- ELAHERE can cause severe ocular toxicities, including visual impairment, keratopathy, dry eye, photophobia, eye pain, and uveitis [see WARNINGS AND PRECAUTIONS and ADVERSE REACTIONS].
- Conduct an ophthalmic exam including visual acuity and slit lamp exam prior to initiation of ELAHERE, every other cycle for the first 8 cycles, and as clinically indicated [see DOSAGE AND ADMINISTRATION].
- Administer prophylactic artificial tears and ophthalmic topical steroids [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
- Withhold ELAHERE for ocular toxicities until improvement and resume at the same or reduced dose [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
- Discontinue ELAHERE for Grade 4 ocular toxicities [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
Mirvetuximab soravtansine-gynx is a folate receptor alpha (FRα)-directed antibody-drug conjugate (ADC) consisting of three components: 1) an anti-FRα monoclonal antibody of IgG1 subtype 2) the small molecule anti-tubulin agent DM4 (a maytansine derivative) and 3) a linker, sulfo-SPDB (1-(2,5-dioxopyrrolidin-1-yl)oxy-1-oxo-4-(pyridin-2-yldisulfanyl)butane-2-sulfonic acid) that covalently attaches DM4 to the mirvetuximab antibody. Mirvetuximab soravtansine-gynx has an approximate molecular weight of 150 kDa. An average of 3.4 molecules of DM4 are attached to each antibody molecule. Mirvetuximab soravtansine-gynx is produced by chemical conjugation of the antibody and small molecule components. The antibody is produced by mammalian (Chinese hamster ovary) cells, and the small molecule components are produced by chemical synthesis.
Mirvetuximab soravtansine-gynx has the following structure:
ELAHERE (mirvetuximab soravtansine-gynx) injection is supplied as a sterile, preservative-free, clear to slightly opalescent, colorless solution containing 100 mg/20 mL of mirvetuximab soravtansine-gynx in single-dose vials. Each mL of solution contains 5 mg of mirvetuximab soravtansine-gynx, and glacial acetic acid (0.22 mg), polysorbate 20 (0.1 mg), sodium acetate (0.53 mg), sucrose (90 mg), and Water for Injection. The pH is approximately 5.0.
The ELAHERE vial stoppers are not made with natural rubber latex.
ELAHERE™ is indicated for the treatment of adult patients with folate receptor-alpha (FRα) positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received one to three prior systemic treatment regimens. Select patients for therapy based on an FDA-approved test [see DOSAGE AND ADMINISTRATION].
This indication is approved under accelerated approval based on tumor response rate and durability of response [see Clinical Studies ]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
DOSAGE AND ADMINISTRATION
Select patients for the treatment of platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer with ELAHERE based on the presence of FRα tumor expression [see INDICATIONS & USAGE and Clinical Studies] using an FDA-approved test.
Information on FDA-approved tests for the measurement of FRα tumor expression is available at http://www.fda.gov/CompanionDiagnostics.
The recommended dose of ELAHERE is 6 mg/kg adjusted ideal body weight (AIBW) administered once every 3 weeks (21-day cycle) as an intravenous infusion until disease progression or unacceptable toxicity [see DOSAGE AND ADMINISTRATION].
The total dose of ELAHERE is calculated based on each patientâ€™s AIBW using the following formula:
AIBW = Ideal Body Weight (IBW [kg]) + 0.4*(Actual weight [kg] â€“ IBW)
Female IBW (kg) = 0.9*height(cm) â€“ 92
Premedication And Required Eye Care
Administer the premedications in Table 1 prior to each infusion of ELAHERE to reduce the incidence and severity of infusion related reactions (IRRs), nausea, and vomiting.
Table 1: Premedication Prior to Each ELAHERE Infusion
|Premedication||Route of Administration||Examples (or equivalent)||Administration Time Prior to ELAHERE Infusion|
|Corticosteroid||intravenous||dexamethasone 10 mg||At least 30 minutes prior|
|Antihistamine||oral or intravenous||diphenhydramine 25 mg to 50 mg|
|Antipyretic||oral or intravenous||acetaminophen 325 mg to 650 mg|
|Antiemetic||oral or intravenous||5-HT3 serotonin receptor antagonist or appropriate alternatives||Before each dose and thereafter as needed|
Consider additional premedications including corticosteroids the day prior to ELAHERE administration for patients who experienced IRRs.
