Melphalan injection is used to treat multiple myeloma (a type of cancer of the bone marrow) in people who are unable to take melphalan by mouth. Melphalan injection is also used to destroy bone marrow and cancer cells in preparation for a bone marrow transplant in people with multiple myeloma. Melphalan is in a class of medications called alkylating agents. It works by stopping or slowing the growth of cancer cells in your body.

⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE HEPZATO for injection, as a component of the HEPZATO KIT, is indicated as a liver-directed treatment for adult patients with uveal melanoma with unresectable hepatic metastases affecting less than 50% of the liver and no extrahepatic disease or extrahepatic disease limited to the bone, lymph nodes, subcutaneous tissues, or lung that is amenable to resection or radiation. HEPZATO is an alkylating drug indicated as a liver-directed treatment for adult patients with uveal melanoma with unresectable hepatic metastases affecting less than 50% of the liver and no extrahepatic disease, or extrahepatic disease limited to the bone, lymph nodes, subcutaneous tissues, or lung that is amenable to resection or radiation.( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION HEPZATO, a component of the HEPZATO KIT, is administered by intra-arterial infusion into the hepatic artery (see instructions for use [IFU]). The recommended dose is 3 mg/kg based on ideal body weight (see Table 1 ), with a maximum absolute dose of 220 mg during a single HEPZATO treatment. ( 2.2 ).
The drug is infused over 30 minutes followed by a 30-minute washout period (see IFU). Treatments should be administered every six (6) to eight (8) weeks but can be delayed until recovery from toxicities and as per clinical judgement. ( 2.3 )
2.1Important Pre-Treatment and Administration Information HEPZATO is a component of the HEPZATO KIT Hepatic Delivery System [HDS]. Refer to the HEPZATO KIT Hepatic Delivery System Instructions for Use (IFU) for additional instructions including pre-infusion evaluation, hydration, premedication, anticoagulation, and supportive care. Caution: The double balloon catheter component of the HDS contains natural rubber latex which may cause allergic reactions [see Contraindications ( 4 ) ].
Healthcare providers must complete the required HEPZATO KIT REMS training prior to administration of the HEPZATO KIT [see Warnings and Precautions ( 5.2 )]. Discontinue oral anticoagulation and drugs affecting platelet function prior to the procedure [see Warnings and Precautions ( 5.1 )]. Discontinue ACE-inhibitors, calcium channel blockers, or alpha-1-adrenergic blockers prior to the procedure [see Warnings and Precautions ( 5.1 )].
Conduct baseline hematologic testing. Administer intra-hepatic HEPZATO with the HEPZATO KIT only to patients with the following [see Warnings and Precautions ( 5.3 )]. Hemoglobin ≥ 10 g/dL Platelets ≥ 100,000/microliter Neutrophils > 2000/microliter
2.2Recommended Dosage Administer HEPZATO via the HEPZATO KIT Hepatic Delivery System only to patients weighing 35 kg or greater due to potential size limitations with respect to percutaneous catheterization. HEPZATO, a component of the HEPZATO KIT, is administered by infusion into the hepatic artery (see IFU) every 6 to 8 weeks for up to 6 total infusions. The recommended HEPZATO dose is 3 mg/kg based on ideal body weight (IBW), as calculated per Table 1 below, with a maximum of 220 mg during a single treatment.
Table 1: Calculation of IBW for HEPZATO Dosing Height Ideal Body Weight Men ≥ 152 cm 52 kg + (0.75 kg/cm of height greater than 152 cm) < 152 cm 52 kg – (0.75 kg/cm of height less than 152 cm) Women ≥ 152 cm 49 kg + (0.67 kg/cm of height greater than 152 cm) < 152 cm 49 kg – (0.67 kg/cm of height less than 152 cm)
2.3Dosage Modifications for Adverse Reactions A dosage reduction to 2 mg/kg is recommended for subsequent treatments for the following reasons: Grade 4 neutropenia of > 5 days duration despite growth factor support or associated with neutropenic fever; Grade 4 thrombocytopenia of > 5 days duration or associated with a hemorrhage that required a transfusion; HEPZATO administered with the HEPZATO KIT should be discontinued if patients have life threatening or HEPZATO-related persistent toxicity that has not resolved to Grade 2 or less by 8 weeks following treatment.
2.4Preparation and Administration Refer to the HEPZATO KIT Hepatic Delivery System IFU for further details and instructions. Reconstitute and dilute melphalan immediately prior to beginning intra-arterial infusion. Reconstituted and diluted solutions of HEPZATO are unstable.
