Important Safety Information
This is not a complete list of all possible side effects. Contact your healthcare provider if you experience any unexpected symptoms. For serious or life-threatening side effects, seek emergency medical attention immediately.
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the label: Injection-Site Reactions, including phlebitis and thrombophlebitis [ s ee Warnings and Precautions ( 5.1 )] Acute Drug Hypersensitivity Reactions [see Warnings and Precautions ( 5.2 )] ILD/Pneumonitis [see Warnings and Precautions ( 5.3 )] The most common adverse reactions (≥10% of patients with ≥2% difference in incidence compared to placebo) were fatigue, hypocalcemia, hypokalemia, hypophosphatemia, aspartate aminotransferase increased, headache, and pneumonia.

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 with rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The safety of COSELA was evaluated in Studies 1, 2, and 3 [see Clinical Studies ( 14 )] .
Patients received COSELA 240 mg/m 2 by 30-minute intravenous infusion prior to chemotherapy on each chemotherapy day.
The data described in this section reflect exposure to COSELA among 240 patients (122 patients in the trilaciclib group and 118 patients in the placebo group) being treated for extensive stage-small cell lung cancer (ES-SCLC) in 3 randomized, double-blind, placebo-controlled trials: 32 patients with treatment naïve ES-SCLC received carboplatin (AUC 5 Day 1) + etoposide (100 mg/m 2 Days 1-3) every 21 days;
58 received carboplatin (AUC 5 Day 1) + etoposide (100 mg/m 2 Days 1-3) every 21 days + atezolizumab (1200 mg on Day 1) every 21 days;
32 patients with previously treated ES-SCLC received topotecan (1.5 mg/m 2 Days 1-5) every 21 days.
Study 1: COSELA Prior to Etoposide, Carboplatin, and Atezolizumab (E/P/A) Patients with newly diagnosed ES-SCLC not previously treated with chemotherapy Study 1 (G1T28-05;
NCT03041311) was an international, randomized (1:1), double-blind, placebo-controlled study of COSELA or placebo administered prior to treatment with etoposide, carboplatin, and atezolizumab (E/P/A) for patients with newly diagnosed ES-SCLC not previously treated with chemotherapy.
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.
Like all medications, Cosela can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
