Generic Name: Treprostinil Sodium
Class: Vasodilating Agents, Miscellaneous
VA Class: CV900
Vasodilator; a synthetic analog of prostacyclin.2 3 15
Used parenterally (as a continuous sub-Q or IV infusion) for treatment of pulmonary arterial hypertension (PAH) in patients with NYHA class II–IV symptoms to reduce symptoms associated with exercise.1 2 3 Also used parenterally to reduce rate of clinical deterioration in PAH patients who require conversion from epoprostenol therapy; carefully consider risks and benefits of each drug prior to transition.1
Used by oral inhalation to improve walk distance in patients with WHO group I PAH and NYHA class III symptoms.15 16 17 Controlled clinical experience with orally inhaled treprostinil is based primarily on short-term trials in patients receiving the drug as add-on therapy to bosentan or sildenafil.13 15 16 17
Sub-Q or IV treprostinil recommended by the American College of Chest Physicians (ACCP) as one of several options for treatment of PAH in patients with NYHA functional class II, III, or IV disease.12 13 25 Choice of PAH therapy should be individualized; consider factors such as disease severity, route of administration, potential adverse effects, and patient preference.12 13
Designated an orphan drug by FDA for treatment of PAH.31
Administer by continuous sub-Q or IV infusion, or by oral inhalation.1 15
When administered parenterally, sub-Q route generally preferred; reserve IV use for patients who cannot tolerate sub-Q therapy (e.g., due to infusion-site pain or reaction) or in whom risks of IV therapy are considered warranted.1
Administer undiluted drug solution by continuous sub-Q infusion via a self-inserted sub-Q catheter, using a controlled-infusion device (ambulatory infusion pump).1 Consult manufacturer's labeling for pump specifications.1
To avoid potential interruptions in drug delivery, patient must have immediate access to backup infusion pump and sub-Q infusion sets (since abrupt withdrawal or sudden, large dosage reductions may result in worsening of PAH symptoms).1
For sub-Q use, administer as supplied without further dilution.1 A single reservoir (syringe) of undiluted treprostinil may be administered for up to 72 hours at 37°C.1
Calculate sub-Q infusion rates using the following formula:1
sub-Q infusion rate (mL/hr) = [dose (ng/kg per minute) × wt (kg) × 0.00006] ÷ treprostinil dosage strength concentration (mg/mL)
For solution compatibility information, see Compatibility under Stability.
Must be diluted prior to IV administration.1 14 (See Dilution under Dosage and Administration.)
Administer diluted drug solution by continuous IV infusion through a permanent indwelling central venous catheter using a controlled-infusion device (ambulatory infusion pump).1 Consult manufacturer's labeling for pump specifications.1
A peripheral IV catheter (preferably placed in a large vein) may be used temporarily until central venous access can be established.1
To avoid potential interruptions in drug delivery, patient must have immediate access to backup infusion pump and IV infusion sets (since abrupt withdrawal or sudden, large dosage reductions may result in worsening of PAH symptoms).1
Consult manufacturer's labeling for additional information on administration of IV treprostinil.1 14
Must be diluted with sterile water for injection, 0.9% sodium chloride injection, or Flolan sterile diluent for injection prior to IV administration. Diluted solutions are stable at 37°C for ≤48 hours at concentrations as low as 0.004 mg/mL (4000 ng/mL).1
Add appropriate amount of drug to a sufficient volume of diluent to fill pump reservoir (typical IV infusion system reservoirs have a total capacity of 50 or 100 mL).1 Select an infusion rate that will allow for an infusion period of ≤48 hours, and calculate concentration and amount of treprostinil required for the dilution according to the following formulas:1
Diluted IV treprostinil concentration (mg/mL) = [dose (ng/kg per minute) × wt (kg) × 0.00006] ÷ IV infusion rate (mL/hr)
Amount of treprostinil injection (mL) = [diluted IV treprostinil concentration (mg/mL) ÷ treprostinil vial strength (mg/mL)] × total reservoir volume (mL)
Consult manufacturer's labeling for additional information on preparation of IV treprostinil.1
Treprostinil inhalation solution is for oral inhalation only; do not ingest.15
Administer using only the Tyvaso Inhalation System (Optineb-ir Model ON-100/7 device and related accessories).15 Patients should have access to a back-up Optineb-ir device in the event of equipment malfunction.15 Instruct patients on proper administration (including dosing frequency), use, and maintenance of Optineb-ir device.15
Administer 4 times daily during waking hours at equally spaced intervals of approximately 4 hours.15
Prior to first inhalation session, transfer entire contents of a single 2.9-mL ampul of drug into medicine cup supplied by the manufacturer.15 One ampul should contain enough drug for one day of treatment.15 19 After each inhalation session, cap inhalation device and store upright with remaining drug inside for ≤24 hours.15 Discard medicine cup and any unused solution at end of each day and clean Optineb-ir device according to manufacturer's instructions.15
