Breast Cancer Clinical Trials in Seattle, WA

This phase III trial compares the effect of active symptom monitoring and patient education to patient education alone in helping young women with stage I-III breast cancer stay on their hormone therapy medicines. The patient education tool contains interactive weblinks which provide patients with education material about breast cancer and side effects of therapy. Symptom monitoring is a weblink via email or text message with questions asking about symptoms. Hormone therapy for breast cancer can cause side effects, and may cause some women to stop treatment early. Asking about symptoms more often may help women keep taking hormone therapy medicines.

This phase III trial compares the effects of shorter chemotherapy (chemo)-immunotherapy without anthracyclines to usual chemo-immunotherapy for the treatment of early-stage triple negative breast cancer. Paclitaxel is in a class of medications called anti-microtubule agents. It stops cancer cells from growing and dividing and may kill them. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. It may also lower the body's immune response. Docetaxel is in a class of medications called taxanes. It stops cancer cells from growing and dividing and may kill them. Doxorubicin is an anthracycline chemotherapy drug that damages DNA and may kill cancer cells. Pembrolizumab may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Shorter treatment without anthracycline chemotherapy may work the same as the usual anthracycline chemotherapy treatment for early-stage triple negative breast cancer. Read Less

A Phase 1B/2A study will be conducted to establish safety and dose level of AMXT 1501 dicaprate in combination with IV DFMO, in cancer patients. Read Less

This phase II trial studies the effect of sacituzumab govitecan in treating patients with HER2-negative breast cancer that has spread to the brain (brain metastases). Sacituzumab govitecan is a monoclonal antibody, called sacituzumab, linked to a chemotherapy drug, called govitecan. Sacituzumab is a form of targeted therapy because it attaches to specific molecules on the surface of cancer cells, known as Trop-2 receptors, and delivers govitecan to kill them. Giving sacituzumab govitecan may shrink the cancer in the brain and/or extend the time until the cancer gets worse. Read Less

This is a Phase 3, open-label, randomized, clinical trial evaluating the efficacy and safety of gedatolisib plus fulvestrant with or without palbociclib for the treatment of patients with locally advanced or metastatic HR+/HER2- breast cancer following progression on or after CDK4/6 and aromatase inhibitor therapy.

This open-label, First-into-Human (FIH) study will evaluate the safety, tolerability, pharmacokinetics (PK) and early efficacy of AVA6000, a FAP-activated pro-drug of doxorubicin, in patients with locally advanced and/or metastatic solid tumours. In Phase Ia, using a 3+3 design, escalating doses of AVA6000 will be administered to patients with a range of solid tumour types to determine the maximum tolerated dose (MTD) and/or recommended Phase II dose (RP2D). In Phase 1b, the selected RP2D dose will be assessed in one to three tumour types. Read Less

This phase I trial studies the side effects and best dose of alpha-TEA when given together with trastuzumab and to see how well they work for the treatment of HER2+ breast cancer that does not respond to treatment (refractory) and has spread to other places in the body (metastatic). Anti-cancer treatment, such as alpha-TEA, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Alpha-TEA may also alter cancer growth by stimulating the body's immune response against the tumor. Trastuzumab is a form of "targeted therapy" because it works by attaching itself to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors. When trastuzumab attaches to HER2 receptors, the signals that tell the cells to grow are blocked and the cancer cell may be marked for destruction by the body's immune system. Giving alpha-TEA and trastuzumab may work better for the treatment of HER2+ refractory and metastatic breast cancer compared to usual treatment. Read Less

This is a Phase 3, open-label, randomized, clinical trial evaluating the efficacy and safety of gedatolisib plus fulvestrant with or without palbociclib for the treatment of patients with locally advanced or metastatic HR+/HER2- breast cancer following progression on or after CDK4/6 and aromatase inhibitor therapy. Condition or disease: Breast Cancer Intervention/treatment: Drug: Gedatolisib Drug: Palbociclib Drug: Fulvestrant Drug: Alpelisib Phase 3 Read Less

For patients with ER-positive, HER2-negative breast cancer, blockage of the ER pathway has been proven to be an effective anticancer approach. These patients showed good response to endocrine therapy. Fulvestrant, the approved SERD as monotherapy or in combination with CDK4/6 inhibitors, showed superior clinical benefit compared to other endocrine therapies. Fulvestrant exhibits differential mechanism of action from other endocrine therapy, such as tamoxifen, aromatase inhibitors, which indicates that direct blockage of ER might derive better clinical activity. However, due to its route of administration by intramuscular injection, the clinical application is limited, especially with long term use. In addition, a higher dose of fulvestrant at 500 mg showed better overall survival than the lower dose at 250 mg, suggesting that more profound ER pathway modulation could derive better clinical benefit. Therefore, a SERD with improved oral bioavailability and good safety profile which enables its overdose is anticipated to achieve a more satisfactory clinical outcome with better compliance of clinical use. Preclinical data indicates that ZB716 is a novel orally bioavailable, selective ERα degrader with full ER antagonism that demonstrates superior properties than Fulvestrant. Thus, it has a potential to be effective therapy for patients with ER-positive breast cancer. This is the first time ZB716 will be administered to humans. The principal aim of this study is to obtain safety and tolerability data when ZB716 is administered orally as monotherapy and in combination with palbociclib to subjects with ER-positive, HER2 negative advanced breast cancer. This information, together with the PK data, will help establish the doses and dosing regimen suitable for future studies in patients. The PD effect of ZB716 on the select biomarkers for cytochrome P450 (CYP)3A4 induction (4β hydroxycholesterol) and expression of ER, PgR, and Ki67 will also be investigated. The effect of ZB716 on antitumor activity as measured by objective response rate (ORR), clinical benefit rate (CBR), duration of response (DOR), and PFS rate will also be investigated. The study will also investigate the effects of food on the PK of ZB716 monotherapy. Read Less

This is a Phase 1, first-in-human, open-label dose-escalation study to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) and assess the DLT of JAB-3312. It is anticipated that approximately 24 subjects will be enrolled in the dose-escalation phase of the study. JAB-3312 will be administered orally once daily (QD) in 21-day treatment cycles. Read Less
