Vorasidenib: uses, dosing, side effects & brands

The following clinically significant adverse reactions are described elsewhere in the labeling: Hepatotoxicity [see Warnings and Precautions (5.1) ] The most common (≥15%) adverse reactions include fatigue, headache, COVID-19, musculoskeletal pain, diarrhea, nausea, and seizure. Grade 3 or 4 (≥2%) laboratory abnormalities were ALT increased, AST increased, GGT increased, and neutrophils decreased. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Servier Pharmaceuticals at 1-800-807-6124 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse reactions described in the WARNINGS AND PRECAUTIONS reflect exposure to VORANIGO 40 mg orally once daily until disease progression or unacceptable toxicity in the 244 patients with astrocytoma or oligodendroglioma with susceptible IDH1 or IDH2 mutation in trials AG881-C-002 (NCT02481154, n=11), AG120-881-001 (NCT03343197, n=14) and INDIGO (NCT04164901, n=167 randomized patients and n=52 crossover patients). Among the 244 patients who received VORANIGO, 78% were exposed for 6 months or longer and 44% were exposed for greater than one year. In…

CYP1A2 Inhibitors : Avoid concomitant use of strong and moderate CYP1A2 inhibitors. ( 7.1 ) CYP1A2 Inducers : Avoid concomitant use of moderate CYP1A2 inducers and smoking tobacco. ( 7.1 ) Certain CYP3A Substrates : Avoid concomitant use with CYP3A substrates, where a minimal concentration change can reduce efficacy. ( 7.2 ) Hormonal Contraception : If concomitant use cannot be avoided, use with nonhormonal contraception methods. ( 7.2 ) 7.1 Effect of Other Drugs on VORANIGO Table 5: Effect of Other Drugs on VORANIGO Strong and Moderate CYP1A2 Inhibitors Clinical Impact Concomitant use of VORANIGO with a strong or moderate CYP1A2 inhibitor may increase vorasidenib plasma concentrations [see Clinical Pharmacology (12.3) ] , which may increase the risk of adverse reactions. Prevention or Management Avoid concomitant use of VORANIGO with strong and moderate CYP1A2 inhibitors. If concomitant use of moderate CYP1A2 inhibitors cannot be avoided, monitor for increased adverse reactions and modify the dosage for adverse reactions as recommended [see Dosage and Administration (2.4) ] . Moderate CYP1A2 Inducers Clinical Impact Concomitant use of VORANIGO with moderate CYP1A2 inducers and smoking tobacco may decrease vorasidenib plasma concentrations [see Clinical Pharmacology (12.3) ] , which may reduce the anti-tumor activity of VORANIGO. Prevention or Management Avoid concomitant use of VORANIGO with moderate CYP1A2 inducers and smoking tobacco. 7.2 Effect of VORANIGO on Other Drugs Table 6: Effect of VORANIGO on Other Drugs Certain CYP3A Substrates Clinical Impact Concomitant use of VORANIGO with CYP3A substrates may decrease plasma concentrations of CYP3A substrates [see Clinical Pharmacology (12.3) ] . Prevention or Management Avoid concomitant use of VORANIGO with CYP3A substrates, where a minimal concentration change may lead to reduced therapeutic effect. Hormonal Contraception Clinical Impact Concomitant use of VORANIGO may decrease the concentrations of hormonal contraceptives, which may lead to contraception failure and/or an increase in breakthrough bleeding [see Clinical Pharmacology (12.3) ] . Prevention or Management If concomitant use cannot be avoided, use with nonhormonal contraception methods.
