warnings

5.1 Splenic Rupture Splenic rupture, including fatal cases, can occur following the administration of recombinant human granulocyte colony-stimulating factor (rhG CSF) products, such as RYZNEUTA. Evaluate for an enlarged spleen or splenic rupture in patients who report left upper abdominal or shoulder pain after receiving RYZNEUTA.

warnings

5.2 Acute Respiratory Distress Syndrome Acute respiratory distress syndrome (ARDS) can occur in patients receiving rhG-CSF products, such as RYZNEUTA. Evaluate patients who develop fever and lung infiltrates or respiratory distress after receiving RYZNEUTA for ARDS. Discontinue RYZNEUTA in patients with ARDS.

warnings

5.3 Serious Allergic Reactions Serious allergic reactions, including anaphylaxis, can occur in patients receiving rhG-CSF products, such as RYZNEUTA. Permanently discontinue RYZNEUTA in patients with serious allergic reactions. RYZNEUTA is contraindicated in patients with a history of serious allergic reactions to RYZNEUTA or other rhG-CSF products such as pegfilgrastim, eflapegrastim or filgrastim products.

warnings

5.4 Sickle Cell Crisis in Patients with Sickle Cell Disorders Severe and sometimes fatal sickle cell crises can occur in patients with sickle cell disorders receiving rhG-CSF products, such as RYZNEUTA. Discontinue RYZNEUTA if sickle cell crisis occurs.

6. ADVERSE REACTIONS The following clinically significant adverse reactions are discussed in greater detail in other sections of the labeling: Splenic Rupture [see Warnings and Precautions ( 5.1 )] Acute Respiratory Distress Syndrome [see Warnings and Precautions ( 5.2 )] Serious Allergic Reactions [see Warnings and Precautions ( 5.3 )] Sickle Cell Crisis in Patients with Sickle Cell Disorders [see Warnings and Precautions ( 5.4 )] Glomerulonephritis [see Warnings and Precautions ( 5.5 )] Leukocytosis [see Warnings and Precautions ( 5.6 )] Thrombocytopenia [see Warnings and Precautions ( 5.7 )] Capillary Leak Syndrome [see Warnings and Precautions ( 5.8 )] Potential for Tumor Growth Stimulatory Effects on Malignant Cells [see Warnings and Precautions ( 5.9 )] Myelodysplastic Syndrome (MDS) and Acute Myeloid Leukemia (AML) in Patients with Breast and Lung Cancer [see Warnings and Precautions ( 5.10 )] Aortitis [see Warnings and Precautions ( 5.11 )] Most common adverse reactions (≥10%) were nausea, anemia, and thrombocytopenia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Evive Biotechnology Singapore Pte. Ltd. at 1-888-292-9617 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The following adverse reaction data are based on two studies [see Clinical Studies ( 14 )] . The first was a randomized, double-blind, placebo-controlled study in patients with metastatic or non-metastatic breast cancer receiving doxorubicin 60 mg/m2 and docetaxel 75 mg/m 2 every 21 days (Study GC-627-04). A total of 122 female patients were randomized to receive either 20 mg RYZNEUTA (n=83) or placebo (n=39) in chemotherapy cycle 1; all patients received RYZNEUTA in cycles 2-4. The second was a randomized, open-label, active-controlled study in patients with stage I to III invasive breast cancer receiving docetaxel 75 mg/m 2 and cyclophosphamide 600 mg/m 2 (Study GC-627-05). A total of 393 patients were randomized to receive either 20 mg RYZNEUTA (n=197) or pegfilgrastim (n=196) in chemotherapy cycles 1 through 4. In Study GC-627-04, the most common adverse reactions (≥10%) in the RYZNEUTA arm through cycle 1 were nausea, anemia, and thrombocytopenia (see Table 1). Other adverse reactions reported by ≥ 20% of RYZNEUTA-treated Patients with Breast Cancer Receiving Myelosuppressive Chemotherapy in Study GC-627-05 were fatigue and bone pain. Table 1. Adverse Reactions Adverse reactions that occurred in ≥10% of Ryzneuta-treated patients and ≥5% more than placebo-treated patients. in Study GC-627-04 in RYZNEUTA-treated Patients with Breast Cancer Receiving Myelosuppressive Chemotherapy Through Cycle 1 Adverse Reactions Ryzneuta (n=83) Placebo (n=39) Nausea 42 (51) 15 (39) Anemia 12 (15) 4 (10) Thrombocytopenia 10 (12) 1 (3)
