Inclusion Criteria

Inclusion Criteria

1. Phase 1b: Unresectable advanced or metastatic solid tumors.

2. Phase 1b expansion cohort and Phase 2: Histological confirmed diagnosis of
glioblastoma (expansion cohort and Cohort 1) or melanoma (expansion cohort and Cohort

Phase 1b expansion cohort glioblastoma subjects, Phase 2 Cohort 1:

3. No evidence of active CNS hemorrhage on baseline scans other than in those subjects
with recurrent glioblastoma who are stable Grade 1.

4. Subjects having first or second recurrence documented by magnetic resonance imaging
(MRI), following primary management with surgical resection or biopsy, radiotherapy
and up to two prior systemic treatments.

5. If subject is on corticosteroids, they must be on a stable dose for 1 week prior to
first dose of study drug.

6. Measurable disease defined as bidimensionally contrast enhancing lesions with clearly
defined margins by computerized tomography (CT) or MRI scan, with a minimal diameter
of 1 cm, and visible on two axial slices which are preferably at most 5 mm apart with
0 mm skip.

Phase 1b expansion cohort melanoma subjects, Phase 2 Cohort 2:

7. Radiographic/ photographic evidence of disease progression according to Response
Evaluation Criteria in Solid Tumors (RECIST 1.1) (Appendix 3) after no more than two
prior systemic regimens for unresectable Stage III or Stage IV disease.

8. American Joint Committee on Cancer (AJCC) unresectable Stage III or Stage IV

9. Measurable disease meeting the following criteria:

1. At least one lesion of ≥1.0 cm in the longest diameter for a non-lymph node or
≥1.5 cm in the short-axis diameter for a lymph node which is serially measurable
according to RECIST 1.1 using CT/MRI or photography. If there is only one
target lesion and it is a non-lymph node, it should have a longest diameter of
≥1.5 cm.

2. Lesions that have had external beam radiotherapy or loco-regional therapies such
as radiofrequency ablation must show evidence of progressive disease based on
RECIST 1.1 to be deemed a target lesion.

All subjects:

10. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

11. Adequately controlled BP with or without antihypertensive medications, defined as BP
≤150/90 mmHg at screening and no change in antihypertensive medications within 1 week
before the Screening Visit.

12. Adequate renal function as evidenced by serum creatinine ≤2.0 mg/dL or calculated
creatinine clearance ≥40 mL/min per the Cockcroft and Gault formula (see Appendix 5).

13. Adequate bone marrow function:

- Absolute neutrophil count ≥1500/mm3 (≥1.5 x 103/μL);

- Platelets ≥100,000/mm3 (≥100 x 109/L);

- Hemoglobin ≥9.0 g/dL.

14. Adequate blood coagulation function, as evidenced by an International Normalized
Ratio (INR) ≤1.5.

15. Adequate liver function:

- Bilirubin ≤1.5 x the upper limit of normal (ULN) except for unconjugated
hyperbilirubinemia of Gilbert's syndrome;

- ALP, ALT, and AST ≤3 x ULN (≤5 x ULN if subject has liver metastases).

16. Males or females age ≥18 years at the time of informed consent.

17. All females must have a negative serum or urine pregnancy test (minimum sensitivity
25 IU/L or equivalent units of beta-human chorionic gonadotropin [β-hCG] at the
Screening and Baseline Visit (a separate Baseline assessment is not required if a
negative Screening pregnancy test was obtained within 72 hours before the first dose
of study drug). Females of child-bearing potential, if not practising total
abstinence or having a vasectomized partner with confirmed azoospermia, must agree to
use two highly effective methods of contraception: e.g., 1) an intrauterine device
(IUD) or intrauterine system (IUS); 2) a barrier method such as a condom or occlusive
cup (diaphragm or cervical/vault caps) + spermicide (foam, gel, cream, etc.); 3)
oral, injected, or implanted hormonal contraceptives throughout the entire study
period and for 30 days after study drug discontinuation. Use of a double-barrier
method (i.e., use at the same time of a condom + occlusive cup [diaphragm or
cervical/vault caps] + spermicide [foam, gel, cream, etc.]) is accepted as two highly
effective methods of contraception. The only subjects who will be exempt from this
requirement are postmenopausal women (defined as women who have been amenorrheic for
at least 12 consecutive months, in the appropriate age group, without other known or
suspected primary cause) or subjects who have been sterilized surgically or who are
otherwise proven sterile (i.e., bilateral tubal ligation with surgery at least 1
month prior to dosing, total hysterectomy, or bilateral oophorectomy with surgery at
least 1 month prior to dosing). All women who are of reproductive potential and who
are using hormonal contraceptives must have been on a stable dose of the same
hormonal contraceptive product for at least 4 weeks prior to dosing and must continue
to use the same contraceptive during the study and for 30 days after study drug

18. Male subjects who are partners of women of childbearing potential must use a condom +
spermicide and their female partners, if of childbearing potential, must use a highly
effective method of contraception (see methods described in Inclusion Criterion #18)
beginning at least 1 menstrual cycle prior to starting study drug, throughout the
entire study period, and for 30 days after the last dose of study drug, unless the
male subjects are totally abstinent sexually or have undergone a successful vasectomy
with confirmed azoospermia or unless the female partners have been sterilized
surgically or are otherwise proven sterile (see Inclusion Criterion #18).

19. Voluntary agreement to provide written informed consent and the willingness and
ability to comply with all aspects of the protocol.
