  Purpose
This research is being done because these viruses have been shown to shrink tumours in animals and human tumour samples by selectively killing cancer cells and creating an immune response to the tumour antigen contained in the viruses. This effect has been shown to increase when the AdMA3 virus is given first. It is not clear if this treatment will offer better results than standard treatment.

    • MG1MA3 when administered on day 1 & 4 following immunologic priming with AdMA3 (Arm C).
    • To confirm the safety profile of AdMA3 administration (Arm B).

  • Phase II: Objective tumour response rate (ORR) using RECIST v1.1. [ Time Frame: 16 weeks ]

Detailed Description:
The purpose of the first phase of this study (phase I) is to find the dose of a new therapy, the MG1 Maraba/MAGE-A3 (MG1MA3) virus that can be given alone and in combination with the Adenovirus/MAGE-A3 (AdMA3) virus. In the first part of the study, patients may receive the Maraba virus, the Adenovirus or both viruses. To identify the highest safe dose of the Maraba virus alone or in combination the study will start at a dose lower than the one that does not cause side effects in animals. Participants are given one or both of these therapies and are watched very closely to see what side effects they have and to make sure the side effects are not severe. If serious side effects are seen in patients at the first dose level, doses of MG1MA3 may be lowered in subsequent patients. If the side effects are not serious, then more potential participants are asked to join this study and are given higher doses. This will continue until the maximum feasible dose level is reached or one of the lower doses is found that causes serious but temporary side effects. Doses higher than that will not be given.

The regimen may have been cytotoxic chemotherapy, targeted therapy, hormonal therapy (for e.g. anastrozole) or immunotherapy providing considered a standard first line therapy. There is no limit to the number of prior regimens but investigators and their patients should carefully consider the likelihood of benefit of an immunologic therapy in heavily pretreated patients.
  • For phase II, patients may be enrolled prior to disease progression, provided they have completed their first line therapy as below and they have documented stable disease on two consecutive tumour assessments (i.e. do not have evidence of tumour regression from therapy):

    • NSCLC patients may be entered after a minimum of 4-6 cycles of first line combination chemotherapy; if the patient is >70 years a single agent regimen is acceptable. If the patient has documented EGFR or ALK mutations, treatment they may have received may include an EGFR inhibitor or ALK inhibitor as first line therapy.