Do not mix with other drugs.15
Do not allow solution to come into contact with the eyes or skin.15
Initially, 1.25 ng/kg per minute.1 If initial dosage is not tolerated, reduce infusion rate to 0.625 ng/kg per minute.1
Adjust dosage to achieve symptomatic improvement while minimizing adverse effects.1 Increase infusion rate based on clinical response in increments of 1.25 ng/kg per minute at weekly intervals for the first 4 weeks and then 2.5 ng/kg per minute at weekly intervals for the remaining duration of the infusion.1
Several months may be required to identify optimal dosage.2 8 14
Initially, 18 mcg (3 inhalations) per treatment session 4 times daily.15 If initial dosage not tolerated, reduce to 1 or 2 inhalations per treatment session, then increase up to 3 inhalations as tolerated.15 Continue to increase dose by 3 inhalations every 1–2 weeks until target maintenance dosage of 54 mcg (9 inhalations) per treatment session attained.15 If unable to titrate to target dosage, maintain patient on highest possible tolerated dosage.15
If a treatment session is missed or interrupted, resume therapy as soon as possible at usual dosage.15
Perform transition in a hospital setting where patient can be closely monitored.1
Initiate treprostinil at a dosage equivalent to 10% of the current epoprostenol dosage; gradually increase treprostinil dosage while simultaneously decreasing dosage of epoprostenol.1 Manufacturer recommends the following titration protocol:1
Step | Epoprostenol Dosage | Treprostinil Dosage |
|---|---|---|
1 | Unchanged | 10% of starting epoprostenol dosage |
2 | 80% of starting epoprostenol dosage | 30% of starting epoprostenol dosage |
3 | 60% of starting epoprostenol dosage | 50% of starting epoprostenol dosage |
4 | 40% of starting epoprostenol dosage | 70% of starting epoprostenol dosage |
5 | 20% of starting epoprostenol dosage | 90% of starting epoprostenol dosage |
6 | 5% of starting epoprostenol dosage | 110% of starting epoprostenol dosage |
7 | 0 | 110% of starting epoprostenol dosage + additional 5–10% increments as needed |
Individually titrate treprostinil dosage to allow transition from epoprostenol therapy while balancing symptoms of PAH and prostacyclin-related adverse effects.1 Manage any increase in PAH symptoms (e.g., shortness of breath) by initially increasing dosage of treprostinil; manage symptoms of excess prostacyclin (e.g., facial flushing, headache, jaw pain) by initially decreasing dosage of epoprostenol.1
Other transition protocols have been used successfully.9 21 22 25 Limited data indicate that patients whose therapy is transitioned from epoprostenol to IV treprostinil appear to require higher average dosages of treprostinil to maintain the same clinical benefits.11 14 21 22 24 25
Limited experience with dosages >40 ng/kg per minute.1
Maximum 54 mcg (9 inhalations) per treatment session 4 times daily.15
In patients with mild to moderate hepatic impairment, decrease initial dosage of sub-Q or IV treprostinil to 0.625 ng/kg per minute (based on ideal body weight).1
Titrate orally inhaled treprostinil slowly in patients with hepatic impairment because of the possibility of increased systemic exposure to the drug.15
Manufacturer makes no specific dosage recommendations for patients with renal impairment;1 titrate dosage slowly because of the possibility of increased systemic exposure to the drug.1 15
Select dosage with caution because of age-related decreases in hepatic, renal, and/or cardiac function and of concomitant disease and drug therapy.1 15
None known.1
Risk of serious and potentially fatal blood stream infections (BSI) and sepsis associated with drug delivery system (chronic indwelling central venous catheter).1 14 25 28 Patients must use strict aseptic technique in routine catheter care and in the preparation and administration of treprostinil.1 Sub-Q route of administration is preferred when the drug is given parenterally.1
Use only under the supervision of a qualified clinician experienced in the diagnosis and management of PAH.1
Initiate therapy in a setting with adequate medical personnel and equipment for providing physiologic monitoring and emergency care.1
Therapy may be continued for prolonged periods; carefully consider patient's ability to administer the drug and care for an infusion system (when drug is given parenterally).1
Safety and efficacy of orally inhaled treprostinil not established in patients with lung disease (i.e., asthma, COPD).15 Monitor patients who develop acute pulmonary infections for any worsening of lung disease and loss of drug effect.15
Avoid abrupt withdrawal or sudden, large dosage reductions; may result in worsening of PAH symptoms.1
Possible increased risk of bleeding, particularly in patients receiving anticoagulant therapy.1 15 (See Specific Drugs under Interactions.)