Ophthalmic Exams And Premedication
Ophthalmic Topical Steroids
The use of ophthalmic topical steroids is recommended. The initial prescription and renewals of any corticosteroid medication should be made only after examination with a slit lamp. Administer one drop of ophthalmic topical steroids in each eye 6 times daily starting the day prior to each infusion until day 4; then administer one drop in each eye 4 times daily for days 5-8 of each cycle of ELAHERE [see WARNINGS AND PRECAUTIONS].
Lubricating Eye Drops
The use of lubricating eye drops at least four times daily and as needed is recommended during treatment with ELAHERE. Instruct patients to use lubricating eye drops and advise to wait at least 10 minutes after ophthalmic topical steroid administration before instilling lubricating eye drops [see WARNINGS AND PRECAUTIONS].

Instructions For Preparation And Administration
- ELAHERE is a hazardous drug. Follow applicable special handling and disposal procedures1.
- Calculate the dose (mg) (based on the patientâ€™s AIBW), total volume (mL) of solution required, and the number of vials of ELAHERE needed [see Recommended Dosage and Dose Modifications]. More than one vial will be needed for a full dose.
- Remove the vials of ELAHERE from the refrigerator and allow to warm to room temperature.
- Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. ELAHERE is a clear to slightly opalescent, colorless solution.
- Gently swirl and inspect each vial prior to withdrawing the calculated dose volume of ELAHERE for subsequent further dilution. Do not shake the vial.
- Using aseptic technique, withdraw the calculated dose volume of ELAHERE for subsequent further dilution.
- ELAHERE contains no preservatives and is intended for single-dose only. Discard any unused drug remaining in the vial.
- ELAHERE must be diluted prior to administration with 5% Dextrose Injection, USP to a final concentration of 1 mg/mL to 2 mg/mL.
- ELAHERE is incompatible with 0.9% Sodium Chloride Injection. ELAHERE must not be mixed with any other drugs or intravenous fluids.
- Determine the volume of 5% Dextrose Injection, USP required to achieve the final diluted drug concentration. Either remove excess 5% Dextrose Injection, USP from a prefilled intravenous bag or add the calculated volume of 5% Dextrose Injection, USP to a sterile empty intravenous bag. Then add the calculated dose volume of ELAHERE to the intravenous bag.
- Gently mix the diluted drug solution by slowly inverting the bag several times to assure uniform mixing. Do not shake or agitate.
- If the diluted infusion solution is not used immediately, store solution either at ambient temperature [(18°C to 25°C (64.4°F to 77°F)] for no more than 8 hours (including infusion time), or under refrigeration at 2°C to 8°C (36°F to 46°F) for no more than 12 hours. If refrigerated, allow the infusion bag to reach room temperature prior to administration. After refrigeration, administer diluted infusion solutions within 8 hours (including infusion time).
- Do not freeze prepared infusion solution.
- Inspect the ELAHERE intravenous infusion bag visually for particulate matter and discolorationprior to administration.
- Administer pre-medications prior to ELAHERE administration [see Premedication and Prophylactic Regimen].
- Administer ELAHERE as an intravenous infusion only, using a 0.2 or 0.22 μm polyethersulfone(PES) in-line filter. Do not substitute other membrane materials.
- Administer the initial dose as an intravenous infusion at the rate of 1 mg/min. If well tolerated after30 minutes at 1 mg/min, the infusion rate can be increased to 3 mg/min. If well tolerated after 30minutes at 3 mg/min, the infusion rate can be increased to 5 mg/min.
- If no infusion-related reactions occur with the previous dose, subsequent infusions should be startedat the maximally tolerated rate and may be increased up to a maximum infusion rate of 5 mg/min, astolerated.
- Following the infusion, flush the intravenous line with 5% Dextrose Injection, USP to ensuredelivery of the full dose. Do not use any other intravenous fluids for flushing.

