Detailed Description
This study will enroll patients with metastatic uveal melanoma that have failed at least one form of therapy from a single academic medical center in the United States. All participants will be informed about the study and potential risks and required to provide written informed consent prior to undergoing study-related procedures. A continual reassessment method (CRM) design will be used for this clinical trial. The study proposes single patient cohorts with dose escalation starting at 4.7 microCi of 225Ac-MTI-201 after each cohort in the absence of safety concerns (2-fold increases for doses and lower dose increases between higher doses). Dose Limiting Toxicities will be assessed using the CTCAE version 5.0 criteria.
The participants who meet the eligibility requirements will be administered a single intravenous dose of 225Ac-MTI-201. After study treatment, the study participants will stay overnight at the study center, undergo study procedures (i.e. vital signs, physical exam, multiple blood and urine sample collections) and will be scheduled to return to the clinic at 48 hours and for additional appointments weekly clinic visits the first month and on Week 9 for health status assessments, including physical exams, complete blood chemistry, and EKG. Tumor measurements every 8 weeks in first year post-injection; extended to 12 weeks in year 2; every 16 weeks in year 3, and 24 weeks in years 4 and 5. The clinic visits will involve seeing a study doctor plus radiological tests (such as MRI and/or CT scans) to see how the metastatic uveal melanoma has responded to the study drug. The protocol and informed consent documents have been reviewed and approved by the hospital human subjects review board and the study will be performed in accordance with the Declaration of Helsinki.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Histologically confirmed metastatic uveal melanoma.
- Progression after at least one prior line of therapy for metastatic uveal melanoma. Liver directed therapy (e.g., hepatic arterial embolization, isolated hepatic perfusion) will count as one line of therapy. Should any additional treatment(s) receive regulatory approval for metastatic uveal melanoma during the conduct of this trial, participants (if eligible for the newly approved treatment) would need to demonstrate disease progression on the additional treatment(s) before being eligible to participate in the current study. There is no limit to the number of previous treatments for metastatic disease.
- Participants must have measurable disease per RECIST 1.1.
- Adults, age 18 or over, with no upper age limit.
- ECOG (Eastern Cooperative Oncology Group) performance status of 0-1 (Karnofsky ≥ 70 percent).
Acceptable organ and marrow function as defined below:
- Leucocytes ≥ 3,000/μL
- Absolute neutrophil count ≥ 1,500/μL
- Platelets ≥ 100,000/μL
- Aspartate aminotransferase (AST)/ Alanine aminotransferase (ALT) ≤ 2.5x institutional upper limit of normal (ULN)
- Bilirubin ≤ 1.5x institutional upper limit of normal (ULN)
- Creatinine clearance ≥ 60mL/min/1.73m^2 (measured by Cockcroft-Gault equation using actual body weight in kilograms, and then adjusted for body surface area)
- Male participants who are sexually active, and female participants of childbearing potential must agree to use 2 forms of FDA approved contraceptive methods during treatment with 225Ac-MTI-201 and up to 3 months following treatment.
- Ability to understand and the willingness to sign a written informed consent document.
Exclusion Criteria:
- Prior alpha-particle therapy.
- Has known symptomatic central nervous system (CNS) metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are stable without evidence of progression by imaging for at least four weeks after definitive intervention and using no more than the equivalent of dexamethasone 2 mg/d for the management of vasogenic edema, if necessary. This exception does not include carcinomatous meningitis, which is excluded regardless of clinical stability.
- Participants with an active malignancy requiring anticancer treatment at the time of study entry that, in the judgment of the investigator could impact the results of treatment of metastatic uveal melanoma.
- Pregnant or nursing women. Women of childbearing potential (defined as having had a menstrual cycle within the past 12 months, and not having had a surgical procedure for sterilization) must have a negative pregnancy test (urine or serum) within 7 days of treatment with 225Ac-MTI-201.
- Participants with uncontrolled inter-current illness including, but not limited to, ongoing or active bacterial infection, active hepatitis B/C infection requiring antiviral therapy, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- Immunocompromised participants may be at increased risk of toxicity. Therefore, HIV-positive participants, participants with acquired or congenital immunodeficiency conditions, those on chronic systemic corticosteroids requiring >10 mg of prednisone or equivalent per day will be excluded from participation. (Participants with autoimmune disease who do not require corticosteroids or are maintained on ≤10 mg of prednisone or equivalent per day ARE eligible for participation; for participants with CNS metastases on steroids, exclusion criterion bullet point #2 above will apply).
