Planned Number of Patients: Approximately 400 patients 
Study Centers: Approximately 150 study centers 
Duration of Study: Approximately 34 months with 22 months for 
enrollment and treatment and 12 months for safety follow-up.  
Clinical Phase: 3 
Objectives:  
Primary Objective: 
To compare the efficacy of a single dose of SPI-2012 with pegfilgrastim in patients with early-stage breast 
cancer receiving docetaxel and cyclophosphamide (TC), as measured by the Duration of Severe Neutropenia 
(DSN) in Cycle 1 
Key Secondary Objectives: 
 
To compare SPI-2012 with pegfilgrastim in: 
1. Time to Absolute Neutrophil Count (ANC) Recovery in Cycle 1 
2. Depth of ANC Nadir, defined as the patient’s lowest ANC in Cycle 1 
3. Incidence of Febrile Neutropenia (FN) in patients during Cycle 1 
Additional Secondary Objectives: 
 
To compare SPI-2012 with pegfilgrastim in: 
1. Duration of Severe Neutropenia in Cycles 2, 3, and 4 
2. Incidence of Neutropenic Complications, including anti-infective use and hospitalizations in 
patients during Cycle 1  
3. Incidence of FN in Cycles 2, 3, and 4 
4. Relative Dose Intensity (RDI) of TC in Cycles 1 to 4 
5. Safety 
Study Design and Treatment Plan: 
This is a Phase 3, randomized, open-label, active-controlled, multicenter study to compare the efficacy and 
safety of SPI-2012 with pegfilgrastim in breast cancer patients treated with TC chemotherapy.  
Approximately 400 patients will be enrolled and randomized in a 1:1 ratio to 2 treatment arms:  
 
Treatment Arm 1 (n= approximately200): SPI-2012 (13.2 mg/0.6 mL fixed dose SPI-2012 equivalent 
to 3.6 mg G-CSF) 
 
Treatment Arm 2 (n= approximately200): Pegfilgrastim (6 mg/0.6 mL)  
Prior to TC chemotherapy administration, patients may receive premedication according to institutional standard 
of care. Intravenous (IV) administration of TC on Day 1 of each cycle will be as follows:  
 
Docetaxel 75 mg/m2 IV infusion per institute’s standard of care 
 
Cyclophosphamide 600 mg/m2 IV infusion per Institute’s standard of care

Each cycle will be 21 days. Only 4 cycles will be evaluated for this study. After Cycle 1, patients must have 
ANC ≥1.5×109/L and platelet count ≥100×109/L to begin each of the next cycles of chemotherapy.  
The study drug (SPI-2012 or pegfilgrastim) will be administered on Day 2 of each cycle, approximately 24 to 26 
hours after the last dose of TC chemotherapy is given. Study drug (SPI-2012 or pegfilgrastim) dose 
modifications are not allowed. 
On Day 1 of each cycle, patients will receive TC chemotherapy, and safety and efficacy assessments will be 
performed as outlined in the protocol. On Day 2 of each cycle, patients will receive study drug (SPI-2012 or 
pegfilgrastim), and the specified assessments will be performed.  
Absolute neutrophil count will be monitored on Day 1 and Days 4 to 15 in Cycle 1. In Cycles 2 to 4, all patients 
must have blood samples drawn on Day 1 (prior to chemotherapy administration), on Days 4, 7, 10, and 15 
(±1 day for each collection), and at the End-of-Treatment Visit. If the participating site is notified that the ANC 
is ≤1.0×109/L at any time during Cycles 2 to 4, then daily CBCs will be required until the ANC is ≥1.5×109/L, 
after reaching nadir, but blood samples must still be drawn on Days 4, 7, 10, and 15.  
After Cycle 1, as applicable, patients who have received at least one dose of study drug will be followed for 12 
months after the last dose of study treatment for safety follow-up.  
Duration of Study: Approximately 34 months with 22 months for enrollment and treatment and 12 months for 
safety follow-up. 
The duration of the study for each patient in SPI-GCF-301 will be approximately16 months including: 
 
Screening Period: 30 days 
 
Treatment Period: 4 cycles, 21 days per cycle 
 
End-of-Treatment Visit: 35 (±5) days after last dose of study treatment 
 
Safety Follow-up Period: 12 months after the last dose of study treatment 
 
End-of-Study Visit: At the 12 Month Visit or 35 (±5) days after the date of early discontinuation

Efficacy Assessments: 
Primary Endpoint: 
 
Comparison of the Duration of Severe Neutropenia (DSN) in Cycle 1 between the SPI-2012 
Treatment Arm and the Pegfilgrastim Treatment Arm.  
DSN is defined as the number of days of severe neutropenia (ANC <0.5×109/L) from the first occurrence of an 
ANC below the threshold. The assessment of ANC will be performed on Day 1 and Days 4 to 15 in Cycle 1. The 
endpoint will be measured in all patients in an Intent-to-Treat Population (ITT Population). For patients who 
do not meet severe neutropenia criteria, the endpoint measurement will be defined as DSN=0. 
Key Secondary Endpoints: 
 
To compare SPI-2012 with pegfilgrastim in: 
1. Time to ANC Recovery in Cycle 1  
2. Depth of ANC Nadir, defined as the patient’s lowest ANC in Cycle 1 
3. Incidence of FN in patients during Cycle 1 
The analyses of the Key Secondary Endpoints will employ a hierarchical, closed testing procedure. 
Additional Secondary Endpoints: 
 
