SAN DIEGO, CA, USA I August 3, 2017 I Avelas Biosciences, Inc., a clinical stage oncology-focused company dedicated to improving cancer patient care from diagnosis through treatment, today announced the first patient has been dosed in its Phase 2 clinical trial of AVB-620 in women with primary, nonrecurrent breast cancer undergoing surgery.

“We’re pleased to have begun dosing patients in our Phase 2 study of AVB-620 in women with breast cancer undergoing surgery, which marks a major milestone for Avelas,” said Carmine Stengone, President & CEO of Avelas Biosciences. “This trial will allow us to confirm the findings from our Phase 1b trial, which demonstrated that AVB-620 could generate fluorescent signals that can distinguish breast cancer from adjacent tissues. We look forward to bringing this essential information to surgeons while they are still in the operating room.”

“Surgical markers like AVB-620 have the potential to reshape cancer surgery by enabling surgeons to visualize cancer and make informed, real-time decisions to improve surgical treatment,” said Steven Chen, M.D., Chief Medical Officer of Avelas Biosciences. “This technology has the potential to reduce the number of re-operations that are needed due to incomplete initial resections, which could result in substantial cost savings and better outcomes for patients.”

This open-label, single-arm, Phase 2 study of AVB-620 is designed to evaluate 100 patients during two separate trial periods. Period 1 will have approximately 30 patients to evaluate conditions to achieve maximal differences in fluorescent signals between malignant and nonmalignant tissue. Period 2 will assess approximately 70 patients to test dosing and imaging conditions determined in Period 1, and the accuracy of AVB-620 imaging data to distinguish between malignant and nonmalignant tissues. Additional information about this clinical trial is available at using the identifier: NCT03113825.

About Avelas Biosciences

Avelas Biosciences is a San Diego-based biotechnology company focused on developing technologies that advance a new standard-of-care for cancer surgery and therapeutic intervention. The company’s lead candidate, AVB-620, has completed a Phase 1b clinical trial assessing safety, pharmacokinetics and fluorescence properties using tissue image analysis. A Phase 2 clinical trial for AVB-620 in breast cancer was initiated in June 2017. In addition, the company is advancing a therapeutic program, which utilizes the same technology platform. Avelas was founded by Avalon Ventures on technology from Roger Y. Tsien, Ph.D., co-winner of the 2008 Nobel Prize in chemistry. For additional information, please visit
