Methodology:
This study will evaluate ASN-002 (in the dose range 0.5 to 1.5x10(11) vp/mL) with the Hh inhibitor vismodegib (Erivedge®). The study will initially evaluate two Arms receiving 1.0 x 10(11) vp/injection, and following a safety review, may implement further arms in an adaptive study design.
Following screening and baseline biopsies for target and non-target tumours, eligible subjects will be enrolled in the study.
Cycle 1: Treatment with vismodegib (daily dose of 150 mg) for 4 weeks and ASN-002 for 3 weeks (i.e., three ASN-002 injections in total):
Clinical response will be assessed at Week 17, following which, the investigator may where clinically indicated, initiate Cycle 2.
Cycle 2: Treatment with vismodegib (daily dose of 150 mg) for 4 weeks, and one further injection with ASN-002:
Surgical excision for all patients will occur between Week 25 and Week 33 at the investigators discretion, and dependent on when patient completed study treatment (1 or 2 treatment cycles). Up to 10 BCCs to be excised including 3 target tumours. Excisions can be conducted over 2 visits as per Investigator's discretion.
The Investigator may enrol eligible patients parallel into either Arm 1 or Arm 2, based on the number of tumours present. Up to 10 study BCC tumours (up to 3 target and up to 7 non-target) will be selected per patient.
Following review of at least Week 5 data for N=6 patients in Arm 1 and Arm 2, further Arms with varying doses of ASN-002 (in the dose range 0.5x10(11) vp or 1.5x10(11) vp) may be explored at the discretion of the Safety Review Committee (SRC). Vismodegib or ASN-002 may be evaluated as monotherapies to provide control groups to allow comparison of treatment Arms.
Safety and clinical assessments will be performed at Weeks 1, 3, 4, 5, 7, 17, 25 to 33.
Histological response will be evaluated in all study tumours via excision between Week 25 and Week 33 (as per investigator's discretion).
Six patients will be recruited to each Arm of the study, each Arm may be expanded to 12 patients at the discretion of the SRC.

confirmed previously untreated, BCC (nodular and superficial), 5-20 mm in maximum diameter, per the selection criteria for study BCC tumours. A punch (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.

Exclusion Criteria
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Participants with 1 Target Tumour will receive 3 x ASN-002 1.0x10(11) Injections + VISMODEGIB (150 mg) daily for 4 weeks.
Biological: ASN-002
Participants with 3 or more Target Tumours will receive 3 x ASN-002 1.0x10(11) Injections (per tumour) + VISMODEGIB (150 mg) daily for 4 weeks.
Biological: ASN-002
Participants with 3 or more Target Tumours will receive 3 x ASN-002 1.5x10(11) Injections (per tumour) + VISMODEGIB (150 mg) daily for 4 weeks
Biological: ASN-002
ASN-002 has been designed for clinical applications, especially for intratumoral administration in the treatment of various cancers. This rAd vector delivers the gene of interest, in the case of ASN-002 the human IFNγ gene, into target cells. The rAd vector in ASN-002 is replication deficient and although it infects cells, it is not able to replicate in the tumor or in normal human cells. The infected cells are able to transcribe and translate the IFNγ DNA leading to a sustained local concentration of IFNγ in the tumor mass that is designed to avoid high levels of systemic IFNγ that may be lead to unacceptable toxicity.
Incidence of ASN-002 related Adverse Events in patients with previously untreated nBCC
Incidence of Adverse Adverse events will be monitored