To compare SPI-2012 with pegfilgrastim in: 
1. Duration of Severe Neutropenia in Cycles 2, 3, and 4 
2. Incidence of Neutropenic Complications, including use of anti-infectives and hospitalizations, in 
patients during Cycle 1 
3. Incidences of FN in Cycles 2, 3, and 4 
4. RDI of TC in Cycles 1 to 4 
5. Safety 
Pharmacokinetic Assessments: 
All patients in the SPI-2012 treatment arm will have blood samples drawn for sparse PK sampling at 6 time 
points during the study period for PK analysis. The sampling time points will be: 
 
Cycle 1:  
 
Day 2 (1 to 4 hours after SPI-2012 administration) 
 
Day 4 (at the same time as CBC blood draw) 
 
Day 5 (at the same time as CBC blood draw) 
 
Cycle 3: 
 
Day 2 (1 to 4 hours post-dose) 
 
Day 4 (±1 day, at the same time as CBC blood draw) 
 
Day 7 (±1 day, at the same time as CBC blood draw)  
Safety Assessments: 
Safety (secondary endpoint) will be assessed by reported/elicited adverse events (AEs), laboratory assessments, 
and physical examinations. In addition, as applicable, patients who receive at least one dose of study drug will 
be followed for 12 months after the last dose of study treatment to assess long-term safety; patients who receive 
SPI-2012 will be tested for antibodies to SPI-2012, the Fc region of the SPI-2012 molecule, the PEG moiety, 
and G-CSF. Patients who receive pegfilgrastim will be tested for antibodies to SPI-2012, PEG and G-CSF. All 
sera samples positive for G-CSF-binding antibodies will be further tested for G-CSF neutralizing antibodies.  
Adverse Event and Serious Adverse Event Reporting: 
All AEs that occur from the first dose of study treatment through 35 (±5) days after the date of last study 
treatment or date of patient early discontinuation are to be recorded on the AE CRF. Additionally, as applicable,

7 
patients who receive at least one dose of study drug (SPI-2012 or pegfilgrastim) will be followed for 12 months 
after the last dose of study treatment to evaluate the long-term safety and immunogenicity of SPI-2012. All AEs 
during this time period will be recorded. From the time the study Informed Consent is signed through the first 
dose of study drug administration, only SAEs that are related to study procedures are to be recorded. 
Statistical Methods: 
For the primary efficacy analysis, the mean DSN in Cycle 1 will be compared between the SPI-2012 and 
Pegfilgrastim Treatment Arms using a bootstrap resampling method with non-inferiority hypothesis. A 
2-sided 95% confidence interval (CI) of the difference between the mean DSN of the SPI-2012 Treatment Arm 
and the mean DSN of the Pegfilgrastim Treatment Arm will be calculated using bootstrap resampling with 
treatment as the only stratification factor. The study will use a non-inferiority margin of 0.62 day for the above 
comparison.  
The non-inferiority of SPI-2012 to pegfilgrastim will be declared if the upper bound of 95% CI of the difference 
in mean DSN between the treatment arms is <0.62 days. Primary analysis for the non-inferiority hypothesis will 
be based on the ITT Population. An analysis based on the Per Protocol Population will be performed as a 
sensitivity analysis.  
For the secondary efficacy analyses, the results will each be summarized by Treatment Arm and Cycle. The two-
sided 95% CI for the difference between the treatment arms will be calculated. 
For safety analysis, the number and percentage of patients with any treatment-emergent AEs (TEAEs), any 
serious AEs (SAEs), TEAEs related to study drugs, and TEAEs causing treatment discontinuation will be 
summarized. Adverse Events of Special Interest (AESI) (musculoskeletal pain, injection site reactions, and 
hypersensitivity reactions) will be assessed and summarized by Preferred Term. An exposure-response analysis 
will be performed based on sparse PK sampling. 
Sample size estimates are based on a non-inferiority design. The pooled standard deviation of the DSN is 
assumed to be 2.0 days, after referencing the assumptions used in the two Phase 3 registrational pegfilgrastim 
trials. The margin of non-inferiority is 0.62 days. The true difference between the means is assumed to be 0.0 
days. Sample sizes of 200 per treatment arm will provide 87% power to detect non-inferiority using a one-sided, 
two-sample t-test at 2.5% level of significance.  
The study will enroll and randomize approximately 200 patients per arm for a total of approximately 
400 patients.