No more than 60 minutes should elapse from reconstitution and completion of the intra-hepatic infusion of the diluted HEPZATO solution. A citrate derivative of melphalan has been detected in reconstituted HEPZATO in 30 minutes, and nearly 1% of labeled strength of melphalan hydrolyzes every 10 minutes when reconstituted HEPZATO is further diluted in 0.9% Sodium Chloride. A precipitate forms if the reconstituted solution is stored at 5°C.
Do not refrigerate HEPZATO once reconstituted. HEPZATO is a hazardous drug 1 . Follow applicable special handling and disposa…

⛔ Contraindications ▾
4 CONTRAINDICATIONS HEPZATO and the HEPZATO KIT are contraindicated in patients with: Active intracranial metastases or brain lesions with a propensity to bleed Liver failure, portal hypertension, or known varices at risk for bleeding Surgery or medical treatment of the liver in the previous 4 weeks Uncorrectable coagulopathy Inability to safely undergo general anesthesia, including active cardiac conditions including, but not limited to, unstable coronary syndromes (unstable or severe angina or myocardial infarction), worsening or new-onset congestive heart failure, significant arrhythmias, or severe valvular disease History of allergies or known hypersensitivity to melphalan History of allergies or known hypersensitivity to a component or material utilized within the HEPZATO KIT including History of allergy to natural rubber latex History of allergy or hypersensitivity to heparin or presence of heparin-induced thrombocytopenia (HIT) History of severe allergic reaction to iodinated contrast not controlled by premedication with antihistamines and steroids Active intracranial metastases or brain lesions with a propensity to bleed Liver failure, portal hypertension, or known varices at risk for bleeding Surgery or medical treatment of the liver in the previous 4 weeks Active cardiac conditions including, but not limited to, unstable coronary syndromes (unstable or severe angina or myocardial infarction), worsening or new-onset congestive heart failure, significant arrhythmias, or severe valvular disease History of allergies or known hypersensitivity to melphalan or a component or material utilized within the HEPZATO KIT including natural rubber latex, heparin, and severe hypersensitivity to iodinated contrast not controlled by antihistamines and steroids ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypersensitivity reactions, including anaphylaxis, have occurred in patients who received an intravenous (IV) formulation of melphalan. Immediately terminate hepatic arterial melphalan infusion for hypersensitivity reactions and administer supportive care. ( 5.4 ) Gastrointestinal disturbances such as nausea and vomiting, abdominal pain and diarrhea are common.
( 5.5 ) Carcinogenic/Mutagenic effects: Secondary malignancies, including acute nonlymphocytic leukemia, myeloproliferative syndrome, and carcinoma, have been reported in patients with cancer treated with alkylating drugs (including melphalan). Melphalan has been shown to cause chromatid or chromosome damage in humans. ( 5.6 ) Embryo-fetal toxicity: Can cause fetal harm.
Advise females of reproductive potential and males with female partners of reproductive potential of the potential risk to a fetus and to use effective contraception. ( 5.7 , 8.1 , 8.3 ) Infertility: Melphalan-based chemotherapy regimens have been reported to cause suppression of ovarian function in premenopausal women and testicular suppression in men. ( 5.8 )
5.1Peri-Procedural Complications Hemorrhage, hepatocellular injury, and thromboembolic events have been observed when HEPZATO has been administered via hepatic intra-arterial administration. Administration of HEPZATO requires general anesthesia and extracorporeal bypass of circulation which may cause life threatening or fatal adverse effects. Ensure the patient is euvolemic but do not overhydrate the patient.
Monitor for these peri-procedural complications during the procedure and for at least 72 hours following the procedure. To mitigate the risk of thromboembolic events, administer anticoagulation as described in the IFU during the procedure. Due to the risk of bleeding, do not use in patients with uncorrectable coagulopathies and delay treatment with the HEPZATO KIT for at least 4 weeks after surgery or other medical procedure involving the liver.
Platelets and clotting factors may be removed during the HEPZATO KIT procedure. Monitor platelets and coagulation parameters as described in the IFU. If life-threatening bleeding occurs during the procedure, reverse anticoagulation as described in the IFU and correct coagulopathy as appropriate.
Discontinue anticoagulation with warfarin or other oral anticoagulants prior to the procedure; resume when hemostasis has been restored after the procedure, provided no bleeding complications have been observed. Refer to the Prescribing Information of the anticoagulant agent for bridging recommendations for anti-coagulation prior to surgical procedures. Discontinue drugs affecting platelet function such as aspirin, non-steroidal anti-inflammatory drugs, or other anti-platelet drugs one week before the procedure.
