AbbVie (NYSE: ABBV) today announced that the U.S. Food and Drug Administration (FDA) has granted full approval for ELAHERE® (mirvetuximab soravtansine-gynx) for the treatment of folate receptor alpha (FRα)-positive, platinum-resistant epithelial ovarian, fallopian tube or primary peritoneal adult cancer patients treated with up to three prior therapies.
| - The full approval of ELAHERE is based on the confirmatory MIRASOL Phase 3 trial that supports the medicine as a potential new standard of care for folate receptor alpha (FRα)-positive, platinum-resistant ovarian cancer (PROC) NORTH CHICAGO, Ill., March 22, 2024 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that the U.S. Food and Drug Administration (FDA) has granted full approval for ELAHERE® (mirvetuximab soravtansine-gynx) for the treatment of folate receptor alpha (FRα)-positive, platinum-resistant epithelial ovarian, fallopian tube or primary peritoneal adult cancer patients treated with up to three prior therapies. Patients with these cancers often present with late-stage disease, undergo surgery and are then treated with platinum-based chemotherapy. They may become resistant to this treatment and require another therapy, such as ELAHERE. “The full FDA approval of ELAHERE for eligible patients with ovarian cancer represents the culmination of years of work by the ImmunoGen team. ELAHERE is the first and only antibody-drug conjugate (ADC) approved in the U.S. for this difficult-to-treat malignancy,” said Roopal Thakkar, M.D., senior vice president, chief medical officer, global therapeutics, AbbVie. ELAHERE was first granted FDA accelerated approval in November 2022 and the conversion to full approval is based on data from the confirmatory Phase 3 MIRASOL trial. This trial compared ELAHERE to investigator’s choice (IC) of chemotherapy in patients with platinum-resistant ovarian cancer (PROC) whose tumors express high levels of FRα and who have been treated with up to three prior therapies. The primary endpoint of MIRASOL was progression-free survival (PFS) by investigator assessment and key secondary endpoints included objective response rate (ORR) and overall survival (OS). “As the first treatment to show a statistically significant overall survival benefit in patients with platinum-resistant ovarian cancer, ELAHERE provides an effective new option for patients with folate receptor alpha positive tumors. These patients previously had very limited options and ELAHERE changes that,” said Kathleen Moore, deputy director and associate director of clinical research at the Stephenson Cancer Center of The University of Oklahoma and MIRASOL principal investigator. ABOUT THE PHASE 3 MIRASOL TRIAL Based on current results:
The most common (≥20%) adverse reactions, including lab abnormalities, were increased aspartate aminotransferase, fatigue, increased alanine aminotransferase, blurred vision, nausea, increased alkaline phosphatase, diarrhea, abdominal pain, keratopathy, peripheral neuropathy, musculoskeletal pain, decreased lymphocytes, decreased platelets, decreased magnesium, decreased hemoglobin, dry eye, constipation, decreased leukocytes, vomiting, decreased albumin, decreased appetite, and decreased neutrophils. ABOUT OVARIAN CANCER ABOUT ELAHERE The Marketing Authorization Application (MAA) for ELAHERE in Europe has been accepted by the European Medicines Agency (EMA). Regulatory submissions for ELAHERE are also under review in multiple other countries. INDICATION IMPORTANT SAFETY INFORMATION WARNING: OCULAR TOXICITY
WARNINGS and PRECAUTIONS 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 59% of patients with ovarian cancer treated with ELAHERE. Eleven percent (11%) of patients experienced Grade 3 ocular adverse reactions, including blurred vision, keratopathy (corneal disorders), dry eye, cataract, photophobia, and eye pain; two patients (0.3%) experienced Grade 4 events (keratopathy and cataract). The most common (≥5%) ocular adverse reactions were blurred vision (48%), keratopathy (36%), dry eye (27%), cataract (16%), photophobia (14%), and eye pain (10%). The median time to onset for first ocular adverse reaction was 5.1 weeks (range: 0.1 to 68.6). Of the patients who experienced ocular events, 53% had complete resolution; 38% 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 1% of patients. Premedication and use of lubricating and ophthalmic topical steroid eye drops during treatment with ELAHERE are recommended. 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. Pneumonitis 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 1% with Grade 3 events and 1 patient (0.1%) with a Grade 4 event. One patient (0.1%) died due to respiratory failure in the setting of pneumonitis and lung metastases. One patient (0.1%) died due to respiratory failure of unknown etiology. Pneumonitis led to permanent discontinuation of ELAHERE 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. Patients who are asymptomatic may continue dosing of ELAHERE with close monitoring. Peripheral Neuropathy (PN) Peripheral neuropathy occurred in 36% of patients with ovarian cancer treated with ELAHERE across clinical trials; 3% of patients experienced Grade 3 peripheral neuropathy. Peripheral neuropathy adverse reactions included peripheral neuropathy (20%), peripheral sensory neuropathy (9%), paraesthesia (6%), neurotoxicity (3%), hypoaesthesia (1%), peripheral motor neuropathy (0.9%), polyneuropathy (0.3%), and peripheral sensorimotor neuropathy (0.1%). 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 PN, withhold dosage, dose reduce, or permanently discontinue ELAHERE based on the severity of PN. Embryo-Fetal Toxicity 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. ADVERSE REACTIONS The most common (≥20 %) adverse reactions, including lab abnormalities, were increased aspartate aminotransferase, fatigue, increased alanine aminotransferase, blurred vision, nausea, increased alkaline phosphatase, diarrhea, abdominal pain, keratopathy, peripheral neuropathy, musculoskeletal pain, decreased lymphocytes, decreased platelets, decreased magnesium, decreased hemoglobin, dry eye, constipation, decreased leukocytes, vomiting, decreased albumin, decreased appetite, and decreased neutrophils. DRUG INTERACTIONS DM4 is a CYP3A4 substrate. Closely monitor patients for adverse reactions with ELAHERE when used concomitantly with strong CYP3A4 inhibitors.