1 INTRODUCTION 
1.1 Background 
1.1.1 Breast Cancer and Role of Granulocyte Colony Stimulating Factor 
According to the American Cancer Society (ACS), breast cancer is one of the most common 
forms of cancer and the second highest cause of cancer deaths in women [1]. In 2014 in the 
United States (US), an estimated 232,670 new cases of invasive breast cancer and 62,570 
additional cases of in situ breast cancer occurred, and approximately 40,430 US women were 
expected to die from breast cancer. In addition, breast cancer is also seen in males, with an 
estimated 2360 men being diagnosed with breast cancer and 410 dying from the disease in 2013. 
Data show that mortality rates from breast cancer increase with age, reaching a peak when 
patients are in their 70s [1].  
The National Comprehensive Cancer Network (NCCN) clinical guidelines recommend that most 
patients with early-stage breast cancer (ESBC) receive adjuvant chemotherapy after they have 
undergone complete surgical excision of the primary tumor by lumpectomy and axillary 
dissection or modified radical mastectomy [2]. Current NCCN guidelines for adjuvant 
chemotherapy regimens to treat ESBC include docetaxel, doxorubicin, and cyclophosphamide 
(TAC); dose dense doxorubicin plus cyclophosphamide (AC), with or without subsequent 
weekly or semiweekly paclitaxel; and docetaxel plus cyclophosphamide (TC).  
The use of adjuvant chemotherapy to improve survival in patients with ESBC has been widely 
adopted [3]. The TC regimen is an attractive therapeutic option because it has demonstrated 
efficacy [4] and reduced risk of cardiotoxicity compared with other therapies that contain 
anthracyclines [5]. USO 9735 was a pivotal Phase 3 trial that compared TC vs. AC among 
patients with operable ESBC [6]. Trial results showed that after 7 years of follow-up, 4 cycles of 
TC were associated with significantly improved Disease Free Survival (DFS) and Overall 
Survival (OS) compared with 4 cycles of AC. Specifically, the DFS was 81% and 75% for TC 
and AC, respectively, and the OS was 87% and 82%, respectively. Although the TC regimen has 
not been associated with cardiotoxicity [4, 6, 7], it has been associated with other adverse events, 
particularly hematologic toxicities [4, 6].  
In USO 9735, the reported rates of Febrile Neutropenia (FN) were 4% in women younger than 
65 years and 8% in those 65 years or older, although FN was not a pre-planned evaluable 
endpoint in the trial [4]. No dose reductions were permitted, and patients were taken off 
treatment if any study drug administration was delayed by more than 2 weeks because of drug-
related toxicities. Prophylactic use of quinolone antibiotics was recommended at the discretion of 
the treating physician. Prophylactic granulocyte colony-stimulating factor (G-CSF) was not 
allowed, and reactive G-CSF support for chemotherapy-induced neutropenic complications was 
not specified [4]. 
Subsequent reports have suggested that TC is associated with higher rates of FN than those 
reported in USO 9735, ranging from 25% to 50% in the absence of G-CSF support and 
decreasing to 0% to 6.3% with primary G-CSF prophylaxis (Table 1) [8-12].

Development of FN increases diagnostic and treatment costs, and often leads to prolonged 
hospitalizations. In addition, changes in neutrophil counts have been correlated with quality of 
life, as measured by physical functioning, vitality, and mental health [18].  
Filgrastim, tbo-filgrastim, and pegfilgrastim are G-CSFs currently approved by the US Food and 
Drug Administration (FDA) for the prevention of chemotherapy-induced neutropenia [15].While 
the European guidelines also include lenograstim as a recommended G-CSF in solid tumors and 
non-myeloid malignancies, it is not approved for use in the US. 
Studies have demonstrated that the use of G-CSF can reduce the risk, severity, and duration of 
FN [15]. Guidelines from the American Society of Clinical Oncology (ASCO), the European 
Organization for Research and Treatment of Cancer (EORTC) Guidelines, as well as NCCN 
recommend the use of G-CSF as primary prophylaxis when the anticipated risk of FN for a 
patient initiating chemotherapy is high [15, 19, 20].  
1.1.2 SPI-2012 
Spectrum Pharmaceuticals, Inc. (Spectrum) is developing a novel, long-acting form of G-CSF, 
SPI-2012 (also known as Rolontis™, eflapegrastim, HM10460A, Long Acting Protein/Peptide 
Discovery Platform Technology-G-CSF [LAPS-G-CSF]), a chemically conjugated form of a 
modified G-CSF, for the indication of the reduction in the Duration of Severe Neutropenia 
(DSN) and incidence of infection, as manifested by FN in patients with solid tumors and non-
myeloid malignancies receiving myelosuppressive anti-cancer therapy. SPI-2012 is a novel 
biologic and not a biosimilar to either filgrastim or pegfilgrastim. 
SPI-2012 is produced by conjugating a novel, modified recombinant human G-CSF (with no 
additional N-terminal Met, referred to as HM10411), and the human immunoglobulin G4 Fc 
fragment (referred to as HMC001) via a 3.4 kDa polyethylene glycol (PEG) linker to produce a 
new, long-acting G-CSF. 
HM10411 and HMC001 are each manufactured using recombinant-DNA technology in E. coli. 
Specifically, HM10411 is produced by fermentation of transformed E. coli in the periplasmic 
space followed by harvesting and purification. Whereas HMC001 is produced by fermentation of 
transformed E. coli as an inclusion body followed by harvesting, refolding, and purification. 
The human immunoglobulin G4 Fc fragment (HMC001) was specifically chosen as the 
conjugation partner for this novel G-CSF because it has a long in vivo half-life of several weeks. 
Details of the product’s characteristics can be found in the Investigator’s Brochure (IB).  
1.1.2.1 Nonclinical Studies 
The biological response to rh-G-CSF is not species specific, and therefore the biological 
response of rh-G-CSF has been examined in mice, rats, dogs, and monkeys in single- and repeat-
dose studies. Mouse bone marrow cells, chemotherapy-induced neutropenic mouse and rat 
models, normal and nephrectomized rats, and cynomolgus monkeys have all been used to 
study the effects of SPI-2012. All toxicology studies were performed under Good Laboratory 
Practice (GLP) conditions. 
The kinetics of neutrophil proliferation in neutropenic mice and rats stimulated with SPI-2012, 
pegfilgrastim, and filgrastim were also compared. SPI-2012 was shown to have an 
approximately 2-fold higher Area Under the Time-Concentration Curve (AUC) for Absolute

