Ripretinib

Identification

Summary

Ripretinib is a kinase inhibitor used to treat advanced gastrointestinal stromal tumor (GIST).

Brand Names
Qinlock
Generic Name
Ripretinib
DrugBank Accession Number
DB14840
Background

Ripretinib is a kinase inhibitor used for the treatment of advanced gastrointestinal stromal tumor (GIST) that has not adequately responded to other kinase inhibitors such as sunitinib and imatinib. Ripretinib, also known as Qinlock, is manufactured by Deciphera Pharmaceuticals and was initially approved by the FDA on May 15, 2020.7

It is the first drug approved as a fourth-line therapy in the specific setting of prior treatment with a minimum of 3 other kinase inhibitors.8

Pharmacodynamics

As a broad-spectrum kinase inhibitor, ripretinib inhibits various gene mutations, increasing progression-free survival in patients with advanced gastrointestinal stromal tumors (GIST).10,11 It is effective in treating mutations that are resistant to chemotherapy with other kinase inhibitors, such as imatinib.7

Ripretinib has the propensity to cause cardiac dysfunction and new primary cutaneous malignancy. It is important to measure cardiac ejection fraction before and during treatment as well as to perform regular dermatological assessments.7

Mechanism of action

Protein kinases play important roles in cellular function, and their dysregulation can lead to carcinogenesis.4 Ripretinib inhibits protein kinases including wild type and mutant platelet-derived growth factor receptor A (PDGFRA) and KIT that cause the majority of gastrointestinal stromal tumor (GIST).5 In vitro, ripretinib has been shown to inhibit PDGFRB, BRAF, VEGF, and TIE2 genes.2,3,7

Ripretinib binds to KIT and PDGFRA receptors with mutations on the exons 9, 11, 13, 14, 17 and 18 (for KIT mutations), and exons 12, 14 and 18 (for PDGFRA mutations).1 The “switch pocket” of a protein kinase is normally bound to the activation loop, acting as an “on-off switch” of a kinase. Ripretinib boasts a unique dual mechanism of action of binding to the kinase switch pocket as well as the activation loop, thereby turning off the kinase and its ability to cause dysregulated cell growth.1,9

Absorption

Ripretinib is absorbed in the gastrointestinal tract and Tmax is achieved in 4 hours, with steady-state concentrations reached within 14 days.7

Volume of distribution

The mean volume of distribution of ripretinib is 307 L.7

Protein binding

Ripretinib is over 99% bound to albumin and alpha-1 acid glycoprotein. 7

Metabolism

Ripretinib is metabolized by the CYP3A subfamily of enzymes with contributions from CYP2D6 and CYP2E1 to its active metabolite, DP-5439.7

Half-life

The average half-life of ripretinib is 14.8 hours.7

Clearance

The mean apparent clearance of ripretinib is 15.3 L/hour.7

Toxicity

There is limited information in the literature regarding an overdose with ripretinib, and LD50 information is not readily available.7 Like other kinase inhibitors, an overdose with ripretinib likely results in hematological toxicity, skin toxicity, as well as muscle, liver, and gastrointestinal toxicity.6,7
