What You Need to Know Before You Apply

What is the purpose of this trial?

In the first part of this study we found the highest dose of the vaccine that did not have too many side effects. We are now trying to find out what effects the vaccine has when given at the same dose to all patients. The main treatment in this protocol is a vaccine. It is called a " bivalent vaccine" which means it has 2 antigens. An antigen is a specific protein on the surface of a cell. The antigens are called GD2L and GD3L.We want the vaccine to cause the patient's immune system to make antibodies against the antigens. Antibodies are made by the body to attack cancer (and to fight infections). If the patient can make antibodies against the 2 antigens in the vaccine, those antibodies might also attach to neuroblastoma cells because a lot of each antigen is on neuroblastoma (and very little on other parts of the body). Then, the attached antibodies would attract the patient's white blood cells to kill the neuroblastoma. This protocol also uses β-glucan which is a kind of sugar from yeast. β-glucan is taken by mouth and can help white blood cells kill cancer. The best way to get the body to make antibodies against the 2 antigens is to link each antigen to a protein called KLH (which stands for: keyhole limpet hemocyanin) and to mix them with a substance called QS-21. But it is hard to get enough QS-21 so we are using an identical substance called OPT-821, which we can get easily in large amounts for use in patients.

Are You a Good Fit for This Trial?

This trial is for high-risk neuroblastoma patients who've had previous immunotherapy, are in first or subsequent remission, and have normal organ function tests. They must be able to follow the study plan and not have allergies to vaccine components like KLH or OPT-821.

What Are the Treatments Tested in This Trial?

Interventions

  • Bivalent Vaccine with OPT-821 Adjuvant
Trial Overview The trial is testing a bivalent vaccine with two antigens linked to KLH protein, combined with an adjuvant (OPT-821) and oral β-glucan. The goal is to stimulate the immune system to produce antibodies that target neuroblastoma cells.