Neutrophil Count (ANC) when compared to pegfilgrastim at similar doses (ie, when comparing 
equivalent G-CSF concentrations of the compounds). Based on these results, SPI-2012 was 
estimated to have twice the in vivo potency as pegfilgrastim. The potential clinical benefit of the 
increased potency of SPI-2012 was analyzed by comparing the DSN in neutropenic rats to the 
DSN response to pegfilgrastim and filgrastim in this same model. SPI-2012 was found to be 
more potent in shortening the DSN with a lower G-CSF equivalent dose when compared to 
either pegfilgrastim or filgrastim. The DSN was 0.2 days when SPI-2012 was co-administered or 
sequentially administered as a single dose at 88 µg/kg (as G-CSF equivalent) with chemotherapy 
drugs in rats. In contrast, the DSN was 3.04 days with filgrastim administered at dose of 
20 µg/kg for 5 days and was 2.8 days with pegfilgrastim administered as a single dose of 
100 µg/kg. 
In cynomolgus monkeys, neutrophil counts increased as SPI-2012 dose levels increased (161.48 
to 322.96 μg/kg SPI-2012,) but were not dose-proportional. Maximum neutrophil levels peaked 
on Day 1 post-dose, decreased by Day 7 following IV administration, peaked on Day 3 post-
dose, and then decreased by Day 16 following SC administration of SPI-2012. SPI-2012 also 
showed an approximately 3-fold higher AUC for ANC compared to pegfilgrastim at the same 
G-CSF equivalent dosing level.  
1.1.2.2 Clinical Experience 
1.1.2.2.1 Phase 1 Studies 
Two Phase 1 studies of SPI-2012 (08-HM10460-101, N=60; 09-HM10460-101, N=30) were 
conducted in healthy volunteers to evaluate the safety and the pharmacokinetic (PK) and 
pharmacodynamic properties of SPI-2012. Most adverse events (AEs) reported in these studies 
were mild and comparable to those reported in other clinical trials with pegfilgrastim. Common 
treatment-related AEs included bone pain, back pain, and headache. No clinically significant 
changes were found in electrocardiogram (ECG), vital signs, or splenic evaluation. Isolated cases 
of tachycardia, palpitation, and transient elevations of liver enzymes were seen in some patients. 
Overall in the Phase 1 studies in healthy volunteers, doses of SPI-2012 between 1.1 µg/kg and 
350 µg/kg were generally well-tolerated and increased white blood cell (WBC) and neutrophil 
counts in a pronounced and dose-dependent manner.  
1.1.2.2.2 Phase 2 Study- SPI-GCF-12-201 
A Phase 2, open-label, dose-ranging, study (SPI-GCF-12-201, N=148) has also been completed. 
This study compared three weight-based doses of SPI-2012 (45, 135, and 270 µg/kg) versus 
pegfilgrastim (6 mg) for the management of neutropenia in breast cancer patients receiving TC 
chemotherapy, and provides safety and efficacy data supporting advancement to Phase 3 and the 
basis for the fixed dose recommendation. Brief results are presented below and additional results 
are presented in the Investigator’s Brochure (IB). 
1.1.2.2.2.1 Study Design 
SPI-GCF-12-201 was a Phase 2, open-label study to assess the effect of test doses of SPI-2012 
on the DSN during Cycle 1 in patients with breast cancer who were candidates for adjuvant or 
neoadjuvant chemotherapy with the docetaxel and cyclophosphamide (TC). 
The study included 4 single-dose treatment arms:

 Arm 1: SPI-2012 (45 μg/kg) 
 Arm 2: SPI-2012 (135 μg/kg) 
 Arm 3: SPI-2012 (270 μg/kg) 
 Arm 4: Pegfilgrastim (6 mg) 
Administration of TC on Day 1 of each cycle IV was:  
 Docetaxel at 75 mg/m2 IV infusion per Institute’s standard of care  
 Cyclophosphamide 600 mg/m2 IV infusion per Institute’s standard of care  
Each treatment cycle was 21 days with up to a maximum of 4 cycles of chemotherapy. To begin 
full-dose chemotherapy on Day 1 of the next cycle (Day 22 of the previous cycle), patients must 
have recovered to an ANC greater than 2.0×109/L and a platelet count ≥100×109/L. 
SPI-2012 was administered on Day 2 of each cycle, approximately 24 to 26 hours after TC 
chemotherapy. The dose of SPI-2012 administered depended on the treatment arm to which each 
patient was assigned. Pegfilgrastim was to be administered according to the manufacturer’s 
Prescribing Information (6 mg subcutaneously once per chemotherapy cycle).  
1.1.2.2.2.2 Disposition and Demographics 
In SPI-GCF-12-201, 148 patients were randomized into the 4 treatment arms. Most patients 
(147 patients [99%]) completed at least 1 cycle of treatment. Ten patients (7%) discontinued 
from the study. Three patients (2%) withdrew consent, two patients (1%) discontinued due to 
adverse events, and five patients discontinued for other reasons. Four patients (2 patients each in 
the 135 μg/kg SPI-2012 group [one patient withdrew consent and one patient initiated a non-
protocol therapy] and 270 μg/kg SPI-2012 dose group [both patients withdrew consent]) 
discontinued prior to beginning Cycle 2 and 138 patients (93%) were treated for all 4 cycles.  
The mean age of all patients in SPI-GCF-12-201 was 58.2 years and ranged from 32 years to 
77 years across all groups. Most patients were less than 65 years of age (n=100 [68%]), female 
(n=144 [98%]), and White (n=139 [95%]). There were 3 male patients in the study, two in the 
270 µg/kg SPI-2012 group and one in the 135 µg/kg SPI-2012 group. 
During Cycle 1 in SPI-GCF-12-201. During Cycle 1, most patients (≥64%) in all three SPI-
2012 dose groups and the pegfilgrastim group did not develop neutropenia; at SPI-2012 doses 
≥135 µg/kg, the proportion of patients not experiencing neutropenia was comparable or higher to 
the incidence with pegfilgrastim. 
1.1.2.2.2.3 Duration of Severe Neutropenia 
In the 270 µg/kg SPI-2012 group, neutropenia was reported in only one patient (3%), which 
lasted only 1 day. In the 135 µg/kg SPI-2012 group, seven patients (19%) experienced 
neutropenia, which lasted for 1 day in three patients (8%), 2 days in three patients (8%), and 
7 days in one patient (3%). Approximately one-third of patients in the 45 µg/kg SPI-2012 group 
experienced neutropenia that lasted between 1 to 5 days. In the pegfilgrastim group, five patients 
(14%) experienced neutropenia, which lasted for 1 day in one patient (3%), 2 days in two 
patients (6%), and 3 days in two patients (6%). The magnitude of DSN and the mean values in 
the various treatment arms may be much lower in this study as compared to that in the literature

