Eligibility |
Inclusion Criteria: 1. be =18 years of age; 2. have a diagnosis of metastatic ER+ breast cancer in patients who received and progressed on at least two lines of endocrine therapy, with one that included a CDK4/CDK6 inhibitor (e.g., palbociclib or ribociclib); 3. have metastatic disease evaluable on imaging studies; 4. have a histologically confirmed diagnosis of ER+ breast cancer; 5. have an Eastern Cooperative Oncology Group (ECOG) performance status of =1 (Appendix II); 6. have adequate hepatic function, defined as having a serum total bilirubin concentration =1.5mg/d, or =2 x the upper limit of normal (ULN) if associated with hepatobiliary metastases or Gilbert syndrome, and having serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentrations =2.5 × ULN, or =5 x ULN for patients with known hepatic metastases; 7. have adequate renal function, defined as having a serum creatinine =1.5 × ULN and a creatinine clearance =40mL/min (estimated using the Cockcroft-Gault formula); 8. have adequate hematologic function, defined as having a hemoglobin =8g/dL, an absolute neutrophil count (ANC) =1.0 × 109/L, and platelet count =75.0 x 109/L; 9. be willing and able to comply with study visits and procedures; 10. have read, understood and signed the informed consent form (ICF) approved by the Institutional Review Board (IRB); 11. if a woman of childbearing potential (WOCP), not be pregnant (confirmed by a negative serum pregnancy test within 14 days of study entry and re-confirmed by a urine pregnancy test on the morning of Study Day 1, prior to the start of study treatment) and/or not be breast-feeding; [Note: Women who are postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy) are not considered to be a WOCP.] 12. If a WOCP, agree to use during the study and for at least one month after the last dose of study drug a medically acceptable method of birth control [such as an oral, implantable, injectable, or transdermal hormonal contraceptive, an intrauterine device (IUD), a double barrier method (condoms, sponge, diaphragm, or vaginal ring with spermicidal jellies or cream), or total abstinence.]; 13. if male (and whether or not surgically or medically sterile), agree to use during the study and for at least one month after the last dose of study drug a double barrier method of birth control (in addition to any other birth control method practiced by his partner) while engaging in sexual intercourse with a partner who is pregnant, possibly pregnant or able to become pregnant. Exclusion Criteria: 1. have received chemotherapy, hormonal therapy, biologic therapy, immunotherapy or radiation therapy within 14 days prior to the planned start of study treatment. 2. have inadequate recovery* from adverse events resulting from previously-administered anti-cancer therapies; [*Note: Unless more specifically defined in Inclusion Criteria 6, 7 and 8 above, adequate recovery is defined as improvement to = Grade 2 for any other hematologic toxicity and for peripheral neuropathy, and improvement to = Grade 1 for any other non-hematologic toxicity.] 3. have a history of venous thromboembolism, including deep vein thrombosis, pulmonary embolism or retinal vein thrombosis, unless currently on anticoagulant therapy; 4. have impending visceral crisis that requires chemotherapy; 5. have known uncontrolled or symptomatic CNS metastases; 6. have any clinically significant infection, defined as any acute viral, bacterial, or fungal infection that requires systemic treatment or have received any anti-infective treatment within 7 days prior to the screening visit; 7. have any other severe, uncontrolled medical condition, including unstable congestive heart failure (Stage III-IV of the New York Heart Association Functional Classification (Appendix III)) 8. have a known or suspected allergy to the study drug or any study drug component; 9. have any other medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation, that may interfere with the interpretation of study results or that otherwise would, in the opinion of the Investigator, make study participation inappropriate; 10. have any non-healing wound, fracture, or ulcer within 28 days prior to the planned start of study treatment; 11. have received any other investigational drug within 28 days (or 5 half-lives, if longer) prior to the start of study screening. |

Primary | MTD | The primary objective of this study is to determine the maximum tolerated dose (MTD) of TTC-352 for the treatment of metastatic ER+ breast cancer progressing after endocrine therapy | 24 months | |
Secondary | Best response to treatment | Determine patient best response to treatment (complete response, partial response, stable disease or disease progression) after at least two 28-day cycles of treatment with TTC 352. | 24 months | |
Secondary | PFS | Determine durations of progression-free survival after at least two 28-day cycles of treatment with TTC 352 | 24 months | |
Secondary | Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 | Treatment-related adverse events as assessed by CTCAE v4.0 will be collected in presented in tabular form at the end of study. | 24 months | |
Secondary | Maximum Plasma Concentration (Cmax) | Blood samples will be collected at the following Cycle 1 time points: Day 1: prior to dosing and at Hours 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12 and 24 after dosing (just before dosing on Day 2). Day 28: prior to dosing and at Hours 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12, 24 and 28 after dosing. TTC-352 blood levels will be measured at above time points and Cmax will be calculated. |
24 months | |
Secondary | Half life | Blood samples will be collected at the following Cycle 1 time points: Day 1: prior to dosing and at Hours 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 12 and 24 after dosing (just before dosing on Day 2).
