4 terms

fda approval regulatory

"CorMedix received U.S. Food and Drug Administration approval of DefenCath® in 2023"

FDA approval is the U.S. Food and Drug Administration’s formal authorization for a drug, vaccine, or medical device to be marketed and sold after reviewers determine it meets standards for safety and effectiveness. For investors it’s a pivotal milestone because it opens the door to legal, large-scale sales and can sharply boost revenue potential while reducing regulatory uncertainty—like receiving a safety certificate that lets a new bridge carry traffic and tolls.

first-in-human study medical

"With a first-in-human study of ATNM-400 underway"

A first-in-human study is the initial clinical trial in which an experimental drug, biologic or medical device is given to people for the first time to assess safety, tolerability and how the body processes the product. These studies typically enroll a small number of participants and use controlled, stepwise dosing (for example single-ascending or multiple-ascending dose cohorts) under regulatory and ethics oversight; they are not designed primarily to prove therapeutic benefit and often inform dose selection and safety monitoring for later-phase trials.

actinium-225 technical

"deep expertise in actinium-225"

Actinium-225 is a rare, radioactive form of the metal actinium used as a microscopic radiation source in some cancer treatments; it emits very strong, short-range radiation that can destroy diseased cells when attached to a carrier drug. Investors pay attention because supply is limited and production is complex, so shortages or cost changes can directly affect the development, manufacturing and valuation of companies pursuing therapies that rely on this scarce medical “fuel.”

radiopharmaceuticals medical

"radiopharmaceuticals have become one of the most dynamic areas"

Radiopharmaceuticals are medicines that carry tiny amounts of radioactive material to help doctors see or treat disease inside the body, acting like a tracer dye for imaging or a microscopic guided missile for targeted therapy. They matter to investors because their safety, regulatory approval, production complexity, short shelf life and hospital reimbursement determine how quickly they can reach patients and generate revenue, affecting a company’s sales potential and risk profile.

NEW YORK, Oct. 15, 2026 /PRNewswire/ -- Actinium Pharmaceuticals, Inc. (NYSE American: ATNM) ("Actinium" or the "Company"), a pioneer in the development of targeted radiotherapies, today announced the appointment of Matt David, M.D., as Chief Financial Officer. Dr. David will lead the Company's finance, accounting, capital markets and investor relations functions and will also serve as the Company's principal financial officer.

Dr. David brings more than two decades of experience across biopharmaceutical operating leadership, healthcare investment banking and equity research. He joins Actinium from CorMedix Inc. (Nasdaq: CRMD), where he most recently served as Executive Vice President and Chief Business Officer. He joined CorMedix in 2020 as Executive Vice President and Chief Financial Officer. During his tenure, CorMedix received U.S. Food and Drug Administration approval of DefenCath® in 2023, launched the product commercially in 2024, and in 2025 acquired a commercial anti-infectives company, becoming a diversified, commercial-stage specialty pharmaceutical company.

Sandesh Seth, Actinium's Chairman and CEO, said, "Matt is an exceptional addition to our leadership team. He has been a public company CFO, an interim CEO and a CBO, and he has helped guide a company from late-stage development through FDA approval, commercial launch and a transformational acquisition. Combined with his medical background and his years advising and financing biopharmaceutical companies on Wall Street, Matt brings a rare blend of scientific fluency, capital markets expertise and strategic judgment. As we advance ATNM-400, Actimab-A, Iomab-ACT and build on our leadership in radiotherapies, his experience will be invaluable in strengthening our financial operations, engaging with the financial community and helping to guide the company strategically."

Dr. David said, "Actinium has built a differentiated targeted radiotherapy platform at a time when radiopharmaceuticals have become one of the most dynamic areas in oncology drug development. With a first-in-human study of ATNM-400 underway, a clinically validated Actimab-A program and deep expertise in actinium-225, I believe the Company has multiple significant value drivers ahead. I am excited to join the leadership team and look forward to helping position Actinium to execute on its strategy and deliver value for patients and shareholders."

Prior to his roles at CorMedix, Dr. David served as Head of Strategy at Ovid Therapeutics Inc. (Nasdaq: OVID). Before moving into industry, he spent more than a decade in healthcare investment banking, including at BofA Merrill Lynch, Thomas Weisel Partners and Piper Jaffray, where he advised biopharmaceutical companies on financings and strategic transactions, and at Lehman Brothers as an equity research associate covering the pharmaceutical sector. Dr. David received his M.D. from NYU School of Medicine and was a surgery resident at Beth Israel Hospital. He received his undergraduate degree in Chemistry from Dartmouth College.

About Actinium Pharmaceuticals, Inc.

Actinium is a pioneer in targeted radiotherapies designed to improve outcomes for patients with cancer. The company employs a biology-driven approach to develop differentiated radiopharmaceuticals for solid tumors and hematologic malignancies. Its mission is to transform cancer treatment through innovative radioconjugates that maximize therapeutic efficacy while minimizing toxicity to healthy tissue by combining expertise in tumor biology, translational medicine, and radiochemistry. Since inception, Actinium has focused on developing innovative radiotherapies. Its pipeline reflects this strategy across three areas: (1) solid tumor therapeutics including ATNM-400 and Actimab-A with pan-tumor potential; (2) Actimab-A as a therapeutic backbone for acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) in collaboration with the National Cancer Institute (NCI); and (3) targeted conditioning agents including Iomab-B for bone marrow transplant and Iomab-ACT for cell and gene therapy conditioning. ATNM-400 targets a novel antigen distinct from PSMA and has demonstrated preclinical activity across metastatic castration-resistant prostate cancer (mCRPC), non-small cell lung cancer (NSCLC), and breast cancer, and is being evaluated in a first-in-human Phase 1 study in mCRPC. Actimab-A has shown improved survival in relapsed/refractory AML with CLAG-M and is advancing toward a Phase 2/3 trial, with additional development ongoing through a CRADA with the NCI. Actinium is also advancing preclinical solid tumor programs and holds ~250 patents and patent applications, including intellectual property related to cyclotron-based production of Ac-225.
