🩺 Clinical
Arsenic trioxide is used in combination with tretinoin to treat acute promyelocytic leukemia (APL; a type of cancer in which there are too many immature blood cells in the blood and bone marrow) in certain people as a first treatment. It is also used to treat APL in certain people who have not been helped by other types of chemotherapy or whose condition has improved but then worsened following treatment with a retinoid and other types of chemotherapy treatment(s). Arsenic trioxide is in a class of medications called anti-neoplastics. It works by slowing or stopping the growth of cancer cells.

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Arsenic Trioxide Injection is an arsenical indicated: For induction of remission and consolidation in patients with APL who are refractory to, or have relapsed from, retinoid and anthracycline chemotherapy, and whose APL is characterized by the presence of the t(15;17) translocation or PML/RAR-alpha gene expression. ( 1.2 )
1.2Relapsed or Refractory APL Arsenic Trioxide Injection is indicated for induction of remission and consolidation in patients with APL who are refractory to, or have relapsed from, retinoid and anthracycline chemotherapy, and whose APL is characterized by the presence of the t(15;17) translocation or PML/RAR-alpha gene expression.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Relapsed or refractory APL: Induction: Administer 0.15 mg/kg/day intravenously daily until bone marrow remission. Do not exceed 60 days. ( 2.2 ) Consolidation: Administer 0.15 mg/kg/day intravenously daily for 25 doses over a period of up to 5 weeks. ( 2.2 )
2.2Recommended Dosage for Relapsed or Refractory APL A treatment course for patients with relapsed or refractory APL consists of 1 induction cycle and 1 consolidation cycle [see Clinical Studies (14.2)] . For the induction cycle, the recommended dosage of Arsenic Trioxide Injection is 0.15 mg/kg/day intravenously daily until bone marrow remission or up to a maximum of 60 days. For the consolidation cycle, the recommended dosage of Arsenic Trioxide Injection is 0.15 mg/kg/day intravenously daily for 25 doses over a period of up to 5 weeks.
Begin consolidation 3 to 6 weeks after completion of induction cycle.
2.3Monitoring and Dosage Modifications for Adverse Reactions During induction, monitor coagulation studies, blood counts, and chemistries at least 2-3 times per week through recovery. During consolidation, monitor coagulation studies, blood counts, and chemistries at least weekly. Table 2 shows the dosage modifications for adverse reactions due to Arsenic Trioxide Injection when used alone.
Table 2: Dosage Modifications for Adverse Reactions of Arsenic Trioxide Injection Adverse Reaction Dosage Modification Differentiation syndrome, defined by the presence of 2 or more of the following: Unexplained fever Dyspnea Pleural and/or pericardial effusion Pulmonary infiltrates Renal Failure Hypotension Weight gain greater than 5 kg [see Warnings and Precautions ( 5.1 )] Temporarily withhold Arsenic Trioxide Injection. Administer dexamethasone 10 mg intravenously every 12 hours until the resolution of signs and symptoms for a minimum of 3 days.
Resume treatment when the clinical condition improves and reduce the dose of the withheld drug(s) by 50%. Increase the dose of the withheld drug(s) to the recommended dosage after one week in the absence of recurrence of symptoms of differentiation syndrome. If symptoms re-appear, decrease Arsenic Trioxide Injection to the previous dose.
QTc (Framingham formula) Prolongation greater than 450 msec for men or greater than 460 msec for women [see Warnings and Precautions ( 5.2 )] Withhold Arsenic Trioxide Injection and any medication known to prolong the QTc interval. Correct electrolyte abnormalities. After the QTc normalizes and electrolyte abnormalities are corrected, resume treatment with Arsenic Trioxide Injection at a 50% reduced dose (0.075 mg/kg/day daily) for one week after resolution.
If the 50% reduced dose is tolerated for one week (in the absence of QTc prolongation), increase the dose of Arsenic Trioxide Injection to 0.11 mg/kg/day daily for the next week [see Dosage and Administration ( 2.1 )] . The dose of Arsenic Trioxide Injection can be increased to 0.15 mg/kg/day in the absence of QTc prolongation during that 14-day dose-escalation period. Hepatotoxicity, defined by 1 or more of the following: Total bilirubin (TB) greater than 3 times the upper limit of normal (ULN) Aspartate aminotransferase (AST) greater than 5 times the (ULN) Alkaline phosphatase (AP) greater than 5 times the ULN [see Warnings and Precautions ( 5.4 )] Withhold Arsenic Trioxide Injection.
Resume treatment at a 50% reduced dose of the withheld drug(s) when TB is less than 1.5 times the ULN and AP/AST are less than 3 times the ULN. Increase the dose of the withheld drug(s) back to the recommended dosage after one week on the reduced dose in the absence of worsening of hepatotoxicity. Discontinue the withheld drug(s) permanently if hepatotoxicity recurs.
