⏳ Availability & generic status
The FDA lists approved generic versions of this medicine, but that does not always mean a pharmacy can get one today. Patent rules, launch agreements, supply and pricing can affect when generics actually arrive.
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.

1 INDICATIONS AND USAGE Evomela is an alkylating drug indicated for use as a high-dose conditioning treatment prior to hematopoietic progenitor (stem) cell transplantation in patients with multiple myeloma. ( 1.1 )
1.1Multiple Myeloma-Conditioning Treatment Evomela is indicated for use as a high-dose conditioning treatment prior to hematopoietic progenitor (stem) cell transplantation in patients with multiple myeloma.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION For Conditioning Treatment , the recommended dose of Evomela is 100 mg/m 2 /day administered over 30 minutes by intravenous infusion for 2 consecutive days (Day -3 and Day -2) prior to autologous stem cell transplantation (ASCT, Day 0). ( 2.1 )
2.1Recommended Dosage for Conditioning Treatment The recommended dose of Evomela for conditioning treatment is 100 mg/m 2 /day administered over 30 minutes by intravenous infusion for 2 consecutive days (Day -3 and Day -2) prior to autologous stem cell transplantation (ASCT, Day 0). For patients who weigh more than 130% of their ideal body weight, body surface area should be calculated based on adjusted ideal body weight. Administer prophylactic antiemetics [see Warnings and Precautions ( 5.2 )] .
2.2Preparation and Administration Evomela is a hazardous drug. Follow applicable special handling and disposal procedures 1 . Evomela is light sensitive.
Retain in original carton until use. Do not mix Evomela with other melphalan hydrochloride for injection drug products. Reconstitution and Infusion Instructions: 1.
Use 0.9% Sodium Chloride Injection, USP (8.6 mL as directed) to reconstitute Evomela and make a 50 mg/10 mL (5 mg/ mL) nominal concentration of melphalan. The reconstituted Evomela drug product is stable for 24 hours at refrigerated temperature (5 o C) without any precipitation due to the high solubility. The reconstituted Evomela drug product is stable for 1 hour at room temperature.
2. Calculate the required volume of Evomela needed for a patient’s dose and withdraw that volume from the vial(s). 3.
Add the required volume of Evomela to the appropriate volume of 0.9% Sodium Chloride Injection, USP to a final concentration of 0.45 mg/mL. The Evomela admixture solution is stable for 4 hours at room temperature in addition to the 1 hour following reconstitution. 4.
Infuse over 30 minutes via an injection port or central venous catheter. Evomela may cause local tissue damage should extravasation occur. Do not administer by direct injection into a peripheral vein.
Administer Evomela by injecting slowly into a fast-running IV infusion via a central venous access line. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
💊 Dosage Forms and Strengths ▾
3 DOSAGE FORMS AND STRENGTHS For injection: 50 mg, white to off-white lyophilized powder in single-dose vial for reconstitution (after reconstitution the solution is clear and colorless to light yellow). Each vial contains 50 mg melphalan free base equivalent to 56 mg melphalan hydrochloride. For Injection: 50 mg per vial, lyophilized powder in a single-dose vial for reconstitution. ( 3 )
⛔ Contraindications ▾
4 CONTRAINDICATIONS History of serious allergic reaction to melphalan. History of serious allergic reaction to melphalan
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Gastrointestinal toxicity: Nausea, vomiting, diarrhea or oral mucositis may occur; provide supportive care using antiemetic and antidiarrheal medications as needed. ( 2.1 , 5.2 ) 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.
( 5.6 , 8.1 , 8.3 ) Infertility: Melphalan may cause ovarian function suppression or testicular suppression. ( 5.7 )
5.1Bone Marrow Suppression For patients receiving Evomela as part of a conditioning regimen, myeloablation occurs in all patients. Do not begin the conditioning regimen if a stem cell product is not available for rescue. Monitor complete blood counts, provide supportive care for infections, anemia and thrombocytopenia until there is adequate hematopoietic recovery.
5.2Gastrointestinal Toxicity For patients receiving Evomela as part of a conditioning regimen, nausea, vomiting, mucositis, and diarrhea may occur in over 50% of patients. Use prophylactic antiemetic medication. Provide supportive care for nausea, vomiting, diarrhea, and mucositis.
