Interactions

7 DRUG INTERACTIONS Certain OCT2, MATE1, and MATE-2K substrates: Avoid concomitant use with certain OCT2, MATE1, and MATE-2K substrates where minimal concentration changes may lead to serious or life-threatening toxicities. ( 7.1 ) 7.1 Effect of COSELA on Other Drugs, Certain OCT2, MATE1, and MATE-2K Substrates COSELA is an inhibitor of OCT2, MATE1, and MATE-2K. Co-administration of COSELA may increase the concentration or net accumulation of OCT2, MATE1, and MATE-2K substrates in the kidney (e.g., dofetilide, dalfampridine, and cisplatin) [see Clinical Pharmacology ( 12.3 )]. Refer to the prescribing information for these concomitant medications for assessing the benefit and risk of concomitant use of COSELA.

Warnings

5 WARNINGS AND PRECAUTIONS Injection-Site Reactions, Including Phlebitis and Thrombophlebitis: Monitor for signs and symptoms of injection-site reactions, including phlebitis and thrombophlebitis during infusion. Stop infusion and permanently discontinue COSELA for severe or life-threatening reactions. ( 5.1 ) Acute Drug Hypersensitivity Reactions: Monitor for signs and symptoms of acute drug hypersensitivity reactions, including edema (facial, eye, and tongue), urticaria, pruritus, and anaphylactic reactions. Withhold COSELA for moderate reactions, and permanently discontinue for severe or life-threatening reactions. ( 5.2 ) Interstitial Lung Disease (ILD)/Pneumonitis: Patients treated with CDK4/6 inhibitors should be monitored for pulmonary symptoms indicative of ILD/pneumonitis. 4 CONTRAINDICATIONS COSELA is contraindicated in patients with a history of serious hypersensitivity reactions to trilaciclib. Reactions have included anaphylaxis [see Warnings and Precautions ( 5.2 )] . Patients with a history of serious hypersensitivity reactions to COSELA. ( 4 )

Pregnancy

8.1 Pregnancy Risk Summary Based on the mechanism of action, COSELA can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology ( 12 )] . There are no available human or animal data on COSELA use to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. 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. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.

Storage

16.2 Storage and Handling Store COSELA vials at 20°C to 25°C (68°F to 77°F); excursions are permitted to 15°C to 30°C (59°F to 86°F) [see USP Controlled Room Temperature] . The vial stopper is not made with natural rubber latex.
