Sotorasib is an orally available inhibitor of the specific KRAS mutation, p.G12C, with potential antineoplastic activity. Upon oral administration, sotorasib selectively targets, binds to and inhibits the activity of the KRAS p.G12C mutant. This may inhibit growth in KRAS p.G12C-expressing tumor cells. The KRAS p.G12C mutation is seen in some tumor cell types and plays a key role in tumor cell proliferation.

4 Drug and Medication Information
4.1 Drug Indication

Sotorasib is indicated in the treatment of adults with KRAS G12C mutant non small cell lung cancer.


Lumykras as monotherapy is indicated for the treatment of adults with advanced non-small cell lung cancer (NSCLC) with KRAS G12C mutation and who have progressed after at least one prior line of systemic therapy.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Sotorasib is indicated in the treatment of adults with KRAS G12C mutant non small cell lung cancer. It has a moderate duration of action as it is given daily. Patients should be counselled regarding the risks of hepatotoxicity, interstitial lung disease and pneumonitis; and to avoid breastfeeding during treatment and up to 1 week after the last dose.


5.2 MeSH Pharmacological Classification

Immune Checkpoint Inhibitors

Drugs that block negative regulator IMMUNE CHECKPOINT proteins (e.g., PD-1 RECEPTOR and CTLA-4 ANTIGEN) thereby increasing suppressed immune activation in immunotherapies. (See all compounds classified as Immune Checkpoint Inhibitors.)


5.3 ATC Code

L01XX73


L - Antineoplastic and immunomodulating agents

L01 - Antineoplastic agents

L01X - Other antineoplastic agents

L01XX - Other antineoplastic agents

L01XX73 - Sotorasib


5.4 Absorption, Distribution and Excretion

Absorption

A 960 mg once daily dose of sotorasib reaches a Cmax of 7.50 g/mL, with a median Tmax of 2.0 hours, and an AUC0-24h of 65.3 h\*g/mL.


Route of Elimination

Sotorasib is 74% eliminated in the feces and 6% eliminated in the urine. 53% of the dose recovered in the feces and 1% of the dose recovered in the urine is in the form of the unchanged parent compound.


Volume of Distribution

The volume of distribution of sotorasib is 211 L.


Clearance

Sotorasib has an apparent clearance at steady state of 26.2 L/h.


5.5 Metabolism/Metabolites

Sotorasib is predominantly metabolized through conjugation or by CYP3As.


5.6 Biological Half-Life

Sotorasib has a terminal elimination half life of 5.5 1.8 hours.


5.7 Mechanism of Action

Normally GTP binds to KRAS, activating the protein and promoting effectors to the MAP kinase pathway. GTP is hydrolyzed to GDP, and KRAS is inactivated. KRAS G12C mutations impair hydrolysis of GTP, leaving it in the active form. Sotorasib binds to the cysteine residue in KRAS G12C mutations, holding the protein in its inactive form. The cysteine residue that sotorasib targets is not present in the wild type KRAS, which prevents off-target effects. This mutation is present in 13% of non small cell lung cancer, 3% of colorectal and appendix cancer, and 1-3% of solid tumors.
