Side Effects

SIDE EFFECTS

The following clinically significant adverse reactions are described elsewhere in the label:

  • Injection-Site Reactions, including phlebitis and thrombophlebitis [see WARNINGS AND PRECAUTIONS]
  • Acute Drug Hypersensitivity Reactions [see WARNINGS AND PRECAUTIONS]
  • ILD/Pneumonitis [see WARNINGS AND PRECAUTIONS]

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]. Patients received COSELA 240 mg/m² 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 naive ES-SCLC received carboplatin (AUC 5 Day 1) + etoposide (100 mg/m² Days 1-3) every 21 days; 58 received carboplatin (AUC 5 Day 1) + etoposide (100 mg/m² 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/m² 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. The data presented below are for the 105 patients who received study treatment.

Eighty-five percent of patients receiving COSELA and 91% receiving placebo completed 4 cycles of induction therapy.

Study 2: COSELA Prior To Etoposide And Carboplatin (E/P)

Patients With Newly Diagnosed ES-SCLC Not Previously Treated With Chemotherapy

Study 2 (G1T28-02; NCT02499770) was an international, randomized (1:1), double-blind, placebo-controlled study of COSELA or placebo administered prior to treatment with etoposide and carboplatin (E/P) for patients with newly diagnosed ES-SCLC not previously treated with chemotherapy. The data presented below are for the 75 patients who received study treatment.

Seventy-six percent of patients in the COSELA group and 87% of patients in the placebo group completed at least 4 cycles of therapy. The median duration of treatment was 6 cycles in each treatment group.

Study 3: COSELA Prior To Topotecan

Patients With ES-SCLC Previously Treated With Chemotherapy

Study 3 (G1T28-03; NCT02514447) was an international, randomized (2:1), double-blind, placebo-controlled study of COSELA or placebo administered prior to treatment with topotecan for patients with ES-SCLC previously treated with chemotherapy. The data presented below are for the 60 patients who received study treatment with the 1.5 mg/m² dose of topotecan.

Thirty-eight percent of patients receiving COSELA and 29% of patients receiving placebo completed 5 or more cycles of therapy. The median duration of treatment was 3 cycles in each treatment group.

Drug Interactions

DRUG INTERACTIONS

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].

Refer to the prescribing information for these concomitant medications for assessing the benefit and risk of concomitant use of COSELA.

Table 4: Potentially Significant Drug Interactions with COSELA

DrugsRecommendationsComments
DofetilideThe potential benefits of taking COSELA concurrently with dofetilide should be considered against the risk of QT interval prolongation.Increased dofetilide blood levels may occur in patients who are also receiving COSELA. Increased plasma concentrations of dofetilide may cause serious ventricular arrhythmias associated with QT interval prolongation, including torsade de pointes.
DalfampridineThe potential benefits of taking COSELA concurrently with dalfampridine should be considered against the risk of seizures in these patients.Increased dalfampridine blood levels may occur in patients who are also receiving COSELA. Elevated levels of dalfampridine increase the risk of seizure.
CisplatinClosely monitor for nephrotoxicity.Concurrent treatment with COSELA may increase the exposure and alter the net accumulation of cisplatin in the kidney, which may associate with dose-related nephrotoxicity.

Warnings & Precautions

WARNINGS

Included as part of the PRECAUTIONS section.

PRECAUTIONS

Injection-Site Reactions, Including Phlebitis And Thrombophlebitis

COSELA administration can cause injection-site reactions including phlebitis and thrombophlebitis. Injection-site reactions including phlebitis and thrombophlebitis occurred in 56 (21%) of 272 patients receiving COSELA in clinical trials, including Grade 2 (10%) and Grade 3 (0.4%) adverse reactions (ARs). The median time to onset from start of COSELA was 15 days (range 1 to 542) and from the preceding dose of COSELA was 1 day (1 to 15).The median duration was 1 day (range 1 to 151 for the resolved cases). Injection-site reactions including phlebitis and thrombophlebitis resolved in 49 (88%) of the 56 patients and led to discontinuation of treatment in 3 (1%) of the 272 patients.

Monitor patients for signs and symptoms of injection-site reactions, phlebitis, and thrombophlebitis, including infusion-site pain and erythema during infusion. For mild (Grade 1) to moderate (Grade 2) injection-site reactions, flush line/cannula with at least 20 mL of sterile 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP after end of infusion. For severe (Grade 3) or life-threatening (Grade 4) injection-site reactions, stop infusion and permanently discontinue COSELA [see DOSAGE AND ADMINISTRATION].

