SYDNEY, Australia I March 28, 2018 I Kazia Therapeutics Limited (ASX: KZA; NASDAQ: KZIA), an Australian oncology drug development company, is pleased to announce commencement of an international phase II clinical trial of its lead program, GDC-0084.

Key Points

  • First site, Stephenson Cancer Center at the University of Oklahoma, has been initiated and will begin screening patients after the Easter holidays
  • Study commencement follows a successful meeting with US Food & Drug Administration (FDA) in September 2017, and approval by Western Institutional Review Board in November 2017
  • Initial focus will be on dose optimization in the treatment of newly-diagnosed patients with glioblastoma multiforme; adaptive study design will then seek to provide definitive evidence of clinical efficacy

GDC-0084 is being developed for glioblastoma multiforme (GBM), the most common and most aggressive form of primary brain cancer. The mainstay of current pharmacological treatment, temozolomide, is effective only in about one third of patients, and median survival is approximately 12 to 15 months from diagnosis.

Kazia licensed GDC-0084 in late 2016 from Genentech, a member of the Roche Group, where it had previously completed a phase I clinical study in 47 patients with advanced glioma. Genentech’s phase I study demonstrated a favourable safety profile and provided signals of efficacy. Genentech also conducted an extensive preclinical program which showed encouraging results for GDC-0084 in animal models of glioblastoma.

Kazia CEO, Dr James Garner, commented, “the entire team has been working hard to design and implement the GDC-0084 clinical study. We are very pleased to now have the trial underway, and look forward to working with the participating clinicians. The need for new therapies in this disease remains immense, and we believe that GDC-0084 may have a valuable role to play in improving outcomes for patients with glioblastoma.”

This phase II study will initially be conducted predominantly at leading US-based centres, in collaboration with specialist clinicians in the neuro-oncology field, and under an Investigational New Drug (IND) filing with the US Food and Drug Administration. The study is awaiting registration with clinicaltrials.gov, and will commence screening patients after the Easter holidays. Not all patients will qualify, and some may withdraw during the initial phase of the study. It is anticipated that the study will provide an initial data read-out in early calendar 2019.

Commencement of the trial follows the decision of the US FDA to grant orphan drug designation to GDC-0084 in glioblastoma in February 2018. Since in-licensing the program, Kazia has been working closely with clinicians and advisors to build a comprehensive development program which aims to move GDC-0084 towards a product registration in the swiftest and most effective way. To date, this has included extensive regulatory consultation, manufacture of drug product for use in the phase II clinical trial, optimization of the intellectual property portfolio, and implementation of additional animal studies to support the further development of the drug.

Kazia Chairman, Iain Ross, commented, “this is an important achievement for the organisation. Two years ago, Kazia was an early-stage preclinical company. We now have two high-quality assets in clinical trials: Cantrixil in phase I for ovarian cancer and GDC-0084 in phase II for glioblastoma. The Board and Management have completed a significant transformation of the organization so as to optimally support this clinical-stage portfolio, and we are now a lean, cost-effective, and highly-focused biotech.”

He added, “we continue to be pleased with progress on the phase I study of Cantrixil, and look forward to reporting initial data from this study, which we expect will occur in the second calendar quarter of 2018.”
