Knight Therapeutics Announces Launch of WYNZORA® in Canada

MONTREAL, Aug. 20, 2026 (GLOBE NEWSWIRE) -- Knight Therapeutics Inc. ("Knight") (TSX: GUD), a pan-American (ex-US) pharmaceutical company, announced today the launch of WYNZORA^®, a uniform white aqueous cream containing 0.05 mg/g of calcipotriol (CAL) and 0.5 mg/g of betamethasone dipropionate (BDP), in Canada. WYNZORA^® is indicated for the topical treatment of psoriasis vulgaris in adults and adolescents aged 12 and older.¹

“The launch of WYNZORA^® in Canada reflects our commitment to continuing to grow our Canadian platform and bring innovative treatment options to patients. WYNZORA^®'s unique aqueous cream formulation, enabled by PAD Technology™, offers patients and healthcare providers a clinically proven option that combines efficacy with ease of use, an important consideration for a chronic condition that requires long-term management." said Samira Sakhia, President and Chief Executive Officer, Knight Therapeutics Inc.

Knight obtained the Canadian rights to WYNZORA^® through its June 2025 acquisition of the assets of Paladin Pharma Inc. (“Paladin”). Paladin had entered into a license agreement with MC2 Therapeutics Ltd. (“MC2”) to commercialize WYNZORA^® in Canada in November 2024. MC2 is a private pharmaceutical company headquartered in Hørsholm, Denmark and in Guildford, United Kingdom. Knight announced Health Canada approval of WYNZORA^® in December 2025.

About WYNZORA^®

WYNZORA^® is a cream-based fixed dose combination of CAL and BDP for topical treatment of psoriasis vulgaris developed by MC2. WYNZORA^® has a broad mode of action by targeting keratinocyte proliferation and differentiation and inhibiting expression of pro-inflammatory hallmark cytokines such as IL-23, IL-17A/F and TNF-α. In WYNZORA^®, the combination of CAL and BDP has greater anti-inflammatory and anti-proliferative effects than either component alone. WYNZORA^® is uniquely enabled by MC2’s formulation and drug delivery system PAD Technology^TM, allowing an effective convenient-to-use aqueous cream formulation. WYNZORA^® Cream was first approved in the United States by the FDA in July 2020, followed by approvals in Europe in 2021, Australia in November 2024, and Canada in December 2025. 

WYNZORA^® is a registered trademark of MC2. All other trademarks are the property of their respective owners.

About Psoriasis

Psoriasis is a chronic, immune-mediated inflammatory disease of the skin.² It is often characterized by the presence of erythematous plaques, usually covered with silver, flaking scales. These plaques may be itchy or painful; depending on their extent and location, they may also be physically debilitating or socially isolating.^3,4 An estimated 1 million Canadians and 125 million people worldwide, are affected by psoriasis.⁴ Chronic plaque psoriasis (psoriasis vulgaris) is the most common type and accounts for 80% to 90% of cases.⁵ The severity of disease may vary among patients, ranging from mild to moderate to severe.⁵ The clinical course of psoriasis is unpredictable, with fluctuating severity over time.⁶

Common symptoms of psoriasis include itching, redness, flaking and scaling. Itch is considered one of the most bothersome symptoms, with patients reporting itch reduction the most important treatment goal.⁷ Yet, the disease burden of psoriasis extends far beyond the physical dermatological symptoms. Psoriasis is considered a systemic inflammatory disorder, similar to rheumatoid arthritis, Crohn’s disease, and systemic lupus erythematosus.⁸

About MC2 trials

The Health Canada approval was based on the results of two randomized, investigator-blind, vehicle-controlled 8-week phase 3 trials (MC2-01-C2 and MC2-01-C7) in adults, with CAL/BDP gel/suspension included as an active comparator.^9,10 The trials were designed to show superiority of WYNZORA^® to vehicle and non-inferiority to CAL/BDP (50 mcg/g CAL and 0.5 mg/g BDP) gel/suspension.^9,10

Results from both trials demonstrated that WYNZORA^® had superior efficacy compared to vehicle (p < 0.0001) for all confirmatory efficacy endpoints, including Physician Global Assessment (PGA) treatment success and mean percentage change from baseline in modified Psoriasis Area and Severity Index (mPASI) at Week 8 In addition, WYNZORA^® was non-inferior to CAL/BDP gel/suspension at Week 8 for both PGA treatment success and mPASI.^1,9,10

The most frequently reported adverse reactions were application site reactions including irritation, pain, pruritus, eczema, exfoliation, telangiectasia and folliculitis, all occurring at a frequency below 1%.¹
