Safety and Efficacy of ASN-002 Combined With a Hedgehog Pathway Inhibitor

Inclusion Criteria: 1. Histologically confirmed previously untreated, BCC (nodular and superficial), 5-20 mm in maximum diameter, per the selection criteria for study BCC tumours. A punch biopsy (refer to study procedure manual for biopsy size selection) from the thickest part of all the target tumours is required for histological confirmation of BCC and to exclude BCC non-eligible subtypes. Note: If a patient has mix of nodular and superficial BCC tumours, at least one target tumour should be a nodular BCC. 2. Removal of \< 25% of the area of each biopsied tumour by initial biopsy performed 1-12 weeks before Day 1. If the initial biopsy was performed \>8 weeks prior to screening, the investigator may re-biopsy the tumour, provided not \> 25% of the area of the original tumour is removed. Non-study tumours may be resected or treated at the discretion of the Investigator prior to study entry or if they develop during the study. 3. Hedgehog pathway inhibitor treatment naïve. 4. Acceptable general health as determined by the investigator, i.e. no serious or active medical or psychiatric illness or recreational or therapeutic drug or alcohol use that, in the opinion of the Investigator, would interfere with treatment, assessment or compliance with the protocol, ability to provide informed consent, or patient safety. 5. 18 years of age or older. 6. Eastern Cooperative Oncology Group (ECOG) performance status 0, 1 or 2. 7. Screening laboratory values as follows: 1. Neutrophil count \> 1500/mm3 2. Haemoglobin \> 9 g/dL 3. Platelet count \>100,000/mm3 4. Prothrombin INR \< 1.5 5. Total bilirubin \< 1.5 X upper limit of normal (ULN), except in the case of known Gilbert's syndrome 6. Aspartate transaminase (AST), alanine transaminase (ALT) or alkaline phosphatase (ALP) \< 2X ULN 7. Creatinine \< 1.5 X upper limit of normal (ULN) 8. Female patients who are documented infertile, postmenopausal for at least 1 year, surgically sterile or using acceptable and highly effective birth control for the duration of the study and for at least 3 months after last administration of the study treatments. 9. Male patients with female partners of child bearing potential, agreement to use two adequate contraception methods while being on vismodegib and for 3 months of completion. agreement not to donate semen for 3 months after completion of vismodegib. 10. Written informed consent prior to initiation of study-specified procedures. 11. Able and willing to comply with all study requirements, including surgical removal of tumour/tumour site at completion of study. 12. Baseline tissue sample adequate for determination of histological or other biomarkers. Exclusion Criteria 1. Known or suspected metastatic disease or other active, invasive malignancy. 2. Female patients of childbearing potential who are lactating or pregnant (negative serum pregnancy test needed prior to dosing). 3. Clinically active or uncontrolled skin disease or tattoos that would interfere with evaluation of the area surrounding the target tumour (e.g. eczema, unstable psoriasis, xeroderma pigmentosa). 4. Known history of sensitivity to any of the ingredients in ASN-002 and any Hh pathway inhibitors. 5. Immunocompromised (e.g. known Hepatitis B or C infection, HIV infection) or receiving or expected to receive an immunomodulating agent (including immunosuppressive agents, cytotoxic drugs, biological agents, immunoglobulins, interferon or other immune or cytokine-based therapies. Use of inhaled or oral corticosteroids at doses higher than physiological replacement doses is an exclusion criterion). 6. Has received or is expected to receive treatment with psoralen plus UVA or UVB therapy within 6 months of the Screening visit. 7. Any prior systemic anti-tumour therapy or local treatment for target tumours prior to first dose. 8. History of immunological disorder, severe allergic reaction, moderate or severe asthma or known history of anaphylaxis or any other serious adverse reactions to any medication. 9. Any experimental or investigational agents within one month of first ASN-002 injection. 10. Any prior exposure to TG1041, TG1042 (ASN-002), any other adenoviral-based experimental agent, or any form of gene therapy within 6 months of first dose of vismodegib in the study. 11. Any prior exposure to vismodegib or any other Hh inhibitor within 6 months of first dose in the study. 12. Current therapy with any medications recognized to cause rhabdomyolysis or a prior history of rhabdomyolysis.
