Breast Cancer Clinical Trials in Portland, OR

The primary objective of this study is to compare the progression-free survival (PFS) between sacituzumab govitecan-hziy (SG) versus treatment of physician's choice (TPC) in participants with previously untreated, locally advanced, inoperable or metastatic triple-negative breast cancer whose tumors do not express programmed cell death ligand 1 (PD-L1) or in participants previously treated with anti-programmed cell death (ligand or protein) 1 (Anti-PD-(L)1) Agents in the early setting whose tumors do express PD-L1.

A multicenter trial to investigate TBio-4101, an autologous, neoantigen-selected, tumor-reactive TIL product, in patients with advanced solid malignancies. Read Less

This Phase 1/2 study will assess the safety, tolerability, and efficacy of multiple dose levels of PC14586 (INN: rezatapopt) alone (monotherapy) and in combination with pembrolizumab in participants with advanced solid tumors containing a TP53 Y220C mutation. Read Less

This is a Phase III, randomized, open-label, 3-arm, multicenter, international study assessing the efficacy and safety of Dato-DXd with or without durvalumab compared with ICT in participants with stage I to III TNBC with residual invasive disease in the breast and/or axillary lymph nodes at surgical resection following neoadjuvant systemic therapy.

Patients with advanced HER2+ breast cancer on maintenance trastuzumab/pertuzumab or T-DM1 with 1st or 2nd intracranial disease event (brain metastases) and stable extracranial disease will be enrolled. They will receive local therapy with stereotactic radiosurgery ± surgical resection if indicated followed by enrollment. Patients will continue standard of care trastuzumab/pertuzumab or T-DM1 with the addition of tucatinib. Hormone receptor positive patients requiring endocrine therapy should continue. Study treatment will continue until disease progression or intolerable side effects. Patients on trial with extracranial disease progression with stable intracranial disease should continue tucatinib into next line of therapy. Read Less

This is a Phase III, global, randomized, open-label, multicenter, study evaluating the efficacy and safety of adjuvant giredestrant compared with endocrine therapy of physician's choice in participants with medium- and high-risk Stage I-III histologically confirmed estrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-negative early breast cancer. In addition, an open-label exploratory substudy will explore the safety and efficacy of giredestrant in combination with abemaciclib in a subset of the primary study population. Read Less

The study is intended to show superiority of AZD9833 in combination with CDK4/6 inhibitor (palbociclib, abemaciclib or ribociclib) versus aromatase inhibitors (anastrozole or letrozole) in combination with CDK4/6 inhibitor in patients with hormone receptor-positive (HR-positive), human epidermal growth factor receptor 2-negative (HER2-negative) metastatic breast cancer with detectable ESR1 mutation.

This Phase III Trial evaluates whether breast conservation surgery and endocrine therapy results in a non-inferior rate of invasive or non-invasive ipsilateral breast tumor recurrence (IBTR) compared to breast conservation with breast radiation and endocrine therapy. Read Less

This Phase III trial compares the recurrence-free interval (RFI) among patients with early-stage, low risk HER2+ breast cancer who undergo breast conserving surgery and receive HER2-directed therapy, and are randomized to not receive adjuvant breast radiotherapy versus those who are randomized to receive adjuvant radiotherapy per the standard of care. Read Less

This Phase III Trial will determine whether adjuvant chemotherapy (ACT) added to ovarian function suppression (OFS) plus endocrine therapy (ET) is superior to OFS plus ET in improving invasive breast cancer-free survival (IBCFS) among premenopausal, early- stage breast cancer (EBC) patients with estrogen receptor (ER)-positive, HER2-negative tumors and 21-gene recurrence score (RS) between 16-25 (for pN0 patients) and 0-25 (for pN1 patients).

The goal of this study is to find out if the experimental product, sacituzumab govitecan-hziy (SG) in combination with pembrolizumab given after surgery, is effective and safe compared to the treatment of physician's choice (TPC) which includes either pembrolizumab or pembrolizumab plus capecitabine in participants with triple negative breast cancer that still remains after surgery and pre-surgical treatment.

The purpose of this study is to determine the impact of pre-operative cryoablation, and immune checkpoint inhibition (ICI) on on 3-year Event Free Survival (EFS), in women with residual hormone receptor negative, HER2-negative ("triple negative") resectable breast cancer after taxane-based neoadjuvant chemotherapy.
