Bristol Myers Squibb's Applications for Deucravacitinib for the Treatment of Moderate to Severe Plaque Psoriasis Accepted by US Food and Drug Administration and Validated by European Medicines Agency
30 November 2021 - - The US Food and Drug Administration has accepted the New Drug Application and the European Medicines Agency has validated the Marketing Authorization Application for deucravacitinib for the treatment of adults with moderate to severe plaque psoriasis, US-based pharmaceutical company Bristol Myers Squibb (NYSE: BMY) said.

The FDA has assigned a Prescription Drug User Fee Act (PDUFA) goal date of September 10, 2022.

These latest regulatory milestones are in addition to the NDA acceptance by Japan's Ministry of Health, Labour and Welfare for deucravacitinib for the treatment of adults with moderate to severe plaque psoriasis, pustular psoriasis and erythrodermic psoriasis.

The regulatory applications are based on positive results from the pivotal POETYK PSO-1 and POETYK PSO-2 trials, which evaluated once daily deucravacitinib in patients with moderate to severe plaque psoriasis versus placebo and Otezla (apremilast).

Deucravacitinib demonstrated significant and clinically meaningful improvements in skin clearance, symptom burden and quality of life measures compared to placebo and Otezla.

Deucravacitinib was well-tolerated with a low rate of discontinuation due to adverse events, with no clinically meaningful lab abnormalities.

Primary results were presented at the American Academy of Dermatology Virtual Meeting Experience in April 2021, and additional analyses were presented at the European Academy of Dermatology and Venereology 30th Anniversary Congress in September 2021.

Bristol Myers Squibb thanks the patients and investigators involved in the POETYK-PSO clinical trial program.

Deucravacitinib (pronounced doo-krav-a-sih-ti-nib) is a first-in-class, oral, selective tyrosine kinase 2 inhibitor with a unique mechanism of action and is the first and only selective TYK2 inhibitor in clinical studies across multiple immune-mediated diseases.

Bristol Myers Squibb scientists designed deucravacitinib to selectively target TYK2, thereby inhibiting signaling of interleukin -23, IL-12 and Type 1 interferon, key cytokines involved in the pathogenesis of multiple immune-mediated diseases.

Deucravacitinib achieves a high degree of selectivity by binding to the regulatory domain of TYK2, resulting in allosteric inhibition of TYK2 and its downstream functions. Deucravacitinib selectively inhibits TYK2 at physiologically relevant concentrations.

At therapeutic doses, deucravacitinib does not inhibit JAK1, JAK2 or JAK3.

Deucravacitinib is being studied in multiple immune-mediated diseases, including psoriasis, psoriatic arthritis, lupus and inflammatory bowel disease.

In addition to POETYK PSO-1 and POETYK PSO-2, Bristol Myers Squibb is evaluating deucravacitinib in three other Phase 3 studies in psoriasis: POETYK PSO-3 (NCT04167462); POETYK PSO-4 (NCT03924427); POETYK PSO-LTE (NCT04036435). Deucravacitinib is not approved for use in any country.
