Equity Issuance

Under the terms of the transaction, Simcere will make a US$ 4 million (~AU$ 5.2 million) equity investment in Kazia, priced at a 20% premium to recent trading.

In relation to Kazia's 2016 purchase of Glioblast Pty Ltd, this transaction satisfies the conditions for Milestone 4 of that agreement and will therefore result in the issuance of escrowed ordinary shares to Glioblast shareholders, under terms previously disclosed by Kazia.

Paxalisib

Paxalisib is a brain-penetrant inhibitor of the PI3K / Akt / mTOR pathway, which is disordered in the vast majority of patients with glioblastoma, the most common and most aggressive form of primary brain cancer.

In a phase II study in patients with newly diagnosed glioblastoma with unmethylated MGMT promotor status, paxalisib has shown highly encouraging signals of clinical efficacy. In January 2021, patient recruitment commenced for paxalisib in the GBM AGILE platform study, which is expected to serve as the basis for registration in key territories.

Investor Conference Call

Kazia is pleased to invite investors to attend a conference call to further discuss the partnership with Simcere.

The call will be held on Tuesday 30 March 2021 at 8:00am, Sydney time (AEDT), which is 5:00pm on 29 March in New York (ET) and 2:00pm on 29 March in San Francisco (PT).
