Ascend Company Highlights

Ascend is an immuno-oncology company targeting regulated cell death and immune pathways with:

• a high value lead opportunity: lead candidate addresses a major high-value clinical need in

nodular BCC patients considered to be poor candidates for surgery

• a clinically de-risked lead with prospects of an expedited pivotal program: lead candidate has

good safety and clinical benefit results in 3 different skin cancers

• phase 2 data available shortly: current Phase 2 study in nodular BCC will have top-line interim

data in November 2016 and final data in 1H, 2017

• lead candidate with multiple follow-on opportunities: potential to address multiple high-

value follow-on indications in recurrent ovarian cancer and recurrent cutaneous squamous cell carcinoma

*Based on regulatory precedence for Aldara in Superficial BCC patients who were not good surgery candidates

The Opportunity: nodular Basal Cell Carcinoma

• Basal cell carcinoma is the most common cancer

worldwide arising in ~3 Million patients annually (~2 million with nodular BCC and ~1 million with superficial BCC)

• Prognosis is good if excised but if untreated can cause

significant morbidity/disfigurement

• Surgical excision is the main treatment option for nBCC
• It is estimated that around 25-30% of nBCC patients

(over 500,000 patients annually) can be considered poor candidates for surgery A significant clinical and commercial opportunity in high-risk nBCC

Most nBCC lesions occur

• n the face, head and

neck, making excision and wound closure more difficult If untreated BCCs become locally invasive and can cause extensive disfigurement Excision margins of 2 to 5 mm (all around the whole of the

• uter tumour mass) are appropriate for most BCC resections

The risk of recurrence is determined by the patients age, immune status, and the location and subtype (histology) of the tumour

Current Non-surgical Treatment Options

Existing options have major disadvantages or are clinically inadequate

Small Lesion Large Lesion Comments

Photodynamic Therapy Generally a poor choice Generally a poor choice Poor efficacy for High-risk nBCC 5-FU Poor choice Poor choice Poor efficacy for High-risk nBCC Radiotherapy Generally good clinical clearance Generally good clinical clearance Risk of radiation induced secondary cancers Aldara Generally a poor choice Should not be used Poor efficacy for High-risk nBCC Cryosurgery Generally fair choice Generally a poor choice Poor efficacy for High-risk nBCC Vismodegib/Sonidigib (Smoothened inhibitors) Not recommended Recommended for Locally advanced basal cell skin cancer patients with residual disease in whom surgery and radiation are contraindicated Major adverse effects (hair loss, muscle cramps, taste disturbance) Secondary resistance

Rationale for ASN-002 in Nodular BCC

Strong Biological Rationale for the use of Interferon in BCC:

• Interferons can be effective in up to 100%* of nBCC patients
• Recombinant Interferon therapy requires multiple daily injections (e.g., schedules of 9-12 administrations)
• A single injection of ASN-002 can result in sustained local expression of Interferon for up to 2 weeks

Favorable pathway to registration

• Availability of nodular BCC patients in Australia and US – many productive sites available
• Histological clearance an FDA approvable endpoint (prospects for shorter on study time)
• No registered therapeutics approved for nodular BCC in target patient setting^
• First mover advantage in high-risk BCC indication possible
• Vehicle-controlled Phase 3 possible (lower hurdle for demonstrating clinical superiority)

DNA launched SRIPs (Single Round Infectious Particles)

• SRIP DNA vectors can be conjugated to targeting moieties (e.g., antibody)
• Transfected SRIP DNA vectors produce infectious particles that can transduce cells within the TME
• SRIP RNA encode a self-amplifying replicon RNA leading to high levels of gene expression
• SRIP RNA can encode immunotherapy payloads such as cytokines, chemokines, antibodies

SRIPs are viral vectors produced within the tumour microenvironment launched from a DNA plasmid

Delivery to stromal or neo-vasculature within the TME SRIPs can encode immuno-oncology genes SRIP DNA can be conjugated to various targeting moieties

ASN-008 is being developed to induce highly immunogenic cell death
