21 Clinical Trials for Various Conditions
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 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 other agents
This is an open label, randomized, multicenter study evaluating the activity of lasofoxifene relative to fulvestrant for the treatment of pre- and postmenopausal women with locally advanced or metastatic ER+/HER2- breast cancer with an acquired ESR1 mutation and who have disease progression on an aromatase inhibitor (AI) in combination with a cyclin dependent kinase (CDK) 4/6 inhibitor. The primary objective is to evaluate the progression free survival (PFS) of 5 mg lasofoxifene relative to fulvestrant for the treatment of pre- and postmenopausal women with 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 secondary objectives are to evaluate: 1. Clinical benefit rate (CBR) and Objective Response Rate (ORR) 2. Duration of response 3. Time to response 4. Overall Survival (OS) 5. Pharmacokinetics of lasofoxifene 6. Quality of life (QoL): Quality of Life (QoL): vaginal assessment scale (VAS) and vulvar assessment scale (VuAS) questionnaires 7. Safety of lasofoxifene 8. Response to various ESR1 mutation (Y537S, Y537C, D538G, E380Q, S463P, V534E, P535H, L536H, L536P, L536R, L536Q, or Y537N).
The purpose of this study was to assess the efficacy and safety of first-line treatment with everolimus plus letrozole in postmenopausal women with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2 negative (HER2-) locally advanced or metastatic breast cancer. Moreover, the study also aimed to investigate the efficacy and safety of second line treatment with everolumus plus examestane in participants whose disease progressed during everolimus plus letrozole therapy.
This clinical trial is evaluating a drug called AC699 in participants with estrogen receptor positive/human epidermal growth factor 2 negative (ER+/HER2-) locally advanced or metastatic breast cancer. The main goals of this study are to: * Identify the recommended dose of AC699 that can be given safely to participants * Evaluate the safety profile of AC699 * Evaluate the pharmacokinetics of AC699 * Evaluate the effectiveness of AC699
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.
This is a Phase 1/2 dose escalation and cohort expansion study and will assess the safety, tolerability and anti-tumor activity of ARV-471 alone and in combination with palbociclib (IBRANCE®) in patients with estrogen receptor positive/human epidermal growth factor receptor 2 negative (ER+/HER2-) locally advanced or metastatic breast cancer, who have received prior hormonal therapy and chemotherapy in the locally advanced/metastatic setting.
This is a phase I/II, open-label, multicenter study of AUY922 administered intravenously in patients with advanced solid malignancies to determine the maximum tolerated dose. Phase II expansion arms will investigate efficacy in patients with either HER2 positive or ER positive locally advanced or metastatic breast cancer. Additional patients with advanced solid malignancies will also be investigated in a separate expansion arm. Safety, pharmacokinetics and pharmacodynamics will be assessed.
This Phase III, randomized, open-label, multicenter study will evaluate the efficacy and safety of giredestrant plus everolimus compared with the physician's choice of endocrine therapy plus everolimus in participants with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer who have had previous treatment with cyclin-dependent kinase 4/6 inhibitors (CDK4/6is) and endocrine therapy, either in the locally advanced/metastatic or the adjuvant setting.
The purpose of this study is to perform an in depth analysis of changes in the tumor immune microenvironment in patients undergoing treatment with standard of care endocrine therapy and abemaciclib in the advanced setting via singe cell RNA sequencing. The investigators will also correlate changes in serum estrogen levels to changes in tumor and peripheral immune cell repertoire and function (including regulatory T cell populations, B cells, myeloid-derived suppressor cell populations, T cell activation and T cell exhaustion).This study has two cohorts with 15 patients in each cohort.

The purpose of this study is to determine the safety and efficacy of PF-07220060 with letrozole compared to approved treatments (ie, palbociclib, ribociclib or abemaciclib with letrozole) in people with breast cancer: * HR-positive (breast cancer cells that need estrogen or progesterone to grow) * HER2-negative (cells that have a small amount or none of a protein called HER2 on their surface); * locally advanced (that has spread from where it started to nearby tissue or lymph nodes) or metastatic disease (the spread of cancer to other places in the body) * who have not received any prior systemic anti-cancer treatment for advanced/metastatic disease. Approximately half of the participants will receive PF-07220060 plus letrozole while the other half of participants will receive the investigator's choice of treatment plus letrozole. The study team will monitor how each participant is doing with the study treatment during regular visits at the study clinic.
