Brief Summary

The purpose of this study is to compare the efficacy of SPI-2012 versus pegfilgrastim in participants with early-stage breast cancer receiving docetaxel and cyclophosphamide (TC) as measured by the duration of severe neutropenia (DSN).

Detailed Description

This is a Phase 3, randomized, open-label, active-controlled, multicenter study to compare the efficacy and safety of SPI-2012 versus pegfilgrastim in participants with early-stage breast cancer treated with TC chemotherapy as measured by the duration of severe neutropenia (DSN).

Each cycle was 21 days. Four cycles were evaluated for this study. On Day 1 of each cycle, participants received TC chemotherapy. On Day 2 of each cycle, participants received study drug (SPI-2012 or pegfilgrastim).

After cycle 1, as applicable, participants who received at least one dose of study drug will be followed for safety for 12 months after the last dose of study treatment.

Primary Outcome Measures
NameTimeMethod
Duration of Severe Neutropenia (DSN) in Cycle 1Day 1 and daily on Days 4-15 in Cycle 1 (each cycle = 21 days)

DSN was defined as the number of days of severe neutropenia (absolute neutrophil count \[ANC\] \<0.5×10\^9 per liter \[L\]) from the first occurrence of ANC below the threshold.

Secondary Outcome Measures
NameTimeMethod
Time to Absolute Neutrophil Count (ANC) Recovery in Cycle 1Day 1 and daily on Days 4-15 in Cycle 1 (each cycle = 21 days)

Time to ANC recovery was defined as the time from chemotherapy administration until the participants ANC increased to \>=1.5×10\^9/L after the expected nadir. For participants with ANC value \>=1.5×10\^9/L at all times, time to ANC Recovery was assigned a value of 0.

Duration of Severe Neutropenia (DSN) in Cycles 2, 3 and 4Days 1, 4, 7, 10, and 15 of Cycles 2, 3, and 4 (each cycle = 21 days)

DSN was defined as the number of days of severe neutropenia (ANC \<0.5×10\^9/L) from the first occurrence of ANC below the threshold.

Number of Participants With Febrile Neutropenia (FN) in Cycle 1Day 1 and daily on Days 4-15 in Cycle 1 (each cycle = 21 days)

FN was defined as an oral temperature \>38.3 degree Celsius (°C) (101.0 degrees Fahrenheit \[°F\]) or two consecutive readings of \>38.0°C (100.4°F) for 2 hours and ANC \<1.0×10\^9/L.

Number of Participants With Neutropenic Complications in Cycle 1Day 1 and daily on Days 4-15 in Cycle 1 (each cycle = 21 days)

Neutropenic complications refer to hospitalizations due to neutropenic events and/or the use of anti-infectives due to neutropenia.

Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs), and DeathUp to 4 cycles (each cycle = 21 days) plus a 12-month follow-up from the last dose (up to 15 months)

An adverse event (AE) is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product or study procedure, whether or not considered related to the medicinal product. A TEAE is any AE that occurred from the first dose of study treatment through 12 months after the last dose of study treatment or 35 (±5) days after date of participant early discontinuation. SAE is defined as any AE which meets any of the following criteria: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in a persistent or significant disability/incapacity, results in a congenital anomaly/birth defect, includes important medical events.

Depth of ANC Nadir in Cycle 1Day 1 and daily on Days 4-15 in Cycle 1 (each cycle = 21 days)

The depth of ANC Nadir was defined as the lowest ANC value after administration of study drug (SPI-2012 or pegfilgrastim) in Cycle 1.

Relative Dose Intensity (RDI) of TC ChemotherapyCycles 1, 2, 3 and 4 (each cycle = 21 days)

RDI was defined as the percentage of the planned dose of TC chemotherapy that each participant actually received during the study, and is expressed as the total dose received, divided by total dose planned multiplied by 100. The planned dose was defined as the dose that would be given if no doses were missed and/or no dose reductions were made for the number of cycles started. The total planned dose was the sum of planned doses over all cycles.

Clinically significant findings in laboratory parameters were based on investigator's discretion according to Common Technical Criteria for Adverse Events (CTCAE) Version 4.03.

Number of Participants With Febrile Neutropenia in Cycles 2, 3 and 4Days 1, 4, 7, 10, and 15 of Cycles 2, 3, and 4 (each cycle = 21 days)
