Paxalisib Pan - PI3K & mTOR Inhibition Advantage Paxalisib is a comprehensive pathway and biology modulator, not simply a broader PI3K inhibitor. o Not built around a mutation - defined strategy – Narrows the addressable biology to tumors where a specific mutation is the dominant driver – Cancer biology, especially in more aggressive and heterogeneous settings, is often broader – Pathway dependence can arise not only from PIK3CA mutations, but also from PTEN loss, upstream signaling, downstream escape, and other network - level mechanisms o Dose de - escalation is critical for epigenetic effect o Enhances immune visibility through viral mimicry pathways and supports synergy with immune checkpoint inhibition o May allow a wider range of tumors where PI3K signaling is functionally relevant, including wild - type disease, to be addressed o May help address resistance mechanisms that can emerge when only one node of the pathway is targeted Kazia believes dual inhibition is necessary for broader biological effects, including functional epigenetic reprogramming and immune reinvigoration. PI3K and mTOR together influence tumor state, immune signaling, and resistance biology. 14

Paxalisib: Advanced Breast Cancer Paxalisib Potential in Breast Cancer 1. Cancer.org 2024 2. Data Bridge Market Research Paxalisib inhibits PI3K / mTOR, a central oncogenic pathway driving cell survival and proliferation, resistance to endocrine, HER2 - targeted, and cytotoxic therapies, and immune suppression within the tumor microenvironment (TME). PI3K / mTOR signaling is frequently dysregulated in breast cancer and associated with tumor proliferation, disease progression, and therapeutic resistance. Brain metastases develop in ~25 – 46% of patients with metastatic TNBC over the disease course, with ~10 – 15% present at initial metastatic diagnosis. PI3K / mTOR in Breast Cancer Paxalisib Opportunity Breast Cancer • >300,000 new cases of invasive BC in the US Triple Negative Breast Cancer • Rare, fast - growing, and aggressive form of breast cancer • Accounts for approximately 10 - 15% of all breast cancer • 5 - year survival rate of 3 - 5% • Predicted market growth of $1.5B by 2030 18 The most diagnosed cancer and leading cause of death in women

Why Isn't Everyone Doing This? • Access through leading research from QIMR Berghofer • First - in - class optimized approach to targeting SETDB1 • Complements Kazia's existing focus on reprogramming cancer behavior Why Kazia? What is SETDB1? Why Does This Matter? • A protein that cancer cells use to hide from the immune system • Turns off signals that would normally alert the body to attack the tumor, acting like an internal "off switch" • Many cancers become resistant to immunotherapy because they can no longer be "seen" by the immune system. By targeting SETDB1, we aim to: o Turn those signals back on o Make tumors more visible o Help existing therapies work again • Targets a major global unmet need : aggressive, treatment - resistant cancers • Novel first - in - class therapeutic and companion biomarker platform with lead indications in NSCLC , CRC , and metastatic breast cancer (TNBC) • Many patients still do not respond or develop resistance to immunotherapy • SETDB1 works inside the cell nucleus , making it difficult to target • It has only recently been recognized as a key driver of immune resistance • New technologies (like advanced peptides) are now making this possible 45
