Scientific Publication on Clinical Studies of VAL001

Respiratorius announces that the high-ranking scientific journal of the American Society of Hematology – Blood Advances, accepted the manuscript "Valproate in Combination with Rituximab and CHOP as First Line Therapy in Diffuse Large B-cell Lymphoma (VALFRID)" for immediate publication.

The scientific article summarizes the implementation and results of the study.

The key results from the Phase I / IIa stuies are presented briefly:

• •      Potential synergistic effect with Rituximab as VAL001 increases the levels of the surface protein CD20.
• •      Overall Survival Analysis for 32 patients treated with VAL001 and R-CHOP shows that 1-year survival is 100% and 2-year survival is 96.8%. Comparative data from a matched reference population of 330 patients from The Swedish lymphoma registry treated with R-CHOP alone provides 1-year survival of 89.6% and 2-year survival of 81.7%. This shows a statistically assured survival benefit (p = 0.034) for patients treated with VAL001 and R-CHOP compared to those treated between 2000–2015 with R-CHOP alone.

Kristina Drott, inventor of VAL001 and author of the article says in a comment: "It is very honorable that the article was accepted after such a quick review which indicates great interest in our results." 

VAL001 is a patented, with patents granted in Europe and Japan, combination of approved and well-tolerated drugs, and is given as pre-treatment for cytostatic treatment (R-CHOP) in the treatment of diffuse large cell B cell lymphoma (DLBCL), the most common type of non-Hodgkin's lymphoma which annually affects about 60,000 people in the US and Europe. The 5-year survival rate for the disease is approximately 65–70%.

Phase I/IIa studies has been conducted at Skåne's oncology clinic, SUS in Lund / Malmö, Akademiska sjukhuset in Uppsala and at Cancer Center, Norrlands University Hospital in Umeå. VAL001 is given as pre-treatment for standard chemotherapy, with the addition of Rituximab (R-CHOP), in the treatment of diffuse large cell B-lymphoma.
