Brief Summary

Neutropenia, a decrease in the number of neutrophils, a type of white blood cell, due to the myelosuppressive effects of chemotherapeutic drugs, is a frequent occurrence in patients receiving anticancer drug therapy, which increases the risk of infection, which can have serious consequences such as antibiotic treatment, hospitalization, intensive care unit treatment, and death, and also reduces the effectiveness of anticancer treatment due to dose reduction and cycle delay. Therefore,G-CSF,which acts as a neutrophil growth factor, can be administered immediately after chemotherapy to increase the production rate of neutrophils and promote the efflux of mature neutrophils from the bone marrow, thereby increasing the absolute neutrophil count. Guidelines for the use of G-CSF published by the NCCN indicate that primary prophylaxis with G-CSF has clinical benefit for patients receiving anticancer drug therapy with a risk of febrile neutropenia greater than 20%. For those at 10-20% risk, consider primary prophylaxis based on risk factors. The frequency of neutropenic fever with FOLFIRINOX chemotherapy, which is commonly used in patients with locally advanced or metastatic pancreatic cancer, was 5.4% in a prospective study of patients receiving high-dose regimens, but 42.5% of patients received prophylactic G-CSF, and 63.0% of patients received prophylactic G-CSF compared to 3.0% when given as postoperative adjuvant therapy demonstrating the need for G-CSF administration.In a retrospective study in Japan, a modified FOLFIRINOX chemotherapy regimen without pegylated G-CSF was associated with a 23% incidence of neutropenic fever and 61.5% grade 3-4 neutropenia, while prophylactic administration of pegylated G-CSF was associated with zero neutropenic fever and grade 3-4 neutropenia and longer survival .A retrospective study from Korea also reported that prophylactic G-CSF administration reduced neutropenic fever from 18.5% to 1.8% and Grade 3-4 neutropenia from 55.6% to 31.6 in pancreatic cancer patients receiving FOLFIRINOX .Pegteograstim (Neulapeg®) is a pegylated human recombinant granulocyte colony-stimulating factor with a long half-life (15-80 hours) compared to filgrastim (3-4 hours). Although several studies have demonstrated that G-CSF primary prophylaxis reduces the frequency of hematologic toxicities, particularly febrile neutropenia, during chemotherapy, it has not been prospectively studied whether primary prophylaxis reduces the frequency of grade 3-4 neutropenia and neutropenic fever in the modified FOLFIRINOX chemotherapy regimen in patients with pancreatic cancer. Therefore, this study is designed to determine if prophylactic administration of NEURAPEC reduces the frequency of Grade 3-4 neutropenia and neutropenic fever in patients with locally advanced or metastatic pancreatic cancer receiving modified FOLFIRINOX chemotherapy.

Detailed Description

1. Subjects who meet the inclusion/exclusion criteria for this study will be randomized to two arms, Arm A and Arm B, alternating between patients receiving prophylactic Neulapeg and patients not receiving prophylactic Neulapeg. Once assigned, they will be followed until the end of the 8th cycle of modified FOLFIRINOX.

2. Patients assigned to the arm receiving prophylactic Neulapeg will receive Neulapeg subcutaneously 24 hours after the end of modified FOLFIRINOX dosing. (This should be administered no later than 72 hours, and Neulapeg will only be given for a maximum of 8 cycles.)

3. Patients in both arms will have additional visits at the discretion of the investigator for hematologic toxicity surveillance on days 7-10 of modified FOLFIRINOX dosing during the first 4 cycles. Thereafter, patients will be seen only at the time of chemotherapy administration at the discretion of the investigator.

4. Patients in both arms will be instructed to return for any fever greater than 38.3 degrees Celsius or greater than 38.0 degrees Celsius lasting more than 1 hour.

5. Patients assigned to the arm not receiving prophylactic Neulapeg will not receive intervention with G-CSF for neutropenia of grade 2 or less.

6. Patients assigned to the no prophylactic Neulapeg arm will be crossover to prophylactic Neulapeg if they develop Grade 3-4 neutropenia or neutropenic fever. Crossover subjects will receive up to 8 cycles of prophylactic Neulapeg as a secondary treatment regardless of starting cycle.

7. Hematologic toxicity monitored every cycle for 8 cycles / Quality of life assessed according to EORTC QLQ-C30 at baseline, once every 2 weeks for a total of 5 times (Baseline, Cycle 2 Day 1, Cycle 4 Day1 , Cycle 6 Day 1 , Cycle 8 Day 1) / completion of the bone pain questionnaire at baseline, once every 1 cycle for the first 4 cycles, and then every 2 cycles for a total of 7 times (Baseline, Cycle 1 Day 1, Cycle 2 Day 1, Cycle 3 Day 1, Cycle 4 Day 1, Cycle 6 Day 1, Cycle 8 Day 1). The mFOLFIRINOX will be administered every 2 weeks for up to 8 cycles, while Neulapeg will be administered within 24-72 hours of the end of dosing and will be available for up to 8 cycles only. The crossover control arm will continue as usual.

8. The modified FOLFIRINOX chemotherapy regimen will be administered at the original dose at the start of Cycle 1, with subsequent dose deferral until recovery of a neutrophil count ≥1,000 /mm3 in the event of toxicity, with dose reduction at the discretion of the investigator.
