Brief Summary:
To characterise the safety and tolerability of NG-641 in patients with metastatic or advanced epithelial tumours.

Condition or disease Intervention/treatment Phase
Metastatic Cancer Epithelial Tumor Biological: NG-641 Phase 1

Detailed Description:

To characterise the safety and tolerability of NG-641 in patients with metastatic or advanced epithelial tumours.

The Phase Ia part of the study is a dose escalation and dose expansion phase investigating NG-641 administration by intratumorural injection (IT) and intravenous (IV) infusion in a range of tumour types

The Phase Ib part of the study is to investigate safety and efficacy of NG-641 as monotherapy or in combination with chemotherapy agents and/or checkpoint inhibitors in separate efficacy cohorts of patients with specific epithelial tumour types.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 128 participants
Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Multicentre, Open-label, Non-randomised First in Human Study of NG-641, an Oncolytic Transgene Expressing Adenoviral Vector, in Patients With Metastatic or Advanced Epithelial Tumours (STAR)
Actual Study Start Date : January 23, 2020
Estimated Primary Completion Date : December 31, 2022
Estimated Study Completion Date : December 31, 2022

Arm Intervention/treatment
Experimental: Intratumoural
In the IT cohort, patients will receive a single dose of NG-641 by IT injection on Day 1. The dose given to each patient will be dependent on the size of the tumour lesion to be injected.
Biological: NG-641
NG-641 is an oncolytic adenoviral vector which expresses a FAP-TAc antibody together with an immune enhancer module (CXCL9/CXCL10/IFNα).

Experimental: Intravenous
In the IV cohort, patients will receive a single cycle of study treatment, with three single doses of NG-641 on Days 1, 3 and 5 by IV infusion.
Biological: NG-641
NG-641 is an oncolytic adenoviral vector which expresses a FAP-TAc antibody together with an immune enhancer module (CXCL9/CXCL10/IFNα).




Primary Outcome Measures :
  1. Incidence of adverse events (safety and tolerability) in study NG-641 [ Time Frame: End of study treatment visit, Day 85 ]
    Assess the safety and tolerability of NG-641 by review of adverse events including serious adverse events (SAEs), adverse events meeting protocol defined DLT criteria, severe adverse events, adverse events leading to study treatment or study discontinuation, and adverse events resulting in death.

  4. a) For patients undergoing surgical excision/resection of tumour lesion(s):

    • Tumour deemed accessible and safe for biopsy by the Investigator
    • Patient able to undergo surgical procedure and appropriate anaesthesia
    • Willing to consent for baseline biopsies and surgical procedure b) For patients not undergoing surgical excision/resection:
    • Tumour accessible for biopsy and a biopsy deemed safe by the Investigator
    • Willing to consent to tumour biopsies
  5. ECOG performance status 0 or 1
  6. Predicted life expectancy of 3 months or more
  7. Ability to comply with study procedures in the Investigator's opinion
  8. Adequate renal function
  9. Adequate hepatic function
  10. Adequate bone marrow function
  11. Prothrombin time and aPTT time within normal range and international normalised ratio ≤1.5, as appropriate
  12. Meeting reproductive status requirements
  13. Phase Ia - Dose Expansion Phase only: at least one measurable site of disease according to RECIST Version 1.1 criteria

Exclusion Criteria:

  1. Known history or evidence of significant immunodeficiency due to underlying illness
  2. Splenectomy
  3. Active infections requiring antibiotics, physician monitoring or recurrent fevers (>38.0˚C) associated with a clinical diagnosis of active infection
  4. Active viral disease or positive test for hepatitis B virus using hepatitis B surface antigen test or positive test for hepatitis C virus (HCV) using HCV ribonucleic acid (RNA) or HCV antibody test indicating acute or chronic infection. Positive test for HIV or AIDS. Viral serology testing is not required in the absence of history
  5. History of chronic liver disease or evidence of hepatic cirrhosis
  6. History of idiopathic pulmonary fibrosis, pneumonitis (including drug-induced), organising pneumonia (bronchiolitis obliterans, cryptogenic organising pneumonia, etc.)
  7. Use of the following antiviral agents: ribavirin, adefovir, lamivudine or cidofovir within 7 days prior to the first dose of study treatment; or pegylated interferon in the 4 weeks before the first dose of study treatment
  8. Incomplete recovery from surgery, incomplete healing of an incision site or evidence of infection
  9. Any of the following in the 3 months before the first dose of study treatment: Grade 3 or 4 gastrointestinal bleeding/haemorrhage (unless due to resected tumour), treatment-resistant peptic ulcer disease, erosive oesophagitis or gastritis, infectious or inflammatory bowel disease, diverticulitis, pulmonary embolism or other uncontrolled thrombo-embolic event, history or evidence of haemoptysis or menorrhagia
  10. History of myocardial infarction or significant cardiovascular or cerebrovascular event in the 6 months before the first dose of study treatment

  21. Any history of renal disease or renal injury, coagulopathy or autoimmune disease
  22. 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
  23. Previous treatment with enadenotucirev or FAP targeting agents
  24. Known allergy to NG-641 transgene products or formulation
  25. Any other medical or psychological condition that would preclude participation in the study or compromise ability to give informed consent
