Ripretinib is an inhibitor of KIT and PDGFRα (IC50s = 3 and 3.6 nM, respectively).1 It is selective for KIT and PDGFRα over a panel of 300 kinases (IC50s = >100 nM) but does inhibit DDR2, VEGFR2, PDGFRβ, and Tie2 (IC50s = <10 nM for all). It also inhibits mutant isoforms of KIT and PDGFRα, including KITV654A, KITT670I, KITD816H, KITD816V, and PDGFRαD842V (IC50s = 11, 9.2, 18, 25, and 36 nM, respectively). Ripretinib induces apoptosis in ROSA wild-type, and KITD816V- or KITK509I-expressing mast cells in a concentration-dependent manner.2 It reduces tumor growth and increases survival in an imatinib-resistant patient-derived xenograft (PDX) mouse model of gastrointestinal stromal tumors (GISTs) when administered at doses of 50 and 100 mg/kg.1 Formulations containing ripretinib have been used in the treatment of GISTs.

Ripretinib: First Approval
Drugs 2020 Jul;80(11):1133-1138.PMID:32578014DOI:10.1007/s40265-020-01348-2.
Ripretinib (QINLOCK™) is a novel type II tyrosine switch control inhibitor being developed by Deciphera Pharmaceuticals for the treatment of KIT proto-oncogene receptor tyrosine kinase (KIT)-driven and/or platelet derived growth factor receptor A (PDGFRA)-driven cancers, including gastrointestinal stromal tumour (GIST). Ripretinib inhibits KIT and PDGFRA kinase, including wild-type, primary and secondary mutations, as well as other kinases, such as PDGFRB, TIE2, VEGFR2 and BRAF. In May 2020, oral Ripretinib received its first approval in the USA for the treatment of adult patients with advanced GIST who have received prior treatment with ≥ 3 kinase inhibitors, including imatinib. The US FDA, Health Canada and the Australian Therapeutic Goods Administration collaborated on the review of the Ripretinib new drug application in this indication as part of Project Orbis; regulatory review in Australia and Canada is ongoing. Clinical development for GIST, solid tumours and systemic mastocytosis is underway in several countries worldwide. This article summarizes the milestones in the development of Ripretinib leading to this first approval for the treatment of advanced GIST.
Ripretinib: A Review in Gastrointestinal Stromal Tumours as Fourth-or Later-Line of Therapy
Drugs 2022 Oct;82(15):1541-1548.PMID:36282417DOI:10.1007/s40265-022-01794-0.
Ripretinib (Qinlock®) is a small molecule inhibitor of the receptor tyrosine kinases KIT and platelet-derived growth factor receptor α (PDGFRA) and is approved for the treatment of gastrointestinal stromal tumours as a fourth-line of therapy. After successive cycles of treatment, gastrointestinal stromal tumours can carry a wide array of mutations, which makes resistance to treatment more likely. Ripretinib has a dual mechanism of action that allows it to target a broad spectrum of mutations in KIT or PDGFRA. The pivotal phase III INVICTUS trial demonstrated an increase of progression-free survival in patients receiving Ripretinib compared with placebo, with efficacy being maintained across patients with KIT exon 9, 11, 13 and 17 mutations. Ripretinib has acceptable tolerability, with the most common drug-related grade 3 or 4 adverse events being lipase increases, hypertension, fatigue and hypophosphataemia. Ripretinib is therefore a valuable additional line of therapy available for the management of gastrointestinal stromal tumours.
Ripretinib in patients with advanced gastrointestinal stromal tumours (INVICTUS): a double-blind, randomised, placebo-controlled, phase 3 trial
Lancet Oncol 2020 Jul;21(7):923-934.PMID:32511981DOI:10.1016/S1470-2045(20)30168-6.
