  • AYVAKIT (Avapritinib) RATIONALE for INCLUSION in PA PROGRAM
    AYVAKIT (avapritinib) RATIONALE FOR INCLUSION IN PA PROGRAM Background Ayvakit (avapritinib) is a tyrosine kinase inhibitor that targets platelet-derived growth factor receptor alpha (PDGFRA) and PDGFRA D842 mutants as well as multiple KIT exon 11, 11/17 and 17 mutants. Certain mutations in PDGFRA and KIT can result in the autophosphorylation and constitutive activation of these receptors which can contribute to tumor cell proliferation. Other potential targets for Ayvakit include wild type KIT, PDGFRB, and CSFR1. Ayvakit inhibits the autophosphorylation of KIT D816V and PDGFRA D842V, mutants associated with resistance to approved kinase inhibitors. This could contribute to its inhibition of tumor cell proliferation (1). Regulatory Status FDA-approved indications: Ayvakit is a kinase inhibitor indicated for: (1) • Gastrointestinal Stromal Tumor (GIST) o the treatment of adults with unresectable or metastatic GIST harboring a platelet- derived growth factor receptor alpha (PDGFRA) exon 18 mutation, including PDGFRA D842V mutations • Advanced Systemic Mastocyosis (AdvSM) o the treatment of adult patients with AdvSM. AdvSM includes patients with aggressive systemic mastocytosis (ASM), systemic mastocytosis with an associated hematological neoplasm (SM-AHN), and mast cell leukemia (MCL). o Limitations of Use: Ayvakit is not recommended for the treatment of patients with AdvSM with platelet counts of less than 50 x 109/L Ayvakit has warnings regarding intracranial hemorrhage, cognitive effects and embryo-fetal toxicity. Serious intracranial hemorrhage may occur in patients treated with Ayvakit. Ayvakit should be discontinued if intracranial hemorrhage of any grade occurs. A broad spectrum of cognitive adverse reactions can occur in patients receiving Ayvakit. Ayvakit can cause fetal harm when administered to pregnant women.

  • Tyrosine Kinase Inhibitors for Solid Tumors in the Past 20 Years (2001–2020) Liling Huang†, Shiyu Jiang† and Yuankai Shi*
    Huang et al. J Hematol Oncol (2020) 13:143 https://doi.org/10.1186/s13045-020-00977-0 REVIEW Open Access Tyrosine kinase inhibitors for solid tumors in the past 20 years (2001–2020) Liling Huang†, Shiyu Jiang† and Yuankai Shi* Abstract Tyrosine kinases are implicated in tumorigenesis and progression, and have emerged as major targets for drug discovery. Tyrosine kinase inhibitors (TKIs) inhibit corresponding kinases from phosphorylating tyrosine residues of their substrates and then block the activation of downstream signaling pathways. Over the past 20 years, multiple robust and well-tolerated TKIs with single or multiple targets including EGFR, ALK, ROS1, HER2, NTRK, VEGFR, RET, MET, MEK, FGFR, PDGFR, and KIT have been developed, contributing to the realization of precision cancer medicine based on individual patient’s genetic alteration features. TKIs have dramatically improved patients’ survival and quality of life, and shifted treatment paradigm of various solid tumors. In this article, we summarized the developing history of TKIs for treatment of solid tumors, aiming to provide up-to-date evidence for clinical decision-making and insight for future studies.

This article is published with open access Abstract Advanced systemic mastocytosis (advSM) is characterized by the presence of an acquired KIT D816V mutation in >90% of patients. In the majority of patients, KIT D816V is not only detected in mast cells but also in other hematopoietic lineages. We sought to investigate the effects of the KIT-inhibitors midostaurin and avapritinib on single-cell-derived myeloid progenitor cells using granulocyte-macrophage colony-forming-units of patients with KIT D816V positive advSM. Colonies 1234567890();,: 1234567890();,: obtained prior to treatment were incubated in vitro with midostaurin (n = 10) or avapritinib (n = 11) and showed a marked reduction (≥50%) of KIT D816V positive colonies in 3/10 (30%) and 7/11 (64%) patient samples, respectively. Three of those 7 (43%) avapritinib responders were resistant to midostaurin in both, in vitro and in vivo. Colonies from four patients with high-risk molecular profile and aggressive clinical course were resistant to both drugs. The in vitro activity of midostaurin strongly correlated with clinical and molecular responses, e.g., relative reduction of KIT D816V allele burden and the proportion of KIT D816V positive colonies obtained after six months midostaurin-treatment in vivo.

This article is part of the Topical Collection on Sarcoma Keywords Gastrointestinal stromal tumour I GIST I Tyrosine kinase inhibitors I TKI I Avapritinib I Ripretinib Opinion statement The treatment of advanced GIST is rapidly evolving with the development of novel molecular compounds such as avapritinib and ripretinib, but also promising results have been achieved with cabozantinib in a phase II trial. The availability of over five lines of treatment for patients with advanced GIST is likely to completely shift the current second-line and third-line treatment options, and will also potentially enable a personalised approach to treatment. Imatinib will most likely remain as the first-line treatment of choice for the vast majority of GIST patients. However, for GIST patients with tumours harbouring a D842V mutation in PDGFRA exon 18, avapritinib has shown efficacy and will become first-line therapy for this molecular subgroup.
