In-hospital Neutron Irradiator (IHNI)-Based Boron Neutron Capture Therapy (BNCT) in the Treatment of Malignant Melanoma

Detailed Description
This is a single BNCT-facility, non-randomized, non-comparative, open-label, phase I to II clinical trial to determine the value of IHNI in the performance of BNCT. Before patients are recruited in this study, they must have been confirmed as malignant melanoma by biopsy and pathological analysis. Then they will receive a boron bio-distribution test, only patients whose boron concentration in tumor tissue is >1.5 times that in the blood will be enrolled. Before patients being irradiated in IHNI, they will be infused Boronophenylalanine (BPA)-fructose solution intravenously at a dose of 350mg/kg over 90 minutes, and then blood will be withdrawn from the patient at different time points to measure boron concentration. The start point and duration of irradiation will be determined based on the boron concentration in blood and the boron bio-distribution curve.
IHNI locates in Fangshan District, Beijing, China. The recruitment of patients, and their evaluation and medical care before and after BNCT will be done in the Third Xiangya Hospital, Changsha, China.
All patients will be evaluated for response by biopsy and pathological analysis, Positron Emission Computed Tomography (PET-CT), Computed Tomography (CT) or magnetic resonance imaging (MRI).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Boronophenylalanine and IHNI-based BNCT
|
Patients will be infused Boronophenylalanine (BPA)-fructose solution intravenously at a dose of 350mg/kg over 90 minutes.
After BPA infusion, patients will receive neutron irradiation in IHNI for a certain period of time based on his boron bio-distribution curve and BPA concentration in the blood.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of participants showing CR/PR to IHNI-based BNCT
Time Frame: baseline and 2 years
|
CT scan will be performed on each patient before and 2 years after irradiation, up to a maximum of 2 lesions of the longest diameter (unit: millimeter, mm) will be selected as target lesion(s).
The diameter of the targeted lesion(s) will be measured on CT images.
The change in the diameter of the targeted lesion(s) will be used to evaluate the patient's treatment response to IHNI-based BNCT according to Response Evaluation Criteria in Solid Tumors (RECIST).
RECIST consists of four types of response: complete response (CR), partial response (PR), Stable Disease (SD), and Progressive Disease (PD).
The percentage of participants who show CR/PR will be used to evaluate the efficiency of IHNI-based BNCT.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of participants with treatment-related adverse events
Time Frame: 1 week, 1 month, 3 months, 6 months, 1 year and 2 years
|
Physical examination, biochemical profile, routine blood test, and urine analysis will be performed on each patient at 1 week, 1 month, 3 months, 6 months, 1 year and 2 years after irradiation.
All these results will be used to assess the grade of treatment-related adverse events according to Acute Radiation Morbidity Scoring Criteria and Late Radiation Morbidity Scoring Scheme from the Radiation Therapy Oncology Group (RTOG) and the European Organization for Research and Treatment of Cancer (EORTC).
The percentage of adverse event at each grade will be used for the evaluation of the safety of IHNI-based BNCT.

Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of participants of improved life quality.
Time Frame: baseline and 1 year
|
This is to understand whether patients' life quality will be improved by BNCT, based on the Karnofsky performance status (KPS) score (unit: percentage, %) before and 1 year after irradiation.
Questionnaires will be given to each patient at these two time points.
The increase in KPS score after irradiation will be regarded as a reflection of improved life quality, and the percentage of participants who show improved life quality will be used to evaluate of benefits of IHNI-based BNCT.