clinical benefits of the prophylactic use of G-CSF for patient safety, to maximize treatment 
intensity and outcomes, and cost-efficiency. 
Pharmacological analysis of SPI-2012 in vivo revealed a 2- to 3-fold increase in the AUC of the 
ANC at G-CSF-equivalent doses similar to pegfilgrastim. Clinical experience from the Phase 2 
trial (SPI-GCF-12-201) in breast cancer patients has shown that SPI-2012 is non-inferior to 
pegfilgrastim and has a similar safety profile. All doses of SPI-2012 administered in 
SPI-GCF-12-201 were well tolerated. No significant dose-related toxicities were observed. The 
DSN in the 135 µg/kg SPI-2012 arm was non-inferior to pegfilgrastim in Cycle 1 and the DSN 
in the 270 µg/kg SPI-2012 Treatment Arm was superior to the Pegfilgrastim Treatment Arm. 
Non-inferiority in DSN was also observed in Cycles 2 to 4 in both the 135 µg/kg and 270 µg/kg 
treatment arms when compared to pegfilgrastim. 
The current Phase 3 study is designed to expand on the information obtained in the Phase 2 trial 
and evaluate the efficacy, and safety of SPI-2012, as compared with pegfilgrastim (Neulasta 
[NDC 55513-190-01] manufactured by Amgen in the United States), in breast cancer patients 
receiving TC.  
The dose of SPI-2012 to be studied in this trial is 13.2 mg SPI-2012 equivalent to 3.6 mg 
G-CSF, approximately half of the G-CSF equivalent dose in 6 mg pegfilgrastim. This dose was 
selected on the basis of the pharmacological and pharmacodynamic data from the Phase 2 trial 
(SPI-GCF-12-201).  
As applicable, patients who have received at least one dose of study drug (SPI-2012 or 
pegfilgrastim) will be followed for 12 months after the last dose of study treatment for safety 
follow-up. Patients will visit the clinic at approximately 6 months and 12 months for a blood 
draw for evaluation of immunogenicity and for evaluation of AEs, subsequent anti-cancer 
therapy, use of other myeloid growth factors, and participation in any other subsequent clinical 
trials. In addition, patients will also be contacted by telephone at approximately 3 months and 9 
months for evaluation of AEs, subsequent anti-cancer therapy, use of other myeloid growth 
factors, and participation in any other subsequent clinical trials.

Prior to TC chemotherapy administration, patients may receive pre-medications according to 
institutional standard of care. Intravenous (IV) administration of TC on Day 1 of each cycle will 
be as follows:  
 Docetaxel 75 mg/m2 IV infusion per institute’s standard of care 
 Cyclophosphamide 600 mg/m2 IV infusion per institute’s standard of care 
Each cycle will be 21 days. Only 4 cycles will be evaluated for this study. After Cycle 1, patients 
must have ANC ≥1.5 × 109/L and platelet count ≥100 × 109/L to begin the each of next cycles of 
chemotherapy.  
The study drug (SPI-2012 or pegfilgrastim) will be administered on Day 2 of each cycle, 
approximately 24 to 26 hours after the last dose of TC chemotherapy is given. Study drug (SPI-
2012 or pegfilgrastim) dose modifications are not allowed. 
On Day 1 of each cycle, patients will receive TC chemotherapy, and safety and efficacy 
assessments will be performed as outlined in Section 5.3. On Day 2 of each cycle, patients will 
receive study drug (SPI-2012 or pegfilgrastim), and the specified assessments will be performed. 
Patients will be monitored on Day 1 and Days 4 to 15 in Cycle 1. If the participating site is 
notified that the ANC is ≤1.0 × 109/L at any time during Cycle 1, then daily CBCs will be 
required until ANC is ≥1.5 × 109/L, after reaching nadir. In Cycles 2 to 4, all patients must have 
blood samples drawn on Day 1 (prior to chemotherapy administration), on Days 4, 7, 10, and 15 
(±1 day for each collection), and at the End-of-Treatment Visit. If the participating site is 
notified that the ANC is ≤1.0 × 109/L at any time during Cycles 2 to 4, then daily CBCs will be 
required until the ANC is ≥1.5 × 109/L, after reaching nadir, but blood samples must still be 
drawn on Days 4, 7, 10, and 15. As applicable, patients who have received at least one dose of 
study drug will be followed for approximately 12 months after the last dose of study treatment 
for safety follow-up.  
3.2 Study and Treatment Duration  
The duration of the SPI-GCF-301 study is approximately 34 months (22 months for enrollment 
and 12 months of treatment/follow-up). The total duration of the study for each patient in SPI-
GCF-301 will be for approximately 16 months including: 
 Screening Period: 30 days 
 Treatment Period: 4 cycles, 21 days per cycle 
 End-of-Treatment Visit: 35 (±5) days after last dose of study treatment 
 Safety Follow-up: 12 months after the last dose of study treatment 
 End-of-Study Visit: At the 12 Month Visit or 35 (±5) days after early discontinuation 
As applicable, patients who receive at least one dose of study drug will be followed for safety for 
12 months after the last dose of study treatment for safety follow-up.

