Theragenic

What Theragenic does

Theragenics Corporation is a private specialty medical device and radioisotope manufacturing company headquartered in Buford, Georgia, founded in 1981 as Nuclear Medicine, Inc. by Georgia Institute of Technology physicists. The company operates two principal business segments: (1) a brachytherapy franchise built around proprietary LDR brachytherapy seeds — TheraSeed® Palladium-103, AgX100® Iodine-125, and (since 2025) Cesium-131 distributed under license from GT Medical Technologies — together with a full ecosystem of delivery systems (TheraStrand®, TheraSleeve®, TheraLoad®, AnchorLoad®, C20™ cartridges, preloaded needle trays, intra-ocular carriers) and fiducial markers; and (2) a radioisotope contract manufacturing organization (CMO) business leveraging 14 cyclotrons at a 134,000 sq ft facility to produce Copper-64, Pd-103, I-125, Indium-111, Gallium-67, and Yttrium-90 for radiopharmaceutical partners, including a March 2026 large-scale Copper-64 supply agreement with Clarity Pharmaceuticals.

The company's business model combines direct sales of brachytherapy seeds and accessories to hospitals, cancer centers, and urology/radiation oncology practices across more than 40 countries, with multi-year B2B contract manufacturing agreements with pharmaceutical partners developing radiopharmaceuticals. GTM is sales-led for the medical device side, supported by industry conference participation (ABS, ASTRO, EANM, LUGPA) and a physician finder tool, while the CMO side is a dedicated B2B channel with named account management. Theragenics operates through wholly-owned subsidiaries Galt Medical (vascular/interventional devices, Garland TX), CP Medical (wound closure and specialty sutures, Norcross GA), and Arrotek Medical (medical device design consultancy with facilities in Sligo, Ireland and North Attleboro, MA). The company is owned by Juniper Investment Company following a mid-2010s take-private transaction.

Partnerships

Two partnerships are on record, tiered core.

• Clarity PharmaceuticalscoreStrategic or Co-development Partner · 25 March 2026Large-scale manufacturing supply agreement for copper-64 isotope production at Theragenics' 134,000 sq ft facility with 14 cyclotrons near Atlanta, Georgia. The agreement supports Clarity's anticipated commercial launch of 64Cu-SAR-bisPSMA for prostate cancer imaging, pending Phase III trial completion (AMPLIFY and CLARIFY) and FDA approval. Theragenics' facility can produce approximately 100Ci of copper-64 per day per cyclotron, translating to around 2,000 patient doses per day. This partnership expands Clarity's copper-64 supply network alongside SpectronRx and Nusano.
• GT Medical TechnologiescoreChannel Partner/ Reseller/ DistributorTheragenics is an authorized distributor of Cesium-131 LDR brachytherapy seeds, which are manufactured by GT Medical Technologies, Inc. (Tempe, AZ). Theragenics distributes Cesium-131 seeds and associated product offerings including loose seeds, strands, cartridges, and braided suture options.

Scale indicators8 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Elekta: Large radiation therapy and radiosurgery equipment vendor offering HDR brachytherapy afterloaders, treatment planning, and related disposables. Competes with Theragenics in the broader radiation oncology/brachytherapy category, though Theragenics specializes in LDR seeds while Elekta's portfolio is broader.
• iba (Ion Beam Applications): Leading global supplier of cyclotrons and integrated radiopharma production solutions, including for medical radioisotope production. Comparable to Theragenics' core cyclotron-based isotope manufacturing infrastructure, though iba sells equipment and turnkey facilities while Theragenics operates its own.
• Siemens Healthineers (Varian): Through its Varian acquisition, Siemens Healthineers is a major radiation oncology incumbent offering external beam, brachytherapy software, and treatment delivery systems — competing for hospital wallet share that might otherwise fund LDR brachytherapy seeds from Theragenics.

Direct peers

• Curium Pharma: Global radiopharmaceutical manufacturer and CMO producing medical isotopes (Tc-99m, Mo-99, I-131, Lu-177) and offering contract manufacturing services — a direct peer to Theragenics' radioisotope CMO segment and a competitor for radiopharma supply contracts.
• IsoRay Medical: U.S. brachytherapy seed manufacturer (Cs-131 and Pd-103) directly competing with Theragenics' TheraSeed and Cs-131 distribution in prostate and other cancer brachytherapy. Closely comparable specialty medical device peer.
• GT Medical Technologies: Manufacturer of Cesium-131 brachytherapy seeds (GammaTile therapy for brain tumors and other indications). Theragenics is an authorized distributor of GT's Cs-131 products but also operates in the same brachytherapy space.
• NorthStar Medical Radioisotopes: Commercial-scale producer of Mo-99/Tc-99m and other medical radioisotopes in the U.S. Comparable to Theragenics' cyclotron-based isotope production business and competes for radiopharma manufacturer supply agreements.
• Nusano: U.S.-based medical isotope production company building large-scale production capacity for radioisotopes used in diagnostics and therapeutics, including Cu-64. Directly competes with Theragenics for radiopharmaceutical CMO contracts (e.g., Clarity Pharmaceuticals' Cu-64 supply network).
• SpectronRx: Radiopharmaceutical CDMO offering large-scale isotope production and radiolabeling services, including Cu-64 supply to Clarity Pharmaceuticals. Direct competitor to Theragenics in radioisotope CMO and radiopharma contract manufacturing.

Emerging players

• Teleflex: Medical device manufacturer with vascular access, interventional, and specialty surgical product lines that overlap with Theragenics' Galt Medical subsidiary. Comparable as a peer across the interventional access business, though Theragenics is more concentrated in brachytherapy and radioisotopes.
