Indications for: ELAHERE
Folate receptor-alpha (FRα) positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer, in adults who have received 1–3 prior systemic treatment regimens.
Select patients based on the presence of FRα tumor expression. Premedicate with a corticosteroid (IV), antihistamine, antipyretic, and antiemetic, and with ophthalmic topical steroids, lubricating eye drops; see full labeling. Administer as an IV infusion 6mg/kg adjusted ideal body weight (AIBW) once every 3 weeks (21-day cycle), until disease progression or unacceptable toxicity. Infuse initially at a rate of 1mg/min; may increase to 3mg/min if well tolerated after 30mins, then to 5mg/min after next 30mins (max rate). Dose modifications and reductions: see full labeling.
Monitor for ocular toxicity; withhold, reduce, or permanently discontinue based on severity of reactions. Conduct eye exam including visual acuity and slit lamp exam prior to initiation, every other cycle for the first 8 cycles, and as clinically indicated. Advise to avoid contact lenses during treatment. Monitor for pneumonitis; withhold and consider reducing dose if persistent or recurrent Grade 2 pneumonitis develop; permanently discontinue if Grade 3/4 penumonitis occurs. Monitor for neuropathy; if new or worsening peripheral neuropathy occurs, withhold, reduce dose, or permanently discontinue based on severity of reactions. Moderate to severe hepatic impairment: not recommended. Embryo-fetal toxicity. Advise females of reproductive potential to use effective contraception during and for 7 months after the last dose. Pregnancy: exclude status prior to initiation. Nursing mothers: not recommended (during and for 1 month after the last dose).
Folate receptor alpha-directed antibody-drug conjugate.
May be potentiated by strong CYP3A4 inhibitors; monitor.
