Alanine aminotransferase and/or aspartate aminotransferase =3x ULN if baseline was normal; or =3x baseline if baseline was abnormal and/or total bilirubin >1.5 ULN. ? No improvement after 72h treatment with at least 1 mg/kg BW/day prednisolone equivalent o Pneumonitis ? Radiographic changes that involve more than one lobe of the lung or =25% of lung parenchyma and new symptoms such as cough, dyspnea or chest painor new oxygen therapy ?
