Kazia Therapeutics Limited Directors’ report 31 December 2020 | |  |
Paxalisib has completed a 47-patient phase I clinical study under Genentech in patients with progressive or recurrent high grade glioma (NCT01547546), which showed the drug to be generally safe and well-tolerated, and which provided pharmacodynamic proof of concept and signals of potential clinical activity. This study was published in Clinical Cancer Research, and a companion paper detailing a post hoc analysis of imaging data from the study has been published in the same journal.
In February 2020, the company completed recruitment to a phase II clinical trial of paxalisib in patients with newly-diagnosed glioblastoma and unmethylated MGMT promotor status (NCT03522298), which is the primary target commercial population. This study has reported several interim data read-outs during CY2020, showing a strong signal of potential clinical activity. The study remains ongoing in follow-up, and final data is anticipated during CY2021.
In October 2020, the company executed a definitive agreement with the Global Coalition for Adaptive Research (GCAR) to introduce paxalisib into the ongoing adaptive platform study, GBM AGILE (NCT03970447). This study is designed to provide substantial evidence for approval of new drugs in glioblastoma, and is intended to serve as the pivotal study for paxalisib in US, EU, China, and other markets. The first patient recruited by a site opened to the paxalisib arm occurred on 7 January 2021.
Four investigator-initiated studies continued to progress during the period: a phase I study with paxalisib in diffuse intrinsic pontine glioma (DIPG) at St Jude Children’s Research Hospital in Memphis, TN (NCT03696355), a phase II study with paxalisib in HER2+ breast cancer brain metastases at Dana-Farber Cancer Institute in Boston, MA (NCT03765983), a phase II multi-drug, genomically-guided study in brain metastases run by the Alliance for Clinical Trials in Oncology (NCT03994796), and a phase I study with paxalisib in combination with radiotherapy for brain metastases at Memorial Sloan Kettering Cancer Center in New York, NY (NCT04192981).
In September 2020, the company entered into an agreement with Dana-Farber Cancer Institute in Boston, MA to launch a new investigator-initiated study in primary CNS lymphoma. This study is expected to commence recruitment during 1H CY2021.
The consolidated entity is also developing Cantrixil (TRX-E-002-1), a small-molecule agent arising from an in-house discovery program. Through a collaboration with researchers at Yale University, Cantrixil has shown in vitro and in vivo activity against both differentiated cancer cells and cancer stem cells (sometimes referred to as tumour-initiating cells), which are believed to be an important contributor to chemotherapy resistance and disease recurrence. A phase I study of Cantrixil in patients with advanced recurrent epithelial ovarian cancer (NCT02903771) has been completed, and top-line data was announced in December 2020. The company expects a full study publication during 1H CY2021.
