             combination and paclitaxel (ASP).

          -  Dose expansion cohort only: Histological or cytological confirmation of advanced
             unresectable solid tumors for which no standard therapy is available in patients with
             a known BRCA germline mutation or those with metastatic triple negative breast cancer
             without known BRCA mutation (see inclusion criteria one for definition of triple
             negative breast cancer).. For the paclitaxel cohorts, any solid tumors with potential
             benefit from this combination and paclitaxel.

             or implantable hormonal contraceptive; tubal ligation; intra-uterine device; barrier
             contraceptive with spermicide; or vasectomized partner) for a minimum of 4 weeks

        FCBP is defined as a sexually mature woman who:

          -  Has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral
             oophorectomy (the surgical removal of both ovaries) or,

          -  Male subjects with female partner of childbearing potential must agree to the use of a
             physician-approved contraceptive method throughout the course of the study and for a
             minimum of 4 weeks following the discontinuation of study treatment.

             or 4 weeks, whichever is shorter, prior to starting study treatment

          -  Patients must have recovered from side effects from prior cancer-directed therapy to
             grade 1 or less (unless deemed not clinically significant by study investigator).