- Prior external beam radiation therapy to more than 25 percent of the bone marrow.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Maximum Tolerated Dose (MTD) of 225Ac-MTI-201
Time Frame: Within 4 weeks after study drug administration
|
MTD will be determined by testing increasing doses up to 1327 microCi of 225Ac-MTI-201, administered as a single dose via IV on dose escalation cohorts 1 to 12 with 1 to 6 participants each.
The MTD is reached when 6 patients receive the same highest tolerated dose of 225Ac-MTI-201.
If dose-limiting toxicity (DLT) consistently occurs at the next higher dose of 225Ac-MTI-201, then 5 additional doses at the previous dose of 225Ac-MTI-201 will mark the end of clinical trial.
|
Within 4 weeks after study drug administration
|
Number of Participants Who Experienced Dose-Limiting Toxicities (DLTs)
Time Frame: Within 4 weeks after study drug administration
|
The following will constitute a DLT if the occurrence was within 4 weeks post-dose:
|
Within 4 weeks after study drug administration
|
The Number of Participants Who Experienced Serious or Non-Serious Adverse Events
Time Frame: From time of signing the informed consent document until death, or lost to follow-up (approximately 3 years)
|
Vital signs, physical examination, 12-lead EKG, and blood including toxicity on Days 8, 15, 22, and 29: Week 9, Follow-Up (Starting in Week 17) Adverse Event (AE), any new untoward medical occurrence or worsening of a preexisting medical condition in Participant administered study drug and that may or may not have a causal relationship with drug treatment. All AEs will be graded using the NCI CTCAE v5.0 criteria. Serious Adverse Event (SAE); an untoward medical occurrence at any dose that: Results in death; Is life-threatening; Requires inpatient hospitalization or causes prolongation of existing hospitalization; Results in persistent or significant disability/incapacity; Is a congenital anomaly/birth defect; Is an important medical event that may not be immediately life- threatening or result in death or hospitalization but, may jeopardize the participant or may require intervention to prevent one of the other serious outcomes; or, potential drug induced liver injury (DILI). |
From time of signing the informed consent document until death, or lost to follow-up (approximately 3 years)

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Observed Rate of Renal Elimination of 225Ac-MTI-201
Time Frame: 3 to 24 hours post-dose
|
Urine samples will be obtained post-dose as needed up to 24 hours, and renal concentrations (becquerel (Bq)) over time (minutes) determined using validated method that measures 225Ac-MTI-201 radioactivity with standard Wipe Gamma Counter or a specialized gamma spectrometer.
The fraction of the injected activity of the 225Ac-MTI-201 which is ultimately excreted in the urine can be then calculated.
|
3 to 24 hours post-dose
|
Observed Rate of Elimination from Blood of 225Ac-MTI-201
Time Frame: Prior to the initial dose on day 1; 0.042, 0.083, 0.167, 0.333, 0.667, 1.333, 2.333, 24, and 48 hours; day 8; and day 15 post-dose
|
Blood samples will be obtained, and plasma concentrations (becquerel (Bq)) over time (minutes) determined using validated method that measures 225Ac-MTI-201 radioactivity with standard Wipe Gamma Counter or a specialized gamma spectrometer.
The 1-compartment model will be used for describing the pharmacokinetics of 225Ac-MTI-201.
The blood is set as the central compartment; elimination of 225Ac-MTI-201 from this compartment is assumed to occur through a combination of renal and hepatic elimination.
|
Prior to the initial dose on day 1; 0.042, 0.083, 0.167, 0.333, 0.667, 1.333, 2.333, 24, and 48 hours; day 8; and day 15 post-dose
|
Number of Participants Who Experienced a Complete Response (CR), Partial Response (PR), Progressive Disease (PD), or Stable Disease (SD) According to Tumor Lesion Measurement
Time Frame: From time of signing the informed consent document until death, or lost to follow-up (approximately 3 years)
|
Tumor will be measured (mm) at baseline and every 8 weeks in first year unless participant is taken off study; visit frequency is reduced in subsequent years. Follow-up visits past year-3 can be conducted via a review of clinic visit notes and/or telephone contact. Measurable disease is the presence of at least one measurable tumor lesion. At baseline, all lesions (up to five; maximum of two per organ) should be identified as target lesions. All other lesions (or sites of disease) including lymph nodes should be identified as non-target lesions. A lesion identified on a follow-up study not previously observed is considered a new lesion and indicates disease progression. CR is the loss of all target lesions. PR is at least a 30 percent decrease and PD is at least a 20 percent increase in the sum of diameters of target lesions. Stable Disease is defined as having neither sufficient shrinkage or increase to qualify for PR or PD, respectively. |
