Breast Cancer Clinical Trials in Los Angeles, CA

The goal of this clinical trial is to assess the efficacy of DB-1303/BNT323 compared with investigator's choice chemotherapy in terms of progression-free survival (PFS) by blinded independent central review (BICR) in the HR+, HER2-low (immunohistochemistry \[IHC\]2+/in situ hybridization \[ISH\]- and IHC 1+) population.

First in human study to evaluate the safety, tolerability, and pharmacokinetics (PK) of BBO-10203, a PI3Kα:RAS breaker, alone and in combination with trastuzumab in patients with advanced solid tumors. Read Less

This is an adaptive Phase 2, open-label, randomized, multi-center study evaluating up to 2 regimens of PCS6422 with capecitabine (Cap) vs. standard dose of Cap alone in patients with advanced or metastatic breast cancer. The goal of the study is to assess the efficacy and safety of PCS6422 + Cap as a treatment option for patients with advanced or metastatic breast cancer who are not eligible for anthracycline- or taxane-containing therapies, or other available therapies, including PD-1 or PARP inhibitors.

The goal of this clinical trial is to assess the efficacy, safety and tolerability of the combination of lasofoxifene and abemaciclib compared to fulvestrant and abemaciclib for the treatment of pre- and postmenopausal women and men who have previously received ribociclib or palbociclib-based treatment and have locally advanced or metastatic estrogen receptor positive (ER+)/human epidermal growth factor 2 negative (HER2-) breast cancer with an estrogen receptor 1 (ESR1) mutation. The main question the study aims to answer is: • To compare the efficacy of the combination of lasofoxifene and abemaciclib with that of fulvestrant and abemaciclib Participants will receive either receive 5 mg/d of oral lasofoxifene plus oral abemaciclib 150 mg twice a day or the combination of fulvestrant 500 mg intramuscular (IM) on Days 1, 15, and 29 and then once monthly thereafter plus oral abemaciclib 150 mg twice a day.

Study STX-478-101 is a multipart, open-label, phase 1/2 study evaluating the safety, tolerability, pharmacokinetics (PK), and preliminary antitumor activity of STX-478 in participants with advanced solid tumors with P13Ka mutations. Part 1 will evaluate STX-478 as monotherapy in participants with advanced solid tumors. Part 2 will evaluate STX-478 therapy as combination therapy with fulvestrant in participants with hormone receptor positive (HR+) breast cancer. Part 3 will evaluate STX-478 as combination therapy with fulvestrant and a CDK4/6 Inhibitor (either Ribociclib or Palbociclib) in participants with HR+ breast cancer. Each study part will include a 28-day screening period, followed by treatment with STX-478 monotherapy or combination therapy. Read Less

Phase I Study of NT-175, an autologous T cell therapy product genetically engineered to express an HLA-A\*02:01-restricted T cell receptor (TCR), targeting TP53 R175H mutant solid tumors. Read Less

Newly diagnosed post-menopausal women with clinical stage II-III, HR+HER2- breast cancer are eligible to a randomized trial, concurrently open at five US academic institutions. Patients receiving 4 months of standard neoadjuvant hormonal therapy with letrozole are randomly assigned to one of 4 arms of a trial testing focal hypo-fractionated RT alone or with immunotherapy combinations.

This study is a Phase II, multi-site, randomized, open-label clinical study to evaluate the safety, efficacy, and pharmacokinetics (PK) of BNT327 at two dose levels in combination with chemotherapeutic agents in the first- and second-line treatment of participants with locally advanced/metastatic triple-negative breast cancer (mTNBC).

Phase 1/2 study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of SNS-101, a novel anti VISTA IgG1 monoclonal antibody as monotherapy or in combination with cemiplimab in patients with advanced solid tumors. Read Less

This is an open-label, multi center study to evaluate safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of PF-07248144 and early signs of clinical efficacy of PF-07248144 as a single agent and in combination with either fulvestrant or letrozole + palbociclib or with PF-07220060 + fulvestrant Read Less

This phase II trial tests how well an imaging procedure called fludeoxyglucose F-18 (FDG) positron emission tomography/computed tomography (PET/CT) works in predicting response to standard of care chemotherapy prior to surgery in patients with HER2-positive stage IIa-IIIc breast cancer. FDG is a radioactive tracer that is given in a vein before PET/CT imaging and helps to identify areas of active cancer. PET and CT are imaging techniques that make detailed, computerized pictures of areas inside the body. The use of FDG-PET/CT may help doctors better decide if a patient needs more or less treatment before surgery in order to get the best response. This study evaluates whether FDG-PET/CT is useful in predicting a patient's response to standard of care chemotherapy. Read Less

Most physicians still use a one-size-fits-all approach to breast screening in which all women, regardless of their personal history, family history or genetics (except BRCA carriers) are recommended to have annual mammograms starting at age 40. Mammograms benefit women by detecting cancers early when they are easier to treat, but they are not perfect. Recent news stories have discussed some of the potential harms: large numbers of positive results that cause stressful recalls for additional mammograms and biopsies. With the current screening approach, half of the women who undergo annual screening for ten years will have at least one false positive biopsy. Potentially more important are cancer diagnoses for growths that might never come to clinical attention if left alone (called "overdiagnosis"). This can lead to unnecessary treatment. Even more concerning is evidence that up to 20% of breast cancers detected today may fall into the category of "overdiagnosis." This study compares annual screening with a risk-based breast cancer screening schedule, based upon each woman's personal risk of breast cancer. The investigators have designed the study to be inclusive of all, so that even women who might be nervous about being randomly assigned to receive a particular type of care (a procedure that is typical in clinical studies) will still be able to participate by choosing the type of care they receive. For participants in the risk-based screening arm, each woman will receive a personal risk assessment that includes her family and medical history, breast density measurement and tests for genes (mutations and variations) linked to the development of breast cancer. Women who have the highest personal risk of developing breast cancer will receive more frequent screening, while women with a lower personal risk would receive less frequent screening. No woman will be screened less than is recommended by the USPSTF breast cancer screening guidelines. If this study is successful, women will gain a realistic understanding of their personal risk of breast cancer as well as strategies to reduce their risk, and fewer women will suffer from the anxiety of false positive mammograms and unnecessary biopsies. The investigators believe this study has the potential to transform breast cancer screening in America. Read Less
