MISSISSAUGA, ON, April 22, 2015 /CNW/ - Nuvo Research Inc. (TSX:NRI), a specialty pharmaceutical company with a diverse portfolio of topical and immunology products, today announced additional details of its new Phase 2 clinical trial (the 2015 WF10 Trial) to assess WF10 for the treatment of allergic rhinitis.
The 2015 WF10 Trial will be a randomized, double-blind, placebo-controlled, single-center trial to assess the efficacy, safety and tolerability of a regimen of five WF10 infusions. The trial will enroll patients who have a moderate to severe allergy to grass and ragweed pollen. Patients' symptoms will be recorded prior to commencement of the grass allergy season in an Environmental Exposure Chamber (EEC), in the field throughout the grass and ragweed allergy seasons and again in the EEC after completion of the ragweed season. The 2015 WF10 Trial is expected to enroll approximately 146 patients and to be completed with topline results available in late Q4 2015 or early Q1 2016. The trial will be conducted in southern Ontario, Canada by Inflamax Research Inc. (Inflamax), a full service, specialty Contract Research Organization (CRO) that specializes in allergy, respiratory and EEC studies. Nuvo's external costs of conducting the trial will be approximately CDN$5.0 million. Commencement of the 2015 WF10 Trial is subject to regulatory approval by Health Canada.
If the 2015 WF10 Trial is successful, the Company plans to continue WF10 development in an independently financed entity that will include the participation of Nuvo shareholders. While Nuvo's management is optimistic that the 2015 WF10 Trial will generate positive results, should the trial be unsuccessful, the Company plans to discontinue WF10 development. The Company has taken steps to curtail spending on a number of WF10 projects and studies planned for 2015 until results of the 2015 WF10 Trial are available.
"This is a critical trial to the future of WF10," said Dr. Henrich Guntermann, President, Europe & Immunology Group. "It is designed to increase the likelihood that patients are exposed to sufficient concentrations of allergens to which they are allergic. We believe that a lack of allergen exposure led to inconclusive results in our 2014 Phase 2 clinical trial and we expect that the results of this new trial will more closely compare to the positive results from our 2010 clinical trial."
About Inflamax Research Inc.
Headquartered in Toronto, Ontario, Inflamax is a full service, global CRO specializing in Proof of Concept, and Phase I through to Phase IV studies in allergy, asthma, ocular, healthy volunteer studies and dermatology. Inflamax Research is a world leader in conduct and design of single and multi-center EEC and field allergy studies. Inflamax has developed the supporting proprietary clinical tools such as ePRO, ePDAT™, to improve data collection and quality, and OCRUP™ for successful patient recruitment.
About Environmental Exposure Chambers
Inflamax's Environmental Exposure Chambers (EEC) are facilities that are validated to tightly regulate temperature and humidity while simulating the level of allergen exposure patients would encounter in their everyday lives. By monitoring patients throughout the exposure, nasal, bronchial and ocular symptoms and signs may be evoked consistently and safely.
WF10 is a solution containing stabilized chlorite ions that focuses on supporting the immune system by targeting the macrophage, a type of white blood cell that coordinates much of the immune system, to regulate normal immune function. WF10 is an infusion therapy currently approved only in Thailand under the name IMMUNOKINE for the treatment of post-radiation-therapy syndromes and adjunctive therapy of diabetic foot ulcers.
About Allergic Rhinitis
Allergic rhinitis is a highly prevalent condition characterized by nasal symptoms (runny, blocked, or itchy nose; chronic sneezing) triggered by an inappropriate immune response to one or more allergens such as pollens, house dust mites and pet dander. Refractory allergic rhinitis patients usually show strong symptoms and do not respond adequately to common forms of treatment such as antihistamines or inhaled corticosteroids. It is estimated that there are 82 million allergy patients in the United States of which approximately 10 million suffer from allergic rhinitis that is refractory.
About the WF10 Trial conducted in 2014 (the 2014 WF10 Trial)
184 patients were enrolled in and 179 patients completed the WF10 Phase 2 allergic rhinitis clinical trial that commenced in March 2014 at 15 sites in Germany. The 16-week trial was a randomized, double-blind, placebo-controlled trial to assess the efficacy, safety and tolerability of a regimen of five infusions of either WF10 or its main constituents (sodium chlorite and sodium chlorate) relative to saline control in patients who suffer from refractory allergic rhinitis with positive skin test to at least one allergen. 46 patients were enrolled in each of 4 arms to receive WF10, WF10 with chlorate removed, WF10 with chlorite removed or placebo (saline). The trial measured total nasal symptom score (TNSS), total ocular symptom score (TOSS) and other secondary endpoints. The trial was designed to confirm the results of the Company's 2010 Phase 2 WF10 proof-of-concept clinical trial for the treatment of allergic rhinitis with WF10 which achieved statistical significance (P<0.001) for its primary endpoint (change in TNSS at week 3). It was also designed to provide information on which WF10 constituent elements are contributing to its therapeutic benefit. As anticipated, the WF10 arm reduced allergy symptoms as evidenced by recorded patient Total Nasal Symptom Scores (TNSS) and Total Ocular Symptom Scores (TOSS). The placebo arm demonstrated an unexpectedly large reduction in patient TNSS and TOSS scores that was greater than those observed in the placebo arm in the Company's 2010 Phase 2 Proof-of-Concept clinical trial (the 2010 Trial). Moreover, in contrast to the 2010 Trial, TNSS and TOSS scores in the placebo arm declined at each successive time point in the 2014 Trial with no tendency to revert towards baseline over time. While the WF10 arm and the two separate arms that included constituent elements of WF10 all performed better than the placebo arm, the differences were not statistically significant. The Company believes that the placebo group in the 2014 Trial did not record as high TNSS and TOSS scores compared to the 2010 Trial due to a longer enrollment period that started later in the allergy season, varying environmental conditions and other factors that resulted in some patients in the 2014 Trial not being exposed to a high enough concentration of the allergens that they were allergic to throughout the trial period.
About the WF10 Trial conducted in 2010 (the 2010 WF10 Trial)
In 2010, the Company conducted a Phase 2 proof-of-concept clinical trial to evaluate WF10 as a treatment for persistent allergic rhinitis. The trial was a 60-subject, randomized, double-blind, placebo-controlled, single-center trial to assess the efficacy and safety of a regimen of five WF10 infusions. The trial met its primary endpoint as measured by the change in Total Nasal Symptom Score (TNSS) from baseline to assessment after three weeks comparing the WF10 group with the placebo group. The trial also met its secondary endpoints as measured by the change in TNSS at six, nine and twelve weeks and in the Total Ocular Symptom Score (TOSS) from baseline to assessment after three, six, nine and twelve weeks. The TNSS and TOSS are validated scales to measure nasal and ocular symptoms associated with allergic rhinitis. The results were statistically significant for all primary and secondary endpoints with p-values less than 0.001 except for the change in TOSS after three weeks for which the p-value was less than 0.003. WF10 was very well tolerated and there were few reported adverse events.