Risk of symptomatic hypotension in patients with low systemic arterial pressure receiving orally inhaled treprostinil.15
Category B.1 15
Not known whether treprostinil is distributed into milk;1 15 use with caution in nursing women.1 15
Parenteral treprostinil: Safety and efficacy not established in children or adolescents <16 years of age.1 8 Clinical studies did not include sufficient numbers of patients ≤16 years of age to determine whether pediatric patients respond differently than adults.1 Titrate dosage carefully.8
Orally inhaled treprostinil: Safety and efficacy not established in patients <18 years of age.15
Clinical studies did not include sufficient numbers of patients ≥65 years of age to determine whether geriatric patients respond differently than younger patients.1 15
Adjust dosage of sub-Q or IV treprostinil in patients with mild to moderate hepatic impairment.1 (See Hepatic Impairment under Dosage and Administration.)
Not studied in patients with severe hepatic impairment.1 15
Not studied in patients with renal impairment.1 15 However, possibility of reduced renal clearance of the drug in such patients.15

Pharmacologic actions (e.g., vasodilation of pulmonary and systemic arterial vascular beds, inhibition of platelet aggregation) similar to those of epoprostenol.2 3
In animals, vasodilatory effects reduce right and left ventricular afterload and increase cardiac output and stroke volume.1
Causes dose-related negative inotropic and lusitropic effect.1
Orally inhaled treprostinil exhibits high pulmonary selectivity and produces sustained pulmonary vasodilation without substantial systemic effects.18
Modest and temporary effects on QTc interval observed following single oral inhalation doses; possibly an artifact of the rapidly changing heart rate produced by the drug.1 15 Effects of parenteral treprostinil on QTc not studied.1
Importance of advising patient that treprostinil is infused continuously through a self-inserted sub-Q or surgically placed indwelling central venous catheter, via an infusion pump, which will require a long-term commitment on the part of the patient.1
Importance of advising patient to use sterile technique when preparing and administering drug.1
Importance of advising patients that subsequent management of PAH may require therapy with an alternate IV prostacyclin therapy (e.g., epoprostenol).1
Importance of understanding potential risks associated with therapy.1
Importance of patients receiving adequate training in the proper administration and dosing of orally inhaled treprostinil, and on set-up, operation, and maintenance of the Optineb-ir device.15
Importance of having immediate access to a back-up pump and infusion sets (when administered parenterally) or a back-up Optineb-ir device (when administered via oral inhalation) in order to avoid potential interruptions in drug therapy secondary to drug delivery device failure or equipment malfunction.1 15
Importance of advising patients that if a scheduled treatment session of orally inhaled treprostinil is missed, treatment should be resumed as soon as possible.15
Importance of advising patients to avoid skin or eye contact with treprostinil oral inhalation solution.15 If skin or eye contact occurs, instruct patient to immediately rinse the affected area with water.15
Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.1
Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as any concomitant illnesses.1
Importance of informing patients of other important precautionary information.1 (See Cautions.)

WARNING
Melphalan should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. Severe bone marrow suppression with resulting infection or bleeding may occur. Controlled trials comparing intravenous (IV) to oral Melphalan have shown more myelosuppression with the IV formulation. Hypersensitivity reactions, including anaphylaxis, have occured in approximately 2% of patients who received the IV formulation. Melphalan is leukemogenic in humans. Melphalan produces chromosomal aberrations in vitro and in vivo and, therefore, should be considered potentially mutagenic in humans.
