Relapsed or Refractory T-ALL and T-LBL Nelarabine injection was studied in 459 patients in Phase I and Phase II clinical trials. Adult Patient: The safety profile of Nelarabine injection is based on data from 103 adult patients treated with the recommended dose and schedule in 2 studies: an adult T-cell acute lymphoblastic leukemia (T-ALL)/T-cell lymphoblastic lymphoma (T-LBL) trial and an adult chronic lymphocytic leukemia trial. The most common adverse reactions in adults were fatigue; gastrointestinal (GI) disorders (nausea, diarrhea, vomiting, and constipation); hematologic disorders (anemia, neutropenia, and thrombocytopenia); respiratory disorders (cough and dyspnea); nervous system disorders (somnolence and dizziness); and pyrexia. The most common adverse reactions in adults by Body System, including severe or life-threatening adverse reactions (NCI CTCAE Grade 3 or Grade 4) and fatal adverse reactions (Grade 5) are shown in Table 1.
