Japan first country to approve VAL001 patent

Japan has as the first country in the world approved Respiratorius patent application VAL001, "A Pharmaceutical Composition Comprising a HDAC inhibitor and a Steroid and the Use thereof."

The patent gives Respiratorius market exclusivity in Japan for a combination of HDAC inhibitors and steroid pre-treatment before chemotherapy (R-CHOP) in the treatment of diffuse large B-cell lymphoma (DLBCL), a lymphoma that annually affects about 60,000 people in the US and Europe. DLBCL is the most common type of Non-Hodgkin's lymphoma, which comprises 30% of the affected patients in the EU and the US, while in Japan the proportion is significantly higher, 45%.

A clinical Phase I/IIa study of VAL001 is currently running at the Skåne Oncology Clinic, SUS Lund / Malmö, Oncology Clinic at Uppsala University Hospital, and the Cancer Centre, University Hospital in Umeå. In the study, VAL001 is given as pre-treatment prior to standard chemotherapy including rituximab (R-CHOP), in the treatment of diffuse large B-cell lymphoma.

An interim analysis of the Phase I/IIa study results were presented at the end of April 2016. The analysis regards the overall survival of patients treated with VAL001 and R-CHOP, and revealed that 1-year survival rate was 100% and the 2- year survival rate was 95%. For comparison, a matched reference population of 843 patients from the Swedish registry of lymphoma patients treated with R-CHOP alone, showed a 1-year survival of 90% and 2-year survival of 82%. The interim analysis of the VAL001 study outcome was significantly better than those of the reference material for both the 1-year survival (95% significance) and 2-year survival (90% significance).

"The approval of the patent application for VAL001 is of significant importance for the company. Japan is a potentially important market for VAL001 and the approval strengthens our market position”, says CEO Johan Drott in a statement.