Melphalan, also known as L-phenylalanine mustard, phenylalanine mustard, L-PAM, or L-sarcolysin, is a phenylalanine derivative of nitrogen mustard. Melphalan is a bifunctional alkylating agent that is active against selected human neoplastic diseases. It is known chemically as 4-[bis(2-chloroethyl)amino]-L-phenylalanine. The molecular formula is C13H18Cl2N2O2 and the molecular weight is 305.20. The structural formula is:
Melphalan is the active L-isomer of the compound and was first synthesized in 1953 by Bergel and Stock; the D-isomer, known as medphalan, is less active against certain animal tumors, and the dose needed to produce effects on chromosomes is larger than that required with the L-isomer. The racemic (DL-) form is known as merphalan or sarcolysin.
Melphalan is practically insoluble in water and has a pKa1 of~2.5.
Melphalan Hydrochloride for Injection is supplied as a sterile, nonpyrogenic, freeze-dried powder. Each single-use vial contains Melphalan hydrochloride equivalent to 50 mg Melphalan and the inactive ingredient povidone 20 mg. Melphalan Hydrochloride for Injection is reconstituted using the sterile diluent provided. Each vial of sterile diluent contains sodium citrate 0.2 g, propylene glycol 6.0 mL, ethanol (96%) 0.52 mL, and Water for Injection to a total of 10 mL. Melphalan Hydrochloride for Injection is administered intravenously.
Melphalan is an alkylating agent of the bischloroethylamine type. As a result, its cytotoxicity appears to be related to the extent of its interstrand cross-linking with DNA, probably by binding at the N7 position of guanine. Like other bifunctional alkylating agents, it is active against both resting and rapidly dividing tumor cells.
The pharmacokinetics of Melphalan after IV administration has been extensively studied in adult patients. Following injection, drug plasma concentrations declined rapidly in a biexponential manner with distribution phase and terminal elimination phase half-lives of approximately 10 and 75 minutes, respectively. Estimates of average total body clearance varied among studies, but typical values of approximately 7 to 9 mL/min/kg (250 to 325 mL/min/m2) were observed. One study has reported that on repeat dosing of 0.5 mg/kg every 6 weeks, the clearance of Melphalan decreased from 8.1 mL/min/kg after the first course, to 5.5 mL/min/kg after the third course, but did not decrease appreciably after the third course. Mean (±SD) peak Melphalan plasma concentrations in myeloma patients given IV Melphalan at doses of 10 or 20 mg/m2 were 1.2 ± 0.4 and 2.8 ± 1.9 mcg/mL, respectively.
The steady-state volume of distribution of Melphalan is 0.5 L/kg. Penetration into cerebrospinal fluid (CSF) is low. The extent of Melphalan binding to plasma proteins ranges from 60% to 90%. Serum albumin is the major binding protein, while α 1-acid glycoprotein appears to account for about 20% of the plasma protein binding. Approximately 30% of the drug is (covalently) irreversibly bound to plasma proteins. Interactions with immunoglobulins have been found to be negligible.
Melphalan is eliminated from plasma primarily by chemical hydrolysis to monohydroxyMelphalan and dihydroxyMelphalan. Aside from these hydrolysis products, no other Melphalan metabolites have been observed in humans. Although the contribution of renal elimination to Melphalan clearance appears to be low, one study noted an increase in the occurrence of severe leukopenia in patients with elevated BUN after 10 weeks of therapy.
A randomized trial compared prednisone plus IV Melphalan to prednisone plus oral Melphalan in the treatment of myeloma. As discussed below, overall response rates at week 22 were comparable; however, because of changes in trial design, conclusions as to the relative activity of the 2 formulations after week 22 are impossible to make.
Both arms received oral prednisone starting at 0.8 mg/kg/day with doses tapered over 6 weeks. Melphalan doses in each arm were:
Arm 1 Oral Melphalan 0.15 mg/kg/day × 7 followed by 0.05 mg/kg/day when WBC began to rise.
Arm 2 IV Melphalan 16 mg/m2 q 2 weeks × 4 (over 6 weeks) followed by the same dose every 4 weeks.
Doses of Melphalan were adjusted according to the following criteria:
| WBC/mm3 | Platelets | Percent of Full Dose |
| ≥4,000 | ≥100,000 | 100 |
| ≥3,000 | ≥75,000 | 75 |
| ≥2,000 | ≥50,000 | 50 |
| <2,000 | <50,000 | 0 |
One hundred seven patients were randomized to the oral Melphalan arm and 203 patients to the IV Melphalan arm. More patients had a poor-risk classification (58% versus 44%) and high tumor load (51% versus 34%) on the oral compared to the IV arm (P<0.04).
