Criteria
Inclusion Criteria:1. Patients aged 18 years or older at the time of informed consent, who are
pathologically (histologically or cytologically) diagnosed with thymic carcinoma for
primary or metastatic thymic lesions, are included. They are preferred to be positive
for CD5 or c-KIT by immunohistochemical staining. For those with non-squamous
epithelial carcinoma negative for p40 or p63, non-primary cases should be excluded
based on their clinical and pathological findings. In addition, those with thymoma are
excluded.
2. Patients with unresectable advanced thymic carcinoma (equivalent to stage IVa or IVb
of Masaoka-Koga classification), metastatic or recurrent, who have not been treated
with systemic cancer chemotherapy.
Or, in the case of stage III Masaoka-Koga classification, patients who are judged to
be incapable of radical resection (R0 resection is not possible due to the combined
resection of invasive lesions in surrounding organs (pericardial sac, lung, great
vessels, etc.) or who are not eligible for curative treatment with chemoradiotherapy.
A history of adjuvant chemotherapy and radiation therapy is acceptable for
perioperative adjuvant therapy prior to the finding of recurrence. If
platinum-containing cancer chemotherapy has been administered as adjuvant therapy, it
is eligible if there is an interval of at least 24 weeks before registration.
3. No symptomatic brain metastases, carcinomatous meningitis, or spinal metastases
requiring radiotherapy or surgery
4. No prior history of an antiangiogenetic agent targeting VEGFR for thymic carcinoma
5. Not receiving radiotherapy within 14 days before registration Male participants
6. A male participant must agree to use contraception as detailed in Appendix 3 of this
protocol during the treatment period and for at least 135 days after the last dose of
study treatment and refrain from donating sperm during this period.

3), not breastfeeding, and at least one of the following conditions applies:

treatment period and for at least 120 days after the last dose of study
treatment.
8. The participant provides written informed consent for the trial
9. Have measurable disease based on RECIST 1.1. Lesions situated in a previously
irradiated area are considered measurable if progression has been demonstrated in such
lesions

HCV infection or who meet the following criteria 10.1 Hepatitis B positive subjects
Participants who are HBsAg positive are eligible if they have received HBV antiviral
therapy for at least 4 weeks and have an undetectable HBV viral load prior to
registration.
Participants should remain on anti-viral therapy throughout the study intervention and
follow local guidelines for HBV anti-viral therapy post-completion of the study
intervention.
10.2 Participants with a history of HCV infection Participants are eligible if HCV
viral load is undetectable at screening. Participants must have completed curative
anti-viral therapy at least 4 weeks prior to registration.
11. Have provided archival tumor tissue sample or newly obtained core or excisional biopsy
of a tumor lesion not previously irradiated. Formalin-fixed, paraffin-embedded (FFPE)
tissue blocks are preferred to slides. Newly obtained biopsies are preferred to
archived tissue.
12. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
Evaluation of ECOG is to be performed within 14 days before registration.
13. Have adequate organ function as defined in the following table (Table 8). Specimens
must be collected within 14 days prior to registration.
14. Have a predicted life expectancy of >12 weeks

(patients with QTcF > 480 ms)
4. Has a LVEF below the institutional normal range, as determined by multigated
acquisition (MUGA) or echocardiogram (ECHO)
5. A WOCBP who has a positive urine pregnancy test within 72 hours prior to registration
(see Appendix 3). If the urine test is positive or cannot be confirmed as negative, a
serum pregnancy test will be required
6. Has urine protein ≥1 g/24 hours Note: Participants with proteinuria ≥2+ (≥100 mg/dL)
on urine dipstick testing (urinalysis) will undergo 24-hour urine collection for
quantitative assessment of proteinuria
7. Has had major surgery within 3 weeks prior to the first dose of study interventions
8. Has clinically significant cardiovascular disease within 12 months from the first dose
of study intervention, including New York Heart Association Class III or IV congestive
heart failure, unstable angina, myocardial infarction, cerebral vascular accident, or
cardiac arrhythmia associated with hemodynamic instability
