History of serious hypersensitivity to trilaciclib
Cautions
Severe, life-threatening, or fatal interstitial lung disease (ILD) and/or pneumonitis reported with cyclin-dependent kinases (CDK)4/6 inhibitors, including trilaciclib; monitor for symptoms (eg, cough, dyspnea, hypoxia)
May cause fetal harm
Injection-site reactions
- Injection-site reactions (eg, phlebitis, thrombophlebitis) may occur
- Median time to onset: 15 days (from initiation); 1 day (preceding dose)
- Median duration: 1 day
- Monitor for signs and symptoms, including infusion-site pain and erythema during infusion
Acute drug hypersensitivity reactions
- May cause acute drug hypersensitivity reactions, including facial edema and urticaria

Drug interaction overview
- Inhibitor of OCT2, MATE1, MATE-2K
-
Certain OCT2, MATE1, and MATE-2K substrates
- Avoid coadministration
- Trilaciclib may increase plasma and/or kidney concentrations of certain OCT2, MATE1, and MATE-2K substrates (eg, dofetilide, dalfampridine, cisplatin)

Pregnancy & Lactation
Pregnancy
Based on mechanism of action, fetal harm may occur when administer to pregnant females
No human or animal data are available
Advise pregnant females of potential risks to fetus
Pregnancy test recommended in females of reproductive potential
Contraception
- Females of reproductive potential: Use effective contraception during treatment and for at least 3 weeks after final dose
Infertility
- No studies performed
- Based on animal studies, fertility may be impaired in females of reproductive potential
Lactation
No data are available
Advise to not breastfeed during treatment and for at least 3 weeks after last dose
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Transient CDK 4/6 inhibitor
Hematopoietic stem and progenitor cells (HSPC) in the bone marrow give rise to circulating neutrophils, red blood cells, and platelets
HSPC proliferation is dependent on CDK4/6 activity
Distribution
Blood-to-plasma ratio:1.21-1.53
Vd: 1,130 L
Metabolism
Extensively metabolized
Trilaciclib is the predominantly circulating compound in plasma following IV administration, representing ~50% of plasma total radioactivity
Elimination
Half-life: ~14 hr
Estimated clearance: 158 L/hr
Excretion: Feces (79.1% [7% unchanged]); urine (14% [2% unchanged])
Administration
IV Compatibilities
D5W
0.9% NaCl
IV Preparation
Reconstitution
- Calculate dose, total drug volume, and number of vials needed
- Reconstitute each 300-mg vial with 19.5 mL of 0.9% NaCl or D5W, obtaining a concentration of 15 mg/mL
- Gently swirl vial for up to 3 min until sterile lyophilized cake completely dissolves; do not shake
- Visually inspect for discoloration and particulate matter; reconstituted solution should be a clear, yellow solution; discard if discolored, cloudy, or contains visible particulates
Dilution
- Withdraw required dosage volume from reconstituted vial(s); dilute into 0.9% NaCl or D5W IV infusion bag to obtain final concentration of 0.5-3 mg/mL
- Gently invert diluted solution to mix; do not shake
- Visually inspect for particulate matter and discoloration; diluted solution is a clear, yellow solution
IV Administration
Infuse over 30 min
Complete infusion within 4 hr before starting chemotherapy
Administer with an infusion set, including an in-line 0.2- or 0.22-micron filter; compatible in-line filters include polyethylene sulfone, polyvinylidene fluoride, and cellulose acetate
Flush infusion line/cannula with sterile 0.9% NaCl or D5W once infusion completes
Do NOT administer or coadminister with
- Polytetrafluorethylene (PTFE) in-line filters: Diluted solutions are incompatible with PTFE in-line filters
- Other drugs through same infusion line
- Other drugs through a central access device unless device supports coadministration of incompatible drug(s)
Missed dose
- Discontinue chemotherapy on day dose was missed
- Consider resuming both trilaciclib and chemotherapy on next scheduled chemotherapy
Discontinuing treatment
- Wait 96 hr from last trilaciclib dose before resumption of chemotherapy only