Response rates at week 22 are shown in the following table:
| Initial Arm | Evaluable Patients | Responders n (%) | P |
| Oral Melphalan | 100 | 44 (44%) | P>0.2 |
| IV Melphalan | 195 | 74 (38%) |
Because of changes in protocol design after week 22, other efficacy parameters such as response duration and survival cannot be compared.
Severe myelotoxicity (WBC ≤1,000 and/or platelets ≤25,000) was more common in the IV Melphalan arm (28%) than in the oral Melphalan arm (11%).
An association was noted between poor renal function and myelosuppression; consequently, an amendment to the protocol required a 50% reduction in IV Melphalan dose if the BUN was ≥30 mg/dL. The rate of severe leukopenia in the IV arm in the patients with BUN over 30 mg/dL decreased from 50% (8/16) before protocol amendment to 11% (3/28) (P = 0.01) after the amendment.
Before the dosing amendment, there was a 10% (8/77) incidence of drug-related death in the IV arm. After the dosing amendment, this incidence was 3% (3/108). This compares to an overall 1% (1/100) incidence of drug-related death in the oral arm.
Melphalan Hydrochloride for Injection is indicated for the palliative treatment of patients with multiple myeloma for whom oral therapy is not appropriate.
Melphalan should not be used in patients whose disease has demonstrated prior resistance to this agent. Patients who have demonstrated hypersensitivity to Melphalan should not be given the drug.
Melphalan Hydrochloride for Injection may cause local tissue damage should extravasation occur, and consequently it should not be administered by direct injection into a peripheral vein. It is recommended that Melphalan Hydrochloride for Injection be administered by injecting slowly into a fast-running IV infusion via an injection port, or via a central venous line (see DOSAGE AND ADMINISTRATION: Administration Precautions).
Melphalan should be administered in carefully adjusted dosage by or under the supervision of experienced physicians who are familiar with the drug's actions and the possible complications of its use.
As with other nitrogen mustard drugs, excessive dosage will produce marked bone marrow suppression. Bone marrow suppression is the most significant toxicity associated with Melphalan Hydrochloride for Injection in most patients. Therefore, the following tests should be performed at the start of therapy and prior to each subsequent dose of Melphalan Hydrochloride: platelet count, hemoglobin, white blood cell count, and differential. Thrombocytopenia and/or leukopenia are indications to withhold further therapy until the blood counts have sufficiently recovered. Frequent blood counts are essential to determine optimal dosage and to avoid toxicity. Dose adjustment on the basis of blood counts at the nadir and day of treatment should be considered.
Hypersensitivity reactions including anaphylaxis have occurred in approximately 2% of patients who received the IV formulation (see ADVERSE REACTIONS). These reactions usually occur after multiple courses of treatment. Treatment is symptomatic. The infusion should be terminated immediately, followed by the administration of volume expanders, pressor agents, corticosteroids, or antihistamines at the discretion of the physician. If a hypersensitivity reaction occurs, IV or oral Melphalan should not be readministered since hypersensitivity reactions have also been reported with oral Melphalan.
Secondary malignancies, including acute nonlymphocytic leukemia, myeloproliferative syndrome, and carcinoma, have been reported in patients with cancer treated with alkylating agents (including Melphalan). Some patients also received other chemotherapeutic agents or radiation therapy. Precise quantitation of the risk of acute leukemia, myeloproliferative syndrome, or carcinoma is not possible. Published reports of leukemia in patients who have received Melphalan (and other alkylating agents) suggest that the risk of leukemogenesis increases with chronicity of treatment and with cumulative dose. In one study, the 10-year cumulative risk of developing acute leukemia or myeloproliferative syndrome after oral Melphalan therapy was 19.5% for cumulative doses ranging from 730 to 9,652 mg. In this same study, as well as in an additional study, the 10-year cumulative risk of developing acute leukemia or myeloproliferative syndrome after oral Melphalan therapy was less than 2% for cumulative doses under 600 mg. This does not mean that there is a cumulative dose below which there is no risk of the induction of secondary malignancy. The potential benefits from Melphalan therapy must be weighed on an individual basis against the possible risk of the induction of a second malignancy.
