Breast Cancer Clinical Trials in Tucson, AZ

This study will test the safety, including side effects, and determine the characteristics of a drug called Rina-S in participants with solid tumors. Participants will have solid tumor cancer that has spread through the body (metastatic) or cannot be removed with surgery (unresectable). Read Less

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.

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 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.

This open-label research study is studying (Z)-endoxifen as a possible treatment for pre-menopausal women with ER+/HER2- breast cancer. (Z)-endoxifen belongs to a group of drugs called selective estrogen receptor modulators or "SERM", which help block estrogen from attaching to cancer cells. This study has two parts: a pharmacokinetic part and a treatment part. The PK part (how the body processes the drug) will enroll about 18 participants. All participants will take (Z)-endoxifen capsules daily. Twelve participants will be randomly assigned (50/50 chance) to take (Z)-endoxifen alone or (Z)-endoxifen with a monthly injection of goserelin a drug that temporarily stops the ovaries from making estrogen. This part will help determine the best dose of (Z)-endoxifen by measuring the drug levels in the blood and how long the body takes to remove it. The treatment part has two parts: * Part 2a will enroll 162 participants whose tumors have a high level of cell proliferation as indicated by the presence of a biomarker called Ki-67 (greater than 10%). Participants will be randomly assigned to one of two groups (50/50 chance): 1. a group receiving (Z)-endoxifen daily with a monthly injection of goserelin 2. a group receiving the current standard treatment of exemestane (an aromatase inhibitor that lowers estrogen) with a monthly injection of goserelin. * The Part 2b will enroll about 30 participants whose tumors have low Ki-67 levels (10% or less). These participants will take daily (Z)-endoxifen alone without goserelin. A key goal of the study is to see if (Z)-endoxifen can slow down or stop tumor growth as measured by a reduction in Ki-67 levels. Tumor tissue samples will be taken by breast biopsy after about 4 weeks of treatment to check levels of this biomarker. If the tumor shows signs of response, participants can continue treatment for up to 24 weeks or until they have surgery. Study participation is up to 6 months (24 weeks of treatment) followed by surgery and a one-month follow up visit. Read Less

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.

This clinical trial is studying solid tumor cancers. A solid tumor is one that starts in part of your body like your lungs or liver instead of your blood. Once they've grown bigger in one spot or spread to other parts of the body, they're harder to treat. This is called advanced or metastatic cancer. Participants in this study must have breast cancer or gastric cancer. Participants must have tumors that have HER2 on them. This allows the cancer to grow more quickly or spread faster. There are few treatment options for patients with advanced or metastatic solid tumors that express HER2. This clinical trial uses an experimental drug called disitamab vedotin (DV). Disitamab vedotin is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial uses a drug called tucatinib, which has been approved to treat cancer in the United States and some other countries. This drug is sold under the brand name TUKYSA®. This study will test how safe and how well DV, with or without tucatinib, is for participants with solid tumors. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease. Read Less

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).

This is an open-label, FIH study designed to evaluate the maximum tolerated dose, recommended Phase 2 dose, safety, tolerability, PK, pharmacodynamics, and preliminary antineoplastic activity of RLY-2608, in advanced solid tumor patients with a Phosphatidylinositol-4,5-bisphosphate-3 kinase, catalytic subunit alpha (PIK3CA) mutation in blood and/or tumor per local assessment. The study will evaluate RLY-2608 as a single agent for patients with unresectable or metastatic solid tumors. It will also evaluate RLY-2608 in combination RLY-2608 + fulvestrant and in triple combination RLY-2608 + fulvestrant + CDK4/6 inhibitor (palbociclib or ribociclib) or CDK4 inhibitor (PF-07220060) for patients with HR+ HER2- locally advanced or metastatic breast cancer or endometrial cancer (palbociclib or ribociclib Part 1). The RLY-2608 single agent arm, RLY-2608 + fulvestrant combination arm, and triple combination arms will have 2 parts: a dose escalation (Part 1) and a dose expansion (Part 2). Read Less

A randomized, Phase II trial of circulating tumor DNA-guided second line Adjuvant therapy for high Residual risk, Estrogen Receptor positive, HER-2 negative breast cancer (DARE) Read Less

A prospective, multicenter, observational study to evaluate the correlation of Molecular Residual Disease (MRD) detection using circulating tumor DNA guided test to pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) in stage I-III triple negative breast cancer (TNBC). Results from this study aim to improve MRD detection and disease outcomes for future patients. Read Less

The purpose of this study is to further advance the ability to practice personalized medicine by learning which new drug agents are most effective with which types of breast cancer tumors and by learning more about which early indicators of response (tumor analysis prior to surgery via magnetic resonance imaging (MRI) images along with tissue and blood samples) are predictors of treatment success.