Background: Resistance to approved inhibitors of KIT proto-oncogene, receptor tyrosine kinase (KIT), and platelet-derived growth factor receptor α (PDGFRA) is a clinical challenge for patients with advanced gastrointestinal stromal tumours. We compared the efficacy and safety of Ripretinib, a switch-control tyrosine kinase inhibitor active against a broad spectrum of KIT and PDGFRA mutations, with placebo in patients with previously treated, advanced gastrointestinal stromal tumours. Methods: In this double-blind, randomised, placebo-controlled, phase 3 study, we enrolled adult patients in 29 specialised hospitals in 12 countries. We included patients aged 18 years or older who had advanced gastrointestinal stromal tumours with progression on at least imatinib, sunitinib, and regorafenib or documented intolerance to any of these treatments despite dose modifications, and who had an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2. Eligible patients were randomly assigned (2:1) to receive either oral Ripretinib 150 mg once daily (ripretenib group) or placebo once daily (placebo group). Randomisation was done via an interactive response system using randomly permuted block sizes of six and stratified according to number of previous therapies and ECOG performance status. Patients, investigators, research staff, and the sponsor study team were masked to a patient's treatment allocation until the blinded independent central review (BICR) showed progressive disease for the patient. The primary endpoint was progression-free survival, assessed by BICR. The primary analysis was done in the intention-to-treat population and safety was assessed in patients who received at least one dose of study drug. Patients randomly assigned to placebo were permitted to cross over to Ripretinib 150 mg at the time of disease progression. The INVICTUS study is registered with ClinicalTrials.gov, number NCT03353753, and with WHO International Clinical Trials Registry Platform, number EUCTR2017-002446-76-ES; follow-up is ongoing. Findings: Between Feb 27, 2018, and Nov 16, 2018, 129 of 154 assessed patients were randomly assigned to receive either Ripretinib (n=85) or placebo (n=44). At data cutoff (May 31, 2019), at a median follow-up of 6·3 months (IQR 3·2-8·2) in the Ripretinib group and 1·6 months (1·1-2·7) in the placebo group, 51 patients in the Ripretinib group and 37 in the placebo group had had progression-free survival events. In the double-blind period, median progression-free survival was 6·3 months (95% CI 4·6-6·9) with Ripretinib compared with 1·0 months (0·9-1·7) with placebo (hazard ratio 0·15, 95% CI 0·09-0·25; p<0·0001). The most common (>2%) grade 3 or 4 treatment-related treatment-emergent adverse events in the Ripretinib group (n=85) included lipase increase (four [5%]), hypertension (three [4%]), fatigue (two [2%]), and hypophosphataemia (two (2%]); in the placebo group (n=43), the most common (>2%) grade 3 or 4 treatment-related treatment-emergent adverse events were anaemia (three [7%]), fatigue (one [2%]), diarrhoea (one [2%]), decreased appetite (one [2%]), dehydration (one [2%]), hyperkalaemia (one [2%]), acute kidney injury (one [2%]), and pulmonary oedema (one [2%]). Treatment-related serious adverse events were reported in eight (9%) of 85 patients who received Ripretinib and three (7%) of 43 patients who received placebo. Treatment-related deaths occurred in one patient in the placebo group (septic shock and pulmonary oedema) and one patient in the Ripretinib group (cause of death unknown; the patient died during sleep). Interpretation: Ripretinib significantly improved median progression-free survival compared with placebo and had an acceptable safety profile in patients with advanced gastrointestinal stromal tumours who were resistant to approved treatments.

Ripretinib in gastrointestinal stromal tumor: the long-awaited step forward
Ther Adv Med Oncol 2021 Jan 7;13:1758835920986498.PMID:33473249DOI:10.1177/1758835920986498.
Gastrointestinal stromal tumor (GIST) represents a paradigm for clinically effective targeted inhibition of oncogenic driver mutations in cancer. Five drugs are currently positioned as the standard of care for the treatment of advanced or metastatic GIST patients. This is the result of continuous, deep understanding of KIT and PDGFRA GIST oncogenic drivers as well as the resistance mechanisms associated to tumor progression. However, the complexity of GIST molecular heterogeneity is an evolving field, and critical questions remain open. Specifically, the clinical benefit of approved and/or investigated targeted agents is strikingly modest at advanced stages of the disease when compared with the activity of first-line imatinib. Ripretinib is a novel switch-pocket inhibitor with broad activity against KIT and PDGFRA oncoproteins and has recently demonstrated antitumoral activity across phase I to phase III clinical trials. Therefore, Ripretinib has emerged as a new standard of care for advanced, multi-resistant GIST patients. Based on this data, the Food and Drug Administration has granted in 2020 the approval of Ripretinib for GIST patients after progression to imatinib, sunitinib and regorafenib. This, in turn, constitutes a major breakthrough in sarcoma drug development, as there have not been new treatment approvals in GIST for nearly a decade. Herein, we provide a critical review on the preclinical and clinical development of Ripretinib in GIST. Furthermore, we seek to assess the biological and clinical impact of this new standard of care on the course of the disease, aiming to provide an insight on future treatments strategies for the next coming years.
