Summary

This trial is testing a new, personalized cancer vaccine given with another immunotherapy drug. The goal is to see if it's safe and effective in treating patients with advanced solid tumors.

Who is the study for?
Adults with advanced solid tumors that have spread and are not treatable by surgery. Participants must have a life expectancy over 6 months, adequate organ function, and agree to use effective contraception. They should be willing to provide tissue samples for research and not have other active cancers or severe diseases.
What is being tested?
The trial is testing the safety of a new personalized cancer vaccine combined with Pembrolizumab (an existing immunotherapy drug) in patients with various types of advanced solid tumors. The vaccine targets specific proteins on tumor cells to help the immune system fight cancer.
What are the potential side effects?
Possible side effects include reactions at the injection site, flu-like symptoms from the vaccine, and typical immunotherapy-related issues like fatigue, skin rash, diarrhea, liver inflammation from Pembrolizumab.

Awards & Highlights

No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.

Trial Design

1Treatment groups
Experimental Treatment
Group I: Treatment (cyclophosphamide, vaccine, pembrolizumab)Experimental Treatment4 Interventions
Patients receive cyclophosphamide IV on day -3. Patients then receive personalized neoantigen vaccine with sargramostim SC on days 1, 4, 8, and 15 of cycle 1 and day 1 of cycles thereafter. Patients also receive pembrolizumab IV over 30 minutes on day 1. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients may undergo blood sample collection during screening, cycle 1 days -3, 1, 8, 15, 22, cycles 2, 3, 4, 5, 7, 8 and 9+ day 1 and 30 days after last dose of GM-CSF or pembrolizumab and may undergo tissue biopsy during screening, week 25 or at the time of disease progression. Patients also undergo CT or MRI during screening, week 9 then every 9 weeks, and 30 days after last dose of GM-CSF or pembrolizumab.
