Enhancement of Soft Tissue Sarcoma Response to Gemcitabine through Timed Administration of a Short-Acting Anti-Angiogenic Agent.
    Cellular physiology and biochemistry : international journal of experimental cellular physiology, biochemistry, and pharmacology, 2020, Jul-29, Volume: 54, Issue:4

    Despite enormous effort, anti-angiogenic drugs have not lived up to the promise of globally-enhancing anti-cancer therapies. Clinically, anti-angiogenic drugs have been used to persistently suppress vascular endothelial growth factor (VEGF) in order to "normalize" dysfunctional neo-angiogenic microvasculature and prevent recruitment of endothelial progenitors. Recently, we showed that a 1h pre-treatment with anti-angiogenic drugs prior to ultra-high single dose radiotherapy and specific chemotherapies transiently de-represses acid sphingomyelinase (ASMase), leading to enhanced cancer therapy-induced, ceramide-mediated vascular injury and tumor response. Here we formally decipher parameters of chemotherapy induction of endothelial sphingolipid signaling events and define principles for optimizing anti-angiogenic chemosensitization.. These studies examine the antimetabolite chemotherapeutic gemcitabine in soft tissue sarcoma (STS), a clinically-relevant combination.. Initial studies address the theoretic problem that anti-angiogenic drugs such as bevacizumab, an IgG with a 3-week half-life, have the potential for accumulating during the 3-week chemotherapeutic cycles currently standard-of-care for STS treatment. We show that anti-angiogenic ASMase-dependent enhancement of the response of MCA/129 fibrosarcomas in sv129/BL6 mice to gemcitabine progressively diminishes as the level of the VEGFR2 inhibitor DC101, an IgG, accumulates, suggesting a short-acting anti-angiogenic drug might be preferable in multi-cycle chemotherapeutic regimens. Further, we show lenvatinib, a VEGFR2 tyrosine kinase inhibitor with a short half-life, to be superior to DC101, enhancing gemcitabine-induced endothelial cell apoptosis and tumor response in a multi-cycle treatment schedule.. We posit that a single delivery of a short-acting anti-angiogenic agent at 1h preceding each dose of gemcitabine and other chemotherapies may be more efficacious for repeated sensitization of the ASMase pathway in multi-cycle chemotherapy regimens than current treatment strategies.

Antitumour activity of oral E7080, a novel inhibitor of multiple tyrosine kinases, in human sarcoma xenografts.
    International journal of cancer, 2011, Aug-01, Volume: 129, Issue:3

    E7080 is an inhibitor of multiple tyrosine kinases, several of which have pro-angiogenic properties, including receptors for VEGF, FGF, SCF and PDGF. We undertook our study to evaluate the preclinical activity of E7080 in human sarcomas. The antitumour activity of orally administered E7080 was tested in ten human tumour xenografts representing different sarcoma histotypes. Concomitant changes in microvessel density were assayed by immunohistochemistry to CD31. Immunohistochemistry was also used to assess the expression of kinases that E7080 is known to inhibit. The MTS assay was applied to determine effects on tumour cell viability in vitro. At the Q1D5 × 2 schedule, E7080 (30 mg/kg) was active (T/C<40%) in 7/10 xenografts. The effects were accompanied by marked decrease in microvessel densities. Given at the Q1D5 × 4 schedule, E7080 (30, 10, 3 mg/kg) showed antitumour activity in a dose dependent manner in two different xenografts. E7080 growth inhibition did not correlate with the expression of VEGFR1-3, PDGFRA, PDGFRB, FGFR1 or KIT on tumour cells but was significantly correlated with expression of VEGFR2 on tumour microvessels. In vitro E7080 did not show potent effects on tumour cell viability in four different sarcoma cell lines, with IC50 values ≥ 10 μM. In conclusion, E7080 showed broad in vivo antitumour activity in sarcoma, mainly attributable to angiogenesis inhibition. E7080 was also active in xenografts resistant to one or more clinically relevant reference drugs given at MTD (doxorubicin, cisplatin or ifosfamide). The present results encourage further investigation of a potential role of E7080 in sarcoma therapy in the clinic.
