             than SSAs for symptoms).

          2. History of allergic reactions to compounds of similar chemical or biologic composition
             to ABI-009.

          3. Known active uncontrolled or symptomatic central nervous system (CNS) metastases. A
             patient with controlled and asymptomatic CNS metastases may participate in this study.
             As such, the patient must have completed any prior treatment for CNS metastases ?28
             days (including radiotherapy and/or surgery) prior to start of treatment in this study
             and should not be receiving chronic corticosteroid therapy for the CNS metastases.

          4. Active gastrointestinal bleeding.

          5. Uncontrolled serious medical or psychiatric illness. Patients with a "currently

             the cervix, resected incidental prostate cancer (staged pathological tumor-2 (pT2)
             with Gleason Score ≤6 and postoperative prostate-specific antigen (PSA) <0.5 ng/mL),
             or other adequately treated carcinoma-in-situ are ineligible. Patients are not

             the first dose of ABI-009. Additionally, use of any known CYP3A4 substrates with
             narrow therapeutic window (such as fentanyl, alfentanil, astemizole, cisapride,
             dihydroergotamine, pimozide, quinidine, terfanide) within the 14 days prior to
