocol procedures, occurring 
during the follow-up visit (Visit 801) must be reported to Lilly or its designee. The follow-up 
visit begins the day after the patient and the investigator agree that the patient will no longer 
continue study treatment.  At the end of the follow-up visit, the patient will be required to have 
specific safety assessments (Attachment 1).  The timing of these safety assessments is 30 ± 7
days after the last dose of study drug.
Following the safety assessments, which mark the end of the follow-up visit (Visit 801), the 
patient will continue into long-term follow-up until disease progression.  Any ongoing AE or 
SAE considered possibly related to study drug should be followed during the long-term follow-
up.  In this instance, the patient should be followed in subsequent follow-up visits (Visit 802, 
Visit 8XX) until the event is resolved, or is no longer considered to be drug-related, or becomes 
stable, or returns to baseline, a new treatment is initiated for the patient, or the patient dies or is 
lost to follow-up.
If it is deemed to be in the best interest of the patient to start a new anticancer treatment prior to 
the scheduled end of the follow-up visit, the follow-up visit duration may be shortened. In this 
case, the follow-up assessments should be completed prior to the initiation of the new therapy.
After the follow-up visit (Visit 801), AEs are not required to be reported unless the investigator 
feels the AEs were related to either study drug, drug delivery system, or a protocol procedure. If 
an investigator becomes aware of any SAEs believed to be related to protocol procedures or 
study drug, the investigator should report the SAE to the sponsor, and the SAE will be entered in 
the Lilly Safety System.
8.1.2.3.
Suspected Unexpected Serious Adverse Reactions
Suspected unexpected serious adverse reactions (SUSARs) are SAEs that are not listed in the
DCSI and that the investigator identifies as related to study drug or procedure.  The United States 
21 CFR 312.32, the European Union Clinical Trial Directive 2001/20/EC, and the associated 
detailed guidances or national regulatory requirements in participating countries require the 
reporting of SUSARs.  Lilly has procedures that will be followed for the recording and expedited 
reporting of SUSARs that are consistent with global regulatory regulations and the associated 
detailed guidances.
8.1.2.4.

8.1.3. Other Safety Measures
8.1.3.1.
Electrocardiograms
For each patient, 12-lead ECGs will be collected according to the Study Schedule (Attachment 
1).  Patients must be supine for approximately 5 to 10 minutes before ECG collection and remain 
supine but awake during ECG collection.
Electrocardiograms may be obtained at additional times, when deemed clinically necessary.  
Collection of more ECGs than expected at a particular time point is allowed when needed to 
ensure high quality records.
Electrocardiograms will be interpreted by a qualified physician (the investigator or qualified 
designee) at the site as soon after the time of ECG collection as possible, and ideally while the 
patient is still present, to determine whether the patient meets entry criteria and for immediate 
patient management, should any clinically relevant findings be identified.  Section 9.2.2 provides 
additional information on ECG collection and storage. 
After enrollment, if a clinically significant increase in the QT/corrected QT interval (QTc) from 
baseline, or other clinically significant quantitative or qualitative change from baseline, is 
present, the investigator will assess the patient for symptoms (for example, palpitations, near 
syncope, syncope) and to determine if the patient can continue in the study.  The investigator or 
qualified designee is responsible for determining if any change in patient management is needed 
and must document his/her review of the ECG printed at the time of evaluation.

on 2 consecutive R waves on ECG.
8.1.3.2.
Echocardiograms/MUGA Scans
An ECHO or MUGA scan is required within 28 days prior to enrollment for all patients.  
Thereafter, ECHO or MUGA scans, whichever technique was used initially (as described in 
Section 7.2.3.1.2.2), must be performed at the end of Cycles 5 and 7, and when clinically
indicated.  For patients with LVEF <50% or other cardiac dysfunction, perform more frequently, 
if clinically indicated. After Cycle 7 (for patients with resting LVEF ≥50%), an ECHO or 
MUGA scan should be obtained at the 30-day follow-up visit (refer to the Study Schedule
[Attachment 1]).  
Patients who stop doxorubicin prior to Cycle 7 will undergo cardiac monitoring assessment at the 
30-day follow-up visit (refer to the Study Schedule [Attachment 1]) with whichever technique 
(ECHO or MUGA scan) was used initially (as described in Section 7.2.3.1.2.2).
8.1.4. Safety Monitoring
The Lilly CRP/clinical research scientist (CRS) will monitor safety data throughout the course of 
the study, including a safety review conducted after the first 5 patients have completed Cycle 2 
of treatment. 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 49
LY3012207
Lilly will review SAEs within time frames mandated by company procedures.  The Lilly CRP 
will, as is appropriate, consult with the functionally independent Global Patient Safety 
therapeutic area physician or clinical scientist, and review:

trends in safety data

laboratory analytes

AEs, including cardiac events such as:
o
myocardial failure or dysfunction
o
myocardial ischemia or infarction
o
arrhythmias
o
cardiovascular insufficiency

adverse events of special interest (AESIs; as defined in Section 8.1.4.1)

If a study patient experiences elevated ALT 5× ULN and elevated total bilirubin 
2× ULN, clinical and laboratory monitoring should be initiated by the investigator. 
Details for hepatic monitoring depend upon the severity and persistence of observed laboratory 
test abnormalities. To ensure patient safety and comply with regulatory guidance, the 
investigator is to consult with the Lilly CRP/CRS regarding collection of specific recommended 
clinical information and follow-up laboratory tests (see Attachment 3).  
8.1.4.1.
Adverse Events of Special Interest
Adverse events of special interest are events that have been identified as safety signals during 
preclinical or early clinical trials or based on class effects of similar drugs.  These events will be 
monitored prospectively in the clinical developmental program.  Each event is defined by a 
careful assessment and grouping of individual related MedDRA preferred terms. 
AESI for olaratumab
IRRs
AESI for combination of olaratumab and doxorubicin
Cardiac arrhythmias and cardiac dysfunction
Refer to Section 7.2.3 for special treatment considerations for dose delay, modifications, and 
discontinuations from olaratumab and/or doxorubicin, including AEs of concern or AESIs.
8.1.5. Complaint Handling
Lilly collects complaints on study drugs used in clinical studies in order to ensure the safety of 
study participants, monitor quality, and facilitate process and product improvements.
Patients will be instructed to contact the investigator as soon as possible if he or she has a 
complaint or problem with the IP so that the situation can be assessed.
Complaints related to doxorubicin and/or dexrazoxane or concomitant drugs are reported directly 
to the manufacturers of those drugs in accordance with the package insert.