The frequency of grade 3/4 mucositis in clinical studies was 13%. Provide nutritional support and analgesics for patients with severe mucositis. [see Dosage and Administration ( 2.1 ) and Adverse Reactions ( 6.1 )] .
5.3Hepatotoxicity Hepatic disorders ranging from abnormal liver function tests to clinical manifestations such as hepatitis and jaundice have been reported after treatment with melphalan. Hepatic veno-occlusive disease has also been reported. Monitor liver chemistries.
5.4Hypersensitivity Acute hypersensitivity reactions, including anaphylaxis, have occurred in approximately 2% of patients who received an intravenous formulation of melphalan. Symptoms may include urticaria, pruritus, edema, and skin rashes and, in some patients, tachycardia, bronchospasm, dyspnea, and hypotension. Discontinue treatment with Evomela for serious hypersensitivity reactions.
5.5Secondary Malignancies Melphalan has been shown to cause chromatid or chromosome damage in humans. Secondary malignancies such as myeloproliferative syndrome or acute leukemia have been reported in multiple myeloma patients treated with melphalan-containing chemotherapy regimens. The potential benefit of Evomela therapy must be considered against the possible risk of the induction of a secondary malignancy.
5.6Embryo-Fetal Toxicity Based on its mechanism of action, Evomela can cause fetal harm when administered to a pregnant woman. Melphalan is genotoxic, targets actively dividing cells, and was embryolethal and teratogenic in rats. Advise pregnant women of the potential risk to a fetus.
Advise females of reproductive potential to use effective contraception during treatment with Evomela and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with Evomela and for 3 months after the last dose [see Use in Specific Populations ( 8.1 , 8.3 )] .
5.7Infertility Melphalan-based chemotherapy regimens have been reported to cause suppression of ovarian function in premenopausal women, resulting in persistent amenorrhea in approximately 9% of patients. Reversible or irreversible testicular suppression has also been reported [see Use in Specific Populations ( 8.3 )].
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Most common adverse reactions observed in at least 50% of patients treated with Evomela are neutrophil count decreased, white blood cell count decreased, lymphocyte count decreased, platelet count decreased, diarrhea, nausea, fatigue, hypokalemia, anemia, and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Acrotech Biopharma Inc. at 1-888-292-9617 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch The following serious adverse reactions are described in more detail in other sections of the prescribing information. • Bone Marrow Suppression [see Warnings and Precautions ( 5.1 )] • Gastrointestinal Toxicity [see Warnings and Precautions ( 5.2 )] • Hepatotoxicity [see Warnings and Precautions ( 5.3 )] • Hypersensitivity [see Warnings and Precautions ( 5.4 )] • Secondary Malignancies [see Warnings and Precautions ( 5.5 )]
6.1Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of Evomela may not reflect the rates observed in practice. The most common adverse reactions observed in at least 50% of patients with multiple myeloma treated with Evomela were neutrophil count decreased, white blood cell count decreased, lymphocyte count decreased, platelet count decreased, diarrhea, nausea, fatigue, hypokalemia, anemia, and vomiting. Myeloablative Conditioning in Multiple Myeloma Patients Undergoing ASCT The safety of Evomela was evaluated in 61 patients with multiple myeloma in a single arm clinical trial in which patients were administered Evomela at a dosage of 100 mg/m 2 /day administered over ~30 minutes (range: 24-48 minutes) by intravenous (IV) infusion for 2 consecutive days (Day -3 and Day -2) prior to autologous stem cell transplant (ASCT, Day 0). [see Clinical Studies ( 14.1 )].
Table 1 summarizes the adverse reactions from the single-arm trial in patients with multiple myeloma. Severe myelosuppression is expected and these adverse reactions are not listed below.

The most common serious adverse reactions (>1 patient, 1.6%) were pyrexia, hematochezia, febrile neutropenia, and renal failure. Treatment-related serious adverse reactions reported in >1 patient were pyrexia (n=2, 3%), febrile neutropenia (n=2, 3%), and hematochezia (n=2, 3%).