Effects Of Other Drugs On ELAHERE
Strong CYP3A4 Inhibitors
DM4 is a CYP3A4 substrate. Concomitant use of ELAHERE with strong CYP3A4 inhibitors may increase unconjugated DM4 exposure [see CLINICAL PHARMACOLOGY], which may increase the risk of ELAHERE adverse reactions [see ADVERSE REACTIONS]. Closely monitor patients for adverse reactions with ELAHERE when used concomitantly with strong CYP3A4 inhibitors [see WARNINGS AND PRECAUTIONS].
Included as part of the PRECAUTIONS section.
ELAHERE can cause severe ocular adverse reactions, including visual impairment, keratopathy (corneal disorders), dry eye, photophobia, eye pain, and uveitis. Ocular adverse reactions occurred in 61% of patients with ovarian cancer treated with ELAHERE. Nine percent (9%) of patients experienced Grade 3 ocular adverse reactions, including visual impairment, keratopathy/keratitis (corneal disorders), dry eye, photophobia, and eye pain; and one patient (0.2%) experienced Grade 4 keratopathy. The most common (≥5%) ocular adverse reactions were visual impairment (49%), keratopathy (36%), dry eye (26%), cataract (15%), photophobia (13%), and eye pain (12%) [see ADVERSE REACTIONS].
The median time to onset for first ocular adverse reaction was 1.2 months (range: 0.03 to 12.9). Of the patients who experienced ocular events, 49% had complete resolution and 39% had partial improvement (defined as a decrease in severity by one or more grades from the worst grade) at last follow up. Ocular adverse reactions led to permanent discontinuation of ELAHERE in 0.6% of patients.
Premedication and use of lubricating and ophthalmic topical steroid eye drops during treatment with ELAHERE are recommended [see DOSAGE AND ADMINISTRATION]. Advise patients to avoid use of contact lenses during treatment with ELAHERE unless directed by a healthcare provider.
Refer patients to an eye care professional for an ophthalmic exam including visual acuity and slit lamp exam prior to treatment initiation, every other cycle for the first 8 cycles, and as clinically indicated. Promptly refer patients to an eye care professional for any new or worsening ocular signs and symptoms.
Monitor for ocular toxicity and withhold, reduce, or permanently discontinue ELAHERE based on severity and persistence of ocular adverse reactions. [see DOSAGE AND ADMINISTRATION].
Severe, life-threatening, or fatal interstitial lung disease (ILD), including pneumonitis, can occur in patients treated with ELAHERE.
Pneumonitis occurred in 10% of patients treated with ELAHERE, including 0.8% with Grade 3 events, and 1 patient (0.2%) with a Grade 4 event. One patient (0.2%) died due to respiratory failure in the setting of pneumonitis and lung metastases. Pneumonitis resulted in ELAHERE dose reduction in 1%, dose interruptions in 3%, and permanent discontinuation in 3% of patients.
Monitor patients for pulmonary signs and symptoms of pneumonitis, which may include hypoxia, cough, dyspnea, or interstitial infiltrates on radiologic exams. Infectious, neoplastic, and other causes for such symptoms should be excluded through appropriate investigations. Withhold ELAHERE for patients who develop persistent or recurrent Grade 2 pneumonitis until symptoms resolve to ≤ Grade 1 and consider dose reduction. Permanently discontinue ELAHERE in all patients with Grade 3 or 4 pneumonitis [see DOSAGE AND ADMINISTRATION]. Patients who are asymptomatic may continue dosing of ELAHERE with close monitoring.
Peripheral neuropathy occurred in 36% of patients with ovarian cancer treated with ELAHERE across clinical trials; 2% of patients experienced Grade 3 peripheral neuropathy. Peripheral neuropathy adverse reactions included peripheral neuropathy (19%), peripheral sensory neuropathy (9%), paraesthesia (6%), neurotoxicity (3%), hypoaesthesia (2%), peripheral motor neuropathy (1%), neuralgia (0.4%), polyneuropathy (0.2%) and oral hypoesthesia (0.2%).
The median time to onset of peripheral neuropathy was 1.3 months (range 0.03 to 29.1). Of the patients who experienced peripheral neuropathy, 28% had complete resolution and 13% had partial improvement (defined as a decrease in severity by one or more grades from the worst grade) at last follow up. Peripheral neuropathy led to discontinuation of ELAHERE in 0.4% of patients.
