Eligibility Criteria

• Age: 18 Years+
• Sex: female
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Participants volunteered to participate in this study and signed an informed consent form.
• Female, aged ≥ 18 years.
• ECOG PS score:0-2.
• Expected survival time ≥ 3 months.
• Histologically or cytologically confirmed estrogen receptor positive and/or progesterone receptor positive, HER2-negative loco-regional recurrent or metastatic disease not amenable to resection or radiation therapy with curative intent.
• Prior anti-tumor setting: ① No prior chemotherapy for recurrent or metastatic breast cancer; ② Disease recurrence and/or metastasis during or after palbociclib-based regimen in the (neo)adjutant setting or disease progression during or after palbociclib-based regimen for at least 6 months in the metastatic setting; ③ No more than 3 lines of prior endocrine therapy for recurrent or metastatic breast cancer and meet one of the following requirements: relapse while after the first 2 years of adjuvant endocrine therapy, or disease progression after the first 6 months of latest endocrine therapy for advance or metastatic breast cancer, while on endocrine therapy;
• At least one extracranial measurable lesion defined according to RECIST V1.1 criteria or only bone lesion;
• The functions of vital organs meet the requirements;
• Participants recovered from any AE associated with prior tumor therapy prior to initial administration of the study drug (grade ≤1);

You may not qualify if:

• Prior treatment with histone deacetylase inhibitors (HDACi);
• Previously treated with CDK4/6 inhibitors other than palbociclib;
• Leptomeningeal metastasis confirmed by MRI or lumbar puncture;
• Radiographically confirmed central nervous system metastasis; the following conditions were excluded: ① asymptomatic brain metastases not requiring immediate radiotherapy or surgery; ② previously received local therapy (radiotherapy or surgery) for brain metastasis, stable for at least 4 weeks with imaging confirmation without symptomatic treatment (including glucocorticoid, mannitol, bevacizumab, etc.) for more than 2 weeks and clinical symptoms;
• Participants with visceral crises (e.g., lymphangitis carcinoma, bone marrow replacement, leptomeningeal metastasis, diffuse liver metastasis with abnormal liver functions), rapid disease progression, and patients not suitable for endocrine therapy;
• Participants with ascites, pleural effusion and pericardial effusion with clinical symptoms at baseline, requiring drainage within 4 weeks before the first medication;
• Inability to swallow, intestinal obstruction or other factors affecting drug taking and absorption;
• Systematic treatment such as chemotherapy, targeted therapy or other investigational drugs within 4 weeks prior to the start of treatment; endocrine therapy within 2 weeks prior to the start of treatment;
• Participant was diagnosed with any other malignant tumor in the past 5 years prior to the study, except for radically-treated non-melanoma skin cancer, basal cell or squamous cell skin cancer or cervical carcinoma in situ and thyroid papillary carcinoma.
• The participant has undergone major surgical procedures or significant trauma within 4 weeks prior to the start of treatment, or is expected to undergo major surgical treatment;
• Known history of allergy to the drug components of this regimen;
• Infected with active HBV and HCV; participants with stabilized hepatitis B (HBV-DNA lower than 500 IU/mL or copy number \<1000 copies/ mL) and cured hepatitis C (negative for HCV RNA) were excluded;
• Have a history of immunodeficiency disease, including HIV positive, or other acquired or congenital immunodeficiency disease, or have a history of organ transplantation;
• Positive baseline pregnancy test; Or participants of reproductive age who were unwilling to use effective contraception during study participation and for at least 3 months after the last dose;
• According to the judgment of the researcher, there are serious concomitant diseases (such as severe hypertension, diabetes, thyroid disease, active infection, etc.) that endanger the patient's safety or affect the patient's completion of the study;
