Female patients must be either of non-childbearing potential, i.e. surgically sterilized or one year post-menopausal; or, if of childbearing potential, confirmed not pregnant at screening and must use adequate contraceptive precautions (as per investigator) during the entire treatment period of this study and for 6 months after exiting from the study.

11. Male patients with female partners of childbearing potential must be willing to use a reliable form of contraception (as per investigator), from screening until 6 months after exiting from the study.

12. Given signed and dated written informed consent and willing/able to comply with all protocol required visits/procedures

Exclusion Criteria:

1. Primary major surgery < 4 weeks prior to the planned first study treatment day.

2. Lactating or pregnant women or plans to be become pregnant.

3. Except for alopecia, any drug-related AE from any previous treatments not recovered to grade 1 or less prior to the planned first study treatment day.

4. With active systemic infections, active and clinically significant cardiac diseases, active gastrointestinal diseases, active pulmonary diseases, or medical conditions that may significantly affect adequate absorption of investigational product, eg., bad nutrition, proteinuria, etc..

5. Previous malignancy, except for basal-cell carcinoma of skin or carcinoma-in-situ of the uterine cervix, unless the tumor was treated with curative intent more than 2 years prior to study entry.

6. Known allergic to OB318 or its formulation excipients.

7. History of autoimmune disease.

8. Taking anti-coagulant or anti-platelet drugs (eg aspirin, Coumadin, ginko, clopidogrel).

9. Use of any investigational agents or non-registered product within 4 weeks of baseline.

10. Known human immunodeficiency virus (HIV) positivity.

11. With conditions, judged by the investigator, as unsuitable for the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dose limiting toxicities (DLTs) of OB318	NOTE: DLT is defined as any grade 3 or above toxicity by NCI-CTCAE version 4.03, as determined by the investigator and sponsor, to be at least possibly related in causality to the administered investigational product OB318 and will be observed during the 4 weeks of treatment for patients in the dose escalation phase.	28 days
Primary	Maximum tolerated dose (MTD) of OB318	NOTE:- MTD is defined as the prior dose level below the dose level at which 2/3 or 2/6 subjects suffer dose limiting toxicity (DLT) in the dose escalation phase	28 days
Secondary	Changes in laboratory safety tests (hematology, biochemistry, urinalysis) from baseline	Laboratory safety tests will be performed at screening, baseline, Day 14 and Day 28 for the dose escalation, and at the last follow-up visit. For the extension phase, lab tests will be done before each 28 days cycle.	up to 84 days