Patients with abnormal hepatic vascular (especially arterial supply) or biliary (especially re-implantation of bile duct) anatomy or gastric acid hypersecretion syndromes may be at increased risk of peri-procedural complications or other severe adverse reactions. Screen patients for a history of prior surgeries involving the bile duct to assess whether the patient is an appropriate candidate for HEPZATO KIT and monitor patients for adverse reactions following HEPZATO KIT administration. Procedure-related reductions in blood pressure including severe hypotension can occur during the HEPZATO KIT procedure.
Closely monitor blood pressure during the procedure. Patients may require fluid support and vasopressors. To reduce the risk of severe hypotension, assess hypothalamic-pituitary-adrenal axis function, and temporarily discontinue ACE-inhibitors, calcium channel blockers, or alpha-1-adrenergic blockers for at least 5 half-lives prior to treatment with the HEPZATO-KIT.
If necessary, use other short-acting antihypertensive drugs to manage blood pressure during the peri-procedure period.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug-device combination cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse drug reactions (ADRs) described in this section were identified from the FOCUS trial. FOCUS was a multicenter trial that evaluated HEPZATO (melphalan) administered via the HEPZATO KIT in patients with unresectable hepatic metastases from uveal melanoma.
In the FOCUS trial, a total of 95 patients were enrolled into the HEPZATO KIT arm, of which 91 patients received treatment with HEPZATO. Serious adverse reactions occurred in 45% of patients who received HEPZATO. Serious adverse reactions occurring in ≥ 2% of patients were thrombocytopenia (10%), neutropenia (8%), febrile neutropenia (7%), platelet count decreased (6%), leukopenia (4.2%), cardiac arrest (3.2%), neutrophil count decreased (2.1%), hypoxia (2.1%), pleural effusion (2.1%), pulmonary edema (2.1%), and deep vein thrombosis (2.1%).
Fatal adverse reactions occurred in 3 (3.2%) patients who were treated with HEPZATO; these included cardiac arrest, acute hepatic failure and bacterial peritonitis. HEPZATO was permanently discontinued due to adverse reactions in 18% of patients with neutropenia being the most common adverse reaction (3.2%) requiring permanent discontinuation. Dose reductions due to an adverse reaction occurred in 14% of patients who received HEPZATO.
Adverse reactions which required dose reductions occurring in ≥ 2% of patients were platelet count decreased (6%), neutropenia (4.2%), anemia (2.1%), and thrombocytopenia (2.1%). Adverse reactions that required dosage interruption in ≥ 2% of patients who received HEPZATO were platelet count decreased (6%), neutropenia (5%), thrombocytopenia (3.2%), anemia (3.2%) and febrile neutropenia (2.1%). The most common (≥20%) adverse reactions or laboratory abnormalities reported in patients treated with HEPZATO were thrombocytopenia (65%), fatigue (65%), anemia (63%), nausea (57%), musculoskeletal pain (46%), leukopenia (46%), abdominal pain (39%), neutropenia (35%), vomiting (35%), increased alanine aminotransferase (32%), prolonged activated partial thromboplastin time (28%), increased aspartate aminotransferase (28%), increased blood alkaline phosphatase (27%), and dyspnea (23%).

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS HEPZATO should not be used in patients < 35 kg. ( 2.2 ) Lactation: Advise not to breastfeed ( 8.2 )
8.1Pregnancy Risk Summary Based on animal studies and its mechanism of action, melphalan can cause fetal harm when administered to a pregnant woman, including teratogenicity and/or embryo-fetal lethality [see Clinical Pharmacology ( 12.1 ) ]. Melphalan is a genotoxic drug and can cause chromatid or chromosome damage in humans [see Nonclinical Toxicology ( 13.1 ) ]. In animal studies, melphalan was embryolethal and teratogenic in rats at doses below the recommended clinical doses [see Data ].
Advise a pregnant woman of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the background risk in the United States general population of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies.
Data Animal Data Adequate animal studies have not been conducted with IV melphalan. Melphalan was embryolethal and teratogenic in rats following oral administration of 6 to 18 mg/m 2 /day for ten (10) days (0.05 to 0.16 times the recommended clinical dose of 3 mg/kg or 111 mg/m 2 /day) and intraperitoneal administration of 18 mg/m 2 (0.16 times the highest recommended clinical dose). Malformations resulting from melphalan administration included alterations of the brain (underdevelopment, deformation, meningocele, and encephalocele) and eye (anophthalmia and microphthalmos), reduction of the mandible and tail, and hepatocele (exomphaly).
