Clinical Trial Summary

UV1 is a therapeutic cancer vaccine that has been explored in prostate, lung cancer, in combination with ipilimumab in malignant melanoma and in combination with pembrolizumab in metastatic melanoma. This study will explore the Efficacy and Safety of UV1 administered with GM-CSF in combination with nivolumab and ipilimumab.

Description:

This is a randomized, open label study to investigate efficacy and safety of UV1 vaccination in combination with nivolumab and ipilimumab as first line treatment of adult patients with histologically confirmed unresectable metastatic melanoma.

Patients in the experimental arm will receive 8 UV1 vaccinations over 4 cycles of nivolumab and ipilimumab. Patients in the control arm will receive 4 cycles of nivolumab and ipilimumab. Patients in both arms will start maintenance therapy 6 weeks after the last dose of induction therapy, nivolumab at a dose of 480 mg every 4 weeks.

All patients will be followed up until death or until the end of the study.

To support the Extended Exploratory Cohort of the study, an additional 20 patients at selected sites will be enrolled in a single arm UV1 cohort for collection of additional biological material. These patients are in addition to the 156 randomized patients in the main part of the study.

9. Known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies).

10. History of or active hepatitis B (hepatitis B surface antigen reactive) or active hepatitis C (hepatitis C virus antibody).

11. Women who are breastfeeding.

12. Prior systemic treatment for unresectable stage IIIB D or unresectable stage IV malignant melanoma.

13. Systemic corticosteroid treatment (doses exceeding 10 mg daily of prednisone or equivalent) or any other form of immunosuppressive treatment within 7 days prior to the first dose of induction therapy.

14. Receipt of a live vaccine within 30 days prior to start of induction therapy.

15. Receipt of any other investigational treatment within 4 weeks of the first dose of induction therapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Immunological mechanisms	To elucidate the immunological mechanisms underlying the interplay between immune activation provoked by UV1 vaccination and inhibition of tumor resistance mechanisms and peripheral immune tolerance induced by checkpoint blockade and how biological factors affect the efficacy of the combination therapy. This will be evaluated by change in immune- and tumor-related gene, cell, and protein profiles in blood over time in both treatment arms (analysis of plasma proteins, cell-free plasma DNA, and cellular genomic DNA).	Time from randomization to end of study, estimated up to 27 months
Primary	PFS per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1	Compare progression free survival (PFS) of UV1 vaccination in combination with nivolumab and ipilimumab to that of nivolumab and ipilimumab	Time from randomization to progressive disease (PD) or death from any cause, estimated up to 27 months
Secondary	Overall Survival	Compare Overall Survival of UV1 vaccination in combination with nivolumab and ipilimumab to that of nivolumab and ipilimumab .	Time from randomization to death from any cause /follow-up until 70 PFS, estimated up to 51 months
Secondary	ORR per RECIST 1.1	Compare the objective response rate (ORR) of UV1 vaccination in combination with nivolumab and ipilimumab to that of nivolumab and ipilimumab.	Time from first ORR or death from any cause, estimated up to 27 months.
Secondary	DOR per RECIST 1.1	Compare duration of response (DOR) of UV1 vaccination in combination with nivolumab and ipilimumab to that of nivolumab and ipilimumab.	Time from first CR or PR to PD or death from any cause, estimated up to 27 months.
Secondary	Evaluation of Adverse events, vital signs, laboratory assessments and ECOG performance status	Compare the safety of UV1 vaccination in combination with nivolumab and ipilimumab to that of nivolumab and ipilimumab. Safety will be listed and summarized descriptively by treatment arm comparing number of participants with observation and changes from baseline and at each visit related to AEs, deaths, vital signs (weight (kg), systolic and diastolic blood pressure (mmHg), pulse rate (bpm), body temperature (°C)), laboratory assessments and ECOG performance status (Grade 0 - Grade 5).	Time from randomization to end of study, estimated up to 27 months