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 50
LY3012207
The investigator or his/her designee is responsible for handling the following aspects of the 
complaint process in accordance with the instructions provided for this study:

recording a complete description of the product complaint reported and any associated 
AEs using the study-specific complaint forms provided for this purpose

faxing the completed product complaint form within 24 hours to Lilly or its designee
If the investigator is asked to return the product for investigation, he/she will return a copy of the 
product complaint form with the product.
8.2.
Sample Collection and Testing
Attachment 1 lists the schedule for sample collections in this study.  
Attachment 2 lists the specific tests that will be performed for this study.  
Attachment 4 provides details on and timing for the collection of biomarker, PK, and 
immunogenicity blood samples.
8.2.1. Samples for Study Qualification and Health Monitoring
Blood, urine, and tissue samples will be collected to determine whether patients meet 
inclusion/exclusion criteria and to monitor patient health.
Investigators must document their review of each laboratory safety report.
Samples collected for specified laboratory tests will be destroyed within 60 days of receipt of 
confirmed test results.  Tests are run and confirmed promptly whenever scientifically 
appropriate.  When scientific circumstances warrant, however, it is acceptable to retain samples 
to batch the tests run, or to retain the samples until the end of the study to confirm that the results 
are valid.  Certain samples may be retained for a longer period, if necessary, to comply with 
applicable laws, regulations, or laboratory certification standards.
Section 8.2.3.1 specifies blood sample requirements for study qualification.  
Section 8.2.3.2 specifies tumor tissue sample requirements for study qualification. 
8.2.2. Samples for Drug Concentration Measurements 
Pharmacokinetics
Pharmacokinetic samples will be collected as specified in the Biomarker, PK, and 
Immunogenicity Blood Sampling Schedule (Attachment 4). 
8.2.2.1.
Pharmacokinetic Samples
At the visits and times specified in the Study Schedule (Attachment 1) and in the Biomarker, PK, 
and Immunogenicity Blood Sampling Schedule (Attachment 4), samples of approximately 3 mL 
of whole blood will be drawn into tubes to perform olaratumab serum PK measurements.  A 
maximum of 3 samples per drug may be collected at additional time points during the study if 
warranted and agreed upon between both the investigator and Lilly.  Instructions for the 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 51
LY3012207
collection and handling of blood samples will be provided by Lilly.  The actual date and time 
(24-hour clock time) of each sampling will be recorded.
These samples will be analyzed at laboratories designated by the sponsor.  Serum concentrations 
of olaratumab will be assayed using a validated enzyme-linked immunosorbent assay method.  
Bioanalytical samples collected to measure IP concentration will be retained for a maximum of 
1 year following last patient visit for the study and will be stored at facilities designated by Lilly.
8.2.3. Samples for Biomarkers
As part of Lilly’s ongoing efforts to understand the relationship between cancer, genetics, and
response to therapy, this study will analyze biomarkers relevant to drug targets, disease process, 
pathways associated with STS and/or cancer-related conditions, immune cells/immune and 
tumor microenvironment functioning within the disease state and MOA of olaratumab or 
doxorubicin. 
The primary objectives of this study are to enumerate whole blood CTCs and to characterize 
PDGFRα, PDGFRβ, and canonical ligands (PDGF-A, B, C, and D) expression changes pre- and 
post-olaratumab monotherapy in tumor tissue in patients with potentially resectable STS.  
There will be mandatory collection of tumor tissue samples pre- and post-olaratumab 
monotherapy and an optional collection of tumor tissue at the end of the patient’s study 
treatment, or when the patient undergoes a surgical resection, for study objectives relating to 
PDGFRexpression and related pathways, and to the biomarkers in the primary objective and 
clinical outcomes.  The study may be used for related research methods or validation of 
diagnostic tools or assays.
Collection of samples for biomarker research is a mandatory part of this study.  Blood and tissue
samples will be collected.  
Required samples for biomarker research to be collected from all patients in this study are the 
following:

blood (see Section 8.2.3.1 and Section 8.2.4)

tumor tissue (see Section 8.2.3.2)
Sample collection including blood and tumor tissue will occur at specified time points as 
indicated in the Study Schedule (Attachment 1). These samples are also described in the 
following sections.
It is possible that biomarker data has already been generated from samples that were collected 
and analyzed prior to enrolling in this trial.  This may include data generated from genetic 
analyses.  If available, this data may be requested from medical records for use in the research 
described in the following sections.
Samples may be stored for a maximum of 15 years following last patient visit for the study.

I5B-MC-JGDM(c) Phase 1 Oncology Protocol

LY3012207
8.2.3.1.
Blood Samples
Whole blood samples are required for all patients in order to participate in this study for 
biomarker research:

newly obtained peripheral whole blood specimens will be collected 
specifically to enumerate CTCs.  These specimens will be collected at C1D1 
(predose), C1D8 (predose), C2D1 (predose), C2D8 (predose), C3D1 
(predose), and at the end of the patient’s study treatment or at the time of 
surgical resection.  Refer to Attachment 4 for details. 

blood (ethylenediaminetetraacetic [EDTA] plasma, serum) samples for 
nonpharmacogenetic biomarker research will be collected.  Refer to 
Attachment 4 for details.
Newly obtained peripheral whole blood specimens are to be collected specifically to enumerate 
CTCs.  Sequentially collected blood specimens will be used for CTC detection and enumeration.  
The primary analysis of these samples will be focused on the relationship between pre-
olaratumab monotherapy and on-treatment (post-olaratumab monotherapy treatment) CTC 
counts. These samples may be used for other exploratory analyses and further molecular 
characterization.
Additional blood (EDTA plasma, serum) samples for nonpharmacogenetic biomarker research 
will be collected.  These samples will be examined for biomarkers related to STS, immune 
cells/immune and tumor microenvironment functioning within the disease state and/or cancer-
related conditions, variable response to olaratumab and/or doxorubicin, and the MOA of 
olaratumab or doxorubicin.  Potential pharmacodynamics and/or circulating markers may 
include, but are not limited to, PDGF receptors, canonical ligands (PDGF-A, B, C, and D), and 
downstream signaling pathways.  Biomarker assays may be performed on these samples to 
evaluate systemic immune modulation and changes in immune cell infiltration, activation, 
modulation, microenvironment, and changes in stromal and tumor biology in response to study 
treatment.
All samples will be coded with the patient number.  These samples and any data generated can 
be linked back to the patient only by the study site personnel.  Samples will be retained for a 
maximum of 15 years after the last patient visit for the study at a facility selected by the sponsor.  
This retention period enables use of new technologies, response to questions from regulatory 
agencies, and investigation of variable response that may not be observed until later in the drug 
development or when the drug is commercially available for a shorter period if local regulations 
and/or ERBs impose shorter time limits.
8.2.3.2.
Tumor Tissue 
Collection of the following tumor tissue samples is mandatory for all patients:

newly obtained biopsy specimens taken from the primary tumor lesion pre- and post-
olaratumab monotherapy treatment will be collected.  The pretreatment tissue biopsy is to 
be performed within the screening period.  The posttreatment tissue biopsy is to be 
performed after completion of the lead-in cycle of olaratumab monotherapy and prior to 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol

LY3012207
the initiation of combination therapy (Cycle 2).  Refer to Attachment 1 for additional 
details.  If clinically feasible, the biopsies should be taken from the same primary tumor 
lesion. 
Collection of the following tumor tissue samples is optional for all patients:

biopsy specimen collected at the end of the patient’s study treatment.  Refer to
Attachment 1 for additional details.  If clinically feasible, this biopsy should be taken 
from the same primary tumor lesion.

