177Lu-JH04 in Patients with FAP-Positive Tumors

October 9, 2024 updated by: First Affiliated Hospital of Fujian Medical University

Safety, Dosimetry and Treatment Response of 177Lu-JH04 in Patients with FAP-Positive Tumors

This is a pilot study to assess the dosimetry, toxicity and response of 177Lu-JH04, a new FAP-targeted radiopharmaceutical, in patients with FAP-Positive Tumors. All patients underwent 68Ga-FAPI PET/CT for selection and were successively divided into three groups of 3 people each.The three groups received successively an approximately 3.70 GBq (100 mCi), 5.55 GBq (150 mCi) and 7.40 GBq (200 mCi) of 177Lu-JH04 up to 4 cycles.

Detailed Description

Cancer-associated fibroblasts (CAFs) are an integral part of the tumor microenvironment and present abundantly in the stroma of multiple tumor entities. Fibroblast activation protein (FAP), as a specific marker protein of CAFs, is overexpressed on more than 90% of malignant tumors& limited and expression in normal tissues, making it an appropriate target for diagnosis and therapy of numerous malignant tumors. Currently, several radiopharmaceuticals targeting FAP for radionuclide therapy have been developed, such as 177Lu-FAPI-46, 177Lu-FAP-2286, and showed high efficacy and reasonable toxicity profile in tumor treatment. 177Lu-JH04, a novel radiopharmaceutical targeting FAP, demostrated high stability in vitro and in vivo, and can accumulate specifically in tumors with high binding affinity, safety, and selectivity in preclinical studies. In this study, we assess the dosimetry, toxicity and response of 177Lu-JH04 for the treatment of patients with advanced metastatic cancers after exhaustion of all other treatment options.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Toxic and side effect
Time Frame: through study completion, an average of 2 weeks
The white blood cell count, granulocyte count, platelet count, hemoglobin count and serum biochemicals of each patient before and after each treatment were recorded and compared. And the weight (in kilograms) of the patients was monitored. Adverse events were categorized using the Common Toxicity Criteria for Adverse Events 5.0.
through study completion, an average of 2 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Dosimetry of normal organs and tumors
Time Frame: through study completion, an average of 4 weeks
The semiquantitative dosimetry will be performed based on SPECT/CT acquisitions after the first administration of 177Lu-JH04. The dose delivered to normal organs and tumors will be recorded.
through study completion, an average of 4 weeks

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Treatment Response
Time Frame: through study completion, an average of 3 months
