About this trial

This is an interventional treatment trial for Breast Cancer

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria: Men or women at least 18 years of age with histologically or cytologically confirmed adenocarcinoma of the breast with unresectable or metastatic disease. Most recent tumor biopsy or surgical resection specimen must be either estrogen-receptor (ER) positive, progesterone receptors (PgR) positive, or both, as defined by immunohistochemistry (IHC) ≥1% (as per the American Society of Clinical Oncology (ASCO)-College of American Pathologists (CAP) guidelines). HER2-low breast cancer defined as IHC 2+/ISH- or IHC 1+ (ISH- or untested). (as per the ASCO-CAP guidelines). Postmenopausal status or receiving ovarian ablation with a GnRH agonist such as goserelin. Postmenopausal status is defined by any one of the following criteria: Prior bilateral oophorectomy. Age ≥60 years. Age <60 and amenorrhea for 12 or more months (in the absence of chemotherapy, tamoxifen, toremifen, or ovarian suppression) and FSH, LH, and estradiol in the postmenopausal range per local normal If the patient does not meet criteria for postmenopausal status but is receiving ovarian ablation therapy with a gonadotropin-releasing hormone (GnRH) agonist such as goserelin, the patient is eligible for this study, provided that the GnRH agonist is started at least 2 weeks prior to C1D1 of anti-estrogen therapy. Patient must have either measurable disease by RECIST 1.1 or only bone lesions in absence of measurable disease. Eastern Cooperative Group (ECOG) performance status of 0 or 1. Previously treated on CDK 4/6 inhibitor(palbociclib, abemaciclib or ribociclib) with AI for at least 6 months Adequate bone marrow and organ function. Exclusion Criteria: Patient with symptomatic visceral disease or any disease burden. Patient has received more than one line of chemotherapy for advanced disease. Previous treatment with Dalpiciclib /Pyrotinib /ADCe for advanced disease. Progressed on more than one CDK 4/6 inhibitor Patients with persistent symptoms and unstable brain metastases; Any condition that makes the patient ineligible for endocrine therapy per the investigator's best judgment

Arms of the Study

Arm 1

Arm Label

Dalpiciclib, Fulvestrant With Pyrotinib

Arm Description

Pyrotinib 320mg/day Dalpiciclib 125 mg/day Fulvestrant 500mg

Outcomes

Primary Outcome Measures

Progression-Free Survival (PFS) as Assessed by the Investigator
Progression free survival (PFS) is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first.

Secondary Outcome Measures

Overall Response Rate (ORR)
Evaluation of disease will be made according to RECIST criteria (version 1.1) in patients with measurable disease. As this study will enroll patients with measureable and un-measurable disease as defined by RECIST v1.1, ORR will only be assessed in evaluable patients. Response rates will be estimated as the proportion of enrolled patients who achieve complete or partial response rate.
Clinical Benefit Rate (CBR)
Clinical Benefit Rate (CBR) is defined as the percentage of participants with a complete response (CR) or partial response (PR) or with stable disease (SD) as per Response Evaluation Criteria in Solid Tumors (RECIST) V1.1 or Non-Complete Response or Non-Progressive Disease (NCRNPD) during first 24 weeks of first dose. CR=disappearance of all non-nodal target lesions, PR=at least a 30% decrease in the sum of diameter of all target lesions, SD=neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for progressive disease (PD), PD=at least a 20% increase in the sum of diameter of all target lesions.
Overall Survival (OS)
Overall survival is the time from date of first treatment to the date of death due to any cause. If a patient is not known to have died, survival will be censored at the last date of contact.
Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs; All Causalities)
An AE is any untoward medical occurrence in a clinical investigation patient administered a product or medical device; the event need not necessarily have a causal relationship with the treatment or usage. An SAE is any untoward medical occurrence at any dose that results in death; is life-threatening; requires hospitalization; results in persistent or significant disability or in congenital anomaly/birth defect. Severity will be graded by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), Version 5.0.

5. Study Description

Brief Summary
The purpose of this study is to determine if the triplet combination of dalpiciclib, fulvestrant, and pyrotinib is safe and effective in the treatment of hormone receptor-positive, HER2-low locally advanced/metastatic breast cancer following treatment with an aromatase inhibitor plus a CDK4/6 inhibitor (palbociclib abemaciclib or ribociclib). The study will employ a Bayesian Optimal Phase II (BOP2) design which explicitly controls the type I error rate, thereby bridging the gap between Bayesian designs and frequentist designs, and has favorable operating characteristics with higher power and lower risk of incorrectly terminating the trial than some existing Bayesian phase II designs.
