Bubendorf, Switzerland, Thursday, January 21, 2016 – Proof of concept studies at NBE Therapeutics demonstrated conjugation of CIS Pharma’s Cellophil® Smart Polymer drug carrier to antibodies. Consequently, different linkers were evaluated for loading the drug carrier with anti-cancer moieties. CIS Pharma has successfully loaded its proprietary Cellophil® Smart Polymer drug carriers with model compounds for cancer therapies. CIS Pharma engineers the ADCs to deliver anti-cancer agents to cancerous cells. The Cellophil® drug carrier and the linkers used are targeting control over when, where and how the cytotoxins are released.

About antibody-drug conjugates

Antibody-drug conjugates, or ADCs, are a class of highly potent drugs for the treatment of cancer. ADCs are composed of an antibody that is linked to an anti-cancer payload. The conjugates target cancer cells. Due to the high affinity of the antibodies to tumor cells, the cytotoxic payload is delivered specifically to the cancer tissue, reducing harmful side effects associated with traditional chemotherapeutic agents.
