VB-111 in Combination With Nivolumab in People With Metastatic Colorectal Cancer (mCRC)
Phase II Trial of VB-111 in Combination With Nivolumab in Patients With Metastatic Colorectal Cancer (mCRC).
Background:
Gastrointestinal cancer is one of the most common cancers worldwide. Researchers think an unmet need exists to understand and improve treatment options. They want to see if a combination of drugs can help people with metastatic colorectal cancer.
Objective:
To see if using a combination of Vascular Biogenics (VB)-111 and nivolumab is safe and will cause colorectal tumors to shrink.
Eligibility:
People ages 18 and older with microsatellite stable colorectal cancer that has spread to the liver
Design:
Participants must consent to sample collection protocol 11C0112.
Participants will be screened with:
Blood tests
Scans
Tumor samples. If these are not available, participants will have a biopsy.
Before they start treatment and with every treatment cycle, participants will have:
Physical exams
Blood tests
Heart tests
Before they start treatment and every 4 cycles, participants will have computed tomography (CT) or magnetic resonance imaging (MRI) scans. For these, they will lie in a machine that takes pictures of the body. For the MRI, a soft padding or coil will be placed around their head.
Participants will have biopsies before they start therapy. They will have them again after 2 6 weeks on study.
On day 1 of 14-day cycles, participants will get one or both study drugs by vein.
After they finish treatment, participants will have monthly visits for 3 months. They will have a physical exam and blood tests.
If participants stop treatment for reasons other than their disease getting worse, they will have scans about every 8 weeks. This will continue until their disease gets worse.
Participants will be contacted by phone or email every 6 months. This will continue for life.

Detailed Description
Background:
- Immune based approaches in gastrointestinal (GI) cancers have unfortunately- with the notable exception of immune checkpoint inhibition in microsatellite instable (MSI-H) disease and gastric cancer-been largely unsuccessful. The reasons for this are unclear but no doubt relate to the fact that in advanced disease GI cancer appears to be less immunogenic, as evidenced by the lack of infiltrating lymphocytes with advancing T stage as well as an immunosuppressive tumor micro-environment.
- Vascular Biogenics (VB)-111 is an anti-angiogenic agent comprising of a nonreplicating E1 deleted adenovirus type 5 which contains a modified murine preproendothelin (PPE) promoter and Fas-chimera transgene
- VB-111 has been tested and shows promise in glioblastoma, ovarian and thyroid tumors
- Nivolumab is a human monoclonal antibody directed against programmed cell death protein 1 (PD-1).
- The aim of this study is to study the effects of VB-111 in colorectal cancer (CRC) and to evaluate whether the antitumor immunity induced by VB-111 therapy can be enhanced by PD-1 inhibition.
Objectives:
- To determine the safety and tolerability of VB-111 in combination with nivolumab in patients with refractory, metastatic CRC
- To determine Best Overall Response (BOR) (partial response (PR) + complete response (CR)) according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1) of combined treatment of VB-111 and nivolumab in patients with refractory, metastatic CRC.
Eligibility:
- Histopathological confirmation of colorectal cancer metastatic to the liver
- Patients must have progressed on > 2 lines of standard of care chemotherapy for colorectal cancer or been intolerant of chemotherapy or refused prior chemotherapy.
- Patient's tumors must be documented to be microsatellite stable (MSS).
- Patients must have at least 1 focus of metastatic disease that is amenable to pre-and on-treatment biopsies and be willing to undergo this.
- All patients enrolled will be required to have measurable disease by RECIST v 1.1 criteria.
Design:
- The proposed study is a phase II study of VB-111 in combination with immune checkpoint inhibition (nivolumab) in patients with metastatic CRC
- Treatment will be delivered in cycles consisting of 2 weeks with VB-111 given every 6 weeks and nivolumab given every 2-week until progression or unacceptable toxicity.
- Disease status evaluation will be done every 8 (+/- 1) weeks after the start of study therapy.

- Patients who have had anti-vascular endothelial growth factor (VEGF) therapy within 4 weeks prior to enrollment.
- Patients currently on a corticosteroid dose greater than physiologic replacement dosing defined as 10 mg of cortisone per day or its equivalent.
- Patients with known brain metastases because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
- Patients with signs of liver failure, e.g., clinically significant ascites, encephalopathy, or variceal bleeding within 6 months prior to enrollment.
- Prior major liver resection: remnant liver <50% of the initial liver volume. Patients with a biliary stent can be included.

Such diseases should be excluded because of the risk of recurrence or exacerbation of disease.
Of note, patients with vitiligo, endocrine deficiencies including thyroiditis managed with replacement hormones including physiologic corticosteroids are eligible. Patients with rheumatoid arthritis and other arthropathies, Sjogren's syndrome and psoriasis controlled with topical medication and patients with positive serology, such as antinuclear antibodies (ANA), anti-thyroid antibodies should be evaluated for the presence of target organ involvement and potential need for systemic treatment but should otherwise be eligible.

- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations (within timeframes identified in the bullets below) that would limit compliance with study requirements.

- Myocardial infarction within 6 months prior to enrollment
- History of myocarditis
- Sustained hypotension (<90/50 mmHg) or uncontrolled hypertension (>160/100 mmHg)
- Stroke within 6 months prior to enrollment.
- Patients with proliferative and/or vascular retinopathy.
- Significant vascular disorders (e.g., aortic aneurysm, requiring surgical repair or recent peripheral arterial thrombosis) within 6 months prior to enrollment.
- History of hemoptysis (> 1/2 teaspoon of bright red blood per episode) or active gastrointestinal (GI) bleeding within 6 months prior to enrollment.
- Evidence of a bleeding diathesis or significant coagulopathy (in the absence of therapeutic anticoagulation)
- History of abdominal fistula or gastrointestinal perforation within 6 months prior to enrollment.
- Human immunodeficiency virus (HIV)-positive patients are excluded because HIV causes complicated immune deficiency and study treatment can possess more risks for these patients.
- Prior autologous or allogenic hematopoietic stem cell transplant.
- Subjects with ascites.
- Patients with unhealed surgical wounds for more than 30 days.
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to nivolumab or VB-111.
- History of severe hypersensitivity reaction to any monoclonal antibody.
- Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years prior to enrollment.
- Pregnant women are excluded from this study because nivolumab and VB-111 potential for teratogenic or abortifacient effects are unknown. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with nivolumab and VB-111, breastfeeding should be discontinued if the mother is treated with nivolumab and/or and VB-111.

Best overall response is defined as the best response recorded from the start of the treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started) assessed by the Response Evaluation Criteria in Solid Tumors (RECIST)v1.1.
Complete Response (CR) is disappearance of all target lesions.
