Intended Use

The intended use of Syncor Pharmaceuticals' BT-103-2 seeds is to deliver radiation for brachytherapy in the treatment of cancer with sources in close proximity to, or within, the tumor. These seeds are indicated for permanent interstitial treatment of tumors which are localized and unresectable, and which have a slow growth rate and low to moderate radiosensitivity. Superficial, intrathoracic, and intraabdominal tumors, such as those in the head, neck, lungs, pancreas and prostate are commonly treated in this manner. The seeds may also be implanted in recurrent tumors or in residual tumors following completion of a course of external radiation therapy. Total activity of BT-103-2 seeds required for treatment is dependent upon the tumor volume and the radiation history of the site. To calculate the total activity needed, determine the placement of the sources in the tissue, and evaluate the dose distribution achieved, established practice should be followed.

Device Story

PharmaSeed BT-103-2 are radioactive seeds for permanent interstitial brachytherapy; used for localized, unresectable tumors. Seeds implanted directly into or near tumor tissue; provide localized radiation dose. Used in clinical settings by physicians; requires calculation of total activity based on tumor volume and prior radiation history. Benefits include targeted radiation delivery to tumor site while sparing surrounding healthy tissue. Device is a passive radioactive source; no electronic components or software.

Clinical Evidence

No clinical data provided; device relies on established practice for brachytherapy source implantation and dose calculation.

Technological Characteristics

Radioactive brachytherapy seeds for permanent interstitial implantation. Passive device; no energy source, software, or connectivity. Materials and specifications not detailed in provided text.

Indications for Use

Indicated for permanent interstitial brachytherapy treatment of localized, unresectable tumors with slow growth and low-to-moderate radiosensitivity. Applicable to superficial, intrathoracic, and intraabdominal tumors (e.g., head, neck, lung, pancreas, prostate), including recurrent or residual tumors post-external radiation.

Regulatory Classification

Identification

A radionuclide brachytherapy source is a device that consists of a radionuclide which may be enclosed in a sealed container made of gold, titanium, stainless steel, or platinum and intended for medical purposes to be placed onto a body surface or into a body cavity or tissue as a source of nuclear radiation for therapy.

Special Controls

*Classification.* Class II (special controls). A prostate seeding kit intended for use with a radionuclide brachytherapy source only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Dear Mr. Gilmore:

We have reviewed your Section 510(k) notification of intent to market the device and we have determined the device is substantially equivalient (for the incluse stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce pror to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of device, good manufacturing and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivation assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notfication submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions and advertising of your device, please contact the Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number [phone] or [phone] or at its internet address "http://www.fda.gov/cdrh/dsmaldsmamain.html".

Sincerely yours,

Daniel G. Schultz, M.D. Captain, USPHS Director, Division of Reproductive, Abdominal, and Radiological Devices Office of Device Evaluation Center for Devices and Radiological Health
