Dosing and Administration
The KISQALI FEMARA CO-PACK is comprised of ribociclib tablets copackaged with letrozole tablets, to provide a 28-day treatment regimen.
The KISQALI FEMARA CO-PACK should be coadministered, with or without food, as follows:
- KISQALI: The recommended starting dose for KISQALI is 600 mg (three 200 mg tablets) taken orally, once daily for 21 consecutive days followed by 7 days off KISQALI treatment resulting in a complete cycle of 28 days.
- FEMARA: 2.5 mg (one tablet) taken once daily throughout the 28-day cycle.
Patients should take their doses of KISQALI FEMARA CO-PACK at approximately the same time each day, preferably in the morning. If the patient vomits after taking the dose or misses a dose, no additional dose should be taken that day. The next prescribed dose should be taken at the usual time. Tablets should be swallowed whole (tablets should not be chewed, crushed or split prior to swallowing). No tablet should be ingested if it is broken, cracked, or otherwise not intact.
For additional information on KISQALI® and FEMARA®, refer to the Full Prescribing Information for each product.

|Perform Liver Function Tests (LFTs) before initiating treatment with KISQALI.
Monitor LFTs every 2 weeks for the first 2 cycles, at the beginning of each subsequent 4 cycles, and as clinically indicated.
If Grade ≥2 abnormalities are noted, more frequent monitoring is recommended.

|Electrocardiograms (ECGs) should be assessed prior to initiation of treatment. Repeat ECGs at approximately Day 14 of the first cycle and at the beginning of the second cycle, and as clinically indicated.
In case of (QTcF) prolongation at any given time during treatment, more frequent ECG monitoring is recommended.

Dose Modification for Use with Strong CYP3A Inhibitors
Avoid concomitant use of KISQALI FEMARA CO-PACK with strong CYP3A inhibitors and consider an alternative concomitant medication with less potential for CYP3A inhibition [see Drug Interactions (7.1)]. If a strong CYP3A inhibitor must be coadministered, reduce the KISQALI dose to 400 mg once daily. If the strong inhibitor is discontinued, change the KISQALI dose (after at least 5 half-lives of the strong CYP3A inhibitor) to the dose used prior to the initiation of the strong CYP3A inhibitor [see Drug Interactions (7.1) and Clinical Pharmacology (12.3)].
Dose Modification for Hepatic Impairment
No dose adjustment of KISQALI is necessary in patients with mild hepatic impairment (Child-Pugh class A). The recommended starting dose is 400 mg KISQALI once daily for patients with moderate (Child-Pugh class B) and severe hepatic impairment (Child-Pugh class C) [see Clinical Pharmacology (12.3)].
No dose adjustment of FEMARA is necessary in patients with mild (Child-Pugh class A) to moderate (Child-Pugh class B) hepatic impairment. The dose of FEMARA in patients with cirrhosis and severe hepatic dysfunction should be reduced by 50% [see Clinical Pharmacology (12.3)]. The recommended dose of FEMARA for such patients is 2.5 mg administered every other day. The effect of hepatic impairment on FEMARA exposure in noncirrhotic cancer patients with elevated bilirubin levels has not been determined [see Clinical Pharmacology (12.3)].
