• •• Initiation of bisphosphonates or similar agents during the study may be allowed provided the participant completes the first cycle of treatment without any dose limiting toxicity (DLT) and the Investigator rules out tumor progression
• •11. Male or female participants of child-producing potential must agree to use adequate contraception, including double-barrier contraceptive measures, oral contraception, or avoidance of intercourse during the study and for 90 days after the last dose of study treatment
• •12. Women of childbearing potential must have a negative serum pregnancy test. "Women of childbearing potential" is defined as sexually mature women who have not undergone a hysterectomy or who have not been naturally postmenopausal for at least 12 consecutive months prior to the first dose of study treatment
• •1. Anti-cancer therapy, such as chemotherapy, immunotherapy, hormonal therapy, targeted therapy, or investigational agents within five half-lives or four weeks, whichever is shorter, prior to administration of the first dose of study treatment
• •* To be eligible for study treatment, toxicity from prior treatment(s) must recover to Grade ≤ 1, except for alopecia
• •* Concurrent systemic high-dose corticosteroids (in dosing exceeding 10 mg QD of prednisone equivalent) when used intermittently in an antiemetic regimen, for central nervous system (CNS) metastases management, or as a part of the premedication regimen are allowed
• •2. Radiation therapy within four weeks, or palliative radiation therapy within two weeks, prior to administration of the first dose of study treatment
• •* To be eligible for study treatment, radiation therapy-related toxicity must recover to Grade ≤ 1 prior to administration of the first dose of study treatment
• •* Concurrent palliative radiotherapy for local pain-control or prevention of fracture (for known bone metastases) may be allowed provided the participant completes the first cycle of treatment, does not meet criteria of progressive disease, and treated lesions will not be included in the target/non-target lesion assessment
• •3. Major surgical procedure within four weeks prior to administration of the first dose of study treatment

• •4. Unable or unwilling to swallow the complete daily dose of vevorisertib
• •5. Previous treatment with
• •* AKT inhibitors (e.g., ARQ 092, MK-2206, GSK2141795, AZD5363; prior treatment with PI3K or mammalian target of rapamycin (mTOR) inhibitor are allowed)
• •* Prior taxane therapy for the advanced, metastatic disease (for participants considered for vevorisertib +paclitaxel combination arm only)
• •6. Known prior allergic reaction to or severe intolerance of paclitaxel or fulvestrant. Intolerance is defined as a serious adverse event (AE), a grade 3 or 4 AE per Common Terminology Criteria for Adverse Events (CTCAE) v.4.03, or permanent treatment discontinuation