tumor tissue from any post-therapy surgical resection may also be collected and provided.
While this specimen is optional, it is expected this sample will be sent for analysis.
Sites should examine samples to determine adequacy of tumor tissue using their local laboratory 
procedures prior to the first dose of olaratumab monotherapy and again prior to the first dose of 
combination therapy.  If additional tumor biopsies are collected as part of clinical care, they 
should be submitted, along with local pathology reports, for further analysis. 
Details for the handling and shipping of the tumor tissue will be provided by Lilly in a separate 
document.  The tissue samples will be obtained using appropriate method.  Tumor tissue should 
be submitted as a newly acquired excisional or core needle (minimum 18 gauge) biopsy in 
formalin (10% neutral buffered).  Cytological or fine-needle aspiration specimens are not 
acceptable.  Due diligence should be used to make sure that tumor sample (not a normal adjacent 
or a tumor margin sample) is provided.  Pathology reports accompanying tissue may also be 
requested.  The reports must be coded with the patient number.  Personal identifiers, including 
the patient’s name and initials, must be removed from the institutional pathology notes prior to 
submission.  
Collected tumor samples will be used for research on the drug targets, disease process, pathways 
associated with STS and/or cancer-related conditions, immune cells/immune and tumor 
microenvironment functioning within the disease state and/or cancer-related conditions, MOA of 
olaratumab or doxorubicin, and/or research methods or in validating diagnostic tools or assay(s) 
related to cancer.  The primary analysis of these tumor tissue samples will be focused on the 
assessment of expression level change of PDGFRα, PDGFRβ, and canonical ligands (PDGF A, 
B, C, and D) pre- and post-olaratumab monotherapy treatment. The relationship of baseline 
expression and expression level changes from baseline of these markers will also be evaluated. 
In addition, as a part of exploratory analysis mutation profiling, gene expression, sequencing 
and/or IHC may be performed on these tissue samples to evaluate changes in immune cell 
infiltration, activation, modulation, microenvironment and changes in stromal and tumor biology 
in response to study treatment.  This may include evaluation of biomarkers related to, but not 
limited to, PD1 ligand and tumor infiltrating lymphocytes on tumor and stroma cells.
The samples will be coded with the patient number and stored for up to a maximum 15 years 
after the last patient visit for the study at a facility selected by the sponsor.  The samples and any 
data generated from them can only be linked back to the patient by investigator site personnel.  
The duration allows the sponsor to respond to regulatory requests related to the study drug.  

I5B-MC-JGDM(c) Phase 1 Oncology Protocol

Samples will be destroyed according to a process consistent with local regulation.
8.2.3.3.
Imaging Studies
A pre- and post-olaratumab monotherapy positron emission tomography (PET) scan will be 
collected for exploratory analyses at times specified in Attachment 1.  Positron emission 
tomography scan analyses measure tumor metabolic activity.  Associations between PET scan 
findings, tissue biomarkers, and CTCs will be investigated in this study.  
8.2.4. Samples for Pharmacogenetics
There is growing evidence that genetic variation may impact a patient’s response to therapy.  
Variable response to therapy may be due to genetic determinants that impact drug absorption, 
distribution, metabolism, and excretion, the mechanism of action of the drug, the disease 
etiology and/or the molecular subtype of the disease being treated.  Therefore, where local 
regulations and ERBs allow, a blood sample will be collected for pharmacogenetic analysis
(Attachment 1).  
In the event of an unexpected AE or the observation of unusual response, the pharmacogenetic 
biomarker samples may be genotyped and analysis may be performed to evaluate a genetic 
association with response to olaratumab and/or doxorubicin.  These investigations may be 
limited to a focused candidate gene study or, if appropriate, genome-wide analysis may be 
performed to identify regions of the genome associated with the variability observed in drug 
response.  The pharmacogenetic biomarker samples will only be used for investigations related 
to disease and drug or class of drugs under study in the context of this clinical program.  They 
will not be used for broad exploratory unspecified disease or population genetic analysis.
The samples will be coded with the patient number and stored for up to a maximum 15 years 
after the last patient visit for the study at a facility selected by the sponsor.  The samples and any 
data generated from them can only be linked back to the patient by investigator site personnel.  
The duration allows the sponsor to respond to regulatory requests related to the study drug.
Samples will be destroyed according to a process consistent with local regulation.
8.2.5. Samples for Immunogenicity Research
Blood samples for IG testing will be collected to determine antibody production against 
olaratumab. Refer to Attachment 4 for details. Immunogenicity will be assessed by a validated 
assay designed to detect anti-drug antibodies in the presence of olaratumab.  Antibodies may be 
further characterized and/or evaluated for their ability to neutralize the activity of olaratumab.
Samples may be stored for a maximum of 15 years following last patient visit for the trial at a 
facility selected by the sponsor to enable further analysis of immune responses to olaratumab.  
The duration allows the sponsor to respond to regulatory requests related to olaratumab.
8.3.
Efficacy Evaluations
A secondary objective of the study is to document any antitumor activity.  Refer to Attachment 1
for details regarding the timing of specific efficacy measures.  

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 55
LY3012207
Tumor assessments will be performed for each patient at the times shown in Attachment 1 until 
documented progression for patients with CR, PR, or SD, and/or for patients who have 
discontinued study treatment due to toxicity or reasons other than PD.  Imaging requirements 
include computed tomography (CT) scan or magnetic resonance imaging (MRI) of chest, 
abdomen, and pelvis and other areas, as clinically indicated.  
Computed tomography scans, including spiral CT, are the preferred methods of measurement.
The exploratory PET Scan performed pre and post Cycle 1 will not be used to determine 
efficacy.
The CT portion of a PET-CT scan may be used as a method of response assessment if the site 
can document that the CT is of identical diagnostic quality to a diagnostic CT (with IV and oral 
contrast).  A PET scan alone or as part of a PET-CT may be performed for additional analyses,
but cannot be used to assess response according to RECIST.
The method of tumor assessment used at baseline must be used consistently throughout the 
study.  Patients will be evaluated for response according to RECIST v1.1 guidelines (Eisenhauer 
et al. 2009), as outlined in Attachment 8.
8.4.
Procedure/Sampling Compliance
Every attempt will be made to enroll patients who have the ability to understand and comply 
with instructions.  Noncompliant patients may be discontinued from the study.
The collection times of safety assessments, PK samples, and efficacy measurements are given as 
targets to be achieved within reasonable limits.  The scheduled time points may be subject to 
minor alterations; however, the actual collection time must be correctly recorded on the eCRF.
The scheduled collection times may be modified by the sponsor based on analysis of the safety 
and PK information obtained during the study.  Any major modifications that might affect the 
conduct of the study, patient safety, and/or data integrity will be detailed in a protocol 
amendment.

records in the patient files as original source documents for the study.  If requested, the 
investigator will provide the sponsor, applicable regulatory agencies, and applicable ERBs/
institutional review boards (IRBs) with direct access to the original source documents.
9.2.
Data Capture Systems
9.2.1. Case Report Form
An electronic data capture system will be used in this study.  The site maintains a separate source 
for the data entered by the site into the sponsor-provided electronic data capture system.
Case report form data will be encoded and stored in a clinical trial database.
For data handled by a data management third-party organization (TPO), CRF data and some or 
all data that are related will be managed and stored electronically in the TPO system.  
Subsequent to the final database lock, validated data will be transferred to the Lilly data 
warehouse, using standard Lilly file transfer processes.
For data handled by the sponsor internally, CRF data and some or all data that are related will be 
managed by the sponsor and stored electronically in the sponsor’s system.

