Drug Detail:Kisqali (Ribociclib [ rye-boe-sye-klib ])
Generic Name: RIBOCICLIB SUCCINATE 200mg
Dosage Form: tablet, film coated
Drug Class: CDK 4/6 inhibitors
2.1 Dosing and Administration
The recommended dose of KISQALI is 600 mg (three 200 mg film-coated tablets) taken orally, once daily for 21 consecutive days followed by 7 days off treatment resulting in a complete cycle of 28 days. KISQALI can be taken with or without food [see Clinical Pharmacology (12.3)].
When given with KISQALI, refer to the Full Prescribing Information for the recommended dose of the aromatase inhibitor being used.
When given with KISQALI, the recommended dose of fulvestrant is 500 mg administered on Days 1, 15, 29, and once monthly thereafter. Please refer to the Full Prescribing Information of fulvestrant.
Pre/perimenopausal women, or men, treated with the combination KISQALI plus an aromatase inhibitor should be treated with a luteinizing hormone-releasing hormone (LHRH) agonist according to current clinical practice standards.
Men treated with the combination of KISQALI plus fulvestrant should be treated with a luteinizing hormone-releasing hormone (LHRH) agonist according to current clinical practice standards.
Patients should take their dose of KISQALI 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. KISQALI 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.

Refer to the Full Prescribing Information for the coadministered aromatase inhibitor or fulvestrant for dose modification guidelines in the event of toxicity and other relevant safety information.
Dose Modification for Use with Strong CYP3A Inhibitors
Avoid concomitant use of KISQALI 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), Clinical Pharmacology (12.3)].
Dose Modification for Hepatic Impairment
No dose adjustment 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 Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].
Review the Full Prescribing Information for the coadministered aromatase inhibitor or fulvestrant for dose modifications related to hepatic impairment.
Dose Modification for Renal Impairment
No dose adjustment is necessary in patients with mild or moderate renal impairment. The recommended starting dose is 200 mg KISQALI once daily for patients with severe renal impairment [see Use in Specific Populations (8.7), Clinical Pharmacology (12.3)].
