IMPORTANT SAFETY INFORMATION
INDICATION
XROMI is indicated to reduce the frequency of painful crises and reduce the need for blood transfusions in pediatric patients aged 6 months of age to less than 2 years, with sickle cell anemia with recurrent moderate to severe painful crises.
IMPORTANT SAFETY INFORMATION
WARNING: MYELOSUPPRESSION and MALIGNANCIES
- Myelosuppression: XROMI may cause severe myelosuppression. Do not give if bone marrow function is markedly depressed. Monitor blood counts at baseline and throughout treatment. Interrupt treatment and reduce dose as necessary.
- Malignancies: Hydroxyurea is carcinogenic. Advise sun protection and monitor patients for malignancies.
CONTRAINDICATIONS
XROMI is contraindicated in patients who have demonstrated a previous hypersensitivity to hydroxyurea or any other component of its formulation.
WARNINGS AND PRECAUTIONS
Myelosuppression
Hydroxyurea causes severe myelosuppression. Do not initiate treatment with XROMI in patients if bone marrow function is markedly depressed. Bone marrow suppression may occur, and leukopenia is generally its first and most common manifestation. Thrombocytopenia and anemia occur less often and are seldom seen without a preceding leukopenia.
Evaluate hematologic status prior to and during treatment with XROMI. Provide supportive care and modify dose or discontinue XROMI as needed. Recovery from myelosuppression is usually rapid when therapy is interrupted.
Hemolytic Anemia
Cases of hemolytic anemia in patients treated with hydroxyurea for myeloproliferative diseases have been reported. In the setting of confirmed diagnosis of hemolytic anemia and in the absence of other causes, discontinue XROMI. Monitor blood counts throughout treatment.
Malignancies
Hydroxyurea is a human carcinogen. In patients receiving long-term hydroxyurea for myeloproliferative disorders (a condition for which XROMI is not approved), secondary leukemia has been reported.
Secondary leukemia has also been reported in patients treated with long-term hydroxyurea for sickle cell anemia. Leukemia has also been reported in patients with sickle cell anemia and no prior history of treatment with hydroxyurea.
All patients using XROMI should be followed up on a long-term basis with regular blood counts to detect development of leukemia.
Skin cancer has also been reported in patients receiving long-term hydroxyurea. Advise protection from sun exposure and monitor for the development of secondary malignancies.
Embryo-Fetal Toxicity
Based on the mechanism of action and findings in animals, XROMI can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus.
Advise females of reproductive potential to use effective contraception during and after treatment with XROMI for at least 6 months after therapy. Advise males of reproductive potential to use effective contraception during and after treatment with XROMI for at least 6 months after therapy.
Vasculitic Toxicities
Cutaneous vasculitic toxicities, including vasculitic ulcerations and gangrene, have occurred in patients with myeloproliferative disorders during therapy with hydroxyurea. If cutaneous vasculitic ulcers occur, institute treatment and discontinue XROMI.
Live Vaccines
Avoid use of live vaccines in patients taking XROMI as it may potentiate the replication of the virus and/or may increase the adverse reaction of the vaccine because normal defense mechanisms may be suppressed by XROMI. Vaccination with live vaccines in a patient receiving XROMI may result in severe infection. Patient’s antibody response to vaccines may be decreased. Consider consultation with a specialist.
Risks with Concomitant Use of Antiretroviral Drugs
Pancreatitis, hepatotoxicity, and peripheral neuropathy have occurred when hydroxyurea was administered concomitantly with antiretroviral drugs, including didanosine and stavudine.
Macrocytosis
XROMI may cause macrocytosis, which is self-limiting, and is often seen early in the course of treatment. The morphologic change resembles pernicious anemia, but is not related to vitamin B12 or folic acid deficiency. This may mask the diagnosis of pernicious anemia. Prophylactic administration of folic acid is recommended.
Laboratory Test Interference
Interference with uric acid, Urea, or lactic acid assays is possible, rendering falsely elevated results of these in patients treated with hydroxyurea. Hydroxyurea may falsely elevate sensor glucose results from certain continuous glucose monitoring (CGM) systems and may lead to hypoglycemia if sensor glucose results are relied upon to dose insulin.
ADVERSE REACTIONS
Most common adverse reactions (incidence >33%) are neutropenia and thrombocytopenia.
USE IN SPECIFIC POPULATIONS
- Females and Males of Reproductive Potential: XROMI is not approved in males or females of reproductive potential.
- Pediatric Use: Continuous follow-up of the growth of treated children is recommended.
- Renal Impairment: Reduce dosage and closely monitor the hematologic parameters when XROMI is administered to patients with renal impairment who have a creatinine clearance of less than 60mL/min.
- Hepatic Impairment: Close monitoring of hematologic parameters is advised in these patients receiving XROMI.
OVERDOSAGE
Acute mucocutaneous toxicity and neutropenia has been reported in patients receiving hydroxyurea at doses several times above the therapeutic dose. Soreness, violet erythema, oedema on palms and soles followed by scaling of hand and feet, severe generalized hyperpigmentation of the skin and stomatitis have been observed.
Please see complete Prescribing Information including BOXED Warning and Patient Information or at www.xromi.com/pi.
