Brief summary: This is a multicentre, open-label, Phase I/II study of enadenotucirev in patients with either solid tumour of epithelial origin not responding to standard therapy or for whom no standard treatment exists (Phase I dose escalation stage Single cycle), mCRC not responding to standard therapy (Phase I dose escalation Repeat cycle cohort expansion stage ), mCRC not responding to standard therapy or advanced or metastatic bladder cancer not candidate for chemotherapy (Phase Ib) or mCRC in stable disease or partial response after 3-4 months of first line standard of care chemotherapy (Phase II).


Eligibility criteria: Inclusion Criteria:

* Patients must provide written informed consent

* For women who are not postmenopausal (24 months of amenorrhea) or surgically sterile (absence of ovaries and/or uterus): agreement to use two adequate methods of contraception, during the treatment period and for at least 3 months after the last dose of study drug
* For men: agreement to use a barrier method of contraception during the treatment period and for at least 6 months after the last dose of study drug
* At least 3 weeks since any dose of IV systemic chemotherapy and at least two weeks since any oral dose of capecitabine at the time of first administration of ColoAd1.

Phase I Specific Inclusion Criteria:

Dose Escalation Stage only (except Repeat Cycle Cohort):

- Solid tumour of epithelial origin not responding to standard therapy or for whom no standard treatment exists

Dose Expansion Stage Single Cycle and Dose Escalation Stage Repeat Cycle Cohort:

* mCRC not responding to standard therapy
* ≤ 3 prior lines of systemic therapy for advanced disease OR ≤ 4 prior lines of systemic therapy for advanced disease if one of the 4 lines was an anti EGFR therapy given as a single agent or combined to a previously administered chemotherapy regimen Phase Ib:mCRC not responding to standard therapy
* no more than 3 prior lines of systemic therapy for advanced disease OR no more than 4 prior lines of systemic therapy for advanced disease if one of the 4 lines was an anti EGFR therapy given as a single agent or combined to a previously administered chemotherapy regimen
* Advanced or metastatic UCC, who have received a maximum of one chemotherapy-containing regimen and a maximum of one other systemic treatment with biologic agents only.

Phase II Specific Inclusion Criteria:

* mCRC
* Have received 3 - 4 months of first line chemotherapy with either FOLFOX, FOLFIRI or CAPOX, with or without bevacizumab
* At least one measurable lesion according to RECIST 1.1 criteria
* Documented partial response or stable disease
* Eligible to receive chemotherapy with FOLFOX or CAPOX after a short chemotherapy interruption (3 to 4 weeks)

Exclusion Criteria for all Patients:

* Pregnant or breast feeding females;
* Known history or evidence of significant immunodeficiency due to underlying illness (e.g. human immunodeficiency virus \[HIV\]/acquired immunodeficiency syndrome \[AIDS\]) and/or medication (e.g. systemic corticosteroids, or other immunosuppressive medications including cyclosporine, azathioprine, interferons, within the past 4 weeks)
* Splenectomy
* Prior allogeneic or autologous bone marrow or organ transplantation
* Active infections requiring antibiotics, physician monitoring, or recurrent fevers \>38.0 degrees centigrade associated with a clinical diagnosis of active infection
* Active viral disease or known positive serology for HIV, hepatitis B or hepatitis C;
* Use of the following anti-viral agents: ribavirin, adefovir, lamivudine or cidofovir within 7 days prior to day 1; or pegylated interferon (PEG-IFN) (within 14 days prior to first administration of ColoAd1)
* Administration of an investigational drug within 28 days prior to first dose of ColoAd1
* Major surgery within 4 weeks or radiotherapy within 3 weeks prior to first dose of ColoAd1
* Another primary malignancy within the past 3 years (except for non melanoma skin cancer or cervical cancer in situ)
* Central nervous system (CNS) metastasis that is symptomatic and/or requires treatment
* Any condition or illness that, in the opinion of the Investigator or the medical monitor, would compromise patient safety or interfere with the evaluation of the safety of the drug
* Known allergy to treatment medication or its excipients
* Any other medical or psychological condition that would preclude participation in the study or compromise ability to give informed consent

Phase II Specific Exclusion Criteria:

* Progression on first line therapy
* A complete response on first line therapy
* Use of first line therapy for longer than 4 months
* Use of any first line treatment with a chemotherapy regimen other than FOLFOX, FOLFIRI or CAPOX (each with or without bevacizumab)
