Atossa Therapeutics and Insilico Medicine Publish Study on (Z)-Endoxifen for Glioblastoma
Atossa Therapeutics, Inc. (Nasdaq: ATOS), a clinical-stage biopharmaceutical company, has partnered with Insilico Medicine, a leader in AI-powered drug discovery, to publish a study investigating the therapeutic potential of (Z)-endoxifen for glioblastoma multiforme (GBM). This comprehensive research, recently featured in Nature Scientific Reports, aims to explore new oncology indications for endoxifen, potentially one of the most promising candidates for treating one of the most aggressive forms of brain cancer.
Study Findings on (Z)-Endoxifen
(Z)-Endoxifen is an active metabolite of tamoxifen, which has shown activity in endocrine-resistant breast cancer. The study utilized Insilico's AI-powered PandaOmics platform to evaluate over 900 cancer indications and identify GBM as a significant candidate for treatment exploration. The results reveal critical insights into the workings of endoxifen as a therapeutic option for GBM.
Significance of the Research
The publication sheds light on GBM, known for its extremely low five-year survival rate of approximately 4%. By employing various AI-enabled methodologies, including transcriptomic integration and computational modeling, the study provides a foundational understanding of how (Z)-endoxifen could disrupt the biological processes contributing to tumor growth and resistance. Key findings include:
- Identification of over 1,400 genes shared between GBM tumors and endoxifen-treated cells.
- Reversal of biological programs driving uncontrolled tumor proliferation and aggressive behavior.
- Significant suppression of GBM cell proliferation in laboratory tests, surpassing the effectiveness of traditional treatments like temozolomide.
Collaboration Highlights
Steven Quay, M.D., Ph.D., CEO of Atossa Therapeutics, emphasized the importance of this collaboration, stating, "This collaboration with Insilico Medicine provides a whole new indication in which we might explore the utility of endoxifen, addressing an extremely underserved set of cancer patients." Dr. Quay noted that while the focus has primarily been on women's health, this research marks a significant expansion into glioblastoma exploration.
Future Implications and Laboratory Validation
The laboratory findings closely aligned with the study's computational predictions. In vitro results demonstrated that (Z)-endoxifen induced apoptosis and exhibited greater cytotoxicity than high-dose temozolomide. Moreover, in vivo studies confirmed the tolerability of endoxifen across various doses, solidifying its potential as a therapeutic candidate for GBM.
