Drug Interactions
7 DRUG INTERACTIONS CYP3A Inhibitors: Avoid concomitant use of KISQALI with strong CYP3A inhibitors. If strong inhibitors cannot be avoided, reduce KISQALI dose. ( 2.2 , 7.1 ) CYP3A4 Inducers: Avoid concomitant use of KISQALI with strong CYP3A inducers. ( 7.2 ) CYP3A Substrates: The dose of CYP3A substrates may need to be reduced when given concurrently with KISQALI. ( 7.3 ) Drugs Known to Prolong QT Interval: Avoid concomitant use of drugs known to prolong QT interval, such as anti-arrhythmic medicines. ( 7.4 ) 7.1 Drugs That May Increase Ribociclib Plasma Concentrations CYP3A4 Inhibitors Coadministration of strong CYP3A inhibitors increases ribociclib exposure [see Clinical Pharmacology (12.3)] . Increased ribociclib concentrations may increase the incidence and severity of adverse reactions, including QTcF prolongation [see Warnings and Precautions (5.3)] . Avoid concomitant use of strong CYP3A inhibitors with KISQALI and consider alternative concomitant medications with less potential for CYP3A inhibition. In patients with early breast cancer, if coadministration of KISQALI with a strong CYP3A inhibitor cannot be avoided, reduce the dose of KISQALI to 200 mg once daily. In patients with advanced or metastatic breast cancer, if coadministration of KISQALI with a strong CYP3A inhibitor cannot be avoided, reduce the dose of KISQALI to 400 mg once daily [see Dosage and Administration (2.2)] . 7.2 Drugs That May Decrease Ribociclib Plasma Concentrations CYP3A Inducers Coadministration of strong CYP3A inducers decreases the plasma exposure of ribociclib [see Clinical Pharmacology (12.3)] . Avoid concomitant use of strong CYP3A inducers and consider an alternate concomitant medication with no or minimal potential to induce CYP3A. 7.3 Effect of KISQALI on Other Drugs CYP3A Substrates Coadministration of sensitive CYP3A4 substrates with multiple doses of KISQALI increases the substrate exposure [see Clinical Pharmacology (12.3)] . For CYP3A substrates where minimal increases in the concentration may increase CYP3A substrate adverse reactions, monitor for increased adverse reactions of the CYP3A substrate during treatment with KISQALI. The dose of the sensitive CYP3A substrate may need to be reduced as KISQALI can increase its exposure. 7.4 Drugs That Prolong the QT Interval Avoid coadministration of KISQALI with products with a known potential to prolong QT interval, such as antiarrhythmic drugs and other drugs that are known to prolong the QT interval. If concomitant use cannot be avoided, monitor ECG when initiating, during concomitant use, and as clinically indicated [see Warnings and Precautions (5.3), Clinical Pharmacology (12.2)] .

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Based on findings from animal studies and the mechanism of action, KISQALI can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)] . There are no available human data informing the drug-associated risk. In animal reproduction studies, administration of ribociclib to pregnant animals during organogenesis resulted in increased incidences of post implantation loss and reduced fetal weights in rats and increased incidences of fetal abnormalities in rabbits at exposures 0.6 or 1.5 times the exposure in humans, respectively, at the highest recommended dose of 600 mg/day based on AUC (see Data) . Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. However, the background risk of major birth defects is 2%-4% and of miscarriage is 15%-20% of clinically recognized pregnancies in the U.S. general population. Data Animal Data In embryo-fetal development studies in rats and rabbits, pregnant animals received oral doses of ribociclib up to 1000 mg/kg/day and 60 mg/kg/day, respectively, during the period of organogenesis. In rats, 300 mg/kg/day resulted in reduced maternal body weight gain and reduced fetal weights accompanied by skeletal changes related to the lower fetal weights. There were no significant effects on embryo-fetal viability or fetal morphology at 50 or 300 mg/kg/day. In rabbits at doses ≥ 30 mg/kg/day, there were adverse effects on embryo-fetal development, including increased incidences of fetal abnormalities (malformations and external, visceral, and skeletal variants) and fetal growth (lower fetal weights). These findings included reduced/small lung lobes, additional vessel on the descending aorta, additional vessel on the aortic arch, small eyes, diaphragmatic hernia, absent accessory lobe or (partly) fused lung lobes, reduced/small accessory lung lobe, extra/rudimentary 13 th ribs, misshapen...
