The Safety and Dosimetry Study of 177Lu-LNC1004 Injection
Phase I, Open-Label Study of the Safety and Dosimetry of a 4-Dose Regimen of Escalating Doses of 177Lu-LNC1004 Injection in Adult Patients With Advanced Fibroblast Activation Protein (FAP)-Positive Solid Tumors
This proposal is a phase I, open-label study of a 4-Dose Regimen of Escalating Doses of 177Lu-LNC1004 Injection in patients with recurrent or metastatic, fibroblast activation protein-positive solid tumors.
In the clinical development, we aim to demonstrate the following:
- 177Lu-LNC1004 Injection is safe and tolerable at therapeutic dose.
- Determination of dose(s) to be used in the expansion phase. The treatment regimen will consist of a single dose intravenous administration of 177Lu-LNC1004 Injection per 6-week cycle, for a total of 2 cycles. The dose per cycle will be fixed for each patient and will be escalated in 4 different dose levels

Detailed Description
This proposal is a phase I, open-label study of a 4-Dose Regimen of Escalating Doses of 177Lu-LNC1004 Injection in patients with recurrent or metastatic, fibroblast activation protein-positive solid tumors. The treatment regimen will consist of a single dose intravenous administration of 177Lu-LNC1004 Injection per 6-week cycle, for a total of 2 cycles. The dose per cycle will be fixed for each patient and will be escalated in 4 different dose levels, from 30 mCi to 100 mCi (1.11 - 3.7 GBq).
This classic 3+3 design includes 3 patients for the first dose level group. If no DLT occurs, 3 patients will be enrolled at the next dose level. If a DLT occurs at a certain dose level, 3 additional patients will be enrolled at the previous dose level. The highest dose with no more than 1 DLT out of 6 patients will be defined as MTD. If there is no MTD observed after the dose escalation up to 100 mCi, a comprehensive evaluation should be made by investigator and sponsor to determine whether an escalation to a higher dose can be conducted or not based on the known safety, radiation dose and efficacy characteristics.

Subjects not considered WOCBP are those without menses for ≥ 12 consecutive months, and those who have undergone hysterectomy and/or bilateral salpingo-oophorectomy. WOCBP must be willing to use acceptable methods of birth control (i.e., a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, or condom with spermicide, or abstinence) for the duration of the study and 6 months after the last dose of treatment.
- Male participants with partners of childbearing potential are required to use barrier contraception in addition to having their partner use another method of contraception during the study and for 6 months after the last dose of treatment. Male participants will also be advised to abstain from sexual intercourse with pregnant or lactating women, or to use condoms.
- Previous surgery no less than 4 weeks prior to study entry.
Exclusion Criteria:
- Women who are pregnant or breastfeeding
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to 177Lu-LNC1004 as assessed from medical records
- Participant has had prior chemotherapy or radical radiotherapy within 4 weeks before the first administration of study drug