Other severe or life- threatening (grade 3-4) nonhematologic reactions [see Adverse Reactions ( 6 )] Temporarily withhold Arsenic Trioxide Injection. When the adverse reaction resolves to no more than mild (grade 1), resume Arsenic Trioxide Injection reduced by 2 dose levels (…

( 5.6 , 8.1 , 8.3 )
5.1Differentiation Syndrome Differentiation syndrome, which may be life-threatening or fatal, has been observed in patients with acute promyelocytic leukemia (APL) treated with Arsenic Trioxide Injection. In clinical trials, 16-23% of patients treated with Arsenic Trioxide Injection for APL developed differentiation syndrome. Signs and symptoms include unexplained fever, dyspnea, hypoxia, acute respiratory distress, pulmonary infiltrates, pleural or pericardial effusion, weight gain, peripheral edema, hypotension, renal insufficiency, hepatopathy and multi-organ dysfunction.
Differentiation syndrome has been observed with and without concomitant leukocytosis, and it has occurred as early as day 1 of induction to as late as the second month induction therapy. If differentiation syndrome is suspected, temporarily withhold Arsenic Trioxide Injection and immediately initiate dexamethasone 10 mg intravenously every 12 hours and hemodynamic monitoring until resolution of signs and symptoms for a minimum of 3 days [see Dosage and Administration ( 2.3 )] .
5.2Cardiac Conduction Abnormalities Patients treated with Arsenic Trioxide Injection can develop QTc prolongation, torsade de pointes, and complete atrioventricular block. In the clinical trial of patients with relapsed or refractory APL treated with Arsenic Trioxide Injection monotherapy, 40% had at least one ECG tracing with a QTc interval greater than 500 msec. A prolonged QTc was observed between 1 and 5 weeks after start of Arsenic Trioxide Injection infusion, and it usually resolved by 8 weeks after Arsenic Trioxide Injection infusion.
There are no data on the effect of Arsenic Trioxide Injection on the QTc interval during the infusion of the drug. The risk of torsade de pointes is related to the extent of QTc prolongation, concomitant administration of QTc prolonging drugs, a history of torsade de pointes, pre-existing QTc interval prolongation, congestive heart failure, administration of potassium-wasting diuretics, or other conditions that result in hypokalemia or hypomagnesemia. The risk may be increased when Arsenic Trioxide Injection is coadministered with medications that can lead to electrolyte abnormalities (such as diuretics or amphotericin B) [see Drug Interactions ( 7 )] .
Prior to initiating therapy with Arsenic Trioxide Injection, assess the QTc interval by electrocardiogram, correct preexisting electrolyte abnormalities, and consider discontinuing drugs known to prolong QTc interval. Do not administer Arsenic Trioxide Injection to patients with a ventricular arrhythmia or prolonged QTc. If possible, discontinue drugs that are known to prolong the QTc interval.
If it is not possible to discontinue the interacting drug, perform cardiac monitoring frequently [see Drug Interactions ( 7 )] . During Arsenic Trioxide Injection therapy, maintain potassium concentrations above 4 mEq/L and magnesium concentrations above 1.8 mg/dL. Monitor ECG weekly and more frequently for clinically unstable patients.
For patients who develop a QTc Framingham greater than 450 msec for men or greater than 460 msec for women, withhold Arsenic Trioxide Injection and any medication known to prolong the QTc interval. Correct electrolyte abnormalities. When the QTc normalizes and electrolyte abnormalities are corrected, resume Arsenic Trioxide Injection at a reduced dose [see Dosage and Administration ( 2.3 )]…

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Differentiation Syndrome [see Warnings and Precautions ( 5.1 )] Cardiac Conduction Abnormalities [see Warnings and Precautions ( 5.2 )] Encephalopathy [see Warnings and Precautions ( 5.3 )] Hepatotoxicity [see Warnings and Precautions ( 5.4 )] Carcinogenesis [see Warnings and Precautions ( 5.5 )] The most common adverse reactions (>30%) are nausea, cough, fatigue, pyrexia, headache, abdominal pain, vomiting, tachycardia, diarrhea, dyspnea, hypokalemia, leukocytosis, hyperglycemia, hypomagnesemia, insomnia, dermatitis, edema, QTc prolongation, rigors, sore throat, arthralgia, paresthesia, and pruritus ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact at [email protected] or 1-855-642-2594 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical 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. Relapsed or Refractory APL Safety information was available for 52 patients with relapsed or refractory APL who participated in clinical trials of Arsenic Trioxide Injection. Forty patients in the Study PLRXAS01 received the recommended dose of 0.15 mg/kg, of whom 28 completed both induction and consolidation cycles.