administered to patients at any time during the treatment phase or follow-up. 
No white blood cell or whole blood transfusions are allowed. 
7 SAFETY ASSESSMENT 
7.1 Safety Measures 
It is the responsibility of the Principal Investigator to oversee the safety of the patients at their 
site and to report all AEs/SAEs that are observed or reported during the study, regardless of 
relationship to study drug or clinical significance.  
Safety data will also be reviewed on a regular basis by Spectrum’s study monitoring team, which 
includes a Clinical Research Associate (CRA), Medical Monitor, and other personnel from the 
company or its designee.  
Adverse events will be characterized by intensity (severity), causality, and seriousness by the 
Investigator based on the regulatory definitions included below. 
This study will utilize the National Cancer Institute (NCI) Common Terminology Criteria for 
Adverse Events (CTCAE) Scale Version 4.03 for AE grading. 
7.2 Adverse Events 
An AE is defined as any untoward medical occurrence in a patient or clinical investigation 
patient, temporally associated with the use of a medicinal product or study procedure, whether or 
not considered related to the medicinal product. Therefore, an AE can be any unfavorable and 
unintended sign (including an abnormal laboratory finding), symptom, or disease (new or 
exacerbated) temporally associated with the use of a medicinal product. A treatment-emergent 
AE (TEAE) is any AE that occurs from the first dose of study treatment through 12 months after 
the last dose of study treatment or 35 (±5) days after the date of patient early discontinuation. 
Additionally, as applicable, patients who receive at least one dose of study drug (SPI-2012 or 
pegfilgrastim) will be followed for safety for 12 months after the last dose of study treatment or 
date of patient early discontinuation. All AEs during this time period will be recorded. 
The study will record all AEs according to the information in Section 7.3.

Examples of AEs include: 
 Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition. 
 New conditions detected or diagnosed after investigational product administration. 
 Signs, symptoms, or the clinical sequelae of a suspected drug interaction. 
 Signs, symptoms, or the clinical sequelae of a suspected overdose of either 
investigational product or a concurrent medication. 
 AEs may include pre-treatment or post-treatment events that occur as a result of protocol-
mandated procedures, ie, invasive procedures. 
Abnormal laboratory results are to be recorded as AEs, if any of the following conditions are 
met: 
 The abnormal laboratory value leads to a therapeutic intervention. 
 The abnormal laboratory value is considered to be clinically significant by the 
Investigator. 
 The abnormal laboratory value is predefined as an AE in the protocol or in another 
document communicated to the Investigator by Spectrum or designee. 
 The abnormal laboratory value is ≥Grade 3 based on CTCAE Version 4.03. 
Examples of events that do not constitute AEs include: 
 Medical or surgical procedures (eg, endoscopy, appendectomy); the condition that leads 
to the procedure is an AE. 
 Situations where an untoward medical occurrence does not occur (eg, social and/or 
convenience admission to a hospital). 
 Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or 
detected at the start of the study that do not worsen.  
 Planned and prescheduled hospitalizations and procedures.  
 Progressive disease. 
7.3 Guidelines for Recording and Attribution Scoring of Adverse Events 
Timely and complete reporting of all AEs is required for all patients. Monitoring and 
documentation of all AEs allows for identification of potential study-drug or dose-related AEs, 
and for adherence to regulatory requirements. Please refer to the CRF Completion Guidelines 
located in the study binder for detailed instructions for AE reporting. 
7.3.1 Recording of Adverse Events 
All AEs that occur from the first dose of study treatment through 35 (±5) days after last dose of 
study treatment (SPI-2012 or pegfilgrastim) or 35 (±5) days after the date of patient early 
discontinuation are to be recorded on the AE CRF. Additionally, all patients who receive at least 
one dose of study drug will have all AEs recorded through the end of the 12 Month Safety 
Follow-up Period. From the time the study ICF is signed through the first dose of study drug 
administration, only SAEs that are related to study procedures are to be recorded.

