Clinical Trials Project Target Discovery Preclinical Phase Ia Ph Ib Ph 2a Ph 2b Hep C p7 HIV Vpu Dengue M protein

==> picture [720 x 66] intentionally omitted <==

• Leading cause of chronic liver disease and transplants

• 180 m people infected worldwide (3% world population); 130 m are chronically infected

• 4 m patients in US (2.7 m chronically infected)

• 70% will develop liver diseases including cirrhosis and liver cancer

• Currently only 2.6% are treated each year

• Standard of care is interferon and ribavirin

• Up to 50% patients don’t respond to current treatment

• Significant side effect profile – high drop out rate

• Documented need for new, safer drugs

==> picture [720 x 66] intentionally omitted <==

Worldwide market ~US$2.8 billion; predicted to expand to >US$10 billion as new, safer drugs enter the market.

USA and Europe represent major markets but other, larger markets are emerging.

• New investigational oral drug for treating HCV infection

• First in class; targets p7 protein – essential for virus assembly and release

• Phase Ia (BIT225-001) – single dose study (35 – 600 mg) in healthy volunteers.

• Completed 2007

• 48 subjects

• BIT225 well-tolerated at doses up to 600mg

• Good bioavailability and half-life

==> picture [720 x 66] intentionally omitted <==

• Phase Ib (BIT225-003) – 7-day dosing with drug or placebo in 18 HCVinfected patients.

• Completed 2009

• 18 subjects

• Different genotypes and past-treatment history

• BIT225 significantly reduced HCV levels compared to placebo (p=0.0002)

• First indication that BIT225 could target HCV in vivo

BIT225 and Hepatitis C – Phase 2a

0 8 pts 8 pts 8 pts	2 4 Ph II Trial Period	Weeks 44 wks Trial design

	BIT225 (200 mg) + IFN/rib	Interferon + Ribavirin
	BIT225 (400 mg) + IFN/rib	Interferon + Ribavirin

• Protocol BIT225-005

• Pts randomly assigned to receive either placebo or BIT225 twice daily for 28 days commencement of standard combination therapy for Hep C (IFN/ribavirin)

• Patients continue after 28 days just on IFN/ribavirin as part of their standard treatment (external to Phase II trial)

• 24 patients, genotype 1

• Trial commenced Sept 2010 in Thailand; Completed Aug 2011

==> picture [720 x 67] intentionally omitted <==

• Preliminary results released Oct 2011

• BIT225 treatment resulted in ~1 log (i.e.10-fold) improvement in viral load reduction over and above IFN and ribavirin over the 28 days of treatment

• Clear demonstration that this first in class, direct-acting antiviral drug has good antiviral activity

• Confirmed preclinical efficacy studies that demonstrated synergism with IFN and ribavirin

• Data to be presented at HepDART in early December

==> picture [720 x 66] intentionally omitted <==

• Documented need for new antiviral drugs; licensing space is still very active

• 18 Oct 2011 - Roche acquired Anadys (NASDAQ:ANDS), with Phase 2b and Phase 1 HCV programs, for US$230 million

• BIT225 is well-positioned

• First in class drug

• Potential to be used with either IFN/ribavirin i.e. current treatment, or

• To be combined with other new direct-acting antiviral drugs for HCV treatment in new, yet to be approved cocktails

• Currently conferring with clinical and industry experts to determine most suitable next steps in development of BIT225 as an anti-HCV drug

==> picture [720 x 64] intentionally omitted <==

BIT225 and HIV

• Current international focus on strategies for elimination or cure of HIV

• Current HIV treatments do not completely eliminate virus from the body

• Biotron is well positioned with its HIV drug targeting virus in the reservoir cells

• Prevents production of infectious virus in reservoir cells

• Potential to eliminate this long-lived source of virus in the body

• Commenced a Phase 1b/2a trial in HIV-positive patients in September 2011

• Anticipate completion of enrolment in 1Q2012

				Days	Days
	0			10			20
8 pts			Placebo			Drug-free follow-up
16 pts			400 mg BIT225			Drug-free follow-up

• Protocol BIT225-004

• 24 subjects to be enrolled

• Treatment-naïve, high virus load and relatively high T-cell counts

•Trial designed to demonstrate proof-of-concept i.e. can reduce HIV loads in HIV-infected reservoir cells in man

==> picture [718 x 66] intentionally omitted <==

HIV

• 39.5 million people living with HIV/AIDS

• 4.3 million people newly infected with HIV p.a.

• 2.9 million people die of HIV/AIDS-related causes p.a.

• US market alone worth >US$3.3 billion p.a.; global market is worth >US$9 billion p.a.

• Reservoir elimination field is still in its infancy

• Most programs are still at research/university stage of development

• Biotron’s approach is novel and relatively advanced

• If successful, anticipate that BIT225 could be used in combination with existing anti-retroviral therapies

==> picture [720 x 64] intentionally omitted <==

• The US and European regulatory agencies (FDA and EMEA) have clearly stated their enthusiasm for trialing and developing new HCV drugs in hard to treat populations

• These include the HIV/HCV co-infected population

• Up to 30% of HIV-infected are also HCV-infected

• Have a worse prognosis and outcome

• No other drugs target both viruses

• Biotron has a unique position as BIT225 works on both HIV and HCV

==> picture [720 x 64] intentionally omitted <==

• HIV

• BIT225 has shown activity in dendritic cells – the first cells to be exposed to HIV at the point of infection

• Exploring whether BIT225 could be used to prevent establishment of HIV infection (oral microbicide)

• Dengue • Research program with Universities of Wollongong and Canberra (ARC Linkage Grant scheme)

• Targeting M protein of Dengue (new target)

• Designing, synthesising and testing new compounds targeting Dengue virus

• Aim to use data from this current project to leverage funding for extended studies

==> picture [720 x 64] intentionally omitted <==

• Formulation studies of BIT225 into capsule/tablet format

• 3-month toxicology studies in animals

• Investigate potential trial design(s) for next trial(s)

– 3-month dosing with SOC (+/-IFN)

• Studies against other genotypes

– Combination with other new classes of anti-HCV drugs

– Studies in difficult to treat populations especially HIV/HCV co-infected

• Aim is to continue to add value to programs as proceed towards commercialisation
