          -  Life expectancy of at least 3 months.

          -  Recovery to Grade 1 or baseline of any toxicities due to prior systemic treatments,
             excluding alopecia.

          -  If a woman, be of non-child bearing potential or, for women of child-bearing potential
             (WCBP) (defined as a sexually mature woman who has not undergone surgical

             consecutive months for women ≤55 years; for women >55 years 12 consecutive months),

             of study drug.

          -  All WCBP and all sexually active male patients must agree to use adequate methods of
             birth control throughout the study. Adequate methods of contraception include use of
             oral contraceptives with an additional barrier method, double barrier methods

             partner vasectomy, and total abstinence.

          -  Ability to adhere to the study visit schedule and all protocol requirements.

        Exclusion Criteria:

          -  Prior treatment with any inhibitor of the hedgehog pathway (e.g. GDC-0449).

          -  Received any treatment for myelofibrosis within 2 weeks of study entry.

          -  Other invasive malignancies diagnosed within the last 3 years, except non-melanoma
             skin cancer and localized cured prostate and cervical cancer.

          -  Inadequate hepatic function defined by:

          -  Aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) >2.5 x upper
             limit of normal (ULN).

          -  Direct bilirubin >1.5 x ULN.

          -  Cirrhotic liver disease, ongoing alcohol abuse, or known chronic active or acute
             hepatitis.

          -  Inadequate renal function defined by serum creatinine >2 x ULN.

             requiring medication or mechanical control within the last 6 months.

          -  Presence of active infection or systemic use of antibiotics within 72 hours of
             treatment.

          -  Significant co-morbid condition or disease, which in the judgment of the Investigator,
             would place the patient at undue risk or interfere with the study.
