What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a combination of a special vaccine, an immune booster, and a chemotherapy drug to prevent the return of triple negative breast cancer. It aims to help the immune system fight off cancer cells and use chemotherapy to kill any remaining ones.

Are You a Good Fit for This Trial?

This trial is for women aged 18+ with stage 1-3 triple negative breast cancer who've completed surgery and other treatments within the past 90 to 546 days. They must have a good performance status, adequate organ function, and no evidence of metastatic disease or recurrence. Women must not be pregnant, nursing, immunocompromised on antiretroviral therapy, or have active autoimmune diseases.

Inclusion Criteria

My breast cancer was surgically removed, is not spread, and tests negative for ER, PR, and HER2.

I am female.

I finished my last breast cancer treatment between 3 and 18 months ago.

Exclusion Criteria

I am currently breastfeeding.

You have had a bad reaction to GM-CSF before.

I do not have any severe illnesses or social situations that would stop me from following the study's requirements.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants receive cyclophosphamide and either the multi-epitope folate receptor alpha peptide vaccine with sargramostim or a placebo vaccine with sargramostim. Treatment repeats every 28 days for cycles 2-7 and every 6 months for cycles 8-14.

Approximately 2 years

Follow-up

What Are the Treatments Tested in This Trial?

Interventions

• Cyclophosphamide
• Multi-epitope Folate Receptor Alpha Peptide Vaccine
• Sargramostim

Trial Overview The study tests if a vaccine made from white blood cells and tumor proteins plus GM-CSF (sargramostim) and cyclophosphamide can prevent cancer recurrence in patients post-surgery. Participants are randomly assigned to receive either this combination treatment or a placebo in an effort to stimulate the immune system against cancer cells.

How Is the Trial Designed?

Group I: Arm I (FRalpha peptide vaccine, sargramostim) Experimental Treatment 4 Interventions

Patients receive cyclophosphamide PO BID on days 1-7 and 15-21 of cycle 1 only. Starting cycle 2, patients receive multi-epitope folate receptor alpha peptide vaccine with sargramostim ID on day 1. Treatment repeats every 28 days for cycles 2-7 and every 6 months for cycles 8-14 in the absence of disease progression or unacceptable toxicity.

Group II: Arm II (placebo, sargramostim) Placebo Group 4 Interventions

Patients receive cyclophosphamide as in Arm I. Starting cycle 2, patients receive placebo vaccine with sargramostim ID on day 1. Treatment repeats every 28 days for cycles 2-7 and every 6 months for cycles 8-14 in the absence of disease progression or unacceptable toxicity.
