Bladder, kidney, and other urologic cancers:
Indications for INLYTA:
Treatment of advanced renal cell carcinoma (RCC) after failure of one prior systemic therapy.
Take 12hrs apart. Swallow whole with a glass of water. Initially 5mg twice daily. If tolerated for at least two consecutive weeks with no adverse reactions >Grade 2, normotensive, and not receiving antihypertensives, may increase dose to 7mg twice daily, then 10mg twice daily. May reduce dose from 5mg twice daily to 3mg twice daily, then 2mg twice daily if additional dose reduction required. Concomitant strong CYP3A4/5 inhibitors: avoid; if warranted, decrease Inlyta dose by approximately ½. If strong CYP3A4/5 inhibitor discontinued, return Inlyta dose (after 3–5 half-lives of the inhibitor) to that used prior to CYP3A4/5 inhibitor initiation. Moderate hepatic impairment: decrease dose by approximately ½.
Control and monitor BP prior to and during therapy; discontinue if severe and persistent hypertension (despite antihypertensive therapy and dose reduction). Risk of thromboembolic events. Untreated brain metastasis, recent active GI bleed: not recommended. Interrupt therapy if bleeding requires medical intervention. Monitor for signs/symptoms of cardiac failure during therapy; permanently discontinue if occurs. GI perforation and fistula formation; monitor. Monitor thyroid, liver function (ALT, AST, bilirubin), and for proteinuria before starting therapy, then periodically. Reduce dose or temporarily interrupt for moderate to severe proteinuria. Risk of reversible posterior leukoencephalopathy syndrome; discontinue if occurs. May impair wound healing; withhold dose for ≥2 days before elective surgery; do not give for ≥2 weeks after major surgery and until adequate wound healing. ESRD. Severe hepatic impairment: not studied. Embryo-fetal toxicity. Advise females of reproductive potential and males (w. female partners) to use effective contraception during and for 1 week after the last dose. Pregnancy: exclude status prior to initiation. Nursing mothers: not recommended (during and for 2 weeks after the last dose).
See Adults. Avoid strong CYP3A4/5 inhibitors (eg, grapefruit juice, ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole), CYP3A4/5 inducers (eg, rifampin, dexamethasone, phenytoin, carbamazepine, rifabutin, rifapentin, phenobarbital, St. John’s wort), moderate CYP3A4/5 inducers (eg, bosentan, efavirenz, etravirine, modafinil, nafcillin).
Diarrhea, nausea, vomiting, hypertension, fatigue, decreased appetite, dysphonia, palmar-plantar erythrodysesthesia (hand-foot) syndrome, weight decreased, asthenia, constipation.
Fecal (41%). Renal (23%). Half-life: 2.5–6.1 hours.