Acute Drug Hypersensitivity Reactions

COSELA administration can cause acute drug hypersensitivity reactions, including facial edema and urticaria. Acute drug hypersensitivity reactions occurred in 16 (6%) of 272 patients receiving COSELA in clinical trials, including Grade 2 reactions (2%). One patient experienced a Grade 2 anaphylactic reaction 4 days after receiving COSELA, which resolved with epinephrine, and treatment with COSELA was continued. The median time to onset from start of COSELA was 77 days (range 2 to 256) and from the preceding dose of COSELA was 1 day (range 1 to 28). The median duration was 6 days (range 1 to 69 for the resolved cases). Acute drug hypersensitivity reactions resolved in 12 (75%) of the 16 patients.

Monitor patients for signs and symptoms of acute drug hypersensitivity reactions including facial, eye, and tongue edema, urticaria, pruritus, and anaphylactic reactions. For moderate (Grade 2) acute drug hypersensitivity reactions, stop infusion and hold COSELA until the adverse reaction recovers to Grade ≤1. For severe (Grade 3) or life-threatening (Grade 4) acute drug hypersensitivity reactions, stop infusion and permanently discontinue COSELA [see DOSAGE AND ADMINISTRATION].

Interstitial Lung Disease/Pneumonitis

Severe, life-threatening, or fatal interstitial lung disease (ILD) and/or pneumonitis can occur in patients treated with cyclin-dependent kinases (CDK)4/6 inhibitors, the same drug class as COSELA. ILD/pneumonitis occurred in 1 (0.4%) of 272 patients receiving COSELA in clinical trials. The adverse reaction was Grade 3 and reported 2 months after discontinuing COSELA, in a patient receiving a confounding medication. The adverse reaction did not resolve.

Monitor patients for pulmonary symptoms indicative of ILD/pneumonitis such as cough, dyspnea, and hypoxia. For recurrent moderate (Grade 2) ILD/pneumonitis, permanently discontinue COSELA. For severe (Grade 3) or life-threatening (Grade 4) ILD/pneumonitis, permanently discontinue COSELA [see DOSAGE AND ADMINISTRATION].

Embryo-Fetal Toxicity

Based on its mechanism of action, COSELA can cause fetal harm when administered to a pregnant woman. Females of reproductive potential should use an effective method of contraception during treatment with COSELA and for at least 3 weeks after the final dose [see Use In Specific Populations].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Carcinogenesis studies have not been conducted with trilaciclib.

Trilaciclib was negative for mutagenic potential in a bacterial reverse mutation (Ames) assay and negative for clastogenic potential in an in vitro histone H2AX phosphorylation assay in primary human fibroblasts. Trilaciclib increased the frequency of micronucleus formation in human lymphocytes in vitro. Clastogenic potential of trilaciclib was not assessed in vivo.

Fertility studies have not been performed to evaluate the effects of trilaciclib. Treatment with trilaciclib in female rats and dogs resulted in reductions in mean ovary and uterus weights at clinically relevant exposures, which were reversible after a two-week drug-free recovery period.

Use In Specific Populations

Pregnancy

Risk Summary

Based on the mechanism of action, COSELA can cause fetal harm when administered to a pregnant woman [see CLINICAL PHARMACOLOGY]. 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. However, the background risk of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies in the United States general population.

Lactation

Risk Summary

There are no data on the presence of trilaciclib in either human or animal milk, the effects on the breastfed child or the effects on milk production. Because of the potential for serious adverse reactions in breastfed children, advise lactating women to not breastfeed while taking COSELA and for at least 3 weeks after the last dose.

Females And Males Of Reproductive Potential

Pregnancy Testing

Based on its mechanism of action, COSELA can cause fetal harm if administered to a pregnant woman [see Use In Specific Populations]. Pregnancy testing is recommended for females of reproductive potential prior to initiating COSELA.

Contraception

COSELA can cause fetal harm when administered to pregnant women [see Use In Specific Populations]. Advise female patients of reproductive potential to use effective contraception during treatment with COSELA and for at least 3 weeks after the final dose.

Infertility

No studies have been performed in humans to evaluate the effects of COSELA on fertility in either sex.

Based on animal toxicology studies, COSELA may impair fertility in females of reproductive potential [see Nonclinical Toxicology].

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

In the pooled efficacy dataset from Studies 1, 2, and 3, 46% of 123 patients randomized to COSELA were ≥65 years of age, and 49% of 119 patients randomized to placebo were ≥65 years of age. No overall differences in safety or effectiveness of COSELA were observed between these patients and younger patients.

Hepatic Impairment

Use of COSELA is not recommended in patients with moderate or severe hepatic impairment. No dosage adjustment is recommended for patients with mild hepatic impairment (total bilirubin ≤ upper limit of normal [ULN] and aspartate aminotransferase [AST] > ULN, or total bilirubin >1.0 to 1.5 × ULN, irrespective of AST). The pharmacokinetics of COSELA have not been studied in patients with moderate or severe hepatic impairment (total bilirubin >1.5 × ULN, irrespective of AST) [see CLINICAL PHARMACOLOGY].