Spectrum may request additional information from the Investigator to ensure the timely 
completion of accurate safety reports. Safety data that are critical to the reportability of an SAE, 
such as causality assessment and seriousness criteria, should be included in the initial faxed or 
e-mailed SAER. If omitted, a timely response to drug safety data queries received from Spectrum 
or designee is expected. 
The Investigator is to take all appropriate therapeutic measures necessary for resolution of SAEs. 
Any medications necessary for treatment of the SAE are to be recorded in the concomitant 
medication section of the patient’s CRF. 
SAEs that are study treatment-related will be followed until resolution or until they have returned 
to Grade 1, whichever is longer, or until it is determined that the outcome will not change with 
further follow-up. 
Additionally, the SAE is to be entered in the AE CRF. Follow-up SAERs need to be submitted to 
Spectrum within 24 hours once additional information regarding the event becomes available 
(eg, final diagnosis is made, laboratory or test results, event course, outcome, etc).  
Spectrum or designee will be responsible for reporting SAEs to the regulatory authorities in 
accordance with applicable expedited reporting regulatory guidelines. The Investigator is 
responsible for submitting SAEs to his/her local Institutional Review Board (IRB)/Ethics 
Committee (EC). Copies of each SAER, and documentation of IRB/EC notification and 
acknowledgement of receipt, will be kept in the Site’s Regulatory Binder. 
7.7.2 Exclusions to Serious Adverse Event Reporting Requirements 
The following are not considered SAEs: 
 Situations where an untoward medical occurrence did not occur (eg, social and/or 
convenience admission to a hospital, hospitalization for diagnostic tests such as CT 
scans). 
 Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or 
detected prior to first study treatment administration that do not worsen.

7.8 Reproductive Risks 
No adequate and well-controlled studies of SPI-2012 have been conducted in pregnant women. 
The effects of SPI-2012 on fertility and fetal development have not been studied in pregnant 
women. SPI-2012 is not recommended for use during pregnancy. 
Pregnancies involving a study patient or a patient’s partner, that occur from the first dose of 
study treatment through 35 (±5) days after last dose of study drug administration or 35 (±5) days 
after the date of patient early discontinuation, will be reported within 24 hours after the 
Investigator has gained knowledge of the event via fax or e-mail (see contact information in 
Section 7.7.1). Pregnancies should be followed up until outcome and follow-up information 
regarding the outcome of the pregnancy should be faxed or e-mailed to Spectrum’s 
Pharmacovigilance Department.  
All patients who become pregnant during participation in this study are to be withdrawn from the 
study. 
8 STATISTICAL PLAN  
This section contains a brief overview of the statistical analyses planned for this study. A formal 
statistical analysis plan (SAP) will be finalized prior to first patient enrolled.  
8.1 Sample Size  
Approximately 400 patients will be enrolled in this study. The primary endpoint analysis is based 
on the test of non-inferiority of SPI-2012 as compared to pegfilgrastim. The pooled standard 
deviation of DSN is assumed to be 2.0 days, after referencing the assumptions used in the two 
Phase 3 registrational pegfilgrastim trials [28]. The standard deviation used for sample size 
calculation in the two Phase 3 pegfilgrastim trials was 2.17 and 1.5 days, respectively.  
For the test of non-inferiority hypothesis, the margin of non-inferiority to be used in the study is 
0.62 day. The true difference between the means is assumed to be 0.0 days. Sample sizes of 
200patients per treatment arm will achieve 87% power to detect non-inferiority using a one-
sided, two-sample t-test at 2.5% level of significance. The study will enroll and randomize 200 
patients per arm for a total of approximately 400 patients.  
The non-inferiority of SPI-2012 to pegfilgrastim will be declared if the upper bound of 95% CI 
of the difference in mean DSN between the treatment arms is <0.62 days.  
8.2 Method of Treatment Assignment, Randomization, and/or Stratification 
The patients enrolled in this study will be randomized at a 1:1 ratio to the SPI-2012 and 
pegfilgrastim treatment arms and stratified by study site. A randomization scheme using a 
permuted block design will be developed. An interactive web response system will be used to 
assign a randomization identification (ID) once patients meet eligibility criteria and are ready to 
be randomized. The randomization ID will be different than the Patient ID, and a mapping of 
randomization ID to Patient ID will be kept in a secured database.

8.3 Analysis Populations 
 Intent-to-Treat Population (ITT): will consist of all patients who are randomized. 
Patients will be analyzed as randomized if the actual treatment assignments deviate from 
the randomization scheme.  
 Per Protocol (PP) Population: will include all patients in the ITT population with no 
major protocol deviation in Cycle 1. Patients will be analyzed as treated if the actual 
treatment assignments deviate from the randomization scheme.  
 Safety Analysis Population (SAF): will consist of all patients who receive at least one 
dose of any protocol-specified drug (TC or SPI-2012 or pegfilgrastim) 
Patients who discontinue from the study prior to randomization will be replaced as they are not 
considered to be the ITT patients.  
8.4 General Statistical Methods 
Spectrum’s Biostatistics and Data Management (BDM) group (or a contracted data management 
vendor) will be responsible for data management and statistical analysis of this study. All 
statistical analyses will be performed using SAS for Windows (version 9.3 or higher). Patient 
data listings and tabular presentations of results will be provided. Further details of the criteria 
and conduct of the statistical analyses will be included in the Statistical Analysis Plan for this 
study to be finalized prior to first patient enrolled. 
8.5 Efficacy Analyses 
8.5.1 Primary Endpoint 
The primary analysis of the comparison of the DSN in Cycle 1 between the SPI-2012 
Treatment Arm and the Pegfilgrastim Treatment Arm will be conducted using the ITT 
Population. 
DSN in Cycle 1 is defined as the number of days of severe neutropenia (ANC <0.5×109/L) from 
the first occurrence of an ANC below the threshold. The assessment of ANC will be performed 
on Day1 and Days 4-15 in Cycle 1. The endpoint will be measured in all patients in the ITT 
Population. For patients who do not meet severe neutropenia criteria, the endpoint measurement 
will be defined as DSN=0. 
For the primary efficacy analysis, the mean DSN in Cycle 1 will be compared between the 
SPI-2012 Treatment Arm and the Pegfilgrastim Treatment Arm using a bootstrap resampling 
method with non-inferiority hypothesis. A 2-sided 95% confidence interval (CI) of the difference 
between the mean DSN of the SPI-2012 Treatment Arm and the mean DSN of the 
Pegfilgrastim Treatment Arm will be calculated using bootstrap resampling with treatment as 
the only stratification factor. The study will use non inferiority margin of 0.62 days for the above 
comparison. The non-inferiority of SPI-2012 to pegfilgrastim will be declared if the upper bound 
of 95% CI of the difference in mean DSN between the treatment arms is <0.62 days.  
Primary analysis for the non-inferiority hypothesis will be based on the ITT population. An 
analysis based on the PP Population will be performed as a sensitivity analysis.  
In addition to bootstrap resampling method to calculate 95% CI of the difference in mean DSN 
between treatment arms, the test of the difference in mean DSN between treatment arms will be

