Use in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation in adult and pediatric patients 1 year of age and older with myelodysplastic syndrome (MDS).. Acute Myeloid Leukemia Treosulfan is indicated in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation in adult and pediatric patients 1 year of age and older with acute myeloid leukemia (AML). Myelodysplastic Syndrome Treosulfan is indicated in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation in adult and pediatric patients 1 year of age and older with myelodysplastic syndrome (MDS).

Boxed warning. MYELOSUPPRESSION Treosulfan causes severe and prolonged myelosuppression at the recommended dosage. Hematopoietic stem cell transplantation is required to prevent potentially fatal complications of the prolonged myelosuppression. Monitor hematologic laboratory parameters. WARNING: MYELOSUPPRESSION See full prescribing information for complete boxed warning. Treosulfan causes severe and prolonged myelosuppression. Seizures: Monitor signs of neurological adverse reactions and consider clonazepam prophylaxis for patients at higher risk. Skin disorders: Keep skin clean and dry on days of Treosulfan infusion and change occlusive dressings after infusion. Change diapers frequently during the 12 hours after each infusion of Treosulfan. Injection Site Reactions and Tissue Necrosis: May cause local tissue necrosis and injection site reactions, including erythema, pain, and swelling, in case of extravasation. If extravasation occurs, stop the infusion immediately and manage medically as required. Secondary Malignancies: There is an increased risk of a secondary malignancy with use of Treosulfan. Increased Early Morbidity and Mortality at Dosages Higher than Recommended: Avoid exceeding the recommended dosage of 10 g/m 2 daily for three consecutive days. Embryo-fetal toxicity: Can cause fetal harm. Advise patients of reproductive potential of the potential risk to a fetus and to use effective contraception. Myelosuppression Profound myelosuppression with pancytopenia is the desired therapeutic effect of Treosulfan-based preparative regimens, occurring in all patients. Time to neutrophil counts > Gi/L occurred at a median of 18 days (range 7-42 days) after allogeneic hematopoietic stem cell transplantation in adult patients treated using Treosulfan in combination with fludarabine as the preparative regimen. Do not begin the preparative regimen if the stem cell donor is not available. Monitor blood cell counts daily until hematopoetic recovery. Provide standard supportive care for infections, anemia and thrombocytopenia until there is adequate hematopoietic recovery. Seizures There have been reports of seizures in patients following treatment with treosulfan. Monitor patients for signs of neurological adverse reactions. Clonazepam prophylaxis may be considered for patients at higher risk for seizures, including infants. Skin Disorders An increase of skin disorders (e.g. rash, dermatitis) was observed when patients received sodium bicarbonate-containing hydration in the course of treosulfan infusion, potentially because of acceleration of the pH‑dependent formation of alkylating epoxides. Keep skin clean and dry on days of Treosulfan infusion. Diaper dermatitis may occur because of excretion of treosulfan in the urine. Abridged from the full prescribing information.

The following clinically significant adverse reactions are described elsewhere in the labeling: Myelosuppression Seizures Skin Disorders Injection Site Reactions and Tissue Necrosis Secondary Malignancies The most common adverse reactions (≥20%) are musculoskeletal pain, stomatitis, pyrexia, nausea, edema, infection, and vomiting. Selected Grade 3 or 4 nonhematological laboratory abnormalities are increased GGT, increased bilirubin, increased ALT, increased AST, and increased creatinine. 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 Treosulfan was evaluated in 553 adult patients with AML and MDS in a randomized trial (MC‑FludT.14/L Trial II) comparing Treosulfan 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 Treosulfan (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. Fatal regimen-related adverse reactions occurred within 30 days of transplantation in 1.9% of patients on the Treosulfan arm. All fatalities were due to pulmonary adverse reactions. The most common adverse reactions (≥20%) in patients treated with Treosulfan 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. Table 3 shows the adverse reactions in Study MC‑FludT.14/L Trial II through transplant Day +30. Abridged from the full prescribing information.
