About This Medication

11 DESCRIPTION Evomela contains melphalan hydrochloride, an alkylating drug, as the active ingredient. The chemical name of melphalan hydrochloride is 4-[bis(2-chloroethyl)amino]-L-phenylalanine hydrochloride. Its molecular formula is C 13 H 18 Cl 2 N 2 O 2 • HCl and the molecular weight is 341.67. The structural formula is: Melphalan hydrochloride is a white to off-white powder, with a melting range of 199°C − 201°C. It is practically insoluble in water, but freely soluble in 1N HCl and methanol. Evomela (melphalan) for injection is supplied as a sterile white to off-white lyophilized powder in a single-dose vial for intravenous use. Each vial contains 50 mg melphalan free base equivalent to 56 mg melphalan hydrochloride and 2700 mg Betadex Sulfobutyl Ether Sodium, NF. Sodium hydroxide and if necessary, hydrochloric acid are added as a pH adjuster. melphalan structure

Chỉ định & Cách dùng

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 ) 1.1 Multiple 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.

Cơ chế hoạt động

12.1 Mechanism 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.

Liều dùng & Cách dùng

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 ) 2.1 Recommended 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 )] . 2.2 Preparation 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.

Side Effects Overview

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 )] 6.1 Clinical 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%).

12.3 Pharmacokinetics 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.