I5B-MC-JGDM(c) Phase 1 Oncology Protocol

Data Analyses
10.1. General Considerations
Statistical analysis of this study will be the responsibility of Lilly.
The analyses for this study will mostly be descriptive. For continuous variables, summary 
statistics will include the number of patients, mean, median, standard deviation, minimum and 
maximum.  Categorical endpoints will be summarized using the number of patients, frequency,
and percentages. For time-to-event endpoints, the Kaplan-Meier curves (Kaplan and Meier 
1958) will be estimated, and quartiles and rates at various time points together with the 95% CI 
will be provided. Missing data will not be imputed.
The interpretation of the study results will be the responsibility of the investigator with the Lilly
CRP, pharmacokineticist, and statistician.  The CRP and statistician will also be responsible for 
the appropriate conduct of an internal review for both the final study report and any study-related 
material to be authorized by Lilly for publication.
This study will have 2 database locks. The first database lock will occur when the pre- and 
post-olaratumab monotherapy tissue biopsies and the predose C1D1 and predose C2D1 whole 
blood samples have been collected for all 35 evaluable patients. The main purpose of this 
database lock is to assess biomarker expression level changes pre- and post-olaratumab 
monotherapy. The safety of olaratumab will also be evaluated at this database lock. The second 
database lock will occur at the end of the study when all patients have either completed or 
discontinued from the study and the 30-day short-term follow-up period has been completed.  In 
the second database lock, all of the study objectives will be evaluated.  There will be an interim 
analysis to look at the biomarker data once approximately half of the evaluable patients complete 
the second biopsy and the predose C2D1 whole blood draw.
10.1.1. Determination of Sample Size
To investigate the primary objective, approximately 35 evaluable patients have to have 
completed the pre-treatment tissue biopsy, the predose C1D1 whole blood draw, 1 cycle of 
olaratumab monotherapy, the post-olaratumab monotherapy biopsy, and the predose C2D1 
whole blood draw.
If the patient is noncompliant during olaratumab monotherapy (Cycle 1) and does not undergo 
the pre-treatment tissue biopsy, the post-olaratumab monotherapy biopsy, or the predose C1D1 
and predose C2D1 whole blood draw, he or she will be considered nonevaluable and may be 
replaced.
It is hypothesized that 49% (17 out of 35) or more patients will have a reduction of at least 30% 
in PDGFRα level change in tissue from baseline to post-olaratumab monotherapy. The sample 
size of 35 patients provides a 95% CI that the hit rate (proportion of patients with at least 30% 
reduction in PDGFRα level change from baseline) will be between 31% and 66%, which 
excludes a 30% or lower hit rate.  

I5B-MC-JGDM(c) Phase 1 Oncology Protocol

LY3012207
10.1.2. Analysis Populations
Efficacy analysis: the efficacy analysis will be performed on the intent-to-treat (ITT) population,
which includes all enrolled patients. The ITT population will be included in overall patient 
listings, in summary tables of patient demographics and disease characteristics, in the list of 
treatment discontinuation after enrollment, and in the analysis of efficacy.
Safety analysis:  all enrolled patients who receive any quantity of IP, regardless of their 
eligibility for the study, will be included in the safety analysis.  Safety evaluation will be 
performed based on the actual therapy a patient has received.
Biomarker analysis: the biomarker evaluable 1 (BE1) population will include all ITT patients 
with evaluable samples at both baseline and post-olaratumab monotherapy.  The BE1 population 
will be used in the biomarker analyses for the primary objective and exploratory objectives. The 
biomarker evaluable 2 (BE2) population will include all ITT population with evaluable samples 
at both baseline and post-combination (olaratumab plus doxorubicin) therapy, and will be used in 
the biomarker analyses for the exploratory objectives.
10.2. Patient Disposition
All patient discontinuations will be documented, and the extent of each patient’s participation in 
the study will be reported.  If known, a reason for their discontinuation will be given.
10.3. Patient Characteristics
Patient characteristics will include a summary of the following:

Patient demographics including age, sex, screening height and weight, and screening 
body mass index will be reported

Baseline disease characteristics

Historical diagnoses

Pre-existing conditions

Prior disease-related therapies 

Concomitant medications

Tissue histology grouped as leiomyosarcoma (LMS) or non-LMS.
Other patient characteristics will be summarized as deemed appropriate.
10.4. Safety Analyses
All patients who receive at least 1 dose of study drug will be evaluated for safety and toxicity.
The safety and tolerability of study drug is determined by reported AEs, physical examinations, 
laboratory tests, ECGs, dose adjustments, and results from ECHO/MUGA scans. 
All patients will be assessed regularly for potential occurrence of AEs from the time that the 
patient provides informed consent until 30 days after the last dose of study therapy.  Adverse 
events will be summarized by MedDRA System Organ Class and preferred term, classified from 
verbatim terms.  The incidence and percentage of patients with at least 1 occurrence of a 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 60
LY3012207
preferred term will be included, according to the most severe NCI-CTCAE Version 4.0 grade.  
The number of AEs reported per MedDRA preferred term will also be summarized.  Causality 
(relationship to study drug) will be summarized separately.  Duration of AE will be determined 
and included in listings along with action taken and outcome.
Laboratory results will be classified according to NCI-CTCAE Version 4.0.  Incidence of 
laboratory abnormalities will be summarized; laboratory results not corresponding to an NCI-
CTCAE Version 4.0 term will not be graded.  Laboratory toxicity shifts from baseline to worst 
grade will also be provided.
The results from physical examination and vital sign measurement will be tabulated.  Descriptive 
statistics will be provided as appropriate.  Electrocardiogram and ECHO/MUGA evaluation will 
be listed.
10.5. Biomarker Analyses
Primary analysis:  
All patients in the BE1 population will be evaluated for:

CTC enumeration in whole blood  

PDGFRα, PDGFRβ, and canonical ligand (PDGF-A, B, C, and D) expression 
in tumor tissue.  
The percent change from baseline for post-olaratumab monotherapy in biomarker expressions 
will be provided for each patient and summarized for all qualified patients.  Summary of number 
and frequency of patients with at least 30% reduction in change from baseline PDGFRα 
expression will also be provided.  For patients with an observed value of 0 for baseline 
expression or both baseline and post-olaratumab monotherapy expressions, a value of 0.1 will 
be used. 
10.6. Efficacy
The following secondary efficacy endpoints will be measured:
Progression-free survival (PFS): is defined as the time from enrollment until the first 
radiographic documentation of objective progression as defined by RECIST (v1.1) (Attachment 
8), or death from any cause. Patients who die without a reported prior progression will be 
considered to have progressed on the day of their death. Patients who did not progress or who 
are lost to follow-up will be censored at the day of their last radiographic tumor assessment.  If 
no baseline or postbaseline radiologic assessment is available, the patient will be censored at the 
date of enrollment.  If death or PD occurs after 2 or more consecutive missing radiographic 
visits, censoring will occur at the date of the last radiographic visit prior to the missed visits. The 
use of a new anticancer therapy or the performance of a surgical resection prior to the occurrence 
of PD will result in censoring at the date of last radiographic assessment prior to initiation of new 
therapy or surgical resection.

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 61
LY3012207
3-month PFS:  estimated as the total number of patients who did not progress 3 months after 
enrollment divided by the total number of patients.
Overall response rate (ORR): estimated as the total number of CRs, complete responses 
unconfirmed (CRus), and PRs divided by the total number of patients.  
Disease control rate (DCR): is computed as the total number of patients with the best overall 
response of CR, CRu, PR, or SD divided by the total number of patients.  
Rate of Resectability:  is defined as the total number of patients who are resectable (see 
definition of resectability in Section 4) divided by the total number of patients.
10.7. Pharmacokinetic Analyses
Pharmacokinetic parameter estimates for olaratumab will be calculated by standard 
noncompartmental methods of analysis in patients who have received at least 1 dose of 
olaratumab and have had samples collected.  The primary parameters for analysis will be 
maximum plasma concentration (Cmax), minimum plasma concentration (Cmin), area under the 
plasma concentration-time curve from time zero to the last measurable plasma concentration 
(AUC[0-tlast]), and area under the plasma concentration-time curve from time zero to infinity
(AUC[0-∞]) of olaratumab, where appropriate.  Other noncompartmental parameters, such as
half-life (t1/2), clearance (CL), and volume of distribution (Vd), may be reported.
Additional exploratory analyses may be performed if warranted by data and other validated PK 
software programs (for example, NONMEM) may be used if appropriate and approved by Lilly 
global PK management.  The version of any software used for the analysis will be documented 
and the program will meet the Lilly requirements of software validation.
10.8. Interim Analyses
An interim analysis will be done to look at the biomarker data once approximately half of the 
evaluable patients complete the second tumor tissue biopsy and C2D1 whole blood draw.  The 
purpose of this interim analysis is to review the biomarker and safety data.  If this interim look at 
the biomarker data warrants any changes in the study conduct, it will be implemented in an 
appropriate manner (that is, protocol amendment). Section 10.1 describes the 2 database locks 
and the interim analysis that will occur in this study.

