- Conditions
- Epithelial TumorMetastatic Cancer
- Interventions
- Biological: NG-350A plus Pembrolizumab
- Registration Number
- NCT05165433
- Lead Sponsor
- Akamis Bio
- Brief Summary
This is a phase 1a/1b, multicentre, open-label, non-randomized study of NG-350A in combination with pembrolizumab in patients with metastatic or advanced epithelial tumours.
- Detailed Description
Phase 1a will investigate NG-350A administration by intravenous (IV) infusion in combination with fixed-dose pembrolizumab in patients with metastatic or advanced tumours.
Phase 1b will further investigate the efficacy and safety of the selected dose regimen in up to three of the tumour types evaluated in Phase 1a.

-
Infectious or inflammatory bowel disease in the 3 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
-
Use of the following prior therapies/treatments :
- Treatment with any other enadenotucirev-based virus (parent virus or transgene-modified variants), or anti-CD40 antibody at any time
- Radiation therapy to the lung that is >30Gy within 6 months of the first dose of trial treatment
- 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
- 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

- 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 must have resolved to Grade 1 or baseline before the first dose of study treatment. (see protocol for exceptions)
-
Participants with a history of radiation pneumonitis are not eligible for inclusion
-
