Description

Summary

This study will evaluate the safety, tolerability and preliminary efficacy and also pharmacokinetics, immunogenicity and other pharmacodynamic effects to elucidate the mechanism of action of NG-350A, either alone or in combination with a check point inhibitor, in patients with advanced or metastatic epithelial tumours.

Official Title

A Multicentre, Open Label, Non-randomised First in Human Study of NG-350A (Monotherapy), and NG-350A With a Check Point Inhibitor in Patients With Metastatic or Advanced Epithelial Tumours

Details

Phase Ia of this study is a dose escalation phase, investigating NG-350A administration by intravenous (IV) infusion, either alone or in combination with a check point inhibitor. Phase Ib of this study comprises of a Combination Dose Efficacy Expansion with NG-350A in combination with a check point inhibitor.

You CAN'T join if...

  1. Prior or planned allogeneic or autologous bone marrow or organ transplantation
  2. Splenectomy
  3. 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
  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
  5. Patients who have active 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
  6. 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
  7. Treatment with any live, live attenuated or COVID-19 vaccine in the 28 days before the first dose of NG 350A
  8. COVID-19 vaccines known not to be based on an adenoviral vector (e.g. mRNA vaccines) are not subject to the 28-day exclusion (see exclusion criterion 7)
  9. Treatment with any other vaccine (including known non-adenoviral COVID-19 vaccines) in the 7 days before first dose of NG-350A
  10. History of prior Grade 3-4 acute kidney injury or other clinically significant renal impairment
  11. History of clinically significant interstitial lung disease or non-infectious pneumonitis

  17. . 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)
  18. . Use of the following prior therapies/treatments:
  19. Treatment with any other anti CD40 antibody at any time
  20. 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.

  24. . 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. Patients with toxicities (other than renal toxicities) attributed to prior anti-cancer therapy that are not expected to resolve and result in long lasting sequelae, such as neuropathy after platinum-based therapy, are permitted to enrol
  25. . Treatment with the antiviral agents ribavirin, adefovir, lamivudine or cidofovir within 7 days prior to the first dose of study treatment; or pegylated interferon (PEG-IFN) in the 14 days before the first dose of study treatment

  27. . 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
  28. . Symptomatic brain metastases or any leptomeningeal metastases that are symptomatic and/or require treatment. Patients with brain metastases are eligible if these have been treated (surgery, radiotherapy). Both surgery and or radiotherapy must have been completed at least 2 weeks before first dose of study treatment. There must also be no requirement for immunosuppressive doses of systemic corticosteroids (>10 mg/day prednisone equivalent) for at least 2 weeks before the first dose of study treatment
  29. . 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