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS No formal drug interaction studies have been conducted. The development of severe renal impairment has been reported in patients treated with a single dose of intravenous melphalan 140-250 mg/m 2 followed by standard oral doses of cyclosporine. Intravenous melphalan may also reduce the threshold for BCNU lung toxicity.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Advise not to breastfeed ( 8.2 )
8.1Pregnancy Risk Summary Based on its mechanism of action, Evomela 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 U.S. general population of major birth defects is 2-4% and of miscarriage is 15-20% of clinically recognized pregnancies.
Data Animal Data Adequate animal studies have not been conducted with intravenous melphalan. Melphalan was embryolethal and teratogenic in rats following oral administration of 6 to 18 mg/m 2 /day for 10 days (0.06 to 0.18 times the highest recommended clinical dose of 100 mg/m 2 /day) and intraperitoneal administration of 18 mg/m 2 (0.18 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 Evomela and for one week after the last dose.
8.3Females and Males of Reproductive Potential Evomela can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )] . Contraception Females Advise females of reproductive potential to use effective contraception during treatment with Evomela and for 6 months after the last dose. Males Evomela 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 Evomela 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 Pediatric patients were not included in clinical trials. Safety and effectiveness have not been established in pediatric patients.
8.5Geriatric Use Of the total number of subjects in the single-arm pivotal study of Evomela, 30% were 65 and over, but no patients were 75 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects. A greater incidence of engraftment syndrome was observed in older patients; 7% (3 of 43) of patients younger than 65 years old versus 28% (5 of 18) of patients 65 years old and over.
🤰 Pregnancy ▾
8.1Pregnancy Risk Summary Based on its mechanism of action, Evomela 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 U.S. general population of major birth defects is 2-4% and of miscarriage is 15-20% of clinically recognized pregnancies.
Data Animal Data Adequate animal studies have not been conducted with intravenous melphalan. Melphalan was embryolethal and teratogenic in rats following oral administration of 6 to 18 mg/m 2 /day for 10 days (0.06 to 0.18 times the highest recommended clinical dose of 100 mg/m 2 /day) and intraperitoneal administration of 18 mg/m 2 (0.18 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).
🧒 Pediatric Use ▾
8.4Pediatric Use Pediatric patients were not included in clinical trials. Safety and effectiveness have not been established in pediatric patients.
🆘 Overdosage ▾
10 OVERDOSAGE Overdoses resulting in death have been reported with melphalan. Overdoses, including doses up to 290 mg/m 2 , 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/m 2 ).
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 leading to leucopenia, thrombocytopenia and anemia. 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/m 2 overdose treated with standard supportive care.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action 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 N 7 position of guanine. Like other bifunctional alkylating agents, it is active against both resting and rapidly dividing tumor cells.
12.2Pharmacodynamics The peak mean heart rate increased 20 bpm from baseline following melphalan 100 mg/m 2 for 2 consecutive days in multiple myeloma patients undergoing autologous stem cell transplantation. Cardiac Electrophysiology No large mean increase in QTc (i.e. > 20 ms) was detected following melphalan 100 mg/m 2 .
12.3Pharmacokinetics Mean (± SD) peak plasma concentrations and AUC 0-inf were 5.8 ± 1.5 mcg/mL and 451 ± 109 mcg*min/mL, respectively, following administration of melphalan 100 mg/m 2 in multiple myeloma patients. Distribution The volume of distribution of melphalan ranges from approximately 35.5 to 185.7 L/m 2 . Melphalan penetrates into cerebrospinal fluid (CSF).
Protein binding of melphalan ranges from approximately 50% to 90%, primarily to serum albumin (40% to 60%) and to a lesser extent to α1-acid glycoprotein (20%). Approximately 30% of melphalan is (covalently) irreversibly bound to plasma proteins. Elimination Melphalan terminal elimination half-life is approximately 75 minutes.
Average total body clearance (CL) ranges from approximately 250 to 325 mL/min/m 2 . Metabolism Melphalan primarily undergoes chemical hydrolysis to inactive metabolites. Excretion Mean values of melphalan excreted in urine range from 5.8% to 21.3%.
Specific Populations Patient Body Weight Melphalan clearance changes with ideal body weight (IBW), which decreased by 28% and increased by 31% with IBW of 45 kg and 100 kg compared to 70 kg IBW, respectively. Renal Impairment A decrease in estimated creatinine CL from 100 mL/min to 30 mL/min results in 28.2% reduction in CL for a typical person with an IBW of 70 kg.
