ASX/Media Release 13 March 2020

Antimicrobial platform update and launch of BTX 1801 clinical study

Key highlights

• Botanix has launched the next phase of development of its cannabinoid antimicrobial platform, with BTX 1801 initially targeting the prevention of surgical site infections (SSIs)

• New pre-clinical data demonstrates synthetic cannabidiol kills MRSA bacteria within 10 minutes by a novel mechanism of action and is a highly effective skin decolonisation agent

• New findings in combination with previous pre-clinical work, supports BTX 1801 as an ideal candidate for nasal decolonisation of Staph and MRSA for the prevention of SSIs

• Patients colonised with Staph at ICU admission are ~15 times more at risk, compared with non-colonised patients

• BTX 1801 Phase 2a clinical study is designed to generate proof of concept data to support rapid progression into a pivotal clinical study for FDA registration

Philadelphia PA and Sydney, Australia, 13 March 2020: Clinical stage synthetic cannabinoid company Botanix Pharmaceuticals Limited (ASX:BOT, “Botanix” or “the Company”) is pleased to announce significant progress with its antimicrobial platform and the commencement of a Phase 2a clinical study for its lead program BTX 1801, targeting the prevention of surgical site infections (SSIs).

A presentation providing an overview of anti-microbial resistance, pre-clinical data, target indication, Botanix’s antimicrobial platform and BTX 1801 clinical program is attached to this release.

Botanix Executive Chairman and President Vince Ippolito commented: “Antibiotic resistance continues to be a significant global health issue, with no new classes of antibiotics receiving FDA approval in more than three decades, despite the availability of significant funding initiatives and regulatory incentives.

“We are excited to be launching our first clinical program from our antimicrobial platform. The development of BTX 1801 for the prevention of SSIs diversifies our clinical pipeline and opens up a separate business line for Botanix outside our mature dermatology programs.”

One of the most troublesome resistance forming bacteria worldwide is Staphylococcus aureus ( ‘Staph’ ). In particular, Methicillin-resistant Staphylococcus aureus ( ‘MRSA’ or ‘Golden Staph’) is increasingly becoming a major global healthcare concern. Staph and MRSA are the leading cause of SSIs[1] and approximately 80% of SSIs are caused by the patient infecting themselves from their own nose, where Staph and MRSA can colonise. Global health authorities are now increasingly mandating the use of nasal decolonisation prior to surgery[2] , however antibiotics used for nasal decolonisation

==> picture [166 x 74] intentionally omitted <==

(e.g. Bactroban[TM] also known as mupirocin ) have seen a significant increase in the development of resistance, with some hospitals recording resistance rates as high as 95% making it less than ideal for use[2] . For additional information, refer to sections “Background – Anti-microbial resistance” and “First Target – Prevention of surgical site infection” in the attached presentation.

Peer reviewed publications also identify the significant risk that nasal colonisation with Staph presents to patients entering the intensive care unit (ICU) and who may require ventilation. Patients colonised with Staph at ICU admission, had an up to 15 times increased risk for developing pneumonia compared with non-colonised patients.[3]

New data released today, demonstrates synthetic cannabidiol rapidly kills MRSA bacteria within 10 minutes of exposure, by a novel mechanism of action, and without allowing resistance to develop. Furthermore, studies conducted by Botanix have shown that BTX 1801 is more effective than the market leading decolonisation agent, mupirocin , at decolonising MRSA and mupirocin resistance strains of MRSA were utilized in the industry-accepted pig skin decolonisation model. This combined with previous work showing that MRSA bacteria lack the ability to develop resistance to cannabidiol, makes BTX 1801 an ideal candidate for nasal decolonisation of Staph and MRSA for the prevention of SSIs. For additional information, refer to sections “Synthetic Cannabidiol’s Unique Anti-Microbial Effects” and “First Target – Prevention of surgical site infection” in the attached presentation.

In light of these results, Botanix has designed a double-blind, vehicle-controlled Phase 2a study to evaluate safety, tolerability and efficacy of two formulations of BTX 1801 to decolonise Staph and MRSA from the nose of healthy adults. Given one in three people in the community carry Staph and/or MRSA in their nose on average, this study population is ideal to establish proof of efficacy of BTX 1801, before moving into a pivotal clinical study involving patients undergoing surgery, for FDA registration. As a result, this clinical study can also be completed efficiently and is highly cost effective, as it will only involve 60 volunteers with a treatment period of five days. Final preparations for the BTX 1801 Phase 2a study are now underway and Botanix expects to enrol its first participants early in 2Q CY2020. For additional information, refer to “BTX 1801 Program” section in attached presentation.

About Botanix Pharmaceuticals

Botanix Pharmaceuticals Limited (ASX:BOT) is a clinical stage synthetic cannabinoid company based in Perth (Australia) and Philadelphia (USA) committed to the development of pharmaceutical products that are underpinned by science and supported by well-controlled randomised clinical trials. The Company has two separate cannabinoid development platforms, the first focusing on dermatology and the second on the development of antimicrobial products, both of which leverage the unique antiinflammatory, immune modulating and antimicrobial properties of cannabinoids, particularly synthetic cannabidiol. Botanix has an exclusive license to use a proprietary drug delivery system (Permetrex[TM] ) for direct skin delivery of active pharmaceuticals in all skin diseases.

The Company has announced data from its Phase 2 acne patient study and is preparing for the end of Phase 2 meeting with the FDA. A Phase 2 patient study in atopic dermatitis is now fully recruited with data planned for 1Q CY2020 and its new Phase 1b rosacea study recently received ethics approval. The Company is separately developing a pipeline of product candidates that leverages the antimicrobial properties of cannabinoids with first enrolment for BTX 1801 Phase 2a study for the prevention of surgical site infections expected in early 2Q CY2020

BACKGROUND

Staphylococcus aureus and methicillin resistant S. aureus (MRSA)

S. aureus infections cost the US economy up to US$10 billion per annum, with 40 million surgical patients “at risk” of S. aureus infections and 20 million patients at “high infection risk”[1]

==> picture [187 x 132] intentionally omitted <==

Slide 4

Slide 4

Staphylococcus aureus Slide 4 ( S. aureus or SA ) is a type of bacteria found on human skin, in the nose, armpit, groin and other areas and while it is the leading cause of skin and soft tissue infections, SA can also cause more serious infections, such as pneumonia, bloodstream infections, as well as heart, bone and joint infections[2]

Slide 4

Methicillin Resistant Staphylococcus aureus (MRSA) is a type of SA that is resistant to the antibiotics generally used to treat the bacteria. MRSA infections must therefore be treated with special antibiotics which limit treatment options, have more side effects and are very expensive[3]

How antibiotic resistance develops

When bacteria survive exposure to antibiotics that would normally eliminate them, these surviving bacteria grow and spread resistance – leading to the emergence of “superbugs”
