– Three additional European patents and market exclusivity granted for the use of key active ingredients of ISA101

Leiden, The Netherlands, June 23, 2015 – ISA Pharmaceuticals B.V., a clinical-stage immunotherapy company focusing on rationally designed immunotherapeutics against cancer and persistent viral infections, today announced it has strengthened the IP position of its lead compound ISA101. The European Patent Office has granted three patents (EP2267132, EP2112157, EP2468763) which relate to the use of HPV antigen-based peptides. ISA101, a novel immunotherapeutic consisting of synthetic long peptides (SLP®s), targets severe diseases triggered by human papillomavirus (HPV) infection.

The patents cover the application of a variety of long peptides derived from the E6 and E7 proteins of HPV, including novel epitopes or peptides with specified features, and provide exclusivity for the treatment of persistent HPV infections and resulting diseases.

ISA101 is based on ISA Pharmaceuticals´ proprietary SLP^® platform and is currently in clinical Phase I/II trials in cervical cancer and anal intraepithelial neoplasia (AIN).

“These three patents ensure broad IP protection for key components of ISA101 in Europe,” said Ronald Loggers, CEO of ISA Pharmaceuticals. “The use of long peptides based on the E6 and E7 proteins of the human papilloma virus has already demonstrated significant therapeutic benefits in the clinic. The strengthened patent position on ISA101 is therefore an important asset for ISA Pharmaceuticals.”

About ISA Pharmaceuticals

ISA Pharmaceuticals B.V. is an immunotherapy company developing rationally designed, fully synthetic immunotherapeutics against cancer and persistent viral infections. The company has built a proprietary immunotherapy platform based on the Synthetic Long Peptide (SLP^®) concept and AMPLIVANT^® technology, which enable the generation of safe and effective drugs with a known mechanism of action. Synthetic long peptides are broadly applicable to multiple targets and ideally suited for monotherapy, as essential components in combination with conventional cancer treatments, and as novel immunomodulators. SLP^® immunotherapies are capable of fully harnessing and directing the body‘s own defenses towards fighting the disease.

ISA101, an SLP^® immunotherapy targeting human papillomavirus (HPV)-induced diseases, is currently in clinical development in cervical cancer and anal intraepithelial neoplasia (AIN). Clinical proof-of-concept has been established with ISA101 in vulvar intraepithelial neoplasia (VIN), a pre-cancerous disease caused by HPV.

The company was founded in 2004 by Aglaia Oncology Fund and is based in Leiden, The Netherlands. For more information, please visit www.isa-pharma.com
