    Activating GCN2 and subsequently the Unfolded Protein Response with the small oral molecule NXP800 delays tumor growth in osteosarcoma. (PubMed, Cell Death Discov)
    Finally, NXP800 delays tumor growth in preclinical OS model by promoting apoptosis. This study is a preclinical proof-of-principle of therapeutic efficacy of NXP800 both in vitro and in vivo, highlighting the relevance of targeting GCN2, and consequently activating the ISR and UPR, to induce apoptosis and inhibit tumor progression in OS.

    Advances in Prostate Cancer Treatment: Exploring Molecular Targets and New Strategies in Castration-Resistant Disease. (PubMed, Cureus)
    Key developments include next-generation AR pathway inhibitors, such as darolutamide, with improved safety profiles; PARP inhibitors for patients with DNA repair gene mutations; and PSMA-targeted radioligand therapy. The therapeutic landscape is also expanding to include novel targets such as the heat shock response, with HSF1 inhibitors like NXP800 in clinical trials for treatment-refractory disease. By targeting this molecular heterogeneity, ongoing research aims to deliver more effective, personalized treatments to improve survival and quality of life for men with advanced prostate cancer.

    NXP800 activates the unfolded protein response, altering AR and E2F function to impact castration-resistant prostate cancer growth. (PubMed, Clin Cancer Res)
    Overall, NXP800 has anti-tumor activity against treatment-resistant PCa models, including molecular subtypes with limited treatment options, supporting its consideration for PCa-specific clinical development.

    HSF1 Pathway Inhibitor Clinical Candidate (CCT361814/NXP800) Developed from a Phenotypic Screen as a Potential Treatment for Refractory Ovarian Cancer and Other Malignancies. (PubMed, J Med Chem)
    Further multiparameter optimization led to the design of the clinical candidate, CCT361814/NXP800 22, a potent and orally bioavailable fluorobisamide, which caused tumor regression in a human ovarian adenocarcinoma xenograft model with on-pathway biomarker modulation and a clean in vitro safety profile. Following its favorable dose prediction to human, 22 has now progressed to phase 1 clinical trial as a potential future treatment for refractory ovarian cancer and other malignancies.
