Study summary

The study will assess the efficacy of LA-EP2006 compared to Neulasta® with respect to the mean duration of severe neutropenia during treatment with myelosuppressive chemotherapy in breast cancer patients.

Read the detailed description

The Pegfilgrastim Randomized Oncology (Supportive Care) Trial to Evaluate Comparative Treatment (PROTECT-2) was a confirmatory efficacy and safety study designed to compare the proposed biosimilar LA-EP2006 with the reference pegfilgrastim in woman with early stage breast cancer receiving (neo)-adjuvant myelosuppressive chemotherapy. Patient received TAC (intravenous docetaxel 75mg/m\^2, doxorubicin 50 mg/m\^2, and cyclophosphamide 500mg/m\^2) on day1 of each cycle, for six or more cycles. A total of 308 patients were randomized to LA-EP2006 (n=155) or reference Neulasta® (n=153). Treatment was given subcutaneously on day 2 of each cycle. The primary end point was the duration of severe neutropenia (DSN) during Cycle 1 (defined as number of consecutive days with absolute neutrophil count \<0.5 × 10\^9 cells/L). LA-EP2006 was equivalent to the reference product in DSN (difference: -0.16 days; 95% CI [-0.40, 0.08]). Further, LA-EP2006 and the reference pegfilgrastim showed no clinically meaningful differences regarding efficacy and safety.

What researchers measure

Primary outcomes

  1. Mean Duration of Severe Neutropenia (DSN) During Cycle 1 of Chemotherapy

    Mean duration of severe neutropenia, defined as number of consecutive days with ANC \<0.5 × 10\^9/l (grade 4 neutropenia).

    Time frame: 21 days (Cycle 1 of chemotherapy treatment)

Secondary outcomes

  1. Incidence of Febrile Neutropenia (FN)

    FN was defined as oral temperature ≥ 38.3°C while having an absolute neutrophil count (ANC) \< 0.5 × 10\^9 cells/L. Serious treatment-emergent adverse events (TEAEs) were reconciled with the fever and ANC results recorded in the patient diary and CRF and therefore only the serious TEAEs of FN ("febrile neutropenia", "neutropenic sepsis") were taken into account.

    Time frame: across all cycles (18 weeks)

  2. Number of Patients With at Least One Episode of Fever by Cycle and Across All Cycles

    Fever was defined as an oral body temperature of ≥ 38.3°C. Fever episodes were described by maximum oral temperature and the number of patients who had fever at least once.

    Time frame: across al cycles (18 weeks)

  3. Depth of ANC Nadir in Cycle 1

    The depth of ANC nadir was defined as the patient's lowest ANC (10\^9 cells/L) in Cycle 1.

    Time frame: Cycle 1 (3 weeks)

  4. Number of Patients With ANC Nadir Per Day in Cycle 1

    Numbers of patients with ANC nadir based per day during Cycle 1 are given.

    Time frame: Cycle 1 (3 weeks)

  5. Time to ANC Recovery in Days in Cycle 1

    Time to absolute neutrophil count (ANC) recovery was defined as the time in days from ANC nadir until the patient's ANC had increased to ≥ 2 × 10\^9 cells/L after the nadir in Cycle 1.

    Time frame: across Cycle 1 (3 weeks)

  6. Frequency of Infections by Cycle and Across All Cycles

    The number of patients with infections was recorded for each cycle and across all cycles. Infections were identified by the AE documentation page selecting all events coded with System Organ Class "Infections and Infestations".

    Time frame: across all cycles (18 weeks)

  7. Mortality Due to Infection

    Number of patients with death due to infections

    Time frame: Study course (19 weeks)
