【商品名称】
通用名称: 马发兰
品牌名称:Alphalan
通用英文名称:Melphalan
其他名称:爱克兰片、美法仑片、Alkeran, 左旋苯丙氨酸氮芥,L-Sarcolysin,L-PAM。
【成分】
本品主要成分为马发兰左旋体苯丙按酸氮芥
化学名:L-3{对[双(2-氯乙基)胺基]苯基}丙氨酸。
分子式:C13H18O2N2Cl2。
分子量:305.20克/摩尔。
【适应症/功能主治】
适用于治疗多发性骨髓瘤及晚期卵巢腺癌,在单一及联合化疗中是多发性骨髓瘤的首选药物。马法兰单独应用或与其他药物合用,对于部分晚期乳腺癌病人有显著疗效。
【规格型号】2mg片剂*25片
【用法用量】
因为马法兰具有骨髓抑制作用,故在治疗期间内,必需频繁监测血象(血细胞计数),必要时暂缓用药或调整剂量。成年口服用药:口服马发兰的吸收是易变的,为了确保达到可能的治疗水平。应谨慎增加剂量,直到出现出现骨髓抑制作用为止。
多发性骨髓瘤:
通常的口服剂量是每天6毫克(3片)。整个日剂量可以一次给予。根据每周进行的血细胞计数调整剂量。治疗2〜3周后,应停药4周,在此期间仔细观察血细胞计数。当白血球和血小板计数上升时,可以每天维持2毫克的剂量。由于口服药物后马发兰的血浆水平因人而异,建议ALKERAN的剂量应谨慎得加量,直到观察到骨髓抑制,以确保药物的潜在治疗水平已经达到。
当白细胞计数大于4,000个细胞/ mcL,血小板计数大于100,000个细胞/ mcL时,建立2mg /天的持续维持治疗。根据血液学反应,将剂量调整至1至3mg /天。希望保持显着程度的骨髓抑制,以保持白细胞计数在3,000至3,500细胞/ mcL的范围内。 Hoogstraten等人开始用0.15mg / kg /天进行治疗7天。其后休息至少14天,但可能长达5至6周。当白血球和血小板计数升高时开始维持治疗。维持剂量为0.05mg / kg /天或更少,并根据血液计数进行调整。有证据表明,大约三分之一到一半的多发性骨髓瘤患者对口服药物有良好的反应。
Alexanian等人的一项研究表明,ALKERAN与强的松组合的使用显着提高了多发性骨髓瘤患者达到缓解的百分比。一个方案是以0.25mg / kg /天连续连续4天(或连续5天为0.20mg / kg /天)施用ALKERAN疗程,总剂量为1mg / kg /疗程。如果粒细胞计数和血小板计数恢复正常水平,则每4至6周重复4至5天的疗程。要强调的是,反应可能在很多个月内是非常缓慢的;重要的是重复的疗程或连续治疗,因为改善可能会持续缓慢的多个月,如果治疗被放弃太早,可能会错过最大的好处。在中度至重度肾损伤的患者中,目前可获得的药代动力学数据不能证明对这些患者减少剂量的绝对推荐,但是最初使用降低剂量可能是谨慎的。
上皮性卵巢癌:一种常用的治疗卵巢癌的方案是以每日0.2mg / kg的剂量连用5天。 每4~8周或当外周血象恢复时重复疗程;当出现骨髓毒性时应减低剂量。
晚期乳腺癌:口服每日每公斤体重0.15毫克或每平方米体表面积6毫克,共5日,每六周重复疗程,也可使用美法仑静脉注射治疗。
真性红血球增多症:诱导缓解期,每日用6~10毫克共5~7天,之后可每日2~4毫克直至能满意地控制症状,维持剂量可每周一次用2~6毫克,其间必须对患者仔细谨慎地进行血液学控制,以血细胞计数结果为依据,适当调整剂量。
肾功能不全患者:依据目前建立的药动学数据,对中度至重度肾功能不全患者口服马法兰,并非绝对推荐降低剂量,但起始剂量需谨慎地降低。
【不良反应】
骨髓抑制:为剂量限制性毒性,主要表现为白细胞、血小板减少及贫血,白细胞减少可在首次用药后的第2周至第3周出现;有时老年患者骨髓抑制可延续5~6周
胃肠道反应:大剂量一次用药可出现恶心、呕吐,小剂量持续给药则不明显。
长期持续给药,偶可引起白血病、脱皮、皮炎、口炎及肺纤维化。
【禁忌】
孕妇、哺乳妇禁用。
近期内用过化疗或放疗而白细胞减少者不宜使用。
肾功能不良者慎用。
【注意事项】
每次用药前须检查血像,嗜中性白细胞低于2×109/L时应停药。
应根据骨髓抑制程度调整剂量。