An additional 12 patients with relapsed or refractory APL received doses generally similar to the recommended dose. Serious adverse reactions observed in the 40 patients with refractory or relapsed APL enrolled in Study PLRXAS01 included differentiation syndrome (n=3), hyperleukocytosis (n=3), QTc interval ≥ 500 msec (n=16, 1 with torsade de pointes), atrial dysrhythmias (n=2), and hyperglycemia (n=2). The most common adverse reactions (> 30%) were nausea, cough, fatigue, pyrexia, headache, abdominal pain, vomiting, tachycardia, diarrhea, dyspnea, hypokalemia, leukocytosis, hyperglycemia, hypomagnesemia, insomnia, dermatitis, edema, QTc prolongation, rigors, sore throat, arthralgia, paresthesia, and pruritus.
Table 5 describes the adverse reactions in patients aged 5 to 73 years with APL who received Arsenic Trioxide Injection at the recommended dose.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation : Advise women not to breastfeed. ( 8.2 ) R enal Impairment : Monitor patients with severe renal impairment (creatinine clearance less than 30 mL/min) for toxicity when treated with Arsenic Trioxide Injection; dose reduction may be warranted. ( 8.6 ) Hepatic Impairment : Monitor patients with severe hepatic impairment (Child-Pugh Class C) for toxicity when treated with Arsenic Trioxide Injection. ( 8.7 )
8.1Pregnancy Risk Summary Based on the mechanism of action [see Clinical Pharmacology ( 12.1 )] and findings in animal studies, Arsenic Trioxide Injection can cause fetal harm when administered to a pregnant woman. Arsenic trioxide was embryolethal and teratogenic in rats when administered on gestation day 9 at a dose approximately 10 times the recommended human daily dose on a mg/m² basis (see Data ). A related trivalent arsenic, sodium arsenite, produced teratogenicity when administered during gestation in mice at a dose approximately 5 times the projected human dose on a mg/m² basis and in hamsters at an intravenous dose approximately equivalent to the projected human daily dose on a mg/m² basis.
There are no studies with the use of Arsenic Trioxide Injection in pregnant women, and limited published data on arsenic trioxide use during pregnancy are insufficient to inform a drug-associated risk of major birth defects and miscarriage. Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data One patient was reported to deliver a live infant with no reported congenital anomalies after receiving arsenic trioxide during the first five months of pregnancy.
A second patient became pregnant three months after discontinuing arsenic trioxide and was reported to have a normal pregnancy outcome. A third patient was a pregnant healthcare provider who experienced dermal contact with liquid arsenic trioxide and had a normal pregnancy outcome after treatment and monitoring. A fourth patient who became pregnant while receiving arsenic trioxide had a miscarriage.
Animal Data Studies in pregnant mice, rats, hamsters, and primates have shown that inorganic arsenicals cross the placental barrier when given orally or by injection. An increase in resorptions, neural-tube defects, anophthalmia and microphthalmia were observed in rats administered 10 mg/kg of arsenic trioxide on gestation day 9 (approximately 10 times the recommended human daily dose on a mg/m² basis). Similar findings occurred in mice administered a 10 mg/kg dose of a related trivalent arsenic, sodium arsenite (approximately 5 times the projected human dose on a mg/m² basis), on gestation days 6, 7, 8, or 9.
Intravenous injection of 2 mg/kg sodium arsenite (approximately equivalent to the projected human daily dose on a mg/m² basis) on gestation day 7 (the lowest dose tested) resulted in neural-tube defects in hamsters.
8.2Lactation Risk Summary Arsenic trioxide is excreted in human milk. There are no data on the effects of arsenic trioxide on the breastfed child or on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with Arsenic Trioxide Injection and for 2 weeks after the final dose.
8.3Females and Males of Reproductive Potential Arsenic Trioxide Injection can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] .

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and efficacy of Arsenic Trioxide Injection as a single agent for treatment of pediatric patients with relapsed or refractory APL is supported by the pivotal phase 2 study in 40 patients with relapsed or refractory APL. Five patients below the age of 18 years (age range: 5 to 16 years) were treated with Arsenic Trioxide Injection at the recommended dose of 0.15 mg/kg/day. A literature review included an additional 17 patients treated with arsenic trioxide for relapsed or refractory APL, with ages ranging from 4 to 21 years.
No differences in efficacy and safety were observed by age.
🧓 Geriatric Use ▾
8.5Geriatric Use Use of Arsenic Trioxide Injection as monotherapy in patients with relapsed or refractory APL is supported by the openlabel, single-arm trial that included 6 patients aged 65 and older (range: 65 to 73 years). A literature review included an additional 4 patients aged 69 to 72 years who were treated with arsenic trioxide for relapsed or refractory APL. No overall differences in safety or effectiveness were observed between these patients and younger patients.
