WARNING LETTER

CERTIFIED MAIL
RETURNED RECEIPT REQUESTED

Mr. Sean Comer, President
Oncology Tech, LLP
11503 Jones Maltsberger, Suite W-710
San Antonio, Texas 78216

Dear Mr. Comer:

During an inspection of your firm located at the above-referenced address on May 20 through 29, 2008, and June 2, 2008 an investigator from the United States Food and Drug Administration (FDA or Agency) determined that your firm, a specification developer, manufactures and distributes the Mod 1 Compensators that are milled brass blocks used for modulation of beam intensity during radiation therapy as stated in your firm's 510(k) K062781. Under section 201(h) of the Federal Food, Drug, and Cosmetic Act (the Act), 21 U.S.C. § 321(h), these products are devices because they are intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, or are intended to affect the structure or any
function of the body.

This inspection revealed that your devices are adulterated within the meaning of section 501(h) of the Act, 21 U.S.C. § 351(h), in that the methods used in, or the facilities or controls used for, their manufacture, packing, storage, or installation are not in conformity with the Current Good Manufacturing Practice (CGMP) requirements of the Quality System (QS) regulation found at Title 21, Code of Federal Regulations (C.F.R),Part 820.

The FDA investigator issued the observations, which are listed on the Form FDA 483 (List of Inspectional Observations), to you at the end of the inspection on June 2, 2008. You verbally promised to correct the inspectional observations as annotated on the Form FDA 483. FDA follow-up inspections will be necessary to assure that your firm's corrections are adequate.

The violations include, but are not limited to, the following:

Quality System Violations

1. Failure of the management with executive responsibility to ensure that an adequate and effective quality system has been fully implemented and maintained at all levels of the organization, as required by 21 C.F.R. § 820.20. FDA 483 Item 1 referencing FDA 483 items 2-16. Specifically, your firm has not conducted quality audits and established adequate procedures for complaint handling, MDR reporting, purchasing controls, design controls, implementation of corrective and preventive actions, acceptance activities, and computer software validation.

2. Failure to establish and maintain procedures to control the design of the device in order to ensure that specified design requirements are met, as required by 21 C.F.R. § 820.30(a). FDA 483 Item 3. Specifically, your firm has not established written procedures that describe how it performs and documents each step of the design control process for the Mod 1 Compensators, including the design transfer of the device specifications to your contract manufacturer and verification of their production process specifications, and controls of design changes.

3. Failure to establish and maintain device design plans prior to implementing the device design, as required by 21 C.F.R. § 820,30(b). FDA 483 Item 4. Specifically, your firm does not have a design and development plan that defines the specific device design activities and responsibilities that are to be performed between your firm and your contract manufacturer.

4. Failure to establish and maintain procedures for the identification, documentation, validation or verification, review, and approval of design changes before their implementation, as required by 21 C.F.R. § 820.30(i). FDA 483 Item 5. Specifically, your firm has not established written procedures describing how it evaluates, verifies or validates, documents, and approves design changes. For example, at the time of the inspection your website at www.oncologytech.com promoted that your Mod 1 Compensators were engineered from high quality 360 brass or 6061 aircraft-grade aluminum. Your firm has no record of design changes to use of the 6061 aircraft-grade aluminum nor validated this new metal material.

5. Failure to establish and maintain a device design history file for each type of device to include or reference the records necessary to demonstrate that the design was developed in accordance with the approved design plan and the design control requirements of 21 C.F.R. § 820, as required by 21 C.F.R. § 820.30Q). FDA 483 Item 6.

Specifically, other than some engineering drawings, your firm has not maintained a design history file to include documentation of a design and development plan, design reviews, and design verification or validation activities for the Mod 1 Compensators.

6. Failure to establish and maintain process control procedures that describe any process controls necessary to ensure conformance to specifications, as required by21 C.F.R. § 820.70(a). FDA 483 Item 7 and A. Specifically, your firm has not established written procedures for the following manufacturing operations performed by your firm and your contract manufacturer:

a. Receiving encrypted patient treatment plan or data from cancer treatment centers, decrypting it for review and processing, and then encrypting it for storing in your computer server.

b. Methods or instructions for converting decrypted patient treatment data into (b)(4) codes that are then converted into (b)(4) codes for use by your contract manufacturer' s (b)(4) milling machine to mill the brass rounds to produce the finished compensators.

c. Methods or instructions for sending (b)(4) codes to our contract manufacturer for their operators' programming or data entry into the (b)(4) milling machine.

d . Your contract manufacturer's monitoring of their milling process. Your firm reported that some compensators failed their specifications as a result of a loosened bushing on the tooling plate of the (b)(4) milling machine.

7 . Failure to validate software used as part of production and quality system for its intended use according to an established protocol, and failure to document the results of the software validation, as required by 21 C.F.R. § 820.70(i). FDA 483 Item 8. Specifically, your firm has not maintained documentation of the validation of the computer software used to (a) receive encrypted patient treatment data and decrypt/encrypt it; (b) convert decrypted patient treatment data into (b)(4) codes that are converted into b)(4) codes that are then sent to your contract manufacturer's (b)(4) milling machine to produce the compensators.

8. Failure to establish and maintain procedures to ensure that the device history records (DHR) for each batch, lot, or units are maintained to demonstrate that the device is manufactured in accordance with the device master record, as required by 21 C.F.R. § 820.184. FDA 483 Item 10. Specifically, your firm has not established procedures that define what specific device acceptance records and results are to be included in your device history records to demonstrate that the compensators are manufactured per patient treatment data your firm received.
