treatment
- Positive FAP expression confirmed by FAP PET/CT
- Sufficient bone marrow capacity and organ function
Key Exclusion Criteria:
- High intensity and large amounts of off-target uptake by FAP molecular imaging, and
were assessed as inappropriate for [177Lu]Lu-XT117 therapy by the investigators

immunotherapy, and other investigational drugs) ≤28 days before receiving study
therapy; previous treatment with Chinese medicine with anti-tumor indications within 2
weeks before receiving study therapy

- Clinically significant serious cardiovascular disease, including but not limited to:
a. >Grade II congestive heart failure as per New York Heart Association (NYHA) ; b.
Unstable angina pectoris or myocardial infarction within 6 months before the first
administration of the study drug; c. Severe arrhythmia within 6 months prior to the
first administration; d. Poorly controlled hypertension (patients who keep the blood
pressure to ≤ Grade 2 hypertension [CTCAE5.0] with hypotensor are allowed for
enrollment); e. QTc>450 ms (male) or 470 ms (female), congenital prolonged QT
syndrome, and use of medications that prolong QT
- Clinically serious thromboembolic disease within 6 months prior to the first
administration of the study drug

- History of non-infectious interstitial lung disease (ILD), such as idiopathic
pulmonary fibrosis, idiopathic interstitial pneumonia, pneumoconiosis, and
drug-related interstitial pneumonia, or severe impairment of lung function
- Had other malignancies within 5 years prior to screening (except clinically cured
early stage malignancies)
- Primary central nervous system (CNS) tumor or symptomatic CNS metastasis, expect:
- Subjects with asymptomatic brain metastases;
- Subjects whose CNS lesions were stable for ≥4 weeks after local treatment and who
stopped glucocorticoid or anticonvulsant therapy at least 2 weeks prior to study
drug administration could be enrolled;
- Uncontrolled pleural effusion, pericardial effusion, or ascites requiring repeated
drainage