Attachment 8.Protocol JGDM RECIST Criteria
Response and progression will be evaluated in this study using the international criteria proposed 
by the New Response Evaluation Criteria in Solid Tumors (RECIST): Revised RECIST 
Guideline (version 1.1; Eisenhauer et al. 2009).  
Measurability of Tumor at Baseline
Tumor lesions/lymph nodes will be categorized at baseline as measurable or nonmeasurable.  
Measurable disease is defined by the presence of at least 1 measurable lesion.
Measurable 
Tumor lesions:  Measured in at least 1 dimension (longest diameter in the plane of measurement 
is to be recorded) with a minimum size of:

10 mm by computed tomography (CT) or magnetic resonance imaging (MRI) 
scan (slice thickness 5 mm) 

10 mm caliper measurement by clinical exam (non-measurable lesions if cannot 
be accurately measured with calipers)

20 mm by chest X-ray.
Malignant lymph nodes:  To be considered pathologically enlarged and measurable, a lymph 
node must be 15 mm in short axis when assessed by CT scan (CT scan thickness recommended 
to be 5 mm).
Nonmeasurable 
All other lesions, including small lesions (longest diameter <10 mm or pathological lymph nodes 
with 10 to <15 mm short axis) as well as truly nonmeasurable lesions.  Lesions considered truly 
non-measurable include:  leptomeningeal disease, ascites, pleural/pericardial effusions, 
lymphangitis cutis/pulmonis,  inflammatory breast disease, lymphangitis involvement of skin or 
lung, abdominal masses/abdominal organomegaly identified by physical exam that is not 
measureable by reproducible imaging techniques.
Special Considerations for Lesion Measurability
Bone lesions:  

Bone scan, PET scan or plain films are not considered adequate imaging 
techniques to measure bone lesions.

Lytic bone lesions or mixed lytic-blastic lesions, with identifiable soft tissue 
components, that can be evaluated by cross sectional imaging techniques such as 
CT or MRI, can be considered measurable lesions if the soft tissue component 
meets the definition of measurability.

Blastic bone lesions are non-measurable.

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 85
LY3012207
Cystic lesions:  

Simple cysts should not be considered as malignant lesions (neither measurable 
nor nonmeasurable) 

Cystic lesions thought to represent cystic metastases can be considered as 
measurable lesions, if they meet the definition of measurability.  If noncystic 
lesions are presented in the same patients, these are preferred for selection as 
target lesions.
Lesions with Prior Local Treatment:

Tumor lesions situated at a previously irradiated area, or in an area subjected 
to other loco-regional therapy, are non-measurable unless there has been 
demonstrated progression in the lesion.  
Baseline Documentation of Target and Non-Target Lesion
Target Lesions
When more than 1 measurable lesion is present at baseline, all lesions up to a maximum of 5 
lesions total (and a maximum of 2 lesions per organ) representative of all involved organs should 
be identified as target lesions and will be recorded and measured at baseline. Non-nodal Target 
lesions should be selected on the basis of their size (lesions with the longest diameter), be 
representative of all involved organs, and can be reproduced in repeated measurements..  
Measurable lymph nodes are target lesions if they meet the criteria of a short axis of 15 mm by 
CT scan.  All measurements are to be recorded in the case record form (CRF) in millimeters (or 
decimal fractions of centimeters [cm]).
Nontarget Lesions
All other lesions (or sites of disease) are identified as nontarget lesions (chosen based on their 
representativeness of involved organs and the ability to be reproduced in repeated measurements) 
and should be recorded at baseline.  Measurement of these lesions are not required but should be 
followed as ‘present,’ ‘absent,’ or in rare cases ‘unequivocal progression.’  In addition, it is 
possible to record multiple nontarget lesions involving the same organ as a single item on the 
CRF (for example, multiple liver metastases recorded as one liver lesion).
Lymph nodes with short axis 10 mm but <15 mm should be considered nontarget lesions.  
Nodes that have a short axis <10 mm are considered nonpathological and are not recorded or 
followed.
Specifications by Methods of Measurement
All measurements should be recorded in metric notation, using a ruler or calipers if clinically 
assessed.  All baseline evaluations should be performed as closely as possible to the beginning of 
treatment and never more than 4 weeks before the beginning of the treatment.
The same method of assessment and the same technique should be used to characterize each 
identified and reported lesion at baseline and during follow-up.  Imaging-based evaluation is 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 86
LY3012207
should always be done rather than clinical examination unless the lesion(s) being followed 
cannot be imaged but are assessed by clinical exam.  
An adequate volume of a suitable contrast agent should be given so that the metastases are 
demonstrated to best effect and a consistent method is used on subsequent examinations for any 
given patient.  If prior to enrollment it is known a patient is not able to undergo CT scans with IV 
contrast due to allergy or renal insufficiency, the decision as to whether a non-contrast CT or 
MRI (with or without IV contrast) should be used to evaluate the patient at baseline and follow-
up should be guided by the tumor type under investigation and the anatomic location of the 
disease.
Clinical Lesions:  Clinical lesions will only be considered measurable when they are superficial 
and 10 mm diameter as assessed using calipers (for example, skin nodules).  For the case of 
skin lesions, documentation by color photography, including a ruler to estimate the size of the 
lesion is recommended.  When lesions can be evaluated by both clinical exam and imaging, 
imaging evaluation should be undertaken since it is more objective and may be reviewed at the 
end of the study.
Chest X-ray:  Chest CT is preferred over chest X-ray when progression is an important endpoint.  
Lesions on chest X-ray may be considered measurable if they are clearly defined and surrounded 
by aerated lung.
CT and MRI:  CT scan is the best currently available and reproducible method to measure lesions 
selected for response assessment.  Measurability of lesions on CT scan is based on the 
assumption that CT slice thickness is 5 mm.  When CT scan have slice thickness >5 mm, the 
minimum size for a measurable lesion should be twice the slice thickness.  MRI is also 
acceptable in certain situations (for example, for body scans).  If there is concern about radiation 
exposure at CT, MRI may be used instead of CT in selected instances.  
Ultrasound:  Ultrasound should not be used to measure lesion size.  Ultrasound examinations 
cannot be reproduced in their entirety for independent review at a later date and, because they are 
operator dependent, it cannot be guaranteed that the same technique and measurements will be 
taken from one assessment to the next.  If new lesions are identified by ultrasound in the course 
of the study, confirmation by CT or MRI is advised.
Endoscopy, Laparoscopy:  The utilization of these techniques for objective tumor evaluation is 
not advised.  However, such techniques can be useful to confirm complete pathological response 
when biopsies are obtained or to determine relapse in trials where recurrence following complete 
response or surgical resection is an endpoint.
Tumor Markers:  Tumor markers alone cannot be used to assess tumor response.  If markers are 
initially above the upper normal limit, they must normalize for a patient to be considered in 
complete response (CR).  Specific guidelines for both prostate-specific antigen (PSA) response 
(in recurrent prostate cancer) and CA-125 response (in recurrent ovarian cancer) have been 
published.  