Monitor patients for signs and symptoms of neuropathy, such as paresthesia, tingling or a burning sensation, neuropathic pain, muscle weakness, or dysesthesia. For patients experiencing new or worsening peripheral neuropathy, withhold dosage, dose reduce, or permanently discontinue ELAHERE based on the severity of peripheral neuropathy [see DOSAGE AND ADMINISTRATION].
Based on its mechanism of action, ELAHERE can cause embryo-fetal harm when administered to a pregnant woman because it contains a genotoxic compound (DM4) and affects actively dividing cells.
Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with ELAHERE and for 7 months after the last dose [see Use In Specific Populations].
Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Inform patients about the need for eye exams before and during treatment with ELAHERE.
Advise patients to contact their healthcare provider promptly if they experience any visual changes. Advise patients to use steroid eye drops and artificial tear substitutes [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
Advise patients to immediately report new or worsening respiratory symptoms [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS].
Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise female patients to inform their healthcare provider of a known or suspected pregnancy [see Use In Specific Populations].
Advise females of reproductive potential to use effective contraception during treatment with ELAHERE and for 7 months after the last dose [see Use In Specific Populations].
Advise women not to breastfeed during treatment with ELAHERE and for 1 month after the last dose [see Use In Specific Populations].
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Carcinogenicity studies have not been conducted with mirvetuximab soravtansine-gynx or DM4.
DM4 and the metabolite, S-methyl DM4, were clastogenic in the in vivo rat bone marrow micronucleus study. DM4 and S-methyl DM4 were not mutagenic in the bacterial reverse mutation (Ames) assay.
Fertility studies have not been conducted with mirvetuximab soravtansine-gynx or DM4.
Use In Specific Populations
Based on its mechanism of action, ELAHERE can cause embryo-fetal harm when administered to a pregnant woman because it contains a genotoxic compound (DM4) and affects actively dividing cells [see CLINICAL PHARMACOLOGY, Nonclinical Toxicology]. Human immunoglobulin G (IgG) is known to cross the placental barrier; therefore, ELAHERE has the potential to be transmitted from the mother to the developing fetus. There are no available human data on ELAHERE use in pregnant women to inform a drug-associated risk. No reproductive or developmental animal toxicity studies were conducted with mirvetuximab soravtansine-gynx. Advise patients of the potential risk to a fetus.
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
No reproductive or developmental animal toxicity studies have been conducted with mirvetuximab soravtansine-gynx. The cytotoxic component of ELAHERE, DM4, disrupts microtubule function, is genotoxic, and can be toxic to actively dividing cells, suggesting it has the potential to cause embryotoxicity and teratogenicity.
There are no data on the presence of mirvetuximab soravtansine-gynx in human milk or the effects on the breastfed child or milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with ELAHERE and for 1 month after the last dose.
Females And Males Of Reproductive Potential
ELAHERE can cause embryo-fetal harm when administered to a pregnant woman [see Use In Specific Populations].
Verify pregnancy status in females of reproductive potential prior to initiating ELAHERE.
Advise females of reproductive potential to use effective contraception during treatment with ELAHERE and for 7 months after the last dose.
Safety and effectiveness of ELAHERE have not been established in pediatric patients.
Of the 106 patients who were treated in Study 0417, 44% of patients were ≥65 years old. Grade ≥3 adverse reactions occurred in 49% of patients ≥65 years and in 51% <65 years. No clinically meaningful differences in efficacy or safety were observed between patients ≥65 years of age compared to younger patients.
Population pharmacokinetic analysis indicates that age does not have a clinically meaningful effect on the pharmacokinetics of ELAHERE [see CLINICAL PHARMACOLOGY].
No dosage adjustment of ELAHERE is recommended for patients with mild to moderate renal impairment (CLcr 30 to 90 mL/min). The effect of severe renal impairment (CLcr 15 to < 30 mL/min) or end-stage renal disease on ELAHERE is unknown [see CLINICAL PHARMACOLOGY].
Avoid use of ELAHERE in patients with moderate or severe hepatic impairment (total bilirubin >1.5 ULN).
No dosage adjustment of ELAHERE is recommended for patients with mild hepatic impairment (total bilirubin ≤ULN and AST >ULN or total bilirubin >1 to 1.5 times ULN and any AST) [see CLINICAL PHARMACOLOGY].
