About

This is a Phase I multicenter, open label, nonrandomized study of enadenotucirev administered in combination with nivolumab in subjects with metastatic or advanced epithelial tumors (with focus on CRC, SCCHN, escalation phase), not responding to standard therapy.

Full description

To characterise the safety and tolerability of enadenotucirev administered in combination with nivolumab in subjects with metastatic or advanced epithelial tumours.

A dose escalation phase is conducted in subjects with solid tumors of epithelial origin not responding to standard therapy to establish the MTD/MFD and optimum dosing schedule of the enadenotucirev and nivolumab combination treatment.

A dose expansion phase will further outline the dose level and schedule of enadenotucirev and nivolumab combination treatment and investigate signals of efficacy in three cohorts of subjects with specific epithelial tumour types.

Inclusion criteria

Adult males or females aged 18 years or over
Disease status: - Diagnosis of metastatic or advanced CRC, UCC, SCCHN, salivary gland cancer or NSCLC not responding to standard therapy or for whom no standard treatment exists
For patients who have received prior PD-1 / PD-L1 therapy (Cohorts 7A and 7B and dose expansion phase only): Prior PD-1 / PD-L1 inhibitor therapy in current line of treatment for ≥6 weeks and ≤4 months, with best response of stable disease or progressive disease
ECOG performance status 0 or 1
Predicted life expectancy of 3 months or more
Ability to comply with study procedures in the Investigator's opinion
Recovered to Grade 1 from the effects (excluding alopecia) of any prior therapy for their malignancies Adequate lung function
Adequate renal function
Adequate hepatic function
Adequate bone marrow function
Adequate coagulation tests: PT and aPTT within normal range or international normalized ratio (INR) ≤1.5
Meeting reproductive status requirements
Subjects must provide written informed consent to participate
Willing to consent to tumour biopsies during the study

Exclusion criteria

Pregnant or breastfeeding females
Known history or evidence of significant immunodeficiency due to underlying illness
Splenectomy
Prior allogeneic or autologous bone marrow or organ transplantation
Any history of renal disease, renal injury or auto-immune disease.
History of idiopathic pulmonary fibrosis, drug induced pneumonitis, evidence of active pneumonia or pneumonitis on computed tomography scan
Clinically or radiologically suspected, or evidence of, lymphangitic carcinomatosis
Active infections requiring antibiotics, physician monitoring or recurrent fevers >100.4˚F (38.0˚C) associated with a clinical diagnosis of active infection
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 or HCV antibody test indicating acute or chronic infection. Positive test for HIV or AIDS; testing is not required in the absence of history
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
For Cohort 1 to 6:Prior treatment with PD-1 and programmed death ligand (PD-L)1 inhibitors
For Cohorts 7A and 7B and dose expansion phase: History of Grade >2 or currently uncontrolled immune-related AEs while being treated with PD-1 / PD-L1 inhibitors
For Cohorts 7A and 7B and dose expansion phase: Patients with progressive disease with ≥50% increase in disease burden from start of PD-1 / PD-L1 inhibitor therapy in the most recent line of treatment are excluded
Major surgery or treatment with any chemotherapy (bisphosphonate therapy or treatment with receptor activator of nuclear factor kappa-Β l(RANK)-ligand inhibitors for metastatic bone disease is permitted), biologics for cancer or investigational therapy in the 28 days before the first dose of study treatment (patients with prior cytotoxic or investigational products <3 weeks prior to study treatment might be eligible after discussion between the Investigator and Medical Monitor, if toxicities from the prior treatment have been resolved to NCI CTCAE Grade 1 and decision is supported by the half-life of previous therapy). All toxicities attributed to prior anti-cancer therapy other than alopecia must have resolved to Grade 1 or baseline before the first dose of study treatment. Patients with toxicities attributed to prior anti-cancer therapy which are not expected to resolve and result in long lasting sequelae, such as neuropathy after platinum based therapy, are permitted to enroll Note: This does not apply to anti-PD-1 / PD-L1 if in the patient's current line of therapy, and anti-PD-1 / PD-L1 treatment may continue during screening
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 metastasis that is symptomatic and/or requires treatment. Patients with brain metastases are eligible if these have been locally treated (surgery, radiotherapy). There must also be no requirement for immunosuppressive doses of systemic corticosteroids (>10 mg/day prednisone equivalent) for at least 14 days before the first dose of study treatment. Both surgery and or radiotherapy must have been completed at least 2 weeks before first dose of study 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
Known allergy to enadenotucirev, nivolumab or their excipients
Any other medical or psychological condition that would preclude participation in the study or compromise ability to give informed consent
Dependence on continuous supplemental oxygen use
History of myocardial infarction or significant cardiovascular or cerebrovascular event in the 12 months before the first dose of study treatment
An increased risk due to tumour flare, as assessed by the Investigator (e.g. an initial increase in tumour size that may lead to intestinal obstruction, obstruction of the ureter or airway)
Penetrating tumour infiltration of major blood vessels, pericardium, gastrointestinal tract or other hollow organs that may lead to perforation due to tumour necrosis
History of DVT or pulmonary embolus in the 12 months before the first dose of study treatment
History of significant bleeding requiring hospitalization in the 12 months before the first dose of study treatment
Patients receiving therapeutic or prophylactic anticoagulation therapy
