Definitions

• Abelson-family tyrosine kinases are host targets that can be inhibited by small molecules (ATKis) to create anti-cancer and anti-infective therapeutics.
• ATKis small molecules
• ATKis small molecules
• ATKs are co-opted by a pathogen to enter, reproduce or exit host cells, accounting for the antimicrobial effects of ATKis. Because the targets of these therapeutics to treat infectious disease overlap with the targets for certain types of cancer, the same medications for infectious disease can be applied to treat cancer at the same dose.
• PML Progressive Multifocal Leukoencephalopathy
• brain-infective form of the virus is not acquired by transmission from an infected patient. Instead, brain-infective JCV is formed by genomic rearrangement of the nonpathogenic form of the virus that resides outside of the brain in a persistently infective state within a patient. This non-pathogenic, or archetype JCV, which is detected in the kidney, genitourinary tract and bone marrow, is kept in check by the host cellular immune response. The transformation to the brain-infective form occurs when a patient undergoes a sustained disruption of cellular immunity, which could be caused by either immune-suppressing drugs to treat autoimmune disease (e.g. MS) or by development of clinical AIDS following HIV infection.
• immune-suppressing drugs to treat autoimmune disease (e.g. MS) or by development of clinical AIDS following HIV infection.
• NCCR non-coding control region
• VP1 viral capsid protein
• Lytic infection of JCV in the brain causes irreversible damage to neural tissue.
• Chronic Myeloid Leukemia is a myeloproliferative neoplasm with an incidence of 1-2 cases per 100,000 persons, and accounts for -15% of newly diagnosed cases of leukemia in adults.
• Pathogenesis of CML is linked to the fusion of the Abel son murine leukemia (ABL) gene on chromosome 9 with the breakpoint cluster region (BCR) gene on chromosome 22, resulting in expression of fusion protein, termed BCR- ABL
• BCR-ABL is a constitutively active tyrosine kinase that promotes growth and replication through downstream pathways such as RAS, RAF, JUN kinase, MYC, and STAT.
• BCR-ABL expression creates a cytokine-independent cell cycle with aberrant apoptotic signals in response to cytokine withdrawal.
• ATK small molecule ATKis that potently interfere with the interaction between BCR-ABL and ATP were shown to block cellular proliferation of the malignant clone.
• This "targeted" approach was found to dramatically alter the natural history of the disease, improving 10-year overall survival (OS) from -20% to >80%.
• Three such targeted therapies have been approved for first line treatment of CML: imatinib (Gleevec®), nilotinib (Tasigna®) and dasatinib (Sprycel®).
• Gleevec as a chronic medication. Treatment failures were often linked to the development of Gleevec resistance arising from secondary mutations in the Abl-kinase domain of the fusion protein, resulting in a loss of Gleevec potency and relapse of disease.
• Sprycel a dual Abl- and SRC-kinase inhibitor, was the second approved agent and a much more potent inhibitor of BCR-ABL. Sprycel induces more rapid responses and suppression of fusion protein expression at much earlier timepoints than Gleevec. But, as a SRC inhibitor, significant side effects counterbalanced the value of the enhanced response profile that Sprycel displayed.
• Tasigna was developed to directly address Gleevec resistance, and, early in its development, demonstrated potent inhibitory activity against many clinically relevant BCR-ABL mutants that no longer responded to Gleevec therapy (Table 3). Like Sprycel, Tasigna was as much as 20x more potent as an inhibitor of BCR-ABL relative to Gleevec (Table 3). However, Tasigna' s potency was accompanied by a side effect profile with severe adverse event frequency similar to Spry eel, limiting its utility as a chronic medication.
• Spry eel Patients at risk of developing pleural effusions, for example, such as patients with a history of lung disease (e.g., COPD), cardiac disease (e.g., congestive heart failure or pulmonary arterial hypertension) or patients with uncontrolled hypertension, make Spry eel a poor choice. Sprycel also inhibits platelet function, so patients taking anticoagulants could be at risk for bleeding complications while on Sprycel. Tasigna is associated with
• Tasigna may also prolong the QT interval and therefore may be contraindicated in patients with cardiac complications, although longer-term follow-up studies appear to be needed to confirm this observation.
• the non-linear accumulation of Tasigna that occurs when taken in the context of a fatty diet also places patients at risk for reaching severe dose-limiting toxicities, requiring fasting before and after dosing with Tasigna for 2 hours; as Tasigna is given 2x/day, this means patients on Tasigna are fasting as much as 8 hours out of every 24.
• GIST Gastrointestinal Stromal Tumors
• mesenchymal tumors originating in the digestive tract have a characteristic morphology and are generally positive for CD117 (c-kit) and are primarily caused by activating mutations in the KIT or PDGFRa, both protein kinases in the Abelson-kinase family which are susceptible to treatment with ATKis.
• KIT and/or PDGFRa associated GIST treated with frontline TKIs like imatinib can eventually develop resistance to therapy through the formation of secondary mutations in either KIT or PDGFRa; imatinib also displays poor response rates in KIT exon 9 and wildtype associated tumors, both of which are more responsive to higher affinity ATKis like sunitinib and regorafenib.
