Brief Summary:
This clinical trial is looking at two new vaccines called ChAdOx1-MAGEA3-NYESO and MVA-MAGEA3 given with patients' standard of care treatment (chemotherapy and an immune checkpoint inhibitor).

Condition or disease Intervention/treatment Phase
Non-small Cell Lung Cancer (NSCLC) Biological: ChAdOx1-MAGEA3-NYESO Biological: MVA-MAGEA3 Combination Product: Standard of care treatment Phase 1 Phase 2

Detailed Description:

Patients with non-small cell lung cancer (NSCLC) will be entered into the trial as this tumour type is commonly known to have MAGE-A3 and NY-ESO-1 proteins on their cancer cells. The vaccines contain harmless parts of these proteins allowing them to show these proteins to the immune system. It is expected the immune system will 'learn' that these proteins are foreign to the body. The immune system should then attack the proteins on the cancer cells, killing them. It is expected the vaccines will help the chemotherapy and immune checkpoint inhibitor to work better.

This is a first-in-human clinical trial which has two stages:

  • A 'safety run in' stage where six evaluable patients will receive the trial vaccines with standard of care treatment to confirm they are safe before opening the next stage.
  • A 'rolling recruitment' stage where approximately 80 patients will be randomly allocated by computer (randomised) to one of two groups (arms). Patients in Arm A will receive the vaccines with their standard of care treatment and patients in Arm B will continue with their standard or care treatment alone. There is a 1 in 2 chance patients will receive the vaccines.

The main aims of the trial are to find out:

  • More about potential side effect of the vaccine and how they can be managed.
  • Whether the vaccines with standard of care treatment are better at shrinking cancer than just the standard of care treatment alone.
  • What happens to the vaccines inside the body.

    • Agree to use two forms of contraception (one effective form plus a barrier method) [oral, injected or implanted hormonal contraception and condom; intra-uterine device and condom; diaphragm with spermicidal gel and condom] or agree to sexual abstinence , effective from the first administration of ChAdOx1-MAGEA3-NYESO, throughout the treatment phase of the trial and for six months afterwards..
  6. Male patients with partners of child-bearing potential. However, those patients who meet the following points are considered eligible:

    • They agree to take measures not to father children by using a barrier method of contraception (condom plus spermicide) or to sexual abstinence6 effective from the Cycle 3 Day 1 of SoC treatment, throughout the treatment phase of the trial and for six months afterwards.
    • Men with partners of child bearing potential must also be willing to ensure that their partner uses an effective method of contraception for the same duration for example, hormonal contraception, intra uterine device, diaphragm with spermicidal gel or sexual abstinence.
    • Men with pregnant or lactating partners must be advised to use barrier method contraception (for example, condom plus spermicidal gel) to prevent exposure to the foetus or neonate.
  7. Major thoracic or abdominal surgery from which the patient has not yet recovered. Patients who have undergone other types of surgery which the Chief Investigator (CI) and Sponsor agree would not compromise patient safety on trial are eligible.
  8. Electrocardiogram (ECG) with clinically significant abnormalities or with QTcF interval (QT corrected using Fridericia's formula) >480 msec.
  9. At high medical risk because of non-malignant systemic disease including active uncontrolled infection.
  10. Historically known to be serologically positive for hepatitis B or human immunodeficiency virus (HIV). Patients with previous Hepatitis C exposure but no current infection are eligible to participate.
  11. Has an active autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed.
