Clinical Trials

This is a two arm Phase III trial in first and second-line HER2 negative patients with locally recurrent or metastatic breast cancer. The primary endpoint is overall survival (OS), and the objective is to test for the superiority of eribulin mesylate over standard weekly paclitaxel. Patients will be randomized between the experimental and control arm with equal allocation (1:1) within strata defined by prior adjuvant taxanes, hormone receptor status, and line of therapy. Subjects will continue protocol directed therapy until documentation of disease progression, development of unacceptable toxicity, or withdrawal of consent. Those who discontinue study treatment without radiological progression will be followed with repeat imaging studies every 12 weeks. All subjects will be followed until death, withdrawal of consent, or study termination.

The purpose of this study is to determine the safety of 5 fraction vs. 25 fraction radiation to the whole breast or post-mastectomy chest wall/reconstructed chest with regional nodal radiation.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving them in different ways after surgery may kill more tumor cells. It is not yet known which chemotherapy regimen is more effective in treating older women with breast cancer. PURPOSE: This randomized phase III trial is studying different combination chemotherapy regimens to see how well they work in treating older women who have undergone surgery for breast cancer.

The primary purpose of this study is to examine the effects of abemaciclib on the CD8/FOXP3 ratio in chemotherapy-resistant triple negative breast cancer (TNBC) patients following neoadjuvant chemotherapy.

This research is being done to evaluate the safety and tolerability of the new drug, axatilimab, in combination with olaparib (a standard of care treatment) in Breast Cancer 1/2 genes (BRCA 1/2) and PALB2 associated HER2-negative metastatic breast cancer. The names of the study drugs involved in this study are: * Axatilimab (a type of antibody) * Olaparib (a type of PARP inhibitor)

This record is for the Prospective treatment arm, the Retrospective cohort will have a seperate protocol and IRBe record.

The GORE Tissue Reinforcement for Breast Reconstruction (TRBR) research study will look at breast reconstruction during mastectomy procedures. There will be two arms in this study, a Prospective Arm, where data will be collected for a new medical device called the Tissue Reinforcement for Breast Reconstruction (TRBR) Device and a Retrospective Arm where data will be collected from subjects who have previously had surgery and received no additional tissue reinforcement in their breast reconstruction surgery. This research study will look at the safety of the Study Device and the success of the participants breast reconstruction. The Study Device is investigational, which means it has not yet been used nor approved by the FDA for this treatment. The data collected in this study will be compared to the data collected in the Retrospective Arm.

Each year, the number of breast cancer survivors who choose post-mastectomy breast reconstruction keeps rising. Among women who elect to pursue breast reconstruction, approximately 75% will choose prosthetic breast reconstruction. Implant-based breast reconstruction is frequently achieved in two-stages. The first stage consists of the placement of a tissue expander after mastectomy. This is followed by a period of weekly tissue expansions that can last several months. In the second stage, the tissue expander is removed in a surgical procedure and replaced with a permanent breast implant. Tissue expansion is a well-established breast reconstruction technique characterized by high success rates and high patient satisfaction. Despite the well-recognized advantages of this successful breast reconstruction technique, the subpectoral placement of a tissue expander is associated with significant pain and discomfort in the immediate post-operative period and during the phase of tissue expansion. Pectoralis major muscle spasm is a frequently reported problem during tissue expansion. Legeby et al. recently showed that women who underwent prosthetic breast reconstruction had higher pain scores and took more analgesics that those who did not choose post-mastectomy reconstruction.

In the past 10 years, publications on the use of BTX-A for pain relief in a wide array of clinical conditions have increased tremendously. BTX-A is one of the neurotoxins produced by Clostridium botulinum bacteria. By reversibly inhibiting neurotransmitter release, BTX-A has both analgesic and paralytic properties. The analgesic action of BTX-A was initially thought to be related to its effects on muscular contraction. However, a recent in vitro study of embryonic rat dorsal neurons did confirm that BTX-A inhibits release of substance P, a neurotransmitter associated with pain and inflammatory reactions. The presence of analgesic properties of BTX-A is increasingly supported by several clinical observations: pain relief with BTX-A injections has been reported for migraine headaches, chronic pelvic, chronic tennis elbow, and post-operative pain control for lower limb lengthening correction, among others.

This aspect has never been studied in breast cancer survivors who elect to pursue breast reconstruction with tissue expanders. Furthermore, physical function outcomes are important to consider with BTX-A use because the link between temporary muscle paralysis and improvements in participation in daily activities is not a given.

The investigators propose to complete a double-blinded prospective randomized controlled trial of women undergoing unilateral and bilateral mastectomies with immediate placement of tissue expanders, to establish the efficacy and safety of BTX-A in alleviating pain and in improving physical well-being during the expansion period.

This randomized phase II/III trial studies how well standard of care therapy with stereotactic radiosurgery and/or surgery works and compares it to standard of care therapy alone in treating patients with breast cancer that has spread to one or two locations in the body (limited metastatic) that are previously untreated. Standard of care therapy comprising chemotherapy, hormonal therapy, biological therapy, and others may help stop the spread of tumor cells. Radiation therapy and/or surgery is usually only given with standard of care therapy to relieve pain; however, in patients with limited metastatic breast cancer, stereotactic radiosurgery, also known as stereotactic body radiation therapy, may be able to send x-rays directly to the tumor and cause less damage to normal tissue and surgery may be able to effectively remove the metastatic tumor cells. It is not yet known whether standard of care therapy is more effective with stereotactic radiosurgery and/or surgery in treating limited metastatic breast cancer.

The purpose of this trial is to determine the patient's pathological response after hypofractionated radiotherapy to the whole breast based on a specimen after surgery. The analysis of tumor mutation may lead to a better understanding of the effect of radiotherapy in breast cancer.

The purpose of this study is to evaluate combining endocrine therapy with CDK4/6 inhibition along with trastuzumab in ER+/ human epidermal growth factor receptor 2 (HER2)+ early stage breast cancer in order to influence estrogen receptor (ER) signaling.
