Trial ID Title Status Sponsor Phase Start Date Summary
NCT00001575 ↗ Anti-Tac(90 Y-HAT) to Treat Hodgkin's Disease, Non-Hodgkin's Lymphoma and Lymphoid Leukemia Completed National Cancer Institute (NCI) Phase 1/Phase 2 1997-04-01 This study will examine the use of a radioactive monoclonal antibody called yttrium 90-labeled humanized anti-Tac (90 Y-HAT) for treating certain cancers. Monoclonal antibodies are genetically engineered proteins made in large quantities and directed against a specific target in the body. The anti-Tac antibody in this study is targeted to tumor cells and is tagged (labeled) with a radioactive substance called Yttrium-90 (Y-90). The study will determine the maximum tolerated dose of 90Y-HAT and examine its safety and effectiveness. Patients 18 years of age and older with Hodgkin's disease, non-Hodgkin's lymphoma and lymphoid leukemia who have proteins on their cancer cells that react with anti-Tac may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, electrocardiogram (EKG), chest x-ray, computed tomography (CT) scan or ultrasound of the abdomen, positron emission tomography (PET) scan of the neck and body, and skin test for immune reactivity to antigens (similar to skin tuberculin test). Before beginning treatment, participants may undergo additional procedures, including the following: - Patients with suspicious skin lesions have a skin biopsy. An area of skin is numbed and a circular piece of skin about 1/4-inch diameter is removed with a cookie cutter-like instrument. - Patients with hearing loss have a hearing test. - Patients with neurological symptoms have a lumbar puncture (spinal tap). A local anesthetic is given and a needle is inserted in the space between the bones in the lower back where the cerebrospinal fluid circulates below the spinal cord. A small amount of fluid is collected through the needle. - Patients who have not had a bone marrow biopsy within 6 months of screening also undergo this procedure. The skin and bone at the back of the hip are numbed with a local anesthetic and a small piece of bone is withdrawn through a needle. Patients receive 90 Y-HAT in escalating doses to determine the highest dose that can be safely given. The first group of three patients receives a low dose and, if there are no significant side effects at that dose, the next three patients receive a higher dose. This continues with subsequent groups until the maximum study dose is reached. 90 Y-HAT is given through a vein (intravenous (IV)) over a 2-hour period. In addition, a drug called Pentetate Calcium Trisodium Inj (Ca-DTPA) is given via IV over 5 hours for 3 days to help reduce the side effects of the 90Y-HAT. In some patients, the 90 Y-HAT may also be attached to a radioactive metal called Indium-111 to monitor what happens to the injected material. During infusion of the drug, patients undergo PET scanning to trace the path of the injected material in the body. For this procedure, the patient lies in the scanner, remaining in one position during the entire infusion. Blood and urine specimens are collected periodically over a 6-week period following the infusion to determine the level of the radioactive antibody. Bone marrow, lymph node, or skin biopsies may be done to determine how much of the antibody entered these sites. Patients whose disease remains stable or improves with therapy may receive up to six more infusions of 90 Y-HAT, with at least a 6-week interval between treatments.

Summary

Last updated: February 10, 2026

Pentetate zinc trisodium, also known as zinc EDTA, is primarily used as an antioxidant and for chelation therapy. The drug has not yet achieved widespread approval for new indications outside its established use. Ongoing clinical trials focus on chelation therapy for heavy metal poisoning and potential applications in neurodegenerative diseases. Market prospects are limited by existing generic options, regulatory status, and the drug’s narrow clinical application scope. Future growth depends on successful trial outcomes, regulatory approvals for new indications, and potential market expansion strategies.


What Is the Current Status of Clinical Trials for Pentetate Zinc Trisodium?

Overview of Clinical Trial Activity

As of 2023, pentetate zinc trisodium has limited active clinical trials. Most are phase 2 or later, centered on chelation therapy for heavy metal poisoning and related conditions. Several registered trials aim to evaluate its safety and efficacy in reducing heavy metal burden. Notably:

  • Heavy Metal Detoxification: Trials evaluate the drug’s ability to chelate zinc, cadmium, lead, and arsenic.

  • Neurodegenerative Diseases: Emerging research investigates potential neuroprotective effects, particularly for Alzheimer’s and Parkinson’s disease, but these are preliminary and in early phases.
