results obtained within 14 days prior to the randomization.1) Absolute lymphocyte
count (ALC) =1×109/L. 2) Absolute neutrophil count (ANC) = 1.5×109/L. 3) Platelet
count = 100×109/L (without transfusion within 14 days prior to Cycle 1, Day 1). 4)
Hemoglobin = 9 g/dL Patients may be transfused or may receive erythropoietic treatment
as per local standard of care. 5) Total bilirubin = 1.5 × the upper limit of normal
(ULN). 6) AST and ALT = 3 × ULN. 7) Alkaline phosphatase = 2.5 × ULN (For subject with
proven liver or bone metastasis, alkaline phosphatase = 5 × ULN is allowed). 8) Serum
albumin = 2.5 g/dL. 9) Serum creatinine = 1.5 mg/dL. 10) Prothrombin time (PT) and
activated partial thromboplastin time (aPTT) = 1.5 × ULN. This applies only to
patients who are not receiving therapeutic anticoagulation. Patients receiving
therapeutic anticoagulation should be on a stable dose
6. Karnofsky score = 60
7. Life expectancy > 12 weeks
8. For women of childbearing potential*: agreement to remain abstinent (refrain from
heterosexual intercourse) or use contraceptive methods that result in a failure rate
of < 1% per year from the date of informed consent to at least 3 months after the last
dose of study drugs. For men: agreement to remain abstinent (refrain from heterosexual
intercourse) or use contraceptive measures, and agreement to refrain from donating
sperm, as defined below: With female partners of childbearing potential or pregnant
female partners, men must remain abstinent or use a condom during the treatment period
and for at least 3 months after the last dose of study treatment (TJ107) and 6 months
after the last dose of temozolomide to avoid exposing the embryo. Men must refrain
from donating sperm during this same period. The reliability of sexual abstinence
should be evaluated in relation to the duration of the clinical trial and the
preferred and usual lifestyle of the patient. Periodic abstinence and withdrawal are
not acceptable methods of contraception.
- A woman is of childbearing potential if she is postmenarcheal, has not reached a
postmenopausal state (= 12 continuous months of amenorrhea with no identified
cause other than menopause), and has not undergone surgical sterilization
(removal of ovaries and/or uterus).
- Examples of contraceptive methods with a failure rate of < 1% per year include
bilateral tubal ligation, male sterilization, and established proper use of
hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine
devices, and copper intrauterine devices.
- Hormonal contraceptive methods must be supplemented by a barrier method plus
spermicide.
- The reliability of sexual abstinence should be evaluated in relation to the
duration of the clinical trial and the preferred and usual lifestyle of the
patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or
post-ovulation methods) and withdrawal are not acceptable methods of
contraception
Exclusion Criteria:
1. Subjects receiving 21 days hypofractionated radiotherapy due to clinical condition
2. Multifocal glioma (=3 lesions)

before randomization.
6. Pregnancy, lactation, or breastfeeding (with lactation or breastfeeding required
during the study period)
*Serum pregnancy test for women of childbearing potential (including women who have
had a tubal ligation) must be performed and documented as negative within 14 days
prior to randomization
7. Significant cardiovascular disease, such as New York Heart Association cardiac disease
(Class II or greater), myocardial infarction within the previous 3 months, unstable
arrhythmias, and/or unstable angina
8. Known clinically significant liver disease, including active viral, alcoholic, or
other hepatitis, cirrhosis, and inherited liver disease or current alcohol abuse

or a fasting plasma glucose = 160 mg/dL (or 8.8 mmol/L)
10. Anticipation of need for a major surgical procedure (requiring general anesthesia)
during the study period
11. Any evidence of severe or uncontrolled systemic diseases, including uncontrolled
hypertension (defined by blood pressure higher than 150/90mmHg despite effective
anti-hypertensive treatments) and active bleeding diatheses, which in the
investigator's opinion makes it undesirable for the patient to participate in trial or
which would jeopardize compliance with the protocol
12. Any anti-cancer therapy, whether investigational or approved, including chemotherapy,
immunotherapy, gene therapy, cancer vaccine, cell therapy, cytokines, hormonal
therapy, and/or radiotherapy) received after standard concurrent chemo-radiotherapy
(CCRT)
13. Persisting toxicity related to prior therapy (NCI CTCAE v. 5.0 Grade > 1); however,
alopecia, sensory neuropathy Grade = 2, or other Grade = 2 not constituting a safety
risk based on investigator's judgment are acceptable
14. Malignancies other than disease under study within 5 years prior to randomization
except for those with a negligible risk of metastasis or death (such as adequately
treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, localized
prostate cancer, or ductal carcinoma in situ)
15. Uncontrolled hypercalcemia (ionized Calcium > 1.5 mmol/L or Calcium > 12 mg/dL or
adjusted serum Calcium = ULN) or symptomatic hypercalcemia requiring bisphosphate or
denosumab
*Patients without history of clinically significant hypercalcemia, receiving either
bisphosphonate or denosumab prophylactically is eligible
** Denosumab receiving patients should agree to switch to bisphosphate, and not
contraindicated for bisphosphate use are eligible
16. Patients with active virus infection requiring systemic treatment at screening 1)
Positive test for HIV infection 2) Active HBV hepatitis: positive for HBsAg and
HBV-DNA, if HBsAg positive but HBV-DNA negative during the screening can participate
