GPT and lymphopenia: Eleven AEs were classified as severe: 4 cases of elevated alanine aminotransferase (peak, 13.4 times the upper limit of normal), 1 case of elevated aspartate aminotransferase (peak, 7.3 times the upper limit of normal), 3 cases of pyrexia (peak, 39.8°C), and 3 cases of lymphopenia (lowest lymphocyte count, 0.41 × 109/L).