Ripretinib for the treatment of advanced gastrointestinal stromal tumor
Therap Adv Gastroenterol 2021 Apr 15;14:17562848211008177.PMID:33948116DOI:10.1177/17562848211008177.
Gastrointestinal stromal tumors (GISTs) are rare tumors of the gastrointestinal (GI) tract yet represent the most common GI sarcomas. Most GISTs are driven by activating mutations of the KIT and/or PDGFRA genes. Prior to the development of tyrosine kinase inhibitors (TKIs), GISTs were associated with a poor prognosis because conventional cytotoxic chemotherapy was relatively ineffective. However, TKIs that inhibit the most common driver mutations in KIT or PDGFRA have revolutionized the treatment of GISTs over the past two decades. Notwithstanding, ongoing management challenges relate to the development of secondary mutations in these genes, resulting in tumor progression. Due to both the intra- and inter-patient heterogeneity of these secondary mutations in GISTs, optimal treatment requires an agent that blocks as many mutant genes as possible. Ripretinib - a novel switch-control TKI - inhibits many of the most common primary and secondary activating KIT and PDGFRA mutants involved in GIST progression through a dual mechanism of action. In the pivotal INVICTUS phase III trial, patients with advanced GIST that had progressed on at least imatinib, sunitinib, and regorafenib and who received Ripretinib experienced significantly longer progression-free survival (primary endpoint) as well as prolongation of overall survival, compared with those receiving placebo. Treatment with Ripretinib was associated with durable improvements in quality-of-life indices and a manageable toxicity profile. The most frequent side effects were common to the class of TKIs used in the management of GIST. These results led to the approval of Ripretinib for treatment of advanced GIST in adults who have received three or more TKIs, including imatinib. Ripretinib is also under investigation in the second-line treatment of advanced GIST in a phase III trial (INTRIGUE) comparing Ripretinib with sunitinib in patients with advanced GIST after treatment with imatinib. Plain language summary: Use of Ripretinib for the treatment of gastrointestinal stromal tumors (GISTs) Gastrointestinal stromal tumors (GISTs) are a rare type of tumor most commonly located in the stomach and small intestine but can develop anywhere throughout the gastrointestinal tract. The symptoms of GISTs vary in extent depending on location of the primary tumor and include a feeling of fullness, abdominal pain, intestinal bleeding, and fatigue. Since these symptoms are nonspecific, making a diagnosis can be challenging. Most GISTs carry initial mutations in genes that control specific enzymes called tyrosine kinases. Historically, treatment of GISTs was limited because traditional chemotherapy is ineffective against these tumors. However, with the introduction of drugs that inhibit tyrosine kinases [i.e., tyrosine kinase inhibitors (TKIs)], survival has been extended substantially. However, many GISTs go on to develop secondary mutations that render them resistant to a given TKI. Prior to the approval of Ripretinib, four TKIs were available for the treatment of GIST: imatinib; sunitinib; regorafenib; and, recently, avapritinib. Each drug is used until resistance develops or patients are unable to tolerate the side effects of treatment, after which the next drug is started. Ripretinib was recently approved by the FDA as the fourth drug in the usual treatment sequence recommended for patients with advanced GIST who have progressed (or are treatment intolerant) after receiving three or more TKIs, including imatinib. Approval of Ripretinib was based on the results of the INVICTUS trial, which demonstrated that the drug significantly improves the time patients have without progression of the disease or death compared with placebo. The most common side effects related to Ripretinib were hair loss, muscle pain, nausea, fatigue, hand-foot syndrome, and diarrhea, although most events were not very severe. Ripretinib is being further studied as the second TKI used in patients with GIST who have progressed on or could not tolerate first-line treatment with imatinib.