Adequate and well-controlled carcinogenicity studies have not been conducted in animals. However, intraperitoneal (IP) administration of Melphalan in rats (5.4 to 10.8 mg/m2) and in mice (2.25 to 4.5 mg/m2) 3 times per week for 6 months followed by 12 months post-dose observation produced peritoneal sarcoma and lung tumors, respectively.
Melphalan has been shown to cause chromatid or chromosome damage in humans. Intramuscular administration of Melphalan at 6 and 60 mg/m2 produced structural aberrations of the chromatid and chromosomes in bone marrow cells of Wistar rats.
Melphalan causes suppression of ovarian function in premenopausal women, resulting in amenorrhea in a significant number of patients. Reversible and irreversible testicular suppression have also been reported.
Melphalan may cause fetal harm when administered to a pregnant woman. While adequate animal studies have not been conducted with IV Melphalan, oral (6 to 18 mg/m2/day for 10 days) and IP (18 mg/m2) administration in rats was embryolethal and teratogenic. Malformations resulting from Melphalan included alterations of the brain (underdevelopment, deformation, meningocele, and encephalocele) and eye (anophthalmia and microphthalmos), reduction of the mandible and tail, as well as hepatocele (exomphaly). There are no adequate and well-controlled studies in pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant.
In all instances where the use of Melphalan Hydrochloride for Injection is considered for chemotherapy, the physician must evaluate the need and usefulness of the drug against the risk of adverse events. Melphalan should be used with extreme caution in patients whose bone marrow reserve may have been compromised by prior irradiation or chemotherapy or whose marrow function is recovering from previous cytotoxic therapy.
Dose reduction should be considered in patients with renal insufficiency receiving IV Melphalan. In one trial, increased bone marrow suppression was observed in patients with BUN levels ≥30 mg/dL. A 50% reduction in the IV Melphalan dose decreased the incidence of severe bone marrow suppression in the latter portion of this study.
Administration of live vaccines to immunocompromised patients should be avoided.
Patients should be informed that the major acute toxicities of Melphalan are related to bone marrow suppression, hypersensitivity reactions, gastrointestinal toxicity, and pulmonary toxicity. The major long-term toxicities are related to infertility and secondary malignancies. Patients should never be allowed to take the drug without close medical supervision and should be advised to consult their physicians if they experience skin rash, signs or symptoms of vasculitis, bleeding, fever, persistent cough, nausea, vomiting, amenorrhea, weight loss, or unusual lumps/masses. Women of childbearing potential should be advised to avoid becoming pregnant.
Periodic complete blood counts with differentials should be performed during the course of treatment with Melphalan. At least 1 determination should be obtained prior to each dose. Patients should be observed closely for consequences of bone marrow suppression, which include severe infections, bleeding, and symptomatic anemia (see WARNINGS).
The development of severe renal failure has been reported in patients treated with a single dose of IV Melphalan followed by standard oral doses of cyclosporine. Cisplatin may affect Melphalan kinetics by inducing renal dysfunction and subsequently altering Melphalan clearance. IV Melphalan may also reduce the threshold for BCNU lung toxicity. When nalidixic acid and IV Melphalan are given simultaneously, the incidence of severe hemorrhagic necrotic enterocolitis has been reported to increase in pediatric patients.
See WARNINGS section.

It is not known whether this drug is excreted in human milk. IV Melphalan should not be given to nursing mothers.
The safety and effectiveness in pediatric patients have not been established.
Clinical studies of Melphalan Hydrochloride for Injection did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
(SEE OVERDOSAGE)
The following information on adverse reactions is based on data from both oral and IV administration of Melphalan as a single agent, using several different dose schedules for treatment of a wide variety of malignancies.
The most common side effect is bone marrow suppression leading to leukopenia, thrombocytopenia, and anemia. White blood cell count and platelet count nadirs usually occur 2 to 3 weeks after treatment, with recovery in 4 to 5 weeks after treatment. Irreversible bone marrow failure has been reported.
Gastrointestinal disturbances such as nausea and vomiting, diarrhea, and oral ulceration occur infrequently. Hepatic disorders ranging from abnormal liver function tests to clinical manifestations such as hepatitis and jaundice have been reported. Hepatic veno-occlusive disease has been reported.
