MC2 Therapeutics, a commercial stage pharmaceutical company developing a new standard of topical therapies for chronic inflammatory conditions, announced today that the U.S. Food and Drug Administration (FDA) has approved Wynzora? Cream (calcipotriene and betamethasone dipropionate, w/w 0.005%/0.064%) for once-daily topical treatment of plaque psoriasis in adults 18 years of age or older.

The FDA approval is based on the results of the US Phase 3 clinical trial (1) against active comparator Taclonex? Topical Suspension (calcipotriene and betamethasone dipropionate, w/w 0.005%/0.064%). A total of 794 patients were randomized in this trial and the primary efficacy endpoint was the proportion of patients with PGA treatment success at week 8 defined as at least a 2-grade improvement from baseline in PGA to “clear” or “almost clear”. The difference in PGA treatment success to the active comparator was 14.6% (95% CI; 7.6%, 21.6%) in favor of Wynzora? Cream.

Reduction of itch as defined by at least a 4-point improvement in the 11-point peak pruritus numeric rating scale (NRS) from baseline to week 4 was assessed among patients who had at least a peak pruritus NRS score of 4 at baseline. A higher proportion of patients achieved at least a 4-point improvement in the peak pruritus NRS score at week 4 in the Wynzora? Cream group (60.3%) compared to vehicle (21.4%).

“Wynzora? Cream is a novel topical treatment for plaque psoriasis which offers a unique combination of high efficacy, favorable safety and excellent treatment convenience in a single product,” said Linda Stein Gold, MD, Director of Dermatology Clinical Research at Henry Ford Health System in Detroit, Michigan, and lead principal investigator in the study.

Studies show that more than half of psoriasis patients are dissatisfied with their treatment and that a large proportion of patients are not treated at all (2).

“The FDA approval marks an important milestone for patients with plaque psoriasis", stated Jesper J. Lange, CEO of MC2 Therapeutics and continued: "Our PAD? Technology has uniquely enabled us to develop Wynzora? Cream with no compromises. It drives the compelling efficacy and safety data of Wynzora? Cream and transforms that data into impact for patients through a convenient formulation that allows patients to move on within minutes of a morning routine. It puts patients back in control of therapy and daily life."

Founder and Executive Chairman of MC2 Therapeutics, Mads Clausen concurred: "Wynzora? is a prime example of what we envision PAD? Technology can do to help patients, physicians and payers release the full potential of topical therapies in real world settings."

With the US approval, the recent submission of its marketing authorization application of Wynzora? Cream in EU, and its ongoing interactions with payers, physicians and patient organizations MC2 Therapeutics is well on track to launch Wynzora? Cream in major territories. In addition, MC2 Therapeutics continues development of its pipeline of new topical therapies within major chronic inflammatory indications such as atopic dermatitis, uremic pruritus, lichen sclerosus and dry eye.

About Plaque Psoriasis
Psoriasis is a common, non-contagious, chronic skin disease, with no clear cause or cure. The negative impact of plaque psoriasis on people’s lives can be immense as it affects the appearance of the skin with red, scaly plaques. According to the National Psoriasis Foundation, itch is present in between 70 and 90 percent of psoriasis patients, and together with flaking and scaling, itching is the most burdensome symptom to patients (3,4,5). The appearance of flares of psoriasis can be unpredictable and affects people of all ages. With a reported prevalence of 2-4% of the population psoriasis constitutes a serious health problem with more than 100 million individuals affected worldwide. More than 90% of patients receiving treatment use topical drugs. Patients with psoriatic disease are at an elevated risk of developing other chronic and serious health conditions, including arthritis, cardiovascular diseases, metabolic syndrome, inflammatory bowel disease and depression (5).

About Wynzora? Cream
Wynzora? Cream is a cream-based fixed dose combination of calcipotriene and betamethasone dipropionate for topical treatment of plaque psoriasis. Wynzora? Cream is based on PAD? Technology, which uniquely enables stability of both calcipotriene and betamethasone dipropionate in a convenient-to-use aqueous formulation. In the phase 3 trials conducted at multiple sites in the US and the EU, Wynzora? Cream has demonstrated a unique combination of compelling clinical efficacy, a favorable safety profile and high convenience. These features of Wynzora? Cream hold promise to lead to less treatment discontinuation and overall better patient satisfaction in topical treatment of plaque psoriasis in the real-world setting.
