6. Resolution of all acute adverse events resulting from prior cancer therapies to
National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE)
Grade ≤ 1 or baseline (except alopecia or neuropathy)

7. Adequate organ function

8. Willingness and ability to consent for self to participate in study

9. Willingness and ability to comply with scheduled visits, treatment plan, laboratory
tests, and other study procedures

Exclusion Criteria:

1. Autoimmune disease requiring treatment within the past twelve months

2. Condition requiring systemic treatment with either corticosteroids or other
immunosuppressive medications within 14 days prior to study treatment

3. History of or active interstitial lung disease

4. Prior T-cell therapy

5. Current treatment on another therapeutic clinical trial

6. Receipt of systemic anticancer therapy, including investigational agents, within 28
days prior to study treatment

7. Major surgical procedure or significant traumatic injury within 4 weeks prior to study
treatment, and must have fully recovered from any such procedure; and no date of
surgery (if applicable) or anticipated need for a major surgical procedure planned
within the next 6 months

8. Chest radiotherapy ≤ 28 days, wide field radiotherapy ≤ 28 days (defined as > 50% of
volume of pelvic bones or equivalent), or limited field radiation for palliation ≤ 14
days prior to study treatment - such patients must have recovered adequately from any
side effects of such therapy.

9. Hypertension defined as blood pressure (BP) systolic > 150 or diastolic > 90 mm Hg

10. Ascites or pericardial effusion that required intervention within 3 months prior to
study treatment.

11. Brain involvement with cancer, spinal cord compression, or carcinomatous meningitis,
or new evidence of brain or leptomeningeal disease, unless the lesion(s) have been
radiated or resected, are considered fully treated and inactive, are asymptomatic, and
no steroids have been administered for CNS disease over the 7 days prior to study
treatment

12. Angina, myocardial infarction (MI), symptomatic congestive heart failure,
cerebrovascular accident, transient ischemic attack TIA), arterial embolism, pulmonary
embolism, percutaneous transluminal coronary angioplasty (PTCA), or coronary artery
bypass grafting (CABG) within 6 months prior to study treatment

13. Thrombolytic use (except to maintain IV catheters) within 10 days prior study
treatment

14. Known active viral or nonviral hepatitis or cirrhosis, except patients with Hepatitis
C infection and undetectable virus following treatment are eligible.

15. Any active infection requiring systemic treatment

16. History of hemorrhage or hemoptysis (> ½ teaspoon bright red blood) within 3 months
prior to study treatment

17. Known human immunodeficiency virus (HIV) unless CD4+ T cell count > 350 cells/μL with
an undetectable viral load.

18. Pregnancy or breastfeeding - Female patients must be surgically sterile (i.e., ≥ 6
weeks following surgical bilateral oophorectomy with or without hysterectomy or tubal
ligation) or be postmenopausal, or must agree to use effective contraception during
the study and for 5 months following last dose of TJ004309. All female patients of
reproductive potential must have a negative pregnancy test (serum or urine) within 7
days prior to study treatment. Male patients must be surgically sterile or must agree
to use effective contraception during the study and for 6 months following last dose
of TJ004309.

19. Other severe acute or chronic medical or psychiatric condition or laboratory
abnormality that may increase the risk associated with study participation or may
interfere with the interpretation of study results and, in the judgment of the
Investigator, would make the patient inappropriate for this study