Acute hypersensitivity reactions including anaphylaxis were reported in 2.4% of 425 patients receiving Melphalan Hydrochloride for Injection for myeloma (see WARNINGS). These reactions were characterized by urticaria, pruritus, edema, skin rashes, and in some patients, tachycardia, bronchospasm, dyspnea, and hypotension. These patients appeared to respond to antihistamine and corticosteroid therapy. If a hypersensitivity reaction occurs, IV or oral Melphalan should not be readministered since hypersensitivity reactions have also been reported with oral Melphalan. Cardiac arrest has also been reported rarely in association with such reports.
Other reported adverse reactions include skin hypersensitivity, skin ulceration at injection site, skin necrosis rarely requiring skin grafting, maculopapular rashes, vasculitis, alopecia, hemolytic anemia, allergic reaction, pulmonary fibrosis (including fatal outcomes), and interstitial pneumonitis. Temporary significant elevation of the blood urea has been seen in the early stages of therapy in patients with renal damage. Subjective and transient sensation of warmth and/or tingling.
Overdoses resulting in death have been reported. Overdoses, including doses up to 290 mg/m2, have produced the following symptoms: severe nausea and vomiting, decreased consciousness, convulsions, muscular paralysis, and cholinomimetic effects. Severe mucositis, stomatitis, colitis, diarrhea, and hemorrhage of the gastrointestinal tract occur at high doses (>100 mg/m2). Elevations in liver enzymes and veno-occlusive disease occur infrequently. Significant hyponatremia caused by an associated inappropriate secretion of ADH syndrome has been observed. Nephrotoxicity and adult respiratory distress syndrome have been reported rarely. The principal toxic effect is bone marrow suppression. Hematologic parameters should be closely followed for 3 to 6 weeks. An uncontrolled study suggests that administration of autologous bone marrow or hematopoietic growth factors (i.e., sargramostim, filgrastim) may shorten the period of pancytopenia. General supportive measures together with appropriate blood transfusions and antibiotics should be instituted as deemed necessary by the physician. This drug is not removed from plasma to any significant degree by hemodialysis or hemoperfusion. A pediatric patient survived a 254-mg/m2 overdose treated with standard supportive care.
The usual IV dose is 16 mg/m2. Dosage reduction of up to 50% should be considered in patients with renal insufficiency (BUN ≥30 mg/dL) (see PRECAUTIONS: General). The drug is administered as a single infusion over 15 to 20 minutes. Melphalan is administered at 2-week intervals for 4 doses, then, after adequate recovery from toxicity, at 4-week intervals. Available evidence suggests about one third to one half of the patients with multiple myeloma show a favorable response to the drug. Experience with oral Melphalan suggests that repeated courses should be given since improvement may continue slowly over many months, and the maximum benefit may be missed if treatment is abandoned prematurely. Dose adjustment on the basis of blood cell counts at the nadir and day of treatment should be considered.
As with other toxic compounds, caution should be exercised in handling and preparing the solution of Melphalan Hydrochloride. Skin reactions associated with accidental exposure may occur. The use of gloves is recommended. If the solution of Melphalan Hydrochloride contacts the skin or mucosa, immediately wash the skin or mucosa thoroughly with soap and water.
Procedures for proper handling and disposal of anticancer drugs should be considered. Several guidelines on this subject have been published. 1-8 There is no general agreement that all of the procedures recommended in the guidelines are necessary or appropriate.
Parenteral drug products should be visually inspected for particulate matter and discoloration prior to administration whenever solution and container permit. If either occurs, do not use this product.
Care should be taken to avoid possible extravasation of Melphalan and in cases of poor peripheral venous access, consideration should be given to use of a central venous line (see WARNINGS).
The time between reconstitution/dilution and administration of Melphalan Hydrochloride for Injection should be kept to a minimum because reconstituted and diluted solutions of Melphalan Hydrochloride for Injection are unstable. Over as short a time as 30 minutes, a citrate derivative of Melphalan has been detected in reconstituted material from the reaction of Melphalan Hydrochloride with Sterile Diluent for Melphalan Hydrochloride for Injection. Upon further dilution with saline, nearly 1% label strength of Melphalan hydrolyzes every 10 minutes.
A precipitate forms if the reconstituted solution is stored at 5°C. DO NOT REFRIGERATE THE RECONSTITUTED PRODUCT.
Melphalan Hydrochloride for Injection is supplied in a carton containing one single-use clear glass vial of freeze-dried Melphalan hydrochloride equivalent to 50 mg Melphalan and one 10-mL clear glass vial of sterile diluent.