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 87
LY3012207
Cytology, Histology:  These techniques can be used to differentiate between partial responses 
(PR) and complete response (CR) in rare cases if required by protocol (for example, residual 
lesions in tumor types such as germ cell tumors, where known residual benign tumors can 
remain).  When effusions are known to be a potential adverse effect of treatment (for example, 
with certain taxane compounds or angiogenesis inhibitors), the cytological confirmation of the 
neoplastic origin of any effusion that appears or worsens during treatment can be considered if 
the measurable tumor has met criteria for response or stable disease (SD) in order to differentiate 
between response (or SD) and progressive disease (PD). 
Pet Scan (FDG-PET, PET CT):  PET is not recommended for lesion assessment. If a new lesion 
is found by PET, another assessment must be done by CT, unless the PET CT is of diagnostic 
quality.  If CT is done to confirm the results of the earlier PET scan, the date of progression must 
be reported as the earlier date of the PET scan. 
Bone Scan:  If lesions measured by bone scan are reported at baseline, it is necessary to repeat 
the bone scan when trying to identify a complete response (CR) or partial response (PR) in target 
disease or when progression in bone is suspected. 
Response Criteria
Evaluation of Target Lesions 
Complete Response (CR):  Disappearance of all target lesions.  Any pathological lymph nodes 
(whether target or non-target) must have reduction in short axis to <10 mm.  Tumor marker 
results must have normalized.
Partial Response (PR):  At least a 30% decrease in the sum of diameter of target lesions, taking 
as reference the baseline sum diameters.
Progressive Disease (PD):  At least a 20% increase in the sum of the diameters of target lesions, 
taking as reference the smallest sum on study (including the baseline sum if that is the smallest).  
In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase 
of at least 5 mm.  The appearance of one or more new lesions is also considered progression.
For equivocal findings of progression (for example, very small and uncertain new lesions; cystic 
changes or necrosis in existing lesions), treatment may continue until the next scheduled 
assessment.  If at the next scheduled assessment, progression is confirmed, the date of 
progression should be the earlier date when progression was suspected.
Stable Disease (SD):  Neither sufficient shrinkage to qualify for PR nor sufficient increase to 
qualify for PD, taking as reference the smallest sum diameters while on study.
Not Evaluable:  When an incomplete radiologic assessment of target lesions is performed or 
there is a change in the method of measurement from baseline that impacts the ability to make a 
reliable evaluation of response. 
Evaluation of Nontarget Lesions
Complete Response:  Disappearance of all nontarget lesions and normalization of tumor marker 
level.  All lymph nodes must be non-pathological or normal in size (<10mm short axis).

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 88
LY3012207
Non-CR/ non-PD:  Persistence of 1 or more nontarget lesions and/or maintenance of tumor 
marker level above the normal limits.
Progressive Disease:  Unequivocal progression of existing nontarget lesions.  The appearance of 
1 or more new lesions is also considered progression.
Not Evaluable: When a change in method of measurement from baseline occurs and impacts the 
ability to make a reliable evaluation of response.
Evaluation of Best Overall Response
The best overall response is the best response recorded from the start of the study treatment until 
the earliest of objective progression or start of new anticancer therapy, taking into account any 
requirement for confirmation.  The patient’s best overall response assignment will depend on the 
findings of both target and nontarget disease and will also take into consideration the appearance 
of new lesions.  The Best Overall Response will be calculated via an algorithm using the 
assessment responses provided by the investigator over the course of the trial.  
Time Point Response
It is assumed that at each protocol-specified time point, a response assessment occurs.  (When no 
imaging/measurement is done at all at a particular time point, the patient is not evaluable (NE) at 
that time point.)  Table 1 provides a summary of the overall response status calculation at each 
time point for patients who have measurable disease at baseline.

a
non-CR/non-PD is preferred over SD for nontarget disease. 
Frequency of Tumor Re-Evaluation
A baseline tumor evaluation must be performed within 4 weeks before patient begins study 
treatment.  Frequency of tumor re-evaluation while on and adapted to treatment should be 
protocol-specific and adapted to the type and schedule of treatment.  In the context of Phase 2 
studies where the beneficial effect therapy is not known, follow-up every 6-8 weeks is 
reasonable.  Normally, all target and non-target sites are evaluated at each assessment using the 
same method.  However, bone scans may need to be repeated only when CR is identified in 
target disease or when progression in bone is suspected.  
Confirmatory Measurement/Duration of Response
Confirmation:
The main goal of confirmation of objective response in clinical trials is to avoid overestimating 
the response rate observed.  The confirmation of response is particularly important in 
nonrandomized trials where response (CR/PR) is the primary end point.  In this setting, to be 
assigned a status of PR/CR, changes in tumor measurements must be confirmed by repeat 
assessments that should be performed no less than 4 weeks after the criteria for response are first 
met.  To confirm a response of CR, a full assessment of all target and nontarget lesions that were 
present at baseline must occur, including those measured by bone scan.  To confirm a PR or SD, 
a full assessment of target lesions that were present at baseline must occur; assessment of 
nontargets is not required.  
However, in randomized trial (Phase 2 or 3) or studies where SD or progression is the primary 
endpoints, confirmation of response is not required.  But, elimination of the requirement may 
increase the importance of central review to protect against bias, in particular of studies which 
are not blinded.
In the case of SD, follow-up measurements must have met the SD criteria at least once after start 
of treatment at a minimum interval not less than 6 weeks measured from first dose.
Duration of Overall Response
The duration of overall response is measured from the time measurement criteria are first met for 
CR or PR (whichever is first recorded) until the first date that disease is recurrent or objective 
progression is observed (taking as reference for PD the smallest measurements recorded on 
study).

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 90
LY3012207
The duration of overall CR is measured from the time measurement criteria are first met for CR 
until the first date that recurrent disease is objectively documented.
Duration of Stable Disease
Stable disease is measured from the start of the treatment (in randomized trials, from date of 
randomization) until the criteria for objective progression are met, taking as reference the 
smallest sum on study (if the baseline sum is the smallest, that is the reference for calculation of 
PD).  
Independent Review of Response and Progression
When objective response (CR + PR) is the primary end point, and when key drug development 
decisions are based on the observation of a minimum number of responders, it is recommended 
that all claimed responses be reviewed by an expert(s) independent of the study.  If the study is a 
randomized trial, ideally reviewers should be blinded to treatment assignment.

MC-JGDM(c) Summary: A Phase 1b Trial to Assess the 
Modulation of Biological Markers in Patients with 
Potentially Resectable Soft Tissue Sarcoma Treated with 
Olaratumab Monotherapy Followed by Olaratumab plus 
Doxorubicin Combination Therapy
Overview
Protocol I5B-MC-JGDM, A Phase 1b Trial to Assess the Modulation of Biological Markers in 
Patients with Potentially Resectable Soft Tissue Sarcoma Treated with Olaratumab Monotherapy 
Followed by Olaratumab plus Doxorubicin Combination Therapy, has been amended.  The new 
protocol is indicated by Amendment (c) and will be used to conduct the study in place of any 
preceding version of the protocol.
The overall changes and rationale for the changes made to this protocol are as follows:

The term QTcF was defined in the abbreviations and definition section.

Fridericia’s QT correction formula was added for patients with bundle branch block.

Exclusion criteria 22 was updated by removing language related to the patient’s 
ability to adhere to the protocol and to indicate the exclusion criteria refers to a 
concomitant systemic disorder the patient is currently experiencing.

Exclusion criteria 23 was corrected.

Section 7.1.2. was updated to reference the Pharmacy Manual rather than text from 
the manual. 

A clarification was made in Section 7.2.3.1 for dose delays that collection of PK 
samples should be derived from time the actual olaratumab dose was given vs when 
dose was originally expected.

Section 8.2.3.2. was corrected for tumor tissue from any posttherapy surgical 
resection to be optional rather than required.

Section 10.1. and 10.1.1. was clarified to add the C1D1 predose blood draw to the 
definition of an evaluable patient.

