histologically or cytologically confirmed; or pleural effusion with radiologically
proven pleural malignancy as diagnosed in normal clinical practice on thoracic
computed tomography in the absence of histocytological proof

3. Eastern Cooperative Oncology Group (ECOG) performance status: 0 to 2. Patients with an
ECOG performance status of 3 may be included if the Investigator determines that
removal of pleural fluid would improve their performance status to 2 or better.

4. Life expectancy of at least 8 weeks.

5. Age =18 years.

6. Body weight =45 kg and body mass index =17 kg/m2.

7. Adequate hematologic function, defined as:

1. Platelet count =100,000/µL;

2. Prothrombin time and activated partial thromboplastin time =1.5 times the upper
limit of normal (ULN);

3. Absolute neutrophil count =1,500 µL;

4. Hemoglobin =8 g/dL (transfusion and erythropoietic agents are allowed). In case
there is existence of active bleeding or other persistent condition of either
increased destruction or impaired production of erythrocytes, which may require
repeated transfusion or erythropoietic treatment, the eligibility must be
discussed with the Sponsor on a case-by-case basis prior to randomization).

8. Adequate renal function, defined as serum creatinine =2.0 times ULN and creatinine
clearance >50 mL/minute.

9. Adequate liver function, defined as:

1. Aspartate aminotransferase and alanine aminotransferase =2.0 times ULN;

without any other medical reasons) are eligible if they have negative serum pregnancy
test result 7 days before the first dose of SCB-313 and are willing to use an
effective method of birth control/contraception to prevent pregnancy until 6 months
after discontinuation of SCB-313.

Both men and women of reproductive potential must agree to use effective contraception
during the study and for 6 months after discontinuation of SCB-313.

Note: Contraceptive methods that are considered highly effective areas follows: total
abstinence, intrauterine device, double barrier method (such as condom plus diaphragm
with spermicide), contraceptive implant, hormonal contraceptives (contraceptive pills,
implants, transdermal patches, hormonal vaginal devices, or injections with prolonged

therapy within 5 half-lives prior to enrollment, radiotherapy outside the chest field
within 2 weeks, or radiotherapy inside the chest field within 12 weeks prior to
enrollment. Prior therapy with monoclonal antibody should be stopped per
Investigator's judgement making sure delayed side effects will not interfere with the
DLT evaluation period after SCB-313 therapy.

4. Acute or chronic infection (such as tuberculosis) requiring antiviral or intravenous
antibiotics within 2 weeks prior to enrollment.

5. Symptoms or signs (including laboratory tests) of clinically significant concomitant
hematologic, cardiovascular, pulmonary, hepatic, renal, pancreatic, or endocrine

angina, unstable cardiac arrhythmia requiring medication, and/or long QT syndrome or
QT/QTc interval >450 msec at Baseline.

10. Uncontrolled hypertension defined as systolic blood pressure =160 mmHg and/or
diastolic blood pressure =100 mmHg confirmed upon repeated measures (note: no more
than 3 repeated measures allowed).

11. Left ventricular ejection fraction <40% as determined by echocardiography or
multigated acquisition (MUGA) scan performed at Screening or within 90 days prior to
enrollment.

12. Major surgery (open procedures) within 4 weeks prior to enrollment.

13. Patient with ileus within 30 days prior to Screening.

14. Positive serology test for human immunodeficiency virus type 1 and/or 2, or known
history of other immunodeficiency disease.

15. Live vaccine within 2 weeks prior to enrollment.

16. Scheduled participation in another clinical study involving an investigational product
or device during the course of this study.

17. Previous treatment with a TRAIL-based therapy or death receptor 4/5 agonist therapy.

18. Known or suspected hypersensitivity to any component of SCB-313.

19. Any further condition which, in the opinion of the Investigator, may result in undue
risk of the patient by participating in the present study.

20. Untreated central nervous system metastatic disease, leptomeningeal disease, or cord
compression.
