6 terms

actinium-225 (ac-225) medical

"Cardinal Health ... announced a significant expansion of its Actinium-225 (Ac-225) production capabilities"

Actinium-225 (Ac-225) is a rare, highly radioactive isotope used as a “warhead” in targeted cancer treatments that deliver powerful alpha particles directly to tumor cells while sparing most healthy tissue. Investors watch Ac-225 because its medical promise, very limited and complex production, regulatory approval pathway, and fragile supply chain can create large commercial opportunities or bottlenecks for companies developing radiopharmaceuticals and supporting infrastructure.

drug master file (dmf) regulatory

"The addition of a high-capacity production line to its Drug Master File (DMF)"

A drug master file (DMF) is a confidential regulatory submission that describes in detail how a drug ingredient, component, or packaging is manufactured, tested and controlled, similar to giving a regulator a private recipe and safety checklist. It matters to investors because an accepted DMF helps regulators trust product quality and can speed or enable approvals, while protecting proprietary manufacturing know‑how and reducing supply or regulatory risk for a drug program.

cGMP-compliant regulatory

"increase Cardinal Health's supply of cGMP-compliant Ac-225 for use in investigational"

cGMP-compliant means a manufacturer follows the current Good Manufacturing Practices required by regulators to ensure products are made safely, consistently and with documented quality controls. For investors, cGMP compliance is like a certified clean kitchen and recipe book for a company’s manufacturing: it reduces the risk of product contamination, regulatory sanctions or recalls, supports reliable supply and can be essential for getting and keeping market approvals.

alpha-emitting radionuclide medical

"Ac-225 is an alpha-emitting radionuclide that can be linked to molecules"

An alpha-emitting radionuclide is a radioactive isotope that releases alpha particles—small, highly energetic but short-range bits of radiation—often used to deliver destructive energy directly to diseased cells in targeted medical therapies. Investors care because these materials underpin a class of precision cancer treatments and carry special manufacturing, regulatory, safety and supply-chain considerations that affect development costs, clinical success odds, regulatory approval risk and commercial potential, much like a specialty ingredient that is hard to source but central to a product’s value.

theranostics medical

"at the company's Center for Theranostics Advancement (CTA) in Indianapolis, Indiana"

Theranostics combines a medical test with a targeted treatment so the same approach both finds disease and delivers therapy—like a guided missile that first locates a target then destroys it. For investors, it matters because pairing diagnosis and therapy can speed identification of patients who will benefit, reduce wasted treatments, create dual revenue streams (tests plus drugs), and alter regulatory and reimbursement dynamics that affect commercial potential.

targeted alpha therapies medical

"supporting the rapidly growing global demand for targeted alpha therapies"

Targeted alpha therapies are medicines that attach tiny sources of powerful, short-range radiation to molecules that seek out cancer cells, delivering a concentrated, local kill while sparing nearby healthy tissue. Investors watch them because their precision can mean stronger clinical benefits and smaller side effects than traditional treatments, which can lead to faster regulatory approval, high pricing power, and significant commercial opportunity—but also complex manufacturing and regulatory risks.

DUBLIN, Ohio, April 1, 2026 /PRNewswire/ -- Cardinal Health (NYSE:CAH) today announced a significant expansion of its Actinium-225 (Ac-225) production capabilities at the company's Center for Theranostics Advancement (CTA) in Indianapolis, Indiana. The addition of a high-capacity production line to its Drug Master File (DMF) will substantially increase Cardinal Health's supply of cGMP-compliant Ac-225 for use in investigational therapeutic drug products and future commercial manufacturing novel therapies.

Ac-225 is an alpha-emitting radionuclide that can be linked to molecules like those designed to selectively target cancer cells. New, cutting-edge Ac-225 drug products are being developed and are becoming an increasingly promising new class of therapies for cancers including prostate, neuroendocrine, breast, colon, melanoma, and lymphoma. Despite growing demand, worldwide clinical progress has been slowed by limited availability.

Since announcing routine Ac-225 production globally at scale at the end of 2024, Cardinal Health has quadrupled its weekly output. The company expects to continue increasing production capacity in 2026, supporting the rapidly growing global demand for targeted alpha therapies.

"Expanding our Ac-225 production capacity is a critical step forward for the industry and for patients," said Shane Thrasher, Vice President of Radiopharmaceutical Manufacturing, Cardinal Health Nuclear & Precision Health Solutions. "As targeted alpha therapies progress through clinical trials, reliable access to Ac-225 remains essential. This expanded capacity strengthens our ability to meet customer needs today while preparing for significantly larger commercial volumes that may occur in the coming years."

Cardinal Health's expanded production increases access to material for research and clinical development. To date, Cardinal Health's Ac-225 has supported more than 15 clinical trials worldwide, reflecting broad engagement with pharmaceutical innovators advancing targeted alpha therapies.

"The reliable availability of Ac-225 is essential for advancing targeted alpha therapies and enabling innovation in clinical research," said Eric Bischoff, Chief of Product Development and Operations at RayzeBio (a Bristol Myers Squibb Company). "Cardinal Health's commitment to expanding production capacity helps ensure a more robust supply chain, accelerating our ability to drive progress and deliver new treatment options to patients."

Cardinal Health has supported regulatory applications for cGMP-compliant Ac-225 for customers across multiple regions worldwide.
