Ultrasound contrast agent developer Sonus Pharmaceuticals has received an action letter from the Food and Drug Administration requesting reanalysis of certain data that may affect product labeling for the firm's EchoGen agent.

The letter is the latest in an ongoing regulatory saga for the Bothell, WA-based firm. Sonus had received an approvable letter for EchoGen in April 1999 indicating that the product could be approved once certain conditions were satisfied.

In September 1999 Sonus submitted a response to the approvable letter, and believed that it had addressed all of the FDA's concerns in the response, according to president and CEO Michael Martino. Sonus will now meet with the agency to discuss how it can best respond to the latest letter.

Ultrasound nonmass breast lesion features may signal malignancy
By Amerigo Allegretto
Some nonmass breast lesion characteristics on ultrasound exams can be considered suspicious for malignancy at screening ultrasound.
November 5, 2024
Images depict a 43-year-old woman with a malignant nonmass lesion that was diagnosed as microinvasive ductal carcinoma. (A) Transverse and (B) longitudinal ultrasound images show a hypoechoic nonmass lesion (solid arrows) with segmental distribution in the left breast. The lesion has associated calcifications (dashed arrows in A). (C) Longitudinal color Doppler ultrasound image shows high vascularity. (D) Magnified image in the mediolateral oblique view from screening mammography shows grouped calcifications (arrows), which are considered a mammographic correlate of the ultrasound-detected nonmass lesion (A radiopaque marker attached to the skin is visible in the image because the mammographic exam was performed after screening breast ultrasound). Ultrasound-guided core needle biopsy and pathologic examination revealed ductal carcinoma in situ, but the lesion was upgraded to microinvasive ductal carcinoma at subsequent surgery (2.5-cm ductal carcinoma in situ, histologic grade II, estrogen receptor-positive, progesterone receptor-positive, human epidermal growth factor receptor type 2-negative).
