Trisela Injection 300 mg/vial

Trisela Injection 300 mg/vial Uses, Dosage, Side Effects, Food Interaction and all others data.

Trisela Injection 300 mg/vial, or G1T28, is a CDK4 and CDK6 inhibitor, indicated to reduce the incidence of chemotherapy induced myelosuppression in patients before topotecan-containing or platinum and etoposide-containing chemotherapy for extensive stage small cell lung cancer. CDK4 and CDK6 inhibitors have been investigated since the mid 1990s for their use in tumorigenesis and chemotherapy. Trisela Injection 300 mg/vial was first described in the literature in 2016.

Trisela Injection 300 mg/vial was granted FDA approval on 12 February 2021.

Trisela Injection 300 mg/vial is indicated to reduce the incidence of chemotherapy induced myelosuppression in patients prior to receiving platinum and etoposide-containing or topotecan-containing chemotherapy regimens for extensive-stage small cell lung cancer. It has a short duration of action of approximately 16 hours, and a narrow therapeutic index. Patients should be counselled regarding the risk of injection site reactions, hypersensitivity, and interstitial lung disease.

Uses

Trisela Injection 300 mg/vial is a CDK4 and CDK6 inhibitor to reduce the risk of chemotherapy induced myelosuppression.

Trisela Injection 300 mg/vial is indicated to reduce the incidence of chemotherapy induced myelosuppression in patients prior to receiving platinum and etoposide-containing or topotecan-containing chemotherapy regimens for extensive-stage small cell lung cancer.

Trisela Injection 300 mg/vial is also used to associated treatment for these conditions: Bone Marrow Suppression caused by Chemotherapy

How Trisela Injection 300 mg/vial works

Trisela Injection 300 mg/vial is inhibits cyclin-dependant kinase 4 (CDK4) at a concentration of 1 nmol/L and cyclin-dependent kinase 5 (CDK5) at 4 nmol/L. Inhibition of CDK2, CDK5, and CDK7 is over 1000-fold less at these concentrations and inhibition of CDK9 is 50-fold less.

CDK4 and CDK5 are expressed in hematopoietic stem cells and progenitor cells. They are capable of phosphorylating and inactivating the retinoblastoma protien; a tumor suppressor. When trilaciclib is given to patients with retinoblastoma protein-null small cell lung cancer, it does not interfere with the intended chemotherapy induced cytotoxicity of cancer cells. Inhibition of CDK4 and CDK5 leads to a reversible pause in the cell cycle in the G1 phase for approximately 16 hours. The temporary cell cycle arrest prevents chemotherapy induced DNA damage in healthy cells, reducing the activity of caspases 3 and 7, which reduces apoptosis of healthy cells.

Other studies have shown inhibitors of CDK4 and CDK6 enhance T-cell activation, upregulating major histocompatibility complex (MHC) class I and II, and stabilize programmed death-ligand 1 (PD-L1). Together these activities increase T-cell activity, increase antigen presentation, and sensitize cells to immune checkpoint inhibitors.

Toxicity

Data regarding overdoses of trilaciclib are not readily available. For grade 3 or worse injection site reactions, acute drug hypersensitivity reactions, and interstitial lung disease; or any other grade 4 toxicities; permanently discontinue trilacilib.