🆘 Overdosage ▾
10 OVERDOSAGE Manifestations Manifestations of Arsenic Trioxide Injection (arsenic trioxide) overdosage include convulsions, muscle weakness, and confusion. Management For symptoms of Arsenic Trioxide Injection (arsenic trioxide) overdosage, immediately discontinue Arsenic Trioxide Injection and consider chelation therapy. A conventional protocol for acute arsenic intoxication includes dimercaprol administered at a dose of 3 mg/kg intramuscularly every 4 hours until immediate life-threatening toxicity has subsided.
Thereafter, penicillamine at a dose of 250 mg orally, up to a maximum frequency of four times per day (≤ 1 g per day), may be given.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The mechanism of action of Arsenic Trioxide Injection is not completely understood. Arsenic trioxide causes morphological changes and DNA fragmentation characteristic of apoptosis in NB4 human promyelocytic leukemia cells in vitro. Arsenic trioxide also causes damage or degradation of the fusion protein promyelocytic leukemia (PML)-retinoic acid receptor (RAR)-alpha.
12.2Pharmacodynamics Cardiac Electrophysiology In a single-arm trial of Arsenic Trioxide Injection (0.15 mg/kg daily), 16 of 40 patients (40%) had a QTc interval greater than 500 msec. Prolongation of the QTc was observed between 1 and 5 weeks after Arsenic Trioxide Injection infusion, and then returned towards baseline by the end of 8 weeks after Arsenic Trioxide Injection infusion.
12.3Pharmacokinetics The inorganic, lyophilized form of arsenic trioxide, when placed into solution, immediately forms the hydrolysis product arsenious acid (As III ). As III is the pharmacologically active species of arsenic trioxide. Monomethylarsonic acid (MMA V ), and dimethylarsinic acid (DMA V ) are the main pentavalent metabolites formed during metabolism, in addition to arsenic acid (As V ) a product of As III oxidation.
The pharmacokinetics of arsenical species ([As III ], [As V ], [MMA V ], [DMA V ]) were determined in 6 APL patients following once-daily doses of 0.15 mg/kg for 5 days per week. Over the total single-dose range of 7 to 32 mg (administered as 0.15 mg/kg), systemic exposure (AUC) appears to be linear. Peak plasma concentrations of arsenious acid (As III ), the primary active arsenical species were reached at the end of infusion (2 hours).
Plasma concentration of As III declined in a biphasic manner with a mean elimination half-life of 10 to 14 hours and is characterized by an initial rapid distribution phase followed by a slower terminal elimination phase. The daily exposure to As III (mean AUC 0-24h ) was 194 ng·hr/mL (n=5) on Day 1 of Cycle 1 and 332 ng·hr/mL (n=6) on Day 25 of Cycle 1, which represents an approximate 2- fold accumulation. The primary pentavalent metabolites, MMA V and DMA V , are slow to appear in plasma (approximately 10-24 hours after first administration of arsenic trioxide), but, due to their longer half-life, accumulate more upon multiple dosing than does As III .
The mean estimated terminal elimination half-lives of the metabolites MMA V and DMA V are 32 hours and 72 hours, respectively. Approximate accumulation ranged from 1.4- to 8-fold following multiple dosing as compared to single-dose administration. As V is present in plasma only at relatively low levels.
Distribution The volume of distribution (V ss ) for As III is large (mean 562 L, N=10) indicating that As III is widely distributed throughout body tissues. V ss is also dependent on body weight and increases as body weight increases. Elimination Metabolism Much of the As III is distributed to the tissues where it is methylated to the less cytotoxic metabolites, monomethylarsonic acid (MMA V ) and dimethylarsinic acid (DMA V ) by methyltransferases primarily in the liver.
The metabolism of arsenic trioxide also involves oxidation of As III to As V , which may occur in numerous tissues via enzymatic or nonenzymatic processes. As V is present in plasma only at relatively low levels following administration of arsenic trioxide. Excretion Approximately 15% of the administered Arsenic Trioxide Injection dose is excreted in the urine as unchanged As III .
The methylated metabolites of As III (MMA V , DMA V ) are primarily excreted in the urine. The total clearance of As III is 49 L/h and the renal clearance is 9 L/h. Clearance is not dependent on body weight or dose administered over the range of 7-32 mg.
Specific Populations Patients with Renal Impairment The effect of renal impairment on the pharmacokinetics of As III , As V , and the pentavalent metabolites MMA V and DMA V was evaluated in 20 patients with advanced malignancies.…