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 occurred 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.
Alkeran Description
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.
Alkeran for Injection is supplied as a sterile, nonpyrogenic, freeze-dried powder. Each single-use vial contains melphalan hydrochloride equivalent to 50 mg melphalan and 20 mg povidone. Alkeran 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. Alkeran for Injection is administered intravenously.
Alkeran - Clinical Pharmacology
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.
Pharmacokinetics
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 average melphalan binding to plasma proteins is highly variable (range: 53% to 92%). Serum albumin is the major binding protein, accounting for approximately 40% to 60% of the plasma protein binding, while α1-acid glycoprotein accounts for about 20% of the plasma protein binding. Approximately 30% of melphalan 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.
Clinical Trial
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 x 7 followed by 0.05 mg/kg/day when WBC began to rise.
Arm 2: IV melphalan 16 mg/m2 q 2 weeks x 4 (over 6 weeks) followed by the same dose every 4 weeks.
Doses of melphalan were adjusted according to the following criteria:

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:

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.
Indications and Usage for Alkeran
Alkeran for Injection is indicated for the palliative treatment of patients with multiple myeloma for whom oral therapy is not appropriate.
Contraindications
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.
Warnings
Alkeran 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 Alkeran 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 Alkeran for Injection in most patients. Therefore, the following tests should be performed at the start of therapy and prior to each subsequent dose of Alkeran: 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.
Carcinogenesis
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.
Mutagenesis
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.
Impairment of Fertility
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.
Pregnancy
Pregnancy Category D. 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.
Precautions
General
In all instances where the use of Alkeran 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.
Information for Patients
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.
Laboratory Tests
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).
Drug Interactions
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.
Carcinogenesis, Mutagenesis, Impairment of Fertility
See WARNINGS section.
Pregnancy
Teratogenic Effects
Pregnancy Category D: See WARNINGS section.
Nursing Mothers
It is not known whether this drug is excreted in human milk. IV melphalan should not be given to nursing mothers.
Pediatric Use
The safety and effectiveness in pediatric patients have not been established.
Geriatric Use
Clinical studies of Alkeran 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.
ADVERSE REACTIONS (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.
Hematologic
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
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.
Hypersensitivity
Acute hypersensitivity reactions including anaphylaxis were reported in 2.4% of 425 patients receiving Alkeran 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.
Miscellaneous
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.
Overdosage
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.
Alkeran Dosage and Administration
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.
Administration Precautions
As with other toxic compounds, caution should be exercised in handling and preparing the solution of Alkeran. Skin reactions associated with accidental exposure may occur. The use of gloves is recommended. If the solution of Alkeran 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.1-4 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).
Preparation for Administration/Stability
1.
Alkeran for Injection must be reconstituted by rapidly injecting 10 mL of the supplied diluent directly into the vial of lyophilized powder using a sterile needle (20-gauge or larger needle diameter) and syringe. Immediately shake vial vigorously until a clear solution is obtained. This provides a 5-mg/mL solution of melphalan. Rapid addition of the diluent followed by immediate vigorous shaking is important for proper dissolution.
2.
Immediately dilute the dose to be administered in 0.9% Sodium Chloride Injection, USP, to a concentration not greater than 0.45 mg/mL.
3.
Administer the diluted product over a minimum of 15 minutes.
4.
Complete administration within 60 minutes of reconstitution.
The time between reconstitution/dilution and administration of Alkeran should be kept to a minimum because reconstituted and diluted solutions of Alkeran 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 Alkeran with Sterile Diluent for Alkeran. 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.
How is Alkeran Supplied
Alkeran 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 (NDC 52609-3001-0).
Store at controlled room temperature 15° to 30°C (59° to 86°F) and protect from light.