A clarification was made in the schedule of events to both treatment and baseline PET 
scan to move them to the appropriate place in the schedule.

A change was made in the timing of pre-Dose PK sample in order to allow for 
samples to be collected before pre-medications are administered.

are allowed if they are within the intended or expected range for their 
therapeutic use.  Patients must have no history of active bleeding 
(defined as within 14 days of first dose of study drug) or pathological 
condition that carries a high risk of bleeding (for example, tumor 
involving major vessels or known esophageal varices).

6.2 Summary of Study Design

Long-term follow-up:  begins the day after short-term follow-up is 
completed.
Follow-up for progression - Patients who discontinue study 
treatment, or have completed 6 cycles of combination therapy, and 
have not progressed and have not initiated a new systemic 
treatment for their disease will be assessed for progression by 
imaging studies every 6 weeks (±<7 days) until PD.  Patients who 
have had surgical resection will not be followed for subsequent 
progression by imaging studies.
7.1.2. Olaratumab
Please refer to the Pharmacy Manual for information on preparing the olaratumab dosing 
solution for infusion.
Prepared Olaratumab Dosing Solution for Infusion:  Chemical and physical in-use stability for 
the prepared olaratumab dosing solution has been demonstrated for up to 24 hours below 25ºC 
(77ºF) in the concentration range of 1.2 mg/mL to 6.4 mg/mL.  It is recommended that the 
prepared dosing solution be used immediately to minimize the risk of microbial contamination.  
If not used immediately, the prepared olaratumab dosing solution must be stored under 
refrigeration at 2ºC-8ºC (36ºF-46ºF) for a duration not to exceed 24 hours.  If the prepared 
solution is held at room temperature (below 25ºC [77ºF]), it must be used within 4 hours.  Do not 
freeze and/or shake prepared olaratumab dosing solution for infusion.
Aseptic technique is to be used when preparing and handling olaratumab.  Patients are to receive 
a loading dose of 20 mg/kg on Days 1 and 8 in the monotherapy lead-in cycle, and again on Days 
1 and 8 in the first cycle of combination therapy (Cycle 2), followed by 15 mg/kg of olaratumab 
on Days 1 and 8 of each subsequent 21-day treatment cycle (Cycle 3-Cycle 7), administered as 
an IV infusion.  On the days that both olaratumab and doxorubicin are administered, olaratumab 

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 96
LY3012207
will be administered prior to doxorubicin.  The dose of olaratumab is dependent upon the 
patient’s body weight (Section 7.3.1).  Actual body weight will be used for dose calculation.  
Subsequent doses of olaratumab must be recalculated if there is a ≥10% change (increase or 
decrease) in body weight; subsequent doses may be recalculated if there is a <10% change in 
body weight from prior dose and considered clinically relevant by the treating investigator.
Olaratumab is compatible with commonly used infusion containers.  Refer to the IB or pharmacy 
manual for detailed information.  Olaratumab concentration of below 1.2 mg/ml in prepared dose 
should be avoided due to dilution of excipients, which are important in maintaining stability.
The dose of olaratumab will be aseptically withdrawn from the vial and transferred to a sterile 
infusion bag or an evacuated glass container.  To prepare the dose, a sufficient quantity of sterile 
normal saline (0.9% weight/volume) solution should be added (or removed in the case of a 
prefilled container such as AVIVA) to make the total volume 250 mL.  The container should be 
gently inverted to ensure adequate mixing.  In some cases, the volume of infusion solution 
required may exceed the 250-mL scenario described here to keep the infusion solution 
concentration within the desired range stated above.  This situation may be more likely with the 
required loading dose of 20 mg/kg given in Cycle 1, but may also apply to any subsequent cycle 
depending on the patient’s body weight.  In case of dose volumes >250 mL, an empty 500-mL 
container of acceptable material of construction can be used without addition of any normal 
saline.  A pre-filled container (filled with 0.9% normal saline) of >250 mL size can be used as 
long as the material of construction is acceptable and the concentration of olaratumab in prepared 
dose remains within 1.2 mg/mL to 6.4 mg/mL.
The dose should be infused over approximately 60 minutes.  The infusion rate should not exceed 
25 mg/min.  Infusion durations longer than 60 minutes are permitted in specific circumstances 
(that is, for patients with higher body weight for whom the upper limit of infusion rate is limited 
or in the setting of prior olaratumab Grade 1-2 infusion-related reaction [IRR]); the infusion 
duration must always be accurately recorded.
The infusion set must be flushed immediately postinfusion of dose with sterile normal saline to 
ensure complete delivery of the calculated dose.

a
Premedicate all patients with the following (or equivalent) medications:  a histamine H1 antagonist (for example, 
diphenhydramine) and dexamethasone intravenously 30–60 minutes prior to the olaratumab doses on Days 1 and 
8 of Cycle 1.  For subsequent cycles, premedicate all patients with a histamine H1 antagonist (for example, 
diphenhydramine) intravenously 30-60 minutes prior to each dose of olaratumab.  Additional premedication may 
be provided at the investigator’s discretion.  Premedication must be provided in the setting of a prior Grade 1-2 
IRR, as detailed in Section 7.2.2 and Section 7.2.3.1.1.1.  All premedication administered must be adequately 
documented in the eCRF.
b
A 1-hour (+5 minutes) Observation Period is required after the administration of the initial 2 cycles of 
olaratumab.  During the Observation Period, collect vital signs 3 times:  1) within 15 minutes (+5 minutes) prior 
to olaratumab infusion, 2) within 1 hour (+5 minutes) after completion of the olaratumab infusion, and 3) within 
1 hour (+5 minutes) after completion of the doxorubicin infusion.  If no evidence of an IRR manifests during the 
initial 2 cycles of olaratumab, then no observation period is required for subsequent treatment cycles.  In the 
event an IRR occurs thereafter, then the 1-hour Observation Period should be reinstituted; see Section 7.1.2.  
Thereafter (Cycles 3+), obtain vital signs 2 times:  1) within 15 minutes (+5 minutes) prior to olaratumab 
infusion and 2) within 1 hour (+5 minutes) after completion of the doxorubicin infusion.
c
Administer doxorubicin according to institutional guidelines and/or clinical practice as an IV injection or as an 
infusion in less thanwithin 60 minutes.  Decrease the rate of doxorubicin administration if erythematous streaking 
along the vein proximal to the site of infusion or facial flushing occurs.  Infusion or injection start and end times 
will need to be recorded.  Starting with Cycle 2, dexrazoxane may be administered at a 10:1 ratio 
(dexrazoxane:doxorubicin) at the investigator’s discretion according to instructions provided in the pharmacy 
manual for this study, beginning within 30 minutes prior to the doxorubicin infusion for prevention of 
cardiotoxicity.  It is recommended that all patients receiving 5 or more cycles of doxorubicin receive 
dexrazoxane.
7.2.3.1. Dose Delays, Modifications, and Discontinuations
To begin dosing at each cycle, the following criteria must be fulfilled:After treatment has been 
initiated, in order to start the next cycle the following criteria must be fulfilled:

ANC ≥1.0 × 103/L (1000/L; ≥1.0 × 109/L)

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 98
LY3012207
Note that in order to administer single-agent olaratumab on Day 8, ANC must 
be 750/L; 0.75 × 109/L.  If the ANC is 750/L, the Day 8 administration 
of olaratumab may be delayed for a maximum of 7 days.  If the ANC level has 
not increased to 750/L within 7 days, then the Day 8 olaratumab dose in 
that cycle should be skipped and dosing resumed on Day 1 of the following 
cycle if criteria for dosing are met.  If all dosing criteria are met, a delay or 
omission of the Day 8 olaratumab dose should not result in a delay of the 
Day 1 olaratumab dose of the following cycle. 

