At Avelas Biosciences, we are committed to developing products that bring new, innovative therapies, like pegloprastide (AVB-620), to patients with serious or life-threatening illnesses or conditions. Avelas is developing pegloprastide to improve the ability of surgeons to identify cancerous tissue on the surface of tissue during breast cancer surgery. Pegloprastide must be used in conjunction with a specific imaging device to visualize potentially cancerous tissue during surgery.

At this time, Avelas does not offer an expanded access program and is not accepting expanded access requests for investigational products, such as pegloprastide.

Avelas’ current focus and priority is to complete the product development program for its investigational product(s), such as pegloprastide, in order to obtain the required safety and efficacy data needed for regulatory approval. We believe that focusing our resources on our clinical trial program is the best path forward to bring our investigational product(s) to patients as quickly and safely as possible.

As we continue to develop investigational product(s), we will review our expanded access policy for investigational product(s) and may make updates to this policy.

Patients can gain access to our investigational product(s), such as pegloprastide, by participating in a clinical trial. If you or someone you know would like to learn more about Avelas Biosciences’ clinical trials, we encourage you to view our trials at
