Clinical, P1/2 data, PK/PD data, Journal, Combination therapy: Pharmacodynamic and clinical results from a phase 1/2 study of the HSP90 inhibitor onalespib in combination with abiraterone acetate in prostate cancer. (Pubmed Central) - Sep 17, 2020 HSP72 was significantly up-regulated following onalespib treatment, but only a modest decrease in AR and GR was shown in paired pre- and post-treatment tumor biopsy samples. No subjects showed an objective or PSA response Onalespib in combination with AA/P, showed mild evidence of some biological effect, however this effect did not translate into clinical activity, hence further exploration of this combination was not justified.

Journal: The HSP90 inhibitor onalespib potentiates 177Lu‑DOTATATE therapy in neuroendocrine tumor cells. (Pubmed Central) - Apr 3, 2020 Consequently, the combination of onalespib and 177Lu‑DOTATATE may prove to be a promising strategy with which to improve therapeutic responses in patients with NETs. Further studies investigating this strategy in vivo regarding the therapeutic effects and potential toxicities are warranted to expand these promising findings.

Journal: HSP90 inhibitors diminish PDGF-BB-induced migration of osteoblasts via suppression of p44/p42 MAP kinase. (Pubmed Central) - Jan 12, 2020 Onalespib, an HSP90 inhibitor, significantly reduced the PDGF-BB-stimulated migration evaluated by the two types of migration assays...In addition, the phosphorylation of p44/p42 MAP kinase by PDGF-BB was reduced by geldanamycin. Taken together, these results strongly suggest that HSP90 inhibitors suppress the PDGF-BB-induced osteoblast migration through the attenuation of p44/p42 MAP kinase activity.

- |||||||||| Increasing extent of ablation - a senolytic approach to promote apoptosis of latent glioblastoma following chemoradiation. (Ballroom Lawn) - Oct 29, 2019 - Abstract #SNO2019SNO_1272;
Current therapies, including radiation and temozolomide, are known to induce senescence in tumor cells...Given existence of multiple SCAPs, we evaluated the IC50 for several senolytic candidates including Dasatinib, Quercetin, Fisetin, AMG-232, Onalespib, A1331852, and Navitoclax in radiated vs non-radiated cells... Our findings suggest that blocking the anti-apoptotic pathway Bcl-XL in GBM cells rendered at least transiently senescent following radiation may provide an avenue to selectively ablate residual glioblastoma cells following radiation. Our data provide proof of principle that senolytic therapy may represent a previously untapped window of opportunity to increase extent of tumor ablation following completion of standard cytotoxic therapies.

- |||||||||| Journal: Proteomic analysis of proteome and histone post-translational modifications in heat shock protein 90 inhibition-mediated bladder cancer therapeutics. (Pubmed Central) - Sep 7, 2018
Furthermore, quantitative proteome studies identified 14 types of PTMs with 93 marks on the core histones, including 34 novel histone marks of butyrylation, citrullination, 2-hydroxyisobutyrylation, methylation, O-GlcNAcylation, propionylation, and succinylation in AUY922- and ganetespib-treated 5637 cells. Together, this study outlines the association between proteomic changes and histone PTMs in response to HSP90 inhibitor treatment in bladder carcinoma cells, and thus intensifies the understanding of HSP90 inhibition-mediated bladder cancer therapeutics.
