入选标准
- •Signed informed consent prior to any study specific procedures.
- •. Patients must have a life expectancy ≥ 16 weeks.
- •ECOG performance status of 0 to 1 within 28 days of enrollment.
- •Documented markers such as mismatch repair (MMR) status, hormone receptors (estrogen and progesterone receptors) and p53 status according to molecular or immunohistochemical classification of EC.
- •Patient must be able to take oral medications.
- •Patients must have normal organ and bone marrow function measured as defined below: a. Haemoglobin ≥ 9.0 g/dL with no blood transfusion in the past 28 days b. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L c. Aspartate aminotransferase (AST) (Serum Glutamic Oxaloacetic Transaminase (SGOT)) / Alanine aminotransferase (ALT) (Serum Glutamic Pyruvate Transaminase (SGPT)) ≤ 2.5 x institutional upper limit of normal unless liver metastases are present in which case they must be ≤ 5x ULN d. Total bilirubin < 1.5 x upper limit of normal (ULN) (< 3 x ULN if Gilbert’s disease). e. Patients must have creatinine clearance estimated of ≥ 60mL/min using the Cockcroft-Gault equation or based on a 24 hour urine test: Estimated creatinine clearance = (140-age [years]) x weight (kg)(x F)a serum creatinine (mg/dL) x 72 (a where F=0.85 for females). f. INR or PT aPTT/PTT ≤1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants (INR between 2.5 and 3.5 x ULN is permitted). g. Fasting blood glucose ≤140 mg/dL and HbA1c <6.5%. Specifically, patients with Type 2 diabetes are eligible to enroll provided they meet the above criteria for fasting blood glucose and HbA1C and are on a stable dose of no more than one oral antidiabetic agent for ≥2 weeks prior to initiation of study treatment. The administration of insulin should not be counted as a 2nd agent.
- •Patients are eligible to participate only if are not not pregnant or breastfeeding, and at least one of the following conditions applies. a. Is not a Women of Childbearing Potential (WOCBP) A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state ( 12 continuous months of amenorrhea with no identified cause other than menopause), and is not permanently infertile due to surgery (i.e., removal of ovaries, fallopian tubes, and/or uterus) or another cause as determined by the investigator (e.g., Müllerian agenesis). b. Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1% per year), with low user dependency, or be abstinent from heterosexual intercourse as their preferred and usual lifestyle during the intervention period and for at least 2 weeks after the final dose of inavolisib. The investigator should evaluate the potential for contraceptive method failure (ie, noncompliance, recently initiated) in relationship to the first dose of study intervention. c. A WOCBP must have a negative highly sensitive pregnancy test (urine or serum) within 24 hours before the first dose of study intervention. Note If a urine test cannot be confirmed as negative (eg, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive.
- •Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures.
- •Female, age ≥ 18 years at time of signing informed consent.
- •Patients with histologically or cytologically confirmed diagnosis of advanced, recurrent or metastatic endometrial carcinoma (endometrioid, serous, clear cell, carcinosarcoma or mixed histology).
- •Biomarker eligibility: valid results from testing of tumor tissue documenting PIK3CA mutations listed below (a-m); however, activating PIK3CA mutations not listed may also be included, capped at 20% of the study population.
- •Data from the reports indicating the pertinent PIK3CA mutation as well as the status of PTEN gene, and relative variant of allelic frequency (VAF) for each altered gene must be available upon enrollment. Local test results reported from tumor tissue should be from the patient’s locally advanced or metastatic disease state whenever possible. Specifically, the detection of PIK3CAm combined with knowledge of PTEN molecular status is mandatory for the screening.
- •All patients are required to submit a paraffin embedded block from the primary surgery/biopsy (chemotherapy - naive patients) and a freshly collected pre treatment blood samples. A quality control analysis of samples will be performed by the Sponsor, before patient’s enrollment. Only patients with adequate tumor sample will be enrolled.
- •Patients must have progressed after or during a platinum based-chemotherapy with or without immunotherapy in any setting. Specifically, patients receiving previous platinum-based chemotherapy in the neoadjuvant or adjuvant setting must have progressed within 6 months of last platinum therapy.
- •Patients must have received no more than 4 previous systemic therapy for endometrial cancer. Specifically, endocrine therapies, maintenance with PARP inhibitor or selinexor are not counted as a systemic line of therapy
- •At least 1 measurable target lesion according to RECIST 1.1
排除标准
- •Endometrial tumors with the following histologies: squamous carcinomas, sarcomas.
- •Known untreated CNS metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable, (i.e. without evidence of progression) for at least 4 weeks by repeat imaging (Note: The repeat imaging should be performed during study 28 Screening.), clinically stable, and without requirement of steroid treatment for at least 14 days before the first dose of study intervention.
- •Other malignancy unless curatively treated with no evidence of disease for ≥5 years except: adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS).
