CD40 Agonist, Flt3 Ligand, and Chemotherapy in HER2 Negative Breast Cancer

United States30 participantsStarted 2022-04-20

Plain-language summary

This research study is being done to find out if the immunotherapy drugs called CDX-301 and CDX-1140 in combination with the standard chemotherapy treatment pegylated liposomal doxorubicin (PLD, Doxil) are safe and effective at controlling the cancer in patients with metastatic triple Human Epidermal Growth Factor Receptor 2 (HER2) negative breast cancer, and to determine a safe dose and treatment schedule of the three drugs. This research study will also test how your immune system responds to these treatments alone and in combination.

Inclusion Criteria: * Unresectable Stage III or Stage IV HER2 negative breast cancer (either triple negative or hormone receptor positive) * Triple negative breast cancer for this study is defined as estrogen receptor \<10%, progesterone receptor \<10% by immunohistochemistry, and HER2- negative by Herceptest (0 or 1+) or not amplified by in situ hybridization as per routine clinical testing. * Hormone receptor positive breast cancer for this study is defined as either estrogen receptor ≥10% or progesterone receptor ≥10% by immunohistochemistry, and HER2- negative by Herceptest (0 or 1+) or not amplified by in situ hybridization as per routine clinical testing. * Age 18 years or older * Performance status ECOG 0-2 * Life expectancy ≥ 12 weeks * Documented progressive disease, based on radiographic, clinical or pathologic assessment, during or subsequent to last anticancer therapy. Patients who need to change systemic therapy for other indications such as toxicity that are otherwise eligible for this study may enroll with approval of the lead principal investigator. * For triple negative breast cancer patients, subject is in first to fourth line setting of treatment for metastatic or unresectable disease, and have received 0 to 3 prior regimens for metastatic or unresectable disease. * For hormone receptor positive breast cancer patients, subjects must have received prior cyclin dependent kinase inhibitor in the metastatic setting. They may have received up to 3 prior li…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Safety (tolerability) of the drug combination of CDX-1140, CDX-301 and PLD as measured by the number of participants with Dose Limiting Toxicity (DLT)
