Company and FDA to meet in December to discuss potential pathways to registration of paxalisib in glioblastoma multiforme (GBM)

Company updates to corporate presentation and participation in upcoming medical meetings

SYDNEY, Nov. 4, 2024 /PRNewswire/ -- Kazia Therapeutics Limited (NASDAQ: KZIA), an oncology-focused drug development company, announced that the U.S. Food and Drug Administration (FDA) has granted a Type C meeting with the Company in December 2024 to discuss the potential pathways to registration of Kazia's blood brain barrier penetrant PI3K/mTOR inhibitor, paxalisib, for the treatment of patients with newly diagnosed GBM.

In July 2024, the Company announced results from the Phase II/III clinical trial, GBM-AGILE, in which newly diagnosed unmethylated patients with glioblastoma treated with paxalisib showed clinically meaningful improvement in a prespecified secondary analysis for overall survival. Full data including secondary endpoints from the paxalisib arm of the GBM-AGILE study is expected to be presented at a scientific meeting later this year.

Paxalisib has previously received orphan drug designation and fast track designation from the FDA for glioblastoma in unmethylated MGMT promoter status patients, following radiation plus temozolomide therapy. 

Updated corporate presentation
Today, the Company also announced that it has updated its corporate presentation, which now incorporates preliminary data from the GBM AGILE Phase II/III clinical trial evaluating paxalisib versus the standard of care for the treatment of in patients with glioblastoma.

About Kazia Therapeutics Limited

Kazia Therapeutics Limited (NASDAQ: KZIA) is an oncology-focused drug development company, based in Sydney, Australia. Our lead program is paxalisib, an investigational brain-penetrant inhibitor of the PI3K / Akt / mTOR pathway, which is being developed to treat multiple forms of brain cancer. Licensed from Genentech in late 2016, paxalisib is or has been the subject of ten clinical trials in this disease. A completed Phase 2 study in glioblastoma reported early signals of clinical activity in 2021, and a pivotal study in glioblastoma, GBM AGILE, has been completed with presentation of paxalisib arm data expected later in 2024 at a major medical conference. Other clinical trials involving paxalisib are ongoing in brain metastases, diffuse midline gliomas, and primary CNS lymphoma, with several of these trials having reported encouraging interim data. Paxalisib was granted Orphan Drug Designation for glioblastoma by the FDA in February 2018, and Fast Track Designation (FTD) for glioblastoma by the FDA in August 2020. Paxalisib was also granted FTD in July 2023 for the treatment of solid tumour brain metastases harboring PI3K pathway mutations in combination with radiation therapy. In addition, paxalisib was granted Rare Pediatric Disease Designation and Orphan Drug Designation by the FDA for diffuse intrinsic pontine glioma in August 2020, and for atypical teratoid / rhabdoid tumours in June 2022 and July 2022, respectively. 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 evidence of synergy with immuno-oncology agents. A Phase I study has been completed and preliminary data was presented at 15th Biennial Ovarian Cancer Research Symposium in September 2024.