8.2Lactation Risk Summary It is not known whether melphalan is present in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing children from melphalan, breastfeeding is not recommended during treatment with melphalan and for one week after the last dose.
8.3Females and Males of Reproductive Potential Melphalan can cause fetal harm when administered to a pregnant woman. Verify the pregnancy status of females of reproductive potential prior to initiating HEPZATO [see Use in Specific Populations ( 8.1 )] . Contraception Females Advise females of reproductive potential to use effective contraception during treatment with HEPZATO and for 6 months after the last dose.
Males HEPZATO administration may damage spermatozoa and testicular tissue, resulting in possible genetic fetal abnormalities. Advise males with female partners of reproductive potential to use effective contraception during treatment with HEPZATO and for 3 months after the last dose [see Nonclinical Toxicology ( 13.1 ) ]. Infertility Females Melphalan causes suppression of ovarian function in premenopausal women, resulting in amenorrhea in a significant number of patients.
Males Reversible and irreversible testicular suppression has been reported in male patients after administration of melphalan.
8.4Pediatric Use The safety and effectiveness in pediatric patients have not been established.
8.5Geriatric Use Clinical studies of HEPZATO did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In the FOCUS trial, 30 of the 91 patients (33%) were 65 years and older.
🤰 Pregnancy ▾
8.1Pregnancy Risk Summary Based on animal studies and its mechanism of action, melphalan can cause fetal harm when administered to a pregnant woman, including teratogenicity and/or embryo-fetal lethality [see Clinical Pharmacology ( 12.1 ) ]. Melphalan is a genotoxic drug and can cause chromatid or chromosome damage in humans [see Nonclinical Toxicology ( 13.1 ) ]. In animal studies, melphalan was embryolethal and teratogenic in rats at doses below the recommended clinical doses [see Data ].
Advise a pregnant woman of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the background risk in the United States general population of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies.
Data Animal Data Adequate animal studies have not been conducted with IV melphalan. Melphalan was embryolethal and teratogenic in rats following oral administration of 6 to 18 mg/m 2 /day for ten (10) days (0.05 to 0.16 times the recommended clinical dose of 3 mg/kg or 111 mg/m 2 /day) and intraperitoneal administration of 18 mg/m 2 (0.16 times the highest recommended clinical dose). Malformations resulting from melphalan administration included alterations of the brain (underdevelopment, deformation, meningocele, and encephalocele) and eye (anophthalmia and microphthalmos), reduction of the mandible and tail, and hepatocele (exomphaly).

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Melphalan is an alkylating drug 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. It is active against both resting and rapidly dividing tumor cells.
12.2Pharmacodynamics Exposure-Response Melphalan exposure-response relationships and the time course of pharmacodynamic response following administration of HEPZATO via the Hepatic Delivery System are not fully characterized.
12.3Pharmacokinetics Geometric mean of systemic melphalan maximum concentration (C max ) is 2.4 (%CV 3.0) mcg/mL and the AUC 0-last was 1.8 (%CV 1.1) mcg*hr/mL. The melphalan median (range) time to C max (T max ) is 0.57 (0.05 – 1.18) hours following administration of HEPZATO. Distribution The melphalan plasma protein binding is approximately 78% following administration of HEPZATO.
Serum albumin accounts for approximately 40% to 60% and α 1 -acid glycoprotein approximately 20% of the plasma protein binding. Elimination The median terminal elimination phase half-life of 1.07 hours that is consistent with IV melphalan administration. Metabolism: Melphalan is primarily metabolized by hydrolysis to inactive metabolites.
Excretion: Liver uptake and removal of melphalan by isolation of hepatic venous blood and subsequent filtration by HDS are the two main processes for reducing the amount of melphalan that is available systemically following administration of HEPZATO. HDS reduced systemic melphalan exposure with a mean (SD) filter efficiency of 82.7% (14.4%) for the total filtration period. Systemic melphalan is eliminated by renal excretion of parent drug and metabolites.
Specific Populations No clinically significant differences in the pharmacokinetics of melphalan were observed based on body weight (43 - 150 kg), creatinine clearance (> 50 mL/min), or hepatic parameters (ALT (7 - 157 IU/L), AST (11 - 90 IU/L), or bilirubin (0.06 - 1.5 mg/dL) following administration of HEPZATO KIT.
