SYDNEY, June 13, 2022 /PRNewswire/ -- Kazia Therapeutics Limited (NASDAQ: KZIA; ASX: KZA), an oncology-focused drug development company, is pleased to announce the presentation of new data regarding the activity of paxalisib in two forms of childhood brain cancer with poor prognosis and limited treatment options.
The data is the subject of two poster presentations at the 20th International Symposium on Pediatric Neuro-Oncology (ISPNO), held in Hamburg, Germany, from 12-15 June 2022.
The first poster is presented by Dr Jeffrey Rubens at Johns Hopkins University and describes the activity of paxalisib in combination with a second drug in animal models of atypical teratoid / rhabdoid tumors (AT/RT). This builds on work previously presented at the American Association of Cancer Research (AACR) Annual Meeting in April 2022.
The second poster presents work led by Associate Professor Matt Dun at the Hunter Medical Research Institute at the University of Newcastle, Australia, and involving collaboration by ten international laboratories and leading paediatric cancer centres. The research principally relates to the combination of paxalisib with ONC201, an investigational therapy manufactured by Chimerix, Inc, in the treatment of diffuse intrinsic pontine glioma (DIPG). While the primary focus of the ISPNO presentation concerns animal models of the disease, two clinical case studies are also reported. Importantly, these data underpin the ongoing phase II clinical trial testing the safety and efficacy of paxalisib and ONC201 in DIPG.
Upcoming Webinar
Lead investigator on the DIPG research, Dr Matt Dun, will participate in an investor webinar alongside Kazia CEO, Dr James Garner, and Kazia Chief Medical Officer, Dr John Friend, to discuss the new ISPNO data and the broader context of Kazia's work in childhood brain cancer. The webinar is scheduled for 5pm, ET, on Wednesday, June 22nd (7am, Sydney time on Thursday, 23rd June), and interested parties may register via the following link:
Key Points
"Brain tumours are the second most common cancer of children, but the leading cause of death, with the prognosis for aggressive forms of the disease such as DIPG remaining woeful," said Dr Matt Dun, lead investigator of the DIPG research. "It is vital that we find new treatments. This research collaboration has united many of the leading international centres in this field and has deployed cutting edge research tools to identify an extremely promising combination of therapies. My colleagues and I hope to see these laboratory findings validated in the ongoing PNOC clinical trial, which may establish ONC201 and paxalisib as the cornerstones of treatment for children and their families affected by this disease."
Kazia CEO, Dr James Garner, added, "Dr Dun's painstaking research over several years has yielded enormous insight into potential treatments for DIPG. We are excited to see such an emphatic demonstration of the potential for ONC201 and paxalisib to provide benefit in this disease. We are firmly committed to taking paxalisib forward in childhood brain cancer, and very much hope that the work of world-leading scientists such as Dr Dun will help to bring hope to all those touched by diseases such as DIPG."

About Kazia Therapeutics Limited
Kazia Therapeutics Limited (NASDAQ: KZIA; ASX: KZA) is an oncology-focused drug development company, based in Sydney, Australia.
Our lead program is paxalisib, a brain-penetrant inhibitor of the PI3K / Akt / mTOR pathway, which is being developed to treat glioblastoma, the most common and most aggressive form of primary brain cancer in adults. Licensed from Genentech in late 2016, paxalisib commenced recruitment to GBM AGILE, a pivotal study in glioblastoma, in January 2021. Seven additional studies are active in various forms of brain cancer. Paxalisib was granted Orphan Drug Designation for glioblastoma by the US FDA in February 2018, and Fast Track Designation for glioblastoma by the US FDA in August 2020. In addition, paxalisib was granted Rare Pediatric Disease Designation and Orphan Designation by the US FDA for DIPG in August 2020.
Kazia is also developing EVT801, a small-molecule inhibitor of VEGFR3, which was licensed from Evotec SE in April 2021. Preclinical data has shown EVT801 to be active against a broad range of tumour types and has provided compelling evidence of synergy with immuno-oncology agents. A phase I study commenced recruitment in November 2021.
