Breast Cancer Clinical Trials in Santa Monica, CA

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 purpose of this clinical trial is to learn about the safety and effects of the study medicine (called PF-07220060 and PF-07104091) in people with breast cancer. This clinical study consists of 2 parts (part 1 and part 2). In part 1, we are seeking participants who: Have been diagnosed with Breast Cancer (BC) of either types: Have HR+, HER2- BC Refractory HR-positive/HER2-positive BC Have other solid tumors other than BC In part 2, we are seeking participants who: -Have HR-positive/HER2-negative BC Part 1 will include increasing doses of PF-07220060 with PF-07104091. In part 2, participants will take 1 of 2 study medicine combinations. This will help us decide the highest amount of study medicines that can be safety given to people. All participants in this study will receive PF-07220060 with PF-07104091 by mouth. We will compare participant experiences to help us determine if PF-07220060 with PF-07104091 is safe and effective. Participants will take part in this study for about 2 years. During this time, they will receive the study medicine, an x-ray imaging, and will be observed for safety and effects of the study medicines. Read Less

This phase III trial compares an additional support program (text message reminders and/or telephone-based counseling) with usual care in making sure breast cancer patients take their endocrine therapy medication as prescribed (medication adherence). Medication adherence is how well patients take the medication as prescribed by their doctors, and good medical adherence is when patients take medications correctly. Poor medication adherence has been shown to be a serious barrier to effective treatment for hormone receptor positive breast cancer patients. Adding text message reminders and/or telephone-based counseling to usual care may increase the number of days that patients take their endocrine therapy medication as prescribed. Read Less

This phase III trial studies how well trastuzumab emtansine (T-DM1) and tucatinib work in preventing breast cancer from coming back (relapsing) in patients with high risk, HER2 positive breast cancer. T-DM1 is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called DM1. Trastuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors, and delivers DM1 to kill them. Tucatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving T-DM1 and tucatinib may work better in preventing breast cancer from relapsing in patients with HER2 positive breast cancer compared to T-DM1 alone. Read Less

The main purpose of this study is to learn more about the safety, side effects, and effectiveness of LOXO-783. LOXO-783 may be used to treat breast cancer and other solid tumors that have a change in a particular gene (known as the PIK3CA gene). Participation could last up to 36 months (3 years) and possibly longer if the disease does not get worse. Read Less

The primary objective of this study is to compare the progression-free survival (PFS) between sacituzumab govitecan-hziy (SG) and pembrolizumab versus treatment of physician's choice (TPC) and pembrolizumab in participants with previously untreated, locally advanced inoperable or metastatic triple-negative breast cancer, whose tumors express programmed cell death ligand 1 (PD-L1).

This is a Phase Ib/II, open-label, multicenter, randomized umbrella study in participants with breast cancer. Cohort 1 will focus on participants with inoperable, locally advanced or metastatic, estrogen receptor (ER)-positive, HER2-negative breast cancer who had disease progression during or following treatment with a cyclin-dependent kinase 4/6 inhibitor (CDK4/6i; e.g., palbociclib, ribociclib, abemaciclib) in the first- or second-line setting. Cohort 2 will focus on inoperable, locally advanced or metastatic, ER-positive, HER2-positive breast cancer with previous progression to standard-of-care anti-HER2 therapies, of which one was a trastuzumab-and-taxane-based systemic therapy (including in the early setting if recurrence occurred within 6 months of finishing adjuvant therapy) and one was a HER2-targeting antibody-drug conjugate (ADC; e.g., ado-trastuzumab emtansine or trastuzumab-deruxtecan) or a HER2-targeting tyrosine kinase inhibitor (TKI; e.g., tucatinib, lapatinib, pyrotinib or neratinib). The study is designed with the flexibility to open new treatment arms as new treatments become available, close existing treatment arms that demonstrate minimal clinical activity or unacceptable toxicity, or modify the patient population. During Stage 1, participants in each cohort will be randomly assigned to treatment arms. Participants in the control or experimental arms who experience unacceptable toxicity, disease progression as determined by the investigator according to RECIST v1.1, or loss of clinical benefit as determined by the investigator during Stage 1 will be given the option of receiving a different treatment combination during Stage 2, provided they meet eligibility criteria and a treatment arm is open for enrollment. No Stage 2 treatment is currently available. Read Less

This is a prospective, registry study that will enroll all women with early stage breast cancer who will be treated with intraoperative radiotherapy (IORT) during breast-conserving surgery. The purpose of this study is to further validate the long-term effectiveness and safety of this treatment method. We aim to assess short and long-term patient outcomes associated with IORT, including perioperative complications, local and distance disease recurrences, as well as disease-free survival and overall survival.

The phase III trial compares the effect of pembrolizumab to observation for the treatment of patients with early-stage triple-negative breast cancer who achieved a pathologic complete response after preoperative chemotherapy in combination with pembrolizumab. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial may help researchers determine if observation will result in the same risk of cancer coming back as pembrolizumab after surgery in triple-negative breast cancer patients who achieve pathologic complete response after preoperative chemotherapy with pembrolizumab.

This is a Phase 1/2, multi-center, open-label, dose-escalation and expansion study to evaluate safety and tolerability, PK, pharmacodynamic, and early signal of anti-tumor activity of MDNA11 alone or in combination with a checkpoint inhibitor in patients with advanced solid tumors. Read Less

The goal of this interventional clinical trial is to learn about TNG260, a CoREST inhibitor, in combination with pembrolizumab in patients with advanced solid tumors with a known STK11 mutation. The main question[s] it aims to answer are: the recommended dose for Phase 2 to evaluate the safety and tolerability of the combination therapy to determine the pharmacokinetics of TNG260 to evaluate the initial antineoplastic activity Participants will receive study treatment until they experience an undesirable side effect, their disease progresses or until they withdraw consent.