Platelets ≥100 × 103/L (100,000/L; ≥100 × 109/L)

Hemoglobin ≥98 g/dL

Creatinine clearance ≥45 mL/min (refer to Attachment 7 for the 
Cockcroft-Gault formula)

Proteinuria ≤1000 mg in 24 hours (if routine urinalysis indicates 
≥2+ proteinuria) (to be performed every other cycle)

Total bilirubin below ULN

AST and ALT ≤3.0 x ULN, or ≤5 x ULN if the transaminase elevation is due 
to liver metastases

Olaratumab-related AEs that are NCI-CTCAE Version 4.0 Grade <2 or 
equivalent severity to baseline
Delays:
In general, dose delays of 1 study drug (olaratumab or doxorubicin) due to toxicity guidances 
outlined in Sections 7.2.3.1.1 and 7.2.3.1.2 will not necessitate delays of the other study drug.
Treatment may be delayed for up to 21 days (1 equivalent cycle) to allow a patient sufficient 
time for recovery from study drug-related toxicity.  If a patient does not recover from the toxicity 
within 42 days (2 equivalent cycles) from Day 1 of the previous treatment cycle, then the patient 
must be discontinued from study therapy.
Any procedure or sample collection whose timing is related to olaratumab dosing is to be 
completed according to when the olaratumab dose was actually administered, not when that dose 
was expected to occur.   Samples whose adjusted timing would fall outside of the treatment cycle 
duration due to dose delay may be omitted.]
7.5 Concomitant Therapy
Bisophosphonate osteoclast inhibitors (for example, zoledronic acid or pamidronate) for 
treatment of bone metastases will be permitted while patients are on study treatment.  However, 
the osteoclast inhibitor denosumab is a monoclonal antibody and could confound safety analysis 
in the study if the patient experiences a hypersensitivity reaction to denosumab.  Therefore, 
concomitant use of denosumab will not be permitted.
7.6.1. Evaluable Patients

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 99
LY3012207
If the patient is noncompliant during olaratumab monotherapy (Cycle 1) and does not undergo 
the post-olaratumab monotherapy biopsy or the C1D1 pre-dose and C2D1 predose whole blood 
sample collection due to reasons other than drug-related toxicity, he or she will be considered 
nonevaluable for the primary objective.  These patients may be replaced to ensure that 35 
patients complete the pre-treatment tissue biopsy, the C1D1 pre-dose whole blood sample 
collection, 1 cycle of olaratumab monotherapy, and the post-olaratumab monotherapy biopsy, 
and the associated C2D1 predose whole blood sample collection.
8.1.2.2.3. Follow-Up Visit
All AEs and SAEs, regardless of relatedness to study drugs or protocol procedures, occurring 
during the follow-up visit (Visit 801) must be reported to Lilly or its designee. The follow-up 
visit begins the day after the patient and the investigator agree that the patient will no longer 
continue study treatment starts following the last dose of study drug.  At the end of the follow-up 
visit, the patient will be required to have specific safety assessments (Attachment 1).  The timing 
of these safety assessments is 30 ± 7 days after the last dose of study drug.
8.1.3.1. Electrocardiograms
Table JGDM.6 provides Bazett’s QT  heart rate correction formula. Table JGDM.8.3 provides 
Fridericia’s QT correction formula for patients with bundle branch block.

corresponding points on 2 consecutive R waves on ECG.
8.1.3.2. Echocardiograms/MUGA Scans
An ECHO or MUGA scan is required within 28 days prior to enrollment for all patients.  
Thereafter, ECHO or MUGA scans, whichever technique was used initially (as described in 
Section 7.2.3.1.2.2), must be performed at the end of Cycles 5 and 7, and when clinically 
indicated.  For patients with LVEF <50% or other cardiac dysfunction, perform more frequently, 
if clinically indicated.  After Cycle 7 (for patients with resting LVEF >≥50%), an ECHO or 
MUGA scan should be obtained at the 30-day follow-up visit (refer to the Study Schedule 
[Attachment 1]).  
Patients who stop doxorubicin prior to Cycle 7 (with resting LVEF >≥50%) will undergo cardiac 
monitoring assessment at the 30-day follow-up visit (refer to the Study Schedule [Attachment 1]) 
with whichever technique (ECHO or MUGA scan) was used initially (as described in Section
7.2.3.1.2.2).
8.2.3.2. Tumor Tissue
Collection of the following tumor tissue samples is mandatory for all patients:

newly obtained biopsy specimens taken from the primary tumor lesion pre- and post-
olaratumab monotherapy treatment will be collected.  The pretreatment tissue biopsy is to 
be performed within the screening period.  The posttreatment tissue biopsy is to be 
performed after completion of the lead-in cycle of olaratumab monotherapy and prior to 
the initiation of combination therapy (Cycle 2).  Refer to Attachment 1 for additional 
details.  If clinically feasible, the biopsies should be taken from the same primary tumor 
lesion. 

tumor tissue from any posttherapy surgical resection should also be collected and 
provided.
Collection of the following tumor tissue samples is optional for all patients:

biopsy specimen collected at the end of the patient’s study treatment.  Refer to 
Attachment 1 for additional details.  If clinically feasible, this biopsy should be taken 
from the same primary tumor lesion.

tumor  tissue from any posttherapy surgical resection may also be collected and provided.  
While this specimen is optional, it is expected this sample will be sent for analysis.
8.3 Efficacy Evaluations
Computed tomography scans, including spiral CT, are the preferred methods of measurement.
The exploratory PET Scan performed pre and post cycle 1 will not be used to determine efficacy.
10.1 General Considerations

I5B-MC-JGDM(c) Phase 1 Oncology Protocol
Page 101
LY3012207
This study will have 2 database locks.  The first database lock will occur when the pre- and post-
olaratumab monotherapy tissue biopsies and the pre-dose C1D1 and the predose C2D1 whole 
blood sample have been collected for all 35 evaluable patients.  The main purpose of this 
database lock is to assess biomarker expression level changes pre- and post-olaratumab 
monotherapy.  The safety of olaratumab will also be evaluated at this database lock.  The second 
database lock will occur at the end of the study when all patients have either completed or 
discontinued from the study and the 30-day short-term follow-up period has been completed.  In 
the second database lock, all of the study objectives will be evaluated.  There will be an interim 
analysis to look at the biomarker data once approximately half of the evaluable patients complete 
the second biopsy and the predose C2D1 whole blood draw.
10.1.1. Determination of Sample Size
To investigate the primary objective, approximately 35 evaluable patients have to have 
completed the pre-treatment tissue biopsy, the predose C1D1 whole blood draw, 1 cycle of 
olaratumab monotherapy, the post-olaratumab monotherapy biopsy, and the predose C2D1 
whole blood draw. 
If the patient is noncompliant during olaratumab monotherapy (Cycle 1) and does not undergo 
the pre-treatment tissue biopsy, the post-olaratumab monotherapy biopsy, or the pre-dose C1D1 
and predose C2D1 whole blood draw, he or she will be considered nonevaluable and may be 
replaced.
10.8. Interim Analyses
An interim analysis will be done to look at the biomarker data once approximately half of the 
evaluable patients complete the second tumor tissue biopsy and C2D1 whole blood draw.  The 
purpose of this interim analysis is to review the biomarker and safety data.  If this interim look at 
the biomarker data warrants any changes in the study conduct, it will be implemented in an 
appropriate manner (that is, protocol amendment).  Section 10.1 describes the 2 database locks 
and the interim analysis that will occur in this study.