47 
conducted using Poisson distribution as another sensitivity analysis. If the data is overdispersed, 
a negative binomial distribution will be incorporated for the test. For the Poisson and negative 
binomial regression, the identical link will be used and treatment will be the only covariate in the 
model. The difference in mean DSN between SPI-2012 and pegfilgrastim will be calculated 
along with 2-sided 95% CI, based on Poisson or negative binomial regression. Based on the 
initial review of the efficiency of the estimates of bootstrap, Poisson and negative binomial 
distributions, 95% CI calculated using bootstrap resampling method appear to be robust and 
therefore is proposed to be the primary analysis method for the primary endpoint. Detailed 
simulation results will be provided along with SAP.  
Additional sensitivity analyses will also be used to examine the: 
 Treatment effect, adjusting for the various study sites. This analysis will be carried out 
using the same methodology as the primary analysis (bootstrap resampling method), and 
study site will be used as an additional stratification factor in the resampling.  
 Treatment effect, adjusting for disease status at randomization (adjuvant or neoadjuvant). 
This analysis will be the same as the primary analysis (bootstrap resampling method) and 
disease status will be used as additional stratification factor in the resampling. 
 Impact of missing data, using a worst case scenario. When ANC data are missing on or 
after Day 5, and before patients’ ANC increase to ≥1.5×109/L after the expected nadir in 
Cycle 1, missing ANC values will be imputed as <0.5×109/L for SPI-2012 and ≥0.5×
109/L for pegfilgrastim, for the purpose of DSN calculation. The method of analysis of 
imputed DSN data using worst case scenario will be the same as the primary analysis 
(bootstrap resampling method).  
In addition, the following subgroups will be examined for DSN in Cycle 1:  
 Age: <65 years, ≥65 years 
 Gender (Male, Female) 
 Race 
 Disease Status (Adjuvant, Neoadjuvant) at randomization 
 Geographic Region  
 Weight: <65 kg, 65 to 75 kg, or >75 kg 
8.5.2 Key Secondary Endpoints 
 To compare SPI-2012 with pegfilgrastim in:  
 Time to ANC Recovery in Cycle 1, defined as the time from chemotherapy 
administration until the patient’s ANC increases to ≥1.5×109/L after the expected 
nadir. For patients with ANC value ≥1.5×109/L at all times, Time to ANC Recovery 
will be assigned to a value of 0. 
 Depth of ANC Nadir, defined as the patient’s lowest ANC in Cycle 1 
 Incidence of FN in patients during Cycle 1, in which FN is defined as an oral 
temperature >38.3°C (101.0°F) or two consecutive readings of >38.0°C (100.4°F) for 
2 hours and ANC <1.0×109/L

 Safety 
The analyses of Key Secondary Endpoints will employ a hierarchical closed testing procedure 
[29], where endpoints are ranked with the primary endpoint first and then the Key Secondary 
Endpoints in the order listed above. Specifically, the order of testing is: 
1. DSN in Cycle 1 
2. Time to ANC Recovery in Cycle 1 
3. Depth of ANC Nadir in Cycle 1 
4. Incidence of FN in Cycle 1 
For the secondary efficacy analyses, the results will each be summarized by Treatment Arm and 
Cycle and will use the ITT population. Two-sided 95% CI for the difference between the 
treatment arms will be calculated. 
No adjustment to alpha will be necessary once the preceding endpoint comparison is significant 
for the subsequent endpoints in the above order of endpoints, with each test at the same 
significance level of α=0.05. 
8.6 Analysis of Safety 
The overall incidence of treatment-emergent AEs (TEAE) (ie, AEs occurring from the time the 
first dose of the study drug through 12 months after the last dose of study drug administration or 
35 (±5) days after the date of patient early discontinuation) and the proportion of patients who 
discontinue because of a TEAE are the primary safety outcome measures.  
The number and percent of patients with new-onset TEAEs will be summarized by the MedDRA 
System-Organ-Class (SOC) level and Preferred Term (PT) for all treated patients. The summary 
of TEAEs will be presented in the following categories:  
 Number and percentage of patients with any TEAEs by SOC and PT. 
 Number and percentage of patients with any SAEs by SOC and PT. 
 Number and percentage of patients with related TEAEs by SOC and PT. 
 
Related to TC 
 
Related to SPI-2012 
 
Related to pegfilgrastim  
 Number and percentage of patients with TEAEs causing discontinuation of the study by 
SOC and PT.
