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 have the potential to generate safe and effective immunologic responses 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 with novel immunomodulators such as Nivolumab. SLP^® immunotherapies are designed to fully harness and direct the body’s own defenses towards fighting the disease. In addition, ISA has begun to develop MyISA^®, a personalized SLP^® immunotherapy, targeting tumor-specific, mutation-derived neo-antigens. These SLP^®s are based on the analysis of immunogenic DNA mutations in a tumor sample, and designed and synthesized for each individual patient.

ISA´s most advanced clinical-stage immunotherapeutic is ISA101, an SLP^® immunotherapy targeting human papillomavirus (HPV)-induced diseases. It is currently in clinical development in advanced and recurrent cervical cancer, incurable HPV16-positive solid tumors (such as small cell carcinoma of head and neck SCCHN) and anal intraepithelial neoplasia (AIN). A clinical Phase II combination trial with ISA101 and Nivolumab is completed and will soon be reported by the MD Anderson Cancer Center in the US. Clinical proof-of-concept has been established 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
