Intended Use

The INTRABEAM® System is indicated for radiation therapy treatments. The INTRABEAM® Spherical Applicators are indicated for use with the INTRABEAM® System to deliver a prescribed dose of radiation to the treatment margin or tumor bed during intracavity and intraoperative radiotherapy treatments. The INTRABEAM® Spherical Applicators used with the INTRABEAM System are able to deliver a prescribed dose of intraoperative radiation in conjunction with whole breast irradiation, based upon the medical judgment of the physician. The safety and effectiveness of the INTRABEAM System as a replacement for whole breast irradiation in the treatment of breast cancer has not been established.

Device Story

INTRABEAM System is a miniature, high-dose rate, low-energy X-ray source for intraoperative radiation therapy (IORT). System utilizes spherical applicators (1.5 cm to 5.0 cm diameter) to deliver prescribed radiation doses directly to tumor beds or treatment margins during surgery. Operated by physicians in clinical/surgical settings. Output is localized X-ray radiation; used to provide abbreviated partial breast irradiation (ABPI) in conjunction with whole breast radiotherapy. Clinical benefit includes targeted local control of cancer at the tumor cavity site.

Clinical Evidence

Evidence based on TARGIT-A trial (N=2,232), an international, prospective, randomized, non-inferiority phase 3 trial. Compared IORT using INTRABEAM with whole breast radiotherapy. Primary endpoint: local control of breast cancer. Results showed non-significant recurrence rate difference (1.2% vs 0.95%, p=0.41).

Technological Characteristics

Miniature high-dose rate, low-energy X-ray source. Eight spherical applicator sizes (1.5 cm to 5.0 cm diameter). Class II device (21 CFR 892.5900). Technology and design unchanged from K992577.

Indications for Use

Indicated for patients requiring radiation therapy, specifically for intracavity and intraoperative delivery to tumor beds or treatment margins. Applicable for use in conjunction with whole breast irradiation for breast cancer patients. Not established as a replacement for whole breast irradiation.

Regulatory Classification

Identification

### - Intended Use

The INTRABEAM® System is intended to be used for radiation therapy treatment.

#### Indications for Use

The INTRABEAM® System is indicated for radiation therapy treatments. The INTRABEAM® Spherical Applicators are indicated for use with the INTRABEAM® System to deliver a prescribed dose of radiation to the treatment margin or tumor bed during intracavity and intraoperative radiotherapy treatments.

The INTRABEAM® Spherical Applicators used with the INTRABEAM System are able to deliver a prescribed dose of intraoperative radiation in conjunction with whole breast irradiation, based upon the medical judgment of the physician. The safety and effectiveness of the INTRABEAM System as a replacement for whole breast irradiation in the treatment of breast cancer has not been established.

# Device Description

The INTRABEAM System is a miniature, high-dose rate, low energy X-ray source that emits Xray radiation intraoperatively for the treatment of cancer at the tumor cavity. The INTRABEAM Spherical applicators are accessories to the INTRABEAM System. The INTRABEAM Spherical Applicators received 510(k) clearance in K992577. There are eight sizes of applicators in a set ranging from 1.5 cm to 5.0 cm in diameter. The INTRABEAM Spherical Applicators have not changed in design or technological characteristics as described in K992577.

# TARGIT-A Trial

The modifications to the indications for use are supported by the publication, "Targeted intraoperative radiotherapy versus whole breast radiotherapy for breast cancer (TARGIT-A trial): an international, prospective, randomized, non-inferiority phase 3 trial", published by Vaidya, Joseph, Tobias et al. The study was published in The Lancet (Lancet 2010; 376: 71-72). The TARGIT-A trial was designed to test the hypothesis that in selected patients, substituting whole breast radiotherapy after breast-conserving surgery with targeted intraoperative radiotherapy (IORT) to the tumor bed would not lead to inferior local control of breast cancer. The randomly controlled study (N=2,232) was conducted by physicians around the world using the INTRABEAM System with Spherical Applicators as the only abbreviated partial breast irradiation (ABPI) device. The results of the trial demonstrate a non-significant rate of recurrence between the INTRABEAM Spherical Applicators versus whole breast radiation (1.2% versus 0.95%. p=0.41).

The study concluded that IORT treatment using INTRABEAM Spherical Applicators can be used in conjunction with whole breast radiotherapy.

# ·Substantial Equivalence

Similar to the INTRABEAM System, the MammoSite Radiation Therapy System (RTS) provides a means of delivering radiation therapy in a tumor cavity. Both the MammoSite RTS and the INTRABEAM System with INTRABEAM Spherical Applicators are APBI technology and are comparable in target site and clinical usage.

The INTRABEAM Spherical Applicators that are the subject device for this 510(k) are equivalent to the currently marketed INTRABEAM Spherical Applicators in design, material, radiation doses and principles of operation. Based on the predicate devices and on the findings presented in the TARGIT-A trial publication, the INTRABEAM System with INTRABEAM Spherical Applicators is safe and effective with regards to the proposed indications for use.

## Summary

As described in this 510(k) summary and based on the findings presented in the TARGIT-A trial publication, the INTRABEAM Spherical Applicators are safe and effective for their indications for use.
