Adverse Reactions
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Myelosuppression [see Warnings and Precautions ( 5.1 )] Seizures [see Warnings and Precautions ( 5.2 )] Skin Disorders [see Warnings and Precautions ( 5.3 )] Injection Site Reactions and Tissue Necrosis [see Warnings and Precautions ( 5.4 )] Secondary Malignancies [see Warnings and Precautions ( 5.5 )] The most common adverse reactions (≥20%) are musculoskeletal pain, stomatitis, pyrexia, nausea, edema, infection, and vomiting.
( 6.1 ) Selected Grade 3 or 4 nonhematological laboratory abnormalities are increased GGT, increased bilirubin, increased ALT, increased AST, and increased creatinine.

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 to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
MC‑FludT.14/L Trial II The safety of GRAFAPEX was evaluated in 553 adult patients with AML and MDS in a randomized trial (MC‑FludT.14/L Trial II) comparing GRAFAPEX in combination with fludarabine to busulfan in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation.
The patients were randomized to receive GRAFAPEX (n=270) 10 g/m² daily on day -4, -3 and -2 or to busulfan (n=283) 0.8 mg/kg every 6 hours on day -4 and -3 in combination with fludarabine 30 mg/m 2 daily on day -6, -5, -4, -3 and -2, and hematopoietic stem cell transplantation on day 0 [see Clinical Studies ( 14 )] .
Fatal regimen-related adverse reactions occurred within 30 days of transplantation in 1.9% of patients on the GRAFAPEX arm.
All fatalities were due to pulmonary adverse reactions.
The most common adverse reactions (≥20%) in patients treated with GRAFAPEX were musculoskeletal pain, stomatitis, pyrexia, nausea, edema, infection, and vomiting.
Selected Grade 3 or 4 nonhematological laboratory abnormalities were increased GGT, increased bilirubin, increased ALT, increased AST, and increased creatinine.

One patient on the GRAFAPEX arm had graft failure.
