  • ECOG performance status 0 or 1
  • Predicted life expectancy of ≥6 months
  • Adequate lung reserve (Oxygen saturation on ambient air at sea level ≥95% or the equivalent based on altitude (i.e. ≥90% at 5000 feet))
  • Adequate renal function:
    • Creatinine ≤1.5 × upper limit of normal (ULN) and estimated glomerular filtration rate (eGFR) ≥60 mL/minute/1.73m2 (or measured creatinine clearance ≥60 mL/minute)
    • Spot albumin-to-creatinine ratio (ACR) for proteinuria at screening and baseline ≤30 mg/g. Patients with a spot ACR >30 mg/g who undergo a subsequent 24-hour urinary protein test with a result of <1 g/24 h may be included

  • Meeting reproductive status requirements:
    • Must not be pregnant or breastfeeding
    • Female patients of childbearing potential, must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotrophin) within 24 hours before the first dose of study treatment
    • Female patients of childbearing potential who are heterosexually active must agree to use a highly effective method of contraception to prevent pregnancy, for the duration of study treatment and 6 months following the last dose of study treatment. Female patients who are continuously not heterosexually active are exempt from contraceptive requirements, but must still undergo pregnancy testing
    • Female patients who are heterosexually active, irrespective of childbearing status, must ensure their male partner agrees to use a condom with spermicide during sexual intercourse for the duration of study treatment and 6 months following the last dose of study treatment
    • Patients must be willing to refrain from egg donation during treatment and for at least 6 months following the last dose of study treatment
    • Male patients who are sexually active with men or women must agree to use a condom with spermicide during intercourse for the duration of study treatment and 6 months following the last dose of study treatment. In addition, patients must be willing to refrain from sperm donation during this time.
  • Exclusion Criteria:
  • Prior or planned allogeneic or autologous bone marrow or organ transplantation
  • Splenectomy
  • Active infections requiring antibiotics, physician monitoring or systemic therapy within 1 week of the anticipated first dose of study drug, or recurrent fevers (>38.0˚C) associated with a clinical diagnosis of active infection
  • Treatment with the antiviral agents: ribavirin, adefovir, lamivudine or cidofovir within 10 days prior to the first dose of study treatment; or pegylated interferon in the 4 weeks before the first dose of study treatment
  • Active viral disease or positive test for hepatitis B virus using hepatitis B surface antigen test or positive test for HCV using HCV ribonucleic acid (RNA) or HCV antibody test indicating acute or chronic infection. Positive test for HIV or AIDS
  • Patients who have active, known or suspected autoimmune disease that has required systemic therapy in the past 2 years, are immunocompromised in the opinion of the Investigator, or are receiving systemic immunosuppressive treatment a. Patients with vitiligo, type I diabetes mellitus, asthma/atopy, residual hypothyroidism due to autoimmune disease (which only requires hormone replacement therapy), or conditions not expected to recur in the absence of an external trigger are permitted to enrol providing they comply with the other eligibility criteria relating to renal function. Use of inhaled corticosteroids, local steroid injection, or steroid eye drops is allowed
  • Treatment with any live, live-attenuated or COVID-19 vaccine in the 30 days before the first dose of NG-641 or nivolumab (COVID-19 vaccines known not to be live/live-attenuated or based on an adenoviral vector (e.g. mRNA vaccines) are not subject to the 30-day exclusion)
  • Treatment with any other vaccine (including known non-live/live-attenuated and non-adenoviral COVID-19 vaccines) in the 7 days before the first dose of NG-641
  • History of prior Grade 3-4 acute kidney injury or other clinically significant renal impairment

  • Grade 3 or 4 gastrointestinal bleeding (or risk factors for gastrointestinal bleeding) or haemoptysis in the 3 months before first dose of study treatment, or any history of bleeding requiring an investigative procedure (e.g. endoscopy), transfusion or hospitalisation in the 12 months before the first dose of study treatment
  • Tumour location/extent considered by the Investigator to present a significant risk if tumour flare or necrosis were to occur (e.g. an initial increase in tumour size that may lead to intestinal, airway or ureter obstruction, or penetrating tumour infiltration of major blood vessels, or other hollow organs potentially at risk of perforation)
  • Use of the following prior therapies/treatments:
    • Treatment with any other enadenotucirev-based virus (parent virus or transgene-modified variants), or fibroblast activation protein (FAP) targeting agent at any time
    • Treatment with an investigational or licensed anti-cancer monoclonal antibody (mAb), immune checkpoint inhibitor, immune stimulatory treatment or other biological therapy in the 28 days prior to the first dose of study treatment.
  • Prior anti-PD-1/PD-L1 therapy is permitted without a 'washout' phase c. Treatment with an investigational or licensed chemotherapy, targeted small molecule or other investigational drug in the 14 days or five half-lives (whichever is shorter) before the first dose of study treatment d. Major surgery in the 28 days before the first dose of study treatment e. Radiation therapy in the 14 days before the first dose of study treatment f. Treatment with complementary medications (e.g. herbal supplements or traditional Chinese medicines) to treat the disease under study within the 14 days prior to first study treatment. Such medications are permitted if they are used as supportive care g. Bisphosphonate therapy or treatment with Receptor Activator of Nuclear factor Kappa-Β (RANK)-ligand inhibitors for metastatic bone disease is permitted
  • All toxicities attributed to prior anti-cancer therapy (including radiation therapy) other than alopecia must have resolved to Grade 1 or baseline before the first dose of study treatment

  • Discontinuation from prior treatment with an immune therapy due to a Grade ≥3 immune-related AE, or any history of life-threatening toxicity related to prior immune therapy
  • Other prior malignancy active within the previous 3 years, except for local or organ confined early stage cancer that has been definitively treated with curative intent, does not require ongoing treatment, has no evidence of residual disease and has a negligible risk of recurrence and is therefore unlikely to interfere with the primary and secondary endpoints of the study, including response rate and safety
  • Symptomatic brain metastases or any leptomeningeal metastases that are symptomatic and/or requires treatment
  • Any serious or uncontrolled medical disorder that, in the opinion of the Investigator or the Medical Monitor, may increase the risk associated with study participation or study treatment administration, impair the ability of the patient to receive protocol therapy or interfere with the interpretation of study results
